[0002] Escalators and moving walkways, as indispensable means of transportation in modern urban life, play an important role in public places such as shopping malls, airports, and subway stations due to their efficiency and convenience. However, with the increasing frequency of their use, safety issues have gradually emerged, especially the safety protection of children, which has become a key issue that urgently needs to be addressed.

[0003] Children, due to their young age, strong curiosity, and limited ability to recognize and judge danger, often unconsciously engage in dangerous behaviors when riding escalators or moving walkways. For example, they may put their hands into the gap between the handrail and the bottom of the escalator. This behavior can easily lead to their hands being caught, causing serious injuries and placing a significant burden on families and society. Therefore, we have developed an escalator anti-pinch hand device to address this issue. Summary of the Invention

Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.

[0031] As described in the background art, children, due to their young age, strong curiosity, and limited ability to recognize and judge danger, often unconsciously engage in dangerous behaviors when riding escalators or moving walkways, such as putting their hands into the gap between the handrail and the bottom entrance of the escalator. This behavior can easily lead to their hands being caught, causing serious pinching injuries and placing a great burden on families and society.

[0032] To solve this technical problem, this utility model provides an escalator anti-pinch hand device.

[0033] For details, please refer to Figures 1-3 The escalator anti-pinch device specifically includes:

[0034] The protective seat 1 has an arc-shaped groove 3 and a clearance opening 101 connected to the arc-shaped groove 3 on one side. The bottom of one side of the protective seat 1 has a latch 102, which is connected to the clearance opening 101 and the arc-shaped groove 3. The arc-shaped groove 3 is used for the protection of the handrail entrance.

[0035] The escalator anti-pinch device provided by this utility model can physically isolate the entrance and exit of the handrail by setting the protective seat 1, effectively reducing the chance of children's hands approaching or reaching into the handrail entrance and exit of the bottom of the escalator or moving walkway, thereby significantly reducing the incidence of safety accidents caused by pinching hands.

[0036] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.

[0037] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.

[0038] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.

[0039] Example 1, please refer to Figures 1-3 An escalator anti-pinch device includes a protective seat 1. One side of the protective seat 1 has an arc-shaped groove 3 and a clearance opening 101 communicating with the arc-shaped groove 3. The bottom of one side of the protective seat 1 has a latch 102, which communicates with the clearance opening 101 and the arc-shaped groove 3. The arc-shaped groove 3 is used for protection of the handrail entrance and exit. The protective seat 1 provided in this application can physically isolate the handrail entrance and exit, effectively reducing the likelihood of children's hands approaching or reaching into the handrail entrance and exit of the bottom of the escalator or moving walkway, thereby significantly reducing the incidence of safety accidents caused by pinching hands.

[0040] Furthermore, such as Figures 1-2 As shown, the protective seat 1 is provided with first fixing bolts 103 on both sides. The end of the first fixing bolt 103 passes through the protective seat 1 and extends into the bayonet 102. It is inserted into the escalator base through the bayonet 102 and then fixed by the first fixing bolt 103 to realize the installation of the protective seat 1.

[0041] Example 2 further optimizes the escalator anti-pinch device provided in Example 1, specifically, as follows: Figures 1-2 As shown, the top of the protective seat 1 has two sliding grooves 2, which are located on both sides of the clearance opening 101. Each of the two sliding grooves 2 is equipped with a protective component, which is used to protect the gap between the clearance opening 101 and the escalator protective glass.

[0042] Furthermore, such as Figures 1-2 As shown, the protective component includes a first baffle 201 slidably connected in the slide groove 2. A second fixing bolt 202 is connected between the first baffle 201 and the protective seat 1. The first baffle 201 can be fixed by the second fixing bolt 202. The first baffle 201 can seal and protect the gap between the clearance opening 101 and the escalator protective glass, so as to reduce the possibility of children inserting their fingers into the gap between the clearance opening 101 and the escalator protective glass.

[0043] Furthermore, such as Figures 1-2As shown, an arc-shaped groove plate 301 is slidably connected inside the arc-shaped groove 3. A cleaning cloth 302 is installed on the inner wall of the arc-shaped groove plate 301. The cleaning cloth 302 is used to contact the outer surface of the handrail to clean the outer surface of the handrail.

[0044] Furthermore, the protective seat 1 is provided with a fixing component, which is used to fix the position of the arc-shaped groove plate 301.

[0045] Furthermore, such as Figures 1-2 As shown, the fixing component includes a third fixing bolt 304 set on the protective seat 1. One end of the third fixing bolt 304 passes through the arc-shaped placement groove 3 and contacts the arc-shaped groove plate 301. The third fixing bolt 304 can fix the position of the arc-shaped groove plate 301. After loosening the third fixing bolt 304, the arc-shaped groove plate 301 can be rotated upward to remove the arc-shaped groove plate 301, so as to facilitate cleaning of the cleaning cloth 302.

[0046] Furthermore, such as Figures 1-2 As shown, a groove 303 is provided on the side of the protective seat 1, and the outer end of the third fixing bolt 304 is located in the groove 303. The groove 303 is used to accommodate the third fixing bolt 304.

[0047] Furthermore, such as Figure 1 As shown, a second baffle 203 is fixedly connected to the top of the first baffle 201. The end of the second baffle 203 away from the first baffle 201 extends between the arc-shaped placement groove 3 and the cleaning cloth 302. The second baffle 203 can further protect the gap between the arc-shaped placement groove 3 and the escalator safety glass.

[0048] Example 3 further optimizes the escalator anti-pinch device provided in Example 1 or 2, specifically, as follows: Figure 3 As shown, a player 4 and a human body sensor 5 are installed on the side of the protective seat 1 away from the gate 102. A controller is connected between the player 4 and the human body sensor 5. The human body sensor 5 can detect whether anyone is approaching the side of the protective seat 1 away from the gate 101. If someone approaches, the player 4 will play a warning audio to remind the child to stay away.

[0049] The usage process of the escalator anti-pinch device provided by this utility model is as follows:

[0050] For ease of description and understanding, this application uses D to represent the escalator base, B to represent the escalator safety glass, and A to represent the handrail. Figure 4Mark the location, unscrew the second fixing bolt 202 to remove the first baffle 201, insert the bayonet 102 into the escalator base and tighten the first fixing bolt 103 to fix the protective seat 1. At this time, the handrail is inserted into the cleaning cloth 302 through the clearance opening 101 and contacts the inner wall of the cleaning cloth 302. The gap between the handrail and the arc-shaped groove plate 301 is less than 6 mm to prevent children's fingers from being inserted. Fix the first baffle 201 in the slide groove 2 with the second fixing bolt 202. The first baffle 201 covers the gap between the protective seat 1 and the escalator protective glass.
