Abstract

An angle adjusting mechanism for a mouthpiece bearing portion of a telephone includes a hinge, a guiding member, a connecting member, a pushing member, a first wheel, and a second wheel. The hinge and the guiding member are fixed on opposite ends of the connecting member. The first wheel is fixed on the pushing member, and the second wheel is fixed on the mouthpiece bearing portion. The first wheel and the second wheel engage together and an end of the pushing member is connected to the guiding member. The hinge can rotate to slide the pushing member to rotate the first wheel. The second wheel turns to achieve a constant angle for the handset bed even if main body of telephone is propped up to an angle from a supporting surface.

Claims

1. An angle adjusting mechanism for adjusting an angle of a mouthpiece bearing portion of a telephone, comprising:

a hinge mounted in the telephone;

a guiding member;

a connecting member connecting the hinge and the guiding member;

a pushing member slidably connected to the guiding member;

a first wheel fixed on the pushing member and away from the guiding member; and

a second wheel fixed on the mouthpiece bearing portion and engaged with the first wheel;

wherein when the hinge is rotated to drive the connecting member and the guiding member to rotate, the pushing member slides in the guiding member to drive the first wheel to rotate, and the second wheel turns in response to the first wheel rotating, thereby rotating the mouthpiece bearing portion.

2. The angle adjusting mechanism of claim 1, wherein the hinge comprises:

a rotational part connected to the connecting member;

a fixed part fixed in the telephone; and

an interconnecting part coupling the rotational part to the fixed part;

wherein the rotational part has a rotational connection with the interconnecting part.

3. The angle adjusting mechanism of claim 2, wherein the interconnecting part is attached to the fixed part, a receiving groove is defined on the interconnecting part, and the receiving groove faces the rotational part.

4. The angle adjusting mechanism of claim 3, wherein the rotational part comprises a first fixation element extending from an end of the rotational part, the first fixation element is adjacent to the interconnecting part, and a free end of the first fixation element is received in receiving groove in rotation.

5. The angle adjusting mechanism of claim 4, wherein the rotational part further comprises a first fasten key formed on the first fixation element, the first fasten key perpendicularly extends away from a periphery of the first fixation element, and the first fasten key and the first fixation element connect to fix the connecting member.

6. The angle adjusting mechanism of claim 5, wherein a first fixing hole and a first keyseat are defined on the connecting member, the free end of the first fixation element is inserted through the first fixing hole, the first fasten key is received in the first keyseat and abuts the interconnecting part.

7. The angle adjusting mechanism of claim 1, wherein the guiding member comprises a ring groove, the ring groove penetrates through the guiding member, and an end of the pushing member away from the first wheel is received in the ring groove.

8. The angle adjusting mechanism of claim 7, wherein the guiding member further comprises a second fixation element, and the second fixation element is formed beside the ring groove.

9. The angle adjusting mechanism of claim 8, wherein the guiding member further comprises a second fasten key formed on the second fixation element, the second fasten key perpendicularly extends from periphery of the second fixation element, and the second fixation element and the second fasten key connect and fix the connecting member.

10. The angle adjusting mechanism of claim 9, wherein a second fixing hole and a second keyseat are defined on the connecting member, and a free end of the second fixation element is inserted through the second fixing hole, and the second fasten key is received in the second keyseat.

11. The angle adjusting mechanism of claim 7, wherein the pushing member comprises:

a main body;

a slider received in the ring groove of the guiding member; and

a holding element connected to the mouthpiece bearing portion;

wherein the slider and the holding element are respectively formed on opposite ends of the main body.

12. The angle adjusting mechanism of claim 11, wherein a distance between a top wall and a bottom wall of the ring groove is constant, and the slider slides along the top wall and the bottom wall of the guiding member.

13. The angle adjusting mechanism of claim 11,

wherein the main body comprises a base board, a first side wall, and a second side wall, the first side wall and the second side wall are respectively formed on opposite sides of the base board;

and

wherein the base board, the first side wall, and the second side wall together define a cavity for receiving the first wheel.

14. The angle adjusting mechanism of claim 13, wherein the base board is curved, and a width of the first side wall and the second side wall gradually decreases from the holding element towards the slider.

15. The angle adjusting mechanism of claim 13, wherein the holding element is formed on the first side wall, and the holding element extends from the first side wall away from the second side wall.

16. The angle adjusting mechanism of claim 15, wherein an opening is defined on the second side wall, and the holding element faces the opening.

17. The angle adjusting mechanism of claim 16, wherein a spindle is configured on the mouthpiece bearing portion, the second wheel is fixed on the spindle, and a free end of the spindle passes through the opening of the second side wall to be received in the holding element.

18. The angle adjusting mechanism of claim 17, wherein the spindle extends away from a side of the mouthpiece bearing portion.

19. The angle adjusting mechanism of claim 13,

wherein the main body further comprises two location holes, the two location holes are defined on the first side wall and the second side wall, the two location holes are adjacent to the holding element;

and

wherein the main body further comprises two limiting holes, each limiting hole is further recessed from a corresponding location hole away from the base board.

20. The angle adjusting mechanism of claim 19,

wherein the first wheel comprises two locating blocks formed beside the teeth of the first wheel, the two locating blocks are received in the two location holes;

and

wherein the first wheel further comprises two limiting blocks, each limiting block is formed on a corresponding locating block, and the two limiting blocks are received in the two limiting holes of the pushing member.
