The specific embodiment

Embodiment: a kind of bicycle folder quick detach handle with safe locking device, it comprises two quick detach 1 that need fastening structure and articulate with structure, eccentric wheel 11 and handle 12 integrally formed quick detach, also be provided with a lock dog 2 and a control stalk 3 on the handle 12, handle 12 simultaneously forms the space 13 that supplies ccontaining lock dog 2 towards the fastening structure of need, lock dog 2 is articulated in the described space 13 by bearing pin 4, the axial line of bearing pin 4 and eccentric wheel 11 in the same way, be in the middle of the lock dog 2 hollow shape and lock dog 2 dorsad handle side be provided with a baffle plate 5, lock dog 2 is provided with boss 6 towards a side of handle, boss 6 elasticity push against in control stalk 3, described control stalk 3 one ends are for pressing moved end 31, the other end is a tail end 32, control stalk 3 can axial free movement and radial location be located in the described space 13, corresponding boss 6 positions are provided with the annular groove 33 that just can supply boss 6 to be embedded on the control stalk 3, control the rotational angle of lock dog 2 by moving axially control stalk 3; Corresponding lock dog 2 places are provided with an anchor fitting 7 on the described structure, and described anchor fitting 7 can snap in and emerge in lock dog 2; On 12 groups on handle during to the fastening structure of need, axially promote described by the moved end this moment again, boss 6 is embedded in the annular groove 33, contrarotation takes place lock dog 2 (is reset force, by being set, realizes torsion spring, be common technology, this example no longer describes in detail), anchor fitting 7 slips in the lock dog 2, then unclamps by the moved end, and control stalk 3 resets under action of the spring, described boss 6 detaches described annular groove 33 and pushes against in control stalk 3 surfaces, lock dog 2 is forced to take place forward rotation, and anchor fitting 7 just snaps in the lock dog 2 to deviate from, and realizes the locking to handle.

Lock dog 2 by the structure that bearing pin 4 is articulated in the described space 13 is: handle 12 extends to form biside plate towards the one side two edges of the fastening structure of need to structure, biside plate is perpendicular to eccentric axial line, biside plate and handle surround described space 13, lock dog 2 is passed in bearing pin 4 activities, and bearing pin 4 two ends correspondence respectively are connected on the biside plate.

Described control stalk 3 can axial free movement and the structure be located in the described space 13 of radial location be: described control stalk 3 is provided with first annular groove 34, control stalk 3 wore the through hole of handle biside plate, the inside circumference of one through hole is movable being embedded in first annular groove 34 just, and the width of first annular groove 34 is greater than the thickness of a described through hole inside circumference, the width limitations of first annular groove control stalk 3 axially movable positions, and guaranteed that control stalk 3 can not break away from handle.

Described anchor fitting 7 is a screw.

A sheathed extension spring 8 on the control stalk 3, extension spring 8 one ends are tightened in control stalk 3 tail ends, extension spring 8 other ends are tightened in handle near the medial surface of control stalk 3 by the moved end, control stalk 3 is axially moving by stressed back, moved end, extension spring makes control stalk 3 be returned to the original position of control stalk 3 under the state that does not stress, keep boss 6 to detach the state of described annular groove 33, certain similar resetting structure is a lot, and replaceable as extension spring is stage clip etc.

The position movable sleeve that bearing pin 4 activities are passed in the lock dog 2 is provided with sleeve pipe 9, when compressing sleeve surface for anchor fitting 7, sleeve pipe 9 rotates and anchor fitting 7 is snapped in the lock dog 2, friction force when rotation can reduce both and compresses, and anchor fitting 7 pushes against sleeve pipe 9 surfaces, makes handle lock regularly be unlikely to take place loosening.

This routine operating process is as follows: when stir handle rely on need fastening structure after, lock dog 2 on the handle is near anchor fitting 7, that presses control stalk 3 moves axially control stalk 3 by the moved end, make the annular groove that boss 6 on the lock dog 2 is aimed on the control stalks 3, lock dog 2 backward rotation under the torsion spring reset response makes boss 6 be embedded in the annular groove 33, this moment on the lock dog 2 baffle plate 5 since lock dog 2 rotate and and then rotate and away from anchor fitting 7 positions, continuing to pull handle makes anchor fitting 7 place lock dog 2, unclamp by the moved end, control stalk 3 is homing under extension spring 8 effects, boss 6 breaks away from annular grooves and controlled bar surface pushes, this moment, lock dog 2 generation forward rotation drive baffle plates 5 rotated together, push finish after lock dog 2 just can't rotate, be that anchor fitting 7 just can't be deviate from lock dog 2 under the blocking effect of described baffle plate 5, realize the locking of handle.
