Description

Technical Field

[0001] This utility model relates to the field of advertising signage technology, and in particular to a modular large-scale advertising signage device. Background Technology

[0002] Signage advertising refers to advertising that uses the image and content of a sign as its basic form. Signboards refer to signs designed for visual effect and are called panel signs. Existing large advertising signs are generally welded as a single piece. When it is necessary to replace the advertisement later, a relatively long replacement operation needs to be carried out at a height. Working at height is not only relatively slow, but also has a greater risk factor.

[0003] An existing patent (publication number: CN218100620U) discloses a modular large advertising sign device. This modular large advertising sign device includes a fixed frame and an installation assembly. The installation assembly has two sets arranged within the fixed frame. Each installation assembly includes a connecting frame, a magnetic strip, a clamping frame, a guide block, and a hanging ring. When a worker operates a lifting device to remove the connecting frame from the fixed frame and place it on the ground, the worker can directly lift the clamping frame from the outer wall of the magnetic strip to replace the advertising banner. However, this technical solution still has shortcomings, specifically as follows:

[0004] The current device requires moving the lifting equipment to the vicinity before replacing the advertising banner. Then, the hooks and hanging rings must be connected to detach the mounting components from the device. The magnetic strips must then be manually removed before the banner can be replaced, making the process cumbersome. To address these issues, we propose a modular, large-scale advertising signage device. Utility Model Content

[0005] The purpose of this section is to outline some aspects of embodiments of the present invention and to briefly describe some preferred embodiments. Simplifications or omissions may be made in this section, as well as in the abstract and title of the present invention, to avoid obscuring the purpose of these documents, and such simplifications or omissions should not be construed as limiting the scope of the present invention.

[0006] Therefore, the purpose of this utility model is to provide a modular large advertising sign device that can solve the problem that existing devices require moving the lifting device to the vicinity of the device before the hook and hanging ring can be connected together to remove the installation components from the device, and then manually removing the magnetic strip before the advertising cloth can be replaced, which makes the replacement of the advertising cloth quite troublesome.

[0007] To solve the above-mentioned technical problems, this utility model provides a modular large advertising sign device, which adopts the following technical solution: it includes an adjustment mechanism, which includes two support rods, a protective shell is fixedly arranged between the two support rods, a display frame is movably inserted into the inner bottom wall of the protective shell, the two ends of the display frame pass through the protective shell and are respectively inserted into the two support rods, and a traction member is provided at the top of the protective shell, the end of the traction member passes through the protective shell and is fixedly connected to the top surface of the display frame;

[0008] The clamping mechanism includes two drive rods, which are symmetrically arranged on the front side of the display frame. Each drive rod has a clamping member threaded onto its front end. The outer walls of the two support rods are fixedly provided with toothed plates, which mesh with the drive rods.

[0009] By adopting the above technical solution, when it is necessary to replace the billboard in the display frame, the traction component is released, causing the display frame to lose its traction force. At this time, the display frame moves down continuously under the action of gravity, thereby reducing the height of the display frame. When the display frame moves down, the toothed plate drives the drive rod to rotate. As the drive rod rotates, it causes the clamping component to move and separate from the billboard in the display frame, thereby causing the billboard to lose its limit and making it easier for the operator to replace the billboard.

[0010] Optionally, the outer wall of each support rod is provided with a vertical groove, the inner wall of the vertical groove is fixedly provided with a vertical rod, and the inner bottom wall of the vertical groove is fixedly provided with a buffer ring.

[0011] By adopting the above technical solution, this solution facilitates the limitation of the end of the display frame through the cooperation of the vertical groove and the vertical rod, thereby increasing the stability of the display frame when it moves, and the display frame is cushioned by the buffer ring.

[0012] Optionally, a transparent plate is provided on the front side of the protective shell.

[0013] By adopting the above technical solution, this solution allows people to view the billboard inside the protective shell through the transparent panel.

[0014] Optionally, both ends of the display frame extend into the vertical groove and are fixedly provided with rings, which are located in the vertical groove and movably sleeved on the vertical rod.

[0015] By adopting the above technical solution, when the display frame moves, the ring moves along the inner wall of the vertical groove, and at the same time, the ring moves along the outer wall of the vertical rod.

[0016] Optionally, the traction component includes a motor, which is located on the top of the protective shell. A steel cable is wound around the rotating shaft of the motor, and the end of the steel cable away from the rotating shaft passes through the protective shell and is fixedly connected to the top surface of the display frame.

[0017] By adopting the above technical solution, this solution facilitates the release and rewinding of the steel cable by starting the motor. When the steel cable is released, the display frame loses traction and moves downward, thus making it easier for the operator to replace the billboard inside the display frame.

