Description

A four-fold folding table

technical field

The utility model relates to the field of tourist supplies, in particular to a folding table.

Background technique

With the development of society, people's material living standards continue to improve, and there are more and more people with cars. It has become fashionable to travel outdoors by car. Folding tables are used in outdoor picnics, tourism, camping and other activities. Folding, small and compact structure, good for storage, so the market demand for folding tables is increasing year by year. In the patent ZL201210006748, a folding table is disclosed. This folding table can only realize the rotation and folding of the table legs, and the two table legs on the left and right sides are supported by the same metal rod, and are limited by the limit mechanism. The rotation range of the two table legs on the same side, and the desktop cannot be folded, because the folding table required for outdoor activities is usually placed in the trunk of the car, and the trunk of the car not only has limited space, but also has a large impact on the length of the contents. There are restrictions on width and height, and people hope that the width of the desktop can be folded into a smaller size, which is more convenient to carry.

In order to solve the above problems, the applicant has developed a folding table composed of four rectangular table top boards. Not only can each table leg be folded separately, but also the width of the table top can be folded into a quarter size. The compressive strength can be greatly improved.

Utility model content

The purpose of this utility model is to provide a four-fold folding table, each table leg can independently realize the rotation vertical limit, after folding, it can be horizontally attached to the back of the table top, the structure is simple, the use is simple and reliable, and the folded table top The width is only a quarter of the width of the unfolded desktop, which is more convenient to use and carry. If an anti-compression device is provided on the back of the desktop, the compression resistance of the desktop can be greatly improved.

The technical scheme that the utility model takes is as follows:

A four-fold folding table, including a table top and flip table legs connected under the table top, is characterized in that: the table top includes a first plate, a second plate, a third plate, a fourth plate, an outer hinge and a middle hinge page, wherein the first plate and the second plate are connected as a whole through an outer hinge, and the third plate and the fourth plate are also connected as a whole through another outer hinge, and the second plate and the third plate are connected through The middle hinges are connected; the two ends of the first plate and the fourth plate are respectively equipped with turning table legs, and the turning table legs include table legs, folding stays, rotating stays and rotating bases, and the upper ends of the table legs are rotated The base is fixed on the first plate or the fourth plate, and the table legs and the rotating base are connected by turning pins, the lower end of the rotating strut is twisted to the table legs, the upper end of the rotating strut is twisted to the right-angle fixing seat, and the right-angle fixing seat It is fixed on the first plate or the fourth plate, the upper end of the folding strut is hinged on the first plate or the fourth plate, the lower end of the folding strut is hinged with the table legs, and the eccentric height of the middle hinge is greater than that of the outer edge Hinge eccentric height.

At this time, the desktop width of the folding table is only 1/4 of the total width, and the width of the folding table is minimized.

The unfolding method of this folding table is as follows: the combination of the first plate and the second plate and the combination of the third plate and the fourth plate are opened through the middle hinge, and then the first plate and the second plate are closed through the outer edge. The pages are opened, and the third plate and the fourth plate are also opened through the outer hinges, and finally each table leg is straightened toward the outside of the table top, and finally the table top is placed upwards for use.

To improve the anti-compression capacity of the desktop in the above scheme, an anti-compression device should be added on the back of the desktop. The anti-compression device includes a rotating base, a rotating anti-compression bar and a limit base. The limit base is fixed on the back of the fourth plate, the rotating base and the limit base are on the same straight line, one end of the rotating anti-compression rod is hinged to the rotating base, and the other end of the rotating anti-compression rod is inserted into the limit base in the working state. In the limit mouth, and hold four boards.

Further, a group of anti-compression devices are provided on the back of the desktop. In the working state, the rotating anti-compression rod in the anti-compression device has an included angle with the length direction of the first plate. The sheet or the fourth sheet is parallel.

Furthermore, the anti-compression bar is rotated to coincide with the diagonal line of the desktop in the working state.

Furthermore, the anti-compression bar is rotated to be perpendicular to the first plate in the working state.

Further, two sets of anti-compression devices are provided on the back of the desktop, and the two groups of anti-compression devices are arranged in parallel and at intervals, and the installation directions are opposite. , and rotate the anti-compression bar to be parallel to the first plate in the folded state.

Further, the widths of the first board, the second board, the third board and the fourth board are the same.

Since the desktop is designed to be hinged by four boards, the four-fold folding of the desktop is realized, and the width of the folded desktop is reduced. Each turning table leg includes a table leg, a folding strut, a rotating strut and a rotating base, each turning leg can be folded independently, and an anti-compression device is added on the back of the desktop, and all the plates that make up the desktop are rotated. Supported by anti-compression rods, the anti-compression ability of the desktop can be greatly improved. The utility model has ingenious structure, convenient retraction and expansion, and strong practicability.
