[0038] The following will be combined with the embodiments and drawings to clearly and completely describe the concept, specific structure and technical effects of the present invention so as to fully understand the purpose, scheme and effect of the present invention. It should be noted that the embodiments and features in the embodiments of this application can be combined with each other unless there is a conflict. The same reference numerals used throughout the drawings indicate the same or similar parts.

[0039] It should be noted that, unless otherwise specified, when a feature is referred to as being "fixed" or "connected" to another feature, it may be directly fixed or connected to the other feature or indirectly fixed or connected to the other feature. Furthermore, terms such as "upper," "lower," "left," and "right" used in this disclosure are intended solely to describe the relative positions of the components of the disclosure as shown in the accompanying drawings.

[0040] Reference Figures 1 to 7, a storage device with an automatically opening and adjustable opening, comprising a side wall and a tray 1. The side wall is connected to the tray 1 to form a receiving groove with an upward opening. The tray 1 forms the bottom of the receiving groove. A flexible storage bag can be sleeved in the receiving groove. The side wall is a through groove structure with a hollow structure. Both ends of the through groove have a first opening and a second opening respectively. The adjustable range of the size of the first opening is relatively large, and the tray 1 can pass through within a certain adjustable range of the opening. The first opening forms the opening 5 of the receiving groove. The opening of the receiving groove is the opening of the storage device with an automatically opening and adjustable opening in this solution. The tray 1 is located at the second opening and blocks this second opening. And the structural dimensions of the tray 1 are slightly smaller than the structural dimensions of this second opening, so that the tray 1 can pass through the second opening, facilitating the removal of the tray 1 from the opening 5 of the receiving groove, thereby facilitating the cleaning of the tray 1. One side of the tray 1 facing the opening 5 of the receiving groove forms the bottom of the receiving groove. When an item does not fall into the flexible storage bag but into the receiving groove, the setting of the tray 1 can prevent the item falling into the receiving groove from directly falling to the bottom surface.

[0041] The side wall includes a first frame 2 and a second frame 3 that are structurally matched and docked. The cross-sections of the first frame 2 and the second frame 3 are both approximately U-shaped. After the two frames are matched and docked, the cross-section is approximately square-shaped. The first frame 2 and the second frame 3 are hinged at one end close to the tray 1. The two hinge joints are the first hinge joint 4 and the second hinge joint 7 respectively. The positions of the two hinge joints correspond to each other, and the two hinge joints can be symmetrically arranged. The first frame 2 and the second frame 3 are slidably connected at one end close to the opening 5 of the receiving groove. When the first frame 2 and the second frame 3 slide relative to each other at one end close to the opening 5 of the receiving groove, at this time, the parts of the first frame 2 and the second frame 3 away from the hinge joints move away from or close to each other. Therefore, the opening 5 of the receiving groove becomes larger or smaller. By sliding, the size of the opening 5 of the receiving groove is adjusted. The structure is simple and easy to operate. Different specifications of flexible storage belts can be撑开 by adjusting the size of the opening 5 of the receiving groove, avoiding the phenomenon of the separation of the flexible storage bag from the side wall, thus avoiding the inconvenience caused by throwing garbage or other items outside the storage bag during daily life, and at the same time avoiding the increase of cleaning work.

