Description

Technical Field

[0001] This invention relates to the field of snap fastener technology, and more particularly to a combination snap fastener with waterproof function. Background Technology

[0002] During the installation of interior and exterior automotive parts, clips are used to secure different components. There are many types of clips available, which can be mainly divided into two categories based on whether they are waterproof: waterproof clips and non-waterproof clips. Waterproof clips are generally installed on sheet metal that requires waterproofing, such as the sheet metal locations where car door sills, license plate plates, and other parts are installed, to prevent the sheet metal from rusting due to water entering the mounting holes.

[0003] While existing metal buckles offer good resistance to deformation and wear, their limited manufacturing process and hollow structure generally prevent them from achieving a waterproof seal. In contrast, two-color injection-molded plastic buckles can achieve waterproofing, but their manufacturing process is complex, production costs are high, and their installation with interior and exterior plastic panels is also complicated.

[0027] The present invention will be further described and illustrated below with reference to specific embodiments and the accompanying drawings:

[0028] Example 1

[0029] Please refer to Figure 1 and Figure 2A waterproof combination buckle includes a rubber sleeve 10 for fixing to automotive interior and exterior plastic trim, a buckle female seat 20, a buckle male seat 30, and a plastic rib 40. The rubber sleeve 10 is fitted onto the surface of the buckle female seat 20. The buckle female seat 20 includes a female seat platform 21 and a female seat body 22. The female seat platform 21 extends outward along the upper edge of the female seat body 22. The buckle male seat 30 includes a male seat platform 31 and a male seat body 32. The male seat platform 31 extends outward along the upper edge of the male seat body 32. The male seat body 32 is inserted into the female seat body 22 and is buckled to the female seat body 22. The male seat platform 31 is located above the female seat platform 21. One end of the plastic rib 40 is inserted into the male seat body 32 for fixing. The upper end of the plastic rib 40 covers the male seat platform 31 and also covers the female seat body 22.

[0030] Please refer to Figure 2 and Figure 3 In use, first, the rubber sleeve 10 is placed on the surface of the snap-fit ​​female seat 20 to wrap the snap-fit ​​female seat 20, making the snap-fit ​​female seat 20 waterproof. Then, the snap-fit ​​female seat 20 is installed on the corresponding component. The plastic rib 40 is fixedly connected to the plastic panels of the car's interior and exterior trim. The plastic rib 40 is inserted into the male seat body 32 for fixation, and the upper end of the plastic rib 40 is placed on the male seat platform 31. Then, the male seat body 32 together with the plastic rib 40 is inserted into... In the female body 22, the male body 32 is snapped together with the female body 22, so that the upper end of the plastic rib 40 covers the female body 22 and is used to close the opening where the female body 22 is inserted into the male body 32. After the female body 22 and the male body 32 are snapped together, they form a sealed structure. The snap-fit ​​female body 20 and snap-fit ​​male body 30 can achieve better resistance to deformation and wear resistance, while the rubber sleeve 10 and the plastic rib 40 serve the purposes of waterproofing, corrosion resistance and ease of manufacturing.

[0031] In order to fix the plastic reinforcing bar 40 to the male seat body 32, a male seat barb 321 is provided inside the male seat body 32. The male seat barb 321 is inclined downward towards the center of the male seat body 32. When the plastic reinforcing bar 40 is inserted into the male seat body 32, the oppositely provided male seat barb 321 clamps and fixes the plastic reinforcing bar 40.

[0032] In the above scheme, the edge of the female platform 21 is provided with a number of female hooks 211 at intervals, the upper end of the rubber sleeve 10 is provided with a rubber sleeve platform 11, the edge of the rubber sleeve platform 11 is provided with a number of holes 111 at intervals, and the holes 111 are alternately inserted with the female hooks 211 so that the holes 111 and the female hooks 211 are interference fit.

[0033] Please refer to Figure 4When the rubber sleeve 10 is assembled with the snap-fit ​​female seat 20, since the rubber sleeve 10 is made of soft rubber, the rubber sleeve 10 will be stretched open by the expansion of the snap-fit ​​female seat 20. After the female seat platform 21 and the rubber sleeve platform 11 are attached, the lower end of the female seat body 22 is also attached to the bottom of the inner wall of the rubber sleeve 10, and the female seat hook 211 is inserted into the hole 111 to prevent the rubber sleeve 10 from detaching from the snap-fit ​​female seat 20.

[0034] Please refer to Figure 5 and Figure 6 The female seat body 22 has female seat shoulders 222 on both sides, and two female seat shoulders 222 are provided opposite each other on the same side of the female seat body 22. The upper and lower ends of the female seat shoulders 222 are sloped towards the female seat body 22. The male seat body 32 has outward protruding male seat shoulders 322 on both sides. The upper and lower ends of the male seat shoulders 322 are sloped towards the male seat body 32. The male seat shoulders 322 are respectively inserted between the two female seat shoulders 222 on the same side, thereby using the female seat shoulders 222 to laterally block the male seat shoulders 322, thereby preventing lateral swinging when the male seat body 32 is inserted into the female seat body 22.

