In this embodiment, the left lock bracket 102 is provided with the elongated hole 1021, and the left lock rail 101 is fixed on the elongated hole 1021 through the screw, so that the position of the left lock rail 101 fixed on the left lock bracket 102 can be adjusted by changing the fixing position of the screw on the elongated hole 1021, and the left lock rail 101 touches the locking system 5 more accurately.
The right walking support 2 and the left walking support 1 are identical in structure, and the position of the right walking bracket and the left walking support 1 on the left side are in a mirror image relationship. Similarly, the right transmission mechanism 7 comprises a right fixing part and a right belt connecting arm, the right fixing part is fixed on the other side of the belt, one end of the right belt connecting arm is rotatably connected to the right fixing part, the other end of the right belt connecting arm is rotatably connected to the right walking bracket, and therefore the belt and the right fixing part can drive the right walking bracket to move left and right through the right belt connecting arm.
The right opening and closing mechanism has the same structure as the left opening and closing mechanism 10, but the moving direction is just opposite, and the detailed description is omitted.
The motor 8 drives the belt 4 to reciprocate, the driving force and the locking force of the left walking bracket 1 and the right walking bracket 2 are provided through the left transmission mechanism 6 and the right transmission mechanism 7, and the action of the motor is started and stopped through the left micro switch 55 and the right micro switch 56.
Other transmission mechanisms, such as screw transmission, can also be used to provide the driving force and the locking force of the left walking bracket 1 and the right walking bracket 2 through the left transmission mechanism 6 and the right transmission mechanism 7.
When the door is closed, the belt 4 moves under the action of the motor 8, and the belt 4 drives the left walking bracket 1 and the right walking bracket 2 to move through the connecting arm 61, and at the moment, the running state of the left and right walking brackets is as shown in fig. 2. When moving in the door closing direction, the left belt connecting arm 61 first contacts the right side 1021 of the frame 102, and then drives the left traveling bracket to move, and the movement of the left belt connecting arm is similar to that of the left belt connecting arm 61. As the left and right traveling brackets move, the traveling bracket upper lock rail 101 collides against the left and right lock block supports 52 and 54, and then the left and right lock hooks 51 and 53 hook the touching portion 1011 of the lock rail 101, and at this time, the door system is locked. At the same time, when locked in place, the switch trigger wheels 551, 561 are released, as shown in fig. 2.
When the door system opens the door, the motor 8 acts first to drive the belt 4 to rotate circularly, and because the left and right belt connecting arms and the left and right bracket middle supports have a 10 ° angle gap, the belt 4 will pull the left belt connecting arm 61 to the left side 1022 of 102 for contact, the idle stroke rotation of the left connecting arm 61 will take up the left locking hook 51 through the protrusion 612, and similarly, the idle stroke of the right belt connecting arm 71 will take up the right locking hook 53. At this time, the lock-in-place switch is triggered, the lock rail 101 is separated along with the movement of the traveling bracket, the left lock block support 52 and the right lock block support 54 rotate under the action of gravity, and then the left lock hook 51 and the right lock hook 53 are supported to return to the position state shown in fig. 8, and the electric unlocking and door opening are completed.
The mechanism also comprises a manual unlocking mechanism which comprises a top block 571, a locking rod 572, pushing parts 573, 21274, a shape bracket 591, 21274, wherein the shape bracket 591 is fixed on the supporting frame 59 through screws, the locking rod 572 vertically penetrates through the 21274, the shape bracket 591 is provided with the top block 571 on the upper part of the locking rod 57, the top block 571 is supported by the upper edge of the shape bracket 591, two sides 5711 of the top block 571 are aligned with the bottom edge at the inner end of the left locking hook 51 and the bottom edge at the inner end of the right locking hook 53, and the pushing part 573 is arranged at the lower part of the locking rod 572.
If manual unlocking is needed, the pushing part 573 is directly pushed upwards by hand, the pushing part 573 drives the lock bar 572 upwards, so that the top block 571 pushes the inner end of the left lock hook 51 and the inner end of the right lock hook 53 upwards, the left lock block supporting piece 52 and the right lock block supporting piece 54 exit from the lock stopper limit under the action of self gravity and push the inner end of the left lock hook 51 and the inner end of the right lock hook 53 downwards, and manual unlocking and door opening are realized, as shown in fig. 5 and 7.
