It should be understood that the specific embodiments described here are only used to explain the utility model and are not used to limit the utility model.

[0028] Example

[0029] like Figure 1-5 As shown, a driving cab partition roller blind for subway drivers comprises a roller blind storage shell 1, a servo motor 2 is fixedly connected to one side of the roller blind storage shell 1, a winding shaft 3 is fixedly connected to the output end of the servo motor 2, a roller blind cloth 4 is fixedly connected to the outer circumferential surface of the winding shaft 3, a reinforcing rib 5 is fixedly connected to the back of the roller blind cloth 4, a metal fiber rope 6 is fixedly connected between adjacent reinforcing ribs 5, a pair of guide frames 7 are fixedly connected to the lower surface of the roller blind storage shell 1, the pair of guide frames 7 are arranged on both sides of the roller blind cloth 4, both ends of the reinforcing rib 5 extend into the guide frame 7, and a controller 9 is fixedly connected to one side of the guide frame 7;

[0030] The lower ends of the pair of guide frames 7 are fixedly connected with locking caps 71 , and one side of the lowermost reinforcing rib 5 is fixedly connected with a limiting mechanism 8 , and both ends of the limiting mechanism 8 are engaged with the locking caps 71 .

[0031] When in use, a plurality of horizontally distributed reinforcing ribs 5 are arranged on the back of the rolling curtain cloth 4, and adjacent reinforcing ribs 5 are connected by metal fiber ropes 6. The winding function of the partition rolling curtain composed of the rolling curtain cloth 4, reinforcing ribs 5 and metal fiber ropes 6 is not affected and can be wound normally. When the partition is used, the servo motor 2 is started, and the servo motor 2 will drive the winding shaft 3 to rotate in the extension direction. Then the lower end of the partition rolling curtain will automatically extend under the action of its own gravity, and finally be locked by the limiting mechanism 8. After the partition rolling curtain is extended, and under the limit of the guide frame 7, the reinforcing ribs 5 can remain stable. The reinforcing ribs 5 cooperate with the metal fiber ropes 6 to form a guardrail on the back of the rolling curtain cloth 4, which can greatly improve the protection effect on the driver in the cab and reduce safety hazards. At the same time, the front of the rolling curtain cloth 4 still takes into account the simple and beautiful design.

[0032] The wiring diagram of the servo motor 2 and the controller 9 in the present invention is common knowledge in the art, and its working principle is a known technology. The model is selected according to the actual use, so the control method and wiring arrangement of the servo motor 2 and the controller 9 are not explained in detail.

[0033] like Figure 2-3 As shown in Figure 5, the limiting mechanism 8 includes a shell 81, a circular connecting frame 82, a foot pedal 83, a pressure rod 84, a metal fiber rope 85, a latch 86 and a spring 87. The upper surface of the shell 81 is fixedly connected with the circular connecting frame 82, the upper end of the circular connecting frame 82 is embedded with the foot pedal 83, the lower end of the foot pedal 83 is fixedly connected with the pressure rod 84, both sides of the pressure rod 84 are fixedly connected with the metal fiber rope 85, one end of the metal fiber rope 85 is fixedly connected with the latch 86, one end of the latch 86 is engaged with the lock cap 71, the other end of the latch 86 is fixedly connected with the spring 87, and the spring 87 is fixed to the inner wall of the shell 81.

[0034] During use, when it is necessary to open the partition roller shutter as a whole, first step on the foot pedal 83, and the foot pedal 83 cooperates with the pressure rod 84 to drive the middle part of the metal fiber rope 85 to be pressed down. During the downward pressing process of the middle part of the metal fiber rope 85, the pins 86 at both ends will shrink and disengage from the lock cap 71. At the same time, the person starts the controller 9 with one hand. After the controller 9 starts the servo motor 2, the servo motor 2 will drive the winding shaft 3 to rotate in the winding direction. After the lower end of the partition roller shutter as a whole is lifted a short distance, release the foot pedal 83, and the servo motor 2 cooperates with the winding shaft 3 to automatically complete the winding of the partition roller shutter as a whole. The hands and feet work together to facilitate the operation and use of the person.

