Abstract
Description
Technical Field
[0001] The utility model relates to a raised sealing type single drum rivet, belonging to the technical field of rivets. Background Art
[0002] A rivet is a mechanical component used to connect two or more objects. Typically consisting of a core and a shell, a rivet is inserted into a pre-drilled hole in the objects being connected. Force is then applied to one end of the core, causing the shell to deform and securely fasten the objects together. Rivets are widely used to connect components made of various materials. However, in the automotive, aerospace, and electronic equipment manufacturing industries, high standards are placed on waterproofing, dustproofing, and sealing performance of connected components. Conventional rivets often fail to maintain a good seal after installation, leading to component damage and severely impacting the product's lifespan. Utility Model Content

[0005] The technical solution of the utility model is to provide a raised sealing single-drum rivet, which seals the gap between the nail shell and the connecting piece by arranging a rubber gasket on the nail shell; when riveting, the bulge on the nail shell is squeezed by a rivet gun so that it is embedded in the groove sealing section, thereby sealing the gap between the nail shell and the nail core, achieving good waterproof, dustproof and sealing properties.
[0006] Preferably, an assembly section is provided below the nail head, and the assembly section is provided with a plurality of teeth, and the nail core and the nail shell are assembled together through the teeth to prevent the nail core from falling out of the nail shell.
[0007] Preferably, a through stepped hole is provided in the center of the nail shell.
[0008] Furthermore, an avoidance groove is provided on the inner side of the brim of the nail shell, and the avoidance groove provides a movable space for the rubber gasket to avoid burrs on the edge of the rivet hole, so that the rivet can fit tightly with the connecting piece.
[0009] Preferably, the friction wire is located below the rivet gun coupling section to increase friction 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 raised sealing single-drum rivet described in the utility model seals the gap between the nail shell and the connecting piece by arranging a rubber gasket on the nail shell; during riveting, the protrusion on the nail shell is squeezed by a rivet gun to deform it and embed it into the groove sealing section, thereby sealing the gap between the nail shell and the nail core; after installation, the utility model has good waterproof, dustproof and sealing properties, and can effectively avoid the situation where the service life of the product is affected by poor sealing of the connection part.

[0017] The present invention will be further described below with reference to specific embodiments.
[0018] However, the description of the present invention is merely an embodiment of structural and even functional description, and the scope of rights of the present invention is not limited by the embodiments described herein.
[0019] For example, multiple embodiments may have various modifications and various forms, and it should be understood that the scope of rights of the present invention includes equivalents that can implement the technical idea.
[0020] like Figure 1-4As shown, this embodiment is implemented by the following technical solutions: it includes a nail core 1 and a nail shell 2, the nail core 1 is arranged through the nail shell 2, and the nail core 1 is provided with a nail head 11, a groove sealing section 13, a fracture 14, a rivet gun coupling section 15, and a friction wire 16; the diameter of the groove sealing section 13 is smaller than the diameter of other adjacent parts; the nail shell 2 is provided with a brim, and the upper part of the brim is provided with a rubber gasket 23 for sealing the gap between the nail shell 2 and the connecting piece; a protrusion 22 is provided at the bottom of the brim of the nail shell 2. After riveting, the protrusion 22 is embedded in the groove sealing section 13 under the extrusion of the rivet gun to seal the gap between the nail shell 2 and the nail core 1.
[0021] In this embodiment, an assembly section 12 is provided below the nail head 11. The assembly section 12 is provided with multiple teeth. The nail core 1 and the nail shell 2 are assembled together through the teeth to prevent the nail core 1 from falling out of the nail shell 2. A stepped hole is provided through the center of the nail shell 2. An avoidance groove 21 is provided on the inner side of the brim of the nail shell 2. The avoidance groove 21 provides a movable space for the rubber gasket 23 to avoid burrs on the edge of the rivet hole, so that the rivet can fit tightly with the connecting piece. The friction wire 16 is located below the rivet gun coupling section 15 to increase friction and better cooperate with the rivet gun to complete the riveting construction.
[0022] The method of using the utility model is as follows:

[0024] 2. Connect the rivet gun to the rivet gun coupling section 15 on the nail core, and then use the rivet gun to pull the nail core 1. The nail core 1 continuously applies pressure to the nail shell 2, so that the nail shell 2 forms a single drum expansion area, and the connector A3 and the connector B4 are gradually clamped and connected;
[0025] 3. Continue to pull the nail core 1 until the nail shell 2 can no longer be deformed, the force on the fracture 14 increases sharply, the fracture 14 breaks, and the riveting is completed;
[0026] At this time, the rubber gasket 23 seals the gap between the nail shell 2 and the connecting piece B4 under the extrusion of the two; the protrusion 22 on the nail shell is deformed under the extrusion of the rivet gun and embedded in the groove sealing section 13, sealing the gap between the nail shell 2 and the nail core 1, achieving good waterproof, dustproof and sealing properties.
