Embodiment Construction

[0109] The present invention will be described in further detail below in conjunction with the accompanying drawings and specific embodiments.

[0110] Such as Figure 1-21 As shown, tighten the deformed locking bolt, which consists of special-shaped bolt 1, cap nut 2, rectangular kit 3, and gasket 4. One end of the special-shaped bolt 1 is the head 11, the other end is the fixed rod 13, and the middle is the outer The threaded screw rod 12 has a nut 21, a cover body 22, and a fixing hole 23 on the cap nut 2, and a gasket 4 is arranged between the special-shaped bolt 1 and the cap nut 2 to separate each other; the cap body 22 and the nut 21 on the cap nut 2 Connected as a whole, the inner top surface 221 of the cover body 22 has a fixing hole 23, and the inner height of the cap nut 2 is greater than the length of the fixing rod 13. When the fixing rod 13 passes through the nut 21 to the fixing hole on the inner top surface 221 of the cover body 22 23, the screw rod 12 on the ...

Abstract

The invention discloses a tightening deformation locking bolt. The tightening deformation locking bolt is composed of a special-shaped bolt, a cap nut, a rectangular sleeve part and a spacer, wherein one end of the special-shaped bolt is a head portion; the other end of the special-shaped bolt is a fixing rod; the middle of the special-shaped bolt is a screw rod with outer threads; the cap nut is provided with a nut body, a cap and a fixing hole; the special-shaped bolt and the cap nut are spaced by the spacer; the cap and the nut body on the cap nut are connected together; the fixing hole is formed in the inner top face of the cap; the internal height of the cap nut is greater than the length of the fixing rod; when the fixing rod penetrates through the nut body to the fixing hole in the inner top face of the cap, the screw rod on the special-shaped bolt is combined with the nut body on the cap nut, and the locking effect is achieved through rotating; the shape of the special-shaped bolt and the cap nut can be mechanically machined and manufactured, so that the production cost is relatively low, and large-scale production can be achieved. The tightening deformation locking bolt has good market prospects.

Description

technical field [0001] The invention relates to tightening deformation locking bolts. Background technique [0002] There are many types of anti-loosening bolts on the market. The most commonly used one is to use spring washers to achieve anti-loosening effect, but the effect is average. There is also an anaerobic adhesive applied to the screw, which works well, but it is not resistant to high temperatures and has a certain shelf life. Now there is a nylon ring in combination with the nut, which realizes the purpose of locking the screw rod in use. There is also a method of mechanical destruction, and the screw rod of the bolt is bent to prevent loosening, but there will be a problem that it is difficult to remove. There are also some that are anti-loose through the design of the structural angle of the gear, and there are also openings such as grooves that are anti-loose. The latest one is to add a ring of gears to the nut or gasket to achieve extrusion deformation, ther...
