Description

Technical Field

[0001] The utility model relates to the technical field of lock buckles, in particular to a double-safety anti-vibration quick-release lock. Background Art

[0002] Many factory equipment are equipped with covers, observation windows and other structures that need to be opened and closed frequently, so as to check the operating status of the machine at any time. In order to facilitate the opening and closing of covers and other structures, the structure and the corresponding base locking connection gradually use quick release locks to replace the threaded connection structure. The quick release lock is a quick-install and quick-disassemble structure with quick opening and closing, which is mostly used in the aerospace field. The quick release lock is not only simple to operate, safe and reliable, and easy to disassemble and assemble, but also can greatly improve production efficiency.

[0003] In the prior art, quick-release locks for vibration resistance and installation safety mostly use a structure in which a spring and a retaining ring cooperate. The authorization announcement number is CN205895850U, and the patent name is a vibration-proof quick-release lock structure. In the quick-release lock mechanism, the support leg of the slider extends into a strip groove on the lock seat, a spring is provided below the slider, and a push rod is provided above the slider. When using a screwdriver to tighten or loosen the screw, the screwdriver will push the push rod to separate the limit end of the slider from the through hole of the screw, so that the screw can rotate relative to the lock seat to achieve the purpose of tightening or loosening.

[0004] From the above, it can be seen that the length of the spring piece of this type of vibration-resistant quick-release lock structure cannot be too short, and many factory equipment covers, observation windows and other structures are difficult to install, and the structure of the threaded connection between the lock pin and the lock seat cannot achieve the function of quick disassembly and assembly.
