Description

Technical Field

[0001] The utility model relates to the technical field of storage bags, in particular to a foldable and expandable large-capacity storage bag for a bed bottom. Background Art

[0002] In our daily life, storage bags are very convenient to use. Due to the high housing prices, the area of ​​personal residences in modern society is generally small, and the use of storage bags is becoming more and more popular. They can save space very well. For example, we can place storage bags under the bed and other places that are not often used.

[0003] However, in the process of placing items, the existing storage bags cannot reasonably arrange the placement of items like boxes, which makes it very inconvenient to take out the items you want from under the bed. The simple hard box structure has a fixed size and is inconvenient to store when not in use.

[0004] Therefore, in order to solve the problem that the existing storage bags and storage boxes cannot reasonably arrange the placement of items and cannot be folded and shrunk to reduce the volume, a storage bag that can be folded and shaped is designed to facilitate the adjustment of the placement of items and convenient folding and storage when not in use. Utility Model Content

[0005] In order to overcome the problem that existing storage bags and storage boxes cannot reasonably arrange the placement of items and cannot be folded and shrunk to reduce the volume.

[0006] The technical solution of the utility model is: a foldable and expandable large-capacity storage bag under the bed, including a cloth bag and a rubber positioning ring; also including a base, a rotating shaft and a rotating handle; the two sides of the cloth bag are fixedly connected with the rubber positioning rings, and the rubber positioning rings are symmetrically arranged with the center of the cloth bag as the axis, the base is placed on the upper surface of the bottom surface inside the cloth bag, and the two ends of the base are provided with cylindrical through-type holes for the rotating shaft to pass through, one end of the rotating shaft is a cylindrical protrusion, and the bottom diameter of the cylindrical protrusion of the rotating shaft is larger than the inner diameter of the cylindrical through-type hole of the base, the other end of the rotating shaft is provided with a threaded hole, and the threaded hole of the rotating shaft is threadedly connected to one end of the rotating handle, a folding structure is provided above the base, and a telescopic mechanism is provided between the two bases.

[0007] Preferably, after the folding mechanism is unfolded, the cloth bag is unfolded into a box shape, so that the placement of items can be reasonably arranged like a box, avoiding the problem of messy placement of items, and making it convenient to take out the objects you want from under the bed. When you need to move, you can fold the folding mechanism to facilitate carrying. The telescopic mechanism can change the space occupied. The overall length of the connecting rod one and the connecting rod two can be set according to your needs to change the width, so that multiple devices can be placed under the bed to better achieve classification.

[0008] Preferably, the folding mechanism comprises a support plate one, a positioning rod, a positioning ball, a rotating shaft two, a connecting arm one, a connecting shaft, a connecting arm two, a support plate two and a hanging rod, the supporting plate one is rotatably connected to the rotating shaft one, one side of the upper end of the supporting plate one is fixedly connected to the positioning rod, the end of the positioning rod is fixedly connected to the positioning ball, one side of the upper end of the supporting plate one is fixedly connected to the rotating shaft two, the connecting arm one is rotatably connected to the rotating shaft two, one end of the connecting arm one is fixedly connected to the connecting shaft, the connecting arm two is rotatably connected to the connecting shaft, one side surface of the base is rotatably connected to the supporting plate two, one side of the upper end of the supporting plate two is fixedly connected to the hanging rod, the supporting plate one and the supporting plate two are unfolded to 90 degrees, and then the connecting arm two is rotated and extended from the connecting arm one, and the arc-shaped opening of the connecting arm two is engaged with the hanging rod, thereby completing the unfolding of the folding mechanism.

[0009] Preferably, the telescopic mechanism includes: connecting rod one, connecting rod two and a positioning handle. Connecting rod one is fixedly connected to one side surface of the base, and connecting rod two is fixedly connected to one side surface of the other base. Connecting rod two is provided with a groove, and the groove of connecting rod two is slidably connected to connecting rod one. Connecting rod two is threadedly connected with a positioning handle. The distance between the two bases is changed by changing the overall length of connecting rod one and connecting rod two, thereby changing the width after expansion. After setting the length, the positioning handle is tightened to tighten the connection between connecting rod one and connecting rod two.

[0010] Preferably, one side surface of support plate 1 and support plate 2 is provided with a hole for rotating shaft 1 to pass through, the diameter of the positioning rod is the same as the inner diameter of the rubber positioning ring, the diameter of the positioning ball is larger than the inner diameter of the rubber positioning ring, and the rubber positioning ring on the cloth bag is passed through the positioning ball. The positioning ball prevents the cloth bag from detaching from the positioning rod, which facilitates the shaping of the cloth bag when it is unfolded and retracted.

One end of the connecting rod is a columnar protrusion, and the diameter of the columnar protrusion of the hanging rod is larger than the diameter of the hanging rod. The opening of the connecting arm 2 facilitates the connecting arm 2 to be hung on the hanging rod, so that the unfolded structure is formed and prevents the connecting arm 2 from detaching from the hanging rod.

[0013] Preferably, a cylindrical through-type threaded hole is provided on the upper end of the surface of connecting rod 2, and a wavy pattern is provided on the surface of the positioning handle. The threaded hole of connecting rod 2 facilitates the positioning handle to connect connecting rod 2 with connecting rod 1 through friction, and the wavy pattern on the surface of the positioning handle can play an anti-slip role, making it convenient to tighten the positioning handle.

[0014] The beneficial effects of the utility model are:

[0015] 1. After the folding mechanism is unfolded, the cloth bag is unfolded into a box shape, so that the placement of items can be reasonably arranged like a box, overcoming the problem that the existing storage bags cannot reasonably arrange the placement of items. When moving is needed, the folding mechanism is folded for easy carrying. The utility model has the advantages that the box can reasonably place the internal items, and the storage bag is easy to fold and close, which is convenient for carrying.

[0016] 2. It can be better classified and placed. The size of the area under the bed is different. The overall length of the connecting rod 1 and the connecting rod 2 can be determined according to the specific area of ​​the bed bottom to change the occupied space of the utility model. Therefore, when placing multiple new storage bags, the space can be better arranged. When classifying, the items that occupy more space have a larger width, and the items that occupy less space have a smaller width. BRIEF DESCRIPTION OF THE DRAWINGS
