[0002] Traditional elevator guide shoes rely on sliding friction with the elevator guide rails mounted on the shaft wall. As the elevator ages, the guide rail surface becomes uneven, increasing friction and noise during relative sliding with the guide shoes, resulting in poor overall performance. Therefore, this invention proposes a T-shaped elevator guide rail. Utility Model Content

Front mounting plates are respectively provided on the left and right sides of the guide rail body. The guide rail body includes two side guide plates arranged symmetrically on the left and right sides and a front guide plate connecting the two side guide plates. A needle roller positioning rail is provided in the guide rail body for insertion from back to front. The needle roller positioning rail extends along the length direction of the guide rail body. Rear mounting plates that are close to the front mounting plates are respectively provided on the left and right sides of the needle roller positioning rail. A plurality of needle roller receiving grooves are provided on the left and right sides of the needle roller positioning rail at intervals along the length direction. The needle roller receiving grooves are arranged in a front-back extension manner. A needle roller that rotates relative to the needle roller is embedded in each of the needle roller receiving grooves. The side guide plates are provided with needle roller holes that match the needle roller receiving grooves and allow the needle rollers to extend out.

[0015] To enable those skilled in the art to better understand the technical solution of this utility model, the preferred embodiments of this utility model are described below in conjunction with specific examples. However, it should be understood that these descriptions are only for further illustrating the features and advantages of this utility model, and not for limiting the patent claims of this utility model. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without inventive effort are within the scope of protection of this utility model.

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

[0017] Example 1

[0018] See Figures 1 to 3As shown, this embodiment involves a T-shaped elevator guide rail, including a guide rail body 100 that extends vertically and has a U-shaped cross-section. Front mounting plates 101 are provided on the left and right sides of the guide rail body 100. The guide rail body 100 includes two side guide plates 102 arranged symmetrically, and a front guide plate 103 connecting the two side guide plates. A needle roller positioning rail 200 is provided inside the guide rail body 100, which is inserted from back to front. The needle roller positioning rail 200 extends along the length of the guide rail body 100. Rear mounting plates 201, which are tightly attached to the front mounting plates, are provided on the left and right sides of the needle roller positioning rail 200. Several needle roller receiving grooves 202, equidistantly arranged along the length, are provided on the left and right sides of the needle roller positioning rail 200. The needle roller receiving grooves 202 extend back and forth, and each needle roller 300 is embedded in a relatively rotating needle roller. A needle roller hole 103 is provided on the side guide plate 102 to match the needle roller receiving groove and allow the needle roller portion to extend out.

[0019] Furthermore, the needle roller positioning rail 200 includes a positioning rail body 2001 and a front support plate 2002. The needle roller receiving groove 202 is disposed between the positioning rail body 2001 and the front support plate 2002. The needle roller receiving groove 202 is disposed on the positioning rail body 2001. The front end of the needle roller receiving groove 202 is connected to the outside. The front end of the front support plate 2002 abuts against the front guide plate 103 and the rear end abuts against the positioning rail body 2001.

[0020] Furthermore, an elastic element 400 is provided between the front support plate 2001 and the positioning rail body 2001, and the elastic element 400 is a compression spring.

[0021] Furthermore, it also includes mounting holes 500 that penetrate the front mounting plate 101 and the rear mounting plate 201 from front to back.

[0022] In this embodiment, a plurality of needle roller receiving cavities are formed between the assembled guide rail body 100 and the needle roller positioning rail 200 in a left-right symmetrical arrangement. The main part of the needle roller receiving cavity is in the needle roller receiving groove 202, and the rest is in the needle roller hole 103 position, so that the part of the needle roller 300 that cannot be completely embedded in the needle roller receiving groove 202 is exposed, so that the side guide plate 102 that was originally in contact with the guide shoe is changed to the needle roller 300, changing the original sliding friction to rolling friction, thereby reducing the friction force.

[0023] The needle roller positioning rail 200 includes a positioning rail body 2001 and a front support plate 2002. The split structure makes assembly easier.

[0024] The mounting holes 500 serve two purposes: firstly, to fix the guide rail body 100 and the needle roller positioning rail 200 together; and secondly, to fix the entire elevator guide rail to the shaft wall.

[0025] Example 2

[0026] See Figures 1 to 3 As shown, the T-shaped elevator guide rail involved in this embodiment is further configured, based on embodiment 1, with the front support plate 2002 and the positioning rail body 2001 respectively provided with positioning grooves 203 for the elastic element to be partially embedded.

[0027] In this embodiment, the positioning groove 203 is used to position and install the elastic element 400.

[0028] The T-shaped elevator guide rail involved in this utility model has its original sliding friction between the elevator guide rail and the guide shoe changed to the improved rolling friction, which reduces friction, lowers noise, improves overall function, and is highly practical.
