Description
Technical Field
The utility model belongs to the field of optical elements, and particularly relates to a laser cross-shaped light spot forming device.
Background
Laser level bar, spirit level are widely used in home decoration and building engineering, the light beam emitted by the laser level bar is expanded into cross light with orthogonal included angle for projecting mutually perpendicular cross light spot for positioning reference on the target object, the cross mirror is installed in the lens of the laser level bar and can be converted into mutually perpendicular cross light when the laser source irradiates the cross mirror.
At present, the existing laser cross light spot forming device is characterized in that cylindrical mirrors which are vertically connected with each other are arranged in a base groove, a laser light source is emitted from the bottom end of the base and can be refracted out from the cylindrical mirrors, the cross light source is formed by irradiating a target object with the cross light spot, but in the prior art, two cylindrical mirrors which are directly connected with each other, the cross light spot formed by irradiating the two cylindrical mirrors by a laser source in actual use can generate stray light to influence the cross light spot effect to be weakened, and the two cylindrical mirrors are easy to shift in position in the bonding process in actual production, so that the accuracy of a cross mirror instrument is reduced.
SUMMERY OF THE UTILITY MODEL
In order to solve the problems encountered in the background art, the utility model provides a laser cross-shaped light spot forming device, which comprises a base, the upper end surface of the base is provided with a groove which is a first groove and a second groove respectively, the first groove and the second groove are arranged vertically, a shading structure is arranged between the first groove and the second groove, a first cylindrical mirror is arranged in the first groove, a second cylindrical mirror is arranged in the second groove, the first cylindrical mirror and the second cylindrical mirror are separated by a shading structure, the first cylindrical mirror is arranged in the first groove through fixing glue, the second cylindrical mirror is arranged in the second groove through fixing glue, the laser light source is injected from the bottom end of the base and can be refracted out from the first cylindrical mirror and the second cylindrical mirror, and the cross light source is formed to irradiate on a target object to form a cross light spot.
Further, the shading structure can be replaced by a shading sheet.
The utility model has the advantages that the device is improved on the original cross-shaped light spot forming device, and the shading structure is additionally arranged between the first groove and the second groove which are perpendicular to each other, so that the first cylindrical mirror and the second cylindrical mirror are separated, stray light refracted by a laser source is reduced, the difficulty of assembling the cross-shaped mirror is reduced, and the quality and the assembling speed of the cross-shaped mirror are improved.
Drawings
Reference will now be made in brief to the drawings that are needed in describing embodiments or prior art.
FIG. 1 is a schematic diagram showing the structure of the present invention;
FIG. 2 is a schematic top view of the present invention;
FIG. 3 is a schematic side view of the present invention;
FIG. 4 is a schematic diagram showing a comparison of the three-dimensional structure of the present invention;
in the figure: the light shading structure comprises a base-1, a first groove-2, a second groove-3, a first cylindrical mirror-4, a second cylindrical mirror-5 and a light shading structure-6.
Detailed Description
As shown in fig. 1 and 4, the left side is a cross mirror in the prior art, the first cylindrical mirror is in direct contact with the second cylindrical mirror, when the parallel laser source irradiates the cylindrical mirror, light is easy to scatter from the contact point of the first cylindrical mirror and the second cylindrical mirror, so that the cross light spot forming effect is affected, and the right side is characterized in that a shading structure is added at the joint of the first cylindrical mirror and the second cylindrical mirror, so that the light is prevented from being easy to scatter from the first cylindrical mirror and the second cylindrical mirror, and the shading structure is formed on the base and is integrated with the base.
In light of the foregoing description of the preferred embodiment of the present invention, many modifications and variations will be apparent to those skilled in the art without departing from the spirit and scope of the utility model. The technical scope of the present invention is not limited to the content of the specification, and must be determined according to the scope of the claims.
Claims (2)
1. The utility model provides a cross facula forming device, includes the base, its characterized in that, the base up end is provided with the recess, the recess is first recess and second recess respectively, first recess sets up with second recess mutually perpendicular, be provided with the shading structure between first recess and the second recess, be provided with first cylindrical mirror in the first recess, be provided with second cylindrical mirror in the second recess, first cylindrical mirror separates through the shading structure with second cylindrical mirror mutually, first cylindrical mirror sets up in first recess through fixed glue, second cylindrical mirror passes through fixed glue and sets up in the second recess, and laser source jets into from the base bottom, can follow first cylindrical mirror and second cylindrical mirror refraction out, forms the cross facula that the cross light source shines and forms on the object of target.
