Segmental arc and cathetus section junction and cathetus section and rear segmental arc junction, described front segmental arc and rear segmental arc are the most curved
Stretching out, the inner chamber of described cathetus section constitutes chain and walks passage.
The wall thickness of the medial wall of the breeches pipe of described transmission side is more than the wall thickness of lateral wall.
Vehicle frame, front fork and bicycle basket are high-strength aluminum alloy material material.
Also include the rim brake being arranged on handlebar, the brake cable of described rim brake via the through hole on handlebar at the pipe of handlebar
Intracavity is arranged.
Compared with prior art, the beneficial effects of the utility model are:
The vehicle frame of public bicycles of the present utility model, the transmission side at vehicle frame Chain stay does and deforms, and widens overstriking transmission
Rear flank lower fork, and offer driving hole at Chain stay, chain penetrates from driving hole, passes.Chain passes from vehicle frame Chain stay and passes
Dynamic, reduce the sleet erosion to chain, and play anti-theft feature.This vehicle frame tailored appearance, and carry out taking out wall process, decrease car
Frame weight, and change original moulding, add the chain anti-theft of public bicycles.Meanwhile, bicycle basket when utilizing welding, strengthen
Its load-carrying properties, and improve anti-theft effect further.
Accompanying drawing explanation
Fig. 1 show the body frame structure for automotive schematic diagram of guarding against theft type public bicycles of the present utility model；
Fig. 2 show handlebar and basket structure schematic diagram.
Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, this utility model is described in further detail.Should be appreciated that this place
The specific embodiment described, only in order to explain this utility model, is not used to limit this utility model.
As shown in Figure 1, 2, guarding against theft type public bicycles of the present utility model includes high-strength aluminum alloy material, such as A6061
The vehicle frame 1 of aluminum alloy material and front fork, described vehicle frame includes sitting pipe 2, with described sit front pipe 3 that sealing of tube is connected, afterwards on
Fork 4 and Chain stay 5, and the handlebar 7 being connected is fixed with described front fork, and the bicycle basket 8 being welded to connect with described handlebar,
Described handlebar is made up of tubing welding.Specifically, it is positioned at described sitting pipe front portion and weld with described seat pipe lower end even
The front pipe connect, Chain stay is positioned at seat pipe rear portion and is welded to connect with sitting pipe lower end, and Seat stay connects Chain stay rear end and sits on pipe
End and two ends are welded to connect with seat pipe and Chain stay respectively, are welded with in the middle of the upper end of two Seat stays of the left and right sides meanwhile
Strengthen bar.
Wherein, described handlebar 7 includes the hand steered pipe of both sides L-shaped, three transverse tubes intercepted with described hand steered sealing of tube, institute
Being welded with bicycle basket on front side of the lower end of the hand steered pipe stated, described bicycle basket 8 is welded by aluminium alloy rod is crisscross, utilizes L-shaped
Hand steered pipe, reduces the position of bicycle basket, while improving load carrying behaviour so that it is more can be easy to place higher article, improves and uses
Convenience, i.e. handlebar, bicycle basket integral structure, changes original bicycle basket structure less than normal simultaneously, and uses sunk type to design, add
Big bicycle basket glove volume, ensures the intensity of integral type bicycle basket by brand-new design.
Preferably, for improving containment, in particular for the receiving effect of the cups such as coffee cup, at described bicycle basket one
The circular ring that at least two is coaxially disposed up and down and vertical spacing is arranged it is fixedly installed at angle.Described circular ring interior
Footpath the most progressively reduces, and so can be suitable for different size of cup.
Further, also including the rim brake 9 being arranged on handlebar, the brake cable 10 of described rim brake is via leading on handlebar
Hole is arranged in the tube chamber of handlebar, and in employing tube chamber, the mode of cabling, reduces the interference before bicycle basket, and can effectively prevent from disliking
Meaning is destroyed, and improves safety.
Preferably, for preventing chain to be etched, the lateral surface of the front end of the breeches pipe of Chain stay 5 transmission side and the inner side of rear end
The driving hole 6 allowing chain to walk it is respectively formed with on face.Specifically, the breeches pipe of described transmission side include front segmental arc, in
Straightway and rear segmental arc, described driving hole 6 be respectively formed at front segmental arc and cathetus section junction and cathetus section and after
Segmental arc junction, described front segmental arc and rear segmental arc is the most curved stretches out.Meanwhile, sky is walked for proof strength and chain
Between, the wall thickness of described transmission side breeches pipe wants big more than the breeches pipe wall thickness of opposite side and caliber, meanwhile, transmits the inner side of side breeches pipe
Wall is bigger than lateral wall thickness, so that the support strength of entirety is effectively ensured, ensures the screening effect of lateral wall simultaneously, it is preferable that
For saving material, described rear segmental arc cross section is less than cathetus section, segmental arc cross-sectional sizes after reduction, effectively saves material, simultaneously
It is easy to the installation etc. of trailing wheel, reduces volume and take.
This utility model does at the transmission side of Chain stay and deforms, and widens overstriking transmission side Chain stay, and offers at Chain stay
Driving hole, chain penetrates from driving hole, passes.Chain through transmission, reduces the sleet erosion to chain from vehicle frame Chain stay,
And play anti-theft feature.This vehicle frame tailored appearance, and carry out taking out wall process, decrease vehicle frame weight, and change original moulding,
Add the chain anti-theft of public bicycles.
The above is only preferred implementation of the present utility model, it is noted that general for the art
For logical technical staff, on the premise of without departing from this utility model principle, it is also possible to make some improvements and modifications, these change
Enter and retouch and also should be regarded as protection domain of the present utility model.
