It should be understood that the specific embodiments described herein are only used to explain the present invention and are not used to limit the present invention.

[0031] As Figures 1 to 4 shown: A double-screw anti-rotation structure of a button 20 according to the present invention includes:

[0032] A body 10 having an assembly cavity;

[0033] Two buttons 20 are provided and are movably installed in the assembly cavity;

[0034] Two corresponding screw rods 30 are provided, and one end of each screw rod is in driving connection with the button 20. A limiting part 31 is provided on the screw rod 30;

[0035] An anti-rotation clip 40 has snap rings 41 at both ends. A anti-rotation part 411 that is in limiting cooperation with the limiting part 31 along the circumferential direction of the screw rod 30 is provided on the snap ring 41.

[0036] In this embodiment, one of the two snap rings 41 is further provided with a positioning portion 412, and the positioning portion 412 is in positioning cooperation with the thread of the screw 30 along the axial direction of the screw 30, preventing the anti-rotation clamp 40 from separating from the screw 30, and the structure is stable.

[0037] In this embodiment, the other of the two snap rings 41 is movably and relatively arranged with the screw 30 along the axial direction of the screw 30, without interfering with the relative independent movement of the two screws, and the structure is simple and ingenious.

[0038] In this embodiment, the positioning portion 412 is a thread provided on the inner wall of the snap ring 41 and mating with the thread of the screw 30.

[0039] In this embodiment, the anti-rotation clamp 40 includes a connecting arm 42, and the two snap rings 41 are arranged on both sides of the connecting arm 42.

[0040] In this embodiment, the connecting arm 42 includes a first connecting arm 42a and a second connecting arm 42b that are telescopically mated, and the two snap rings 41 are respectively arranged at the ends of the first connecting arm 42a and the second connecting arm 42b that are far away from each other.

[0041] In this embodiment, the ends of the first connecting arm 42a and the second connecting arm 42b that are close to each other are in threaded cooperation, so that the first connecting arm 42a and the second connecting arm 42b can be telescopically mated relatively, which is convenient for pre-assembly during the production process and prevents the two parts from loosening.

[0042] In this embodiment, one of the limiting portion 31 and the anti-rotation portion 411 is a limiting rib, and the other of the limiting portion 31 and the anti-rotation portion 411 is a limiting groove.

[0043] In this embodiment, the limiting portion 31 is a limiting groove 31 extending along the axial direction of the screw 30, the anti-rotation portion 411 is a limiting rib 411 correspondingly arranged on the inner wall of the snap ring 41, and the length of the limiting groove is not less than the moving stroke of the button relative to the body, preventing the movement of the button from being restricted and ensuring the normal use function of the button.

[0045] During installation, directly snap the two snap rings 41 onto the two screws 30 respectively, and make the limiting rib 411 snap into the limiting groove 31. The limiting rib 411 and the limiting groove 31 form a circumferential limiting cooperation, and the two snap rings 41 are fixedly connected together through the connecting arm 42, and the two snap rings 41 cannot move relatively, so that the screw 30 cannot rotate relative to the snap ring 41;

[0046] During use, since one of the two snap rings 41 is provided with a positioning portion 412, the positioning portion 412 is in positioning cooperation with the thread of the screw 30 along the axial direction of the screw 30; the other of the two snap rings 41 is in relative movable cooperation with the screw 30 along the axial direction of the screw 30, thereby not interfering with the relative independent movement of the two screws.

[0047] The structure of the anti-rotation clamp 40 of this solution is simple and its length is adjustable, and the connection structure between the anti-rotation clamp 40 and the screw 30 is simple. It can not only prevent the screw 30 from loosening, but also prevent the screw 30 from shaking. Moreover, it is convenient for disassembly and assembly, has strong versatility, saves costs, and is suitable for popularization.
