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 pivotably connected with the front end portion of the seat, the first engaging portion having a hook at one end thereof used to engage with or release from the first blocking member 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;

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;

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;

a first supporting block protruding from the front end portion of the seat, wherein while the hook of the first engaging portion is engaged with a side of the first blocking member, the first supporting block inserts into the connecting base to make the first blocking member located between the first supporting block and the first engaging portion;

a second engaging portion pivotably connected with the front end portion of the seat, the second engaging portion having a hook at one end thereof used to engage with or release from the second blocking member and being 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;

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;

a second button located at the other narrow side surface of the front end portion of the seat, the second button 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; and

a second supporting block protruding from the front end portion of the seat, wherein while the hook of the second engaging portion is engaged with a side of the second blocking member, the second supporting block inserts into the connecting base to make the second blocking member located between the second supporting block and the second engaging portion.

2. The belt head of claim 1, wherein the first button extends from the other end of the first engaging portion and protrudes from one of the narrow side surfaces;

the front end portion of the seat has a pivot joint where the first engaging portion is pivotably connected with the front end portion of the seat, the pivot joint is located between the hook of the first engaging portion and the first button, and the pivot joint is closer to the first button than the hook of the first engaging portion.

3. The belt head of claim 1, wherein the first supporting block has a side surface facing the hook of the first engaging portion;

while the hook of the first engaging portion is engaged with the side of the first blocking member, the opposite side of the first blocking member abuts against the side surface of the first supporting block.

4. The belt head of claim 1, wherein the second button extends from the other end of the second engaging portion and protrudes from the other narrow side surface;

the front end portion of the seat has a pivot joint where the second engaging portion is pivotably connected with the front end portion of the seat, the pivot joint is located between the hook of the second engaging portion and the second button, and the pivot joint is closer to the second button than the hook of the second engaging portion.

5. The belt head of claim 1, wherein the second supporting block has a side surface facing the hook of the second engaging portion;

while the hook of the second engaging portion is engaged with the side of the second blocking member, the opposite side of the second blocking member abuts against the side surface of the second supporting block.

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

7. A belt head for connecting with a strap, the belt head comprising:

a seat having a front end portion and a rear end portion, the front end portion having a first blocking member and a second blocking member, the rear end portion being used to connect and fix an end of the strap;

a buckle portion having a connecting base and a fastening base, the connecting base having two narrow side surfaces facing each other and being spaced apart with a distance, the width of each of the narrow side surfaces being smaller than the distance;

wherein the connecting base is detachably assembled to the front end portion of the seat;

the fastening base has a passage that allows the other end of the strap to pass through, and a fastener for fastening or releasing the other end of the strap;

a first engaging portion pivotably connected with the connecting base, the first engaging portion having a hook at one end thereof used to engage with or release from the first blocking member 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;

a first resilient member located between the first engaging portion and the connecting base for providing an elastic force enabling the hook of the first engaging portion to bounce toward the first blocking member;

a first button located at one of the narrow side surfaces of the connecting base, 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;

a first supporting block protruding from the connecting base, wherein while the hook of the first engaging portion is engaged with a side of the first blocking member, the first supporting block inserts into the front end portion of the seat to make the first blocking member located between the first supporting block and the first engaging portion;

a second engaging portion pivotably connected with the connecting base, the second engaging portion having a hook at one end thereof used to engage with or release from the second blocking member and being 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;

a second resilient member located between the second engaging portion and the connecting base for providing an elastic force enabling the hook of the second engaging portion to bounce toward the second blocking member;
