Problems solved by technology

[0002] At present, in all kinds of mechanical equipment, bolts are mostly used as fastening parts for the tight connection of equipment. However, there are certain shortcomings in the use of bolt fastening, that is, during equipment maintenance, due to long-term use, there are many bolts that are tightly connected to them. The solid nuts will be locked due to rust. To remove the rust and loosen the bolts, some use a bolt loosening agent to spray the bolt connection. The loosening effect of this loosening agent is not ideal, because the loosening agent can only be sprayed At the interface between the nut and the bolt, the spraying area is small, and it is not easy to loosen the bolt quickly

Embodiment Construction

[0009] The present invention will be described in further detail below in conjunction with the accompanying drawings.

[0010] see figure 1 , 2 , a kind of anti-rust bolt, comprising a bolt body 1, one end of the bolt body 1 is provided with a connecting thread 2, at least one oil outlet hole 3 is arranged in the groove of the connecting thread 2, and the oil outlet hole 3 is connected with the bolt body 1 The inner and axially arranged oil injection holes 4 communicate with each other, and the oil inlet of the oil injection hole 4 is arranged at the top end 5 of the bolt.

[0011] The working principle of the present invention is:

[0012] When in use, inject the bolt loosening agent or lubricating oil into the oil filling hole 4 along the oil inlet under a certain pressure, and make the bolt loosening agent or lubricating oil enter the connecting thread 2 along the oil filling hole 4 through the oil outlet hole 3, and the connecting thread 2. Derust and loosen the fasteni...

Abstract

Provided is an antirust bolt. The antirust bolt comprises a bolt body. A connecting thread is arranged in one end of the bolt body, and at least one oil outlet is arranged in a groove of the connecting thread and communicated with an oil filling hole which is arranged in the bolt body and disposed along the axial direction. An oil inlet of the oil filling hole is arranged in the bolt top end, and bolt loosen fluid or lubricant is filled into the oil filling hole along the oil inlet under certain pressure and enters into the connecting thread along the oil filling hole through the oil outlet so as to remove rust and loose the connecting thread and a clamp nut. The antirust bolt has the advantages of being simple in structure, convenient to maintain and good in antirust effect.

Description

technical field [0001] The invention belongs to the technical field of bolt maintenance, and in particular relates to an anti-rust dead bolt. Background technique [0002] At present, in all kinds of mechanical equipment, bolts are mostly used as fastening parts for the tight connection of equipment. However, there are also certain shortcomings in the use of bolt fastening. That is, when equipment is maintained, due to long-term use, there are many bolts that are tightly connected to it. The solid nuts will be locked due to rust. To remove the rust and loosen the bolts, some use a bolt loosening agent to spray the bolt connection. The loosening effect of this loosening agent is not ideal, because the loosening agent can only be sprayed At the interface between the nut and the bolt, the spraying area is small, and it is not easy to loosen the bolt quickly. Contents of the invention [0003] In order to overcome the above-mentioned deficiencies in the prior art, the object ...
