Description

Technical Field

[0001] The utility model relates to a vertical tooth sealed single drum rivet, belonging to the technical field of rivets. Background Art

[0002] Some door panels of containers, vans, and refrigerated trucks require riveting with single-drum rivets to achieve higher connection strength. At the same time, due to the special use of containers, vans, refrigerated trucks and other equipment, there are also high requirements for the sealing and waterproofness of the connection parts. Ordinary single-drum rivets cannot meet these requirements at all. Often, due to the poor sealing of the connection parts, external water or other liquids can easily penetrate into the interior of the box, causing damage to the internal goods and causing huge losses to users. Utility Model Content

[0003] In view of the above deficiencies in the prior art, the technical problem to be solved by the present invention is: to provide a vertical tooth sealed single drum rivet with good sealing and waterproof properties, which can avoid damage to goods due to poor sealing of the connection parts.

[0004] The vertical tooth sealed single-drum rivet described in the utility model includes a nail core and a nail shell. The nail core is arranged through the nail shell. The nail core is provided with a nail head, a nail core vertebral body, a vertical tooth sealing section, a fracture, an assembly section, a nail core coupling section, and a friction wire from top to bottom. The nail core vertebral body is connected to the upper part of the nail shell. The vertical tooth sealing section is provided with vertical teeth evenly arranged along the circumferential direction. The outer diameter of the vertical tooth sealing section is larger than the outer diameters of the assembly section and the nail core coupling section. The vertical tooth sealing section is coated with sealant, which is added before the nail core and the nail shell are assembled to increase the sealing of the rivet after riveting.

[0005] The technical solution of the utility model is to provide a vertical tooth sealed single drum rivet, in which vertical teeth evenly arranged along the circumferential direction are provided in the vertical tooth sealing section of the nail core. Before the nail core and the nail shell are assembled, sealant is applied to the vertical tooth sealing section to increase the sealing after riveting and achieve a completely waterproof effect.

[0006] Preferably, a through stepped hole is provided in the center of the nail shell, and a section with a smaller inner diameter on the stepped hole is a sealing area.

[0007] Furthermore, the nail shell is provided with an arc-shaped eaves, and a protrusion is provided on the arc-shaped eaves near the outer side. After riveting, the protrusion can press the connecting parts to improve the connection strength between the nail shell and the parts; an avoidance groove is provided on the inner side of the protrusion on the arc-shaped eaves, and the avoidance groove is used to avoid burrs on the edge of the rivet hole, so that the rivet can fit tightly with the part.

[0008] Preferably, the outer diameter of the vertical tooth sealing section of the rivet core is larger than the inner diameter of the sealing area of ​​the rivet shell. When the rivet core is pulled down by the rivet gun, the vertical tooth sealing section is pulled into the sealing area of ​​the rivet shell to achieve riveting. After the rivet is riveted, the vertical tooth sealing section forms an interference fit with the sealing area, and under the action of the sealant, the center of the rivet is sealed to achieve a waterproof seal.

[0009] Preferably, the assembly section is provided with vertical teeth evenly arranged along the circumferential direction, which are used to assemble the nail core and the nail shell together to play an assembly role; the friction wire can increase the friction force and better cooperate with the rivet gun to complete the riveting construction.

[0010] Compared with the prior art, the present invention has the following beneficial effects:

[0011] The vertical tooth sealed single drum rivet described in the utility model is provided with vertical teeth on the vertical tooth sealing section of the nail core. Before the nail core and the nail shell are assembled, sealant is applied to the vertical tooth sealing section to increase the sealing after riveting. The utility model has good sealing and waterproof properties, and can avoid damage to goods due to poor sealing of the connection parts. BRIEF DESCRIPTION OF THE DRAWINGS
