Detailed Description

The following detailed description of the preferred embodiments of the present invention, taken in conjunction with the accompanying drawings, will make the advantages and features of the utility model easier to understand by those skilled in the art, and thus will clearly and clearly define the scope of the utility model.

As shown in fig. 1 to 3, an adjustable handrail belt transition guiding structure according to the present invention is installed inside an escalator to guide a handrail belt of the escalator. The transitional guide structure comprises a first support post 2 and a second support post 3. The first supporting upright post 2 and the second supporting upright post 3 are both fixed on the truss upper chord 1 through bolts. Wherein, the first supporting upright post 2 and the second supporting upright post 3 are both made of section bars. In this embodiment, the first support column 2 is arranged in the vertical direction, and the extension member 21 is installed on the first support column 2 by welding. The extension 21 extends in a horizontal direction, and a kidney-shaped hole 22 extending in a first direction is formed in the extension 21. The first direction in this embodiment is the left-right direction. The kidney-shaped hole 22 is arranged vertically through the extension 21. A transition guide assembly is arranged between the first supporting upright 2 and the second supporting upright 3. The transition guide assembly comprises a pinch roller assembly and an adjusting assembly;

wherein, this pinch roller subassembly includes fly leaf 4, pinch roller 41 and connecting piece 61. The movable plate 4 is of a circular arc-shaped structure, the first end of the movable plate 4 is connected with the second support column 3 through a bolt assembly 5, and the pressing wheels 41 are arranged on the movable plate 4 in an array manner along the second direction and rotate around the central axis of each pressing wheel. In this embodiment, the number of the pressing wheels 41 is 3, and the second direction is along a circular arc line in the vertical plane. The arc line is of a downward concave structure. In this embodiment, a rotating shaft is installed on the movable plate 4 corresponding to each pressing wheel 41, the rotating shaft is fixed on the movable plate 4, and the pressing wheels 41 are rotatably installed on the rotating shaft through bearings, so that the pressing wheels 41 can rotate around their own central axes. The puck 41 in this embodiment is a conventional component of the prior art and is preferably made of plastic.

In this embodiment, the bolt assembly 5 is a conventional component in the art, including a bolt, a lock nut, and a washer, and is used in a manner also conventional in the art.

Wherein, this adjusting part is installed between fly leaf 4 and first support post 2, and the adjusting part includes connecting piece 61, screw rod 6, adjusting nut 62. The connecting member 61 is an L-shaped angle member, which is connected to the second end of the movable plate 4 by the bolt assembly 5. The first end of the screw rod 6 is fixedly connected with the connecting piece 61, and the second end of the screw rod passes through the kidney-shaped hole 22. Specifically, a first end of the screw 6 passes through the connecting member 61, and nuts are threadedly connected to the screw 6 at both sides of the connecting member 61, so that the end of the screw 6 is locked to the connecting member 61.
