It is to be understood that the described embodiments are merely exemplary of the invention, and not restrictive of the full scope of the invention. All other embodiments, which can be derived by a person skilled in the art from the examples given herein without any inventive step, are within the scope of the present invention.

As shown in fig. 1 and 2, the invention provides a multifunctional angle-adjustable liftable drawing table, which comprises a table top 1, a table frame 2, table legs 3, a U-shaped support 4, a blocking base 5 and an adjusting component 9, wherein the U-shaped support 4 is rotatably arranged on the table top 1; and two chutes 11 are longitudinally and parallelly arranged on the desktop 1, the blocking base 5 is slidably arranged in the chutes 11, and the blocking base 5 can be limited and locked at any distance from the desktop 1 through the adjusting component 9.

Two spouts 11 have been seted up longitudinally in parallel on desktop 1, separate and keep off base 5 slidable and set up in spout 11, and can realize separating through adjusting part 9 and keep off base 5 in the arbitrary far and near spacing locking of desktop 1, U-shaped supports 4 and separates and keep off base 5 fixed drawing board that cooperatees, the drawing board can optionally be fixed in and be close to user or keep away from user's position, adjust some with the drawing board during sketch, adjust some far away with the drawing board when drawing gouache, accord with ergonomic design, the painter comfort level improves after the adjustment gesture, help vast teenagers' healthy development.

The multifunctional angle-adjustable lifting painting table comprises a culture course mode and a professional painting course mode, and when the culture course mode is adopted, the U-shaped supports 4 and the blocking bases 5 are in a storage state, so that normal lessons are not influenced; during the specialty drawing mode, only need the angle that the U-shaped was supported 4 of adaptability regulation and the position that separates fender base 5, can fix the drawing board and draw, satisfy the drawing board of various sizes and use, little to four-split drawing board is big to opening the drawing board of even bigger size entirely.

As an alternative embodiment, as shown in fig. 3 and 4, the adjusting assembly 9 includes a long rack 91 and a short rack 92, the long rack 91 is fixed to the table frame 2 and is disposed corresponding to the sliding chute 11, the blocking base 5 is fixedly connected to the short rack 92 through the sliding chute 11, and the engaging teeth of the short rack 92 can be fittingly engaged in any tooth socket of the long rack 91 to achieve locking of the blocking base 5.

The mode that long rack 91 and short rack 92 mesh mutually is adopted, and the tooth of short rack 92 meshes with the tooth's socket of difference on the long rack 91 so that realize keeping off the stop of base 5 optional position, and convenient operation just can set for the tooth width according to the adjustment demand, wants the fine setting just a little, wants the coarse setting just a little.

As an alternative embodiment, the end of the baffle base 5 is extended to form a short rack 92.

The blocking base 5 and the short rack 92 are integrally formed, so that the strength and the reliability are high.

In an alternative embodiment, a position of the blocking base 5 near the short rack 92 is provided with a limiting groove 921, the table frame 2 is provided with a guide post 93, and the guide post 93 is disposed in the limiting groove 921.

When the distance between the drawing board and the ground is required to be adjusted, the baffle base 5 is lifted, the short rack 92 and the long rack 91 are separated from each other, the position where interference is not generated is the lower end face of the limiting groove 921, at the moment, the hand is loosened when the baffle base 5 is pushed to the proper position along the sliding groove 11, the baffle base 5 moves downwards under the action of gravity, the short rack 92 is meshed with the long rack 91 again, and the baffle base 5 is limited and locked.

As an alternative embodiment, the two ends of the U-shaped support 4 may be pivotally disposed at the distal end of the table top 1 via a hinge mechanism.

The U-shaped support 4 can be rotatably arranged at the far end of the desktop 1, can rotate a certain angle according to the distance and angle requirements, and is matched with the blocking base 5 to fix the drawing board.

As an alternative embodiment, the hinge mechanism is an angle adjuster 10 as shown in fig. 5-7, the angle adjuster 10 includes a first retaining piece 101, a second retaining piece 102, a locking piece, a fixing piece 103 and a connecting piece 104, the angle adjuster 10 is fixedly connected with the table frame 2 through the fixing piece 103, the second retaining piece 102 is fixedly connected with the U-shaped support 4 through the connecting piece 104, and the first retaining piece 101 and the second retaining piece 102 are in rotatable friction fit.

The first brake block 101 and the second brake block 102 are in rotatable friction fit, so that the U-shaped support 4 can be stopped arbitrarily, and the locking piece can improve the connection stability between the first brake block 101 and the second brake block 102.

Knurling is performed on the joint surfaces of the first brake plate 101 and the second brake plate 102 to increase the frictional force therebetween.

As an alternative embodiment, the hinge mechanism further includes a handle 107, the locking member includes a locking screw 105 and a nut 106, one end of the locking screw 105 is fixed to the handle 107, and the other end of the locking screw 105 is threaded with the nut 106 through the second catch 102 and the first catch 101 in turn.

Raising U-shaped support 4 rotates against the friction between second brake plate 102 and first brake plate 101. Firstly, turning the handle 107 in the counterclockwise direction, wherein the pressure exerted on the first brake piece 101 and the second brake piece 102 by the locking screw 105 is reduced, and the U-shaped support 4 can be turned; after the required angle is adjusted, the handle 107 is rotated clockwise, and at this time, the pressure exerted on the first brake pad 101 and the second brake pad 102 by the locking screw 105 is increased, and the friction force acting between the two brake pads is increased to achieve the purpose of rotation stopping and fixing.

As an alternative embodiment, the blocking base 5 includes a U-shaped base body 51 and a picture plate holder 52 provided on the base body.
