The screw lifting assembly 8 includes a vertically arranged screw, and a sliding nut 14 that can move vertically is provided on the outer periphery of the screw. The sliding nut 14 is fixedly connected to the lifting bracket body, and as the sliding nut 14 slides up and down along the screw, it drives the lifting bracket body to move up and down. Preferably, at least one fixing plate 2 is provided. The fixing plate 2 is fixedly connected to the fixing part of the left and right slide rails 15 through the integrally provided fixing hole 23. The outer shell of the screw lifting assembly 8 is fixedly connected to the fixing plate 2.

[0039] Specifically, the lifting bracket includes a left column 10 and a right column 4 arranged parallel to each other at the left and right ends of the fixed plate 2, and a hanging plate 12 whose ends are fixedly connected to the corresponding columns. Switch assemblies for closing bottom openings are fixedly connected to the bottom surfaces of the left column 10 and right column 4, respectively. The base plate is fixedly connected to the switch assemblies. Preferably, the hanging plate 12 has integrated hanging plate fixing holes 18 at both ends, and the middle part of the hanging plate 12 is fixedly connected to a slider nut 14. Both ends are fixedly connected to the corresponding left column 10 and right column 4 through the hanging plate fixing holes 18. The left column 10 and right column 4 each have integrated two or more slide rail fixing holes 24. The left column 10 is fixedly connected to the slide rail 15 on the same side through the slide rail fixing holes 24, and the right column 4 is fixedly connected to the slide rail 15 on the same side through the slide rail fixing holes 24. Preferably, light bulbs or light strips for illumination are provided on the left column 10 and right column 4 for use in dimly lit environments.

[0040] The switch assembly includes a left switch assembly 28 and a right switch assembly 27, which are independently and fixedly connected to the left column 10 and the right column 4, respectively, and then fixedly connected to the base plate 5. The base plate 5 is connected to the left and right columns through the left and right switch assemblies. The left switch assembly 28 includes an upper left fixing plate 281, a lower left fixing plate 283, a limit switch 275, a spring 276, a washer 277, and a limit screw 278. The right switch assembly 27 includes an upper right fixing plate 271, a lower right fixing plate 273, a limit switch 275, a spring 276, a washer 277, and a limit screw 278.

The guide posts of the upper left and lower right fixing plates pass through the lower left and right fixing plates and are limited by screws 278, so that the lower left and right fixing plates are fixedly connected to the base plate 5. The fixed plates are axially connected along the guide column. There is at least one limit switch 275 and at least three springs 276 between the upper left fixed plate 281 and the lower left fixed plate 283. There is at least one washer 277 on the guide column. There is at least one limit switch 275 and at least three springs 276 between the upper right fixed plate 271 and the lower left fixed plate 273. There is at least one washer 277 on the guide column. When the bottom plate is pressed, the lower left and right fixed plates move towards the upper left and right fixed plates. The springs between the upper left and right fixed plates and the lower left and right fixed plates are compressed synchronously. The limit switches fixed on the lower left and right fixed plates touch the upper left and right fixed plates. The limit switches are triggered and send an electrical signal to the controller. The controller controls the lifting bracket to rise or fall. When the bottom plate is released, the elastic force of the springs 276 causes the lower fixed plate and the bottom plate 5 to return to their initial positions.

[0041] The left column 10 and the right column 4 are provided with column fixing holes 25 that extend through the length direction. Fixing components such as screws or bolts pass through the fixing plates on the left and right switch assemblies and the column fixing holes 25 to fix them, thereby achieving a fixed connection between the columns and the switch assemblies.

[0042] The left column 10 and the right column 4 have the same structure, both being hollow structures. The hollow structure forms a relatively independent slide rail placement cavity for accommodating the slide rail 15 and a wire-passing cavity 26 for the connecting line 9, which will be described in detail below, to pass through. In order to reduce the difficulty of cleaning dust inside the hollow structure, a left column decorative cover 11 and a right column decorative cover 3 are respectively fastened to the upper opening of the left column 10 and the right column 4.

[0043] Furthermore, the left switch assembly 28 is integrally provided with a switch wire hole 284, and the right switch assembly 27 is integrally provided with a switch wire hole 274. One end of the connecting wire 9 is fixedly connected to the electrical protection box 1 through the wire clamping block 13, and the other end passes through the cavity of the drag chain 22 and is fixed to the hanging plate 12 of the lifting bracket body. Then it passes through the upper left decorative cover 11 of the left column 10 and the upper right decorative cover 3 of the right column 4, then through the wire passage cavity 26 of the left and right columns, and finally through the wire hole 284 of the left switch assembly and the wire hole 274 of the right switch assembly to enter the switch assembly and be electrically connected to the control terminal inside the switch assembly, wherein the control terminal is a limit switch 275.

[0044] In this embodiment, one end of the sound signal transmission line 7 is electrically connected to the control board 19, and the other end of the sound sensor 6 passes through the electrical protection box assembly 1 and then through the screw lifting assembly 8, and is electrically connected to the sound sensor 6 located away from the geared motor assembly 16. The sound sensor 6 is fixed at any location away from the geared motor assembly.

[0045] During use, depending on the shape and type of the items to be placed, users can fix various storage hardware on the lifting rack and let it rise or fall with the lifting rack. Users can also quickly replace different storage hardware themselves, and it is also convenient for users to remove the storage hardware for cleaning.

[0046] Example 1, as Figure 10 In this design, a lower storage box 30 and an upper storage box 29 are fixedly placed on the lifting bracket, which makes better use of space and allows for the storage of more items. The storage boxes rise and fall with the lifting bracket, making it easier for users to access and put away items.

[0047] Example 2, as Figure 11 In the middle, a back hanging plate 32 is fixedly placed on the lifting bracket. The back hanging plate has an integrally set hanging groove, on which a movable storage box 31 is hung. The movable storage box can be hung on any hanging groove, and multiple movable storage boxes can be set at the same time, which makes it convenient for users to store items with large differences in height and shape. At the same time, other functional hardware can be hung on the back plate to place corresponding items.

[0048] Example 3, as Figure 12 In the middle, the functional storage hardware 33 is hung on the lifting bracket via hooks 34. The functional storage hardware 33 rises or falls with the lifting bracket. The functional storage hardware 33 can be easily removed for cleaning. Users can also replace the corresponding functional storage hardware according to different items to be stored.

[0049] Working principle: When the geared motor assembly receives an external signal and power supply, it starts to rotate clockwise or counterclockwise. The worm gear integrated on the motor drives the worm wheel to rotate clockwise or counterclockwise. The worm wheel drives the screw to rotate synchronously. The screw drives the slider nut to move up and down. The lifting frame body, which is fixedly connected to the slider nut, rises or falls synchronously.
