[0007] By adopting the above technical solution, when installing the display box, according to actual needs, after adjusting the X-axis adjustment member, the Y-axis adjustment member and the Z-axis adjustment member to a suitable posture, the display box is installed on the Z-axis adjustment member to reduce the installation error of the display box. After the display box is installed on the Z-axis adjustment member, according to the posture of the adjacent display box, the display box is fine-tuned again along the X-axis direction, the Y-axis direction and / or the Z-axis direction through the X-axis adjustment member, the Y-axis adjustment member and the Z-axis adjustment member, so as to adjust the installation posture of the display box, which is conducive to reducing the installation error of the display box.

[0011] By adopting the above technical solution, when adjusting the display box along the Y-axis direction, the display box is held and the Y-axis adjustment screw is rotated, so that the first adjustment rod and the second adjustment rod can move in a direction close to or away from each other, thereby moving the display box along the Y-axis direction and locking it to a desired position, which is convenient and reliable.

[0012] Optionally, the Z-axis adjustment member includes a fixed adjustment plate, a sliding adjustment plate and a Z-axis locking bolt; The fixed adjustment plate is used to connect the Z-axis adjustment member to the Y-axis adjustment member. The fixed adjustment plate is provided with a Z-axis adjustment slot extending along the Z-axis direction. The Z-axis locking bolt is used to connect the fixed adjustment plate and the sliding adjustment plate. The Z-axis locking bolt is passed through the Z-axis adjustment slot.

[0013] By adopting the above technical solution, when adjusting the display box along the Z-axis direction, the Z-axis locking bolt can be loosened to lift or press down the Z-axis adjustment member and the display box, so that the display box is moved to the desired position along the Z-axis direction. After the display box is moved to the desired position along the Z-axis direction, the Z-axis locking bolt can be tightened to fix the Z-axis adjustment member and the display box to the Y-axis adjustment member, thereby locking the display box at the desired position, which is convenient and reliable.

[0014] Optionally, the first adjustment plate is installed with a first rubber pad, the first rubber pad faces the second adjustment plate, and the second adjustment plate is installed with a second rubber pad, the second rubber pad faces the first adjustment plate.

[0015] By adopting the above technical solution, the first adjustment plate is tightly fitted to the adjustment rail through the first rubber pad, and the second adjustment plate is tightly fitted to the adjustment rail through the second rubber pad, which is beneficial to increase the friction between the X-axis adjustment member and the adjustment rail, thereby ensuring the position stability of the display box.

[0017] By adopting the above technical solution, multiple X-axis locking bolts are conducive to increasing the connection stability between the X-axis adjustment member and the adjustment slide rail. In addition, by locking the drive assembly, each X-axis locking bolt can be synchronously driven to rotate, which is conducive to reducing the situation where operators frequently turn multiple X-axis locking bolts, thereby improving the efficiency of operators' disassembly and assembly, and facilitating the flow of display screens between various activity occasions.

[0018] Optionally, the locking drive member includes a driven synchronous wheel, a driving synchronous wheel and a driving synchronous belt; There are several driven synchronous wheels, and the driven synchronous wheels are respectively installed on each X-axis locking bolt. The active synchronous wheel is rotationally matched with the first adjustment plate. The driving synchronous belt is wound around the active synchronous wheel and each driven synchronous wheel. The active synchronous wheel and each driven synchronous wheel are frictionally matched with the driving synchronous belt.

[0019] By adopting the above technical solution, the driving synchronous belt drives the active synchronous wheel and each driven synchronous wheel to rotate through friction, which is conducive to ensuring that each X-axis locking bolt rotates at the same time and reducing the occurrence of individual X-axis locking bolts getting stuck and locked.

[0021] By adopting the above technical solution, when the driving synchronous belt slips significantly, the sliding wheel block is moved away from the axis of the fixed wheel disc in the radial direction of the fixed wheel disc through the tensioning driving member, thereby increasing the diameter of the active synchronous wheel and tensioning the driving synchronous belt, thereby reducing the slip of the driving synchronous belt and ensuring that the X-axis locking bolts can rotate synchronously for a long time, and the structure is relatively compact.

[0023] By adopting the above technical solution, when it is necessary to move the sliding wheel block away from the axis of the fixed wheel disc in the radial direction of the fixed wheel disc, the tensioning knob is turned to make the tensioning abutment block move toward the tensioning inclined surface, and then the sliding wheel block is extended from the fixed wheel disc under the action of the tensioning inclined surface, thereby tensioning the driving synchronous belt, and the structure is relatively compact.

[0024] Optionally, the first adjustment plate is provided with a protective cover, and the protective cover is provided on the first adjustment plate and the locking drive assembly.

[0025] The adoption of the above technical solution is helpful to reduce the situation where the accuracy of the locking drive component is reduced due to dust.

