[0003] The display boards of existing adjustable display racks are generally fixed to the surface of the mounting frame by screws. After multiple times of pasting notices or artworks, glue will remain on the surface of the display boards, which is difficult to remove and requires the display boards to be replaced as a whole. When removing the display boards from the surface of the mounting frame, all the screws need to be removed. It takes a long time to turn the screws to disassemble or install the display boards, which is not convenient enough. Therefore, improvements are needed. Utility Model Content

[0004] In order to overcome the above defects, the utility model provides an adjustable display stand, which solves the problem that the existing adjustable display stand needs to screw multiple sets of screws when disassembling or installing the display board, which takes a long time and is not convenient for disassembling or connecting the display board and the installation frame.

[0005] To achieve the above-mentioned purpose, the utility model provides the following technical solutions: an adjustable display rack, comprising an I-shaped bottom plate, universal wheels are fixedly installed at the four corners of the bottom of the I-shaped bottom plate, a mounting frame is fixedly installed on the top of the I-shaped bottom plate, a width adjustment mechanism is fixedly installed at the central position of both sides of the inside of the mounting frame, a height adjustment mechanism is symmetrically fixedly installed between the two sides of the width adjustment mechanism and the inner wall of the mounting frame, and a clamping mechanism is symmetrically slidably installed on both sides between the width adjustment mechanism and the two sets of height adjustment mechanisms;

[0006] The clamping mechanism includes a mounting block, a fixing stud is fixedly installed on one side of the mounting block, and a fixing nut is provided on the surface of the fixing stud, a clamping slide rod is symmetrically fixedly installed on the top and bottom of the mounting block, and an end plate is fixedly installed on one end of the clamping slide rod, a sliding block is slidably installed on the surface of the clamping slide rod, and a clamping protrusion is fixedly installed on one side of the sliding block, an exhibition plate is provided on the surface of the clamping protrusion, and a clamping spring is provided on the surface of the clamping slide rod between the mounting block and the sliding block.

[0007] As a further solution of the utility model: support columns are fixedly installed at the central positions on both sides of the top of the I-shaped base plate, and inclined support plates are symmetrically fixedly installed on both sides of the support columns on the top of the I-shaped base plate.

[0008] As a further solution of the utility model: the universal wheel comprises a rotating shaft, a mounting frame is fixedly mounted on the bottom of the rotating shaft, a brake lever is provided on one side of the top of the mounting frame, and a moving wheel is rotatably mounted on the bottom of the mounting frame.

[0009] As a further solution of the utility model: the width adjustment mechanism includes two groups of fixed blocks, and an adjustment plate is fixedly installed between the two groups of fixed blocks. The surface of the adjustment plate is provided with an adjustment slot, and the fixing stud passes through the adjustment slot.

[0010] As a further solution of the utility model: the height adjustment mechanism includes two groups of adjusting screws, the surface of the adjusting screws is provided with moving blocks, and an adjusting slide rod is fixedly installed between the two groups of moving blocks, and the surface of the adjusting screw on one side of the moving block close to the width adjustment mechanism is provided with an adjusting screw sleeve.

[0011] As a further solution of the utility model: U-shaped clamping blocks are fixedly installed at the four corners inside the display board, and a fixed clamping groove is provided on one side of the U-shaped clamping block, and the fixed clamping groove corresponds to the clamping protrusion.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The adjustable display frame is provided with a clamping slide bar, a clamping protrusion, a clamping spring, an exhibition board and a U-shaped clamping block. The sliding block is pressed toward the mounting block, so that the clamping spring is compressed and deformed between the sliding block and the mounting block, so that the distance between the two sets of clamping protrusions is reduced, and the exhibition board is covered on the surface of the mounting frame, so that the U-shaped clamping block corresponds to the sliding block, and it is ensured that the clamping protrusion corresponds to the fixed slot. When the sliding block is released, the sliding block is pushed to both sides under the rebound action of the clamping spring until the clamping protrusion is clamped into the corresponding fixed slot, so that it is convenient to clamp, fix or remove the exhibition board.

