Tripod for optical surveying instrument

Abstract

The invention discloses a tripod for an optical surveying instrument. The tripod comprises an instrument fixing table and an adjustable support frame device arranged under the instrument fixing table, wherein a fixing post is arranged under the instrument fixing table, the adjustable support frame device comprises a support frame storing post and adjustable support frames uniformly distributed in the circumferential direction of the support frame storing post, adjustable support frame storing grooves are uniformly formed in the outer surface of the support frame storing post, the upper ends of the adjustable support frame storing grooves are provided with a fixing block, the upper ends of the support frame storing post is provided with a fixing sleeve, and the upper end of the fixing sleeve is provided with a fixing table regulating device. The tripod has the advantages that the adjustable support frames and the adjustable support frame storing grooves are in one-to-one correspondence, when the adjustable support frames are collected, the adjustable support frames are screwed into the adjustable support frame storing grooves, and further, the damage to the adjustable support frames by external objects in the carrying process can be avoided, so the protection performance of the adjustable support frames is improved, and meanwhile, the service life of the tripod is also prolonged.

Description

technical field [0001] The invention relates to an optical surveying instrument, in particular to a tripod for the optical surveying instrument. Background technique [0002] A tripod is a common support assembly that uses three legs to provide a stable support platform. During the use of tripods, the problems of carrying and transportation are often involved, so portability is an issue that must be paid attention to in the design of tripods. At present, the commonly used method is to design the legs of the tripod in a detachable manner, that is, to separate the legs from the tripod base during transportation and store them separately, which can save the space occupied by the tripod, but such a disassembly process Inconvenient and time consuming. Another common method is to design the legs of the tripod in a retractable way, which is flexible in operation and easy to use. However, the tripod after the telescopic tripod often contacts or collides with foreign objects during...

Problems solved by technology

At present, the commonly used method is to design the legs of the tripod in a detachable manner, that is, to separate the legs from the tripod base during transportation and store them separately, which can save the space occupied by the tripod, but such a disassembly process inconvenient and time consuming

Another common method is to design the legs of the tripod in a retractable way, which is flexible in operation and easy to use. However, the tripod after the telescopic tripod often contacts or collides with foreign objects during carrying, which in turn causes certain damage to the tripod. thereby shortening its service life
