Abstract

The present invention relates to a quick-release screw structure for providing the quick-release screw with a better practical effect. The quick-release screw structure is mainly a connection structure of a fastening handle and a screw rod, which is provided with a connector, a pivot head, and an inner connector, wherein the connector has an eccentric hole for being assembled with the pivot head, the connector is further provided with an assembling hole for being assembled with a reinforcing connector, and the inner connector has a screw hole for being assembled with the fastening handle. A reinforcement effect can be formed via the inner connector so as to enhance the endurance strength for better locking of the fastening handle, and the fastening handle can be released after locking so as to achieve an anti-open effect.

Description

Quick release screw structure

The invention is a quick-disconnecting screw structure, which enables the quick-release screw to increase the endurance strength and can better lock the effect, and the shank of the locking can be detached, thereby obtaining the anti-theft function.

Check, the quick-disassembling screw structure of the known, as shown in Figure 1 and Figure 2, is a screw 10 with a screw at both ends, a nut 11 at one end, a forced sleeve 12 at the other end, a positioning block 13, a lock The forced handle 15, the combination structure of the locking handle 15 and the screw 10 is configured such that the locking handle 15 has an eccentric hole 16 and a pivot joint 14 is assembled, the pivot joint 14 is combined with the screw 10, and the locking lock is forced to the handle 15 at different angles (eg As shown in FIG. 2, the screw 10 can be actuated by the eccentric hole 16 to achieve the purpose of locking and relaxing. The above structure has the following disadvantages: (1) the locking handle 15 is directly coupled to the pivot joint 14 The locking handle 15 is made of aluminum and has low endurance strength. (2) The lock handle 15 is directly connected to the pivot joint 14, and the user cannot repeatedly disassemble and assemble the group. In other words, the thief can operate the lock handle 15 to disassemble and steal. Therefore, the conventional structure has no anti-theft effect.

The invention is to improve the above-mentioned shortcomings. The main technology and purpose are: a connection structure of a locking handle and a screw, and a connecting joint with a pivot joint and an inner joint, a pivot joint for assembling a screw, and an inner joint for assembling The locking handle is used to increase the endurance strength by the connecting head and the inner joint, and the locking joint is combined with the inner joint, so that the user can repeatedly disassemble and lock the handle to achieve the anti-theft function.

Please refer to FIG. 3, FIG. 4 and FIG. 5, which are provided with a nut 21 at one end of the screw 20, a forced sleeve 22, a positioning block 23, a locking handle 38 at the other end, and a combination structure of the locking handle 38 and the screw 20. The connecting head 30 has an eccentric hole 31, a combined hole 32, and a screw hole 33. The eccentric hole 31 is provided with a pivot joint 24, the pivot joint 24 is combined with the screw 20, the combined hole 32 is provided with an inner joint 34, and the inner joint 34 has a screw hole. 35 is provided for the combination lock lever 38, and the locking pin 37 is locked into the screw hole 33 of the connector 30, and the locking pin 37 is locked to the inner joint 34, and the inner joint 34 is formed in the connector 30; The grip portion 39 can be formed in a flat shape.

With the above structure, the following effects and advantages can be formed:

(1) As shown in FIG. 4 and FIG. 5, the rotation locks the upper and lower angles of the handle 38, and the joint 30 can be rotated to pull the screw 20, that is, the lock can be tightened and relaxed. The locking handle 38 of the present invention is combined with the inner joint 34, and the inner joint 34 can be made of steel (non-aluminum) material, so as to have the effect of increasing the endurance strength, so that the locking force can be more powerful, and the inner joint 34 can be more powerful. Strong locks are tight.

(2) As shown in FIG. 5, the locking handle 38 is arranged to be screwed with the screw hole 35 of the inner joint 34, so that the user can detach and combine the same, in other words, the user can detach the locking handle 38, that is, It can prevent others from relaxing the screw 20 to steal and achieve the anti-theft effect.

(3) The grip portion 39 of the lock lever 38 is provided in a flat shape for easy finger grip and force application when the angle is rotated.

In addition, according to the above technical means, the present invention can also be implemented in the following types: as shown in FIG. 6 and FIG. 7, the combination hole 32 of the connector 30 is provided with an internal thread, and the internal joint 34 is provided with an external thread 340. The inner joint 34 is directly screwed into the combined hole 32 of the joint 30, and the inner joint 34 can be positioned for the joint 30.

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.
