[0002] The existing escalator handrail cleaning tools are mainly divided into two categories: manual wiping tools and automatic cleaning equipment.

[0003] The automatic cleaning equipment cleans the escalator handrail through mechanized operation. Although it improves the cleaning efficiency, its high equipment cost, complex maintenance requirements, and the problem of space occupation caused by its large volume limit its practical application. Installing the automatic equipment on the escalator will occupy some space, affect the normal use of passengers, and even force passengers to stop using the escalator during the cleaning process, causing inconvenience.

[0004] The manual wiping tool usually consists of a skeleton and a wiping cloth fixed on the skeleton. In order to prevent the wiping cloth from moving during the cleaning process, connectors such as magic tapes and snap buttons are often used to fix it on the skeleton. However, these connectors will lift the wiping cloth locally, making the wiping cloth unable to completely and tightly fit on the surface of the escalator handrail, resulting in an unsatisfactory cleaning effect and unable to completely remove dirt and bacteria. Summary of the Utility Model

For example, it can be a fixed connection, a detachable connection, or an integral connection; it can be directly connected, or indirectly connected through an intermediate medium, and can be the communication inside two components. For those of ordinary skill in the art, the specific meanings of the above terms in the present utility model can be understood according to specific circumstances.

[0031] As Figures 1 to 3 shown, in a schematic embodiment of the manual cleaning device for the escalator handrail 5 of the present utility model, the manual cleaning device for the escalator handrail 5 includes a main body skeleton plate 1 and a wiping cloth 2. One end of the wiping cloth 2 has an opening, and the main body skeleton plate 1 enters into the wiping cloth 2 through the opening, so that the wiping cloth 2 wraps the main body skeleton plate 1 inside it.

[0032] The wiping cloth 2 can be formed by sewing two cloth bodies, namely a first cloth body 21 and a second cloth body 22. After the wiping cloth 2 wraps around the main body skeleton plate 1, the first cloth body 21 and the second cloth body 22 are respectively located on the outer side and the inner side of the main body skeleton plate 1.

[0033] The inner surface of the first cloth body 21 is connected to the outer surface of the main body skeleton plate 1 through a magic tape 3.

[0034] The main body skeleton plate 1 includes a main body plate 11 and two side plates 12. The top ends of the two side plates 12 are respectively hinged to the two longitudinal ends of the main body plate 1. An inclined cut surface 13 is provided on the inner side of the end face at the top end of the side plate 12, and main cut surfaces 14 are provided on the lower sides of the longitudinal end faces of the main body plate 1. When the inclined cut surface 13 is attached to the corresponding main cut surface 14, the included angle between the side plate 12 and the main body plate 1 is less than 80 degrees, and torsion springs 4 are installed at the hinge joints of the side plate 12 and the main body plate 1.

[0035] When the manual cleaning device is in use, it is placed on the escalator handrail 5 from top to bottom. The main body plate 11 presses down on the middle part of the second cloth body 22, so that it completely fits on the upper surface of the escalator handrail 5. Driven by the torsion springs 4, the two side plates 12 on both sides swing inward, pressing the two side parts of the second cloth body 22 on the side surfaces on both sides of the escalator handrail 5. Hold the cleaning device by hand and move it along the escalator handrail 5, so that the wiping cloth 2 wipes and cleans the upper surface and the two side surfaces of the escalator handrail 5. The handrail 5 can be wiped and cleaned when the escalator is running. At this time, only need to hold the cleaning device to keep its position fixed, and the moving handrail 5 will move relative to the cleaning device to realize the wiping of the handrail 5.

[0036] Since the ends of the main plate 11 and the side plate 12 are provided with cut surfaces, and when the cut surfaces fit together, the side plate 12 is in a state of being tilted inward relative to the main plate 11, so that when the side plate 12 is perpendicular to the main plate 11, there is a gap between the ends of the two. The longitudinal width of the second cloth body 22 is greater than that of the first cloth body 21, so that the portion between the middle and side portions of the second cloth body 22 can extend outward or fold outward to form a connecting portion 24, and extend to the gap between the side panel 12 and the end portion of the main panel 11, and then when the torsion spring 4 drives the side panel 12 to swing to a state inclined inward relative to the main panel 11, the two cross-sections between the ends can clamp the connecting portion 24, thereby achieving the fixation of the second cloth body 22 in the wiping cloth 2, and the first cloth body 21 in the wiping cloth 2 is fixed to the main panel 11 by the Velcro 3, so that when the cleaning device is moved, the wiping cloth 2 is kept moving with the main frame plate 1, ensuring that the wiping cloth 2 and the escalator handrail 5 have sufficient relative friction, and the more stubborn stains on the escalator handrail 5 are wiped off, thereby improving the cleaning effect.

[0037] In addition, when the side panels 12 press the two sides of the second cloth body 22 against the side surfaces of the escalator handrail 5, the bottom ends thereof can extend to the bottom of the escalator handrail 5, that is, the distance between the bottom ends of the two side panels 12 is smaller than the width of the floating handrail 5, thereby forming a vertical limit for the cleaning device, making it unable to move freely up and down, thereby maintaining the main body panel 11 to press the middle part of the second cloth body 22, so that it can be stably attached to the upper surface of the escalator handrail 5, and can be well cleaned during movement.

[0038] After the wiping cloth 2 has been used for a period of time, stains adhere to the wiping cloth 2. One of the side panels 12 is manually pulled to overcome the elastic force of the torsion spring 4, so that the two side panels 12 are opened, and the distance between the bottom ends is increased, and the wiping cloth 2 can be removed from the escalator handrail 5. Further, the two side panels 12 are manually pulled to open the gap between the cut surfaces, the connecting portion 24 of the second cloth body 22 is removed, and the Velcro 3 of the first cloth body 21 is pulled open, so that the wiping cloth 2 can be removed from the main frame plate 1 for replacement and cleaning.

