The rotating rod comprises a handle and a screw. The screw is vertically connected to the middle of the handle and is threadedly connected to the threaded through hole in the top plane.

[0006] The opposite ends of the two half bottom plates are integrally connected with support pads extending upward.

[0007] The upward extension height of the support pad is 3 / 10 of the height of the inner cavity of the fixing sleeve.

[0008] The distance between the two half bottom sealing plates of the bottom of the fixed sleeve is equivalent to the outer diameter of the connection point of the escalator step wheel shaft.

[0009] The beneficial effects of the utility model are as follows: the utility model has a simple structure and a reasonable design, the escalator step wheel can be quickly disassembled, the operation is simple and fast, time and labor are saved, and work efficiency is improved.

[0015] The following is a detailed description of the embodiments of the present invention with reference to the accompanying drawings. DETAILED DESCRIPTION

[0016] The present invention will be further described below with reference to the accompanying drawings and embodiments:

[0017] like Figure 1-Figure 3 As shown, a quick disassembly tool for an escalator step wheel includes a fixing sleeve 1 and a rotating rod 2. The fixing sleeve 1 is in an inverted "U" shape with a semi-closed bottom. The top of the fixing sleeve 1 is a top plane 11, and a threaded through hole 14 is opened in the middle of the top plane 11. The bottoms of both sides of the fixing sleeve 1 are semi-closed bottom plates 12. The rotating rod 2 includes a handle 21 and a screw 22. The screw 22 is vertically connected to the middle of the handle 21, and the screw 22 is threadedly connected to the threaded through hole 14 of the top plane 11.

[0018] The opposite ends of the two semi-sealed bottom plates 12 are integrally connected with support blocks 13 extending upward. After the step wheel 3 is sleeved in the fixed sleeve 1 , the support blocks 13 are supported on the bottom of the step wheel 3 .

[0019] The upward extension height of the support pad 13 is 3 / 10 of the inner cavity height of the fixing sleeve 1 .

[0020] The distance between the two bottom sealing plates 12 of the fixing sleeve 1 is equivalent to the outer diameter of the connection between the escalator step wheel axle 4, ensuring that the connection between the wheel axle 4 and the step wheel 3 is extended from the bottom of the fixing sleeve 1 when the step wheel 3 is sleeved in the fixing sleeve 1.

[0021] When applied, such as Figure 4 As shown, put the fixed sleeve 1 on the step wheel 3, turn the handle 21 of the rotary rod 2, so that the screw 22 is screwed into the fixed sleeve 1 to press the step wheel shaft 4, and pull the step wheel 3 upward a little bit to make the step wheel 3 withdraw from the step wheel shaft 4.

[0022] In the description of the present invention, it should be understood that the terms "center", "longitudinal", "lateral", "length", "width", "thickness", "up", "down", "front", "back", "left", "right", "vertical", "horizontal", "top", "bottom", "inside", "outside", "clockwise", "counterclockwise", "axial", "radial", "circumferential" and the like to indicate orientations or positional relationships based on the orientations or positional relationships shown in the accompanying drawings, and are only for the convenience of describing the present invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation, and therefore should not be understood as a limitation to the present invention.

[0023] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of the technical features being referred to. Thus, a feature specified as "first" or "second" may explicitly or implicitly include at least one such feature. In the description of this utility model, "plurality" means at least two, such as two, three, etc., unless otherwise specifically defined.

[0024] In this utility model, unless otherwise specified or limited, the terms "installed," "connected," "connect," "fixed," etc. should be understood in a broad sense. For example, they can refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; internal communication between two elements or interaction between two elements, unless otherwise specified. For those skilled in the art, the specific meanings of the above terms in this utility model can be understood according to specific circumstances.

[0025] The above is an exemplary description of the present invention in conjunction with the accompanying drawings. It is obvious that the specific implementation of the present invention is not limited to the above-mentioned method. As long as various improvements are made using the method concept and technical solution of the present invention, or they are directly applied to other occasions without improvement, they are all within the scope of protection of the present invention.
