[0002] The vehicle buckle is commonly used for the installation of the vehicle body guard plate, has the technical effect of quick mounting and quick dismounting, replaceability and high economy, but most of the existing buckles are single in size and structure, and the buckles of specific sizes are customized for specific guard plates, the adaptability is weak, and if the size is slightly changed, the guard plate is directly loose, abnormal sound is produced, and even cannot be installed. SUMMARY

[0003] The utility model discloses a kind of vehicle guard plate mounting sub and mother buckles, which are strong in adaptability, adjustable in installation size, and firm in guard plate installation.

[0004] To achieve the above purpose, the utility model provides a kind of vehicle guard plate mounting sub and mother buckles, which include a sub and a mother buckle.

[0005] The insertion part of the mother buckle is spindle-shaped, with a thick waist and thin ends, and is hollow inside. One end of the insertion part is provided with a insertion hole, and a ring of pressing edge is arranged around the insertion hole. A stepped limiting platform is arranged between the waist of the insertion part and the pressing edge. An avoiding hole is arranged between the limiting platform and the inner wall of the insertion part.

[0006] The sub includes a insertion rod and a buckle cap, and the insertion rod is inserted into the mother buckle.

[0007] Further, both sides of the bottom of the insertion rod are provided with clamping feet, and the hollow part of the mother buckle is provided with a stop block matched with the clamping feet. The stop block prevents the sub from being pulled out, and the stop block is located below the waist of the insertion part.

[0008] Further, the inner wall of the hollow part of the mother buckle is further provided with two clamping grooves, and the two clamping grooves are matched with the two clamping feet of the sub for clamping to prevent the sub from being pulled out. The clamping grooves are arranged above the waist of the insertion part and close to the insertion hole.

[0009] Further, the surface of the pressing edge is provided with a ring of grooves, and when the sub is completely inserted into the mother buckle, the buckle cap of the sub is pressed in the grooves.

[0010] Further, the surface of the pressing edge is further provided with a notch for prying out the sub.

[0011] Compared with the prior art, the utility model has the advantages that:

[0012] 1. The female buckle of this utility model is designed with a stepped limiting platform on its outer periphery. The stepped limiting platform can provide installation conditions for various diameters, thereby adapting to the multi-diameter installation requirements of the guard plate and the body sheet metal. At the same time, there is an avoidance hole between the limiting platform and the inner wall of the insertion part, so that the limiting platform has a certain elastic space and forms an interference fit with the connection hole of the sheet metal or guard plate, ensuring the installation effect and preventing loosening.

[0013] 2. The insertion of the male buckle into the female buckle of this utility model effectively prevents the female buckle from shrinking and deforming, thereby preventing the female buckle from slipping out of the sheet metal connection hole and ensuring the connection effect.

[0018] To make the objectives, technical solutions, and advantages of this utility model clearer, the technical solutions of this utility model will be further described below.

[0019] like Figure 1 As shown, this utility model proposes a male and female fastener for mounting a vehicle skid plate, which consists of two parts: a male fastener 1 and a female fastener 2. The specific structure is as follows:

[0020] like Figure 2 As shown, the insertion part 21 of the female buckle 2 is spindle-shaped, thicker at the waist and thinner at both ends. A stepped limiting platform 23 is provided between the waist of the insertion part 21 and the pressing edge 22. The stepped limiting platform 23 can provide installation conditions for various diameters, thereby adapting to the multi-diameter installation requirements of the guard plate 3 and the body sheet metal 4. An avoidance hole 24 is provided between the limiting platform 23 and the inner wall of the insertion part 21. The avoidance hole 24 gives the limiting platform 23 a certain elastic space, forming an interference fit with the connecting hole of the sheet metal 4 or the guard plate 3, ensuring the installation effect and preventing loosening. The diameter of the waist is ensured to be larger than the hole diameter of the sheet metal 4 and the guard plate 3 to prevent the female buckle 2 from sliding out of the through hole of the sheet metal 4 or the guard plate 3.

[0021] In this embodiment, as Figure 2 As shown, the plug-in part 21 is hollow inside, and one end of the plug-in part 21 is provided with a plug hole. Figure 3As shown, the female buckle 1 consists of two parts: a plug rod 11 and a buckle cap 12. The plug rod 11 is inserted into the hollow part of the female buckle 2 through the plug hole to prevent the female buckle 2 from being compressed or deformed, and to slide out from the plug hole of the sheet metal 4 and the guard plate 3.

[0022] In this embodiment, a retaining ring 22 is provided around the circumference of the insertion hole on the female buckle 2; as shown Figure 4 As shown, when the female buckle 2 is inserted into the connection hole between the sheet metal 4 and the guard plate 3, the pressing edge 22 is pressed against the surface of the guard plate 3 to achieve fixation.

[0023] In this embodiment, to ensure the effective removal of the buckle 1, as follows: Figure 3 As shown, the bottom of the insertion rod 11 is provided with locking feet 13 on both sides, as... Figure 2 As shown, the inner wall of the hollow portion of the female buckle 2 is provided with two slots 25. The two slots 25 respectively engage with the two locking feet 13 of the male buckle 1 to prevent the male buckle 1 from being pulled out. The slots 25 are located above the waist of the insertion portion 21, close to the insertion hole. During the pre-installation stage, the locking feet 13 of the male buckle 1 are inserted and fixed in the slots 25 on both sides, realizing the following... Figure 1 The structure shown.

[0024] The hollow portion of the female buckle 2 is provided with a stop block 26 that engages with the locking foot 13. The stop block 26 prevents the female buckle 1 from being pulled out. The stop block 26 is located below the waist of the insertion portion 21; Figure 4 As shown, when the female buckle 2 is inserted into the through hole of the sheet metal 4 and the guard plate 3, press the end of the male buckle 1 to fully insert the male buckle 1 into the female buckle 2. At this time, the locking foot 13 of the male buckle 1 is located below the stop block 26, and the stop block 26 can effectively prevent the male buckle 1 from being pulled out.

[0025] In this embodiment, to ensure the aesthetics of the snap fastener, the pressing edge 22 of the female snap fastener 2 has a groove around its surface. When the male snap fastener 1 is fully inserted into the female snap fastener 2, the cap 12 of the male snap fastener 1 is pressed into the groove. At the same time, in order to enable the male snap fastener 1 to be pulled out, the pressing edge 22 also has a slot for prying out the male snap fastener 1.

[0026] The above are merely preferred embodiments of this utility model and do not constitute any limitation on this utility model. Any equivalent substitutions or modifications made by those skilled in the art to the technical solutions and contents disclosed in this utility model without departing from the scope of the technical solutions of this utility model shall still fall within the protection scope of this utility model.
