Abstract
The handlebar has one U-shaped unit fixed to the top of the vertical pipe, right and left cross pipes hinged to the U-shaped unit, and locating nuts and washers on the cross pipes. Or, the handlebar has two U-shaped units fixed to the tops of the right and left cross pipes, vertical pipe hinged to these two U-shaped units simultaneously, and locating nuts and washers on the vertical pipe, and these two U-shaped units are interlinked mutually and may be rotated relatively. The present invention has high connection strength, firm location, no loosening, high reliability, capacity of locating after interlinking, simple structure, convenient operation and low cost.
Description
Affiliated technical field
The present invention relates to the used folding handle bar of a kind of bicycle, Kickboard Scooter or body-building apparatus.
Background technology
The stem of existing folding bicycle generally all adopts the folding mode that connects a hinge-type folder on stem, and this folding mode has many good qualities, but the handlebar transverse tube is not folding, and lateral dimension is bigger, and is very inconvenient.The Kickboard Scooter that also has adopt the detachable or hinge of cannula type bullet nail location connect bullet nail location the folding handle bar transverse tube, but the both has Joint strenght low, is positioned with the gap, can be loosening, insecure defective, and all do not have the failure-free registration device after folding, the phenomenon that gets loose is arranged.
Summary of the invention
Low in order to overcome existing Foldable handlebar Joint strenght, the location is loosening, and does not have the failure-free registration device after folding, and the defective of the phenomenon of getting loose is arranged, the purpose of this invention is to provide a kind of Foldable handlebar, this Foldable handlebar Joint strenght height, firm position does not have the gap, and is not loosening, the reliability height, and the failure-free location arranged after folding, simple in structure, easy to operate, cost is low.
Technical scheme of the present invention is in U-shaped fetching of stem top fixed connection, the handlebar transverse tube of the right and left is connected with the U-shaped fetching by hinge respectively, by the setscrew nut that has been threaded, the end face of setscrew nut is pressed in the location, both sides of U-shaped fetching by pad on the handlebar transverse tube of the right and left.When handlebar need use, rotate the handlebar transverse tube of the right and left, make it to be in horizontality, rotational positioning nut then, make setscrew nut be pressed on the location, both sides of U-shaped fetching by pad, so just can increase hinged intensity greatly, eliminate the gap of location simultaneously again, prevent loosening phenomenon.When handlebar needs folding, the rotational positioning nut, make setscrew nut break away from the both sides of U-shaped fetching, rotate the handlebar transverse tube of the right and left then, make it to realize folding, positioning of rotating nut again near stem, setscrew nut is located by the other both sides that pad is pressed on the U-shaped fetching, and the handlebar transverse tube after just can preventing to fold produces the phenomenon that gets loose.
Another kind of technical scheme of the present invention is in the U-shaped fetching of fixed connection respectively of the handlebar transverse tube top of the right and left, stem is connected with two U-shaped fetchings simultaneously by a hinge, these two mutual intussusceptions of U-shaped fetching also can rotate mutually, by the setscrew nut that has been threaded, the end face of this setscrew nut is pressed in the location, both sides of two U-shaped fetchings simultaneously by pad on stem.When handlebar need use, rotate the handlebar transverse tube of the right and left, make it to be in horizontality, rotational positioning nut then, make setscrew nut be pressed in the location, both sides of two U-shaped fetchings simultaneously by pad, so just can increase hinged intensity greatly, eliminate the gap of location again, prevent loosening phenomenon.When handlebar needs folding, the rotational positioning nut, make setscrew nut break away from the both sides of U-shaped fetching, rotate the handlebar transverse tube of the right and left then, make it to realize folding, positioning of rotating nut again near stem, setscrew nut is located by the other both sides that pad is pressed on two U-shaped fetchings, and the handlebar transverse tube after just can preventing to fold produces the phenomenon that gets loose.
The invention has the beneficial effects as follows to make Foldable handlebar Joint strenght height, firm position does not have the gap, and is loosening, and reliability height, and the failure-free location is arranged after folding is simple in structure, easy to operate, cost is low.

The specific embodiment
Among Fig. 1, welding is passed through at top at stem 1, U-shaped fetching 2 of fixed connection, the handlebar transverse tube 6 of the right and left is connected with U-shaped fetching 2 by hinge 3 respectively, by the setscrew nut 5 that has been threaded, the end face of setscrew nut 5 is pressed in the location, both sides of U-shaped fetching 2 by pad 4 on the handlebar transverse tube 6 of the right and left.When handlebar 6 needs to use, rotate the handlebar transverse tube 6 of the right and left, make it to be in horizontality, the rotational positioning nut 5 then, make setscrew nut 5 be pressed on the location, both sides of U-shaped fetching 2 by pad 4, when handlebar 6 needs folding, rotational positioning nut 5, make setscrew nut 5 break away from the both sides of U-shaped fetching 2, rotate the handlebar transverse tube 6 of the right and left then, make it near stem 1, realize folding, the positioning of rotating nut 5 again, and setscrew nut 5 is located by the other both sides that pad 4 is pressed on the U-shaped fetching, and the handlebar transverse tube 6 after preventing to fold produces and gets loose.
Among Fig. 2, handlebar transverse tube 6 tops at the right and left are passed through welding U-shaped fetching 8 of fixed connection and U-shaped fetching 7 respectively, stem 1 is connected with 7 simultaneously by a hinge 3 and two U-shaped fetchings 8, these two mutual intussusceptions of U-shaped fetching also can rotate mutually, by the setscrew nut 5 that has been threaded, the end face of this setscrew nut is pressed in the location, both sides of two U-shaped fetchings 8 and 7 simultaneously by pad 4 on stem 1.When handlebar need use, rotate the handlebar transverse tube 6 of the right and left, make it to be in horizontality, the rotational positioning nut 5 then, make setscrew nut 5 be pressed in the location, both sides of two U-shaped fetchings 8 and 7 simultaneously by pad 4, when handlebar needs folding, rotational positioning nut 5, make setscrew nut 5 break away from the both sides of U-shaped fetching, rotate the handlebar transverse tube 6 of the right and left then, make it near stem 1, realize folding, the positioning of rotating nut 5 again, and setscrew nut 5 is located by the other both sides that pad 4 is pressed on two U-shaped fetchings, and the handlebar transverse tube 6 after just can preventing to fold produces the phenomenon that gets loose.In this kind embodiment, can be used for being connected directly in the excircle part machining screw of stem 1 with setscrew nut 5, simultaneously with the end reducing of stem 1, at this reducing position processing pan, be used to install hinge 3, but such Joint strenght is poor slightly.Also can fix a connector 9 in the welding of the end of stem 1, excircle part machining screw at this connector 9, be used for being connected with setscrew nut 5, end with connector 9 processes flat position simultaneously, partly process pan in this flat position, be used to install hinge 3, such Joint strenght is better.Obviously, above-mentioned U-shaped fetching 8 and 7 shapes that its U-shaped can also be protruded the position change depression into, and the position of will caving in welds mutually with end cylindrical one side of leaning on of handlebar transverse tube 6, make handlebar transverse tube 6 be positioned at the outside of U-shaped fetching 8 and 7.
Obviously, in the above-described embodiment, the hinge of telling 3 can be screw, rivet, pin etc.
