Detailed Description

In the following, only certain exemplary embodiments are briefly described. As those skilled in the art will recognize, the described embodiments may be modified in various different ways, all without departing from the spirit or scope of the present application. Accordingly, the drawings and description are to be regarded as illustrative in nature, and not as restrictive.

The present invention will be described in detail with reference to the accompanying drawings. For convenience of description, in the related drawings and the detailed description below, a direction of a side of the opening 201 (or the cover 100) of the case 200 is defined as an upper side, and a direction of a side of the cover 100 pivoted open is defined as a front side.

Fig. 1 shows a schematic view of a compartment according to an embodiment of the application in a closed state. This hutch includes: a case 200 and a cover 100. The box 200 may be a rectangular parallelepiped, a cylinder, or a trapezoid. In this embodiment, the box 200 is a rectangular parallelepiped, and specifically includes: a bottom wall 250 and four side walls, a front wall 230, a rear wall 240, a first side wall 210 and a second side wall 220, respectively. The cabinet 200 forms a storage space therein for storing articles. An opening 201 is provided at one side of the top of the case 200, and the opening 201 communicates the storage space with the outside of the case 200. In this embodiment, the opening 201 may be a rectangular opening 201, and in other embodiments of the present invention, the opening 201 may also have a circular shape, a trapezoid shape, or other possible shapes. The cover 100 is pivotably provided at one side of the case 200 having the opening 201 for opening and closing the case 200.

Fig. 2 shows a schematic view of the bin in an open state according to an embodiment of the present application (in order to show the sealing plate 120 and the resilient member 130, part of the cover body 100 is removed). Fig. 3 shows a schematic view of the compartment in a closed state according to an embodiment of the present application, wherein the cover shell 110 of the cover 100 of fig. 3 is hidden. Fig. 4 shows a side view of the compartment shown in fig. 2 in an open state. As shown in fig. 2 and 3, the cover 100 includes: a cover case 110, a sealing plate 120, and at least one elastic member 130. The cover case 110 is pivotally connected to the case 200. The sealing plate 120 is provided at a side of the cover case 110 facing the opening 201 when the cover body 100 closes the case body 200, for sealing the opening 201 when the cover body 100 closes the case body 200. That is, the sealing plate 120 is disposed between the cover case 110 and the plane where the opening 201 is located when the cover body 100 closes the case body 200. The sealing plate 120 may also be rectangular and may be sized slightly larger than the opening 201 to completely close the opening 201. Each of the elastic members 130 has both ends respectively connected to the facing surfaces of the cover case 110 and the sealing plate 120, and provides a restoring force to the sealing plate 120 when the sealing plate 120 is moved toward the cover case 110 by an external force. The cover body 100 is configured such that, when the cover body 100 closes the case body 200, an end surface of the side of the case body 200 provided with the opening 201 is pressed against a surface of the sealing plate 120 facing the opening 201, so that the elastic member 130 is in a compressed state.

Fig. 5 shows a side sectional view of the compartment according to an embodiment of the present application in a closed state; fig. 6 shows a side sectional view of the compartment according to an embodiment of the application in an open state. As shown in fig. 5, in the present embodiment, when the cover 100 closes the box body 200, the sealing plate 120 completely closes the opening 201, and the elastic member 130 provides a restoring force to the sealing plate 120, so that the sealing plate 120 is tightly pressed against the end surface of the side of the box body 200 where the opening 201 is provided, thereby improving the sealability of the entire compartment. The storage box of the embodiment can be particularly applied to medical refrigeration, and the sealing plate 120 is tightly attached to the opening 201 when the cover body 100 closes the box body 200, so that cold air leakage of the storage box at the opening 201 is effectively reduced, and the overall heat preservation effect of the storage box is improved. In addition, as shown in fig. 6, the end surface may be continuously pressed against the sealing plate 120 during the pivoting opening of the cover body 100, and the sealing plate 120 may escape from the case body 200 by being further moved toward the cover case 110 due to the elastic member 130, thereby solving the interference problem between the sealing plate 120 and the case body 200. The storage box of the embodiment does not affect the pivoting of the cover body 100 in the opening state while tightly sealing the opening 201 in the closing state, thereby solving the technical problem that the sealing and the pivoting cannot be simultaneously realized in the prior art. Furthermore, when the cover 100 closes or opens the box 200, a part of the impact force generated by the cover 100 is absorbed by the elastic member 130, thereby reducing the influence on the box 200 and reducing the damage to the stored goods in the storage box to some extent.

