Detailed ways

Below in conjunction with accompanying drawing, the utility model is described in further detail:

Referring to Fig. 1 and Fig. 2, the utility model remote control manual combined anti-theft lock includes a cavity 1 sleeved on the direction axis 2, a power supply 3 installed in the cavity 1, a normally closed switch 4 connected to the power supply 3 and a circuit The control board 5, the motor 6 connected with the circuit control board 5 and the alarm horn 14, and the dead bolt 7, one end of the dead bolt 7 arranged horizontally is matched with the locking tooth 8 fixed on the direction shaft 2, the locking tooth There are multiple grooves on it; the other end corresponds to the normally closed switch 4 fixed on the side wall of the cavity 1, and is in dynamic contact with the normally closed switch 4; the upper surface of the dead bolt 7 is provided with a linkage gear 9 Cooperating ratchet part, a spring 10 set on the deadbolt 7 is arranged between one end surface of the ratchet part and the direction shaft; The ratchets are matched, and the push shaft 11 passes through the bottom plate of the cavity 1 and can be stretched outside the cavity; the lower surface of the dead bolt 7 is also provided with a slot 13 that matches the pin rod 12, and the pin rod 14 Driven by motor 6 for linear reciprocating motion.

The working principle of the present utility model is: when in the unlocked state, the dead bolt 7 is in contact with the normally closed switch 4, the normally closed switch 4 is in an open state, the circuit control board 5 does not control the motor 6, the motor 6 is in a non-working state, and the hand push shaft 11 Stretch out of the cavity; when locking, press the hand push shaft 11 by external force, the hand push shaft 11 drives the linkage gear 9, and then drives the lock tongue 7 to move to the right so that the lock tongue 7 is inserted into the groove of the lock tooth 8, and the direction shaft 2 is locked. Locking; at the same time, the dead bolt 7 is separated from the normally closed switch 4; the normally closed switch 4 is in a closed state, the circuit control board 5 controls the motor 6 to rotate forward, and the pin rod 12 is inserted into the draw-in groove 13 of the dead bolt 7; through the circuit The setting of control board 5, motor 6 stops working after working 3 seconds, then the utility model is in locked state, if any criminal destroys the utility model, then alarm horn 14 sends alarm sound, frightens off the car thief; Unlock , by pressing the remote controller, the remote controller controls the circuit control board 5, and the circuit control board 6 controls the motor 6 to reversely rotate, and the pin bar 12 is withdrawn from the draw-in groove 13, and the dead bolt 7 is reset under the action of the spring 10 at the same time. Contact with the normally closed switch 4, so that the motor 6 is in the non-working state again, and the hand push shaft 11 withdraws from the cavity 1 to realize unlocking.

The motor 6 of the present utility model can also be realized by a solenoid valve, and the insertion and withdrawal of the pin rod 12 into and out of the draw-in slot 13 are realized by powering on and powering off the solenoid valve.

The structural design of the linkage gear 9 connecting the push shaft 11 and the dead bolt 7 of the present utility model can also realize the movement of the vertical direction of the push shaft 11 and the horizontal direction of the dead bolt 7 through other methods such as a single connecting rod or a multi-connecting rod. Movements are interchangeable.

In summary, the utility model solves the problems existing in the anti-theft lock of the traditional technology through the above-mentioned structural design, has the characteristics of simple structure, convenient operation, and good anti-theft performance, and can be widely used in bicycles, electric vehicles or automobiles. On the direction axis, it has a wide range of market value and huge market potential.
