Description

Technical Field

[0001] This utility model relates to the field of surveying and mapping, and in particular to a surveying and mapping device for urban planning and design. Background Technology

[0002] In modern industrial production, scientific research, and environmental monitoring, the application of various instruments and equipment is becoming increasingly widespread. These instruments and equipment often need to be installed and used in different ground environments, and when operating outdoors, they are affected by complex environmental factors such as direct sunlight, wind and sand erosion, and dust pollution.

[0003] Currently, existing related instruments and equipment have certain limitations in terms of installation and protection. During installation, the assembly of the upper and lower parts of the equipment often requires complex tools and cumbersome procedures, resulting in low installation efficiency and high technical requirements for installers, leading to increased installation costs and longer installation times. Regarding protection, most instruments lack effective protective structures. When outdoors, direct sunlight can cause glare on the instrument's operating interface, interfering with operator readings; windblown sand and dust can directly enter the instrument, causing wear and contamination of delicate components, affecting the instrument's performance and lifespan. Furthermore, existing protective structures, if designed with an unfolding mechanism, suffer from poor stability in the transmission system during unfolding and closing, prone to jamming and malfunctions. The structural layout is also not ideal, occupying a large space and hindering the transportation, storage, and relocation of the equipment. Therefore, there is an urgent need to design an instrument or equipment that can be quickly assembled, stably installed, and possesses good protective performance and a compact structure. To address this technical problem, this application proposes a surveying and setting-out device for urban planning design. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a surveying and setting-out device for urban planning design. This invention achieves rapid positioning and assembly of the equipment through component cooperation, improving installation efficiency, while the support legs enhance stability. The operation buttons allow the dust cover to unfold to form a protective structure or close to prevent dust, ensuring instrument performance. All components operate smoothly in conjunction, and the compact structure facilitates use.

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

[0006] A surveying and setting-out device for urban planning design includes a base plate and a body. A support column is fixedly connected to the outside of the base plate. A limit block is installed inside the support column. A second spring is fixedly connected to the bottom of the limit block. A button is installed at the top of the support column. A button two is slidably connected to the outer wall of the button one. A rod one is rotatably connected to the outside of the button one. A rod two is rotatably connected to the bottom of the rod one. A fixing block is fixedly connected to the bottom of the rod two. A dust cover is fixedly connected to the outside of the fixing block. A rotating block is rotatably connected to the outside of the dust cover. A support block is slidably connected inside the button one. A spring one is installed outside the support block. A rotating plate is rotatably connected to the lower part of the body. An adjustment knob is installed at the lower part of the rotating plate. A fixing plate one is fixedly connected to the lower part of the adjustment knob. A fixing plate two is installed below the fixing plate. A groove is formed inside the fixing plate two. A fixing block two is fixedly connected to the lower part of the fixing plate two. A fixing block one is fixedly connected to the lower part of the fixing plate two. A threaded knob is installed on the outside of the fixing block one.

[0007] Furthermore, an observation mirror is provided on the upper part of the machine body, and an alignment knob is provided on the outside of the machine body.

[0008] Furthermore, the support column is fixedly connected to the upper part of the observation mirror.

[0009] Furthermore, the outer walls of the first and second fixing blocks are provided with threaded protrusions, and the inner wall of the threaded knob is provided with threaded grooves.

[0010] Furthermore, a horizontal bubble block is fixedly connected to the top of the fixing plate.

[0011] Furthermore, the support block and spring are disposed on both sides of the support column.

[0012] Furthermore, the rotating block is disposed on the outer wall of the base plate, and the spring is fixedly connected to the top of the base plate.

[0013] Furthermore, the button one is provided with an outer shell, and the bottom of the fixing plate two is rotatably connected with a support leg.

[0014] This utility model has the following beneficial effects:

[0015] 1. In this utility model, the upper and lower parts of the equipment are quickly positioned by aligning and cooperating the grooves 23 of the fixing plate 22 and the first fixing plate 21, and by combining the first fixing block 26 and the second fixing block 28. The equipment is then externally tightened by rotating the threaded knob 24. The operation is simple, allowing for quick assembly of the equipment and improving installation efficiency. The support legs firmly fix the equipment to the ground, enhancing stability during use and making it suitable for various ground environments. Pressing button 2 causes the fixing block 5 and the dust cover 6 to rotate upwards along the rotating plate 7 through the rotational connection of the first rod 3 and the second rod 4, forming a protective structure on all sides. In the unfolded state, the dust cover effectively blocks direct sunlight, preventing strong light from interfering with instrument operation and readings. It also blocks wind and sand, providing a stable working environment for the instrument, protecting its performance from external environmental influences, and extending its service life.

