Problems solved by technology

[0007] The improvement and improvement of the direction of friction and adhesion between bolts requires many implementation procedures and inconvenient disassembly, and some can only be dismantled by destructive methods, which cannot be reused, and the fastening effect is not completely ideal
The new type of anti-loosening fastener applied by the applicant in the previous period realizes structural anti-loosening between bolts and nuts by adding the connecting piece of shaft center lock, and the effect is fundamentally and substantially improved compared with the existing technology. However, the technical solution previously applied by the applicant will be inconvenient during installation, and the requirements for the bolt and shaft lock structure will also increase the processing cost and raw material cost

Embodiment 1

[0041] Embodiment 1: as Figure 1-3 As shown in 12, a super fastening kit includes bolts, nuts, and shaft locks, the bolts include screw rods, the nuts are hexagonal nuts, and the shaft locks are hexahedral and can be socketed on the nut Together, it also includes a circular motion limiting mechanism that prevents the screw and the nut from rotating with each other, that is, a strip-shaped limiting groove located outside the screw rod and a strip-shaped limiting groove located at the distal end of the shaft lock and the strip-shaped limiting mechanism. The circlip shrapnel that fits the bit groove, the axial movement limiting mechanism that prevents the shaft lock and the nut from falling off each other, that is, the nut card slot on the side wall of the nut and the shaft lock The nut retaining spring at the proximal end and adapted to the nut retaining groove has three strip-shaped limiting grooves and retaining spring springs, which are distributed in a three-legged shape, a...

Embodiment 2

[0045] Embodiment 2: as Figure 4-6 , 12, the difference between this embodiment and embodiment 1 is that the circular movement limiting mechanism is an irregular limiting slot arranged at the tail end of the screw and an irregular limiting slot arranged at the distal end of the shaft lock and the The irregular limit slots are adapted to the circlip springs, and the irregular limit slots and the matched circlips are in the shape of one-way propellers, and the cross-section of the irregular limit slots is irregular , the depth of the limiting slot in the axial direction of the screw rod can just accommodate the height of the clip spring piece, and can also be greater than the height of the clip spring piece.

Embodiment 3

[0046] Embodiment 3: The difference between this embodiment and Embodiment 1 is that the circumferential movement limiting mechanism and the axial movement limiting mechanism are helical limiting grooves and The circlip shrapnel provided at the distal end of the shaft lock and matched with the helical limiting groove, there are three helical limiting grooves, and one circlip shrapnel, the two form a single ratchet mechanism for movement.

[0047] Installation method: 1. Screw the nut into the screw rod to the predetermined position where the circlip shrapnel can be inserted into the helical limit groove; 2. Put the shaft lock on the nut and tighten it ; 3. Pull out the shaft lock until the spring springs fall into the helical limit groove, or turn the shaft clockwise or counterclockwise until the spring springs fall into the spiral The limit groove is used to simultaneously limit the circumferential movement and the axial movement.

[0048] Disassembly method: 1. Insert the ...

Abstract

The super fastening kit of the present invention includes bolts, nuts, and shaft locks, the bolts include screw rods, and the shaft lock is a polyhedron whose shape matches the shape of the nuts. A circular movement limiting mechanism that rotates with the nut and an axial movement limiting mechanism that prevents the shaft lock from falling off from the nut, and the shaft lock is limited by the circumferential movement limiting mechanism and the axial movement The mechanism is sleeved on the nut and the screw at the same time, and is fixed to each other and integrated. The product structure of the present invention is reasonable in design, easy to process, and achieves better anti-loosening effects. At the same time, it saves material costs and processing costs, and improves the work efficiency of workers. Reduce the workload of workers, and can also be used as an anti-theft connection.

Description

technical field [0001] The invention belongs to the technical field of connecting fasteners, and in particular relates to a super fastening set. Background technique [0002] Bolts and nuts are the most commonly used connecting fasteners in the mechanical field. Most of the commonly used bolts and nuts are [0003] It is an ordinary standard fastener. Under the action of shock, vibration or heavy load, the friction between the thread pairs gradually decreases or disappears instantly, resulting in loose threaded connection, and even the fastener falls off or is lost, which will cause the mechanical The device is malfunctioning. [0004] In Japan's eccentric nut technology, the double nut structure is adopted to increase the radial force of the nut and the screw [0005] The amount to increase the friction, the anti-loosening effect is currently recognized as the best in the world. In Germany's anti-loosening gasket technology, the double gasket structure is used to indirec...
