Abstract

The utility model relates to an adjustable-handle for bicycle. The inner end of the right and left horizontal tubes are respectively fixedly connected with short straight shafts. The short straight shafts are respectively inserted into the shaft holes which are fixedly connected with the vertical tubes of the handle-bar. A locking block which is connected with the short straight shafts by the teeth is arranged between the two short straight shafts, and the locking block can be opened. The upper parts of the two short straight shafts are also respectively sheathed with a couple of synchronous gears which are connected mutually by the teeth. The synchronous gears are used to realize the synchronous rotation of the right and left horizontal tubes. So the utility model with an adjustable and folded handle bar which has the advantages of comfortable and safe use for riders is convenient to transport and store the bicycle.

Description

Adjustable bicycle handle bar

The utility model relates to a kind of handle bar structure of bicycle, particularly a kind of adjustable bicycle handle bar's structure.

Manpower bicycles' such as bicycle, three-wheel vehicle handlebar is by transverse tube and stem are formed by connecting by fixed connection apparatus such as joints at present, when it being configured on manpower bicycles' such as bicycle, three-wheel vehicle the front forked frame, this handle bar structure has just become a kind of fixing handlebar, it can't be regulated according to the characteristics of human body, no matter cyclist's height, body weight, also how all can't handlebar be adjusted regardless of the speed by bike and the condition of road surface of riding, thereby to cyclist's fatiguability and dangerous.This in addition fixed type handlebar is one in a car not only, can't embody its characteristics of personality, the style dullness; And can not fold, in transportation, all feel inconvenience during storage.

The purpose of this utility model is in order to overcome the deficiency of above-mentioned existence, and provides a kind of structure style variable, is convenient to the adjustable bicycle handle bar that transports and preserve.

The purpose of this utility model is finished by following technical solution, it be about the medial end of two transverse tubes respectively be fixed with a short d-axis, two short d-axis are inserted in respectively in the axis hole that is fixed on the axle bed on the stem, being provided with two between two short d-axis can be by the latch segment of spreading, and latch segment combines with tooth with lacking between the d-axis.

The utility model is the interlock of two transverse tubes about realizing, is equipped with the synchronizer gear that mutual tooth connects respectively on two short d-axis.

Latch segment described in the utility model contacts with two short d-axis respectively, is mounted with an end and has dwang (or rotor wheel) camshaft between two latch segments.

Two latch segments described in the utility model can also be the wedge lock pieces, two wedge surfaces of each wedge lock piece combine with tooth with two short d-axis respectively, centre at two wedge lock pieces links to each other with screw rod, and screw rod is opposite with the thread rotary orientation of two wedge lock pieces configuration.

Fig. 1 is a structural representation of the present utility model.

Fig. 2 is the side-looking structural representation of Fig. 1.

Fig. 3 is that A-A cuts open and shows structural representation among Fig. 1.

Fig. 4 is another latch segment installing structure scheme drawing of the utility model.

Below will the utility model is further introduced: Fig. 1～Fig. 3 by accompanying drawing, on a left side transverse tube 1 and the right side respectively are welded with a short d-axis 3 to the medial end of transverse tube 2, two short d-axis 3 are inserted in respectively in the axis hole of the axle bed 5 that is fixedly connected on stem 4, the lower end is fixing with nut 6, and two short d-axis 3 can be rotated in the axis hole of axle bed 5.Be inserted in the synchronizer gear 7 that mutual tooth connects on the top of two short d-axis 3, short d-axis 3 also links to each other with tooth with synchronizer gear 7, when transverse tube rotates, just can drive another transverse tube by the transmission of synchronizer gear 7 and do corresponding rotation, thereby about realizing the synchronous rotation of transverse tube.Axle bed 5 is to be fixed on the stem 4 with screw 8, and is connected with plastic casing 9 in the fixed outside of axle bed 5, and in the above structure is included in.Being provided with two between two short d-axis 3 can be by the latch segment 10 of spreading, the arrangement direction of this two latch segment 10 is respectively with about two short d-axis 3 contact promptly with tooth to place, between this two latch segment 10, then be mounted with a camshaft 11, the one end is fixing with jump ring 12, the other end is fixed with dwang 13 (or turning cylinder), also be provided with torsion spring 14 on this camshaft 11, make camshaft 11 under the effect that does not have external force, be in a certain location status all the time, a certain location status described here is meant nature spreading two latch segments 10, make latch segment and short d-axis fit tightly the state that can not rotate.When needs are regulated, as long as pull dwang 13, make camshaft 11 rotate a position, crack it open to the tensile force of latch segment, at this moment just rotatable transverse tube is adjusted to a certain position with it after, unclamp bull stick 13, at this moment, camshaft 11 just can reposition under the effect of torsion spring 14, and camshaft 11 will continue latch segment 10 is produced thrusts, is issued to about locking the purpose of transverse tube with combining of tooth compressing the contact surface tooth.

Foregoing latch segment 10 is placed about being, another embodiment of the present utility model places before and after can being, see Fig. 4, and select wedge lock piece 10 for use, the flank of tooth of each wedge lock piece contacts with two flank of tooth of lacking on the d-axis respectively, centre at two wedge lock pieces connects with the screw rod 15 that two has the rotation direction opposite threads, and an end of screw rod 15 is fixed with runner 16.

The utility model compared with prior art, it is adjustable to have a handlebar, folding characteristics, The cyclist not only can according to the human body characteristics and by bike environment handlebar is regulated, make and ride Car the person feel comfortably cool by bike the time, and is not tired, safety again, and in transportation, during storage, Can fold, reduce the shared volume of vehicle, dispose simultaneously the bicycle of this handlebar and give the people Sensation with a kind of novelty.
