Description

Technical Field

[0001] This utility model relates to the field of mounting bracket technology, specifically a guide rail structure and a billboard mounting bracket. Background Technology

[0002] Billboards refer to all outdoor media that convey advertising information. The size of the media depends on the actual environment. The images on shop signs, storefronts, and facades can be hand-drawn, computer-generated, or printed on paper. The materials for billboards are generally welded together from square tubing, angle iron, etc.

[0003] In the prior art, CN221327330U discloses a guide rail structure and a billboard mounting bracket. Although the above-mentioned prior art enables the installation of billboards, in actual use, the billboard needs to be hung on a screw rod first. At this time, the screw rod will mainly bear the weight of the billboard itself. When the weight of the billboard is large, the local structure is prone to deformation due to stress concentration. Then, the billboard is fixed by the first bolt. After long-term use, the screw rod will wear, which will cause the fixing of the billboard to loosen. Over time, this wear of the screw rod will increase, causing the connection between the screw rod and the first bolt to weaken. Failure of the connection reduces the service life and stability of the structure, thus affecting the installation quality of the billboard. It may even lead to safety accidents such as the billboard falling due to insecure installation. Furthermore, the steps of disassembly, installation, adjustment, and locking also require a lot of time to complete the installation of the billboard. For scenarios that require frequent replacement of billboards, such as shopping malls and exhibitions, excessive disassembly and assembly time will seriously affect the operational efficiency of the site and increase labor costs. In outdoor installation or maintenance operations, the cumbersome disassembly and assembly process will prolong the working time of operators at heights or in complex environments, increasing safety hazards. It has poor practicality and flexibility. In view of this, we propose a guide rail structure and a billboard mounting bracket to solve the above problems. Utility Model Content

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model. Example 1:

[0019] Please see Figures 1-8 This utility model provides a technical solution: a billboard mounting bracket, including a mounting block 1, a mounting groove 2 on the lower surface of the mounting block 1, two sliding grooves 3 inside the mounting block 1, sliding blocks 4 slidably connected inside the two sliding grooves 3, and locking blocks 5 slidably connected inside the sliding blocks 4, a horizontal cavity 6 and a vertical cavity 7 inside the mounting block 1, the horizontal cavity 6 and the vertical cavity 7 are connected, the vertical cavity 7 is connected to the two sliding grooves 3, two moving plates 8 are slidably connected inside the vertical cavity 7, a transmission gear 9 is provided between the two moving plates 8, the transmission gear 9 is rotatably connected inside the vertical cavity 7 via a shaft, a toothed groove 10 is provided on the adjacent side surface of the two moving plates 8, the toothed groove 10 is meshed with the transmission gear 9, a fixing plate 11 is fixedly connected to the surface of the two moving plates 8, the two fixing plates 11 are respectively fixedly connected to the two sliding blocks 4, an operating rod 12 is rotatably connected to the surface of the right fixing plate 11, the operating rod 12 moves through the interior of the mounting block 1, and an adjustment component is provided inside the horizontal cavity 6.

[0020] The lower side of the mounting block 1 is also provided with an advertising board that is compatible with the mounting slot 2, and the surface of the advertising board is also provided with a slot that is compatible with the card block 5.

[0021] A first compression spring 13 is fixedly connected between the inner walls of the locking block 5 and the sliding block 4. The first compression spring 13 facilitates the reset of the locking block 5 and ensures that the locking block 5 is always located in the slot opened on the surface of the billboard. Since the length of the locking block 5 inside the slot on the surface of the billboard is relatively long, it will not disengage from the slot inside the billboard when the locking block 5 vibrates. A second compression spring 14 is fixedly connected between each of the two sliding blocks 4 and the inner walls of the two sliding grooves 3. The second compression spring 14 facilitates the reset of the sliding blocks 4. A third reset spring 15 is fixedly connected between the inner wall of the rear moving plate 8 and the vertical cavity 7 through a connecting plate. The third reset spring 15 facilitates the reset of the rear moving plate 8, thereby driving the transmission gear 9 to rotate, and thus realizing the synchronous reset of the front moving plate 8.

[0022] The adjustment assembly includes a mounting shaft 16, which is rotatably connected inside the transverse cavity 6. Two abutment members 17 are provided on the outside of the mounting shaft 16. A bidirectional threaded rod 18 is rotatably connected to the inner wall of the transverse cavity 6. The two abutment members 17 are respectively threaded onto two opposite threads of the bidirectional threaded rod 18. The two abutment members 17 can move inside the transverse cavity 6 by rotating the bidirectional threaded rod 18.

[0023] In the above embodiments, a friction layer is provided on the side surface of the abutment 17 facing the mounting shaft 16 and the surface of the mounting shaft 16. The working principle between the abutment 17 and the mounting shaft 16 is similar to that of a brake pad. Since this is a conventional technical means in the field, it will not be described in detail here.

[0024] Both the operating lever 12 and the bidirectional threaded rod 18 are equipped with synchronous pulleys 19. The surface of the operating lever 12 is provided with a keyway 20. The lower synchronous pulley 19 is slidably sleeved on the outside of the operating lever 12 through the keyway 20. The lower synchronous pulley 19 is rotatably connected to the inner wall of the vertical cavity 7 through a mounting ring. The upper synchronous pulley 19 is fixedly sleeved on the outside of the bidirectional threaded rod 18. The two synchronous pulleys 19 are meshed with a toothed belt 21.

