Description

Technical Field

[0001] The utility model relates to the technical field of urban planning display, in particular to a device for three-dimensional space analysis of urban planning. Background Art

[0002] Urban planning is a set of rules and plans formulated to make cities cleaner, more orderly, and more livable. By planning the city's roads, buildings, public facilities, etc., the city can better serve residents and improve their quality of life. When analyzing the three-dimensional space of urban planning, a three-dimensional model projector is needed.

[0003] However, the 3D model projectors of most existing urban planning 3D space analysis devices are directly exposed and mounted on brackets. When not in use, the 3D model projectors cannot be protected. The lenses of the 3D model projectors are easily adhered to by dust, which affects subsequent analysis. During carrying or transportation, the exposed 3D model projectors are at risk of being damaged by bumps, which reduces the service life of the 3D model projectors. To this end, we propose a device for urban planning 3D space analysis. Utility Model Content

[0004] The purpose of the utility model is to provide a device for three-dimensional spatial analysis of urban planning to solve the problems raised in the above background technology.

[0005] In order to achieve the above purpose, the utility model provides the following technical solutions:

[0006] A device for three-dimensional spatial analysis of urban planning comprises a protection box and a three-dimensional model projector, wherein two groups of rotatably connected top covers are arranged on the top of the protection box, a hand wheel is installed on the left outer wall of the protection box, and the output end of the hand wheel is connected to a bidirectional screw rod, the bottom end of the bidirectional screw rod is rotatably connected to the right inner wall of the protection box through a bearing, and two groups of threaded seats are threadedly connected on the bidirectional screw rod, and a limiting assembly is arranged at the bottom of the two groups of threaded seats, and a lifting platform is slidably connected to the inner wall of the protection box, and the bottom of the lifting platform and the tops of the two groups of threaded seats are both connected to hinge seats, and support rods are connected between the upper and lower adjacent hinge seats, and an angle adjustment unit is arranged on the lifting platform, and the angle adjustment unit comprises a rotating toothed disc, and the bottom of the rotating toothed disc is rotatably connected to the lifting platform through a bearing, and the three-dimensional model projector is located on the upper surface of the rotating toothed disc.

[0007] Further: the limiting component includes a fixing rod, the fixing rod is located on the bottom wall of the inner cavity of the protection box, and the fixing rod is slidably connected with two sets of sliding sleeves, and the tops of the two sets of sliding sleeves are respectively connected to the bottoms of the two sets of threaded seats.

[0008] Further: the angle adjustment unit includes an L-shaped plate, the L-shaped plate is located on the left side of the upper surface of the lifting platform plate, and a turntable is provided on the top of the L-shaped plate, a rotating shaft is connected to the bottom of the turntable, and a driving gear is installed at the bottom of the rotating shaft, and the driving gear is meshed and connected with the rotating gear disc.

[0009] Furthermore: both ends of the front and rear outer walls of the protection box are connected with ear plates, and the ear plates are rotatably connected to the outer wall of the top cover through a rotating shaft.

[0010] Furthermore: a magnetic layer is arranged on the side wall of the left top cover, and an iron sheet matched with the magnetic layer is arranged on the side wall of the right top cover. Both sets of top covers are provided with handles, and the hand-held ends of the handles are covered with anti-slip rubber sleeves.

[0011] Furthermore: the lower surface of the protection box is connected to a non-slip bottom plate, and the lower surface of the non-slip bottom plate is provided with a damping pad.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The utility model can drive the bidirectional screw to rotate by rotating the hand wheel. After the two sets of threaded seats connected with the bidirectional screw are limited by the sliding of the fixed rod and the sliding sleeve, the hinged seats at the top of the two sets of threaded seats move in relative or opposite directions. With the support rods hinged between the upper and lower adjacent hinged seats, the three-dimensional model projector on the lifting platform can be raised and lowered. When the three-dimensional model projector for urban planning three-dimensional space analysis is not in use, it can be stored in the protective box to avoid damage to the three-dimensional model projector, and at the same time facilitate the carrying of the urban planning three-dimensional space analysis device;

[0014] 2. The rotation of the turntable can drive the driving gear to rotate. Since the driving gear is meshed with the rotating gear plate, and the rotating gear plate is rotatably connected with the lifting platform, the three-dimensional model projector on the lifting platform rotates, and the angle of the urban planning three-dimensional space analysis device can be adjusted, thereby improving practicality.

Before use, open the two sets of top covers 3, and install the three-dimensional model projector 8 on the rotating gear plate 16. When the three-dimensional model projector 8 is not in use, the two-way screw rod 10 is reversed by rotating the hand wheel 9, and the three-dimensional model projector 8 on the lifting platform 7 is moved down and stored in the lifting platform 7 through the action of the sliding limit of the threaded seat 11 and the sliding sleeve 13, the fixed rod 12, and the hinged support rod 15 in the hinged seat 14. Protect the inside of the box 1 and then close the two sets of top covers 3 to prevent the lens of the three-dimensional model projector 8 from getting dusty or damaged, and at the same time facilitate the carrying of the urban planning three-dimensional space analysis device; when the three-dimensional model projector 8 is in use, open the two sets of top covers 3, rotate the hand wheel 9 in the opposite direction, and make the two-way screw rod 10 rotate forward, so that the three-dimensional model projector 8 on the lifting platform 7 moves up, and the three-dimensional model projector 8 can project the three-dimensional space of urban planning after it is raised, which is convenient for analysis.
