Description

Technical Field

[0001] This invention belongs to the technical field of office supplies auxiliary equipment, and relates to a display rack fixing structure. Background Technology

[0002] Currently, before construction begins, a comprehensive discussion of the overall project plan and construction cost is required. Therefore, when holding seminars on project costs, display devices are often used to present the discussion content for public discussion. Traditional display devices mostly utilize projection equipment to project materials onto a corresponding display screen.

[0003] As disclosed in application publication number CN 108389526 A, a conference display board mounting bracket has a mounting base fixed on the bracket, and an auxiliary plate fixed on the upper side of the mounting base. A fitting gap exists between the base and the auxiliary plate, and a front clamping member and a rear clamping member are inserted within the fitting gap. Each clamping member includes a connecting plate and a movable wall plate. Active cone plates are respectively provided at the inner ends of the front and rear connecting plates; passive cone plates on both sides engage with the inclined surfaces of the front and rear active cone plates; a tension spring connects the rear connecting plate and the front connecting plate; a support plate is provided in the middle of the pressing column, and a spring is connected between the support plate and the inner surface of the base. This invention allows a black and white display board to be directly pressed against the inside of the junction box. Utilizing the pressing action of the black and white display board, the pressing column is driven to move downwards, thereby causing the support plate to disengage from the front and rear connecting plates. Under the action of the tension spring, the front and rear connecting plates instantly retract inwards. This operation is very simple and can be completed in one step.

[0004] However, in the above solution, when the staff fixes the conference display board to the fixed frame, the height of the conference display board is determined by the fixed support frame at the bottom of the display board, and its height is fixed. When the height of the conference display board needs to be adjusted, the fixed support frame needs to be replaced, which takes a long time to adjust. Summary of the Invention

[0005] The purpose of this invention is to address the aforementioned problems in existing technologies by proposing a display rack fixing structure.

[0006] The objective of this invention can be achieved through the following technical solution: a display rack fixing structure, including a base, on which a fixed mounting frame and a movable mounting box are symmetrically arranged, and a display panel is arranged between the fixed mounting frame and the movable mounting box. The movable mounting box is provided with a lifting component for driving the display panel to rise and fall. The fixed mounting plate is provided with an auxiliary sliding component. The display panel can slide horizontally on the base. The base is provided with an adjustment component for driving the movable mounting box to move toward the fixed mounting frame. The lifting component includes a plurality of rollers arranged along the movable mounting box and a linkage drive component for synchronously driving all rollers to rotate.

[0007] In the above-mentioned display rack fixing structure, the roller component includes a rotating shaft rotatably connected to the inner cavity of the movable mounting box and elastic clamping wheels disposed at both ends of the rotating shaft. The wheel surface of the elastic clamping wheel is located outside the mounting frame. The movable mounting box is provided with a through hole, and the elastic clamping wheel passes through the through hole.

[0008] In the aforementioned display rack fixing structure, the linkage drive assembly includes a rotating shaft vertically rotatably connected to the inner cavity of the movable mounting box. The rotating shaft is equipped with several first bevel gears, and each rotating shaft has a second bevel gear meshing with the first bevel gears. A drive motor for driving the rotating shaft is located at the top of the movable mounting box. When the drive motor is started, its output rotates, causing the rotating shaft to rotate. This rotation of the rotating shaft causes the first bevel gears on the rotating shaft to rotate. The first bevel gears mesh with the second bevel gears, thereby causing the second bevel gears to rotate. When the elastic clamping wheel clamps the display panel, the friction between the elastic clamping wheel and the display panel can cause the display panel to rise and fall.

[0009] In the above-mentioned display rack fixing structure, there are two fixing brackets, which are respectively located on both sides of the base. The fixing bracket has a through groove on the side closer to the display board. The auxiliary sliding component includes several auxiliary rollers rotatably connected in the through groove. One end of the auxiliary roller is located outside the through groove, and the auxiliary rollers are distributed along the length of the through groove.

