[0033] Refer to Figure 1 , Figure 4 , quick release assembly 4 includes indicating board 41, indicating board 41 is transparent plastic material, the inner wall of indicating board 41 is elastically connected with clamping block 43 through compression spring 42, the right surface of indicating board 41 is provided with slot 401, warning sign with warning slogan can be inserted from slot 401, the front surface of support 1 is provided with arc slot 402, arc slot 402 is provided with two groups, and symmetrically distributed at the left and right ends of the front surface of indicating board 41, the finger can be inserted into arc slot 402 and warning sign contact, convenient for the replacement of warning sign.

[0034] Refer to Figure 1 - Figure 3The sealing tube 31 is fixedly connected to the inner wall of the bracket 1. The suction cup 32 penetrates and is fixedly connected to the lower surface of the bracket 1. The one-way valve 33 penetrates the front surface of the bracket 1. The valve core 34 penetrates the left surface of the bracket 1. The connecting block 37 penetrates and is slidably connected to the right surface of the bracket 1, and moves longitudinally.

The connecting rod 36 penetrates and is piston-connected to the upper surface of the sealing tube 31, which can maintain the seal inside the sealing tube 31.

[0035] Reference Figure 1 , Figure 4 The indicator plate 41 is fitted onto the outer wall of the isolation device 2. The indicator plate 41 is U-shaped with the opening facing downwards. It can be moved downwards to fit onto the isolation strip on the isolation device 2. One end of the compression spring 42 is fixedly connected to the inner wall behind the indicator plate 41, and the other end of the compression spring 42 is fixedly connected to the rear surface of the locking block 43. The locking block 43 is slidably connected to the inner wall of the indicator plate 41. When the locking block 43 moves backwards, it will squeeze the compression spring 42 to generate a reaction force. The top and bottom ends of the front surface of the locking block 43 are both set as inclined surfaces. During the fitting process, the inclined surfaces of the locking block 43 will be squeezed by the isolation strip, which will drive the locking block 43 to move backwards and release the obstruction. The slot 401 and the arc groove 402 are connected.

[0036] Working principle: First, place the device at the designated location on the ground of the rail transit platform. Since the lower surface of the suction cup 32 is slightly lower than the lower surface of the bracket 1, and the part exceeding it is made of deformable rubber, the suction cup 32 adheres tightly to the ground under its own weight. At this time, the air inside the sealing tube 31 is in a normal state.

[0037] At this time, the moving ring 38 can be moved upward to drive the connecting block 37 to move upward. The connecting block 37 drives the connecting rod 36 and the sealing gasket 35 to move upward in the sealing tube 31. The upward movement of the sealing gasket 35 will squeeze the air in the upper part of the sealing tube 31 to be discharged from the one-way valve 33. It will also increase the space in the lower part of the sealing tube 31 and reduce the air pressure. While the external atmospheric pressure remains unchanged, the suction cup 32 will tightly adhere to the ground under the action of the air pressure difference, thereby enhancing the friction and adhesion between the support 1 and the ground. This effectively prevents the support 1 from easily moving or tipping over due to external forces (such as collisions with people or airflow impacts caused by train movement), ensuring the stability of the device.

[0038] When the device needs to be moved, press the valve on the valve core 34 to allow air inside and outside the sealing tube 31 to flow through the valve core 34, the air pressure inside the sealing tube 31 returns to normal, and the suction cup 32 returns to its initial state, at which point the device can be moved easily.

[0039] In addition, when the device is used, the indicating plate 41 can be sleeved on the isolation belt, in the sleeving process, the isolation belt extrudes the inclined surface of the front surface of the clamping block 43, so that the clamping block 43 moves backward and extrudes the compression spring 42 to generate a reaction force, after the indicating plate 41 is sleeved, the clamping block 43 is reset forward under the elastic force of the compression spring 42 to position the indicating plate 41, the indicating plate 41 will remain stable without external force, and when used, the warning board with warning slogans can be inserted from the slot 401, when it is needed to be taken down, the indicating plate 41 can be pulled upward by force, in the upward movement, the inclined surface of the clamping block 43 is extruded, and then moves backward to release the blockage.

[0040] Finally, it should be noted that: the above only for the preferred embodiments of the utility model, and does not limit the utility model, although the utility model has been described in detail with reference to the foregoing embodiments, for the person skilled in the art, it still can modify the technical scheme recorded in the foregoing each embodiment, or equivalent replacement to part of technical features, any modification, equivalent replacement, improvement etc. that is made within the spirit and principle of the utility model, should be included in the protection scope of the utility model.
