[0025] To make the purpose, technical solution, and advantages of the present invention more clear, the technical solution of the present invention will be described in detail below. Obviously, the embodiments described are only some of the embodiments of the present invention, and not all of them. Based on the embodiments of the present invention, all other implementation methods obtained by ordinary technicians in this field without making any creative efforts are within the scope of protection of the present invention.

[0026] First embodiment:

[0027] See also Figures 1-6 As shown, the utility model provides a sand table for urban planning, comprising a stand 1, the top of which is rotatably connected to two sand table boards 2, and the surfaces of the two sand table boards 2 are provided with magnetic plates 201 that are magnetically attracted to the iron bottom sand table building;

[0028] The stand 1 is provided with a thrust frame 3 for pushing the sand table board 2 up and down, and the bottom end of the stand 1 is provided with a supporting base frame 5 for auxiliary support. When the device is in use, the stand 1 is used to support the sand table board 2, and the thrust frame 3 is used to push the sand table board 2 to a horizontal state, so as to support the sand table board 2. The magnetic plate 201 on the sand table board 2 is used to adsorb the building model, thereby achieving support and position limitation of the building model. The operation is simple and convenient, and the use effect is good.

[0029] Furthermore, the support base 5 is rotatably connected to the stand 1. When the support base 5 is rotated in the length direction to be perpendicular to the stand 1, the support base 5 can form a support for the stand 1, which is convenient for placing the device. When the support base 5 is rotated to be parallel to the stand 1 and the thrust frame 3 is used to rotate the sandbox board 2 to both sides of the stand 1, the entire device can be folded into a plate-like structure, which is convenient for storing and placing the device.

[0030] The stand 1 is in a "U"-shaped or frame-shaped structure, and the "U"-shaped or frame-shaped stand 1 is used to support the sand table board 2, which has a good supporting effect on the sand table board 2.

[0031] The second embodiment is different from the first embodiment in that:

[0032] The surface of the magnetic plate 201 is provided with a translucent light board 202 with matrix lamp beads. The translucent light board 202 can illuminate the building model on the surface, and the lamp beads on the translucent light board 202 are in a matrix shape, which is convenient for indicating the position of the building model.

[0033] The third embodiment is different from the first embodiment in that:

[0034] The thrust frame 3 includes two sliding sleeves 301, which are respectively slidably matched with the two vertical ends of the stand 1. A connecting rod 303 is connected between the two sliding sleeves 301. A connecting arm 4 is rotatably connected between the sliding sleeves 301 and the sand table board 2. When the connecting rod 303 is pulled, the sliding sleeves 301 on both sides of the connecting rod 303 can be pulled to slide outside the stand 1 at the same time, and the connecting arm 4 pushes the sand table board 2 to rotate. The connecting arm 4 can be adjusted to a horizontal position or folded on both sides of the stand 1.

[0035] In a preferred embodiment, the facing surfaces of the two sliding sleeves 301 are connected with threaded sleeves 302, and the inner sides of the threaded sleeves 302 are provided with threads with opposite rotation directions. The two ends of the connecting rod 303 are respectively threadedly matched with the two threaded sleeves 302. After rotating the connecting rod 303, the connecting rod 303 and the threaded sleeve 302 rotate, and the vertical end of the stand 1 will be slightly deformed. The inner end of the connecting rod 303 located at the sliding sleeve 301 is away from the stand 1, which releases the locking fixation of the thrust frame 3 and the stand 1. The connecting rod 303 can be used to pull the movement of the two sliding sleeves 301, so that the sliding sleeve 301 slides up and down on the outer side of the stand 1. After sliding to the desired position, the connecting rod 303 is rotated to move the threaded sleeve 302 toward the middle of the connecting rod 303, so that the inner end of the connecting rod 303 can contact the vertical side wall, thereby achieving locking fixation of the sliding sleeve 301.

[0036] Furthermore, anti-slip grooves are provided on the outer side of the connecting rod 303 .

[0037] The above description is merely a specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any modifications or substitutions that can be easily conceived by a person skilled in the art within the technical scope disclosed in the present invention should be included within the scope of protection of the present invention. Therefore, the scope of protection of the present invention should be based on the scope of protection of the claims.
