Description

Technical Field

[0001] The utility model belongs to the technical field of cultural relic protection boxes, in particular to a protection box for museum cultural relics transfer. Background Art

[0002] Cultural relics are artifacts or remains of historical, artistic, and scientific value left behind by humanity through social activities. They are part of the past and cannot be recreated, so they are generally preserved in museums. Sometimes, museum artifacts need to be transported elsewhere for exhibition or teaching purposes. During this process, museum artifacts are often packed in wooden or plastic crates. During transport, they can be subject to external impacts, with the impact force being transferred from the crate to the artifact, potentially causing damage. Furthermore, when placing artifacts in protective crates, the limited space makes it difficult to secure them. Utility Model Content

[0003] In order to solve the above-mentioned existing problems, the present invention provides a protective box for the transfer of museum cultural relics. It adopts the electromagnetic principle and is equipped with a magnetic resistance side protection component. The repulsive force between the first electromagnetic strip and the second electromagnetic strip due to the same poles repels each other to offset the external impact force, so that the collision plate does not collide with the lifting box when receiving the external impact force. At the same time, combined with the sliding connection structure, the current intensity flowing through the second electromagnetic strip is adjusted, so that the repulsive force between the first electromagnetic strip and the second electromagnetic strip can adapt to different external impact forces, thereby preventing the cultural relics from being damaged by impact. In addition, a split structure is adopted and a lifting-type bearing component is provided, which expands the operating space for fixing the cultural relics. After the cultural relics are initially fixed, they are placed in the lifting box and then fixed separately by the side wall airbags and the top airbags. The operation is convenient and the cultural relics are fully protected.

[0004] To achieve the above-mentioned purpose, the technical solution adopted by the present invention is as follows: The present invention provides a protective box for the transfer of museum cultural relics, including a lifting box, a box cover is rotatably provided on the upper part of the lifting box, a lock is provided between the box cover and the lifting box, protective grooves are respectively provided on the four sides of the outer side of the lifting box, a magnetic resistance side protection component is provided in the protective groove, and a lifting-type load-bearing component is provided in the lifting box, wherein the magnetic resistance side protection component includes an anti-collision mechanism, a first electromagnetic strip and a sliding connection mechanism, a plurality of the first electromagnetic strips are respectively embedded in the four sides of the bottom wall of the protective groove, the anti-collision mechanism is slidably arranged in the protective groove, and the sliding connection mechanism is connected between the center of the bottom wall of the protective groove and the anti-collision mechanism.

[0005] Furthermore, the anti-collision mechanism includes a collision plate, a buffer spring, a second electromagnetic strip and a resistor strip. The collision plate is slidably arranged in the protective groove. The buffer spring is connected between the collision plate and the bottom wall of the protective groove. Multiple buffer springs are respectively arranged at the four corners of the collision plate. The second electromagnetic strip and the resistor strip are respectively embedded in the side wall of the collision plate close to the suitcase. Multiple second electromagnetic strips are respectively arranged at the four sides of the collision plate. Multiple resistor strips are respectively arranged on the inner side of the second electromagnetic strip. The resistor strip is perpendicular to the second electromagnetic strip. One end of the resistor strip close to the second electromagnetic strip is electrically connected to the corresponding second electromagnetic strip. The buffer spring plays the role of elastic buffering and is distributed at the four corners of the collision plate. It is suitable for collisions in different directions.

[0006] Furthermore, the sliding connection mechanism includes a connecting rod, a follower block and a metal sheet, wherein a plurality of the connecting rods are rotatably arranged on the bottom wall of the protective groove, the movable ends of the plurality of connecting rods are respectively facing the resistor bar, the follower block is rotatably connected to the movable end of the connecting rod, the follower block is slidably arranged on the resistor bar, the metal sheet is embedded in the follower block, and the metal sheet and the resistor bar are slidably fitted;

[0007] Preferably, the projection of the second electromagnetic strip on the bottom wall of the protective groove coincides with the first electromagnetic strip. In an initial state, the follower block is located at the end of the resistor strip away from the second electromagnetic strip. The four first electromagnetic strips are connected in series via a wire. The metal sheet, the resistor strip, and the second electromagnetic strip facing in the same direction are connected in series to form an electrical circuit. The first electromagnetic strip and the second electromagnetic strip are arranged with the same polarity.

[0008] When in use, the first electromagnetic strip and the second electromagnetic strip are energized respectively to generate magnetism. Since the first electromagnetic strip and the second electromagnetic strip are arranged with the same pole, the electromagnetic repulsion force between the two prevents the collision plate from touching the bottom wall of the protective groove. In the initial state, the follower block is at the end of the resistor strip away from the second electromagnetic strip, that is, the resistance of the resistor strip connected to the electrical circuit of the metal sheet, the resistor strip and the second electromagnetic strip is at the maximum value, the current flowing through the second electromagnetic strip is at the minimum value, and the magnetism generated by the second electromagnetic strip is relatively small. When the outside of the suitcase encounters an external impact, it first hits the collision plate. After the impact, the collision plate approaches the bottom wall of the protective groove, and the buffer spring compresses The metal sheet slides on the resistance bar, and the length of the resistance bar in the electrical circuit connected to the metal sheet, the resistance bar, and the second electromagnetic bar decreases, thereby reducing the resistance value. This increases the current flowing through the second electromagnetic bar, strengthens the magnetism generated by the second electromagnetic bar, and increases the repulsive force between the first and second electromagnetic bars. The external impact force is offset by the magnetic field repulsion, thus protecting the suitcase from impact.

