Description

Technical Field

This leveling method will cause the laser line to shake, and it will take several swings for the laser line to stabilize. Moreover, when the level is placed on a surface with an angle, the weight will automatically swing to a new position, but the center of gravity will shift, causing the level to easily tip over.

DETAILED DESCRIPTION

[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] See also Figure 1-7 In the embodiment of the utility model, a digital level automatic leveling structure includes a hanger 17 for laser installation, the upper end of the hanger 17 is movably connected to a U-shaped groove at the bottom of a movable block 11 through a connecting shaft; the upper end of the movable block 11 is movably connected to a rotating shaft 10, and the connecting shaft of the rotating shaft 10 and the upper end of the hanger 17 is arranged in a cross shape;

[0032] The stretching spring 12 used for stretching and adjusting the movable block 11 is arranged obliquely, one end of which is buckled with the top frame 9, and the other end is buckled with the lower side of the movable block 11; a first threaded barrel 13 is movably connected on the other side of the movable block 11, and the first threaded barrel 13 is internally threaded with a first screw rod 14; the first screw rod 14 is connected in cooperation with the output shaft of the first motor 15; a second threaded barrel 22 is provided at the bottom of the hanger 17, and the second threaded barrel 22 is connected in cooperation with the second screw rod 21; and one end of the second screw rod 21 is connected in cooperation with the output shaft of the second motor 20.

[0033] The second motor 20 is fixed on the side plate 19; the upper end of the side plate 19 is fixed to the movable block 11. The second threaded barrel 22 is arranged in the U-shaped groove of the hanger 17, and the end of the second threaded barrel 22 away from the second screw rod 21 is movably connected in the U-shaped groove through a rotating shaft.

[0034] By adopting the above technical solution, when the level is used, if the level is deflected due to uneven terrain, if X-axis adjustment is required, the first motor 15 drives the first screw rod 14 to rotate, and the first threaded barrel 13 and the first screw rod 14 are extended or shortened in fit, and the tension spring 12 on the other side of the movable block 11 is deformed, resulting in relative changes, thereby achieving X-axis adjustment of the level, ensuring that the laser emitted by the X-axis laser 23 can be perpendicular to the ground; during adjustment, since the movable block 11 deflects around the rotating shaft 10, there will be a certain inclination angle, and the first threaded barrel 13 is movably connected to the movable block 11 through the shaft, which can produce a certain angle change during adjustment, providing sufficient angle compensation for the deflection of the movable block 11, and ensuring the adjustment effect;

[0035] If Z-axis adjustment is required, the second motor 20 drives the second screw rod 21 to rotate, and the angle adjustment of the hanger 17 is achieved by changing the fit between the second screw rod 21 and the second threaded tube 22. During adjustment, the hanger 17 deflects around the axis between it and the movable block 11, thereby achieving angle adjustment. Since the end of the second threaded tube 22 away from the second screw rod 21 is movably connected to the U-shaped groove through a rotating shaft, it can provide a deflection displacement during Z-axis adjustment to ensure Z-axis adjustment.

[0036] The above adjustment method is relatively stable, and the laser line can be slowly changed until the laser line is perpendicular to the ground; the laser line will not swing.

[0037] In this embodiment, two lasers are provided, namely an X-axis laser 23 and a Z-axis laser 24; the X-axis laser 23 and the Z-axis laser 24 are installed on two adjacent surfaces of the hanger 17, and are respectively installed on the inner sides of the X-axis laser lampshade 2 and the Z-axis laser lampshade 3.

[0038] By adopting the above technical solution, windows are opened on all sides of the X-axis laser lamp cover 2 and the Z-axis laser lamp cover 3 to facilitate laser projection, and the windows are all glass reflective windows. The laser lines emitted by the X-axis laser 23 and the Z-axis laser 24 will become rectangular wire frames, which can realize multi-axis line testing horizontality.

[0039] In this embodiment, an angle sensor 18 is also provided at the bottom of the hanger 17, and the angle sensor 18 is electrically connected to the control board 26; the X-axis laser 23 and the Z-axis laser 24 are both electrically connected to the control board 26 and the battery 27; the control board 26 is also electrically connected to the display screen 4. The battery 27 is fixed between the top frame 9 and the frame plate 25; the control board 26 is fixed on the frame plate 25.

[0040] By adopting the above technical solution, the angle sensor 18 can monitor the inclination angle of the level and transmit the detection information to the control board 26. The control board 26 issues instructions based on the information fed back by the angle sensor 18, and realizes the corresponding adjustment of the inclination angle through the action of the first motor 15 or the second motor 20.

[0041] In this embodiment, both ends of the rotating shaft 10 are movably connected to the top frame 9 through bearings; the top frame 9 is fixed to the upper end of the bracket 6; and the bracket 6 is fixed on the rotating frame 5.

[0042] Specifically, the rotating frame 5 is fixed on the top of the turntable 7, and the turntable 7 is movably connected to the inside of the base 8 through a slip ring.

[0043] By adopting the above technical solution, the rotating frame 5 can be rotated in conjunction with the turntable 7, so that the laser can be directed to every corner of the room, and adjustment is more convenient.

[0044] In this embodiment, the X-axis laser lamp cover 2 and the Z-axis laser lamp cover 3 are arranged on the outside of the shell 1, and the shell 1 covers the outside of the rotating frame 5, the bracket 6 and the top frame 9, and the bottom is fixed to the rotating frame 5 by screws.

[0045] In this embodiment, the display screen 4 is embedded in the top of the housing 1 , and buttons and switches are also provided on one side of the display screen 4 , which are electrically connected to the control board 26 .

[0046] By adopting the above technical solution, the horizontal power supply can be controlled by the switch, the corresponding laser can be selected to be turned on by pressing the button, and the display screen 4 can display the deflection, thereby facilitating automatic leveling.

[0047] The working principle of the utility model is as follows: when in use, if the level is deflected due to uneven terrain, if X-axis adjustment is required, the first motor 15 drives the first screw rod 14 to rotate, and the first threaded barrel 13 and the first screw rod 14 are extended or shortened in fit, and the tension spring 12 on the other side of the movable block 11 is deformed, resulting in a relative change, thereby achieving X-axis adjustment of the level, ensuring that the laser emitted by the X-axis laser 23 can be perpendicular to the ground; during adjustment, since the movable block 11 deflects around the rotating shaft 10, there will be a certain inclination angle, and the first threaded barrel 13 is movably connected to the movable block 11 through the shaft, which can produce a certain angle change during adjustment, providing sufficient angle compensation for the deflection of the movable block 11, and ensuring the adjustment effect;

[0048] If Z-axis adjustment is required, the second motor 20 drives the second screw rod 21 to rotate, and the angle adjustment of the hanger 17 is achieved by changing the fit between the second screw rod 21 and the second threaded tube 22. During adjustment, the hanger 17 deflects around the axis between it and the movable block 11, thereby achieving angle adjustment. Since the end of the second threaded tube 22 away from the second screw rod 21 is movably connected to the U-shaped groove through a rotating shaft, it can provide a deflection displacement during Z-axis adjustment to ensure Z-axis adjustment.