[0014] 2. The adjustable display rack is provided with an adjustment plate, an adjustment slot, a mounting block, a fixing stud and a fixing screw sleeve. The two sets of fixing screw sleeves are loosened, and the mounting blocks are dragged to both sides to make the fixing studs slide inside the adjustment slots until the two sets of mounting blocks are located at appropriate positions on one side of the adjustment plate. The fixing screw sleeves are tightened to clamp and fix the mounting blocks on the surface of the adjustment plate, so that the distance between the two sets of clamping mechanisms can be adjusted according to the width of the display board, thereby clamping and fixing the display boards of different widths.

[0015] 3. The adjustable display rack is provided with an adjusting screw, a moving block, an adjusting slide bar, an adjusting screw sleeve and a sliding block. The adjusting screw sleeve is screwed close to the fixed block so that the moving block can move on the surface of the adjusting screw, thereby controlling the adjusting slide bar to drive the sliding block to slide on the surface of the clamping slide bar. After the clamping protrusion is inserted into the corresponding fixed slot, the adjusting screw sleeve is tightened to fit the moving block to ensure that the sliding block does not drive the clamping protrusion to move toward the fixed block, causing the clamping protrusion to be separated from the fixed slot and cause the display board to fall off.

[0021] The technical solution of this patent is further described in detail below in conjunction with specific implementation methods.

[0022] like Figure 1-4 As shown, the utility model provides a technical solution: an adjustable display rack, including an I-shaped base plate 1, support columns 101 are fixedly installed at the central positions on both sides of the top of the I-shaped base plate 1, and inclined support plates 102 are symmetrically fixedly installed on both sides of the support columns 101 on the top of the I-shaped base plate 1. Because the inclined support plates 102 are provided, the inclined support plates 102 on both sides of the support columns 101 support the support columns 101, thereby preventing the display rack from tipping over easily due to the excessively high center of gravity of the installation frame 3 on the top of the support columns 101.

[0023] Universal wheels 2 are fixedly installed at the four corners of the bottom of the I-shaped base plate 1. The universal wheels 2 include a rotating shaft 201. A mounting frame 202 is fixedly installed at the bottom of the rotating shaft 201, and a brake lever 203 is provided on one side of the top of the mounting frame 202. A moving wheel 204 is rotatably installed at the bottom of the mounting frame 202. Because the universal wheels 2 are provided, the mounting frame 3 is pushed to roll with the universal wheels 2. After the mounting frame 3 is moved to different positions, the brake lever 203 is stepped on to clamp and fix the moving wheel 204 to ensure that the universal wheel 2 does not slide and cause the display frame to move.

[0024] A mounting frame 3 is fixedly installed on the top of the I-shaped base plate 1, and a width adjustment mechanism 4 is fixedly installed at the central position on both sides of the inside of the mounting frame 3. The width adjustment mechanism 4 includes two groups of fixed blocks 401, and an adjustment plate 402 is fixedly installed between the two groups of fixed blocks 401. An adjustment groove 403 is provided on the surface of the adjustment plate 402, and a fixed stud 602 passes through the adjustment groove 403. Due to the provision of the adjustment groove 403, the fixed stud 602 slides inside the adjustment groove 403, thereby facilitating the adjustment of the distance between the two groups of clamping mechanisms 6 according to the width of the display board 7.

[0025] A height adjustment mechanism 5 is symmetrically fixedly installed between the two sides of the width adjustment mechanism 4 and the inner wall of the mounting frame 3. The height adjustment mechanism 5 includes two groups of adjusting screws 501. A moving block 502 is provided on the surface of the adjusting screw 501, and an adjusting slide bar 503 is fixedly installed between the two groups of moving blocks 502. An adjusting screw sleeve 504 is provided on the surface of the moving block 502 close to the width adjustment mechanism 4. By providing the adjusting screw sleeve 504, after the clamping mechanism 6 clamps and fixes the exhibition board 7, the adjusting screw sleeve 504 is screwed to fit the moving block 502 to ensure that the moving block 502 does not move toward the fixed block 401, thereby preventing the clamping protrusions 606 from approaching each other and causing the exhibition board 7 to detach from the mounting frame 3.

