Description
Technical field
The invention belongs between the pipe fitting and be connected and fixed, particularly a kind of bundle substructure of clamp fitting two folding pipe fittings is particularly useful for being connected and fixed between folding a plurality of pipe fittings in the folding bicycle.
Background technology
In the prior art, folding bicycle is realized folding effect by fold mechanism is installed on the pipe fitting, usually this fold mechanism is made up of hinged left folding seat of a side and right folding seat, this left folding seat and right folding seat are welded in two folding pipe fittings respectively, and this left folding seat and right folding seat opposite side are realized two folding pipe fitting fastenings by a quick detach assembly.
For the folding bicycle front and back wheel when folding, need to realize by the fold mechanism at pipe middle part is installed down, for folding bicycle traffic safety, reliable, this front fork vertical bar with should in also be provided with on the bonded assembly above between the pipe and manage.For the folding bicycle of such structure, realize between the folding bicycle front and back wheel folding, must pipe down and on manage respectively that correspondence is provided with two fold mechanisms.Like this will same folding direction (front and back wheel doubling) must be respectively pipe down and on pipe two fold mechanisms are installed respectively owing to design, make and error that operation produces, it is quite difficult wanting to reach two free and relaxed folding effects of fold mechanism.
Summary of the invention
In order to remedy above deficiency, the invention provides a kind of bundle substructure, can fold pipe fittings by reliable and stable ground clamp fitting two, reach locking and open very good effect.
Technical scheme of the present invention is to realize: a kind of bundle substructure, be installed on two folding pipe fitting connecting portions, comprise beam tube, can extend into fixed fold pipe and activity folded tube in these beam tube two ends respectively with open slot, the open slot of this beam tube is provided with the clamping mechanism of being convenient to this fixed fold pipe of clamp fitting and activity folded tube, this fixed fold pipe is provided with location notch hole vertically, and this beam tube is limited in the location notch hole on this fixed fold pipe by the set screw that is rotated with and slides.
Further improve as the present invention, also wear a lining between this beam tube and this fixed fold pipe, after this set screw is fixed this beam tube and lining, be defined on this fixed fold pipe and slide in the knock hole with open slot.
Further improve this lining and corresponding respectively protuberance and the assembly opening of being convenient to install that be provided with of this beam tube as the present invention.
Further improve as the present invention, also be provided with gag between this lining and this activity folded tube, this gag one end is provided with the mouth of pipe that dwindles of open slot, be convenient to be installed in this lining, and the other end is provided with the annular groove of ccontaining this activity folded tube mouth of pipe of energy, also can this gag one end be provided with can ccontaining this lining mouth of pipe annular groove, and the other end is provided with the mouth of pipe that dwindles of open slot, is convenient to be installed in this activity folded tube.
Further improve as the present invention, this clamping mechanism by one group of lug being located at these beam tube upper shed groove both sides side by side, pass the set screw of this group lug and be rotated with and form in the setting nut of this set screw.
Further improve as the present invention, this clamping mechanism passes the adjusting bolt of this group lug, the transverse axis that is fixed in this adjusting bolt end and end rotational fixation by one group of lug, activity being located at these beam tube upper shed groove both sides and forms in the spanner of this transverse axis, the end outer rim of this spanner is the eccentric cam shape, and this adjusting bolt other end is rotated with setting nut.
Further improve as the present invention, this fixed fold pipe and activity folded tube are respectively forms the two folding pipe fittings of going up pipe in the folding bicycle.
Useful technique effect of the present invention is: the beam tube two ends in the described bundle substructure are placed in the fixed fold pipe and the activity folded tube mouth of pipe respectively, make that by the location notch hole on set screw and this fixed fold pipe this beam tube can be along this fixed fold tubular axis to slip simultaneously, design is when opening this beam tube upper clamping mechanism like this, this beam tube can freely be enclosed within this fixed fold pipe and the activity folded tube butt joint mouth of pipe, because the corresponding mouth of pipe of this beam tube pivot bush unit, so even two butt joint mouth of pipe shaft centre lines are not quite identical, also can be easy to be enclosed within the activity folded tube mouth of pipe, reach clamp fitting two folding pipe fittings with manual operation.
This lining helps between this beam tube and the fixed fold pipe fixing, and the design of this gag also helps fixing between this beam tube, lining and the activity folded tube.
For managing this bundle clamp mechanism of installing on the folding bicycle, because that the fold mechanism that front and rear wheel is installed by this time pipe is realized is folding, this bundle substructure was installed and should go up pipe, also be easy to realization and fold, reach folding convenient, stable effect by bike.
