Description
Technical field
The utility model relates to a kind of folding joint, especially for the folding joint of folding bicycle handlebar vertical tube.
Background technology
Folding joint is widely used in the folding bicycle, usually realize its fixed function by a pair of connecting panel that is hinged, as shown in Figure 1, mostly existing folding bicycle vertical tube folding joint is that an end is by lower adaptor on the hinge axis hinge, the other end is provided with latching device, and latching device is positioned at the grip.Hinge axis and latching device are oppositely arranged, and because of the locking device structure complexity, outstanding fully folding joint is subject to collision and causes distortion, and monnolithic case is also relatively poor.
Summary of the invention
Technical problem to be solved in the utility model is to provide a kind of latching device to be positioned at the folding joint that the joint in-to-in is used for folding bicycle handlebar vertical tube.
In order to solve the problems of the technologies described above, the technical solution adopted in the utility model is: a kind of folding joint that is used for folding bicycle handlebar vertical tube, comprise with hinge axis bonded assembly top connection and lower adaptor, handle and eccentric wheel are housed on the hinge axis, eccentric wheel sleeve one adapter sleeve, the hinged sliding shoe of adapter sleeve, sliding shoe moves forward and backward in the supporting base of the inner cap inboard of being fixed in folding joint, sliding shoe links to each other with interior V-arrangement shape clamping block by a screw rod, the top connection and the lower adaptor outside in a relative side with hinge axis are formed with, outer V-arrangement shape groove after the lower adaptor closure, by adapter sleeve, sliding shoe, supporting base, the latching device that screw rod constitutes is positioned in the space that forms after top connection and the lower adaptor closure, interior V-arrangement shape clamping block is positioned at the outside after top connection and the lower adaptor closure, and is stuck in the outer V-arrangement shape groove and locks, open and close top connection and lower adaptor.
Described supporting base is fixed in the inner cap inboard of top connection, and interior V-arrangement shape clamping block is positioned at the side-prominent last card base of top connection one, and one side-prominent following card base is long than being positioned at lower adaptor.
Be formed with a circle ring stiffener at the outside of lower standing tube, the downside of lower adaptor, be formed with the toroidal cavity that is used to hold front fork nut and front fork assembly between ring stiffener and the lower standing tube.
The height of described ring stiffener is that the bottom face of ring stiffener just in time rides on the front fork assembly.
The beneficial effects of the utility model are: latching device is positioned at joint inside, causes distortion with crash-avoidance, also makes the joint profile more attractive in appearance.

Fig. 2 is the folding joint structural representation that the utility model is used for folding bicycle handlebar vertical tube.
Fig. 3 is the folding joint Unclosing structure scheme drawing that the utility model is used for folding bicycle handlebar vertical tube.
Fig. 4 is the section-drawing that the utility model is used for the folding joint of folding bicycle handlebar vertical tube.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is described in further detail:
As Fig. 2,3, shown in 4, the utility model is used for the folding joint of folding bicycle handlebar vertical tube, comprise with hinge axis 1 bonded assembly top connection 2 and lower adaptor 3, handle 4 and eccentric wheel 5 are housed on the hinge axis 1, eccentric wheel 5 overcoats one adapter sleeve 6, adapter sleeve 6 hinged sliding shoes 7, sliding shoe 7 moves forward and backward in the supporting base 10 of the inner cap inboard of being fixed in folding joint, sliding shoe 7 links to each other with interior V-arrangement shape clamping block 9 by a screw rod 8, be formed with the top connection 2 and lower adaptor 3 outsides of hinge axis 1 a relative side, outer V-arrangement shape groove 20 after the lower adaptor closure, by adapter sleeve 6, sliding shoe 7, supporting base 10, the latching device that screw rod 8 constitutes is positioned in the space of top connection 2 and lower adaptor 3 closed back formation, interior V-arrangement shape clamping block 9 is positioned at the outside after top connection 2 and lower adaptor 3 closures, and is stuck in locking in the outer V-arrangement shape groove 20, open and close top connection 2 and lower adaptor 3.
Described supporting base 10 is fixed in the inner cap inboard of top connection 2, interior V-arrangement shape clamping block 9 is positioned at top connection 2 one side-prominent last card bases 21 and grows than being positioned at lower adaptor 3 one side-prominent following card bases 22, when folding joint was opened, interior V-arrangement shape clamping block 9 can not break away from top connection 2.Be formed with a circle ring stiffener 11 at the outside of lower standing tube 12, the downside of lower adaptor 3, be formed with the toroidal cavity that is used to hold front fork nut and front fork assembly between ring stiffener 11 and the lower standing tube 12.The height of described ring stiffener 11 is that the bottom face of ring stiffener 11 just in time rides on the front fork assembly.
Folding joint of the present utility model, eccentric wheel 5 rotates together during turning handle 4.Eccentric wheel 5 overcoats one adapter sleeve 6, adapter sleeve 6 hinged sliding shoes 7, sliding shoe 7 links to each other with interior V-arrangement shape clamping block 9 by a screw rod 8.Sliding shoe 7 is limited in moving forward and backward in the supporting base 10. and sliding shoe 7 moves forward and backward and just drives clamping block 9 and move forward and backward, thus chucking or unclamp the fit outer V-arrangement shape groove 20 of back formation of lower adaptor.By adjusting screw(rod) 8 length, the size of scalable coupling mechanism force.Be formed with a circle ring stiffener 11 at the outside of lower standing tube 12, the downside of lower adaptor 3, be formed with the toroidal cavity that is used to hold front fork nut and front fork assembly between ring stiffener 11 and the lower standing tube 12.The height of described ring stiffener 11 is that the bottom face of ring stiffener 11 just in time rides on the front fork assembly.Make folding joint of the present utility model, more attractive in appearance with the vehicle frame head pipe profile that is connected as a single entity.Because of the area of contact increase of front fork assembly and lower adaptor bottom, thereby increase bearing force, make vertical tube intensity and rigidity advance a raising.
The above only is a preferred implementation of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also should be considered as protection domain of the present utility model.
