Description

Telescopic theft proof lock for automobile

The utility model relates to a kind of scalable sleeve-type automobile anti-theft lock, and it can freely be installed on the vehicle steering, and the restriction bearing circle rotates, and prevents that automobile is stolen, belongs to the automobile anti-theft lock field.

The kind of alarms and security systems for automobiles is a lot of at present, one type is the electronic alerts stop motion mechanism, these devices can make vehicle not start, unless key or electronic cipher by a kind of special use of people of approving are handled, but the shortcoming of this device is to cost an arm and a leg, et out of order, and electronic alerts device easily is contained in below the car engine cover usually, and a ripe burglar in this road can find it at an easy rate and make its disconnection.Another kind of type is that the phase between the restriction vehicle interior steering controller extremely moves, to prevent vehicle take-offs, it uses the relative place, two ends of elongated shape lockset of its adjustable in length that a pair of hook is installed, hook is connected on the brake pedal, another hook is around on the steering wheel rim, control this all activity relative to each other of two parts, feel inconvenient when the shortcoming of this device maximum is the complicated operation use.

The purpose of this utility model provides a kind of scalable sleeve-type automobile anti-theft lock that steering wheel for vehicle changes spine move that limits.

The purpose of this utility model realizes by following array structure: have a gain at a hollow sleeve member middle part, ligule arc plate with sleeve circular arc identical radian measure is housed in the gain, one end of ligule arc sheet is applied mechanically connecting pin with tooth and is connected, and the other end of ligule arc plate connects the tooth lid with connecting pin; One end of sleeve member has circular hole, the lock core cover is housed in the circular hole, the lock core cover is captiveed joint with sleeve member, lock core is contained in the lock core cover and is connected tooth with connecting pin and covers, lock core puts lock bolt is housed in the aperture, in the afterbody hole of the two free-running fit, lock bolt spring is housed, another free end of spring is supported by left end cap, and left end cap is by on the connecting pin bonded assembly sleeve body; The other end of sleeve member a flexible is housed is contained in the locking bar spare in the sleeve member, and locking bar spare one end has a series of vertically adjacent ratchets, and the other end is with Anti-slip handle.Feature of the present utility model also is a series of vertically adjacent ratchets of an end of tooth cover, and the other end has aperture, and it is by being connected in the sleeve that torsion spring, lock core cover and lock core are housed in the aperture.

During use, at first lock is placed the open position, extract the ratchet that locking bar puts ratchet that tooth covers and tooth out and be meshing with each other, gain is aimed at vehicle steering rotation lock rod member, ligule arc sheet rotates, the tooth lid of captiveing joint with ligule arc sheet also rotates, and ligule arc sheet blocks square plate, and at this moment direction is protruding in sleeve gain inner chamber, locking bar spare can not push in the sleeve again, locking bar spare outwards appears elongation, the rotational angle of restriction bearing circle, thus reach antitheft purpose.

The utlity model has easy to operately, in light weight, simple and compact for structure, be difficult for breaking advantage such as destruction, theftproof performance is good, be suitable for various types of automotive uses.

Be further described with regard to embodiment of the present utility model below in conjunction with accompanying drawing

Fig. 1 is the structural representation of the utility model device;

Fig. 2 is the A-A section drawing of the utility model device;

Fig. 3 is the left view and the part sectional view of tooth lid;

Fig. 4 is the running condition figure of the utility model device;

Fig. 5 is the B-B section drawing of the utility model device.

Lock tube (1) middle part has a gain and circular hole, lock core cover (11) is housed in the circular hole, the two is welded as a whole, load onto lock core in the macropore of lock core cover, connect with connecting pin (13), lock core puts tapping dress lock bolt (12), the two free-running fit, shock mount (14) in lock bolt (12) the afterbody hole, the other end of spring is pushed down by left end cap again, ligule arc sheet (4) is contained in lock tube middle part inner chamber, and wherein an end is connected with fluted disc (3) with connecting pin (13), one side fluted disc have an angle, another side is the skewed slot at right angle, its end face riveting has a backing pin (16), and the other end is connected with tooth cover (6) by connecting pin, inserts the free end of torsion spring (7) in the aperture of tooth cover back, also be inserted with torsion spring (7) in right end cap (8) aperture, right end cap (8) is connected pin equally with lock tube (1) and is connected.

During use, can opening will originally be installed on earlier, take off key, extract locking bar spare out, making ratchet (19) and tooth cover (6) on the tooth lid (5) go up ratchet (18) is meshing with each other sleeve gain portion is placed on and rotates the plastics Anti-slip handle on the bearing circle, the tooth lid (3) of captiveing joint with ligule arc sheet also and then rotates, groove inclined-plane on the tooth lid (3) is just in time also on hand of rotation, lock bolt also has same inclined-plane on (12), it produces the axial component of a parallel lock bolt axis, lock bolt (12) is retreated, when ligule arc sheet blocks (encasing) bearing circle and no longer rotates, the last groove of fluted disc (3) is aimed at lock bolt (12), lock bolt enters in the groove under the effect of spring (14), fluted disc (3) and ligule arc sheet (4) all can not be rotated, this device can not take off from direction, at this moment because bearing circle has occupied the space in the telescopic pipe, locking bar (10) part of extracting out can not push its inner chamber again, locking bar spare outwards protrudes, this moment, desire was rotated, then lived by the cab space shelves, the rotational angle of bearing circle is restricted, and reaches antitheft purpose.

When unblanking, the off-centre that key (12) is stirred on the lock core (2) makes lock bolt withdraw from the teeth groove (7) of fluted disc (3), the amount of torsional energy of storing in torsion spring (7) locking process discharges, make tooth cover and ligule arc sheet rotate back into original position together, go back to the position and determine (till keeping off lock core cover (11) to backing pin (16)) by the backing pin (16) that is riveted on the fluted disc, after this device took off from bearing circle, locking bar can push in the sleeve (1).

This device has when locking and can take off key and operate, need only rotate when unblanking key just automatically the characteristics of cycle, easy and simple to handle reliable, physical dimension is little, connecting pin connects for selling directly to households, firmly the advantage such as non-dismountable is fit to the antitheft of any vehicle.
