Abstract

The invention discloses a taper sleeve type locking structure folding handlebar, which comprises a taper head, a taper sleeve, a folding pedestal, a locking bolt, a positioning pin and an oblique tongue. The handlebar is characterized in that: the taper head is integrally connected with an inner extending pipe, the folding pedestal is tightly assembled on the inner extending pipe, two lugs on the folding pedestal are provided with two oblong holes, the lug protrusion at the bottom of the taper sleeve is provided with a pin hole, the pin hole is aligned with the two oblong holes, and a pin shaft passes through the pin hole so that a folding chain which can be pulled up and down and turn over is formed between the taper sleeve and the folding pedestal; and the taper sleeve is matched with the taper head, and the oblique tongue tightens the taper sleeve and the taper head by rotating a knob. The stress strength of the taper sleeve type locking structure folding handlebar is superior to that of a common folding handlebar, the taper sleeve type locking structure folding handlebar has smaller and more attractive appearance, and both the strength and the grade of the folding handlebar are promoted.

Description

Tapered sleeve type locking mechanism folds barre

Technical field:

The present invention relates to a kind of folding barre, particularly a kind of tapered sleeve type locking mechanism folds barre.

Technical background:

The often bigger than normal and barre of the folders of folding barre in the market is combined together, just as a bone of not putting on flesh closes knot, seem coordination not attractive in appearance, and determine a locking face by the folding pivot pin and the quick detach of folded chain, often intensity is very limited, does not reach relevant detection requirement.

Summary of the invention:

Purpose of the present invention, be that a kind of brand-new locking mechanism will be provided, a kind of tapered cover is socketed on the tapered head, be advanced in the lockhole of tapered head with the top of lock bolt then an oblique tongue, and with tapered cover and tapered the folding barre of the tapered sleeve type locking mechanism that tightens up, the object of the present invention is achieved like this: tapered sleeve type locking mechanism folds barre, comprise a tapered head, one tapered cover, one folding pedestal, one lock bolt, one locating stud and an oblique tongue, it is characterized in that: tapered head is connected with the inside extending tube one, joining at tapered head and inside extending tube studs with a lining ring, folding pedestal close-fitting inside extending tube is on one section that is connected with tapered head, have auricle perpendicular on two on the folding pedestal, two auricles all have slotted hole, tapered cover and tapered head match, top socket one barre of tapered cover, one side of bottom, one connects the ear of a band pin-and-hole and dashes forward, in the slotted hole of folding pedestal two auricles and the ear of tapered cover prominent in the pin-and-hole, be installed with one end thread hole bearing pin, then at an end of the tapped hole screw of screwing on, make between tapered cover and the folding pedestal and to form one and can spur up and down, the folded chain that can overturn also is equipped with lock bolt and locating stud tapered putting again.On lock bolt and locating stud, cooperate an oblique tongue, have a knob, twist knob and can make the lock bolt rotation and the oblique tongue of push-and-pull, can make and lock between tapered cover and the tapered head or unclamp at an end of lock bolt.

The invention has the beneficial effects as follows, utilize tapered cover to cooperate tapered head, when tapered cover and tapered head are tightened up, between barre and the inside extending tube to be subjected to force intensity to be better than common folding barre many, and outward appearance is also smaller and more exquisite and attractive in appearance, be not only firm but also attractive in appearance, the intensity and the class of folding barre have been done two liftings.

Description of drawings:

Fig. 1 is a structural representation of the present invention

Fig. 2 is oblique tongue post-tensioning figure of the present invention

Fig. 3 is folding figure of the present invention

Among the figure: 1---tapered head, 2---tapered cover, 3---folding pedestal, 4---lock bolt, 5---locating stud, 6---oblique tongue;

Embodiment:

With reference to Fig. 1, described tapered 1, also comprise the inside extending tube 11 that is connected with described tapered 1 one, one lockhole 12 is arranged on the one side on described tapered 1 top, in the jointing place of described tapered 1 and described inside extending tube 11, stud with a lining ring 13, one hanging bolts 14 and pass described lining ring 13 and screw a bevelled tenon 15 with described inside extending tube 11, by tightening described hanging bolt 14, swelling in the bicycle front fork pipe with described inside extending tube 11 and described bevelled tenon 15;

Described folding pedestal 3 is the described inside extending tubes 11 of close-fitting with described tapered 1 linkage section on, have auricle perpendicular on two on the described folding pedestal 3, all have slotted hole 31 on two auricles;

Described tapered cover 2, be with described tapered 1 match, top close-fitting socket one barre 23 of described tapered cover 2, it is prominent that one side one of described tapered cover 2 bottoms connects an ear, on described ear is prominent a pin-and-hole 21 arranged, and described pin-and-hole 21 is aimed at described two slotted holes 31 of described folding pedestal 3, penetrate the bearing pin 22 in one end thread hole, the screw of screwing on again makes to form one between described tapered cover 2 and the described folding pedestal 3 and can spur up and down, again the folded chain that can overturn;

Described lock bolt 4 and described locating stud 5 are installed in the middle part of described tapered cover 2, on described lock bolt 4 and described locating stud 5, be combined with described oblique tongue 6, end at described lock bolt 4, be furnished with a knob 41, twist described knob 41, make described lock bolt 4 rotate and will push away before the described oblique tongue 6, the bottom of described oblique tongue 6 is stretched in described tapered the 1 described lockhole 12, described tapered cover 2 is tightened up with described tapered 1.

As unclamping the folding barre of tapered sleeve type locking mechanism, only need oppositely twist described knob 41, pull out described tapered 1 lockhole 12 after making described lock bolt 4 bottoms of counter-rotating with described oblique tongue 6, the described tapered cover 2 that draws then and overturn just can be with described barre 23 folding (referring to Fig. 2, Fig. 3).