[0018] Optionally, the front side of the display frame is provided with an assembly groove corresponding to the drive rod, the drive rod is rotatably disposed in the assembly groove, and both ends of the display frame are provided with through grooves for the toothed plate to pass through, the through grooves being connected to the assembly groove.

[0019] By adopting the above technical solution, this solution facilitates the assembly of the drive rod through the assembly slot. When the display frame moves down, the toothed plate engages with the drive rod through the through slot, thereby controlling the movement of the clamping parts through the drive rod.

[0020] Optionally, the drive rod has an external thread, and a transmission gear corresponding to the toothed plate is fixedly sleeved on the rear end of the drive rod, and the transmission gear meshes with the toothed plate.

[0021] By adopting the above technical solution, this solution facilitates the rotation of the transmission gear through the toothed plate, and the transmission gear drives the drive rod to rotate.

[0022] Optionally, the clamping component includes a nut and a vertical plate. The nut is threaded onto the drive rod, and a limit strip is fixedly provided on the outer wall of the nut. The limit strip slides in cooperation with the inner wall of the assembly groove. The vertical plate is fixedly provided on the outer wall of the nut, and several pressure plates are fixedly provided on the side wall of the vertical plate.

[0023] By adopting the above technical solution, this solution uses a limiting strip to facilitate the limiting of the nut. As the drive rod rotates, the nut moves in the assembly slot, and the nut drives the vertical plate and pressure plate to move.

[0024] In summary, this utility model has at least one of the following beneficial effects:

[0025] The height of the display frame is continuously reduced by the release of the traction component, and the drive rod is rotated by the toothed plate. As the drive rod rotates, the clamping component moves and separates from the billboard inside the display frame, thereby causing the billboard to lose its limit and making it easier for the operator to replace the billboard.

[0026] When the traction component pulls the display frame upward, the toothed plate drives the drive rod to rotate, causing the clamping component to reset and clamp and fix the billboard, thereby fixing the billboard inside the display frame. As the display frame moves into the protective shell, the billboard can be spliced, and the billboard is more convenient to assemble. Attached Figure Description

[0033] The following is in conjunction with the appendix Figure 1-3 The present invention will be described in further detail below.

[0034] Example 1, refer to Figure 1-3 In this embodiment, to address the problem that existing devices require moving the lifting device to the vicinity of the device before connecting the hook and the hanging ring to remove the installation component from the device, and then manually removing the magnetic strip before replacing the advertising cloth, making the replacement of the advertising cloth quite cumbersome, this utility model discloses a modular large advertising sign device.

[0035] The device includes an adjustment mechanism 100, which includes two support rods 101. A protective shell 102 is fixedly installed between the two support rods 101. A display frame 103 is movably inserted into the inner bottom wall of the protective shell 102. The display frame 103 facilitates the installation of the billboard. As the display frame 103 is inserted into the protective shell 102, the billboard is assembled.

[0036] The two ends of the display frame 103 pass through the protective shell 102 and are respectively inserted into the two support rods 101. The top of the protective shell 102 is provided with a traction member 104. The end of the traction member 104 passes through the protective shell 102 and is fixedly connected to the top surface of the display frame 103. When it is necessary to replace the billboard inside the display frame 103, the traction member 104 is released, causing the display frame 103 to lose its traction force. At this time, the display frame 103 moves down continuously under the action of gravity, thereby reducing the height of the display frame 103.

[0037] The clamping mechanism 200 includes two drive rods 201, which are symmetrically arranged on the front side of the display frame 103. Each drive rod 201 has a clamping member 202 threaded onto its front end. The outer walls of the two support rods 101 are fixedly provided with toothed plates 203, which mesh with the drive rods 201. The front side of the display frame 103 has an assembly groove 103b corresponding to the drive rods 201, and the drive rods 201 are rotatably disposed in the assembly groove 103b. Both ends of the display frame 103 have through grooves 103c for the toothed plates 203 to pass through. The through grooves 103c are connected to the assembly grooves 103b, which facilitate the assembly of the drive rods 201. When the display frame 103 moves down, the toothed plates 203 mesh with the drive rods 201 through the through grooves 103c, thereby controlling the movement of the clamping members 202 through the drive rods 201.

[0038] The clamping component 202 includes a nut 202a and a vertical plate 202b. The nut 202a is threaded onto the drive rod 201. A limiting strip 202c is fixedly provided on the outer wall of the nut 202a. The limiting strip 202c slides in cooperation with the inner wall of the assembly groove 103b. The vertical plate 202b is fixedly provided on the outer wall of the nut 202a. Several pressure plates 202d are fixedly provided on the side wall of the vertical plate 202b. The limiting strip 202c facilitates the limiting of the nut 202a. As the drive rod 201 rotates, the nut 202a moves within the assembly groove 103b. The nut 202a drives the vertical plate 202b and the pressure plates 202d to move, thereby causing the pressure plates 202d to separate from the billboard, thus facilitating the operator to replace the billboard.

