Description
Technical field
The utility model relates to technical field of bicycles, particularly the folding of a kind of vehicle frame of Folding Bicycle and handlebar.
Background technology
In the folding joint that existing folding bicycle uses, latch fitting can be sealed with two connecting panel automatic fastenings when closing up for some joint, and this joint is simple and efficient to handle, liked by the user.The mechanism that showed of China Patent No. 200820300021.5 for example, this joint makes hook joint spare front end outwards change around eccentric shaft under the hook joint spare fwd inclined-plane guiding closing up will put in place the time, just buckle into the intercalation part of hook joint spare after putting in place automatically, turning handle can lock folding joint then.But the closure volume of this joint is bigger, and protrusion joint side is a bulk of, and outward appearance is indecency.In addition, this joint also need be provided with a safety button in addition and retrain lock handle, prevents that misoperation from open handle and influence the normal use of bicycle.Consider that together this joint design is looser if connect the safety button, operation does not include quick, if add this joint the bigger factors such as eccentric shaft of difficulty of processing is arranged, and its tooling cost is just higher.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of folding joint that latch fitting can the automatic fastening locking has the security insurance function again when simple and compact for structure, simple and efficient to handle, sealed.
In order to solve the problems of the technologies described above, the technical scheme that the utility model adopted is:
Folding joint of the present utility model includes connecting panel first and connecting panel second and the locking bar that is connected by jointed shaft, described connecting panel first is hinged with a hook joint spare in a relative side that is connected with described connecting panel second, this hook joint spare is provided with and is used to catch on the eave tile portion that described connecting panel second is locked platform portion, handwheel is equipped with in the outer end of described locking bar, be provided with limiting section in the described connecting panel first, the middle part of described locking bar is contained in the spacing hole of the through hole of described hook joint spare and described limiting section, the inner of this locking bar is provided with locating part, and this locking bar is equipped with stop collar at described locating part between the described limiting section of described connecting panel first; Between the limiting section of described connecting panel first and the described stop collar spring is housed, the through hole of described hook joint spare and the spacing hole of described limiting section have at least one to be tapped bore.
In the technique scheme, more particularly: described stop collar towards the external diameter of limiting section one end of described connecting panel first greater than described spacing hole diameter.
Folding joint of the present utility model includes connecting panel first and connecting panel second and the locking bar that is connected by jointed shaft, described connecting panel first is hinged with a hook joint spare in a relative side that is connected with described connecting panel second, this hook joint spare is provided with and is used to catch on the eave tile portion that described connecting panel second is locked platform portion, handwheel is equipped with in the outer end of described locking bar, the middle part of this locking bar is contained in the through hole hole of described hook joint spare, and the inner of this locking bar is installed in the spacing hole of described connecting panel first by locating part; Between described hook joint spare and the described connecting panel first retracing spring is housed, the through hole of described hook joint spare and the spacing hole of described limiting section have at least one to be tapped bore.
Owing to adopted technique scheme, the utility model compared with prior art, the beneficial effect that has is:
1, because hook joint spare is direct and connecting panel first pivotally attached, locking bar passes the through hole at hook joint spare middle part and the spacing hole on the connecting panel first limiting section, these two holes have at least one to be tapped bore, like this, by rotation locking bar turnover, just can reach the degree of tightness of adjusting hook joint spare, tighten locking bar after, hook joint spare can not be opened, sealed reliable and safety very.
2, because the hook joint spare that is hinged with the connecting panel first is provided with the eave tile portion that is used to catch on connecting panel second lock platform portion, when hook joint spare one is pressed on the lock platform, eave tile portion is just sealed automatically, operates very simple and efficient.

The specific embodiment
Below in conjunction with the accompanying drawing example, the utility model is described in further detail:
Embodiment 1:
As Fig. 1,2,3, shown in 4, present embodiment 1 includes connecting panel first 4 and connecting panel second 3 and the locking bar 1 that is connected by jointed shaft, connecting panel first 4 is hinged with a hook joint spare in a relative side that is connected with connecting panel second 3, this hook joint spare is provided with the eave tile portion 2.1 that is used to catch on connecting panel second 3 lock platform portions, handwheel 1.1 is equipped with in the outer end 2 of locking bar 1, be provided with limiting section 4.2 in the connecting panel first 4, the middle part of locking bar 1 is contained in the spacing hole 4.1 of the tapped bore of hook joint spare 2 and limiting section 4.2, the inner of this locking bar is provided with the screw rod 1.2 that plays position-limiting action, this locking bar is equipped with T jacket 6 at screw rod 1.2 between the limiting section 4.2 of connecting panel first 4, the T jacket greater than spacing hole's diameter, is equipped with spring 5 between the limiting section 4.2 of connecting panel first 4 and the T jacket 6 towards the external diameter of limiting section one end of connecting panel first 4.
As shown in Figure 5, present embodiment 2 is made up of locking bar 11, hook joint spare 12, connecting panel first 14 connecting panel second 13, spring 15 and flat gasket 16.Present embodiment spring 15 as different from Example 1 changes torsion spring into, end near hook joint spare 12 hinges is provided with spring eye 17, torsion spring 15 just is contained in this spring eye, and this torsion spring is enclosed within outside the hinge 18 of hook joint spare 12, also changes the T jacket of embodiment 1 into flat gasket 16 in addition.All the other are identical with embodiment 1.
