The driving end of the driving rod 4 is hinged, and a long hole slide groove 13 is provided at the front part of the locking rod rear section 10. A spring sleeve rod 14 extending forward is provided on the back side of the locking rod rear section 10 at the rear side of the long hole slide groove 13. A laterally protruding locking rod slider 15 and a push plate 16 are provided at the rear part of the locking rod front section 9. The locking rod slider 15 of the locking rod front section 9 is slidably fitted in the long hole slide groove 13 of the locking rod rear section 10. The compression spring 11 is sleeved on the spring sleeve rod 14 and the front end of the compression spring 11 presses against the locking rod slider 15. The motor driver 7 is fixedly mounted on the lock housing 1, and the sliding block 8 is slidably fitted on the lock housing 1. The driving screw 17 on the motor driver 7 is threadedly fitted with the screw hole of the sliding block 8, and the driving end 18 of the sliding block 8 is pushed and fitted with the push plate 16 of the locking rod front section 9.

[0028] In addition, if Figure 1 As shown, when the sliding block 8 is at its front stop position, the front section 9 of the locking rod is at the position of the locking head closed state; Figure 6 As shown, when the sliding block 8 is at its rear stop position, the front section 9 of the locking rod is at the position where the lock head is opened.

[0029] like Figure 1 and Figure 7 As shown, when the sliding block is at its front stop position, the key rotates the lock cylinder 2 to drive the driving rod to move forward and backward, and the lock rod rear section 10 and the compression spring 11 cooperate to drive the lock rod front section 9 to the open state or closed state of the lock head.

[0030] The motor driver 7 is composed of a stepper motor 19, a transmission 20, a driving screw 17 and a bearing seat 21, wherein the transmission 20 is located in front of the stepper motor 19, the output shaft of the stepper motor 19 is connected to the input shaft of the transmission 20, the output shaft of the transmission 20 is connected to one end of the driving screw 17, the other end of the driving screw 17 is installed on the bearing seat 21, the bearing seat 21 is fixedly installed on the lock housing 1, and the sliding block 8 is threadedly engaged on the driving screw 17 between the output shaft of the transmission 20 and the bearing seat 21.

[0031] The front section 9 of the lock rod and the rear section 10 of the lock rod are respectively slidably matched with the lock housing 1, and a long hole nail groove 22 is respectively opened on the front section 9 of the lock rod and the rear section 10 of the lock rod, and a sliding screw 24 with a smooth rod section 23 passes through the long hole nail groove 22 and is locked on the lock housing 1, and the smooth rod section 23 of the sliding screw 24 is slidably matched with the long hole nail groove 22.

[0032] The distance setting of the sliding block 8 from the front stop position to the rear stop position is determined by setting the continuous working time of the stepping motor 19, or by setting a displacement sensor between the sliding block 8 and the lock housing 1 or between the front section 9 of the lock rod and the lock housing 1.

[0033] On one of the lock heads, the driving rod 4, the locking rod 5, the motor driver 7 and the sliding block 8 cooperate with each other in a working mechanism group, which is a group arranged on the left side of the lock core 2, that is, Figure 1 or two groups respectively disposed on the left and right sides of the lock core 2, that is, Figure 5 shown.

[0034] The other end of the locking rod 5 directly serves as a locking bolt, and the outer end section 25 of the locking rod front section 9 extends out of the side of the lock housing 1 when the lock head is in the closed state, that is, Figure 1 The outer end section 25 of the front section of the lock rod 9 is retracted into the side of the lock housing 1 when the lock is in the open state, that is, Figure 6 or Figure 7 shown.

[0035] The other end of the lock rod is driven to cooperate with the lock buckle 26, and a driving protrusion 27 for driving the lock buckle and an unlocking paddle hanging nail 28 cooperating with the lock buckle are provided on the front section 9 of the lock rod. The lock buckle 26 is installed on the lock housing 1.

[0036] The lock housing 1 is also provided with a control circuit 29 and a battery 30 . The control circuit 29 is connected to the stepping motor 19 and the remote controller for corresponding control, and the battery 30 is connected to the control circuit 29 and the stepping motor 19 for power supply.

[0037] When using, Figure 1 The lock head is in a closed state and can be opened electrically. Figure 6 As shown, when the control circuit 29 receives the control signal, it controls the stepper motor 19 to start working, drives the sliding block 8 to move inward through the transmission 20 and the driving screw 17, and the driving end 18 of the sliding block 8 pushes the push plate 19 of the front section 9 of the lock rod inward, and the lock rod slider 15 of the front section 9 of the lock rod slides inward in the long hole slide groove 13 of the rear end 10 of the lock rod and compresses the compression spring 11. When the sliding block 8 reaches its rear stop position, the stepper motor 19 stops working. At this time, the outer end section 25 of the front section 9 of the lock rod retracts into the lock housing 1 and exits the lock hole on the door frame; if the lock is opened electrically, the lock must be closed electrically; when the lock is closed electrically, Figure 6 The lock shown is in the open state. When the control circuit 29 receives the control signal, it controls the stepper motor 19 to start working, and drives the sliding block 8 to move outward through the transmission 20 and the driving screw 17. The lock rod slider 15 of the lock rod front section 9 slides outward in the long hole slide groove 13 of the lock rod rear section 10 under the push of the compression spring 11. The push plate 19 of the lock rod front section 9 moves outward along the driving end 18 of the sliding block 8. When the sliding block 8 reaches its front stop position, the stepper motor 19 stops working. At this time, the outer end section 25 of the lock rod front section 9 extends out of the lock housing 1 and enters the lock hole on the door frame, which is Figure 1 The status shown. Figure 1 The lock head is in a closed state and can be opened mechanically. Figure 7 As shown, a key is inserted into the lock cylinder 2, and the driving rod 4 is rotated to move inward. Through the inward movement of the lock rod rear section 10, the long hole slide groove 13 of the lock rod rear section 10 pulls the lock rod slider 15 of the lock rod front section 9, so that the outer end section 25 of the lock rod front section 9 is retracted into the lock shell 1 and thus exits the lock hole on the door frame; if the lock is opened mechanically, the lock must be closed mechanically; when the lock is closed mechanically, Figure 7In the unlocked state of the lock shown in the figure, a key is inserted into the lock cylinder 2 to rotate and drive the driving rod 4 to move outward. Through the outward movement of the lock rod rear section 10, the compression spring 11 on the lock rod rear section 10 pushes the lock rod slider 15 of the lock rod front section 9 to move forward in the long hole slide groove 13, so that the outer end section 25 of the lock rod front section 9 extends out of the lock housing 1 and enters the lock hole on the door frame, that is, Figure 1 Status shown.
