[0017] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0018] See also Figures 1 to 3 The utility model provides a technical solution: a buckle, comprising a pillar 1, a pressure plate 2 arranged at one end of the pillar 1, a connecting column 12 connected to the pressure plate 2, and a card plate 3 arranged at one end of the connecting column 12, characterized in that: a sealing gasket 4 is sleeved on the outer side of the pillar 1, and the sealing gasket 4 is used to seal between the pressure plate 2 and the automobile body, thereby meeting the sealing requirements of waterproof and dustproof, a convex ring 10 is provided on one side of the sealing gasket 4, and a groove 9 matched with the convex ring 10 is provided on the side of the pressure plate 2 close to the sealing gasket 4. The fit between the convex ring 10 and the groove 9 can increase the contact area between the sealing gasket 4 and the pressure plate 2, thereby improving the sealing between the sealing gasket 4 and the pressure plate 2, and an extension portion 5 is provided on the side of the sealing gasket 4 away from the convex ring 10. The extension portion 5 is used to increase the contact area between the sealing gasket 4 and the installation hole, thereby improving the sealing of the sealing gasket 4, and a chamfer 6 is provided at the bottom of the extension portion 5, and the chamfer 6 is used to guide the extension portion 5, so that the extension portion 5 can enter the installation hole more easily.

[0019] A through hole 11 is formed in the middle of the sealing gasket 4 , and the through hole 11 is convenient for the sealing gasket 4 to be sleeved on the outside of the pillar 1 .

[0020] The cross-sections of the through hole 11 and the pillar 1 are both square, and the square shape prevents the pillar 1 from rotating due to the vibration generated when the car is running after installation, thereby ensuring that the pillar 1 is firmly installed and that the sealing gasket 4 can provide good sealing performance.

[0021] Among them, the sealing gasket 4, the extension part 5 and the convex ring 10 are all made of foam. The foam has good elasticity and compressibility, so that the sealing performance is excellent. It also has excellent waterproof and dustproof capabilities and can effectively prevent the intrusion of moisture and dust.

[0022] The bottom of the support 1 is provided with a contraction portion 8, and the contraction portion 8 makes it easier for the support 1 to be aligned with the installation hole and inserted.

[0023] Elastic sheets 7 are symmetrically arranged on the outer side of the pillar 1 , and the elastic sheets 7 are used to engage with the mounting holes on the vehicle body, so as to fix the pillar 1 on the vehicle body.

[0024] The pillar 1, the pressure plate 2, the connecting column 12 and the clamping plate 3 are an integrated structure, which is convenient for production, reduces production costs, and can improve structural strength.

[0025] Specifically, when in use, the clamping plate 3 and the connecting column 12 are engaged with the automobile decorative part, and then the pillar 1 is aligned with the installation hole on the automobile body and inserted, and the extension part 5 will enter the installation hole and fit with the installation hole. Under the action of the elastic sheet 7, the pillar 1 is fixed on the automobile body, thereby fixing the automobile decorative part on the automobile body. When the pillar 1 is installed in place, the pressure plate 2 and the automobile body will also compress the sealing gasket 4, thereby further improving the sealing effect of the sealing gasket 4 to meet the sealing requirements of waterproof and dustproof.
