The present utility model belongs to the technical field of land space planning. The purpose of the present utility model is to solve the problem in the prior art that the current drawing design device for land space planning does not have the function of height adjustment, cannot adjust the height of the drawing placement plate according to the height of the user, has large usage restrictions, and is very impractical.

[0003] The device achieves the purpose of fixing the drawing by using a cylinder to drive the connecting block to move to one side, and drives the fixing plate to move to one side through the connecting block, and stops when it moves to the specified position. However, although the use of a cylinder to compress and fix a relatively light object such as a drawing can achieve a fixing effect, the high pressure of the cylinder may damage the drawing, and additional power is consumed when the cylinder is driven. In addition, the controller for controlling the cylinder is set on one side of the connecting box. At this time, when placing the drawing on the drawing placement plate, it is necessary to bend down to operate the controller, which is more inconvenient.

[0004] Therefore, the utility model provides a drawing design device to solve the above problems. Utility Model Content

For those of ordinary skill in the art, the specific meanings of the above terms in this application can be understood according to specific circumstances.

[0031] The present application will be further described in detail below with reference to the accompanying drawings and examples.

[0032] Reference Figures 1 to 7 The embodiment of the present application provides a drawing design device, including a base 1, a height adjustment component 2 is provided on the top of the base 1; a limiting component 3 is provided at one end of the height adjustment component 2; the limiting component 3 includes a mounting frame 31, a placing plate 32 is rotatably connected between the inner walls of the mounting frame 31, one side of the placing plate 32 is fixedly connected to a concave frame 33, the interior of the concave frame 33 is slidably connected to a sliding rod 34, one end of the sliding rod 34 is fixedly connected to a connecting rod 35, and the other end of the sliding rod 34 is fixedly connected to a pressure plate 36, a spring 37 is fixedly connected between the pressure plate 36 and the inner wall of the concave frame 33. A limiting groove 38 is provided inside the mounting frame 31, and a limiting slider 310 is slidably connected to the internal surface of the limiting groove 38. A limiting ring 39 is fixedly connected to one side of the placing plate 32, and one end of the limiting slider 310 can be stuck in the groove of the limiting ring 39, and an insertion rod 311 is fixedly connected to the bottom of the mounting frame 31.

[0033] During specific implementation: by pulling the connecting rod 35, the sliding rod 34 and the pressure plate 36 are driven to move to one side. At the same time, the spring 37 is compressed, and the drawing is placed on the placement plate 32. After straightening, the connecting rod 35 is released. At this time, the spring 37 releases the elastic force to bounce the pressure plate 36 back. The elastic force of the spring 37 makes the pressure plate 36 press the drawing, and then the other end of the drawing is pressed and fixed in the same way. The whole process is simple to operate. The placement plate 32 can be rotated. When it is adjusted to the appropriate position, the limit ring 39 and the placement plate 32 can be fixed by clamping one end of the limit slider 310 in the groove of the limit ring 39.

[0034] Reference Figures 1 to 7 In one aspect of this embodiment, the height adjustment assembly 2 includes a protective cylinder 21, which is fixedly connected to the top of the base 1. A screw 22 is rotatably connected between the protective cylinder 21 and the base 1, and a nut block 27 is threadedly connected to the outer wall of the screw 22. An extension rod 28 is fixedly connected to the top of the nut block 27, which passes through the top of the protective cylinder 21 and is movably connected. The insertion rod 311 is inserted into the interior of the extension rod 28. There are two extension rods 28 symmetrically distributed on both sides of the screw 22. A worm gear 23 is fixedly connected to the outer wall of the screw 22, and an auxiliary block 24 is fixedly connected to the outer wall of the protective cylinder 21. A worm 25 is rotatably connected between the two auxiliary blocks 24. One end of the worm 25 is fixedly connected to a turntable handle 26.

[0035] During specific implementation: by rotating the turntable handle 26, the worm 25 is driven to rotate, and the worm 25 can drive the worm wheel 23 to rotate, and the worm wheel 23 drives the screw 22 to rotate. Due to the special shape of the nut block 27, the inner wall of the protective cylinder 21 will restrict it and prevent it from rotating with the screw 22. The screw 22 will then prompt the nut block 27 to move up and down, and the nut block 27 will also move up and down with the extension rod 28 to achieve height adjustment of the limiting component 3, and the insertion rod 311 inserted into the extension rod 28 also facilitates disassembly and installation.

[0036] Working principle: by pulling the connecting rod 35, the sliding rod 34 and the pressure plate 36 are moved to one side, and at the same time, the spring 37 is compressed, and the drawing is placed on the placement plate 32, and the connecting rod 35 is released after it is straightened. At this time, the spring 37 releases the elastic force to rebound the pressure plate 36, and the pressure plate 36 is pressed against the drawing by the elastic force of the spring 37. Then, the other end of the drawing is pressed and fixed in the same way. The whole process is simple to operate, and the placement plate 32 can be rotated. When it is adjusted to the appropriate position, the limit ring 39 and the limit ring 39 can be fixed by clamping one end of the limit slider 310 in the groove of the limit ring 39. The plate 32 is placed for fixing, and the worm 25 is driven to rotate by rotating the turntable handle 26, and the worm 25 can drive the worm wheel 23 to rotate, and the worm wheel 23 drives the screw 22 to rotate. Due to the special shape of the nut block 27, the inner wall of the protective cylinder 21 will restrict it and prevent it from rotating with the screw 22. The screw 22 will then prompt the nut block 27 to move up and down, and the nut block 27 will also move up and down with the extension rod 28 to achieve height adjustment of the limiting component 3, and it is also convenient for disassembly and installation by inserting the rod 311 into the extension rod 28.
