Description

Technical Field

[0001] This utility model belongs to the field of connection device technology, specifically relating to a novel shut-off valve used for rapid connection of gas or liquid. Background Technology

[0002] In fields such as beauty equipment, medical devices, and aerospace, quick-connect couplings are often used to achieve rapid connection between liquid or gaseous surfaces. When connecting this type of coupling, the operator pushes the connector and spring in opposite directions with both hands. After the connector is inserted and then released, the spring component compresses the connector, creating axial compression and constraint, thus achieving a rapid connection.

[0003] The current technical problem is that this type of quick connector requires both hands to simultaneously push the springs at both ends of the connector in opposite directions during insertion. This is because the connector ends typically only have an embossed structure to increase friction during axial pushing. Significant hand strength is required for this axial pushing, and the force can only be transmitted through the fingers. Women with less hand strength generally cannot achieve the opening and closing of the connector, and even if they have sufficient hand strength, it can cause finger pain during insertion. This makes it unsuitable for applications such as beauty devices and medical devices where women are the primary operators.

[0004] Given the current situation, as the R&D and design unit of the connector, it is very necessary for the applicant to improve the existing quick-connect connector structure and design a quick-connect connector that is simple in structure, easy to operate, and can be used in the fields of gas and liquid conduction. Summary of the Invention

[0005] To overcome the shortcomings of existing technologies, this utility model provides a novel quick-connect shut-off valve with a simple and novel structural design. It can be connected at both ends through an axial plug-in component, positioned by a radial baffle, and achieve axial conduction through the interaction of internal spring components.

[0006] To achieve the above technical objectives, the present invention adopts the following solution:

[0007] A novel quick-connect shut-off valve includes a female component and a female component. The female component has an axial guide hole inside, a female thread at one end, and a sliding groove and a positioning hole at the other end. A positioning spring and a positioning pin are installed in the positioning hole. A pressing spring is installed on the side wall of the female component.

[0008] The sub-component is axially hollow, with a threaded part on one end and a plug-in section on the other end. The plug-in section is provided with a sealing ring and a positioning groove.

[0009] A positioning plate is inserted into the slide groove. The positioning plate has a through hole for the insertion section to pass through, and a pin hole to cooperate with the positioning pin. The positioning plate is also provided with a pressing plate to cooperate with the pressing spring. The positioning plate moves in the slide groove to achieve insertion and locking with the positioning groove.

[0010] The axial through hole is a stepped hole of the mother part, and a mother part valve core is provided in the stepped hole of the mother part. The mother part valve core is provided with an axial through hole or a side wall hole and a blind hole of the mother part, and the two are connected. A support point is provided on the periphery of the mother part valve core, and a mother part valve core spring is provided between the support point and the stepped hole of the mother part. A mother part sealing ring is provided on the mother part valve core, and an annular protrusion is provided in the stepped hole of the mother part to cooperate with the mother part sealing ring. The mother part valve core spring causes the mother part sealing ring to squeeze the annular protrusion.

[0011] The sub-component has a stepped hole inside, which is used to fix the valve core. The valve core has an axial through hole or a side wall hole and a blind hole, and the two are connected. A sealing ring on the valve core cooperates with the stepped hole at the center of the sub-component to achieve sealing. The valve core has a positioning area that cooperates with the stepped hole to achieve axial unilateral positioning. A spring on the positioning area also constrains the valve core to cooperate with the stepped hole.

[0012] The sub-component is connected to an external connector, and the sub-component spring is disposed between the external connector and the sub-component valve core.

[0013] The mother component is provided with an external connector, which connects to the outside through an external structure.

[0014] The beneficial effects of this utility model are as follows: This utility model includes a female component, a female component, and a positioning plate. The female component has an axial through hole inside, a connecting thread at one end, and a sliding groove and a positioning hole at the other end. A positioning spring and a positioning pin are installed in the positioning hole to fix the positioning plate. A pressing spring is installed on the side wall of the female component. The female component has a stepped hole axially, a connecting thread at one end, and an insertion section at the other end. A sealing ring and a positioning groove are installed on the insertion section. A positioning plate is inserted into the sliding groove to achieve the connection and fixation of the female component and the female component. With the above structural settings, plus the insertion and elastically triggered female and female component valve cores, the visual state of conduction, single-sided cutoff, and double-sided cutoff can be achieved. Its structure is novel and easy to operate, making it an ideal new type of quick-connect stop valve. Attached Figure Description

[0026] The present invention will be described in detail below through specific embodiments. Those skilled in the art can easily understand other advantages and effects of the present invention from the content disclosed in this specification. However, it should be noted that the specific embodiments described below do not limit the technical solution. Those skilled in the art can make further technical extensions under the guidance of the following technical solutions. The scope of protection of this patent application is determined by the claims.

[0027] Example 1:

[0028] A novel quick-connect shut-off valve includes a female component 1 and a female component 3. The female component 1 has an axial through hole inside. In this embodiment, the axial through hole is a circular through hole.

[0029] One end of the female component 1 is provided with a female component thread 11. This female component thread includes external thread or internal thread. The internal thread can be used to connect with the external connector 6, and the external thread can be used to fix it on the equipment by cooperating with the nut 7. The other end of the female component 1 is provided with a sliding groove 12 and a positioning hole 13. The positioning hole 13 is provided with a positioning spring 14 and a positioning pin 15. The side wall of the female component 1 is also provided with a side wall spring hole 16, which is used to fix the side wall spring 17. The side wall spring 17 is used as a pressing spring.

