Description

Telescopic lock for steering wheel

The utility model relates to a kind of telescopic type handle lock, belongs to lockset and so on.

Along with the progress of science and technology, the prosperity of society, product is towards light, thin, short, little trend development.Handle lock pattern system the earliest is turns battle shape, and its two ends are colluded respectively and are stuck on bearing circle and the brake pedal, and this kind lockset in use, and is extremely inconvenient, and its length is long, and easy-to-collection does not cause it almost to be eliminated by market.The person of replacing, for a kind of fork peaks at the Lockset on steering wheel of bearing circle two respective side, so if this kind lockset promptly can be because of the setting of bearing circle central security air bag be used to the to have safety air bag bearing circle of (Air Bay), make its card that slightly protrudes from bearing circle, so that this kind lockset can't use.And with the raising of modern to the Motor Vehicle Safety Standard requirement, in a foreseeable future, the automobile with safety air bag is will definitely beneficial shape general, therefore, can not be applicable to the lockset of the bearing circle with safety air bag, also certainly will will suffer exit.Though now being arranged on the market, a kind of handle lock of adopting the single-point snap close can separate this problem, i.e. person as shown in Figure 1, right its length is fixing and can't save receipts, the shortcoming of collection inconvenience still exists, its grip tab system is connected as a single entity with core, during use, system inserts in the core with key, and force in key, and drive core and grip tab to be fastened on the locking bar, no matter lock or unblank all must use key, very inconvenience in the use, again because of this grip tab and core system position in one of locking bar end, if locking bar is embedded in the angle of bearing circle deviation is arranged slightly, what can cause promptly that grip tab can't fasten is the devil.

In order to overcome the problem of above-mentioned existence, the purpose of this utility model can save locking bar and receives and rotation, and rotating rod lock can make the tongue piece of buckling element be fastened on bearing circle, and need not use key to finish when locking, when unblanking, finish the telescopic type handle lock of the warming-up exercise of locking next time again automatically.

The utility model is a kind of telescopic type handle lock, and it can make the locking bar joint receive short distance, and is buckled in the lock structure of bearing circle with spinner direction single-point lock.It mainly is in the hollow cylindrical outer tube, the buckling element that suit one is concentric, and this buckling element can have a vertical strip shape and wear slotted eye, and in the outer tube front end core is set according to the radian rotation of outer tube wall on the tube wall of outer tube.Buckling element system is connected a cylindricality newel post respectively with microscler arc sheet two ends and is formed.Be convexly equipped with a tongue piece in the middle section of arc sheet and according to former radian.Then the cambered surface of newel post is provided with a retracing spring, and its two end is individually fixed on back newel post and the outer tube wall, and in its narrow footpath part axle sleeve one retracing spring, makes the tongue piece normality be the position of withdrawing from slotted eye, promptly locates stand-by state.In buckling element, be nested with a tubulose locking bar again, it can be received by slip joint in buckling element, after locking bar is extracted out, just can make locking bar and buckling element borrow tooth, the mutual buckle of groove makes buckling element and borrow the guiding incline of core latch with the locking bar turn, makes the buckling element can be without key, can be with snap close direction unidirectional rotation, but can't reversely trip.During use, outer tube is located with one of its slotted eye embedding bearing circle according to the tangential direction of bearing circle, can rotate locking bar this moment and drive buckling element, make its tongue piece be fastened on the place, point of contact of bearing circle, can finish and be buckled in bearing circle with single-point lock, very convenient fast, and applicable to the bearing circle of various forms.When unblanking, only key must be inserted lockhole and reverse, make no longer blocking buckling element of core latch, can withdraw from slotted eye, finish and trip, finish the warming-up exercise of locking next time simultaneously by means of retracing spring.When not using, locking bar is pressed in the outer tube, to shorten its length, be convenient to collection.

The utility model has following advantage compared with the prior art:

1. locking bar can stretch, and when being convenient to not use, the locking bar joint is received, and to shorten its length, is convenient to collection;

2. when locking, need not use key to finish, when unblanking, finish the warming-up exercise of locking next time automatically, to reach effect easy to use;

3. safe and reliable.

Characteristics of the present utility model can also obtain further instruction from the following drawings and embodiment.
