Description of drawings
The present invention is further detailed explanation below in conjunction with the drawings and specific embodiments.
Fig. 1 is the stereographic map of the line laser marker in first-selected embodiment of the utility model.
Fig. 2-the 4th, the cut-away view of line laser marker shown in Figure 1.
Embodiment
Shown in Fig. 1-4, the line laser marker 10 of a first-selected embodiment of the utility model comprises laser rays generating means 20, base 30.
Laser rays generating means 20 comprises 29, one of casings and is contained in laser instrument 21 in the casing 29.Laser instrument 21 and a power supply (not shown) are electrically connected.At laser instrument 21 front ends a laser rays is housed and forms lens, make the laser beam of sending from laser instrument 21 be converted into a branch of covering of the fan light ejaculation casing 29, covering of the fan light projects and forms a laser rays on the surface of placing line laser marker.It is a cylindrical lens that laser rays forms lens first-selectedly, can certainly be other forms of lens.
One circular port 27 is arranged at the bottom of casing 29.A tumbler 26 has the circular port 27 that casing 29 bottoms are passed by a first 261 that cylindrical outer surface arranged, and the diameter in first 261 cross sections and the diameter of circular port 27 match.A flat second portion 262 of tumbler 26 is positioned at first 261 near on the end of casing 29 bottoms, and is set at casing 29 inside.Tumbler 26 also has one and is positioned on first's 261 other ends and the coaxial third part with cylindrical outer surface 263 of first, and its diameter of section is littler than the diameter of section of first 261.A bearing 264 is contained on the third part 263 of tumbler 26.Base 30 structures own form a circular shrinkage hole 34 of holding bearing 264.A cover plate 33 has the hole of a slightly larger in diameter in first's 261 diameter of sections of tumbler.Cover plate 33 is contained between the upper surface of casing 29 bottom surfaces and base 30, and the hole of cover plate 33 is passed by the first 261 of tumbler 26.Cover plate 33 by screw retention on base 30, thereby bearing 264 is limited in the shrinkage pool 34 of base 30.By said structure, tumbler 26 connects together laser rays generating means 20 with base 30, and makes that the two can be that turning axle relatively rotates with the central axis of tumbler 26 firsts 261.Those of ordinary skill in the art can be easy to expect that tumbler can also have a lot of modifications and deformation program, and tumbler can also be made of one with the casing of laser rays generating means in addition.
In this embodiment, on base 30 upper surfaces, be that the center has a calibration loop 50, the angle that can indicate generating device of laser 20 to be turned over respect to base 30 with this turning axle.In other embodiments of the present utility model, also can be between the two or electronic type angle induction display device is installed on one of them at generating device of laser 20 and base 30, be used to show counterrotating angle between the two, for example the patent No. is 4,064, the relative angle induction display devices that disclosed in 504 the United States Patent (USP) etc. can also be used as the angle induction display device with tilt sensor.
The annular groove 35 that on the upper surface of base 30, also has first's 261 coaxial lines of and tumbler 26.An O type rubber seal 45 is contained in the annular groove 35 and with the bottom surface of laser rays generating means 20 casings 29 and contacts.On the one hand, O-ring seal 45 is used to seal the bottom surface of laser rays generating means 20 and the slit between base 30 upper surfaces, prevents that outside foreign material such as dust from entering the inside of line laser marker 10.On the other hand, because the friction force effect between the bottom surface of O-ring seal 45 and generating device of laser 20 casings 29, make laser rays generating means 20 under the situation of the external force effect that does not have a certain size, can not rotate arbitrarily, thereby guaranteed the stability of the relative position between laser rays generating means 20 and the base 30 with respect to base 30.
A flange 25 has a center pit, the third part 263 outside surface wringing fits of this center pit and tumbler, thus flange is fixed on the third part 263 of tumbler.Transmission component comprises an annular element 411, a friction member 413.In the present embodiment, friction member 413 first-selections is an O type rubber seal.Annular element 411 has into stair-stepping through hole, and this through hole has and forms annular groove 412 between the inwall of larger-diameter first and flange 25 outer walls.Friction member 413 is contained in the annular groove 412, and is subjected to the extruding force effect of annular element 411 inwalls and flange 25 outer walls.Annular element 411 through holes also have the second portion that has than minor diameter, the diameter of this second portion is bigger than the diameter of section of the third part 263 of tumbler 26, thereby make some when being applied in certain torsion and having overcome friction force between the two and the friction member 413 in the two of annular element 411 or tumbler 26, can rotate with respect to another.Cover plate 24, is limited in the groove 412 friction member 413 to prevent that it from coming off from groove on flange 25 by screw retention.Also have 414, one rollers 415 of an outshot to be contained on the end of outshot 414 on the side of annular element 411.
U-shaped support 43 by screw retention in base 30.Actuating assembly comprises 421, one skewbacks 422 of a screw rod.One end of a screw rod 421 is contained on the boss 431 on U-shaped support 43 bottoms, and its longitudinal axis is perpendicular to the bottom of U-shaped support 43, and this screw rod 421 can rotate around this longitudinal axis.Skewback 422 with the threaded hole 423 that matches with screw rod 421 is contained on the screw rod 421.Knob 41 is contained in the other end of screw rod 421, and its part is exposed base 30, manually makes its rotation with the handled easily person.Skewback 422 has an inclined-plane 424 that favours the screw rod longitudinal axis.Also has a groove 432 on the arm 431 of U-shaped support 43.One end of spring 433 is contained in the groove 432, the other end leans against on the side of outshot 414 of annular element 411, towards perpendicular to applying a pressure to outshot 414 on the direction of screw rod 421 longitudinal axis, thereby roller 415 is pressed in all the time on the inclined-plane 424 of skewback 422.
When the operator roughly reaches an angle on target with laser rays generating means 20 with respect to base 30 rotations, operator's rotary knob 41 again drives screw rod 421 rotations, skewback 422 makes progress or moves down at this moment, and under spring 4323 actings in conjunction, drive roller 415 and annular element 411 left or to right rotation, and drive tumblers 26 and laser rays generating means 20 left or to right rotation, thereby reach the purpose of the relative angle between meticulous adjusting laser rays generating means 20 and the base 30 by friction member 413.Because roller 415 makes that with respect to the rolling on skewback 422 inclined-planes 424 outshot 414 of annular element 411 is more smooth and easy with respect to the motion on inclined-plane 424, thereby further improved the comfort level of the meticulous adjusting operation of angle.
Embodiment described above is just set forth design of the present utility model and principle, does not really want content of the present utility model is limited.Those of ordinary skill in the art can recognize, except the embodiment of above-mentioned first-selection, the utility model also has a lot of other embodiments that substitute or that revise, and these embodiments alternative or that revise are still within scope of the present utility model.Protection domain of the present utility model is determined by claim.
