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 front connecting board is provided with a guide block with a slope on the side surface of the locking rod fixed with a transmission block moving along the slope. A spring supplying stress to the drive the locking rod to the locking hole direction is positioned between the front connecting board and the locking rod. 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 guide block on band inclined-plane is housed in the side of locking bar on the preceding connecting panel, be fixed with the drive block that can move on the locking bar, be equipped with between preceding connecting panel and the locking bar the spring of locking bar to the lockhole direction application of force along the inclined-plane.
Described folding joint is fixed with the top board that can touch drive block with the drive block corresponding position on the back connecting panel.
Folding joint described in the utility model, owing on the guide block inclined-plane is arranged, drive block compresses the inclined-plane under the spring force effect, drive 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 drive block is moved along the inclined-plane, drives locking bar and axially insert lockhole under the spring force effect; When joint was in locking state, the user only needed the backward rotation locking bar, and drive block is oppositely moved along the inclined-plane, and the drive locking bar overcomes spring force and withdraws from 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 open mode;
Fig. 3 is that drive block and incline position concern scheme drawing;
Fig. 4 is the incline position reference diagram.
The specific embodiment
The folding joint of folding bicycle, as shown in Figure 1, 2, back connecting panel 2 and preceding connecting panel 1 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.The guide block 4 on band inclined-plane 10 is housed in the side of locking bar 3 on the preceding connecting panel 1, and its inclined-plane 10 is surrounded on outside the locking bar 3.Inclined-plane 10 references by location can because of its inclined-plane 10 directions are opposite with Fig. 2, so Fig. 4 is not the present embodiment scheme drawing, only be done with reference to figure 4 in 10 positions, inclined-plane more clearly.Be fixed with drive block 5 on the locking bar 3, drive block 5 can 10 slips along the inclined-plane.Between locking bar 3 and the preceding connecting panel 1 spring 7 is housed, in the present embodiment for being enclosed within stage clip on the locking bar 3, on drive block 5 and the preceding connecting panel 1 between the knock hole 9.
Described folding joint is fixed with the top board 11 that can touch drive block 5 with drive block 5 corresponding positions on the back connecting panel 2.When wanting lock-on connection, connecting panel 1 and back connecting panel 2 before closing up, the top board 11 on the back connecting panel 2 withstands drive block 5, and drive block 5 10 is moved along the inclined-plane, drives locking bar 3 axial insertion lockhole 6 under the spring force effect.So only need close up preceding connecting panel 1 and back connecting panel 2, and joint is auto lock just, and the user need not to spur handle 8 drive locking bars 3 and rotates, and operates more convenient.
Described folding joint, 10 1 ends have platform 12 on the inclined-plane on the guide block 4, and when joint was opened, drive block 5 rested on the platform 12, avoided its 10 downslides along the inclined-plane.
