Description
Technical Field
[0001] This utility model relates to the field of surveying equipment technology, specifically a fixed bracket for surveying instruments. Background Technology
[0002] Engineering surveying is a crucial step in the design, construction, and management of architectural projects, and its quality directly impacts the safety, practicality, and aesthetics of buildings. Engineering surveying primarily utilizes various measuring equipment and techniques to collect, process, and analyze data on topography, geology, and hydrology to determine parameters such as the location, shape, size, and height of buildings. This provides fundamental data and reference for the design, construction, and management of architectural projects. Engineering surveying requires the use of a surveying instrument. To use the instrument, the support frame is unfolded and fixed to the ground, and then the surveying instrument is secured to the support frame to begin surveying work.
[0003] A search revealed a prior art device for fixing a surveying instrument support (publication number: CN221034768U). This device discloses a support block fixedly mounted on the support, an adjusting plate slidably connected below the support block, several guide posts fixed on the support block, and positioning components slidably connected to the guide posts. The positioning components are inserted into the support posts of the support and fix them in place. A first elastic element is fitted onto the guide post, one end of which is fixedly connected to the positioning component, and the other end is fixedly connected to the support block. Several adjusting posts are fixed on the adjusting plate. While this patent effectively fixes the support posts and ensures stability when the support posts are closed by using positioning components, when the support posts are placed on the ground, their lower ends are tightly pressed against the ground, making it difficult to expand or retract them smoothly. This forces surveyors to lift the device for adjustment, increasing their workload and potentially causing the surveying instrument to shake, thus affecting the accuracy of the surveying results.

[0006] As a further optimization, the sliding assembly includes a fixed base, which is fixedly installed at the lower end of the telescopic rod. A slider is rotatably mounted at the lower end of the fixed base, and a track plate is mounted on the slider. A sliding groove is formed in the track plate, and the lower end of the slider is located in the sliding groove.
[0007] As a further optimization, the number of multiple sets of track plates is the same as the number of multiple sets of telescopic rods, and the multiple sets of track plates extend outward from the center point of the main body of the device and are distributed in a regular triangular shape.
[0008] As a further optimization, the openings at the connection points of the multiple sets of sliders and the multiple sets of fixed seats are arranged in opposite directions, and the upper ends of the multiple sets of sliders are fitted against the inner wall of the connection point of the fixed seats on opposite sides.
[0009] As a further optimization, guide rods are fixedly installed in each of the multiple sets of sliding grooves, and the multiple sets of sliders are slidably sleeved on the multiple sets of guide rods.
[0010] As a further optimization, the cross-section of one end of the multiple sets of sliders located in the multiple sets of sliding grooves is circular, and the cross-section of the inner wall of the multiple sets of sliding grooves is T-shaped.

[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. 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.
[0021] like Figures 1 to 5As shown, a surveying instrument mounting bracket includes a main body 1. A top mounting base 2 is installed on the upper end of the main body 1, and a control handle 3 is installed on the top mounting base 2. A central shaft 4 is fixedly installed on the lower side of the main body 1. A rotating sleeve 5 is sleeved on the central shaft 4. The upper end of the rotating sleeve 5 is rotatably connected to the main body 1. A fixed handle 6 is fixedly installed on the lower end of the rotating sleeve 5. A threaded collar 7 is threadedly connected to the rotating sleeve 5. Multiple sets of connecting rods 8 are rotatably installed on the threaded collar 7. Multiple sets of movable support rods 9 are rotatably installed on the lower side of the main body 1. A telescopic rod 10 is movably inserted into each set of movable support rods 9. A fixed sleeve 11 is fixedly installed at the lower end of each set of movable support rods 9. The lower ends of the multiple sets of connecting rods 8 are rotatably connected to the multiple sets of fixed sleeves 11. A sliding component is provided at the lower end of each set of telescopic rods 10.
[0022] In use, by rotating the rotating sleeve 5 and the fixed handle 6, the threaded collar 7 is driven to move threadedly on the rotating sleeve 5, thereby sliding multiple sets of connecting rods 8, multiple sets of movable support rods 9, and multiple sets of telescopic rods 10 on multiple sets of sliding components. This allows the multiple sets of movable support rods 9 and multiple sets of telescopic rods 10 to be expanded or retracted. The sliding components not only enhance the stability of the multiple sets of movable support rods 9 and multiple sets of telescopic rods 10, but also make the expansion and retraction operations of the multiple sets of movable support rods 9 and multiple sets of telescopic rods 10 on the ground more convenient, reducing the workload of surveyors.
[0023] The sliding assembly includes a fixed base 13, which is fixedly installed at the lower end of the telescopic rod 10. A slider 14 is rotatably installed at the lower end of the fixed base 13. A track plate 15 is installed on the slider 14. A sliding groove 16 is provided in the track plate 15. The lower end of the slider 14 is located in the sliding groove 16.
