Description

Technical Field

[0001] The utility model relates to the technical field of mechanical connection, in particular to a bolt with a shockproof function. Background Art

[0002] Mechanical connection is a method of connecting two or more parts together through fasteners. This method usually requires the use of fasteners such as bolts, nuts, screws, etc. The material of these parts is usually metal, but other materials such as plastic and rubber can also be used. In the process of mechanical connection, bolts are often required for connection.

[0003] After searching, the patent number is CN212744643U, and the name is a bolt with anti-vibration and anti-loosening functions, including an external hexagonal fixing column and a shock-absorbing pad device. Through research and analysis, it is found that although there is the advantage of magnetic stable connection, there are still the following disadvantages to a certain extent.

[0004] For example, during use, the bolts mentioned above usually do not have multiple composite contact sealing pads at the contact position between the bolts and other mechanical objects, and usually do not have a secondary buffer fixing mechanism at the bottom, which can easily affect the shockproof stability of the main body. In order to solve the above technical problems, we have designed a bolt with shockproof function. Utility Model Content

[0005] The utility model aims to provide a bolt with a shockproof function, which has the advantage of a shockproof buffering effect and solves the problem of poor buffering effect and relatively general overall connection stability.

[0006] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: a bolt with shockproof function, comprising a bolt body, a hexagonal top piece welded on the top of the bolt body, a secondary fixing mechanism arranged at the bottom of the bolt body, the secondary fixing mechanism comprising a rubber positioning block, the top of the rubber positioning block is pasted to the bolt body, a first contact buffer pad is pasted to the bottom of the hexagonal top piece, the first contact buffer pad comprises an outer gasket layer, and a connecting nut is arranged on the surface threaded sleeve of the bolt body.

[0007] Preferably, a second contact buffer pad is adhered to the top and the bottom of the connecting nut, and anti-slip grooves are provided on the surface of the connecting nut.

[0008] Preferably, an elastic buffer sleeve is provided on the surface of the rubber positioning block, and a positioning slot is provided on the top of the elastic buffer sleeve.

[0009] Preferably, a hexagonal screw hole is provided on the top of the external hexagonal top piece, a first buffer layer is pasted on the top of the external gasket layer, and a second buffer layer is pasted on the top of the first buffer layer.

[0010] Preferably, an inner gasket layer is adhered to the top of the second buffer layer, and the inner gasket layer is specifically made of titanium alloy material.

[0011] Preferably, the first buffer layer is made of nitrile rubber material, the second buffer layer is made of silicone rubber material, and the outer gasket layer is made of IXPP foam material.

[0012] Compared with the prior art, the beneficial effects of the utility model are as follows:

[0013] The utility model can improve the buffering effect of the first contact buffer pad during use by arranging the second contact buffer pad outer gasket layer and the first buffer layer and the second buffer layer inner gasket layer. If the bolt body is installed on both sides, the user can ensure the buffering effect of the contact position by arranging an elastic buffer sleeve on the surface damping sleeve of the rubber positioning block, thereby improving the shockproof performance of the entire bolt body after installation.
