Description

Technical Field

[0001] This invention belongs to the technical field of art promotion devices, specifically relating to an adjustable exhibition wall for art promotion. Background Technology

[0002] In the field of cultural and artistic dissemination and exhibition, art promotion and exhibition walls serve as a core medium connecting artworks, curatorial concepts, and the audience. Their development is deeply intertwined with the iterations of material technology, digital multimedia technology, and spatial interaction technology, evolving from simple static displays to multi-faceted dynamic interactions. Early art promotion and exhibition walls were primarily based on traditional physical exhibition walls, with relatively simple technological systems. In terms of materials, cement mortar plastered walls, gypsum board walls, or wooden decorative panels are commonly used. Some high-end art galleries will choose professional exhibition walls covered with linen. The core function of these materials is to provide a flat, non-reflective basic display surface, which is suitable for the display needs of static two-dimensional art such as oil paintings, traditional Chinese paintings, and photographs. In terms of display format, it mainly relies on basic fixing devices such as hanging rails and exhibition board brackets, combined with lighting equipment such as spotlights and softboxes to present the works. The publicity function is accomplished by pasting paper posters, roll-up banners, and brief nameplates on the walls. The information transmission dimension is single, and the updating of exhibition content requires manual disassembly and replacement of materials, which is inefficient. At the same time, due to the limitation of physical space, it is impossible to achieve the reuse of art content across regions and multiple sessions.

[0003] Existing adjustable exhibition walls used for art promotion lack a cleaning mechanism on their outer surface. As a result, stains that adhere to the wall surface require manual cleaning, which is time-consuming, labor-intensive, and inconvenient to use. Summary of the Invention

[0004] This invention provides an adjustable exhibition wall for art promotion, which aims to solve the problem that existing adjustable exhibition walls for art promotion do not have a cleaning structure installed on their outer surface, resulting in the need for manual cleaning after stains adhere to the surface of the display wall, which is time-consuming, labor-intensive, and very inconvenient to use.

[0005] This invention provides an adjustable exhibition wall for art promotion, comprising an adjustable base, a frame mounted on the upper end of the adjustable base, a protective glass fixed to the opening on the front of the frame, an electronic display screen mounted on the inner side of the frame, a cover plate detachably connected to the opening on the back of the frame, and a cleaning mechanism mounted on the top of the front of the frame for cleaning the protective glass.

[0010] Furthermore, a support frame is installed between the connecting block and the sawtooth rod. The support frame includes a support platform fixed to the connecting block and a rotating tube A swivelly connected to the support platform. The rotating tube A and the sawtooth wall of the sawtooth rod rotate and fit together.

[0011] Furthermore, the silicone strip is locked between the outer shell and the pressure plate. The pressure plate is fixed to the outer shell via a connector. A protrusion is installed on one side wall of the pressure plate, and a through groove matching the protrusion is reserved on the silicone strip.

[0012] Furthermore, the connecting block has multiple through holes. Inside the through holes, the rotating tube B is connected to the stop unit. The stop unit includes a rotating rod and a locking post and a rotating platform, which are fixed to both sides of the rotating rod. The locking post is locked into the rotating tube B. The rotating platform has a polygonal opening on the side farther from the rotating rod.

[0013] Furthermore, the traction unit includes a rotating column and a motor. The outer circumferential surface of the rotating column has a threaded opening. Sprockets are installed on the outer surface of the rotating column and the rotating part of the motor. The sprockets on the motor are linked to the sprockets on the rotating column via a chain. The rotating table is threaded onto the outer circumferential surface of the rotating column, and the rotating table and the connecting piece are fixedly connected.

[0014] Furthermore, the connector includes a slot A pre-drilled on the outer wall of the housing and a slot B pre-drilled on the silicone strip and the pressure plate. A pair of mounting grooves are pre-drilled on the peripheral wall of slot A. A spiral beryllium copper wire B is fixed to the bottom wall of the mounting groove, and a wedge-shaped locking block is fixed to the other side of the spiral beryllium copper wire B. The wedge-shaped locking block is movably connected to the mounting groove. A T-shaped insert is inserted into slot B, with one end of the T-shaped insert inserted into slot A.

[0019] To make the objectives, technical solutions, and advantages of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. The same reference numerals in the drawings represent the same components. It should be noted that the described embodiments are only some, not all, of the embodiments of the present invention. All other embodiments obtained by those skilled in the art based on the described embodiments of the present invention without creative effort are within the scope of protection of the present invention.

