An engineering surveying instrument

Abstract

The invention discloses an engineering surveying instrument and a lens pollution prevention machine tool for machining the surveying instrument. A surveying instrument is fixedly connected to the middle of the top end of the triangular bottom plate. A splicing mechanism is rotationally connected to the edge part of one side of the triangular bottom plate. The splicing mechanism comprises a connecting rotating block, a middle connecting square block, a side connecting square block, a buckle square box, an installation guide plate, a guide sliding rod, a sliding clamping block, a reset spring, adriving pin, a take-up reel, a limiting clamping block, a rectangular storage groove, a buckle groove, a triangular middle block and a limiting rubber pad. The side connecting square blocks are manually pulled to be far away from the triangular middle block. After the side surfaces of the middle connecting square block and the side connecting square blocks are parallel, rotation is stopped. Therefore, the surveying instrument support is deformed into the flat plate type from the cylindrical shape, the surveying instrument support can effectively utilize the storage space in the storage process, meanwhile, the flat plate type structure is more stable, the support is effectively prevented from shaking and rolling in the carrying process, and the use experience of the side surveying instrument is improved.

Description

technical field [0001] The invention relates to the technical field of surveying and mapping instruments, in particular to an engineering surveying and mapping instrument. Background technique [0002] Surveying and mapping instruments are instruments and devices designed and manufactured for surveying and mapping operations such as data collection, processing, and output. Conventional surveying and mapping instruments include levels, theodolites, total stations, and rangefinders. The surveying and mapping instruments need to be installed in the corresponding on the bracket; [0003] However, due to the fact that the brackets used by surveying and plotting instruments on the market cannot be disassembled, they cannot be placed tightly during storage, resulting in a waste of storage space. The shape close to the cylinder makes the support easy to roll, which causes a lot of inconvenience to the use of the surveying instrument. Contents of the invention [0004] The presen...

Problems solved by technology

[0004] The present invention provides an engineering surveying and mapping instrument, which can effectively solve the problem that the support used by the surveying and mapping instrument proposed in the above background technology cannot be disassembled, so that the support of the surveying and mapping instrument cannot be placed closely during storage, resulting in a waste of storage space. During the transportation of the surveying instrument bracket, due to the shape of the bracket close to the cylinder in the storage state, the bracket is prone to roll, which reduces the user experience of the surveying instrument.
