[0021] like Figure 1-Figure 4 As shown, the utility model provides a technical solution: a foldable drawing board for architectural design, comprising a drawing board 1, wherein the drawing board 1 is provided with a folding mechanism 2 for folding and storage, and the folding mechanism 2 is provided with a protective mechanism 3.

[0022] The folding mechanism 2 comprises: a palm rest 201, an anti-skid protective layer 202, a stopper 203, a buckle 204, a slider 205, a reset spring 206, a limit spring 207, and a push button 208. The side wall of the palm rest 201 is hinged to the side wall of the drawing board 1. The palm rest 201 is arranged on both sides of the drawing board 1. The bottom of the palm rest 201 is fixedly connected to the top of the anti-skid protective layer 202. The side wall of the palm rest 201 is fixedly connected to the inner wall of the stopper 203. The outer wall of the stopper 203 is in contact with the inner wall of the palm rest 201. 01 is slidably connected with the side wall of the buckle 204; the buckle 204, the inner wall of the buckle 204 is hinged with the outer wall of the slider 205, the outer wall of the slider 205 is fixedly connected with the bottom of the reset spring 206, the top of the reset spring 206 is fixedly connected with the bottom of the buckle 204, the inner wall of the slider 205 is fixedly connected with one end of the limit spring 207, the end of the limit spring 207 away from the slider 205 is fixedly connected with the palm rest 201, and the top of the slider 205 is fixedly connected with the bottom of the push button 208. The bottom of the drawing board 1 is fixedly connected with the inner wall of the protective frame 301, the inner wall of the protective frame 301 is hinged with the top of the support frame 302, and the side wall of the support frame 302 is fitted with the inner wall of the protective frame 301. The limiter 203 is set at the top of the palm rest 201 on the left side of the drawing board 1, and the buckle 204 is set at the top of the palm rest 201 on the right side of the drawing board 1. There are two sets of protection mechanisms 3, which are symmetrically arranged at the bottom of the drawing board 1 with the drawing board 1 as the center line. The flip direction of the palm rest 201 is limited to upward, and the maximum flip angle of the palm rest 201 is 180°. The maximum flip angle of the support frame 302 and the protection frame 301 is 130°.

[0023] Working principle: the palm rests 201 on both sides of the drawing board 1 can be flipped inwards and folded for recycling. During the recycling process, the limiter 203 on the surface of the left palm rest 201 will squeeze the buckle 204 to make it flip inwards. After being squeezed to the extreme position, the buckle 204 will pop out and reset under the drive of the reset spring 206, so that the limiter 203 and the buckle 204 are in a fixed state. When it is necessary to release the fixation, the push button 208 is moved to move the slider 205 inwards, so that the buckle 204 releases the limit on the limiter 203. This mechanism can keep the drawing board 1 stable in the non-use folded state, prevent the drawing board 1 from opening abnormally to occupy storage space and damage internal drawings, and improve the overall stability.

[0024] A protective frame 301 and a support frame 302 are provided on the back of the drawing board 1 for auxiliary support. The protective frame 301 and the support frame 302 can be folded and stored with each other and can be unfolded to form a triangular structure with the drawing board 1 as a bottom support to reduce wear efficiency.