[0010] In the aforementioned display rack fixing structure, the adjustment component includes symmetrically arranged sliding frames on the base. The sliding frames are T-shaped and located on both sides of the movable mounting box. The movable mounting box is equipped with a fixed rod, and the fixed rod has a slider. The top of each sliding frame has a groove for mounting the slider. Connecting rods are located at the ends of the two sliding frames, and driving cylinders for adjusting the position of the movable mounting box are mounted on the connecting rods. The output end of the driving cylinder is connected to the movable mounting box, enabling it to slide horizontally, thereby adjusting the distance between the movable mounting box and the fixed mounting frame. This allows the fixing structure to fix display panels of different thicknesses.

[0011] In the aforementioned display rack fixing structure, limiting grooves are formed on both sides of the display panel. When the movable mounting box and the fixed mounting bracket clamp the display panel, the other side of the elastic clamping wheel and the auxiliary roller are located within the limiting grooves. The limiting grooves prevent the display panel from shifting during the up-and-down sliding process.

[0012] In the aforementioned display rack fixing structure, an arc-shaped groove is provided in the limiting groove near the elastic clamping wheel. When the display panel is fixed, the elastic clamping wheel is located within the arc-shaped groove. The arc-shaped groove allows the display panel to position the elastic clamping wheel after it is fixed. When the display panel is adjusted, the elastic clamping wheel is compressed and contracts, thereby increasing the friction between it and the display panel, making it easier to adjust the display panel. After adjustment, the arc-shaped groove recesses inward, providing a return space for the elastic clamping wheel, allowing it to lock into the arc-shaped groove, thus achieving a positioning effect.

[0013] In the aforementioned display rack fixing structure, the bottom of the display panel is equipped with several sliding wheels arranged along the length of the bottom groove. The sliding wheels allow the display panel to move on the ground, facilitating its handling by staff.

[0014] Compared with the prior art, the present invention sets up a fixed mounting frame, a movable mounting box, a display board, a lifting component, an adjustment component, and a linkage drive component. The adjustment component is used to adjust the distance between the movable mounting box and the fixed mounting frame, thereby clamping the display board between the fixed mounting frame and the movable mounting box. After clamping, the lifting component can adjust the height of the display board. When the staff needs to adjust the height of the display board, the drive motor is started. The output end of the drive motor rotates, which drives the rotating shaft to rotate. The rotation of the rotating shaft drives the first bevel gear on the rotating shaft to rotate. The first bevel gear meshes with the second bevel gear, thereby driving the second bevel gear to rotate. The rotation of the second bevel gear drives the rotating shaft and the elastic clamping wheels at both ends of the rotating shaft to rotate. Thus, the friction between the elastic clamping wheels and the display board drives the display board to rise and fall. Attached Figure Description

Detailed Implementation

[0018] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0019] Example

[0020] like Figure 1 and Figure 2 As shown, a display rack fixing structure includes a base 1. A fixed mounting bracket 2 and a movable mounting box 3 are symmetrically arranged on the base 1. A display panel 4 is positioned between the fixed mounting bracket 2 and the movable mounting box 3. Limiting grooves 8 are formed on both sides of the display panel 4. When the movable mounting box 3 and the fixed mounting bracket 2 clamp the display panel 4, the other side of the elastic clamping wheel 512 and the auxiliary roller 61 are located within the limiting grooves 8. The limiting grooves 8 prevent the display panel 4 from shifting during its vertical sliding process.

[0021] An arc-shaped groove 9 is provided in the limiting groove 8 near the elastic clamping wheel 512. When the display panel 4 is fixed, the elastic clamping wheel 512 is located in the arc-shaped groove 9. The arc-shaped groove 9 allows the display panel 4 to position the elastic clamping wheel 512 after it is fixed. When the display panel 4 is adjusted, the elastic clamping wheel 512 is compressed and contracted, thereby increasing the friction between it and the display panel 4, making it easier to adjust the display panel 4. After adjustment, the arc-shaped groove 9 is recessed inward, allowing the elastic clamping wheel 512 to have a return space, so that the elastic clamping wheel 512 can be locked in the arc-shaped groove 9, thereby achieving a positioning effect.