[0035] Furthermore, a concave spring piece 223 is provided between the two female shoulder parts 222 on the same side of the female body 22. The concave spring piece 223 protrudes towards the inner side of the female body 22. The male body 32 is provided with a groove 323 corresponding to the concave spring piece 223. The groove 323 is located at the lower end of the male shoulder 322. The concave spring piece 223 and the groove 323 are snapped together.

[0036] When the male seat body 32 is inserted into the female seat body 22, the groove 323 on the male seat body 32 corresponds to the concave spring piece 223 of the female seat body 22, so that the concave spring piece 223 is engaged in the groove 323 for a snap-fit ​​connection, thereby fixing the male seat body 32 inside the female seat body 22 and achieving vertical fixation.

[0037] It also includes a sheet metal part 50, the surface of which is provided with a locking hole 51, and the upper end of the shoulder 222 of the female part is provided with a stop surface 224, which has a V-shaped structure. The female part 20 and the rubber sleeve 10 are inserted into the locking hole 51, and the female part 20 is engaged with the sheet metal part 50 through the stop surface 224.

[0038] Sheet metal part 50 can be a fixed component for assembly on a car. Therefore, the snap-fit ​​female seat 20 can be snapped to the car parts. After the rubber sleeve 10 is placed on the surface of the snap-fit ​​female seat 20, the snap-fit ​​female seat 20 and the rubber sleeve 10 are inserted into the locking hole 51, so that the inner wall of the locking hole 51 is locked at the stop surface 224 of the female seat shoulder 222, thereby fixing the snap-fit ​​female seat 20 to the sheet metal part 50. Since both ends of the female seat shoulder 222 are sloped towards the female seat body 22, it is also convenient to insert the female seat body 22 into the locking hole 51 along the shoulder. It is also convenient for people to pull the female seat out of the locking hole 51. Similarly, the male seat shoulder 322 of the male seat body 32 also plays the above role.

[0039] The lower surface of the rubber sleeve platform 11 is provided with a skirt 112, which is attached to the upper surface of the sheet metal and has a raised step structure or an umbrella-shaped structure. After the sheet metal part 50 is fixed to the snap-fit ​​female seat 20, the skirt 112 is pressed and attached to the upper surface of the sheet metal part 50. Since the skirt 112 on the rubber sleeve platform 11 is made of soft rubber, it can seal the upper surface of the sheet metal part 50 and prevent water leakage.

[0040] Example 2

[0041] Please refer to Figure 7 and Figure 8 The inner wall of the female body 22 is provided with female barbs 221. The female barbs 221 are inclined downward towards the center of the female body 22. When the overall cost is reduced or the strength requirement is not high, the plastic rib 40 can be directly inserted into the female body 22. The female barbs 221 of the female body 22 are used to clamp and fix the plastic rib 40, and the plastic rib 40 acts as the male buckle 30. The original male buckle 30 is not needed, which reduces the cost. However, when the male buckle 30 is used in conjunction with the female buckle 20, the female barbs 221 in the female body 22 are not provided.

[0042] Furthermore, when using Embodiment 2, since the female body 22 does not need to be snapped together with the male body 32, the female body 22 does not need to be provided with a concave spring piece 223.

[0043] Example 3

[0044] Please refer to Figure 9 , Figure 10 and Figure 11Another structural method involves a snap-fit ​​connection between the female seat body 22 and the male seat body 32. The inner wall of the female seat body 22 is provided with a female seat rib 225, which protrudes towards the inner side of the female seat body 22. The female seat ribs 225 are paired to form a snap-fit ​​structure. The male seat body 32 is provided with a male seat spring 323 corresponding to the female seat rib 225. The male seat spring 323 is located at the lower end of the male seat body 32. The female seat rib 225 and the male seat spring 323 are snap-fit ​​connected.

[0045] When the male seat body 32 is inserted into the female seat body 22, the male seat spring 323 on the male seat body 32 aligns with the female seat rib 225 on the female seat body 22, causing the male seat spring 323 to snap into the slot formed by the female seat rib 225 to form a snap connection, thereby fixing the male seat body 32 inside the female seat body 22 and achieving vertical fixation.

[0046] This invention provides a waterproof combination buckle. In use, a rubber sleeve is first placed on the surface of the buckle female seat to wrap the buckle female seat and make it waterproof. Then, the buckle female seat is installed on the corresponding component. The plastic rib is fixedly connected to the plastic panel of the car's interior and exterior trim. The plastic rib is inserted into the male seat body for fixation, and the upper end of the plastic rib covers the male seat platform. Then, the male seat body and the plastic rib are inserted into the female seat body. The male seat body and the female seat body are snapped together, and the upper end of the plastic rib covers the top of the female seat body to close the opening where the female seat body is inserted into the male seat body. After the female seat body and the male seat body are snapped together, they form a sealed structure. The buckle female seat and the buckle male seat provide good resistance to deformation and wear, while the rubber sleeve and the plastic rib provide waterproofing, corrosion resistance, and ease of manufacturing.

[0047] Finally, it should be noted that the above embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of the present invention without departing from the essence and scope of the technical solutions of the present invention.