[0030] The sub-component 3 is axially hollow, and one end of the sub-component 3 is provided with a sub-component thread 33. The sub-component thread 33 includes an external thread or an internal thread. The internal thread can be used to connect with an external connector 6, and the external thread can be used to cooperate with a nut 7 to achieve fixation on the equipment. The other end of the sub-component 3 is a plug-in section 30, which is provided with a sealing groove 32 and a positioning groove 34. A sealing ring 35 is provided in the sealing groove 32.

[0031] A positioning plate 2 is inserted into the groove 12 of the female component 1, such as Figure 1 , 3 As shown, the positioning plate 2 is provided with a through hole 24 for the insertion section 30 to pass through. The through hole 24 can be designed as an elliptical hole. The positioning plate 2 is also provided with a pin hole 23 to cooperate with the positioning pin 15. A pressing plate 22 is bent on the positioning plate 2 to cooperate with the pressing spring 17. After the above structure is set, the positioning plate 2 is constrained to the end of the female part 1 by the positioning pin 15 and the sliding groove 12. When the insertion section 30 of the female part 3 is inserted into the female part 1 through the through hole 24, the operator applies force to the pressing plate 22, and the periphery of the pressing plate 22 through the through hole 24 is inserted into the positioning groove 34 to achieve a fixed position. At this time, it can be used for conduction between the female part 1 and the female part 3 without a cut-off function at the axis. This structure is suitable for connection between the female part 1 and the female part 3 under no-pressure conditions at both ends.

[0032] The pin hole 23 on the positioning plate 2, when engaged with the positioning pin 15, can prevent the positioning plate 2 from slipping out of the slide groove 12. When disassembling the positioning plate 2 from the slide groove 12, the positioning pin 15 can be pressed to the bottom of the pin hole 23.

[0033] Example 2: The female component has a high-voltage cutoff function at one end.

[0034] Based on the structure of Embodiment 1, when one end of the mother component 1 serves as a high-pressure water or gas supply end, this device requires that one end of the mother component 1 has a high-pressure shut-off function during use. A specific embodiment is as follows: the axial through-hole on the mother component 1 is a stepped hole 18, and a valve core 5 is installed inside the stepped hole 18. Figure 5 As shown, the female valve core 5 is provided with a female side wall hole 52 and a female blind hole 51, and the two are connected; a support point 53 is provided on the periphery of the female valve core 5, and a female valve core spring 56 is provided between the female valve core spring 56 and the female stepped hole 18; a female sealing groove 54 is provided on the female valve core 5, and a female sealing ring 55 is provided in the female sealing groove 54; an annular protrusion 19 is provided in the female stepped hole 18 to cooperate with the female sealing ring 55; in the non-compression force state, the female valve core spring 56 causes the female sealing ring 55 to compress the annular protrusion 19 to achieve sealing and stop.

[0035] The sub-component 3 has a stepped hole 31 inside, which is used to fix the sub-component valve core 4. The sub-component valve core 4 has an axial through hole, and a sub-component sealing ring 45 is provided on the sub-component valve core 4 to cooperate with the stepped hole 31 at the axis of the sub-component 3 to achieve sealing. The sub-component valve core 4 has a positioning area 44 that cooperates with the stepped hole 31 to achieve axial unilateral positioning. A sub-component spring 36 is also provided on the positioning area 44 to constrain the sub-component valve core 4 to cooperate with the stepped hole 31. In this embodiment, an external connector 6 is connected to the sub-component 3 to fix the end of the sub-component spring 36.

[0036] When the female component 1 and the female component 3 are inserted and combined, the female component valve core 4 and the female component valve core 5 are pressed against each other. After the female component valve core 5 overcomes the elastic force of the female component valve core spring 56 and moves to the right, the annular protrusion 19 is separated from the female component sealing ring 55 and the female component side wall hole 52 and the female component blind hole 51 are in a conductive state. High pressure liquid or high pressure gas can be conducted from the female component 1 side to the female component 3 side.

[0037] Example 3: The daughter component 3 and the mother component 1 both have high voltage cutoff function.

[0038] Based on embodiment 2, the sub-component 3 is provided with a sub-component stepped hole 31 inside, which is used to fix the sub-component valve core 4; the sub-component valve core is provided with a sub-component side wall hole 42 and a sub-component blind hole 41, both of which are connected to the outside; the sub-component valve core 4 is provided with a sub-component sealing ring 45, which cooperates with the sub-component stepped hole 31 at the axis of the sub-component 3 to achieve sealing; the sub-component valve core 4 is provided with a positioning area 44, which cooperates with the sub-component stepped hole 31 to achieve axial unilateral positioning; the positioning area 44 is also provided with a sub-component spring 36 to constrain the sub-component valve core 4 to cooperate with the sub-component stepped hole 31.

[0039] When the female component 1 and the female component 3 are inserted and assembled, the female component valve core 4 and the female component valve core 5 are pressed against each other. After the female component valve core 5 overcomes the elastic force of the female component valve core spring 56 and moves to the right, the annular protrusion 19 disengages from the female component sealing ring 55, and the female component side wall hole 52 and the female component blind hole 51 become conductive, allowing high-pressure liquid or high-pressure gas to flow from the female component 1 side to the female component 3 side. At the same time, the female component valve core 4 overcomes the elastic force of the female component spring 36 and moves to the left, making both the female component side wall hole 42 and the female component blind hole 41 conductive to the outside, allowing high-pressure liquid or high-pressure gas to flow from the female component 1 side to the female component 3 side.

[0040] In the above embodiments, the external connector 6 consists of a right-angle anti-detachment zone 61, a stop ring 62, and a connecting thread 63. In specific embodiments, the right-angle anti-detachment zone 61 can be a zero-angle design or adopt a design such as... Figure 8 The angled anti-detachment zone 64 shown is adapted to actual operating conditions; the connecting thread 63 can also be flexibly replaced with different thread outer diameters.
