Description

A kind of folding joint device

Technical field

This utility model is related to folding joint, more particularly to a kind of folding joint dress that can apply to folding bicycle Put.

Background technology

Energy-saving and emission-reduction are all being advocated in the whole world, and China is undisputed bicycle big country.Folding bicycle is carried because of which Convenient, occupation of land space is little, it has also become a very important species in bicycle, and has the trend for becoming more and more popular.

Existing folding bicycle great majority can arrange folding joint in the middle part of vehicle frame at present, wherein there is two classes to account for absolutely mostly Number.The laterally folded bicycle of the first, folding joint jointed shaft are vertically arranged, vehicle frame front portion and vehicle frame rear portion in folding process Rotate up in the horizontal plane close up, for example Chinese patent CN201220473203.9 discloses " folding bicycle frame ", its Shortcoming is to close up operation to need large force, the little person of strength or girl to seem operating difficultiess when closing up or opening.It is another kind of It is longitudinal fold bicycle, the jointed shaft horizontal cross of folding joint is arranged, and for example Chinese patent CN201120278542.7 is public " Quickfolding bicycle " opened just belongs to this type, needs to mention vehicle frame front portion with vehicle frame rear portion in folding process Carry out closing up operation, it is relatively elaborate.

Utility model content

This utility model aims to provide a kind of folding convenient, laborsaving, while simple structure, easily fabricated folding joint dress Put.

What this utility model was realized in：A kind of folding joint device, including the first connecting plate, the second connecting plate, hinge Axle is articulated and connected through the first articulated section with the second articulated section, and first articulated section is arranged at the first connecting plate end, First connecting plate is divided into body and shell fragment by joint-cutting, and the shell fragment end protrudes from the first connecting plate side；The joint-cutting At the first articulated section to its axle center.

It is " L " type that the joint-cutting is located at the part of the first connecting plate.

First articulated section is hollow cylinder, and it is to be radially arranged that the joint-cutting is located at the part of the first articulated section.

First articulated section also has opening, and the opening is pointed at the hollow axle center in the first articulated section.

The opening tail end is also associated with otch, the otch and opening setting in a certain angle.

First connecting plate and the second connecting plate are additionally provided with locking device in the side relative with hinge.

The locking device is eccentric quick-detachment locking device.

First connecting plate and the second connecting plate are respectively fixedly connected with folding bicycle frame part.

This utility model folding joint device has shell fragment, when the piecing devices are closed, the second connecting plate compressing shell fragment A pretightning force can be produced, so that this folding joint device is locked tighter；In working order, the first connecting plate is connected with second Plate is also not easy to release.When the locking device of this folding joint is opened, the second connecting plate can be flicked a segment distance by shell fragment, from And cause opening procedure more smooth, laborsaving.

Specific embodiment

This utility model folding joint device is described in further details with reference to Fig. 1 to Fig. 6.

As shown in Figure 1, 2, it is this utility model folding joint exploded isometric figure, including the first connecting plate 1, the second connecting plate 2, hinge 3 is articulated and connected through the first articulated section 4 with the second articulated section 5.First articulated section 4 is arranged at the first connecting plate 1 end, the first connecting plate 1 are divided into body 11 and shell fragment 12 by joint-cutting 6, and 12 end of the shell fragment protrudes from the first connecting plate Side S；The joint-cutting 6 is at the first articulated section 4 to its axle center.

Such as Fig. 3, when the first connecting plate 1, the second connecting plate 2 close up, shell fragment 12 be located at the body 11 of the first connecting plate 1 with Between second connecting plate 2, as the 2 inner side surface pressure effect of the second connecting plate, shell fragment 12 are extruded rollback, 6 spacing of joint-cutting diminishes, End-state is that 11 medial surface of body of the first connecting plate 1 is fitted completely with 2 medial surface of the second connecting plate.It is more than from mechanical original Description in reason and mechanics principle.

It is " L " type that the joint-cutting 6 is located at the part 61 of the first connecting plate 1.First articulated section 4 is hollow cylinder, described to cut Seam 6 is located at the part 62 of the first articulated section 4 to be radially arranged.Shell fragment 12 is actually directly connected in the first articulated section 4, this to set Put rational elasticity can be reached while strength of joint is ensured.Further, during can be provided with the first connecting plate 1 Empty 43, to mitigate weight, while making shell fragment 12 that there is preferably resilience.

First articulated section 4 also has opening 41, and the opening 41 is pointed at the hollow axle center in the first articulated section；It is described 41 tail ends that are open are also associated with otch 42, the otch 42 and 41 setting in a certain angle of opening.Opening 41 with joint-cutting 6 to setting Put, it is therefore an objective to the appropriate rigidity for reducing the first articulated section 4, make shell fragment 12 that there is preferably resilience.

As shown in Figure 4,5, 6, first connecting plate 1 and the second connecting plate 2 are respectively fixedly connected with folding bicycle car The forward and backward part of frame.First connecting plate 1 and the second connecting plate 2 are additionally provided with locking device 7 in the side relative with hinge 3. The locking device 7 can be bolt type locking device, need by Wrench to open.The locking device 7 can also be inclined Heart quick-detachment locking device, which has quick-release handle, it is not necessary to instrument, can be easily accomplished opening manually by manpower or lock. The above-mentioned two kinds of locking devices enumerated are mechanical field usual means, do not do deep explanation.

Preferred embodiment of the present utility model is the foregoing is only, it is not to limit this utility model, all at this Any modification, equivalent and improvement made within the spirit and principle of utility model etc., should be included in this utility model Protection domain within.
