[0028] Specifically, a fixing ring 12 is fixedly installed inside the side groove 5, and a movable rod 13 is movably connected to the inner side of the fixing ring 12. Lug plates are fixedly installed on both sides of the movable plate 7, and the lug plates are located inside the side groove 5, and the movable rod 13 is located on the back of the lug plates.

[0029] The fixing ring 12 and the movable rod 13 cooperate with each other to squeeze the convex plate and displace the convex plate, and then the convex plate drives the movable plate 7 to displace deep into the groove 4, so that the stop block 8 and the card block 10 are disengaged, making it convenient to adjust the key plate 9 upward.

[0030] Specifically, strip plates 14 are fixedly installed on the back side of the vertical plate 3 and on both sides of the key plate 9, and limiting grooves 15 are provided on the relatively close sides of the strip plates 14. Limiting blocks 16 are fixedly installed on both sides of the key plate 9. The limiting blocks 16 are located inside the limiting grooves 15. A return spring 17 is fixedly installed inside the limiting grooves 15, and the top of the return spring 17 is fixedly connected to the limiting block 16.

[0031] The limiting groove 15 and the limiting block 16 cooperate with each other to limit the key plate 9, thereby improving the stability of the key plate 9 when adjusting the height, and thereby preventing the key plate 9 from deflecting. Under the action of the reset spring 17, the key plate 9 is automatically bounced upward, so that the key plate 9 is reset to the highest point. When the key plate 9 needs to be moved up to the highest point, the movable plate 7 is squeezed under the action of the fixing ring 12 and the movable rod 13, so that the blocking block 10 and the stop block 8 are disengaged, and then the key plate 9 is bounced upward under the elastic force of the reset spring 17, so that the key plate 9 is moved up and reset to the highest point.

The other side of the compression spring 19 is fixedly connected to the friction block 20. Two friction plates are arranged on the side of the key panel 9 close to the friction block 20, and the friction blocks 20 are respectively against the friction plates.

[0035] The compression spring 19 is used to squeeze the friction block 20 so that the friction block 20 and the friction plate always maintain contact and abutment with each other, thereby playing a damping and decelerating role on the key plate 9 when the key plate 9 moves up, avoiding the key plate 9 from moving up at a too high speed and preventing the key plate 9 from shaking violently when it moves up into place.

[0036] Specifically, a mounting plate is fixedly mounted on the back of the vertical plate 3 and above the key plate 9 , and a buffer rubber block 21 is fixedly mounted on the bottom of the mounting plate, and the bottom of the buffer rubber block 21 abuts against the top of the key plate 9 .

[0037] The friction block 20 is used to limit and buffer the key panel 9 to prevent the key panel 9 from moving up too much, resulting in poor positioning of the key panel 9, and to prevent the limit block 16 from colliding with the inner side of the limit slot 15 when the key panel 9 moves up.

[0038] During use, when the elevator body 1 fails and the passenger needs to ask for help, but the passenger is short, the passenger can first grab the handle and pull it downward with force, thereby driving the keypad 9 to move downward. During the downward movement of the keypad 9, the keypad 9 drives the card block 10 to squeeze the passing stop block 8. When the keypad 9 is adjusted to a suitable height, the passenger can easily press the emergency button 11, thereby facilitating the passenger to ask for help. When the keypad 9 stops moving, the card block 10 is connected to the bottom of the stop block 8, and the keypad 9 cannot move upward at this time. When the key plate 9 needs to be reset upward, the movable rod 13 is pressed at the same time, so that the movable rod 13 squeezes the convex plate, and then the convex plate drives the movable plate 7 to move away from the key plate 9, and then the movable plate 7 drives the stop block 8 to disengage from the card block 10, so that the key plate 9 can move upward, and at the same time, under the action of the reset spring 17, the limit block 16 is bounced upward, thereby driving the key plate 9 to move upward, and under the damping action of the friction block 20 and the friction plate, the key plate 9 slowly moves upward until the top of the key plate 9 contacts the friction block 20.
