Description

Technical Field

[0001] The present invention relates to the technical field of advertising equipment, and in particular to a lifting and disassembling advertising light box. Background Art

[0002] There are many types of advertising light boxes. Some feature elevated display cabinets to provide a wider display area, effectively reducing obstruction from floor-level objects and enhancing the display. However, these types of advertising light boxes require workers to use a ladder to reach the cabinet height when changing display content, making operation cumbersome and posing safety risks. Therefore, there is an urgent need for advertising light boxes that can be easily disassembled and replaced with new display content. Summary of the Invention

[0003] The purpose of the present invention is to provide a lifting and disassembling advertising light box to solve one or more technical problems existing in the prior art and at least provide a beneficial choice or create conditions.

[0004] The solution of the present invention to solve its technical problems is: A lifting and disassembling advertising light box comprises: an outer shell, a bottom side of which is provided with an opening, and multiple sides of the outer shell are provided with transparent panels; a support seat, a top side of which is connected to a support column, and the support column passes upward through the opening and is connected to the inner top side of the outer shell; a lifting mechanism, comprising a lifting drive member, a base, an outer mounting frame and an inner mounting frame, the lifting drive member is provided on the support column, the lifting drive member is transmission-connected to the support seat, the lifting drive member can drive the base to cover the opening upward or open the opening downward, the inner mounting frame and the outer mounting frame are arranged on the top side of the base in a direction away from the support column, the inner mounting frame is provided with a light source assembly, and the light source assembly can emit light in the direction of the outer mounting frame.

[0005] This technical solution has at least the following beneficial effects: the outer shell is connected to the support column, and the support column is used to raise the height of the outer shell, the outer mounting frame is used to install canvas and other display contents, and the inner mounting frame located on the inner side is used to install the light source assembly. When working, the light source assembly emits light to the canvas and other display contents to achieve the effect of light display. When the canvas and other display contents need to be replaced, the lifting drive component drives the base to move downward, and drives the inner mounting frame and the outer mounting frame to move downward from the opening to the base. At this time, the canvas and other display contents are directly exposed, and the height is reduced, so they can be replaced conveniently and quickly. Then the lifting drive component is used to drive the base to move up again, so that the base covers the opening upward. In this way, the canvas and other display contents are removed and replaced from the outer shell by lifting, which greatly improves the convenience and efficiency of the entire operation process, and there is no need to use tools such as escalators to reach the working height, thereby improving the safety of operation.

[0006] As a further improvement to the above technical solution, a locking assembly is provided between the outer mounting frame, the housing, and the base, and the locking assembly can connect the outer mounting frame to the housing or the base. The locking assembly can be used to fix the outer mounting frame relative to the housing or switch it to be fixed to the base. When it is necessary to replace display content such as a canvas, the locking assembly connects the outer mounting frame to the base. At this time, moving the base downward can drive the inner mounting frame and the outer mounting frame downward together, thereby conveniently replacing the canvas and other displays on the outer mounting frame. When it is necessary to maintain the light source assembly, the locking assembly connects the outer mounting frame to the housing. At this time, moving the base downward can drive only the inner mounting frame downward, so that the light source assembly is directly exposed and can be easily maintained.

[0007] As a further improvement of the above technical solution, the locking assembly includes a transmission rod, an upper clamping block, a lower clamping block and a hanging block, the hanging block is connected to the inner top side of the outer shell, and a clamping groove is provided on one side of the hanging block, the transmission rod is rotatably connected to the outer mounting frame along the axis in the up and down directions, the top of the transmission rod extends out of the outer mounting frame and is connected to the upper clamping block, the end of the upper clamping block is formed with an upper clamping portion, the bottom end of the transmission rod passes downward through the base and is connected to the lower clamping block, and the end of the lower clamping block is formed with a lower clamping portion, and the base is provided with an avoidance hole at a position corresponding to the lower clamping portion. When the transmission rod rotates, it can drive the upper clamping portion to rotate into the clamping groove, the lower clamping portion is facing the avoidance hole, or drive the lower clamping portion to rotate out of the clamping groove, and the lower clamping portion is staggered with the avoidance hole. When it is necessary to replace the display content such as the canvas, the transmission rod is rotated so that the upper clamping part at the top of the transmission rod moves out of the clamping groove, and the lower clamping part at the top of the transmission rod is staggered with the avoidance hole, so that the outer mounting frame and the base are connected to form a whole; when it is necessary to replace the light source component, the transmission rod is rotated so that the upper clamping part at the top of the transmission rod moves into the clamping groove, and the lower clamping part at the bottom of the transmission rod is opposite to the avoidance hole. When the base moves down, the upper clamping part is cooperated in the clamping groove to realize the hanging of the outer mounting frame in the outer shell, and the avoidance hole can provide avoidance space for the lower clamping part, so that the base and the outer mounting frame are relatively separated.

