The specific embodiment

Please refer to Fig. 1 to shown in Figure 5, the concrete structure that it has demonstrated the preferred embodiment of the utility model includes lock body 10 and locating bar 20.

Wherein, this locating bar 20 is used for fixedlying positioning to limit the rotation of bearing circle, one end of this locating bar 20 is provided with bonnet 21, be provided with a slide guide hole 22 for following slide guide bar insertion bearing fit on the positive leading flank of bonnet 21, this slide guide hole 22 extends along the direction of locating bar 20, be provided with a plurality of locked grooves 23 that distribute along slide guide bar direction of insertion spacing on the internal face of slide guide hole 22, this locked groove 23 is used for coordinating with following lock pin the upper locking bit of realization.

Be provided with protecgulum 11 and slide guide bar 12 on this lock body 10, this slide guide bar 12 is used for inserting slide guide hole 22 bearing fits of locating bar, and this protecgulum 11 is used for closing up with bonnet 21 tightly enveloping the bearing circle outer shroud.Be provided with a containing cavity 101 in lock body 10, this containing cavity 101 connects to enter in slide guide bar 12 backward, runs through forward the positive leading flank 102 of protecgulum 11.Tapered end 31, drive link 32 and lock pin 33 are installed in containing cavity 101, and the key hole of tapered end 31 is exposed on the positive leading flank of lock body 10, and lock pin 33 is installed in slide guide bar 12 and is controlled perpendicular to slide guide bar 12 telescopic movables by drive link 32 by tapered end 31.

Described slide guide bar 12 includes outer loop bar 121 and interior loop bar 122, should extend along its direction of insertion one by outer loop bar 121 self-locking bodies 10, and being provided with assembling entrance 123 in the free tail end of outer loop bar 122, in this, loop bar 122 self assembly entrances 123 axially are plugged in outer loop bar 121.The cross section of outer loop bar 121 and interior loop bar 122 is circular, is provided with the spacing block set 124 and the position-limited trough 125 that are fitted to each other between interior loop bar 122 and outer loop bar 121.

And, be provided with the guide groove 41 that extends along its direction of insertion on best described slide guide bar 12, be provided with projection 42 on internal face corresponding to aforementioned slide guide hole 22, this projection 42 stretches into bearing fit in guide groove 41, and be provided with retaining wall 43 in close free tail end one side of slide guide bar 12 of described guide groove 41, stroke when utilizing this retaining wall 43 to pull out with restriction slide guide bar 12 unlikelyly is drawn out excessive and deviates from the slide guide hole 22 of locating bar, makes troubles for next time upper latching operation.

The interior retracing spring 50 that preferably also is equipped with of described slide guide hole 22, slide guide bar 12 is butted on this retracing spring 50, utilizes this retracing spring 50 so that the elastic force that lock body 10 can eject away from locating bar 20 automatically when unblanking to be provided.

Principle of work or using method that the present embodiment is described in detail in detail are as follows:

During unlocked state, as shown in Figure 1 and Figure 4, its protecgulum 11 keeps certain distance each other with bonnet 21, vacate an opening that can supply automobile bearing circle outer shroud to pack in the below, in lock body, the tail end part of slide guide bar 12 still is plugged in locating bar in slide guide hole 22, and the lock pin 33 of slide guide bar 12 tail ends is bounced back, and away from the locked groove 23 in slide guide hole 22, not locking, slide guide bar 12 can be free to slide front and back in slide guide hole 22 like this.

When locking, as shown in Figure 5, the user needs first front and rear covers 11,21 to be placed on the outer shroud of vehicle steering, then promotes lock body 10, and front and rear covers 11,21 is drawn close each other, until front and rear covers 11,21 is fitted and gripped the outer shroud of vehicle steering.Wherein, this slide guide bar 12 slips into to the depths in slide guide hole 22, and lock pin 33 slides onto thereupon and is locked together on corresponding locked groove 23, and slide guide bar 12 can not slide, and is limited between lock body 10 and locating bar 20, realizes the locking function of locking.

When unblanking, the user only need to insert key in the key hole in dead ahead, and the lock core in rotational lock head 31, by drive link 32 band pendulum lock pin 33 retractions, deviates from locked groove 23 by lock core.At this moment, slide guide bar 12 is got back to the state that is free to slide again in slide guide hole 22, under the elastic force effect of retracing spring 50, this slide guide bar 12 outwards slippage automatically, make lock body 10 away from locating bar 20, front and rear covers 11, opened in 21 minutes, below open an opening, outside vehicle steering, ring can be deviate from from this opening, realizes unlocking function.

In sum, design focal point of the present utility model is, at first, it is arranged at tapered end with on the positive leading flank of the lock body of protecgulum, the key hole that makes tapered end is user oriented directly, be convenient to the user and find easily key hole and insert like a cork key, especially at the night that there is no light, bring convenience in use to the user.Secondly, it is arranged at locked groove the internal face of slide guide hole, and locked groove can be hidden in locating bar and not expose, and can effectively avoid locked groove to sustain damage and destroy.Moreover it utilizes coordinating of guide groove and projection, makes product more stable reliable in the process of slippage, and makes that the slide guide bar is unlikely to be drawn out excessive and to deviate from locating bar.

The above, it is only preferred embodiment of the present utility model, be not that technical scope of the present utility model is imposed any restrictions, therefore every foundation technical spirit of the present utility model all still belongs in the scope of technical solutions of the utility model any trickle modification, equivalent variations and modification that above embodiment does.
