Describe the preferred forms of the utility model handlebar with reference to the accompanying drawings in detail.

As shown in Figure 1, bicycle handle bar of the present utility model comprises frame parts 1, grip member 2 with they are connected registration device 3 with what the mode of position adjustable at any time was fixed together.Frame parts 1 are had transverse tube 11 and the standpipe 12 of captiveing joint with it, and they all are known.Grip member 2 has Handle cover 21 and brake lever 22, and brake lever 22 is known.

As depicted in figs. 1 and 2, connect registration device 3 and comprise the end junction 31 that adopts welding or thread connecting mode and transverse tube 11 to be fixedly linked, the plug 32 that adopts thread connecting mode and Handle cover 21 to be fixedly linked, and bolt 33.

As shown in Figure 2, end junction 31 has tapered segment 311 and forms the disc part 312 of one with it.Disc part 312 has a centre hole 313.On the excircle of disc part 312, have several vertical slots 314.

Plug 32 has a horizontal centre hole 321 and the horizontal slot 322 of the disc the held part 312 that is communicated with this hole.The part that plug 32 has horizontal slot 322 has a hole 323.The part that hole 323 is positioned at above the horizontal slot 322 is a unthreaded hole, and being positioned at horizontal slot 322 following parts is tapped bore.Bolt 33 is rotatably connected to end junction 31 and plug 32 together by hole 323 and hole 313.

Plug 32 and transverse tube 11 form by corresponding screw thread removablely captives joint.

Connect registration device 3 and also comprise turning set 34, sliding sleeve 35, gland 36, locating dowel pin 37 and the spring 38 that is contained in the Handle cover 21.

As shown in Figure 3, the inwall of Handle cover 21 has the capable boss 211 of annulus.On the inwall of the Handle cover 21 adjacent, form a plurality of deep trouths 212 and shallow slot 213 with boss 211.Between adjacent deep trouth 212 and shallow slot 213, raised line 215 is arranged.The surface of the surface of raised line 215 and boss 211 is on the same face of cylinder.The top of raised line 215 has inclined-plane 214 and inclined-plane 218.

As shown in Figure 4, turning set 34 has big garden post part 341 and little garden post part 342.One end of big garden post part 341 has garden column flange 344.There is raised line 343 on the surface of big garden post part 341.The outside face of flange 344 and raised line 343 is on the same face of cylinder.Signal expansion as turning set 34 is shown in Figure 5, and in the adjacent regions of big column part 341 and small column part 342, big garden post part 341 has sawtooth 345.As shown in Figure 4, turning set 34 has the logical sky of stepped central.

As shown in Figure 6, the centre portion of sliding sleeve 35 has flange 351.One end of sliding sleeve 35 has a plurality of raised lines 352.Expansion as sliding sleeve 35 is shown in Figure 7, the end of an end of sliding sleeve 35 have can with sawtooth 345 ingear sawtooth 353.As shown in Figure 6, sliding sleeve 35 has centre hole.

As shown in Figure 2, turning set 34, sliding sleeve 35, gland 36, locating dowel pin 37 and spring 38 are positioned at Handle cover 21.The boss 211 of Handle cover 21 is supporting sliding sleeve 35.The raised line 352 of sliding sleeve 35 enters in the shallow slot 213 of Handle cover 21.The raised line 343 of turning set 34 enters in the deep trouth 212 of Handle cover 21.The thick portion 371 of locating dowel pin 37 stretches in the big ladder centre hole of turning set 34, and thin portion 372 stretches in the centre hole 321 of plug 32.Spring 38 is enclosed within the thin portion 372 of locating dowel pin 37, between the thick portion 371 of plug 32 and locating dowel pin 37.One end of gland 36 stretches in the Handle cover 21, is pressed on the flange 351 of sliding sleeve 35.

As shown in Figures 2 and 3, an end of Handle cover 21 has shoulder 216, is used for together known brake lever 22 being rotatably mounted to Handle cover 21 with plug 32.

As shown in Figure 3, on the surface of the end that shoulder 216 is arranged of Handle cover 21, be provided with a plurality of arc pits 217.As shown in Figure 2, will there be the screw 221 of a blind hole to be installed on the brake lever 22 by being threaded.One spring 222 that is contained in screw 221 blind holes is pressed in a ball 223 on the arc pit 217, brake lever 22 is fixed on a certain position of Handle cover 21.When needs change this position, as long as firmly rotate brake lever 22, at this moment, move on ball 223 is stressed, break away from the arc pit, rotate with brake lever 22, spring 222 is compressed.When ball 223 turn to another arc pit 217 above the time, be subjected to the pressure of spring 222 to enter this arc pit 217, brake lever 22 is fixed on the another location of Handle cover 21.

The locating dowel pin 37 of connection registration device 3 shown in Figure 2 and the relative position of the disc part 312 of end junction 31, being Handle cover 21 can be around the position of the rotational of centre hole 313 with plug 32, at this moment, the top of the thin portion 372 of locating dowel pin 37 does not enter in the vertical slot 314 of disc part 312, and the sawtooth 345 of turning set 34 is in the engagement shown in the label 9 with the sawtooth 353 of sliding sleeve 35.When forwarding Handle cover 21 to a certain position, and need be fixed on this position the time, as long as push gland 36, under the promotion of sliding sleeve 35 and turning set 34, locating dowel pin 37 compression springs 38 stretch out forward, and the top of thin portion 372 enters vertical slot 314.At this moment, the point of the sawtooth 345 of turning set 34 arrives the inclined-plane 214 of

Handle cover

21, and 214 downslides of inclined-plane, edge are rotated on the limit, because of the diameter on the face of cylinder at raised line 343 places of turning set 34 internal diameter greater than the periphery at shallow slot 213 places of Handle cover 21, raised line 343 can not enter shallow slot 213, so turning set 34 214 glides very that small distance just stops along the inclined-plane, thereby, the top of the thin portion 372 of locating dowel pin 37 still in vertical slot 314, thereby grip member 2 is fixed on this position.

When needs are regulated the position of Handle cover 21, as long as once more by giving as security gland 36, the point of the sawtooth 345 of turning set 34 will arrive other inclined-

plane

218, and 218 downslides of inclined-plane, edge are rotated on the limit, because of the diameter on the face of cylinder at raised line 343 places of turning set 34 internal diameter less than the deep trouth 212 place peripheries of Handle cover 21, raised line 343 can enter deep trouth 212, the big distance so turning set 34 can glide, thereby, locating dowel pin 37 withdrawal backward under the elastic force of spring 38 promotes, the top of thin portion 372 breaks away from vertical slot 314, thereby can freely regulate the position of grip member 2.

Handle cover and another embodiment that is connected registration device as shown in Figure 8, among the figure, Handle cover 51 is similar to into Handle cover shown in Figure 2 21, the difference of the two is that the inside face of Handle cover 51 does not have boss, two ends, the left and right sides all have negative thread.

As shown in Figure 8, in Handle cover 51, only be loaded on locating dowel pin 61 and the spring 38 that an end has bolt arrangement.Adopt this structure, as long as locating dowel pin 61 is turned a little, the top of its thin portion just can enter or withdraw from the vertical slot 314 of disc part 312 shown in Figure 2, realizes the position adjustments and the stationkeeping of grip member 2.

In the embodiment shown in fig. 8, spring 38 can be set