[0020] Reference Figures 1-2This invention proposes an adjustable exhibition wall for art promotion, comprising an adjustable base 1, a frame 2 mounted on the upper end of the adjustable base 1, a protective glass 3 fixedly connected to the opening on the front of the frame 2, an electronic display screen 4 mounted on the inner side of the frame 2, a cover plate 5 detachably connected to the opening on the back of the frame 2, a cleaning mechanism 6 mounted on the top of the front of the frame 2 for cleaning the protective glass 3, an electrical socket and a switch mounted on one side of the frame 2, and a PLC controller mounted on the inner side of the frame 2. The electrical socket, switch, PLC controller and cleaning mechanism 6 are electrically connected. The electrical socket, switch and PLC controller are all prior art and will not be described in detail here.

[0021] The height of the display wall can be adjusted by the adjustable base 1 to meet different display scenarios. The cleaning mechanism 6 can clean the protective glass 3 at regular intervals to ensure the display effect of the display wall. It is time-saving, labor-saving and very convenient to use.

[0022] Reference Figure 1 The adjustable base 1 includes a placement base 11, with a sleeve 12 fixedly connected to the upper end of the placement base 11. An inner tube 13 is fitted inside the sleeve 12. Several threaded holes are reserved on the outer wall of the inner tube 13, and a through hole is reserved on the outer wall of the sleeve 12. A threaded knob 14 is installed on the outside of the sleeve 12. The threaded end of the threaded knob 14 passes through the through hole and is threadedly connected to the threaded hole. When it is necessary to adjust the height of the display wall, the threaded knob 14 is unscrewed, the inner tube 13 is pulled, and the electronic display screen 4 is placed at the required height. Then the threaded knob 14 is screwed into the threaded hole to lock the inner tube 13 in the sleeve 12. It is very convenient to use.

[0023] Reference Figures 3-13 The cleansing mechanism 6 includes a connecting block 61 and a traction unit installed on the upper outer side of the frame 2. The connecting block 61 and the traction unit are installed on the upper outer side of the frame 2 to prevent the traction unit from obscuring the content displayed on the display wall, and the frame 2 can protect against dust and rain to prevent the traction unit from being corroded and ensure that the traction unit can work for a long time.

[0024] The traction unit is used to pull the connecting block 61 back and forth along the vertical direction of the protective glass 3 to assist the silicone strip 613 installed on the connecting block 61 in cleaning the protective glass 3. The protective glass 3 is square, and the driving connecting block 61 can pull the connecting block 61 back and forth along the vertical edge of the protective glass 3. When the connecting block 61 moves back and forth, the silicone strip 613 can clean the outer wall of the protective glass 3, remove the adhesive on the outer wall, and ensure the cleanliness of the protective glass 3 so that the display wall can be clearly displayed.

[0025] The traction unit includes a connecting piece 63. A groove 601 is reserved on the side wall of the frame 2. The connecting piece 63 passes through the groove 601. The purpose of the connecting piece 63 is to transmit the traction action of the traction unit to the connecting block 61, so that the connecting block 61 can be moved by the traction unit. Therefore, the connecting piece 63 adopts a sheet-like structure, which can narrow the span of the groove 601 on the frame 2, thereby reducing the volume of the frame 2 to some extent. For example, the wider the groove 601, the wider the wall of the frame 2, resulting in a larger volume.

[0026] The edge of the connecting block 61 is movably connected to the connecting piece 63, allowing the connecting block 61 to move back and forth through the serrated rod 611 to achieve the purpose of approaching or moving away from the protective glass 3. The serrated rod 611 is fixed to the inner edge of the outer wall of the frame 2, and its serrated wall surface is set facing the connecting block 61. The movable connection position between the connecting piece 63 and the connecting block 61 is such that the connecting block 61 can move along the direction of approaching or moving away from the protective glass 3. A spiral beryllium copper wire A67 is installed on the connecting block 61 to drive the connecting block 61 to approach the protective glass 3. Then, when the connecting block 61 is pulled by the traction unit to move, the connecting block 61 will have vertical interval movement due to the serrated wall surface on the serrated rod 611, that is, continuously approaching and moving away from the protective glass 3, so that the silicone strip 613 can perform orderly pressing and loosening, and adjust the strength of the pressure between the silicone strip 613 and the outer wall of the protective glass 3. The pressure and relaxation of the silicone strip 613 can be adjusted according to the actual situation. For example, when the connecting block 61 moves upward to the furthest distance from the protective glass 3, the silicone strip 613 can not only be adjusted so that its lower end fits against the outer wall of the protective glass 3, but also the silicone strip 613 can be adjusted so that its lower end is slightly bent.

[0027] The lower end of the silicone strip 613 is formed by cuts 6133 to form multiple cleaning ends 6134; that is, the lower end of the silicone strip 613 is not a whole structure, but is composed of several cleaning ends 6134. When the distance between the connecting block 61 and the protective glass 3 is the shortest under the cooperation of the serrated rod 611, several cleaning ends 6134 will bend. Each cut 6133 can clean the outer wall of the protective glass 3 during the change, improve the cleaning function, and remove the adhesives attached to the outer wall of the protective glass 3.

