Fig. 4 is the cutaway view of second embodiment of the utility model.
The specific embodiment
As shown in Figure 1 and Figure 2, be that the utility model is first embodiment of a kind of bus pull ring, it comprises fixed muffle 1, hand grip portion 2, lever 3, sleeve spring 4, guide spring post 5, retracing spring 6 and anchor fitting 7.
The top of described hand grip portion 2 and fixed muffle 1 gap connect together and are provided with sleeve spring 4 between the two, the bottom of hand grip portion 2 and lever 3 are under the effect of guide spring post 5, connect and pass through anchor fitting 7, forming state fixing and that launch, anchor fitting 7 is arranged in hand grip portion 2.
Described anchor fitting 7 comprises six rollers 711,712,713,714,715,716, suspender belt 72, fastener 73.Described sleeve spring 4 upper ends are fixed on fixed muffle 1, the lower end of sleeve spring 4 connects two rollers 711,713, all the other rollers are rotatable to be arranged in hand grip portion, suspender belt solderless wrapped connection is between six rollers 711,712,713,714,715,716, suspender belt 72 stage casings through the gap between hand grip portion 2 bottoms and lever 3 and this section of suspender belt 72 between roller 715,716, on hand grip portion 2 bottoms, being provided with lever 3 opposite positions can the fastener 73 of holding on suspender belt 72, this fastener 73 is more sharp-pointed columnar projections thing, as, triangle cylinder.
Described guide spring post 5 consists of guide pillar 51 and guide pin bushing 52.Described guide pin bushing 52 is fixed in hand grip portion 2, and guide pillar 51 is fixed on lever 3; Described retracing spring 6 is Compress Spring, and retracing spring 6 is socketed on guide spring post 5 and the two ends of retracing spring 6 lean respectively on hand grip portion 2 and lever 3.In the present embodiment, guide spring post 5 has two covers, lays respectively at the two ends of lever 3.
The principle of work of the present embodiment:
Described sleeve spring 4 is by being issued to the object of controlling suspender belt overhang on control roller 711 and roller 713.Described retracing spring 6 is controlled the playback of lever 3.When passenger uses this bus pull ring, four fingers are through the space of hand grip portion 2, pulling force effect lower sleeve spring 4 at hand while pulling down will be in extended state, because suspender belt 72 stretches out, fixed muffle 1 is elongated, when passenger's sensation is highly applicable to, with palm, hold 3 one-tenth fist shapes of lever, because passenger's grip is greater than the elastic force of retracing spring 6, retracing spring 6 is compressed, lever 3 rises suspender belt 72 is pressed on fastener 73, and the length of suspender belt 72 will no longer change, the height of fixed muffle 1 fix and bus pull ring in stationary state.Above-mentioned suspender belt design collapsing length, can be so that the different crowd of height uses at 0cm-20cm.After passenger leaves, under the effect of retracing spring 6, lever 3 is by self-return, and suspender belt 72 is no longer subject to pressing of lever 3 to leave fastener 73, and suspender belt 72 can free-extension.Due to the return effect of sleeve spring 4, roller 711,713 rising suspender belts 72 start to reclaim again, and fixed muffle 1 shrinks, and hand grip portion 2 returns to original height.
As shown in Figure 3, Figure 4, be that the utility model is a kind of second embodiment of bus pull ring, it comprises fixed muffle 1 ', hand grip portion 2 ', lever 3 ', sleeve spring 4 ', guide spring post 5 ', retracing spring 6 ' and anchor fitting 7 '.
The top of described hand grip portion 2 ' and fixed muffle 1 ' gap connect together and are provided with sleeve spring 4 ' between the two, the upper end of this sleeve spring 4 ' is connected to the lower end of fixed muffle 1 ', the lower end of sleeve spring 4 ' is connected in hand grip portion 2 ', the bottom of hand grip portion 2 ' is connected with lever 3 ' and passes through anchor fitting 7 ' formation and fix and deployed condition, and anchor fitting 7 ' is arranged in hand grip portion 2 '.Between hand grip portion 2 ' and lever 3 ', be provided with guide spring post 5 ', retracing spring 6 ' is socketed on guide spring post 5 '.
