Description
Technical Field
The utility model belongs to measuring equipment especially relates to a hand-held type laser rangefinder's precision verification auxiliary device.
Background
With the increasing of the construction strength of national infrastructure, the requirements on the environment and time of measurement work are stricter and stricter, and the requirements on the precision of engineering measurement are higher and higher. The handheld range finder has important application in building and house measurement, and the measurement accuracy of the handheld range finder is directly related to the construction effect.
The hand-held laser distance measuring instrument is a portable measuring instrument which takes laser as carrier wave, takes diffuse reflection measurement of a target surface as a characteristic and measures a short-distance in space by a pulse method, a phase method and other methods, has the characteristics of light weight, small volume, simple operation, high speed, accuracy and the like, and is widely used for measuring buildings.
The conventional handheld laser range finder requires first verification, subsequent verification and verification in use, and the verification period is generally not more than one year. It has been found in practice that it is very inconvenient to determine the reference position of the hand-held rangefinder.
SUMMERY OF THE UTILITY MODEL
Make examination operation more convenient for the accurate relative position who obtains the range finding reference surface, measuring result is more accurate, the utility model provides a hand-held type laser range finder's precision examination auxiliary device.
The utility model discloses a hand-held type laser rangefinder's precision verification auxiliary device structure does: the leveling knob is installed on the base, the base is borne on the leveling knob, the connecting rod is connected with the base and the fixing platform, a screw is further arranged between the base and the fixing platform, and the fixing platform is provided with a clamping device for installing the handheld laser range finder.
Further, the number of the leveling knobs is three.
Further, the spirals include a coarse quasi-focal spiral and a fine quasi-focal spiral.
Furthermore, the connecting rod is provided with vertical displacement scale marks, and the base is provided with transverse displacement scale marks.
The utility model has the advantages of:
adopt the utility model discloses the fixed distancer of auxiliary device to the cooperation uses observation targets such as cross, can comparatively accurately obtain an observed value, compares with known accurate value again, can calculate the precision that obtains handheld distancer. The relative position of the distance measuring reference surface can be accurately obtained, so that the verification operation is more convenient and the measuring result is more accurate.
Drawings
FIG. 1 is a schematic structural view of the present invention;
fig. 2 is a side view of the present invention.
In the figure: 1-leveling knob, 2-base, 3-connecting rod, 4-fixed platform, 5-screw and 6-clamping device.
Detailed Description
The present invention will be described in further detail with reference to the accompanying drawings and specific embodiments.
Referring to fig. 1 to 2, the utility model discloses a hand-held type laser range finder's precision verification auxiliary device structure is: leveling knob 1 is installed on the base, bears base 2 above leveling knob 1, and connecting rod 3 connects base 2 and fixed platform 4, still sets up spiral 5 between base 2 and the fixed platform 4, and spiral 5 is including thick accurate burnt spiral and thin accurate burnt spiral. The fixed platform 4 is provided with a clamping device 6 for mounting the hand-held laser distance measuring instrument.
Further, three leveling knobs 1 are provided for adjusting the level of the base 2.