[0035] like Figure 5-6 As shown, a pair of through-core blocks 811 are fixedly connected to the inner top end of the outer shell 81 , and the metal fiber rope 85 passes through the through-core blocks 811 .

[0036] When in use, the middle part of the second metal fiber rope 85 can be lifted upwards through the through-core block 811 , so that the middle part of the second metal fiber rope 85 has a sufficient downward movement distance, thereby ensuring that the latch 86 can be retracted and separated from the lock cap 71 .

[0037] like Figure 5-6 As shown, the inner wall of the through-hole block 811 is rotatably connected to a pair of rollers 812 , and the metal fiber rope 85 is located between the pair of rollers 812 .

[0038] When in use, the friction between the through block 811 and the metal fiber rope 85 is reduced through the roller 812, thereby increasing the service life of the metal fiber rope 85.

[0039] like Figure 4 As shown, a pair of retaining frames 11 are fixedly connected to the inner wall of the roller blind storage housing 1, and the pair of retaining frames 11 are located at both ends of the winding shaft 3. The inner wall of the retaining frame 11 is fixedly connected to the bearing 12, and the inner wall of the bearing 12 is fixed to the outer circumferential surface of the winding shaft 3.

[0040] When in use, the two ends of the winding shaft 3 are fixed by the retaining frame 11 and the bearing 12, thereby improving the stability of the winding shaft 3 during operation.

[0041] like Figure 5 As shown, one end of the latch 86 is inclined.

[0042] When in use, after the lower end of the partition roller shutter extends downward to its full position by its own weight, since the weight of the lower end of the partition roller shutter is greater than the elastic force of the spring 87, the latch 86 can be automatically embedded in the lock cap 71, making it easier for personnel to operate.

[0043] In summary, the specific working process of this scheme is as follows: a plurality of horizontally distributed reinforcing ribs 5 are arranged on the back of the rolling curtain cloth 4, and the adjacent reinforcing ribs 5 are connected by a metal fiber rope 6. The winding function of the partition rolling curtain composed of the rolling curtain cloth 4, the reinforcing ribs 5 and the metal fiber rope 6 is not affected and can be wound normally. When the partition is used, the servo motor 2 is started, and the servo motor 2 will drive the winding shaft 3 to rotate in the extension direction. Then the lower end of the partition rolling curtain as a whole will automatically extend under the action of its own gravity, and finally locked by the limiting mechanism 8. After the partition rolling curtain as a whole is extended, and under the limit of the guide frame 7, the reinforcing ribs 5 can remain stable. The reinforcing ribs 5 cooperate with the metal fiber rope 6 to form a guardrail on the back of the rolling curtain cloth 4, which can greatly improve the protection effect on the driver in the cab and reduce safety hazards. At the same time, the front of the rolling curtain cloth 4 still takes into account the simple and beautiful design.

[0044] Among them, when it is necessary to open the partition roller shutter as a whole, first step on the foot pedal 83, and the foot pedal 83 cooperates with the pressure rod 84 to drive the middle part of the metal fiber rope 85 to be pressed down. During the downward pressing process of the middle part of the metal fiber rope 85, the pins 86 at both ends will shrink and disengage from the lock cap 71. At the same time, the person starts the controller 9 with one hand. After the controller 9 starts the servo motor 2, the servo motor 2 will drive the winding shaft 3 to rotate in the winding direction. After the lower end of the partition roller shutter as a whole is lifted a short distance, release the foot pedal 83, and the servo motor 2 cooperates with the winding shaft 3 to automatically complete the winding of the partition roller shutter as a whole. The hands and feet work together to facilitate the operation and use of the person.

[0045] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
