Flip machine box, non-tool operation type locking device thereof and lock

Abstract

The invention relates to the field of rapid dismounting and locking devices, in particular to a flip machine box, a non-tool operation type locking device thereof and a lock. The non-tool operation type locking device comprises the lock and a locking dog. The lock comprises a fixing sleeve extending in the forward and backward directions. The front end of the fixing sleeve is provided with a mounting structure which forms a mounting base of the lock. The fixing sleeve is provided with a locking hole. The front end of the locking hole is provided with a locking dog inserting opening allowing the locking dog to be inserted. The hole wall of the locking hole is provided with a ball mounting hole penetrating through the side wall of the fixing sleeve. A ball is assembled into the ball mounting hole in a guiding mode. The diameter of the ball is larger than the length of the ball mounting hole. The locking dog is provided with a locking groove used for being in locking fit with the ball. The periphery of the fixing sleeve is sleeved with a mobile sleeve. The fixing sleeve is provided with an elastic locking component used for providing forward acting force for the mobile sleeve. The mobile sleeve is mounted on the fixing sleeve in an abutting mode through the elastic locking component and provided with an abut-pushing wall face and a receding structure. By adoption of the flip machine box, the non-tool operation type locking device thereof and the lock, the problems that existing locking devices are inconvenient to use and unreliable in locking are solved.

Description

technical field [0001] The invention relates to the field of quick-release locking devices, in particular to a clamshell case, a tool-free operating locking device and a lock body thereof. Background technique [0002] At present, the quick release and quick lock locking methods that can be realized without tools mainly include screw locking, sliding locking, etc. Among them, the captive screw is also called the spring screw, which relies on the pressing spring to control the elongation and shortening of the thread, and relies on the thread to control the locking. However, this method is manually tightened, and it is not easy to control whether it is tightened, and it is inconvenient to use. In addition, this locking method lacks anti-loosening measures and is not resistant to vibration. When it is used in a small space, the spring stroke is small, and sometimes it is difficult to judge whether the thread is pressed out during operation, and the locking is unreliable. [00...