The cover 100 and the body 200 of the bin will be described in detail with reference to fig. 1 to 11, respectively. As shown in fig. 4 to 6, a receiving cavity is formed at a side of the cover case 110 facing the opening 201 for receiving the at least one elastic member 130 and at least partially receiving the sealing plate 120. Specifically, the cover case 110 includes: a top plate 115 and four side plates forming a receiving cavity with the top plate 115. These four side plates are a front plate 113, a rear plate 114, and a first side plate (not shown in the drawings) and a second side plate 112 on the left and right sides, respectively. The elastic member 130 is completely disposed in the receiving cavity, that is, the elastic member 130 may be completely hidden by the cover case 110 and the sealing plate 120. The sealing plate 120 may be disposed parallel to the top plate 115, and the sealing plate 120 has a thickness and at least a portion in a thickness direction thereof beyond the receiving cavity to be pressed by the end surface when the cover body 100 closes the case body 200. That is, the sealing plate 120 is partially disposed in the receiving cavity when it is not applied with an external force, and the remaining portion is exposed out of the cover case 110. This requires that the elastic member 130 keeps at least a portion of the sealing plate 120 exposed from the cover case 110 in a free state. It will be appreciated that the size of the sealing plate 120 should be slightly smaller than the size of the mouth of the receiving cavity so as to be received within the receiving cavity. The elastic member 130 includes a spring pad, and a plurality of spring pads may be uniformly arranged on a side of the sealing plate 120 facing the top plate 115 and connected to the top plate 115 such that various portions of the sealing plate 120 can be subjected to restoring forces of the spring pads. In the present embodiment, as shown in fig. 3, the number of spring pads is 5, which are respectively disposed at positions adjacent to four corners of the sealing plate 120 and at the center of the sealing plate 120. Of course, in other embodiments of the present invention, the elastic member 130 may be other types of elastic members, such as elastic springs, and the number of the elastic members 130 may be more than 5 or less than 5, and may be arranged in other manners. In summary, the implementation of the present invention is not limited by the specific form, the specific number and arrangement of the elastic members 130. In addition, it is understood that both ends of the spring pad may be directly connected to the surface of the top plate 115 or the sealing plate 120, or may be indirectly connected to the top plate 115 or the sealing plate 120 through an auxiliary support structure on the top plate 115 or the sealing plate 120.

The first and second sidewalls 210 and 220 located at the left and right sides of the case 200 are used to mount the cover 100. Wherein the first sidewall 210 includes a first extension 211 extending beyond the end surface, and the second sidewall 220 includes a second extension 221 extending beyond the end surface. The cover shell 110 is pivotally mounted to the inside of the two extensions. Fig. 7 illustrates a schematic view of the compartment with the cover 100 removed according to an embodiment of the present application, and as shown in fig. 7, the first side wall 210 and the second side wall 220 are both higher than the front wall 230 and the rear wall 240, and the excess portions thereof are defined as the first extension 211 and the second extension 221. The first extension portion 211 and the second extension portion 221 have the same height and shape, and are symmetrically disposed.

The first extension 211 and the second extension 221 are provided at inner opposite positions thereof with rotation shaft assemblies, respectively, each rotatably coupled to the cover case 110. Specifically, as shown in fig. 3 and 4, a first rotating shaft assembly 310 is provided on the first extension portion 211, the first rotating shaft assembly 310 is provided at a corner of the first extension portion 211 near the upper edge of the rear wall 240 and the first extension portion 211, a second rotating shaft assembly 320 is provided on the second extension portion 221, and the second rotating shaft assembly 320 is provided at a corner near the upper edge of the rear wall 240 and the second extension portion 221. The first rotating shaft assembly 310 and the second rotating shaft assembly 320 are opposite to each other, and the connection line therebetween is a pivot axis of the cover 100, about which the cover 100 pivots. The vertical distance from the pivot axis to the end surface where the opening 201 is located may be set to be greater than the first preset distance to provide a sufficiently large pivot space for the rotation shaft assembly, and may also be set to be less than the second preset distance so that the sealing plate 120 is in contact with the end surface where the opening 201 is located when the cover body 100 closes the case 200. The second preset distance is greater than the first preset distance, and both the first preset distance and the second preset distance can be flexibly set according to the specific sizes of the box body 200 and the cover body 100. In order to ensure the complete and aesthetic appearance of the storage box, the first and second side panels 112 and 112 of the cover case 110 should be shaped to match the shapes of the first and second extensions 211 and 221, such that when the cover body 100 closes the box body 200, the top panel 115 of the cover case 110 is flush with the upper edges of the two extensions, the front panel 113 is flush with the front edges of the two extensions and the rear panel 114 is flush with the rear edges of the two extensions.

