DETAILED DESCRIPTION

[0023] The following will be combined with the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments of the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0024] like Figure 1 As shown, a drawing board stand for architectural planning and design comprises a fixed frame 1, a movable frame 2 is movably mounted on one side of the fixed frame 1, a driving mechanism 3 for controlling the movement of the movable frame 2 is arranged on one side of the fixed frame 1, a bottom plate 4 is installed at the bottom of the movable frame 2, a limiting mechanism 5 is arranged on the upper surface of the bottom plate 4, and supporting legs 6 are installed on both sides of one end surface of the fixed frame 1.

[0025] like Figure 2 , Figure 3 , Figure 4As shown, first mounting grooves 101 are provided on both sides of the surface of one end of the fixed frame 1, and the driving mechanism 3 includes a first adjusting screw rod 301 and a limiting rod 302. The first adjusting screw rod 301 is rotatably installed in one of the first mounting grooves 101, and the limiting rod 302 is installed in the other first mounting groove 101. One end of the first adjusting screw rod 301 passes through the top of the first mounting groove 101 and a first knob 303 is installed on the end thereof. A first screw rod sleeve 304 is movably installed on the rod body of the first adjusting screw rod 301, and a sliding block 305 is movably installed on the rod body of the limiting rod 302. One ends of the sliding block 305 and the first screw rod sleeve 304 are both slidably arranged in the first mounting groove 101 at corresponding positions, and the other ends of the sliding block 305 and the first screw rod sleeve 304 are respectively fixedly connected to one side surface of the movable frame 2.

[0026] Through the meshing transmission between the first adjusting screw rod 301 and the first screw rod sleeve 304, when the first knob 303 is turned, the height position of the mobile frame 2 can be adjusted to meet the usage requirements of users of different heights. Through the sliding cooperation between the sliding block 305 and the limiting rod 302, the moving trajectory of the mobile frame 2 can be limited, making the mobile frame 2 more stable during movement.

[0027] like Figure 4 , Figure 5 , Figure 6 As shown, second mounting grooves 401 are provided on both sides of the upper surface of the base plate 4, and the limiting mechanism 5 includes a second adjusting screw rod 501. Two second adjusting screw rods 501 are provided and are rotatably arranged inside the second mounting groove 401. One end of each second adjusting screw rod 501 passes through one end of the second mounting groove 401, and one end of each second adjusting screw rod 501 is installed with a second knob 502. A second screw rod sleeve 503 is movably installed on the rod body of each second adjusting screw rod 501, and the bottom of each second screw rod sleeve 503 is slidably arranged inside the second mounting groove 401 at a corresponding position. A limiting plate 504 is installed on the top of each second screw rod sleeve 503, and an anti-slip pad 505 is arranged on the surface of one side of each limiting plate 504.

[0028] Through the meshing transmission between the second adjusting screw rod 501 and the second screw rod sleeve 503, when the second knob 502 is turned, the limit plate 504 can be controlled to move, so that the two limit plates 504 can fix the bottom of the drawing board, which is convenient for the use of the drawing board. The anti-slip pad 505 is arranged on one side of the limit plate 504, which can make the limit plate 504 more stable when fixing the drawing board and will not slide.

[0029] The working principle of this architectural planning and design drawing board frame:

[0030] When in use, place the drawing board on one side of the mobile frame 2, and control the second adjusting screw rod 501 to rotate by turning the second knob 502. Under the meshing action between the second adjusting screw rod 501 and the second screw rod sleeve 503, the second screw rod sleeve 503 can drive the limiting plate 504 to move, so that the distance between the limiting plate 504 and the mobile frame 2 can be adjusted, and the bottom of the drawing board can be fixed for easy use. By turning the first knob 303, the first adjusting screw rod 301 is rotated. Under the meshing action between the first adjusting screw rod 301 and the first screw rod sleeve 304, the first screw rod sleeve 304 can drive the mobile frame 2 to move, thereby driving the clamped drawing board to move together. The height position of the drawing board can be adjusted according to the needs of different users, which is more convenient during use.
