Description

Technical Field

[0001] The utility model relates to the technical field of drawing stands, in particular to a combined drawing stand. Background Art

[0002] Drawing is drawing, which includes engineering drawing, design drawing, plane drawing, three-dimensional drawing, etc. It is widely used in daily production. Among them, hand-drawing is the most common way of drawing. Hand-drawing is an important professional compulsory course for students engaged in architecture, clothing display design, window design, home soft decoration design, space floral design, fine arts, gardening, environmental art, photography, industrial design, visual communication and other majors. In the process of drawing, a drawing stand is needed. The existing drawing stand consists of a bracket and a drawing board.

[0003] Patent CN219487030U proposes a combined drawing device, which places the entire device on a plane, and then supports the drawing board by snapping one end of the support plate into the interior of the positioning grooves at different positions. Moreover, when the support plate is inserted into the interior of the positioning grooves at different positions, the inclination angle of the drawing board will change accordingly, thereby achieving the purpose of being able to flexibly adjust the inclination angle of the drawing board.

[0004] The above scheme adjusts the angle of the drawing board by adjusting the positioning groove and the support plate to meet the needs of different drawing angles. However, in this technical scheme, since the plane of the positioning groove and the drawing board part are an integrated structure, they cannot be disassembled, and thus it is inconvenient to store and carry them separately. When drawing requires height requirements, it is necessary to use other structures such as a desktop to raise the height of the device, which affects the use of the device. Utility Model Content

The utility model has a novel structure. The placement plate is installed with the base through plug-in columns and connecting rods. The placement plate can be rotated to a certain angle through the separation of the distance between the rear plate and the front plate. The base can be raised to a certain height through the lifting components on both sides, thereby meeting the user's requirements for drawing angles and heights. It is more convenient to use and it is also more convenient to carry the separate storage box.

[0006] In order to achieve the above-mentioned purpose, the utility model is implemented through the following technical scheme: a combined drawing stand, including a base, the base including a front plate and a rear plate, two pulleys are symmetrically installed on the bottom of the rear plate, and the bottom of the pulley is in the same straight line as the bottom of the front plate, a placement plate is installed on the top of the front plate and the rear plate, and clamping frames are fixed on both sides of the front of the placement plate, lifting components are arranged on both sides of the front plate and the rear plate, plug posts are fixed on both sides of the top of the front plate, and rotating shaft seats are symmetrically installed on both sides of the bottom of the placement plate, and plug holes are opened on the surface of the rotating shaft seat, and the plug posts can be plugged into the inside of the plug holes.

[0007] Furthermore, a screw barrel is symmetrically fixed on the top of the rear plate, two connecting rods are symmetrically provided on the back of the placement plate, and studs are fixed on the bottom of the connecting rods, and the studs are engaged and inserted into the screw barrel.

[0008] Furthermore, two slide grooves are symmetrically provided on the back side of the placement plate, and a slide plate is slidably installed on the surface of the slide groove, and the connecting rod is rotatably installed on the outer surface of the slide plate through a rotating shaft.