[0043] When the X-axis adjustment member 2 needs to slide along the X-axis direction, the four X-axis locking bolts 23 are loosened to move the first adjustment plate 21 and the second adjustment plate 22 away from the adjustment rail 1, so that the X-axis adjustment member 2 slides and fits on the adjustment rail 1. When the position of the X-axis adjustment member 2 needs to be locked, the four X-axis locking bolts 23 are tightened to make the first adjustment plate 21 and the second adjustment plate 22 respectively fit tightly on both sides of the adjustment rail 1 along the Y-axis direction, so that the X-axis adjustment member 2 is firmly locked at the specified position of the adjustment rail 1.

The first adjustment rod 31, the second adjustment rod 32 and the Y-axis adjustment screw 33 are all arranged along the Y-axis direction, and the first adjustment rod 31 is fixedly connected to the first adjustment plate 21. A threaded chamber (not shown in the figure) is provided inside the Y-axis adjustment screw 33, and the threads at both ends of the threaded chamber have opposite rotation directions, that is, the threads at both ends of the threaded chamber are clockwise and counterclockwise, respectively. The first adjustment rod 31 and the second adjustment rod 32 are respectively threadedly engaged with the two ends of the threaded chamber, so that the first adjustment rod 31 and the second adjustment rod 32 can move in a direction closer to or farther away from each other by rotating the Y-axis adjustment screw 33, so that the Y-axis adjustment member 3 can be extended and retracted along the Y-axis direction.

There are two Z-axis locking bolts 43, and the two Z-axis locking bolts 43 are respectively arranged corresponding to each Z-axis adjustment slot 411. The Z-axis locking bolt 43 is used to connect the fixed adjustment plate 41 and the sliding adjustment plate 42, and specifically in this embodiment, the Z-axis locking bolt 43 is penetrated through the Z-axis adjustment slot 411, and the fixed adjustment plate 41 and the sliding adjustment plate 42 are connected by a nut that is tightly fitted on the sliding adjustment plate 42. The sliding adjustment plate 42 is provided with four mounting through holes, and the four mounting through holes are distributed in a rectangular shape, so that the display box can be installed on the sliding adjustment plate 42 through the mounting through holes.

[0046] The implementation principle of a multi-directional adjustment bracket in Example 1 of the present application is: when installing the display box, according to actual needs, the X-axis locking bolt 23 of the X-axis adjustment member 2, the Y-axis adjustment screw 33 of the Y-axis adjustment member 3 and the Z-axis locking bolt 43 of the Z-axis adjustment member 4 are rotated to adjust the multi-directional adjustment bracket to a suitable posture, and then the display box is installed on the Z-axis adjustment member 4 to reduce the installation error of the display box.

[0047] After the display box is installed on the Z-axis adjustment member 4, the display box is fine-tuned again along the X-axis direction, the Y-axis direction and / or the Z-axis direction through the X-axis adjustment member 2, the Y-axis adjustment member 3 and the Z-axis adjustment member 4 according to the posture of the adjacent display box, so as to adjust the installation posture of the display box, which is beneficial to reduce the installation error of the display box.

[0048] Embodiment 2: The embodiment of the present application discloses an X-axis adjusting member 2, which is used for the multi-directional adjusting bracket described in Embodiment 1. The main difference between the X-axis adjusting member 2 described in Embodiment 1 and the X-axis adjusting member 2 described in Embodiment 1 is that: Reference Figure 4 and Figure 5 The X-axis adjustment member 2 includes a first adjustment plate 21, a second adjustment plate 22 and an X-axis locking bolt 23. The first adjustment plate 21 and the second adjustment plate 22 are both arranged in a square shape, and are respectively located on both sides of the adjustment slide rail 1, and the first adjustment plate 21 and the second adjustment plate 22 are distributed along the Y-axis direction, and the second adjustment plate 22 is slidably matched with the first adjustment plate 21 along the Y-axis direction through two guide plates.

[0049] Four X-axis locking bolts 23 are provided, and the four X-axis locking bolts 23 are respectively located at the four corners of the first adjustment plate 21. One end of the X-axis locking bolt 23 is rotatably engaged with the first adjustment plate 21, and the other end of the X-axis locking bolt 23 is threadedly engaged with the second adjustment plate 22, so that the second adjustment plate 22 is moved closer to or away from the first adjustment plate 21 by rotating the X-axis locking bolt 23.

[0050] The first adjustment plate 21 is provided with a locking drive assembly 5, and the locking drive member includes a driven synchronous wheel 51, a driving synchronous wheel 52 and a driving synchronous belt 53. There are four driven synchronous wheels 51, and the four driven synchronous wheels 51 are coaxially fixedly installed on each X-axis locking bolt 23. The driving synchronous wheel 52 is rotationally matched with the first adjustment plate 21, and the driving synchronous wheel 52 is arranged near the center of the first adjustment plate 21. The driving synchronous belt 53 is wound around the driving synchronous wheel 52 and each driven synchronous wheel 51, and the driving synchronous wheel 52 and each driven synchronous wheel 51 are frictionally matched with the driving synchronous belt 53, so as to ensure that the driving synchronous wheel 52, the driven synchronous wheel 51 and the driving synchronous belt 53 respond and move in time. In addition, the driving synchronous wheel 52 close to the center of the first adjustment plate 21 is conducive to reducing the volume on the one hand, and on the other hand, it is also conducive to further increasing the contact area between the driving synchronous belt 53 and the driving synchronous wheel 52 and the driven synchronous wheel 51, so that the driving synchronous wheel 52 of the locking drive member drives each X-axis locking bolt 23 to rotate synchronously.

