Abstract

A locknut assembly. Including the bolt, the packing ring, nut interconnect fastens, the interior circle of packing ring is equipped with the arch of the same interior circle, the outer fringe size and the shape of bellied outer fringe size and shape and nut are the same, the nut is mutually inconsistent and extrudees with the arch, the right angle groove that the nut was established corresponds the counterbalance with the 1 font lug that the arch was established, the acute angle in right angle groove is the same with the orientation of nut precession bolt, when the nut pine moves back, thereby the skewed slot face in nut right angle groove is supported and is pressed 1 font lug and not have the unable formation pine of gap space and move back, when needing the pine to move back, simultaneously the pine moves back the nut and the arch just can together. The friction force between multiplicable packing ring of processing friction structure line and the component on the back of bellied washer face, circle processing screw thread can be when the mounting nut in the packing ring, and 1 font lug on the arch can better correspond the right angle groove, and this kind of locknut subassembly design, simple structure, the locking of nut moves back the effect better and need the pine move back also convenient.

Description

Locknut assembly

Technical Field

The utility model belongs to the technical field of the fastener and specifically relates to a can prevent locknut subassembly that pine moved back.

Background

The bolt is a common fastener, consists of a head and a threaded screw, needs a nut to be matched for use, is used for connecting and fastening different components with through holes, and is extremely wide in application. A space gap is formed between the screw thread of the nut and the screw thread of the bolt, and the screw thread of the nut freely rotates along the screw thread of the bolt to advance and retreat. In order to increase the contact area between the nut and the connected member and prevent the nut from loosening due to vibration, a washer is usually placed on a screw rod between the member and the nut, the washer is usually a round flat washer, the outer circle and the inner circle of the round flat washer are all concentric circles, the inner circle has no internal thread, but in the practical application process, when bolts connecting different members are vibrated for a long time, the situation that the nut is loosened and withdrawn is still easy to occur, accidents and economic losses are caused, so the nut is frequently required to be screwed in again for reinforcement, and great inconvenience is caused.

Disclosure of Invention

In order to overcome the defect that when different components are fastened by the conventional bolt connection, the nut cannot be effectively prevented from loosening due to the influence of vibration, the anti-loosening nut assembly which has better anti-loosening and withdrawing effects and is convenient to loosen and withdraw when needing to loosen and withdraw is provided.

The utility model provides a technical scheme that its technical problem adopted is: the utility model discloses a bolt, the packing ring, the nut, it has the arch of same interior circle to establish round edge in the packing ring, it is the same with nut outer fringe size and shape to establish protruding outer fringe size and shape, it is equipped with 1 style of calligraphy lug on the convex surface of protruding and nut contact to establish, 1 style of calligraphy lug falls into two parts with the convex surface, establish and be equipped with the right angle groove on the nut face of nut and protruding contact, the right angle groove falls into two parts with the nut face, it is the same with the orientation of nut precession bolt to establish right angle groove acute angle orientation, when the nut precession bolt fastening, the nut extrusion is protruding, it corresponds nut right angle groove and jack-up nut right angle groove to establish 1 style of calligraphy lug of bellied and, the oblique groove face extrusion 1 style of calligraphy lug in the right angle groove of nut does not have the unable motion in gap space, the nut is unable pine moves back. The back of the raised washer surface can be provided with friction structure grains. An inner circle thread may be provided on the inner circle of the washer.

The beneficial effects of the utility model are that, when the different components of bolted connection fastening, the nut touches and extrudees with the packing ring arch mutually, nut right angle groove and jack-up nut are corresponded to bellied 1 style of calligraphy lug, nut screw thread and bolt screw thread support each other to press and do not have the space gap, the frictional force that nut screw thread and bolt screw thread produced each other hinders that the nut receives vibrations to produce the pine and moves back, when the nut that receives vibrations simultaneously produces the pine and moves back, the slash face extrusion bellied 1 style of calligraphy lug in right angle groove on the nut does not have the space motion in gap, thereby the nut can't form the pine and moves back, when needing the pine to move back, because of protruding outer fringe size and shape and nut outer fringe size and shape are the same, simultaneously the nut is moved back in the pine together and has bellied packing ring just can. The back of the raised washer face is provided with friction structure grains, and under the action of nut fastening and extrusion, the friction structure grains of the washer and the contacted components can increase the mutual friction force, so that the washer is not easy to loosen, and the nut cannot be loosened. The round processing screw thread in the packing ring cooperates the rotatory advance and retreat of bolt screw thread, is convenient for when the mounting nut for the bellied 1 style of calligraphy lug of packing ring just corresponds the right angle groove of nut when precession bolt and reaches nut fastening member. The locknut component is simple in structure and good in locknut loosening prevention effect.

Detailed Description

In fig. 1, fig. 2, fig. 3, fig. 4, fig. 5, fig. 6, fig. 7, bolt (1), nut (2), packing ring (3) interconnect is supported and is pressed, there is arch (4) on packing ring (3), the protruding outer fringe size and shape (5) of arch (4) are the same with nut outer fringe size and shape (15) of nut (2), be equipped with 1 font lug (7) on protruding (6) that arch (4) and nut (2) touched, 1 font lug (7) divide into two parts with convex surface (6), it has right angle groove (9) to open on nut face (8) that nut (2) and arch (4) touched, groove (9) divide into two parts with nut face (8), nut (2) support and press arch (4), right angle groove acute angle (10) direction of right angle groove (9) of nut (2) is the same with nut precession direction (11), nut (2) receive the shake to produce and loose, right angle groove (9) of nut (2) just can's unable right angle groove (12) move back because of clearance (12) on the nut (2) and the clearance can's form together when not moving, thereby can's the clearance can's not move back because of clearance (2) together with arch (4) because of clearance. The back at the face of arch (4) place of packing ring (3) processes friction structure line (13) of multiplicable frictional force, under the effort of nut (2) fastening extrusion packing ring (3), friction structure line (13) and the component that contacts of packing ring (3) multiplicable mutual frictional force, make packing ring (3) more difficult pine move back, nut (2) more can't form the pine and move back, processing interior round thread (14) cooperation bolt (1) rotation advance and retreat on the interior circle of packing ring (3), be convenient for when mounting nut (2), make 1 style of calligraphy lug (7) on arch (4) just can correspond right angle groove (9) of nut (2) when precessing until nut (2) fastening component.
