[0007] Furthermore, the support body has a receiving cavity with an opening at the bottom, and the adjustment component and the drive component are both located inside the receiving cavity.

[0008] Furthermore, the height adjustment device also includes a limiting component. The adjusting screw is mounted on the support base, and the limiting component limits the adjusting block and the driving component within the receiving cavity to restrict their vertical movement within the receiving cavity.

[0009] Furthermore, the limiting assembly includes a top plate and a bottom plate, with an adjusting block and a driving component sandwiched between the top plate and the bottom plate.

[0010] Furthermore, a positioning ring is provided on the base plate, and a positioning shaft is provided at the lower end of the drive component, with the positioning shaft rotatably disposed within the positioning ring.

[0011] Furthermore, the top plate is provided with a clearance hole corresponding to the drive hole, the upper end of the drive component is provided with a drive shaft, the drive shaft passes upward through the clearance hole and extends into the drive hole, and the upper surface of the drive shaft is provided with a drive recess that cooperates with the drive tool.

[0012] Furthermore, the side of the support body has a concave portion, the top plate cooperates with the bottom wall of the concave portion, and the top plate is fixed in the receiving cavity by a first fastener passing through the bottom wall of the concave portion and the top plate; and / or, the lower end of the support body is provided with a boss portion, the bottom plate cooperates with the top wall of the boss portion, and the bottom plate is fixed in the receiving cavity by a second fastener passing through the top wall of the boss portion and the bottom plate.

[0016] The height adjustment device, utilizing the technical solution of this utility model, includes a support base, a support body, an adjustment component, and a driving component. The support base is positioned on the ground, and the support body is positioned above the support base to support the corners of the LED display cabinet. The adjustment component and the driving component are positioned between the support base and the support body. Through the cooperation of the adjustment component and the driving component, the support body can be raised or lowered relative to the support base. If the LED display is found to be uneven during installation, the user can use a driving tool to rotate the driving component, which in turn rotates the adjustment block, causing the adjustment block to move up and down along the length of the adjustment screw, thereby raising or lowering the support body relative to the support base.

[0037] like Figure 1 and Figure 6 As shown, this application provides a height adjustment device. An embodiment of the height adjustment device includes a support base 10, a support body 20, an adjustment assembly 30, and a driving member 40. The support body 20 is disposed above the support base 10. The adjustment assembly 30 includes an adjustment screw 31 and an adjustment block 32. The adjustment block 32 has a threaded hole 321, through which the adjustment screw 31 passes. One of the adjustment screw 31 and the adjustment block 32 is disposed on the support base 10, and the other is disposed on the support body 20. The driving member 40 is disposed on the side of the adjustment assembly 30. The driving member 40 drives and cooperates with the adjustment block 32, enabling the adjustment block 32 to rotate, thus allowing the support body 20 to rise or fall relative to the support base 10. The top of the support body 20 has a driving hole 21 corresponding to the driving member 40, allowing a driving tool 1 to pass through the driving hole 21 and cooperate with the driving member 40.

[0038] Using the technical solution of this embodiment, the height adjustment device includes a support base 10, a support body 20, an adjustment component 30, and a drive component 40. The support base 10 is set on the ground, and the support body 20 is set above the support base 10 to support the corners of the LED display cabinet 2. The adjustment component 30 and the drive component 40 are set between the support base 10 and the support body 20. Through the cooperation of the adjustment component 30 and the drive component 40, the support body 20 can be raised or lowered relative to the support base 10. If the screen is found to be uneven during the installation of the LED display, the user can use the drive tool 1 to drive the drive component 40 to rotate, which in turn causes the drive component 40 to drive the adjustment block 32 to rotate, so that the adjustment block 32 moves up and down along the length direction of the adjustment screw 31, thereby raising or lowering the support body 20 relative to the support base 10. In this embodiment, by setting the drive component 40 on the side of the adjustment component 30, when the screen is found to be uneven, it is only necessary to remove the LED display cabinet 2 located above the drive component 40 to expose the drive hole 21, so as to adjust the height of the height adjustment device to make the LED display flat. Compared to related technologies that require the removal of all LED display cabinets supported by the height adjustment device, this embodiment only requires the removal of one LED display cabinet 2, greatly reducing the workload during height adjustment. Therefore, the technical solution of this embodiment can effectively solve the problem that the height adjustment device in related technologies cannot meet the needs of rapid installation.

