Detailed Implementation

[0031] The technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of this utility model. Example 1

[0032] like Figure 1-9As shown, a concealed height-adjustable light box structure includes a riser 1, a height-adjusting sleeve 2, a light box 3, and a decorative cover plate 4. There are three risers 1, and each riser 1 is equipped with a layer of height-adjusting sleeve 2, that is, the height position of the height-adjusting sleeve 2 on each riser 1 is the same. The light box 3 has a layer of height-adjusting sleeve 2 that is fitted on the three risers, so that the upper part of the height-adjusting sleeve 2 is inside the light box 3, and the bottom is outside the light box 3 and is used to support the light box 3. The upper surface of the light box 3 is provided with a decorative cover plate 4.

[0033] Each riser 1 has several longitudinally arranged adjustment holes 11, and each height adjustment sleeve 2 (such as...) Figure 9 The upper part of each of the height adjustment sleeves 2 and the corresponding riser 1 is provided with a wire hole 21 and a connection hole 22. Each height adjustment sleeve 2 is fitted on the outside of the corresponding riser 1 and is connected to any one of the adjustment holes 11 by fasteners passing through the connection hole 22. The fasteners used here are the commonly used external hex bolts or pan head screws in the prior art. After adjusting the position of the corresponding height adjustment sleeve 2, the height adjustment sleeve 2 is locked to the riser 1 by external hex bolts or pan head screws to complete the position adjustment. The specific locking method will not be described in detail.

[0034] The power cord of the light box 3 (not shown in the figure) passes through the wire hole 21 on any height adjustment sleeve 2, extends into the adjustment hole 11 near it, enters the riser 1, and is led out of the riser 1 to connect with the circuit above the ceiling (not shown in the figure). The wiring method of the power cord of the light box 3 can achieve the effect of hiding the wire, without running the wire outside the pipe, which improves the aesthetics.

[0035] Specifically, the top and bottom surfaces of the lamp box 3 are respectively provided with a first through hole and a second through hole, and the bottom of the height adjustment sleeve 2 is provided with a ring-shaped lower support part 23, which is used to support the bottom surface of the lamp box 3. The ring-shaped lower support part 23 can not only support the lamp box 3, but also block the second through hole on the bottom surface of the lamp box 3 to prevent dust from entering the lamp box through the second through hole.

[0036] The top of the height adjustment sleeve 2 is provided with a ring-shaped upper support part 24. The inner diameter of the second through hole is larger than the outer diameter of the upper support part 24, and the outer diameter of the upper support part 24 is larger than the inner diameter of the first through hole. The upper support part 24 is used to support the top surface of the lamp box 3. The ring-shaped upper support part 24 can not only support the lamp box 3, but also block the first through hole on the top surface of the lamp box 3 to prevent dust from entering the lamp box through the first through hole.

[0037] Specifically, in this embodiment, each layer of the light box 3 includes an acrylic base plate 31, a lamp holder 32, an inner LED light 33, an outer peripheral profile light 34, and a sealing plate 35. The bottom of the acrylic base plate 31 is supported by a lower support part 23. The lamp holder 32 is disposed on the acrylic base plate 31 and supported by an upper support part 24. There are two sealing plates 35, which are respectively disposed on both sides of the lamp holder 32.

[0038] The upper part of the lamp holder 32 is provided as a boss 321 and a wire hole 3211 is provided on the outer wall of the boss 321. The inner LED light 33 is provided on the acrylic base plate 31 and located inside the lamp holder 32. The power cord of the inner LED light 33 (not shown in the figure) extends into the wire hole 21 and the adjustment hole 11 and is led out from the upper part of the riser 1. The outer profile light 34 is provided on the outer side of the boss 321 and its power cord (not shown in the figure) passes through the wire hole 3211, extends into the wire hole 21 and the adjustment hole 11 and is led out from the upper part of the riser 1.

[0039] Wiring procedure: Push up light box 3 (e.g.) Figure 8 As shown), the wire hole 21 on the height adjustment sleeve 2 is exposed. The power cords of the inner LED lights 33 can be gathered together and twisted together. Then, the main power cord (not shown in the figure) is exposed along the second through hole on the bottom of the light box. Then, the riser is laid flat. The main power cord (not shown in the figure) is held and inserted into the adjustment hole 11 through the wire hole 21 and into the riser 1. The wire is pushed forward until it extends out of the tube. Then, it is connected to the ceiling.

[0040] The structure of the light box 3 facilitates the assembly of the inner LED light 33 and the outer profile light 34. The assembled inner LED light 33 can emit light through the acrylic base plate 31, which, combined with the light from the outer profile light 34, makes the light box more aesthetically pleasing overall.

[0041] Specifically, in this embodiment, as Figure 6 As shown, the lamp holder 32 is composed of two lamp holders connected together. The junction of the two lamp holders forms a first through hole, through which a vertical tube 1 is inserted. That is, a vertical tube is inserted at the junction in the figure. In this embodiment, three vertical tubes are used to install the lamp box. Here, the connection can be achieved by existing common technical means, such as insert type installation or pin type installation. This embodiment does not have a special structure, and the specific structure and installation method will not be described in detail.

[0042] Specifically, in this embodiment, the top of each riser 1 extends into a pre-drilled hole in the ceiling and is installed on the ceiling through a fixing seat 5, while the bottom is fitted onto the ground round pipe 6, which is fixed to the ground by expansion screws 7.

[0043] Specifically, in this embodiment, each decorative cover plate 4 is limited above by a pressure seat 8. The pressure seat 8 is sleeved on the outside of the riser 1 and fixed to the riser 1 by a set screw. A buffer pad 9 is provided between the pressure seat 8 and the decorative cover plate 4. Here, the use of the pressure seat can prevent the riser from rotating and can also further limit the position of the light box. The set screw can be an M3 socket head cap screw, which is relatively small and has good concealment.

[0044] The installation process is as follows:

[0045] First, install the height adjustment sleeve according to the required height position of the light box 3. Then, fix the height adjustment sleeve 2 to the riser 1 with fasteners. Then, put the light box 3 into the riser 1 from top to bottom. Insert the power cord of the light box 3 into the riser 1 through the wire hole and adjustment hole inside the light box 3 and then lead it out from the top.

[0046] Then, insert the decorative cover plate 4, buffer pad 9, and pressure seat 8 into the riser 1 in sequence. Use set screws to lock the pressure seat 8 to prevent the riser 1 from rotating. Finally, stand the assembled product upright, connect the wires, and test the light. After everything is normal, wrap the connector with solder and insert it into the reserved hole in the ceiling. Place the transformer in a maintenance position on the ceiling. Then, align the upper end of the product's riser with the reserved hole in the ceiling and insert it. Continue to raise the product and then align it with the round tube 6 on the ground and lower it down to complete the fixing of the riser 1 to the ground, thus completing the installation of this utility model. Example 2

[0047] like Figure 10 As shown, unlike Embodiment 1, the product's light box has three layers. Of course, each riser also has three layers of height adjustment sleeves. The assembly method of this embodiment is to assemble the bottom layer of the product first, then assemble the middle layer of the product, and finally assemble the top layer of the product. The specific installation structure of each layer of the light box is the same as described above, and will not be described in detail again.

[0048] The above-disclosed embodiments are merely two examples of this utility model and should not be construed as limiting the scope of this utility model. Therefore, any equivalent variations made in accordance with the claims of this utility model are still within the scope of this utility model.
