DETAILED DESCRIPTION

[0017] The present invention will be further described below in conjunction with the accompanying drawings and specific implementations. It should be understood that the following specific implementations are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0018] like Figure 1 and Figure 2As shown, a guide rail structure of a pull rod lifting platform includes a rotary motor; the rotary motor 6 is invertedly installed in the central installation groove of the support base 7, a track plate 5 is installed at the top center of the support base 7, and four groups of slide rails 13 are evenly distributed on the top end surface of the track plate 5. A slider carrier 4 is slidably installed on the slide rail 13, and the slider carrier 4 is wound and connected with a spiral sleeve 11 through a transmission steel cable, and the spiral sleeve 11 is connected to the rotary motor 6 through a rotating shaft 15. Four groups of connecting ear pieces 9 extend on both sides of the synchronous sleeve 2, and a driving arm 3 is rotatably installed on the connecting ear piece 9, and the root of the driving arm 3 is connected to the slider carrier 4 through a change-of-direction joint. Among them, the support base 7 is used as an installation and load-bearing component. In order to effectively utilize the installation space, a rotating motor 6 is installed in the installation groove at the bottom of the support base 7. The rotating motor 6 drives the spiral sleeve 11. The spiral sleeve 11 rotates to wind the transmission steel cable, and the steel cable drives the slider carrier 4 to perform the contraction and translation process. During the contraction process, the slider carrier 4 will synchronously drive the arm 3 to move together, and at the same time push the synchronous sleeve 2 and the top platform layer 1 to lift.

[0019] like Figure 1 and Figure 2 As shown, the spiral sleeve 11 and the slide rail 13 are countersunk installation structures. The countersunk installation structures of the spiral sleeve 11 and the slide rail 13 can prevent the top horizontal installation structure from colliding with the spiral sleeve 11 and the slide rail 13.

[0020] like Figure 1 and Figure 2 As shown, a guide rod 8 is vertically installed in the center of the track plate 5 along the direction of the spiral sleeve 11, and a synchronous sleeve 2 is movably installed on the rod body of the guide rod 8 through a guide groove 12, and the top end of the synchronous sleeve 2 is synchronously connected with the top platform 1. The guide rod 8 serves as a balancing center rod, which can concentrate the force of the driving arm 3 pushing toward the center to the vertical upward direction to complete the pushing process.

[0021] like Figure 1 and Figure 2 As shown, the track plate 5 is fixedly connected to the support base 7 along the edge position through the fixing bolt 14. Among them, the fixing bolt 14 can cooperate with the track plate 5 to be fixedly connected to the support base 7 to complete the disassembly and installation process, and adapt to the later maintenance and repair.

[0022] It should be noted that the above content only illustrates the technical idea of ​​the utility model and cannot be used to limit the protection scope of the utility model. For ordinary technicians in this technical field, several improvements and modifications can be made without departing from the principle of the utility model. These improvements and modifications all fall within the protection scope of the claims of the utility model.
