Brief description
Fig. 1 is the front view of first embodiment of the invention；
Fig. 2 is the sectional view of first embodiment of the invention；
Fig. 3 is the front view of second embodiment of the invention；
Fig. 4 is the sectional view of second embodiment of the invention.
Specific embodiment
As shown in Figure 1 and Figure 2, it is first embodiment that the present invention is a kind of bus pull ring, it includes fixes sleeve 1, handss
Hold portion 2, lever 3, sleeve spring 4, guide spring post 5, back-moving spring 6 and fixing device 7.
The described top of hand grip portion 2 and fixes sleeve 1 gap connect together and are provided with sleeve spring 4 between the two,
The bottom of hand grip portion 2 and lever 3, in the presence of guide spring post 5, connect and pass through fixing device 7, are formed fixing and launch
State, fixing device 7 is arranged in hand grip portion 2.
Described fixing device 7 include six rollers 711,712,713,714,715,716, suspender belt 72, fastener 73.Described
Sleeve spring 4 upper end be fixed in fixes sleeve 1, the lower end of sleeve spring 4 connects two rollers 711,713, remaining roller
Be rotatably mounted in hand grip portion, suspender belt around being connected between six rollers 711,712,713,714,715,716, suspender belt 72
Through the gap hand grip portion 2 bottom and lever 3 and this section of suspender belt 72 is between roller 715,716, in hand grip portion 2 in stage casing
On bottom place relative with lever 3 be provided with can fastener 73 on suspender belt 72 for the holding, this fastener 73 is more sharp columnar projections
Thing, e.g., triangle cylinder.
Described guide spring post 5 is made up of guide pillar 51 and guide pin bushing 52.Described guide pin bushing 52 is fixed in hand grip portion 2, leads
Post 51 is fixed on lever 3；Described back-moving spring 6 is compression spring, and back-moving spring 6 is socketed on guide spring post 5 and multiple
The two ends of position spring 6 act against on hand grip portion 2 and lever 3 respectively.In the present embodiment, guide spring post 5 has two sets, respectively position
Two ends in lever 3.
The operation principle of the present embodiment：
Described sleeve spring 4 is issued to, on roller 711 and roller 713, the mesh controlling suspender belt overhang by controlling
's.Described back-moving spring 6 controls the playback of lever 3.When passenger uses this bus pull ring, four refer to the sky through hand grip portion 2
Gap, when pulling down, the pulling force effect lower sleeve spring 4 in handss will be in extended state, and because suspender belt 72 stretches out, fixes sleeve 1 becomes
Long, when passenger's sensation is highly suitable for, with 3 one-tenth fist shapes of palm when held lever, because the grip of passenger is more than back-moving spring 6
Elastic force, back-moving spring 6 is compressed, and lever 3 rises and presses on fastener 73 by suspender belt 72, and the length of suspender belt 72 will no longer change
Become, the height of fixes sleeve 1 is fixed and bus pull ring is in stationary state.Above-mentioned sling design collapsing length in 0cm-20cm,
So that the different crowd of height uses.After passenger leaves, under the effect of back-moving spring 6, lever 3 will return automatically
Position, suspender belt 72 is no longer left fastener 73 by the pressing of lever 3, and suspender belt 72 can freely stretch.Again due to the return of sleeve spring 4
Effect, roller 711,713 rises suspender belt 72 and starts to reclaim, and fixes sleeve 1 is shunk, and hand grip portion 2 returns to original height.
As shown in Figure 3, Figure 4, be second embodiment that the present invention is a kind of bus pull ring, it include fixes sleeve 1 ',
Hand grip portion 2 ', lever 3 ', sleeve spring 4 ', guide spring post 5 ', back-moving spring 6 ' and fixing device 7 '.
The top of described hand grip portion 2 ' and fixes sleeve 1 ' gap connect together and are provided with sleeve spring between the two
4 ', the upper end of this sleeve spring 4 ' is connected to the lower end of fixes sleeve 1 ', and 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 fixing device 7 ' formation to be fixed and deployed condition, and fixing device 7 ' is arranged on
In hand grip portion 2 '.It is provided with guide spring post 5 ' between hand grip portion 2 ' and lever 3 ', back-moving spring 6 ' is socketed in guide spring post
On 5 '.
Described fixing device 7 ' includes pull bar 71 ', wedge block 72 ', sliding block spring 73 ', multiple rectangular teeth 74 '.Institute
The multiple rectangular teeths 74 ' stated are along the length direction of fixes sleeve 1 ', interval setting fixes sleeve 1 ' inner chamber, interior in hand grip portion 2 '
Chamber is radially provided with slide rail 11 ' and relative with the tooth mouth of rectangular teeth 74 '.The outer end of described wedge block 72 ' is inclined-plane, its cunning
It is connected on slide rail 11 ', the two ends of sliding block spring 73 ' act against on wedge block 72 ' and the internal chamber wall of hand grip portion 2 ' respectively.Described
Pull bar 71 ' top be located in fixes sleeve 1 ', pull bar 71 ' upper end is provided with wedge 711 ', the inclined-plane of this wedge 711 '
Relative with the inclined-plane of wedge block 72 ', the lower end of pull bar 71 ' is connected with lever 3 '.
The operation principle of the present embodiment：
Described sliding block spring 73 ' is responsible for the return of wedge block 72 ', and back-moving spring 6 ' is responsible for lever 3 ' and pull bar 71 '
Return.When passenger is when using this present invention, handss pull down, and fixes sleeve 1 ' is stretched out.When passenger's sensation is highly suitable for, use
Palm when held lever 3 ' becomes fist shape, and because the grip of passenger is more than the elastic force of back-moving spring 6 ', back-moving spring 6 ' is compressed, and holds
Handle 3 ' drives pull bar 71 ' to move downward, and the wedge 711 ' on pull bar 71 ' top also moves downward, and extruding wedge block 72 ' leads to
To left movement in wedge block 72 ' in rail 11 ', snap in the gap of rectangular teeth 74 ', the height of fixes sleeve 1 ' is fixed and public
Draw ring is handed over to be in stationary state.Above-mentioned fixes sleeve 1 ' design collapsing length is in 0cm-15cm, so that the different people of height
Group uses.After passenger leaves, under the effect of back-moving spring 6 ', lever 3 ' and pull bar 71 ' are by self-return, wedge block
72 ' also move right self-return in the presence of sliding block spring 73 ', and fixes sleeve 1 ' is received in the presence of sleeve spring 4 '
Contracting, the present invention returns to original height.
The emphasis of the present invention is that：Hand grip portion is connected together with fixes sleeve gap, between the two can relative play.
The above, only present pre-ferred embodiments, therefore can not with this limit the present invention enforcement scope, that is, according to
