Handle with locking and safety devices for fast disassembling bicycle

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

technical field [0001] The invention relates to a quick release mechanism on a bicycle, in particular to a handle of a locking safety device on the quick release mechanism. Background technique [0002] Chinese Patent 200620068611.0 This structure of the folder is relatively compact in design from the surface, and it is more convenient to use. However, in the process of assembling and disassembling the folder, it relies on the quick release handle to fold the first pin and the second pin of the connecting shaft. The convex body of the positioning rod is fixed. Once it touches the quick release handle during exercise or is subjected to vibration during exercise, it will naturally loosen, and the first and second folding bodies will open naturally, which is very dangerous. [0003] Chinese patent 03223700.6 folder has a slope on the side corresponding to the notch in the second folding part, through the two slopes, the buckle part of the pin is pulled into the button hole by t...

Problems solved by technology

[0005] The present invention overcomes the defects that bicycle folders or quick release handles can be adjusted for tightness, but there is no safety device for the handle, and the handle has a safety device but cannot be adjusted for tightness. There is also a safety device structure with a cam. This structure includes a handle, a screw, a first pin, and also includes a handle eccentric cam, a handle hole, a handle safety block hole, and a safety block. The safety block includes a lock block, a spring hole, a spring, and a second pin. Pin, button, the screw includes screw, screw block, screw hole, compressed accessories, nut, the screw block also includes a lock hole, the handle and the screw are movably connected through the first pin, and an eccentric cam is set around the handle hole to ensure safety on the handle. One end of the block hole corresponds to the lock hole on the screw block. A safety block is arranged in the safety block hole of the handle. The lock block is provided with one end of the safety block. There is a hole on the safety block. The spring is placed in the safety block hole and is locked by the second pin. The handle, safety block and spring are connected as a whole. The safety block moves up and down in the safety block hole of the handle and automatically returns to its position under the action of the spring. The upper end of the safety block is provided with a button and fixed together. The lock holes on the block are correspondingly matched. There is one lock hole on the screw block, and several lock holes can also be set. The lock hole is a right-angle cut, and the cut matches the lock block. Tight attachment, when in use, after the eccentric cam on the moderate handle of the clamped attachment between the screw rod and the nut needs to be tightened, the safety block on the handle enters the locking block when the handle is pulled down and pressed. In the lock hole on the screw block, the handle cannot be moved without opening the button. Only after pressing the button on the handle, the lock block on the safety block leaves the lock hole on the screw block, and the screw block enters the notch on the safety block. Only then can the handle be pulled to release the compressed accessories
