Abstract
The invention discloses an automatic display level ruler. The level ruler comprises a support seat, wherein a swing rod with a counter weight at one end is hinged with the support seat; a laser device is arranged at the other end of the swing rod; light rays emitted by the laser device are vertical to the swing rod; a cylindrical mirror is further arranged on the support seat; after the light rays emitted by the laser device are irradiated on the cylindrical mirror, laser points are pulled by the generatrix along a cylindrical surface to form a linear light beam. The level ruler is simple in structure, small in size, low in cost, and convenient to operate; the counter weight capable of swinging freely automatically forms a plumb line while being fixed, and the direction of the plumb line is as the same as the gravity direction; the laser device is installed on the counter weight, and the laser light rays are accurately adjusted to be vertical to the gravity line, so that the light rays refracted on the cylindrical mirror are the real horizontal lines vertical to the gravity line.
Description
Technical field
The present invention relates to a kind of level meter.
Background technology
In engineering construction, house decoration and many occasions, need to, on metope or in certain construction surface, establish a level or perpendicular line.Certainly, such instrument exists, and can be laser vertical instrument or laser leveler.But above instrument is for regular, accurate construction, and its cost is high, and volume is large, and having can not popularization.
Summary of the invention
The object of this invention is to provide a kind of simple in structure, lower-cost automatic reveal competence chi.
To achieve these goals, by the following technical solutions: a kind of reveal competence chi automatically, it is characterized in that: described surveyor's staff comprises bearing, one end is hinged with swing arm and the bearing of weight, the other end of swing arm is provided with laser instrument, and light and swing arm that laser instrument sends are perpendicular, is also provided with cylindricality mirror on bearing, after the light that laser instrument sends is irradiated on cylindricality mirror, laser spots has been pulled into a linear beam along segment of a cylinder.
Described laser instrument is the laser instrument that sends cross light.
The present invention is simple in structure, volume is little, cost is low, easy to operate, in the time that the weight that can freely swing is fixing, it sets up a pedal line automatically, consistent with gravity direction.Laser instrument is contained on weight, and laser rays is through accurate adjustment, vertical with gravity vertical direction.The light reflecting on cylindricality mirror is so exactly the real horizontal line vertical with gravity vertical.
brief description of the drawings
Fig. 1 is schematic diagram of the present invention;
Fig. 2 is structural representation of the present invention.
Embodiment
Below in conjunction with the drawings and specific embodiments, the present invention will be further described.
As shown in Figure 1, a laser component A who glows, what laser instrument sent is directional light, in the time that it is mapped on a cylindrical mirror B, laser spots has been pulled into a linear beam C along segment of a cylinder.
Utilize above principle, the present invention proposes a kind of reveal competence chi automatically.
As shown in Figure 2, surveyor's staff comprises bearing 4, bearing bottom is with bracing frame 3, one end is hinged with swing arm and the bearing of weight 5, the other end of swing arm is provided with laser instrument 2, and light and swing arm that laser instrument 2 sends are perpendicular, is also provided with cylindricality mirror 1 on bearing, after the light that laser instrument sends is irradiated on cylindricality mirror, laser spots has been pulled into a linear beam along segment of a cylinder.
Laser instrument also can adopt the Laser Devices of cruciform pattern.The horizontal line showing so, perpendicular line has had.
Claims (2)
