Description

Direction location lock

The utility model relates to a kind of direction location lock that locks motor vehicle steering wheel.

The antitheft of motor vehicles undertaken by the driver's cabin car door lock mostly, is to use padlock not having on the motor vehicle of driver's cabin, and chain is united and finished.Also having a class anti-theft device is to adopt lock, handle lock is fixed on a permanent position, it can not freely be rotated, current lock steering wheel arrangement device has two kinds, a kind of is to adopt two metal round cover, the upper and lower center that is fixed on steering wheel, make upper and lower cover and steering wheel be linked to be an integral body, have a locating hole under the bottom cover, on the axle sleeve of steering wheel bottom, a lock is installed, key is twisted lock core after inserting, upwards string is moving to drive lock pin indirectly, makes lock pin enter the purpose that reaches locking direction in the locating hole.Another kind is that a lock is installed on the axle sleeve of the bottom of steering wheel, have a locating hole on the axle of turning center, key is twisted lock core after inserting, drive lock pin indirectly, lock pin is inserted in the hole of turning center axle, make the turning center axle together with permanent position of steering wheel locking, can not freely rotate.Because these two kinds of direction location locks all are indirect drive, lock pin is inserted in the locating hole, thereby reliability is relatively poor, in addition in vehicle traveling process, because vibration force is big, vibrate key sometimes and drive the lock core rotation, promote lock pin near locating hole, or enter in the hole, the operation of steering wheel is caused certain influence.

The purpose of this utility model provides a kind of direct transmission locking, opens safe and reliable direction location lock.

The purpose of this utility model is achieved in that in the bottom of steering wheel fixes a location lock, and the lock core and the lock pin of location lock are as a whole, and one side has a locating notch on the top of axle sleeve, and lock pin is corresponding mutually with the size and the position of locating notch.

In order to guarantee the security reliability after direction location lock is opened, on lock core, be with a safety spring, by elastic force the location is locked under the situation of unlatching, lock pin is difficult for entering breach.

Like this,, only need insert lock core, turn lock core, make lock pin directly insert locating notch on the axle sleeve, transfer to key, steering wheel is fixed up, can not rotate again with key in closing direction when lock location.After location lock is opened, because the effect of safety spring, make the direction lock not only reliably but also safety.

Below in conjunction with accompanying drawing the utility model is described in detail

Fig. 1 is the structural representation of direction location lock

Steering wheel 1 bonds together with circular metal framework 2 as shown in Figure 1, on turning center axle 3, have a keyway 4, circular metal framework 2 is set on the turning center axle 3, be embedded in the metal retainingf key at keyway 4 then, with nut 5 circular metal framework 2 tightened again, like this, steering wheel 1, circular metal framework 2, turning center axle 3 just are connected to an integral body, and they can rotate with respect to the fixed hub 6 of lower end.Following circular metal framework 2 one sides at steering wheel 1 are bumped into a location lock, will locate lock with screw 13 and fuse with circular metal framework 2.Lock core 7 is as a whole with lock pin 8, arranged around at lock core 7 has snap 9, per three symmetrical, wherein have in the spiral sliding tray 10 on the snap insertion lock core, when closing the location lock, lock core can rotate by the hand of spiral, twists the key flexibility and reliability like this, a side has a locating notch 11 on the top of axle sleeve 6, and its size is corresponding with lock pin with the position.

After guaranteeing that the direction lock is opened, prevent lock pin 8 because the vibration effect enters locating notch 11, on lock core 7, be with a safety spring 12, make the pin core that an elastic force outwards be arranged, avoid driving because of vibration key 14 and pin core 7, make lock pin, guarantee traffic safety near locating notch 11.

During the closing direction lock, available key 14 inserts in the lock, rotates and push lock core, and lock pin is entered in the locating notch, extracts key, and steering wheel 1 just can not freely rotate and reach antitheft purpose like this.If when opening, key can be inserted rotate in the lock and withdraw from lock pin, steering wheel just can freely rotate again like this.

Claims (2)

1, a kind of direction location lock that constitutes by location lock, steering wheel, axle sleeve, it is characterized in that fixing a location in the bottom of steering wheel (1) locks, the lock core (7) of location lock is as a whole with lock pin (8), a side has a locating notch (11) on the top of axle sleeve (6), and lock pin (8) is corresponding with the size and the position of locating notch (11).
