Abstract

A wheel axle with a dust proof and locking connecting nut. The utility model comprises a wheel axle and a nut connected with one end of the wheel axle through thread; the utility model is characterized in that a spring clipping ring with a clipping platform which is not rotated oppositely to the wheel axle is arranged on the wheel axle. A screw cap is arranged on one end of the nut, and a plurality of locking grooves matching with the clipping platform are evenly distributed on the periphery on the other end. Because above technical proposal is adopted, the utility model has the advantages of high connecting intensity and reliable connection, the utility model prevents the thread to be exposed during working, performing the function of dust and damage prevention, and prevents the nut to be dropped off because of being loosened.

Description

Has wheel shaft dustproof, the retaining attaching nut

Technical field

The utility model relates to a kind of wheel shaft, particularly a kind of wheel shaft with the attaching nut.

Background technique

Existing bicycle shaft; the structures such as boss bolt of two-wheel wheel axle or motor tricycle wheel axle and truck; because their wheel shaft all is to work under the environment of vibration; nut tends to become flexible; particularly the wheel shaft of four-wheel beach buggy is to move on more abominable road; in order to prevent vibration; do not make its attaching nut loosening and come off; as shown in Figure 1, usually on bolt, bore an aperture, insert cotter pin and prevent that nut from withdrawing from; screw thread is exposed; can not prevent dust, screw thread also can not get protection, dismounting inconvenience; also can damaged screw in when dismounting, and reduced join strength.Therefore for solving exposing of screw thread, also just use dustproof nut, as shown in Figure 2,,, can not solve owing to the loosening of nut comes off though it can play effect dustproof and the protection screw thread by the attaching nut of the dustproof nut of mounting strap on wheel shaft.

Summary of the invention

The purpose of this utility model just provides a kind of join strength height and has wheel shaft dustproof, the retaining attaching nut reliably with being connected, it can prevent that not only screw thread from exposing the effect of playing dustproof and antisitic defect at work, can also prevent that nut is owing to the loosening double action that comes off.

The purpose of this utility model is that following technological scheme realizes, promptly a kind of have a wheel shaft dustproof, the retaining attaching nut, comprises wheel shaft and the nut that is threaded with wheel shaft one end; It is characterized in that: on wheel shaft, be set with not the spring collar of the band Ka Tai of wheel shaft rotation relatively; One end of described nut is provided with nut, the uniform locking trough that several match with Ka Tai on the circumference of its other end.

Wheel shaft in the utility model is installed on the wheel hub, and fix by spring collar and nut, mating face on the wheel shaft and the plane on the spring collar are cooperatively interacted, be in order to prevent that spring collar work from the time rotating on wheel shaft, the Ka Tai of its spring collar is against on the cell wall of locking trough of nut, because spring collar can not rotate, be against on the locking trough by Ka Tai, it is loosening that nut the time can not be produced in work, reached the purpose of nut anti-back, make be threaded more reliable; On nut, be provided with dustproof nut in addition again, prevented that the screw thread on the wheel shaft from exposing, it is played a very good protection.When dismounting, only need back down the Ka Tai in the nut locking trough with general instrument, swivel nut withdraws from again, its easy accessibility.

Owing to adopted technique scheme, the utlity model has the join strength height and be connected reliable advantage, it can prevent that not only screw thread from exposing the effect of playing dustproof and antisitic defect at work, can also prevent that nut is owing to the loosening double action that comes off.

Embodiment

The utility model is described in further detail below in conjunction with drawings and Examples:

Shown in Fig. 3,4,5,7 or 8, the utility model comprises wheel shaft 1 and the nut 2 that is threaded with wheel shaft one end; It is characterized in that: on wheel shaft, be set with not the spring collar 3 of the band Ka Tai of wheel shaft rotation relatively; One end of described nut is provided with nut 6, the uniform locking trough that several match with Ka Tai 7 on the circumference of its other end.

Shown in Fig. 5 or 8, in order to prevent that spring collar from rotating on wheel shaft, have breach on the described spring collar 3, an end wherein upwards is bent to form card platform 4, inner ring at spring collar is provided with one section plane, and the position of matching with the plane on the spring collar at wheel shaft is provided with mating face 5.This spring collar also can be a non-threaded section fluting at wheel shaft, in spring collar, be provided with the boss that matches with groove on the wheel shaft, make boss be positioned at groove and prevent to rotate, rotate and otherwise to be installed on the wheel shaft as required as long as can prevent spring collar certainly.

Shown in Fig. 6 or 8, can be reliably backed down in order to make the card platform from the locking trough of nut, to obtain bigger yielding space, wheel shaft 1 is provided with split washer 8, the opening on this back-up ring and the card platform 4 corresponding formation on the spring collar 3 breach of stepping down.

As shown in Figure 8, wheel shaft in the utility model is installed on the wheel hub 9, on wheel shaft, load onto split washer successively, spring collar 3 backs are fixed by nut 2, mating face 5 on the wheel shaft 1 is cooperatively interacted with plane on the spring collar, be on wheel shaft, to rotate when preventing spring collar 3 work, the card platform 3 of its spring collar 3 is against on the cell wall of locking trough 7 of nut 2, because spring collar 3 can not rotate, be against on the locking trough 7 by card platform 4, it is loosening that nut 2 can not be produced when work, reached the purpose of nut anti-back, make be threaded more reliable; On nut, be provided with dustproof nut in addition again, prevented that the screw thread on the wheel shaft from exposing, it is played a very good protection.When dismounting, only need back down the Ka Tai in the nut locking trough with general instrument, swivel nut withdraws from again, its easy accessibility.
