[0069] See also Figure 1 As shown, the utility model provides a wall-locking lifting device, which includes a driving component 10 , a moving component 20 , a guiding component 30 and a control line 40 .

[0070] See also Figure 2As shown, the driving component 10 mainly includes an electric motor 11, a reduction gear box 12 (the internal structure is not shown in the figure), and a lead screw 13. The electric motor 11 is connected to the reduction gear box 12 in an upright manner. One end of the lead screw 13 is connected to a gear (not shown in the figure) in the aforementioned reduction gear box 12, and is sleeved and supported in the aforementioned reduction gear box 12 through a bearing (not shown in the figure) in the aforementioned reduction gear box 12. The other end of the lead screw 13 extends upright in a direction away from the reduction gear box 12 and is parallel to the aforementioned electric motor 11. The electric motor 11 has a worm (not shown in the figure), and the aforementioned reduction gear box 12 also has a turbine (not shown in the figure). The worm and the turbine, the turbine and the gear (not shown in the figure) are meshed with each other to drive the aforementioned lead screw 13 to rotate.

[0071] Please continue reading Figure 3 As shown, the movable member 20 is operably connected to the aforementioned driving member 10. The movable member 20 mainly includes a sheet 21, a sleeve 22 and a nut 23. The sleeve 22 is provided with a plurality of first through holes 221. The nut 23 also has a plurality of first threaded holes 232 corresponding to the aforementioned first through holes 221, and the nut 23 is fixed in the sleeve 22 by a plurality of first fasteners 201.

[0072] Furthermore, the nut 23 is provided with a screw hole 231 which is mutually screwed and driven with the lead screw 13, and the sheet 21 is welded and fixed at the center line position of the front side of the sleeve 22, parallel to the lead screw 13, and driven by the lead screw 13 of the driving member 10, so that the sheet 21 can move up and down along the lead screw 13. The nut 23 is fixed in the sleeve 22 by a plurality of screws.

[0073] Please continue reading Figure 1 , Figure 4 As shown, the guide member 30 is used to fix the aforementioned driving member 10, wherein the guide member 30 mainly includes a lower wall lock 31, an upper wall lock 32, two linear optical axis guide rails 33, two linear bearing box sliders 34, a bearing seat 35, multiple nuts 301, multiple fourth fasteners 302, multiple third fasteners 303, multiple second fasteners 304, multiple line clips 305 and multiple fifth fasteners 306.

[0074] Please continue reading Figure 4As shown, the lower wall lock 31 is a C shape, and the upper wall lock 32 is an L shape, but it is not limited to this shape. They can also be C-shaped or other geometric shapes. The lower wall lock 31 is provided with two fifth through holes 311, multiple fourth through holes 312, a lower opening 313 and a fourth threaded hole 314, and the upper wall lock 32 is provided with two third through holes 321, multiple third threaded holes 322 and an upper opening 323. The two linear optical axis guides 33 are of the same length, and both ends are provided with threaded sections 331 that are smaller than the diameter of the linear optical axis guides 33 and the threaded sections 331 have the same thread length. The linear bearing box slider 34 is provided with multiple second through holes 341 and a fifth threaded hole 343 and has multiple rows of bearing steel balls 342 on the inner side.

[0075] Furthermore, the fifth through hole 311 and the third through hole 321 are circular holes with the same diameter and the same distance between their respective circular axis cores. The fifth through hole 311 corresponds to the third through hole 321 one by one. The two linear optical axis guide rails 33 are each inserted into a linear bearing box-type slider 34. The threaded sections 331 at one end of the two linear optical axis guide rails 33 are respectively inserted into the third through hole 321 and fixedly connected to the upper wall locking piece 32 through the nut 301. The threaded sections 331 at the other ends of the two linear optical axis guide rails 33 are respectively inserted into the fifth through hole 311 and fixedly connected to the lower wall locking piece 31 through the nut 301. The two linear optical axis guide rails 33 are arranged in parallel. It should be noted here that the diameters of the third through hole 321 and the fifth through hole 311 are the same and smaller than the diameter of the linear optical axis guide rail 33 but larger than the diameter of the thread of the threaded section 331, and the depths of the third through hole 321 and the fifth through hole 311 are the same and smaller than the length of the thread of the threaded section 331, thereby ensuring that the upper wall locking member 32 and the lower wall locking member 31 are located at both ends of the two linear optical axis guide rails 33 and the relative surfaces are parallel.

