Description

Technical Field

[0001] This invention belongs to the field of shockproof cultural relic rack technology, and in particular relates to an intelligent fixed shockproof cultural relic rack. Background Technology

[0002] Cultural relics are generally stored or displayed on special cultural relic shelves. These shelves need to be designed to protect the relics, such as being earthquake-resistant and impact-resistant.

[0003] Currently, the most effective earthquake-resistant artifact racks utilize airbags for protection, but the following issues still exist:

[0004] First, when a large vibration occurs, the airbag can inflate quickly. However, in order to achieve rapid inflation, the inflation pressure is relatively high, which may cause the airbag to damage the cultural relic. If the pressure is reduced, the inflation speed will be very slow, and it will not be able to protect the cultural relic quickly.

[0005] Secondly, the protection provided by inflatable airbags is generally one-time use and cannot be reused.

[0006] Third, specific airbags protect artifacts of specific sizes and shapes. If the size of the artifact is not suitable, the airbags cannot protect small artifacts or break large artifacts.

[0007] This invention designs an intelligent fixed shockproof cultural relic rack to solve the above problems. Summary of the Invention

[0008] To achieve the above objectives, the present invention employs the following technical solutions:

[0009] An intelligent fixed shockproof artifact rack includes a protective cover, a gas generator, lateral protective airbags, a bottom protective airbag, a mounting support, a first one-way valve, a second one-way valve, a first valve, a second valve, and a sliding shell. The protective cover is a square glass enclosure, with the mounting support fixedly installed on its inner bottom surface. The upper end of the mounting support has a disc-shaped protrusion with a concave circular mounting groove on its upper surface. The bottom protective airbag has a spiral structure with a sliding shell fixedly installed at its lower end. The bottom protective airbag is mounted within the circular mounting groove via the sliding shell, and the sliding shell and the circular mounting groove are connected by a guide block and a guide groove. The artifact is placed on the upper side of the bottom protective airbag. A lateral protective airbag is installed on each of the four inner sidewalls of the protective cover. A second elastic strip is installed on one side of the lateral protective airbag; during normal display, the lateral protective airbag is shaped like a snail and located on the lower side of the artifact under the action of the second elastic strip; the lateral protective airbag is divided into two parts: a first airflow channel and a second airflow channel. At the junction of the inner ends of the first and second airflow channels, there is a second valve that can only be opened towards the second airflow channel, and a leaf spring is installed between the second valve and the second airflow channel; at the junction of the outer ends of the first and second airflow channels, there is a first valve that can only be opened towards the first airflow channel; protective airbags that communicate with the second airflow channel are evenly distributed on the side wall of the second airflow channel; the inner end of the bottom protective airbag has an air outlet, and a fourth one-way valve is installed on the air outlet.

[0010] The gas generator is installed on the lower side of the protective cover, and the output end of the gas generator is connected to the bottom of the four side protective airbags; the outer end of each second airflow channel is connected to the inner groove on the disc-shaped protrusion through a second connecting air pipe; a first one-way valve is installed on the second connecting air pipe; a first connecting air pipe is connected to each second connecting air pipe, and the two ends of the first connecting air pipe are located on both sides of the corresponding first one-way valve; a second one-way valve is installed on each second connecting air pipe.

[0011] As a preferred embodiment, a sensor is fixedly installed on the inner bottom surface of the protective cover, and the sensor and the gas generator are connected by a connector.

[0012] As a preferred embodiment, the lower side wall of the protective cover has an installation cavity, and a door is swaying at the outlet of the installation cavity; the gas generator is installed in the installation cavity, and a handle is installed on the gas generator.

[0013] As a preferred embodiment, the inner wall of the lower side of the protective cover has a square air cavity; the lower end of the first airflow channel of the four lateral protective airbags is connected to the upper side of the air cavity; the square air cavity communicates with the mounting cavity.

[0014] As a preferred embodiment, a first elastic strip is fixedly installed on the side wall of the bottom protective airbag.