[0022] The fixed mounting plate is provided with an auxiliary sliding component 6. There are two fixed mounting brackets 2, which are respectively located on both sides of the base 1. The fixed mounting bracket 2 has a through groove 11 on the side near the display plate 4. The auxiliary sliding component 6 includes a plurality of auxiliary rollers 61 rotatably connected in the through groove 11. One end of the auxiliary rollers 61 is located outside the through groove 11. The auxiliary rollers 61 are distributed along the length of the through groove 11.

[0023] The installation box 3 is equipped with a lifting assembly 5 for driving the display panel 4 to rise and fall.

[0024] The lifting assembly 5 includes a plurality of rollers 51 arranged along the movable mounting box 3 and a linkage drive assembly 53 for synchronously driving all rollers 51 to rotate.

[0025] The roller assembly 51 includes a rotating shaft 511 rotatably connected to the inner cavity of the movable mounting box 3 and elastic clamping wheels 512 disposed at both ends of the rotating shaft 511. The wheel surface of the elastic clamping wheel 512 is located outside the mounting frame. The movable mounting box 3 is provided with a through hole 52, and part of the elastic clamping wheel 512 passes through the through hole 52.

[0026] The linkage drive assembly 53 includes a rotating shaft 531 vertically rotatably connected to the inner cavity of the movable mounting box 3. Several first bevel gears 532 (not shown in the figure) are mounted on the rotating shaft 531. Each rotating shaft 511 is equipped with a second bevel gear 533 meshing with the first bevel gears 532. A drive motor 534 for driving the rotating shaft 531 to rotate is mounted on the top of the movable mounting box 3. When the drive motor 534 is started, its output end rotates, causing the rotating shaft 531 to rotate. The rotation of the rotating shaft 531 causes the first bevel gears 532 on the rotating shaft 531 to rotate. The first bevel gears 532 mesh with the second bevel gears 533, thereby driving the second bevel gears 533 to rotate. When the elastic clamping wheel 512 clamps the display panel 4, the friction between the elastic clamping wheel 512 and the display panel 4 can drive the display panel 4 to rise and fall.

[0027] The display panel 4 can slide horizontally on the base 1. The base 1 is equipped with an adjustment assembly 7 that drives the movable mounting box 3 to move towards the fixed mounting frame 2. The adjustment assembly 7 includes symmetrically arranged sliding frames 71 on the base 1. The sliding frames 71 are T-shaped and located on both sides of the movable mounting box 3. The movable mounting box 3 is equipped with a fixing rod 72, and a slider 73 is mounted on the fixing rod 72. The top of the sliding frame 71 has a groove 74 for mounting the slider 73. Connecting rods 75 are located at the ends of the two sliding frames 71. A drive cylinder 76 for adjusting the position of the movable mounting box 3 is mounted on the connecting rod 75. The output end of the drive cylinder 76 is connected to the movable mounting box 3, enabling it to slide horizontally, thereby adjusting the distance between the movable mounting box 3 and the fixed mounting frame 2. This allows the fixing structure to fix display panels 4 of different thicknesses.

[0028] The display panel 4 is provided with several sliding wheels 10 arranged along the length of the bottom groove. The sliding wheels allow the display panel 4 to move on the ground, making it convenient for staff to move it.

[0029] This invention comprises a fixed mounting frame 2, a movable mounting box 3, a display panel 4, a lifting assembly 5, an adjustment assembly 7, and a linkage drive assembly 53. The adjustment assembly 7 is used to adjust the distance between the movable mounting box 3 and the fixed mounting frame, thereby clamping the display panel 4 between the fixed mounting frame 2 and the movable mounting box 3. After clamping, the lifting assembly 5 can adjust the height of the display panel 4. When the staff needs to adjust the height of the display panel 4, the drive motor 534 is started. The output end of the drive motor 534 rotates, driving the rotating shaft 531 to rotate. The rotation of the rotating shaft 531 drives the first bevel gear 532 on the rotating shaft 531 to rotate. The first bevel gear 532 meshes with the second bevel gear 533, thereby driving the second bevel gear 533 to rotate. The rotation of the second bevel gear 533 drives the rotating shaft 511 and the elastic clamping wheels 512 at both ends of the rotating shaft 511 to rotate, thereby driving the display panel 4 to rise and fall through the friction between the elastic clamping wheels 512 and the display panel 4.
