Description
Technical field
The utility model relates to technical field of bicycles, especially a kind of joint for folding bicycle and electromobile frame and handlebar.
Background technology
In the folding joint that existing folding bicycle uses, what lockout mechanism was used morely is the Quick-dismantle component that is made of eccentric wheel handle, this lockout mechanism is located at the middle part of joint side, and for example the catch gear of Chinese patent application number 01219542.1 and Chinese patent application number 03223700.6 folding joint of showing locks two connecting panels with the folding joint that eccentric wheel handle consists of.This Quick-dismantle component that is consisted of by eccentric wheel handle, what have locking effect is exactly one 6 millimeters screw, if this folding joint is used for stressed very large folding stand, leaning on the application force of the screw of 6 millimeters of bars is not enough for its coupling mechanism force, and as easy as rolling off a log appearance when bicycle running is become flexible danger such as causing overturning because Quick-dismantle component unclamps to cause at the girder that connects front and back wheel; This structure also can be locked at folding joint and be occurred obvious clearance gap between aft end face in addition, if a little with being subject to slight downward pressure on the saddle of defeating folded bicycle, this clearance gap is just larger, make car owner's front and rear beam of the two connecting panels connection that is connected to folding joint form certain angle, front and back wheel is not travelled in the same direction during bicycle running, there is larger potential safety hazard, and shortens the service life of folding joint.
And the folding joint of other form, for example the catch gear of Chinese patent application number 02225922.8 folding joint of showing is locked folding joint with the middle part that a threaded push rod acts on the folding joint side, and also there are the problems such as coupling mechanism force deficiency in these folding joints.
The locking that above-mentioned folding joint is used for the small-wheel-diameter car still can, but be used for six-wheel car, for example on mountain bike and the battery-driven car, its coupling mechanism force is obviously inadequate, the present very rare major cause of bull wheel folded bicycle that Here it is.
Summary of the invention
Problem to be solved in the utility model provides a kind of folding joint of forced locking, to solve existing folding bicycle and battery-driven car folding joint locking insufficient strength, clearance gap occurs between the locking aft end face, causes the lower problem of safety.
In order to address the above problem, the technical solution of the utility model is: the folding joint of this forced locking includes connecting panel first and the connecting panel second that is connected by hinge axis, and the opposite side of the relative jointed shaft of described connecting panel second is hinged with a bending handle; Described connecting panel first and described bending handle have one to be provided with two locking wheels that its axis is parallel to described jointed shaft in the middle of the two, have been threaded connection two locking push rods on another part; Be in when amounting to lock-out state in described connecting panel first and described connecting panel second, two described locking push rod tops are crimped on respectively on the wheel face of two described locking wheels.
In the technique scheme, more specifically scheme can be: be equipped be used to the jam nut that locks described locking push rod height on the described locking push rod of each root.
In order to address the above problem, the technical solution of the utility model can also be: the folding joint of this forced locking includes connecting panel first and the connecting panel second that is connected by hinge axis, and the opposite side of the relative jointed shaft of described connecting panel second is hinged with a bending handle; A locking rotating shaft that is parallel to described jointed shaft is housed on the described bending handle, rotation set screw is housed in the described locking rotating shaft and drives the reduction torsion spring that described locking rotating shaft resets; Two locking push rods radially are installed in the described locking rotating shaft; Described connecting panel first is provided with latch recess at the relative back side of its face of amounting to, and is in described connecting panel first and described connecting panel second and amounts to and during lock-out state, the outer end of described locking push rod is crimped in the latch recess of described connecting panel first.
In the technique scheme, more specifically scheme can be: a side of described latch recess is provided with the obstacle of projection.
Owing to adopted technique scheme, the utility model compared with prior art has following beneficial effect:
The folding joint of this forced locking adopts the locking push rod to carry out the locking of two places, makes the coupling mechanism force of whole folding joint stronger, and the power of two places locking is more even, locks more firm; The gap that connecting panel first and connecting panel second are amounted between the rear two boards is less, and the end clearance seam is less, the safety that has improved whole folding joint.
