Problems solved by technology

[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.

Embodiment 1

[0023] Such as figure 1 As shown, a subway ring that can be rotated and fixed as a billboard includes a connector 1, a fixed block 2 and a ring 3, the lower end of the connector 1 is provided with a button 9, and the button 9 is fixedly connected with a spacer and a button rack 10, The button rack 10 is engaged with the gear 11, the gear 11 is engaged with the fixed rack block 12 of the sliding sleeve, and the fixed rack block 12 of the sliding sleeve is as figure 2 The rack shown is connected with the sliding sleeve through a spring, and the racks are connected by a horizontal plate, and the bottom of the horizontal plate is connected with the button through a spring. The horizontal plate is fixedly connected with a pin, and the head of the pin is The ball is convenient to move when the connector rotates, and the pin passes through the sliding sleeve 13 and is inserted into the groove of the cross bar 14 to fix the suspension ring. The upper end of the connector 1 is fixedly...

Embodiment 2

[0027] Such as Figure 4 As shown, the present embodiment is the situation when the suspension ring of embodiment 1 is used.

[0028] In this embodiment, when the passenger presses the button 9, the button rack 10 drives the sliding sleeve fixing rack block 12 through the gear 11 to pull out the latch, so that the sliding sleeve 13 can be rotated to put down the lifting ring. After the lifting ring is put down, the structure of the connector 1 is as follows: Figure 5 Shown; When the passenger pulls ring 3 as Figure 6 As shown, the fixed rod 7 drives the connecting block 6 through the mortise and tenon structure to be pulled out of the fixed block 2, and the movement of the connecting block 6 affects the sling 8 passing through the upper opening to drive the moving block 5 connected at both ends of the sling 8, and the moving block 5 is pulled out by the sling. 8 is completely pulled from the cavity of the lifting ring 3 to the cavity of the fixed block 2. Thereby, the degr...

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 ...