[0015] As a preferred embodiment, the fourth one-way valve and the first one-way valve have identical structures. The first one-way valve includes a first valve plug, a first valve body, a second spring, a limiting assembly, a damping rod, a third spring, a trigger rod, a sealing sleeve, a trigger ramp, and a fourth spring. The first valve body is fixedly mounted on the second connecting air pipe and has an annular sealing cavity. The first valve plug is slidably mounted inside the first valve body, and a second spring is installed between the first valve plug and the first valve body. One end of the sealing sleeve has an annular groove, and the sealing sleeve is slidably mounted inside the first valve body. The other end of the sealing sleeve mates with the sealing cavity. A third spring and multiple circumferentially evenly distributed damping rods are installed between the sealing sleeve and the first valve body. The limiting assembly is slidably mounted inside the first valve body, and a fourth spring is installed between the limiting assembly and the first valve body. The limiting assembly mates with the groove on the sealing sleeve. The limiting assembly has a trigger ramp, and a trigger rod is fixedly mounted on the first valve plug, with the trigger rod mates with the trigger ramp.

[0016] As a preferred embodiment, a first guide telescopic rod is installed between the limiting component and the first valve housing, and the first guide telescopic rod is located in the middle of the fourth spring.

[0017] As a preferred embodiment, a reset pressure rod is fixedly installed on the sealing sleeve.

[0018] As a preferred embodiment, the second check valve includes a second valve plug, a second valve housing, a second guide telescopic rod, and a fifth spring.

[0019] As a preferred embodiment, an easily tearable film is installed inside the protective cover on the upper side of the lateral protective airbag.

[0020] Compared with existing technologies, the advantages of this invention are:

[0021] 1. The present invention is equipped with pressure relief valves on the side protective airbags and the bottom protective airbags. The pressure relief valves can ensure that the airflow pressure in the side protective airbags and the bottom protective airbags meets the protection function of the cultural relics without causing damage to the cultural relics due to excessive pressure.

[0022] 2. The protective airbags installed on the second airflow channel will press against the outer surface of the artifact during the opening process. The opening range of the protective airbags can be adjusted according to the size of the artifact, and the airflow pressure in each protective airbag is basically equal.

[0023] 3. The device designed in this invention can be reused. When releasing gas, the door is opened and the gas generator is taken out. The installation cavity and the square air cavity will then be connected. Since there is no airflow injected into the first airflow channel at this time, the air pressure in the first airflow channel is less than the air pressure in the second airflow channel. Therefore, under the action of the second elastic strip, the gas in the lateral protective airbag will flow out from the first valve; while the gas in the bottom protective airbag will flow into the second airflow channel from the second one-way valve and finally be discharged.

[0046] The specific embodiments of the present invention will be described in further detail below with reference to the accompanying drawings and examples. The following embodiments and drawings are used to illustrate the present invention, but are not intended to limit the scope of the invention.

