Waterproof connecting piece of riveting system and riveting system

Abstract

The invention relates to a waterproof connecting piece of a riveting system and the riveting system. The waterproof connecting piece of the riveting system comprises a main body, and a base connectedto one end of the main body; a first extrusion part and a second extrusion part are arranged on the outer side surface of the main body in the axial direction of the main body; and a waterproof part is arranged on the outer side of the second extrusion part. The device is provided with the waterproof part; workpieces butt against the waterproof part; the main body is extruded by hand external force for deformation after installation; the contacted parts of the workpieces with the waterproof part are covered through the waterproof part, so that the waterproof function is effectively achieved, and meanwhile, the locking function of the main body is guaranteed; the waterproof part is arranged on the main body; and an additional waterproof piece is not needed, so that the installation precision can be guaranteed, and meanwhile, the longer service life can be achieved.

Description

technical field [0001] The invention relates to a blind rivet nut, in particular to a waterproof connector of a riveting system. Background technique [0002] Some waterproof connectors may have waterproof problems. For example, the blind rivet nuts commonly used in blind riveting connections cannot be applied to equipment requiring waterproofing due to lack of waterproof function. [0003] Blind rivet nuts are mainly fixed parts that can be quickly installed on one side of the product by using the size of the existing holes; Quantification, thereby reducing the weight of the body to achieve better energy-saving and environmental protection effects. [0004] At present, most aluminum alloy car bodies adopt the structure of aluminum alloy profile skeleton combined with skin, and the connection methods of aluminum alloy profiles are mainly welding and riveting. Compared with welding, riveting has the characteristics of simple process, low cost of equipment and fixtures, and...

Problems solved by technology

[0006] Therefore, blind rivet nuts have been widely used. However, at present, many fields have put forward waterproof requirements for blind rivet connections. For example, in the new energy automobile industry, when using existing blind rivet nuts for connection, even if the connection Stability, but because the blind rivet nut is not waterproof, water will seep into the device with the blind rivet nut, affecting the use

[0007] In the prior art, a rivet nut with waterproof function is also designed, for example, the Chinese patent number is CN201320742061.6, and the name is: a waterproof rivet nut. The disclosed waterproof rivet nut includes rivet nut 1 and Waterproof layer 2; the rivet nut 1 is provided with a base 4; the internal test in the anti-layer is provided with a double-sided adhesive 3; the waterproof layer 2 is pasted on the base 4 of the rivet nut 1 through the double-sided adhesive 3 Above; although the blind rivet nut in this technology has a waterproof function, it is only realized by double-sided adhesive tape, and the waterproof effect is not good. It will gradually reduce its waterproof performance after being soaked in water for a long time. At the same time, the double-sided adhesive tape is set on the base , affecting the locking effect;
