Description

Technical Field

[0001] The utility model relates to the technical field of intercoms, in particular to an angle-adjustable back clip for an intercom. Background Art

[0002] A walkie-talkie is a two-way mobile communication tool that allows conversations without the need for any network support. Its main principle is to transmit sound signals through radio waves. When the user speaks, the walkie-talkie converts the sound signals into electrical signals, and then transmits them through the antenna. After the recipient's walkie-talkie receives these signals, it converts them back into sound. Then the user can hear what the other party is saying, thus realizing instant communication. Therefore, it is widely used in large-scale events, construction sites, hotel management and other occasions that require frequent communication.

[0003] For the convenience of use, existing intercoms are often equipped with a back clip on the back of the intercom. The back clip consists of a torsion spring and a clamp. By pressing one end of the clamp to open the other end of the clamp, the intercom can be clamped to the collar or belt under the action of the torsion spring.

[0004] However, during use, since the back clip is fixedly connected to the walkie-talkie, when the angle of the walkie-talkie needs to be adjusted in some specific working environments (squatting or bending over), the walkie-talkie needs to be removed from the fixed position before the corresponding adjustment can be made. The flexibility is poor and cannot meet the use requirements.

[0005] In view of this, the inventor conducted in-depth research on the above-mentioned issues, which led to the creation of this case. Utility Model Content

In this embodiment, the rotating member 13 is a hollow shaft or a bearing, and the connecting portion 12 is also connected to a back clip that can rotate relative to the cover 10. The back clip includes a back plate 20 and a clamping plate 30 pivotally connected to the side of the back plate 20 facing away from the cover 10. A connecting member 21 extending to the inside of the rotating member 13 is penetrated on the top of the back plate 20. In this embodiment, the connecting member 21 is a rivet, and a pivot is also provided between the clamping plate 30 and the back plate 20. 41 and a torsion spring 42, with the connecting portion 12 as the base point, two first annular grooves 14 and second annular grooves 15 with different diameters are concentrically provided around the connecting portion 12 in the circumferential direction. In the present embodiment, the diameter of the second annular groove 15 is larger than the diameter of the first annular groove 14, and the bottom wall of the first annular groove 14 is further provided with a plurality of positioning grooves 141 evenly spaced along the circumferential direction, a first annular protrusion 22 for snapping into the second annular groove 15 is convexly provided on one side of the back plate 20 facing the machine cover 10, and two positioning portions 251 arranged along a straight line are provided inside the first annular protrusion 22, and each positioning portion 251 is convexly provided with a positioning protrusion 252 for snapping into the positioning groove 141 on one side facing the machine cover 10.

[0026] When in use, the angle can be adjusted by rotating the intercom, and since the positioning groove 141 and the positioning protrusion 252 are provided, the positioning protrusion 252 will be stuck in the corresponding positioning groove 141 after the angle is adjusted, thereby achieving a locking effect, so that the intercom can remain stable.

[0027] Reference Figures 1 to 6The side of the back plate 20 facing the machine cover 10 is recessed with a step hole 24 for accommodating the connecting part 12, and both sides of the step hole 24 are recessed with positioning grooves 25 arranged through, and each positioning groove 25 is convexly provided with a positioning part 251; the side of the back plate 20 facing away from the machine cover 10 is convexly provided with a circular boss 26 for accommodating the connecting member 13, the circular boss 26 is hollow inside, and the circular boss 26 is provided with the above-mentioned step hole 24, and the lower part of the circular boss 26 is convexly provided with a stop block 261 arranged along the width direction of the back plate 20, and the lower part of the stop block 261 is convexly provided with a first mounting seat 27, and the first mounting seat 27 is provided with a through-set stopper 26 arranged along the width direction of the back plate 20. The first connecting hole 271, two second mounting seats 31 are protruding on both sides of the side of the splint 30 facing the back plate 20, and the second mounting seat 31 is provided with a second connecting hole 311 which is arranged along the width direction of the splint 30. The torsion spring 42 is installed on the first mounting seat 27, and one end of the pivot 41 passes through the second connecting hole 311 on one side of the splint 30, the spring hole of the torsion spring 42, and the first connecting hole 271 in sequence, and then passes through the second connecting hole 311 on the other side of the splint 30. In this way, when in use, the splint 30 can be opened by pressing one end of the splint 30, and after loosening the splint 30, the opened end of the splint 30 returns to its original position under the action of the torsion spring 42.

[0028] Reference Figures 1 to 6 The torsion spring 42 includes a first spring body 421, a second spring body 422, and a push arm 423 connected between the first spring body 421 and the second spring body 422. There is a gap between the first spring body 421 and the second spring body 422, and the push arm 423 abuts against the above-mentioned stop block 261. The first spring body 421 and the second spring body 422 are respectively extended outwardly with elastic arms 424; the first mounting seat 27 is respectively provided with first limit blocks 28 for limiting the displacement of the first spring body 421 and the second spring body 422 on both sides, and the outer sides of the two first limit blocks 28 opposite to each other are both concavely provided with first clearance grooves 29 for accommodating the second mounting seat 31. In the embodiment, the first clearance groove 29 is semi-arc-shaped; a second clearance groove 32 for accommodating the first spring body 421, the second spring body 422 and the first mounting seat 27 is recessed between the two second mounting seats 31. In the present embodiment, the second clearance groove 32 is semi-arc-shaped, and a through hole 33 is also provided on the top of the splint 30 facing the back plate 20, and second limit blocks 34 are protruding on both sides of the through hole 33. The bottom of the second limit block 34 is recessed inwardly with a limit groove 341, and the two elastic arms 424 are respectively supported in the two limit grooves 341.