[0028] A housing 62 is movably mounted on the outer wall of the connecting block 61. The housing 62 can move along the outer wall of the connecting block 61. A silicone strip 613 is fixed to the housing 62. An assist unit is screwed between the housing 62 and the connecting piece 63. When the connecting block 61 moves from the arch end 6111 of the serrated rod 611 to the concave end 6112, the lower end of the silicone strip 613 presses against the outer wall of the protective glass 3 and bends. The assist unit pulls the housing 62 to move along the connecting block 61. The cleaning end 6134 and the outer shell 62 work together to achieve the purpose of thoroughly cleaning the protective glass 3. With the assistance of the assist unit, the outer shell 62 can change the vertical back-and-forth movement of the connecting block 61 to the horizontal back-and-forth movement of the silicone strip 613, and then clean the outer wall of the protective glass 3 through the corner of the side of the cleaning end 6134. Since each cleaning end 6134 has two pairs of corners and there are many cleaning ends 6134, the function of removing adhesives is enhanced.

[0029] The silicone strip 613 is locked between the outer shell 62 and the pressure plate 614.

[0030] The pressure plate 614 is fixed to the outer shell 62 via the connector 615; a protrusion 6141 is installed on one side wall of the pressure plate 614, and a through groove 6135 matching the protrusion 6141 is reserved on the silicone strip 613; the protrusion 6141 and the through groove 6135 cooperate to precisely limit the position of the silicone strip 613, ensuring that the lower end of the silicone strip 613 is facing the outer wall of the protective glass 3.

[0031] Reference Figure 14 and Figure 15The connector 615 includes a slot A6151 pre-drilled on the outer wall of the housing 62 and a slot B6155 pre-drilled on the silicone strip 613 and the pressure plate 614. A pair of mounting grooves 6152 are pre-drilled on the peripheral wall of slot A6151. A spiral beryllium copper wire B6153 is fixedly connected to the bottom wall of the mounting groove 6152. A wedge-shaped locking block 6154 is fixedly connected to the other side of the spiral beryllium copper wire B6153. The wedge-shaped locking block 6154 is movably connected to the mounting groove 6152. A T-shaped insert 6156 is inserted into slot B6155. One end of the T-shaped insert 6156 is inserted into slot A6151. The end of the T-shaped insert 6156 in slot A6151 is tapered. An annular locking groove 6157 is pre-drilled on the outer peripheral surface of the end of the T-shaped insert 6156 in slot A6151. The wedge-shaped locking block 6154 engages with the T-shaped insert 6154. In the annular locking groove 6157, a T-shaped movable groove 6158 is pre-reserved in the center of one outer end of the T-shaped insert rod 6156. A movable rod 6159 is movably installed in the T-shaped movable groove 6158. A spiral beryllium copper wire C61510 is clamped to the outer circumference of the movable rod 6159. Both ends of the spiral beryllium copper wire C61510 are fixedly connected to the movable rod 6159 and the wall of the T-shaped movable groove 6158, respectively. A connecting groove 61511 is reserved on the right wall of the tight groove 6157. The other side of the connecting groove 61511 is connected to the T-shaped movable groove 6158. The movable rod 6159 is fixed to the disassembly block 61512 on one side in the T-shaped movable groove 6158. The other side of the disassembly block 61512 is movably installed in the connecting groove 61511. One side of the disassembly block 61512 is in contact with the inclined surface of the wedge-shaped locking block 6154.

[0032] When assembling the silicone strip 613, first attach the silicone strip 613 to the outer wall of the outer shell 62, then attach the pressure plate 614 to the wall of the silicone strip 613, and align the slots A6151 and B6155. Insert the T-shaped insert 6156 into the slot A6151 along the slot B6155. As the T-shaped insert 6156 enters the slot A6151, it first contacts the wedge-shaped locking block 6154. The T-shaped insert 6156 pushes the wedge-shaped locking block 6154 outward toward the assembly groove 6152. When the annular locking groove 6157 moves to face the wedge-shaped locking block 6154, under the action of the spiral beryllium copper wire B6153, the wedge-shaped locking block 6154 engages in the annular locking groove 6157. At this moment, the T-shaped insert aligns with the outer shell 62 and the silicone strip 6153. 3. The pressure plate 614 is locked. When it is necessary to disassemble and replace the silicone strip 613, press the movable rod 6159. The movable rod 6159 drives the disassembly block 61512 to move. The disassembly block 61512 moves toward the wedge-shaped locking block 6154. The disassembly block 61512 presses the wedge-shaped locking block 6154. Under the action of its inclined surface, the wedge-shaped locking block 6154 moves toward the assembly groove 6152. When one side of the disassembly block 61512 moves to be in contact with the left wall of the annular locking groove 6157, the wedge-shaped locking block 6154 is completely moved into the assembly groove 6152. At this time, the T-shaped insert rod 6156 can be pulled out to disassemble the silicone strip 613. Then, the new silicone strip 613 can be installed according to the above steps. This realizes the quick assembly and disassembly of the silicone strip 613, which is convenient for replacement.

