Make personnel and judge whether locking in place by hitting the sound generated, avoids generation locking not in place, promote reliability.
Further, in this embodiment being equipped with the locking slot 51 for being used to cooperate with tight lock part 12 to locking member 5.Work as lock
When tight portion 12 rotates into locking slot 51 with lock core 1, it can be realized and reliably lock, avoid the two from being mutually disengaged, improve
The reliability of locking.Wherein the item number of locking slot 51 and position can be adjusted according to shape, the size to locking member 5；When
So in other embodiments, protrusion can also be arranged in locking member 5 to compress for the portion 12 that is locked.
As a preferred technical solution, in the present embodiment, the two sides of tight lock part 12 are equipped with for guiding tight lock part 12 to enter
Guiding surface 121 in locking slot 51.Two guiding surfaces 121 screw in locking slot 51 forward or backwards convenient for tight lock part 12.
Fig. 3 shows above-mentioned for locking the implementation of the locking method of the quick-locking mechanism to locking member and fixing piece
Example, the locking method for being used to lock the quick-locking mechanism to locking member and fixing piece of the present embodiment, comprising the following steps:
S1, when judging lock core 1 far from fixing piece 8, tight lock part 12 and to which whether between locking member 5 interference can be generated, if not
Then directly execute step S2；If then rotary locking cylinder 1 is up to tight lock part 12 and to no longer generate interference between locking member 5, then
Execute step S2；
S2, to mobile lock core 1 in side (in attached drawing be right side) far from fixing piece 8 until tight lock part 12 is located to locking member
5 sides far from fixing piece 8, namely to locking member 5 between fixing piece 8 and tight lock part 12；
S3, rotary locking cylinder 1 until when lock core 1 is close to fixing piece 8 tight lock part 12 with to locking member 5 can generate interference, namely
Tight lock part 12 can be by the side compression to locking member 5 to 8 place of fixing piece under the action of resilient latching member 2；
S4, compress tight lock part 12 to locking member 5, specially locking slot 51 to close to the mobile lock core 1 in the side of fixing piece 8
Side wall close to 8 side of fixing piece.
This is used to lock the locking method of the quick-locking mechanism to locking member and fixing piece, it is only necessary to pass through the movement of lock core
Locking can be realized with rotation, unlock can be realized by reversely rotating, tightened compared to using threaded fastener, lock and unlock
It is more convenient, quick, especially it is not easy to the environment using fastener locking
Although the present invention has been disclosed as a preferred embodiment, however, it is not intended to limit the invention.It is any to be familiar with ability
The technical staff in domain, without deviating from the scope of the technical scheme of the present invention, all using the technology contents pair of the disclosure above
Technical solution of the present invention makes many possible changes and modifications or equivalent example modified to equivalent change.Therefore, all
Without departing from the content of technical solution of the present invention, according to the present invention technical spirit any simple modification made to the above embodiment,
Equivalent variations and modification, all shall fall within the protection scope of the technical scheme of the invention.
