Abstract

The utility model discloses an electromagnetic primary and secondary lock, which is characterized in that: the tail end of an arched locking bar is connected with a shell through a rotating shaft; the front end of the locking bar is provided with a lock head; a bolt, a magnet, a coil, a battery, a lock core and a lever are arranged in the shell; the coil is wound at the tail end of the hook-like bolt and is connected to the battery and a switch through wires; the bar magnet is positioned at the right end of the bolt; and the left end of the lever is clamped on the tail part of the bolt, and the right end of the lever is connected with the lock core. The lock is a double insurance lock; the tail part of the bolt is not clamped by the left end of the lever when the lock core is pried by a lawless person, but the iron bolt still locks the lock head under the action of attractive force of the bar magnet at the moment; and only when a tailor-made key is used, the coil is electrified while the lock core is rotated, and the bolt becomes an electromagnet of which the magnetic pole is opposite to that of the bar magnet, and moves leftwards to unlock the lock under the action of repulsive magnetic forces.

Description

A kind of electromagnetism primary and secondary lock

Technical field

The utility model relates to a kind of lock, especially a kind of Lock with double safety guard.

Background technology

Bicycle and electric motor car often will rest in outdoor, for anti-lost, can use lockset, lockset has reduced the loss of personal property effectively, most lock all is mechanical on the market, realize the folding of lock by frame for movements such as springs, this locking make and use all comparatively convenient, if yet meet the lawless person who lockset is had research, mechanical lock is easy to be pried open, the utility model is provided with machinery and electromagnetic structure dual fail-safe, and open method is the same simple with the unlatching common lock when using original-pack key.

Summary of the invention

A kind of electromagnetism primary and secondary lock is characterized in that: the tail end of arch bolt is connected with case by rotating shaft, and the bolt front end is equipped with tapered end, and dead bolt, magnet are housed in the case, coil, battery, lock core, lever; The end of hook-shaped dead bolt is wound with coil, and coil is connected on battery and the switch by lead, and bar magnet is positioned at the right-hand member of dead bolt, and the lever left end is stuck in the dead bolt afterbody, and lever right-hand member and lock core join.The utility model is a kind of double-protection lock set, when lock core is pried open by the lawless person, can only remove the blocking of lever left end to the dead bolt afterbody, and at this moment, the irony dead bolt still pins tapered end under the attraction of bar magnet; Have only and use special key, allow coil electricity, dead bolt become electromagnet and opposite with the bar magnet magnetic pole in the time of rotational lock core, dead bolt is moved to the left to finish under the effect that magnetic force repels each other and unblanks.

Beneficial effect: when the utility model is realized the lockset dual fail-safe, kept it and had the ease of use of common lockset, promptly safety is convenient again.

Description of drawings

Fig. 1 is a kind of electromagnetism primary and secondary lock of the utility model example structural representation.

Fig. 2 is that the utility model example is pried open the effect schematic diagram.

Fig. 3 is the utility model effect schematic diagram of normally unblanking.

The specific embodiment

The explanation of mark among Fig. 1: bolt 1, tapered end 2, case 3, dead bolt 4, coil 5, magnet 6, battery 7, switch 8, lock core 9, lever 10.

A kind of electromagnetism primary and secondary lock shown in Figure 1, the tail end of arch bolt 1 is connected with case 3 by rotating shaft, and bolt 1 front end is equipped with tapered end 2, and dead bolt 4 is housed in the case 3, coil 5, magnet 6, battery 7, switch 8, lock core 9, lever 10; The end of hook-shaped dead bolt 4 is wound with coil 5, and coil 5 is connected on battery 7 and the switch 8 by lead, and bar magnet 6 is positioned at the right-hand member of dead bolt 4, and lever 10 left ends are stuck in dead bolt 4 afterbodys, and lever 10 right-hand members and lock core 9 join.

Referring to Fig. 1, the utility model is a double-protection lock set, and during pinning, dead bolt 4 moves right under the polarity of magnet 6 and blocks tapered end 2, becomes the insurance of first road; The left end of lever 10 blocks the afterbody of dead bolt 4, becomes the insurance of second road.

Referring to Fig. 2, if this lockset is prized lock core 9 by the lawless person, the rotation of lock core 9, drive lever 10 left ends lift and no longer block dead bolt 4, but only removed insurance together this moment, dead bolt 4 still blocks tapered end under the polarity effect of magnet 6, guaranteed that lockset is not opened.

Referring to Fig. 3, use special original-pack key to open, when lever 10 left ends lifted, coil 5 energising made dead bolt 4 become electromagnet and produces repulsion with bar magnet 6, and dead bolt 4 is moved to left, and has removed the twice insurance, opens lockset.

Claims

1. electromagnetism primary and secondary lock, it is characterized in that: the tail end of arch bolt is connected with case by rotating shaft, and the bolt front end is equipped with tapered end, and dead bolt, magnet are housed in the case, coil, battery, lock core, lever; The end of hook-shaped dead bolt is wound with coil, and coil is connected on battery and the switch by lead, and bar magnet is positioned at the right-hand member of dead bolt, and the lever left end is stuck in the dead bolt afterbody, and lever right-hand member and lock core join.
