[0022] The following description is used to disclose the present invention so that those skilled in the art can implement the present invention. The preferred embodiments described below are only examples, and those skilled in the art may think of other obvious variations.

[0023] Reference Figures 1 to 5 As shown, a drawing display board for urban and rural planning includes a box-type paper loading mechanism and a retractable supporting mechanism;

[0024] The box-type paper loading mechanism comprises a cavity box body 1, one side and the bottom of the cavity box body 1 are both open, a lower display board 2 is hinged to one side of the open end of the bottom of the cavity box body 1, and a side display board 3 is hinged to the end of the lower display board 2, and the cavity box body 1, the lower display board 2 and the side display board 3 as a whole can form a rectangular box with a cavity inside;

[0025] By setting up the box-type paper loading mechanism, the side display panels 3 and the lower display panels 2 are flipped in turn, and the side display panels 3 and the lower display panels 2 are flipped to be in the same vertical plane with the cavity box body 1, so that large-scale drawing papers can be conveniently pasted on the surfaces of the cavity box body 1, the lower display panels 2 and the side display panels 3. Conversely, the lower display panels 2 and the side display panels 3 are flipped in the opposite direction in the same way, and the bottom and side openings of the cavity box body 1 are respectively covered, so that the cavity box body 1, the lower display panels 2 and the side display panels 3 form a rectangular box as a whole, so that the volume of the device can be reduced and it is convenient to carry, and small-scale drawing papers can be conveniently pasted on the sides of the cavity box body 1 or the side display panels 3.

[0026] Further, refer to Figure 1 and Figure 3 As shown, first magnetic strips (not shown) are fixed on both end surfaces of the lower display board 2, and second magnetic strips (not shown) matching the first magnetic strips are fixed on the cavity box 1 and the side display board 3 corresponding to the side of the lower display board 2;

[0027] By setting the magnetic strip, when a large drawing needs to be displayed, the lower display board 2 and the side display board 3 are flipped to be on the same plane as the side of the cavity box 1, and the magnetic adsorption of the magnetic strip between the cavity box 1, the lower display board 2 and the side display board 3 ensures the flatness and stability of the display board.

[0028] Further, refer to Figure 1 and Figure 2 As shown, two lock cards 8 are symmetrically fixed on the end of the side display plate 3, and threaded bolts 9 are threadedly penetrated on the lock cards 8, and threaded holes matching with the threaded bolts 9 are opened on the top surface of the cavity box body 1;

[0029] Through the arrangement of the locking card 8 and the threaded bolt 9, when the side display panel 3 is rotated in the opposite direction to cover the side opening of the cavity box body 1, the locking card 8 can be synchronously flipped along with the side display panel 3 to a position in contact with the top surface of the cavity box body 1, and then the knob threaded bolt 9 is turned to make the threaded bolt 9 pass into the threaded hole under the threaded structure, so as to lock the side display panel 3 and the lower display panel 2, thereby ensuring the stability of the rectangular box structure formed by the cavity box body 1, the lower display panel 2 and the side display panel 3.

[0030] Further, refer to Figure 1 , Figure 3 and Figure 4 As shown, it is worth noting that the retractable support mechanism includes a bottom plate 5 slidably disposed inside the cavity box 1 and a lifting component disposed above the bottom plate 5, and a plurality of suction cups 6 are equidistantly fixed on the bottom surface of the bottom plate 5;

[0031] By setting up the retractable support mechanism, when it is necessary to display a large-scale drawing, the bottom plate 5 is pushed by the lifting component until the bottom plate 5 touches the ground, and the suction cup 6 is squeezed and adsorbed on the ground, thereby forming an auxiliary support for the cavity box 1, the lower display board 2 and the side display board 3 as a whole, and ensuring the stability of the three on the ground. In addition, the bottom plate 5 and the suction cup 6 are retracted as a whole to the inside of the cavity box 1 by the lifting component, that is, relative to the fixed structure of the display board bracket in the prior art, the device can be retracted and hidden, further reducing the volume and making it convenient to carry.

[0032] Further, refer to Figures 3 to 5 As shown, the lifting component includes a scissor bracket 13 arranged above the bottom plate 5 and a ceiling plate 7 fixed on the inner wall of the top end of the cavity box body 1, both ends of the top of the scissor bracket 13 are hinged with a moving block 11, a transmission T-shaped slider 12 is fixed on the top of the moving block 11, and both ends of the bottom of the scissor bracket 13 are hinged with an auxiliary T-shaped slider 14, and the bottom end of the ceiling plate 7 and the inner wall of the bottom end of the cavity box body 1 are provided with T-shaped slide grooves adapted to the transmission T-shaped slider 12 and the auxiliary T-shaped slider 14;

[0033] The lifting component also includes a bidirectional lead screw 10 which is transversely arranged inside the cavity box 1, one end of which is rotatably connected to the inner wall of one side of the cavity box 1, and the other end of which is rotatably passed through the cavity box 1 and is tightly sleeved with a turntable 4, and two moving blocks 11 are symmetrically threadedly connected to the rod of the bidirectional lead screw 10;

[0034] By setting the lifting components and rotating the turntable 4, the bidirectional lead screw 10 is driven to rotate, and then the transmission T-shaped slider 12 on the moving block 11 is dragged to slide relatively in the T-shaped groove in the ceiling plate 7, so that the scissor bracket 13 is squeezed and extended downward, pushing the bottom plate 5 to move downward, and at the same time, the auxiliary T-shaped slider 14 slides synchronously in the T-shaped groove on the bottom plate 5, thereby realizing the movement of the bottom plate 5.
