Novel lifting rotation structure

Abstract

The invention discloses a novel lifting rotation structure. One end of an operating rod is fixedly connected with a handle, and the other end of the operating rod is fixedly connected with a half-moon table and a steel ball locking sleeve; the lower end of the half-moon table is provided with a locking mechanism upper cover; one end of a connecting pipe is connected with the locking mechanism upper cover, and a steel ball locking disc is fixedly sleeved at the other end of the connecting pipe; a spring is arranged in the connecting pipe, a guide mechanism is arranged in the spring, one end of the spring is connected with the locking mechanism upper cover, and the other end of the spring is connected with a pedestal; the steel ball locking disc is arranged in the steel ball locking sleeve, the slope of the steel ball locking disc is provided with steel balls, holes matched with the steel balls are formed on the lower part of the steel ball locking sleeve and positioned on the same horizontal plane, and the upper part of the steel ball locking disc is provided with a groove; a pedestal sleeve is sleeved outside the steel ball locking sleeve positioned on the lower part of the operating rod and connected with the pedestal; and multiple horizontal planes of the pedestal sleeve are provided with holes matched with the steel balls.

Description

technical field [0001] The invention relates to a new type of lifting and rotating structure, which is mostly used on the driver's and passenger's seats on aviation, ships (submarines), high-speed trains, automobiles and other vehicles for height adjustment and rotation positioning. Background technique [0002] Existing seat elevating and rotating mechanism realizes elevating and rotating mostly by the elevating rod that screw rod and nut are formed. Since the screw and nut are mainly made of metal materials, the thread on the screw is directly on the body, which is easy to wear and rust. After a long time of use, there will be phenomena such as lifting and shaking, poor rotation, and increased noise. , as the Chinese patent that the patent No. is 99229074.3, it is to change the screw thread of the swivel chair lifting rod into winding on the screw rod body with metal wire, and simultaneously the nut cover is made of wear-resistant, compressive nylon material instead.

AI Technical Summary

Problems solved by technology

Since the screw and nut are mainly made of metal materials, the thread on the screw is directly on the body, which is easy to wear and rust. After a long time of use, there will be phenomena such as lifting and shaking, poor rotation, and increased noise. , such as the Chinese patent No. 99229074.3, which changes the thread of the swivel chair lifting rod to be wound on the screw body with a metal wire, and at the same time changes the nut sleeve to be made of wear-resistant and compression-resistant nylon material.

Although it solves the above problems, it still has complex structure and unreasonable

The disadvantage of wasting materials, and the wires wound by it are easy to fall off, causing the lifting and rotation to be ineffective, and the user is inconvenient