At least one pivot subassembly in two above-mentioned pivot subassemblies is the damping pivot, and in this embodiment, first pivot subassembly 310 is the damping pivot the utility model discloses in some other embodiments, second pivot subassembly 320 can be the damping pivot for non-damping pivot or two pivot subassemblies. FIG. 8 illustrates a schematic view of the first spindle assembly 310 of the bin according to an embodiment of the present application; FIG. 9 illustrates the first shaft assembly 310 of FIG. 8 with the first connector 313 removed. As shown in fig. 8, the damping rotating shaft includes: a rotating shaft part 311, a damping washer 312 and a first connecting piece 313. The rotation shaft portion 311 is rotatably mounted to the first extension portion 211 about its axis. Specifically, the first extension portion 211 is provided with a through hole, the rotation shaft portion 311 crosses the through hole, and two ends of the rotation shaft portion are respectively located at two sides of the first extension portion 211. The end of the rotating shaft 311 extending to the cover 100 can also enter the cover 100 through a through hole preset on the first side plate. A damping washer 312 is integrally formed on the rotation shaft portion 311, and one side surface of the damping washer 312 is in contact with a surface of the extension portion to provide rotation resistance. Specifically, when the damping rotation shaft is mounted on the first extension portion 211, the damping washer 312 is located on a side of the first extension portion 211 facing away from the cover body 100 and is in close contact with the side surface. When the cover body 100 pivots, the damping washer 312 generates a resistance force by friction with the surface of the first extension portion 211 to hinder the rotation of the cover body 100. A first connector 313 is provided at an end of the rotation shaft portion 311 protruding toward the cover case 110 for fixedly connecting the rotation shaft portion 311 to the cover case 110. As shown in fig. 9, one end of the rotation shaft portion 311 connected to the first connection member 313 is rectangular in cross section, and accordingly, a rectangular hole for receiving the end of the first connection member 313 is formed in the first connection member 313, so that the rotation shaft portion 311 can rotate with the rotation of the first connection member 313. In this embodiment, the first connector 313 may be connected to the top plate 115 of the cover shell 110 by screws, and in other embodiments of the present invention, the first connector 313 may also be connected to the top plate 115, the first side plate or the rear plate 114 of the cover shell 110 by other methods such as clamping, adhering, and the like. When the cover body 100 pivots, the first connecting member 313 rotates along with the cover shell 110, and further drives the rotating shaft portion 311 to rotate, and the damping gasket 312 and the first extending portion 211 generate frictional resistance.

The storage box of the embodiment increases the external force required by the pivoting of the cover body 100 by arranging the damping rotating shaft, thereby reducing the opening and closing speed of the cover body 100, effectively reducing the impact of the cover body 100 on the box body 200, and reducing the risk that the stored articles in the box are damaged due to the impact. In addition, since the damping rotation shaft is provided, a bidirectional damping torque of about 20kgf · cm can be applied to the cover body 100, and thus the cover body 100 can be maintained at an open angle after being opened, thereby preventing the cover body 100 from being automatically closed by gravity or being pivoted by being disturbed by other external forces.

In the present embodiment, the second rotating shaft assembly 320 is a non-damping rotating shaft, and fig. 10 shows a schematic view of the second rotating shaft assembly 320 of the bin according to an embodiment of the present application; fig. 11 shows a schematic view of the second shaft assembly 320 of fig. 10 with the second coupling member 323 removed. As shown in fig. 10, the second rotating shaft assembly 320 specifically includes: a support 321, a fixed shaft 322, and a second link 323. The supporting portion 321 is disposed on a side of the second extending portion 221 facing away from the cover body 100, and is used for supporting the fixing shaft 322. The fixed shaft 322 is disposed at the top end of the support portion 321. The second extending portion 221 is provided with a through hole, the fixing shaft 322 traverses the through hole, two ends of the fixing shaft 322 are respectively located at two sides of the second extending portion 221, and one end of the fixing shaft 322 extending towards the cover body 100 can enter the cover body 100 through the through hole preset on the second side plate 112. The second coupling member 323 is provided at an end of the fixing shaft 322 protruding toward the cover case 110, and as shown in fig. 11, the end of the fixing shaft 322 has a circular cross-section. The second coupling member 323 has a similar structure to the first coupling member 313 and is fixedly coupled to the top plate 115 of the cover body 100 as the first coupling member 313, except that the hole of the second coupling member 323 for receiving the fixing shaft 322 is a circular hole. That is, the second coupling member 323 and the fixed shaft 322 are relatively rotatable. In contrast, the first connecting member 313 and the rotating shaft 311 are held stationary and cannot rotate relative to each other. Therefore, there is no relative movement between the fixing shaft 322 and the second extension 221, so that there is no damping to hinder the rotation of the cover body 100.

