[0021] In order to make the technical solution of the present invention more clear and specific to those skilled in the art, the present invention is further described in detail below in conjunction with embodiments and drawings, but the implementation methods of the present invention are not limited thereto.

[0022] like Figure 1-Figure 4 As shown, the present embodiment provides an exhibition device for garden planning, including a display board 4, which has a hollow structure inside. An extension component 5 is installed in the middle of the display board 4, and the extension component 5 is composed of a gear 510, an extension plate, a fixing hole 502, a rack 512, a knob 505, a guide rail 511, a reinforcement rod 504 of a telescopic structure, a connecting rod 507, a limiting rod 508 of a telescopic structure, a positioning rod 506 of a regular hexagonal structure, a hexagonal positioning hole 509 and the positioning rod 506.

[0023] The gear 510 is rotatably mounted inside the display board 4 , the knob 505 penetrates through the back wall of the display board 4 and is fixedly connected to the gear 510 , the positioning hole 509 is formed on the knob 505 , and the knob 505 can drive the gear 510 to rotate.

[0024] The guide rail 511 is fixed at the upper and lower ends of the display board 4 by screws, the rack 512 is slidably connected to the guide rail 511, the gear 510 is meshed with the rack 512, and the rack 512 is distributed on both sides of the gear 510. Since the two groups of racks 512 are distributed on both sides of the gear 510, the gear 510 can drive the two groups of racks 512 to move in opposite directions, thereby pushing the expansion board 501 to move, and realizing synchronous adjustment of the two groups of expansion boards 501. The guide rail 511 guides the movement of the rack 512.

[0025] One end of the rack 512 is fixedly connected to a connecting column 503 that passes through the display board 4, and the other end of the connecting column 503 is fixedly connected to the expansion board 501. The fixed part of the reinforcement rod 504 is fixedly connected to the inner wall of the display board 4, and the movable wall of the reinforcement rod 504 passes through the display board 4 and is fixedly connected to the expansion board 501. The reinforcement rod 504 can provide auxiliary support for the expansion board 501, and can also be extended and retracted along with the expansion board 501.

[0026] The limiting rod 508 is rotatably mounted on the back wall of the display board 4, the connecting rod 507 is fixed on the movable end of the limiting rod 508, the positioning rod 506 is connected to the other end of the connecting rod 507 by a screw, and the specifications of the positioning rod 506 and the positioning hole 509 match. After adjustment, the limiting rod 508 is rotated to adjust the positioning rod 506 to the positioning hole 509, and then the positioning rod 506 is placed in the positioning hole 509 by adjusting the length of the limiting rod 508, thereby achieving fixation of the adjusted position.

[0027] A supporting column 3 of a telescopic structure is fixed to the bottom end of the display board 4 , and a base 1 is fixed to the bottom end of the supporting column 3 by bolts. The supporting column 3 can adjust the height of the display board 4 .

[0028] Universal wheels 2 are installed at the four corners of the bottom end of the base 1 by bolts, and the universal wheels 2 are convenient for moving the device.

[0029] The working principle of this device is as follows: the device is moved to the display position through the universal wheel 2, and then when the expansion board 501 is adjusted according to the specifications of the garden planning poster, it is only necessary to drive the gear 510 to rotate through the knob 505. Since the two sets of racks 512 are distributed on both sides of the gear 510, the gear 510 can drive the two sets of racks 512 to move in opposite directions, thereby pushing the expansion board 501 to move, and the two sets of expansion boards 501 can be adjusted synchronously. After the adjustment, the adjusted position can be fixed by the positioning rod 506 and the positioning hole 509, and then the garden planning poster is posted on the display board 4 and fixed at the four corners through the fixing holes 502.
