Abstract
Description
Technical Field
[0001] This utility model relates to the field of laser rangefinder technology, specifically to a multi-scenario laser rangefinder angle adjustment bracket. Background Technology
[0002] A laser rangefinder is an instrument that uses lasers to measure distance. It works by emitting a very short laser pulse onto a target surface and then measuring the time it takes for the pulse to travel from emission to reception to calculate the distance. Since the speed of light is known, a fairly accurate distance can be obtained by precisely measuring the time difference.
[0003] When using a laser rangefinder, the detection angle needs to be adjusted according to the usage scenario. When placing and installing the laser rangefinder, a mounting bracket is needed to fix the rangefinder in place. However, if a collision occurs after the mounting bracket is installed, it can easily affect the detection position of the rangefinder, thereby affecting the normal distance sampling of the rangefinder. To address this, we propose a multi-scenario laser rangefinder angle adjustment bracket. Utility Model Content

Detailed Implementation
[0017] 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.
[0018] Please see Figures 1-4 This utility model provides a technical solution: a multi-scene laser rangefinder angle adjustment bracket, including a fixed frame 1 and a rangefinder body 6. A mounting plate 4 is fixedly installed on the top of the fixed frame 1. An angle adjustment mechanism 5 for multi-angle adjustment of the rangefinder body 6 is provided on one side of the mounting plate 4. Multiple sets of fixing mechanisms 2 for supporting the fixed frame 1 and the rangefinder body 6 are rotatably connected to the outside of the fixed frame 1. A support positioning mechanism 3 for secondary positioning of the fixed frame 1 is fixedly installed at the bottom of the fixed frame 1. A secondary reinforcement mechanism 7 for preventing the fixed mechanism 2 from shifting position is provided on the outside of the support positioning mechanism 3.
[0019] The angle adjustment mechanism 5 can adjust the detection angle of the rangefinder body 6, while the fixing mechanism 2 can install and fix the fixing frame 1 and the rangefinder body 6 according to the required height. The support and positioning mechanism 3 can support the bottom of the fixing frame 1, thereby preventing the fixing frame 1 and the rangefinder body 6 from shifting position. After the fixing mechanism 2 is installed, the secondary reinforcement mechanism 7 can support the fixing mechanism 2, thereby preventing the fixing mechanism 2 from shifting due to external force collision.
[0020] Please see Figure 1 , Figure 2 and Figure 3 The fixing mechanism 2 includes a hinge seat 8, a first limiting rod 9, a slide seat 10, a slide rod 11, a fixing seat 12, and a locking screw 13. Multiple sets of hinge seats 8 are rotatably connected to the fixing frame 1. One end of the hinge seat 8 is fixedly connected to the slide seat 10 through two sets of first limiting rods 9. The slide rod 11 is slidably connected inside the slide seat 10. One end of the slide rod 11 is fixedly connected to the fixing seat 12. The sliding seat 10 is threaded with a locking screw 13 that contacts the outside of the slide rod 11. Semi-circular grooves that fit against the outer wall of the first limiting rod 9 are opened on both sides of the slide rod 11.
[0021] When it is necessary to use the fixing mechanism 2 to fix the rangefinder body 6, unscrew the locking screw 13, pull the slide rod 11 to move along the slide base 10, and then use the locking screw 13 to fix the slide rod 11. Once the fixing is completed, the rangefinder body 6 can be fixed. When the slide rod 11 moves, the semi-circular groove can move along the first limit rod 9, thereby preventing the slide rod 11 from shifting position.
[0022] Please see Figure 1 , Figure 2 and Figure 3 The support and positioning mechanism 3 includes a hollow tube 14, a telescopic rod 15, a first fixing plate 16, a second fixing plate 17, and a spring 19. The hollow tube 14 is installed at the bottom of the fixing frame 1. The telescopic rod 15 is slidably connected inside the hollow tube 14. The first fixing plate 16 and the second fixing plate 17 are respectively fixedly connected to the outside of the hollow tube 14 and the telescopic rod 15. Multiple sets of second limiting rods 18 are slidably connected on the first fixing plate 16. The bottom of the second limiting rod 18 is fixedly connected to the second fixing plate 17. The spring 19 is fixedly installed on the top of the second fixing plate 17 and outside the second limiting rod 18. The top of the spring 19 is fixedly connected to the first fixing plate 16. An insertion block 20 is inserted into the bottom of the telescopic rod 15. The bottom of the insertion block 20 is fixedly connected to the first support plate 21.
