Description

Locknut assembly

Technical Field

The utility model belongs to the technical field of the nut, especially, relate to a locknut subassembly.

Background

The patent with the name of a locknut is disclosed in the existing Chinese patent database, the application number is CN201922228707.9, the application date is 20191212, the publication number is CN211599241U and the publication date is 20200929, the patent comprises two lockhalf nuts, the middle of each lockhalf nut comprises a bolt hole, the upper surface or the lower surface of each lockhalf nut is an inclined surface, and the inclined surfaces of the two lockhalf nuts are matched to form a butt joint surface so that the two lockhalf nuts can be uniformly installed; one of the anti-loose half nuts is an upper nut, and the other anti-loose half nut is a lower nut; the two anti-loosening half nuts respectively comprise positioning holes which are through holes, and when the two anti-loosening half nuts are matched to form an integral nut, the positioning nails are inserted into the two positioning holes, so that a wrench can conveniently twist; after being screwed, the positioning nail is detached; more convenient counterpoint when screwing, adopt box spanner or other instrument screw in once together after two mate nuts stack, its weak point lies in: the nut overturns the existing integral nut structure, becomes an assembled structure, increases the difficulty of process machining, has the possibility of separation between two anti-loosening half nuts of the nut, leads to the falling and loosening of a peripheral bolt, and has certain limitation.

SUMMERY OF THE UTILITY MODEL

The to-be-solved technical problem of the utility model is that current nut is relatively poor to the locking effect of bolt, in order to improve its weak point, the utility model provides a locknut subassembly.

In order to achieve the purpose, the utility model is realized by the following technical proposal:

the utility model provides a locknut subassembly, including the nut body, set up flutedly on the nut body upper surface, recess and the coaxial setting of nut body, be provided with elastic rubber piece in the recess, elastic rubber piece is through connecting piece and nut body fixed connection, set up the back taper hole with the internal thread switch-on of nut body on the elastic rubber piece, the back taper hole is with the coaxial setting of nut body, vertical interval is provided with a plurality of beads on the internal surface of back taper hole, when the peripheral hardware bolt connects to elastic rubber piece's back taper downthehole soon from bottom to top, and the ascending bead free end of slope is contradicted in the thread of peripheral hardware bolt.

The utility model discloses the during operation, when the peripheral hardware bolt connects to the nut body from bottom to top soon, the thread of peripheral hardware bolt connects to the back taper of elastic rubber piece downthehole along the incline direction of bead soon, the bead can not produce the conflict power to the peripheral hardware bolt thread, when peripheral hardware bolt top-down back-out to the nut body outside, the thread of peripheral hardware bolt revolves out from the back taper of elastic rubber piece downthehole against the incline direction of bead, the bead produces very big conflict power to the peripheral hardware bolt thread, prevent the back-out of peripheral hardware bolt.

Compared with the prior art, the beneficial effects of the utility model are that: because the complex setting of elastic rubber piece and bead utilizes the incline direction of bead, has outwards established the bolt and has screwed out to the nut body and carried out the restriction outward, has played locking effect, and the device can apply to industrial production, has very strong practicality.

Threaded holes are formed in the inner bottom surface of the groove, through holes are formed in the elastic rubber block opposite to the threaded holes, the connecting piece is a fixing bolt, each fixing bolt sequentially penetrates through the corresponding through hole and the corresponding threaded hole to connect the elastic rubber block with the nut body, and the head of each fixing bolt abuts against the upper surface of the elastic rubber block.

And a flat pad is arranged between the head of each fixing bolt and the elastic rubber block.

A gap is arranged between the groove and the elastic rubber block, and a damping layer is filled in the gap. The damping layer is made of viscoelastic materials, friction force between the elastic rubber block and the inner wall of the groove is increased due to the arrangement of the damping layer, and the stability of connection between the elastic rubber block and the nut body is improved.

Drawings

Fig. 1 is a schematic structural diagram of the present invention.

In the figure: the novel nut comprises a nut body 1, a groove 2, an elastic rubber block 3, a connecting piece 4, a fixing bolt 401, an inverted conical hole 5, a convex edge 6, a threaded hole 7, a through hole 8, a flat pad 9 and a gap 10.

Detailed Description

The technical solution of the present application will be further described and explained with reference to the accompanying drawings and embodiments.

As shown in fig. 1, a locknut assembly, including nut body 1, nut body 1 is provided with recess 2 on the upper surface, recess 2 and the coaxial setting of nut body 1, be provided with elastic rubber piece 3 in the recess 2, elastic rubber piece 3 is through connecting piece 4 and nut body 1 fixed connection, set up the back taper hole 5 with the internal thread switch-on of nut body 1 on the elastic rubber piece 3, back taper hole 5 and the coaxial setting of nut body 1, vertical interval is provided with a plurality of beads 6 on the internal surface of back taper hole 5, when the peripheral hardware bolt connects to the back taper hole 5 of elastic rubber piece 3 from bottom to top in, the ascending bead 6 free end of slope is contradicted in the thread of peripheral hardware bolt. Set up threaded hole 7 on the bottom surface in the recess 2, all seted up through-hole 8 on the elastic rubber piece 3 that each threaded hole 7 is just right, connecting piece 4 is fixing bolt 401, and each fixing bolt 401 passes corresponding through-hole 8 and the threaded hole 7 that corresponds in proper order, is connected elastic rubber piece 3 and nut body 1, and each fixing bolt 401's head is contradicted on elastic rubber piece 3's upper surface.
