[0022] Participation Figures 1-4The utility model provides a bidirectional laser emitting device, which comprises a base 1, a mounting box 2 arranged on the base 1, coaxial through holes 3 arranged on opposite side walls of the mounting box 2, two identical convex lenses 10 arranged in the mounting box 2, the focal points of the two convex lenses 10 coinciding, all the focal points of the two convex lenses 10 being on a straight line L4, the straight line L4 penetrating the two through holes 3, two lasers 5 arranged on the base 1 outside the mounting box 2 through lifters 7, the lifting direction of the lifters 7 being perpendicular to the straight line L4, and the light emitted by the lasers 5 being parallel to the straight line L4; after the lifters 7 are lifted, the light emitted by the lasers 5 can penetrate the mounting box 2 through the through holes 3.

[0023] In the present application, when used, as shown in the drawings, Figure 4 When laser needs to be emitted to the right, the left laser 5 is lifted by the lifter 7 to the position where the light emitted by the left laser 5 can penetrate the mounting box 2 through the through hole 3, then the light a emitted by the left laser 5 is focused into a point by the left convex lens 10 and is collimated into light b by the right convex lens 10; conversely, when laser needs to be emitted to the left, the right laser 5 is lifted by the right lifter 7 to the position where the light emitted by the right laser 5 can penetrate the mounting box 2 through the through hole 3, then the light c emitted by the right laser 5 is focused into a point by the right convex lens 10 and is dispersed by the left convex lens 10 and is collimated into light d. In the whole process, the base 1 and the box 2 need to be rotated, and only different lasers 5 need to be turned on to realize the rotation of the light by 180 degrees. The lifter 7 is mainly arranged to avoid the left laser 5 from blocking the light when the light needs to be emitted to the left and to avoid the right laser 5 from blocking the light when the light needs to be emitted to the right.

[0024] As a preferred mode, the straight line L4 penetrates the center of the through hole 3. This arrangement makes the whole device more coordinated.

[0025] As a preferred mode, a plane glass 6 is arranged at the through hole 3 of the mounting box 2. The arrangement of the plane glass 6 does not affect the emission of the light, and the plane glass 6 can prevent dust or steam and other media that can affect the propagation of the light from entering between the two convex lenses 10, that is, dust and steam from entering the mounting box 2.

[0026] As a preferred mode, the mounting box 2 is made of opaque material. This arrangement prevents external light from entering the convex lens 10.

[0027] As a preferred embodiment, the base 1 has an upward-opening mounting cavity 11 outside the mounting box 2, and the lifting device 7 is disposed within the mounting cavity 11. This arrangement allows the lifting device 7 to retract the laser 5 into the mounting cavity 11 when not in use, preventing the laser 5 from being damaged by collisions. This serves to protect the laser 5.

[0028] As a preferred embodiment, the lifting device 11 includes a pneumatic cylinder or a hydraulic cylinder.

[0029] As a preferred embodiment, the top plate of the mounting box 2 is a detachable structure. This design facilitates the installation of the convex lens 10 during manufacturing.

[0030] As a preferred method, such as Figure 3 As shown, the mounting box 2 has two vertical grooves 8 on each of the inner sidewalls on both sides of the straight line L4. Each convex lens 10 has a mounting frame 9 wrapped around its outer edge, and the mounting frame 9 is installed inside the mounting box 2 through the grooves 8. The grooves 8 are designed to facilitate inserting the edge of the mounting frame 9 into the grooves 8 after removing the top cover of the mounting box 2, thereby installing the convex lens 10 inside the mounting box 2.
