33 gear piece ratchet engagement, with further mutually plugging together for the second fastener 2 and the first fastener 1, the second fastener 2 and the first fastener
1 hook is relative to be engaged, by breastbone close and fixation；The runner 4 on the first fastener 1 is rotated again, and the major axis for making its oval refers to
To the concave arc area 32 of elastic gear piece 3, locking of the runner 4 to elastic strip 33 is realized；Multiple closing points are set along breastbone successively, it is complete
Into breastbone close operation.
The sealed and self-locking of the present invention
Refering to Fig. 1, Fig. 2, Fig. 6, rotating wheel 4 releases limitation of the runner 4 to elastic strip 33；The slide rail 21 of second fastener 2 is inserted
Close in the chute 11 of the first fastener 1, the fastener ratchet 22 of the second fastener 2 is engaged with the gear piece ratchet 34 of elastic strip 33, when the
Slide rail 21 on the plug-in unit 25 of two fasteners 2 is plugged together in the chute 11 of the first fastener 1 to when plugging together direction movement, is plugging together external force
In the presence of, 22 need of fastener ratchet of the second fastener 2 overcome the elastic force of elastic strip 33 and gear piece ratchet edge to plug together direction and enter one
Step engagement；Disappeared when plugging together external force, because the tooth form of ratchet has the effect of one-way check, elastic strip 33 recovers elasticity, gear piece
Ratchet 34 is locked by fastener ratchet 22, and the slide rail 21 of the second fastener 2 can not in reverse direction be moved in the chute 11 of the first fastener 1
It is dynamic, beneficial to the closure in operation to breastbone and fixation；When the position for being moved to breastbone close of the first fastener 1 and the second fastener 2
When putting, rotating wheel 4 realizes locking of the runner 4 to elastic strip 33.
The unblock of the present invention
Refering to Fig. 1, Fig. 2, Fig. 5, in use, no matter which kind of reason, once need to release the first fastener 1 and the second fastener
2 it is sealed when, only need to rotate the runner 4 on the first fastener 1, its oval short axle is pointed to the concave arc area 32 of elastic gear piece 3, solution
Limitation except runner 4 to elastic strip 33；At the tweezers clip 31 that two-side elastic bar 33 is clamped with tweezers, make the elastic both sides of gear piece 3
Elastic strip 33 draw in, the fastener ratchet 22 of the gear piece ratchet 34 on elastic strip 33 and the second fastener 2 is disengaged from, you can by
The slide rail 21 of two fasteners 2 is extracted out out of the first fastener 1 chute 11, completes unblock.
Refering to Fig. 1, Fig. 5, Fig. 6, it is contemplated that the gear piece ratchet 34 of elastic gear piece 3 can be relative to bearing pin when drawing in opening
5 swing, to ensure that the gear piece ratchet at any position on elastic gear piece 3 is effectively engaged with the fastener ratchet of the second fastener 2, the present invention
The nodel line of the gear piece ratchet 34 of elastic strip 33 is designed as camber line.
Refering to Fig. 1, Fig. 5, Fig. 6, because elastic gear piece 3 of the invention is the " u "-shaped piece that both sides are provided with elastic strip, in elastic strip
The inner side of middle part two be provided with concave arc area 32, during work, the elastic strip 33 of the elastic side of gear piece 3 one works as elasticity equivalent to a lever
When gear piece 3 works, gear piece is using pin shaft hole as fulcrum, and the meshing point of gear piece ratchet 34 and fastener ratchet 22 is stress point, is acted on
The runner 4 of concave arc area 32 is application point, when the oval major axis of runner 4 points to the concave arc area 32 of elastic gear piece 3,4 pairs of elasticity of runner
The concave arc area 32 of gear piece 3 exerts a force, and realizes locking of the runner 4 to elastic strip 33；Conversely, when the oval short axle of runner 4 points to elasticity
The concave arc area 32 of gear piece 3, runner 4 discharges the force to the elastic concave arc area 32 of gear piece 3, and runner 4 loses limitation to elastic strip 33.
Refering to Fig. 1, Fig. 6, because the present invention is provided with concave arc area 32 on elastic gear piece 3, when the oval major axis of runner 4 is made
During concave arc area 32 for elastic gear piece 3, i.e., when being exerted a force in the concave arc area 32 of 4 pairs of elastic gear pieces 3 of runner, concave arc area 32 is to runner
4 apply reaction forces, and ensure that the contact condition of runner 4 and the elastic concave arc area 32 of gear piece 3 is stability.
Frictional force when being mutually inserted for the second fastener 2 of raising and the first fastener 1, chute of the present invention in the first fastener 1
11 medial surfaces are provided with ratchet or coarse rubbing surface 13, are provided with ratchet in the lateral surface of slide rail 21 of the second fastener 2 or coarse rub
Wiping face 23.
