[0042] Please refer to Figures 1 to 3 , the utility model discloses an automatic escalator or automatic sidewalk's turnover type apron 20 mechanism, comprising: cover plate 10, apron 20 and apron 30.

[0043] Cover plate 10, apron 20 and apron 30 are arranged in order from top to bottom, and cover plate 10, apron 20 and apron 30 are all used for being installed at the side of the circulating transport device of the automatic escalator or automatic sidewalk, and the access hole 11 is formed between cover plate 10 and apron 30. Apron 20 can be rotatably connected with cover plate 10 or apron 30.

[0044] When the wall protection plate 20 is rotationally matched with the cover plate 10, the wall protection plate 20 can be opened or closed to the access hole 11. When the wall protection plate 20 is closed to the access hole 11, the wall protection plate 20 is locked with the cover plate 10 through the locking structure 21. When the wall protection plate 20 is opened to the access hole 11, the wall protection plate 20 can be rotated upward to the top plate of the cover plate 10. The wall protection plate 20 can be opened to the state of the access hole 11 by the gravity of the wall protection plate 20, or the wall protection plate 20 can be maintained in the state of the opened access hole 11 by the design of the rotation structure of the wall protection plate 20 and the cover plate 10. In the embodiment, the wall protection plate 20 is rotationally matched with the cover plate 10 through the rotation shaft and the shaft hole. The rotation shaft can be maintained from rotating relative to the shaft hole by the buckle or damping mechanism when the wall protection plate 20 is opened to the access hole 11. This is a technology known to those skilled in the art, and will not be described here.

[0045] When the wall protection plate 20 is rotationally matched with the cover plate 10, the wall protection plate 20 can be opened or closed to the access hole 11. When the wall protection plate 20 is closed to the access hole 11, the wall protection plate 20 is locked with the cover plate 10 through the locking structure 21. When the wall protection plate 20 is opened to the access hole 11, the wall protection plate 20 can be rotated upward to the top plate of the cover plate 10. The wall protection plate 20 can be opened to the state of the access hole 11 by the gravity of the wall protection plate 20, or the wall protection plate 20 can be maintained in the state of the opened access hole 11 by the design of the rotation structure of the wall protection plate 20 and the cover plate 10. In the embodiment, the wall protection plate 20 is rotationally matched with the cover plate 10 through the rotation shaft and the shaft hole. The rotation shaft can be maintained from rotating relative to the shaft hole by the buckle or damping mechanism when the wall protection plate 20 is opened to the access hole 11. This is a technology known to those skilled in the art, and will not be described here.

[0046] Since the wall protection plate 20 can be easily opened to the access hole 11, it is convenient for the staff to carry out maintenance. The wall protection plate 20 does not need to be moved to the horizontal position, which simplifies the operation and improves the maintenance efficiency.

[0047] When the wall protection plate 20 is closed to the access hole 11, the locking structure 21 locks the wall protection plate 20 to avoid the movement of the wall protection plate 20.

[0048] Please refer to Figure 4 In some optional embodiments, when the wall protection plate 20 is rotationally matched with the cover plate 10, the anti-pinch strip 12 is arranged between the cover plate 10 and the wall protection plate 20. The anti-pinch strip 12 shields the gap between the cover plate 10 and the wall protection plate 20. Since the wall protection plate 20 and the cover plate 10 need to be rotated, there will be a gap between the cover plate 10 and the wall protection plate 20. The anti-pinch strip 12 can shield and protect the gap to prevent the passengers or staff from being pinched. In addition, the anti-pinch strip 12 can also improve the appearance. The anti-pinch strip 12 can be installed on the cover plate 10 by pasting, locking by a threaded part 211, or buckling.

