Description

Technical Field

[0001] This application relates to the field of exhibition booth technology, specifically to a load-bearing adjustment device for an art exhibition booth. Background Technology

[0002] The art exhibits cover a variety of categories, including calligraphy and paintings by famous artists, three-dimensional sculptures, intangible cultural heritage crafts, antiques and cultural relics, and exquisite ornaments. These exhibits are generally characterized by high value, fragile texture, easy to be bumped and damaged, and exquisite design. They have high requirements for the flatness, stability and safety of the display and placement. All of them need to be supported, placed, isolated and protected and displayed in a standardized manner using special exhibition stands.

[0003] However, most traditional art exhibition booths currently have fixed and simple structures. Fixed booths can become tilted or shifted due to uneven ground, site subsidence, or relocation. This not only affects the aesthetics and visual appeal of the exhibits, but also causes small ornaments and handicrafts to slip and tip over under long-term tilting stress, damaging valuable exhibits. In addition, conventional booths have weak anti-tipping protection capabilities. Under conditions such as crowds, collisions, accidental impacts, ground subsidence, or slight shaking from earthquakes, booths are prone to tipping over, directly causing exhibits to break or be damaged. Existing booths lack active anti-tipping buffer protection structures, making it difficult to avoid the risk of tipping over at the source. Summary of the Invention

[0004] The purpose of this application is to provide an art exhibition stand support and adjustment device to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this application provides the following technical solution: an art exhibition stand load-bearing adjustment device, comprising a stand frame, a horizontal adjustment mechanism, and a tilt protection mechanism; The platform includes an internal support platform, a support plate fixedly connected to the inner wall of the platform, a transparent cover hinged to the top of the platform, tilt sensors installed on both sides and the front surface of the support platform, a touch screen all-in-one machine installed on the front surface of the platform and connected to the tilt sensors, a horizontal adjustment mechanism installed on the top of the support plate and used to support and horizontally adjust the support platform, and a tilt protection mechanism installed around the platform to protect the platform from tilting by inflating folded airbags.

[0006] Preferably, the horizontal adjustment mechanism includes two U-shaped brackets symmetrically installed on the top of the support plate. A first U-shaped plate is installed on the top of each of the two U-shaped brackets. A first connecting rod is hinged to both ends of the first U-shaped plate.

The U-shaped rods pass through the connecting sleeves. A motor is installed on the top of the support plate. A bidirectional threaded rod is fixedly connected to the rotating shaft of the motor. One end of the bidirectional threaded rod passes through the hinge joint of the first and second connecting rods.

[0007] Preferably, the tipping protection mechanism includes four high-pressure gas cylinders, which are symmetrically installed around the bottom of the platform. The top of the platform is provided with grooves around its perimeter, and folded airbags are installed inside the grooves. The air outlets of the high-pressure gas cylinders are connected to air supply pipes. One end of the air supply pipe passes through the grooves and is connected to the interior of the folded airbags. A solenoid valve is installed on the air supply pipe.

[0008] Preferably, a sleeve is hinged at the top center of the support plate, and a ball joint rod is installed inside the sleeve via a spring.

Detailed Implementation

[0018] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. Based on the embodiments of this application, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this application.

[0019] Please see Figures 1-3 The embodiments of this application provide an art exhibition stand support adjustment device, including: a stand 1, a horizontal adjustment mechanism 4 and a tilt protection mechanism 5.

[0020] like Figures 1-3 As shown, the platform 1 has a support platform 3 inside, and a support plate 2 is fixedly connected to the inner wall of the platform 1. A transparent cover 7 is hinged to the top of the platform 1. Tilt sensors 13 are installed on both sides and the front surface of the support platform 3. A touch screen all-in-one machine 6 is installed on the front surface of the platform 1. The touch screen all-in-one machine 6 is connected to the tilt sensor 13. A horizontal adjustment mechanism 4 is installed on the top of the support plate 2. The horizontal adjustment mechanism 4 is used to support and horizontally adjust the support platform 3. A tilt protection mechanism 5 is installed around the platform 1. The tilt protection mechanism 5 is used to protect the platform 1 by inflating the folded airbag 506 when it tilts.

[0021] In this embodiment, as Figure 2 , Figure 4 and Figure 6 As shown, the horizontal adjustment mechanism 4 includes two U-shaped brackets 401 symmetrically installed on the top of the support plate 2. A first U-shaped plate 402 is installed on the top of each of the two U-shaped brackets 401. A first connecting rod 403 is hinged to both ends of the first U-shaped plate 402. A second connecting rod 404 is hinged to the end of each of the first connecting rods 403. A second U-shaped plate 405 is hinged to the adjacent end of each of the two second connecting rods 404. A connecting sleeve 409 is fixedly connected to the top of the second U-shaped plate 405. Two U-shaped rods 408 are symmetrically installed on the bottom of the support platform 3. The U-shaped rods 408 pass through the connecting sleeves 409. A motor 406 is installed on the top of the support plate 2. A bidirectional threaded rod 407 is fixedly connected to the rotating shaft of the motor 406. One end of the bidirectional threaded rod 407 passes through the hinge of the first connecting rod 403 and the second connecting rod 404.

[0022] When the horizontal adjustment mechanism 4 is in use, the U-shaped bracket 401 serves as a mounting support for the first U-shaped plate 402 and the motor 406. The motor 406 drives the bidirectional threaded rod 407 to rotate forward and backward. Utilizing the bidirectional thread characteristics, it drives the hinge points of the first connecting rod 403 and the second connecting rod 404 on both sides to move synchronously towards or away from each other. Through the scissor-like telescopic movement of the connecting rod, the second U-shaped plate 405 is raised and lowered. With the sliding adaptation structure of the connecting sleeve 409 and the U-shaped rod 408, the height of the left and right sides of the support platform 3 can be independently fine-tuned. Combined with the real-time horizontal data feedback from the tilt sensor 13, the tilt deviation of the support platform 3 is automatically corrected to ensure that the exhibits are always placed horizontally.

[0023] Furthermore, a sleeve 14 is hinged at the top center of the support plate 2. A ball joint rod 15 is installed inside the sleeve 14 via a spring. A ball joint connector 16 is installed at the bottom of the support platform 3. The top end of the ball joint rod 15 is rotatably installed inside the ball joint connector 16. The ball joint rod 15 and the ball joint connector 16 cooperate to form a universal hinge support structure, which serves as the central support base of the support platform 3 and provides support for the multi-angle horizontal fine adjustment of the support platform 3. The ball joint rod 15, in conjunction with the spring inside the sleeve 14, keeps itself always upright inside the ball joint connector 16.

[0024] In addition, refer to Figure 2 and Figure 5 The top of the support plate 2 is hinged with a pneumatic lifting rod 10. One end of the pneumatic lifting rod 10 is hinged to the bottom of the transparent cover 7. The pneumatic lifting rod 10 realizes the opening and closing and lifting of the transparent cover 7 through the telescopic action. The opening and closing process is smooth and controllable.

[0025] Among them, such as Figures 1-3 As shown, the tipping protection mechanism 5 includes four high-pressure gas cylinders 502. The four high-pressure gas cylinders 502 are symmetrically installed around the bottom of the platform 1. The top of the platform 1 is provided with grooves 505 around the top. A folding airbag 506 is installed inside the groove 505. The air outlet of the high-pressure gas cylinder 502 is connected to an air supply pipe 504. One end of the air supply pipe 504 passes through the groove 505 and is connected to the inside of the folding airbag 506. A solenoid valve 503 is installed on the air supply pipe 504.

