Tripod supporting leg telescopic opening mechanism and adjusting method thereof

Abstract

The invention discloses a tripod supporting leg telescopic opening mechanism and an adjusting method thereof, and belongs to the field of tripods. The tripod supporting leg telescopic opening mechanism comprises a supporting column and three sets of supporting legs, the supporting column is of a hollow structure, a platform is arranged on the upper portion of the supporting column, a worm and gearmechanism and a hand wheel for driving a worm are arranged on the platform, a movable pulley traction mechanism is arranged in the supporting column, and drives a sliding sleeve hoop to move to control the three sets of supporting legs to be opened or shrink, structural design is simple, and operation is flexible and convenient; and each supporting leg comprises a fixed supporting leg pipe, a telescopic supporting leg pipe and a controllable gas spring, the controllable gas springs are used for controlling the telescopic lengths of the supporting legs, operation is easy, and the bearing capacity of the tripod is improved. According to the tripod supporting leg telescopic opening mechanism and the adjusting method thereof, the opening and telescopic operation of the tripod is very simple,an operator does not need to bow to carry out operation, and physical labor of the operator is reduced.

Description

technical field [0001] The invention relates to a tripod for placing cameras, video cameras, three-dimensional scanning equipment, surveying and mapping equipment, etc., more specifically, to a tripod outrigger telescopic expansion mechanism and its adjustment method. Background technique [0002] In the fields of photography, videography, three-dimensional scanning and mapping, tripods are often used to support and fix corresponding instruments and equipment. At present, such tripods are very common in the market, and they can usually be folded for easy portability. However, most of the existing tripods are manually adjusted, and the brackets are locked and fixed by rotating bolts, which is very inconvenient to operate and labor-intensive. The strength is also greater. [0003] For example, China Patent No. ZL200810211160.5, the date of authorization announcement is September 5, 2012, and the name of the invention is: a stent expander and a device including the expander an...

AI Technical Summary

Problems solved by technology

[0005] The purpose of the present invention is to overcome the shortcomings of existing tripods such as troublesome folding and telescopic adjustment operations and complex structures, and to provide a tripod outrigger telescopic expansion mechanism and its adjustment method. Adopting the technical scheme of the present invention, the expansion action of the tripod It is realized by the cooperation of the sheave with the traction rope and the movable pulley, and the worm gear mechanism driven by the hand wheel is used to drive the sheave to rotate, so that the outriggers can be easily adjusted to a suitable opening angle, the structure design is simple, and the operation is flexible and convenient; The telescopic action of the frame uses the controllable gas spring to control the telescopic length of the legs, which is not only easy to operate, but also improves the load-carrying capacity of the tripod; the expansion and telescopic operations of the tripod are very simple, and the operator does not need to bend down to operate, reducing manual labor of the operator
