Abstract

The present invention is an improved quick dismantling structure of bicycle that allows the quick dismantling screw to have better practical efficacy. Mainly, the assembled structure of the screw rod and the locking/packing stem is that the locking/packing stem has a concave slot to form two connection parts. A forcing sleeve and the connecting head of the screw rod are assembled in the concave slot. The connection part has the assembling hole and the through hole. The connecting block and the driving shaft penetrate into and are assembled in the assembling hole. The connecting block has the eccentric hole to assemble the linking shaft of the driving shaft. With the aforementioned structure, the effect of increasing the locking/packing force can be formed to obtain extremely stable locking/ packing. Furthermore, it has the effects of fast operating, and smooth and balance during the locking/packing rotation.

Description

Bicycle quick release structure improvement

This creation is a bicycle quick release structure improvement, which makes the bicycle quick release screw have smooth operation, and has to increase the locking force to achieve a more stable locking effect.

Inspect, the quick-disassembling screw structure of the conventional structure is generally shown in Figures 1, 2 and 3. The screw 10 is provided with a nut 18 at one end, the connecting head 11 and the forced sleeve 12 at the other end, and the forced sleeve 12 is hollow. The combination has a combination hole 13 in which the drive shaft 14 is assembled. The drive shaft 14 has an eccentric shaft 15 coupled to the connector 11 of the screw 10, and the other side of the drive shaft 14 is fitted with a bolt 17 to form a lock lever 16. Its function: when the rotation locks the handle 16, the drive shaft 14 and the eccentric shaft 15 can be interlocked, and the forced sleeve 12 is forced to move to achieve the effect of locking or relaxing; the above structure has the following disadvantages: (1) As shown in FIG. 1 and FIG. 3, it is set as the forcing sleeve 12 has only one locking handle 16 on the side, so the strength of the locking handle 16 is small, and the locking force generated is small (2) as shown in FIG. The locking handle 16 is on the side of the forcing sleeve 12, and is not in the center position of the forcing sleeve 12. Therefore, when the rotation is locked, the screw is "eccentric", so the balance is poor and the force is not smooth.

The present invention is to improve the above-mentioned conventional shortcomings. The main technology and purpose are as follows: the locking handle is provided with a groove and two connecting portions, and the two connecting portions are provided with a combined hole. The connecting sleeve of the pressing sleeve and the screw is combined in the groove, the two connecting portions are sleeved on both sides of the pressing sleeve, the connecting block of the connecting portion is provided with a connecting block, the connecting block has an eccentric hole, and the eccentric hole of the two connecting blocks is combined with the driving shaft The linkage shaft forms a screw, a forced sleeve, and a locking handle. The strength of the endurance is increased by the two connecting portions, and the locking force can be increased, and the two connecting portions can be applied in the same straight line as the screw, so that the balance of the force is good, and the rotation can be smoothly and quickly. Complete the lock and relax.

Referring to Figures 4, 5, 6, and 7, a screw 20 has a nut 26 at one end and a connector 21 and a forced sleeve 22 at the other end. The force sleeve 22 is hollow and has a combined hole 23 for penetration. The connecting sleeve 22 is provided with a connecting shaft 21 of the driving shaft 24 and the screw 20; the driving shaft 24 has a connecting shaft 25 at both ends thereof for the combined locking handle 30; the locking structure 30 and the interlocking shaft 25 and the forced sleeve 22 are combined. The locking handle 30 has a recess 310 and is formed with two connecting portions 31. The two connecting portions 31 are provided with a combined hole 32 and a through hole 33. The two connecting portions 31 are sleeved on both sides of the pressing sleeve 22, and the connecting portion 31 is The connecting hole 34 is provided with a connecting block 34, and the connecting block 34 is provided with an eccentric hole 35 for combining the connecting shafts 25 of the driving shaft 24, and the locking head 30, the driving shaft 24, the pressing sleeve 22, and the connecting head 21 of the screw 20 are connected. In one piece, the connecting block 34 is provided with a screw hole 36, and the bolt 37 is engaged with the through hole 33 of the connecting portion 31 of the locking handle 30 and the screw hole 36 of the connecting block 34 to prevent the connecting block 34 from coming off.

With the above structure, the following effects and effects can be obtained:

(1) As shown in Figures 4 and 5, the lock handle 30, and Figures 6 and 7, the lock handle is provided with two joints 31. When the lock is to be locked and relaxed, the lock is rotated. The forcing handle 30 forms the two connecting portions 31 to simultaneously operate, and the two connecting blocks 34 are rotated, and the interlocking shaft 25 and the driving shaft 24 are rotated by the eccentric hole 35, that is, the forced sleeve 22 can be locked and relaxed. . The structure of the two connecting portions 31 and the two connecting blocks 34 has the effect of high endurance strength, so that a large locking force can be obtained, and the locking effect can be further stabilized.

(2) As shown in Fig. 7, the two connecting portions 31 of the locking handle 30 are in line with the screw 20, so that when the rotation force is rotated, a better balance effect can be obtained, and the rotation is smoother, and thus the comparison can be made. The effect of labor-saving locking.

(3) As shown in Fig. 5, the connecting block 34 is incorporated in the combined hole 32 of the connecting portion 31 of the lock lever 30 to form an "embedded combination", and the effect of high endurance is obtained.

In summary, the structure of this creation does have excellent practicality and enhanced efficiency, and it is in line with the new patent principle, so please grant a patent.
