Abstract

The present invention is a high-strength quick-dismounting screw rod structure which can provide an enhanced locking forcing to the quick dismount screw rod; main characters are: both sides of driving shaft of screw rod are equipped with linking shaft and lock forcing handles are arranged on the both linking shafts with an eccentric hole sepesrtly. Two lock forcing handles are abutted each other to integrate as a whole and the enduration strength can be enhanced by the integrated dual handles and forms the effect of lock forcing enhancement thus a more stable lock forcing effect can be achieved. The better locking effect can be achieved during the rotation of lock forcing handles and becomes more smoothly, quick locking.

Description

High-strength quick-release screw structure

The invention is a high-strength quick-release screw structure, which makes the locking force of the quick-disconnecting screw increase the endurance strength and improve the balance during the rotation, thereby generating the effect of increasing the locking force, so that the locking force is more stable.

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 invention is to improve the above-mentioned conventional disadvantages, and the main technical and purpose is that the locking handle is provided in two, which are respectively arranged on two sides of the pressing sleeve, and the two locking handles are combined and integrated by two locking handles. It is necessary to increase the strength of the endurance, and then the locking force can be increased, and after the two locking handles are integrated, the force can be applied in the same straight line as the screw, and the force balancing effect is good.

Referring to Figures 4, 5 and 6, a screw 20 has a nut 30 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, which is in the sleeve 22. A drive shaft 24 is provided, and the drive shaft 24 is combined with the joint 21 of the screw 20. The drive shaft 24 is provided with a linkage shaft 25 at both ends, and the two linkage shafts 25 are respectively provided with lock handles 26 and 27, and the two lock handles 26 and 27 are respectively provided. The mating bolts 29 are integrally assembled, and the two locking levers 26 and 27 are provided with eccentric holes 28.

With the above structure, the following functions and advantages can be obtained:

(1) As shown in Figures 4, 5, and 6, the two locking arms 26 and 27 are integrally connected. When the locking handles 26 and 27 are rotated, the rotating shaft 24 and the interlocking shaft 25 are rotated. Set the 22 action to achieve the effect of locking and relaxing. However, by using two locking handles 26, 27, the endurance strength can be increased, so that a large locking force can be withstood to achieve a more stable locking effect.

(2) As shown in Fig. 6, the two integrated lock levers 26, 27 can be in line with the screw 20, so when the force is applied to rotate the lock handles 26, 27, the balance is better. The rotation is smoother and thus it is easier to lock.

In summary, the structure of the present invention does have excellent practicality and enhanced efficacy, and is in line with the gist of the invention patent, and is therefore required to grant a patent.
