Detailed Implementation

[0019] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0020] Please see Figure 1-3 This utility model provides a technical solution:

[0021] In this technical solution, an anti-climbing handrail device for an escalator includes a trapezoidal plate 1 and a side plate 2. There are two trapezoidal plates 1, and the side plate 2 is bonded between the two trapezoidal plates 1. An adsorption mechanism 3 is installed on the lower wall of the side plate 2, and the adsorption mechanism 3 can adsorb onto the outside of the escalator.

[0022] The adsorption mechanism 3 includes a fixed cylinder 31, a connecting sleeve 32, a clearance hole 33, a suction cup 34, and an air extraction pipe 35. The fixed cylinder 31 is inserted and installed on the lower wall of the side plate 2. The connecting sleeve 32 is inserted and installed on the upper wall of the fixed cylinder 31. The clearance hole 33 is opened on the lower wall of the fixed cylinder 31. The lower wall of the connecting sleeve 32 passes through the clearance hole 33 and the suction cup 34 is installed. The suction cup 34 can be adsorbed on the outer side wall of the external escalator. One end of the air extraction pipe 35 is sleeved on the outer side of the upper end of the connecting sleeve 32. The other end of the air extraction pipe 35 passes through the side wall of the side plate 2. The air extraction pipe 35 is connected to the inner cavity of the suction cup 34.

[0023] In this technical solution, the device is installed on the side wall of the external escalator by suction cup 34 in the adsorption mechanism 3, which makes the installation more convenient and eliminates the need to make holes in the escalator, making it more aesthetically pleasing.

[0024] In addition, by setting up the air extraction pipe 35, an external vacuum pump can be connected to the air extraction pipe 35 to extract the air inside the suction cup 34, so as to form a vacuum inside it, thereby improving the adsorption stability of the suction cup 34.

[0025] In some technical solutions, a sliding ring 4 is slidably installed inside the fixed cylinder 31, and a rubber sleeve 5 is installed on the lower wall of the sliding ring 4. The rubber sleeve 5 passes through the lower wall of the fixed cylinder 31 through the clearance hole 33. The rubber sleeve 5 is sleeved on the outside of the suction cup 34. A spring 6 is sleeved on the outer wall of the connecting sleeve 32. One end of the spring 6 is in contact with the inner wall of the fixed cylinder 31, and the other end of the spring 6 is in contact with the upper wall of the sliding ring 4.

[0026] In this technical solution, the rubber sleeve 5 can cover the suction cup 34, thereby preventing external dust from contacting the suction cup 34 and thus preventing the suction cup 34 from not adhering properly due to excessive dust.

[0027] In some technical solutions, an adapter 7 is installed at one end of the suction pipe 35 located outside the side plate 2. The adapter 7 includes a sleeve 71, a fixing ring 72, a return spring 73, and a blocking plate 74. The sleeve 71 is sleeved on the outside of the suction pipe 35. The fixing ring 72 is installed on the inner side wall of the sleeve 71. One end of the return spring 73 is installed on the side wall of the fixing ring 72. The blocking plate 74 is installed on the other end of the return spring 73. The blocking plate 74 can block the suction pipe 35.

[0028] In this technical solution, the adapter 7 described herein can be regarded as a simple one-way valve. When the adapter 7 is connected to the external vacuum pump, the vacuum pump draws air to the outside. During this process, the blocking plate 74, under the action of suction, releases the blockage on the suction pipe 35, creating a vacuum state inside its suction cup 34, which firmly adheres to the side wall of the external escalator. After the air is drawn, when the vacuum pump is disconnected from the adapter 7, the blocking plate 74 will instantly block the suction pipe 35 under the action of the return spring 73.

[0029] In some technical solutions, a sealing gasket 8 is fitted to the side wall of the blocking plate 74, and the sealing gasket 8 can be inserted into the suction pipe 35.

[0030] In this technical solution, the sealing performance at the connection between the plug plate 74 and the extraction pipe 35 can be improved by setting the sealing gasket 8.

[0031] In some technical solutions, the side wall of the trapezoidal plate 1 is provided with a through groove 9, and a rubber pad 10 is fitted to the inner wall of the through groove 9.

[0032] In this technical solution, the through groove 9, once opened, forms a handle, making it convenient for workers to hold and move the device. The rubber pad 10 makes it more comfortable for workers to lift the device.

[0033] In some technical solutions, warning signs 11 are attached to the side walls of both the trapezoidal plate 1 and the side plate 2.

[0034] In this technical solution, the warning sign 11 can serve as a warning to pedestrians. The warning sign in the warning sign 11 mentioned in this article is "No climbing".

[0035] Working principle: The operator places the device on the inclined surface outside the escalator, so that its suction cup 34 is attached to the side wall of the escalator. Then, the device is pressed down to initially fix it. Then, the vacuum pump is connected to the adapter 7. The vacuum pump starts to draw air outward. During this process, the blocking plate 74, under the action of suction, releases the blockage of the air extraction pipe 35, allowing the air in the suction cup 34 to be drawn out. A vacuum state is formed inside the suction cup 34, which is firmly attached to the side wall of the external escalator. After the air extraction is completed, when the vacuum pump is disconnected from the adapter 7, the blocking plate 74 will instantly block the air extraction pipe 35 under the action of the return spring 73.

[0036] Complete the installation of this device.
