Referring to Figure 15, Figure 16, the upper latch hook in the utility model is identical with lower latch hook 3 symmetrical configuration, respectively comprises lock hook seat 31 and is arranged on the first locking hook 32, the second locking hook 33, the second spring 34, the 3rd spring 35 and the electromagnetic valve 36 on lock hook seat.Wherein, electromagnetic valve 36 is connected with the anterior transmission of the first locking hook 32, the second spring 34 is connected with the rear portion of the first locking hook 32, the 3rd spring 35 is connected with the rear portion of the second locking hook 33, the first locking hook 32 and the second locking hook 33 can form snap close, and the second locking hook 33 can form snap close with corresponding lock 4.One end of upper wire rope 5 or lower wire rope 6 and the rear portion of the first locking hook 32 are fixedly linked.
Referring to Figure 17, the upper lock in the utility model is identical with lower lock 4 structures, comprises that the installing plate 41 for being connected with doorframe buckles 42 with the U-shaped that is connected to the installing plate lateral surface.
Referring to Figure 18, coordinate referring to 1, the other end of the push rod 2 in Fig. 2, the utility model rotatably is connected with another frame of door body by connecting handle 21.
Push rod door lock of the present utility model is applied to the state of track traffic termination door as shown in Figure 19, Figure 20, Figure 21.Shown in figure, 7 is doorframe, and 8 is the door body, and 9 is upper hinge, and 10 is lower hinge.
The opening ways of door is revolving door, by upper and lower hinge rotation, realizes easily opening or closing of door.
The switch Principle of Process of door is:
Close the door:
Door one is pushed away gently, or by door closer, door rotates to the position of closing the door, then by latch hook just move can be conveniently with securely by door lock;
Open the door:
1. from the , Yong Keying spoon that opens the door outdoors by turn key ring 114, the transmission mechanism that key ring 114 drives in lock by the second shift fork 113, transmission mechanism drives upper and lower latch hook 3 actions by upper and lower wire rope 5,6 again, light twisting just can be opened lock.
2. from the door the inside, open the door, as long as push rod 2 one is pushed away gently, push rod drives the transmission mechanism in lock, and transmission mechanism drives upper and lower latch hook 3 actions by upper and lower wire rope again, just door can be opened.
The process of unblanking of upper and lower latch hook is: the first locking hook 32, under the effect of external force or electromagnetic valve 36, turns clockwise, and the second locking hook 33 is under the effect of the 3rd spring 35, and inverse clock rotates, thereby throws off with lock, has also just opened latch hook.
The sealed process of upper and lower latch hook: the second locking hook 33, in motion process, is collided with lock 4, thereby dextrorotation goes to the first locking hook 32 cutting ferrules, thereby lock is pinned, and securely latch hook has been pinned.
The electronic process of unblanking is, during energising, on electromagnetic valve 36 pull bars, moves, thereby drives the first locking hook 32 around the rotation of latch hook bearing pin, makes and the second locking hook 33 breaks away from, and latch hook is opened; During outage, valve pull rod resets under the effect of spring, the first locking hook 32 and the second locking hook 33 is pinned, thereby door lock is lived.
