[0001] The invention relates to the technical field of transporting special-shaped objects, and in particular to a vibration-damping packaging box for special-shaped objects. Background Art

[0002] Special-shaped parts are short for special-shaped objects. Due to the irregular shapes of special-shaped parts, foam is usually filled between the special-shaped parts and the packaging boxes to avoid bumps or collisions during transportation to achieve the function of vibration reduction. However, during road transportation, vehicle scratches or even serious car accidents may occur. The vehicle itself will shake greatly when it is hit, and other vehicles will hit the packaging box, and the foam will also be easily broken. When transporting some medium-sized precision equipment, such as optical microscopes, it is easy to be damaged, causing serious losses. Summary of the invention

[0016] The following will be combined with 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.

[0017] refer to Figure 1 to Figure 7 The present invention protects a vibration-damping packaging box for special-shaped parts, which includes a side wall assembly 12, a top cover 11 is provided at the top of the side wall assembly 12, a bottom plate 13 is provided at the bottom of the side wall assembly 12, and the top cover 11, the side wall assembly 12 and the bottom plate 13 are connected to form a closed space. The number of the side wall assemblies 12 can be a positive integer such as 2, 3, 4 or 5. According to actual needs, the side wall assembly 12 can be a flat plate or a curved plate. If it is a curved plate, the number of the side wall assemblies 12 can be 2.

[0018] The inner wall of the top cover 11 is provided with a top flexible member, which can be a non-inflatable member, such as cotton, sponge or latex layer, etc. It can also be an inflatable member, such as an air bag. The inner wall of the bottom plate 13 is provided with a bottom flexible member, which can be a non-inflatable member or an inflatable member.

[0019] The side wall assembly 12 includes multiple flexible connectors, multiple displacement members and multiple fixing members. The flexible connector can be manually adjusted to extend or shorten. The two ends of the flexible connector are respectively connected to the displacement member and the fixing member. The displacement member can be slightly displaced by pulling it, and can be reset by loosening it.

[0020] The present invention can place the special-shaped part on the bottom flexible part in the bottom plate part 13 by setting the bottom plate part 13, and the bottom flexible part can buffer vibration and protect the special-shaped part during transportation. By setting the side wall assembly 12, the flexible connector in the side wall assembly 12 can be selected to be connected with one of the displacement parts and one of the fixing parts according to the shape of the special-shaped part, and then manually adjusted to extend or shorten it so that the flexible connector part fits on the surface of the special-shaped part. Multiple flexible connectors are staggered to fix the special-shaped part. The flexible connector has two functions. The first function is that the flexible connector itself can undergo a slight deformation, which can reduce the vibration and shaking of the special-shaped part in the horizontal direction during transportation; the second function is that the flexible connector itself can adjust the length, and multiple flexible connectors can be set to different tightness. When the packaging box is hit violently, the tightest flexible connector will break and absorb part of the energy, and then the loose flexible connector plays a fixing role to protect the special-shaped part. To explain in detail, taking four flexible connectors as an example, they can be divided into the first tight flexible connector, the second tight flexible connector, the third tight flexible connector and the fourth tight flexible connector according to different tightness. When the packaging box is hit violently, the order of the four flexible connectors breaking is the first tight flexible connector, the second tight flexible connector, the third tight flexible connector and the fourth tight flexible connector. The flexible connectors breaking in sequence can absorb a large amount of energy and prevent the impact force from damaging the special-shaped parts. By setting the displacement part, the flexible connector can have a smaller extension and contraction to achieve vibration reduction of the special-shaped parts. The flexible connector can pull the displacement part by a small amplitude, and the displacement part can be reset to pull the flexible connector to achieve the vibration reduction function.

[0021] refer to Figure 2~Figure 7 In a specific embodiment, the side wall assembly 12 includes a side plate 121, a rope 123, an elastic member 122 and a fixing ring 125, wherein the flexible connecting member is the rope 123, the displacement member is the elastic member 122, and the fixing member is the fixing ring 125. Among them, the side plates 121 in this embodiment are flat plates, and the number is 4. The rope 123 is a conventional rope, and the length can be adjusted by a buckle, a sliding buckle, etc. The staff can adjust the length of the rope 123 according to the actual shape of the special-shaped part to achieve fixation.

[0022] The elastic member 122 and the fixing ring 125 are respectively arranged on the inner walls of two different side plates 121. There are multiple elastic members 122 and fixing rings 125, such as Figure 5As shown, a plurality of elastic members 122 may be arranged on two adjacent side panels 121, and a fixing ring 125 may be arranged on the remaining two side panels 121; of course, a plurality of elastic members 122 may also be arranged on two opposite side panels 121 (not shown in the figure), and a fixing ring 125 may be arranged on the remaining two side panels 121. Both ends of the rope 123 are connected to the elastic member 122 and the fixing ring 125, respectively.

[0023] By setting the positions of the elastic member 122 and the fixing ring 125, the rope 123 connects the elastic member 122 and the fixing ring 125 to Figure 5 Taking the position of the side plate 121 in the figure as an example, when the elastic member 122 and the fixing ring 125 are arranged on the adjacent side plate 121, for example, Figure 5 There are two sets of elastic members 122 and fixing rings 125 arranged in coordination. The first set of elastic members 122 and fixing rings 125 are respectively arranged on the left side plate 121 and the lower side plate 121; the second set of elastic members 122 and fixing rings 125 are respectively arranged on the upper side plate 121 and the right side plate 121. The ropes 123 in two directions cross to form an X-shaped cross, and a special-shaped piece is arranged at the position where the ropes 123 cross, so as to prevent the special-shaped piece from shaking. Figure 5 For example, when the elastic member 122 and the fixing ring 125 are arranged on opposite side plates 121, the ropes 123 in two directions cross to form a cross, and a special-shaped member is arranged at the intersection of the cross, so as to prevent the special-shaped member from shaking.

[0024] refer to Figure 4 In a specific embodiment, the elastic member 122 includes a frame 1221, and two parallel sliding rods 1222 are provided on the inner side of the frame 1221. The sliding rods 1222 are sleeved with a slider 1223 and a spring 1225, and the spring 1225 can provide a force for the slider 1223 to approach the side plate 121. The frame 1221 is similar to a concave shape, and the sliding rods 1222 are provided on the left and right sides of the frame 1221. The bottom side of the frame 1221 is fitted on the side plate 121. The two sliders 1223 are connected to the connecting rod 1224 by the rope 123 and the connecting rod 1224.

[0025] By setting two sliding rods 1222 and a slider 1223, the sliding of the connecting rod 1224 set on the two sliders 1223 is more stable. Specifically, the rope 123 is connected to the connecting rod 1224. No matter from which angle the rope 123 pulls the connecting rod 1224, the connecting rod 1224 can slide stably along the sliding rod 1222 to achieve vibration reduction.

[0026] refer to Figure 3 Or 5, in a specific embodiment, an inflatable member 124 is further provided on the inner wall of the side plate 121, and the volume of the inflatable member 124 can be expanded or reduced. The inflatable member 124 can be selected as an air bag or an air cushion according to actual needs.

[0027] By arranging the inflatable member 124 on the side plate 121, after the special-shaped piece is placed in the packaging box, the inflatable member 124 is inflated, and the inflatable member 124 has two functions. The first function is that the inflatable member 124 can squeeze the special-shaped piece when it expands, squeezing the special-shaped piece to prevent the special-shaped piece from shaking in the packaging box. The second function is that when the packaging box is hit, the inflatable member 124 can absorb the impact force to prevent the impact force from damaging the special-shaped piece.

