Background technique

Cartridge metal handcuffs, which are widely used throughout the world, use a common triangular key and can be illegally unlocked using simple tools such as large pins, nails, bamboo sticks, and paper that can be found anywhere. As a result, there has been frequent escalation of surveillance worldwide, and the reliability of existing metal handcuffs has been seriously questioned.

Announced on November 16, 2011, the announcement number CN102364018A, announced a patented "anti-spring lock" patent technology in the inventor's application, providing a lock body with a marble hole composed of upper and lower semicircles, a lock cylinder The marble hole is a non-spring lock of a round hole. The unspringd lock is used to modify the existing metal handcuffs, and the modified tubular metal handcuff lock cylinder is a rotating structure.

Announced on February 22, 2012, Announcement No. CN102359312A, another patented "anti-spring lock" patented by the inventor of the present invention is disclosed, which provides a lock body and a lock core with bullet holes which are concentric holes. The springless bullet lock.

The disadvantages of CN102364018A and CN102359312A are that neither of the magnetic marbles are mentioned nor used, the key post teeth on one side serve as the unlocking coded teeth, and the key cylinder teeth on the other side are the thrust columns that push the marbles toward the unlocking coded column teeth (instead of the action of the springs) ), there is a defect that only one-sided coding can be realized, the key amount of the lock is small (the combination of the bullet coding is simple), and the mutual opening rate is high. At the same time, the specific structure of the tubular metal handcuff provided by the present invention is not mentioned.

Summary of the invention

The object of the present invention is to provide a tubular metal handcuff, in particular, a push-pull lock with a large amount of keys (which can be coded on both sides), which must be opened simultaneously using two keys, and using magnetic balls of opposite polarity and mutual exclusion. High reliability tubular metal handcuffs with core structure. The technical solution of the present invention is:

A tubular metal handcuff, including a body, a gear, a shaft, a pawl, a telescopic pin, an operating handle, a lock pin, a lock body, a cylinder, a joint, a lock cylinder, a marble, a spring, a fan beam, a rivet, a key A , the key B and the positioning pin member; the cylinder has a slit, a positioning pin hole, a chute, a column perforation and a tail hole; the body is welded to the barrel, the fan beam and the body are riveted by a rivet; the gear is assembled through the shaft In the gap of the lock body, the lock body is sleeved into the cylinder body and positioned by the positioning pin, and the lock core is located in the lock core slot of the lock body; the pawl of the invention has a braking surface, a flat pressing surface, a telescopic groove, a telescopic tail and a spring The lock cylinder has a telescopic pin hole, a shank groove, a shank pin hole, an anti-locking pin hole and an anti-locking pin hole; the lock body has a slit, a shaft hole, a lock cylinder groove, a chute, an anti-locking pin hole, an anti-locking pin hole and a positioning Pin hole; the handle has a handle cap, a stem and a pin hole;

The telescopic tail of the pawl of the present invention is embedded in the telescopic slot of the lock cylinder, the spring trap of the pawl and the spring trap of the lock cylinder have a spring therein, and the telescopic pin hole of the lock cylinder and the telescopic slot of the pawl are equipped with a telescopic pin; The shank passes through the sliding groove of the cylinder and the sliding groove of the lock body, and extends into the bottom of the lock shank; the shank hole of the lock cylinder and the pin hole of the operating handle penetrate through the lock shank.

In the anti-locking state, the spring is relaxed, the gear applies a force from the flat pressing surface of the pawl, and the pressing pawl moves to the right, and the fan beam can rotate counterclockwise; but the gear applies force from the braking surface of the pawl, the pawl No lateral movement will be done, thus achieving a working mode in which the fan beam can only be tight and not loose.

In the anti-locking state, the spring is pressed, and the left end surface of the lock cylinder is pressed against the pawl. When the gear is applied from the flat pressing surface or the braking surface, the pawl does not generate displacement, and the fan beam cannot rotate in any direction. Thereby implementing the function of the anti-lock bit.

