Description

Technical Field

[0001] The utility model relates to the technical field of painting auxiliary tools, in particular to an easel with strong stability. Background Art

[0002] An easel is a support for placing a drawing board when painting. It mainly plays an auxiliary supporting role for the drawing board. When using an easel for painting, the drawing board is usually fixed on the easel, and then the easel is placed in a designated position. Then the painter holds the brush and paints on the drawing board. In order to facilitate the easel to be carried outdoors for use, most easels are currently made of wood to reduce the weight and cost of the easel.

[0003] In the current existing easel technology, a tripod support frame is usually used for support. The tripod support frame usually includes a main frame and a support frame. The support frame is used to support the main frame. The main frame includes a main rod. A drawing board support that can slide along the main rod is provided on the main rod. A first fixing plate is provided below the drawing board support. The first fixing plate is arranged on the front side of the main rod, and a second fixing plate is provided on the back side of the main rod. Both ends of the first fixing plate and the second fixing plate are connected by long bolts. This type of drawing board is easy to carry and has stable support, but the following problems still exist: 1. Due to the long length of the drawing board support, the drawing board support is connected to the main frame only through the main rod, that is, it is only connected to the main frame through the middle position of the drawing board support, and the two ends of the drawing board support are suspended. When the drawing board is placed on the drawing board support for use, it is easy for the drawing board support to shake in the left and right directions, which is not easy for users to use; 2. The drawing board support is easy to cause jamming during the up and down movement, and after long-term use, the first fixing plate and the second fixing plate will be worn, causing the drawing board support to loosen when sliding along the main rod, reducing the service life of the easel; 3. The first fixing plate and the second fixing plate are both fixed by long bolts, which are easy to cause cracks in the first fixing plate and the second fixing plate when moving up and down; 4. When the drawing board is placed on the drawing board support, since the drawing board support is only connected to the main rod, it cannot ensure that the drawing board support is in a horizontal position at all times, and therefore it cannot ensure that the drawing board is in a horizontal state. Utility Model Content

[0004] The utility model aims to provide an easel with strong stability. The easel will not shake left and right when in use. The easel has strong stability, is convenient for adjusting the position of the drawing board support, and can keep the drawing board in a horizontal position without tilting.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

At this time, the second fixing plate is stuck in the second slide and can slide up and down along the second slide. When the second fixing plate slides to the specified position, the other end of the drawing board support is fixed by tightening the second fastener.

[0017] By setting a level detection device on the side of the drawing board support away from the main frame, the user can intuitively judge whether the drawing board support is in a horizontal state according to the display of the level detection device. If the drawing board support is not in a horizontal state, the height of the drawing board support from the ground can be adjusted according to the level detection device to adjust the drawing board support to a horizontal state for easy use. By setting a clamping component on the third support rod, the clamping component can clamp the drawing board from the top to prevent the external drawing board from moving during use.
