[0030] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all the embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present utility model.

[0031] Refer to Figure 1 - Figure 3 , an embodiment provided by the present utility model: A buckle for fixing an automotive sealing strip includes a limiting disk 2, which is an integral structure with a plurality of clamping flaps 3 and is used to cooperate with the connection between the clamping flaps 3 and the vehicle body. A clamping post 1 is movably connected to the middle of the limiting disk 2. A plurality of clamping flaps 3 are fixedly connected to the lower part of the limiting disk 2 and are used to be fixed to the vehicle body mounting holes. The plurality of clamping flaps 3 are inclined, and the plurality of clamping flaps 3 can form a shape similar to a cone with a wider upper part and a narrower lower part. The clamping flaps 3 are thinner at the top and thicker at the bottom to facilitate their deformation and inward contraction. The top of the clamping post 1 is fixedly connected with a clamping head 4. The clamping post 1 and the clamping head 4 are integrally designed and are used to connect with the sealing strip. The front and rear parts of the clamping head 4 are slightly narrower than the middle part to facilitate the clamping head 4 to be inserted into the mounting opening on the sealing strip.

[0032] Furthermore, a round head 11 is fixedly connected to the lower part of the clamping column 1, which is convenient for connecting with the clamping flap 3 and for clamping into the clamping groove 35, thereby stretching open multiple clamping flaps 3, so that the clamping flap 3 is more tightly connected to the vehicle body mounting port and is not easy to fall off. A clamping ring 12 is fixedly connected to the upper part of the outer wall of the clamping column 1, which is used to cooperate with the connection between the clamping column 1 and the limiting disk 2. It is an arc-shaped ring body, and the middle part of the clamping ring 12 is hollow, and an opening is provided at the lower part to facilitate the deformation of the clamping ring 12, so that the clamping ring 12 can pass through the bayonet 21 to fix the clamping column 1 and the limiting disk 2. A bayonet 21 is provided in the middle part of the limiting disk 2 for cooperating with the connection of the clamping ring 12, and the clamping ring 12 is movably connected thereto.

[0033] like Figure 4 As shown, the upper part of the outer wall of the card flap 3 is fixedly connected with a convex strip 31, and its outer surface is arc-shaped, which can form a shape similar to a circular ring. The diameter of the vehicle body mounting hole is slightly smaller than the diameter of the circular ring formed by multiple convex strips 31. The lower part of the outer wall of the card flap 3 is provided with an arc guide surface 34 to facilitate the insertion of the card flap 3 into the vehicle body mounting hole. The lower part of the outer wall of the card flap 3 is fixedly connected with a first clamping platform 32, and the middle part of the card flap 3 is fixedly connected with a second clamping platform 33, which is used to cooperate with the connection between the card flap 3 and the vehicle body mounting hole to cooperate with the limiting of the buckle position. The multiple clamping platforms can form a shape similar to an inverted frustum. When the card flap 3 is contracted, its diameter is slightly smaller than the circular ring formed by the convex strips 31 to facilitate the removal of the mounting hole. The lower part of the inner wall of the card flap 3 is provided with a clamping groove 35 for cooperating with the connection of the round head 11, which can limit the round head 11 to a certain extent, and the round head 11 is movably connected with it.

[0034] Working principle: When in use, first align the limit plate 2 together with the card flap 3 connected thereto with the mounting hole on the vehicle body, and then press the multiple card flaps 3 into the mounting hole of the vehicle body. When the card flap 3 is pressed into the mounting hole of the vehicle body, since the mounting hole is slightly smaller than the circular ring formed by the multiple convex strips 31, when the convex strips 31 are pressed into the mounting hole, the mounting hole will squeeze the multiple convex strips 31 inward. At this time, the multiple card flaps 3 will shrink inward to facilitate the card flap 3 to be inserted into the mounting hole. After the card flap 3 is pressed into the mounting hole, the card flap 3 loses the pressure applied by the mounting hole The plurality of card flaps 3 are initially fixed to the mounting holes, and then the clamp head 4 on the clamp column 1 is inserted into the mounting hole on the sealing strip, so that the sealing strip and the clamp column 1 are connected through the clamp head 4, and then the clamp column 1 passes through the bayonet 21 and is pressed between the plurality of card flaps 3. Due to the pushing of the clamp column 1, the plurality of card flaps 3 will be stretched open. When the clamp ring 12 is pressed against the bayonet 21, since its interior is hollow, when it is subjected to the pressure exerted by the bayonet 21, it will be deformed, making it easier to pass through the bayonet 21. After passing through the bayonet 21, it loses its The force applied by the bayonet 21 will cause the clamping ring 12 to recover and be clamped on the side of the limit plate 2 away from the clamping head 4, so that the clamping column 1 is fixed to the limit plate 2 and the clamping flap 3. At this time, the round head 11 will be clamped into the clamping groove 35 to fully open the multiple clamping flaps 3. When the clamping flaps 3 are opened, the clamping column 1 inside the multiple clamping flaps 3 can no longer shrink inward, so that the clamping flaps 3 and the vehicle mounting hole are completely fixed, thereby preventing the buckle from falling off the vehicle body. When the buckle needs to be removed, the clamping head 4 is first separated from the sealing strip. Then, the clamping column 1 is pulled by the clamping head 4 to drive the clamping ring 12 to disengage from the limiting plate 2. The clamping ring 12 will be deformed again under the action of the clamping mouth 21 until it is disengaged from the clamping mouth 21. Then, the clamping column 1 is completely pulled out of the limiting plate 2 so that the multiple clamping petals 3 can shrink inward again. Then, the limiting plate 2 is pulled to drive the multiple clamping petals 3 to move out of the installation port. Since the outer surface of the convex strip 31 is arc-shaped, it is easier to disengage from the installation port. Then, by pulling the limiting plate 2, the multiple clamping petals 3 can be taken out of the installation port.

[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