[0039] The drive rod 201 has an external thread, and the rear end of the drive rod 201 is fixedly fitted with a transmission gear 201a corresponding to the toothed plate 203. The transmission gear 201a meshes with the toothed plate 203, and the toothed plate 203 facilitates the rotation of the transmission gear 201a, which in turn drives the drive rod 201 to rotate.

[0040] The specific working principle is as follows: When it is necessary to replace the billboard inside the display frame 103, the traction component 104 is released, causing the display frame 103 to lose its traction force. At this time, the display frame 103 moves down continuously under the action of gravity, thereby reducing the height of the display frame 103. When the display frame 103 moves down, the toothed plate 203 drives the drive rod 201 to rotate. As the drive rod 201 rotates, it causes the clamping component 202 to move and separate from the billboard inside the display frame 103, thereby causing the billboard to lose its limit, which makes it easier for the operator to replace the billboard.

[0041] Example 2, refer to Figure 1-2 Based on the same concept as in Embodiment 1 above, this modular large-scale advertising signage device further includes:

[0042] The outer wall of the support rod 101 is provided with a vertical groove 101a. A vertical rod 101b is fixedly installed on the inner wall of the vertical groove 101a. A buffer ring 101c is fixedly installed on the inner bottom wall of the vertical groove 101a. The vertical groove 101a and the vertical rod 101b cooperate to limit the end of the display frame 103, thereby increasing the stability of the display frame 103 when it moves. The buffer ring 101c cushions the display frame 103, thereby reducing the possibility of a large impact when the display frame 103 falls rapidly.

[0043] A transparent panel 102a is provided on the front side of the protective shell 102. The transparent panel 102a allows people to view the billboard inside the protective shell 102. At the same time, the transparent panel 102a works in conjunction with the protective shell 102 to protect the billboard, thereby reducing the possibility of damage to the billboard.

[0044] The two ends of the display frame 103 extend into the vertical groove 101a and are fixedly provided with rings 103a. The rings 103a are located in the vertical groove 101a and are movably sleeved on the vertical rod 101b. When the display frame 103 moves, it drives the rings 103a to move along the inner wall of the vertical groove 101a. At the same time, the rings 103a move along the outer wall of the vertical rod 101b, thereby increasing the stability of the display frame 103 when it moves.

[0045] The specific working principle is as follows: the transparent plate 102a allows people to view the billboard inside the protective shell 102, and the transparent plate 102a works in conjunction with the protective shell 102 to protect the billboard.

[0046] When the display frame 103 moves, it drives the ring 103a to move along the inner wall of the vertical groove 101a, and at the same time the ring 103a moves along the outer wall of the vertical rod 101b, thereby increasing the stability of the display frame 103 when it moves.

[0047] The display frame 103 is cushioned by the buffer ring 101c, thereby reducing the possibility of a large impact when the display frame 103 falls rapidly.

[0048] Example 3, refer to Figure 2-3 In this embodiment, in order to solve the problem that the assembly of some existing devices is relatively troublesome, based on the same concept as in Embodiment 1 above, this modular large advertising sign device further includes:

[0049] The traction component 104 includes a motor 104a, which is located on the top of the protective shell 102. A steel cable 104b is wound around the rotating shaft of the motor 104a. One end of the steel cable 104b away from the rotating shaft of the motor 104a passes through the protective shell 102 and is fixedly connected to the top surface of the display frame 103. By starting the motor 104a, the steel cable 104b can be released and wound up. When the steel cable 104b is released, the display frame 103 loses traction and moves downward, which makes it easier for the operator to replace the billboard inside the display frame 103. When the steel cable 104b is wound up, the steel cable 104b pulls the display frame 103 to move and move to the protective shell 102, thereby realizing the assembly of the billboard.

[0050] The specific working principle is as follows: when the traction component 104 pulls the display frame 103 upward, the toothed plate 203 drives the drive rod 201 to rotate, causing the clamping component 202 to reset and clamp and fix the billboard, thereby fixing the billboard inside the display frame 103. As the display frame 103 moves into the protective shell 102, the billboard can be spliced, and the billboard is more convenient to assemble.

[0051] The above are all preferred embodiments of this utility model, and are not intended to limit the scope of protection of this utility model. Therefore, all equivalent changes made to the structure, shape and principle of this utility model should be covered within the scope of protection of this utility model.
