Detailed Description
The present invention will be further described with reference to the accompanying drawings. The following examples are only for illustrating the technical solutions of the present invention more clearly, and the protection scope of the present invention is not limited thereby.
As shown in fig. 1 to 8: the embodiment discloses a push type fluid connector, including male plug 12 and female plug, the lateral part of male plug 12 is equipped with annular 121, and the female plug includes female plug shell 1 and case 2, and the tip of female plug shell 1 is equipped with male plug connecting hole 101, and case 2 is equipped with male plug blind hole 21 and sets up in the snap ring 22 of male plug blind hole 21 internal surface, but case 2 radial telescopic connection in female plug shell 1. Since the male plug 12 and the female plug are connected or disconnected in the axial direction of the two plugs, the radial expansion means perpendicular to the connection direction of the female plug.
When the male plug 12 is connected to the female plug, the male plug 12 passes through the male plug connecting hole 101, the male plug locking hole 21, and the snap ring 22 is connected to the ring groove 121. The external force of the snap ring 22 connected to the ring groove 121 is a spool spring 3, and the spool spring 3 is disposed between the housing 1 and the spool 2 to elastically move the snap ring 22 toward the ring groove 121.
In order to prevent the spool spring 3 from being separated from the spool 2, the spool 2 is connected to the spool spring 3 through the positioning groove 23.
The radial dimension of the snap ring 22 relative to the male plug locking hole 21 is reduced from the valve core spring connection position of the valve core 2 to the pressing side of the valve core in sequence, referring to fig. 5, D1 in fig. 5 is larger than D2, and D2 is larger than D3, so that the advantage that when the valve core 2 is pressed, the inner edge of the snap ring 22 can be clamped or separated with the annular groove 121 at the same time, and the clamping strength and the operation convenience of the two are ensured.
In order to facilitate the convenience of connecting the male plug 12 with the female plug, the male plug connecting side of the snap ring 22 of the embodiment is further provided with a wedge surface 221 used for being matched with the end of the male plug 12, so that when the male plug 12 is plugged into the female plug, the valve core 2 can be extruded through the matching of the end of the male plug 12 and the wedge surface 221, the male plug 12 enters the male plug locking hole 21, and the valve core 2 does not need to be pressed.
The embodiment further comprises a female plug connector 10, a valve core sleeve 4, a valve rod seat 9 and a valve rod seat spring 11, the female plug connector 10 is connected to the female plug shell 1 through threads, one end of the valve rod seat spring 11 is connected to the female plug connector 10, the other end of the valve rod seat spring is connected to the valve core sleeve 4 through the valve rod seat 9, and the valve rod seat 9 is further provided with a valve rod head 7 for connecting a male plug 12. The other end of the female plug connector 10 is also typically provided with an internally threaded bore 13 for enabling connection to other equipment.
Sealing rings are arranged between the valve core sleeve 4 and the female plug connector 10, between the valve rod seat 9 and the valve core sleeve 4 and in the inner hole of the valve core sleeve 4, wherein a second sealing ring 6 is arranged between the valve core sleeve 4 and the female plug connector 10, a third sealing ring 8 is arranged between the valve rod seat 9 and the valve core sleeve 4, and a first sealing ring 5 is arranged in the inner hole of the valve core sleeve 4, so that the sealing between the male plug 12 and the female plug is realized by the sealing rings.
Because under the effect of the spool spring 3, the snap ring 22 extends into the annular groove 121, in order to avoid the separation between the spool 2 and the female plug housing 1, a limit position needs to be set between the spool 2 and the female plug housing, in this embodiment, when the male plug 12 is not connected to the female plug, the limit position is realized by a mode that the spool sleeve 4 extends into the male plug locking hole 21. Obviously, when the male plug 12 is connected to the female plug, the male plug 12 pushes the valve core sleeve 4 to be separated from the male plug locking hole 21 and to be inserted into the male plug locking hole 21, and the position limitation of the valve core 2 is realized through the male plug 12.
As shown in fig. 8: the stem seat 9 of the present embodiment is connected to the stem seat spring 11 by a plurality of radial extensions 92, and the gaps between these radial extensions 92 are sufficient for the passage of fluid. Likewise, the stem seat 9 is connected to the end of the male plug 12 by lateral extensions 91.
During the use, when the connector is connected to needs, insert public plug 12 to public plug connecting hole 101, public plug dead lock hole 21 in proper order, then press down case 2 and can continue to insert public plug 12, stretch into the inside to annular 121 until snap ring 22, realize being connected of public plug 12 and female plug. The fluid connector after connection can realize sealing under the action of a plurality of sealing rings. In the above connection process, due to the wedge surface 221, the movement of the valve core 2 can be realized by pushing the male plug 12 with force, without pressing the valve core 2. When the connector needs to be separated, the male plug 12 can be ejected under the action of the valve rod seat spring 11 by only pressing the valve core 2 to separate the snap ring 22 from the annular groove 121.
The utility model discloses a mode that case spring 3 driven valve core 2 along 1 radial movement of female plug shell realizes being connected and sealed of public plug 12 and female plug, because the steel ball cover that the steel ball locking mode needs the axial displacement outside when inserting or extracting the plug among the prior art, consequently operates more loaded down with trivial details, and the utility model discloses only need radially press case 2 can realize the connection or the separation of connector, on the other hand, only need promote public plug 12 hard when making public plug 12 insert to the female plug because the existence of wedge 221, and need not press case 2 and can realize connecting, also be like this among the prior art advantage that steel ball formula locking does not possess.
The above is only a preferred embodiment of the present invention, and it should be noted that, for those skilled in the art, a plurality of modifications and variations can be made without departing from the technical principle of the present invention, and these modifications and variations should also be regarded as the protection scope of the present invention.
