Description

A kind of head lock

Technical field

The utility model relates to a kind of head lock.

Background technology

Traditional electric control head lock only adopts a secondary electromagnet apparatus to control, its structure comprises electromagnetic coil body and iron core, the front end sleeve of iron core is provided with back-moving spring, this front end also is provided with lock, there is following weak point in existing head lock: 1, Zhuan Zhi safety is not high, and when car body was subjected to external force moment collision, lock was easy to reset, the head lock transient failure is brought opportunity to the thief; 2, because spring is located at the front portion, when driving ifs circuit break down and make the electromagnetic coil dead electricity, iron core ejects with lock because of dead electricity, brings dangerously to driving, very easily gets into an accident.

The utility model content

In order to overcome the deficiencies in the prior art, the utility model provides a kind of rational in infrastructure, safe and reliable head lock.

The technical scheme that the utility model adopted is:

A kind of head lock, comprise lock housing, be provided with the main electromagnet device and the secondary electromagnet apparatus of two orthogonal installations in the described lock housing, the main electromagnet device comprises electromagnetic coil body and iron core, one of iron core is provided with lock, lock stretches out outside the lock housing, the rear portion of electromagnetic coil body is stretched out in the other end of iron core, this extension is arranged with spring, iron core and lock transition position are provided with block, secondary electromagnet apparatus comprises secondary electromagnetic coil body and secondary iron core, and the head of secondary iron core is corresponding to block stretch, contract interstitial site between the stroke, and secondary iron core sleeve is provided with back-moving spring.

Further improvement of the utility model, described lock housing is connected with the mechanical type lock gall, and described lock gall comprises lock gall shell and lock gall core, and the end of lock gall core is stretched in the lock housing, be provided with connecting rod between lock gall core and the secondary iron core, the lock gall core can utilize connecting rod to promote secondary iron core to reset.

Further improvement of the utility model is arranged with lock pin on the described secondary iron core, and mechanical type lock gall connecting rod when work contacts with lock pin and promotes secondary iron core and back resets.

Further improvement of the utility model, described connecting rod is positioned at the bottom of lock.

The beneficial effects of the utility model are: the main electromagnet device and the secondary electromagnet apparatus that are provided with two orthogonal installations in the lock housing, when main electromagnet device control control lock is locked, the secondary iron core of secondary electromagnet apparatus crosses out, lock is located, it can not contracted next time at external force vibration, increased the safety of head lock, anti-theft effect is better; On the other hand, the design is located at the rear portion of electromagnetic coil body with spring, and when unblanking, utilize the tension force of spring that lock is retracted and reset, because electromagnet is in power failure state all the time, thereby the lock maloperation situation that can not occur locking voluntarily, guarantee traffic safety; Further, the design also proposes a kind of electronic, manual dual-purpose direction lock construction, in lock housing is to reserve mechanical type lock gall installation position, lock housing can connect the mechanical type lock gall as required, the user makes the electrical appliance control mode at the Shi Jike that unblanks, also can utilize the lock gall core of mechanical type lock gall promote connecting rod with secondary iron core toward returning back to top, thereby make head lock open, this mechanical lock bladder structure is particluarly suitable for being used for when circuit breaks down emergent unlocking.The design's head lock is rational in infrastructure, anti-theft security height not only, and can not have any impact to traffic safety.

Description of drawings

Below in conjunction with drawings and Examples the utility model is further specified.

Fig. 1 to Fig. 3 is the process of the unblanking schematic diagram of electric control lock;

Fig. 4 is the structural representation that electronic, manual dual-purpose direction is locked;

Fig. 5 is the fundamental diagram that mechanical type is unblanked.

The specific embodiment

Referring to figs. 1 through shown in Figure 3, a kind of head lock, comprise lock housing 1, be provided with the main electromagnet device and the secondary electromagnet apparatus of two orthogonal installations in the lock housing 1, the main electromagnet device comprises electromagnetic coil body 21 and iron core 22, one of iron core 22 is provided with lock 23, lock 23 stretches out outside the lock housing 1, the rear portion of electromagnetic coil body 21 is stretched out in the other end of iron core 22, this extension is arranged with spring 24, and iron core 22 is provided with block 25 with lock 23 transition positions, and secondary electromagnet apparatus comprises secondary electromagnetic coil body 31 and secondary iron core 32, the head of secondary iron core 32 is stretched corresponding to block 25, contract interstitial site between the stroke, secondary iron core 32 is arranged with back-moving spring 33.

Operating principle: when the motorcycle controller being sent when instruction of locking, electrical equipment control system sends earlier following control instruction successively: 1, secondary electromagnetic coil body 31 energisings make secondary iron core 32 withdrawals, as shown in Figure 1; 2, then make electromagnetic coil body 21 energisings, iron core 22 up ejects with lock 23, as shown in Figure 2, vehicle is locked; 3 and then to 31 outages of secondary electromagnetic coil body, the end of secondary iron core 32 extend out to the stroke interstitial site place of stretching, contract of block 25, makes lock 23 not withdraw, and as shown in Figure 3, improves its anti-theft security.
