[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] Embodiment 1

[0026] like Figure 1 — Figure 2 As shown, a handrail assembly structure of the utility model includes a guide rail 100, a wheel assembly 200, a heating wire 300 and a clamping plate 400.

[0027] The wheel assembly 200 is arranged in the guide rail 100, and a handrail 230 is slidably connected to the guide rail 100. A heating wire 300 is passed through the inner bottom end of the wheel assembly 200. When the handrail 230 slides relative to the guide rail 100, the wheel assembly 200 is rollingly connected to the handrail 230 to support and guide the handrail 230. In this process, the heating wire 300 generates heat, which heats the handrail 230 so that people will not feel cold when touching the handrail 230 under low temperature conditions, thereby improving people's comfort when riding the escalator; a plurality of pairs of splints 400 are also provided at the inner bottom end of the wheel assembly 200 for limiting the misalignment and movement of the heating wire 300. By setting a plurality of pairs of splints 400, the heating wire 300 can be prevented from being misaligned and moved in the wheel assembly 200 during use, and direct contact between the heating wire 300 and the handrail 230 can be avoided.

[0028] Furthermore, in the present invention, the heating wire 300 is located in the guide rail 100 , and the top of the guide rail 100 is covered by the handrail 230 , so that rainwater can be prevented from intruding into the guide rail 100 and also from affecting the heating wire 300 .

[0029] The two clamps 400 of the same pair are respectively located on both sides of the heating wire 300, and there is a squeezing force between each clamp 400 and the heating wire 300. The cross-sectional shape of each clamp 400 is L-shaped. The connection method between each clamp 400 and the wheel assembly 200 can be a fixed connection or a bolt connection. The wheel assembly 200 includes a shell 210 arranged in the guide rail 100. During installation, people need to connect the clamp 400 with the inner bottom end of the shell 210. During this process, the heating wire 300 needs to be clamped between the two clamps 400, and there is a squeezing force between the heating wire 300 and the clamp 400, so that the clamp 400 can clamp the heating wire 300, thereby avoiding the heating wire 300 from being misplaced and moved during use.

[0030] A guide wheel 220 is movably installed in the shell 210, and the guide wheel 220 is rollingly connected to the handrail belt 230. An inwardly recessed annular groove 221 is provided on the surface of the guide wheel 220, and a clamping strip 231 is provided in the middle of the bottom surface of the handrail belt 230, and the clamping strip 231 is inserted into the annular groove 221. Specifically, the side wall of the annular groove 221 is inclined, and the side wall of the annular groove 221 contacts the side surface of the clamping strip 231. When the handrail belt 230 slides relative to the guide rail 100, the clamping strip 231 on the handrail belt 230 is inserted into the annular groove 221, and the guide wheel 220 is rollingly connected to the clamping strip 231, and the guide wheel 220 is movably installed in the shell 210. In this way, the handrail belt 230 can be prevented from shaking left and right relative to the guide rail 100 when sliding relative to the guide rail 100, so that the handrail belt 230 can slide stably relative to the guide rail 100.

[0031] The heating wire 300 and the handrail belt 230 are respectively located on both sides of the guide wheel 220, and parts of the splint 400 and the heating wire 300 are embedded in the annular groove 221. It can be seen that the annular groove 221 in the utility model can not only prevent the handrail belt 230 from shaking left and right relative to the guide rail 100, but also provide a holding space for the splint 400 and the heating wire 300, so that the splint 400 and the heating wire 300 can be smoothly installed in the shell 210, which reflects the rationality of the design of the armrest belt assembly structure.

[0032] A shaft 211 for mounting the guide wheel 220 is passed through the shell 210, a bearing 212 is installed between the shaft 211 and the guide wheel 220, baffles 211a are provided at both ends of the shaft 211, and the two baffles 211a are both located on the outside of the shell 210. By setting the baffles 211a, the shaft 211 can be prevented from moving relative to the shell 210, thereby ensuring that the guide wheel 220 can rotate stably around the shaft 211.

[0033] Embodiment 2

[0034] like Figure 3 — Figure 4 As shown, this embodiment is based on the first embodiment, and an anti-drop plate 410 is additionally provided.

[0035] Specifically, at least one of the splints 400 is provided with an anti-slip plate 410, and the anti-slip plate 410, the two splints 400 and the inner bottom of the shell 210 wrap the heating wire 300. Through the setting of the anti-slip plate 410, the heating wire 300 is further prevented from detaching from between the two splints 400, thereby ensuring that the heating wire 300 can work stably.

[0036] It should be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back...) are only used to explain the relative position relationship, movement status, etc. between the components under a certain specific posture (as shown in the accompanying drawings). If the specific posture changes, the directional indication will also change accordingly.

[0037] In addition, in the present invention, the descriptions of "first", "second", "one", etc. are only used for descriptive purposes and cannot be understood as indicating or implying their relative importance or implicitly indicating the number of the indicated technical features. Therefore, the features defined as "first" or "second" may explicitly or implicitly include at least one of the features. In the description of the present invention, the meaning of "plurality" is at least two, such as two, three, etc., unless otherwise clearly and specifically defined.

[0038] In the present invention, unless otherwise clearly specified and limited, the terms "connection", "fixation", etc. should be understood in a broad sense. For example, "fixation" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium, it can be the internal connection of two elements or the interaction relationship between two elements, unless otherwise clearly defined. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0039] In addition, the technical solutions between the various embodiments of the present invention can be combined with each other, but it must be based on the fact that ordinary technicians in the field can implement it. When the combination of technical solutions is contradictory or cannot be implemented, it should be deemed that such combination of technical solutions does not exist and is not within the scope of protection required by the present invention.
