Description

A kind of theftproof lock

The utility model relates to a kind of lockset, is used for the theftproof lock of vehicles such as automobile, bicycle, power assist vehicle, light roadster, motorcycle.

The structure of the theftproof lock of vehicles such as existing automobile, bicycle, power assist vehicle, light roadster, motorcycle basically all ringwise, its deadly defect be can not prevent effectively that locking pliers from cutting, pick-proof, anti-saw, anti-turning round, the car stealer can achieve the goal with prevailing instrument in a short period of time, and particularly roadster such as bicycle is hard to guard against especially.

The purpose of this utility model provide a kind ofly have that very strong anti-locking pliers is cut, pick-proof, anti-saw, the anti-four anti-locksets of turning round, it is simple in structure, volume is little, can lock turning to of vehicle.

The purpose of this utility model realizes by the following technical solutions: be made up of the iron of riding (1), lock body (2), tapered end (4), lock core (9), lock core card (8) and anti-saw round steel parts such as (10), as shown in drawings.Ride iron (1) and lock body (2) is the main body of lockset, is block structure, and be fixedly connected by pin (3).The tapered end (4) that has dead bolt is housed on the lock body, is useful on the limit pin hole and the movable pin-and-hole that is used to adorn removable pin 6 and little spring (7) of dress spacer pin (5) on the lock body (3), anti-saw round steel (10) also is housed in the lock body.Lock core (9) and lock core card (8) are housed in the tapered end, pagoda spring (12) is housed on the dead bolt step surface of tapered end, a keyway is arranged on the tapered end external cylindrical surface, an end of spacer pin can slide in keyway, shoots the pellet shot from a slingshot hole of son (11) on the tapered end in addition.The iron (1) of riding go up to also have two holding screws (13), fixes after being used for lockset assembled.

The utility model is simple in structure, volume is little, having very strong anti-locking pliers cuts, pick-proof, anti-saw, the anti-performance of turning round, this lockset can lock turning to of vehicle, can prevent that the robber from mentioning that trailing wheel (referring to roadsters such as bicycle) is easily carried out transferring position and calm assistant reduces and prevent the stolen of vehicle from will produce the good social effect effectively.

Accompanying drawing 1 is a structure chart of the present utility model, and accompanying drawing 2 is the sectional drawings at spacer pin and removable pin place.

An embodiment who is used for bicycle theft-prevention below in conjunction with description of drawings the utility model.

The iron (1) of riding is fixedlyed connected with pin (3) with lock body (2), ride between iron and lock body form Φ 35 borehole jack outside the preceding pipe of bicycle, all make with carbon steel, pin (3) is also made with carbon steel, 6 millimeters of diameters, with the hole tight fit on ride iron and the lock body, there is the hole of Φ 20 to be used to adorn tapered end (4) on the lock body (2), tapered end has dead bolt, in the hole before dead bolt can insert on the pipe, lock core (9) and lock core card (8) are housed in the hole of tapered end (4), tapered end and lock core are all made with brass, when before dead bolt inserts, being in locked position in the pore, the position of corresponding lock core card is drilled with limit pin hole and movable pin-and-hole on lock body (2), little spring (7) and removable pin (6) are housed in movable pin-and-hole, little spring turns to 0.5 spring steel wire, removable pin is made step, the spacer pin (5) of Φ 4 is housed in limit pin hole, on the relevant position of tapered end (4), be drilled with stepped hole, be used to adorn removable pin, on the relevant position of spacer pin, on the external cylindrical surface of tapered end (4), be processed with keyway, go up the anti-saw round steel (10) that four Φ 4 are equipped with in the hole of boring four Φ 5 at lock body (2), pagoda spring (12) is housed on the step surface of tapered end upper lock tongue, pagoda spring turns to Φ 1 spring steel wire, on the face of cylinder of tapered end, also be drilled with five pellet shot from a slingshot holes, in order to shoot son, be drilled with the screw of two M6 on the iron 1 of riding, M6 holding screw (13) is housed can be fixed on this lockset on the preceding pipe of bicycle.

The course of work of the present utility model is such:

The utility model is installed in the sleeve pipe or the bicycle of vehicle steering connecting rod, power assist vehicle, light roadster, the outside of pipe before the vehicle body frame of vehicles such as motorcycle, also can directly be welded on sleeve pipe (or preceding pipe) iron of riding (1), before installing earlier with vehicle front-wheel left (or to the right) turn to the bigger steering angle of formation, together bore a hole in the position of sleeve pipe (or preceding pipe) installation lockset together with steering wheel connecting rod (or standpipe) then in sleeve pipe (or preceding pipe) lining, the depth ratio dead bolt extension in hole is dark slightly, load onto lockset, tighten holding screw (13) or with the welding lockset can be installed on the sleeve pipe (or standpipe).

When with key operated lockset, by key lock core (9) is rotated, the front portion that drives lock core card (8) is to the displacement of the outside of tapered end (4), promptly removable pin (6) is pushed in the movable pin-and-hole of lock body, removable pin (6) is pushed away tapered end (4), because the elastic force of pagoda spring (12) is pushed tapered end (4) outside the lock body (2) to, the dead bolt of tapered end (4) promptly withdraws from the boring of steering wheel connecting rod (or standpipe), make steering wheel connecting rod (or standpipe) recover left-right rotation in sleeve pipe (or standpipe), promptly vehicle just can normally use.Afterwards the key revolution is made lock core card (8) homing, and pull out key.

When after stopping, needing locking to turn to, with the position of front-wheel steer to former locking, then tapered end (4) is pushed in the lock body (2), in the boring of the dead bolt of tapered end (4) with regard to direction of insertion dish connecting rod (or standpipe), make it and to rotate, at this moment, because the effect of little spring (7), removable pin (6) is pushed in the hole of tapered end (4), make tapered end (4) also locked, promptly finished the steering locking of vehicle.

The effect of anti-saw round steel (10) be when with the hacksaw desire with lock body (2) when cutting, because of the pulling back and forth of saw blade and when touching anti-saw round steel (10), anti-saw round steel (10) can and then rotate in the hole, make it to be difficult to sawed-off, thereby having guaranteed that lock body (2) exempts from destroys and ineffective, the effect of spacer pin (5) is the shift position that limits tapered end (4), and make tapered end (4) can not break away from lock body (3) also can not rotate, assembling pin (3) combines with the pin-and-hole close-fitting of the iron of riding (1) lock body (2), makes it can't dismantle after assembling.

Claims (2)

1, a kind of lockset of forming by parts such as the iron of riding, lock body, tapered end, lock cores, ride iron and lock body of the main body that it is characterized in that lockset is block structure, fixedly connected by pin, the tapered end that has dead bolt is housed on the lock body, and the effect by dead bolt is with the riser lock of vehicle steering connecting rod or bicycle, power assist vehicle, light roadster, motorcycle.
