Description

The index device that has rotatable laser

Technical field

The utility model relates to a kind of straight line laser device, can send the covering of the fan laser beam, instructs as reference or auxiliary other operations at metope or other body surfaces formation straight line.

Background technology

Along with the development of technology, laser is applied to every field more and more.Especially recent years, the straight line laser device combines with each type electric tool, civilian instrument, perhaps uses more and more general separately.There are some producers also to realize the rotatable function of laser, thereby improved its functions of use to a greater degree.

Yet the laser whirligig often can't be realized the multi-angle location in the prior art, can only be positioned on certain some specific angle, as horizontal and vertical position; Though what have can rotate to different angles,,, cause the location inaccurate in use owing to reasons such as vibration cause positioning easily owing to do not locate reliably; Also have some can only realize the angle rotation of 0 to 90 degree.The notification number of my company's earlier application is that the Chinese patent of CN 2588326Y discloses the rotatable line laser marker of a kind of laser, its weak point is to realize the angle rotation of from 0 to 90 degree, and can only realize effectively location with vertical two positions in level.Aim at or sign level, vertical because line laser marker often is used as, degree of accuracy is had relatively high expectations, straight line laser device of the prior art is dealing with various requirements well.

The utility model content

The technical problems to be solved in the utility model is to realize the multi-angle rotation and location of laser.

To achieve these goals, the line laser marker that the utility model disclosed comprises a laser rotation and positioning system, this laser rotation comprises a fixture and a tumbler with positioning system, one of them of these two members contains all profiles of tooth mechanism, the another one member comprises the device that is meshed with described profile of tooth mechanism, and described laser rotation also comprises an elastic device with positioning system.

By the interaction of profile of tooth mechanism and its geared assembly, under the effect of elastic device, the covering of the fan light that line laser marker sent has not only been realized the rotation of 0 to 360 degree simultaneously, and can realize reliable location in a plurality of angles.

Embodiment

As shown in Figure 1, the index device that has rotatable laser 10 that the utility model disclosed mainly comprises casing 1, power-supply system 14, laser beam emitting device 5 and laser rotation and positioning system 2.Wherein the laser rotation comprises 3, one tumblers 4 of a fixture with positioning system 2, and a reed 6.Laser beam emitting device 5 is fixedlyed connected with tumbler 4, thereby the rotation of tumbler 4 can drive laser beam emitting device 5 and rotate together, thereby realizes the angle rotation of covering of the fan light.In concrete enforcement, tumbler 4 itself can be a laser beam emitting device, comprises prism and laser diode (not shown on the figure).Can also be 4 drive prism rotations of tumbler, laser diode maintains static, and can realize the laser spinfunction equally, and such conversion is conspicuous for those of ordinary skills.

To shown in Figure 5, reed 6 one ends are fixed on the fixture 3 as Fig. 2, and an other end is being fixed a steel ball 7 at its end position.Tumbler 4 outer rims are furnished with several alligators 9, steel ball 7 under the elastic reaction of reed 6 by the teeth groove 10 of roof pressure at tumbler 4 in.The sidewall 11 of teeth groove 10 is preferably inclined-plane as shown in Figure 3, so when tumbler 4 began to rotate under extraneous twisting force, 11 pairs of steel balls of sidewall 7 produced radial thrusts, makes its resistance that overcomes reed 6 along the climb top of alligator 9 of sidewall 11, as shown in Figure 5.Continue rotation tumbler 4, then steel ball is in sidewall 11 is slipped to another teeth groove 10.As seen, because being meshing with each other of the compressing of reed 6 and steel ball 7 and teeth groove 10 when steel ball 7 is positioned at teeth groove 10, just forms a spacing point, need apply a torsion that enough overcomes above-mentioned acting force to tumbler 4, tumbler 3 could rotate.So realized the reliable location of a plurality of angles in 360 degree.In concrete enforcement, can also realize more accurate localization of more perspective by increasing the alligator number.

Steel ball 7 in the above-mentioned embodiment also can be spherical or along the cylindrical member of teeth groove direction, even can be the projection of other shapes.In addition, reed also can be fixed on the tumbler, conversely on the fixture circumference cloth with alligator, can realize equally aforesaid 360 the degree multi-angles reliably locate.

Fig. 6 is the schematic cross-section of laser rotation and positioning system 21 in second kind of embodiment of the utility model.Fixture 31 has at least a part to be positioned at the cavity of tumbler 41, and three springs 61 radially are housed in its body, between the teeth wall of the top of spring 61 and tumbler 41 inside a steel ball 71 is arranged respectively.Three auxiliary springs 61 in the present embodiment are not inevitable with steel ball 71, also can be a pair, two pairs according to actual needs, perhaps more than three pairs.With above-mentioned first kind of embodiment as a same reason, rotation is during tumbler 41, steel ball 41 and the alligator generation effect of spring 61 to its inwall, thereby realize positioning function.

Fig. 7 is the schematic cross-section of laser rotation and positioning system 22 in the third embodiment of the utility model.Functional structure is all similar to the third embodiment, and just tumbler 42 is positioned at fixture 32.

Above-mentioned second and third kind embodiment medi-spring also can be positioned on the tumbler, at fixture outer rim cloth with alligator.

In the 4th kind of embodiment of the present utility model, as Fig. 8 and shown in Figure 9, the laser rotation comprises fixture 33, tumbler 43 and spring 63 with positioning system 23.The radial tooth 44 of one circle is respectively arranged on the opposite face of tumbler 43 and fixture 33, can be meshing with each other.Fixture 33 other ends are subjected to the effect of guide 13, can only do the relative motion of arrow among Fig. 8 " A " direction, can't realize rotating.Spring is between fixture 33 and guide 13.As the external force effect, when making tumbler 43 begin to rotate with respect to fixture 33, intermeshing each tooth is slided along the other side's teeth groove sidewall respectively, crown breaks away from the other side's tooth root, fixture 33 compression springs, when arriving the position that crown contacts with each other, the spring amount of being compressed maximum; Continue the rotation tumbler, under the effect of spring pressure, tooth slips into the other side's teeth groove again, realizes engagement once more.So tumbler 43 whenever slips over the position of a tooth, just realize one-time positioning, equally also can realize the rotation of 360 degree.

As shown in Figure 1, tumbler 4 preferably comprises a knob 40, and the operator can rotate tumbler 4 by rotary knob 40, thereby realizes the rotation of laser angle.Indicate scale 100 and arrow 101 respectively on the adjacent circumference of knob 40 and casing 1.As shown in figure 10, make arrow 101 indicated scales 100 increase or reduce the reading of a α degree when knob 40 turns over an angle, then laser formed straight line on metope also correspondingly turns over the α degree.The position of scale 100 and arrow 101 is not well-determined, can be positioned on other positions and fixed part of rotatable member yet.

The index device that has rotatable laser 10 that the utility model disclosed both can be used alone as the graticule device, also can be used in combination with each type electric tool, civilian instrument.

Straight line laser device in the utility model is not limited to above embodiment, also can make other form and reaches identical purpose.