[0008] As a further improvement to the above technical solution, an elastic member is provided between the upper clamping block and the top side of the outer mounting frame, and a first positioning groove is provided on the top side of the clamping groove. When the upper clamping portion rotates into the clamping groove and faces the first positioning groove, the elastic member can press the upper clamping portion into the first positioning groove. When the outer mounting frame needs to be relatively fixed to the outer shell, the upper clamping portion rotates into the clamping groove. When the upper clamping portion is rotated into place, it faces the first positioning groove. At this time, the elastic force of the elastic member can press the upper clamping portion into the first positioning groove. This can better maintain the relative fixation between the outer mounting frame and the outer shell and enhance the feel after the transmission rod is rotated into place.

[0009] As a further improvement to the above technical solution, a second positioning groove is provided on the bottom side of the base. When the lower clamping portion is offset from the avoidance hole and aligned with the second positioning groove, the elastic member can drive the lower clamping portion to move upward and enter the second positioning groove. When the outer mounting frame needs to be relatively fixed to the base, the lower clamping portion is rotated to be offset from the avoidance hole and aligned with the second positioning groove after being rotated into position. At this time, the elastic force of the elastic member pushes the clamping block upward, driving the transmission rod upward, thereby driving the lower clamping portion to move upward and enter the second positioning groove. This can better maintain the relative fixation between the outer mounting frame and the base, and further enhance the feel after the transmission rod is rotated into position.

[0010] As a further improvement of the above technical solution, a plurality of locking assemblies are provided around the support column. The plurality of locking assemblies can fix the outer mounting frame relative to the housing or the base at multiple positions, thereby improving the stability of the overall structure.

[0011] As a further improvement to the above technical solution, the outer mounting frame includes columns and connecting rods. Multiple columns are arranged around the support columns, with the connecting rods connecting between two adjacent columns. Multiple transmission rods are respectively inserted through the multiple columns. The multiple columns and transmission rods form a frame structure, allowing images and other display content to be displayed between two adjacent columns. Multiple locking assemblies are correspondingly provided at the positions of the multiple columns, securing the outer mounting frame relative to the housing or base at the corners of the frame.

[0012] As a further improvement to the above technical solution, the support column is provided with a threaded segment, and the lifting drive element includes a hollow motor mounted on the base. The hollow motor is drivingly connected to a transmission sleeve, which is threadedly connected to the threaded segment, and the outer mounting frame is slidably connected to the outer shell. When the base needs to be moved up and down, the hollow motor drives the transmission sleeve to rotate forward or reverse. Due to the interaction between the transmission sleeve and the threaded segment, and the sliding connection between the outer mounting frame and the outer shell, the forward and reverse rotation of the transmission sleeve can drive the base to move up and down along the support column.

[0013] As a further improvement to the above technical solution, the base is connected to a mounting sleeve that is sleeved onto the outside of the support column. The hollow motor is connected to the top of the mounting sleeve, and the threaded segment is formed on the top of the support column. The mounting sleeve elevates the hollow motor within the housing, allowing the threaded segment to be positioned inside the housing, reducing exposure and facilitating smoother and more stable rotation of the transmission sleeve relative to the threaded segment.

[0014] As a further improvement of the above technical solution, the light source assembly is detachably connected to the inner mounting frame. The light source assembly can be removed from the inner mounting frame, so that the light source assembly can be easily replaced and maintained. BRIEF DESCRIPTION OF THE DRAWINGS

DETAILED DESCRIPTION

[0021] The following will clearly and completely describe the concept, specific structure and technical effects of the present invention in combination with the embodiments and drawings, so as to fully understand the purpose, characteristics and effects of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. Based on the embodiments of the present invention, other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present invention. In addition, all the connection relationships mentioned in the text do not refer to the direct connection of components, but refer to the fact that a better connection structure can be formed by adding or reducing connecting accessories according to the specific implementation situation. The various technical features in the invention can be combined interactively without conflicting with each other.