[0024] In use, by sliding the slider 14 in the sliding groove 16, the angles of the multiple sets of connecting rods 8, multiple sets of movable support rods 9 and multiple sets of telescopic rods 10 are adjusted when placed on the ground, making the expansion and retraction of the multiple sets of movable support rods 9 and multiple sets of telescopic rods 10 on the ground more convenient.
[0025] The number of multiple sets of track plates 15 is the same as the number of multiple sets of telescopic rods 10. The multiple sets of track plates 15 extend outward from the center point of the main body 1 of the device and are distributed in a regular triangular shape.
[0026] This triangular distribution design not only enhances the stability of the entire device, but also allows the device to be subjected to force more evenly when expanding or retracting, avoiding deformation or damage caused by uneven force distribution.
[0027] The openings at the connection points of the multiple sets of sliders 14 and the multiple sets of fixed seats 13 are arranged in opposite directions, and the upper ends of the multiple sets of sliders 14 are in contact with the inner wall of the connection point of the fixed seats 13.
[0028] Based on the connection method and position of the multiple sets of sliders 14 and the multiple sets of fixed seats 13, the multiple sets of sliders 14 rotate on the multiple sets of fixed seats 13 to the opposite side of the multiple sets of telescopic rods 10, thereby bringing the upper side of the multiple sets of track plates 15 into contact with the opposite side of the multiple sets of telescopic rods 10.
[0029] Guide rods 17 are fixedly installed in multiple sets of sliding grooves 16, and multiple sets of sliders 14 are slidably sleeved on multiple sets of guide rods 17.
[0030] The arrangement of multiple guide rods 17 not only provides guidance for the sliding of the slider 14, but also enhances the stability of the slider 14 in the sliding groove 16, preventing the slider 14 from shaking or falling off during the sliding process.
[0031] The cross-section of one end of the multiple sets of sliders 14 located within the multiple sets of sliding grooves 16 is circular, and the cross-section of the inner wall of the multiple sets of sliding grooves 16 is T-shaped.
[0032] This combination of circular and T-shaped design allows the slider 14 to slide smoothly within the sliding groove 16 while ensuring the stability of the sliding, thus avoiding operational difficulties or device damage caused by poor sliding.
[0033] Each of the multiple sets of fixed sleeves 11 has a fixed rod 12 fixedly installed on the opposite side. Each of the multiple sets of sliding grooves 16 has a first side plate 18 fixedly installed on the upper side. Each of the multiple sets of first side plates 18 has a positioning plate 19 rotatably installed on the upper end. Each of the multiple sets of sliding grooves 16 has a second side plate 20 fixedly installed on the upper side. Each of the multiple sets of positioning plates 19 has a retainer 21 fixedly installed on the upper side.
[0034] In use, the clip 21 engages with the fixing rod 12 on the fixing sleeve 11, thereby allowing the track plate 15 to rotate and retract, thus fitting and fixing it to the telescopic rod 10.
[0035] Multiple sets of sharp anti-slip nails are provided on the underside of the multiple sets of track plates 15.
[0036] The installation of these anti-slip studs not only enhances the friction between the track plate 15 and the ground, preventing the device from sliding or shifting during use, but also helps to better fix the device to the ground when it is expanded or retracted, further ensuring the stability and safety of the surveying work.
[0037] In use, surveyors first place the device on the ground. By rotating the rotating sleeve 5 and the fixed handle 6, and since the rotating sleeve 5 and the threaded collar 7 are threadedly connected, rotating the rotating sleeve 5 can drive the threaded collar 7 to move up and down on the rotating sleeve 5. At the same time, multiple sets of connecting rods 8 are rotatably mounted on the threaded collar 7. The lower ends of the multiple sets of connecting rods 8 are rotatably connected to multiple sets of fixed sleeves 11. The multiple sets of fixed sleeves 11 are fixedly connected to multiple sets of movable support rods 9. Therefore, when the threaded collar 7 moves on the rotating sleeve 5, it can drive the multiple sets of connecting rods 8 and the threaded collar 7 to move up and down on the rotating sleeve 5. The movable support rod 9 and multiple sets of telescopic rods 10 are unfolded. When the multiple sets of telescopic rods 10 are unfolded, they slide in multiple sets of sliding grooves 16 on multiple sets of track plates 15 through the fixed seat 13 and multiple sets of sliders 14. This allows the multiple sets of movable support rods 9 and multiple sets of telescopic rods 10 to be expanded or retracted when placed on the ground. The positioning plate 19 is rotated on the first side plate 18 and fixed to the upper side of the second side plate 20. This allows the sleeve 21 on the upper side of the positioning plate 19 to engage with the fixing rod 12 on the fixed sleeve 11, so that the track plate 15 can be fitted and fixed to the telescopic rods 10 when it is rotated and retracted.
[0038] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