[0028] refer to Figure 5 or Figure 6 In a specific embodiment, the inflatable member 124 includes a side airbag 1241 and a flexible column 1242. The side airbag 1241 is arranged on the inner wall of the side plate 121. There are a plurality of flexible columns 1242, and the flexible columns 1242 are arranged on the side of the side airbag 1241 away from the side plate 121. According to different special-shaped members, flexible columns 1242 of different diameters can be selected.

[0029] In this embodiment, multiple flexible columns 1242 are provided, and the flexible columns 1242 are solid columns. The hardness of the flexible columns 1242 is greater than the hardness of the side airbags 1241. Therefore, the flexible columns 1242 have strong support. In addition, when the side of the special-shaped part has irregular grooves or through holes, when the side airbags 1241 expand, the outer end parts of individual flexible columns 1242 can be inserted into the grooves or through holes. Under normal transportation conditions, the flexible columns 1242 inserted into the grooves or through holes can not only prevent the special-shaped parts from shaking, but also play a buffering role. In extreme environments, such as when a wooden packaging box is severely hit, the wooden boards will break, and the broken wooden boards may puncture the side airbags 1241, so that the buffering force of the side airbags 1241 will decrease. In this way, multiple flexible columns 1242 can play the last layer of protection to prevent foreign objects from impacting the special-shaped parts.

[0030] refer to Figure 6 In a specific embodiment, the material of the flexible column 1242 is memory foam, foam or silicone. Among them, the memory foam has the characteristic of slow rebound, which can evenly disperse the pressure and effectively absorb the impact of the packaging box. Foam has the characteristics of light weight, good support and good impact resistance, and can be used as the material of the flexible column 1242. Silicone itself is relatively soft. If silicone is selected as the flexible column 1242, the diameter of the flexible column 1242 needs to be set larger.

[0031] refer to Figure 6 In a specific embodiment, the bottom plate 13 includes a bottom plate 131, and the bottom plate 131 is covered with a flexible pad 133, and the bottom flexible member is the flexible pad 133. The thickness of the flexible pad 133 is relatively thick, and the material of the flexible pad 133 can be memory foam, rubber or latex.

[0032] By providing the flexible pad 133, the vibration of the special-shaped part can be reduced. The purpose of selecting a thicker flexible pad 133 is to wrap the bottom of the special-shaped part as much as possible to achieve sufficient vibration reduction. In addition, when the bottom of the special-shaped part is also irregular, placing it on the flexible pad 133 can prevent the special-shaped part from moving to the greatest extent.

[0033] refer to Figure 6 In a specific embodiment, a plurality of support springs 132 are provided between the flexible pad 133 and the bottom plate 131. The support springs 132 in this embodiment have two functions. The first function is vibration reduction, especially in some bumpy sections, where the packaging box will shake violently, and the support springs 132 can play a vibration reduction role. The second function is support, especially in the horizontal direction, because the support springs 132 will be deformed when the special-shaped part is placed on the flexible pad 133, and the support springs 132 near the bottom edge of the special-shaped part will give the special-shaped part an elastic force obliquely upward. For example, the support springs 132 in front of the bottom of the special-shaped part will squeeze the support springs 132 in front of the bottom of the special-shaped part when the vehicle brakes suddenly, and the support springs 132 in front of the bottom of the special-shaped part will give the bottom of the special-shaped part a backward support force, thereby increasing the stability of the special-shaped part.

[0034] refer to Figure 7 In a specific embodiment, the top cover 11 includes a top plate 111 and a top airbag 112 disposed on the inner wall of the top plate 111. The top airbag 112 can protect the top of the special-shaped part to prevent the top of the packaging box from damaging the special-shaped part; secondly, it can provide partial pressure downwards and cooperate with the support spring 132 to stably place the special-shaped part in the packaging box.

[0035] The above disclosure is only the preferred embodiment of the present invention, which certainly cannot be used to limit the scope of the present invention. Therefore, equivalent changes made according to the claims of the present invention are still within the scope of the present invention.
