Specific embodiments

[0030] As Figures 1-5 shown, the present utility model provides a construction drawing drawing board for construction sites, including a drawing flat plate 100. A protection component 200 is arranged outside the drawing flat plate 100. The protection component 200 includes a protective shell 201, a fastening block 203 and a spring 204. The protective shell 201 is arranged outside the drawing flat plate 100. The fastening block 203 is arranged at the four corners inside the protective shell 201. The spring 204 is arranged between the protective shell 201 and the fastening block 203. A clamping component 500 is arranged on the inner wall of the protective shell 201;

[0031] A support component 300 is arranged at the rear side of the protective shell 201. The support component 300 includes a support leg 301 and a rotating block 303. The support leg 301 is located at the rear side of the protective shell 201. The rotating block 303 is fixed on both sides of the upper end of the support leg 301;

[0032] A handle 400 is arranged at the rear side of the protective shell 201. Connection ends 401 are arranged on the left and right sides of the handle 400. A fixed frame 402 is arranged outside the connection ends 401.

[0033] Further, in this embodiment, the clamping component 500 includes a clamping plate 501. An expansion joint 502 is opened on the outer side of the clamping plate 501. A fastening plate 503 is fixed at one end of the outer side of the clamping plate 501.

[0034] In this embodiment, the clamping plate 501 is designed in a U shape, and the opening of the clamping plate 501 is designed with a reduced opening. The size of the fastening plate 503 is adapted to the expansion joint 502. The upper end of the fastening plate 503 is movably connected to the clamping plate 501 through the expansion joint 502. The expansion joint 502 facilitates the upper end of the fastening plate 503 to move on the clamping plate 501.

[0035] In this embodiment, both the clamping plate 501 and the fastening plate 503 are made of elastic materials. After drawing papers of a certain thickness and quantity are placed, the constricted opening of the clamping plate 501 will be expanded, and the upper end of the fastening plate 503 will be extruded and move outward. Due to the materials of the clamping plate 501 and the fastening plate 503, the clamping plate 501 and the fastening plate 503 will closely adhere to the outside of the drawing papers.

[0036] In this embodiment, reinforcing blocks 202 are provided at the four corners of the protective shell 201. The fastening blocks 203 are located inside the reinforcing blocks 202. The reinforcing blocks 202, the fastening blocks 203, and the frame of the protective shell 201 are all made of silicone material, and the back plate of the protective shell 201 is made of engineering plastic material. Due to the materials of the reinforcing blocks 202, the fastening blocks 203, and the protective shell 201, it has a certain buffering and protective performance. The hardness of the protective shell 201 is increased through the material of the back plate, which plays a role in shaping the frame and the reinforcing blocks 202.

[0037] In this embodiment, the fastening block 203 is designed in an arc shape. Both ends of the spring 204 are fixedly connected to the fastening block 203 and the reinforcing block 202 respectively, and a guide post 205 is arranged inside the spring 204.

[0038] In this embodiment, an activity groove for the spring 204 to expand and contract and the guide post 205 to move is opened inside the reinforcing block 202. The guide post 205 is made of rubber material, and the guide post 205 is in threaded fit with the fastening block 203 and the reinforcing block 202 respectively. The activity groove is separately arranged for the spring 204 and the guide post 205 to avoid the deformation of the spring 204 or the guide post 205 affecting the use of each other. Through the activity groove, when the fastening block 203 moves backward, the spring 204 and the guide post 205 have space for expansion and contraction, avoiding excessive extrusion deformation.

[0039] In this embodiment, a storage groove 302 adapted to the support leg 301 is opened at the rear side of the protective shell 201. A rotation groove adapted to the rotation block 303 is opened inside the storage groove 302. The support leg 301 is rotatably connected to the protective shell 201 through the rotation groove. A rubber - material cushion block 304 is fixed at the bottom end of the support leg 301. Through the storage groove 302, when the support leg 301 is not in use, it can be stored at the rear side of the protective shell 201. Through the rotation groove, it is convenient for the support leg 301 to rotate around the rotation block 303 at the rear of the protective shell 201 to adjust the support angle, and the rotation groove is in threaded fit with the rotation block 303 for stable support.

[0040] In addition, considering the fixed position of the support leg 301 during storage, silicone is provided on the inner side of the bottom of the support leg 301 and bonded to the protective shell 201. Moreover, the silicone has a low cost and is convenient for replacement after the adhesiveness fails. Considering the problem that the rotation block 303 needs to be fixed during support, the thread between the rotation groove and the rotation block 303 can be set as a self - locking thread. Due to its shape characteristics, it can provide a large frictional force to prevent sliding.

[0041] In this embodiment, the fixed frame 402 is in threaded cooperation with the rear side of the protective case 201. The connecting end 401 penetrates through the fixed frame 402 and is movably connected to the fixed frame 402. The handle 400 is inserted into the protective case 201 through the connecting end 401. The two ends of the handle 400 are framed by the fixed frame 402, and a convex block and a groove are provided for insertion between the connecting end 401 of the handle 400 and the fixed frame 402. The connecting end 401 and the protective case 201 are also provided with such a setting for insertion. The fixed frame 402 strengthens the firmness of the handle 400, preventing the handle 400 from being loosely connected to the protective case 201 and causing the drawing tablet 100 to fall off.

[0042] Specifically, when using the electronic drawing tablet 100 to draw construction drawings at the construction site, the protective case 201 is framed outside the drawing tablet 100. When the drawing tablet 100 is placed, the fastening blocks 203 at the four corners of the protective case 201 are squeezed and move backward. At the same time, the springs 204 and the guide posts 205 behind the fastening blocks 203 are squeezed and move into the movable grooves in the reinforcing blocks 202. Based on the elastic force, the fastening blocks 203 are tightly attached to the outside of the drawing tablet 100, achieving a fixing effect.

[0043] Then, according to the needs, choose to hold it for drawing or place it for drawing. When holding it for drawing, the staff passes one hand through the handle 400, and the drawing tablet 100 is placed flat in the hand, and is stabilized by the handle 400 for hand-held drawing. When placing it for use, find a suitable position at the construction site, pull out the support legs 301 at the rear side of the protective case 201, and use the rotating block 303 to adjust to a suitable angle for support. The cushion blocks 304 made of rubber material at the bottom ends of the support legs 301 are used for position stabilization.

[0044] Considering that the drawing tablet 100 may not be applicable to all construction drawings, for this reason, a detachable clamping assembly 500 is inserted on the inner wall of the protective case 201. A convex block is provided at the rear end of the clamping plate 501, and a suitable groove is opened in the protective case 201 for insertion. Based on the fact that the back plate of the protective case 201 is made of a hard material, at this time, the back plate serves as a drawing board. A certain number of drawing papers are placed inside the clamping plate 501. The constricted part of the clamping plate 501 is expanded, and the upper end of the fastening plate 503 is squeezed and moves outward. Based on the materials of the clamping plate 501 and the fastening plate 503, the clamping plate 501 and the fastening plate 503 will be tightly attached to the outside of the drawing paper to clamp the drawing paper for manual drawing use.

[0045] The drawing tablet 100, protective case 201, reinforcing block 202, fastening block 203, spring 204, guide post 205, support leg 301, rotating block 303, cushion block 304, handle 400, connection end 401, fixed frame 402, clamping plate 501, and fastening plate 503 of the present utility model are all common standard parts or parts known to those skilled in the art. Their structures and principles can all be learned by those skilled in the art through technical manuals or by conventional experimental methods.
