Folding bicycle integrated quick release and release structure

The present invention relates to a quick release structure and a release structure of a folding bicycle seat tube, and particularly to a folding bicycle integrated quick release and release structure.

The quick release structure of the conventional folding bicycle seat tube is provided with a quick release structure 2 at the top end of the seat tube 12 inserted into the straight tube 11 of the frame, and the quick release structure 2 includes one of the top ends of the straight tube 11 as shown in the first figure. The C-shaped collar 10, the two ends of the C-shaped bundle ring 10 extend like the mouth-shaped half-position positioning members 13, 14 respectively, and the positioning members 13, 14 have a hole 15, 16 on each side; outside the positioning member 13 on one side By means of a pin shaft 17, the shaft hole of the ear piece on both sides of the tip end of the flip handle 27 is connected with the ring-shaped head end of a screw 20, and the screw 20 passes through the center hole of a round pad 21, and passes through the positioning member of the side. After the hole 15 of the 13 enters the middle of the positioning members 13, 14, passes through a washer 22 and a ferrule 24 and a spring 25 at the inner end of the release lever 23, and then passes through the hole 16 of the other side positioning member 14 to A nut 26 is locked, and a cam surface 28 is disposed on the outer end of the flip handle 27 so as to be opposite to the screw, so as to generate a cam surface 28 against the sleeve 21, the screw 20 is tightened, and the flip handle 27 is unwound. The clamping of the screw 20 is released to separate the positioning members 13, 14 such as the mouth-half, and the seat rod 12 can be pulled down on the straight tube 11 to adjust the position; 20, the washer 22, the release lever 23, and the spring 25 are sequentially inserted; in addition, as shown in the first A, the hook 29 provided on the release lever 23 is used as the joint head 18 on the roller frame 1. At the fitting groove 19; the roller frame 1 can be rotated by the roller frame 1 after the hook 29 on the release lever 23 of the fitting groove 19 is opened; because the assembly of the components on the screw 20 is inconvenient, the disassembly is not even better. Convenience; in order to provide items that are more in line with actual needs, the creator conducts research and development to solve the problems that are easy to use in the conventional use.

The main purpose of this creation is to provide a folding bike integrated quick release and The releaser structure can form a set of components by extending the two ends of the C-shaped collar on the straight tube of the frame, such as a mouth-shaped half-point positioning member, to facilitate the passage of the screw during assembly; The special ring of the releaser makes it easier to release directly from the top, and can be used directly without searching.

In order to achieve the above purpose, the structure of the present invention has a long sleeve and a short sleeve, and one end of the long sleeve has a flange on the outer surface for one end of the spring, and the other end of the spring is inserted into a release. At the edge of the ferrule of the center, the long sleeve passes through the spring and the ferrule and is inserted into the short sleeve; the long sleeve and the short sleeve set are placed at the ends of the C-shaped bundle ring to extend the position like a mouth-to-half In the piece; each of the two sides of the positioning member has a hole; after a screw passes through the center hole of a circular sleeve, the hole inserted into one side of the positioning member passes through the hole in the long sleeve to the other side of the positioning member, and then the screw After passing through the round hole of one of the sleeves, the screw is connected with the screw hole of a fixing block, and the fixing block has a vertical perforation, and the vertical perforation of the fixing block is connected with the shaft hole of the ear piece on both sides of the tip end of the flipping handle by a pin shaft, One side of the fixing block has a locking hole for locking the hexagon socket screw, and a cam surface is provided correspondingly to the screw head to face the screw, so as to generate a cam surface against the square sleeve, the protruding point of the square sleeve against the long sleeve The end face of the long sleeve is tightened; the release device extends from the ferrule to a hook head, and the other Extending a loop in the opposite direction, the pressure loop can untie the restriction on the hook.

In order to enable your review committee to further understand the techniques, means and functions of this creation for the purpose of achieving the intended purpose, a better and feasible embodiment is presented, and the detailed description of the drawings is followed, and the purpose and characteristics of the creation are believed. And the advantages, when you can get a deep and specific understanding.

As shown in the second to eighth figures, the present invention provides a folding bicycle integrated quick release and release structure having a long sleeve 31 and a short sleeve 32. The end of the long sleeve 31 has a flange 33 on the outer surface. One end of a spring 34 is sleeved, and the other end of the spring 34 is inserted at the edge of the ferrule 36 at the center of a releaser 35. The long sleeve 31 passes through the spring 34 and the ferrule 36 and is inserted into the short sleeve 32; The long sleeve 31 and the short sleeve 32 are placed in the positioning member 13, 14 extending from the opposite ends of the C-shaped collar 10; the positioning members 13, 14 have a hole 15, 16 on each side; After a screw 37 passes through the center hole of a circular sleeve 39, the hole 16 inserted into the side of the positioning member 14 passes through the hole 15 in the long sleeve 31 to the other side of the positioning member 13, and the screw 37 passes through the sleeve. After the circular hole of the pad 39, the screw 37 is connected to the screw hole 41 of a fixing block 40. The fixing block 40 has a vertical through hole 42. The fixing block 40 is vertically perforated 42 by a pin 43 and the ears on both sides of the flipping handle 44 are provided. The shaft hole 45 is connected to each other, and a locking hole 46 is formed on one side of the fixing block 40 to lock the hexagonal screw 47. The front end of the flipping handle 44 is provided with a cam surface 48 corresponding to the screw 37. When the cam surface 48 is generated against the square pad 39, the protrusion 49 of the square pad 39 abuts against the end surface of the long sleeve 31 to cause the long sleeve 31 to be pulled outward. If the cam surface 49 is separated, the spring 34 will be long. The sleeve 31 is turned back; the releaser 35 extends from the ferrule 36 to a hook head 30, and the reverse direction extends out of a loop 3, and the buckle ring 3 can unravel the restriction of the hook head 30; the hook head 30 serves as a hook It is placed at the fitting groove 19 of the joint head 18 on a roller frame as shown in the eighth figure. When the ring 3 is located above, there is no restriction, and it is more convenient to unlock the action of the rear wheel frame.

In summary, the present invention uses a special design of the C-shaped collar 10 to integrate the inner sleeves 31 and a short sleeve 32, the spring 34 and the release lever 35 to form a single body. The effect of the C-shaped bundle ring 10 and the screw 37 and the fixing block 40 is well removed, and the effect of the direct release of the ring 3 specially provided by the release device 35 is more convenient, and can be directly used without searching, making it the easiest to understand. And implementation, so it can provide good usability and convenience, and is a completely different institution.