[0039] like Figure 1 As shown, in this embodiment, the adjusting screw 31 is disposed on the support base 10, and the adjusting block 32 is disposed on the support body 20; in an embodiment not shown in the figure, the adjusting block is disposed on the support base, and the adjusting screw is disposed on the support body.

[0040] like Figures 2 to 4 As shown, the support body 20 has a receiving cavity 22 with a lower opening, and the adjustment component 30 and the drive component 40 are both disposed within the receiving cavity 22. This arrangement facilitates the installation of the adjustment component 30 and the drive component 40 inside the support body 20, prevents the adjustment component 30 and the drive component 40 from being directly exposed to the external environment, and effectively protects the adjustment component 30 and the drive component 40.

[0041] like Figure 1 , Figure 4 and Figure 6As shown, the height adjustment device also includes a limiting component 50. The adjusting screw 31 is mounted on the support base 10. The limiting component 50 limits the adjusting block 32 and the driving member 40 within the receiving cavity 22, thereby restricting their vertical movement within the cavity 22. By limiting the adjusting block 32 and the driving member 40 within the receiving cavity 22 of the support body 20 through the limiting component 50, when the user rotates the driving member 40 using the driving tool 1, thereby causing the adjusting block 32 to rotate, the adjusting block 32 moves vertically along the length of the adjusting screw 31. Since the adjusting block 32 is limited within the receiving cavity 22, the support body 20 also moves vertically along the length of the adjusting screw 31, thus achieving the height adjustment function.

[0042] Specifically, the limiting component 50 only restricts the movement of the adjusting block 32 and the driving member 40 in the vertical direction, and does not restrict the rotation of the adjusting block 32 and the driving member 40.

[0043] like Figure 1 and Figure 4 As shown, the limiting assembly 50 includes a top plate 51 and a bottom plate 52, with the adjusting block 32 and the driving component 40 sandwiched between the top plate 51 and the bottom plate 52. This arrangement effectively limits the adjusting block 32 and the driving component 40 within the receiving cavity 22 of the support body 20, offering advantages such as simple structure and ease of installation.

[0044] Specifically, the top plate 51 has a first through hole 512 for the adjusting screw 31 to pass through, and the bottom plate 52 has a second through hole 522 for the adjusting screw 31 to pass through. By providing the first through hole 512 and the second through hole 522, interference between the top plate 51 and the bottom plate 52 and the adjusting screw 31 can be prevented, thereby allowing the support body 20 to move up and down relative to the support base 10. The first through hole 512 and the second through hole 522 are coaxially arranged with the threaded hole 321 of the adjusting block 32 so that the adjusting screw 31 can smoothly pass through the second through hole 522, the threaded hole 321 and the first through hole 512.

[0045] It should be noted that, Figure 4 The figure shows the lowest height state of the height adjustment device. In this state, the bottom plate 52 of the limiting component 50 of the height adjustment device is in contact with the support seat 11 of the support base 10. When the user needs to adjust the height of the LED display cabinet 2, the support body 20 can be moved up and down by the drive tool 1.

[0046] like Figure 1 and Figure 4As shown, a positioning ring 521 is provided on the base plate 52, and a positioning shaft 41 is provided at the lower end of the drive member 40. The positioning shaft 41 is rotatably disposed within the positioning ring 521. By providing a positioning ring 521 on the base plate 52 and a positioning shaft 41 at the lower end of the drive member 40, it is convenient to install the base plate 52 and the drive member 40. At the same time, during the height adjustment of the support body 20, the cooperation between the positioning shaft 41 and the positioning ring 521 can prevent lateral displacement of the drive member 40 during rotation.

[0047] like Figure 1 , Figure 4 and Figure 6 As shown, the top plate 51 is provided with a clearance hole 511 corresponding to the drive hole 21. The upper end of the drive member 40 is provided with a drive shaft 42. The drive shaft 42 passes upward through the clearance hole 511 and extends into the drive hole 21. The upper surface of the drive shaft 42 is provided with a drive recess 421 that cooperates with the drive tool 1. By providing a clearance hole 511 on the top plate 51, the drive shaft 42 can pass through the clearance hole 511 and extend into the drive hole 21, thereby allowing the drive tool 1 to extend into the drive recess 421 and drive the drive member 40 to rotate, so as to realize the height adjustment of the support body 20.

[0048] It should be noted that the drive recess 421 on the drive component 40 can be configured as a slotted slot, a square slot, a hexagonal slot, or an octagonal slot, etc., and the drive tool 1 that matches the drive recess 421 can be a matching slotted wrench, a square wrench, a hexagonal wrench, or an octagonal wrench, etc.

