[0002] Currently, automotive sealing buckles are important components in automobile manufacturing and are widely used in the connection and sealing of various parts of the car body. Although traditional automotive sealing buckles can meet basic sealing requirements, they still need to be improved in terms of installation convenience, sealing effect and durability.

[0003] For example, a car buckle is disclosed in the Chinese utility model patent publication number (CN209492485U), which includes a buckle seat and a buckle core. The buckle seat has a cylindrical body, and the outer peripheral surface of the body has a positioning structure for positioning the buckle seat. The top of the body has a circular convex edge folded outward, and a sealing gasket is arranged on the convex edge; the inside of the body has a cylindrical connecting part, and the buckle core has a clamping joint that can be inserted into the connecting part. The clamping joint is clamped and positioned with the connecting part through a clamping structure, and the bottom of the connecting part is closed. This utility model solves the problem that plastic buckles or mother-and-child buckles do not have sealing and waterproof functions, and the sealing of the connection is poor. However, the existing automobile sealing buckles usually adopt a single buckle structure and are installed by a simple clamping method. This installation method is often difficult to ensure the firmness of the buckle and the durability of the sealing effect. After long-term use, the sealing performance is easily reduced due to factors such as vibration and aging, and even falls off, affecting the overall sealing effect and safety of the car.

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.

[0029] See also Figure 1-2 In this embodiment, an automobile sealing buckle includes a buckle body 1, an elastic clamp arm 2 is fixed to the right side of the buckle body 1, and an anti-drop mechanism 3 for enhancing the buckle firmness is provided on the elastic clamp arm 2, thereby improving the firmness and durability of the buckle and improving the overall safety and service life of the automobile. A sealing gasket 4 is fixed to the left side of the buckle body 1, so that the automobile sheet metal can maintain excellent sealing performance for a long time.

[0030] In this embodiment, the buckle body 1 is in a Z-shape, and the sealing gasket 4 is inclined to the left, so as to match the shape of the automobile sheet metal and facilitate the insertion of the buckle into the mounting hole of the automobile sheet metal.

[0031] It should be noted that the length of the sealing gasket 4 is greater than the length of the buckle body 1, and the width of the sealing gasket 4 is greater than the width of the buckle body 1, so that after the buckle body 1 is inserted into the mounting hole of the automobile sheet metal part, the sealing gasket 4 can completely seal the mounting hole.

[0032] See also Figure 3-4 In order to improve the firmness and durability of the buckle and enhance the overall safety and service life of the automobile, the anti-slip mechanism 3 in this embodiment includes a clamping block 31, a locking member 32, and two anti-slip members 33. The clamping block 31 is fixed to the lower surface of the elastic clamping arm 2. The locking member 32 is arranged on the clamping block 31, and is used to lock the elastic clamping arm 2 inside the automobile sheet metal, so that the buckle is difficult to be removed from the inside of the mounting hole. The two anti-slip members 33 are both arranged on the elastic clamping arm 2 and are symmetrically distributed about the central axis of the clamping block 31, and are used to prevent the elastic clamping arm 2 from falling off from the automobile sheet metal, further enhancing the firmness of the buckle and preventing it from falling off due to vibration and other reasons.

[0033] In this embodiment, the locking member 32 includes a first spring piece 321 and a second spring piece 322. A first mounting opening 323 is provided on the front of the card block 31. The first spring piece 321 is fixed to the inner top wall of the first mounting opening 323. A second mounting opening 324 is provided on the front of the card block 31. The second spring piece 322 is fixed to the inner bottom wall of the second mounting opening 324. The card block 31 drives the first spring piece 321 and the second spring piece 322 to move. The mounting hole squeezes the first spring piece 321 and the second spring piece 322. When the elastic card arm 2 moves to the innermost part of the mounting hole, the first spring piece 321 and The elastic force of the second spring piece 322 acts on the inner wall of the mounting hole to lock the position of the elastic clamping arm 2. The anti-slip component 33 includes a connecting block 331, a third spring piece 332, and a hook 333. The connecting block 331 is fixed to the lower surface of the elastic clamping arm 2, the third spring piece 332 is fixed to the lower surface of the connecting block 331, and the hook 333 is fixed to the front of the third spring piece 332. The elastic clamping arm 2 drives the connecting block 331 to move to the corresponding position, the third spring piece 332 pops out the hook 333, and the hook 333 hooks inside the mounting hole to enhance the firmness of the buckle and prevent the buckle from falling off.

[0034] It should be noted that the first mounting port 323 is located above the second mounting port 324, the first spring piece 321 and the second spring piece 322 have the same inclination direction, so that the buckle body 1 can be locked inside the mounting hole, the inclination direction of the third spring piece 332 is opposite to the inclination direction of the first spring piece 321, and the inclination direction of the barb 333 is opposite to the inclination direction of the third spring piece 332, so that the barb 333 can be hooked inside the mounting hole to improve firmness.

[0035] The working principle of the above embodiment is:

[0036] (1) First, apply special sealant to the side where the sealing gasket 4 is connected to the buckle body 1, and then insert the elastic clamp arm 2 into the mounting hole of the automobile sheet metal, and apply appropriate pressure to make the elastic clamp arm 2 elastically deform and clamp into the inside of the mounting hole. After the elastic clamp arm 2 enters the mounting hole, the elastic clamp arm 2 drives the clamp block 31 to move, and the clamp block 31 drives the first spring sheet 321 and the second spring sheet 322 to move. The mounting hole squeezes the first spring sheet 321 and the second spring sheet 322. When the elastic clamp arm 2 moves to the innermost part of the mounting hole, the elastic force of the first spring sheet 321 and the second spring sheet 322 acts on the inner wall of the mounting hole, so that the position of the elastic clamp arm 2 is locked.

[0037] (2) At the same time, the elastic clamp arm 2 drives the connecting block 331 to move to the corresponding position, and the third spring piece 332 pops out the hook 333, and the hook 333 is hooked inside the mounting hole. Since the elastic force direction of the first spring piece 321 and the second spring piece 322 is the same, the elastic force direction of the third spring piece 332 is opposite to the elastic force direction of the first spring piece 321, so the firmness of the buckle body 1 can be improved in both the front and rear directions, and the firmness of the buckle can be further enhanced to prevent it from falling off due to vibration and other reasons. When the elastic clamp arm 2 enters the innermost part of the mounting hole, the sealing gasket 4 is in contact with the automobile sheet metal at this time, and the sealing gasket 4 cooperates with the special sealant to seal the mounting hole to form an effective seal.
