Description
Technical field
The utility model relates to quick couplings.
Background technique
The connection of pipe fitting and connector is mostly used in the prior art is spirally connected by connector, installation complexity and stability
It is not high, often there is leakage even pipe fitting obscission to generate；Also occur small part quick coupling, but such fast quick access on the market
Head shows still not ideal enough in stability, durability, and slightly external force there may be leakage or makes pipe fitting fall off.
Utility model content
The utility model aim is to overcome above-mentioned the deficiencies in the prior art, provides a kind of reliable quick coupling.
The technical solution of the utility model is: a kind of quick coupling, including adapter body and is connected to the connector master
Cutting ferrule on the socket of body, is equipped with a bulge loop on the inside of the socket, the bulge loop towards the side of socket be slope, it is described to connect
The main intracorporal middle part of head is additionally provided with a stop collar, and sealing ring, the bulge loop and sealing ring are equipped between the bulge loop and stop collar
Between adapter body on the inside of also there is a tapered channel, the sealing ring be positioned at the tapered channel inner end and stop collar it
Between, the front end of the cutting ferrule has the first limiting section, is additionally provided with latch, the middle part of the cutting ferrule on the inside of first limiting section
With two limiting sections, the rear end of the cutting ferrule has cutting ferrule seat, and the cutting ferrule, which is inserted into the socket, makes the bulge loop be caught in first
Between limiting section and the second limiting section, the cutting ferrule seat and the socket periphery are additionally provided with mutual corresponding recess, the recess
On be equipped with spring.
Further, the cutting ferrule is stainless steel cutting ferrule, corrosion-resistant, sturdy and durable.
Further, the sealing ring is viton seal ring, good corrosion resistance.
Further, the adapter body both ends are designed with socket, and there are two the cutting ferrules.
The beneficial effects of the utility model are: the utility model stable connection is reliable, efficient and convenient, sturdy and durable.
Detailed description of the invention
Fig. 1 is the structural schematic diagram of the utility model.
Specific embodiment
Below with reference to the embodiments and with reference to the accompanying drawing the technical solutions of the present invention will be further described.
As shown in Figure 1, a kind of quick coupling, including adapter body 1 and is connected on the socket of the adapter body 1
Cutting ferrule 2, is equipped with a bulge loop 3 on the inside of the socket, the bulge loop 3 towards the side of socket be slope 4, the adapter body 1
Interior middle part is additionally provided with a stop collar 5, and sealing ring 6, the bulge loop 3 and sealing ring 6 are equipped between the bulge loop 3 and stop collar 5
Between the inside of adapter body 1 also there is a tapered channel 7, the sealing ring 6 is positioned at 7 inner end of tapered channel and limit
Between ring 5, the front end of the cutting ferrule 2 has the first limiting section 8, and the inside of first limiting section 8 is additionally provided with latch 9, described
The middle part of cutting ferrule 2 has two limiting sections 10, and the rear end of the cutting ferrule 2 has cutting ferrule seat 11, and the cutting ferrule 2, which is inserted into the socket, to be made
The bulge loop 3 is caught between the first limiting section 8 and the second limiting section 10, and the cutting ferrule seat 11 and the socket periphery are additionally provided with phase
Mutual corresponding recess is equipped with spring 12 in the recess.
Further, the cutting ferrule 2 is stainless steel cutting ferrule.
Further, the sealing ring 6 is viton seal ring.
Further, 1 both ends of adapter body are designed with socket, and there are two the cutting ferrules 2.
When the utility model is used, pipe fitting is inserted into cutting ferrule, cutting ferrule is inserted into interface, when the first limiting section passes through bulge loop
When, latch locking pipe fitting on the inside of the first limiting section is simultaneously connected on tapered channel, completes the connection of pipe fitting and adapter body.
Due to being provided with spring in the recess of cutting ferrule seat and socket, spring can tense cutting ferrule outward automatically when in use, make
The stronger latching pipe fitting of latch, increases stability when card pipe, simultaneously because the setting of spring, at the lock tube of pipe fitting extremely
The distance of nozzle also needs accordingly to extend, and when accident occur or having extraneous factor influence, pipe fitting also has more space lengths
It goes to continue steady operation, unnecessary loss can be reduced.
It should be noted that it can directly on the other element when element is referred to as " being fixed on " another element
Or there may also be elements placed in the middle.When an element is considered as " connection " another element, it, which can be, is directly connected to
To another element or it may be simultaneously present centering elements.Term as used herein " vertical ", " horizontal ", " left side ",
" right side " and similar statement for illustrative purposes only, are not meant to be the only embodiment.
Unless otherwise defined, all technical and scientific terms used herein are led with the technology for belonging to the utility model
The normally understood meaning of the technical staff in domain is identical.Terminology used in the description of the utility model herein only be
The purpose of description specific embodiment, it is not intended that in limitation the utility model.Term " and or " used herein packet
Include any and all combinations of one or more related listed items.
The above is only the preferred embodiment of the utility model only, is not intended to limit the utility model, all at this
Within the spirit and principle of utility model, any modification, equivalent replacement, improvement and so on should be included in the utility model
Protection scope within.
