Subway lifting ring capable of being rotationally fixed to serve as advertising board

Abstract

The invention belongs to the field of bus accessories, and particularly relates to a subway lifting ring capable of being rotationally fixed to serve as an advertising board. A sliding sleeve is arranged on a cross rod, a button bolt is arranged on a connector, when a passenger does not need the lifting ring, the lifting ring can be rotated to the upper end of the cross rod to serve as the advertising board, and the possibility that the lifting ring collides with the passenger is reduced; the space of a subway carriage is fully utilized, and the advertising area of the subway is increased; byarranging a permanent magnet block, on one hand, a connecting block and a fixing rod are firm in structure, on the other hand, the lifting ring and the fixing block are fixed to prevent the passengerfrom being collided, and the hanging ring can reset conveniently without colliding the passenger.

Description

technical field [0001] The invention belongs to the field of bus accessories, in particular to a subway suspension ring which can be rotated and fixed as a billboard. Background technique [0002] On the bus, in order to ensure the riding safety of standing passengers, there are usually fixed cross-bar type handrails and ring handrails installed on the cross-bar type handrails. [0003] In order to prevent passengers walking in the carriage from colliding with the rings and handrails, tall passengers usually directly grasp the crossbar without using the rings, and often collide with the rings, causing passengers to be injured. Rod-type handrail connection, when in use, because there is a large movable space between the ring-type handrail and the cross-bar-type handrail, the ring-type handrail can swing freely, and the stability is poor. Under the action of the handrail, the passenger will hold the handrail of the ring and shake it in the compartment greatly, and it is easy ...

[0003] In order to prevent passengers walking in the carriage from colliding with the rings and handrails, tall passengers usually directly grasp the crossbar without using the rings, and often collide with the rings, causing passengers to be injured. Rod-type handrail connection, when in use, because there is a large movable space between the ring-type handrail and the cross-bar-type handrail, the ring-type handrail can swing freely, and the stability is poor. Under the action of the handrail, the passenger will hold the handrail of the ring and shake it in the compartment, and it is easy to lose the center of gravity and fall down. The handrail of the ring has no obvious effect on keeping the passengers stable.
