Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of folding storage, especially relates to a folding frame and a storage cabinet with a built-in vacuum bag. BACKGROUND

[0002] The storage basket is a multifunctional household container, and its large capacity design can meet the needs of various life scenes: it can be used as a dirty clothes basket to temporarily store dirty clothes, and can also be used as a sports equipment storage box to store basketballs, yoga mats, foam shafts and other bulky items. In order to adapt to the storage needs of large items, such containers usually adopt a spacious box structure design, but the volume problem caused thereby is particularly obvious in the transportation and storage link - under the conventional form, the occupied space is relatively large, which is not conducive to logistics loading and space storage when idle.

[0003] The X-shaped folding mechanism is a common folding way for existing storage baskets, but the X-shaped folding mechanism of the conventional storage basket is prone to jamming when folding, which is not conducive to user folding. INVENTION CONTENTS

[0004] In order to solve the problems in the prior art, a storage basket that can be conveniently folded and stored is provided.

[0005] The utility model adopts the following technical scheme to be realized: a folding storage basket, comprising:

[0006] A top frame in a ring-shaped hollow structure;

[0007] A bottom plate parallelly arranged below the top frame and used for supporting articles;

[0008] Four groups of X-shaped folding frames cross-hinged and symmetrically distributed between the top frame and the bottom plate to form a side wall support structure of the storage basket, the hinge center of each X-shaped folding frame is provided with an elastic member to maintain its unfolded state by elastic force, and the upper and lower ends are respectively hinged to the top frame and the bottom plate;

[0009] Among them, the upper and lower end hinge parts of two groups of X-shaped folding frames are matched with double sliding groove structures, the top frame and the bottom plate are respectively provided with two horizontally and spaced first sliding grooves, and the two hinge parts at the upper and lower ends of the X-shaped folding frame are slidably arranged in the first sliding grooves;

[0010] The upper and lower end hinge parts of the other two groups of X-shaped folding frames are matched with single sliding groove structures, the top frame and the bottom plate are respectively provided with a single second sliding groove, one hinge part at the upper and lower ends of the X-shaped folding frame is slidably arranged in the second sliding groove, and the other hinge part is fixedly hinged to the top frame or the bottom plate.

[0011] In use, the elastic members of the hinge centers of the X-shaped folding frames maintain the X-shaped folding frames in an unfolded state in a natural state, so that the user can place the articles in the storage basket, and the four groups of X-shaped folding frames act as four side walls of the storage basket, which can ensure ventilation and block the articles, so that the articles are located in the storage basket. When not in use, the user can directly press the top frame downward, so that the top frame is close to the bottom plate, so that the volume of the entire storage basket is reduced. After the volume of the storage basket is reduced, the storage basket can be tied by a rope or stacked with other frames having a weight on the storage basket, so that the storage basket does not restore and pop up.

[0012] In actual use, in order to reduce the jamming of the X-shaped folding frames when the user folds the storage basket, two groups of X-shaped folding frames are matched with double sliding groove structures, so that the freedom degree of the storage basket is higher when being folded. In order to ensure the stability when being folded, the other two groups of X-shaped folding frames are matched with single sliding groove structures.

[0013] The X-shaped folding frame, the top frame and the bottom plate are used to form the storage basket. The storage basket can be naturally unfolded in use, and can be folded by itself when not in use or during transportation, so as to reduce the volume, facilitate logistics loading and space storage when idle, and adopt single and double sliding groove structures, which can ensure stability and improve freedom degree, so as to reduce jamming when being folded.

[0014] Preferably, at least two ends of the first sliding groove and the second sliding groove are mechanical stop portions, and the two mechanical stop portions correspond to the fully unfolded state and the fully folded state of the storage basket, respectively.

[0015] When the hinge part slides to abut against the mechanical stop portion, the hinge part cannot continue to slide, and the final unfolding or final folding state of the X-shaped folding frame is reached, so that the fully unfolded state and the fully folded state of the storage basket are reached. The fully unfolded state refers to that the distance between the top frame and the bottom plate reaches the maximum support height; the fully folded state refers to that the distance between the top frame and the bottom plate reaches the minimum storage thickness.

