detailed description

Referring to Figures 1-4, the cultural relics box of the present invention includes an outer box 1 and an inner box 2, and a bracket 3 connected between the outer box 1 and the inner box 2. The inner box 2 is used to place cultural relics, and it can be relatively Outer box 1 swings left and right and pitches forward and backward and mixes motion.

Wherein the bracket 3 is rotatably connected to the outer box 1 through the bracket buffer device 9 . As shown in Figures 5-7, the bracket buffer device 9 includes a base 91 and two opposite arm-shaped pieces 92 arranged on the base 91, and the two opposite arm-shaped pieces 92 are provided with at least There is a pair of protrusions 93 with a gap between the pair of protrusions 93 . The upper and lower sides of the protrusions are arc-shaped, and the upper and lower sides of a pair of protrusions 93 form a large arc that can accommodate the rod of the bracket 3, and when the protrusions 93 are two or more pairs, A substantially circular arc is formed between adjacent pairs of protrusions 93 .

The buffer device 9 is made of elastic material as a whole, such as elastic rubber, elastic resin, etc., and the elasticity of the buffer device can be adjusted by selecting materials, sizes, etc. as required. In a preferred solution, referring to FIG. 10 , grooves 94 are formed on the arm member 92 , which can be used to place elastic components such as springs, so that the elasticity of the arm member 92 of the buffer device 9 can be adjusted by selecting the stiffness of the spring.

Wherein, the support 3 includes a ring-shaped support body and a first shaft 31 perpendicular to the support body in the first horizontal direction, and a second shaft 32 perpendicular to the support body in the second horizontal direction, wherein the first shaft 31 and the first shaft 31 are perpendicular to the support body in the second horizontal direction. The two axes 32 are vertical, and relative to the bracket body, one extends inward and the other extends outward. Wherein, the first shaft 31 can be inserted into the groove or hole surrounded by the protrusion 93 of the bracket buffer device 9 provided on the outer box 1 , so that the bracket 3 can rotate around the first horizontal direction relative to the outer box 1 . The inner box 2 is provided with a second hole, and the second shaft 32 can be inserted into the second hole so that the inner box 2 can rotate around a second horizontal direction relative to the bracket 3 . In this way, the inner box 2 can rotate around the outer box 1 around the first and second horizontal directions and their compound directions.

Wherein, the inner box 2 has a buffer material 4 inside, such as elastic or flexible materials such as foamed resin, rubber, and foamed plastics. As shown in the figure, the bottom of the inner box 2 has a counterweight layer or a counterweight, so that the bottom surface of the inner box 2 is the heaviest and balanced, and the center of gravity is below the middle position of the two second axes 32, so that it can be used when empty and place cultural relics. All the time, the bottom surface can be kept horizontal and downward. Moreover, when the cultural relic itself has uneven weight, a counterweight made of other elastic materials can be placed in the inner box 2, so that the inner box 2 as a whole keeps the bottom face down.

When working, the first shaft 31 of the bracket 3 is mounted on the upper surface of the pair of protrusions 93 of the buffer device 9 and can rotate.

The first shaft 31 and the second shaft 32 can also be arranged on the outer box 1 and the inner box 2 , and corresponding connection holes are arranged on the bracket 3 . In addition, the first shaft 31 and the second shaft 32 and the bracket body bracket may have a retractable mechanism (such as a threaded connection structure), which facilitates the installation and disassembly of the bracket 3 and the outer box 1 and the inner box 2 .

The outer box 1 described in the figure is a box-shaped structure, but it should be known that a non-enclosed frame can also be used, as long as the support can be realized. Preferably, the buffer device 9 is embedded in the inner wall of the outer box 1 and keeps the surface of the buffer device flush with the inner wall of the outer box 1 .

Below in conjunction with accompanying drawing illustrate the work process of cultural relics case of the present invention:

When the cultural relics box falls or falls, the outer box 1 will tilt. For example, it deflects around the first horizontal direction. At this time, the bracket 3 rotates around the first axis 31, and the inner box 2 remains still under the action of the counterweight. Similarly, when the outer box deflects around the second horizontal direction, or when compound deflection occurs, the inner box 2 rotates around the second axis 32 to keep the bottom surface of the inner box 2 horizontally downward.

When the cultural relics box collides with the bottom surface, the buffering of the cultural relics can be realized through the two-stage damping structure of the support buffer device 9 and the buffer material 4 .

Since the inner box 2 keeps the bottom surface horizontally downward, the position and posture of the cultural relics do not change during this process, and the shock-absorbing position with the buffer material 4 is still the position with the largest shock resistance, which will not cause damage to the cultural relics.

When the landing collision force is greater than a certain value, the force applied by the bracket 3 to the bracket buffer device 9 causes the arm 92 to deform in the left and right directions, and when the gap between the pair of protrusions 93 after deformation is greater than the rod diameter of the bracket 3, The bracket 3 falls through the gap onto the upper surface of the next pair of protrusions 93 . During this process, the impact force of the bracket 3 is fully released. If the impact force is still very large at this time, the bracket 3 continues to deform the arm 92 and dampen the vibration, or pass through the gap between the second pair of protrusions 93 and fall onto the next pair of protrusions. Through two or more consecutive deformation releases, the impact force of the support is reduced, thereby reducing the impact received by the cultural relics. This cushioning structure of the present invention makes the support 3 go down so that the gap between the protrusions 93 needs a larger force (because the moment arm becomes shorter, the same amount of deformation requires more force), thus ensuring In the initial impact, the cushioning force of the buffer device 9 to the support is less, so as not to become a hard impact.

And the first shaft 31 of the support 3 can rotate on each pair of protrusions 93, so that when it swings after hitting the ground, it can still ensure that the inner box remains horizontal.

In the preferred solution, when the cultural relic is in a stable position (for example, the bottom of the warehouse, etc.) and will not fall, it is not necessary for the cultural relic to maintain a state of free rotation between the inner box 2 and the outer box 1 . At this time, as shown in Figure 4, the first hole 5 is a long hole extending in the vertical direction, which can facilitate the lifting of the bracket 3, and there is a first horizontal hole connected to a certain position in the middle of the first hole 5. groove 7, and a second horizontal groove 6 is provided on the side wall of the outer box 1 opposite to the second shaft 2.

The first shaft 31 lifts up along the first hole 5 and reaches the first horizontal slot 7 , and can move along the first horizontal slot 7 , so that the bracket body can be inserted into the second horizontal slot 6 . In this way, the support 3 is fixed to the outer case 1 and cannot be rotated any more. Preferably, an anti-falling structure, such as a small boss (see FIG. 10 ), is provided in the second horizontal groove 6 .

As shown in Figures 9 and 10, preferably, the first hole 5 and the first horizontal groove 7 are groove structures with a small mouth and a large inside with a convex section. The specific implementation method can be that the two ends of the top of the groove are formed by the baffle plate 8, and of course other methods can also be used. Correspondingly, the end portion of the first shaft 31 is a spherical structure with a diameter larger than the diameter of the rod, and the spherical structure can be accommodated in the inner part of the groove, but cannot pass through the gap of the baffle plate 8 (that is, the gap of the groove). Mouth), so that the support 3 is not easy to fall off from the first hole 5 or the horizontal groove 7 during work, especially when the cabinet deflects and collides with the ground, which ensures the normal operation of the cultural relics box.

Of course, the second horizontal groove 6 may also adopt a groove structure with a convex cross-section.

The above is only a preferred embodiment of the present invention, and it should be pointed out that for those of ordinary skill in the art, some improvements and modifications can be made without departing from the principle of the present invention. It should be regarded as the protection scope of the present invention. In addition, although some specific terms are used in this specification, these terms are only for convenience of description and do not constitute any limitation to the present invention.
