Its technical solution discloses "escalator guide rail system, including guide rails located on both sides of the steps, escalator step sprockets are disposed on the guide rails, and a limiting part is provided protruding on the surface of the guide rails, the limiting part blocking the outside of the step sprockets".

[0003] Therefore, the above utility model patents have disclosed one technical solution for escalator guide rail systems. However, the technical solutions disclosed in these utility model patents focus on effectively ensuring that the steps and skirt panels maintain a minimum gap, greatly reducing the risk of foreign objects getting stuck between the skirt panels and steps. They do not further address issues such as the spatial constraints on the transmission chain structure and require further improvement. Utility Model Content

[0004] This utility model addresses the shortcomings of the existing technology by providing an escalator guide rail system.

[0005] This utility model adopts the following technical solution: an escalator guide rail system, including a support mechanism and a transmission chain structure, wherein the transmission chain structure is located on one side of the support mechanism, wherein:

[0006] The support mechanism includes two ring structures, with the conduction chain structure externally connected to one of the ring structures;

[0007] The conduction chain structure includes multiple conduction chain units connected end to end. Each conduction chain unit includes a first conduction chain and a second conduction chain. The first conduction chain and the second conduction chain are alternately distributed and rotatably connected.

[0008] The first transmission chain has a first rotating part and a second rotating part at its two ends, and the second transmission chain has a first rotating part and a second rotating part at its two ends, and the second rotating part of the first transmission chain is rotatably connected to the first rotating part of the second transmission chain.

[0010] As a preferred technical solution of the above technical solutions, the top cover includes a top cover body and top cover protrusions disposed on both sides of the top cover body. The top cover protrusions are integrally formed with the top cover body, and the transmission chain structure is internally connected to one of the top cover protrusions.

Detailed Implementation

[0025] This utility model discloses an escalator guide rail system. The following description, in conjunction with a preferred embodiment (Embodiment 1), refers to the accompanying drawings. Figures 1 to 10 The specific embodiments of this utility model will be further described below.

[0026] See attached diagram. Figures 1 to 10 , Figures 1 to 3 The escalator guide rail system is shown from different perspectives. Figure 4 and Figure 5 Conductor chain units from different perspectives are shown. Figure 6 and Figure 7 The first conduction chain is shown from different perspectives.

[0027] Example 1.

[0028] Preferably, the escalator guide rail system includes a support mechanism 100 and a transmission chain structure 200, wherein the transmission chain structure 200 is located on one side of the support mechanism 100, wherein:

[0029] The support mechanism 100 includes two ring structures 120, and the conduction chain structure 200 is externally connected to one of the ring structures 120.

[0030] The conduction chain structure 200 includes multiple conduction chain units 300 connected end to end. Each conduction chain unit 300 includes a first conduction chain 400 and a second conduction chain 500. The first conduction chain 400 and the second conduction chain 500 are alternately distributed and rotatably connected.

[0031] The first transmission chain 400 has a first rotating part 410 and a second rotating part 420 at its two ends, and the second transmission chain 500 has a first rotating part 510 and a second rotating part 520 at its two ends. The second rotating part 420 is rotatably connected to the first rotating part 510 of the second transmission chain. The first rotating part 410 of the first transmission chain is further connected to the first rotating mechanism (not shown in the figure) of the escalator step of the escalator 600, and the second rotating part 520 of the second transmission chain is further connected to the second rotating mechanism (not shown in the figure) of the escalator step of the escalator 600. This is so that when the transmission chain structure 200 reciprocates along the ring structure 120, it drives the first rotating mechanism and the second rotating mechanism of the escalator step to move synchronously, ultimately causing the escalator step to reciprocate.

[0032] The support mechanism 100 also includes a top cover 110, with two annular structures 120 disposed on both sides of the top cover 110, and the two annular structures 120 being integrally formed with the top cover 110.

[0033] The top cover 110 includes a top cover body 112 and top cover protrusions 111 respectively disposed on both sides of the top cover body 112. The top cover protrusions 111 are integrally formed with the top cover body 112, and the transmission chain structure 200 is connected to one of the top cover protrusions 111 to help constrain the transmission chain structure 200 at a specified position (inside the top cover protrusion 111).

[0034] The first transmission chain second rotating part 420 is provided with a first transmission chain contraction part 422 and a first transmission chain first protrusion part 421 and a first transmission chain second protrusion part 423 respectively disposed on both sides of the first transmission chain contraction part 422. The first transmission chain first protrusion part 421 and the first transmission chain second protrusion part 423 are integrally formed with the first transmission chain contraction part 422.

[0035] The first rotating part 510 of the second transmission chain has a first positioning hole 511 of the second transmission chain, and the first contraction part 422 of the first transmission chain is connected to the first positioning hole 511 of the second transmission chain; this facilitates the rotatable connection between the first contraction part 422 of the first transmission chain and the first rotating part 510 of the second transmission chain.

[0036] The transmission chain structure 200 is driven by the drive mechanism (not shown in the figure) of the escalator 600 so that when the transmission chain structure 200 reciprocates along the ring structure 120, it drives the first rotating mechanism and the second rotating mechanism of the escalator steps to move synchronously, ultimately causing the escalator steps to reciprocate.

[0037] Example 2.

[0038] The difference between the technical solution of Embodiment 2 and the technical solution of Embodiment 1 is that Embodiment 1 has one and only one conduction chain structure 200, and the conduction chain structure 200 is located on one side of the support mechanism 100; in contrast, Embodiment 2 has one and only two conduction chain structures 200, and the two conduction chain structures 200 are respectively arranged on both sides of the support mechanism 100. The specific structure of the conduction chain structure 200 in Embodiment 2 is the same as the specific structure of the conduction chain structure 200 in Embodiment 1.

[0039] It is worth mentioning that the technical features such as the drive mechanism of the escalator 600 involved in this utility model patent application should be regarded as prior art. The specific structure, working principle and possible control method and spatial arrangement of these technical features can be adopted by conventional choices in the field and should not be regarded as the inventive point of this utility model patent. This utility model patent will not elaborate further.

[0040] For those skilled in the art, modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
