Description

Folding joint

Technical field

The utility model relates to the folding accessory technical field of folding bicycle frame and handlebar.

Background technology

In the folding joint that existing folding bicycle uses, what lockout mechanism was used morely is the quick detach assembly that is made of eccentric wheel handle, this lockout mechanism is located at the joint side, it is indecency to protrude a bulk of outward appearance, and a kind of folding joint of inner locking type has appearred in recent years, this folding joint is exposed at except handle outside the joint outside, all the other latch fittings are all at the joint middle part, outward appearance is more attractive in appearance, for example the latch hook of the folding joint showed of China Patent No. 200920302059.0 connects two and pulls when closing up and can retreat automatically, close up and to buckle into locking two connecting panels when putting in place automatically, rotate eccentric wheel handle then and can prevent that latch hook from retreating, but this folding joint structure is complicated, assembling is difficult, the manufacturing cost height, in addition, the latch hook of this folding joint and connecting panel bonded assembly hinge are on the outside face of connecting panel, in the time of on being soldered to vehicle frame or handlebar, articulation piece all wraps in the pipe, is not easy to maintenance when articulation piece has fault.

Summary of the invention

The purpose of this utility model just provides a kind of simple in structure, easy and simple to handle, safe in utilization, folding joint that outward appearance is graceful, easy to installation and maintenance.

In order to address the above problem, the scheme that the utility model adopts is to include an end by interconnective connecting panel first of hinge and connecting panel second, and locking bar, described locking bar is installed on part in two holes of described connecting panel first by the latch hook that has been threaded, the part of described latch hook stretches into and is used to limit in the guide groove of described latch hook rotation on the described connecting panel first, described connecting panel second is provided with the lock platform that hooks for described latch hook, stretch out outside the described connecting panel first outer end of described locking bar, is equipped with between described connecting panel first and described locking bar the spring of described latch hook to described lock platform directive effect.

In such scheme, handwheel can be installed, between described connecting panel first and described handwheel, be provided with the shaft shoulder of external diameter on the described locking bar greater than described the above locking bar mounting hole of connecting panel first in the end of described locking bar outer end; On described hinge, can be hinged with the eccentric wheel of a band handle over against place, described locking bar end.

Owing to adopted such scheme, the utility model compared with prior art has following beneficial effect:

1, because locking bar and latch hook adopt is threaded, latch hook just can not retreat when the handwheel of locking bar is threaded to the shaft shoulder of locking bar and connecting panel side and offsets, has auto-lock function and be threaded, therefore need not security insurance mechanism has been set again, operate very simple, the latch fitting of adding whole folding joint only has a less handwheel to expose, compact conformation, and outward appearance is small and exquisite.2, in addition by locate the eccentric wheel of a hinged band handle over against the locking bar end on hinge, the eccentric wheel rim part props up the locking bar end face, also can reach the purpose that makes latch hook portion pusher, and installation and maintenance are all very convenient.

The specific embodiment

Below in conjunction with the accompanying drawing example structure of the present utility model is described in further detail:

Embodiment one:

As Fig. 1,2,3,4, shown in 5 and 6, present embodiment one includes an end by hinge 6 interconnective connecting panel first 2 and connecting panel second 1, and locking bar 3, side at the other end of connecting panel first 2 is provided with hole 2.3, in connecting panel first 2, be provided with limiting section, on limiting section, be provided with hole 2.1, the inner of locking bar 3 is installed in hole 2.3 and the hole 2.1, on locking bar 3, be connected with a latch hook 4 by screw thread 3.3, the part of latch hook 4 stretches into to be opened in and is used on the connecting panel first 2 limit in the guide groove 2.2 of latch hook 4 rotations, guarantees that latch hook 4 can only move axially along locking bar 3 when locking bar 3 rotations.The hook of latch hook 4 is partly with inclined-plane 4.2, is provided with the lock platform 1.1 that hooks for latch hook 4 on connecting panel second 1, and lock platform 1.1 is provided with guiding surface 1.2, when inclined-plane 4.2 inserts the locking of lock platform 1.1, two connecting panels.On locking bar 3, be provided with groove 3.4, in groove 3.4, snap in snap ring, between snap ring and hole 2.1, be set with spring 5 in locking bar 3 the inners as the step position, this spring 5 with described latch hook 4 to lock platform 1.1 directive effects.The outside of connecting panel first 2 is stretched out in the outer end of locking bar 3, in the end of outer end handwheel 3.1 is installed, and is being provided with the shaft shoulder 3.2 of external diameter greater than the mounting hole 2.3 that is positioned at locking bar 3 on the connecting panel first 2 on the locking bar 3 between connecting panel first 2 and handwheel 3.1.

The present embodiment setting-up procedure is: locking bar 3 passes hole 2.3 and enters in the connecting panel first 2, passes the tapped bore 4.1 of latch hook 4 again, and the spring 5 of packing into passes in the connecting panel first 2 limiting section holes 2.1 again, and the snap ring of the opening of packing in groove 3.4 at last gets final product.

Embodiment two:

As shown in Figure 7, present embodiment is made of connecting panel first 12, connecting panel second 11, locking bar 13, latch hook 14, spring 15 and hinge 16, this example is used for vehicle frame and except the shape appropriate change with connecting panel first 12, connecting panel second 11, all the other structures are identical with embodiment one in order to adapt to.

Embodiment three:

Present embodiment is made of connecting

panel

21,22, locking bar 23, latch hook 24, spring 25, hinge 26 and eccentric wheel 27, the stage casing that the difference of present embodiment and embodiment one is two connecting panel bonded assembly hinges 26 is hinged with an eccentric wheel 27 that has a handle over against place, locking bar 23 ends, and there is a breach at connecting panel second 21 corresponding positions, locking bar 23 end faces do not have the handwheel and the shaft shoulder in addition, and it prevents that latch hook from retreating and props up the locking bar end face by eccentric rim and reach.

The locking bar of the utility model folding joint embodiment one and embodiment two and latch hook adopt and are threaded, latch hook just can not retreat when the handwheel of locking bar is threaded to the shaft shoulder of locking bar and connecting panel side and offsets, has auto-lock function and be threaded, therefore need not security insurance mechanism has been set again, operate very simple, the latch fitting of adding whole folding joint only has a less handwheel to expose, and outward appearance is coordinated grace very much.

The locking bar of the utility model folding joint embodiment three and latch hook also are to adopt to be threaded, but do not have the handwheel and the shaft shoulder on the locking bar, and it prevents that latch hook from retreating is that eccentric rim by handle props up the locking bar end face and reaches.
