Embodiment Construction
[0025] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.
[0026] Such as figure 1 As shown, a conveniently adjustable high-precision optical level includes a base 2, a level body 2 connected to the upper surface of the base through a vertical axis perpendicular to the upper surface of the base, and a connecting bottom plate arranged at the lower part of the base 3. A telescope for measurement is installed in the level body, and a micro-inclined screw 5 for fine adjustment is also required on the level body. At the same time, a tube level 4 parallel to the collimating axis of the telescope is set on one side of the level body. To monitor the parallelism when fine-tuning the program. In order to complete the initial adjustment procedure quickly and conveniently, such as figure 2 , image 3 As shown, we can set a spherical cavity 31 at the center of the connecting base plate. The upper and lower side...

The invention discloses a high-precision optical level convenient for adjustment. The optical level comprises a base, a level body and a connecting bottom plate, wherein a tubular level and a tilting screw are arranged on the level body; a spherical cavity is formed in the connecting bottom plate; two placing grooves tangent to the spherical cavity are formed in the upper surface of the connecting bottom plate; a disk-like floating block is arranged in and fits with the spherical cavity; an oscillating rod passes through the center of the floating block and is vertically connected to the lower surface of the base by a thread; a stop nut and a spacing ring are arranged at the parts, at the upper and lower sides of the floating block, of the oscillating rod respectively; a control hammer and a transparent spherical shell are arranged at the lower end of the oscillating rod; a cross centering scale is arranged at the lower part in the spherical shell; a ball coinciding with a cross point of the centering scale is arranged in the spherical shell; at least three adjusting screws are arranged on the edge of the upper surface of the connecting bottom plate; the upper ends of the adjusting screws abut against the upper surface of the base. The optical level can rapidly complete a levelness initial adjustment procedure and has higher levelness when a sight axisworks.
Description
technical field [0001] The invention relates to a level, in particular to a high-precision optical level which is convenient for adjusting the levelness of the collimation axis. Background technique [0002] Leveling devices are mainly used to measure the height of a certain point or the height difference between two points in construction and other projects. Existing optical level measuring devices usually consist of a level and two leveling staffs. The level mainly includes a base connected to a tripod, a body rotatably connected to the base through a vertical shaft, and a The telescope, which is composed of objective lens, eyepiece, alignment lens and reticle, etc., is also equipped with a corresponding leveling structure on the body, so that the collimation axis of the telescope can be adjusted to a horizontal state during measurement. The leveling structure mainly includes a circular level set on the body to indicate whether the vertical axis is vertical, a tube level ...
