Description
Technical field
The utility model relates to a kind of quick couplings.
Background technique
Quick coupling is that a kind of tool that do not need can be achieved with the connector of pipeline connection or disconnection.Quick coupling can be divided into:
It is air snap joint, oxygen fuel gas snap joint, gas-liquid sharing snap joint, oil pressure snap joint, lazy
The quick coupling of property gas, the quick coupling of coolant water temperature oil, semiconductor snap joint.
A kind of existing quick coupling structure is equipped with valve in 1 ' of joint housing as shown in Figure 1, including 1 ' of joint housing
One gasket, 3 ' is installed below 2 ' of spool inside 2 ' of core, 1 ' of joint housing, 4 ' of spring, pad are equipped between 3 ' of 2 ' of spool and gasket
3 ' of piece is fixed on the inside of 1 ' of joint housing by 5 ' of internal jump ring, since 3 ' of gasket is equipped with 3 stabilizer blades, usually in use, pad
3 ' of piece is easy to fall off from 5 ' of internal jump ring, to make 2 ' of spool fail, and 1 ' of joint housing is integral structure, it has not been convenient to
The installation of 3 ' of gasket.
Summary of the invention
In order to solve the above-mentioned technical problem, the utility model provides a kind of safe and reliable, long service life, easy for installation
Quick coupling.
The technical solution adopted in the utility model is:
A kind of quick coupling, including joint housing, spool, gasket, the spool and gasket are installed in joint housing, institute
It states and spring is installed between spool and gasket, it is characterised in that: the joint housing is to be connected to be formed with pedestal by plug, described
Base inner wall is equipped with the step of the protrusion setting for setting-up piece.The utility model joint housing is arranged to it is split type,
The step of setting setting-up piece, facilitates gasket to be installed in joint housing in pedestal, and gasket positioning is firm, not easily to fall off.
Further, the plug is to be threadedly coupled with pedestal.
Further, the lower part of the plug is provided with external screw thread, and correspondingly, the inner wall of the pedestal is equipped with internal screw thread.
Further, the first O-ring of sealing is equipped between the pedestal and plug.
Further, first O-ring is set to the end of pedestal Yu plug connecting pin.
Further, the second O-ring of sealing is equipped between the spool and plug.
Further, the valve core outer surface is provided with the annular groove of the second O-ring of installation.
Further, outer circlip is installed outside the pedestal.
It is suitable for pin end and female connector at the improvement of quick coupling described in the utility model.
The beneficial effects of the utility model are: facilitating the installation of gasket, gasket positioning is firm, not easily to fall off.

Specific embodiment
Combined with specific embodiments below the utility model to be further described, but the utility model is not limited to
In these specific embodiments.One skilled in the art would recognize that the utility model covers in Claims scope
All alternatives, improvement project and the equivalent scheme that may include.
Referring to fig. 2-4, a kind of quick coupling, including joint housing, spool 2, gasket 4, the spool 3 are installed with gasket 4
In in joint housing, being equipped with spring 3 between the spool 3 and gasket 4, the joint housing is connected by plug 1 and pedestal 5
It is formed, 5 inner wall of pedestal is equipped with the step 51 of the protrusion setting for setting-up piece 4.The utility model sets joint housing
It is set to split type, the step of setting-up piece 4 is set in pedestal 5, gasket 4 is facilitated to be installed in joint housing, and gasket 4 is fixed
Position is firm, not easily to fall off.
Plug 1 described in the present embodiment is to be threadedly coupled with pedestal 5, is easy for installation and removal.Specifically, the plug 1
Lower part is provided with external screw thread, and correspondingly, the inner wall of the pedestal 5 is equipped with internal screw thread.It is equipped between the pedestal 5 and plug 1 close
First O-ring 7 of envelope.First O-ring 7 is set to the end of pedestal 5 Yu 1 connecting pin of plug.
Likewise, the inner wall for being also possible to the plug 1 is provided with internal screw thread, correspondingly, the top of the pedestal 5 is equipped with
External screw thread.First O-ring 7 is set to the end of plug 1 Yu 5 connecting pin of pedestal.
The second O-ring 8 of sealing is equipped between spool 2 and plug 1 described in the present embodiment.2 outer surface of spool is set
It is equipped with the annular groove of the second O-ring 8 of installation.
Base outer surface described in the present embodiment is equipped with jump-ring slot at connecting pin, and jump-ring slot is equipped with outer circlip 6.
Gasket 4 described in the present embodiment includes a circular body, and the center of circular body is equipped with the through-hole that spool 2 is worn, circle
The periphery of shape ontology is equipped with 3 positioning stabilizer blades.
When the utility model assembles, first spool 2 is fixed in plug 1, spring 3 is placed on 2 lower part of spool, then by gasket
4 are placed on 2 lower part of spool, are finally fixedly connected with plug 1 with pedestal 5, facilitate the installation of gasket 4, and it is firm that gasket 4 positions, and is not easy
It falls off.The repairing and replacement of the inner bodies such as spool extend the use of quick coupling as long as opening plug 1 and pedestal 5
Service life, save the cost.
