Description

Pointer leveling tripod

Technical field

The invention belongs to electronic devices structure technical field, particularly one and be used for installing photoelectric device, precision is temperature influence, the fast simple pointer leveling tripod of adjusting not.

Background technique

The known tripod attachment face indicating device parallel with horizontal plane is vacuole leveling instrument, and majority does not have WidFin device, has the tripod opening direction of Universal stand device upward.Therefore there is following shortcoming in this type of tripod: the in the situation that of subzero 40 °, vacuole leveling instrument precision can obviously reduce, vacuole leveling instrument is contained on equipment attachment face, equipment frame on tripod after, for the large equipment of weight, after tripod leveling, again equipment is loaded onto, attachment face level may change and can not observe and adjust in time, opening direction Universal stand device is upward as under severse weather or environment in the wild, sand dust and silt easily enter and accumulation therein, as cleaning not in time, can impact use next time, attachment face horizontal adjustemt difficulty, needed time is long.

Summary of the invention

The object of the present invention is to provide a kind of pointer leveling tripod, leveling precision not temperature influence, adjusting is simple fast, meets military environment usage requirement.

The technological scheme that realizes the object of the invention is: a kind of pointer leveling tripod, comprise pedestal and length-adjustable three supporting legs for erection unit, every supporting leg comprises interior bar and the outer bar that is socketed in interior bar outside, the attachment face of described pedestal is regular hexagon, six sides adjacent with pedestal attachment face are all vertical with described attachment face, on the side of three spaces in described six sides, be provided with leveling indicating device, this leveling indicating device comprises pointer and hanging shaft, described pointer is provided with the suppending hole that departs from center of gravity, the sensing of described pointer is positioned on the elongation line of suppending hole center and pointer center of gravity, in the side that is provided with leveling indicating device, be provided with index line, the elongation line of this index line is vertical with the intersection of attachment face by Qie Yugai side, hanging shaft center.

Principle of the present invention is: utilize plumb line perpendicular to horizontal plane and two intersecting straight lines, to determine the principle of a plane, tripod mounting plane is designed to regular hexagon structure, with its intersect six lateral vertical in mounting plane, on three sides that are separated by six sides, plumb line pointer is installed, by stretching after the preliminary leveling tripod of interior bar length, the outer bar of rotation utilizes screw thread to finely tune tripod again, when three pointers point to leveling groove simultaneously in pointer, represents tripod leveling.

Compared with prior art, its remarkable advantage is in the present invention:

1, leveling precision is temperature influence not: adopt metal finger to show leveling result, show and compare with conventional bubble Universal leveling, precision is temperature influence not;

2, regulate fast simply: groove pointer is arranged on the side of attachment face, equipment is convenient observation and fast leveling after installing, and applicable field operations needs, can set up use on various landform, ground.

Below in conjunction with accompanying drawing, the present invention is described in further detail.
