[0041] To make the technical problems solved, the technical solutions, and the beneficial effects of this invention clearer, the invention will be further described in detail below with reference to the accompanying drawings and embodiments. It should be understood that the specific embodiments described herein are merely illustrative of the invention and are not intended to limit the invention.
[0042] In the description of this invention, it should be understood that the terms "longitudinal," "radial," "length," "width," "thickness," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships, are based on the orientation or positional relationships shown in the accompanying drawings and are only for the convenience of describing the invention and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of the invention. In the description of this invention, unless otherwise stated, "a plurality of" means two or more.
[0043] In the description of this invention, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal encapsulation of two components. Those skilled in the art can understand the specific meaning of the above terms in this invention based on the specific circumstances.
[0044] The following is in conjunction with the appendix Figure 1-2 This invention describes a multi-port air fitting according to an embodiment of the present invention.
[0045] like Figure 1 As shown, the multi-port vent connector of this utility model includes a female connector 1 and a male connector 2 that are plug-in mated and detachably connected by a snap-fit connector.
[0046] like Figure 2 As shown, the female head 1 has a plurality of first fluid channels 101 extending through it, and the plurality of first fluid channels 101 are spaced apart along a first direction;
[0047] like Figure 2 As shown, the male connector 2 has a plurality of insertion portions 202 that are respectively adapted to be inserted into a plurality of first fluid channels 101, and each insertion portion 202 is provided with a second fluid channel 201 that penetrates the male connector 2;
[0048] like Figure 2 As shown, a stepped portion 6 is provided on the inner wall of the first fluid channel 101, and a sound-absorbing plate 3 is provided between the insertion portion 202 and the stepped portion 6.
[0049] In other words, the side of the silencing plate 3 near the step 6 abuts against the step 6, and the side of the silencing plate 3 near the plug abuts against the plug portion 202.
[0050] Specifically, the sound-absorbing sheet 3 is a porous sheet formed by sintering PE material. That is, the sound-absorbing sheet 3 has a porous structure. The porous structure of the sound-absorbing sheet 3 can reduce the gas flow rate while maintaining the connection between the first fluid channel 101 and the second fluid channel 201, thereby achieving the effect of reducing gas noise.
[0051] Therefore, the multi-channel air pipe structure of this utility model embodiment can reduce the flow rate of gas from the first fluid channel 101 to the second fluid channel 201 by setting a sound-absorbing plate 3 between the male head 2 and the female head 1, thereby reducing the noise generated by gas flow.
[0052] Therefore, the multi-port air pipe connector of this utility model embodiment has the characteristic of low noise.
[0053] In some embodiments, such as Figure 2As shown, the female connector 1 has two first fluid channels 101, and correspondingly, the male connector 2 has two insertion parts 202. The two insertion parts 202 of the male connector 2 are respectively inserted into and fitted into the two first fluid channels 101.
[0054] In some embodiments, the multi-port vent connector of this utility model further includes a rubber gasket 4. The rubber gasket 4 is disposed between the silencing plate 3 and the insertion part 202. The rubber gasket 4 has a through hole corresponding to the second fluid channel 201 of the insertion part 202 to connect the first fluid channel 101 and the second fluid channel 201, so that the gas in the second fluid channel 201 of the male connector 2 can enter the first fluid channel 101 of the female connector 1 through the through hole of the rubber gasket 4. At the same time, the rubber gasket 4 is a flexible material, which can absorb the pressure applied to the silencing plate 3 after the insertion part 202 of the male connector 2 is installed in the first fluid channel 101 of the female connector 1.
[0055] In some embodiments, a sealing ring 5 is provided between the plug portion 202 and the female head 1.
[0056] Furthermore, an annular groove 7 is provided on the outer peripheral wall of the insertion part 202 or on the inner peripheral wall of the first fluid channel 101 of the female head 1, and the sealing ring 5 is disposed in the annular groove 7.
[0057] In other words, an annular groove 7 can be provided on the outer peripheral wall of the insertion part 202 for installing the sealing ring 5, and an annular groove 7 can also be provided on the inner peripheral wall of the part corresponding to the insertion part 202 in the first fluid channel 101 for installing the sealing ring 5.
[0058] It is understood that by setting a sealing ring 5 between the male connector 2 and the female connector 1, the sealing performance between the male connector 2 and the female connector 1 can be greatly improved, thereby greatly improving the sealing performance of the multi-port vent connector of this utility model embodiment.
