Detailed ways

Referring to the drawings showing embodiments of the invention, the invention will be described in more detail below. However, the invention may be embodied in many different forms and should not be construed as being limited to the embodiments set forth herein. Rather, these embodiments are presented so that this disclosure will be thorough and complete, and the scope of the invention is fully understood by those skilled in the art. In the drawings, the size and relative dimensions of layers and regions may be exaggerated for clarity.

Example 1

1-14, the present invention provides a bracket connecting structure for connection between a first bracket member 1 and a second bracket member 2, the bracket connecting structure including a card disposed on the first bracket member 1. The mouth 2 and the buckle 4 disposed on the second bracket 2; wherein the bayonet 2 includes a connecting portion 201 and a latching portion 202, the gap of the engaging portion 202 is smaller than the gap of the insert portion 201; The long-side convex body 401 having a circular arc-shaped cross section is connected to the second bracket member 3 via the connecting portion 402, and the length of the connecting portion 402 is smaller than the length of the male buckle body 401. The length of the main body 401 is equal to or smaller than the gap of the insertion portion 201 and larger than the gap of the engaging portion 202.

When the first bracket member 1 is connected to the second bracket member 2, the male button body 401 is first inserted into the bayonet 2 from the insertion portion 201 until the connecting portion 402 is placed in the insertion portion 201, and the male button body 401 extends to the card. The back side of the mouth 2 is then moved to the side of the engaging portion 202, so that the connecting portion 402 is snapped into the engaging portion 202, and the connecting portion 402 and the engaging portion 202 are interference-fitted to achieve a fixed connection, and at the same time convex Both ends of the buckle main body 401 are pressed against both sides of the back surface of the bayonet 2 to achieve further fixing.

The bracket connecting structure provided by the invention has the protruding buckle inserted into the bayonet and moved therein, the insertion and the clamping fixing by the change of the gap in the bayonet and the structural shape of the buckle, the structure is simple, and the disassembly and assembly is convenient; After being connected with the bayonet, during the use of the bracket, the length direction of the buckle (ie, the left and right direction as shown in FIG. 3) is subjected to great torque. In the present invention, the body of the buckle is designed to have a curved cross section. Therefore, the strength of the buckle body is greatly enhanced, so that the buckle is less likely to be deformed and is not easily broken, so that the connection between the first bracket member and the second bracket member is more firm and stable, and the service life is greatly prolonged.

In this embodiment, the cross-section of the male body 401 is preferably semi-circular in shape to ensure the best torque resistance; of course, in other embodiments, the cross-section of the male body 401 may not be semi-circular, depending on the specific Need to adjust.
