The handrail frame includes stainless steel exterior parts, handrail frame aluminum profiles, and handrail guide brackets.

[0003] During installation, the workers first peeled off the protective film of the tape and applied it to the wall panel, securing the handrail frame aluminum profile to the tape. Next, holes were drilled on the upper part of the stainless steel exterior component and the two bent edges of the handrail guide rail bracket. The stainless steel exterior component, handrail guide rail bracket, and LED strip mounting bracket were then installed on the handrail frame aluminum profile. The handrail guide rail was installed on the stainless steel exterior component and the handrail guide rail bracket. Plastic seals were used to protect the bottom of the stainless steel exterior component to prevent scratches to passengers' hands. Subsequently, the LED strip fixing clips were installed on the lamp holder mounting bracket, securing the LED strip in the clips. The lampshade was then installed on the LED strip mounting bracket using fasteners. Finally, roller belts were installed at the upper and lower ends and the R-section of the handrail device, and these roller belts were installed inside the handrail guide rail cavity.

[0072] In the present embodiment, the roller 1150 is arranged in the turning portion 1143 of the handrail guide rail 1140 and rotatably connected with the turning portion 1143, the outer periphery of the roller 1150 is used to abut against the bottom wall of the groove 1210 on the inner side of the handrail belt 1200, so that the part of the handrail belt 1200 on the turning portion 1143 is matched with the roller 1150, and when the handrail belt 1200 slides relative to the turning portion 1143, the roller 1150 rotates about its central axis relative to the turning portion 1143.

[0073] Please refer to Figures 5 to 7 In some embodiments, the handrail guide rail 1140 comprises a curved portion 1144 arranged on the side of the horizontal portion 1142 away from the inclined portion 1141 and bent away from the corresponding horizontal portion 1142, the handrail device 1100 comprises a plurality of rollers 1160 and a plurality of guide pieces 1170, the plurality of rollers 1160 and the plurality of guide pieces 1170 are arranged along the bending direction of the curved portion 1144 and arranged in the curved portion 1144, at least one roller 1160 is arranged between any two adjacent guide pieces 1170, the side of the guide piece 1170 away from the mounting piece 1111-1 is a lug 1171, the lug 1171 is located outside the curved portion 1144 and is used to limit in the groove 1210 on the inner side of the handrail belt 1200, the roller 1160 is rotatably connected with the curved portion 1144 and can rotate about its central axis relative to the curved portion 1144, the central axis of the roller 1160 is parallel to the second direction, and the outer periphery of the roller 1160 is used to abut against the bottom wall of the groove 1210 on the inner side of the handrail belt 1200.

[0074] In this embodiment, the plurality of guide members 1170 are arranged along the bending direction of the bending portion 1144 and located in the bending portion 1144. The side of the guide member 1170 away from the mounting member 1111-1 is a lug 1171. The lug 1171 is located outside the bending portion 1144 and is used to limit the lug 1171 in the groove 1210 on the inner side of the handrail belt 1200. The lug 1171 is used to limit the handrail belt 1200 from being separated from the bending portion 1144 of the handrail guide rail 1140, so that the handrail belt 1200 bends and advances according to the bending direction of the bending portion 1144. The roller 1160 is arranged in the bending portion 1144 and rotationally connected with the bending portion 1144. The outer circumferential surface of the roller 1160 is used to abut against the bottom wall of the groove 1210 on the inner side of the handrail belt 1200. The part of the handrail belt 1200 in the bending portion 1144 is matched with the roller 1160. When the handrail belt 1200 slides relative to the bending portion 1144, the roller 1160 rotates relative to the bending portion 1144 about the central axis of the roller 1160, thereby reducing the movement resistance of the handrail belt 1200.

[0075] In some embodiments, the distance between the lug 1171 and the mounting member 1111-1 in the first direction is adjustable. In other words, in the actual installation process, each guide member 1170 can be adjusted individually, so that the distance between each lug 1171 and the mounting member 1111-1 in the first direction meets the requirements.

[0076] Specifically, as shown in Figure 7 , assuming that the part of the guide member 1170 located in the bending portion 1144 is a fixed portion 1172, the lug 1171 can be fixed on the fixed portion 1172 by using a connecting member such as a screw or a bolt. The hanging direction of the connecting member is the direction in which the lug 1171 protrudes out of the bending portion 1144. Therefore, by adjusting the depth at which the connecting member hangs into the fixed portion 1172, the distance between the lug 1171 and the mounting member 1111-1 in the first direction is adjusted.

[0077] In some embodiments, the lug 1171 has a circular pie structure, and the end face of the lug 1171 away from the mounting member 1111-1 is an end face of the circular pie structure. The end face of the lug 1171 abuts against the bottom wall of the groove 1210 on the inner side of the handrail belt 1200.

[0078] In some embodiments, the plane in which the rotation axis of each roller 1160 is located is a reference arc plane. The minimum distance between the end face of the lug 1171 away from the mounting member 1111-1 and the reference arc plane is consistent with the radius of the roller 1160.

[0079] Please refer to Figure 1 , Figure 1A structure schematic diagram of an escalator in an embodiment of the present application is shown. An escalator 1000 provided by an embodiment of the present application includes the aforementioned handrail device 1100, and a handrail belt 1200 and a guard plate 1300.

In the handrail device 1100 of the escalator 1000 of the present embodiment, the handrail frame 1111 only includes the mounting member 1111-1, the support member 1111-2 and the reinforcing member 1111-3, and the number of components of the handrail frame 1111 is small. The support member 1111-2 is located on the side of the mounting member 1111-1 along the first direction and is connected to the end of the mounting member 1111-1 along the second direction. The support member 1111-2 extends along the first direction, and the first direction intersects the second direction. The reinforcing member 1111-3 is located on the side of the mounting member 1111-3 close to the support member 1111-2. One end of the reinforcing member 1111-3 is connected to the mounting member 1111-1, and the other end is connected to the support member 1111-2. The structure of the handrail frame 1111 is simple, and the staff can use the integrated forming technology to manufacture the handrail frame 1111, so the manufacturing cost of the handrail frame 1111 is low. The mounting slot 1112 is arranged on the side of the mounting member 1111-1 away from the support member 1111-2 and is arranged at intervals on the side of the support member 1111-2 along the second direction. The mounting slot 1112 is provided with the fastener 1113. One end of the fastener 1113 is clamped to the mounting slot 1112, and the other end extends out of the mounting slot 1112. The fastener 1113 is arranged on the handrail frame 1111. The staff can directly connect the handrail guide rail 1140 to be installed to the handrail frame 1111 by means of the fastener 1113 on the handrail frame 1111, thereby omitting the conventional process of drilling holes in the handrail frame 1111 and assembling fastening screws. The installation process of the handrail frame 1111 is simple. In summary, the escalator 1000 in the present embodiment reduces the components of the handrail frame 1111, simplifies the connection mode of each part of the handrail frame 1111, arranges the fastener 1113 on the handrail frame 1111, reduces the number of components of the escalator 1000, makes the structure simpler, simplifies the installation process, and reduces the installation difficulty.
