When the edge of the pushing area 201b on the left side of the pushing member 201 contacts with the first pushing post 103, the locking post 102 reaches the leftmost position at this time, the rotating disc 302 continues to rotate clockwise, the second pushing post 104 contacts with the rotating shaft area 201a, and the rotating shaft area 201a provides pushing force for the second pushing post 104 to cooperate with the first pushing post 103 to enter the lower half of the pushing area 201b on the left side of the pushing member 201, during this movement, the positions of the first pushing post 103 and the second pushing post 104 are cooperatively maintained by the rotating shaft area 201a and the lower half of the pushing area 201b, that is, during this rotation, the horizontal position of the locking post 102 does not change, and through a sufficient operation margin, the operation error of the staff is reduced.
By continuing to rotate the rotating disc 302, the pushing member 201 is turned upside down, the pushing area 201b on the left side of the original pushing member 201 is abutted against the second pushing post 104, and the pushing area 201b on the left side of the original pushing member 201 pushes the second pushing post 104 to displace rightward, and the moving process is mirror image to the unlocking process of the locking device, so that the locking device is locked.
During the rotation of the rotating disc 302, the racks extending from the two sides of the deflection member 307 are abutted against the extending ring 302a, and at this time, the first indicator plate 306a is opposite to the rotating disc 302, and whether the device is locked or not is known through the first indicator plate 306 a.
When the rotating disc 302 continues to rotate clockwise and the pushing piece 201 is turned upside down, the elastic plate 305 arranged on the side, close to the supporting table 303, of the extension ring 302a is contacted with the first deflection rod 307a of the deflection piece 307, at the moment, the deflection piece 307 rotates around the first deflection rod 307a under the action force of the first deflection rod 307a and the elastic plate 305, at the moment, racks on two sides of the deflection piece 307 enter the first groove 302a-1 formed on the extension ring 302a, the first deflection rod 307a on the deflection piece 307 continuously abuts against the elastic plate 305, the deflection piece 307 continuously rotates, the first groove 302a-1 drives the deflection piece 307 to complete the whole rotating process, the deflection piece 307 completes one-time deflection process, in this process, the locking device completes one-time locking/unlocking state switching, the deflection of the deflection piece 307 drives the connecting rotating rod 306 to rotate, and the rotation of the connecting rotating rod 306 completes switching of the first prompting plate 306a and the second prompting plate 306b so as to prompt the current state of the locking device.
The initial operation state of the locking device may be to rotate the rotating disc 302 counterclockwise, and the second groove 302a-2 is used to provide a guiding position for the deflecting member 307 when the rotating disc 302 is rotated counterclockwise, wherein the first deflecting rod 307a and the second deflecting rod 307b on the deflecting member 307 are arranged in an oblique symmetry along the central position of the deflecting member 307, and when the deflecting action of the deflecting member 307 is finished, the positions of the two deflecting rods are interchanged, and at this time, the functions born by the two deflecting rods are interchanged. (deflection support rod, standby deflection support rod)
