Abstract
The utility model relates to a connection mechanism for a handle bar and front fork of a bicycle. The front pipe of a bicycle frame is inserted into a vertical pipe of a front fork; an upper bearing and a lower bearing are used for limiting looseness; a rotating base is used as a platform of a handle bar and the lower part of the platform is provided with a short pipe which is inserted into the vertical pipe of a front fork for coupling; a pressing device presses the rotating base on the upper bearing through an anti-rotation gasket; the force of the platform of a handle bar can be directly transferred to the front pipe of a bicycle frame; the coupling section between the handle bar and the front fork can be obviously shortened; besides, the bonding strength and the reliability of the coupling section can be ensured; the mechanism is suitable for the use of a folding bicycle.
Description
The utility model relates to the bindiny mechanism of bicycle handle bar and vertical tube of front fork and the preceding pipe of vehicle frame.
The traditional bicycle handle bar and the standpipe of front fork stretch at the two ends up and down of pipe before the vehicle frame, and stem inserts in the vertical tube of front fork, make front fork and handlebar coupling with an overbolt.The handlebar of coupling, front fork between pipe and front fork bearing be housed respectively before the vehicle frame, so that can be managed and be rotated not radial and axial becoming flexible relative to vehicle frame before.The length that traditional this bindiny mechanism must guarantee vertical tube of front fork is greater than more than three, four times of its diameter, otherwise is not enough to guarantee the coupling stiffness and the intensity of its coupling, therefore causes whole bindiny mechanism long higher in other words.The preceding pipe of vehicle frame is long partially to have no adverse effect to standard bicycle, but for folding bicycle or horizontal bicycle, the preceding pipe of Chang vehicle frame takes up space greatly partially, for folding or the design of horizontal bicycle brings many difficulties.
The bindiny mechanism that the utility model is intended to provide a kind of short weak point and can guarantees the bicycle handle bar and the front fork of Joint strenght and reliability is to reduce the occupied space of this mechanism, for design collapsible, horizontal bicycle brings convenience.
The bindiny mechanism of handlebar described in the utility model and front fork, pipe is equipped with bearing frame up and down respectively before the vehicle frame, pipe and standpipe were equipped with respectively up and down and are equipped with ball formation metal (upper in the middle of the bearing frame of pipe matches before bearing frame and the vehicle frame before vertical tube of front fork ran through, the vertical tube of front fork top has a steering base as handlebar to link to each other with vertical tube of front fork, being lined with an anti-rotation pad between the bearing frame of steering base bottom surface and vertical tube of front fork upper end (has a boss to snap in the longitudinal slot of standpipe wall on this pad inner diameter wall, be prior art), steering base is compressed the anti-rotation pad and be pressed on the head bearing frame of vertical tube of front fork by pinch device.
Described bindiny mechanism, its steering base is exactly a handlebar platform, adorn two horizontal handles simply, just be equivalent to conventional handlebar, if the height that folding handle vertical tube also can be adjusted handle is housed, if steering base is made gear then is suitable for horizontal bicycle, the bicyclist is being turned to than controlling handlebar with the type of drive of gear or chain at a distance.Because steering base (handlebar) not only links to each other with vertical tube of front fork, also directly be pressed on the bearing frame by the anti-rotation pad, be that the power that can produce moment of flexure on the handlebar can be directly delivered to without vertical tube of front fork before the vehicle frame on the pipe, therefore the mutual coupling section of handlebar and vertical tube of front fork needn't be so longly required as traditional approach, adopts very short seat tube to be enough to guarantee its Joint strenght and reliability.The short weak point of described bindiny mechanism, it is little to take up space, and selects for use for design collapsible, horizontal bicycle and brings a lot of convenience.
Fig. 1 is a kind of assembling relationship figure of described mechanism.
Fig. 2 is a kind of assembling relationship figure of described mechanism.
Implement one: as Fig. 1
Vertical tube of front fork 9 runs through pipe 8 before the vehicle frame from bottom to top, standpipe 9 about bearing frame 3 and the bearing frame 4 corresponding formation bearings on the preceding pipe 8.Steering base 1 bottom has short tube 5 to insert flush fit in the vertical tube of front fork 9, be lined with anti-rotation pad 2 between the bearing frame 3 on steering base 1 bottom surface and standpipe 9 tops, be fixed with nut 7 in the vertical tube of front fork 9, steering base 1 center is porose, pinch device is that lock bolt 6 passes in the steering base 1 screw-in nut 7, and steering base 1 is pressed on the head bearing frame 3 by anti-rotation pad 2.Because the short tube 5 under the steering base is a flush fit with standpipe 9, during maintenance that both separation are difficult, so the hole at steering base 1 center is a tapped bore and greater than the hole of nut 7, when using the bottom diameter greater than the bolt 6 in nut 7 holes, the nut 7 that its bottom props up in the standpipe continues to screw in, and steering base 1 can be pulled out in standpipe 9.
Implement two: as Fig. 2
Pinch device is that nut 10 screws with the top of vertical tube of front fork 9 on steering base 1.The bottom surface of steering base 1 is compressed anti-rotation pad 2, and be pressed in the tolerance clearance of adjust a bearing on the bearing frame 3.All the other are identical with embodiment one.
Claims (4)
1, the bindiny mechanism of bicycle handle bar and front fork, pipe (8) is equipped with bearing frame (4) up and down respectively before the vehicle frame, vertical tube of front fork (9) runs through preceding pipe (8), be equipped with ball in the middle of the bearing frame (4) that standpipe (9) is equipped with bearing frame (3) and preceding pipe (8) up and down respectively matches and constitute metal (upper, it is characterized in that, vertical tube of front fork (9) top has a steering base as handlebar (1) to link to each other with vertical tube of front fork (9), steering base (1) is compressed anti-rotation pad (2) and is pressed on the bearing frame (3) of vertical tube of front fork (9) epimere by pinch device.
2, by the described bindiny mechanism of claim 1, it is characterized in that, steering base (1) bottom has a short tube (5) to insert flush fit in the vertical tube of front fork (9), steering base (1) center is porose, fix a nut (7) in the standpipe (9), pinch device is that the centre hole that lock bolt (6) passes steering base (1) links to each other with nut (7).
3,, it is characterized in that the centre hole of steering base (1) is a tapped bore and greater than the tapped bore of nut (7) by claim 1 or 2 described bindiny mechanisms.
4, by the described bindiny mechanism of claim 1, it is characterized in that nut is arranged (10) on steering base (1), screw with the top of vertical tube of front fork (9) and to be pinch device (6).
