Description

Technical Field

[0001] This utility model relates to the field of sand table technology, and in particular to an urban planning sand table. Background Technology

[0002] The city planning model presents the city layout in a miniature scale, with roads interwoven in a grid or ring pattern to divide different functional areas. Residential buildings are arranged in an orderly manner, commercial areas are filled with high-rise buildings, industrial areas are concentrated on the periphery, and public facilities such as parks, schools, and hospitals are scattered throughout. Rivers and railways run through the city, clearly showing the location relationship of various urban elements and the future development direction, providing an intuitive reference for urban planning and construction.

[0003] In urban planning work, lighting is usually installed to enable the model to be used normally in dark environments. However, it is currently very troublesome to fix or adjust the lighting area of ​​the model. It cannot be flexibly changed according to the needs of the display. The lighting intensity in some places is insufficient, and the details of the model cannot be seen clearly. This seriously affects the display effect of urban planning. Therefore, a new type of urban planning model has been proposed. Utility Model Content

[0004] The purpose of this utility model is to solve the shortcomings of the existing technology, such as the difficulty in fixing or adjusting the lighting area of ​​the sand table, the inability to flexibly change it according to the display needs, insufficient lighting intensity in some areas, and the inability to see the details of the sand table clearly. Therefore, a new urban planning sand table is proposed.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] A city planning model includes a sand table, a first support rod movably connected to the upper part of the sand table, a lighting lamp movably connected to the upper part of the sand table, a quick-fixing assembly for the lighting lamp provided between the sand table and the first support rod, the quick-fixing assembly including a slot opened on the side of the sand table and a fixing rod symmetrically and movably connected to the outside of the first support rod, a second support rod movably connected to the upper part of the sand table, a third support rod movably connected to the upper part of the sand table, and an adjustment assembly for the lighting lamp provided on the upper part of the sand table, the adjustment assembly including an adjustment block movably connected to the outside of the second support rod, a first adjustment ball fixedly connected to the end of the third support rod, and a second adjustment ball fixedly connected to the outside of the lighting lamp.

[0007] The above technical solution further includes:

[0008] A first spring is fixedly connected inside the slot. A movable baffle is fixedly connected to one end of the first spring near the first support rod. The movable baffle is movably connected to the first support rod. The movable baffle is supported by the first spring and is level with the sand table, so that the overall effect of the sand table is the same.

[0009] A fixing block is fixedly connected inside the first support rod, and the fixing rod is movably connected to the fixing block. A push rod is slidably connected to the outside of the fixing block, and the push rod is movably connected to the first support rod. The push rod is movably connected to the fixing rod through a connecting rod. A second spring is fixedly connected inside the first support rod, and the end of the second spring away from the sand table is fixedly connected to the push rod. The push rod opens the fixing rods on both sides through the connecting rod, so that the fixing rod is fixed in a wide area inside the slot, thereby fixing the lighting lamp in a suitable position for easy observation.

[0010] The second support rod is movably connected to the first support rod. A third spring is fixedly connected inside the second support rod, and the third spring is fixedly connected to the adjusting block. Multiple adjusting holes are opened on the outer side of the first support rod, and the adjusting block is movably connected to the adjusting holes.

[0021] Example

[0022] like Figures 1-4 As shown, the present invention proposes an urban planning sand table, including a sand table 1, a first support rod 2 movably connected to the upper part of the sand table 1, a lighting lamp 10 movably connected to the upper part of the sand table 1, a quick-fixing assembly for the lighting lamp 10 provided between the sand table 1 and the first support rod 2, the quick-fixing assembly including a slot 11 opened on the side of the sand table 1 and a fixing rod 15 symmetrically and movably connected to the outside of the first support rod 2, a second support rod 3 movably connected to the upper part of the sand table 1, a third support rod 7 movably connected to the upper part of the sand table 1, and an adjustment assembly for the lighting lamp 10 provided on the upper part of the sand table 1, the adjustment assembly including an adjustment block 18 movably connected to the outside of the second support rod 3, a first adjustment ball 6 fixedly connected to the end of the third support rod 7, and a second adjustment ball 21 fixedly connected to the outside of the lighting lamp 10.

[0023] A first spring 12 is fixedly connected inside the slot 11. A movable baffle 13 is fixedly connected to one end of the first spring 12 near the first support rod 2. The movable baffle 13 is movably connected to the first support rod 2. The movable baffle 13 is supported by the first spring 12 and is level with the sand table 1, so that the overall effect of the sand table is the same.