[0047] Three intelligent, fixed, earthquake-resistant cultural relics, such as Figure 1 As shown, it includes a protective cover 1, a gas generator 2, a side protective airbag 4, a bottom protective airbag 14, a mounting support 15, a first one-way valve 12, a second one-way valve 13, a first valve 47, a second valve 48, and a sliding shell 16, wherein... Figure 3As shown, the protective cover 1 is a square glass cover, and a square air cavity 9 is provided on the inner side wall of the lower side of the protective cover 1; a mounting cavity 10 is opened on the side wall at the lower end of the protective cover 1, and the square air cavity 9 communicates with the mounting cavity 10; a door 5 is sway-mounted at the outlet of the mounting cavity 10; as shown Figure 2 , 4 As shown in Figure 5, the gas generator 2 is installed inside the mounting cavity 10, and a handle 11 is installed on the gas generator 2; a sensor 8 is fixedly installed on the inner bottom surface of the protective cover 1, and the sensor 8 and the gas generator 2 are connected by a connector 6; a mounting support 15 is fixedly installed on the inner bottom surface of the protective cover 1, such as... Figure 1 , 6 As shown in Figure 7, the upper end of the mounting support 15 has a disc-shaped protrusion 17, and a concave circular mounting groove is formed on the upper surface of the disc-shaped protrusion 17; the bottom protective airbag 14 has a volute structure and a sliding shell 16 is fixedly installed at its lower end. The bottom protective airbag 14 is installed in the circular mounting groove through the sliding shell 16. The sliding shell 16 and the circular mounting groove are connected by the cooperation of a guide block and a guide groove, as shown in Figure 7. Figure 8 , 9 As shown, a first elastic strip 19 is fixedly installed on the side wall of the bottom protective airbag 14; the artifact 3 is placed on the upper side of the bottom protective airbag 14; as Figure 1 , 6 As shown, a lateral protective airbag 4 is installed on each of the four inner walls of the protective cover 1, and the lower end of the first airflow channel 22 of the four lateral protective airbags 4 is connected to the upper side of the air chamber 9; as Figure 17 , 18 As shown in Figure 19, a second elastic strip 44 is installed on one side of the lateral protective airbag 4; as Figure 20 As shown in Figure a, during normal display, the lateral protective airbag 4 forms a snail shape under the action of the second elastic strip 44 and is located below the artifact 3; as shown in Figure a. Figure 18 , 19 As shown, the lateral protective airbag 4 is divided into two parts: a first airflow channel 22 and a second airflow channel 43. At the junction of the inner ends of the first airflow channel 22 and the second airflow channel 43, there is a second valve 48 that can only be opened towards the second airflow channel 43. A leaf spring 49 is installed between the second valve 48 and the second airflow channel 43. At the junction of the outer ends of the first airflow channel 22 and the second airflow channel 43, there is a first valve 47 that can only be opened towards the first airflow channel 22. Protective airbags 42, evenly distributed and communicating with the second airflow channel 43, are installed on its sidewall. Figure 8 , 9 As shown, the inner end of the bottom protective airbag 14 has an air outlet, and a fourth one-way valve 45 is installed on the air outlet.

[0048] In this invention, the protective cover 1 is a transparent, shatterproof, and theft-proof glass cover, which facilitates viewing of the cultural relic 3.

[0049] The gas generator 2 contains an azide compound, which generates a large amount of gas upon activation. After generating the gas, the gas generator 2 releases it into the square gas chamber 9, and the gas entering the square gas chamber 9 enters the lateral protective airbag 4. In this invention, the gas generator 2 is placed in the mounting cavity 10, and a door 5 is installed at the outlet of the mounting cavity 10, allowing the gas generator 2 to be replaced after use. In this invention, a handle 11 is installed on the side wall of the gas generator 2, which facilitates the placement and removal of the gas generator 2.

[0050] In this invention, a sensor 8 is installed at the bottom of the protective cover 1. The sensor 8 is connected to the gas generator 2 via a detachable connector 6. After sensing vibration, the sensor 8 transmits an electrical signal to the gas generator 2. The temperature of the gas generator 2 increases, causing the azide compound inside to trigger the generation of gas that enters the square gas chamber 9. The outlet of the gas generator 2 is a conical surface, which facilitates the ejection of gas. When replacing the gas generator 2, the detachable connector 6 between the gas generator 2 and the sensor 8 is disconnected. After replacement, the new gas generator 2 and the sensor 8 are connected again via the detachable connector 6. The detachable connector 6 is provided for convenient replacement of the gas generator 2.

