Detailed Description

Exemplary embodiments of the present invention will be described in detail below with reference to the accompanying drawings. These exemplary embodiments are provided so that those skilled in the art can clearly understand the present invention and can implement the present invention according to the description herein. The drawings and detailed description are not intended to limit the invention, which is defined by the appended claims.

As shown in fig. 1 and 2, a support frame comprises main spoke, fixed plate, a plurality of vice spokes, be provided with a plurality of rotation axes on the fixed plate, main spoke, vice spoke pass through the rotation axis and are connected with the fixed plate, under support frame fold condition: the main spoke and the fixed plate form an included angle of 90 degrees, and the supporting frame is in a fully-unfolded or semi-unfolded state: the main spokes and the fixed plate form an included angle of 180 degrees; the auxiliary spokes rotate around the fixed plate in the opposite direction (anticlockwise), and fixed included angles are formed between the auxiliary spokes and the main spokes, so that the support frame is in a semi-unfolded state; the auxiliary spokes rotate around the positive direction (clockwise) of the fixing plate, and the maximum included angles are formed among the auxiliary spokes and between the auxiliary spokes and the main spokes, so that the supporting frame is in a fully-unfolded state;

fixed included angles are formed among the auxiliary spokes and between the auxiliary spokes and the main spokes, the total unfolding angle between the auxiliary spokes and the main spokes is smaller than 90 degrees, and the auxiliary spokes are enabled to keep the tendency of toppling towards the main spokes under the action of the gravity of the auxiliary spokes, so that the structural stability of a half-unfolding state is realized;

maximum included angles are formed between the auxiliary spokes and the main spokes, and the structural stability of the fully unfolded state is realized by the tension limitation of the mosquito net and the gravity of the spokes;

as shown in fig. 4, because the rotating shafts on the fixing plates are arranged in a stepped manner at the horizontal position, the horizontal height of the rotating shafts connecting the auxiliary spokes is sequentially reduced, the auxiliary spokes rotate in the opposite direction around the fixing plates, the auxiliary spokes and the main spokes are mutually limited to form a fixed included angle, and an angle limiting device is arranged between the main spokes and the fixing plates to switch and keep locking the included angle between the main spokes and the fixing plates between 90 degrees and 180 degrees, if the included angle between the fixing plates cannot be kept locked between 180 degrees, the auxiliary spokes can generate torsion to the fixing plates under the action of gravity, so that the fixing plates are turned over towards the main spokes, and the semi-unfolding state cannot be kept stable.

Alternatives may also be employed: the diameters of the rotating heads of the auxiliary spokes are sequentially reduced, and the same effect can be generated by sequentially reducing the horizontal height of the rotating shaft by adopting the mode;

the purpose is to limit the rotation angle by making the sub spokes interfere with each other.

As shown in fig. 6, an angle limiting device is arranged between the main spoke and the fixing plate, so that an included angle between the main spoke and the fixing plate is switched between 90 degrees and 180 degrees and is kept locked;

the main spokes are provided with a plurality of salient points which are arrayed around the rotating shaft and used for limiting the angle between the main spokes and the fixing plate;

the fixing plate is provided with a plurality of grooves which are arrayed around the rotating shaft and used for limiting the angle between the fixing plate and the main spokes;

the salient points and the grooves are matched and the material elasticity is utilized to generate resistance, so that the included angle between the main spoke and the fixing plate is switched between 90 degrees and 180 degrees and is kept locked, and when the main spoke and the fixing plate rotate 90 degrees, the salient points and the grooves are tightly matched to generate resistance to offset the torsion generated by the auxiliary spoke to the fixing plate under the action of gravity, so that the semi-unfolding state is kept stable.

The main spoke is provided with a fixing hole and is used for being connected with a baby crib bag or a pet bag, and the magic tape penetrates through the fixing hole and is connected with the baby crib bag or the pet bag, so that the assembly and the disassembly and the cleaning are convenient.

The above description is only for the purpose of illustrating the preferred embodiments of the present invention and is not to be construed as limiting the present invention, and it will be understood by those skilled in the art that various changes and modifications may be made therein without departing from the spirit and scope of the invention.
