Abstract

The invention relates to a handle with locking and safety devices for fast disassembling a bicycle, comprising a handle, a screw, a screw hole and pins, wherein an eccentric wheel is arranged on the handle, and the screw is moveably connected with the handle by the pins. The handle is characterized in that a safety block hole is arranged on the handle, a safety block is arranged in the safety block hole, a locking block is arranged on one end of the safety block, and a screw block is arranged on the screw and is provided with a locking hole matched with the locking block; a button is fixed onthe upper end of the safety block, a spring hole is arranged on the middle of the safety block and is provided with a spring, and the handle, the safety block and the spring are connected into a wholeby the pins; acted by the spring and the pins, the safety block is automatically returned; and when an accessory is tightly pressed by the eccentric wheel on the handle, the locking block on the safety block is led into the locking hole on the screw block, and the handle can only be pulled by pressing a button so as to cause the eccentric wheel on the handle to release the accessory. The handle has favorable safety and practicability, is suitable for the existing bicycle folder handle and the bicycle fast disassembly handle, greatly improves the safety of the bicycle during driving, preventsthe danger caused by handle looseness from occurring, has considerably simple structure and low manufacturing cost, and is applicable to the bicycle and an electric motorcar.

Description

The handle of a kind of bicycle quick-detaching tight safety device with lock

Technical field

Quick detach mechanism on a kind of bicycle of the present invention relates to the handle of locking safety device in the quick detach mechanism particularly.

Background technology

Chinese patent 200620068611.0 this structure folder design compact to the eye, use more convenient, but in the folder assembling and dissembling process, all rely on the quick detach handle by adapter shaft first pin, second pin will fold one, disome, position-limited lever convex body fix, in case run into the quick detach handle or on the go is vibrated in the motion, naturally loosening, folding one, disome is opened naturally, and the result is very dangerous.

Chinese patent 03223700.6 folder, establish on the corresponding side of breach in second folding part and to be provided with the inclined-plane, to sell by two inclined-planes and to establish button portion and pull by handle and enter button hole, reach security purpose, but handle is provided with cam, has pin-and-hole on the cam, and cam and connecting rod are built-in with pin by pin-and-hole, and cushion block effect around the connecting rod, handle down is wrenched, and the handle overhead cam strains at connecting rod in the effect of pin and pad, folder is fited, when handle boxed rod transfer pine, the handle overhead cam is stressed naturally little, the loosening naturally or disengagement of folder, button portion is with connecting rod, the rotation of handle and leave button hole, and project organization is very complicated.

200810033841.7 patents of my application, on folding handle and connecting rod, latching device is set, have the hole on this structure connecting rod two ends, one end is connected by pin with fixed mount, the connecting rod other end is connected by pin equally with handle, on connecting rod, have snap close, have the hole on the handle, be provided with safe block in the hole, but because reasons in structure, connecting rod is provided with screw thread can't transfer, can only rely on the connecting rod front end to be provided with rubber washer elasticity and lock folder, rubber period of service one elderization and losing efficacy, this structure still is the out of reach ideal effect, especially on the existing folder structure or can't use on other bicycle quick-detaching handle, or the out of reach ideal effect.

Summary of the invention

But the present invention has overcome bicycle folder or quick detach handle transfer degree of tightness, but there are not handle safety device and handle that safety device is arranged but can not the transfer degree of tightness and the defective that produces, the invention provides to be provided with and both had cam on the adjustable catcher handle of screw rod and also establish the safety device structure, this structure comprises handle, screw rod, first pin, also comprise the handle eccentric cam, handle hole, handle safe block hole, safe block, safe block comprises lock dog, spring eye, spring, second pin, button, comprise screw rod on the screw rod, the screw rod piece, screw hole, compacted annex, nut, also comprise lockhole on the screw rod piece, handle and screw rod flexibly connect by first pin, one week of handle hole is provided with eccentric cam, safe block hole one end is corresponding with lockhole on the screw rod piece on the handle, be provided with safe block in the safe block hole of handle, lock dog is provided with safe block one end, have the hole on the safe block, spring places in the safe block hole and by second to be sold handle, safe block, spring is connected as a single entity, safe block is up and down in the safe block hole of handle, and under action of the spring self-return, the upper end of safe block is provided with button and is fixed as one, the corresponding coupling of lockhole on lock dog on the safe block and the screw rod piece, the screw rod piece is provided with a lockhole, also several lockholes can be set, lockhole is a right angle incision, otch and lock dog are complementary, the other end of screw rod is established nut, the centre is provided with the annex that need compress, during use, after eccentric cam need compress leeway on the handle of clamped annex appropriateness between good screw rod of transfer of the present invention and the nut, when pulling lower handle and compress, lock dog enters on the screw rod piece in the lockhole on the safe block on the handle, under the situation of not opening button, can't pull handle, only behind the button of pressing on the lower handle, lock dog leaves lockhole on the screw rod piece on the safe block, the screw rod piece enters in the safe block upper notch, just can pull handle, compacted annex is discharged.The present invention is not only simple in structure, and be applicable to that various bicycle quick-detaching fixing device band eccentric cam handles or existing bicycle folder armrest handle eccentric cam compress and settle use, has extensive practicality, and improved safety and reliability greatly, prevented to cause producing higher threat because of the loosening holddown attachment member of handle discharges.
