Abstract

The utility model provides a full-closed anti-theft safety bicycle lock, which is very suitable to be mounted on handlebar shaft of bicycle, electric bicycle and pedicab to lock the handlebar shaft and is especially suitable to be mounted as the bicycle is manufactured by bicycle producer and more convenient for users. The utility model comprises a nut arranged on the axle and a lock shell with a lock core and a locking mechanism, with the nut and the lock shell integrated. The locking mechanism is connected with the poking block, which is connected with the lock core, by a check lock lever, a sliding cassette with a ball bearing retained on the fork mounting shaft and a locking disk riveted to fix the cassette. The whole lock body is in a fully closed and completely hidden state. In operation, the key drives the lock core to rotate clockwise or anticlockwise, the poking block connected with the lock core drives the check lock lever to move up and down to insert into or withdraw out of the blind hole in the fixed cassette, thereby achieving the goal of locking the axle and avoiding theft.

Description

Totally-enclosed burglary insurance lock

Technical field

The utility model relates to a kind of anti-theft vehicle lock, suits especially to install on bicycle, Electrical Bicycle, three-wheel vehicle handlebar axis, is used for the totally-enclosed burglary insurance lock that the lock handle axle uses.

Background technology

Existing anti-theft lock for bicycle is various in style, but outside most lock bodies all is exposed to, so be easy to be prized, sawed, pounded, use dangerous, theftproof performance is poor, the patent No. 89217937.6 " Lock adapted for bicycles ", 92206287.0 " the directed anti-theft column lock of handle-bar " is though also provide the anti-theft column lock that is used to lock tap, but because of it is not the fully enclosed, thus also exist theftproof performance poor, use unsafe drawback.

Summary of the invention

Technical problem to be solved in the utility model is, provides a kind of and do not take available space but easy to use, safe, and the good totally-enclosed burglary insurance lock of theftproof performance.

The technical scheme that the utility model technical solution problem is adopted is: totally-enclosed burglary insurance lock connects into integral body with the lock housing that lock core, catch gear be installed and constitutes by being installed in nut on the handle axle, described catch gear by the sliding clip, R-clip that ball are arranged with lock core bonded assembly shifting block by clamping on locking lever and the car crotch axle with and the locking plate that is fixed into of cap be connected, cooperate constitute.

Compared with prior art, advantage of the present utility model is: this whole lock body all is in totally-enclosed, complete hidden state, and a lockhole can only be seen in the outside, thus do not subject to the destruction of pounding, saw, prizing, therefore safe in utilization, theftproof performance good.

This lock construction is simple in addition, optimum bicycle manufacturer produces and uses, so part of lock, only need the original part of bicycle is just made improvements slightly and can utilize, some part again can be general with bicycle, thereby low cost of manufacture, volume are little, do not take available space again, and Bicycle Plant can install and dispatch from the factory.The lock of needn't bending over to open and close during use, cleaning, more convenient user uses.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Handle axle (1), nut (2), Hanging Basket support (4), ball (12), car crotch axle (14), triangle gear shaft (15) and cap (9) all are the part on the former bicycle, for preventing that rainwater from entering in the lock, on nut (2) inwall, increase the groove of a placement seal ring (3).

Lock housing (5) is a cylindrical shape, and there is outside thread the upper end, and there is negative thread the lower end, and a hole of button that protrudes is arranged on the sidewall, and the gusset of two vertical band chutes is arranged on the inwall of hole of button and lock housing junction.In chute, connect a baffle plate (8).

Lock core (6) is installed in hole of button, and lock core (6) end stretches in the baffle plate (8), and the shifting block (7) that rotates together at its end fixed random lock core (6).

Locking lever (10) lower end is two cylindrical bars, and the upper end is the curvilinear figure that cooperates with shifting block (7), and its edge fixing spring (16) plays locking action.

Sliding clip (11) is for there is screw the centre, and there is screw thread the neighboring, and periphery has the disc of uniform 8-12 the through hole that cooperates with locking lever (10), promptly increases 8-12 through hole and use on the former part of bicycle.

R-clip (13) has a groove for there are through hole, through hole limit in the centre, and there is screw thread the neighboring, and the upper surface periphery has the T shape of a uniform 8-12 blind hole, and, cooperation corresponding with sliding clip (11), promptly increases 8-12 blind hole and use on the former part of bicycle.

During installation, the nut (2) of need outwarding winding is taken away handle and is exposed handle axle (1), with R-clip (13) gripping sleeve on car crotch axle (14), put ball (12) and sliding clip (11) again, and with and cap (9) be fixed into locking plate, and utilize the screw thread on it to be fixed on the car crotch axle (14), to install lock core (6) again, shifting block (7), locking lever (10), the lock housing (5) of baffle plate (8), be enclosed within sliding clip (11), outside the R-clip (13), and captive joint with sliding clip (11) with screw thread on it, put Hanging Basket support (4), nut (2) locking with band seal ring (3), totally-enclosed burglary insurance lock is assembled into, and at last handle is fixed on handle axle (1) end.

During use, insert lock core (6) and anticlockwise motion with key, by the terminal shifting block (7) of lock core (6), stirring locking lever (10) moves down it, and with in the blind hole on the two cylindrical bars reeve R-clips (13) of lower end, thereby lock handle axle (1) can not rotate it, just can extract key.

If need to use car, but the clockwise direction key, shifting block (7) is dialled locking lever (10) and is returned to original position from the blind hole of R-clip (13), and bicycle just can use.

Or handle axle (1) clockwise direction is rotated an angle without key, with shifting block (7) locking lever (10) is extracted from the blind hole of R-clip (13).
