[0025] In order to make the purpose, technical scheme and advantages of the utility model more clearly, the utility model is further described in detail below in combination with the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.
[0026] It can be understood that the terms "first", "second" and the like used in the present application can be used herein to describe various elements, but unless specifically stated, these elements are not limited by these terms. These terms are only used to distinguish the first element from another element.
[0027] It should be noted that the "fixed" or "fixedly arranged" proposed in the present application can be considered as a combination of one or more of nut connection, adhesion, insertion, welding and integral molding, unless otherwise specified. These different fixing methods all belong to the general technology well known in the art.
[0028] In one embodiment, as shown in Figures 1-4 A folding structure is proposed, which comprises a fixing frame 100, two connecting pieces 200 and a support frame 300, the two connecting pieces 200 are symmetrically fixedly arranged on the fixing frame 100; the support frame 300 is an open type telescopic support frame, and two ends are provided with curved rods 310 which are symmetric to each other; the connecting piece 200 is provided with a folded edge 211 and a through hole 212, the folded edge 211 and the through hole 212 are not in the same plane, one end of the curved rod 310 is rotationally connected with the through hole 212, and the other end is arranged between the folded edge 211 and the fixing frame 100.
[0029] In the present embodiment, the support frame 300 is telescopic, and two ends are symmetrically provided with curved rods 310; by compressing or expanding the support frame 300, the end of the curved rod 310 is conveniently inserted into the through hole 212, and installation and disassembly are more convenient; the folded edge 211 plays a role of fixing and limiting. The folding structure of the present embodiment has few parts, and installation and maintenance are quite convenient. After unfolding, the folded edge 211 stably limits the position of the curved rod 310, is fixedly reliable, and is convenient for folding and storage.
[0030] In the present embodiment, the fixing frame 100 plays a role of supporting and fixing, and the fixing frame 100 itself can be an integral structure or a split structure.Figure 1 The split fixing frame 100 is provided, which includes two fixing rods that can be fixedly installed on a wall surface, a support plate or a storage plate. It can be understood that the fixing frame of an integrated structure is to connect the two fixing rods. The connecting piece 200 plays a role of positioning support and rotation limiting.
[0031] The embodiment needs to be explained for the "open telescopic support". The structure is an open structure, and its shape includes but is not limited to V-shaped, W-shaped, U-shaped or concave-shaped, that is, as long as the characteristics of "open opening" and compressible and expandable are met, it can be regarded as the "open telescopic support" described in the embodiment. The support frame 300 can be selected from steel or plastic and other elastic conventional materials. The installation mode of the support frame 300 depends on the installation direction of the connecting piece 200. As shown in Figure 1 and 2 , the support frame 300 needs to be expanded outwardly when installing and dismounting the support frame 300; it can be understood that if the connecting piece 200 is installed by turning 180 degrees, the corresponding support frame 300 needs to be squeezed inwardly to be installed and dismounted.
[0032] In an optimization scheme, as shown in Figure 1 and 2 , the folding structure has two groups, and is symmetrical to each other, and two groups of the folding structure share the same fixing frame 100. The structure divides the fixing frame 100 into two fixing rods, and has fewer components and simple structure.
[0033] In an optimization scheme, as shown in Figure 3 and 4 , the connecting piece 200 includes a first connecting piece 210 and a second connecting piece 220, the first connecting piece 210 is provided with the folding edge 211 and the through hole 212, and the folding edge 211 is connected with the first connecting piece 210 through a smooth curved edge. The first connecting piece 210 is fixedly inclined to the second connecting piece 220, and the second connecting piece 220 is fixedly connected with the fixing frame 100. The curved rod 310 includes a first straight rod 311 and a second straight rod 312, the first straight rod 311 and the second straight rod 312 are fixedly inclined, the first straight rod 311 is inserted into the through hole 212 and rotationally connected with the through hole 212, and the second straight rod 312 is arranged in a space surrounded by the folding edge 211, the first connecting piece 210 and the second connecting piece 220. One side of the folding edge 211 with a long edge is close to the second straight rod 312.
[0034] In the optimization scheme, as shown in Figure 3As shown, the curved rod 310 is in the shape of "7" as a whole, the first connecting piece 210 is perpendicular to the second connecting piece 220, the folded edge 211 is perpendicular to the first connecting piece 210, and the folded edge 211, the first connecting piece 210 and the second connecting piece 220 enclose a "concave" space for placing the second straight rod 312 of the curved rod 310. The folded edge 211 and the first connecting piece 210 are connected by a smooth curved edge, which facilitates the unfolding of the support frame 300 from inside to outside.
[0035] In one embodiment, as shown in Figure 5 and 6 As shown, a storage rack is provided, which comprises a storage plate 400 and at least two sets of the folding structure described in the above embodiments, the folding structures are symmetrically arranged, and the fixing frame 100 of the folding structure is arranged at the bottom of the storage plate 400.
[0036] In this embodiment, the storage rack is used for placing daily necessities, and the folding structure at the bottom plays a role of lifting and supporting after being unfolded. The specific structure and role of the folding structure are not described here. The working principle of the storage rack of this embodiment is as follows:
[0037] As shown in Figure 5 When installed, the fixing frame 100 is fixedly installed at the bottom of the storage plate 400, and then the four connecting pieces 200 are symmetrically installed at the four corners of the fixing frame 100 through threaded connection; the support frame 300 is pried outward, and the curved rod 310 at both ends of the support frame 300 is inserted into the through hole 212. When unfolded, the support frame 300 is pulled, the first straight rod 311 of the curved rod 310 rotates in the through hole 212, the second straight rod 312 smoothly passes through the smooth curved edge on one side of the folded edge 211, and then is embedded in the space enclosed by the folded edge 211, the first connecting piece 210 and the second connecting piece 220. When folded, the support frame 300 is pried outward, so that the second straight rod 312 is separated from the folded edge 211 and returns to the original position.
[0038] The above-described embodiments only express several implementation manners of the present application, and the description is relatively specific and detailed, but it should not be understood as a limitation on the scope of the present application. It should be pointed out that, for ordinary skilled persons in the art, without departing from the concept of the present application, a number of modifications and improvements can be made, which all belong to the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the appended claims.
[0039] The above-described only is the preferred embodiment of the present application, and does not limit the present application, and any modification, equivalent replacement and improvement made within the spirit and principle of the present application should be included in the protection scope of the present application.