[0051] like Figure 21 As shown in Figure a, during normal display, the sliding shell 16 is located at the bottom of the circular mounting groove on the disc-shaped protrusion 17. The bottom protective airbag 14 is compressed and embedded in the circular mounting groove under the action of the first elastic strip 19. At this time, the bottom of the artifact 3 is supported on the disc-shaped protrusion 17. After vibration, the gas entering the lateral protective airbag 4 will enter the circular mounting groove through the second connecting air pipe 21, and then enter the sliding shell 16. However, since the bottom protective airbag 14 is embedded in the circular mounting groove at this time, it cannot be released circumferentially. Therefore, the gas entering the circular mounting groove will first push the sliding shell 16 upward. The movement of the sliding shell 16 will drive the bottom protective airbag 14 to move. During the upward movement of the bottom protective airbag 14, when it contacts the bottom of the artifact 3, the bottom protective airbag 14 acts as a support for the bottom of the artifact 3. When the bottom protective airbag 14 completely slides out of the circular mounting groove, the sliding shell 16 also moves to the limit state of the cooperation between the guide block and the guide groove. At this time, the gas entering the sliding shell 16 will enter the bottom protective airbag 14, as shown in Figure a. Figure 21 As shown in b, the bottom protective airbag 14 is released and deployed in a circumferential manner, providing support and protection for the bottom of artifact 3.

[0052] like Figure 20As shown in Figure a, during normal display, the lateral protective airbag 4 is shaped like a snail and located below the artifact 3 under the action of the second elastic strip 44. When vibration occurs, the sensor 8 detects the vibration and transmits a signal to the gas generator 2. The gas generator 2 generates gas and releases it into the square air chamber 9. The gas entering the square air chamber 9 flows into the first airflow channel 22. Because a leaf spring 49 is installed between the second valve 48 and the second airflow channel 43, forming a one-way valve, the gas entering the first airflow channel 22 will first fill the first airflow channel 22. During the filling process, as... Figure 20 As shown in b, the lateral protective airbag 4 will be released and expanded; however, since there is no gas in the second airflow channel 43 at this time, the protective airbag 42 installed on the second airflow channel 43 will not be opened. This design ensures that the protective airbag 42 installed on the second airflow channel 43 will not be opened simultaneously during the upward release and opening of the lateral protective airbag 4, thus preventing the artifact 3 from being pushed over; when the gas in the first airflow channel 22 is full and its pressure is sufficient to open the second valve 48, the gas in the first airflow channel 22 will enter the second airflow channel 43 from the second valve 48, and the gas entering the second airflow channel 43 will enter the protective airbag 42 installed on it, causing the protective airbag 42 to open and wrap around the side of the artifact 3; during this process, because there is always gas flow in the first airflow channel 22 and the flow pressure is greater than the airflow pressure in the second airflow channel 43, the first valve 47 is in a closed state during this process and will not affect the flow of air. Therefore, during the process, the protective airbag 42 installed on the second airflow channel 43 will press against the outer surface of the artifact 3 when it is opened. The opening range of the protective airbag 42 can be adjusted according to the size of the artifact 3, and the airflow pressure in each protective airbag 42 is basically equal.

[0053] like Figure 10 As shown, the outer end of each second airflow channel 43 is connected to the inner groove on the disc-shaped protrusion 17 through a second connecting air pipe 21; a first one-way valve 12 is installed on the second connecting air pipe 21; a first connecting air pipe 20 is connected to each second connecting air pipe 21, and the two ends of the first connecting air pipe 20 are located on both sides of the corresponding first one-way valve 12; a second one-way valve 13 is installed on each second connecting air pipe 21.

[0054] The fourth check valve 45 and the first check valve 12 have the same structure, such as Figure 11 , 12As shown, the first one-way valve 12 includes a first valve plug 23, a first valve housing 25, a second spring 26, a limiting assembly 27, a damping rod 28, a third spring 29, a trigger rod 30, a sealing sleeve 31, a trigger ramp 35, and a fourth spring 37. The first valve housing 25 is fixedly mounted on the second connecting air pipe 21. Figure 13 As shown, the first valve housing 25 has an annular sealing cavity 32; as Figure 12 , 14 As shown, the first valve plug 23 is slidably installed inside the first valve housing 25, and a second spring 26 is installed between the first valve plug 23 and the first valve housing 25; one end of the sealing sleeve 31 has an annular groove 34, and the sealing sleeve 31 is slidably installed inside the first valve housing 25, while the other end of the sealing sleeve 31 mates with the sealing cavity 32; a third spring 29 and a plurality of circumferentially evenly distributed damping rods 28 are installed between the sealing sleeve 31 and the first valve housing 25; Figure 15 As shown, the limiting component 27 is slidably installed inside the first valve housing 25, and a fourth spring 37 is installed between the limiting component 27 and the first valve housing 25; a first guide telescopic rod 36 is installed between the limiting component 27 and the first valve housing 25, and the first guide telescopic rod 36 is located in the middle of the fourth spring 37; the limiting component 27 cooperates with the slot 34 on the sealing sleeve 31; the limiting component 27 has a trigger ramp 35, and a trigger rod 30 is fixedly installed on the first valve plug 23, and the trigger rod 30 cooperates with the trigger ramp 35; a reset pressure rod 46 is fixedly installed on the sealing sleeve 31.

