Description

Magnetic card handcuffs

Technical field

The utility model relates to a kind of handcuffss, specifically is a kind of anti-Magnetic card handcuffs of dialling the anti-prying performance that has.

Background technology

At present, domesticly all adopt a kind of traditional frame for movement handcuffss, it mainly utilizes gear or the manufacturing of ratchet principle, and both hands or one hand with criminal during use handcuff, its product structure heaviness, it is relatively poor to draw materials, principle is single, and shaped as key bit is directly perceived, is chosen out by foreign matter easily, often cause malfunctioningly, that can not play the instrument of torture well should have effect.

Summary of the invention

The purpose of this utility model is at the deficiencies in the prior art, adopts magnetic technique and rational frame for movement, and a kind of anti-Magnetic card handcuffs of dialling the anti-prying superior performance is provided.

The technical solution of the utility model is as follows:

Magnetic card handcuffs of the present utility model is made of rotating ring, basic ring, lock core base, unlocking link, bumper bar, ratchet, flat spring, chain, wherein rotating ring is connected by pin with basic ring, two corresponding magnetic pins are arranged in the middle of the lock core base, there is unlocking link the lock core base outer ring, two teeth are arranged on the unlocking link, engage with ratchet, bumper bar respectively, bumper bar matches with flat spring, there is the insurance push rod bumper bar end, on the corresponding magnetic card key two magnetic pins that repel each other is arranged.

Before magnetic card key of the present utility model did not insert, two magnetic pins were inhaled mutually in the handcuffss lock core base, lock core base and unlocking link be in " from " state; After magnetic card key inserts, there are a magnetic pin and magnetic card key to repel each other in the two magnetic pins, lock core base and unlocking link are in the state of " closing ", when magnetic card key clockwise rotates, push bumper bar open and undo the lock, when magnetic card key rotates counterclockwise, lock core base restores, and bumper bar is motionless.

The utility model has improved the anti-anti-prying performance of dialling owing to adopted magnetic technique and rational frame for movement; In magnetic card key inserts and rotates, draw back bumper bar and unblank to link on the other hand and finish; Owing in the magnetic card key two magnetic pins that repel each other are arranged, after magnetic card key inserts from different directions, must there be a magnetic pin and magnetic card key to repel each other in the two magnetic pins, easily open handcuffss.

The specific embodiment

As shown in Figure 1, 2, a kind of Magnetic card handcuffs, constitute by rotating ring 10, basic ring 11, lock core base 2, unlocking link 4, bumper bar 8, ratchet 9, flat spring 12, chain 14, wherein rotating ring 10 is connected by pin 7 with basic ring 11, two corresponding magnetic pins 3 are arranged in the middle of the lock core base 2, there is unlocking link 4 lock core base 2 outer rings, two teeth 5,6 are arranged on the unlocking link 4, engage with ratchet 9, bumper bar 8 respectively, bumper bar 8 matches with flat spring 12, there is insurance push rod 13 bumper bar 8 ends, on the corresponding magnetic card key 1 two magnetic pins 15 (as shown in Figure 4) that repel each other are arranged.

As shown in Figure 3, before magnetic card key 1 of the present utility model did not insert, two magnetic pins 3 were inhaled mutually in the handcuffss lock core base 2, lock core base 2 be in unlocking link 4 " from " state.

As shown in Figure 4, when magnetic card key 1 inserts lock core base 2, because the effect of magnetic force, there is a magnetic pin to release in the lock core base in the magnetic pin 3 from radial direction, lock core base 2 is integrated with unlocking link 4 constipations, key subsequently, and two teeth 5,6 on the unlocking link 4 just successively promote its binding site, wherein tooth 5 promotes the A portion of bumper bars, the end that ratchet has tooth is mentioned by the B portion that tooth 6 promotes ratchet 9, and lock is opened, the rotating ring 10 of handcuffss is promptly deviate from from basic ring 11, is resetted by flat spring 12.After insurance push rod 13 advanced, bumper bar was pushed down ratchet and is locked at once, and can prevent to choose out with foreign matter.
