Description
Technical field
Before the utility model is related to bicycle designs manufacturing field, more particularly to a kind of bicycle of high strength easy dismounting
Fork.
Background technology
Existing bicycle front fork is mostly the form being welded in the prong of both sides on vertical tube, and traditional vertical tube uses more
Hollow aluminium pipe structure is inherently relatively low in intensity to mitigate weight；And since welding procedure is there are phenomena such as stomata, dry joint,
Therefore the intensity of weld is lower.To solve the above-mentioned problems, the Chinese patent of Application No. 201420832520.4 discloses
A kind of bicycle of front fork and the application front fork, its by the way that front fork is divided into left fork leg and right fork leg along vertical tube, left fork leg and
Right fork leg is an integral molding structure, and left fork leg connects to form front fork with right fork leg by attachment device, it possesses bicycle
The original function of front fork and avoid traditional front fork structure and phenomena such as overlap, dry joint occur.The riser portions are by two songs
Face pieces together a complete cylindricality, its mosaic is also easy to produce gap, and the intensity of vertical tube in itself decreases, while fixed knot
Structure is compound, and dismounting is more troublesome.
Utility model content
In order to solve the above-mentioned technical problem, there is provided a kind of intensity height, good airproof performance, the split type front fork being readily disassembled, this
Utility model provides following technical scheme：
A kind of bicycle front fork of high strength easy dismounting, including left front fork leg, right fork blade, upper capping and lower capping；Institute
State left front fork leg includes integrally formed right breeches pipe and right prong including integrally formed left breeches pipe and left prong, right fork blade；
The left breeches pipe and right breeches pipe are hollow semicircle column type and include arcwall and center wall, in the left breeches pipe
Fluted and raised, the left side of being also staggered is staggeredly equipped with the center wall of groove and raised, described right breeches pipe on heart wall
Breeches pipe and right breeches pipe pass through groove and the raised center for cooperatively forming a complete cylinder, the left breeches pipe and right breeches pipe
Wall correspondence position also offers axial location hole respectively, and the location hole passes through groove and protrusion；The lower capping includes lid
Body and two connecting shafts integrally formed with lid upper surface, the connecting shaft is through location hole and stretches out left breeches pipe and right fork
Pipe；The upper capping is close to arcwall to be connect and lower surface offers groove body for housing connecting shaft upper end.
The left breeches pipe and right breeches pipe of the utility model be relative closure semi-cylindrical pipe, wherein center wall there are a side
Face can be used for strengthening the intensity of front fork, is on the other hand not susceptible to relatively by groove and raised setting left and right breeches pipe
Slide；Meanwhile left and right breeches pipe is also further fixed by connecting shaft so as to improve the stability of structure, and by one end of connecting shaft
The dismounting that left and right breeches pipe is then the later stage for convenience is stretched out, the part for stretching out breeches pipe is used to make lid depart from fork as impetus
Foot, it is easy to operate；On the one hand upper capping is used to provide the space for accommodating connecting shaft extension, on the other hand as front fork and hand
Connector.
Further, the connecting shaft stretches out the length of left breeches pipe and right breeches pipe part less than the height of groove body, the company of preventing
Spindle upper end is under pressure and slide downward.
Further, the lid upper surface fits with left fork leg and right fork leg junction, and lid thickness is from center
It is gradually reduced to edge so that relative smooth between lower capping and prong, advantageously reduces the windage of junction.
Further, the connecting shaft stretches out left breeches pipe and the part of right breeches pipe is bent downward, and preferably prevents lower capping
Abjection.
The beneficial effects of the utility model are：The intensity of front fork is considerably increased by the setting of two layers of center wall, is led to
Cross the setting of male-female engagement and connecting shaft so that left and right breeches pipe that opposite slip, structural stability will not occur is good, and be easy to tear open
Unload.
