Description

Technical Field

[0001] The utility model belongs to the technical field of rivets and relates to a capped seahorse rivet. Background Art

[0002] A rivet is a nail-shaped object used to connect two parts (or components) with a through hole and a cap at one end. Riveting utilizes deformation or interference fit to connect the parts being riveted. While standard seahorse rivets are designed to prevent loosening and theft, they lack waterproof sealing properties.

[0003] The existing Chinese utility model patent with announcement number CN216044879U, the sealed seahorse rivet includes a nail rod and a nail shell, the nail shell is inserted into the nail rod, the nail rod and the nail shell are a rotating body, the nail rod is divided into five sections, and a nail head section, a locking section, a sealing section, a disconnecting section and a nail rod body are arranged in sequence from one end to the other end. The nail head section is provided with a nail head, the outer diameter of the nail head section is greater than the outer diameter of the sealing section, the outer diameter of the sealing section is greater than the outer diameter of the nail rod body, and a sealing column is provided on the sealing section; a first cylinder and a second cylinder are provided on the nail shell, an annular eaves is provided on the outer side of the first cylinder, the inner diameter of the second cylinder is greater than the inner diameter of the first cylinder, and the nail shell can be stamped and fitted on the locking section.

[0004] The existing technology has the following technical defects:

[0005] Although the above technical solution can achieve sealing inside the nail shell, there is no sealing measure at both ends of the nail shell. One end is completely exposed, and the other end will also have a gap due to deformation. Therefore, although sealing is achieved inside the nail shell, water or other corrosive substances can still enter both ends, causing rust or corrosion fracture. Utility Model Content

[0006] The technical problem to be solved by the utility model is to overcome the deficiencies of the prior art and provide a capped seahorse rivet.

[0007] The capped seahorse rivet described in the utility model comprises a rivet shell and a rivet core. The rivet core is provided with a rivet head, vertical teeth, a fracture, a rivet gun coupling section and a friction wire from top to bottom. A groove is provided at the connection between the rivet head and the rivet core, and a sealing protrusion corresponding to the groove is provided on the rivet shell; and a cap cover is also included that is adapted to the through hole at the bottom of the rivet shell.

[0008] Working process or working principle:

[0009] When in use, the rivet is passed through two holes of the parts so that the bottom of the nail shell is against the parts, and then it is tightened and deformed to fix it through a rivet gun. When tightened and deformed, the sealing protrusion of the nail shell and the groove on the nail core are still in contact with each other, and the vertical teeth penetrate into the inner wall of the nail shell under the action of tension to achieve sealing and fixation. When the rivet gun is pulled off, the through hole at the bottom of the nail shell is blocked and sealed by covering the cap to complete the connection of the parts.

[0010] The nail shell is divided into a sealing connection section and a rivet disconnection section, and the inner diameter of the sealing connection section is larger than the inner diameter of the rivet disconnection section.

[0011] The diameter of the nail head is larger than the outer diameter of the top of the nail shell.

[0012] The diameter of the vertical teeth is larger than the inner diameter of the sealing connection section in the nail shell.

[0013] The bottom of the nail shell is provided with an avoidance groove at the edge of the rivet hole of the part.

[0014] The diameter of the rivet gun coupling section is smaller than the inner diameter of the sealing connection section.

[0015] Compared with the prior art, the beneficial effects of the present invention are:

[0016] The utility model provides a groove between the nail core and the nail head and presses the corresponding position of the nail shell tightly so that the nail shell still has a sealing effect after deformation. At the same time, a cap is added. When the rivet is broken, the cap is buckled and pressed on the open end of the nail shell so that the open through hole is also blocked and covered, thereby further protecting the sealing part of the nail shell from being invaded, rusted or corroded.

[0022] Example 1

[0023] like Figures 1 to 4As shown, the capped seahorse rivet described in the present invention includes a nail shell 5 and a nail core 3. The nail core 3 is provided with a nail head 1, a vertical tooth 4, a fracture 9, a rivet gun coupling section 7 and a friction wire 8 in sequence from top to bottom. A groove 2 is provided at the connection between the nail head 1 and the nail core 3, and a sealing protrusion 10 corresponding to the groove 2 is provided on the nail shell 5; it also includes a cap 6 adapted to the through hole at the bottom of the nail shell 5, and the through hole at one end of the sealing nail shell 5 can be blocked by the cap 6 to prevent water or other substances from entering and corroding the vertical teeth 4 and the inner wall of the nail shell 5; the nail shell 5 is divided into a sealed The sealing connection section 12 and the rivet disconnecting section 13, the inner diameter of the sealing connection section 12 is larger than the inner diameter of the rivet disconnecting section 13; the diameter of the nail head 1 is larger than the outer diameter of the top of the nail shell 5; the diameter of the vertical teeth 4 is larger than the inner diameter of the sealing connection section 12 in the nail shell 5; the bottom of the nail shell 5 is located at the edge of the rivet hole of the part and an avoidance groove 11 is provided. The avoidance groove 11 can avoid burrs on the edge of the rivet hole on the part, and can avoid burrs so that the nail shell 5 and the part fit closely; the diameter of the rivet gun coupling section 7 is smaller than the inner diameter of the sealing connection section 12.

[0024] Working process or working principle:

[0025] When in use, the rivet is passed through the two part holes so that the bottom of the nail shell 5 is against the part, and then it is tightened and deformed to fix it through a rivet gun. When tightened and deformed, the sealing protrusion 10 of the nail shell 5 is still in contact with the groove 2 on the nail core 3, and the vertical teeth 4 penetrate into the inner wall of the nail shell 5 under the action of tension to achieve sealing and fixation. When the rivet gun is pulled off, the cap 6 is covered on the through hole at the bottom of the nail shell 5 to block and seal, completing the connection of the parts.

[0026] The present invention provides a groove 2 between the nail core 3 and the nail head 1 and presses the corresponding position of the nail shell 5 tightly so that it can still achieve a sealing effect after deformation. At the same time, a cap 6 is added. When the rivet is broken, the cap 6 is buckled and pressed on the open end of the nail shell 5 so that the open through-hole is also blocked and covered, thereby further protecting the sealed part of the nail shell 5 from being invaded, rusted or corroded.

[0027] The description of the direction and relative position relationship of the structure in the present invention, such as the description of front, back, left, right, up and down, does not constitute a limitation of the present invention and is only for the convenience of description.