In order to provide a sufficient space for the rotary shaft assembly, as shown in fig. 4 and 5, the rotary shaft assembly is disposed between the sealing plate 120 and the top plate 115. In other words, the portions of the first and second rotating shaft assemblies 310 and 320 protruding into the interior of the cover body 100 are disposed in the receiving cavities of the cover case 110, thereby providing a sufficient installation space for the first and second coupling members 313 and 323 without interference from other components during their rotation.

The case 200 further includes: outer shell 260 and inner bladder 270. The inner container 270 has a storage space formed therein, and the mouth of the inner container 270 is the opening 201 of the case 200. An insulating layer 290 is formed between the outer shell 260 and the inner container 270. As shown in fig. 5 and 6, in the present embodiment, the cabinet 200 has a double structure, and each wall (the front wall 230, the rear wall 240, the bottom wall 250, and the left and right side walls) of the cabinet 200 has a double structure of the outer case 260 and the inner case 270, and the heat insulating layer 290 is provided between the double structures. The insulation layer 290 may be a vacuum layer or may be filled with an insulation material to improve the insulation effect of the insulation layer 290. As mentioned above, the storage compartment of the present embodiment may be particularly applicable to medical refrigeration. For example, the storage box can be used for medical articles such as vaccines, human blood and medicines in refrigerated transportation. Therefore, the requirement of the storage box on the heat preservation performance of the box body 200 is very strict, and in the embodiment, the heat insulation layer 290 is arranged on the box body 200, so that the heat insulation effect of the box body 200 is improved, and the cold leakage of the refrigeration box is effectively prevented.

As shown in fig. 5 and 6, the case 200 further includes: an end plate 280. The end plate 280 is provided at one side of the case 200 having the opening 201 for enclosing the thermal insulation layer 290, and the upper surface thereof forms an end surface. The end plate 280 is disposed on the plane of the opening 201 and serves to connect the outer shell 260 and the inner container 270 of the container 200. In this embodiment, since the cross-sections of the outer shell 260 and the inner container 270 are both rectangular, the end plate 280 may be a rectangular frame, and the width of the frame is the thickness of the thermal insulation layer 290. Preferably, the end plate 280 may be integrally formed with the inner container 270. It should be understood that in other embodiments of the present invention, the box 200 may have only one layer of structure and thus no end plate 280, and the end surface may be understood as the thickness section of the wall of the box 200 at the opening 201.

The above-mentioned hutch still includes: a gasket 500. The gasket 500 is disposed on the end plate 280. As shown in fig. 2 and 7, in this embodiment, the gasket 500 may also be a rectangular frame having a shape matching the end plate 280. The above-mentioned gasket 500 is preferably made of a flexible material such as rubber, sponge, etc., and has a thickness of 1mm to 3mm, and preferably 2 mm. When the cover 100 is closed, the sealing plate 120 is actually in direct contact with the gasket 500, and the flexible gasket 500 can better seal the gap between the box body 200 and the sealing plate 120 when pressed against the sealing plate 120, thereby further improving the sealing effect of the storage box.

In the present embodiment, the sealing plate 120 is preferably a vacuum insulation plate. The vacuum Insulation panel is also called VIP (vacuum Insulation Panel), is one of Insulation materials, is formed by compounding superfine inorganic fibers and a vacuum protection surface layer, and can effectively avoid heat transfer caused by air convection, so that the heat conductivity coefficient can be greatly reduced to be below 0.0025W/m.K.

The open side of the cover 110 is further provided with a latch 410, and a latch 420 is further provided at a corresponding position on the surface of the case 200, and the latch 410 is engaged with the latch 420 to lock the storage compartment. Specifically, as shown in fig. 5 and 6, an extension is provided on the front plate 113 of the cover case 110 to extend downward to a front position of the front wall 230 of the case 200.