[0042] Specifically, the first frame 2 is provided with a first side plate 21, a first plate body 22 and a second side plate 23 that are sequentially connected to form a U-shaped or approximately U-shaped structure. There are angles between the first side plate 21, the second side plate 23 and the first plate body 22. The first side plate 21 and the second side plate 23 are parallel to each other and located on the same side of the first plate body 22. The second frame 3 is provided with a third side plate 31, a second plate body 32 and a fourth side plate 33 that are sequentially connected to form a U-shaped or approximately U-shaped structure. There are angles between the third side plate 31, the fourth side plate 33 and the second plate body 32. The third side plate 31 and the fourth side plate 33 are parallel to each other and located on the same side of the second plate body 32. The first side plate 21, the first plate body 22, the second side plate 23, the third side plate 31, the second plate body 32 and the fourth side plate 33 are sequentially connected end to end to form a through groove. One end of this through groove is open and sleeved outside the tray 1 to be connected to the tray 1 to form a receiving groove. The first side plate 21 and the fourth side plate 33 are hinged at one end close to the tray 1. This hinged joint is the first hinged joint 4. At the same time, the first hinged joint 4 is located at one end where the first side plate 21 and the fourth side plate 33 are close to each other. The first side plate 21 and the fourth side plate 33 have an overlapping part at the first hinged joint 4. Screws or bolts can be used to sequentially pass through the first side plate 21 and the fourth side plate 33 to achieve the hinged connection. This first hinge axis coincides with the axis of the screw or bolt. The first side plate 21 and the fourth side plate 33 are slidably connected at one end close to the opening 5 of the receiving groove. When the first side plate 21 and the fourth side plate 33 slide relative to each other, the first plate body 22 and the second plate body 32 approach or move away from each other. The second side plate 23 and the third side plate 31 are hinged at one end close to the tray 1. This hinged joint is the second hinged joint 7. At the same time, the second hinged joint 7 is located at one end where the second side plate 23 and the third side plate 31 are close to each other. The second side plate 23 and the third side plate 31 have an overlapping part at the second hinged joint 7. Screws or bolts can be used to sequentially pass through the second side plate 23 and the third side plate 31 to achieve the hinged connection. This second hinge axis coincides with the axis of the screw or bolt. The second side plate 23 and the third side plate 31 are slidably connected at one end close to the opening 5 of the receiving groove. When the second side plate 23 and the third side plate 31 slide relative to each other, the first plate body 22 and the second plate body 32 approach or move away from each other. The relative sliding of the second side plate 23 and the third side plate 31 and the relative sliding of the first plate body 22 and the fourth plate body are carried out synchronously. At this time, the opening 5 of the receiving groove becomes larger or smaller. The size of the opening 5 of the receiving groove can be changed by sliding adjustment. The structure is simple and convenient for adjustment operation.

[0043] In the first embodiment, with respect to the setting of each guide groove and slider, on the two opposite side plates, one side plate is provided with a guide groove structure, and the other is provided with a corresponding slider structure. The first side plate 21 is provided with a plurality of first guide grooves 211 arranged at intervals, and each first guide groove 211 is arc-shaped and concentrically arranged. The center of each first guide groove 211 is located at the hinge node between the first side plate 21 and the fourth side plate 33, that is, on the first hinge axis located at the first hinge node 4. The fourth side plate 33 is fixed with a plurality of first sliders 212 corresponding to each first guide groove 211 one by one. When each first slider 212 slides in each first guide groove 211, the notch 5 of the accommodating groove becomes larger or smaller. One of the second side plate 23 and the third side plate 31 is provided with a plurality of second guide grooves, and the other is provided with a second slider 231 matching the second guide groove structure. The second slider 231 slides synchronously with the first slider 212, that is, when the first side plate 21 and the fourth side plate 33 slide relative to each other, the second side plate 23 and the third side plate 31 slide synchronously with them.

[0044] In the second embodiment, the arrangement of each guide groove and slider is different from that in the first embodiment in that both side plates are provided with guide grooves and slider structures. The first side plate 21 is provided with a plurality of first guide grooves 211 and a plurality of first sliders 212 arranged at intervals. Each of the first guide grooves 211 is arc-shaped and concentrically arranged. The center of each of the first guide grooves 211 is located at the hinge node. The fourth side plate 33 is provided with a fourth slider 332 and a fourth guide groove 331 that match each of the first guide grooves 211 and each of the first sliders 212 one by one. The guide groove 211 is concentrically arranged with each of the fourth guide grooves 331; when each of the first sliders 212 and each of the fourth sliders 332 slides in each of the first guide grooves 211 and each of the fourth guide grooves 331, the notch 5 of the accommodating groove becomes larger or smaller; one of the second side plate 23 and the third side plate 31 is provided with a plurality of second guide grooves and second sliders arranged at intervals, and the other is provided with a third guide groove and a third slider corresponding to each of the second guide grooves and second sliders one by one. When the first side plate 21 and the fourth side plate 33 slide relative to each other, the second side plate 23 and the third side plate 31 slide synchronously.

