[0025] This utility model provides, for example Figures 1-4 The sealing type seahorse rivet shown includes a rivet 1 and a rivet shell 2. The rivet shell 2 includes an annular rim 201, an enlarged section 202 and a deformable section 203. The annular rim 201, the enlarged section 202 and the deformable section 203 are integrally formed, and the enlarged section 202 is located between the annular rim 201 and the deformable section 203.

[0026] Among them, the outer diameter of the annular rim 201 is larger than the outer diameter of the enlarged section 202 and the deformed section 203. The outer diameters of the enlarged section 202 and the deformed section 203 are the same, and the inner diameter of the enlarged section 202 is smaller than the inner diameter of the deformed section 203. In actual use, the inner diameter of the workpiece hole to which the seahorse rivet is used is smaller than the outer diameter of the annular rim 201, but larger than the outer diameters of the enlarged section 202 and the deformed section 203, so that the enlarged section 202 and the deformed section 203 can pass into the workpiece hole. The enlarged section 202 is located inside the workpiece hole.

[0027] The nail rod 1 includes a docking section 101, which is used to dock with the rivet gun. One end of the docking section 101 located inside the nail shell 2 has an integrally formed extrusion section 103. The extrusion section 103 is distributed correspondingly to the deformation section 203. The outer diameter of the extrusion section 103 is larger than the inner diameter of the expansion section 202. When the docking section 101 is pulled, the extrusion section 103 is squeezed into the expansion section 202, which will cause the expansion section 202 to expand and become larger.

[0028] The end of the extrusion section 103 away from the docking section 101 is provided with a contraction section 104 and a nail head section 105 in sequence. The outer diameter of the contraction section 104 is smaller than the outer diameter of the extrusion section 103. The outer diameter of the nail head section 105 is the same as the outer diameter of the deformation section 203. The inner diameter of the deformation section 203 at the corresponding position of the contraction section 104 is smaller than the inner diameter of other positions of the deformation section 203, forming a limiting fit so that the nail rod 1 and the nail shell 2 will not separate, making it easy to use.

[0029] In addition, the material hardness of the nail head section 105 is greater than that of the material hardness of the deformation section 203 and other locations, which facilitates the deformation of the deformation section 203 and other locations.

[0030] The nail shell 2 is fitted with a sealing sleeve 3. The sealing sleeve 3 is distributed correspondingly to the expansion section 202. The sealing sleeve 3 can be made of rubber, but is not limited to rubber. The sealing sleeve 3 and the nail shell 2 are assembled together for easy selective use. The outer diameter of the sealing sleeve 3 at the annular eave 201 is larger than the outer diameter at other positions. The larger outer diameter is attached to the outer wall of the workpiece.

[0031] Specifically, the sealing sleeve 3 is fitted onto the outside of the nail shell 2, corresponding to the position of the expansion section 202. Then, the expansion section 202 and the deformation section 203 are inserted into the workpiece hole. The expansion section 202 and the sealing sleeve 3 are located inside the workpiece hole. Then, the rivet gun is used to grab the mating section 101 and pull the mating section 101 outward. During the process of the rivet gun grabbing the mating section 101 and pulling the nail head section 105, the nail head section 105 compresses the deformation section 203 and deforms, expanding outward and opening, cooperating with the annular rim 201 to clamp and fix the workpiece.

[0032] At the same time, the extrusion section 103 extrudes into the expansion section 202, causing the expansion section 202 to expand and become larger. The sealing sleeve 3 is tightly attached to the inner wall of the workpiece hole, achieving the function of waterproof sealing. Due to the extrusion of the expansion section 202, the sealing sleeve 3 will not slide at will, improving the stability of use.

[0033] This utility model, by setting up a compression section 103, an expansion section 202 and a sealing sleeve 3, has a waterproof sealing function, and the sealing sleeve 3 will not slide at will, thus improving the efficiency of the sealed seahorse rivet.

[0034] To prevent the sealing sleeve 3 from slipping randomly, an outer ring 205 is integrally formed on the outer wall of the expansion section 202. When the sealing sleeve 3 is fitted onto the outside of the nail shell 2, the outer ring 205 can increase the friction between the sealing sleeve 3 and the outer wall of the nail shell 2, thus preventing the sealing sleeve 3 from slipping randomly when the expansion section 202 and the deformation section 203 are inserted into the workpiece hole.

[0035] Furthermore, even after the expansion section 202 expands and becomes larger, the outer ring 205 can still increase the friction between the sealing sleeve 3 and the outer wall of the nail shell 2, ensuring the stability of the sealing sleeve 3 in use.

[0036] The deformation section 203 is provided with a through groove 204. Multiple through grooves 204 are provided and are evenly distributed around the deformation section 203. The through grooves 204 are provided to facilitate the deformation section 203 to expand and open outward evenly after deformation, ensuring the efficiency of cooperation with the annular eaves 201 and improving the stability of workpiece clamping and fixing.

[0037] A fracture section 102 is provided on the docking section 101. The fracture section 102 is located at one end of the docking section 101 near the extrusion section 103. After the rivet is fixed, the docking section 101 breaks at the fracture section 102.

[0038] The mating section 101 is provided with annular grooves 4, which are located outside the nail shell 2. Multiple annular grooves 4 are provided and are evenly distributed. The depth of the annular grooves 4 is appropriate and will not affect the strength of the mating section 101. The annular grooves 4 are used in conjunction with the rivet gun to increase the friction between the nail rod 1 and the riveting machine, thereby improving the extraction effect of the nail rod 1.

[0039] The end of the mating section 101 away from the nail shell 2 is provided with a rounded corner 5, which makes it easy for the mating section 101 to be inserted into the rivet gun.

[0040] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the principles of the present utility model should be included within the protection scope of the present utility model.