[0049] like Figure 2 , Figure 3 and Figure 6 As shown, the side of the support body 20 has a recess 23. The top plate 51 is stopped by the bottom wall of the recess 23. The top plate 51 is fixed in the receiving cavity 22 by a first fastener 60 that passes through the bottom wall of the recess 23 and the top plate 51. By providing a recess 23 on the side of the support body 20, when the top plate 51 is placed into the receiving cavity 22, the bottom wall of the recess 23 is stopped by the top plate 51, realizing the quick positioning and installation of the top plate 51. This allows the top plate 51 to limit the adjustment block 32 and the driving component 40. The first fastener 60 can fix the recess 23 and the top plate 51, preventing the top plate 51 from moving during the adjustment of the height of the support body 20.

[0050] like Figure 2 and Figure 4As shown, a boss 24 is provided at the lower end of the support body 20. The bottom plate 52 is engaged with the top wall of the boss 24. The bottom plate 52 is fixed in the receiving cavity 22 by a second fastener 70 passing through the top wall of the boss 24 and the bottom plate 52. By providing a boss 24 at the lower end of the support body 20, when the bottom plate 52 is placed into the receiving cavity 22, the top wall of the boss 24 engages with the bottom plate 52, enabling quick positioning and installation of the bottom plate 52. This allows the bottom plate 52 to limit the adjustment block 32 and the driving component 40. The second fastener 70 can fix the boss 24 and the bottom plate 52, preventing the bottom plate 52 from shifting during the adjustment of the height of the support body 20.

[0051] like Figure 1 and Figure 5 As shown, the height adjustment device includes multiple driving elements 40, and multiple driving holes 21 are provided on the support body 20. The multiple driving elements 40 and multiple driving holes 21 are arranged along the circumferential direction of the adjustment assembly 30. By providing multiple driving elements 40 and corresponding multiple driving holes 21, the height of the support body 20 can be adjusted by any one of the driving elements 40.

[0052] Preferably, in this embodiment, when the number of driving components 40 is the same as the number of LED display cabinets 2 supported by the supporting body 20, and multiple driving components 40 are arranged one-to-one with the corners of multiple LED display cabinets 2, the LED display screen can be leveled by disassembling any one of the LED display cabinets 2.

[0053] like Figure 1 and Figure 5 As shown, the driving component 40 is the first gear, and the adjusting block 32 is the second gear that meshes with the first gear. The driving component 40 and the adjusting block 32 adopt a gear structure, which has the advantages of simple structure and reliable transmission.

[0054] like Figure 7 and Figure 8 As shown, this application also provides an LED display screen. An embodiment of the LED display screen of this application includes a height adjustment device and an LED display cabinet 2, wherein the height adjustment device is the aforementioned height adjustment device. The aforementioned height adjustment device can effectively solve the problem that height adjustment devices in related technologies cannot meet the needs of rapid installation, and the LED display screen with the aforementioned height adjustment device also has the aforementioned advantages.

[0055] like Figure 7 and Figure 8 As shown, the LED display screen also includes connecting rods 3, and the support body 20 is provided with multiple connecting arms 80 along the circumference. The connection between the connecting rods 3 and the connecting arms 80 enables multiple support bodies 20 to be connected with multiple connecting rods 3 to form a grid-like support frame. The LED display cabinet 2 is located above the support frame.

[0056] In the description of this utility model, it should be understood that "multiple" means two or more. Directional terms such as "front, back, up, down, left, right," "horizontal, vertical, perpendicular, horizontal," and "top, bottom" indicate directions or positional relationships based on the directions or positional relationships shown in the accompanying drawings. These terms are used solely for the convenience of describing this utility model and simplifying the description. Unless otherwise stated, these directional terms do not indicate or imply that the device or element referred to must have a specific orientation or be constructed and operated in a specific orientation, and therefore should not be construed as limiting the scope of protection of this utility model. The directional terms "inner" and "outer" refer to the inner or outer contours relative to the outline of each component itself.

[0057] For ease of description, spatial relative terms such as "above," "on top of," "on the upper surface of," "above," etc., are used herein to describe the spatial positional relationship of a device or feature as shown in the figures to other devices or features. It should be understood that spatial relative terms are intended to encompass different orientations in use or operation beyond the orientation of the device as described in the figures.
