The embodiments described below with reference to the drawings are exemplary and are intended to explain the present utility model, but should not be construed as limiting the present utility model.

[0019] The first embodiment of this application is as follows:

[0020] Please refer to Figures 1-3 , Figure 1 which is a schematic diagram of the overall structure of a drawing board rack according to the first embodiment of the present utility model, Figure 2 Yes Figure 1 The enlarged view of part A of Figure 3 is a schematic connection diagram of the coupling shaft and the square column of the first embodiment of the present utility model.

[0021] The present utility model provides a drawing board rack: including a base 101, a drawing rack 102, a drawing board 103 and a storage device, and further including a fixing device. The fixing device includes a rotating plate 105, a coupling shaft 106, a sliding rack 107, a guide rod 108, a positioning post 109, a spring 110, a moving component and a rotating component. The moving component includes a moving block 111 and a driving member. The driving member includes a double-headed screw rod 113 and a rotating disc 114. The rotating component includes a square column 115, a sliding sleeve 116 and a limiting block 117. Through the foregoing solution, the problem that although the foregoing device can fix papers of different sizes, since the two adjusting rods are fixed by fastening bolts, when moving the adjusting rods, it is necessary to loosen and tighten multiple groups of fastening bolts multiple times to achieve this, which makes the fixing of papers relatively troublesome is solved. The foregoing solution can be used in the scenario of fixing drawings by the drawing board rack and can also be used to solve the problem of placing drawing tools.

[0022] In this embodiment, through the driving of the moving component and the rotating component, the positioning column 109 and the rotating plate 105 can quickly fix the side and top of the drawing.

[0023] Among them, the coupling shaft 106 is rotatably installed on the drawing board 103 through the rotating component and penetrates the drawing board 103. The rotating plate 105 is fixedly installed on the coupling shaft 106. The sliding frame 107 is slidably installed on the drawing board 103 through the moving component. The guide rod 108 is fixedly installed on the sliding frame 107. The spring 110 is sleeved on the guide rod 108 and fixedly connected to the sliding frame 107. The positioning column 109 is slidably matched with the guide rod 108 and is fixedly connected to the spring 110 at the same time. The drawing frame 102 is in a herringbone shape. There is a certain inclination angle between the drawing board 103 and the base 101. The rotating plate 105 is a square plate structure. The coupling shaft 106 penetrates the rotating plate 105. The number of the sliding frame 107, the guide rod 108, the positioning column 109 and the spring 110 is two groups and they are symmetrically arranged on both sides of the drawing board 103. The sliding frame 107 is in an L shape. The guide rod 108 is in a cylindrical structure. The length of the positioning column 109 is greater than the length of the guide rod 108. The spring 110 is located between the positioning column 109 and the sliding frame 107. The moving component can drive the sliding frame 107 to move. The rotating component can drive the coupling shaft 106 to rotate. When the drawing needs to be fixed, the rotating component drives the coupling shaft 106 to drive the rotating plate 105 to rotate, so that the rotating plate 105 fixes the top of the drawing, and the moving component drives the two sliding frames 107 on both sides to be adjusted above the two sides of the drawing. Through the elastic force of the spring 110, the positioning column 109 fixes the side of the drawing, thus realizing the quick fixing of the drawing, and the fixing process is relatively convenient.

[0024] Secondly, a moving groove 112 is provided on one side of the drawing board 103 close to the groove 104. The moving block 111 is slidably installed on the drawing board 103 through the driving member and is located in the moving groove 112. The number of the moving blocks 111 is two groups and they are symmetrically distributed on both sides of the moving groove 112. A threaded hole is provided inside the moving block 111. The driving member can drive the moving block 111 to move. When in use, the driving member drives the two moving blocks 111 to move towards or away from each other along the moving groove 112 at the same time, so that the sliding frame 107 fixedly connected to them moves synchronously, thus realizing the moving effect of the sliding frame 107.

[0025] Again, the double-headed screw 113 is rotatably installed on the drawing board 103 and penetrates through the moving groove 112. At the same time, the double-headed screw 113 is threadedly penetrated through the moving block 111. The rotating disk 114 is fixedly installed on the double-headed screw 113. The thread rotation directions at both ends of the double-headed screw 113 are opposite. The rotating disk 114 is of a disk structure and is arranged at the end of the double-headed screw 113. The two moving blocks 111 are symmetrically arranged at both ends of the double-headed screw 113. During use, rotating the rotating disk 114 drives the double-headed screw 113 to rotate. The double-headed screw 113 drives the two moving blocks 111 to move towards or away from each other simultaneously through threaded cooperation, thereby realizing the movement of the moving block 111.

[0026] Finally, the square column 115 is fixedly installed on the coupling shaft 106. The sliding sleeve 116 is slidably installed on the square column 115. A square groove 118 is provided on one side of the drawing board 103 close to the coupling shaft 106. The sliding sleeve 116 is snapped into the square groove 118. The limiting block 117 is fixedly installed on the square column 115. The square column 115 is square-shaped, and the axis of the square column 115 coincides with the axis of the coupling shaft 106. The sliding sleeve 116 is a square sleeve. When the rotating plate 105 contacts the bottom wall of the groove 104, the sliding sleeve 116 can just enter the square groove 118. The limiting block 117 is fixed to the end of the square column 115 by screws. Through the setting of the sliding sleeve 116, the coupling shaft 106 can be fixed. Through the setting of the limiting block 117, the sliding sleeve 116 can be prevented from separating from the square column 115. During use, rotating the sliding sleeve 116 causes the square column 115 to rotate, and the square column 115 drives the coupling shaft 106 to rotate, thereby realizing the drive of the coupling shaft 106.

[0027] In this embodiment, when in use, pull out the sliding sleeve 116 so that the sliding sleeve 116 is disengaged from the square groove 118. Then, rotate the connecting shaft 106 through the sliding sleeve 116, so that the connecting shaft 106 drives the rotating plate 105 to rotate, so that the rotating plate 105 no longer contacts the bottom wall of the groove 104. Then, place the drawing paper in the groove 104. Then, rotate the connecting shaft 106 again, so that the connecting shaft 106 drives the rotating plate 105, so that the rotating plate 105 fixes the top of the drawing paper. Immediately, slide the sliding sleeve 116 again so that the sliding sleeve 116 enters the square groove 118. At this time, the fixing of the rotating plate 105 is achieved. Then, according to the size of the drawing paper, adjust the distance between the two sliding frames 107. Rotate the rotating disk 114 to drive the double-headed screw 113 to rotate. The double-headed screw 113 drives the two moving blocks 111 to move in opposite or reverse directions along the moving groove 112 through the threaded cooperation with the moving blocks 111. The movement of the moving blocks 111 drives the sliding frames 107 to move synchronously. During the movement of the sliding frames 107, lift the positioning column 109 upward so that the spring 110 is compressed. When the positioning column 109 is above the side edge of the drawing paper, release the positioning column 109 so that the spring 110 pushes the positioning column 109 to press on both side edges of the drawing paper, thus realizing the quick fixing of the drawing paper, and the fixing process is relatively convenient.
