Description

Technical Field

[0001] The invention relates to the field of cultural relics protection, in particular to an air pressure regulating device for cultural relics protection. Background Art

[0002] At present, for the protection of cultural relics, especially those of smaller size, they are generally placed in glass covers. This not only isolates the cultural relics from the outside world and protects them, but also makes it convenient to view the cultural relics through the glass for exhibition. At the same time, in order to prevent the cultural relics from being oxidized by contact with air, protective inert gas needs to be injected into the glass cover.

[0003] However, the above-mentioned protection measures still have certain defects. For example, when the temperature changes, the gas in the glass cover is affected by thermal expansion and contraction, which may cause the air pressure inside the glass cover to increase or decrease in a closed and solid space, thus affecting the cultural relics. When cultural relics need to be transported to another place for exhibition, changes in the region and altitude will cause a large pressure difference between the outside air pressure and the air pressure inside the glass cover. When there is a pressure difference between the inside and outside, the sudden large change in air pressure will cause damage to the cultural relics when taking and placing the cultural relics. Summary of the invention

[0004] In view of the shortcomings of the prior art, the present invention provides an air pressure regulating device for protecting cultural relics, which solves the problem of cultural relics being damaged by air pressure. At the same time, with the support mechanism and the folding mechanism, the entire device can be used for daily exhibitions and for the transportation of cultural relics. With the cushioning of the airbag, the protection of cultural relics from impact is further achieved.

[0005] To achieve the above purpose, the present invention is implemented through the following technical solutions: an air pressure regulating device for cultural relics protection, including a glass display cabinet, the glass display cabinet is a sealed structure, the interior of which is used to place cultural relics, and the bottom end of the glass display cabinet is provided with a valve valve connected with the interior thereof, the glass display cabinet is embedded in and fixedly connected to a protective frame, the inner bottom of the protective frame is provided with a cavity, an air pipe is provided in the cavity, the parallel ends of the air pipes are fixedly connected and communicated with the valve valve, the branch ends of the air pipes respectively penetrate the bottom of the protective frame and are provided with electric pressure reducing valves at the ports, the other ports of the electric pressure reducing valves are fixedly connected and communicated with the pipes for air inlet and outlet of the air bag through quick-connect connectors, the air bag is made of non-elastic material, and the internal gas volume is less than half of the air bag volume, the bottom side wall of the protective frame is provided with a folding mechanism, the folding mechanism is clamped with the air bag, and the bottom end of the protective frame is provided with a supporting mechanism.

[0008] Preferably, the limiting mechanism includes a limiting pin, which is slidably connected inside the second side plate and passes through the side wall of the second side plate. At the same time, the limiting end of the limiting pin is inserted into the limiting hole of the first side plate, and the two limiting pins located on the same second side plate are fixedly connected by a spring.

[0009] Preferably, the side walls opposite to each other of the two second side panels are each provided with a cover plate, which covers the outside of the limit pin, and one end of which is rotatably connected to the lower end of the second side panel, and the other end is fixedly connected to a latch lock and coupled with a lock buckle on the surface of the second side panel.

[0013] Working principle: The glass showcase is connected to the airbag to make the internal air pressure of the two equal. The glass showcase is a container with a fixed volume, and the airbag is a container with a variable volume. In this way, the airbag is used as a bridge to link the air pressure inside the glass showcase with the external air pressure, which not only achieves the isolation of the gas inside the glass showcase from the outside world, but also facilitates the balance of air pressure with the outside world. The electric pressure reducing valve is used to limit the gas flow rate between the glass showcase and the airbag, thereby avoiding the damage of cultural relics caused by violent airflow due to excessive pressure difference. The air pressure detector is used to detect the air pressure on both sides of the valve. When the air pressure in the glass showcase is too high or too low and close to the critical value, the electric pressure reducing valve is completely closed to disconnect the gas flow between the glass showcase and the airbag, thereby avoiding further changes in the air pressure in the glass showcase that exceed the tolerance limit of the cultural relics and cause damage to the cultural relics.