[0016] Preferably, opposite sides of the top frame and the bottom plate are provided with vertically extending abutting convex columns. When the abutting convex columns of the top frame and the bottom plate abut against each other, the storage basket reaches the fully folded state.

[0017] The storage basket needs external force when being folded. By setting the mutual abutment of the abutting convex columns, it is ensured that the top frame of the storage basket will stop after descending to a certain height. If only the abutment of the hinge part and the mechanical stop portion is used to reach the fully folded state, the hinge part and the mechanical stop portion of the sliding groove are easily deformed due to excessive external force. Therefore, by setting the abutting convex columns, the sliding groove and the hinge part can be more safely protected.

[0018] Preferably, the abutting convex columns are arranged at the corners of the top frame and the bottom plate, and the first sliding groove and the second sliding groove are arranged between two adjacent abutting convex columns.

[0019] The abutting convex columns are arranged at the corners of the top frame and the bottom plate, so as not to interfere with the X-shaped folding frame.

[0020] Preferably, the two groups of X-shaped folding frames with the double sliding groove structure are arranged oppositely, and the two groups of X-shaped folding frames with the single sliding groove structure are arranged oppositely.

[0021] The X-shaped folding frames with the double sliding groove structure and the single sliding groove structure are arranged oppositely, so that the stability of the entire storage basket can be better.

[0022] Preferably, the top frame and the bottom plate each correspondingly have a long side and a short side, the X-shaped folding frame arranged at the short side includes three groups of X-shaped folding rods hingedly connected in sequence, and the X-shaped folding frame arranged at the long side includes two groups of X-shaped folding rods hingedly connected in sequence.

[0023] The length of the short side is shorter than that of the long side, so the X-shaped folding rod cannot be made too long, and therefore three groups of X-shaped folding rods hingedly connected in sequence can be adapted to the short side. Similarly, since the length of the long side is relatively long, the length of the X-shaped folding rod can also be relatively long, and therefore two groups of X-shaped folding rods hingedly connected in sequence can meet the folding requirement.

[0024] Preferably, the hinge part includes a pin shaft rotationally connected with the X-shaped folding rod, the pin shaft passes through the first sliding groove and the second sliding groove respectively, and the pin shaft is in sliding fit with the first sliding groove and the second sliding groove respectively.

[0025] A storage cabinet includes the folding storage basket and a vacuum bag, the vacuum bag is arranged between the top frame and the bottom plate and located at the inner side of the X-shaped folding rod, the bottom of the vacuum bag is fixedly connected with the bottom plate, the opening periphery of the top frame is fixedly connected with the bag opening of the vacuum bag by welding or bonding, so that the opening of the top frame serves as the outline of the bag opening of the vacuum bag, the top frame is detachably fixed with a cover plate for plugging the opening of the top frame, and the top frame or the vacuum bag is provided with an air nozzle for connecting with a vacuum device.

[0026] When the cover plate plugs the opening of the top frame, the vacuum bag forms a sealed chamber, and when the vacuum bag is vacuumed, the X-shaped folding frame slowly descends under the action of atmospheric pressure, so that the entire storage basket is folded.

[0027] The storage basket is matched with a vacuum bag, the upper and lower ends of the vacuum bag are fixed with the top frame and the bottom plate, so that the top frame and the bottom plate can support the whole bag body, thereby facilitating the placing of clothes or bedding. After the clothes or bedding are placed, the vacuum bag can be subjected to vacuumizing operation, so that the contraction of the vacuum bag drives the folding of the storage basket, the storage basket has an overall frame, provides three-dimensional support and protection for the vacuum bag, prevents the bag body from being deformed under pressure, and guarantees the regularity of the storage space. And the X-shaped folding frame matched with the double sliding groove and single sliding groove structure can guarantee the stability of the top frame when descending.

[0028] Compared with the prior art, the utility model has the advantages that: the X-shaped folding frame, the top frame and the bottom plate constitute the storage basket, the storage basket can be naturally unfolded in use, and is folded in itself when not in use or during transportation, so that the volume is reduced, and the space storage is facilitated when idle; and the single-double sliding groove structure is adopted, the stability is guaranteed, the degree of freedom is improved, and the jamming during folding is reduced.