[0049] In some optional embodiments, the anti-pinch strip 12 comprises a fixed portion 121 and a shielding portion 122 connected with each other, the fixed portion 121 is installed on the top of the cover plate 10, and the shielding portion 122 is located on one side of the cover plate 10 and extends downward, and the shielding portion 122 shields the gap formed between the cover plate 10 and the apron plate 20. In this embodiment, the fixed portion 121 is attached to the cover plate 10 by means of a gel.

[0050] Since the shielding portion 122 needs to be as close as possible or in close contact with the apron plate 20 to improve the shielding and protection effect, it may hinder the rotation of the apron plate 20. Therefore, the shielding portion 122 is elastically connected with the fixed portion 121, or the shielding portion 122 has elasticity. When the apron plate 20 is opened to access the access opening 11, the apron plate 20 presses against the shielding portion 122 and drives the shielding portion 122 to elastically deform or drives the connection between the shielding portion 122 and the fixed portion 121 to elastically deform, so that the shielding portion 122 can adapt to the rotation of the apron plate 20 through elastic deformation, and the shielding portion 122 is prevented from hindering the rotation of the apron plate 20. In this embodiment, the fixed portion 121 and the shielding portion 122 are integrally formed and made of rubber material, which is convenient for production and installation, and the rubber material also has elasticity, which meets the elastic requirement of the shielding portion 122. Of course, in other embodiments, the fixed portion 121 and the shielding portion 122 can also be made of other suitable materials and structures, for example, the fixed portion 121 and the shielding portion 122 are made of metal sheets, the fixed portion 121 and the shielding portion 122 are rotatably connected, and a torsion spring is connected between the fixed portion 121 and the shielding portion 122. The rotation of the apron plate 20 drives the shielding portion 122 to move, which causes the torsion spring to elastically deform, and the like is not limited.

[0051] In some optional embodiments, when the apron plate 20 is rotationally matched with the cover plate 10, the top or other suitable position of the apron plate 30 is provided with a stop portion 31, and when the apron plate 20 closes the access opening 11, the apron plate 20 abuts against the stop portion 31 to limit the rotation of the apron plate 20, and the stop portion 31 can stabilize the apron plate 20 to close the access opening 11. In this embodiment, the locking structure 21 locks the apron plate 20 on the stop portion 31. Since the top of the apron plate 20 is connected with the cover plate 10, and the position close to the bottom of the apron plate 20 is locked on the stop portion 31, the apron plate 20 can be stably fixed and is not easy to move.

[0052] In some optional embodiments, when the apron plate 20 closes the access opening 11, the apron plate 20 is inclined relative to the horizontal plane, so that the apron plate 20 relies on the dead weight to press against the stop portion 31, thereby improving the position stability of the apron plate 20 and avoiding the apron plate 20 from shaking and deviating from the position.

[0053] In some optional embodiments, the locking structure 21 comprises a plurality of threaded members 211.

[0054] When the wall protection plate 20 is rotationally matched with the cover plate 10 and the wall protection plate 20 closes the access hole 11, the wall protection plate 20 is locked with the skirt plate 30 through the threaded member 211;

[0055] When the wall protection plate 20 is rotationally matched with the skirt plate 30 and the wall protection plate 20 closes the access hole 11, the wall protection plate 20 is locked with the cover plate 10 through the threaded member 211.

[0056] In the embodiment, the wall protection plate 20 is locked on the stop portion 31 of the skirt plate 30 through a screw. The threaded member 211 is used to facilitate the disassembly and assembly of the wall protection plate 20, and the stable locking of the wall protection plate 20 is also achieved. Of course, the locking of the wall protection plate 20 with the skirt plate 30 can also be achieved through a latch structure, a buckle structure, etc., and is not limited to the example.

[0057] Please refer to Figure 5 and Figure 6 In some optional embodiments, the locking structure 21 further comprises a plurality of spring nut 212, and the spring nut 212 has a spring portion 213 and a nut portion 214 connected with each other.

