DETAILED DESCRIPTION

[0011] The present invention is further described in detail below in conjunction with the accompanying drawings and specific implementations.

[0012] A portable easel comprises an easel T-shaped keel 1, a telescopic tripod 2, a drawing board limiting support plate 3, and a telescopic upper limit frame 4. The telescopic upper limit frame 4 is connected to the easel T-shaped keel 1, and the telescopic upper limit frame 4 can be adjusted up and down on the top side of the easel T-shaped keel 1. The telescopic tripod 2 is provided with three groups, and the top ends of the three groups of telescopic tripods 2 are respectively connected to the two sides and the rear side of the easel T-shaped keel 1, and the three groups of telescopic tripods 2 can be adjusted in length. The drawing board limiting support plate 3 is connected to the front side of one group of telescopic tripods 2, and the drawing board limiting support plate 3 can be connected to the front side of an adjacent telescopic tripod 2.

[0013] The top side of the easel T-shaped keel 1 is provided with a limit rod insertion hole 5 which is transparent from top to bottom. The front side of the easel T-shaped keel 1 is provided with a limit fixing bolt 6, and the rear end of the limit fixing bolt 6 is inserted into the limit rod insertion hole 5. The telescopic upper limit frame 4 is composed of a drawing board fixing cap 7 and a limit rod 8. The drawing board fixing cap 7 is fixed to the top end of the limit rod 8, and the limit rod 8 is inserted into the limit rod insertion hole 5. The front side surface of the limit rod 8 is provided with a fixing groove 9, and the rear end of the limit fixing bolt 6 is in contact with the fixing groove 9 on the limit rod 8.

[0014] The telescopic tripod 2 is composed of multiple groups of telescopic joints 10, which are arranged in upper and lower sockets. The side of the telescopic joint 10 is provided with a fixing groove 9, and the side end of the telescopic joint 10 is provided with a telescopic fixing bolt 11. The side end of the telescopic fixing bolt 11 contacts the fixing groove 9 on the side of the telescopic joint 10. The two sides of the uppermost telescopic joint 10 are provided with connecting shafts 12, and the connecting shafts 12 are connected to the T-shaped keel 1 of the easel. A long slide groove 13 is provided at the center of the drawing board limiting support plate 3, and a fixed slide protrusion 14 and a sliding slide protrusion 15 are provided in the long slide groove 13. The fixed slide protrusion 14 passes through the long slide groove 13 and is fixed to the telescopic tripod 2 on one side. The sliding slide protrusion 15 passes through the long slide groove 13 and can be connected to the telescopic tripod 2 on the other side. The fixed slide protrusion 14 and the sliding slide protrusion 15 can both slide in the long slide groove 13.

[0015] Working principle of the present invention: This structure can be divided into two processes when in use: folding and unfolding. When folding, the lower telescopic joint 10 is stored in the upper telescopic joint 10, and the corresponding telescopic fixing bolts 11 are tightly fixed to the outside of the corresponding telescopic joint 10. In addition, the drawing board limit support plate 3 can be tightly attached to the outside of the telescopic tripod 2 and set in the same direction as the telescopic tripod 2. The telescopic upper limit frame 4 on the top side can be moved to the bottom, so that the top of the telescopic upper limit frame 4 is tightly attached to the upper side of the easel T-shaped keel 1, and then the telescopic upper limit frame 4 is fixed by the limit fixing bolts 6. After folding, the volume is small and convenient to carry. When unfolding, the telescopic joints 10 in the telescopic tripod 2 can be pulled out to the corresponding length respectively, and rotated at a small angle with the connecting shaft 12 as the axis, so that the three telescopic tripods 2 provide stable support. After the length is fixed, it is fixed by the telescopic fixing bolt 11. After the relative height is determined, the drawing board limit support plate 3 can be rotated with the fixed sliding protrusion 14 as the axis. When it is rotated to an intersection with the telescopic tripod 2 on the other side, it is fixed to the telescopic tripod 2 by the sliding protrusion 15. When a drawing board is to be fixed, the telescopic upper limit frame 4 can be pulled out, and then the drawing board fixing cap 7 can be used to fix the drawing board between the drawing board limit support plate 3 and the drawing board fixing cap 7.

[0016] The above is a preferred embodiment of the present invention. For ordinary technicians in this field, according to the teachings of the present invention, without departing from the principles and spirit of the present invention, changes, modifications, substitutions and variations made to the implementation methods are still within the scope of protection of the present invention.
