Description

Technical Field

[0001] The utility model relates to the technical field of drying racks, in particular to a synchronous telescopic sleeve and a drying device applying the same. Background Art

[0002] There are various floor-standing drying racks on the market at present. Structurally, they can be divided into wing-shaped, "X"-shaped, single-rod, double-rod, and folding types. Considering people's demand for residential space, most types are provided with a folding function. Different structures have different sizes, folding methods, and styles after folding. The foldable 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: first, stability; second, practical convenience; third, the size of the space occupied by folding and storing. With the rapid development of e-commerce, the convenience of product transportation is also one of the main factors considered in the structural design.

[0003] The "X"-shaped drying rack is a relatively traditional and popular floor-standing drying rack.

[0004] As shown in the Chinese utility model patent with the publication number of CN 207512444 U, the structures of existing "X"-shaped drying racks are generally as shown in this patent, including two parallel horizontal drying rods and an X-shaped folding frame connecting the two horizontal drying rods. The X-shaped folding frame can be closed to make the two horizontal drying rods approach each other, or can be opened to make the two horizontal drying rods move away from each other.

[0005] In order to expand the drying space, existing manufacturers generally set the two horizontal drying rods as a telescopic sleeve structure, and increase the horizontal length by taking out the inner tube, thereby increasing the drying space in the horizontal direction. However, in the prior art, only one side of the telescopic inner tube can be adjusted at a time, and there is room for improvement. Summary of the Utility Model

[0006] The purpose of the present utility model is to provide a synchronous telescopic sleeve, which can at least solve one of the above problems.

[0007] According to one aspect of the present utility model, there is provided a synchronous telescopic sleeve, which at least includes:

[0008] An outer tubular member;

[0009] A first inner tubular member, sleeved inside the outer tubular member and located at the first end of the outer tubular member;

[0011] A linkage mechanism, installed inside the outer tubular member and in linkage cooperation with the first inner tubular member and the second inner tubular member;

[0012] When the first inner tubular member moves relative to the outer tubular member, the second inner tubular member moves in linkage under the action of the linkage mechanism, and the first inner tubular member and the second inner tubular member approach or move away from each other;

[0013] Alternatively, when the second inner tubular member moves relative to the outer tubular member, the first inner tubular member moves in linkage under the action of the linkage mechanism, and the first inner tubular member and the second inner tubular member approach or move away from each other.

The first linkage rod is fixedly connected to the first inner tubular member, the second linkage rod is fixedly connected to the second inner tubular member, and the linkage member is rotatably mounted on the outer tubular member and is in linkage cooperation with the first linkage rod and the second linkage rod respectively.

[0015] In some embodiments, the linkage member is a gear, the first linkage rod and the second linkage rod are racks, the first linkage rod and the second linkage rod are oppositely arranged and parallel to each other, and the linkage member is in transmission cooperation with the first linkage rod and the second linkage rod respectively.

[0016] In some embodiments, the linkage mechanism further includes a connecting shaft, and the linkage member is rotatably sleeved in the outer tubular member through the connecting shaft.

[0017] In some embodiments, the synchronous telescopic sleeve further includes a first connecting member, and the first connecting member is sleeved in the first inner tubular member and fixedly connected to the first linkage rod.

[0018] In some embodiments, the synchronous telescopic sleeve further includes a second connecting member, and the second connecting member is sleeved in the second tubular member and fixedly connected to the second linkage rod.
