[0021] 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.
[0022] Please see Figure 1 and Figure 2 This utility model provides a technical solution: an automatic laser horizontal rangefinder, including: a base 1, a top cover 2, a control panel 3, a laser rangefinder module 4, and a level module 11; the top cover 2 is connected to the top of the base 1 by screws, the control panel 3 is fastened to the inner wall of the top cover 2 by clips, and the laser rangefinder module 4 is connected to the inner wall of the top cover 2 near the bottom of the control panel 3 by screws.
[0023] This automatic laser horizontal rangefinder has a battery compartment at the bottom of the base 1, containing a rechargeable battery. Two electronic wires power the laser rangefinder module 4 and the level module 11. The level module 11 uses a commercially available laser line module. The base 1 and the top cover 2 are fixed together with screws. The upper surface of the top cover 2 has a raised hemisphere that blocks the control panel 3, preventing it from detaching from the inner wall of the top cover 2. The top cover 2 and control panel 3 can be made of plastic, allowing the control panel 3 to be pried off from the inside of the top cover 2. The button on the control panel 3 near the display screen is the power button; pressing and holding it powers on the laser rangefinder module 4 and powers it. The control buttons on the control panel 3 control the display screen and thus the laser rangefinder module 4. Two through holes on one side of the top cover 2 allow the laser from the laser rangefinder module 4 to pass through. The laser rangefinder module 4 emits a laser line, which is reflected by the object being measured. Based on the speed of the laser line and the reception time, the distance between the laser rangefinder module 4 and the object being measured is calculated.
[0024] exist Figure 2 and Figure 3 In the middle, a lifting frame 5 is connected to the inner wall of the base 1 by screw posts, an x ball bearing 6 is connected to the inner wall of the lifting frame 5, and a cross shaft 7 is connected through the x ball bearing 6.
[0025] In this laser automatic horizontal rangefinder, the x-ball bearing 6 reduces the resistance when the cross shaft 7 rotates. The x-ball bearing 6 is installed on the lifting frame 5 and the cross shaft 7 by glue or screws, allowing the cross shaft 7 to swing to both sides.
[0026] exist Figure 3 and Figure 4 In the middle, a Y-ball bearing 8 is connected to the outer side of the cross shaft 7, a pendulum 9 is connected to the outer side of the Y-ball bearing 8, and a copper ring 10 is connected to the lower part of the cross shaft 7 by screws.
[0027] In this laser automatic leveling rangefinder, the ball bearing 8 reduces the resistance of the pendulum 9 during rotation. The mounting frame 5 is installed on the cross shaft 7 and the pendulum 9 by glue or screws, allowing the pendulum 9 to swing back and forth. The weight of the copper ring 10 keeps the pendulum 9 vertically downward and leveled by its weight. The pendulum 9 swings along the front of the cross shaft 7, and the cross shaft 7 swings to both sides inside the upper cover 2, keeping the copper ring 10 perpendicular to the ground, thereby keeping the leveling module 11 level.
[0028] exist Figure 3 and Figure 4 In the middle, a level module 11 is connected to the inner wall of the pendulum 9 by screws.
[0029] The automatic laser horizontal rangefinder has an opening on one side of the top cover 2, allowing the laser emitted by the level module 11 to pass through and project a crosshair laser line onto the background of the object. The crosshair laser line is aligned with the vertical angle of the object to detect whether the object is vertical. When the automatic laser horizontal rangefinder leaves the factory, the top cover 2 is opened, the crosshair laser emitted by the level module 11 is irradiated onto the target, and the position of the level module 11 is finely adjusted with tools to perform factory calibration.
[0030] exist Figure 1 , Figure 2 and Figure 5 In the middle, a slot 12 is provided on one side of the inner wall of the base 1, and a push handle 13 slides through the inner wall of the slot 12.
[0031] This laser automatic horizontal rangefinder can push the push handle 13 to slide back and forth in the slot 12.
[0032] exist Figure 2 and Figure 5 In the middle, the outer side of the push handle 13 abuts against the first gripper 14, and the upper part of the first gripper 14 is rotatably connected to the second gripper 15 via a rotating shaft.
[0033] When the push handle 13 is pushed, the first gripper 14 rotates, which in turn pushes the second gripper 15 to rotate. The first gripper 14 and the second gripper 15 clamp the copper ring 10, and at the same time, the power to the level module 11 is cut off, causing it to stop swinging quickly. This prevents the pendulum 9 from swinging due to swaying force when idle or during transportation. When the push handle 13 is pushed in the opposite direction, the first gripper 14 and the second gripper 15 are released from the copper ring 10. At this time, the level module 11 is powered on. There is a magnet in the base 1. When the copper ring 10 swings, it cuts the magnetic lines of force, generating current. The circuit board controls the level module 11 to flash. After the level module 11 is kept level, the copper ring 10 stops swinging, and the level module 11 remains lit.
[0034] exist Figure 2 In the middle, the first gripper 14 and the second gripper 15 are both rotatably connected to the inner wall of the base 1 by screws.
[0035] The laser automatic horizontal rangefinder has multiple sets of screw posts installed on the lower inner wall of the base 1 to support the lifting frame 5, the first gripper 14 and the second gripper 15. When the upper cover 2 is placed on the base 1, the screw posts abut against the upper inner wall of the upper cover 2. Screws are used to penetrate the upper inner wall of the upper cover 2 and fix it to the screw posts, thus installing the base 1 and the upper cover 2 together.
[0036] In summary: When using this automatic laser horizontal rangefinder, first, carry the device using the handle on the top cover 2 and place it in front of the object to be measured. Then, operate the button on the control panel 3 to make the laser rangefinder module 4 emit a laser. The laser rangefinder module 4 measures the distance between the object and the device and displays the result on the screen of the control panel 3. Push the push handle 13 to power on the level module 11 and push the device to align it with the horizontal and vertical planes of the object being measured. After the laser line emitted by the level module 11 stops wobbling, observe whether the laser line emitted by the level module 11 is straight with the vertical and horizontal planes of the object being measured to check whether the object is vertical. After checking, push the push handle 13 in the opposite direction to clamp the copper ring 10, de-energize the level module 11, and operate the control panel 3 to turn off the laser rangefinder module 4. Hold the handle on the top cover 2 and take the device away. The content not described in detail in this description belongs to the prior art known to those skilled in the art.
[0037] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
