[0030] The inner cavity of the adjusting plate 3 is provided with an installation groove 4, the bottom of the installation groove 4 is provided with a moving hole 5, the front side of the adjusting plate 3 is provided with a pull hole 6, and the inner cavity of the installation groove 4 is provided with a fixing component 7.

[0031] Control component 8 is disposed in the inner cavity of pull hole 6.

[0032] Specifically, when it is necessary to adjust the elevator foot guard, the fixing component 7 can fix the adjusting plate 3 at different positions, and the control component 8 can easily control the operation of the fixing component 7.

[0033] Furthermore, when it is necessary to adjust the elevator foot plate to adapt to different buildings, insert your palm into the pull hole 6 on the front side of the foot plate 1 to control the movement of the adjustment plate 3. The anti-detachment hole 9 and the anti-detachment plate 10 can prevent the adjustment plate 3 from detaching.

[0034] Example 2

[0035] The second embodiment of this utility model provides an adjustable elevator foot guard. The fixing component 7 includes two movable plates 71. Springs 72 are fixedly connected to the top and bottom of the opposite side of the two movable plates 71. Connecting rods 73 are fixedly connected to the opposite side of the two movable plates 71. The side of the connecting rod 73 away from the movable plate 71 passes through the mounting groove 4 and is fixedly connected to the insertion block 74. A control hole 11 is opened on the side of the movable plate 71 near the spring 72. A control rod 12 is movably connected to the inner cavity of the control hole 11. The left and right sides of the control rod 12 are fixedly connected to the inner wall of the mounting groove 4. The left and right sides of the adjusting plate 3 are provided with mating grooves 13. The left and right sides of the inner cavity of the adjusting groove 2 are provided with insertion holes 14 for use with the insertion block 74. There are multiple insertion holes 14. The insertion block 74 is inserted into the inner cavity of the insertion hole 14.

[0036] Specifically, by setting the fixing component 7, control hole 11, control rod 12, mating groove 13 and insertion hole 14, the connecting rod 73 moves to drive the insertion block 74 to be inserted into the insertion hole 14 at different positions, which can fix the adjustment plate 3 at different positions. The pressure of the spring 72 on the movable plate 71 prevents the movable plate 71 from moving randomly. The control rod 12 and control hole 11 can control the movement position of the movable plate 71.

[0037] Furthermore, when the adjusting plate 3 is moved to the appropriate position, the pressing plate 83 is released, the spring 72 will undergo elastic deformation, the movable plate 71 will return to its original position, and the movement of the movable plate 71 will drive the plug block 74 fixed on the connecting rod 73 to be inserted into the plug hole 14. At this time, the position of the adjusted plate 3 after movement can be fixed.

[0038] Example 3

[0039] The third embodiment of this utility model provides an adjustable elevator foot guard. The control component 8 includes a control block 81. The top of the control block 81 is fixedly connected to the movable plate 71. A pressing hole 82 is opened on the front side of the control block 81. A pressing plate 83 is movably connected to the inner cavity of the pressing hole 82. A stroke groove 15 is opened on the left and right sides of the inner cavity of the pull hole 6. A stroke block 16 is movably connected to the inner cavity of the stroke groove 15. The side of the stroke block 16 near the pressing plate 83 is fixedly connected to the pressing plate 83.

[0040] Specifically, by setting up control component 8, stroke groove 15 and stroke block 16, when it is necessary to control the movement of two movable plates 71 at the same time, pull down the extrusion plate 83. The movement of the extrusion plate 83 will squeeze the inner wall in the extrusion hole 82. The inclined surfaces squeeze each other, which will drive the two movable plates 71 to move. The stroke block 16 and stroke groove 15 can control the movement position of the extrusion plate 83, so that the extrusion plate 83 will not detach.

[0041] Furthermore, the extrusion plate 83 is then pulled down. The movement of the extrusion plate 83 will extrude the inner wall within the extrusion hole 82. At this time, the extrusion force generated by the inclined plane will cause the two control blocks 81 to move closer to each other. The movement of the control blocks 81 will cause the movable plate 71 to move.

[0042] Working principle:

[0043] When the elevator foot guard needs to be adjusted to suit different buildings, insert your palm into the pull hole 6 on the front side of the guard plate 1, and then pull down the pressing plate 83. The pressing plate 83 moves and presses the inner wall in the pressing hole 82. At this time, the pressing force generated by the inclined plane will drive the two control blocks 81 to move closer to each other. The movement of the control block 81 will drive the movable plate 71 to move. The movement of the movable plate 71 will compress the spring 72 and drive the connecting rod 73 to move. The movement of the connecting rod 73 will cause the plug block 74 to disengage from the plug hole 14 and move into the mating groove 13. Then pull the adjusting plate 3 to move in the adjusting groove 2. When the adjusting plate 3 moves to the appropriate position, release the pressing plate 83. The spring 72 will undergo elastic deformation and the movable plate 71 will return to its original position. The movement of the movable plate 71 will drive the plug block 74 fixed on the connecting rod 73 to insert into the plug hole 14. At this time, the position of the adjusted plate 3 after movement can be fixed.

[0044] In summary, the length adjustment effect is achieved through the cooperation of the guard plate 1, the adjustment groove 2, the adjustment plate 3, the mounting groove 4, the moving hole 5, the pull hole 6, the fixing component 7, and the control component 8.
