When the electronic lock cannot realize electronic unlocking and a mechanical key is used for emergency, in the case of normal mechanical opening of the mechanical key, the pin moves in a straight line along the radial direction of the box body toward the center of the circle, that is, the end of the pin is directly in contact with the center of the circle. The limit hole cooperates so that the box body and the rotating core rotate together, and the handle of the electronic lock body rotates accordingly. At the same time, during the rotation of the handle, multiple pins are movable, that is, when the box body and the rotating core are synchronized During the rotation process, a plurality of pins are sequentially matched with the corresponding limit holes, and the pins after the mating are returned to the initial position under the elastic return force of the spring A, and reciprocate in this way until the lock is fully opened . However, when electronic unlocking is used, and the lock cylinder is in an empty rotation state when the door is closed, the handle cannot open the door lock. When the door needs to be opened, the electronic signal is transmitted to the driver's command of the electronic lock body. At this time, multiple pins and limit holes , to realize the overall linkage of the belt box body and the handle as a transmission, and realize the door opening. During the rotation of the handle, multiple pins take turns to realize uninterrupted work until the door opening action is completed. Therefore, the utility model can ensure that electronic unlocking and mechanical unlocking are realized at the same time, and when dealing with mechanical emergencies, the operation is simple, convenient and practical. Among them, in the process of mechanical unlocking or electronic unlocking, multiple pins move linearly along the radial direction of the box body in sequence. When the pins are in contact with the limit hole, spring A is compressed, while spring B is stretched, that is For the pin body, the spring B weakens its motion inertia along the radial direction of the box to the center of its circle to the greatest extent, so that the end of the pin reduces its impact on the rotating core after entering the limiting hole , and when the pin is disengaged from the limit hole, the spring B recovers and deforms, while the spring A is stretched, that is to avoid the end of the rectangular groove on the pin directly colliding with the lower end of the flange violently, and at the same time quickly move the pin The motion state is stabilized to keep it in its initial static state, so as to facilitate the opening and closing of the door lock.

Then the pin can quickly enter the adjustment section. With the movement of the rotating core, the end surface of the pin slides over the smooth transition surface and then enters the straight section smoothly, that is, the rapid alignment of the pin and the limit hole is realized, ensuring that the pin The column quickly drives the rotating core to move to complete the unlocking.

When working, the driver directly cooperates with the clutch. When the door is closed, the clutch is in an idling rotation state, and the handle cannot open the door lock. When the door needs to be opened, the electronic signal is transmitted to the cylinder connected to the end of the upper ejector rod, and the output end of the cylinder is pushed out. The connecting head in the active cavity drives the connecting rod to move upward, and at the same time the connecting plate and the support seat also move upward together with the connecting rod, thereby realizing the upward displacement of the shrapnel in the vertical direction until the shrapnel contacts the pin of the clutch, and the It pushes into the square hole, so that the clutch and the handle become a whole linkage of transmission to realize unlocking; and when the electronic circuit or cylinder is damaged, the motor in the passive cavity starts to run through the mechanical emergency key, and the motor rotates, making The small gear and the large gear start to rotate and cooperate, and the screw starts to rotate. At this time, the support seat in the passive cavity is engaged with the second support block, and the support seat is also restricted by the connecting plate and the connecting rod and cannot be combined with the screw. Rotate, that is, the relative movement between the second support block and the screw rod, the second support block, the support seat, the shrapnel, the connecting plate and the connecting rod all start to move upward, and the shrapnel pushes the pin to move up, so that the linkage between the clutch and the square hole , to achieve unlocking. The shrapnel adopts a circular arc shape, which can keep the two adjacent pins on the clutch in contact with the square hole in continuity, and through electronic and mechanical unlocking methods, while bringing convenient and quick unlocking methods, the lock is improved. The practical performance of the body, and the handle is always in an idling state when the door is closed, so that criminals cannot unlock the lock outdoors or indoors through the handle, which enhances the safety performance of the lock body.

The inner diameter of the limiting hole is larger than the outer diameter of the pin. Before the pins are matched with the limiting holes, the box body and the rotating core are two separate entities. After the pins are matched with the limiting holes, multiple pins drive the corresponding limiting holes and the rotating core to rotate together to realize unlocking. Purpose, when the pin drives the rotating core to move, the aperture of the limiting hole is larger than the outer diameter of the pin, so that the pin can move freely in advance for a certain distance in the limiting hole until the outer wall of the pin and the inner wall of the limiting hole Contact, using the inertia of the pin to quickly drive the rotor to move, avoiding the pin directly driving the rotor in the initial state and increasing the workload of the driver, that is, reducing the difficulty of electronic or mechanical unlocking.

The number of the pins is 6. As a preference, the number of pins is set to 6, and they are evenly distributed on the circumferential wall of the box body. When the rotating core rotates, the contact and force of the pins with the limit holes are more uniform, that is, the door The stability of the lock when it is opened or closed, while reducing the wear between the rotor and the box.

Both spring A and spring B are torsion springs. As a preference, a torsion spring is selected to ensure the stability of the elastic force of the spring C and the elastic recovery force during the continuous expansion and contraction of the pin in the box body, so as to ensure the smooth progress of both mechanical unlocking and electronic unlocking, and the torsion spring It can withstand forces in different directions, and prolong the service life of spring C and other parts under repeated use.

A spring C is also included, one end of the spring C is connected to the upper wall of the active cavity, and the other end of the spring C is connected to the upper end surface of the connector.