[0045] In the third embodiment, referring to Figures 1 to 4, which is different from the first and second embodiments, the first side panel and the third side panel have the same structure, and the second side panel and the fourth side panel have the same structure. The first side panel 21 is provided with a plurality of first guide grooves 211 and a plurality of first sliders 212 arranged at intervals. Each first guide groove 211 is arc-shaped and concentrically arranged. The center of each first guide groove 211 is located at the hinge node, that is, on the first hinge axis at the first hinge node 4. The fourth side panel 33 is provided with a fourth slider 332 and a fourth guide groove 331 that match each first guide groove 211 and each first slider 212 one by one. Each first guide groove 211 is concentrically arranged with each fourth guide groove 331. The second side panel 23 has the same structure as the fourth side panel 33, and the third side panel 31 has the same structure as the first side panel 21. At this time, the first frame 2 has the same structure as the second frame 3. In the production process of the side wall of the storage device, only two frames formed by the same mold can be assembled into a complete side wall main structure of the same specification, avoiding the situation where the first frame 2 and the second frame 3 with different structures need to be produced using two different molds, saving mold costs. At the same time, when one of the first frame 2 and the second frame 3 is damaged, a frame of the same specification can be randomly replaced, avoiding the problem of difficulty in replacement or high replacement cost. When each first slider 212 and each fourth slider 332 slide in the corresponding first guide groove 211 and each fourth guide groove 331, that is, when the first side panel 21 and the fourth side panel 33 slide relative to each other, the second side panel 23 and the third side panel 31 slide synchronously, and the storage groove notch 5 becomes larger or smaller.

[0046] In the third embodiment, referring to Figures 1 to 4, each first guide groove 211 and fourth guide groove 331 is provided with an arc-shaped limiting portion 2111 at one end close to the first plate body 22 and the second plate body 32, and the diameter of each limiting portion 2111 is larger than the width of each first guide groove 211 and the fourth guide groove 331, and the first slider 212 and the fourth slider 332 can preferably be elastic connecting nails, and the ends of each first slider 212 and the fourth slider 332 are provided with a first elastic body and a second elastic body, and there is an adjustable first distance between the first elastic body and the second elastic body. When the first elastic body and the second elastic body are squeezed to reduce the first distance, each first slider 212 and the fourth slider 332 can be inserted into the corresponding first guide groove 211 and the fourth guide groove 331, and the ends of each first elastic body and the second elastic body are provided with a first limiting protrusion, and the overall size of the cross section at the first limiting protrusion is larger than the overall size formed by the cross sections of the first elastic body and the second elastic body. To prevent the first slider 212 and the fourth slider 332 from falling out of the corresponding fourth guide groove 331 and the first guide groove 211, when the first elastic body and the second elastic body are not squeezed, the first spacing is greater than the diameter of the limiting portion 2111, so as to prevent the slider from falling out of the limiting portion 2111. When the storage device of this scheme is not in use, the first slider 212 and the fourth slider 332 can be slid into the limiting portion 2111. Since the radius of the limiting portion 2111 is greater than the width of each guide groove, due to the elastic effect, the first spacing between the first elastic body and the second elastic body becomes larger, so that the overall size of the slider becomes larger and is stuck in the limiting portion 2111 and cannot freely enter the smaller guide groove. At this time, the distance between the first plate body 22 and the second plate body 32 is the smallest, that is, the accommodating groove notch 5 is also the smallest, and the overall structural size of the storage device of this scheme is also the smallest, thereby reducing the space occupied by the storage device when not in use.

[0047] In the third embodiment, referring to Figures 1 to 4When using the storage device of this solution, the first elastic body and the second elastic body can be squeezed to reduce the first distance, so that each first slider 212 and the fourth slider 332 slide from the limiting portion 2111 to the corresponding fourth guide groove 331 and the first guide groove 211. At this time, due to the rebound effect of the elastic member 6, each first slider 212 and the fourth slider 332 can be automatically pushed to the corresponding fourth guide groove 331 and the first guide groove 211 away from the limiting portion 2111, thereby driving the first frame 2 and the second frame 3 to move away from each other, achieving the effect of automatic springing, thereby forming the effect of automatic opening of the accommodating groove, that is, the opening of the storage device automatically opens. The first side panel 21 and the third side panel 31 are provided with connecting holes at the first hinge node 4 and the second hinge node 7, and the second side panel 23 and the fourth side panel 33 are fixed with connecting blocks corresponding to the connecting holes at the first hinge node 4 and the second hinge node 7. The connecting blocks may preferably be elastic connecting nails. Both connecting blocks are provided with a third elastomer and a fourth elastomer. When the third elastomer and the fourth elastomer are squeezed, each connecting block can be embedded in each connecting hole, thereby realizing the hinged connection between the first frame 2 and the second frame 3. The end of each third and fourth elastomer is provided with a second limiting protrusion. The setting of the second limiting protrusion can prevent each connecting block from falling out of the connecting hole.

