Description

Technical FieldThe present application relates to the technical field of folding baskets, and more particularly to a folding sleeping basket.Background ArtThe sleeping basket on the baby carriage is convenient to push the baby on travel. In order to facilitate travel, most current baby carriages and sleeping baskets are designed to be folded, facilitating carrying or loading. The conventional folding method for baby baby cars is generally to fold them up and down in the vertical direction to make them flat, which is convenient for subsequent packing or loading and carrying. However, in this folding method, only the spatial dimensions in the up and down direction change, and the left and right lengths cannot be changed. The conventional sleeping basket is still very long after being folded together and the packaging takes up a lot of space, which makes later transport or later wear more difficult. In addition, the existing folding process is controlled via two-sided keys, which makes the operation awkward.Therefore, the object of those skilled in the art must be able to achieve urgent resolution is to change the existing up-and-down folding method to provide a folding sleeping basket with a new folding method which is easy to operate and requires little space after folding.Subject of the Utility ModelIn view of this, the present application provides a foldable sleeping basket that changes the traditional folding method of the sleeping basket in up and down directions and instead is folded in the left and right directions to reduce the overall length and size of the folding space of the sleeping basket so that it is easier to package or carry outside.In order to achieve the above-mentioned purpose, according to the technical solution of the present application, there is provided a foldable sleeping basket comprising:Support rod receivers, wherein two groups of support rod receivers are provided and are arranged at intervals, wherein a plurality of transverse support rods are firmly connected between the two groups of support rod receivers, and a bent bottom rod is connected in articulated fashion on each of the two end sides of the two groups of support rod receivers;Inclined support rods, wherein the inclined support rods are arranged in groups of two and are symmetrically hinged to the support rod receiver, a connecting rod between the inclined support rods and the bottom rod is hinged to the same end side of the support rod receiver, and the support rod receiver and the inclined support rod on the same end side, the connecting rod and the bottom rod form a first four-bar linkage;A mounting bar, wherein two groups of mounting bars are provided and both are bent bars, the two groups of mounting bars are arranged one to one and over the two groups of bottom bars, the ends of the two groups of mounting bars are hingedly connected, the upper ends of the inclined support bars are hingedly connected to the mounting bars on the corresponding side, the two groups of inclined support bars on the same support bar receiver, and the mounting bars form a second four-bar linkage, wherein the second four-bar linkage is a control end and is hinged for changing the deformation state of the first four-bar linkage;a handle, wherein the handle is hinged to a junction of two groups of the enclosure rods.The technical effect achieved by the sleeping basket according to the present application is: this product realizes the folding deformation of the sleeping basket based on the cooperation of two basic four-joints. The second four-bar linkage controls the folding and folding of the first four-bar linkage, and the inclined support rod provides a deformation basis for folding the two sides of the second four-bar linkage.
