Embodiment Construction

[0006] The present invention is achieved in that three anti-bolts 1 are made of 1. screw rod, 2. plug sleeve, 3. nut three parts. It is characterized in that the plug sleeve ② is pressed into the tight round hole ⑤ in the center of the screw ① and the nut ③ through the inner tight plug ④, and fits with the screw ① and nut ③ to form a fastening assembly structure; the disassembly tool 2 is composed of ⑥ Fork jaw sleeve, ⑦ movable sleeve, ⑧ handle sleeve, ⑨ setback bolt. It is characterized in that the fork claw sleeve ⑥ passes through the inner arc surface of the fork claw ⑩ part and the outer arc surface of the round platform of the plug sleeve ② on the three-proof bolt 1 is tight, and the pipe thread on the outer circle is connected with the movable sleeve ⑦The internal circle standard thread system in ⑦ cooperates, and then realizes the rotation through the inner sleeve hole structure of the handle sleeve ⑧ and the movable sleeve ⑦, and pulls out the plug sleeve ② through th...

Abstract

A three-defenses bolt and its demolition tool belong to the invention of mechanical assembly and fastening piece technology field. The purpose of the invention is: providing a anti-theft and anti-release and anti-trust nut and bolt components and its special demolition tool, reaching the goal of anti-theft and anti-release through friction wedge way and the goal of anti-rust through the sealing way and the goal of demolition through special demolition tool, thereby it fills the gap of prior technology. The invention includes: 1. three-defenses bolt and 2, demolition tool, among then the three-defenses bolt 1 consists of 1 bolt, 2 choke plug sleeve and 3 nut. The demolition tool 2 consists of 6 fork sleeve, active sleeve 7, 8 handle sleeve and 9 sleeve-back bolt. The three-defenses bolt 1 can be used for fastening workpieces and plays role of anti-theft and anti-release and anti-trust; the demolition tool 2 is used for demounting three-defenses bolt 1, at the same time it also can be combined with electric instrument as general demount instrument. The invention applies to the fasten assemblage of prior mechanical equipment, particularly it is suitable for the special bolts of rail track, aerospace craft and future space station.

Description

technical field [0001] A three-proof bolt and a dismantling tool belong to the invention in the technical field of mechanical assembly and fasteners. Background technique [0002] Most of the anti-loosening and anti-theft bolts involved in the prior art have complex structures, many components and inconvenient processing. And it does not have the antirust function to the threaded part. And the anti-rust bolt does not possess anti-theft. This is the drawback of the prior art. Contents of the invention [0003] The purpose of the present invention is to provide an anti-theft, anti-loosing and anti-rust bolt member and a special disassembly tool, which solves the purpose of anti-theft and anti-loosening by friction and tightness, solves the purpose of anti-rust by sealing, and achieves disassembly by special disassembly tools. purpose, thereby filling the gaps in the prior art. [0004] The present invention comprises: 1, three anti-bolts, 2, dismounting tool two parts. ...