[0059] In some embodiments, such as Figure 2 As shown, the male head 2 has extensions 8 extending in a second direction at both ends opposite to each other in the first direction, and the second direction is perpendicular to the first direction.
[0060] The extension 8 is provided with a first limiting protrusion 9, and the female head 1 is provided with a second limiting protrusion 10 corresponding to the first limiting protrusion 9 and cooperating with the first limiting protrusion 9.
[0061] The multi-port vent connector of this utility model is provided with a first limiting protrusion 9 and a second limiting protrusion 10 that can be engaged with each other, so that the male head 2 and the female head 1 are detachable. When the first limiting protrusion 9 and the second limiting protrusion 10 are engaged with each other, the male head 2 and the female head 1 are in a connected and fixed state. When the first limiting protrusion 9 and the second limiting protrusion 10 are disengaged from each other, the male head 2 and the female head 1 are in a separated state.
[0062] Therefore, it is convenient for staff to install and disassemble the male connector 2 and the female connector 1, and thus facilitates the installation and disassembly of the multi-port vent connector of this utility model embodiment, greatly improving the ease of installation and disassembly of the multi-port vent connector of this utility model embodiment.
[0063] As mentioned above, a flexible rubber ring gasket 4 is provided between the silencing plate 3 and the insertion part 202. When the insertion part 202 of the male connector 2 is inserted into the first fluid channel 101 of the female connector 1 and the limiting protrusion is engaged in the limiting groove, the insertion part 202 squeezes the rubber ring gasket 4. On the one hand, the rubber ring gasket 4 can absorb part of the force exerted by the insertion part 202 on the silencing plate 3 through deformation. On the other hand, the deformed rubber ring gasket 4 can exert a reaction force on the insertion part 202, thereby making the first limiting protrusion 9 of the male connector 2 and the second limiting protrusion 10 of the female connector 1 fit more tightly, thereby greatly improving the connection stability between the female connectors 1 and the female connector 1.
[0064] In some embodiments, the female head 1 has two baffles 11 spaced apart in the thickness direction on both sides in the first direction; a guide groove 12 is defined between the two baffles 11, a second limiting protrusion 10 is provided in the guide groove 12, and the extension 8 is slidably fitted in the guide groove 12. The thickness direction of the female head 1 is perpendicular to both the first direction and the second direction, and the first direction, the second direction and the thickness direction of the female head 1 are perpendicular to each other.
[0065] The multi-port vent connector of this utility model uses two baffles 11 to define a guide groove 12 on the female connector 1 that can slide with the extension 8. When the insertion part 202 is inserted into the first fluid channel 101 of the female connector 1, the extension 8 is slidably fitted into the guide groove 12. The guide groove 12 can guide the extension 8 to move in the second direction, and correspondingly guide the first limiting protrusion 9 to move to the first limiting protrusion 9 and engage with the first limiting protrusion 9 for locking, thereby fixing the male connector 2 and the female connector 1 together.
[0066] When it is necessary to disassemble the male connector 2 and the female connector 1, simply move the extension part 8 to disengage the first limiting protrusion 9 from the second limiting protrusion 10 to achieve the effect of disassembling the male connector 2 and the female connector 1.
[0067] In some embodiments, the end of the extension 8 that is away from the body extends beyond the end face of the female head 1 that is away from the male head 2 in a first direction.
[0068] Furthermore, the female head 1 has a first connector 13 on the end face away from the male head 2 in the first direction, which is connected to the first fluid channel 101, and the outer periphery of the first connector 13 has a first annular protrusion 131.
[0069] Furthermore, the male head 2 has a second connector 14 connected to the second fluid channel 201 on the end face away from the female head 1 in the first direction, and the outer periphery of the second connector 14 has a second annular protrusion 141.
[0070] The multi-port air hose connector of this utility model embodiment, by providing a first connector 13 and a second connector 14, facilitates the connection of the air hose to the male connector 2 and the air hose to the female connector 1. At the same time, the first annular protrusion 131 and the second annular protrusion 141 respectively provided on the first connector 13 and the second connector 14 can improve the friction between the air hose and the first connector 13 and the second connector 14, thereby enabling the air hose to be connected more stably to the first connector 13 and the second connector 14.
[0071] The above-described embodiments are only used to illustrate the technical solutions of the present invention, and are not intended to limit it. Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features. Such modifications or substitutions do not cause the essence of the corresponding technical solutions to deviate from the spirit and scope of the technical solutions of the embodiments of the present invention, and should all be included within the protection scope of the present invention.
