[0002] Fasteners are a type of mechanical part used for fastening connections and are widely used. They are characterized by a wide variety of types and specifications, different performance and uses, and a high degree of standardization, serialization and generalization. Fasteners are the most widely used basic mechanical components. Among them, there are many types of waterproof fasteners, of which waterproof lantern rivets are one.

[0004] Therefore, it is necessary to provide a waterproof fastener with a sealing structure to solve the above-mentioned technical problems. Utility Model Content

[0005] This utility model provides a waterproof fastener with a sealing structure, which solves the problem that current waterproof lantern rivets use a sealing gasket for sealing and fixing by pulling and expanding during use. However, the sealing gasket used on current lantern rivets is prone to deformation when squeezed, which leads to a decrease in sealing performance after long-term use.

[0006] To solve the above-mentioned technical problems, this utility model provides a waterproof fastener with a sealing structure, comprising:

[0007] Metal cover, rivet body, threaded rod, gasket and sealing assembly;

The mounting sleeve is connected to one end of the rubber sealing cover, and the rubber sealing cover is fitted onto the surface of the threaded rod through the mounting sleeve.

[0011] Preferably, the limiting bolt is disposed between the mounting sleeve and the threaded rod.

[0012] Preferably, the plurality of limiting holes are respectively formed on the surface of the threaded rod.

[0013] Preferably, the sealing gasket is used for the initial sealing of the metal cover.

[0014] Preferably, the rubber sealing cover is used for secondary sealing of the metal cover.

[0015] Preferably, one end of the threaded rod is provided with a splicing assembly, the splicing assembly including a threaded connecting rod and a splicing block, the threaded connecting rod being connected to the threaded rod through the splicing block.

[0016] Preferably, the splicing block is used for the breakage operation of the threaded connecting rod.

[0017] Compared with related technologies, the waterproof fastener with a sealing structure provided by this utility model has the following beneficial effects:

[0018] This utility model provides a waterproof fastener with a sealing structure. By setting a rubber sealing cover, mounting sleeve, limit bolt and multiple limit holes between the metal cover and the threaded rod, together with the sealing gasket, it can provide a double sealing effect for the entire device when the threaded rod and the rivet body are fixed, thereby preventing the sealing performance from decreasing after long-term use.

[0026] The present invention will be further described below with reference to the accompanying drawings and embodiments. Example

[0027] Please refer to the following: Figure 1 , Figure 2 , Figure 3 and Figure 4 ,in, Figure 1 A schematic diagram of the structure of a first embodiment of a waterproof fastener with a sealing structure provided by this utility model; Figure 2 for Figure 1 The enlarged schematic diagram of part A shown below; Figure 3 for Figure 1 A three-dimensional structural diagram of the waterproof fastener shown; Figure 4 for Figure 3 The enlarged schematic diagram of part B shown. A waterproof fastener with a sealing structure includes:

[0028] 1. Metal cover; 2. Rivet body; 3. Threaded rod; 5. Sealing gasket; and 4. Sealing assembly.

[0029] The rivet body 2 is disposed inside the metal cover 1, and the threaded rod 3 is disposed between the rivet body 2 and the metal cover 1;

[0030] The sealing gasket 5 is disposed inside the metal cover 1;

[0031] The sealing assembly 4 is disposed on the surface of the metal cover 1. The sealing assembly 4 includes a rubber sealing cover 41, a mounting sleeve 42, a limiting bolt 43 and a plurality of limiting holes 44. The mounting sleeve 42 is connected to one end of the rubber sealing cover 41, and the rubber sealing cover 41 is sleeved on the surface of the threaded rod 3 through the mounting sleeve 42.

[0032] The use of the mounting sleeve 42 facilitates the connection between the rubber sealing cover 41 and the threaded rod 3 and the metal cover 1. The use of the limiting bolt 43 and the limiting hole 44 facilitates the fixing of the rubber sealing cover 41 with the mounting sleeve 42 to the metal cover 1 and the threaded rod 3. A through hole is opened at the center of the surface of the sealing gasket 5 to facilitate the installation between the metal cover 1 and the rivet body 2.

[0033] The limiting bolt 43 is disposed between the mounting sleeve 42 and the threaded rod 1.

[0035] The sealing gasket 5 is used for the initial sealing of the metal cover 1.

[0036] The rubber sealing cover 41 is used for secondary sealing of the metal cover 1.

[0037] The working principle of the waterproof fastener with a sealing structure provided by this utility model is as follows:

[0038] In use, when the metal cover 1 with the rivet body 2 is installed on the object, the tool is used to pull the rivet body 2 upward to cooperate with the metal cover 1 to expand. After the rivet body 2 and the metal cover 1 are expanded and fixed, the sealing gasket 5 is squeezed and sealed. After the entire device is installed, the rubber sealing cover 41 of the mounting sleeve 42 is put on the surface of the metal cover 1 and the threaded rod 3. At the same time, after the bottom of the rubber sealing cover 41 contacts and adheres to the object, the limiting bolt 43 is connected by passing through the limiting hole 44 between the mounting sleeve 42 and the threaded rod 3.

[0039] Compared with related technologies, the waterproof fastener with a sealing structure provided by this utility model has the following beneficial effects:
