Description

Technical Field

[0001] The present invention relates to the field of containers, and in particular to a reinforcement structure, a cover plate and a coaming box. Background Art

[0002] As a container for storing or transshipping goods, turnover containers are becoming more and more widely used in the current era of increasingly developed logistics.

[0003] Most of the turnover containers on the market today are traditional designs from more than a decade ago, with little change in internal dimensions, craftsmanship, appearance, weight, and strength. The existing technology for double-layer blister cardboard boxes has not been able to solve the problems of heavy box weight and low load-bearing capacity (including pressure), and the top and bottom covers are relatively soft, and will sag due to gravity during use. In addition, the compressive strength is relatively poor, so "cross-shaped" steel pipes are often used as reinforcements to improve the load-bearing capacity of the top and bottom covers of double-layer blister cardboard boxes, and they are also light in weight. Welding technology is often used to weld the steel pipes at the joints of the "cross-shaped" steel pipes. Due to the characteristics of plastic and its processing technology, during use, the steel pipes will be subjected to force toward the center of the top and bottom covers along with the plastic. The steel pipes are easily deformed into an arc shape by the force until they break, which shortens the service life of the top and bottom covers of double-layer blister cardboard boxes.

[0004] Therefore, there is an urgent need for a reinforcement structure that can solve the problem that the reinforcement members used in the top and bottom covers of double-layer blister board boxes in the prior art are easy to break and have a short lifespan. Summary of the Invention

[0012] In one embodiment, the thickness of the elastic portion ranges from 1 mm to 3 mm.

[0013] In one embodiment, the first connecting portion is clamped onto the outer periphery of the support member adjacent thereto, and the second connecting member is at least partially inserted into one end of the support member adjacent thereto.

[0014] In one embodiment, the first connecting portion has wrinkles, and the wrinkles abut against the supporting member of the first connecting portion sleeve.

[0015] In one embodiment, one end of the second connecting portion inserted into the support member is a sawtooth structure, and the tooth tops of the sawtooth structure abut against the inner periphery of the support member.

[0017] The present invention further provides a cover plate, comprising:

[0018] a first cover;

[0019] a second cover body, the second cover body being connected to and covering the first cover body; and

[0020] According to any of the above reinforcement structures, the reinforcement structure is clamped between the first cover body and the second cover body.

[0021] In one embodiment, the first cover body and the second cover body are sealed and connected to form a cavity, and the reinforcement structure is disposed in the cavity.

[0022] In one embodiment, the first cover has a first main body and a first flange, and the first flange surrounds the outer circumference of the first main body;

[0023] The second cover has a second main body and a second flange, the second flange surrounds the outer periphery of the second main body, and the first flange surrounds the outer periphery of the second flange;

[0048] Hereinafter, embodiments of the present invention will be described with reference to the accompanying drawings.

[0049] like Figure 1 as well as Figure 2 As shown, an embodiment of the present invention provides a reinforcement structure 100, which includes: two parallel support members 10, two parallel support members 12, and a connecting member 20. The two parallel support members 10 and the two parallel support members 12 are arranged in accordance with Figure 1 The interconnected parts 10 and 12 are connected to form a closed loop area 11. The connecting member 20 connects the adjacent supporting members 10 and 12, and the connecting member 20 has an elastic portion 21 for providing elastic force toward the closed loop area 11.

[0050] In the prior art, welding technology is typically used to weld the support members 10. During use, the support members 10 are typically subjected to forces directed toward the closed-loop area 11. Over time, the support members 10 will deform in an arc shape under the action of the forces until they break. Compared to the prior art, the embodiments of the present invention use connectors 20 to connect adjacent support members 10. The elastic portion 21 of the connector 20 can provide elastic forces directed toward the closed-loop area 11, and the support members 10 connected to the connector 20 can displace as the elastic portion 21 deforms, allowing the support members 10 to undergo relative displacement without breaking. Therefore, the reinforcement structure 100 provided by the embodiments of the present invention is not easily broken and has a long service life.

[0051] It should be understood that, although the present invention is not limited to four support members 10, the reinforcement structure 100 may also include three support members 10 or more than four support members 10 without departing from the scope of the present invention, and those skilled in the art may make such arrangements based on actual needs. In this embodiment, adjacent support members 10 and support members 12 are connected by connectors 20. In other embodiments, one end of a support member 10 may be connected to one support member 12 via a connector, and the other end of the support member 10 may be directly welded to another support member 12.

[0052] In addition, if Figure 1 as well as Figure 2 As shown, the connector 20 has a first connector portion 22 and a second connector portion 23, and the first connector portion 22 and the second connector portion 23 are respectively used to connect the adjacent support member 10 and the support member 12. The elastic portion 21 connects the first connector portion 22 and the second connector portion 23. Those skilled in the art can configure it according to actual needs.

[0053] Preferably, if Figure 1 as well as Figure 2 As shown, the elastic portion 21 is a plate, and is perpendicular to the plane of the axes of the adjacent support members 10 and 12. With this arrangement, when a force is applied to the support member 12, the elastic portion 21 connected to the support member 10 will deform more significantly. This allows the elastic portion 21 to bear more of the force for the support member 12, allowing the support member 12 to withstand greater relative displacement without breaking, thereby extending the service life of the reinforced structure 100. Furthermore, the elastic portion 21 may also be configured as a spring or other elastically deformable structure, without departing from the scope of the present invention. Persons skilled in the art can design the arrangement based on practical needs.

[0054] Furthermore, the thickness of the elastic portion 21 ranges from 1 mm to 3 mm. The thickness of the elastic portion 21 is the thickness of the plate body of the elastic portion 21, that is, the thickness of the elastic portion 21 along the bending direction when bent. Those skilled in the art can set it according to actual needs.

[0055] Preferably, if Figure 1 as well as Figure 2 As shown, the first connecting portion 22 is clamped onto the outer periphery of the adjacent support member 10, and the second connecting portion 23 is partially inserted into one end of the adjacent support member 12. The prior art requires welding adjacent support members 10 and 12, but the present invention simply connects the support members 10 and 12 through clamping and plugging. This arrangement simplifies the processing of the reinforcement structure 100, and those skilled in the art can configure it according to actual needs.

[0056] Furthermore, if Figure 1 as well as Figure 2 As shown, the first connecting portion 22 has folds 221, which abut against the support member 10 on which the first connecting portion 22 is clamped. The folds 221 provide greater friction between the first connecting portion 22 and the clamped support member 10, making it easier for the first connecting portion 22 to be clamped on the support member 10. Those skilled in the art can configure the folds according to actual needs.

[0057] In addition, if Figure 1 as well as Figure 2 As shown, one end of the second connecting portion 23 inserted into the support member 12 is a sawtooth structure 231, and the tooth tops of the sawtooth structure 231 abut against the inner periphery of the support member 12. This arrangement of the second connecting portion 23 can make it easier to insert the support member 12, and those skilled in the art can make the arrangement according to actual needs.

[0058] In addition, if Figure 1 as well as Figure 2As shown, the reinforcement structure 100 includes: two parallel support members 10 and two parallel support members 12, with adjacent support members 10 and support members 12 being perpendicular to each other. The two ends of a pair of parallel support members 10 are connected to the other pair of parallel support members 12 via connectors 20, the second connector 23 is at least partially inserted into the end sides of the pair of parallel support members 12, and the first connector 22 is clamped around the outer periphery of the other pair of parallel support members 10. In the field of double-layer blister packaging, the clamped pair of parallel support members 10 are held between the side blocks of the cover plate, and the closed loop area 11 formed by the two parallel support members 10 and the two parallel support members 12 surround each other, covering the center position of the cover plate. Since the support members 10 and 12 are fixed in four directions, twisting and deformation during use can be prevented. Furthermore, during use, the cover plate contracts toward the center, and the support members 12 are subjected to forces directed toward the closed-loop area 11. Connectors 20 are used to connect adjacent support members 12. The elastic portion 21 of the connector 20 provides elastic force directed toward the closed-loop area 11, and the support members 12 connected to the connector 20 can move as the elastic portion 21 deforms, allowing the support members 10 and 12 to move relative to each other without breaking. Therefore, the reinforcement structure 100 provided by the embodiments of the present invention is not susceptible to breakage and has a long service life. The connector 20, due to its inherent elasticity and structure, can partially offset the contraction offset, preventing the support members 10 from breaking through the cover plate.

[0059] like Figure 3 、 Figure 4 as well as Figure 7 As shown, another embodiment of the present invention further provides a cover plate, comprising: a first cover body 40, a second cover body 50, and a reinforcement structure 100. The second cover body 50 is connected to and covers the first cover body 40. The reinforcement structure 100 is sandwiched between the first cover body 40 and the second cover body 50. The reinforcement structure 100 is the same as the reinforcement structure 100 described above and will not be described in detail here.

[0060] In the prior art, welding technology is typically used to weld the support members 10. During use, the support members 10 are typically subjected to forces directed toward the closed-loop area 11. Over time, the support members 10 will deform in an arc shape under the action of the forces until they break. Compared to the prior art, the embodiments of the present invention use connectors 20 to connect adjacent support members 10. The elastic portion 21 of the connector 20 can provide elastic forces directed toward the closed-loop area 11, and the support members 10 connected to the connector 20 can be displaced as the elastic portion 21 deforms, allowing each support member 10 to undergo relative displacement without breaking. Therefore, the reinforcement structure 100 provided by the embodiments of the present invention is not easily broken and has a long service life. Consequently, the cover plate using the reinforcement structure 100 also has a longer service life.

