TECHNICAL FIELD

The present utility model relates to a supporting and locking structure for a cloth frame, and pertains to the technical field of articles for daily use.

BACKGROUND

Cloth frames are mainly used for accommodating and storing articles. As spring goes and autumn comes, storage cloth frames always lie idle in this or that season. However, the existing storage cloth frames cannot be folded, and therefore take up a lot of space. There is an urgent need for a cloth frame that is foldable and can realize three-dimensional support when in use. The foldable cloth frame structure on the market has a complex design, with a cloth frame opening and a hard positioning frame stuck and fixed together by glue. This structure neither is environmentally friendly enough nor meets people's usage needs.

SUMMARY

Given the above problems, the technical problem to be solved by the present utility model is to provide a supporting and locking structure for a cloth frame.

A supporting and locking structure for a cloth frame in the present utility model comprises a hard base, a cloth frame, a positioning frame, supporting structures, a flip cover, and lifting openings. The cloth frame is fixed on the hard base. The positioning frame is fixed at a cloth frame opening of the cloth frame. Four supporting structures are arranged between the hard base and the positioning frame. The flip cover is sewn on one side on the cloth frame. The lifting openings are arranged on left and right ends of the cloth frame.

As a preferred option, the cloth frame is designed with a soft structure, with loop fasteners sewn at four corners on an upper inner side of the cloth frame. Protective belts are sewn at four corners that are located on the hard base under the cloth frame. Hook fasteners are arranged on one end of the protective belts and stuck to the four loop fasteners on the upper inner side of the cloth frame.

As a preferred option, the positioning frame consists of a positioning subframe and a positioning parent frame. A locking convex edge on an outer side of the positioning subframe is fixedly connected to edges of the cloth frame opening of the cloth frame through a sewing machine. A plurality of locking grooves are arranged on a convex wall on an inner side of the positioning subframe. Locking barbs are fixed in the locking grooves, and fixedly connected to a plurality of positioning grooves on an inner side at a bottom portion of the positioning parent frame. The locking convex edge on the outer side of the positioning subframe is clamped in the locking grooves at a lower portion of the positioning parent frame, while the locking barbs are clamped and fixed in the positioning grooves. A flip cover positioning groove is arranged on the positioning parent frame. When the flip cover is locked, it is just clamped in the flip cover positioning groove.

As a preferred option, the supporting structure consists of a first supporting leg, a second supporting leg, a first protective cover, a second protective cover, a positioning sleeve, and an elastic band. The first supporting leg and the second supporting leg are designed with hollow structures. The first supporting leg and the second supporting leg have supporting portions, on which the first protective sleeve and the second protective sleeve are fixed. The positioning sleeve is fixed on the first supporting leg. The elastic band is fixed between the first supporting leg and the second supporting leg. The first supporting leg and the second supporting leg can be folded and stored. The elastic band plays a folding role. As the first supporting leg and the second supporting leg are pulled apart, they can be pulled by means of the elasticity of the elastic band to reset and combine with each other, so that the second supporting leg is clamped in the positioning sleeve, and the first supporting leg and the second supporting leg are fixed in the shape of I.

As a preferred option, the supporting structure has an upper end and a lower end that abut against the hard base on an inner side of the cloth frame and a positioning frame bottom of the positioning subframe through the first protective sleeve and the second protective sleeve, respectively.

The present utility model has the following beneficial effects: it is featured with reasonable structure design, beautiful appearance, novel and unique shape, simple operation, convenient utilization, and glue-free fixation; as clamping is adopted as the fixing manner, it is not only simple in production process, but also environmentally friendly for consumers to use; as the three-dimensional support is realized through the supporting structures, it is flatter and more stereoscopic when articles are placed therein; as the lifting openings are arranged on the left and right sides of the cloth frame, it is convenient for people to take, which meets consumers' usage needs.

Four supporting structures 4 are arranged between the hard base 1 and the positioning frame 3, which makes it more stereoscopic when unfolded. The flip cover 5 is sewn on one side on the cloth frame 2. The lifting openings 6 are arranged on left and right ends of the cloth frame 2.

The cloth frame 2 is designed with a soft structure, can be unfolded to accommodate articles, and therefore becomes flatter and more stereoscopic. Loop fasteners 21 are sewn at four corners on an upper inner side of the cloth frame 2. Protective belts 22 are sewn at four corners that are located on the hard base 1 under the cloth frame 2. Hook fasteners 221 are arranged on one end of the protective belts 22 and stuck to the four loop fasteners 21 on the upper inner side of the cloth frame 2.
