[0015] Compared with the prior art, the beneficial effects of the present utility model are:
[0016] The utility model is provided with an adjusting block, an auxiliary block, an electric telescopic rod, a moving block, a clamping block, an auxiliary telescopic rod, a pressure sensor and a pressure spring, which can be adjusted conveniently according to the height of the screen door by relying on the sliding fit relationship between the adjusting block and the auxiliary block, and the moving block is pushed to move by the thrust generated by the electric telescopic rod, so that the two clamping blocks are in contact with the screen door. The first rubber pad can reduce the damage to the screen door during clamping.

DETAILED DESCRIPTION OF THE INVENTION
[0022] Please refer to Figures 1-4 Figures 1-4 , a positioning auxiliary frame for subway platform screen door installation, including a placement rack 1, and an auxiliary mechanism 2 is arranged inside the placement rack 1;
[0023] The auxiliary mechanism 2 includes two groups of adjusting blocks 201. Each group of adjusting blocks 201 is slidably connected to the inside of the placement rack 1. The upper surfaces of each group of adjusting blocks 201 are fixedly connected together with an auxiliary block 202. The left side surface of each adjusting block 201 is fixedly connected with a sliding block 3. Each sliding block 3 is slidably connected to the inside of the placement rack 1. The sliding block 3 can move simultaneously with the adjusting block 201, and the friction force generated by itself on the placement rack 1 during the movement is used to improve the stability of the adjusting block 201 during movement, increasing the stability of the device.
[0024] An electric telescopic rod 203 is fixedly connected to the inside of each auxiliary block 202. A plurality of equally spaced limiting holes 4 are formed inside each adjusting block 201. Four fixing bolts 5 are threadedly connected to the inside of the placement rack 1. One end of each fixing bolt 5 close to the adjusting block 201 extends into one of the limiting holes 4. Relying on the cooperation of the limiting hole 4 and the fixing bolt 5, the convenience of fixing the height positions of the adjusting block 201 and the placement rack 1 can be improved. Just insert the fixing bolt 5 into the placement rack 1 and the adjusting block 201.
[0025] The telescopic end of each electric telescopic rod 203 is fixedly connected with a moving block 204. A reinforcing ring 6 is fixedly connected to the outer surface of each electric telescopic rod 203. One ends of the two reinforcing rings 6 close to each other are fixedly connected to the side surface of the auxiliary block 202 away from each other. The reinforcing ring 6 can increase the fixed connection area between the electric telescopic rod 203 and the auxiliary block 202, so that the connection relationship between the two parties is more firm, preventing the possibility of breakage at the connection after long-term use, and increasing the firmness of the device.
[0026] A clamping block 205 is slidably connected to the inside of each moving block 204. Two auxiliary telescopic rods 206 are fixedly connected to the side surface of each of the two clamping blocks 205 away from each other. One ends of each group of auxiliary telescopic rods 206 away from each other are fixedly connected to the inner wall of the moving block 204. Two groups of connecting blocks 7 are fixedly connected to the bottom surface of the placement rack 1. A moving wheel 8 is rotatably connected to the inside of each group of connecting blocks 7. By using the cooperation of the connecting block 7 and the moving wheel 8, the ability to move the device conveniently can be achieved, and at the same time, it can also be quickly deflected during the movement, increasing the convenience of the device.
[0027] A pressure sensor 207 is fixedly connected to the inner wall of each moving block 204. Each pressure sensor 207 is electrically connected to the electric telescopic rod 203 through a wire. A pressure measuring spring 208 is fixedly connected to one end of each pressure sensor 207 close to each other. One end of each of the two pressure measuring springs 208 close to each other is fixedly connected to the side surface of the clamping block 205 away from each other. Two auxiliary handles 9 are fixedly connected to the inner wall of the placement rack 1. An anti-slip sleeve 10 is fixedly connected to the outer surface of each auxiliary handle 9. The cooperation of the auxiliary handle 9 and the anti-slip sleeve 10 can provide a good force application point for the placement rack 1, increasing the convenience when the placement rack 1 needs to be pushed. The anti-slip sleeve 10 can increase the firmness when grasping the auxiliary handle 9.
[0028] A first rubber pad 209 is fixedly connected to the side surface of each of the two clamping blocks 205 close to each other. A plurality of rotating cylinders 210 arranged at equal distances are rotatably connected to the inside of the placement rack 1. A second rubber pad 211 is fixedly connected to the outer surface of each rotating cylinder 210. Two firmness rings 11 are fixedly connected to the outer surface of each auxiliary handle 9. The bottom end of each group of firmness rings 11 is fixedly connected to the inner wall of the placement rack 1. The firmness rings 11 can increase the fixed connection area between the auxiliary handle 9 and the placement rack 1, thereby making the connection relationship between the two more firm, preventing the possibility of breakage at the connection after long-term use, and increasing the firmness of the device.
[0029] The working principle of the present utility model is as follows: When in use, first connect the power supply to the electric telescopic rod 203 and the pressure sensor 207. When the device needs to be used, first place the shielding door in the placement rack 1, then rotate the fixing bolt 5 to move it out of the placement rack 1, adjust the height of the adjusting block 201 to an appropriate position, then insert the fixing bolt 5 back into one of the limit holes 4, and then start the electric telescopic rod 203. Use the power generated by the electric telescopic rod 203 to drive the moving block 204 to move, thereby driving the clamping block 205 to move, and rely on the two clamping blocks 205 to clamp the front and back of the shielding door. The first rubber pad 209 can increase the protection during clamping. At the same time, during the clamping process of the shielding door by the clamping block 205, the clamping block 205 will retract into the moving block 204 through the cooperation of the auxiliary telescopic rod 206 and compress the pressure measuring spring 208 itself. At this time, the pressure sensor 207 can continuously detect the current pressure value of the pressure measuring spring 208, and when the pressure value reaches the preset value, it will send an electrical signal to the electric telescopic rod 203 through the wire to make it stop, so as to accurately control the pressure value during clamping and avoid the situation of damaging the shielding door due to too large or too small pressure value. When the device needs to be moved, push the auxiliary handle 9. The anti-slip sleeve 10 can improve the firmness when grasping the auxiliary handle 9, and then move the placement rack 1 through the cooperation of the connecting block 7 and the moving wheel 8. When the shielding door needs to be taken out, start the electric telescopic rod 203 to drive the clamping blocks 205 to move away from each other, and pull the shielding door. At this time, relying on the rotation of the rotating cylinder 210 itself, the shielding door can be conveniently taken out. At the same time, the second rubber pad 211 can improve the safety when the shielding door moves, effectively improving the use effect of the subway shielding door installation positioning auxiliary frame.