[0055] As the airflow entering the second airflow channel 43 increases, the gas pressure within the second airflow channel 43 continuously strengthens. When the airflow pressure in the second airflow channel 43 exceeds the elastic force between the second springs 26, the first valve plug 23 in the first one-way valve 12 slides relative to the first valve shell 25, causing the second connecting air pipe 21 to connect. At this time, the gas in the second airflow channel 43 flows into the circular mounting groove at the upper end of the disc-shaped protrusion 17 through the second connecting air pipe 21. That is, the fourth one-way valve 45 and the first one-way valve 12 designed in this invention are equivalent to a pressure relief valve, ensuring that the air pressure in the lateral protective airbag 4 and the bottom protective airbag 14 is sufficient to protect the cultural relic 3 without being too high and causing damage to the cultural relic 3. However, the gas generator 2 of this invention generates gas at a relatively fast speed, which can quickly protect the cultural relic 3. The gas entering the circular mounting groove will cause the bottom protective airbag 14 to open. During this process, the air pressure in the second airflow channel 43 will gradually increase, and the sliding range of the first valve plug 23 relative to the first valve shell 25 will gradually increase. The sliding of the first valve plug 23 will drive the trigger rod 30 to move. When the trigger rod 30 contacts the trigger inclined plate 35, the movement of the trigger rod 30 will squeeze the trigger inclined plate 35, causing the trigger inclined plate 35 to drive the limiting component 27 to slide. When the limiting component 27 is completely disengaged from the slot 34 on the sealing sleeve 31, the sealing sleeve 31 will slide into the sealing cavity 32 under the action of the third spring 29 to close the second connecting air pipe 21.

[0056] In this invention, the damping rod 28 delays the closing of the sealing sleeve 31. To achieve rapid protection of the cultural relic 3, the azide compound designed in this invention has a relatively short opening time for the first one-way valve 12 and the fourth one-way valve 45, and a relatively short interval between the opening of the first valve plug 23 and the triggering of the limiting component 27. However, in order to ensure that the gas passing through the first one-way valve 12 has time to enter the bottom protective airbag 14, the damping rod 28 is provided. The damping rod 28 delays the closing of the sealing sleeve 31, but this delay only ensures that the bottom protective airbag 14 can open smoothly to protect the cultural relic 3, and it will not be too long.

[0057] The function of the reset lever 46 is to reset the sealing sleeve 31. The sealing sleeve 31 can be reset by manually pulling the reset lever 46.

[0058] like Figure 16 As shown, the second one-way valve 13 includes a second valve plug 38, a second valve housing 39, a second guide telescopic rod 40, and a fifth spring 41. The second valve housing 39 is fixedly installed on the second connecting pipe. The second valve plug 38 is slidably installed inside the second valve housing 39 through the circumferentially evenly distributed second guide telescopic rods 40. The fifth spring 41 is installed between the second valve plug 38 and the second valve housing 39.