[0023] The spring 19 can push the telescopic rod 15 downward along the hollow tube 14, so that the first support plate 21 can always be in contact with the ground, providing a certain support for the entire device and preventing the rangefinder body 6 from shifting position during use. When the telescopic rod 15 moves up and down, it can be limited by the first fixing plate 16, the second fixing plate 17, and the second limiting rod 18 to prevent the telescopic rod 15 from shifting position. Furthermore, the first support plate 21 and the insertion block 20 are detachable, making them easier to disassemble during transfer.
[0024] Please see Figure 1 , Figure 2 and Figure 3 The secondary reinforcement mechanism 7 includes an external threaded groove 22, a first threaded sleeve 23, an mounting rod 24, and a second support plate 25. The hollow tube 14 has an external threaded groove 22 on its outside. The external threaded groove 22 is connected to the first threaded sleeve 23. The top of the first threaded sleeve 23 is fixedly connected to two sets of mounting rods 24. A semi-circular second support plate 25 that contacts the inner wall of the fixing mechanism 2 is inserted into the mounting rod 24.
[0025] After the fixing mechanism 2 is installed, the corresponding semi-circular second support plate 25 is inserted into the outside of the mounting rod 24. Then, according to the bending angle of the fixing mechanism 2, the first threaded sleeve 23 is rotated to move upward along the external thread groove 22. This allows the second support plate 25 to contact the inner wall of the fixing mechanism 2, thereby preventing the fixing mechanism 2 from shifting due to external force collision.
[0026] Please see Figure 1 and Figure 4 The angle adjustment mechanism 5 includes a first connecting rod 26, a universal sleeve 27, a universal ball 28, a second threaded sleeve 29, and a threaded rod 30. One side of the mounting plate 4 is fixedly connected to the universal sleeve 27 via the first connecting rod 26. The universal ball 28 is rotatably connected inside the universal sleeve 27. One side of the universal ball 28 is fixedly connected to the rangefinder body 6 via the second connecting rod 31. The second threaded sleeve 29 is fixedly installed on the top of the universal sleeve 27. The threaded rod 30, which contacts the outside of the universal ball 28, is threadedly connected inside the second threaded sleeve 29.
[0027] When the angle of the rangefinder body 6 needs to be adjusted, unscrew the threaded rod 30 to allow the universal ball 28 to rotate along the inside of the universal sleeve 27, thereby adjusting the rangefinder body 6 to the required angle. After the angle adjustment is completed, tighten the threaded rod 30 to make the threaded rod 30 contact and fix it to the outside of the universal ball 28, thus completing the position adjustment of the rangefinder body 6.
[0028] In use, firstly, the angle adjustment mechanism 5 adjusts the detection angle of the rangefinder body 6. The fixing mechanism 2 secures the mounting frame 1 and the rangefinder body 6 to the required height. Then, the support and positioning mechanism 3 supports the bottom of the mounting frame 1, preventing positional shifts between the mounting frame 1 and the rangefinder body 6. After the fixing mechanism 2 is installed, the secondary reinforcement mechanism 7 further supports it, preventing shifts caused by external impacts. When the fixing mechanism 2 fixes the rangefinder body 6, the locking screw 13 is unscrewed, and the slide rod 11 is pulled to move along the slide base 10. Then, the locking screw 13 can be used to fix the slide rod 11. Once the fixing is complete, the rangefinder body 6 can be fixed. When the slide rod 11 moves, the semi-circular groove can move along the first limit rod 9, thereby preventing the slide rod 11 from shifting position. The spring 19 can push the telescopic rod 15 to move downward along the hollow tube 14, so that the first support plate 21 can always be in contact with the ground. The first support plate 16, the second support plate 17, and the second limiting rod 18 can be used to limit the movement of the telescopic rod 15 during use, preventing it from shifting position. The first support plate 21 and the insertion block 20 are designed to be detachable, facilitating easier assembly and disassembly during transport. After the fixing mechanism 2 is installed, the corresponding semi-circular second support plate 25 is inserted into the outside of the mounting rod 24, and then adjusted according to the bending angle of the fixing mechanism 2. Rotate the first threaded sleeve 23 to move it upward along the external thread groove 22, so that the second support plate 25 can contact the inner wall of the fixing mechanism 2, thereby preventing the fixing mechanism 2 from being displaced due to external force collision. When it is necessary to adjust the angle of the rangefinder body 6, unscrew the threaded rod 30 to make the universal ball 28 rotate along the inside of the universal sleeve 27, and adjust the rangefinder body 6 to the required angle. After the angle adjustment is completed, tighten the threaded rod 30 to make the threaded rod 30 contact and fix the universal ball 28 to complete the position adjustment of the rangefinder body 6.
