Abstract

A belt head includes a seat, a buckle portion, an engaging portion and a button. The seat has a front side portion having two narrow side surfaces facing to each other and a rear side portion used to connect and fix an end of a strap. The buckle portion has a connecting base connected with the front side portion and a fastening base which has a passage enabling the other end of the strap to pass through and a fastener for fastening or releasing the strap. The engaging portion is disposed on the front side portion and is movable between a first and second positions to engage with and release from a blocking member of the connecting base. The button is located on one of the narrow side surfaces of the front side portion for controlling the engaging portion to move between the first and second positions.

a first engaging portion disposed on the front end portion of the seat and being movable between a first position where the first engaging portion engages with the first blocking member and a second position where the first engaging portion releases from the first blocking member; and

a first button located at one of the narrow side surfaces of the front end portion of the seat, the first button configured to control the first engaging portion to move between the first position to engage with the first blocking member and the second position to release from the first blocking member.

2. The belt head of claim 1, wherein the first engaging portion is pivotably connected with the front end portion of the seat and has a hook at one end thereof used to engage with or release from the first blocking member;

the first button extends from the other end of the first engaging portion and protrudes from one of the narrow side surfaces, wherein a pivot joint where the first engaging portion is pivotably connected with the front end portion of the seat is located between the hook of the first engaging portion and the first button and is closer to the first button.

3. The belt head of claim 2, further comprising a first resilient member located between the first engaging portion and the front end portion of the seat for providing an elastic force enabling the hook of the first engaging portion to bounce toward the first blocking member.

4. The belt head of claim 3, further comprising a first supporting block protruding from the front end portion of the seat, the first supporting block having a side surface facing the hook of the first engaging portion, wherein while the hook of the first engaging portion is engaged with a side of the first blocking member, the opposite side of the first blocking member abuts against the side surface of the first supporting block.

5. The belt head of claim 1, further comprising a second engaging portion disposed on the front end portion of the seat and a second button located at the other narrow side surface of the front end portion of the seat;

wherein the connecting base of the buckle portion further has a second blocking member, the second engaging portion is movable between a first position where the second engaging portion engages with the second blocking member and a second position where the second engaging portion releases from the second blocking member, and the second button is configured to control the second engaging portion to move between the first position to engage with and the second position to release from the second blocking member.

6. The belt head of claim 5, wherein the second engaging portion is pivotably connected with the front end portion of the seat and has a hook at one end thereof used to engage with or release from the second blocking member;

the second button extends from the other end of the second engaging portion and protrudes from the other narrow side surface, wherein a pivot joint where the second engaging portion is pivotably connected with the front end portion of the seat is located between the hook of the second engaging portion and the second button and is closer to the second button.

7. The belt head of claim 6, further comprising a second resilient member located between the second engaging portion and the front end portion of the seat for providing an elastic force enabling the hook of the second engaging portion to bounce toward the second blocking member.

8. The belt head of claim 7, further comprising a second supporting block protruding from the front end portion of the seat, the second supporting block having a side surface facing the hook of the second engaging portion, wherein while the hook of the second engaging portion is engaged with a side of the second blocking member, the opposite side of the second blocking member abuts against the side surface of the second supporting block.

9. The belt head of claim 1, wherein the connecting base is pivotably connected with the fastening base.

10. A belt head comprising a seat and a buckle portion detachably assembled with each other, and two engaging portions and two buttons disposed on one of the seat and the buckle portion;

wherein an end of the seat is used to connect and fix an end of a strap;

the buckle portion is used to enable the opposite end of the strap to pass through to fasten or release the opposite end of the strap;

one of the engaging portions is located opposite to another engaging portion and each of the engaging portion is movable between a first position where the buckle portion is restricted from detaching from the seat and a second position where the buckle portion is allowed to detach from the seat;

one of the buttons is located opposite to another button and each of the buttons is used to control the corresponding engaging portion to move between the first position and the second position.

11. A belt head comprising:

a seat for connecting with an end of a belt;

a fastening base having a passage that allows the opposite end of the belt to pass through and a fastener for fastening or releasing the opposite end of belt; and

a connecting base connected with the fastening base; and

two resilient engaging devices respectively disposed on two opposite sides of the seat for elastically engaging with or releasing from the connecting base.

12. The belt head of claim 11, wherein the fastening base is rotatable with respect to the connecting base.

13. The belt head of claim 12, wherein an end of the fastening base has two hinge holes on two opposite sides thereof, the connecting base has a hinge portion at an end thereof, the hinge portion is located between the two opposite sides of the end of the fastening base and has a lateral hole corresponding to the two hinge holes of the end of the fastening base;

a pivot shaft is inserted into the two hinge holes of the fastening base and the lateral hole of the hinge portion of the connecting base for engaging the fastening base and the connecting base.

14. The belt head of claim 11, wherein the connecting base has two blocking members respectively disposed in two slots formed in the opposite sides of an end of the connecting base, and each of the blocking members is fixed on two opposite walls of the corresponding slot;

the seat has a connecting recess at one end thereof for connecting with the end of the belt, and the seat further has two supporting blocks disposed on two opposite sides of the opposite end thereof and corresponding to the two blocking members of the connecting base, each of the supporting block protrudes toward the connecting base for enabling the corresponding blocking member to abut against, the seat further has two hinge recesses formed in the two opposite sides of the opposite end thereof and respectively located out of the two supporting blocks;

the two resilient engaging devices are disposed in the two hinge recesses of the seat correspondingly, and each of the resilient engaging devices has a pin, a resilient member and an engaging portion, the pin is fixed on two side walls of the corresponding hinge recess of the seat, the resilient member is sleeved around the pin, the engaging portion is pivotably connected to the connecting base by the pin and is configured to bounce toward the corresponding block member by elastic force provided by the resilient member.

15. The belt head of claim 14, wherein the engaging portion of each of the two resilient engaging devices has a hook and a button at two opposite ends thereof respectively, the hook faces the corresponding blocking member, the button protrudes outwardly and is used to control the hook to bounce toward the corresponding blocking member for engaging with the corresponding blocking member or releasing from the corresponding blocking member.
