Description
Technical field
The utility model relates to bicycle, in particular for the folding joint in the mountain bike vehicle frame, mountain bike can be folded.
Background technology
Pipe before the general bag of mountain bike vehicle frame, go up pipe, pipe and standpipe down, and constitute a leg-of-mutton vehicle frame by these pipes, in view of mountain bike needs high-intensity vehicle frame, so the vehicle frame of mountain bike generally is changeless.But development along with society, the expansion of the size of population and material, the space that people live is compressed gradually, therefore the application on the space seems especially important, traditional bicycle has not met the demand of current social development, therefore many manufacturers just drop into the research and development and the production of folding bicycle, and are the emergence that adapts to folding bicycle, and the folding joint supporting with it also is rapidly developed.But mountain bike is because the restriction of intensity, never having a suitable folding joint matches with it, cause the mountain bike of folded form to fail well to be developed, in order to be fit to the development of society, the mountain bike of folded form also will become the trend of development, therefore, the folding joint used of the suitable mountain bike of research and development becomes the matter of utmost importance that breaks through at present folding mountain bike development bottleneck.
Summary of the invention
Technical problem to be solved in the utility model provides a kind of folding joint that is used for two-fold mountain bike vehicle frame, and the Joint strenght height is convenient and fast connection, and suitable mountain bike vehicle frame is used.
For solving the problems of the technologies described above, the technical solution of the utility model is: a kind of folding joint that is used for two-fold mountain bike vehicle frame, comprise male end, female end and handle, described male end comprises that male end is connected pipeline section and male end linkage section, described female end comprises that female end is connected pipeline section and female end linkage section, one side of described male end linkage section and female end linkage section is hinged by bearing pin, the head end of described handle is articulated on the described bearing pin, described bearing pin below is provided with support platform in described male end linkage section or female end linkage section, and the head end of handle is eccentric wheel structure and is installed on the support platform; Described support platform is provided with perforation, be provided with connecting rod between described male end linkage section and the female end linkage section, described connecting rod one end is fixed on the bearing pin, the other end passes the perforation of described support platform and stretches out the outside of male and female end linkage section and nut links and connects, be provided with catching groove in the described nut button, the hinged relatively side of described male end linkage section is provided with public flange, the hinged relatively side of female end linkage section is provided with female flange, described male and female flange cooperates the formation clamp, and described clamp cooperates with the catching groove of described nut button.When the eccentric less rollover of handle head end forwards on the support platform, bearing pin is less apart from the distance of support platform, connecting rod is in movable state, because connecting rod and nut link and connect, connecting rod can be buckled nut the catching groove that nut is buckled to extrapolation and can not cooperate with clamp this moment, thereby fail to reach the locking clamp, male end linkage section and female end linkage section can rotate arbitrarily around hinge-point, and promptly folding joint is in released state.When the bigger rollover of handle head end off-centre forwards on the support platform, bearing pin becomes big apart from the distance of support platform, bearing pin pulling connecting rod makes connecting rod to a hinged side shifting, under the pulling of connecting rod, the nut button pushes on folding joint, make catching groove that nut buckles being buckled on the clamp tightly, because clamp comprises the flange of male end linkage section and the flange of female end linkage section, under the effect of nut button, limited the activity of male end linkage section and female end linkage section, and make the two fitting together tightly, i.e. the lock state of folding joint.
As improvement, the hinged side of described male end linkage section is provided with two male end mount pads, the hinged side of described female end linkage section is provided with two female end mount pads, described male end mount pad is located between described two female end mount pads, the head end of described handle is located between described two male end mount pads, and described bearing pin passes described male end mount pad, female end mount pad and handle head end.
As improvement, be with spring on the described connecting rod, described spring be located at that described nut is buckled and support platform between.When the eccentric less rollover of handle head end forwarded on the support platform, connecting rod was in movable state, and under the effect of spring, being flicked by spring of nut button nature makes the nut button separate with clamp.
As improvement, the binding face of described male end linkage section is provided with projection, and the binding face of described female end linkage section is provided with the depression that cooperates with described projection.The position of projection when male end linkage section and female end linkage section are fitted is more accurate, also can play the dislocation that brings owing to strenuous vibration when preventing male end linkage section and the applying of female end linkage section to a certain extent.
As improvement, the binding face of described male end linkage section and female end linkage section is inclined-plane or plane.Folding joint is located on the top tube and down tube of cycle frame, and the binding face of the folding joint of last pipe is the plane, and the binding face of the folding joint of following pipe is the inclined-plane, and so, the folding position of vehicle frame just can be on the vertical line.
As improvement, be equipped with storage tank on the binding face of described male end linkage section and described female end linkage section, described two storage tanks cooperate the formation passage, and described connecting rod passes described passage.
As improvement, described nut button comprises adjusting portion and connecting portion, and described adjusting portion is installed on the described connecting portion and forms described catching groove between adjusting portion and the connecting portion, and described connecting portion places described passage.The effect of connecting portion is that nut is linked an end that is connected on connecting rod on the one hand, is the translation of restriction nut button on the other hand.
As improvement, between described connecting rod and the connecting portion that described nut is buckled for being threaded.The rotation adjusting portion can change the length of connecting rod between connecting portion and bearing pin, makes connecting rod be in suitable length, can be too not tight when folding joint is locked, and can be too not loose when the folding joint release yet.
As improvement, the adjusting portion periphery of described nut button is provided with anti-skidding striped, makes things convenient for manual regulation.
As improvement, described catching groove edge is the inclined-plane, makes things convenient for clamp to enter in the catching groove.
The beneficial effect that the utility model is compared with prior art brought is:
Adopt the nut button to cooperate, can play good locking effect with the clamp of forming by male end linkage section flange and female end linkage section flange, and the Joint strenght height, convenient and fast connection, especially be fit to the mountain bike vehicle frame folding and use; The fit structure of nut button and clamp is simple, and it is little to take up room; Can change the length of connecting rod between connecting portion and bearing pin by the rotation adjusting portion, make connecting rod be in suitable length, can be too not tight when folding joint is locked, can be too not loose when the folding joint release yet.
