Three-jaw base for reinforcing and fixing optical plummet

Abstract

The invention discloses a three-jaw base for reinforcing and fixing an optical plummet. The three-jaw base comprises a positioning base body, a limiting rotating shaft is fixedly installed at the center of the top face of the positioning base body, the three-jaw base body movably connected with the positioning base body is fixedly installed at the top end of the limiting rotating shaft, three electromagnetic positioners distributed around the limiting rotating shaft at equal intervals are fixedly installed at the bottom of the three-jaw base, and photovoltaic storage batteries movably connected with the positioning base are fixedly installed on the six side faces of the three-jaw base. According to the scheme, an output end of a storage battery pack is electrically connected with an electrically-driven pulley and an electromagnetic positioner, an input end of the storage battery pack is electrically connected with a photovoltaic panel, in the working process of a device, the photovoltaic panel is used for photovoltaic conversion to charge the storage battery pack, then the storage battery pack provides electric energy for the electrically-driven pulley and the electromagnetic positioner, and the electric driving pulley drives a six-edge rotating platform and an optical plummet on the top of the six-edge rotating platform to horizontally rotate, so that the practicability and the environmental protection property of the device are improved.

Description

technical field [0001] The invention relates to the technical field of three-claw bases, more specifically, the invention relates to a three-claw base for strengthening and fixing an optical plummet. Background technique [0002] The three-claw base is an accessory widely used in various optical instruments such as surveying instruments, theodolites, total stations, and levels. Its main function is to connect and fix optical plummets. The existing optical plummets usually have the same The three-claw base is compatible with the triangular pin, and the optical plummet is docked and fixed by connecting the triangular pin at the bottom to the claw hole in the three-claw base. [0003] However, the connection between the existing optical plummet and the three-claw base is mostly directly inserted into the claw hole in the three-claw base through the triangular pin. After the three-claw base has been used for a long time, the claws in the three-claw base The hole diameter is eas...

Problems solved by technology

[0004] In order to overcome the above-mentioned defects of the prior art, the embodiment of the present invention provides a three-claw base for strengthening and fixing the optical plummet, so as to solve the problem that the connection between the existing optical plummet and the three-claw base is mostly through triangular pins It is directly plugged into the claw hole in the three-claw base. After the three-claw base is used for a long time, the aperture of the claw hole in the three-claw base is easy to wear and increase, resulting in an unstable connection between the optical plummet and the three-claw base. , so that the optical plummet is easy to loose or even fall off, which brings great inconvenience to the use of the optical plummet