In the open state, the pawl is moved to the right by the telescopic pin of the lock cylinder, completely separated from the gear, and the fan beam can be freely rotated in any direction, thereby realizing the opening function.

The same anti-locking pin hole and the anti-locking ball hole of the lock core of the present invention are provided with at least two magnetic balls which are opposite in polarity and mutually repulsive.

The invention utilizes the repulsive force between the magnetic balls which are opposite in polarity and mutually repulsive, which is equivalent to adding a spring between the two marbles, so that the marbles on both sides can always be separated from the two sides without inserting the key. The interface across the lock body and the lock cylinder prevents the relative sliding between the lock cylinder and the lock body from locking.

In the same marble channel of the present invention, in addition to the middle two marbles, the outer marbles also have better magnetic marble effect, and the double-keyed cylindrical teeth can be arranged on both sides to unlock the marbles, and the key amount of the lock is extremely large, even if Professionals with lock structures are also difficult to turn on without key technology. The center distance between the cylindrical perforations of the cylinder of the present invention is L; the center distance between the anti-locking bullet holes of the lock body is L, and the center distance between the anti-locking bullet holes and the adjacent anti-locking marble holes is 2L; The center distance between the core anti-locking bullet holes is L, the center distance between the anti-locking pin holes and the adjacent anti-locking pin holes is J, and L < J < 2L.

The cylindrical perforations of the barrel of the present invention correspond to the center of the anti-locking bullet holes and the anti-locking bullet holes of the lock body.

The center of the anti-locking pin hole of the lock cylinder of the invention is corresponding to the center of the anti-locking pin hole of the lock body when the handcuff is in the anti-locking position state, and the center of the anti-locking pin hole of the lock core and the center of the anti-locking pin hole of the lock body are dislocated (as shown in FIG. 3). Show).

The center of the anti-locking pin hole of the lock cylinder of the invention is in the anti-lock state of the hand lock, and is offset from the center of the anti-locking pin hole of the lock body, and the center of the anti-lock pin hole of the lock core corresponds to the center of the anti-lock ball hole of the lock body (as shown in FIG. 1 ). ).

In the anti-locking position of the lock cylinder of the invention, the center of the anti-locking bullet hole is completely misaligned with the anti-locking position of the lock body and the center of the anti-locking bullet hole when the handcuff is open (as shown in FIG. 2).

The invention has at least one anti-locking pin hole. When there are two or more anti-locking pin holes, the center distance between the adjacent anti-locking pin holes is L.

The working process of the invention:

The default position of the lock cylinder of the present invention is an anti-lock state, that is, the hand-cranked fan beam can only rotate counterclockwise, and cannot

Rotate clockwise (only tight, not loose), the marble in the anti-locking bullet hole straddles the interface between the lock cylinder and the lock body, and the middle two marbles in the anti-locking bullet hole are constrained in the lock cylinder.

Inserting the keys on both sides, the inner end faces of all the marbles on both sides of the lock body are adjusted by the cylindrical teeth to the interface between the lock body and the lock core, and the operation handle is pushed to the left side, and the lock core and the anti-locking position of the lock body correspond to the center of the marble hole. The marbles straddle the interface between the lock cylinder and the lock body, the spring is compressed, the lock core holds the pawl, the key is pulled out, the gear cannot rotate, the fan beam can no longer rotate in any direction, and the handcuff is reversely locked.

Insert the key on both sides and push the handle to the right, so that the marbles in the lock cylinder are all restrained in the lock cylinder. The pawl is separated from the gear, and the key is extracted to open the hand.

The advantages of the invention are:

1. The unlocking marbles can be arranged on both sides separately, and the key amount is large. Even if the technician who unlocks the structure can not be illegally unlocked, it can be used to manufacture high-reliability metal handcuffs, effectively preventing or reducing the occurrence of supervisory escape events. 2, according to user needs to configure a special key, a change in the global cartridge handcuffs a key situation.

3. By using the repulsive force between the magnetic cylinders with opposite polarity and mutual exclusion, instead of the spring between the two marbles, the volume of the lock can be made smaller.