[0026] The tipping protection mechanism 5 is supplied with air by four high-pressure gas tanks 502 around the bottom of the platform 1. The solenoid valve 503 controls the opening and closing of the air supply pipe 504 to inflate the folded airbags 506 in the groove 505. When the tilt sensor 13 detects that the platform 1 is tilted significantly and there is a risk of tipping, the tipping protection mechanism 5 triggers the protection mechanism. The touch screen all-in-one machine 6 automatically controls the solenoid valve 503 to open the air passage, so that the high-pressure gas tanks 502 work. The high-pressure gas is quickly introduced into the folded airbags 506 in the groove 505 through the air supply pipe 504, so that the folded airbags 506 are quickly inflated and unfolded, forming a buffer protection structure from all sides of the platform 1 to offset the tipping impact. The top of the groove 505 is hinged with a movable plate 507. Under normal conditions, the movable plate 507 closes the opening of the groove 505 and covers the internal folded airbags 506 to ensure that the appearance of the booth is flat and beautiful. When the airbags are inflated and unfolded, they can automatically push open the movable plate 507 to complete the protective unfolding action without obstruction.

[0027] Furthermore, an audible and visual alarm 8 is installed on the stand 1. The audible and visual alarm 8 is electrically connected to the touch screen all-in-one machine 6. When the tilt sensor 13 detects that the support platform 3 or the stand 1 is tilted beyond the tolerance and there is a risk of tipping over, the touch screen all-in-one machine 6 will immediately trigger the audible and visual alarm 8 to work, and issue a warning prompt through sound and light at the same time, so as to promptly remind the staff to check the status of the booth and adjust the placement.

[0028] To prevent the high-pressure gas tank 502 from being damaged by external impacts, dust corrosion, or accidental human contact, a housing 501 is fixedly connected to the bottom of the platform 1. The high-pressure gas tank 502 is located inside the housing 501, and the housing 501 protects the high-pressure gas tank 502.

[0029] like Figure 2 As shown, four wheels 9 are symmetrically installed at the bottom of the platform 1, and four legs 12 are symmetrically threaded at the bottom of the platform 1. The wheels 9 facilitate the flexible movement, transportation and position adjustment of the entire platform. At the same time, the legs 12 can provide ground support for the platform 1 by adjusting the installation height and lifting the wheels 9 off the ground.

[0030] Specifically, the bottom of the support plate 2 is fixedly connected with a reinforcing rib 11, which strengthens the support plate 2 and improves the overall structural strength and load-bearing stability of the platform 1.

[0031] Based on the above technical solution, the working steps of this solution are summarized as follows: When this application is used, the support platform 3 inside the frame 1 is used to place the exhibits, the touch screen all-in-one machine 6 is the control terminal, and the tilt sensor 13 collects the tilt data of the support platform 3 and the frame 1 in real time and transmits the electrical signal to the touch screen all-in-one machine 6.

[0032] When in use, the horizontal adjustment mechanism 4 is supported by two symmetrical U-shaped brackets 401 on the top of the support plate 2. The motor 406 can drive the bidirectional threaded rod 407 to rotate in both directions, causing the hinged ends of the first connecting rod 403 and the second connecting rod 404 to move along the direction of the bidirectional threaded rod 407. This causes the second U-shaped plate 405 and the connecting sleeve 409 to move up and down, changing the tilt state of both ends of the support platform 3. Combined with the horizontal monitoring data of the tilt sensor 13, the horizontal adjustment of the support platform 3 is completed until the monitored horizontal data is stable, and the horizontal calibration is completed. The tilt protection mechanism 5 is supplied with air by four high-pressure air tanks 502 around the bottom of the frame 1. The solenoid valve 503 controls the opening and closing of the air supply pipe 504 to inflate the folded airbag 506 in the groove 505.

[0033] When the tilt sensor 13 detects that the stand 1 is tilted significantly and there is a risk of tipping over, the tipping protection mechanism 5 triggers the protection mechanism. The touch screen all-in-one machine 6 automatically controls the solenoid valve 503 to open the air circuit, so that the high-pressure gas tank 502 works. The high-pressure gas is quickly introduced into the folded airbag 506 in the groove 505 through the gas supply pipe 504, so that the folded airbag 506 is quickly inflated and unfolded, forming a buffer protection structure from all sides of the stand 1 to offset the tipping impact force, effectively preventing the booth from tipping over and damaging the exhibits, and ensuring the safety of the exhibition in all aspects.
