Description

A multifunctional and dual-purpose elevating easel with graphic design

technical field

The utility model relates to the field of graphic design, in particular to a multifunctional and dual-purpose elevating easel for graphic design.

Background technique

Easel is often used in the process of graphic design. Easel can help graphic designers to better express information such as product shape and properties. The existing easels on the market have a single structure, and there are many problems such as lifting and lowering of the drawing board and inconvenient use. Therefore, there is an urgent need for a novel easel that can flexibly adjust the lifting height and has a more practical structure.

Utility model content

The utility model proposes a new technical solution for the above-mentioned technical problems: a multifunctional and dual-purpose lifting easel with a planar design. A lifting mechanism is provided, and the lifting mechanism includes a base, two scissor-type support arms, a limit sleeve, a handle, a threaded slider, and a lead screw. The base is fixed on the table leg, and the scissor-type One end of the four support arms of the support arm is connected to the threaded slider by a pin shaft, the other ends of two of the support arms are connected to the base by a pin shaft, and the other ends of the other two support arms are connected by a pin shaft Connected to the support block, the limit sleeve is sleeved on the lead screw, the threaded slider is arranged on both sides of the limit sleeve, a crank is provided at one end of the lead screw, and a handle is connected to the upper end of the support block. drawing board.

An angle adjustment block is arranged between the drawing board and the supporting block.

There are two supporting blocks, and a rigid spring is arranged between the two supporting blocks.

There are four lifting mechanisms, and two lifting mechanisms are arranged symmetrically on each table foot.

Beneficial effects of the utility model: the utility model can be used not only as a writing desk but also as a drawing board for graphic design, which improves the practicability of the scheme. The height and angle of the working plate are adjusted by the combination of the lead screw and the threaded slider. The mechanism is reliable and stable in performance.

Detailed ways

Below in conjunction with accompanying drawing 1 and 2 examples the utility model is described in further detail.

A multi-functional and dual-purpose elevating easel with a planar design. The multi-functional and dual-purpose elevating easel includes two table legs 1. It is characterized in that a lifting mechanism is respectively arranged on the two table legs 1. The elevating mechanism includes a base 2. Two scissor support arms 3, limit sleeve 4, crank handle 5, threaded slider 6, screw 7, the base 2 is fixed on the table leg 1, the scissor support arm 3 One end of the four support arms is connected to the threaded slider 6 by pin shafts, the other ends of the two support arms are connected to the base 2 by pin shafts, and the other ends of the other two support arms are connected by pin shafts On the support block 8, the limit sleeve 4 is sleeved on the lead screw 7, and the threaded slider 6 is arranged on both sides of the limit sleeve 4, and one end of the lead screw 7 is provided with a crank handle 5, where The upper end of the support block 8 is connected with a drawing board 9 .

An angle adjustment block 10 is provided between the drawing board 9 and the support block 8 .

There are two supporting blocks 8, and a rigid spring 11 is arranged between the two supporting blocks 8.

There are four lifting mechanisms, and two lifting mechanisms are arranged symmetrically on each table foot 1 .

The working principle is as follows: rotate the crank handle 5, and the crank handle 5 drives the screw 7 to rotate. When the screw 7 is driven, the two threaded sliders 6 move toward or away from each other, and the two sides of the threaded slider 6 are connected to four support arms. The motion of block 6, scissors type support arm 3 does stretching action, has therefore realized the lifting of work plate. When the device is used as a writing desk or a desk, the four lifting mechanisms have the same telescopic height, and the working board 8 is level; when the device is used as a drawing board, the rear two lifting mechanisms can be raised and the front two lifting mechanisms can be lowered. The angle of the drawing board 9 is adjusted to be used as a drawing board.

The foregoing has described the specific implementation of the utility model with reference to accompanying drawings 1 and 2, those skilled in the art should understand that the utility model is not limited to the embodiment described above, and can be made without departing from the spirit of the utility model Various modifications should also be included within the scope of the present utility model. The scope of the present invention should be defined by the appended claims and their equivalents.