[0009] The greater the external impact force, the closer the collision plate is to the suitcase, the smaller the resistance value in the connected circuit, the greater the current intensity flowing through the second electromagnetic strip, and the greater the repulsive force between the first electromagnetic strip and the second electromagnetic strip. This achieves the technical effect of adjusting the electromagnetic strength of the second electromagnetic strip, thereby making the repulsive force between the first electromagnetic strip and the second electromagnetic strip adapt to the size of different external impact forces and protect cultural relics.

[0010] Furthermore, limiting slide grooves are respectively provided on the short sides of both sides of the suitcase, and the limiting slide grooves penetrate the inner wall of the suitcase.

[0014] When in use, the staff lifts the carrying handle upward, the return spring is compressed, the T-shaped carrying handle moves up in the lifting side plate, and then the draw rope is pulled up. Under the rotation transition of the transition wheel, the draw rope pulls the positioning block to retract into the contraction cavity, the extrusion spring is compressed, and the positioning block is free from the restriction of the first positioning slot. The entire lifting type bearing assembly is lifted, and the supporting plate moves up in the lifting box until the two sets of positioning blocks move to the corresponding second positioning slots. The carrying handle is released, and the carrying handle is reset under the elastic action of the return spring. The draw rope no longer pulls the positioning block. The positioning block pops out of the contraction cavity under the elastic action of the extrusion spring and engages with the second positioning slot, thereby fixing the position of the lifting type bearing assembly, and the supporting plate moves to the upper part of the lifting box, but does not separate from the lifting box. On the one hand, it is convenient for the placement and fixing operation of the cultural relics. On the other hand, the supporting plate is still within the protection range of the lifting box, avoiding the lifting type bearing assembly from separating from the lifting box and then needing to carry the cultural relics for a large range of movement, causing unpredictable damage.

[0035] like Figure 1 、 Figure 3 、 Figure 4 and Figure 5As shown, the magnetic resistance side protection assembly 2 includes an anti-collision mechanism 21, a first electromagnetic strip 22 and a sliding connection mechanism 23. The plurality of first electromagnetic strips 22 are respectively embedded in the four sides of the bottom wall of the protection groove 11. The anti-collision mechanism 21 is slidably arranged in the protection groove 11. The sliding connection mechanism 23 is connected between the center of the bottom wall of the protection groove 11 and the anti-collision mechanism 21.

[0036] Among them, the anti-collision mechanism 21 includes a collision plate 211, which is slidably arranged in the protective groove 11. A buffer spring 212 is connected between the collision plate 211 and the bottom wall of the protective groove 11. Multiple buffer springs 212 are respectively arranged at the four corners of the collision plate 211. A second electromagnetic strip 213 and a resistor strip 214 are respectively embedded on the side wall of the collision plate 211 close to the suitcase 1. Multiple second electromagnetic strips 213 are respectively arranged at the four sides of the collision plate 211, and multiple resistor strips 214 are respectively arranged on the inner side of the second electromagnetic strip 213.

In the initial state, the follower block 232 is located at the end of the resistor bar 214 away from the second electromagnetic strip 213. The four first electromagnetic strips 22 are connected in series via wires. The metal sheet 233, the resistor bar 214, and the second electromagnetic strip 213 facing in the same direction are connected in series to form an electrical circuit. The first electromagnetic strip 22 and the second electromagnetic strip 213 are arranged with the same polarity.

[0039] Working principle and workflow:

[0040] When in use, the lock buckle 5 is opened and the box cover 4 is opened. Then the staff pulls the lifting load-bearing assembly 3 out of the suitcase 1 through the pull ring 331; when pulling it out, the staff lifts the lifting handle 332 upward, the return spring 333 is compressed, and the T-shaped lifting handle 332 moves up in the lifting side plate 33, and then pulls the pull rope 334 up. Under the rotation transition of the transition wheel 337, the pull rope 334 pulls the positioning block 335 into the contraction cavity 336, the extrusion spring 338 is compressed, and the positioning block 335 is freed from the restriction of the first positioning groove 13. The entire lifting load-bearing assembly 3 is lifted, and the supporting plate 31 moves up in the suitcase 1 until the two sets of positioning blocks 335 move to the same position. At the corresponding second positioning groove 14, the lifting handle 332 is released, and the lifting handle 332 is reset under the elastic action of the return spring 333. The pull rope 334 no longer pulls the positioning block 335. The positioning block 335 pops out of the contraction cavity 336 under the elastic action of the extrusion spring 338 and engages with the second positioning groove 14, thereby fixing the position of the lifting type bearing assembly 3. The supporting plate 31 moves to the upper part of the suitcase 1, but does not separate from the suitcase 1. On the one hand, it is convenient for the placement and fixing of cultural relics. On the other hand, the supporting plate 31 is still within the protection range of the suitcase 1, avoiding the lifting type bearing assembly 3 from separating from the suitcase 1 and then having to carry the cultural relics for a large range of movement, causing unpredictable damage.

