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

Abstract

The invention relates to a lifting and swiveling structure, which comprises a pulling part (6), steel balls (7), a steel ball-locking disc (8), a pedestal sleeve (9) and a steel ball-locking sleeve (10); the pulling part (6) is connected with the steel ball-locking disc (8), and the pedestal sleeve (9) is sleeved on the steel ball-locking sleeve (10); holes (91) matched with the steel balls (7) are arranged on a plurality of levels of the pedestal sleeve (9); the steel ball-locking disc (8) is arranged in the steel ball-locking sleeve (10), the steel balls (7) are arranged on a slope (81) of the steel ball-locking disc (8), the lower part of the steel ball-locking sleeve (10) is provided with holes (101) matched with the steel balls (7), the holes (101) are positioned on the same level, and the upper part of the steel ball-locking disc (8) is provided with a groove (82).

Description

technical field [0001] The invention relates to a 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. Although it has...
