Description

Technical Field

[0001] The utility model belongs to the technical field of sand table display platforms, in particular to a model sand table display turntable for planning infrastructure. Background Art

[0002] Capital construction refers to the expanded reproduction of fixed assets carried out by various sectors of the national economy to develop production, that is, the general term for the construction, purchase and installation work carried out by various sectors of the national economy to increase the surface of fixed assets. For example, the new construction, reconstruction, expansion and restoration of roads, railways, bridges and various industrial and civil buildings, as well as the purchase and installation of machinery, equipment, vehicles and ships and related work are all called capital construction. Capital construction planning often needs to be displayed through a sand table booth.

[0003] For example, the publication (announcement) number: CN214752568U discloses a model sand table display turntable for planning infrastructure. Compared with the existing utility model, the device can install multiple sand table models. When multiple sand table models need to be compared, it is only necessary to adjust the assembly through the cooperation of the linkage assembly to rotate the two mounting plates, so that another group of sand table models that need to be compared can be displayed. When viewing, it is only necessary to view around the device. It is convenient to view and takes up little space. The design of the installation box allows the model sand table to be located inside the protective box by moving the return plate when not in use, which is more practical.

[0004] However, there are still some shortcomings: the display height of the sand table is fixed and cannot be adjusted. Dust is easily trapped in the sand table during the display process. Dust accumulates over a long period of time and is difficult to clean, affecting the effect of the sand table display. Therefore, improvements are needed. Utility Model Content

One end of the spring is fixed to the end plate and the other end is arranged on the side wall of the sandbox booth. The locking device can realize the locking and fixation of the cover, and it is also convenient to disassemble the cover. The cover can protect the sandbox booth from dust.

[0007] Furthermore, the supporting device includes a side plate, which is fixed to the side wall of the base. A hydraulic cylinder 2 is provided on the side plate, and a support plate is provided at the output end of the hydraulic cylinder 2. The base can be supported by the supporting device, making it more stable when the planned infrastructure model is displayed on a sand table.

[0008] Preferably, a limit plate is provided at the upper end of the guide column, and the limit plate can prevent the guide cylinder from separating from the guide column.

[0009] Preferably, the bottom of the base is provided with running wheels.

[0010] Preferably, the frame is provided with an armrest.

[0011] Preferably, when the insertion rod is inserted into the socket, the spring can exert an elastic force on the pin rod to insert into the pin hole.

[0012] Preferably, the supporting devices are provided in a plurality of groups in a circumferential array on the outer wall of the base.

[0013] The utility model adopts the above structure to achieve the following beneficial effects:
