The utility model is composed of a lock body, a hinged disk, etc. The universal safety lock can be fixedly installed on the front bracket and the back bracket of the vehicle to lock the front wheel and the back wheel, and the universal safety lock can also be used for locking the doors, the windows, etc. The universal safety lock has the advantages of convenient use, strong firm safety performance, simple structure and low cost.

Description

Universal safety lock

The utility model relates to the lock device of a kind of fixable lock bicycle, tricycle, motorcycle and door and window.

The utility model is at general theftproof lock utility model patent (number of patent application: 90226382.X) technical renewal.The shortcoming of original technology is: one, locking can not return, and needing two hands to cooperate could locking; Two, unblanking can not stop, and key is lost easily; Three, door bolt thick stick return can not stop, has unsafe factor.

The purpose of this utility model is the improvement the deficiencies in the prior art, and providing a kind of can singlehandedly realize closing, unblanking, the stop of door bolt thick stick energy, the general widely Wan An of function lock technology.

The utility model is to realize like this.The return of tapered end 7 and stop device are to have Ra, b hole 18, return spring 21, the chamber on the lock core 16 to put design gathering sill 25 arranged by the design that matches of the lock core 16 in lock housing 15 endoporus, and stop hole 26 and trapezoidal axle 23, spring 24 mutual restriction realize.Unblank, key 8 core 16 of unblanking turns clockwise 90 °, the step jack-up return spring 24 in Ra hole 18, Ra hole and Rb hole by overlap variation from, in vertical state.At this moment, stop hole 26 on the

gathering sill

25 and 23 couplings of trapezoidal axle, lock core 16 is subjected to stop, and key 8 can not be extracted.Locking coils 9 when rotation tangles, and makes the trapezoidal axle 23 that buckles in the 5 jack-up tapered ends 7 on the door bolt thick stick 4 leave stop hole 26, return spring 21 makes lock core 16 turn round 90 ° automatically, and lock shaft hole 20 overlaps with lock shaft 19, when extracting key 8, lock shaft 19 falls in the lock shaft hole 20, realizes automatic blocking.

The stop device of door bolt thick stick 4 be on the dish 9 that tangles with protective case 2 on design one coaxial and different-diameter, the separable a that overlaps, b hole 12 are arranged, device spring 14 and steel ball 13 in the b hole, remove change hands handle 3 tangle the dish 9 half-twists, the inwall of protective case 2 forces steel ball 13 all to enter the b hole.After unblanking, torsion spring 11 makes dish 9 revolutions that tangle, and door bolt thick stick 4 return a, b hole overlap, and 1/3 steel ball enters a hole, and 2/3 still in the b hole, thereby realizes that door bolt thick stick 4 is ensured public security by stop.

The protective case 6 of device tapered end 7 and device tangle and coil 9 protective case 2, and available ring stand 1 is made a kind of monolithic, also can link without ring stand, makes two independent devices respectively, respectively both correspondences is installed in the position of required installation then with a kind of snap ring.

Owing to adopt such scheme, make the more complete convenience of original general theftproof lock, the extensive security insurance of function, it is antitheft that it not only is used to lock car, and the window that can be used to lock a door is antitheft.

Below in conjunction with embodiment the utility model is further described:

Key 8 is to the right rotation core 16 of unblanking among Fig. 2, the platform ladder jack-up return spring 21 in Ra hole 18, separate with Rb hole 18 in Ra hole 18, (Fig. 2 A-A) in vertical state, this moment, the

stop hole

26 and 23 couplings under the pressure of spring 24 of trapezoidal axle of gathering sill 25 1 ends on 17 overlapped in Fig. 2 (B-B) chamber, lock core 16 can not rotate, and key 8 can not be extracted.

Among Fig. 3, dish 9 half-twists tangle, buckling of door bolt thick stick 45 entered in the casket mouth 27, (Fig. 3 B-B) buckles the trapezoidal axle 23 of 5 jack-up, and away from stop hole 26, return spring 21 stretches and makes lock core 16 revolutions, (Fig. 3 A-A) trapezoidal axle 23 puts in place at gathering sill 25 other ends, lock shaft 19 and lock shaft hole 20 corresponding falling in 20 are extracted key, realize automatic blocking.

Among Fig. 4, door bolt thick stick 4 is in the return state, protective case 2 with tangle coil a, the b hole 12 that a coaxial different-diameter is arranged on 9 the end face, b hole built-in spring 14, steel ball 13(Fig. 4 C-C).Remove and change hands handle 3, dish 9 rotations that tangle, the internal chamber wall plane of protective case 2 forces steel ball 13 all to enter in the b hole, and separate with the b hole in a hole; When unblanking, torsion spring 11 makes dish 9 revolutions that tangle, door bolt thick stick 4 returns, and a hole overlaps with the b hole, and the power of spring 14 makes 1/3 of steel ball enter a hole, and 2/3 still in the b hole, thus realization is fastened thick stick 4 with a bolt or latch and ensured public security by stop.
