Embodiment Construction

[0021] Below in conjunction with accompanying drawing and preferred embodiment the present invention is described in further detail:

[0022] Such as figure 1 As shown, a rigid-flexible adjustable bus pull ring includes an upper fixed component I, a lower movable component II, and a rigid-flexible adjustment component III; the upper fixed component I is fixed relative to the horizontal bar 1; the upper fixed component I It cooperates with the lower movable component II to form a rotating pair through spherical cooperation; the rigidity-flexible adjustment component III slides in the cavity of the upper fixed component I and the lower movable component II through the compression and reset of the spring.

[0023] Such as figure 2 with Figure 4 As shown, the upper fixing assembly I includes two fixing rings 2, a ball joint 3 and a fixing retaining ring 4; the two fixing rings 2 hug the horizontal bar 1 to form a shaft-hole fit, and are fixed to the horizontal bar through bolt...

Abstract

The invention relates to a flexibility-adjustable bus pull ring which comprises an upper fixed assembly, a lower movable assembly and a flexibility adjusting assembly. The upper fixed assembly is fixed relative to a horizontal cross rod, the upper fixed assembly and the lower movable assembly form a rotation pair in a spherical-surface matched mode, and the flexibility adjusting assembly slides in a cavity formed by the upper fixed assembly and the lower movable assembly by means of compressing and resetting of a spring. According to the flexibility-adjustable bus pull ring, a passenger can conduct real-time adjusting on the flexibility of the pull ring according to the needs of his / her own, the pull ring automatically restores to the flexible state after the passenger leaves, and the defect that the rigidity of an existing bus pull ring is insufficient is avoided.

Description

technical field [0001] The invention relates to a bus pull ring with adjustable rigidity and flexibility, which is used in bus or subway carriages. Background technique [0002] The bus is a common means of transportation for people's daily trips, but the number of seats on the bus often cannot meet the needs of passengers, so there must be some passengers who can only stand. In order to make it easier for passengers without seats to stand firmly, a crossbar is generally provided in the bus, and a pull ring for passengers to hold is suspended on the cross rod. The staff standing in the compartment grasps the pull ring to maintain balance, so as not to fall. Nylon straps are mostly used for flexible connections in current bus pull rings. However, during the driving process of the bus, whenever it stops, starts, turns, or brakes suddenly, due to the existence of inertia and the soft connection of the pull ring, passengers who are standing and grabbing the pull ring are not ea...
