Abstract
The utility model relates to a bicycle handlebar which comprises a connector on the central section, a vertical jacket on the rear end and a horizontal jacket on the front end, wherein the vertical jacket comprises two annular clamp parts integrally formed on a connector, and a vertical shaft hole is formed between the two. Each clamp part is provided with a wing plate with a connection hole, and two wing plates are arranged oppositely. The horizontal jacket comprises a first buckling part having a bayonet with a semicircular cross section and a second buckling part having a bayonet with a semicircular cross section, and the first buckling part and the second buckling part are integrally formed on a connector and buckled up to form a horizontal shaft hole. A lateral boss is arranged on the end wall, where the first buckling part contacts the second buckling part, and a lateral groove cooperating with the boss is arranged on the end wall of the second buckling part. The first buckling part is provided with a screwed hole, and the second buckling part is provided with a through hole facing the screwed hole. The bicycle handlebar further comprises a fastening bolt passing from the external to the internal, and the front end of the fastening bolt is tightened in the screwed hole.
Description
Technical field
The utility model belongs to bicycle assembly parts technical field, relates in particular to a kind of cycle arm.
Background technology
In modern society, bicycle becomes the preferred traffic instrument of people's short range go off daily, and along with the popularization of the theories such as energy-saving and emission-reduction, healthy trip, bicycle is subject to people's favor day by day.The fork arm at the handlebar of bicycle and front fork top generally adopts and is connected vertical.Vertical rear end have vertical axis hole for the axis hole that connects front fork fork arm, front end and there is level for connecting handlebar.In prior art, be that horizontal shaft hole part generally comprises pedestal and is fastened on the pressing plate on pedestal the vertical upper part for fixing handlebar, pressing plate adopts bolt and pedestal to be connected and fixed, and handlebar is clamped between the two.And pressing plate is generally the plate body of inwall with radian, the contact portion after fastening and between pedestal is almost plane.There is certain defect in said structure: the working accuracy that is limited to pedestal and pressing plate mating surfaces, after actual fastening, both contact surfaces are not complete plane, but the plane being formed by multiple contact points, both fastenings are just so infirm like this, after vibrations rub for a long time, the position of contact is easy to occur wearing and tearing and causes handlebar loosening.
Utility model content
The utility model for solve the technical matters existing in known technology provide a kind of to handlebar provide stablize affixed, still can guarantee reliable fixing cycle arm while using for a long time.
The utility model for the technical scheme that solves the technical matters that exists in known technology and take is: cycle arm comprise be positioned at middle part connector, be positioned at the vertical chuck of rear end and be positioned at the horizontal chuck of front end; Described vertical chuck comprises two semiorbicular clamping sections that are shaped in described connector, forms vertical axis hole between the two, is equipped with the wing plate with connecting bore on each clamping section, and two wing plates are oppositely arranged; Described horizontal chuck comprises the first buckling parts of the bayonet socket with semi-circular cross-section that is shaped in described connector and the second buckling parts of the bayonet socket with semi-circular cross-section that is fastened and connected with it, forms horizontal shaft hole after fastening between the two; On the end wall contacting with the second buckling parts at described the first buckling parts, be provided with horizontal projection, on the end wall of described the second buckling parts, be provided with the horizontal groove coordinating with described projection; On described the first buckling parts, be provided with tapped bore, on described the second buckling parts, be provided with the open-work aligning with tapped bore, also comprise that ecto-entad passes described open-work, front end is tightened in the binding bolt in described tapped bore.
Advantage of the present utility model and good effect are: cycle arm of the present utility model is by being designed to two buckling partss of horizontal axle sleeve projection and the form of groove fit, have solved in the situation that available technology adopting plane coordinates fixing not firm, the problem of easily wearing and tearing and getting loose while using for a long time brought due to a contact.
Preferably: the direction of described projection and groove is all parallel to the line of centers of described horizontal shaft hole.
Accompanying drawing explanation
Fig. 1 is main TV structure schematic diagram of the present utility model and part sectional view.
In figure: 1, connecting bore; 2, wing plate; 3, vertical axis hole; 4, vertical chuck; 5, connector; 6, the first buckling parts; 7, tapped bore; 8, groove; 9, projection; 10, binding bolt; 11, the second buckling parts; 12, horizontal shaft hole.
The specific embodiment
For further understanding summary of the invention of the present utility model, Characteristic, hereby exemplify following examples and be described in detail as follows:
Refer to Fig. 1, the utility model comprise be positioned at middle part connector 5, be positioned at the vertical chuck 4 of rear end and be positioned at the horizontal chuck of front end, wherein vertically chuck 4 is for carrying out affixedly with bicycle front fork fork arm, horizontal chuck is for carrying out affixed with bicycle handle bar.
Vertically chuck 4 comprises two semiorbicular clamping sections that are shaped in connector 5, is formed for the vertical axis hole 3 of accommodating bicycle front fork fork arm between the two, is equipped with 2, two wing plates 2 of wing plate of connecting bore 1 and is oppositely arranged on each clamping section.By wear the fasteners such as bolt in connecting bore 1, vertical chuck 4 is held tightly on front fork fork arm.
Horizontal chuck comprises the first buckling parts 6 of the bayonet socket with semi-circular cross-section that is shaped in connector 5 and the second buckling parts 11 of the bayonet socket with semi-circular cross-section that is fastened and connected with it, is formed for the horizontal shaft hole 12 of accommodating bicycle handle bar after fastening between the two.
On the end wall contacting with the second buckling parts 11 at the first buckling parts 6, be provided with horizontal projection 9, be provided with and the projection 9 horizontal grooves 8 that coordinate on the end wall of the second buckling parts 11, after fastening, projection 9 falls in groove 8.In this example, the direction of projection 9 and groove 8 is all parallel to the line of centers setting of horizontal shaft hole 12.
On the first buckling parts 6, be provided with tapped bore 7, on the second buckling parts 11, be provided with the open-work aligning with tapped bore 7, also comprise that ecto-entad passes open-work, front end is tightened in the binding bolt 10 in tapped bore 7.
