Description

Bicycle handle angular adjustment structure

Technical field

The utility model relates to bicycle handle, is meant a kind of bicycle handle angular adjustment structure especially.

Background technology

Usually, the wheel line and the car body of bicycle rear are held in same straight line, and the front-wheel of bicycle then can be subjected to the drive of handle and swing, and then change the wheel line of front-wheel and the angle of car body, reach the purpose that makes turning of bicycle and keep the car body balance; And the handle of bicycle also has the function of assisting to keep rider's centre of body weight in addition except turning in order to control and keeping the car body balance.

As shown in Figure 1, the handle of handle 10 both sides of bicycle for grasping for the rider, mainly be to be connected with vertical tube of front fork 20, allow to keep front fork swaying direction and angle, and then reach the purpose of control turning of bicycle via both hands or one hand at the point midway that corresponds to the both sides handle; In addition, the bicycle handle that present industry is generally used always is mainly one-body molded by single tubing, and its cost is higher.

Be that angle between its both sides handle is fixing immutable structure kenel, that is to say, must deacclimatize the original design that grips angle for both hands of handle by rider oneself, with regard to driving of short time used, perhaps still can accept the incompatibility that both hands grip angle, but if need drive for a long time when using, unfavorable both hands grip angle might cause rider's discomfort, therefore cause overtired even.

The utility model content

Technical problem to be solved in the utility model is: a kind of bicycle handle angular adjustment structure is provided, makes things convenient for the user to adjust both hands and grip angle and fixed angle really.

For solving the problems of the technologies described above, the utility model adopts following technical scheme: a kind of bicycle handle angular adjustment structure, it comprises that an assembling section, two grip section, two disk covers and a bolt, wherein, described assembling section is connected with the bicycle assembling, its both ends respectively are provided with a pair of folder ear, and each folder ear is provided with perforation; Described two grip the two ends that section is located at the assembling section respectively, and each grips section and is provided with the lug that stretches between the folder ear at the corresponding end that itself and assembling section engage respectively, and each lug is provided with perforation; The center of described each disk cover is provided with for the hollow shaft that penetrates the perforation of folder ear and lug, and is provided with the ingear shaggy tooth on the binding face between each disk cover and each the folder ear; And described bolt locks and connects two disk covers.Mainly utilize under the engagement of shaggy tooth, increase gripping the fixed angle effect of section.

The utlity model has following beneficial effect:

1, under the bolt locking state that places between folder ear and the lug, reaches urgent effect between order folder ear and the lug, and then constitute locking and connecting of two assembling sections and both sides gripping section, and the angle that both sides grip between the section is fixed; Otherwise, placing after bolt between folder ear and the lug unclasps, can remove the engagement of shaggy tooth, and the angle between the holding end bar on change both sides, that is the gripping angle of adjustment both hands, and after bolt locking, utilize the engagement of shaggy tooth, the gripping angle of adjusting is fixing really, grip section by bolted connection, and can utilize simply the action that unclasps/screw bolt, be adjusted to the angle that meets the gripping of rider's both hands most gripping section, so can significantly promote rider's traveling comfort, and promote rider's handling to bicycle.

2, the gripping section on assembling section and both sides is disassembled, therefore can use for the gripping section of changing different size voluntarily.

Below in conjunction with accompanying drawing the utility model is described in further detail.

The specific embodiment

As shown in Figures 2 and 3, be preferred implementation of the utility model, it provides a kind of bicycle handle angular adjustment structure, comprising: assembling section 31, two grip section 32, two disk covers 33 and bolts 34.

Wherein: described assembling section 31 supplies and bicycle assembling bonded assembly structure for integral grip, two end respectively is provided with a pair of folder ear 313, each folder ear 313 is provided with perforation 314, and is provided with for the recess 315 of inserting disk cover 33 in perforation 314 lateral surfaces of this folder ear 313.

Described two grip the two ends that section 32 is located at assembling section 31 respectively, be the structure that grips for the rider, these two grip section 32 and are provided with the lug 321 that stretches between the folder ear 313 at the corresponding end that itself and assembling section 31 engage respectively, and each lug 321 is provided with bores a hole 322.

The center of described each disk cover 33 is provided with for the hollow shaft 331 that penetrates the perforation 314,322 on folder ear 313 and the lug 321.

Described bolt 34 is used for two disk covers 33 are locked mutually.

Also being provided with on the binding face between each disk cover 33 and each recess 315 can intermeshing shaggy tooth 50; The hollow shaft 331 of disk cover 33 can utilize inside and outside tooth fit system as shown in Figure 4 to place mutually with the perforation 322 on the lug 321, perhaps places mutually with non-just round external form contour design, to rotate mutually between restriction disk cover 33 and the gripping section 32.
