Detailed Implementation
[0027] like Figures 1-7 As shown, the lock sleeve 5 is a square sleeve. A guide pin 12, a guide pin cover 3, and a stop arm 13 are mounted on the upper wall of the sleeve using pins. The guide pin cover is symmetrically held in place by tension springs 6 on both sides, maintaining its position of covering the guide pin. The upper end of the stop arm 13 is bent to slide on the pin sleeve 2, and the lower end is mounted on the stop arm seat. A torsion spring 11 is mounted on the pin of the stop arm, with one end pressing against the stop arm and the other end pressing against the lock sleeve, forming a pressing posture of the stop arm against the guide pin and the guide pin cover. The guide pin is a rectangular piece that remains in constant contact with the lock tongue 7.
[0028] The lock sleeve has a push-pull groove 501 on the side where the stop arm seat is located, so as to allow the push-pull pin seat 10 to move and be restrained. The lock sleeve has a ground pin key moving groove 502 on the side facing the ground, so as to allow the ground pin key 8 to move. The connection method between the ground pin key and the ground pin is the same as in the applicant's patent mentioned above. However, in this utility model, a spring is installed inside the ground pin hole, and a sealing plate is installed on top, which seals the ground pin hole when the door is opened and the ground pin is pulled out to prevent foreign objects from blocking it.
[0029] The bottom of the lock sleeve has a base cover 14, which is connected with screws and other connectors to allow for maintenance from this point.
[0030] The latch 7 is a movable cylinder that adapts to the lock sleeve; it can be hollow or solid. The top of the latch has a curved surface to facilitate sliding contact with the guide pin. The latch has a push rod pin mounting hole 701 and a ground pin mounting hole 702.
[0031] The left door leaf 1 and the pin sleeve 2 are consistent with the conventional door leaf. The push rod 9 is the existing electric push rod.
[0032] The rest is the same as the above patent.
[0033] Compared with the above patent, the utility model, the lever and the lock pin push-pull sleeve and other components between the push rod and the lock tongue are simplified, the friction of the system is reduced, and the power consumption is naturally reduced. Also effectively avoid the external interference factors such as wind vibration on the timing of the lock tongue into the pin sleeve, realize the normal and accurate automatic door leaf opening and closing.
[0034] The rest of the components and labels are as described above.
