Description

A material-saving portable three-legged seat

technical field

The utility model relates to the technical field of household articles, in particular to a material-saving portable three-legged seat.

Background technique

Seats are an indispensable daily necessities in people's lives. The existing seats are large in size and need to occupy a certain indoor area in people's home life. They are not easy to carry when people go out to play, and they can be carried in cars The quantity is very limited, which is very inconvenient. Therefore, some portable foldable seats have appeared on the market, but the existing foldable seats are often not so light, and even, due to the addition of a complicated adjustment structure, the weight of the seat itself is reduced. There is no reduction, either it is bulky and inconvenient to carry, or it is portable but cumbersome to assemble.

Contents of the invention

The purpose of the utility model is to propose a material-saving portable three-legged seat in view of actual living conditions and the deficiencies of the prior art.

A material-saving portable three-legged chair proposed by the utility model includes a chair surface and chair feet. When the end of the chair foot away from the chair surface is rotated relative to the chair surface, the chair foot is folded and rotated away from the chair surface to form a supporting frame to support the chair surface.

Further, it also includes a backrest, and the backrest is provided with a folding portion for the backrest to be folded.

Further, it also includes a connecting piece arranged under the chair surface, and the chair feet are rotatably connected to the connecting piece.

Further, the connecting piece includes a connecting seat and an adjusting screw welded to the chair surface.

Further, the chair foot is provided with a bolt hole adapted to the adjusting screw.

Further, the chair legs are provided with retractable parts.

Further, a base is provided at the end of the chair foot away from the connecting piece.

Further, the chair surface is provided with multiple sets of through holes.

Further, the chair legs are made of plastic-metal composite material.

The utility model is a material-saving portable three-legged chair. The main body only includes the chair surface, the chair feet and the backrest, wherein the chair feet can rotate relative to the chair surface, and the backrest can be turned toward the chair surface at the folding part, so that the folding Finally, it can reach a very small volume, which is convenient for users to carry; on the other hand, the utility model adopts a tripod support frame, and the three groups of chair legs are respectively arranged at the trisection points of the chair surface, and the force is balanced. When the pressure is applied, the chair feet at three different positions have an inclination angle with the chair surface, which will generate horizontal thrust at the base, weakening the vertical pressure, and the overall structure is quite stable. At the same time, the chair feet are made of plastic-metal composite materials. It has both the excellent properties of plastic and metal, and it is rust-free, pollution-free, green manufacturing, environmentally friendly and material-saving, lightweight and practical, and the process is simplified, which greatly reduces the manufacturing cost. In addition, due to the simple structure, it also avoids the need for assembly. trouble.

Detailed ways

In order to more clearly illustrate the embodiments of the utility model and the technical solutions in the prior art, the specific implementation of the utility model will be described below with reference to the accompanying drawings. Obviously, the accompanying drawings in the following description are only some embodiments of the present utility model, and those skilled in the art can also obtain other accompanying drawings according to these drawings without creative work, and Get other implementations. In addition, the affiliation related to the orientation only indicates the relative positional relationship between the components, not the absolute positional relationship.

Please refer to Figure 1 and Figure 2. A material portable three-legged chair according to the embodiment of the utility model comprises a chair surface 1 and chair feet 2, the chair surface 1 is a round surface, and the chair feet 2 are rotatably connected to three equal parts of the outer edge of the chair surface 1 point, so that when the end of the chair foot 2 away from the chair surface 1 rotates relative to the chair surface 1, the chair foot 2 is folded and turns away from the chair surface 1 to form a support frame, facing the chair surface 1 for support.

The utility model adopts a tripod support frame, and three groups of chair feet 2 are respectively arranged at the trisection points of the chair surface 1, and the angular interval of each connection point is 120 degrees based on a circumference of 360 degrees, and each connection point reaches The distances between the centers of the circles are equal, and this mechanical structure utilizes the inclination angle formed by the chair feet 2 and the chair surface 1 to disperse the vertical pressure, and the overall structure is stable and reliable. The three sets of chair legs 2 can respectively rotate around the connecting points, and then fit the chair surface 1, so that the overall volume is compressed.

In this embodiment, a backrest 3 is also included, and the backrest 3 is provided with a folding portion 30 for the backrest 3 to be folded. In this way, when in use, it is folded up, and when not in use, it is also easy to fold, reducing the overall volume. , more portable.

The connecting piece 4 includes a connecting seat 40 welded to the chair surface and an adjusting screw 41. One end of the chair leg 2 is provided with a bolt hole for matching with the adjusting screw 41. By adjusting the adjusting screw 41, the chair leg 2 can be changed. working status.

The chair leg 2 is also provided with a retractable part, which is convenient for folding and effectively reduces the volume after being bundled.

The end of the chair leg 2 away from the connector is provided with a base 20, which is a rectangular block welded to the end of the base. By increasing the contact area with the support surface, the pressure is reduced, and it is very suitable for some outdoor areas where the ground soil is relatively loose. Scenes.

The seat surface 1 is provided with multiple groups of through holes, which is comfortable and breathable, and the weight of the seat is reduced as a whole, which is convenient for users to carry.

Chair foot 2 adopts plastic-metal composite material to make, and this composite material has the excellent performance of plastic and metal concurrently, and does not get rusty, has no pollution.