[0048] Specifically, the storage device with an automatically openable and adjustable opening of the present scheme also includes an elastic member 6, the two ends of the elastic member 6 are fixedly connected to the first frame 2 and the second frame 3 respectively, and the elastic member 6 is used to drive the first frame 2 and the second frame 3 to move away from each other at one end close to the receiving groove notch 5. Prestress can be applied to the elastic member 6 so that in the absence of human intervention, the first plate body 22 and the second plate body 32 at one end of the receiving groove notch 5 have a maximum distance or tend to the maximum distance. At this time, the receiving groove notch 5 has a maximum opening or tends to the maximum opening. In the absence of human intervention, the opening of the flexible storage belt can be in an expanded state, avoiding the phenomenon of the flexible storage bag being separated from the side wall, thereby causing garbage or other items to be thrown out of the storage bag when thrown away, bringing instability to life, but also increasing the cleaning work. When it is necessary to reduce the opening of the receiving slot 5, the first plate 22 and the second plate 32 can be moved closer to each other by sliding adjustment. At this time, the elastic member 6 is compressed, and the rebound effect of the elastic member 6 drives the first frame 2 and the second frame 3 away from each other, achieving an automatic pop-up effect, thereby forming an automatic opening effect of the opening of the storage device.

[0049] Specifically, a first card slot 213 is provided on the first side panel 21, and a second card slot 333 is provided on the fourth side panel 33. The two ends of the elastic member 6 pass through the first card slot 213 and the second card slot 333 respectively and are detachably fixedly connected to the first side panel 21 and the second side panel 23. The setting of the first and second card slots 333 can limit the movement of the elastic member 6 relative to the side wall in the horizontal direction, thereby preventing the elastic member 6 from bouncing away from the side wall when the elastic member 6 is compressed.

[0050] Specifically, the elastic member 6 is an elastic rod, which may preferably be an elastic steel wire rope. A bending portion 61 is provided at each end of the elastic rod. The first side panel 21 and the fourth side panel 33 are respectively provided with a first through hole 214 and a second through hole 334 that match the structure of the bending portion 61. The two bending portions 61 are respectively inserted into the first through hole 214 and the second through hole 334. The two ends of the elastic rod are bent and then inserted into the through holes to achieve the fixation of the two ends of the elastic rod. The structure is simple and easy to install and disassemble.

[0051] In one embodiment, the first clamping slot 213 and the second clamping slot 333 are opened obliquely downward and are symmetrically arranged. When the elastic rod bends upward, the accommodating slot opening 5 becomes smaller.

[0052] In another embodiment, referring to Figure 1 and Figure 3 The first card slot 213 and the second card slot 333 are opened obliquely upward and are symmetrically arranged. When the elastic rod bends downward, the accommodating slot opening 5 becomes smaller.

[0053] Specifically, the tray 1 is provided with a collection trough, with the collection trough opening 11 facing the direction of the receiving slot opening 5. The collection trough structure is in the shape of a wide-mouthed disk, with the vertices of each of the four corners being chamfered in an arc shape. The size of the collection trough opening 11 can be selected based on the size of the opening of the side wall away from the receiving slot opening. When the flexible storage bag ruptures, the items stored therein can fall onto the tray 1. The provision of the collection trough can collect a certain amount of items, thereby preventing items that fall onto the tray 1 from falling onto the ground and causing dirt on the ground, thereby avoiding increased cleaning work.

[0054] Specifically, the first frame 2 and the second frame 3 are fixedly connected to a support plate at one end near the tray 1, and the height of each support plate in the vertical direction is equal to the height of the tray 1. The support plates on the same side as the first plate 22 and the second plate 32 have an angle with the outer surface of the first plate 22 and the second plate 32, and the angle is less than 180°. When the notch of the storage slot becomes larger, the cross-section formed by the support plate is larger than the cross-section area of ​​the side wall near the tray 1, thereby making the overall structure of the storage device more stable. The storage device with an automatically openable and adjustable opening of this solution also includes a bottom plate, which has a plate body fixedly connected to each support plate. The bottom plate and the edge of the side wall form a third opening. The size of the third opening is smaller than the structural size of the tray 1, which can prevent the tray 1 from falling out of the third opening and separating from the side wall when the storage device is moved or lifted.

[0055] For other details of the storage device with an automatically opening and adjustable opening described in the present invention, please refer to the prior art and will not be described in detail here.

[0056] The above description is merely a preferred embodiment of the present invention and does not constitute any form of limitation to the present invention. Therefore, any modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of the technical solution of the present invention.
