Abstract

The invention provides a horizontal rotary locking mechanism for an adjustment-free handle of a driver seat, comprising a locating plate and a coil spring lock, wherein the locating plate is connected to a support cylinder below the driver seat; the coil spring lock is connected to the locating plate opposite to the rotary upper part of the driver seat; a plurality of grooves are arranged on the periphery of the locating plate; and the coil spring clock is provided with contact wheels matched with the groves on the locating plate. The mechanism provided by the invention is convenient, exact for locating and locking, safe and reliable.

Description

Technical field: [0001] The present invention relates to a rotation locking mechanism, in particular to a horizontal rotation locking mechanism without an adjustment handle for a driver's seat. Background technique: [0002] In foreign countries, there are always requirements in the driver's seat of the subway: the driver's seat can be rotated horizontally without adjusting the handle and can be automatically locked at the required angle. Faced with this requirement, friction plates and conical rotating resistance discs are often used. It is very inconvenient to use and has a short service life. Invention content: [0003] The object of the present invention is to overcome the above disadvantages and provide a horizontal rotation locking mechanism with no adjustment handle for the driver's seat that is easy to use, accurate in positioning and locking, safe and reliable. [0004] The purpose of the present invention is achieved like this: [0005] The horizontal rotation...