[0039] The moving armrest 5 can be wiped by only fixing the cleaning device, and the cleaning device keeps a stable position. The side plate 12 also keeps stable under the elastic force of the torsion spring 4, and the second cloth body 22 is kept clamped and fixed.

[0040] In the above-described exemplary embodiment, the side plates 12 on both sides of the main body frame plate 1 in the manual cleaning device for the escalator handrail 5 are hinged. Driven by the torsion spring 4, it can not only adhere to the side of the handrail 5, but also clamp the inner part of the wiping cloth 2 at the hinge, fixing the wiping cloth 2 to prevent it from moving relative to the main body frame plate 1 during the wiping process. There are no protruding structures on the inner surface of the main body frame plate 1, which can completely press the wiping cloth 2 on the surface of the escalator handrail 5, improving the cleaning effect. The overall structure is simple and the cost is low. When manually used by the cleaner, it will not obstruct the passengers from walking or getting on and off the escalator, solving the problem that the current manual wiping tool has an unsatisfactory cleaning effect due to the fixed wiping cloth 2 not being able to fit completely.

[0041] In some embodiments, the first cloth body 21 has a horizontally arranged incision 23 that extends to one end of the first cloth body 21, and both sides of the port of the incision 23 are connected by a magic tape 3.

[0042] Disconnecting the connection between both sides of the port of the incision 23 by separating the magic tape 3 can open the end of the wiping cloth 2, making it easier to operate when installing the wiping cloth 2 onto the main body frame plate 1 or removing it from the main body frame plate 1.

[0043] In some embodiments, a handle 6 is vertically installed on the outer surface of the main body plate 11, and the handle 6 extends through the incision 23. Since the wiping cloth 2 is wetted for wiping, directly holding the cleaning device to move it easily gets the hands dirty. Holding the handle 6 can achieve pushing and pulling of the cleaning device, avoiding hand contact with the wiping cloth 2. The handle 6 extends through the incision 23 of the wiping cloth 2, eliminating the need to set a penetrating structure on the wiping cloth 2, and the incision 23 of the wiping cloth 2 enables its installation and disassembly not to be hindered by the handle 6.

[0044] In some embodiments, a knob 7 is installed on the handle 6. When the escalator stops, the handrail 5 is fixed, and the cleaner needs to push and pull the cleaning device to make it move along the handrail 5 for wiping. The cleaner can hold the knob 7 and push and pull the handle 6. During the pushing and pulling process, the knob 7 rotates, thus adapting to the change in the angle between the cleaner's arm and the escalator handrail 5, making the operation of moving the cleaning device more convenient and handy.

[0045] In some embodiments, limit protrusions 15 are installed on the inner surfaces of the side plates 12. The limit protrusions 15 extend below the escalator handrail 5 and press the wiping cloth 2 against the lower surface of the escalator handrail 5.

[0046] Since the handrail 5 needs to move on the side railing 8 of the escalator, the top end of the side railing 8 is T-shaped, and the middle part at the bottom end of the escalator is open and wrapped around the top end of the side railing 8. The limiting protrusion 15 further pushes the end of the second cloth body 22 inward and upward, making it stick to the bottom surface of the handrail 5, further improving the coverage of the wiping cloth 2 on the handrail 5, and cleaning the handrail 5 of the floating body comprehensively and without dead angles, further enhancing the cleaning effect on the handrail 5.

[0047] In addition, the limiting protrusion 15 can further reduce the distance between the bottom ends of the two side plates 12, increasing the difficulty for the cleaning device to disengage from the handrail 5 from bottom to top, so that it can more stably wrap around the handrail 5 to clean it.

[0048] In some embodiments, the limiting protrusion 15 is a sponge block. Since the sponge block has elasticity, when the second cloth body 22 is attached to the lower side surface of the handrail 5, the sponge block is in a flattened state, and it presses the second cloth body 22 more tightly against the lower side surface of the handrail 5 through its elasticity. In addition, since the wiping cloth 2 needs to be wetted for wiping, under the action of gravity, the water on the wiping cloth 2 will gather downward, and the sponge block can absorb the gathered water through its water absorption property, preventing the water from dripping from the wiping cloth 2 onto the ground or the escalator, and preventing stains or slipping of personnel caused thereby.

[0049] In some embodiments, the inner surface of the limiting protrusion 15 is arc-shaped. Through the arc surface, when directly pulling the cleaning device upward, the handrail 5 can be guided to push the side plate 12 outward, facilitating the removal of the cleaning device from the handrail 5.

[0050] In some embodiments, the wiping cloth 2 includes a rubber anti-slip layer 2A and a cotton water absorption layer 2B from the inside to the outside. The inner rubber anti-slip layer 2A can adhere more firmly to the main body skeleton plate 1, generating a large frictional force to prevent the wiping cloth 2 from moving, and improving its stability after installation. In addition, the rubber anti-slip layer 2A can block water from entering the inside, avoiding water corrosion of the torsion spring 4 and improving its service life.

[0051] Finally, it should be noted that: the various embodiments in this specification are described in a progressive manner, and the key points of each embodiment are the differences from other embodiments. For the same and similar parts between the various embodiments, reference can be made to each other.

[0052] The above embodiments are only used to illustrate the technical solutions of the present invention and not to limit them; although the present invention has been described in detail with reference to the preferred embodiments, those of ordinary skill in the art should understand that: still modifications can be made to the specific implementation manners of the present invention or equivalent replacements can be made to some technical features; without departing from the spirit of the technical solutions of the present invention, they should all be covered within the scope of the technical solutions claimed by the present invention.