[0061] Preferably, if Figure 4 As shown, the first cover 40 and the second cover 50 are sealed together to form a cavity 30, and the reinforcement structure 100 is disposed within the cavity 30. The provision of the cavity 30 can reduce the weight of the cover, and the cover can achieve both light weight and high pressure resistance. Those skilled in the art can adjust the configuration according to actual needs.

[0062] Furthermore, if Figure 8 as well as Figure 9 As shown, the first cover body 40 has a first main body 41 and a first flange 42, and the first flange 42 surrounds the outer periphery of the first main body 41. The second cover body 50 has a second main body 51 and a second flange 52, and the second flange 52 surrounds the outer periphery of the second main body 51, and the first flange 42 surrounds the outer periphery of the second flange 52. A groove 53 is provided around the outer periphery of the second main body 51, and the second flange 52 surrounds the outer periphery of the groove 53. The groove 53 can be operably inserted into the plate body to form a receiving space with an opening. With this arrangement, the side panels can be easily and quickly inserted into the cover plate to form the box body, which improves efficiency. Those skilled in the art can make arrangements according to actual needs.

[0063] like Figure 5 as well as Figure 7 As shown, another embodiment of the present invention further provides a panel box, comprising: a roof 60, a floor 70, and a plurality of side panels. The side panels are connected to the floor and surround the floor to form a storage space with an opening. The roof is used to open or cover the opening of the storage space. The structure of the cover in the above embodiment is applied to the roof 60 and the floor 70. However, the roof 60 and the floor 70 are used in different areas of the panel box. The floor 70 is used as a base at the bottom of the panel box, and the roof 60 is used as a top cover at the top of the panel box. The structures of the roof 60 and the floor 70 are as follows: Figure 3 and Figure 7 As shown, the structures of the sky cover 60 and the ground cover 70 are partially different to meet the actual use. It is understandable that in some embodiments, the structures of the sky cover 60 and the ground cover 70 can also be the same.

[0064] Specifically, the canopy 60 is as follows Figure 5 The cover plate has a first cover body 40, a second cover body 50 and a reinforcement structure 100. The second cover body 50 is connected to the first cover body 40. The reinforcement structure 100 is sandwiched between the first cover body 40 and the second cover body 50. The reinforcement structure 100 is the reinforcement structure 100 described above. The first cover body 40 and the second cover body 50 are sealed and connected to form a cavity 30 (such as Figure 4As shown in the figure, the first cover 40 has a first main body 41 and a first flange 42, with the first flange 42 surrounding the outer circumference of the first main body 41. The second cover 50 has a second main body 51 and a second flange 52, with the second flange 52 surrounding the outer circumference of the second main body 51, and the first flange 42 surrounding the outer circumference of the second flange 52. A groove (not shown) is defined around the outer circumference of the second main body 51, and the second flange 52 surrounds the outer circumference of the groove.

[0065] The ground cover 70 has the same structure as the sky cover 60, but the ground cover 70 serves as the bottom of the panel box and has different parts from the sky cover 60. Figure 7 The cover plate has a first cover body 40, a second cover body 50 and a reinforcement structure 100. The second cover body 50 is connected to the first cover body 40 and covers the first cover body 40. The reinforcement structure 100 is sandwiched between the first cover body 40 and the second cover body 50. The reinforcement structure 100 is the reinforcement structure 100 described above. The first cover body 40 and the second cover body 50 are sealed and connected to form a cavity 30 (not shown in the figure). The first cover body 40 has a first main body 41 and a first flange 42, and the first flange 42 surrounds the outer periphery of the first main body 41. The second cover body 50 has a second main body 51 and a second flange 52, and the second flange 52 surrounds the outer periphery of the second main body 51. The first flange 42 surrounds the outer periphery of the second flange 52. A groove 53 is provided around the outer periphery of the second main body 51, and the second flange 52 surrounds the outer periphery of the groove 53. The side panel can be operably inserted into the groove 53 to form a receiving space with an opening, and when the canopy 60 covers the opening of the receiving space, the top of the side panel is inserted into the canopy 60. In addition, the ground cover 70 is provided with a plurality of protruding support legs 71 facing away from the sky cover 60 .

[0066] In the prior art, welding technology is usually used to weld adjacent support members 10 and support members 12. During use, the support member 12 is usually subjected to a force toward the closed loop area 11. Over time, the support member 12 will deform in an arc shape under the action of the force until it breaks. Compared with the prior art, the embodiment of the present invention uses a connector 20 to connect the adjacent support members 10 and support members 12. The elastic portion 21 of the connector 20 can provide an elastic force toward the closed loop area 11, and the support member 12 connected to the connector 20 can be displaced as the elastic portion 21 deforms, so that the support members 10 and 12 can produce relative displacement without breaking. Therefore, the reinforcement structure 100 provided by the embodiment of the present invention is not easy to break and has a long service life. As a result, the cover plate using the reinforcement structure 100 also has a longer service life. The sky cover 60 and the ground cover 70 in this embodiment have a longer service life.
