DETAILED DESCRIPTION

[0028] The following is combined with Figure 1 -Attached Figure 3 , further details of this application are given. Example

[0029] A long-stroke linear motor module with built-in drag chain, refer to Figure 1 and Figure 2 The chassis 1 serves as the basic support, and a sliding mechanism 2 is installed inside it. The core of the sliding mechanism 2 is the sliding plate 20, and limit plates 21 are provided on both sides of it to slide with the inner surface of the chassis 1 to ensure sliding stability. A plurality of electric sliders 27 are installed at the bottom of the sliding plate 20. These sliders move on the electric slide rails 26 fixed in the chassis 1 to achieve long-stroke linear motion. In addition, the sliding plate 20 is also provided with a positioning block 23, which cooperates with the auxiliary drag chain 25 inside the chassis 1 to assist and guide the movement of the sliding plate 20. The limit grooves 22 opened on both sides of the chassis 1 are closely fitted with the limit plates 21, further enhancing the guiding property of the sliding mechanism 2.

[0030] Reference Figure 2 The limiting grooves 22 on both sides of the base frame 1 fit tightly with the limiting plates 21 on both sides of the sliding plate 20, effectively limiting the lateral deviation of the sliding plate 20 during movement. Multiple electric sliders 27 are distributed in a rectangular array at the lower end of the sliding plate 20, which not only disperses the load-bearing weight but also provides a uniform and stable guiding force. The sliding fit design of the positioning plate 24 and the positioning block 23 provides an additional positioning reference for the movement of the sliding plate 20 in the base frame 1.

[0031] Reference Figure 3 The mounting mechanism 3 is located above the sliding mechanism 2 and is mainly composed of a mounting frame 30, a plurality of mounting cylinders 34 are fixed at the lower end thereof, each mounting cylinder 34 is connected to a mounting screw 32 by a threaded connection, a knob 31 is provided at the upper end of the screw for easy operation, and a mounting rod 33 is connected to the lower end thereof, and an anti-slip groove 37 is provided on the outer surface of the knob 31 to improve the holding stability, and movable grooves 35 are distributed on the outer surface of the mounting cylinder 34, and movable beads 36 are arranged inside for movement. These movable beads 36 are in sliding contact with the outer surface of the mounting rod 33 and the mounting screw 32, so that the movement of the movable beads 36 can be adjusted by the mounting rod 33 and the mounting screw 32, and the mounting frame 30 is limited at the lower end of the sliding plate 20.

[0032] Reference Figure 3 The anti-slip groove 37 design on the outer surface of the knob 31 effectively increases the hand friction during operation. The design of the movable groove 35 distributed in an annular manner on the outer surface of the mounting cylinder 34 allows the movable bead 36 to be effectively limited. The outer surfaces of the mounting rod 33 and the mounting screw 32 slide in contact with the movable bead 36, so that the movement of the movable bead 36 can be adjusted by the mounting rod 33 and the mounting screw 32.

[0033] The implementation principle of the embodiment of the present application is as follows: the sliding mechanism 2 can realize long-stroke linear motion in the base frame 1 through the sliding plate 20 at its core. The limit plates 21 on both sides of the sliding plate 20 are tightly fitted with the limit grooves 22 on both sides of the base frame 1 to ensure stability and directionality during the sliding process. A plurality of electric sliders 27 installed at the bottom of the sliding plate 20 slide on the electric slide rails 26 fixed in the base frame 1. These sliders are distributed in a rectangular array, which not only disperses the load-bearing weight but also provides a uniform and stable driving force. At the same time, the positioning blocks 23 on the sliding plate 20 cooperate with the auxiliary drag chains 25 in the base frame 1 to further assist and guide the movement of the sliding plate 20. The entire sliding mechanism 2 realizes efficient and stable long-stroke linear motion through the precise cooperation of the electric sliders 27 and the electric slide rails 26.

[0034] Through the mounting mechanism 3, each mounting cylinder 34 is connected to the mounting screw 32 by a threaded connection, and the knob 31 at the upper end of the screw is convenient for the operator to install and adjust. When the knob 31 is rotated, the mounting screw 32 drives the mounting rod 33 to move up and down, thereby adjusting the limit of the mounting frame 30 on the sliding plate 20. The movable groove 35 on the outer surface of the mounting cylinder 34 is provided with movable beads 36. These movable beads 36 are in sliding contact with the outer surface of the mounting rod 33 and the mounting screw 32, so that the movement of the movable beads 36 can be ejected through the mounting rod 33 and the mounting screw 32, and the mounting frame 30 is fixed to the sliding plate 20. In addition, the anti-slip groove 37 design on the outer surface of the knob 31 improves the hand friction during operation, ensuring the accuracy and stability of the adjustment.