[0025] When the operator rotates the operating lever 12, since the operating lever 12 and the rear fixed plate 11 are rotatably connected, the fixed plate 11 will not move. However, because the lower synchronous pulley 19 is slidably sleeved on the outside of the operating lever 12 via the keyway 20, the operating lever 12 will drive the lower synchronous pulley 19 to rotate. At this time, under the transmission of the toothed belt 21, the upper bidirectional threaded rod 18 will rotate. Additionally, when the operator pulls the operating lever 12, the operating lever 12 will slide inside the lower synchronous pulley 19. At this time, the synchronous pulley 19 will not move under the support of the mounting ring. The operating lever 12 can then drive the movement of the right fixed plate 11, thereby driving the rear fixed plate 18 to move. The movement of the movable plate 8 drives the rotation of the transmission gear 9 through the movement of the rear movable plate 8, which in turn drives the front movable plate 8 to move. Finally, under the action of the two fixed plates 11, the two sliding blocks 4 will slide inside the sliding groove 3 until the locking block 5 disengages from the slot opened on the surface of the billboard. The billboard can then be disassembled. During installation, the billboard is directly inserted into the installation groove 2 so that the billboard and the inclined surface of the locking block 5 come into contact. At this time, the locking block 5 will move inside the sliding block 4, and the first compression spring 13 will also produce elastic deformation. Subsequently, the locking block 5 can be locked into the slot on the surface of the billboard by means of the elastic force of the first compression spring 13.

[0026] Example 2: Based on Example 1: A guide rail structure includes a guide rail body 22. A T-shaped groove 23 extending from the lower surface is provided inside the guide rail body 22. A T-shaped movable seat 24 is slidably connected inside the T-shaped groove 23. The upper end of a mounting shaft 16 rotatably passes through the interior of a mounting block 1. The upper end of the mounting shaft 16 is fixedly connected to the lower surface of the T-shaped movable seat 24. When two clamping members 17 are in close contact with the mounting shaft 16, the mounting block 1 will not rotate outside the mounting shaft 16 because the mounting shaft 16 and the T-shaped movable seat 24 are fixed. When the two clamping members 17 no longer clamp the mounting shaft 16, the mounting block 1 can then rotate outside the mounting shaft 16, thereby adjusting the mounting angle.

[0027] The T-shaped slide 23 has a guide block 25 slidably connected inside. The T-shaped moving seat 24 and the guide block 25 are fixedly connected. The T-shaped slide 23 has an adjusting screw 26 rotatably connected inside. The guide block 25 is threadedly connected to the outside of the adjusting screw 26. By rotating the adjusting screw 26, the guide block 25 can be driven to slide inside the T-shaped slide 23, thereby realizing stepless adjustment of the billboard installation position.

[0028] A motor 27 is fixedly connected to the surface of the guide rail body 22. The output shaft of the motor 27 rotates through the interior of the guide rail body 22. The output shaft of the motor 27 is fixedly connected to the adjusting screw 26 through a coupling. The adjusting screw 26 can be rotated by starting the motor 27.

[0029] Among them, the motor 27 is also equipped with a power supply, wires, controller and microcomputer, etc. Since they are not the main structures, they will not be described in detail in this article.

[0030] Two pulleys 28 are embedded on the lower surface of the guide block 25. The pulleys 28 are in contact with the inner wall of the T-shaped groove 23. The pulleys 28 further ensure the stability and smoothness of the guide block 25 sliding inside the T-shaped groove 23, effectively reduce the friction between structures, and extend the service life of the device.

[0031] Working principle: When using this guide rail structure and billboard mounting bracket, the operator inserts the billboard to be installed into the mounting slot 2. At this time, the billboard will contact the inclined surface of the locking block 5, causing the locking block 5 to move inside the sliding block 4. The first compression spring 13 will also undergo elastic deformation. Subsequently, the locking block 5 can be locked into the slot on the surface of the billboard by the elastic force of the first compression spring 13 itself. When it is necessary to adjust the installation angle of the billboard, the operating rod 12 is rotated. Since the operating rod 12 is rotatably connected to the rear fixing plate 11, it will not cause the fixing plate 11 to move. Also, because the lower synchronous wheel 19 slides through the keyway 20... Located outside the operating lever 12, the operating lever 12 drives the lower synchronous pulley 19 to rotate. At this time, under the transmission of the toothed belt 21, the upper double-threaded rod 18 will rotate. Through the rotation of the double-threaded rod 18, the two clamping parts 17 can move inside the transverse cavity 6. When the two clamping parts 17 are in close contact with the mounting shaft 16, since the mounting shaft 16 and the T-shaped moving seat 24 are fixed, the mounting block 1 will not rotate outside the mounting shaft 16. When the two clamping parts 17 no longer clamp the mounting shaft 16, the mounting block 1 can then rotate outside the mounting shaft 16, thereby realizing the adjustment and locking of the mounting angle.

[0032] When the billboard needs to be dismantled, the operating lever 12 is pulled. When the operator pulls the operating lever 12, the operating lever 12 will slide inside the lower synchronous wheel 19. At this time, the synchronous wheel 19 will not move under the support of the mounting ring. The operating lever 12 can drive the right fixed plate 11 to move, which in turn drives the rear moving plate 8 to move. The movement of the rear moving plate 8 can drive the rotation of the transmission gear 9, which in turn drives the front moving plate 8 to move. Finally, under the action of the two fixed plates 11, the two sliding blocks 4 will slide inside the sliding groove 3 until the locking block 5 disengages from the locking groove opened on the surface of the billboard, and then the billboard can be dismantled.

[0033] When the installation position of the billboard needs to be adjusted, the motor 27 is started to drive the adjustment screw 26 to rotate. The rotation of the adjustment screw 26 drives the guide block 25 to slide inside the T-shaped slide groove 23, thereby realizing stepless adjustment of the billboard installation position.

[0034] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
