Abstract

The utility model discloses a novel anti-theft lock which belongs to the field of the anti-theft lock manufacturing technology. The novel anti-theft lock comprises a lock body, two conducting cylinders are connected on the upside and the underside of the locking hole of the lock body; a lock core is installed in the locking hole; two conducting cylinders are connected on the lock core; the two conducting cylinders on the locking hole are connected in a circuit in series; the circuit is arranged in the lock body; the switch of the circuit is commonly formed by the two conducting cylinders on the lock hole and the two conducting cylinders on the connected and disconnected lock core; an electromagnet is connected on the circuit in series; and the electromagnet is connected with a metal locking rod inserted in a wheel. When an electromagnet relay in the circuit works to suck out the metal locking rod, the wheel can rotate. The utility model has the advantages of rational design and safe use, and the like.

Description

Novel anti-burglar lock

Technical field

The utility model discloses a kind of novel anti-burglar lock, belongs to anti-theft column lock class manufacturing technology field.

Background technology

Motorcycle anti-theft is that producer and user want a thorny problem solving for a long time, and this problem does not also solve well, and this also is the problem that our difficulty facing and needing solves.The mechanical type lock that arrives commonly used at present can not well be protected motor bike.

Summary of the invention

At the deficiencies in the prior art, the utility model provides a kind of novel anti-burglar lock reasonable in design, safe in utilization.

The utility model is achieved through the following technical solutions:

The utility model comprises lock body, wherein: the lockhole of described lock body is connected to two conductor pins in both sides up and down, lock core is housed in the lockhole, be connected to two conductor pins on the lock core, two conductor pins on the lockhole are connected in the circuit, and this circuit is arranged in the lock body, the switch of two common built-up circuits of conductor pin on two conductor pins on the lockhole and the lock core that switches on and off, be in series with electromagnet on circuit, electromagnet is connected with metal locking bar in being inserted in wheel.

One electromagnetic relay is arranged in the utility model circuit, and the metal locking bar inserts in the axletree when no current passes through, and wheel can not be rotated; Electromagnetic relay work is extracted the metal locking bar out axletree when electric current passes through, and wheel can rotate.Key hole is horizontal when engine off, make two conductor pin a on the lock core, two conductor pin c on b and the lockhole, d can not link together, can not constitute the loop, key hole is vertical when starting car with key, makes a, b and c, d connects and constitutes the loop, electromagnetic relay work is with the sucking-off of metal locking bar, and wheel just can rotate, and has advantages such as reasonable in design, safe in utilization.

Description of drawings

Fig. 1 is the utility model first status circuit constructional drawing;

Fig. 2 is the utility model second status circuit constructional drawing.

Wherein, 1 is electromagnet, and 2 is power supply, and 3 is lock core, and 4 is axletree.

The specific embodiment

Embodiment: structure as shown in Figure 1 and Figure 2, the utility model comprises lock body, wherein: the lockhole of described lock body is connected to two conductor pins in both sides up and down, lock core 3 is housed in the lockhole, be connected to two conductor pins on the lock core, two conductor pins on the lockhole are connected in the circuit, this circuit is arranged in the lock body, the switch of two common built-up circuits of conductor pin on two conductor pins on the lockhole and the lock core that switches on and off, be in series with electromagnet 1 and power supply 2 on circuit, electromagnet is connected with metal locking bar in being inserted in axletree 4.

Lockhole is two conductor pin c of two side joints up and down, d, and connecting when two ends is to constitute a complete circuit (Fig. 2), key hole and c, the vertical both sides of d are with two conductor pin a, and b is connected on (shown in Figure 1) on the key hole.One electromagnetic relay is wherein arranged in the circuit, when no current by the time have in the electromagnetic relay iron bar to insert in the wheel lock, wheel can not be rotated; As electric current by the time electromagnetic relay work will extract axletree out with the iron bar of its one, wheel can rotate.Key hole is horizontal when engine off, makes a, and b and c, d can not link together to go on foot and can constitute the loop, and key hole is vertical when starting car with key, makes a, and b and c, d connect and constitute the loop, and electromagnetic relay work can be moved iron bar sucking-off car.

A as shown in Figure 1, b is connected on the lock core, and lockhole changes when opening the lock with the key, and makes a, b and c, d joins as Fig. 2.Wherein with a, the place that b overlaps is that a groove makes a, and it is short-circuit condition all the time that b can not link to each other with lock body when rotating, when forwarding to can open driving engine the time and c, and circuit debugging when d collides.Major advantage of the present invention: can prevent by actv. stolen, even the robber opens driving engine without the key car can not walk.

Claims

1, novel anti-burglar lock, comprise lock body, it is characterized in that: the lockhole of described lock body is connected to two conductor pins in both sides up and down, lock core is housed in the lockhole, is connected to two conductor pins on the lock core, two conductor pins on the lockhole are connected in the circuit, this circuit is arranged in the lock body, the switch of two common built-up circuits of conductor pin on two conductor pins on the lockhole and the lock core that switches on and off is in series with electromagnet on circuit, electromagnet is connected with metal locking bar in being inserted in wheel.
