Description

Technical Field

[0001] This utility model relates to the field of laser rangefinder calibration technology, specifically a reference surface adjustment device for calibrating a handheld laser rangefinder. Background Technology

[0002] A laser rangefinder is an instrument that accurately measures the distance to a target using a modulated laser parameter. The working principle of a laser rangefinder is mainly based on the echo time and speed of light after a laser pulse is reflected from the target object to calculate the distance between the target and the rangefinder. The reference plane plays a crucial role in the use of a laser rangefinder, directly affecting the accuracy and reliability of the measurement results. The reference plane refers to the plane or surface used as a measurement reference during measurement. In the use of a laser rangefinder, the reference plane is usually the reference surface for laser beam emission and reception, used to determine the starting or ending point of the measurement distance. Adjusting the laser rangefinder's reference plane is a key step to ensure measurement accuracy and stability. By selecting a suitable reference plane, setting reference points, adjusting the laser rangefinder, and performing calibration, the accuracy and reliability of the measurement can be effectively improved. At the same time, during use, it is also necessary to pay attention to avoiding interference, maintaining stability, correct operation, and safety precautions.

[0003] However, common reference surface adjustment devices for handheld laser rangefinder calibration are inconvenient to rotate or fine-tune in the vertical direction during use, which leads to inaccurate calibration results and poor adjustment effect.

[0004] Therefore, we propose a reference surface adjustment device for the calibration of a handheld laser rangefinder to solve the problems mentioned above. Utility Model Content

[0030] 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. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. 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. Specific Implementation

[0031] This embodiment is a reference surface adjustment device for calibrating a handheld laser rangefinder.

[0032] like Figure 1 , Figure 3 , Figure 4 , Figure 5 and Figure 6 As shown, base 1 is mounted on the platform and is threadedly connected to one-way threaded rods 2, which are arranged in an array. A sphere is provided on the upper side of each one-way threaded rod 2, and the sphere and spherical hole 5 are rotatable. The one-way threaded rod 2 is rotatably connected to the spherical hole 5, which is located within an ear plate 4. The ear plates 4 are arranged in an array on the side of the support platform 3. The one-way threaded rods 2, ear plates 4, and spherical holes 5 correspond one-to-one, thus connecting base 1 and support platform 3. A connecting shaft is rotatably connected to the upper side of the spherical hole 5. 6. The connecting shaft 6 is meshed with the toothed plate 7. The toothed plate 7 has a slot 8 inside. The toothed plate 7 and the support platform 3 are connected by the slot 8. The toothed plate 7 has a mating hole 9 on its side. The mating holes 9 are arranged in an array. The mating holes 9 are connected to the limiting post 11 by a slot. The limiting post 11 is slidably connected to the connecting plate 10. The connecting plate 10 is fixedly installed on the upper side of the support platform 3. The limiting post 11 is fixedly connected to one end of the spring 12. The other end of the spring 12 is fixedly connected to the connecting plate 10. The spring 12 is located outside the limiting post 11.

[0033] like Figure 1 and Figure 2 As shown, a support plate 13 is provided on the upper side of the connecting shaft 6, and a vertical plate 14 is fixedly installed on the lower side of the support plate 13. The vertical plate 14 is rotatably connected to the bidirectional threaded rod 15, the bidirectional threaded rod 15 is threadedly connected to the irregular plate 16, the irregular plate 16 is slotted to the limiting groove 17, the limiting groove 17 is fixedly installed on the lower side of the support plate 13, and a buffer column 18 is provided on the upper inner side of the irregular plate 16. The irregular plate 16, the limiting groove 17 and the buffer column 18 are all symmetrical about the vertical central axis of the support plate 13.

[0034] It should be noted that during use, the distance between the two irregularly shaped plates 16 needs to be adjusted first. Rotating the bidirectional threaded rod 15 will cause the two irregularly shaped plates 16 to move in opposite directions, making it easier to place the handheld laser rangefinder. Then, place the handheld laser rangefinder on the upper side of the support plate 13, so that one end of the handheld laser rangefinder contacts the baffle. Then, rotate the bidirectional threaded rod 15 in the opposite direction to move the two irregularly shaped plates 16 towards the middle, allowing the buffer column 18 to clamp the handheld laser rangefinder, thereby preventing the handheld laser rangefinder from shaking during the calibration process and avoiding errors. In addition, the limiting groove 17 limits the irregularly shaped plates 16, preventing them from contacting the support plate 13 and also preventing them from shaking and causing accidents. Specific Implementation

[0035] This embodiment is designed to solve the problem that the base 1 and the one-way threaded rod 2 are inconvenient to adjust.

[0036] like Figure 1 , Figure 5 and Figure 6 As shown, after the handheld laser rangefinder is installed on the upper side of the support plate 13, the support plate 13 needs to be adjusted to make it horizontal. The base 1 has multiple one-way threaded rods 2 arranged in an internal array. When one one-way threaded rod 2 is rotated, since the connection between the one-way threaded rod 2 and the spherical hole 5 is spherical, the other one-way threaded rods 2 and the spherical hole 5 will rotate, but the connection between the one-way threaded rod 2 and the spherical hole 5 will not be broken. Therefore, the support platform 3 can be adjusted to make the support platform 3 horizontal, thereby making the handheld laser rangefinder on the upper side of the support plate 13 horizontal, which is convenient for calibration. Specific Implementation

[0037] This embodiment is designed to solve the problem that the support plate 13 is inconvenient to rotate.

[0038] like Figure 1 , Figure 3 and Figure 4 As shown, when the support plate 13 needs to rotate, the limiting post 11 is pulled outward, and the spring 12 will undergo elastic deformation. The left side of the limiting post 11 will disconnect from the docking hole 9 in the toothed plate 7, allowing the toothed plate 7 to move back and forth. In addition, the toothed plate 7 has a slot 8 inside, which is slidably connected to the limiting block on the upper side of the support platform 3, thus limiting the toothed plate 7. When the toothed plate 7 moves, the connecting shaft 6 will rotate the support plate 13, thereby achieving the purpose of angle adjustment. Then, the limiting post 11 is released, and the spring 12 will restore its elastic deformation, allowing the limiting post 11 to move to the left and insert into the docking hole 9, thereby preventing the connecting shaft 6 from rotating.
