Description
Technical field
The invention belongs to laser level fields.
Background technique
Laser level is widely used among architectural engineering, it has had both the function of original level, theodolite scribing line.
Work directrix is accurately projeced on target by it with laser lines, keeps work progress more convenient, more time saving.With technology
Continuous development, the application field of laser level also constantly expanded, this also proposed the performance of level light source itself
Higher requirement.
Linear light source is obtained currently on the market relies primarily on conventional laser acquisition point light source again through stick mirror or cylindrical mirror folk prescription
To diverging to obtain linear hot spot.But it arranges in pairs or groups to obtain the generally existing subtended angle size of linear light source using conventional laser and stick mirror solid
Calmly, the disadvantages such as energy uniformity is poor, distant place brightness is low, limit the application of laser level.In practical applications, using distance
The problems in then power dissipation due to subtended angle is larger farther out, not enough collect when being used under brighter environment there is also energy, if
Angle is adjustable and the application of instrument will be greatly expanded by concentrating energy more.
Summary of the invention
In order to solve the above problem existing for current laser level, the present invention provides a kind of laser rays mould group fan angle can
The laser level of tune, specific technical solution are as follows:
A kind of laser level comprising light source, lens, light hole, the light that light source issues is after lens adjust by going out
Unthreaded hole projects, and lens are made of the lens module of two or more refractive index, and the position of every kind of lens module is all adjustable to out
Between unthreaded hole and light source.
Optimally, lens are set as stick mirror, and stick mirror module is set as the stick mirror module of two or more refractive index.
Further, stick mirror module is clamped and is driven by stick mirror clamping slider and is axially moveable.
In addition, stick mirror module can also be fixed on the stick mirror support that fixing axle rotates, is driven and rotated by stick mirror support
To between light source and light hole.
Optimally, lens may be set to be cylindrical mirror, by adjusting the focus level of the Focussing light of cylindrical mirror.
Further, cylindrical mirror is set as two, and lens are set as cylindrical mirror, changes light by the movement of cylindrical mirror position
Line focus degree is to change fan angle size.Cylindrical mirror is set as two, and two cylindrical mirrors are set as piano convex cylindrical lens, and two flat
The plane of convex cylindrical lens is opposite, and the distance between two piano convex cylindrical lens are adjustable.
In addition, cylindrical mirror be set as the adjustable stick mirror of focus level or cylindrical mirror such as mechanical pressure formula liquid cylindrical mirror or
Person's voltage regulation type liquid cylindrical mirror.
A kind of laser level provided by the present invention, has the advantage that
One, lens are made of the lens module of two or more refractive index, and the position of every kind of lens module is all adjustable to
Between light hole and light source, since lens module is respectively provided with different refractive index, so each lens module is adjusted to out light
When between hole and light source, point hot spot beats the laser line light source that different subtended angles will be obtained when on the stick mirror of different refractivity,
Laser level apply it is different apart from when select different fan angles, select lesser fan angle to make when especially more remote bright
Degree improves；Lesser fan angle can be selected to improve brightness according to the actual situation when under brighter environment using laser rays mould group.
Two, lens can be set to stick mirror, and stick mirror module is set as the stick mirror module of two or more refractive index, stick mirror module
It is clamped and is driven by stick mirror clamping slider and be axially moveable, when needing the stick mirror of which refractive index, so that it may control rod mirror folder
Sliding block is held to arrive between light source and light hole axially movable.
Three, cylindrical mirror is set as two, and lens are set as cylindrical mirror, changes light focusing by the movement of cylindrical mirror position
Degree is to change fan angle size.Cylindrical mirror is set as two, and two cylindrical mirrors are set as piano convex cylindrical lens, two piano convex cylindricals
The plane of lens is opposite, and the distance between two piano convex cylindrical lens are adjustable.As shown above, point light source is placed in parallel through two
Cylindrical mirror.Two cylindrical mirrors are assemblied in 12 by 13, and wherein 10-2 is fixed, and 10-1 can horizontally slip in 12, the position 10-1
The linear light spot of different degrees of divergence is not corresponded to simultaneously.10-1 tune is fixed by 14 when suitable position.
The subtended angle of laser level of the invention is adjustable, can be suitble to the application of various varying environments, has widened and has swashed
The applications distances and application range of light level.
