[0025] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention.

Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0026] Reference Figure 2 、 Figure 4 and Figure 5 The utility model provides an embodiment of a multifunctional rangefinder, including a support frame 1 and a placement plate 7, wherein both sides of the interior of the placement plate 7 are fixedly connected with slide bars 11, and both sides of the exterior of the two slide bars 11 are slidably connected with sliders 12, and the opposite sides of the multiple sliders 12 are fixedly connected with hinge blocks 14, and the interior of the hinge block 14 is rotatably connected with a movable support rod 15, and the other end of the movable support rod 15 is rotatably connected to the interior of the hinge block 2 16, and the opposite sides of the multiple hinge blocks 2 16 are fixedly connected with splints 17, and the upper parts of the two splints 17 are fixedly connected with mounting plates 18, and the upper part of the mounting plate 18 is fixedly connected with a hydraulic cylinder 19, and the output of the hydraulic cylinder 19 The end is fixedly connected to a pressure plate 22, and both sides of the outside of the slide rod 11 are provided with a return spring 13, one end of the return spring 13 is fixedly connected to the inside of the placement plate 7, and the other end of the return spring 13 is fixedly connected to the slider 12. Both sides of the upper part of the pressure plate 22 are fixedly connected to the limit columns 20, and multiple limit columns 20 are slidably connected to the inside of the mounting plate 18. The outside of the limit column 20 is provided with a compression spring 21, one end of the compression spring 21 is fixedly connected to the bottom of the mounting plate 18, and the other end of the compression spring 21 is fixedly connected to the upper part of the pressure plate 22. A rangefinder body 23 is provided on the opposite side of the two splints 17, and the rangefinder body 23 is provided on the upper part of the placement plate 7.

[0027] First, the rangefinder body 23 needs to be accurately placed on the upper part of the placement plate 7. In order to ensure its stability, it is placed between the two clamping plates 17. In this way, when the clamping plates 17 are squeezed, they will transmit force through the movement of the hinge block 2 16. This hinge block 2 16 is connected to the hinge block 1 14 through the movable support rod 15. Therefore, when the hinge block 2 16 moves, the hinge block 14 will also move with it. Next, the slider 12 slides to both sides outside the slide bar 11, squeezing the reset spring 13, which is an elastic element When squeezed, elastic deformation will occur. When the rangefinder body 23 is placed between the two clamping plates 17, the return spring 13 will drive the two clamping plates 17 closer together under the elastic action, thereby fixing the rangefinder body 23 on the upper part of the placement plate 7. At the same time, we start the hydraulic cylinder 19 and push the pressure plate 22 downward through its output end. During this process, the pressure plate 22 will drive the limit column 20 to slide inside the mounting plate 18. The movement of the pressure plate 22 stretches the compression spring 21, so that under the action of the pressure plate 22, the rangefinder body 23 is fixed again.

[0028] Reference Figure 1 、 Figure 3 and Figure 6 The upper part of the support frame 1 is fixedly connected to the support plate 2, the inside of the support plate 2 is fixedly connected to the motor 3, the output end of the motor 3 is fixedly connected to the worm 4, the front part of the worm 4 is meshed with the worm gear 5, the inside of the worm gear 5 is fixedly connected to the rotating rod 6, the upper part of the rotating rod 6 is fixedly connected to the placement plate 7, the bottom of the placement plate 7 is fixedly connected to the limiting component, the limiting component is used to limit the placement plate 7, the limiting component includes a support rod 8, multiple support rods 8 are fixedly connected to the bottom of the placement plate 7, the bottom of the support rod 8 is fixedly connected to the limiting block 9, a limiting slot 10 is provided inside the support plate 2, and the limiting block 9 is slidably connected to the inside of the limiting slot 10.

[0029] When the viewing angle of the rangefinder body 23 needs to be adjusted, the drive motor 3 needs to be started first. When the motor 3 starts working, its output end will drive the worm 4 to rotate, and the rotation of the worm 4 will be transmitted to the worm gear 5, thereby causing the worm gear 5 to start rotating. The rotation of the worm gear 5 will drive the rotating rod 6 to rotate, and the rotation of the rotating rod 6 will cause the placement plate 7 to rotate. When the placement plate 7 rotates, it will drive the support rod 8 and the limit block 9 to rotate together, and the limit block 9 will slide inside the limit slot 10. In this way, the placement plate 7 can drive the rangefinder body 23 to rotate, thereby adjusting the angle of the rangefinder body 23.

[0030] Working principle: First, place the rangefinder body 23 on the upper part of the placement plate 7 and between the two clamping plates 17. The clamping plate 17 is squeezed to drive the hinge block 2 16 to move. The movement of the hinge block 2 16 drives the hinge block 1 14 connected by the movable support rod 15 to move. The hinge block 14 drives the slider 12 to move. The slider 12 slides to both sides outside the slide bar 11, squeezing the reset spring 13. The reset spring 13 is squeezed and elastically deformed. When the rangefinder body 23 is placed between the two clamping plates 17, the two clamping plates 17 are driven close to each other under the elastic action of the reset spring 13, and the rangefinder body 23 is fixed to the upper part of the placement plate 7. At the same time, the hydraulic cylinder 19 is started, and the output end of the hydraulic cylinder 19 pushes the pressure plate 22 to move downward. When the pressure plate 22 moves, it drives the limit column 20 to slide inside the mounting plate 18. The pressure plate 22 moves to stretch the compression spring 21. Under the action of the pressure plate 22, the rangefinder body 23 is The rangefinder body 23 is fixed again, and the rangefinder body 23 can be fixed on the upper part of the placement plate 7, which effectively clamps and fixes the rangefinder body 23, ensures that the rangefinder is firmly fixed in a certain position during measurement, avoids inaccurate measurement due to hand shaking or other external factors, and improves the accuracy of the measurement work. When the angle of the rangefinder body 23 needs to be adjusted, the motor 3 is started, and the output end of the motor 3 drives the worm 4 to rotate, the worm 4 drives the worm gear 5 to rotate, the worm gear 5 drives the rotating rod 6 to rotate, and the rotating rod 6 drives the placement plate 7 to rotate. When the placement plate 7 rotates, it drives the support rod 8 and the limit block 9 to rotate, so that the limit block 9 slides inside the limit groove 10, so that the placement plate 7 drives the rangefinder body 23 to rotate, thereby facilitating the adjustment of the angle of the rangefinder body 23, facilitating measurement from multiple angles, better adapting to the environment, performing effective measurement, and improving the flexibility of measurement.
