Description

Technical Field

[0001] This utility model belongs to the field of engineering surveying and mapping technology, and in particular relates to a positioning device for a surveying instrument. Background Technology

[0002] Engineering surveying is a professional activity that applies surveying principles and techniques to provide accurate geospatial information for various engineering projects. It runs through all stages of engineering project planning, design, construction, operation and maintenance, aiming to ensure that the project can be implemented smoothly in accordance with predetermined design specifications and safety standards.

[0003] Existing surveying instruments lack an easy-to-install positioning device. The problem with the aforementioned technology is that existing surveying instruments often lack a convenient and efficient positioning device in practical applications. This leads to low efficiency and complex operation during installation and disassembly. Traditional installation methods usually require a lot of time, manpower, and resources, which not only increases the difficulty of the work but may also affect the accuracy of measurement results due to insecure installation. Due to the lack of a specially designed positioning device, surveyors often encounter various challenges when placing equipment in different environments, such as uneven terrain and difficulty in selecting fixed points. These problems directly affect work efficiency and data quality. Utility Model Content

In addition, the presence of the telescopic rod enhances the response speed and sensitivity of the mechanism, solving the problem that existing surveying instruments often lack a convenient and efficient positioning device in practical applications.

A fixing mechanism 1 is provided at the lower end of the surveying instrument 7, and an auxiliary mechanism 2 is provided on the fixing mechanism 1. The fixing mechanism 1 is used to install the surveying instrument 7, and the auxiliary mechanism 2 is used to assist the installation process. The fixing mechanism 1 includes a locking block 101, a receiving block 102, a fixing plate 103, a connecting block 104, a double-ended screw 105, a limiting plate 106, and a bearing bracket 107.

The upper end of the 03 is fixedly connected to the lower end of the connecting block 104. The inner walls of the two connecting blocks 104 are threadedly connected to the two ends of the double-ended screw 105. The middle surface of the double-ended screw 105 is fixedly connected to the inner wall of the limiting plate 106. The surface of the limiting plate 106 is rotatably connected to the inner wall of the bearing bracket 107 through a sliding groove. The limiting plate 106 not only ensures the stability of the double-ended screw 105 during rotation, but also restricts its axial displacement, increasing the reliability of the double-ended screw 105 during operation. The auxiliary mechanism 2 includes a mounting base 201, a guide groove 202, a stroke plate 203, a telescopic rod 204, a spring 205, and a support block 206. The guide groove 202 is opened on both sides of the lower end of the mounting base 201. The inner wall of the guide groove 202 is slidably connected to the surface of the stroke plate 203. The two stroke plates 203 are slidably connected to the inner wall of the guide groove 202. The wall is fixedly connected to both ends of the telescopic rod 204, and both ends of the telescopic rod 204 are fixedly connected to both ends of the spring 205. The surface of the spring 205 is fixedly connected to the inner wall of the support block 206. The function of the telescopic rod 204 is to further ensure the consistency of the movement of the two side locking blocks 101 and avoid the problem of misalignment of the locking blocks 101 due to uneven force on one side. In addition, the presence of the telescopic rod 204 enhances the response speed and sensitivity of the mechanism. A stroke groove 3 is opened on the lower side of the middle of the mounting base 201. Fixed rods 4 are provided on both sides of the upper end of the fixed base 6. The lower surface of the fixed rod 4 is fixedly connected to the upper side surfaces of the fixed base 6. The stroke groove 3 provides an operating guide for the receiving block 102, ensuring its accuracy and consistency when moving laterally, making the installation and disassembly process faster. The design is simple. The surface of the locking block 101 slides in contact with the inner wall of the fixed base 6, the surface of the receiving block 102 slides in connection with the inner wall of the travel groove 3, the lower surface of the fixed plate 103 slides in connection with the inner wall of the mounting base 201, the two ends of the double-ended screw 105 are rotatably connected to the inner wall of the mounting base 201, the lower surface of the bearing bracket 107 is fixedly connected to the inner wall of the mounting base 201, and the surface of the locking block 101 contacts the lower surface of the fixed rod 4. By utilizing the oppositely oriented threads at both ends of the double-ended screw 105, rotating the double-ended screw 105 can drive the connecting block 104 to move along a predetermined trajectory, thereby achieving effective fixing or quick disassembly of the surveying instrument 7. The lower surface of the mounting base 201 contacts the upper surface of the fixed base 6, and the lower surface of the travel plate 203 is fixedly connected to the upper two sides of the locking block 101.The surface of the support block 206 is fixedly connected to the inner wall of the guide groove 202. The stroke plate 203 ensures the stability of the locking block 101 during lateral movement, preventing unnecessary offset or shaking of the locking block 101 during operation, thus ensuring its accuracy when in contact with the fixed rod 4. The upper surface of the mounting base 201 is fixedly connected to the lower surface of the surveying instrument 7. By fixing the mounting base 201 to the surveying instrument 7, the surveying instrument 7 remains stable throughout the entire operation, thereby resisting the influence of external factors on the instrument and reducing unnecessary displacement or vibration.

[0024] The working principle of this utility model:

[0025] When installing the surveying instrument 7, the first step is to place the mounting base 201 at the bottom of the surveying instrument 7 onto the pre-set surface of the fixing base 6 on the adjusting bracket 5. Aligning the mounting base 201 with the fixing base 6 ensures the surveying instrument 7 is securely placed. Next, the operator rotates the double-ended screw 105 installed in the mounting base 201. The double-ended screw 105 has threads in opposite directions at both ends. When the operator rotates the double-ended screw 105, the connecting block 104 on it moves along a predetermined trajectory driven by the threads, causing the connected receiving block 102 to slide smoothly within the travel groove 3. A locking block 101 is fitted below the receiving block 102. During this process, the locking block 101 moves outwards along the inner wall of the fixing base 6 as the receiving block 102 moves. The measuring instrument 7 is moved laterally until the locking block 101 is in close contact with the fixing rod 4, thereby effectively fixing the measuring instrument 7. During this process, the travel plates 203 equipped on both sides of the upper end of the locking block 101 also slide synchronously in the guide groove 202, ensuring the stability and accuracy of the locking block 101 during lateral movement. At the same time, the telescopic rod 204 further ensures the consistency of the movement of the locking blocks 101 on both sides, enhancing the reliability of the entire fixing mechanism 1. After fixing is completed, the user can adjust the height of the bracket 5 to make the measuring instrument 7 reach the optimal use position to meet different measurement needs. When it is necessary to disassemble the measuring instrument 7, simply rotate the double-headed screw 105 in the opposite direction to make the locking block 101 smoothly exit from the fixing rod 4, and the measuring instrument 7 can be easily removed as a whole, realizing a fast and non-destructive disassembly process.
