Lock bodies are one of the components of locks, and there are many kinds of lock bodies, and common lock bodies include one-way lock bodies, three-way lock bodies, and four-way lock bodies. The lock body is responsible for the effect of opening or locking the door and window, plays important effect in the theftproof. The lock body is generally used on the anti-theft door, and the lock body is controlled to operate through the lock cylinder to take charge of the basic anti-theft work of the anti-theft door.
The existing lock body is high in safety level and generally provided with a top hook, a ground hook, an oblique bolt and a main square bolt, wherein the oblique bolt and the main square bolt extend towards one side of a door frame and are clamped into the door frame to form a locking point, and the top hook and the ground hook respectively extend upwards and downwards in a one-to-one correspondence mode to form an upper locking point and a lower locking point. The main square bolt, the top hook and the ground hook are extended out to carry out back locking, and the inclined bolt is extended out to not carry out back locking.
The lock body has the function of automatic back locking, namely when the lock is unlocked by a key, the top hook, the ground hook, the latch bolt and the main square bolt can retract, the latch bolt can automatically extend after the lock is unlocked, and the top hook, the ground hook and the main square bolt can not extend, so that the back locking is not carried out. But when the latch bolt is pressed to retract, the latch bolt can trigger the latch lock, namely, the top hook, the ground hook, the latch bolt and the main square bolt are all extended out, so that the automatic latch lock is realized. The existing lock body has the disadvantages of complex structure, low performance and high production and manufacturing cost in order to realize the automatic back locking function.
When unlocking, in order to drive the top hook, the ground hook and the main square bolt to retract, a large torque is often required, a large-volume motor needs a large current as a power supply, the load of the motor is large, and the service life of the motor is seriously influenced. In addition, this again results in a larger lock body. In order to meet the torque requirement during unlocking, the conventional electronic lock body has larger volume, and is not beneficial to popularization of the electronic lock body in small lock bodies.
Because the top hook, the ground hook and the main square bolt of the lock body adopt a linkage mode, the lock body synchronously extends and retracts. If one of the lock bodies can not extend out due to external factors (such as deformation of a door frame or blockage of foreign matters), the other two lock bodies can not extend out, so that counter locking can not be realized, and great potential safety hazards exist.

Example two
As shown in fig. 4 to 6, the present embodiment provides a lock cylinder connecting structure, which includes a lock cylinder connecting rotating shaft 23, a main square bolt shifting fork 24 and a top and bottom hook shifting tooth 25, in order to realize the coaxiality, the lock cylinder connecting rotating shaft 23 is provided with a mounting shaft 26, and the main square bolt 19 and the top and bottom hook shifting tooth 25 are sequentially sleeved on the mounting shaft 26 and are rotatably connected by the mounting shaft 26.

When rotating counterclockwise, the third reset piece 17 will shorten the release potential energy to provide a large enough torque for the back locking.
The principle of the device is as follows:
during the back locking, because the lock core connecting rotating shaft 23 has an idle rotation angle, the boss 27 of the lock core connecting rotating shaft 23 firstly contacts with the boss 27 on one side of the main square bolt shifting fork 24 to drive the main square bolt shifting fork 24 to rotate, then the boss 27 on the other side of the main square bolt shifting fork 24 contacts with the boss 27 of the top and bottom hook shifting teeth 25, finally the main square bolt shifting fork 24 shifts the main square bolt 19 to extend, and simultaneously the top and bottom hook shifting teeth 25 drive the bottom hook 21 and the top hook 20 to extend. Therefore, if the top hook 20 is blocked, the extension of the main square tongue 19 is not affected, and if the main square tongue 19 is blocked, the extension of the ground hook 21 and the top hook 20 is not affected, and the two parts are independent and do not affect each other, so that the probability of the locking failure is reduced, and the safety level is improved.
