Waterproof and breathable heat dissipation multifunctional bolt

Abstract

The invention discloses a waterproof and breathable heat dissipation multifunctional bolt. The multifunctional bolt comprises a bolt head. The bolt head comprises a bolt head body and a bolt head outer cap. The bolt head outer cap is arranged on the outer portion of the bolt head body. A waterproof and breathable layer is arranged between the bolt head body and the bolt head outer cap. When the waterproof and breathable heat dissipation multifunctional bolt is used for fixing a deformable object with small thickness, a waterproof convex ring on the upper portion of a nut is inlaid in a waterproof ring groove at the lower end of the bolt head to prevent outside water from getting into the bolt, and the waterproof effect can be effectively achieved. Under the other condition, if the waterproof and breathable heat dissipation multifunctional bolt is used for fixing hard objects with certain thickness, the two objects are fixed between the bolt head and the nut, and a water baffle is pushed out under the action of elastic force of a spring, so that the lower end of the water baffle makes contact with the upper surface of the first clamped object to achieve the waterproof effect. Oblique through holes and vertical vent through holes communicating with the oblique through holes are formed in the bolt head and can achieve the ventilation and heat dissipation effects.

Description

technical field [0001] The invention relates to the technical field of fastening connectors, in particular to a waterproof, breathable and heat-dissipating multifunctional bolt. Background technique [0002] A bolt is a mechanical part, a cylindrical threaded fastener with a nut. A type of fastener consisting of a head and a screw, which needs to be matched with a nut to fasten two parts with through holes. This form of connection is called a bolt connection. If the nut is unscrewed from the bolt, the two parts can be separated, so the bolt connection is a detachable connection. Bolt, be indispensable in daily life and in the middle of commercial production manufacture, and bolt is also referred to as the rice of industry, and it can be seen that bolt is widely used, and the operation scope of bolt has: electronic product, mechanical product, digital product, power equipment , Mechanical and electrical machinery products, etc. [0003] Existing bolts do not have waterproo...

AI Technical Summary

Problems solved by technology

[0003] The existing bolts do not have waterproof and breathable functions, which affects the service life of the bolts on the one hand, and does not meet the waterproof requirements of some specific usage scenarios on the other hand.