[0058] When the wall protection plate 20 is rotationally matched with the cover plate 10 and the wall protection plate 20 closes the access hole 11, the spring portion 213 and the nut portion 214 clamp the skirt plate 30 to enable the spring nut 212 to be installed on the skirt plate 30, and the threaded member 211 is threadedly matched with the nut portion 214;

[0059] When the wall protection plate 20 is rotationally matched with the skirt plate 30 and the wall protection plate 20 closes the access hole 11, the spring portion 213 and the nut portion 214 clamp the cover plate 10 to enable the spring nut 212 to be installed on the cover plate 10, and the threaded member 211 is threadedly matched with the nut portion 214.

[0060] In the embodiment, the spring nut 212 is arranged on the stop portion 31 of the skirt plate 30. The spring portion 213 and the nut portion 214 are clamped on the stop portion 31, and the elastic force of the spring portion 213 enables the spring nut 212 to be stably fixed on the stop portion 31. The specific structure of the spring nut 212 is known to those skilled in the art, and will not be described here. The wall protection plate 20 is locked on the stop portion 31 of the skirt plate 30 through the threaded matching of the threaded member 211 and the nut portion 214, thereby achieving strong locking and avoiding the wall protection plate 20 from being opened.

[0061] Please refer to Figure 3 and Figure 7In some optional embodiments, the position detector 13 is arranged on the cover plate 10 or the skirt plate 30, and the position detector 13 is inductively matched with the guard plate 20. When the guard plate 20 is not in the closed position due to accidental opening, the position detector 13 will send an alarm signal, which can be transmitted to the terminal of the staff or other equipment, so as to conveniently remind the staff. In the embodiment, the position detector 13 is arranged on the cover plate 10.

[0062] The specific structure of the position detector 13 can be selected according to actual needs, for example, the position detector 13 can adopt a proximity switch, a photoelectric sensor, an infrared sensor, etc. The proximity switch, the photoelectric sensor, the infrared sensor, etc. can be inductively matched with the guard plate 20, which is not limited to this example. The detection principle of the proximity switch, the photoelectric sensor, the infrared sensor, etc. is known to those skilled in the art, and will not be described here. In some optional embodiments, the position detector 13 includes at least one laser sensor arranged on the cover plate 10 or the skirt plate 30. At least one side of the guard plate 20 is provided with a corresponding arrangement of the reflection shield 22 corresponding to the laser sensor. When the guard plate 20 closes the access hole 11, the reflection shield 22 is located within the sensing range of the laser sensor. When the guard plate 20 opens the access hole 11, the reflection shield 22 is moved due to the rotation of the guard plate 20, so that the reflection shield 22 is located outside the sensing range of the laser sensor. At this time, the laser sensor can send an alarm signal. Since the guard plate 20 has a large volume and has a certain toughness or elasticity, there may be a situation that one side of the guard plate 20 is raised. Preferably, in the embodiment, the reflection shield 22 is arranged on both sides of the guard plate 20, and two laser sensors are correspondingly arranged on the cover plate 10 or the skirt plate 30. The laser sensor and the reflection shield 22 are inductively matched one by one.

[0063] The above-mentioned turnover guard plate 20 mechanism of the escalator or moving sidewalk can be applied to an escalator or moving sidewalk, which includes the above-mentioned turnover guard plate 20 mechanism of the escalator or moving sidewalk. In the embodiment, the escalator is taken as an example for description. The circulating conveying device of the escalator usually includes a plurality of steps that move in a cycle under the driving of a chain conveyor. People can stand on the steps. The cover plate 10, the guard plate 20 and the skirt plate 30 are arranged in sequence from top to bottom on one side of the steps. The skirt plate 30 is used for anti-pinch, and the cover plate 10 and the guard plate 20 are used for protecting people and other functional parts of the escalator. The cover plate 10 is usually provided with a circulating handrail.

[0064] Although the embodiments of the present application have been shown and described, it is to be understood that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present application, the scope of which is defined by the appended claims and their equivalents.
