The specific embodiment
The utility model is described in further detail below in conjunction with Figure of description:
As shown in the figure, last folded formation 5, following folded formation 1 are connected with the upward pipe/preceding pipe 20 of bicycle, following pipe/back pipe 21 by last pin 15, downside pin 18 respectively, also can be welded to connect.Last folded formation 5 one sides and last hinged cover 3, time hinged cover 4 and jointed shaft 2 hinged cooperations, jointed shaft 2 the other end and the screw 2a threaded of following folded formation 1 hinged cooperation by corresponding setting.Last folded formation 5, following folded formation 1 are that rotate mutually at the center with cardan axle 2, realize opening and closure function.Last folded formation 5 opposite sides are provided with the frid 9 of band chute 9a, be provided with between two frids 9 and slide up and down the lock shaft 7 that cooperates with chute 9a, the lock hook 8 of coaxial connection and its normal-running fit, quick detach handle 6 on the lock shaft 7, lock shaft 7 the other end and screw 7a threaded.The latch hook 17 of corresponding setting is fastened on lock hook 8 and the following folded formation 1, plays location and position-limiting action.Latch hook 17 inboards of following folded formation 1 are provided with the pothole 19 of indent, the pothole 19 handled easily persons of indent outwards open lock hook 8 with hand, at the breach that is provided with indent over against the following folded formation 1 outer rim place of lock hook 8 medial surfaces equally, make lock hook 8 when closure, just in time embed indentation, there, its profile is consistent, control position effect about promptly plaing prevents from again to collide with and comes off.Lock hook 8 can freely turn round, its two sides, top are provided with spring card slot 16 respectively, last folded formation 5 correspondence positions are provided with spring pin hole 12, the spoon shape position of spoon shape torsion spring 14 cooperates with spring card slot 16 clampings, the other end is plugged on location in the spring pin hole 12, and lock hook 8 is by spoon shape torsion spring 14, lock shaft 7 and last folded formation 5 elasticity normal-running fiies.The elliptic cam 6a that quick detach handle 6 is provided with by the bottom presses to touch with the locking pads 11 on being arranged on folded formation 5 and cooperates, be provided with on the last folded formation 5 of locking pads 11 belows and contact the micrometer adjusting screw 10 that cooperates with it, tapped bore 13 threaded that are provided with on micrometer adjusting screw 10 and the last folded formation 5, micrometer adjusting screw 10 can carry out micro-adjustment to the relative coupling mechanism force size of last folded formation 5, following folded formation 1.
The elliptic cam 6a that quick detach handle 6 is provided with by the bottom presses to touch with the locking pads 11 in two frids 9 and cooperates, can satisfy from lock face to the face of opening is the change in location of top dead point to the larger radius of curvature increase and decrease of bottom dead point more than 90 °, thereby drive lock hook 8 folded formation locking fast suddenly up and down, realize the purpose of main locking.For avoiding quick detach handle 6 to get loose automatically, the long axis that must guarantee the elliptic cam 6a of quick detach handle 6 lower ends in actual production is crossed the certain angle of its axle center median vertical line, that is: quick detach handle 6 from last pipe 20 to managing the setting range that has 21 more than 90 ° down.When pulling lock hook 8, lock hook 8 is that outwards rotate with respect to last folded formation 5 at the center with lock shaft 7, spoon shape torsion spring 14 produces torsion, thereby make lock hook 8 possess inside screen resilience all the time, realize the state that lock hook 8 and following folded formation 1 are close to all the time, not detaining for the second time and pulling work is to open folded formation up and down, realizes the secondary purpose that locks.
When the folding bicycle gathering is folding, operator's left hand is being held and is being managed 20 on the bicycle, then the right hand earlier with quick detach handle 6 from last pipe 20 downwards pipe 21 directions pull to lock hook 8 and stop about 90 ° the time, refer to reach down in the pothole 19 of folded formation 1 indent with big mother again, outside button is pulled lock hook 8 and is got final product to breaking away from latch hook 17.When needs are opened folding bicycle, operator's left hand is being held pipe 20 pipe 21 directions rotation downwards on the bicycle, supreme folded formation 5 contacts with following folded formation 1 inner end surface and stops, then the right hand quick detach handle 6 times that will be in open mode earlier by, the lock hook 8 and the latch hook 17 of following folded formation 1 are fastened fully, and reversing sense is pulled quick detach handle 6 and is gone to and manage 20 places and get final product again.This folder can be widely used in the folding positions such as handle, vehicle body and body of products such as bicycle, Electrical Bicycle, body-building apparatus and various tourisms, can adopt welding process to be connected with car body or body, generally adopt materials such as corrosion-resistant steel, carbon steel, aluminum alloy, magnesium alloy, titanium alloy or carbon fiber to make with non-welding process.
