Problems solved by technology
[0002] At present, the traditional bolt technology is to screw the screw into the threaded sleeve step by step. Although this common bolt technology can ensure good tensile strength, its installation process is relatively complicated; in the case of quick-insert bolts In technology, although the screw can be quickly inserted into the bolt, after tightening, the thread on the screw and the thread on the screw sleeve only partially cooperate, and its tensile strength is weaker than that of ordinary bolts

[0068] Specific implementation: When the bolt is not in use, when the ring thread 10 area of the stud ring 3 radian π / 2 is matched with the non-threaded area of the screw sleeve 2 radian π / 2, the stud ring 3 can be quickly inserted into the screw sleeve 2 The top block 16 is in contact with the smallest radial diameter of the cam 6, the second limit block 18 is in contact with one of the two first limit blocks 13, and the first slider 17 does not extend out of the first slider hole 20.
[0069] When the bolt is in use, the staff can fix the first six head 1, and then make the bolt in a tightened state by twisting the second six head 5. When the staff just started screwing the second six head 5, the stud ring 3 did not rotate, and now the second six head 5 could drive the cam 6 to rotate through the adjusting rod 4, and the rotation of the cam 6 could make the first slider 17 Stretch out the first slider hole 20; in this process, the second limit block 18 rotates with the ...

The invention belongs to the technical field of bolts, and particularly relates to a quick fit bolt. The quick fit bolt comprises a first six-head thread insert, a stud ring, an adjusting rod, a ringthread, a top block, a volute spiral spring, a second C-type spring, a shifting block guide groove and the like. When the ring thread area of the radian pi / 2 of the stud ring is matched with the non-thread area of the radian pi / 2 of the thread insert, the stud ring can be rapidly inserted into the thread insert, then the stud ring is rotated within the 90-degree range, and thus the bolt can be quickly mounted; and at the same time, when the stud ring rotates, the strength of extension between the stud ring and the thread insert is increased through sliding extending out of a first sliding block and a second sliding block. The quick fit bolt is simple in structure and has a better practical effect.
Description
technical field [0001] The invention belongs to the technical field of bolts, in particular to a fast fitting bolt. Background technique [0002] At present, the traditional bolt technology is to screw the screw into the screw sleeve step by step through the thread fit method. Although this common bolt technology can ensure good tensile strength, its installation process is relatively complicated; in the quick-insert bolt In technology, although the screw can be quickly inserted into the bolt, after tightening, the thread on the screw and the thread on the screw sleeve only partially cooperate, and its tensile strength is weaker than that of ordinary bolts. In order to make the quick-insert bolt retain its convenient installation characteristics and have better tensile strength, it is necessary to design a quick-fit bolt with better tensile strength. [0003] The present invention designs a quick fitting bolt to solve the above problems. Contents of the invention [0004...
