Specific embodiment
The following will be combined with the drawings in the embodiments of the present invention, carries out the technical scheme in the embodiment of the utility model
Clearly and completely describe, it is clear that the described embodiments are only a part of the embodiments of the utility model, rather than whole
Embodiment.Based on the embodiments of the present invention, those of ordinary skill in the art are without making creative work
Every other embodiment obtained, fall within the protection scope of the utility model.
Fig. 1-4 is please referred to, a kind of embodiment provided by the utility model: a kind of quick coupling with self-locking function, packet
Pin end 1 and female connector 9 are included, the middle position of pin end 1 is equipped with the second through-hole 17, and pin end 1 includes inserting groove 12 and limit
The middle position in position portion 18,18 side of limiting section is equipped with plug division 16, and the outside of limiting section 18 is welded with ring limit block
2, the side of pin end 1 is equipped with female connector 9, and the side of female connector 9 is equipped with docking section 8, the radius and limiting section 18 of docking section 8
Radius it is equal, 8 two sides of docking section are all welded with hinged seat 5, and the top of hinged seat 5 is hinged with pressing lever 3 by articulated shaft, presses
One end of compression bar 3 is equipped with hook 19, and the both ends of articulated shaft are all equipped with torsional spring 6,8 sidewall weld of docking section of 5 side of hinged seat
There is U-typed bar 7, and U-typed bar 7 is located at the outside of pressing lever 3, the inside of docking section 8 is equipped with annular groove 4, and annular groove 4
Inside be equipped with ring slider 14, between the side and annular groove 4 of ring slider 14 equidistantly be equipped with multiple reset springs 13,
The other side of ring slider 14 is welded with extrusion cylinder 15, and one end of extrusion cylinder 15 extends to the side of docking section 8, annular groove
It is equipped with inserting groove 12 inside the docking section 8 of 4 insides, plug division 16 is mutually matched with inserting groove 12, the side inside inserting groove 12
Equipped with sealing ring 11, and first through hole 10 is equipped with inside the female connector 9 of 12 side of inserting groove.
Working principle: in use, the plug division 16 of pin end 1 to be directed to the inserting groove 12 of docking section 8, due to U-typed bar
7 presence keeps the hook 19 of pressing lever 3 concordant with docking section 8, and the radius of docking section 8 is equal with the radius of limiting section 18,
To keep the hook 19 of pressing lever 3 concordant with 18 outside of limiting section, pin end 1 is at this moment pushed, the plug division 16 of pin end 1 is inserted
Enter in the inserting groove 12 of docking section 8, the hook 19 of pressing lever 3 can be made to move on the outside of limiting section 18, when the limiting section of pin end 1
18 with extrusion cylinder 15 contact when, continue to move to pin end 1, at this moment limiting section 18, which can squeeze extrusion cylinder 15, makes the annular of extrusion cylinder 15
14 compression reseting spring 13 of sliding block and to moving inside annular groove 4, when extrusion cylinder 15 is completely into 4 inside of annular groove,