[0033] The traction unit includes a rotating column 618 and a motor 619. The outer circumferential surface of the rotating column 618 is pre-threaded. Both the outer surface of the rotating column 618 and the rotating part of the motor 619 are equipped with sprockets. The sprocket on the motor 619 is linked to the sprocket on the rotating column 618 via a chain 621. The outer circumferential surface of the rotating column 618 is threaded to a moving platform 620. The moving platform 620 and the connecting piece 63 are fixedly connected.

[0034] Multiple through holes 6101 are reserved on the connecting block 61. Inside the through hole 6101, the rotating tube B616 is connected by the stop unit 617. When the outer shell 62 moves on the connecting block 61, the rotating tube B616 moves in the through hole 6101. The rotation reduces the obstruction between the connecting block 61 and the outer shell 62.

[0035] The stop unit 617 includes a rotating rod 6171 and a locking post 6172 and a rotating platform 6173, which are fixed to both sides of the rotating rod 6171. The central axes of the rotating rod 6171, the locking post 6172 and the rotating platform 6173 are all coincident. The outer circumferential surface of the rotating rod 6171 is reserved with a threaded opening. The locking post 6172 is embedded in the rotating tube B616. The side of the rotating platform 6173 that is farthest from the rotating rod 6171 is reserved with a polygonal opening 6174, which makes it convenient for manual use of tools to twist the rotating rod 6171.

[0036] The connecting block 61 is movably connected to the connecting piece 63 via its edge. With the assistance of the serrated wall of the serrated bar 611, the connecting block 61 can repeatedly move closer to or away from the protective glass 3 during its linear movement. This adjusts the resistance between the silicone strip 613 and the protective glass 3. Then, with the cooperation of the assist unit and the housing 62, the repeated movement of the connecting block 61 towards or away from the protective glass 3 can be transformed into the horizontal back-and-forth movement of the silicone strip 613. This allows the outer wall of the protective glass 3 to be cleaned via the corner of the cleaning end 6134, removing any adhering substances and ensuring the cleanliness of the outer wall of the protective glass 3, thereby guaranteeing the display effect of the display wall.

[0037] The silicone strip 613 includes an assembly end 6131 with a constant wall thickness and a wedge-shaped end 6132 installed at the lower end of the assembly end 6131. ​​As it gradually approaches the protective glass 3, the wall thickness of the wedge-shaped end 6132 gradually decreases. Because the wall thickness of the wedge-shaped end 6132 gradually decreases as it approaches the protective glass 3, as the connecting block 61 gradually moves towards the protective glass 3, the wall thickness at the bend of the cleaning end 6134 gradually increases, thereby increasing the pressure between the cleaning end 6134 and the protective glass 3.

[0038] The active connection structure between the edge of the connecting block 61 and the connecting piece 63 is described below.

[0039] The upper end of the connecting piece 63 is fixedly connected to the guide post 64, and the upper end of the guide post 64 is fixedly connected to the movable block 66. A guide platform 65 is movably mounted on the guide post 64, and a spiral beryllium copper wire A67 is installed between the guide platform 65 and the movable block 66. One side of the movable block 66 is fixedly connected to the bracket B610, and the upper end of the outer shell 62 is fixedly connected to the bracket A69. The assist unit is screwed between the bracket A69 and the bracket B610. The assist unit includes an O-shaped rod 68, which includes a pair of long rods 681 and a pair of short rods 682 fixed to the ends of the pair of long rods 681. Each of the pair of short rods 682 is screwed to the bracket A69 and the bracket B610.

[0040] To enhance the smoothness and stability of the equipment, a support frame 612 is installed between the connecting block 61 and the sawtooth rod 611. The support frame 612 includes a support platform 6121 fixedly connected to the connecting block 61 and a rotating tube A6122 spun to the support platform 6121. The rotating tube A6122 and the sawtooth wall of the sawtooth rod 611 rotate and fit together. By replacing the translational fit with a rotating fit, the obstruction between the connecting block 61 and the sawtooth rod 611 can be reduced.

[0041] The foregoing has shown and described the basic principles, main features, and advantages of the present invention. Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention. Various changes and modifications can be made to the invention without departing from its spirit and scope, and all such changes and modifications fall within the scope of the present invention as claimed. The scope of protection of this invention is defined by the appended claims and their equivalents.
