A retractable tubular portable bench, comprising a nested square tube assembly, an elastic clip, and a stool surface assembly. The square tube assembly includes a number of square tubes connected sequentially through elastic clips. The square tube is provided with a hollow channel, and the elastic clip Including arc-shaped shrapnel and circular protruding head, the circular protruding head is set at the end of the arc-shaped shrapnel, the arc-shaped shrapnel is set in the hollow channel of the square tube, and the square tube is provided with several positioning holes for the circular protruding head to pass through , the stool surface assembly is arranged on the top of the square tube assembly, the stool surface assembly includes a first leaf plate, a second leaf plate, a steel wire, a rotating shaft, the first leaf plate is rotatably connected to the end of the square tube, and the second leaf plate is rotatably connected to The rotating shaft is movably connected in the hollow channel of the square tube. The square tube is provided with a slot for positioning the second leaf plate. One end of the steel wire is connected to the end of the first leaf plate, and the other end of the steel wire is connected to the second leaf plate. The end of the leaf panel.

Further, the steel wire adopts two or more steel wires with a diameter of more than 1 mm arranged side by side.

Further, the bottom of the square tube assembly is provided with a support assembly, and the structure of the support assembly is the same as that of the stool surface assembly.

Further, it also includes a foldable cushion. The foldable cushion includes a cloth cover, Velcro, and a zipper. The two sides of the cloth cover are respectively provided with zippers, and the ends of the cloth cover are respectively provided with male or female Velcro stickers.

The beneficial effects of the utility model are: the shrinkable tubular portable bench is further compressed in volume and is easy to carry; it shrinks quickly and is convenient to use; the stool surface is a concave surface, making sitting more comfortable.

Detailed ways

Preferred embodiments of the present utility model will be described in detail below in conjunction with the accompanying drawings.

Example

A retractable tubular portable bench, comprising a nested square tube assembly 1, an elastic clip 4, and a stool surface assembly 2, as shown in Figures 1 and 2, the square tube assembly 1 includes several square tubes connected by elastic clips 4 in turn. Tube, square tube is provided with hollow channel, and elastic clip 4 comprises arc-shaped shrapnel 41 and circular protruding head 42, and circular protruding head 42 is arranged on the end of arc-shaped shrapnel 41, as Fig. 3, and arc-shaped shrapnel 41 is arranged on In the hollow channel of the square tube, the square tube is provided with some positioning holes for the circular protrusion 42 to pass through, and the stool surface assembly 2 is arranged on the top of the square pipe assembly 1, and the stool surface assembly 2 includes a first leaf plate 21, a second Leaf plate 22, steel wire 23, rotating shaft, as shown in Figure 4, the first leaf plate 21 is rotatably connected to the end of the square pipe, the second leaf plate 22 is rotatably connected to the rotating shaft, and the rotating shaft is movably connected in the hollow channel of the square pipe, The square tube is provided with a slot for positioning the second leaf plate 22 , one end of the steel wire 23 is connected to the end of the first leaf plate 21 , and the other end of the steel wire 23 is connected to the end of the second leaf plate 22 . The steel wire 23 adopts more than two steel wires 23 with a diameter of more than 1 mm arranged side by side.

The nested square tube assembly 1 uses three-level nested square tubes as the stool body. In the first and third level square tubes, the first leaf panel 21 and the second leaf panel 22 can be opened, and the second leaf panel 22 can rotate around the rotation axis. When the second leaf plate 22 rotates close to 90 degrees, it will be restrained by the steel wire 23 and put in place in the slot. The second leaf plate 22 cannot continue to rotate downwards, thereby forming the stool surface and support noodle.
