Description

Technical Field

[0001] The utility model relates to the technical field of distance measuring equipment, in particular to a telescope type distance measuring instrument calibration assistant. Background Art

[0002] A telescope rangefinder is a laser rangefinder, also called a long-range laser rangefinder. The physical structure of the telescope rangefinder can be divided into two types: with and without a tripod hole. The ranging accuracy can reach 0.3m-1.0m, and the ranging range is mostly 500-3000 meters. It is mainly used for long-distance measurement in the field.

[0003] The calibration specification requires that the telescope rangefinder be calibrated on a standard length baseline field. The baseline field is composed of multiple observation piers. The specification does not specify how to set up the telescope rangefinder and target on the observation piers, and how to design the size of the target. The calibration agency needs to properly handle this according to the actual situation.

[0004] In order to solve the problem of connecting a telescope type rangefinder with a standard length baseline field during calibration, a telescope type rangefinder calibration aid is proposed. Utility Model Content

The staff first installs the rangefinder body on the top of the slider through a thread, and then twists the threaded ring to make it rotate on the outside of the threaded screw. During the rotation, the pointer on the right side of the auxiliary bar and the rangefinder body on the top are driven to rotate. Then the staff can read the angle value by reading the pointer's indication of the protractor plate. Later, during calibration, the staff can pull the rangefinder body to drive the slider to move inside the limit slide slot, and at the same time drive the conical block. Then the staff can read the movement value through the indication of the conical block. Through the design of the pointer and the protractor plate and the setting of the conical block and the rangefinder plate, the staff can quickly read the value, thereby effectively improving the practicality and solving the problem of connecting the telescope rangefinder with the standard length baseline field during calibration.

The top of the support plate 1 is located on the outside of the support column and a spirit level is fixedly installed thereon. With the setting of the adjustment component, the staff using the support plate can observe whether the support plate 1 is in a horizontal state by observing the spirit level, and then move the auxiliary rod up and down by tightening the connecting bolt, thereby adjusting the horizontal angle of the support plate 1, which effectively improves the practicality and facilitates the use of the staff.

During the rotation, the pointer on the right side of the auxiliary bar and the rangefinder body on the top are driven to rotate. Then the staff can read the angle value by reading the indication of the pointer to the angle protractor. Then, during calibration, the staff can pull the rangefinder body to drive the slider to move inside the limiting slide groove, and at the same time drive the tapered block. Then the staff can read the movement value through the indication of the tapered block. Through the design of the pointer and the angle protractor and the setting of the tapered block and the rangefinder, the staff can quickly read the value, thereby effectively improving the practicality and solving the connection problem between the telescope rangefinder and the standard length baseline field during calibration.

[0014] In the utility model, the setting of the fixing component is that during use, the staff inserts the support rod into the interior of the placement groove, and then gradually closes the fixing clamp ring by tightening the fixing bolt 2, so that the support rod can be fixed, which effectively improves the safety and stability of the support rod and facilitates the use of the staff.

[0015] In the utility model, the setting of the adjustment component allows the staff using the device to observe whether the support plate 1 is in a horizontal state by observing the level meter, and then to move the auxiliary rod up and down by screwing the connecting bolts, thereby adjusting the horizontal angle of the support plate 1, which effectively improves the practicality and facilitates the use of the staff.
