Detailed description of the invention
For technological means, creation characteristic that the present invention is realized, reach object and effect is easy to understand, knot belowClose concrete diagram, further set forth the present invention.
Shown in Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5 and Fig. 6, the present invention is a kind of for adjustable three of optical survey instrumentFoot rest, comprises an instrument fixed station 1, and instrument fixed station 1 is cylindrical, and instrument fixed station 1 below is provided with fixed bar 2, fixed bar 2Below is provided with sleeve 3, and sleeve 3 is provided with adjusting handle 11 near fixed bar 2 one end, and the other end is provided with support retainer ring 4, and support is solidFixed ring 4 outer round surface are evenly provided with lug 5, and lug 5 quantity are 3, and support retainer ring 4 belows are provided with fixed mount 17, fixed mount17 lower ends are provided with retainer ring 8, and retainer ring 8 outer round surface are provided with the retainer ring lug 9 corresponding with lug 5;
In the present embodiment, also comprise the adjusting rod 10 that the support 6 that is connected with lug 5 is connected with retainer ring lug 9,Frame 6 tops are provided with work shape groove 12, in the middle of work shape groove 12, are provided with carriage, and carriage comprises outer slide 14, inner slide 15 andThe bolt 13 that connects inner and outer slider, inner slide 15 end faces are provided with inner slide lug 16, and inner slide lug 16 is connected with adjusting rod 10Connect.
In the present embodiment, lug 5 is with carriage with adjusting rod 10 and adjusting rod 10 with support 6, retainer ring lug 9Chain connection, also can select other to be rotatably connected.
The present embodiment medium-height trestle 6 one end are provided with leg 7, and leg 7 lower surfaces are provided with anti-abrasion pad (for marking), avoid leg 7When through long use, there are larger wearing and tearing, thus the service life of having improved tripod.
In sum, the present invention is evenly provided with lug at support retainer ring outer round surface, and at lug, place is connected with support,Frame upper end is provided with work shape groove, is provided with carriage in work shape groove inside, carriage comprises in outer slide, inner slide and connection,The bolt of outer slide, but be provided with inner slide lug at inner slide end face, below support retainer ring, be provided with fixed mount, fixed mountLower end is provided with retainer ring, but is provided with the retainer ring lug corresponding with lug at retainer ring outer round surface, retainer ring lug withAdjusting rod is connected, and the adjusting rod other end is connected with inner slide lug, lug and support, retainer ring lug and adjusting rod and tunePole and carriage are chain connection, thereby the carriage that is arranged at work shape groove inside of sliding regulates a tripodJust, another, be provided with adjusting handle at sleeve near fixed bar one end, thereby adjusting handle carrys out the height of control instrument positioning tableLow, and then improved the height adjustable range of tripod, thus expand the scope of application of tripod. Advantage of the present invention is:Reasonable in design, simple in structure, be skillfully constructed, height adjustable range can adapt to greatly different working environments, stability strong, useLife-span is grown, is convenient to promote.
