Problems solved by technology

However, the combination of traditional lasers and rod mirrors to obtain line light sources generally has disadvantages such as fixed opening angle, poor energy uniformity, and low brightness in the distance, which limits the application of laser line projectors.
In practical application, if the distance is longer, the energy will be scattered due to the larger opening angle. There is also the problem of insufficient energy concentration when used in a brighter environment. If the opening angle can be adjusted to make the energy more concentrated, the instrument will be greatly expanded. Applications

Embodiment 1

[0025] refer to figure 1 , the laser line projector of this embodiment includes a light source, a lens, and a light exit hole 2. The light emitted by the light source is adjusted by the lens and then emitted from the light exit hole. The lens is composed of lens modules with more than two refractive indices, and the position of each lens module All can be adjusted between the light exit hole and the light source. The lens is set as a rod lens, and the rod lens module is set as a rod lens module with more than two refractive indices. The rod mirror module rod mirror clamping slider 3 clamps and drives it to move in the axial direction.

Embodiment 2

[0027] The difference between this embodiment and Embodiment 1 is that the rod mirror module 1 of this embodiment is fixed on the rod mirror bracket 4 that rotates around a fixed axis, and is driven by the rod mirror bracket 4 to rotate between the light source and the light exit hole. When using a rod mirror, rotate the rod mirror between the light source and the light exit hole.

Embodiment 3

[0029] Such as Figure 4 As shown, the difference between this embodiment and Embodiment 1 is that the cylindrical mirror is set to two ， The lens is set as a cylindrical mirror, and the focus degree of the light is changed by moving the position of the cylindrical mirror to change the size of the fan angle. There are two cylindrical mirrors, the two cylindrical mirrors are set as plano-convex cylindrical lenses 5, the planes of the two plano-convex cylindrical lenses 5 are opposite, and the distance between the two plano-convex cylindrical lenses is adjustable. As shown in the figure above, the point light source passes through two cylindrical mirrors placed in parallel. The two cylindrical mirrors are assembled together by the upper and lower guide rails 6. One of the plano-convex cylindrical lenses is fixed, and the other can slide left and right in the guide rails. Different positions of the plano-convex cylindrical lenses correspond to the line spots with different degre...

Abstract

The invention belongs to the field of laser demarcation devices and provides a laser demarcation device with an adjustable laser ray module fan angle. The laser demarcation device comprises a light source, a lens and a light emitting hole, wherein light emitted from the light source is adjusted by the lens and emitted through the light emitting hole, the lens comprises lens modules with more than two refractive indexes, and the position of each lens module can be adjusted to the position between the light emitting hole and the light source. The flare angle of the laser demarcation device can be adjusted, the laser demarcation device can be applicable to various different environments, and the application distance and the application range of the laser demarcation device are broadened.

Description

technical field [0001] The invention belongs to the field of laser line throwing instruments. Background technique [0002] The laser line throwing instrument is widely used in construction projects, and it has the functions of the original level and theodolite marking. It uses laser lines to accurately project the working alignment on the working object, making the construction process more convenient and time-saving. With the continuous development of technology, the application fields of laser line projectors have also been continuously expanded, which also puts forward higher requirements for the performance of the line projector light source itself. [0003] At present, the line light sources on the market mainly rely on traditional lasers to obtain point light sources, and then diverge in one direction through rod mirrors or cylindrical mirrors to obtain linear light spots. However, the combination of traditional lasers and rod mirrors to obtain line light sources ge...
