Description

Bolt anti-loosening assembly

(I) technical field

The invention relates to a bolt anti-loosening assembly.

(II) background of the invention

At present, the bolt anti-loosening method mainly realizes the anti-loosening of the bolt by adjusting structures such as the bolt and the nut, the process is complicated, and the problem of loosening of the bolt under working conditions such as vibration and the like cannot be completely avoided.

In view of the above-mentioned drawbacks, a bolt loosening prevention assembly has thus been invented.

Disclosure of the invention

The invention aims to provide a bolt anti-loosening assembly which can effectively avoid the rotation phenomenon of a bolt in the processes of vibration and the like on the basis of not changing the structure of the bolt, thereby realizing the anti-loosening of the bolt.

The technical scheme includes that the bolt anti-loosening assembly comprises a rack body, a limiting plate nut, a groove plate, a limiting plate, a bolt, a gasket and a conical spring, wherein a bolt hole is formed in the lower bottom of the groove plate, a limiting wing edge for the limiting plate is inwards arranged on the edge of a groove opening, the width of the limiting plate is matched with the groove pattern of the groove plate, the limiting plate nut is placed in the rack body and does not rotate relative to the rack body, the gasket, the conical spring and the limiting plate are sequentially placed in the groove plate from bottom to top, the groove plate penetrates through the bolt finally, a hole with the same shape and size as the bolt head is reserved in the middle of the limiting plate, the limiting plate is in a downward pressing state in the bolt fastening process, after operation is completed, the limiting plate bounces under the action of the conical spring and is flush with the position of the; the lower bottom of the groove plate is provided with a positioning folded edge. Like this, because the limiting plate does not have the rotation in the frid inside, consequently under the limiting plate effect, realize the locking of bolt not hard up, and the location hem that the frid was gone to the bottom set up fixes whole bolt locking subassembly on the rack body, and the effectual operating mode that prevents is under the vibrations leads to the bolt not hard up because of the reason of frid.

The invention is also characterized in that the lower bottom of the groove plate is provided with a positioning convex or concave structure, and the frame body is provided with a concave or convex structure matched with the positioning convex or concave structure arranged on the lower bottom of the groove plate. Like this, after the bolt-up, the frid has avoided the frid to take place the displacement under the vibrations operating mode through the protruding type of location or the concave type structure that matches each other to lead to the not hard up condition of bolt.

The invention is also characterized in that the rack body is provided with a concave structure matched with the lower bottom of the slotted plate. Therefore, after the slot plate is fastened by the bolts, the slot plate is directly embedded into the concave structure arranged on the frame body, and the slot plate cannot be displaced under the working condition of equipment.

The invention is also characterized in that the groove plate is fixed on the frame body, and the groove plate is fixed on the frame body through a welding machine or riveting or bolts. Therefore, the groove plate is directly fixed on the rack body, and the groove plate is better ensured not to be displaced.

The invention has the advantages that the device has simple structure, the process is easy to realize, the problem of looseness caused by rotation of the bolt can be completely avoided, and the structure can be used for connection of positions which are compact in structure and difficult to operate.
