[0067] The structural principle and working principle of the present invention will be described in detail below with reference to the accompanying drawings.

[0068] The detailed description and technical contents of the present invention are described below with reference to the accompanying drawings. However, the drawings are only provided for reference and explanation and are not intended to limit the present invention.

[0069] 1 , the present invention provides a wall-locking lifting device, which includes a driving member 10 , a moving member 20 , a guide member 30 and a control wire 40 .

[0070] Please refer to Figure 2. 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 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, and the turbine and the gear (not shown in the figure) are engaged with each other to drive the aforementioned lead screw 13 to rotate.

[0071] Please continue to refer to Figure 3. The movable member 20 is operably connected to the aforementioned driving member 10. The movable member 20 mainly includes a piece 21, a sleeve 22 and a nut 23. The sleeve 22 has 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 for threaded connection with the aforementioned lead screw 13. The plate 21 is welded and fixed to the centerline of the front side of the sleeve 22, parallel to the lead screw 13, and is driven by the lead screw 13 of the driving member 10, so that the plate 21 can move up and down along the lead screw 13. The nut 23 is fixed to the sleeve 22 by multiple screws.

[0073] 1 and 4 , 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 , a plurality of nuts 301 , a plurality of fourth fasteners 302 , a plurality of third fasteners 303 , a plurality of second fasteners 304 , a plurality of line clips 305 and a plurality of fifth fasteners 306 .

[0074] 4 , the lower locking member 31 is C-shaped, and the upper locking member 32 is L-shaped, but the shapes are not limited thereto. Both may be C-shaped or other geometric shapes. The lower locking member 31 is provided with two fifth through holes 311, a plurality of fourth through holes 312, a lower opening 313, and a fourth threaded hole 314. The upper locking member 32 is provided with two third through holes 321, a plurality of third threaded holes 322, and an upper opening 323. The two linear optical axis guide rails 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 guide rails 33 and have the same thread length. The linear bearing box slider 34 is provided with a plurality of 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 aforementioned 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 end 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 aforementioned 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. 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 the two ends of the two linear optical axis guide rails 33 and the relative surfaces are parallel.

[0076] As shown in Figures 1, 3, and 4, the lead screw 13 spans the openings of the upper lock member 32 and the lower lock member 31, with its upper end sleeved in the bearing seat 35. Specifically, the lead screw 13 spans the upper opening 323 and the lower opening 313, with its top end sleeved in the bearing seat 35. A third fastener 303 secures the bearing seat 35 to the upper lock member 32 via a third threaded hole 322. A fourth fastener 302 secures the drive member 10 to the lower lock member 31 via a threaded hole (not shown) in the bottom of the reduction gearbox 12. The bearing seat 35 secured to the upper lock member 32 stabilizes the lead screw 13 as it rotates, ensuring more stable operation and 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] Please refer to Figures 2, 3 and 4. A bayonet 222 is further provided on the top of the sleeve 22. The control line 40 has a spiral winding 41. The spiral winding 41 defines an axis. The axis 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. 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 lead screw 13 rotating 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 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 41 is connected and fixed to the fourth threaded hole 314 at the bottom of the lower wall lock 31 through the wire clamp 305. The spiral winding 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 41 moves up and down synchronously with the moving component 20, avoiding friction and entanglement between the control wire 40 and the driving component 10.

[0080] As shown in FIG. 5 , two sets of wall-locked lifting devices can be used to cooperate with a wall 60 and a table 50 to connect with each other. The wall-locked lifting devices are connected and fixed to the wall 60 via a plurality of fifth fasteners 306 . Each plate 21 and the control line 40 pass through a preset strip groove 61 in the wall 60 and are driven by the driving member 10 . This allows the table 50 to be adjusted to an appropriate height to meet various usage requirements.

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

[0082] Of course, the present invention may have many other embodiments.
