Detailed Description

The following description of the embodiments of the present utility model will be made clearly and completely with reference to the accompanying drawings, in which it is apparent that the embodiments described are only some embodiments of the present utility model, but not all embodiments. All other embodiments, which can be made by those skilled in the art based on the embodiments of the utility model without making any inventive effort, are intended to be within the scope of the utility model.

In the description of the present utility model, it should be noted that the directions or positional relationships indicated by the terms "upper", "lower", "inner", "outer", "front", "rear", "both ends", "one end", "the other end", etc. are based on the directions or positional relationships shown in the drawings, are merely for convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the devices or elements referred to must have a specific direction, be configured and operated in the specific direction, and thus should not be construed as limiting the present utility model. Furthermore, the terms "first," "second," and the like, are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.

In the description of the present utility model, unless explicitly stated or limited otherwise, the terms "mounted," "configured to," "connected," and the like are to be construed broadly as, for example, "connected" may be fixedly connected, may be detachably connected, or integrally connected, may be mechanically connected or electrically connected, may be directly connected or indirectly connected through an intermediate medium, and may be communication between two elements. The specific meaning of the above terms in the present utility model will be understood in specific cases by those of ordinary skill in the art.

Referring to fig. 1, the novel folding seat of the present utility model comprises two major parts, namely a back plate sheet 1 and a seat plate sheet 2.

As shown in fig. 3, the back plate 1 has two back plate curved beams 3, the upper half of the back plate curved beams 3 forming a rest surface 7, the rest surface 7 being made of a number of cross beams protruding from the curved beams. The lower half of the back plate curved beam 3 forms the seat front leg.

As shown in fig. 4, the seat plate 2 has two seat plate curved beams 4, and the upper half of the seat plate curved beam 4 supports a seat surface, and the seat surface 8 is also made of a plurality of cross beams protruding from the curved beam. The lower half of the seat pan curved beam 4 forms the seat rear leg.

Two crosspieces are fixedly connected to the back plate curved beam 3 in the middle of the back plate sheet 1, and are respectively connected to the front and the back of the back plate curved beam, wherein the position of the front crosspiece 5 is lower than that of the back crosspiece 6, the middle space between the front crosspiece 5 and the back crosspiece 6 is enough to be inserted into the seat plate curved beam 4, the curvature of the seat plate curved beam 4 is the same as that of the back plate curved beam 3, and thus the seat plate curved beam 3 and the back plate curved beam 4 can be overlapped when being folded.

When unfolding, as shown in fig. 1, the seat plate curved beam 4 is intersected with the lower half part of the back plate curved beam 3, the chair leg part of the seat plate curved beam 4 is clamped between the front crosspiece 5 and the back crosspiece 6, the seat plate curved beam 4 and the back crosspiece 6 are firmly combined by means of gravity through leverage, the gravity of a person sitting on the seat surface can further strengthen the interaction between the seat plate curved beam and the back crosspiece, so that the combination is firmer, and the problem that the combined part of the existing folding seat breaks away from a scatter frame under the gravity is avoided.

Referring again to fig. 2, the folded state is shown. When folding, the seat plate curved beam 4 is inserted between the front crosspiece 5 and the rear crosspiece 6, and the back plate curved beam 3 is covered from the outer side of the back plate curved beam 3, and the beam protruding parts of the leaning surface 7 and the seat surface 8 are mutually intersected, so that the back plate curved beam 3, the seat plate curved beam 4, the front crosspiece, the rear crosspiece and the leaning surface seat surface are mutually clamped, a relatively firm sheet structure is formed, and the storage is more convenient.

As described above, the detachable seat provided by the utility model has the advantages that the chair legs are mutually connected by the structure of the lever principle, the seat surface and the leaning surface are fixedly connected to the chair legs by the screw fasteners, the chair legs play a supporting role by the lever principle, the angle of the seat can be adjusted by adjusting the two supporting bars on the chair legs, the part of the chair leg where the seat plate is positioned is extracted and inserted into the chair leg where the back plate is positioned, and the interaction stress is increased, so that the structure is stable. The two parts of the seat are arc-shaped, which accords with human engineering and can not be tired after sitting for a long time. The detachable seat is simple in structure, convenient to carry and easy to use and is not easy to damage.

The present utility model is not described in detail in the present application, and is well known to those skilled in the art.

It is finally intended that the foregoing detailed description be regarded as illustrative rather than limiting, and that it be understood that it is understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the utility model as defined by the appended claims.
