Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative work belong to the protection scope of the present invention.

Example 1

As shown in fig. 1 to 6, the anti-releasing fixing buckle 6 with a limiting function includes a limiting surface, a clamping surface, a pressing surface 5 and a guiding inclined surface 3, and a cavity structure 4 is disposed between the surfaces.

The limiting surface comprises a first limiting surface 1-1 and a second limiting surface 1-2, the first limiting surface 1-1 is tightly attached to the A plastic ornament 7 during assembly, and the limiting function is achieved through the two limiting surfaces after the buckle is assembled; the two sides of the first limiting face 1-1 and the two sides of the second limiting face 1-2 are connected through clamping faces, the two clamping faces are respectively provided with a first elastic clamping jaw 2-1 and a second elastic clamping jaw 2-2, the two elastic clamping jaws are symmetrically arranged, and each elastic clamping jaw consists of a guide portion and a clamping portion. Spacing face and joint face top are equipped with pressing surface 5, and the bottom is equipped with direction inclined plane 3.

The first limiting surface 1-1 and the second limiting surface 1-2 are used for limiting through the two limiting surfaces after the buckle is assembled;

the cavity structure 4 provides an elastic space for the elastic claw;

the pressing surface 5 is matched with the elastic jaw I2-1 and the elastic jaw II 2-2 to prop against the B plastic ornament 8, so that the elastic jaw is prevented from loosening and losing efficacy;

the guide inclined plane 3 is of a frustum structure, so that the buckle is convenient to mount, and the clamping stagnation of the buckle 6 during assembly is prevented;

the utility model discloses a theory of operation does: before the buckle is installed, the plastic ornament B firstly passes through the square hole of the plastic ornament A through the installation rib with the installation hole, during the assembly, the buckle passes through the installation hole of the plastic ornament B, Y in figure 5 is the installation direction of the plastic ornament B, and X is the installation direction of the buckle.

The utility model has the advantages that: the buckle compromises fixing, anticreep and limit function, satisfies two plastics and decorates the fixed of part. The elastic claws and the pressing surface of the buckle are propped against the B plastic ornament, and the assembly direction of the buckle and the pull-out force direction of the B plastic ornament are normal, so that the buckle cannot be loosened due to external force, and the anti-falling function is realized. When the buckle is installed, the guide part of the elastic claw firstly penetrates through the installation hole of the B plastic ornament, the claw is compressed and then rebounds to enable the clamping part and the edge of the installation hole of the B plastic ornament to realize the clamping function, and meanwhile, the buckle pressing surface abuts against the B plastic ornament.