[0026] Clamping mechanisms 6 are symmetrically slidably installed on both sides between the width adjustment mechanism 4 and the two sets of height adjustment mechanisms 5; the clamping mechanism 6 includes a mounting block 601, a fixing stud 602 is fixedly installed on one side of the mounting block 601, and a fixing screw sleeve 603 is provided on the surface of the fixing stud 602. By providing the fixing screw sleeve 603, the fixing stud 602 slides inside the adjustment slide groove 403 until the two sets of clamping mechanisms 6 are located at the appropriate position of the adjustment plate 402, and then the fixing screw sleeve 603 is tightened to ensure that the mounting block 601 is clamped and fixed at the appropriate position on the surface of the adjustment plate 402 without sliding;

[0027] The top and bottom of the mounting block 601 are symmetrically fixedly installed with clamping slide bars 604, and one end of the clamping slide bar 604 is fixedly installed with an end plate 608, a sliding block 605 is slidably installed on the surface of the clamping slide bar 604, and a clamping protrusion 606 is fixedly installed on one side of the sliding block 605, a display board 7 is provided on the surface of the clamping protrusion 606, a U-shaped clamping block 701 is fixedly installed at the four corners inside the display board 7, and a fixed slot 702 is provided on one side of the U-shaped clamping block 701, and the fixed slot 702 corresponds to the clamping protrusion 606, by providing the clamping protrusion 606 and the fixed slot 702, after the clamping protrusion 606 is clamped into the corresponding fixed slot 702, the display board 7 is clamped and fixed, ensuring that the clamping protrusion 606 will not be misaligned when it is clamped into the corresponding fixed slot 702.

[0028] A clamping spring 607 is provided on the surface of the clamping slide rod 604 between the mounting block 601 and the sliding block 605. Because of the clamping spring 607, loosening the clamping spring 607 will push the sliding block 605 in a direction away from the mounting block 601, ensuring that the sliding block 605 can drive the clamping protrusion 606 to be clamped into the corresponding fixed slot 702.

[0029] The working principle of the utility model is:

[0030] Loosen the two sets of fixing screw sleeves 603, adjust the distance between the two sets of clamping mechanisms 6 according to the distance between the U-shaped clamping blocks 701 inside the display board 7, make the fixing studs 602 slide inside the adjusting slide grooves 403, until the two sets of clamping mechanisms 6 correspond to the U-shaped clamping blocks 701, tighten the fixing screw sleeves 603 to fix the clamping mechanisms 6 on the surface of the adjusting plate 402, turn the adjusting screw sleeves 504 close to the fixing block 401, press the moving block 502 toward the fixing block 401, so that the adjusting slide rod 503 drives the sliding blocks 605 to move closer to each other, Cover the display board 7 on one side of the installation frame 3 so that the U-shaped block 701 corresponds to the clamping protrusion 606, then release the movable block 502. Under the elastic action of the clamping spring 607, the sliding block 605 drives the clamping protrusion 606 to move to both sides to ensure that the clamping protrusion 606 is clamped into the corresponding fixed slot 702. Screw the adjusting screw sleeve 504 to fit the movable block 502, clamp and fix the movable block 502, and ensure that the two sets of relative sliding blocks 605 will not approach each other, causing the clamping protrusion 606 to disengage from the fixed slot 702.

[0031] In the description of the present invention, it should be noted that, unless otherwise clearly specified and limited, the terms "installation", "connection" and "connection" should be understood in a broad sense, for example, it can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection, or it can be an indirect connection through an intermediate medium, or it can be the internal communication of two components. For ordinary technicians in this field, the specific meanings of the above terms in the present invention can be understood by specific circumstances.

[0032] The above describes in detail the preferred implementation of this patent, but this patent is not limited to the above implementation. Various changes can be made within the knowledge scope of ordinary technicians in this field without departing from the purpose of this patent.
