Detailed Description

The utility model is further explained with the following drawings: as shown in the figure, the police handcuffs comprise a lock cylinder seat 1, wherein a base ring 2 is arranged on the lock cylinder seat, a hinged movable ring 3 is arranged on the base ring, a ratchet 31 is arranged on the movable ring, a lock plate 4 which is in one-way fit with the ratchet is hinged in the lock cylinder seat, a first elastic piece 5 is in sliding fit in the lock cylinder seat, a safety piece 6 which is in linkage fit is arranged on the first elastic piece, the lower end of the safety piece extends to the lower part of the lock plate and is provided with a stop block 62, a first groove 11 and a second groove 12 are arranged in the lock cylinder seat, a convex block 61 is arranged at the upper end of the safety piece, and the safety piece comprises a first position where the convex block falls into the first groove and the stop block is in abutting press fit with the bottom of the lock plate; and a second position in which the projection falls into the second slot and the stop is clear of the lock plate.

During the use, when the lug of insurant falls into first groove, this dog is supported press fit with the jam plate bottom, make the jam plate can not rotate like this, just make the unable anticlockwise (as shown in figure 1) rotation of one-way complex rotating ring, after insurant atress activity right, this lug falls into the second inslot on right side, the dog also moves right, make the jam plate can anticlockwise rotate, no longer block the rotating ring, the handcuffss can be opened, need explain, only include a handcuffss in the description drawing, be two handcuffss in the use, rethread chain or other connecting pieces connect, for prior art, no longer describe repeatedly.

In this embodiment, as shown in the figure, the first elastic member is a cylindrical spring. And a tower-shaped spring and the like can be adopted, so that the using effect is better.

In this embodiment, as shown in the figure, the cylinder seat is provided with a first hole 13 and a second hole 14 for inserting a key, and the first hole and the second hole are correspondingly arranged on two sides of the first elastic element. When the lock needs to be unlocked, the key extends into the first hole to rotate so as to drive the first elastic piece to move rightwards to unlock, and when the lock needs to be locked, the key is inserted into the second hole to push the first elastic piece to move leftwards.

In this embodiment, as shown in the figure, a second elastic element 15 is further disposed in the lock cylinder seat, and the lock plate includes a lock head 41, and the second elastic element pushes the lock plate to make the lock head and the ratchet cooperate in a single direction. The tapered end is right triangle, and its hypotenuse is outwards, and the right-angle side is inwards, and when the rotating ring clockwise rotated, can push away the jam plate (if the dog is not when blockking the jam plate), if when the rotating ring anticlockwise rotated, the jam plate can support and press and can't rotate at the lock core seat inner wall, realizes one-way spacing.

In this embodiment, as shown in the figure, the second elastic member is a torsion spring, the torsion spring includes a first torsion leg and a second torsion leg 151, the second torsion leg presses against the back of the lock plate, and the first torsion leg presses against the inner wall of the lock cylinder seat. Through second elastic component location jam plate, provide the pretension, it is more convenient to use, prevents to stir.

In this embodiment, as shown in the figure, the inner wall of the lock cylinder seat is provided with a blocking wall 17, and the front end of the lock plate is arranged corresponding to the blocking wall.

In this embodiment, the stopper is bent into a circular shape as shown in the figure, and the stopper is provided with a pin 621 therein.

In this embodiment, as shown in the figure, the bottom of the locking plate is provided with an avoiding groove 42 corresponding to the stopper. When the safety piece is in the second position, the lock plate is convenient to rotate.

In this embodiment, as shown in the figure, the safety element is bent to form a limiting groove 63, the bottom of the cylindrical spring is in sliding fit with the bottom of the inner wall of the lock cylinder seat, and the upper end of the cylindrical spring is arranged in the limiting groove. As the preferred, the cylindricality spring bottom is the plane, and the spacing inslot is located to the upper end, prevents to rock, and the result of use is better.
