[0002] Elevators are used more and more widely in people's lives and are well known to people. The elevator bridge is one of the main parts of the elevator. It relies on the guide rails for guidance when in use. The elevator guide rails are elevator components composed of steel rails and connecting plates. They are divided into car guide rails and counterweight guide rails. From the cross-sectional shape, they are divided into three types: T-shaped, L-shaped and hollow.

[0003] In the patent application with the authorization publication number CN216272569U and the authorization publication date 2022-04-12, and the name of "An Elevator Guide Rail", the fixed column and the card block are set, so that the connection between the main rails can be made after the card block is engaged, and then the fixed block is pushed into the inside of the fixed groove, so that the connection between the main rails is more firm, and the inclination of the main rails after the connection is reduced. The spring electric fixed slider can also be set to effectively fix the main rails after the connection, reduce the shaking of the fixed column and the card block in the fixed groove, and improve the use effect and installation efficiency of the overall main rail;

[0004] When the above mechanism is actually used, the connection of the elevator main rail is achieved through the vertical connection of the fixed column and the fixed groove. This connection method will affect the upper and lower main rails when the main rail is repaired and maintained, and the fixed slider connected with a spring has poor stability when used for the elevator main rail connection.

[0005] Therefore we have proposed a main elevator rail that is easy to maintain, so as to solve the above-mentioned problems. Utility Model Content

During the insertion process, the positioning block, under the cooperation of the pressure spring and the sliding column, will extend into the interior of the positioning groove opened on the side of the connecting block when the insertion is completed, so as to improve the connection effect of the two main rails. Then, the rotating rod is rotated, and the pressing block sleeved on the end of the rotating rod can be fitted to the side of the positioning block under the fitting action of the fixing plate. During the continuous rotation process, the pressing block will cause the positioning block to fit closely to the interior of the positioning groove, so as to further improve the connection stability between the guide rails.
