Description

Technical Field

[0001] The utility model relates to the technical field of drying racks, in particular to a folding structure and a butterfly-shaped drying rack using the folding structure. Background Art

[0002] There are various types of floor-standing drying racks on the market. For example, they can be divided into wing-shaped, "X"-shaped, single-pole, double-pole, and folding types according to the structure. Considering people's demand for residential space, most types have folding functions. The folding methods and styles after folding are different for different structures of different sizes, and the folding function will more or less affect the overall stability of the drying rack. In life, people's most important requirements for floor-standing drying racks are: 1. Stability, 2. Practicality and convenience, 3. The size of the space occupied by folding and storage. With the rapid development of e-commerce, the convenience of product transportation is also one of the main considerations in structural design.

[0003] The wing-shaped drying rack can also be called a butterfly-shaped drying rack. As shown in patent documents with publication numbers CN205443701U, CN215856837U, CN204162926U, CN305653305S, etc., the structure of the existing wing-shaped clothes drying rack is roughly as follows: it includes symmetrically arranged supporting feet and drying wings, the supporting feet and the drying wings are connected by a through-connecting shaft, the drying wings can be flipped to a roughly horizontal position relative to the supporting feet, and then clothes can be dried on the drying wings. When not in use, the drying wings can be flipped relative to the supporting feet to fit therewith to save space.

[0004] However, the drying wings of the existing wing-shaped clothes drying racks are generally fixed frame structures. Even in a fully folded state, they can only save space in the left and right directions (i.e., the length direction) at most, but cannot save space in the width direction. Utility Model Content

[0005] The purpose of the utility model is to provide a folding structure which can at least solve one of the above problems.

[0006] According to one aspect of the utility model, a folding structure is provided, comprising at least:

[0023] According to another aspect of the utility model, a butterfly-shaped drying rack is provided, comprising a supporting portion and a drying portion, wherein the drying portion is mounted on the upper end portion of the supporting portion, and the drying portion is the above-mentioned folding structure.

[0024] Therefore, the butterfly-shaped drying rack of the utility model applies the above-mentioned folding structure, which can realize overall folding and folding, which can at least facilitate storage, handling, delivery, transportation and the like, and the entire folding process does not require disassembly of parts, and the operation is simple and quick.

[0025] In some embodiments, the support portion includes a pair of support frames, the upper ends of the pair of support frames are respectively connected to a pair of connecting components, and each support frame includes a pair of parallel support rods, and the upper ends of the support rods are connected to corresponding connecting components.