[0051] The first adjustment plate 21 is provided with a protective cover 211, which is provided on the first adjustment plate 21 and the locking drive assembly 5, so that dust is not easy to affect the locking drive. The active synchronous wheel 52 is coaxially fixedly installed with a locking knob 54, which is located outside the protective cover 211, so that the operator can drive the active synchronous wheel 52 to rotate.

[0052] In addition, the first adjustment plate 21 is fixedly mounted with a first rubber pad 212, and the first rubber pad 212 faces the second adjustment plate 22. The second adjustment plate 22 is fixedly mounted with a second rubber pad 221, and the second rubber pad 221 faces the first adjustment plate 21, so that the first adjustment plate 21 is tightly fitted to the adjustment rail 1 through the first rubber pad 212, and the second adjustment plate 22 is tightly fitted to the adjustment rail 1 through the second rubber pad 221, thereby increasing the friction between the X-axis adjustment member 2 and the adjustment rail 1, thereby ensuring the position stability of the display box.

[0053] The implementation principle of an X-axis adjustment member 2 in Example 2 of the present application is: by locking the drive assembly 5, each X-axis locking bolt 23 is synchronously driven to rotate, which is beneficial to reduce the occurrence of operators frequently turning multiple X-axis locking bolts 23, thereby improving the efficiency of operators' disassembly and assembly, and facilitating the flow of display screens between various activity occasions.

The fixed wheel disc 521 is arranged in a circular shape, and a wheel disc slot is provided inside the fixed wheel disc 521. There are four sliding wheel blocks 522, and the four sliding wheel blocks 522 are all located in the wheel disc slot, and the four sliding wheel blocks 522 are arranged in a fan shape. Four limiting sliders 5211 are fixedly connected inside the wheel disc slot, and the four limiting sliders 5211 are axially distributed around the axis of the fixed wheel disc 521 and the four limiting sliders 5211 extend radially along the fixed wheel disc 521. The sliding wheel block 522 is provided with a wheel block slot 5221, and the sliding wheel block 522 is slidably matched with the limiting slider 5211 through the wheel block slot 5221, so that the sliding wheel block 522 can slide along the radial direction of the fixed wheel disc 521 and match with the wheel disc slot, so that by extending or retracting the sliding wheel block 522, the diameter of the active synchronous wheel 52 is increased or reduced with a relatively compact structure, thereby tightening or relaxing the driving synchronous belt 53 wound around the active synchronous wheel 52. In addition, four reset elastic members 523 are provided, and the four reset elastic members 523 are respectively located in the wheel block slot 5221 of each sliding wheel block 522. In this embodiment, the type of the reset elastic member 523 is a linear spring, and the two ends of the reset elastic member 523 are respectively fixedly installed on the fixed wheel disc 521 and the sliding wheel block 522, so that the sliding wheel block 522 can be reset only under the action of the reset elastic member 523.

[0055] Reference Fig. 9The sliding wheel block 522 is provided with a tensioning inclined surface 5222, which is located on one side of the sliding wheel block 522 and is inclined along the thickness direction and radial direction of the sliding wheel block 522. A tensioning driving member is provided inside the locking knob 54, and the tensioning driving member includes a tensioning knob 55 and a tensioning abutment block 56. The tensioning knob 55 is threadedly engaged with the locking knob 54, one end of the tensioning abutment block 56 is fixedly mounted on the tensioning knob 55, and the other end of the tensioning abutment block 56 faces the tensioning inclined surface 5222, so that the tensioning abutment block 56 can be brought close to the tensioning inclined surface 5222 by rotating the tensioning knob 55, and the tensioning abutment block 56 can be abutted and engaged with the tensioning inclined surface 5222, so that the sliding wheel block 522 can slide radially along the fixed wheel disc 521.

[0056] The implementation principle of an X-axis adjustment component 2 in Example 3 of the present application is: when it is necessary to move the sliding wheel block 522 away from the axis of the fixed wheel disc 521 along the radial direction of the fixed wheel disc 521, the tensioning knob 55 is rotated to make the tensioning abutment block 56 move toward the tensioning inclined surface 5222, and then the sliding wheel block 522 is extended from the fixed wheel disc 521 under the action of the tensioning inclined surface 5222, thereby tensioning the driving synchronous belt 53, and the structure is relatively compact.

[0057] The above are all preferred embodiments of the present application, and the protection scope of the present application is not limited thereto. Therefore, any equivalent changes made according to the structure, shape, and principle of the present application should be included in the protection scope of the present application.
