The utility model relates to a portable art easel.

Please refer to 1 for details. FIG. 1 is a schematic diagram of the overall structure of the present invention.

This portable art easel includes:

Support backplane 1;

the top L-board 2 fixed on the top of the support backboard 1;

The bottom L plate 3 fixed on the bottom of the support back plate 1;

Rotate the legs 4 connected to both sides of the bottom L-plate 3 .

A handle 21 is mounted on the top of the top L-board 2 , and a universal pulley 31 is mounted on the bottom of the bottom L-board 3 . Here, the structure of the handle 21 is similar to the structure of the existing luggage, which belongs to the relatively mature prior art, and will not be repeated in this application.

For details, please refer to FIG. 2, which is a back side view of the overall structure of the present invention;

A side connecting plate 32 is fixed on one side of the bottom L plate 3, and a top rotating plate 41 is fixed on the top of the supporting leg 4. The side connecting plate 32 and the top rotating plate 41 are rotatably connected by a rotating shaft. A plurality of first limiting grooves are evenly opened on the side of the side connecting plate 32 and centered on the rotating shaft, and the supporting legs 4 are also provided with first assembling grooves corresponding to the first limiting grooves; this The portable art easel also includes a first insertion rod 5, and the first insertion rod 5 penetrates through the first assembly groove and extends into the first limiting groove, so as to realize the connection between the supporting leg 4 and the bottom L plate 3. The limit and adjustment of the rotation between.

The outrigger 4 includes an outer rod 42 and an inner sliding rod 43, and one side of the inner sliding rod 43 is provided with a plurality of second limit grooves at the same height, and one side of the outer rod 42 is provided with the same height. The second assembly slot corresponding to the second limit slot, the portable art easel further includes a second insertion rod 6, and the second insertion rod 6 penetrates through the second assembly slot and extends into the second limit. Inside the slot, the length of the outriggers 4 can be adjusted and fixed, thereby adjusting the height of the portable art easel.

Please refer to Figure 1 for details:

A rectangular groove 4A is defined on the front and back of the bottom of the outrigger 4 , and an anti-roll bar 44 is rotatably connected to the bottom end of the rectangular groove 4A.

Specifically, one end of the anti-roll bar 44 is rotatably connected to the inner bottom end of the rectangular groove 4A through a rotating shaft, and two third limiting grooves are also opened at the bottom of the supporting leg 4 and centered on the rotating shaft , the connection line between the two limit slots and the rotating shaft is at an angle of 90 degrees, and a third assembly slot is also opened on one side of the anti-roll bar 44. The portable art easel also includes a third insertion rod 7, so The third insertion rod 7 penetrates through the third assembly groove and extends into the third limiting groove to achieve a ninety-degree fixation to the anti-roll bar 44 to ensure that it shrinks inside the rectangular groove 4A. Or fixed vertically on the front and back of the legs 4 .

With the arrangement of the anti-roll bar 44, it can be ensured that the outrigger 4 will not fall over when in use.

In addition, in order to further ensure its reliability, the anti-roll bar 44 is a retractable structure, and the specific structure can refer to the outer rod 42 and the inner sliding rod 43 of the outrigger 4 , which will not be repeated here.

In addition, in order to further realize the storage of articles, a storage box is also installed on the back of the support backplane 1 .

In addition, in order to ensure that the first insertion rod 5 does not fall off in the first limiting groove, the second insertion rod 6 does not fall off in the second limiting groove, and the third insertion rod 7 does not fall off in the third limiting groove fall off, permanent magnets can be arranged in the first limit slot, the second limit slot and the third limit slot, and the first insertion rod 5, the second insertion rod 6 and the third insertion rod 7 are made of metal material , so that it is connected by magnetic attraction.

Please also refer to FIG. 3: FIG. 3 is a schematic diagram of the folding of the portable art easel.

It can be seen that when folding, the anti-roll bar 44 is first retracted inside the rectangular groove 4A, then the outrigger 4 is shortened to the shortest, and then the outrigger 4 is rotated to the top, and the first insertion rod 5 and the second insertion rod are respectively passed through. 6 and the third insertion rod 7 are limited and fixed. Then, by pulling the handle 21 by hand, under the action of the universal pulley 31, labor-saving movement can be realized.
