Rotating shaft with built-in power line and rotary chair with same

Abstract

The invention relates to the field of seats, in particular to a rotating shaft with a built-in power line. The rotating shaft comprises an outer pipe and a shaft core assembly, wherein the shaft coreassembly is arranged inside the outer pipe and can rotate relative to the outer pipe; one end part of the shaft core assembly stretches out of the outer pipe for connecting a rotating member; a powerline assembly is arranged inside the shaft core assembly in a penetrating mode; the power line assembly comprises a first wiring section partially arranged inside the shaft core assembly in the penetrating mode and a second wiring section capable of being in butt joint with the first wiring section for electrification; a first wiring terminal at the end part of the first wiring section is embeddedin the shaft core assembly and synchronously rotates with the shaft core assembly, and after the first wiring terminal at the end part of the first wiring section is butted with the second wiring terminal at the upper end part of the second wiring section, the butted part of the first wiring terminal can rotate along the circumferential direction of a shaft core wire of the shaft core assembly. Through the scheme, the problem that knots are generated in the rotating process of internal circuit wiring is solved; the problem of circuit wiring of two parts rotating relative to each other throughthe rotating shaft is overcome, and a group of power supplies can be shared to supply power on the two parts.

Description

technical field [0001] The invention relates to the field of seats, in particular to a rotating shaft with a built-in power cord and a swivel chair with the rotating shaft. Background technique [0002] Seats are common daily and office supplies in life. There are many types of seats, including fixed tables and chairs (such as most dining chairs), swivel chairs and rocking chairs. It has become a very common chair in life, especially in the office, its usage rate is very high. [0003] Traditional swivel chairs generally only have the functions of height adjustment and rotation, and with the popularity of these functions, the additional functions of swivel chairs on the existing market have also increased accordingly, as disclosed in the Chinese utility model with the announcement number "CN206324500U". A multimedia innovative reclining chair with a built-in bluetooth speaker, which adds a speaker, a bluetooth speaker and a control panel to the swivel chair. In this way, t...