[0024] A fixing block 14 is fixedly connected inside the first support rod 2. The fixing rod 15 is movably connected to the fixing block 14. A push rod 17 is slidably connected to the outside of the fixing block 14. The push rod 17 is movably connected to the first support rod 2. The push rod 17 is movably connected to the fixing rod 15 through a connecting rod. A second spring 16 is fixedly connected inside the first support rod 2. The end of the second spring 16 away from the sand table 1 is fixedly connected to the push rod 17. The push rod 17 opens the fixing rods 15 on both sides through the connecting rod, so that the fixing rods 15 are fixed in a wide space inside the slot 11, thereby fixing the lighting lamp 10 in a suitable position for easy observation.

[0025] In this embodiment, the sand table 1 is provided with multiple sets of slots 11, a first spring 12, and a movable baffle 13, which are set next to the roads and houses in the urban sand table. The movable baffle 13 is supported by the first spring 12 and is level with the sand table 1, so that the overall effect of the sand table is the same. When it is necessary to move the lighting 10 to view a specific house, the first support rod 2 is moved to a suitable position so that the first support rod 2 is inserted into the slot 11. The insertion of the first support rod 2 compresses the movable baffle 13 and the first spring 12. When the bottom of the first support rod 2 is inserted into the bottom of the slot 11, the fixing rods 15 on both sides of the first support rod 2 move together with the first spring 12. The descending support rod 2 is compressed and retracted inside the first support rod 2 by the side of the slot 11. When it moves to a wide area inside the slot 11, the second spring 16 supports the push rod 17. The push rod 17 opens the fixing rods 15 on both sides through the connecting rod, so that the fixing rods 15 are fixed in the wide area inside the slot 11, thereby fixing the lighting lamp 10 in a suitable position for easy observation. When it is necessary to move the lighting lamp 10 to another position, the push rod 17 is pressed down, so that the push rod 17 pulls the fixing rod 15 back into the first support rod 2 through the connecting rod. At this time, pulling out the first support rod 2 can release the fixing effect. Example

[0026] like Figures 1-4 As shown, based on Embodiment 1, the second support rod 3 is movably connected to the first support rod 2. A third spring 19 is fixedly connected inside the second support rod 3. The third spring 19 is fixedly connected to the adjusting block 18. Multiple adjusting holes 20 are opened on the outer side of the first support rod 2. The adjusting block 18 is movably connected to the adjusting holes 20. The second support rod 3 moves on the first support rod 2, which can adjust the height of the lighting lamp 10 so that the lighting lamp 10 can provide illumination in a suitable position.

[0027] The second support rod 3 is fixedly connected to the first spherical shell 4 at the end away from the sand table 1. The first adjusting ball 6 is movably connected to the first spherical shell 4. The outer side of the first spherical shell 4 is threadedly connected to the first adjusting bolt 5. The end of the first adjusting bolt 5 near the first adjusting ball 6 is fixedly connected to a rubber block. The rubber blocks at the ends of the first adjusting bolt 5 and the second adjusting bolt 9 increase the friction with the contacting person and improve the stability of the fixed lighting lamp 10.

[0028] The third support rod 7 is fixedly connected to the end away from the first adjusting ball 6 with the second spherical shell 8. The second adjusting ball 21 is movably connected to the second spherical shell 8. The outer side of the second spherical shell 8 is threaded with the second adjusting bolt 9. The end of the second adjusting bolt 9 near the second adjusting ball 21 is fixedly connected with a rubber block. The second adjusting ball 21 moves inside the second spherical shell 8, allowing the lighting lamp 10 to rotate at any angle.

[0029] In this embodiment, when the height of the lighting lamp 10 needs to be adjusted, the adjusting block 18 is pressed down by hand, causing the adjusting block 18 to compress the third spring 19 and retract into the second support rod 3. At this time, the second support rod 3 is pulled upward by hand, and the compressed third spring 19 rebounds and the adjusting block 18 is fixed in the adjusting hole 20 on the outside of the first support rod 2, thereby adjusting the height of the lighting lamp 10. By moving the third support rod 7, the third support rod 7 drives the first adjusting ball 6 to move within the first spherical shell 4. By rotating the first adjusting bolt 5, the rubber block at the end of the first adjusting bolt 5 contacts the first adjusting ball 6, fixing the position after adjusting the third support rod 7, so that the lighting lamp 10 is in a suitable position. By rotating the lighting lamp 10, the lighting lamp 10 drives the second adjusting ball 21 to move within the second spherical shell 8. By rotating the second adjusting bolt 9, the rubber block at the end of the second adjusting bolt 9 contacts the second adjusting ball 21, thus fixing the adjusted lighting lamp 10. In this way, the lighting lamp 10 can be adjusted at multiple angles to reach a suitable position, illuminating the houses on the sand table at a suitable angle.