[0022] Reference Figure 1 and Figure 2 , a lifting and disassembling advertising light box, comprising: a shell 100, the bottom side of which is provided with an opening, and multiple sides of the shell 100 are provided with transparent plates; a support base 210, the top side of which is connected to a support column 220, the support column 220 upwardly passes through the opening and is connected to the inner top side of the shell 100; a lifting mechanism, comprising a lifting drive member, a base 310, an outer mounting frame 320 and an inner mounting frame 330, the lifting drive member is provided on the support column 220, and the lifting drive member is in transmission connection with the support base 210 Then, the lifting drive member can drive the base 310 to cover the opening upward or open the opening downward, and the inner mounting frame 330 and the outer mounting frame 320 are arranged on the top side of the base 310 along the direction away from the support column 220. The inner mounting frame 330 is provided with a light source assembly 350, and the light source assembly 350 can emit light in the direction of the outer mounting frame 320. The light source assembly 350 includes a lamp board installed on the inner mounting frame 330, and a plurality of lamp beads are arranged on the lamp board, and the lighting function is realized by the plurality of lamp beads.

[0023] In this lifting and disassembling advertising light box, the shell 100 is connected to the support column 220, and the support column 220 is used to raise the height of the shell 100. The outer mounting frame 320 is used to install display content such as canvas, while the inner mounting frame 330 located inside is used to install the light source assembly 350. During operation, the light source assembly 350 emits light to the display content such as canvas to achieve a lighting display effect. When the display content such as canvas needs to be replaced, the lifting drive component drives the base 310 to move downward and drives the inner mounting frame 330 and the outer mounting frame 320 to move downward from the opening to the base 310. At this time, the display content such as canvas is directly exposed and the height is reduced, which can be replaced conveniently and quickly. Then, the lifting drive component is used to drive the base 310 to move upward again, so that the base 310 covers the opening upward. In this way, the display content such as canvas can be removed and replaced from the shell 100 by lifting, which greatly improves the convenience and efficiency of the entire operation process. There is no need to use tools such as escalators to reach the working height, which improves the safety of operation.

[0024] In the above embodiment, when the base 310 is moved downward, the outer mounting frame 320 and the inner mounting frame 330 will be driven downward together. Since the outer mounting frame 320 will block the inner mounting frame 330, it is not convenient to replace and maintain the light source assembly 350 on the inner mounting frame 330. Therefore, in this embodiment, a locking assembly is provided between the outer mounting frame 320, the outer shell 100 and the base 310, and the locking assembly can connect the outer mounting frame 320 to the outer shell 100 or the base 310. The outer mounting frame 320 can be fixed relatively to the outer shell 100 or switched to be fixed to the base 310 through the locking component. When it is necessary to replace the display content such as the canvas, the locking component connects the outer mounting frame 320 to the base 310. At this time, moving the base 310 downward can drive the inner mounting frame 330 and the outer mounting frame 320 to move downward at the same time, so that the canvas and other displays on the outer mounting frame 320 can be easily replaced; when it is necessary to maintain the light source assembly 350, the locking component connects the outer mounting frame 320 to the outer shell 100. At this time, moving the base 310 downward only drives the inner mounting frame 330 to move downward together, so that the light source assembly 350 is directly exposed and can be easily maintained.

[0025] As a specific structural embodiment of the locking assembly, Figure 3 and Figure 4As shown, the locking assembly includes a transmission rod 410, an upper clamping block 420, a lower clamping block 430 and a hanging block 440, the hanging block 440 is connected to the inner top side of the shell 100, and a clamping groove 441 is provided on one side of the hanging block 440. The transmission rod 410 is rotated along the axis in the up and down directions and is connected to the outer mounting frame 320. The top end of the transmission rod 410 extends out of the outer mounting frame 320 and is connected to the upper clamping block 420. The end of the upper clamping block 420 is formed with an upper clamping portion. The bottom end of the transmission rod 410 passes downward through the base 310 and is connected to the lower clamping block 430. A lower clamping portion is formed at the end of the lower clamping block 430. The base 310 is provided with an avoidance hole corresponding to the position of the lower clamping portion. When the transmission rod 410 rotates, it can drive the upper clamping portion to rotate into the clamping groove 441, and the lower clamping portion is opposite to the avoidance hole, or drive the lower clamping portion to rotate out of the clamping groove 441, and the lower clamping portion is staggered with the avoidance hole. When it is necessary to replace the display content such as the canvas, the transmission rod 410 is rotated so that the upper clamping part at the top of the transmission rod 410 moves out of the clamping groove 441, and the lower clamping part at the top of the transmission rod 410 is staggered with the avoidance hole, so that the outer mounting frame 320 and the base 310 are connected to form a whole; when it is necessary to replace the light source assembly 350, the transmission rod 410 is rotated so that the upper clamping part at the top of the transmission rod 410 moves into the clamping groove 441, and the lower clamping part at the bottom of the transmission rod 410 is opposite to the avoidance hole. When the base 310 moves downward, the upper clamping part is engaged in the clamping groove 441 to realize hanging the outer mounting frame 320 in the shell 100, and the avoidance hole can provide avoidance space for the lower clamping part, so that the base 310 and the outer mounting frame 320 are relatively separated.

[0026] To facilitate sensing whether the desired travel position has been reached when rotating the transmission rod 410, in this embodiment, an elastic member 450 is disposed between the upper clamping block 420 and the top side of the outer mounting frame 320. The elastic member 450 can be an elastic structural member such as rubber or a spring. A first positioning groove 442 is disposed on the top side of the clamping groove 441. When the upper clamping portion rotates into the clamping groove 441 and faces the first positioning groove 442, the elastic member 450 presses the upper clamping portion into the first positioning groove 442. When the outer mounting frame 320 needs to be fixed relative to the housing 100, the upper clamping portion rotates into the clamping groove 441. When the upper clamping portion is fully rotated, it faces the first positioning groove 442. The elastic force of the elastic member 450 presses the upper clamping portion into the first positioning groove 442. This better maintains the relative fixation between the outer mounting frame 320 and the housing 100 and enhances the feel after the transmission rod 410 is fully rotated.

[0027] Furthermore, a second positioning slot is provided on the bottom side of the base 310. When the lower clamping portion is offset from the avoidance hole and aligned with the second positioning slot, the elastic member 450 can drive the lower clamping portion upward into the second positioning slot. When the outer mounting frame 320 needs to be relatively fixed to the base 310, the lower clamping portion is rotated to be offset from the avoidance hole and aligned with the second positioning slot after being rotated into position. At this time, the elastic force of the elastic member 450 pushes up the clamping block 420, driving the transmission rod 410 upward, thereby driving the lower clamping portion upward into the second positioning slot. This can better maintain the relative fixation between the outer mounting frame 320 and the base 310 and further enhance the feel after the transmission rod 410 is rotated into position.

[0028] Furthermore, a plurality of locking assemblies are provided around the support column 220. The plurality of locking assemblies can fix the outer mounting frame 320 relative to the housing 100 or the base 310 at a plurality of positions, thereby improving the stability of the overall structure.

[0029] In actual applications, the housing 100 may be provided with only one, two, three, or four transparent panels. Correspondingly, the outer mounting frame 320 also needs to be provided with a supporting connection structure corresponding to the number of transparent panels, so that display contents such as canvases can be installed. In this embodiment, the outer mounting frame 320 includes columns and connecting rods. The columns are provided in plurality around the support columns 220, and the connecting rods are connected between two adjacent columns. In this case, the two adjacent columns and the connecting rods between the two columns form a supporting connection structure, and the plurality of transmission rods 410 are respectively provided through the plurality of columns. The plurality of columns and the transmission rods 410 form a frame structure. In this case, display contents such as pictures can be displayed between two adjacent columns. The plurality of locking components are correspondingly provided at the positions of the plurality of columns, and the outer mounting frame 320 is fixed relative to the housing 100 or the base 310 at the corners.

[0030] The lifting drive member can be a linear drive source such as an electric screw, a pneumatic cylinder, or a hydraulic cylinder. In order to improve the compactness of the overall structure, in this embodiment, the support column 220 is provided with a threaded section. The lifting drive member includes a hollow motor 341 provided on the base 310. The hollow motor 341 is in driving connection with a transmission sleeve 342, which is threadedly connected to the threaded section. The outer mounting frame 320 is slidably connected to the housing 100. When the base 310 needs to be moved up and down, the hollow motor 341 drives the transmission sleeve 342 to rotate forward or reverse. Due to the mutual cooperation between the transmission sleeve 342 and the threaded section, and the sliding connection between the outer mounting frame 320 and the housing 100, the base 310 can be driven to move up and down along the support column 220 as the transmission sleeve 342 rotates forward and reverse.

[0031] Furthermore, the base 310 is connected to a mounting sleeve 311, which is sleeved onto the outside of the support column 220. The hollow motor 341 is connected to the top of the mounting sleeve 311, and the threaded section is formed on the top of the support column 220. The mounting sleeve elevates the installation height of the hollow motor 341 within the housing 100. In this case, the threaded section can be positioned inside the housing 100, reducing exposure, which helps to improve the smoothness and stability of the relative rotation of the transmission sleeve 342 on the threaded section.

[0032] In some embodiments, the light source assembly 350 is detachably connected to the inner mounting frame 330, for example, by a snap fastener or screws. The light source assembly 350 can be removed from the inner mounting frame 330, making it easy to replace and maintain the light source assembly 350.

[0033] The above specifically describes the preferred embodiments of the present invention, but the invention is not limited to the embodiments. Those skilled in the art may make various equivalent modifications or substitutions without violating the spirit of the present invention. These equivalent modifications or substitutions are all included in the scope defined by the claims of this application.