[0076] See also Figure 1 , Figure 3 , Figure 4 As shown, the lead screw 13 spans the opening of the upper wall lock 32 and the opening of the lower wall lock 31, and the upper end is sleeved in the bearing seat 35. Specifically, the lead screw 13 spans the upper opening 323 and the lower opening 313, and the top end is sleeved in the bearing seat 35. The third fastener 303 connects and fixes the bearing seat 35 and the upper wall lock 32 through the third threaded hole 322, and the fourth fastener 302 connects and fixes the driving member 10 and the lower wall lock 31 through the threaded hole (not shown in the figure) at the bottom of the reduction gear box 12. When the lead screw 13 rotates, the bearing seat 35 fixed on the upper wall lock 32 can stabilize the lead screw 13, so that the lead screw 13 runs more stably and has a longer service life.

[0077] Furthermore, the sleeve 22 also has a plurality of second threaded holes 223 corresponding one to one with the second through holes 341, and the sleeve 22 is connected and fixed in the middle of two parallel linear bearing box sliders 34 through a plurality of second fasteners 304. The linear bearing box sliders 34 are respectively fixed on the left and right sides of the sleeve 22. The linear bearing box sliders 34 are between the sleeve 22 and the linear optical axis guide rail 33. The sleeve 22 slides up and down along the linear optical axis guide rail 33 through the bearing steel balls 342. The nut 23 is between the lead screw 13 and the sleeve 22. The nut 23 is driven by the rotation of the lead screw 13 so that the sheet 21 on the movable member 20 can be stably moved up and down on the two parallel linear optical axis guide rails 33.

[0078] See also Figure 2 , Figure 3 , Figure 4 As shown, a bayonet 222 is further provided on the top of the sleeve 22, and the control line 40 has a spiral winding 41, which defines an axis line, and the axis line is arranged parallel to the lead screw 13 and the linear optical axis guide rail 33. A wire sleeve 42 is provided on the upper part of the spiral winding 41 to be engaged with the aforementioned bayonet 222, and the linear bearing box slider 34 and the lower wall lock 31 on the same side as the control line 40 are also respectively provided with at least one wire clip 305.

[0079] Furthermore, the wire sleeve 42 has two clamping rings arranged at 90 degrees to each other, which are clamped and fixed with the bayonet 222, so as to avoid friction between the control wire 40 and the rotating lead screw 13 in the sleeve 22, and allow the control wire 40 to turn from the left side of the sleeve 22 to the front side of the sleeve 22 and be parallel to the sheet body 21. The upper straight section of the spiral winding wire 41 is connected and fixed to the fifth threaded hole 343 on the left side of the linear bearing box slider 34 on the same side through the wire clamp 305, and the lower straight section of the spiral winding wire 41 is connected and fixed to the fourth threaded hole 314 at the bottom of the lower wall locking member 31 through the wire clamp 305. The spiral winding wire 41 is retractable. When the driving component 10 drives the moving component 20 to move up and down through the lead screw 13, the upper straight section of the spiral winding wire 41 moves up and down synchronously with the moving component 20, so as to avoid friction and entanglement between the control wire 40 and the driving component 10.

[0080] See also Figure 5 As shown, two sets of wall-locked lifting devices can be used to cooperate with a wall 60 and a table 50 to be connected, and the wall-locked lifting devices are connected and fixed to the wall 60 through multiple fifth fasteners 306. After each sheet 21 and the control line 40 pass through the preset strip groove 61 of the wall 60 and are driven by the driving component 10, the table 50 can adapt to different usage requirements and can be adjusted to an appropriate usage height.

[0081] In summary, the wall-locked lifting device of the utility model can indeed achieve the intended purpose of use and solve the existing deficiencies. Moreover, because it is extremely creative and progressive, it fully meets the requirements for utility model patent applications, and therefore an application is filed in accordance with the Patent Law.
