Description
Technical field
The present invention relates to the brake device of bicycle, especially a kind of brake lever and handle are set to the bicycle rotary brake handle device of one.
Background technology
Chinese patent ZL94237277.8 discloses a kind of " the rotary bicycle brake brake gear of handle ", it is characterized in that left rotation and right rotation device housing is fastened on the bicycle handle bar two ends respectively, free handle is enclosed within on the handlebar, the runner affixed with free handle is embedded in the cavity of spinner housing, the through hole that steel wire passes on the cavity is wound on the runner, circumferential groove that embeds for steel wire and the axial groove that snaps in for steel wire head are arranged on the runner, though this device has had braking soon, willing characteristics, but its complex structure, the spinner housing takes up room greatly, it is attractive in appearance that profile is owed, the parts manufacturing process is also loaded down with trivial details relatively, especially concerning Folding Bicycle, the described structure of this patent can not be used, thereby needs further to improve on this basis.
Summary of the invention
The purpose of this invention is to provide a kind of bicycle rotary brake handle device that is applicable to ordinary bicycle and Folding Bicycle.
Technical scheme of the present invention is achieved in that
A kind of bicycle rotary brake handle device is provided, its structure is: have a metal sleeve to insert in the metal tube of handle-bar body, metal sleeve is provided with a positioning groove, with dowel bolt insert the counterbore of brake lever housing and pass the handle-bar body metal tube the knock hole that is used for fixing dowel bolt and metal sleeve is limited, make that the metal sleeve that is circumscribed with the handle handguard can be along the groove of positioning groove to doing spinning movement; One brake cable fixed orifice is arranged on the metal sleeve, one brake lever housing fairlead is arranged on the brake lever housing, brake cable fixed orifice center and brake lever housing fairlead are centered close on the same cross section perpendicular to the metal sleeve axis, brake cable is wrapped in the metal sleeve surface, one end of brake cable connects and is fixed in the brake cable fixed orifice of metal sleeve, and the other end of brake cable passes brake lever housing fairlead and connects with bicycle brake device.The groove that the brake cable fixed orifice also can be set to a kind of and positioning groove is to the slotted eye of vertical and the half opening that is communicated with.
After above-mentioned the setting, its brake process is: rotation handle handguard drive metal sleeve along the groove of positioning groove to doing spinning movement, and then the brake cable that drives the metal sleeve surface does to twine and rotates, brake cable drives the bicycle brake device action; Otherwise then bicycle brake device resets.
Aforesaid bicycle rotary brake handle device, described positioning groove circumferentially is provided with at an angle along the metal tube of handle-bar body, and its angular dimension is controlled at less than 180 degree and is advisable; And make the arc length of positioning groove match with brake cable positive braking spacing.
Aforesaid bicycle rotary brake handle device has a brake cable fixture in the brake cable fixed orifice of described metal sleeve, in order to a fixing end of brake cable, described brake cable fixture is a spherical body or a columnar object.
Of the present invention simple in structure to have a braking fast, has attractive appearance, and advantage of low manufacturing cost is applicable to the control of various bicycle brake devices.
Description of drawings
Fig. 1 is the scheme drawing of cut-away section in the structure of the present invention.
Fig. 2 is the structural representation that Fig. 1 crosses brake cable fixed orifice center and brake lever housing fairlead central cross-section.
Fig. 3 is the scheme drawing that a kind of brake cable fixed orifice among Fig. 1 is the slotted eye of half opening.
The specific embodiment
A kind of bicycle rotary brake handle device is provided, there is a metal sleeve 4 to insert in the metal tube 8 of handle-bar body, metal sleeve 4 is provided with a positioning groove 7, with dowel bolt 1 insert the counterbore of brake lever housing 2 and pass the handle-bar body metal tube 8 the knock hole that is used for fixing dowel bolt 1 and metal sleeve 8 is limited, make that the metal sleeve 4 that is circumscribed with handle handguard 5 can be along the groove of positioning groove 7 to doing spinning movement; One brake cable fixed orifice 6 is arranged on the metal sleeve 8, one brake lever housing fairlead 2 is arranged on the brake lever housing, on the cross section that is centered close to same axis perpendicular to metal sleeve 4 of the center of brake cable fixed orifice 6 and brake lever housing fairlead 3, brake cable 9 is wrapped in the surface of metal sleeve 4, one end of brake cable 9 connects and is fixed in the brake cable fixed orifice 6 of metal sleeve 4, and the other end of brake cable 9 passes brake lever housing fairlead 2 and connects with bicycle brake device.Described brake cable fixed orifice 6 also can be set to the slotted eye 11 of a kind of groove of and positioning groove 7 to vertical half opening, and the half opening end of this slotted eye 11 is communicated with positioning groove 7, can conveniently insert cable wire and fixture thereof.
Positioning groove 7 is along the circumferentially setting at an angle of the metal tube 8 of handle-bar body as mentioned above, and its angular dimension is controlled at less than 180 degree and is advisable; And make the outer arc length of positioning groove 7 match with brake cable positive braking spacing.
Aforesaid bicycle rotary brake handle device has a brake cable fixture 10 in the brake cable fixed orifice 6 of described metal sleeve 4, in order to a fixing end of brake cable 9, described brake cable fixture 10 is a spherical body or a columnar object.
This set can be applicable to all bicycles, especially Folding Bicycle, have the institute take up space little, the characteristics of structure dexterity.
With this structure is the scope that other numerous embodiments of feature all falls into the present invention's protection.
