Abstract
The utility model relates to handcuffs, which are composed of a handcuff body, a tube support, a fan beam, a lock core, a lock core seat, a cam and a gear, wherein, two magnetic pins are arranged in the lock core seat, the outer edges of the magnetic pins are check rings, the fan beam is engaged with the gear, and the gear is controlled by the cam. Before a magnetic card key is inserted, the two magnetic pins repel each other and the lock core seat are in off state; after the magnetic card key is inserted, the two magnetic pins attract each other and the lock core seat is in a closed state. Turning the key in a clockwise direction, the handcuffs are unlocked, and turning the key in an anticlockwise direction, the handcuffs are secured. The utility model which adopts a cylindrical structure and combines advanced magnetic technique is solid and firm with beautiful appearance.
Description
The utility model relates to a kind of handcuffss, particularly a kind of drum type brake Magnetic card handcuffs.
At present, domesticly all adopt mechanical metal handcuffss, it utilizes gear or ratchet principle, and is directly perceived because of the shaped as key bit that it adopted, and the member of unblanking is direct, is chosen out by foreign matter easily, causes handcuffss malfunctioning, can not play the due effect of a kind of implement of police.And several board-like Magnetic card handcuffs (power has patented) of our company exploitation prove that anti-the choosing of Magnetic card handcuffs prevent that group performance is better than traditional frame for movement handcuffss greatly, but the certain limitation of board-like handcuffss product structure band.
The purpose of this utility model is at the deficiencies in the prior art, and a kind of good looking appearance is provided, and sound construction has the anti-superior drum type brake Magnetic card handcuffs of safety performance of choosing.
The utility model is realized with following form:
The utility model is made of handcuffs body, tube frame, fan beam, lock core, lock core base, cam and gear, and lock core, lock core base, cam, gear are installed in the tube frame of cylinder, and two magnetic pins are installed in the lock core base, and there is back-up ring magnetic pin outer; The fan beam is meshed with gear, and gear matches with cam, has skewed slot to match with the steel pin of lock core base bottom on the cam.
When the utility model did not insert at magnetic card key, two magnetic pins repelled each other, and were held by handcuffs body metal cylinder, lock core and lock core base be in " from " state, when magnetic card key insertion lock core, two magnetic pins are inhaled mutually, lock core and lock core base are in the state of " closing "; Magnetic card key undoes the lock after the arming when clockwise rotating, and when rotating counterclockwise, the lock core assembly resets, and safety lock after the safety lock, can prevent that foreign matter from choosing out from slot.
The utility model adopts advanced magnetic technique, has improved the anti-safety performance of choosing, and adopts cylinder mode, and product is solid firmly, and long-term the use is not yielding, good looking appearance, and the entire product profile is all used circular curve, connects smoothly, and good hand touch can't harm the criminal of being tortured.
Accompanying drawing 1 is the utility model outline drawing.
Accompanying drawing 2 is a utility model M-M sectional view.
Accompanying drawing 3 is the utility model schematic diagram.
Accompanying drawing 4 does not insert state diagram for magnetic card.
Accompanying drawing 5 inserts the back state diagram for magnetic card.
Below in conjunction with accompanying drawing the utility model embodiment is done-elaborates.
As shown in Figure 1, 2, 3, the utility model is made of handcuffs body (11), fan beam (12), tube frame (10), chain button (2), lock core (3), lock core base (6), cam (7), gear (9), lock core (3), lock core base (6), cam (7), gear (9) are installed in the frame (10), two magnetic pins (4) are installed in the lock core base (6), and there is back-up ring (5) magnetic pin (4) outer; Fan beam (12) is meshed with gear (9), and gear (9) matches with cam (7), in the bottom of cam (7) a tooth E is arranged, and tooth E and gear (9) are meshed; Special skewed slot D is arranged on the cam (7), and steel pin C is equipped with in lock core base (6) bottom, between cam (7) and the lock core base (6) stage clip (8) is arranged.
The utility model fan beam (12) is formed by the involute profile curve with the field of conjugate action of gear (9), and gear (9) is by cam (7) control, and it has three kinds of forms of motion: a, one-way movement; B, freely-movable; C, slack.Handcuffss in use require fan beam (12) to go into the i.e. lock in position, and gear (9) is in the one-directional rotation position, finishes the principle of only advancing not move back, and when unblanking, gear (9) is in free turned position, and fan beam (12) can be by withdrawing from (or entering) in the handcuffs body; When gear (9) was slack, handcuffss were in safety position, and fan beam (12) is locked motionless.
When the utility model steel pin C rotates, can make cam (7) rise, descend or stop.Because the effect of stage clip (8), the tooth E and the gear (9) of cam (7) bottom all are in engagement, and tooth E comes three kinds of motions of control gear (9) according to the characteristics of motion of cam (7).
As shown in Figure 4, when magnetic card key (1) did not insert lock core (3), two magnetic pins (4) repelled each other, lock core (3) and lock core base (6) be in " from " state.
As shown in Figure 5, when magnetic card key (1) inserts lock core (3), and the square tenon B that makes its end enters and puts in place, during the key of whipping, owing to be embedded in the effect of magnetic sheet A in the key cylinder, two magnetic pins (4) are inhaled mutually, originally be contained in the lock core base (6) the magnetic pin half enter lock core (3), lock core (3) and lock core base (6) are linked together, and thus, lock core (3) and lock core base (6) are in the state of " closing ".
When above-mentioned situation, the moment of magnetic card key (1) can pass to steel pin C, and by the motion that cam (7) removes control fan beam (12), makes handcuffss obtain to open, and closes or locking.
Claims (3)
