[0020] In one embodiment, Figure 1-4 As shown, a rail transit screen door support device includes a base 1, a bearing plate 2 is provided on the top of the base 1, a screen door body 3 is fixedly connected to the top surface of the bearing plate 2, support plates 4 are fixedly connected to the left and right sides of the bottom surface of the bearing plate 2, the support plate 4 is arranged in the inner cavity of the base 1, the bottom surface of the support plate 4 is in contact with the top surface of the inner wall of the base 1, slots 5 are provided on the facing surfaces of the two support plates 4 near the top, fixed plates 6 are fixedly connected to the left and right sides of the bottom surface of the inner wall of the base 1, the fixed plate 6 is arranged between the two support plates 4, the facing surfaces of the two fixed plates 6 are commonly bearing-connected with a bidirectional screw 7, both ends of the surface of the bidirectional screw 7 are threadedly sleeved with movable plates 8, the separated surfaces of the two movable plates 8 and near the top are fixedly connected with plug plates 9, and the two plug plates 9 are respectively plugged into adjacent slots 5 on the sides away from the movable plates 8.

[0021] In order to facilitate the rotation of the bidirectional screw 7, a driven bevel gear 10 is fixedly sleeved in the middle of the surface of the bidirectional screw 7, a movable hole is opened in the middle of the front side of the base 1, and a rotating rod 11 is movably sleeved in the movable hole. The two ends of the rotating rod 11 respectively penetrate the inner and outer sides of the base 1, and the rear end face of the rotating rod 11 is fixedly connected with a driving bevel gear 12. The driving bevel gear 12 and the driven bevel gear 10 are meshed with each other, and the front end face of the rotating rod 11 is fixedly connected with a handle 13.

[0022] In order to limit the movable plate 8 so that the movable plate 8 does not rotate with the bidirectional screw 7, a slide groove 14 is opened in the middle of the bottom surface of the inner wall of the base 1, and the bottom surfaces of the two movable plates 8 are fixedly connected with sliders 15, and the bottoms of the two sliders 15 are slidably connected to the left and right sides of the slide groove 14 respectively.

[0023] In order to ensure that the shielding door body 3 is located in the middle of the base 1 after the support plate 4 is placed in the base 1, positioning blocks 16 are fixedly connected to the left and right sides of the bottom surface of the base 1, and the two fixed plates 6 are arranged between the two positioning blocks 16. Positioning grooves 17 are opened at the bottom of the two support plates 4, and the two positioning blocks 16 are respectively inserted into adjacent positioning grooves 17.

[0024] In order to conveniently fix the base 1 on the ground, mounting plates 18 are fixedly connected to the left and right sides of the surface of the base 1 and at the bottom, and each mounting plate 18 is provided with assembly holes 19 on the front and rear sides.

[0025] In order to allow the carrying plate 2 and the supporting plate 4 to enter the base 1 , a mounting opening 20 is provided in the middle of the top of the base 1 , and the carrying plate 2 is movably sleeved in the mounting opening 20 .

[0026] Working principle: When the utility model is used, firstly, the handle 13 is twisted to rotate the rotating rod 11, the rotating rod 11 drives the active bevel gear 12 to rotate, the active bevel gear 12 drives the driven bevel gear 10 to rotate, the driven bevel gear 10 drives the bidirectional screw 7 to rotate, so that the two movable plates 8 move toward each other, the movable plate 8 drives the plug plate 9 to move, so that the two plug plates 9 are pulled out from the two slots 5 respectively, and the fixation of the support plate 4 is released. At this time, the shielding door body 3 is pulled upward, so that the bearing plate 2 and the support plate 4 are moved out of the base 1 through the installation opening 20, and the shielding door body 3 can be removed from the base 1. When installing the shielding door body 3, firstly, the bearing plate 2 and the support plate 4 are placed into the base 1 through the installation opening 20, so that the two positioning blocks 16 are respectively inserted into the two support blocks The positioning groove 17 on the support plate 4 is used to limit the left and right movement of the shielding door body 3, and at the same time, the shielding door body 3 is located in the middle of the base 1, and then the handle 13 is twisted in the opposite direction to make the rotating rod 11 rotate in the opposite direction, thereby driving the bidirectional screw 7 to rotate in the opposite direction. The bidirectional screw 7 rotates in the opposite direction to make the two movable plates 8 move away from each other, and the movable plate 8 drives the plug plate 9 to move, so that the two plug plates 9 are respectively inserted into the two slots 5, and the support plate 4 is fixed, so that the support plate 4 cannot move upward, thereby fixing the shielding door body 3, and completing the installation of the shielding door body 3. Through the above method, the shielding door body 3 can be disassembled and installed on the base 1. When the shielding door body 3 needs to be replaced, there is no need to replace the entire device. The disassembly and assembly are simple and the replacement cost is reduced.

[0027] The technical features of the above embodiments may be combined arbitrarily. To make the description concise, not all possible combinations of the technical features in the above embodiments are described. However, as long as there is no contradiction in the combination of these technical features, they should be considered to be within the scope of this specification.

[0028] The above embodiments only express several implementation methods of the utility model, and the descriptions are relatively specific and detailed, but they cannot be understood as limiting the scope of the utility model patent. It should be pointed out that for ordinary technicians in this field, several modifications and improvements can be made without departing from the concept of the utility model, which all belong to the protection scope of the utility model. Therefore, the protection scope of the utility model patent shall be based on the attached claims.