[0041] Place the cultural relic steadily on the friction pad 32. The rubber material provides strong friction. Then twist the push ring 35. The push ring 35 engages with the threaded rod 34. Under the push of the push ring 35, the symmetrical extrusion plates 36 clamp the two sides of the cultural relic. The extrusion pad 37 made of sponge material is easy to deform and adaptively fits the surface of the cultural relic while providing strong friction. Under the combined action of the extrusion force of the extrusion plate 36 and the friction force of the extrusion pad 37, the cultural relic is initially fixed. Then lift the handle 332 again to make the positioning block 335 break away from the restriction of the second positioning groove 14, and slowly push the cultural relic carried by the lifting and pulling type carrying assembly 3 to be placed. The cultural relics are placed in the suitcase 1 until the supporting plate 31 moves to the bottom of the suitcase 1, the handle 332 is released, the positioning block 335 pops out again, and engages with the first positioning groove 13 to fix the lifting and pulling bearing assembly 3, and the first air pump 8 is started. The side wall airbags 6 are inflated to fill the other two sides of the cultural relics. The surface of the side wall airbags 6 fits with the surface of the cultural relics and squeezes and fixes the cultural relics, which is suitable for fixing cultural relics of different shapes. Finally, the box lid 4 is closed, the lock buckle 5 is locked, and the second air pump 9 is started. The top airbag 7 is inflated to fill the space above the side wall airbags 6 and the cultural relics to further stabilize the cultural relics. The cultural relics are fixed with flexible contact to prevent them from being bumped and hit during transportation.

[0042] During the transportation of the suitcase 1 with the lid 4 locked, the electrical circuits connected in series by the four groups of first electromagnetic strips 22 and the electrical circuits connected in series by the four groups of metal sheets 233, the resistor strips 214 and the second electromagnetic strips 213 on the four sides of the outer side of the suitcase 1 are opened. The first electromagnetic strips 22 and the second electromagnetic strips 213 are energized to generate magnetism respectively. Since the first electromagnetic strips 22 and the second electromagnetic strips 213 are arranged with the same poles, the electromagnetic repulsive force between the two prevents the collision plate 211 from touching the bottom wall of the protective groove 11. In the initial state, the follower block 232 is at the end of the resistor strip 214 away from the second electromagnetic strip 213, that is, the resistance of the resistor strip 214 connected to the electrical circuit of the metal sheets 233, the resistor strip 214 and the second electromagnetic strip 213 is at the maximum value, the current flowing through the second electromagnetic strip 213 is at the minimum value, and the magnetism generated by the second electromagnetic strip 213 is relatively small. When the outer side of the suitcase 1 encounters an external impact, the collision plate 211 is preferentially impacted. The collision plate 211 approaches the bottom wall of the protective groove 11 after being hit, and the buffer spring 212 is compressed and provides a certain buffer force. Since the length of the connecting rotating rod 231 is fixed, the collision plate 211 will squeeze the connecting rotating rod 231 when approaching the protective groove 11, thereby causing the follower block 232 to slide along the resistor bar 214 toward the second electromagnetic bar 213 under the push of the connecting rotating rod 231, thereby causing the metal sheet 233 to slide on the resistor bar 214. The length of the resistor bar 214 connected to the electrical circuit of the metal sheet 233, the resistor bar 214 and the second electromagnetic bar 213 is reduced, and the resistance value is reduced, thereby increasing the current flowing through the second electromagnetic bar 213, so that the magnetism generated by the second electromagnetic bar 213 is enhanced, thereby increasing the repulsive force between the first electromagnetic bar 22 and the second electromagnetic bar 213, and the external impact force is offset by the magnetic field repulsion force, thereby preventing the suitcase 1 from being impacted and protecting the cultural relics.

[0043] After the cultural relics are transferred to the designated position, it is only necessary to deflate the top airbag 7 through the second air pump 9, then open the lock 5, and deflate the side wall airbag 6 through the first air pump 8. According to the above steps, lift up and remove the lifting and pulling type supporting assembly 3, twist the push ring 35 to loosen the squeezing plate 36 and remove the cultural relics.

[0044] It is worth noting that the application of the first air pump 8 and the second air pump 9 is prior art and will not be described in detail here.

[0045] The above is the overall workflow of the utility model. Just repeat this step next time you use it.
