Abstract
The utility model discloses a folding joint for folding bicycle comprising a front connecting board and a back connecting board hinged on one side. The front connecting board is provided with a locking rod moving along the axle direction and the back connecting board is provided with a locking hole which can be plugged with the locking rod. The surface of the locking rod is provided with an inclined slope. The front connecting board is fixed with a guide block correspondingly moving along the slope. A spring conducting stress to the locking rod towards the locking hole direction is positioned between the front connecting board and the locking rod. After the front connecting board and the back connecting board are combined, the user only needs to rotate the locking rod to open or lock the joint. The operation is convenient, the structure is simple and the cost is reduced. Opening the locking rod needs the spring force and thus the locking rod inserting into the locking hole can not exist by jolting and thus the safety performance is good.
Description
Technical field
The utility model relates to the folding joint of folding bicycle.
Background technology
On the vehicle frame of folding bicycle folding joint is housed, generally realizes its fixed function by a pair of connecting panel that is hinged.The structure of fixed connecting plate has multiple, and the latching device that the shortage that has is firm unclamps when being subjected to external impacts easily, and the cyclist is caused danger; The complex operation step that has is made troubles to the user; The part that has is numerous, the inner structure complexity, and requirement on machining accuracy is very high, has increased builder's cost.
Summary of the invention
The purpose of this utility model provides a kind of simple in structure, easy to operate and folding joint that latching device is firm.
The folding joint of folding bicycle, be included in preceding connecting panel of a side pivotally attached and back connecting panel, before be equipped with on the connecting panel can axially movable locking bar, have the lockhole that can insert locking bar on the back connecting panel, the locking bar surface has the bevelled inclined-plane, be fixed with and be equipped with between preceding connecting panel and the locking bar the spring of locking bar along the guide block of inclined-plane relative displacement on the preceding connecting panel to the lockhole direction application of force.
Described folding joint is fixed with a piece on the locking bar, be fixed with the jacking block that can touch a piece with a piece corresponding position on the back connecting panel.
Folding joint described in the utility model, owing to have the bevelled inclined-plane on the locking bar, the inclined-plane compresses guide block under the spring force effect, guide block can be along the inclined-plane relative displacement.When joint is in open mode, connecting panel and back connecting panel before closing up, the user only needs rotating rod lock, and the inclined-plane of locking bar is relatively moved along guide block, drives locking bar and axially insert lockhole under the effect of spring force; When joint was in locking state, the user only needed the backward rotation locking bar, and the inclined-plane of locking bar is oppositely moved along guide block, drove locking bar and overcame spring force release lockhole.After preceding connecting panel and back connecting panel closed up, the user only needs action of rotating rod lock, can open or lock-on connection, and was easy to operate; Its simple structure has reduced cost; Because opening locking bar need overcome spring force, the locking bar that inserts in the lockhole can not withdraw from because of jolting, and safety is good.

Fig. 2 is the block diagram of folding joint locking state;
Fig. 3 is that guide block and locking bar incline position concern scheme drawing.
The specific embodiment
The folding joint of folding bicycle, as shown in Figure 1, 2, preceding connecting panel 1 and back connecting panel 2 are hinged, before be equipped with on the connecting panel 1 can axially movable locking bar 3, have the lockhole 6 that can insert locking bar 3 on the back connecting panel 2, locking bar 3 passes knock hole 9, and handle 8 is contained in locking bar 3 upper ends, can drive locking bar 3 and rotate.Locking bar 3 surfaces have bevelled inclined-plane 10, as shown in Figure 3, inclined-plane 10 is side wall surfaces of helix skewed slot, before be fixed with on the connecting panel 1 can be along the inclined-plane guide block 5 of 10 relative displacemenies, be fixed with guide block seat 5.1 on the connecting panel 1 before in the present embodiment, guide block 5 is packed in the guide block seat 5.1, and guide block 5 inserts in the skewed slots, contacts with inclined-plane 10.Be equipped with the spring 7 of locking bar 3 between preceding connecting panel 1 and the locking bar 3 to the lockhole 6 direction application of forces.
Described folding joint is fixed with a piece 4 below inclined-plane 10 on the locking bar 3, be fixed with the jacking block 11 that can touch a piece 4 with piece 4 corresponding position on the back connecting panel 2.Spring 7 is enclosed within on the locking bar 3, is stage clip in the present embodiment, between a piece 4 and guide block 5.When wanting lock-on connection, connecting panel 1 and back connecting panel 2 before closing up, the jacking block 11 on the back connecting panel 2 withstands and props up a piece 4, and locking bar 3 is rotated, and inclined-plane 10 moves along guide block 5 together with skewed slot, drives locking bar 3 and axially move insertion lockhole 6 under spring 7 power effects.Therefore connecting panel 1 and back connecting panel 2 before only need closing up, joint is auto lock just, and the user need not to spur handle 8 rotates locking bar 3, more convenient to operate.
Described folding joint, 10 bottoms have platform 12 on the inclined-plane on locking bar 3 surfaces, and when joint was in open mode, guide block 5 rested on the platform 12, avoided inclined-plane 10 to glide along guide block 5.
