[0026] In order to help those skilled in the art better understand the present invention, the following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts should fall within the scope of protection of the present invention.

[0027] As described in the background, traditional automotive fasteners, such as bolts and nuts, can meet basic fastening requirements when connecting vehicle components. However, their water resistance often proves insufficient in the face of complex and changing environmental factors. In particular, in common situations like rain, car wash spray, and road water, moisture can penetrate through the tiny gaps between bolts and components, corroding the fasteners themselves and the connected components, thereby affecting the overall performance and safety of the vehicle.

[0028] In order to solve this technical problem, the utility model provides a waterproof sealing fastener.

[0029] Specifically, please refer to Figure 1-Figure 3 , waterproof sealing fasteners specifically include:

[0030] The fastening bolt 1 is provided with a waterproof sealing mechanism 2 on the outer surface of the fastening bolt 1. The waterproof sealing mechanism 2 includes a protective cover 201 sleeved on the outer surface of the fastening bolt 1. A protective cover 202 is provided on one side of the protective cover 201. A connecting shaft 203 is connected between the protective cover 202 and the protective cover 201.

[0031] The waterproof sealing fastener provided by the present invention, through the provision of a waterproof sealing mechanism 2, the protective cover 201 and the protective cover 202 can fit tightly between the bolt head and the corresponding components to form an effective waterproof barrier, effectively preventing moisture penetration and protecting the fastening bolt 1 and the connecting components from corrosion.

[0032] In order to enable those skilled in the art to better understand the solution of the present invention, the technical solution in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0033] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features and technical solutions therein can be combined with each other.

[0034] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0035] Example 1, please refer to Figure 1-Figure 3 A waterproof sealing fastener includes a fastening bolt 1, and a waterproof sealing mechanism 2 is provided on the outer surface of the fastening bolt 1. The waterproof sealing mechanism 2 includes a protective cover 201 sleeved on the outer surface of the fastening bolt 1, and a protective cover 202 is provided on one side of the protective cover 201. A connecting shaft 203 is connected between the protective cover 202 and the protective cover 201. Through the waterproof sealing mechanism 2 set in this application, the protective cover 201 and the protective cover 202 can fit tightly between the bolt head and the corresponding components to form an effective waterproof barrier, effectively preventing moisture penetration and protecting the fastening bolt 1 and the connecting components from corrosion.

[0036] Further, such as Figure 1-Figure 3 As shown, the side of the protective cover 201 away from the protective cover 202 is connected with a fixing glue 209, and the fixing glue 209 is used for the installation of the protective cover 201. When the fastening bolt 1 is connected to the corresponding component, the protective cover 201 can be installed on the corresponding component through the fixing glue 209, so that a sealed chamber can be formed between the fixing glue 209, the protective cover 201, the protective cover 202 and the corresponding component to reduce the corrosion of the external environment on the connection between the head of the fastening bolt 1 and the corresponding component.

[0037] Further, such as Figure 1 and Figure 3 As shown, a slot 204 is provided on one side of the protective cover 201 away from the connecting shaft 203, and the slot 204 is protruded on the side close to the protective cover 202. A claw 205 is provided on the protective cover 202 to engage with the protruding part of the slot 204. By engaging the protruding part of the slot 204 with the claw 205, the connection between the protective cover 202 and the protective cover 201 can be limited, thereby improving the stability of the connection between the protective cover 202 and the protective cover 201. The claw 205 is moved to separate the claw 205 from the protruding part of the slot 204, and the protective cover 202 can be rotated to open the protective cover 202.

[0038] Example 2 further optimizes the waterproof sealing fastener provided in Example 1. Specifically, Figure 2 and Figure 4As shown, a groove 206 is provided on one side of the protective cover 202 close to the protective hood 201 , and the position of the groove 206 is close to the position of the claw 205 . The opening of the groove 206 provides a deformation space for the claw 205 to bend.

[0039] Further, such as Figure 4 As shown, an elastic protective pad 207 is fixedly installed in the groove 206 . The elastic protective pad 207 is made of elastic rubber. The arrangement of the elastic protective pad 207 can seal the groove 206 .

[0040] Further, such as Figure 1 As shown, an elastic protective sheet 208 is fixedly connected between the side of the protective cover 201 away from the card slot 204 and the protective cover 202. The provision of the elastic protective sheet 208 can further seal the connection between the protective cover 201 and the protective cover 202.

[0041] Example 3 further optimizes the waterproof sealing fastener provided in Example 1 or 2. Specifically, Figure 3 and Figure 4 As shown, a drying portion is provided on the inner wall of the protective cover 202 , and the drying portion is used to achieve drying between the protective cover 202 and the protective cover 201 , thereby reducing the corrosion of the fastening bolts 1 by water vapor between the protective cover 201 and the protective cover 202 .

[0042] Further, such as Figure 3 and Figure 4 As shown, the drying part includes a threaded ring 3 fixedly mounted on the inner wall of the protective cover 202, and the inner wall of the threaded ring 3 is threadedly connected to a threaded barrel 301, and a bagged desiccant is placed in the threaded barrel 301. Rotating the threaded barrel 301 can realize the connection and separation of the threaded barrel 301 and the threaded ring 3, so as to facilitate the replacement of the bagged desiccant.

[0043] Further, such as Figure 4 As shown, a second opening 305 is provided on one side of the threaded barrel 301 away from the protective cover 202 . The second opening 305 is used to connect the inside and outside of the threaded barrel 301 , that is, the bagged desiccant in the threaded barrel 301 can absorb the moisture between the protective cover 201 and the protective cover 202 through the second opening 305 .

[0044] Further, such as Figure 4 As shown, a hand screw 302 is provided on the side of the threaded barrel 301 away from the protective cover 202, and a baffle 303 is provided on the outer surface of the hand screw 302. A first opening 304 is provided on the baffle 303. After loosening the hand screw 302, the baffle 303 is rotated so that the first opening 304 and the second opening 305 are staggered, thereby sealing the second opening 305. In this way, the bagged desiccant can be prevented from absorbing external moisture before the protective cover 202 is opened.
