Technical Field

[0001] The utility model belongs to the technical field of painting, and in particular relates to a drawing board. Background Art

[0002] On a technical level, painting is a process of adding color to a surface. The surface can be paper or cloth. The tools for adding color can be brushes, sponges, or strips of cloth. You can also use software to paint.

[0003] When art students go out for sketching and painting, they often need to carry a drawing board. However, the existing drawing board has a relatively simple structure and lacks a protective structure for the drawing board on which paper is laid. It also cannot meet the adjustment requirements for different painting angles. Based on this, the utility model application designs a drawing board. Utility Model Content

[0004] In order to solve the above problems existing in the prior art, the utility model provides a drawing board, which has the characteristics of protecting the drawing board and adjusting the drawing angle at the same time. In order to achieve the above purpose, the utility model provides the following technical solutions: a drawing board, including a backboard, hinged seats are installed on both sides of the outer surface of the backboard, a first clamping plate is hingedly installed inside the two hinged seats, a second clamping plate is slidably installed inside the two first clamping plates, two slide grooves are provided on the other side of the backboard, and a protective structure is slidably installed inside the two slide grooves; the protective structure includes two sliders, a clamping groove ring is installed inside the two sliders, a first cover plate is installed on the outer surface of the two sliders, fastening bolts are threadedly installed on both sides of the outer surface of the first cover plate, folding rods are threadedly installed on the outer surfaces of the two fastening bolts, a second cover plate is installed between the two folding rods, and a counter groove is provided on one side of the two second cover plates.

[0005] As a preferred technical solution for a drawing board of the utility model, two adjustable shoulder straps are installed on one side of the outer surface of the backboard, fixing structures are installed on both sides of the outer surface of the backboard, and a drawing board is installed on one side of the outer surface of the backboard.

[0006] As a preferred technical solution of a drawing board of the utility model, the two fixing structures include two fixing plates, and a mounting plate is installed between the two fixing plates.

[0007] As a preferred technical solution of the drawing board of the utility model, abutment plates are installed inside the two mounting plates, and springs are installed at one end of the two abutment plates.

[0008] As a preferred technical solution for a drawing board of the utility model, a limiting sleeve is installed at one end of the two springs, and the limiting sleeve passes through the abutment plate.

[0009] As a preferred technical solution of the drawing board of the utility model, a rotating plate is rotatably mounted on one end of the top of the limiting sleeve, and a connecting rod is installed inside the rotating plate.

[0010] As a preferred technical solution of the drawing board of the utility model, the connecting rod and the limiting sleeve are rotatably connected, and a clamping head is installed at one end of the bottom of the connecting rod, and two protrusions of the clamping head are adapted to the clamping groove ring.

[0011] Compared with the prior art, the beneficial effects of the utility model are:

[0012] 1. When the utility model is in use, through the protective structure, the hinge seat and the first card plate, when the device is carried out, the drawing board is covered by the first cover plate and the second cover plate to prevent it from being damaged by external factors. When it is necessary to draw, the slider is made to slide in the slide groove and slide to the bottom through the fixing structure. At this time, the fastening bolt is loosened, and the folding rod is turned to drive the second cover plate to fold counterclockwise to any angle. At the same time, the two first card plates on the inner side of the back plate are turned out from the hinge seat, and the two second card plates are pulled out of the first card plates to any length so that their bottoms are against the groove. At this time, the fastening bolt is tightened again to fix the folding rod and the second cover plate. At this time, one side of the second cover plate plane is placed horizontally on the ground. At this time, the drawing board has a drawing angle, thereby achieving the purpose of protecting the drawing board and adjusting the drawing angle at the same time;

[0013] 2. When the utility model is in use, through the protective structure and the fixed structure, in a normal state, the two protrusions of the clamping head are clamped in the clamping groove ring at the X-axis level. At this time, the spring cannot bounce open, resulting in the fixation of the slider and the mounting plate. When the protective structure needs to be pulled down, the rotating plate is rotated 90°. At this time, the connecting rod drives the clamping head to rotate 90° in the limit sleeve. At this time, the two protrusions of the clamping head are disengaged from the clamping groove ring. At this time, the spring releases force and bounces up, thereby separating the slider from the fixed plate. At this time, the protective structure can be slid in the slide groove, thereby achieving the purpose of fixation. BRIEF DESCRIPTION OF THE DRAWINGS

The two fixed structures 9 include two fixed plates 91, and a mounting plate 92 is installed between the two fixed plates 91. Abutment plates 93 are installed inside the two mounting plates 92, and springs 94 are installed at one end of the two abutment plates 93. A limiting sleeve 95 is installed at one end of the two springs 94, and the limiting sleeve 95 passes through the abutment plates 93. A rotating plate 96 is rotatably installed at the top end of the limiting sleeve 95, and a connecting rod 97 is installed inside the rotating plate 96.

[0024] Under normal conditions, the two protrusions of the clamping head 98 are clamped in the clamping groove ring 83 at the X-axis level. At this time, the spring 94 cannot bounce open, causing the slider 81 to be fixed to the mounting plate 92. When the protective structure 8 needs to be pulled down, the rotating plate 96 is rotated 90°. At this time, the connecting rod 97 drives the clamping head 98 to rotate 90° in the limiting sleeve 95.

[0025] Working principle and use process of the utility model: during the use of the utility model, first, when the device is in the outside world, the two protrusions of the clamping head 98 are clamped in the clamping groove ring 83 at the X-axis level. At this time, the spring 94 cannot bounce off, resulting in the slider 81 and the mounting plate 92 being fixed, so that the first cover plate 82 and the second cover plate 86 can protect the drawing board 6. When painting is needed, the rotating plate 96 is rotated 90°. At this time, the connecting rod 97 drives the clamping head 98 to rotate 90° in the limiting sleeve 95. At this time, the two protrusions of the clamping head 98 are disengaged from the clamping groove ring 83, and the spring 94 releases the force and bounces up, thereby Separate the slider 81 from the fixed plate 91, then slide the two sliders 81 to the bottom of the slide groove 7, loosen the fastening bolts 84 at the same time, and turn the folding rod 85 to drive the second cover plate 86 to fold counterclockwise to any angle. At the same time, flip out the two first clamps 4 on the inner side of the back plate 1 from the hinge seat 3, pull the two second clamps 5 out of the first clamps 4 to any length so that their bottoms are against the grooves 87, then tighten the fastening bolts 84 again to fix the folding rod 85 and the second cover plate 86, and then place one side of the plane of the second cover plate 86 horizontally on the ground, and the drawing board 6 has a drawing angle.
