Description

Technical Field

[0001] The utility model relates to the field of surveying and mapping, and more specifically, to a novel surveying and mapping layout device. Background Art

[0002] Surveying and mapping layout equipment is simply a data collection, processing, output and other instruments and devices designed and manufactured for surveying and mapping operations. Various instruments for orientation, distance measurement, angle measurement, height measurement, mapping and photogrammetry are required for surveying work during the planning, design, construction and management stages of engineering construction.

[0003] The Chinese patent authorization announcement number: CN211148955U provides a civil engineering measurement and layout device, which includes a theodolite body; a tripod bracket, which is arranged below the theodolite body; a mounting base, which is fixedly mounted on the top of the tripod bracket; a placement groove, which is arranged on the top of the mounting base; a connecting seat, which is fixedly mounted on the bottom of the theodolite body and is located in the placement groove; a first card slot, which is arranged at the bottom of the connecting seat; a limiting block, which is fixedly mounted on the bottom inner wall of the placement groove, and the top of the limiting block extends into the first card slot; a surface groove, which is arranged on the top of the mounting base and is connected to the placement groove.

[0004] However, in the above patent, when using the surveying instrument to survey the surrounding environment, the lower end of the support foot used in the existing surveying instrument is relatively sharp. When the support foot is placed on soft soil, due to the small area of ​​the lower end of the support foot, the pressure between the lower end of the support foot and the ground is relatively large, making it easy for the support foot to sink into the ground due to gravity, thereby causing the surveying instrument to easily deflect on the soft soil ground, resulting in inaccurate measurement.

[0005] Therefore, a new type of surveying and mapping layout device is proposed to solve the above problems. Utility Model Content

[0029] Example:

[0030] See also Figure 1-4A novel surveying and mapping layout device includes a base 1, a telescopic rod 11 is rotatably connected to the bottom of the base 1, a mounting sleeve 14 is fixedly connected to the lower end of the telescopic rod 11, a plug-in rod 21 is slidably connected to the inside of the mounting sleeve 14, a limiting groove 22 is provided on the outer wall of the plug-in rod 21, a sphere 23 is fixedly connected to the end of the plug-in rod 21 away from the telescopic rod 11, a sleeve 24 is rotatably connected to the outer wall of the sphere 23, and a positioning cone 25 is fixedly connected to the outside of the sleeve 24. In this solution, if the device needs to be placed on the ground and the soil is relatively soft, the user can rotate the sleeve 24 and make the three sleeves 24 fit the ground. In addition, since the three plug-in rods 21 are rotated through the sphere 23 and the sleeve 24, the three telescopic rods 11 and the ground can be kept relatively stable.

[0031] See also Figure 1-4 The mounting sleeve 14 is internally slidably connected with a sliding block 15, one end of the sliding block 15 is fixedly connected with an arc block 16, and the other end of the sliding block 15 is fixedly connected with a limit block 17. In this solution, the sliding block 15 slides inside the mounting sleeve 14, so that the arc block 16 and the limit block 17 can slide inside the mounting sleeve 14. In addition, chamfers are provided on both sides of the limit block 17.

[0032] See also Figure 1-4 The outer wall of the sliding block 15 is sleeved with a No. 1 spring 18, and the No. 1 spring 18 is located between the arc block 16 and the mounting sleeve 14. The limit block 17 is clamped in the inside of the limit groove 22. In this solution, when the sliding block 15 slides along the outside of the mounting sleeve 14, when the side where the limit block 17 and the sliding block 15 are connected is in contact with the mounting sleeve 14, the arc block 16 is located outside the mounting sleeve 14. When the sliding block 15 slides toward the inside of the mounting sleeve 14, the arc block 16 will squeeze the No. 1 spring 18 and cause the No. 1 spring 18 to undergo elastic deformation and contraction.

[0033] See also Figure 1-4 The outer wall of the mounting sleeve 14 is slidably connected with a blocking plate 19, and a No. 2 spring 2 is arranged inside the blocking plate 19, and the No. 2 spring 2 is sleeved on the outer wall of the mounting sleeve 14. In this scheme, when the blocking plate 19 is in the reset state, the arc block 16 will be blocked inside the mounting sleeve 14, so that the sliding block 15 cannot slide along the direction of the outside of the mounting sleeve 14, thereby ensuring that the limit block 17 is always stuck in the inside of the limit groove 22. If it is necessary to release the limit of the arc block 16 by the blocking plate 19, the blocking plate 19 can be moved to make the blocking plate 19 slide in the direction of the sphere 23. In this process, the inside of the blocking plate 19 will squeeze the No. 2 spring 2 and cause the No. 2 spring 2 to undergo elastic deformation and contraction.

[0034] See also Figure 1-4The outer walls of the three telescopic rods 11 are rotatably connected with a connecting rod 12, the bottom end of the base 1 is fixedly connected with a fixed rod 13, and one end of the three connecting rods 12 is rotatably connected with a slider sliding on the fixed rod 13. In this solution, the three telescopic rods 11 can be rotated synchronously through the connection between the telescopic rod 11, the connecting rod 12 and the fixed rod 13.

[0035] See also Figure 1-4 A surveying instrument 26 is installed above the base 1. In this solution, the surveying instrument 26 is used to survey the surrounding environment.

[0036] Working principle: If the device needs to be placed on the ground which is relatively soft, the user can rotate the sleeve 24 and make the three sleeves 24 fit with the ground. In addition, since the three connecting rods 21 are rotated through the sphere 23 and the sleeve 24, the three telescopic rods 11 and the ground can be kept relatively stable. Then, it is only necessary to use the surveying instrument 26 to survey the surrounding environment. If the user needs to separate the connecting rod 21 and the telescopic rod 11, the user can move the blocking plate 19 to make the blocking plate 19 slide along the direction of the sphere 23. During this process, the inside of the blocking plate 19 will squeeze the No. 2 spring 2 and make the No. 2 spring 2 elastically deform and shrink. At this time, the blocking plate 19 can release the limit on the arc block 16, and then it is in a The compressed No. 1 spring 18 will reset, causing the limit block 17 to lose its engagement with the limit groove 22. The user then only needs to hold the plug rod 21 and pull it out from the inside of the mounting sleeve 14. Similarly, to complete the installation between the plug rod 21 and the mounting sleeve 14, the blocking plate 19 is also first moved in the direction of the sphere 23, and then the plug rod 21 is inserted into the inside of the mounting sleeve 14. When the blocking plate 19 is released and the blocking plate 19 is reset, the arc block 16 will be squeezed. After being squeezed, the arc block 16 will drive the sliding block 15 to slide along the direction of the inside of the mounting sleeve 14, and finally be engaged with the inside of the limit groove 22. At this time, the installation between the plug rod 21 and the mounting sleeve 14 is completed.

[0037] The above is only a preferred specific implementation of the utility model; however, the protection scope of the utility model is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes according to the technical solution and improved ideas of the utility model within the technical scope disclosed by the utility model, which should be included in the protection scope of the utility model.
