Description

Technical Field

[0001] This utility model relates to the field of level technology, specifically to a level that allows for easy adjustment of the laser angle. Background Technology

[0002] A laser emitter is integrated into the traditional level, and a visual measurement is achieved by projecting a laser line (green or red light). For example, the brightness of green laser is 4 times that of red laser, making it clearer in strong light environments and suitable for outdoor or well-lit indoor environments. Based on the effect of gravity, the position of the bubble in the sealed glass tube determines whether the plane is horizontal or vertical.

[0003] The laser level first establishes a reference point: relying on gravity sensing elements (such as traditional bubble levels or electronic MEMS accelerometers) to detect the direction of Earth's gravity—in a horizontal state, the direction of gravity is perpendicular to the horizontal plane; in a vertical state, the direction of gravity is parallel to the vertical plane. The sensor continuously monitors whether the device deviates from this reference point. Secondly, laser projection occurs: a laser emitter (red / green diode) converts a point light source into a linear beam through a prism or lens, ensuring that the projected beam is a straight line. The direction of this line precisely matches the horizontal / vertical reference point determined by the sensor.

[0004] Laser levels have the following drawbacks: they generally cannot rotate the laser projector, which means that when testing a 90-degree vertical plane, the level needs to be recalibrated against the vertical wall, making the overall operation process cumbersome. To address this issue, a level that allows for easy adjustment of the laser angle is proposed. Utility Model Content

[0005] The purpose of this invention is to provide a level that allows for easy adjustment of the laser angle, thereby solving the problem in the prior art where the laser projector cannot be rotated, which necessitates recalibrating the level against the vertical wall when testing a 90-degree vertical plane.

[0006] To achieve the above-mentioned technical objectives, the technical solution of this utility model is implemented as follows:

[0007] A level for easy adjustment of laser angle includes a housing, a horizontal level and a vertical level in the middle of the housing, a laser emitter at one of the lateral ends of the housing, a through hole near the middle of the laser emitter, a connecting post through the through hole inside the housing, and a receiving cavity with an open top adapted to the laser emitter inside the housing. The laser emitter is located in the receiving cavity and can rotate along the circumference of the connecting post. An arc surface is provided at one end of the laser emitter near the middle of the housing, and an elastic protrusion is provided on the arc surface. A spring piece is provided in the receiving cavity at a position corresponding to the arc surface, and the spring piece has a groove adapted to the elastic protrusion.

[0008] Furthermore, the spring is provided with three slots. When the elastic protrusion engages with the three slots respectively, the laser emission direction of the laser emitter is 0 degrees, 45 degrees and 90 degrees with the horizontal direction respectively.

[0009] Furthermore, the outer surface of the housing is provided with indicator lines corresponding to the 0 degrees, 45 degrees and 90 degrees respectively.

[0010] Furthermore, a steel measuring tape is provided at the other end of the casing in the lateral direction.

[0011] Furthermore, the lower part of the shell is provided with a magnet receiving compartment containing a magnet, and the lower end of the magnet receiving compartment is provided with an aluminum alloy base that snaps into the shell.

[0012] Furthermore, a tripod mounting nut is fixedly provided on the upper surface of the aluminum alloy base, and a connecting screw hole is provided on the aluminum alloy base that is connected to the tripod mounting nut.

[0013] The beneficial effects of this utility model are as follows: The laser emitter of this utility model can rotate from 0 to 90 degrees with the horizontal direction, and is equipped with an elastic structural positioning point, which allows users to easily position the angle of the laser emitter, breaking the conventional limitation of only being able to position one angle, and greatly improving the work efficiency of users; the addition of aluminum alloy edge strips at the bottom makes the plane of the level more solid and accurate, and the addition of magnets and nuts at the bottom makes the level suitable for various working occasions.

A spring piece 10 is provided in the cavity 7 at a position corresponding to the arc surface 8. The spring piece 10 is provided with three slots 11 that are adapted to the elastic protrusion 9. When the elastic protrusion 9 is engaged with the three slots 11 respectively, the laser emission direction of the laser emitter 4 is 0 degrees, 45 degrees and 90 degrees with the horizontal direction respectively. The outer side of the housing 1 is provided with indicator lines 12 corresponding to the 0 degrees, 45 degrees and 90 degrees respectively, so that users can quickly judge whether the current laser angle meets the requirements. The outer side of the indicator lines 12 can be coated with a conspicuous coating so that users can see the indicator lines 12 even in a dark environment.