[0059] The device designed in this invention can be reused. When releasing gas, the gas generator 2 is taken out by opening the door 5, and the mounting cavity 10 and the square air cavity 9 will be connected. Since there is no airflow injected into the first airflow channel 22 at this time, the air pressure in the first airflow channel 22 is less than the air pressure in the second airflow channel 43. Therefore, under the action of the second elastic strip 44, the gas in the lateral protective airbag 4 will flow out from the first valve 47; while the gas in the bottom protective airbag 14 will flow into the second airflow channel 43 from the second one-way valve 13 and finally be discharged.

[0060] An easily tearable film is installed inside the protective cover, above the lateral protective airbag.

[0061] The above description is merely a preferred embodiment of the present invention and is not intended to limit the present invention in any way. Any simple modifications or equivalent changes made to the above embodiments based on the technical essence of the present invention shall fall within the protection scope of the present invention.

[0062] Implementation: When the device designed in this invention is used, when vibration occurs, the sensor 8 senses the vibration and transmits an electric current signal to the gas generator 2. The temperature of the gas generator 2 increases, causing the azide compound inside it to trigger the generation of gas that enters the square gas chamber 9. The gas entering the square gas chamber 9 flows into the first airflow channel 22. Because a leaf spring 49 is installed between the second valve 48 and the second airflow channel 43, the second valve 48 and the leaf spring 49 form a one-way valve. Therefore, the gas entering the first airflow channel 22 will first fill the first airflow channel 22. During the filling process, the lateral protective airbag 4 will be released and expanded. However, since there is no gas in the second airflow channel 43 at this time, the protective airbag 42 installed on the second airflow channel 43 will not be opened. This design ensures that the protective airbag 42 installed on the second airflow channel 43 will not be opened at the same time as the lateral protective airbag 4 is released and opened upward, thus preventing the artifact 3 from being pushed over. When the gas in the first airflow channel 22 is full and its pressure is sufficient to open the second valve 48, the gas in the first airflow channel 22 will enter the second airflow channel 43 from the second valve 48. The gas entering the second airflow channel 43 will then enter the protective airbag 42 installed on it, causing the protective airbag 42 to open and wrap around the side of the artifact 3.

[0063] As the airflow entering the second airflow channel 43 increases, the gas pressure within the channel increases. When the pressure exceeds the elastic force between the second springs 26, the first valve plug 23 in the first one-way valve 12 slides relative to the first valve shell 25, connecting the second connecting air pipe 21. At this point, the gas in the second airflow channel 43 flows through the second connecting air pipe 21 into the circular mounting groove at the upper end of the disc-shaped protrusion 17, and then into the sliding shell 16. However, because the bottom protective airbag 14 is embedded in the circular mounting groove and cannot be released circumferentially, the gas entering the circular mounting groove first pushes the sliding shell 16 upwards. The movement of the sliding shell 16 then moves the bottom protective airbag. 14. During the upward movement of the bottom protective airbag 14, when it comes into contact with the bottom of the artifact 3, the bottom protective airbag 14 acts as a support for the bottom of the artifact 3. When the bottom protective airbag 14 slides completely out of the circular mounting groove, the sliding shell 16 also moves to the limit state of the cooperation between the guide block and the guide groove. At this time, the gas entering the sliding shell 16 will enter the bottom protective airbag 14, causing the bottom protective airbag 14 to release and expand circumferentially, providing support and protection for the bottom of the artifact 3. When the air pressure in the bottom protective airbag 14 reaches the pressure at which the fourth one-way valve 45 opens, the fourth one-way valve 45 opens to release pressure, ensuring that the airflow pressure of the bottom protective airbag 14 is not too high after satisfying the support of the bottom of the artifact 3, thus not causing damage to the artifact 3.

[0064] When releasing gas, open door 5 to remove gas generator 2, and the mounting cavity 10 and square air cavity 9 will be connected. Since there is no airflow injected into the first airflow channel 22 at this time, the air pressure in the first airflow channel 22 is less than the air pressure in the second airflow channel 43. Therefore, under the action of the second elastic strip 44, the gas in the lateral protective airbag 4 will flow out from the first valve 47; while the gas in the bottom protective airbag 14 will flow into the second airflow channel 43 from the second one-way valve 13 and finally be discharged.
