push rods

71,73 that are oppositely arranged, pipe 72 and supporting and contactedly cutting somebody's

hair

69 or 18 in each

push rod

71 or 73 1 ends all axially penetrate with

offside driving lever

20 or 19, and the other end is provided with a lever type button 60.

Specifically, housing 3 is fixed together with outer tube 7, outer tube 7 and interior pipe 72 concentric assemblings, bearing 6 is equipped with at two ends between them, and torsion spring 8 one ends that are contained between the pipe are connected with outer tube 7, the other end is connected with interior pipe 72, the two ends of pipe 72 in two groups of steel ropes 62 are connected in by rope sheave 75, like this, when pulling moving outer tube 7, outer tube 7 can produce relative rotation under the effect of torsion spring 8 and housing 3 with interior pipe 72, thereby realizes the folding and unfolding of steel rope 62.The fluted disc 14 of denture clutch can endwisely slip in outer tube 7 by feather key 12, have groove in fluted disc 14 inboards, driving lever 20 wherein is housed, driving lever 20 can be managed in vertical in the plane of 72 axis and be rotated, endwisely slip in the waist shape slide opening 721 that this driving lever 20 can axially be opened on interior pipe 72 walls again, can not drive fluted disc 14 rotations when driving lever 20 rotates along with interior pipe 72 like this, endwisely slip but can drive fluted disc 14; Manage on 72 in the fluted disc 13 of denture clutch is contained in, in fluted disc 13 internal vertical, in the plane of pipe 72 axis driving lever 19 is housed, driving lever 19 can not relatively rotate with fluted disc 13 in this plane, endwisely slip in the waist shape slide opening 721 that pipe 72 also can axially be opened on interior pipe 72 walls in driving lever 19 radially passed again, but fluted disc 13 can not relatively rotate with interior pipe 72, fluted disc 13 endwisely slips and circumference rotates thereby driving lever 19 drives only, fluted disc 13 left sides be equipped be fixed in the back-up ring 9 of pipe on 72, between fluted disc 13 and the back-up ring 9 reseting pressuring spring 10 is housed, cutting somebody's hair 69 and cut somebody's hair reseting pressuring spring 68 also is housed between 18, reseting pressuring spring 68 cuts somebody's hair 69, cut somebody's hair and 69 drive driving levers 20, driving lever 20 is stirred fluted disc 14, fluted disc 13 meshes together under the thrust of reseting pressuring spring 68 and reseting pressuring spring 10 with fluted disc 14 like this, make outer tube 7 and interior pipe 72 on a certain direction, can not have and relatively rotate (annotate: the fluted disc tooth form of denture clutch is a helix), this direction is the direction that steel rope 62 is decontroled, it is that outer tube 7 and interior pipe 72 are relatively rotated towards other direction that torsion spring 8 releases energy, and this direction is the direction that steel rope 62 is rolled; When pressing lever type button 60, lever type button 60 rotates around little axle 61, little axle 61 is installed on the housing 3, the horizontal projection end of lever type button 60 just promotes long push rod 71 or short push rod 73 like this, long push rod 71 or short push rod 73 cut somebody's hair 69 or cut somebody's hair 18 again, cut somebody's hair 69 or cut somebody's hair and 18 promote driving lever 20 or driving lever 19 again, driving lever 20 or driving lever 19 promote fluted disc 14 or fluted disc 13 again, under the reseting elasticity that overcomes stage clip 68 and stage clip 10, wherein a

fluted disc

14 or 13 is removed, such two

fluted discs

14,13 no longer mesh, and outer tube 7 can relatively rotate with interior pipe 72.Cut somebody's

hair

69 and 18 the end of cutting somebody's hair in conjunction with being the form that is similar to big pipe box tubule, two driving levers 19,20 are space crossed setting, cut somebody's

hair

69 and 18 ends of cutting somebody's hair have slot corresponding, can get out of the way the driving lever that is adjacent, and promote another push rod (69 pushing bars 20 of promptly cutting somebody's hair, the 18 pushing bars 19 of cutting somebody's hair), and long cut somebody's hair 69 and cut somebody's hair 18 with long push rod 71 or lack between the push rod 73 and can relatively rotate, can not influence and cut somebody's

hair

69 and 18 the rotation of cutting somebody's hair because long push rod 71 or short push rod 73 can not rotate. also be provided with circlip 70 in the inside, two ends of interior pipe 72, be used to limit the position of long push rod 71 or short push rod 73, from operation, hand is pressed lever type button 60 rear tooth disks and is separated, because outer tube 7 can relatively rotate with interior pipe 72, make that steel rope 62 can free folding and unfolding, handle can raise or descend like this, behind a certain height, trip lever formula button 60, under the reset response of

stage clip

10 or 68, denture clutch closes, handle no longer descends and is parked in a certain height (annotating: produce a pulling force during people's handle downwards naturally), when staff was decontroled handle, because the rope sheave 75 on the interior pipe 72 is rolled steel rope 62, handle will rise and return to initial eminence.

The end of two groups of steel ropes 62 among Fig. 1 is walked around the cross bar of vehicle, again with the drop-down back of the end of steel rope 62 termination and steel rope 62 force togethers of compacting joint 63 with steel rope 62, thereby is connected on the cross bar.And in housing 3 inside audio player, radio receiver, bluetooth outdevice or infrared outdevice 64 and loud speaker 74 are housed, to increase the commerciality of handle.

Fig. 4 is the car body top top ceiling that steel rope 62 can directly be connected in vehicle.

Fig. 5 is that steel rope 62 can be connected with cross bar 100 by the mode of beating button.

Fig. 6 is that the upper end of steel rope 62 also is provided with the fag end height adjustment mechanism, link to each other with cross bar 100 by the fag end height adjustment mechanism, establish housing 77, screw 76 and the columniform nut 66 of guide groove 78 in comprising, housing is connected on the cross bar 100 of public transit vehicle by steel disc 65; Screw 76 lower ends are stretched in the guide groove 78 of housing 77, and cooperate with housing 77 axis holes; Nut 66 is enclosed within on the screw 76 and is located in the guide groove 78; The upper end of steel rope 62 is overlapped on the nut 66 after on the screw 76 again.Can make barrel nut 66 move by turning screw 76, thereby drive moving of steel rope 62, to reach the purpose of regulating steel rope 62 end height along the guide groove 78 of housing 77.

Fig. 7 is more comfortable in order to make that the handle pull-up comes, and steel rope 62 is connected on the crossbeam 80 that is contained on the public transit vehicle cross bar 100, and this crossbeam 80 is hinged with the cross bar 100 of vehicle.Certainly, the fag end height adjustment mechanism of Fig. 6 also can be connected on the crossbeam 80.

In sum, public transit vehicle handle of the present utility model can be by regulating the passenger's needs that highly satisfy various heights, and can automatically restore to certain altitude again and can when the passenger walks about, do not injured, simultaneously by more compact design design, on arranging, all meet the human engineering principle from using still fully, be a human, improve comfort and save the handle in space.

Those of ordinary skill in the art will be appreciated that, above embodiment is used for illustrating the utility model, and be not to be used as qualification of the present utility model, as long as in connotation scope of the present utility model, all will drop in claims scope of the present utility model variation, the modification of the above embodiment.