[0016] 2. In this utility model, after use, pressing button 11 releases the limit on button 2 through the linkage of limit block 15 and spring 29. Under the elastic force of spring 13, button 2 returns to its original position and drives the dust cover 6 to rotate downward and close, forming a closed structure. This effectively prevents dust from entering the instrument, reducing wear and contamination of the instrument's precision parts and further improving the instrument's reliability and durability. The sunshade and windproof space formed after the dust cover is unfolded provides users with a more comfortable operating environment, allowing them to focus on instrument operation without being disturbed by sunlight, thus improving work efficiency and accuracy. The various components (such as rods, fixing blocks, springs, etc.) form a stable transmission system through reasonable mechanical connection and linkage design, ensuring the smoothness and reliability of the dust cover's unfolding and closing action. Long-term use is less prone to jamming or malfunction. The overall structure is compact, and the layout of each component is reasonable. While achieving multi-functional protection, it occupies little space, facilitating the transportation, storage, and relocation of the equipment. Attached Figure Description

Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Reference Figures 2-5A support column 14 is fixedly connected to the outside of the base plate 16. A limit block 15 is set inside the support column 14. A spring 29 is fixedly connected to the bottom of the limit block 15. Pressing the spring 29 causes the limit block 15 to move inward. A button 2 is set at the top of the support column 14. A button 11 is slidably connected to the outer wall of the button 2. Pressing the button 11 causes the limit block 15 to press the spring 29 inward. A rod 3 is rotatably connected to the outside of the button 2. A rod 4 is rotatably connected to the bottom of the rod 3. A fixing block 5 is fixedly connected to the bottom of the rod 4. A dust cover 6 is fixedly connected to the outside of the fixing block 5. A rotating block 17 is rotatably connected to the outside of the dust cover 6. When the rod 3 moves downward, it drives the rod 4 to move. The rod 4 drives the fixing block 5 to move upward, thereby causing the fixing block 5 to drive the entire dust cover 6 to unfold upward, serving as a wind and sun shield. A support block 12 is slidably connected inside the button 2. An external spring 13 is provided, which can push button 2 to move upward, thereby causing rod 3 and rod 4 to close downward with the dust cover 6, thus providing a dust cover function. A rotating plate 7 is rotatably connected to the lower part of the body 20. An adjustment knob 8 is provided at the lower part of the rotating plate 7 to facilitate adjustment of the rotation angle. A fixing plate 21 is fixedly connected to the lower part of the adjustment knob 8. A fixing plate 22 is provided at the lower part of the fixing plate 21. A groove 23 is opened inside the fixing plate 22. The fixing plate 21 can quickly engage with the fixing plate 22 along the groove 23. A fixing block 28 is fixedly connected to the lower part of the fixing plate 21. A fixing block 26 is fixedly connected to the lower part of the fixing plate 22. A threaded knob 24 is provided on the outside of the fixing block 26. By engaging the fixing block 26 and the fixing block 28, and then rotating the threaded knob 24, the engagement of the fixing plate 21 and the fixing plate 22 is made more secure.

[0026] Reference Figures 1-5 An observation mirror 18 is provided on the upper part of the body 20, and an alignment knob 19 is provided on the outside of the body 20, allowing the user to observe and adjust simultaneously. A support column 14 is fixedly connected to the upper part of the observation mirror 18 for more secure support. Threaded protrusions 27 are provided on the outer walls of fixing blocks 1 26 and 28, and threaded grooves 25 are provided on the inner wall of the threaded knob 24. The threaded knob 24 can be used to fix fixing blocks 1 26 and 28 by rotation, requiring no tools and can be tightened manually, saving time. The top of the fixing plate 1 21... A horizontal bubble block 9 is fixedly connected to the part to adjust the flatness of the equipment. The support block 12 and spring 13 are set on both sides of the support column 14. The springs on both sides make the button 2 return to its position more smoothly and prevent jamming. The rotating block 17 is set on the outer wall of the base plate 16, so that the dust cover 6 rotates up and down along the rotating block 17 to achieve the effect of opening and closing. The spring 13 is fixedly connected to the top of the base plate 16. The fixed connection of the spring to the top of the base plate 16 reinforces its limit and prevents the part from being deformed by pressure.

[0027] Working principle: In use, this utility model aligns the fixing plate 22 with the groove 23 of the fixing plate 21, combines the fixing block 26 with the fixing block 28, then removes the threaded knob 24 and rotates it outside the fixing blocks 26 and 28 to tighten them, thus combining the upper and lower parts of the equipment into a whole. The support legs are then opened and fixed to the ground. The outer casing 1 is then removed, and button 2 is pressed, causing the rod 3 to move downwards. Then, rod 4, through its rotational connection with rod 3, drives the fixing block 5 and dust cover 6 to rotate and unfold along the rotating plate 7, which is set around the base plate 6. The dust cover 6 will rotate upwards and unfold completely. The rotation and unfolding of the dust cover can provide shade and wind protection, thus protecting the instrument. It also makes the operation smoother for the user, without having to worry about sunlight. After use, by pressing button 11, it pushes the limit block 15 inwards. The limit block 15 retracts inwards through spring 29, causing button 2 to lose its limiting effect. Then, spring 13 pushes button 2 upwards, returning button 2 to its original position. This causes rod 3 to drive rod 4 and fixing block 5 to rotate downwards, causing the dust cover 6 to rotate downwards and be in a closed state, blocking dust and protecting the lifespan of the instrument.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