[0014] The present invention provides an air pressure regulating device for cultural relics protection, which has the following beneficial effects:

[0015] 1. The present invention connects the glass display case with the airbag to make the internal air pressure of the two equal. The glass display case is a container with a fixed volume, and the airbag is a container with a variable volume. In this way, the airbag is used as a bridge to link the air pressure in the glass display case with the external air pressure, which not only realizes the isolation of the gas in the glass display case from the outside, but also facilitates the balance of air pressure with the outside, thereby avoiding the problem of damage to cultural relics caused by pressure changes in the glass cover, and at the same time avoiding the problem of damage to cultural relics caused by instantaneous large pressure changes when taking and placing cultural relics when there is an internal and external pressure difference. At the same time, the electric pressure reducing valve is used to limit the gas flow rate between the glass display case and the airbag, thereby avoiding the damage to cultural relics caused by violent airflow due to excessive pressure difference. The air pressure detector is used to detect the air pressure on both sides of the valve, thereby avoiding the problem of damage to cultural relics caused by excessively high or low air pressure in the glass display case exceeding the bearing limit of the cultural relics.

At the same time, with the cushioning of the airbag, it further protects the cultural relics from being hit during transportation. BRIEF DESCRIPTION OF THE DRAWINGS

Implementation

[0022] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0023] Please see attached Figure 1 -Attached Figure 4The embodiment of the present invention provides an air pressure regulating device for protecting cultural relics, including a glass display case 1. The glass display case 1 is a sealed structure, and its interior is used to place cultural relics. The bottom of the glass display case 1 is provided with a valve valve 101 connected with the interior thereof. The glass display case 1 is embedded in and fixedly connected to a protective frame 2. A cavity 201 is provided at the inner bottom of the protective frame 2. An air pipe 3 is provided in the cavity 201. The parallel ends of the air pipe 3 are fixedly connected and connected with the valve valve 101. The branch ends of the air pipe 3 respectively penetrate the bottom of the protective frame 2 and are provided with electric pressure reducing valves 4 at the ports. The other ports of the electric pressure reducing valves 4 are fixedly connected and connected with the pipelines for air inlet and outlet of the air bag 5 through quick-connect joints. The air bag 5 is made of non-elastic material, and the gas volume inside it is less than half of the volume of the air bag 5. A folding mechanism is provided on the side wall at the bottom of the protective frame 2. The folding mechanism is clamped with the air bag 5. A supporting mechanism is provided at the bottom of the protective frame 2.

[0024] The glass display case 1 is connected with the air bag 5 to make the internal air pressure of the two equal. The glass display case is a container with a fixed volume, and the air bag is a container with a variable volume. In this way, the air bag is used as a bridge to link the air pressure in the glass display case with the external air pressure, which not only realizes the isolation of the gas in the glass display case from the outside, but also facilitates the balance of air pressure with the outside, thereby avoiding the problem of damage to cultural relics caused by changes in air pressure in the glass cover, and at the same time avoiding the problem of damage to cultural relics caused by instantaneous large air pressure changes when taking and placing cultural relics when there is an internal and external pressure difference. At the same time, the electric pressure reducing valve is used to limit the gas flow rate between the glass display case and the air bag, thereby avoiding the damage to cultural relics caused by violent airflow due to excessive pressure difference.

[0025] An air pressure detector is disposed inside the valve 101 , and the air pressure detector is used to monitor the air pressure on both sides of the valve 101 .

[0026] The air pressure detector is used to detect the air pressure on both sides of the valve 101, so as to avoid the problem that the air pressure in the glass display case 1 is too high or too low and exceeds the tolerance limit of the cultural relics, thus causing damage to the cultural relics.

[0027] The folding mechanism includes a first side panel 6 and a second side panel 7. The two first side panels 6 are symmetrically arranged, and their shaft ends are slidably and rotatably connected to the two symmetrical side walls at the bottom of the protective frame 2. The two second side panels 7 are symmetrically arranged, and their shaft ends are slidably and rotatably connected to the other two symmetrical side walls at the bottom of the protective frame 2. A limiting mechanism is arranged between the first side panel 6 and the second side panel 7, and the opposite surfaces of the first side panel 6 and the second side panel 7 are both clamped with the base end of the airbag 5.

