Most of the connections between sheet metal parts in existing automobiles or household appliances adopt bolt connection, which is complicated, time-consuming and labor-intensive to disassemble and assemble, greatly increasing the working difficulty of the workers. Moreover, the buckle is suitable for sheet metal parts, and after being installed in the buckle, the sheet metal hole is not waterproof, and rust is easily generated inside the sheet metal part, thereby shortening the service life of the sheet metal part.

[0003] In the prior art, CN219655034U discloses a W-shaped waterproof buckle. Two wing plates are inserted into the mounting hole, and the bottom plate is squeezed, so that the wing plates are squeezed into the mounting hole, and the sealing ring is tightly attached around the mounting hole, thereby blocking rainwater from entering the mounting hole. The sealing ring itself has elasticity, and the sealing ring is clamped by the first clamping ring and the first clamping groove, and the second clamping ring and the second clamping groove, so that the sealing ring is tightly closed with the bottom plate, thereby preventing rainwater from penetrating between the sealing ring and the bottom plate.

[0004] However, the existing W-shaped buckle is easily damaged after use and cannot be used multiple times. In addition, the waterproof effect of the W-shaped buckle is not good, and the surrounding plastic parts are damaged when the W-shaped buckle is pulled out of the sheet metal. SUMMARY

[0009] In order to improve the stability of the W-shaped buckle when subjected to force, the center line of the joint is collinear with the center line of the connecting column.

[0010] Preferably, the base is elliptical.

[0011] In order to reduce the influence of the W-shaped buckle on the plastic part, the root of the clamping block is connected with the base, and the outer surface of the root of the clamping block is provided with a sliding-out part, and the shape of the sliding-out part is a quarter of a conical body with the top point facing the base.

[0012] In order to improve the smoothness of the clamping head inserted into the metal plate, the upward outer surface of the root of the clamping block is provided with an insertion part, and the shape of the insertion part is a quarter of a conical body with the bottom surface facing the base.

[0013] In order to improve the stability of the W-shaped buckle fixed to the plastic part, the sliding-out part is connected with the insertion part, and a protrusion is formed at the connecting position.

[0014] In order to improve the waterproof effect of the W-shaped buckle, the outer surface of the waterproof ring is attached to the base, and the inner wall of the waterproof ring is attached to the root of the clamping block.

[0015] In order to improve the strength of the W-shaped buckle, the base plate, the base, the connecting column and the clamping head are an integral structure which cannot be separated, one end of the connecting column is fixedly connected with the base plate, the other end is fixedly connected with the base, and the materials of the base plate, the base, the connecting column and the clamping head are continuous and have no mechanical connection interface.

[0022] The technical solutions in the present application will be described clearly and completely below with reference to the drawings. Obviously, the described embodiments are only some of the embodiments of the present application, but not all. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work fall within the scope of protection of the present application.

[0023] Combination Figures 1-3 As shown in the figure, a W-shaped buckle for connecting an automobile exterior part and sheet metal includes a base plate 1, characterized in that: both sides of the base plate 1 are provided with notches 10, the top surface of the base plate 1 is connected with one end of a connecting column 11, the other end of the connecting column 11 is provided with a base 2, the upper part of the base 2 is connected with a sealing ring 3, and the upper part of the base 2 is provided with a car connector 4, the car connector 4 is composed of two car connector blocks 5, the inside of the base 2 is installed with a waterproof ring 6, and the waterproof ring 6 wraps the root of the car connector 4.

[0024] Among them, the shape of the base plate 1 is rectangular.

[0025] Among them, the center line of the car connector 4 is collinear with the center line of the connecting column 11.

[0026] Among them, the base 2 is elliptical.

[0027] Among them, the root of the car connector block 5 is connected with the base 2, and the outer surface of the root of the car connector block 5 is provided with a sliding part 7, and the shape of the sliding part 7 is a quarter of a conical body with the top point towards the base 2.

[0028] Among them, the upward outer surface of the root of the car connector block 5 is provided with an insert part 8, and the shape of the insert part 8 is a quarter of a conical body with the bottom surface towards the base 2.

[0029] Among them, the sliding part 7 is connected with the insert part 8, and a bump 9 is formed at the joint.

[0030] Among them, the outer surface of the waterproof ring 6 is attached to the base 2, and the inner wall of the waterproof ring 6 is attached to the root of the car connector block 5.

[0031] Among them, the base plate 1, the base 2, the connecting column 11 and the car connector 4 are an integral structure that cannot be separated, one end of the connecting column 11 is fixedly connected with the base plate 1, the other end is fixedly connected with the base 2, and the materials of the base plate 1, the base 2, the connecting column 11 and the car connector 4 are continuous and have no mechanical connection interface.

[0032] When installing the W-shaped buckle, the convenient insertion of the clamping head 4 into the metal sheet is realized by arranging the insertion part 8 on the outer surface of the clamping block 5. In addition, the convex block 9 structure formed by the combination of the sliding-out part 7 and the insertion part 8 ensures that after the clamping head 4 is inserted into the metal sheet, the plastic part can be stably fixed between the convex block 9 and the sealing ring 3, thereby improving the stability during the fixing of the plastic part.

[0033] During the pulling-out process of the W-shaped buckle, the conventional W-shaped buckle usually needs to exert a force of 300N to 400N, and is easy to cause damage to the surrounding plastic parts. In contrast, the W-shaped buckle designed by the present application, because the sliding-out part 7 is additionally arranged on the surface of the clamping block 5, the sliding-out part 7 will slide in close contact with the metal during the pulling-out process of the W-shaped buckle, so that only a force of 200N to 250N needs to be exerted to smoothly pull out the clamping head 4, and the surrounding plastic parts will not be damaged. At the same time, the base plate 1, the base 2, the connecting column 11 and the clamping head 4 are in an integrated structure, which enhances the strength of the W-shaped buckle as a whole, ensures that the W-shaped buckle will not be damaged after being pulled out, thereby realizing the reusability.

[0034] By installing the waterproof ring 6 inside the base 2, when water leakage occurs, the waterproof ring 6 cooperates with the sealing ring to prevent water flow, thereby significantly improving the waterproof performance of the W-shaped buckle in actual application.

[0035] The above disclosure is only a preferred embodiment of the present application, and of course cannot limit the scope of the rights of the present application. Those skilled in the art can understand that the implementation of all or part of the above-mentioned processes, and the equivalent changes made according to the claims of the present application, still belong to the scope covered by the present application.
