Abstract
The utility model relates to a laser line source. According to the laser line source provided by the utility model, defects are overcome, a light-transmitting protective cap is arranged at the outer side of a cylindrical mirror and a line straightness adjustment groove, and the problem that the cylindrical mirror is contaminated during the factory inspection and assembly of the laser line source is overcome. The laser line source comprises a line forming part and a point light source part, wherein the line straightness adjustment groove is formed between the line forming part and the point light source part, the protective cap is arranged at the outer side of the line straightness adjustment groove in a manner of continuously extending to the front end of the laser line source and is provided with a window corresponding to the cylindrical mirror, and a transparent plate is arranged on the window in a sealing manner. The laser line source provided by the utility model has the advantages that the protective cap is arranged, so that the cylindrical mirror is protected from damage during transportation, factory inspection and marking instrument assembly, the rate of finished products is increased, and the production cost is reduced.
Description
Technical field
The utility model relates to a kind of laser line light source.
Background technology
Laser level is widely used among construction work, and it has had both the function of original spirit-leveling instrument, transit line.It is projeced into work directrix on target accurately with laser lines, make work progress more convenient, more save time.Along with the development of technology, the application of laser level is also constantly expanded, and this performance to linear laser device light source itself is also had higher requirement.
As shown in Figure 1, laser line light source of the prior art generally all comprises into line part 6 and pointolite part 7, become line part 6 and pointolite part 7 that line is set and directly spend adjustment tank 4, become line part 6 to comprise successively cylindrical mirror 1, shadow shield 2, cylindrical mirror incidence hole 3, pointolite part 7 generally comprises planoconvex lens 5, for regulating frame for line marking instrument module line, directly spend, need on module shell, slot, can allow like this incidence surface of planoconvex lens 5 and cylindrical mirror 1 be exposed in air, easily by contamination by dust and cannot clear up dust, cause the straight line laser of getting to have veiling glare around, affect graticule quality.And the cylindrical mirror of laser rays module is directly exposed foremost, and for dustproof in transportation and protection, cylindrical mirror is easily polluted by air plankton or touched by operator, and some cylindrical mirrors, even by permanent damage, cause laser module to be scrapped.
Summary of the invention
The utility model overcomes above-mentioned defect, provides a kind of cylindrical mirror and line directly to spend adjustment tank arranged outside printing opacity head protector, has overcome the laser line light source of laser line light source in incoming test and the contaminated problem of assembling process central column face mirror.
The technical scheme of laser line light source of the present utility model is such: it comprises into line part, pointolite part, between one-tenth line part and pointolite part, line is set and directly spends adjustment tank, line is directly spent the front end that adjustment tank outside extends to laser line light source always head protector is set, the corresponding cylindrical mirror of head protector arranges window, and on window, sealing arranges transparent panel.
Optimally, transparent panel is set to glass plate.
Optimally, transparent panel is set to PMMA plate.
The line of the laser line light source of the technical program is directly spent outside adjustment tank and cylindrical mirror front end arranges head protector, and head protector leaves a window at cylindrical mirror front end, assembling transparent material in window, line source can be normally luminous through the transparent window of head protector, and whether producer can remove head protector according to the autonomous selection of the production technology of oneself, head protector window material can be PMMA, the transparent material that the refractive indexes such as glass are low, in the transportation of laser module and incoming test and frame for line marking instrument part assembling process, play online the effect of well preventing dust and protecting cylindrical mirror.
The laser line light source of the technical program arranges head protector outward: in transporting, enter factory's detection and frame for line marking instrument assembling process, protect cylindrical mirror injury-free, improve yield rate, reduce production costs.
Accompanying drawing explanation
Fig. 1 is the structural representation of the laser line light source of prior art;
Fig. 2 is the structural representation of laser line light source of the present utility model.
1-cylindrical mirror, 2-shadow shield, 3-cylindrical mirror incidence hole, 4-line are directly spent adjustment tank, 5-planoconvex lens, 6-one-tenth line part, 7-pointolite part, 8-head protector, 9-transparent panel.
Embodiment
Embodiment 1:
It comprises into line part 6, pointolite part 7 laser line light source of the present embodiment, between one-tenth line part 6 and pointolite part 7, line is set and directly spends adjustment tank 4, line is directly spent the front end that adjustment tank 4 outsides extend to laser line light source always head protector 8 is set, the corresponding cylindrical mirror 1 of head protector 8 arranges window, and on window, sealing arranges transparent panel 9.The transparent panel 9 of the present embodiment is set to glass plate.
Embodiment 2:
The difference of the present embodiment and embodiment 1 is, the transparent panel of the present embodiment is set to PMMA plate.
The foregoing is only preferred implementation of the present utility model, protection domain of the present utility model is not limited in above-mentioned embodiment, and every technical scheme that belongs to the utility model principle all belongs to protection domain of the present utility model.For a person skilled in the art, some improvement or the retouching under the prerequisite that does not depart from principle of the present utility model, carried out, these improvements and modifications also should be considered as protection domain of the present utility model.