[0028] By setting the first side panel 6 and the second side panel 7, when exhibition is required, the first side panel 6 and the second side panel 7 are unfolded to the lower part of the device, and then connected by the limiting mechanism to form a booth; when transportation is required, the first side panel 6 and the second side panel 7 are turned up to the upper part of the device, and connected by the limiting mechanism to cover and wrap the glass display case 1, thereby protecting the glass display case 1. At the same time, the airbag 5 is at the outermost side at this time, so when it is hit during transportation, the airbag 5 plays a buffering role, further improving the protection effect.

[0029] The limiting mechanism includes a limiting pin 8, which is slidably connected to the inside of the second side plate 7 and passes through the side wall of the second side plate 7. At the same time, the limiting end of the limiting pin 8 is inserted into the limiting hole of the first side plate 6. The two limiting pins 8 located on the same second side plate 7 are fixedly connected by a spring 9.

[0030] Pull the buckles on the two limit pins 8 to bring the two limit pins 8 closer to each other, then the limit pins 8 will slide out of the limit holes of the first side plate 6, and the second side plate 7 can be separated from the first side plate 6. When fixed limit is required, first bring the first side plate 6 and the second side plate 7 together, and then release the limit pins 8. Under the elastic action of the spring 9, the two limit pins 8 move away from each other, and the limit pins 8 are inserted into the limit holes of the first side plate 6, so that a limit fixation is formed between the first side plate 6 and the second side plate 7.

[0031] The side walls opposite to each other of the two second side panels 7 are each provided with a cover plate 10, which covers the outside of the limit pin 8, and one end of the cover plate 10 is rotatably connected to the lower end of the second side panel 7, and the other end is fixedly connected to a latch lock 11 and coupled to a lock buckle 12 on the surface of the second side panel 7.

[0032] The cover plate 10 serves to cover the limiting mechanism. At the same time, due to the configuration of the latch lock 11 and the lock catch 12, others cannot use the limiting mechanism to open the side panel without a key, thus playing a protective role.

[0033] An illumination device is provided in the upper part of the protection frame 2 for supplementing light to the glass display case 1 .

[0034] Auxiliary lighting for exhibitions is achieved through lighting devices.

[0035] A handle 13 is fixedly connected to the upper wall of the protection frame 2 , and lock buckles 12 are fixedly connected to both sides of the handle 13 , and their positions correspond to the latch locks 11 .

[0036] When the device is in the transport state, the first side panel 6 and the second side panel 7 are both flipped up to block the glass display case 1, and the cover plate 10 on the second side panel 7 is connected and fixed with the lock buckle 12 on the handle 13 through the latch lock 11, thereby achieving the purpose of strengthening the fixation, and a key is required to open it, further increasing the protection effect.

[0037] The supporting mechanism comprises a lifting rod 14, the output end of the lifting rod 14 is fixedly connected to the bottom end of the protection frame 2, and the base end of the lifting rod 14 is fixedly connected to a base 15 with self-locking wheels.

[0038] The setting of the lifting rod 14 allows the device to be raised to support and stabilize the entire device when it is in the exhibition state, avoiding the weak supporting force caused by simply using the first side panel 6 and the second side panel 7 as support, and at the same time facilitates the flipping of the first side panel 6 and the second side panel 7 when the device is converted between the two forms; when the device is in the transportation state, the lifting rod 14 is lowered to lower the overall center of gravity, thereby ensuring the stability of the placement. At the same time, the setting of the self-locking wheels makes it portable and labor-saving when moved by manpower.

[0039] Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that various changes, modifications, substitutions and variations may be made to the embodiments without departing from the principles and spirit of the present invention, and that the scope of the present invention is defined by the appended claims and their equivalents.
