Description

Technical Field

[0001] The utility model relates to the technical field of automobile parts installation, and particularly relates to a plastic buckle for automobile parts installation. Background Art

[0002] In real life, most automobiles use hardware screws for internal component assembly during assembly, but plastic buckles are used for the assembly of some components. For example, wire harness buckles, sunroof buckles, fender buckles, etc. all use plastic buckles at many positions. Existing plastic buckles are assembled with hole positions adapted, and their materials are all composed of plastic materials with a certain toughness. The assembly method of the buckle is simple, but the installation is not firm. Their usage method depends on the mutual matching of the four flat positions of the plastic and the sheet metal for fastening. If the wall thickness of the sheet metal is inconsistent, the tight matching effect cannot be achieved, and certain movement wear and plastic deformation will occur. Multiple sizes need to be mutually matched for the same hole position, and the effect of one match for multiple uses cannot be achieved, which greatly increases the production cost and is not conducive to development. Summary of the Utility Model

[0003] In order to solve the technical problem that existing plastic buckles cannot adapt to sheet thicknesses of multiple sizes and are prone to relative movement wear, the utility model provides a plastic buckle for automobile parts installation.

[0004] To achieve the above object, the utility model provides the following technical solutions: A plastic buckle for automobile parts installation includes a buckle body and a buckle assembly. The inside of the buckle body is a hollow structure. The buckle assembly includes a first buckle and a second buckle. The height of the first buckle is greater than that of the second buckle. At least two first buckles and second buckles are provided, and the first buckles and the second buckles are equally spaced on the four-way positions of the buckle body. One side of the outside of the first buckle and the second buckle is a protruding special-shaped angle, and the inner plane is a flat structure.

[0005] Preferably, the diameter of the entrance end of the buckle body is equal to the diameter of the fixed end.

[0006] Preferably, the bottom cross-section of the buckle body is one of a circle or a polygon.

[0007] By implementing the above technical solutions, the following technical effects are achieved: When the plastic buckle provided by the utility model enters the hole position, the buckle assembly undergoes plastic deformation due to the extrusion of the wall thickness. The lower part of the special-shaped angle is extruded due to the wall thickness, so that the head of the buckle assembly penetrates deeper into the internal hollow structure, and after reaching the same size as the hole position of the plate, it passes through smoothly. After passing through, the buckle further extrudes the plate due to plastic rebound to fix it. Since the heights of the first buckle and the second buckle are inconsistent, they can adapt to different plate thicknesses, and relative movement wear will not occur, achieving the effect of tight matching.

[0009] Description of the Drawing Reference Signs:

[0010] 1. Buckle body; 2. First buckle; 3. Second buckle; 4. Hollow structure. Detailed Embodiment

[0011] In order to better understand the technical solution of the present utility model, the embodiments provided by the present utility model will be described in detail below with reference to the drawings.

[0012] Refer to Figure 1 , an embodiment of the present utility model provides a plastic buckle for automobile parts installation, including a buckle body 1 and a buckle assembly. The inside of the buckle body 1 is a hollow structure 4. The buckle assembly includes a first buckle 2 and a second buckle 3. The height of the second buckle 3 is greater than that of the first buckle 2. There are at least two first buckles 2 and second buckles 3, and the first buckles 2 and second buckles 3 are equally spaced on the four-way positions of the buckle body 1. The outer sides of the first buckles 2 and second buckles 3 are outwardly protruding special-shaped corners, and the inner cavity is a planar structure.

[0013] Therefore, the plastic buckle provided by the present utility model can adapt to different plate thicknesses due to the different heights of the first buckle 2 and the second buckle 3. When the plastic buckle is assembled, the special-shaped corners further assist in fixing the plate. An upward elastic force is generated on one side of the special-shaped corners on the buckle assembly, and the planar side bends downward, enabling it to smoothly enter the metal plate hole. No relative movement wear will occur during the assembly process. After assembly, the special-shaped corners of the buckle assembly further rebound and lock, achieving a tight fit effect. On the other hand, when the buckle assembly rebounds, a part of the special-shaped corner structure is stuck on the inclined surface of the plate, and the buckle assembly maintains a certain bending, further achieving the anti-detachment effect.

[0014] Based on the above embodiment, in other embodiments, further, the diameter of the entry end of the buckle body 1 is equal to the diameter of the fixed end, that is, the diameters of the front and rear ends of the plastic buckle after fixation are the same, which means there is no gap between the plate and the plastic buckle, and the plastic buckle can further closely cooperate with the plate.

[0015] Based on the above embodiment, in other embodiments, further, the bottom cross-section of the buckle body 1 is one of a circle or a polygon, and various shapes can be set. In this embodiment, the bottom cross-section of the buckle body 1 is a circle.

[0016] The main principle of a plastic buckle for automobile parts installation provided by this utility model patent is to rely on the plasticity principle inherent in the plastic material to achieve clamping and fastening. During operation, when the plastic buckle enters the hole position of the board, the buckle assembly undergoes plastic deformation due to the extrusion of the wall thickness. The lower part of the special-shaped angle is squeezed by the wall thickness, causing the head to penetrate deeper into the internal central control part, and it can pass smoothly after reaching the same size as the hole position of the board. Subsequently, due to plastic rebound, the buckle assembly will further squeeze the board to fix it. Since the heights of the first buckle and the second buckle are inconsistent, it is applicable to various board thicknesses and will not cause relative movement wear after fixation, achieving the effect of tight fit.

[0017] The above has introduced in detail a plastic buckle for automobile parts installation provided by the embodiments of this utility model. For those of ordinary skill in the art, based on the idea of the embodiments of this utility model, there will be changes in the specific implementation manners and application scopes. In summary, the content of this specification should not be construed as a limitation to this utility model.
