[0024] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the drawings in the embodiments of the present utility model;

[0025] Please refer toFigures 1-3 , in the present utility model, a clamping device for an elevator landing door panel includes a workbench frame 1. Guide rails 2 are fixedly installed on both the front and back of the workbench frame 1. Slide blocks 3 are slidably connected to both guide rails 2. An activity cavity 4 is formed in the workbench frame 1. A connecting rod 5 is slidably installed inside the activity cavity 4. Both ends of the connecting rod 5 are fixedly connected to the adjacent slide blocks 3 respectively. A pneumatic telescopic rod 6 is fixedly installed on the slide block 3. A clamping block 7 is fixedly installed at the top of the pneumatic telescopic rod 6, and one side of the clamping block 7 extends above the workbench frame 1. A vacuum pump 8 is fixedly installed on the workbench frame 1. The suction port of the vacuum pump 8 is connected to the inside of the connecting rod 5 through a pipeline. A connecting pipe 9 is fixedly installed between both ends of the connecting rod 5 and the pneumatic telescopic rod 6, and they are connected through the connecting pipe 9.

[0026] In the present utility model, the elevator landing door panel is placed on the tabletop of the workbench frame 1. Then, according to the position distribution that needs to be clamped and fixed, the slide block 3 on the front of the guide rail 2 is slid. Since the slide block 3 on the front is connected to the slide block 3 on the back through the connecting rod 5, the slide block 3 on the back slides synchronously. Then the vacuum pump 8 works. By reducing the negative pressure inside the pipeline, the connecting rod 5 and the pneumatic telescopic rod 6, the pneumatic telescopic rod 6 is driven to contract, causing the clamping block 7 to descend and cooperate with the workbench frame 1 to clamp the components of the elevator landing door panel. The position of the clamping block 7 can be adjusted according to the processing position requirements and the clamping position of the workpiece of the elevator landing door panel, and the clamping blocks 7 on the front and back are synchronously clamped to ensure the clamping stability of the elevator landing door panel, facilitating the processing operation.

[0027] Please refer to Figure 1 , wherein: an arc-shaped storage rack 10 is integrally formed on the left side of the workbench frame 1. The guide rail 2 and the activity cavity 4 both extend to the arc-shaped storage rack 10.

[0028] In the present utility model, since the guide rail 2 and the activity cavity 4 both extend to the arc-shaped storage rack 10, the slide block 3 and the connecting rod 5 can slide within the range of the guide rail 2 and the activity cavity 4 onto the arc-shaped storage rack 10 to store all or part of the unused clamping blocks 7, reducing the obstruction and facilitating the processing of the elevator landing door panel.

[0029] Please refer to Figure 1 , wherein: the number of slide blocks 3 installed on both guide rails 2 is more than two, and the numbers correspond to each other.

[0030] In the present utility model, multiple slide blocks 3 can synchronously clamp and fix different parts of the elevator landing door panel, and the redundant clamping blocks 7 can be stored on the arc-shaped storage rack 10 to meet the usage requirements of users.

[0031] Please refer to Figure 2 And Figure 3, wherein: two supporting blocks 51 are integrally formed on the connecting rod 5, and the supporting blocks 51 are located inside the movable cavity 4 and are in smooth contact with the inner wall of the movable cavity 4.

[0032] In the present utility model, the supporting blocks 51 facilitate the sliding of the connecting rod 5 inside the movable cavity 4, and at the same time support the movable cavity 4, reducing or avoiding the deformation problem of the workbench frame 1 caused by the opening of the movable cavity 4, and improving the structural strength of the workbench frame 1.

[0033] Please refer to Figure 2 and Figure 3 , wherein: a threaded rod 31 is inserted through the slider 3 and is threadedly connected thereto, and one end of the threaded rod 31 located inside the slider 3 contacts the guide rail 2.

[0034] In the present utility model, by rotating the threaded rod 31, the friction force between it and the guide rail 2 can be utilized to fix the position of the slider 3, preventing the continuous sliding of the slider 3 and maintaining the stability of the clamping of the elevator landing door panel.

[0035] Please refer to Figure 1 and Figure 2 , wherein: a solenoid valve 11 is fixedly installed on the pipeline between the vacuum pump 8 and the connecting rod 5, a control panel 12 is installed on the workbench frame 1, and both the solenoid valve 11 and the vacuum pump 8 are electrically connected to the control panel 12.

[0036] In the present utility model, by operating the control panel 12 to control the opening and closing of the solenoid valve 11, the opening and closing states of each pipeline communicating with the connecting rod 5 can be controlled.

[0037] The above is only the preferred specific embodiment of the present utility model; however, the protection scope of the present utility model is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present utility model, according to the technical solution and its improvement concept of the present utility model, makes equivalent substitutions or changes, and should be covered by the protection scope of the present utility model.
