The utility model provides a guide mechanism of a bicycle, which comprises a front fork vertical tube, a handlebar vertical tube, a frame front tube, a ball rack, an upper end bowl, a lower end bowl and a ball rack cover, wherein the guide mechanism of the bicycle further comprises a connector and a fastener, the connector is hollow, grooves are formed at the upper and the lower ends of the connector respectively and pass through the wall of the connector, and the lower end part of the connector takes the shape of an inverted cone; the inner wall surface of the ball rack cover takes the shape of an inverted cone, the upper end of the front fork vertical tube is inserted into the lower end of the connector, the fastener is engaged with the lower end of the connector, and the connector is fixedly connected with the front fork vertical tube; the lower end part of the connector is butted against the inner wall surface of the ball rack cover; and the upper part of the connector is fixedly connected with the handlebar vertical tube through the fastener. The front fork vertical tube and the handlebar vertical tube are fixedly connected together through the connector and the fastener, so as to provide convenience for assembly and disassembly. The utility model overcomes the problems in the prior art that the front fork vertical tube and the ball rack cover are in a threaded connection; when the handlebar vertical tube is detachably connected with the front fork vertical tube through the thread of the ball rack cover, the thread is liable to damages; and the font fork has a short service life, and can effectively prolong the service life of the front fork.
Description
Technical field
The utility model relates to a kind of device of bicycle, especially a kind of guiding mechanism of bicycle.
Background technology
Present prior art, a kind of guiding mechanism of bicycle comprises vertical tube of front fork, stem, the preceding pipe of vehicle frame, pearl frame, upper end bowl, lower end bowl and pearl frame lid; The upper and lower end bowl lays respectively at the top and bottom of the preceding pipe of vehicle frame, be separately positioned on the pearl frame in the upper and lower end bowl, pearl frame in the bowl of lower end cooperates with the guide holder on the vertical tube of front fork, and the outside thread on pearl frame lid and the vertical tube of front fork screws, and the pearl frame in the bowl of upper end cooperates with pearl frame lid; The screw thread fit of one fastening cover and vertical tube of front fork upper end removably connects stem and vertical tube of front fork.Existing problems are: in the process of long-term use, the pearl frame covers the thread failure on screw thread and the vertical tube of front fork, causes front fork to be scrapped, and service life is short.
Summary of the invention
The purpose of this utility model is: a kind of guiding mechanism of bicycle is provided, and it not only dismantles, easy for installation, but also can prolong the service life of front fork.
The utility model is achieved in that a kind of guiding mechanism of bicycle, comprises vertical tube of front fork, stem, the preceding pipe of vehicle frame, pearl frame, upper end bowl, lower end bowl and pearl frame lid; The upper and lower end bowl lays respectively at the top and bottom of the preceding pipe of vehicle frame, is respectively arranged with the pearl frame in the upper and lower end bowl, and the pearl frame in the bowl of lower end cooperates with the guide holder on the vertical tube of front fork, and the pearl frame in the bowl of upper end cooperates with pearl frame lid; Its special character is: also comprise a connection piece and tightening buckle;
Described attaching parts hollow, upper/lower terminal have the groove that connects wall thickness respectively, and the bottom of attaching parts is the rounding taper type;
The internal face of described pearl frame lid is the rounding taper type, and insert in the lower end of attaching parts the upper end of vertical tube of front fork, and a tightening buckle cooperates with the attaching parts lower end, and attaching parts is captiveed joint with vertical tube of front fork; The internal face of the bottom of attaching parts and pearl frame lid against;
The top and the stem of attaching parts are fixed together with tightening buckle.
The guiding mechanism of described bicycle, its special character is: described stem is identical with the vertical tube of front fork diameter.
The guiding mechanism of described bicycle, its special character is: the upper end of described attaching parts cooperates with stem, and the attaching parts lower end cooperates with vertical tube of front fork; Stem slidably cooperates with vertical tube of front fork.
The guiding mechanism of the utility model bicycle, owing to adopt such structure, attaching parts is fixed together by tightening buckle and vertical tube of front fork and stem, installation, convenient disassembly; Overcome in the prior art, vertical tube of front fork and pearl frame lid is threaded, and when the lid silk removably connected stem and vertical tube of front fork, screw thread was fragile, the shortcoming that front fork is lacked service life; Can effectively prolong the service life of front fork.
