[0011] Compared with the prior art, the utility model has the following beneficial effects:

[0012] 1. The positioning mechanism for the installation of the subway screen door can realize accurate positioning and stable clamping of the screen door in the left and right directions and the front and back directions through the motor drive system and related mechanical structures. This positioning method ensures that the screen door will not deviate or move during the installation process, improves the accuracy and stability of the installation, and at the same time improves the applicability and operability of the device.

[0013] 2.

[0018] The following will be combined with the drawings in the embodiments of the present application to clearly and completely describe the technical solutions in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of this application.

[0019] See also Figure 1-3A positioning mechanism for installing a subway screen door comprises a device platform 1, a device platform 1, a slide seat 7 is slidably connected to the top of the device platform 1 through a driving mechanism, and there are two groups of slide seats 7, the tops of the two groups of slide seats 7 are fixedly connected to a fixing frame 8, the inner side of the fixing frame 8 is fixedly connected to a supporting plate 9, and a clamping mechanism for stably clamping subway screen doors of different thicknesses is arranged on the fixing frame 8.

[0020] Through the above technical scheme, in the process of auxiliary installation and positioning of the subway screen door, the positions of the two groups of slides 7 can be moved by the driving mechanism to make them close to each other, until the two groups of fixing frames 8 cooperate with the support plates 9 to initially stabilize the subway screen door in the left and right directions, and cooperate with the locking mechanism to stably clamp it in the front and rear directions.

[0021] Specifically, the driving mechanism includes a motor 2 fixedly mounted on the device platform 1 , an output end of the motor 2 is fixedly connected to a driving plate 3 , and both ends of the driving plate 3 are fixedly connected to a first shaft 4 .

[0022] Through the above technical solution, after the motor 2 is turned on, it can drive the driving plate 3 to rotate, and the two groups of first shafts 4 at the ends of the driving plate 3 will rotate synchronously therewith.

[0023] Specifically, the outer surfaces of the two groups of first shafts 4 are rotatably connected with arc plates 5 , one end of the arc plate 5 away from the first shaft 4 is rotatably connected with the second shaft 6 , and the outer surface of the second shaft 6 is rotatably connected to the bottom of the slide seat 7 .

[0024] Through the above technical solution, the driving plate 3 will pull the arc plate 5 through the first shaft 4 during the rotation process, causing it to deflect.

[0025] Specifically, the positioning mechanism includes a fixing platform 10 fixedly connected to the fixing frame 8 , and a fixing seat 11 is arranged on the top of the fixing platform 10 .

[0026] Through the above technical solution, the arc plate 5 will rotate along the second axis 6 during the deflection process, and pull the slide 7 through the second axis 6, so that the two groups of slides 7 slide close to each other along the top of the device platform 1.

[0027] Specifically, a screw rod 12 is rotatably connected to the inner surface of the fixing platform 10 , and a knob 13 is disposed at one end of the screw rod 12 .

[0028] Through the above technical solution, rotating the knob 13 can drive the screw 12 to rotate, during which the fixed platform 10 always remains fixed, and the shifting platform 14 will gradually approach the fixed platform 10, that is, the shifting seat 15 will gradually approach the fixed seat 11 until the shielding door is firmly clamped in the front and rear directions.

[0029] Specifically, a shifting platform 14 is threadedly sleeved on the outer surface of the screw rod 12 , and a shifting seat 15 is disposed on the top of the shifting platform 14 .

[0030] Through the above technical solution, the bottom of the shifting platform 14 is relatively limited by the fixing frame 8, so that it will not rotate synchronously with the rotation of the screw rod 12, and can only move horizontally.

[0031] Working principle: In the process of auxiliary positioning and installation of subway screen doors, the screen doors need to be lifted onto the support plates 9 of the two sets of fixing frames 8 first, and the support plates 9 provide preliminary support for them. Then the screen doors need to be stably clamped and positioned, that is, the motor 2 is turned on to drive the driving plate 3 to rotate. During the rotation, the driving plate 3 drives the arc plate 5 through the first axis 4, so that the arc plate 5 deflects. During this period, the arc plate 5 pulls the slide 7 through the second axis 6, so that the two sets of slides 7 slide closer along the top of the device platform 1 until the fixing frame 8 firmly clamps the screen door in the left and right directions, and then the knob 13 can be rotated to drive the screw 12 to rotate. During this process, the shifting platform 14 will move axially along the screw rod 12, and the shifting card seat 15 will gradually approach the fixed card seat 11, until the shifting card seat 15 cooperates with the fixed card seat 11 and the friction surface opened on the inner side thereof, and firmly clamps the shielding door in the front-to-back direction. At this point, the shielding door is firmly stabilized on the support plate 9 in the fixed frame 8. Shielding doors of different sizes may differ in geometric shape or weight. By stably clamping them in the left-right and front-to-back directions at the same time, the changes of shielding doors of different sizes can be adapted. This design ensures that even if the shielding door is larger or smaller, its stability and safety on the fixed frame 8 and the support plate 9 can be guaranteed.

[0032] Although the embodiments of the present application have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present application, and that the scope of the present application is defined by the appended claims and their equivalents.
