Description
Technical field
The utility model relates to the lock device field of folding accessory, is specifically related to a kind of self-locking device of folding joint.
Background technology
Along with modern people go on a journey custom change, the advantage more and more welcomed by the peoples such as folding vehicle is little, lightweight with its volume, be easy to carry, folding vehicle function is many, annex is many, design design is complicated, in order to reach desirable folding effect, often take loaded down with trivial details structure and multiple control step.In prior art, fold mechanism and locking release mechanism adhere to different constructing modules separately, and first design fold mechanism, then increase lockout mechanism on fold mechanism basis, the design original intention having run counter to folded products makes finished product bloatedness.In addition, people require also very high for the convenience that folding vehicle is folding, and the too loaded down with trivial details meeting of multiple control step makes operator lose patience, and reduces the laminating degree of products and marketing; In addition, folded state or deployed condition all need higher locking firmness, to ensure safety.
Consider the requirement of folding and expanding locking integration, Vehicles Collected from Market is needed one " folded lock one " formula badly and is folded the vehicle.
Summary of the invention
The technical matters that this patent will solve is: the self-locking device designing a kind of folding joint, realizes locking and the unblock of folding joint.
This patent will solve the problems of the technologies described above adopted technical scheme: the self-locking device designing a kind of folding joint, it is characterized in that, between folding shaft and folding axle sleeve, gear is set, the lock pin using fixing spring fixing inserts gear through axle sleeve, described lock pin is provided with rotatable annular sleeve, described annular sleeve is provided with the bayonet socket for the lock pin that locks, folding shaft is arranged at chassis, folding axle sleeve connects after poppet, described lock pin comprises stock neck and an insertion end, accordingly annular sleeve is set at stock neck, the active strokes of the depth distance restriction lock pin retraction of described bayonet socket, described spring is provided with the bolt of adjusting elasticity, hollow bolt is inserted in described lock pin one end, hollow bolt is connected with spring, lock pin and the distance restraining spring at the bottom of hollow bolt hole adjust the active strokes of degree of tightness.Described annular sleeve arranges handlebar, and the neck of described handlebar arranges damping seal cover, and its manipulatable end stretches out beyond damping seal cover.
The beneficial effect that this patent has is: application the utility model can realize locking and the unblock of folding joint.Structure simply, realizes folded lock one, folds manipulation end when putting in place and realizes locking, when launching to put in place, manipulation end realizes locking again, and need not design blocking device in addition, structural strength is high, locking firmness is good, greatly reduces operation annex and program, practical.Described spring is provided with the bolt of adjusting elasticity, as the bolt is tightened spring force increase, when loosering a bolt spring force reduce, thus control lock pin insert gear time resistance size.The neck of described handlebar arranges damping seal cover, and its manipulatable end stretches out beyond damping seal cover, and seal closure can be dust-proof, can prevent again manipulatable end disorderly pendulum, play the effect of fixing manipulatable end.Hollow bolt is inserted in described lock pin one end, and the internal holes of hollow bolt plays the effect to lock pin location, and internal holes is reserved with stroke and bolt can not be hindered again to adjust degree of tightness, designs ingenious.

In figure: 1 folding shaft 2 folds axle sleeve 3 gear 4 fixing spring 5 lock pin 6 annular sleeve 7 bayonet socket 8 stock neck 9 insertion end 10 handlebar 11 damping seal cover 12 manipulatable end 13 hollow bolt 14 after poppet 15 chassis.
Detailed description of the invention
As shown in the figure, a kind of self-locking device of folding joint, gear 3 is set between folding shaft 1 and folding axle sleeve 2, the fixing lock pin 5 of fixing spring 4 is used to insert gear 3 through axle sleeve, described lock pin 5 is provided with rotatable annular sleeve 6, described annular sleeve 6 is provided with the bayonet socket 7 for the lock pin that locks, folding shaft 1 is arranged at chassis 15, folding axle sleeve 2 connects after poppet 14, described lock pin 5 comprises a stock neck 8 and insertion end 9, accordingly annular sleeve 6 is set at stock neck 8, the active strokes of depth distance restriction lock pin 5 retraction of described bayonet socket 7, described spring is provided with the bolt of adjusting elasticity, hollow bolt 13 is inserted in described lock pin 5 one end, hollow bolt 13 is connected with spring, lock pin 5 adjusts the active strokes of degree of tightness with the distance restraining spring at the bottom of hollow bolt 13 hole.Described annular sleeve 6 arranges handlebar 10, and the neck of described handlebar 10 arranges damping seal cover 11, and its manipulatable end 12 stretches out beyond damping seal cover 11.
During deployed condition, lock pin 5 inserts gear 3 between cog, and annular sleeve 6 withstands lock pin 5 from behind, and lock pin 5 cannot move backward, and after poppet 14 and chassis 15 lock together, and driver can set foot on vehicle and ride.When needs stored collapsed, rotate manipulatable end 12, be fixedly connected with operating side 12 or one annular sleeve 6 rotate thereupon, in annular sleeve 6, set bayonet socket 7 turns to lock pin insertion end position thereupon, the depth distance of bayonet socket 7 provides the active strokes of lock pin insertion end retraction, when now rotation after poppet 14 folds, pinion rotation makes every effort to overcome the elastic force taking spring set by lock pin 5, lock pin 5 each tooth on gear 3 slips over successively, when folding putting in place, again rotate manipulatable end 12, bayonet socket 7 is rotated and departs from original position, lock pin insertion end cannot retreat, again insert the between cog of gear 3, after poppet 14 and chassis 15 lock and cannot open.
Launched by folded state, again rotate manipulatable end 12, control bayonet socket 7 relative with lock pin insertion end, now then after poppet 14 and chassis 15 can be done and launched to move, and rotate manipulatable end 12 equally and make bayonet socket 7 change in location thus lock after poppet 14 and chassis 15 when expansion puts in place.
Locking and the unblock of folding joint can be realized, structure is simple, realize folded lock one, fold manipulation end 12 when putting in place and realize locking, when launching to put in place, manipulation end 12 realizes locking again, need not design blocking device in addition, structural strength is high, and locking firmness is good, greatly reduce operation annex and program, practical.Described spring is provided with the bolt of adjusting elasticity, and spring force increases as the bolt is tightened, and when loosering a bolt, spring force reduces, thus controls the size of resistance when lock pin 5 inserts gear 3.The neck of described handlebar 10 arranges damping seal cover 11, and its manipulatable end 12 stretches out beyond damping seal cover 11, and seal closure can be dust-proof, can prevent again manipulatable end 12 disorderly pendulum, play the effect of fixing manipulatable end 12.Hollow bolt 13 is inserted in described lock pin 5 one end, and the internal holes of hollow bolt 13 plays the effect of locating lock pin 5, and internal holes is reserved with stroke and bolt can not be hindered again to adjust degree of tightness, designs ingenious.
The utility model structure is simple, and novel in design, cost is low, efficiency is high, is applicable to volume production and popularization.
It is to be noted; above-mentioned embodiment is only the utility model preferred embodiment; for those skilled in the art, under the prerequisite meeting utility model works principle, any equivalent or similar replacement all falls into protection domain of the present utility model.
