[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Please see Figure 1-7 The present invention provides the following technical solution:

[0030] The low-evaporation bidirectional shut-off connector includes a male connector metal shell 1 and a female connector right metal shell 4. A female connector left metal shell 2 is provided on the left side of the female connector right metal shell 4. A moving mechanism 8 is provided inside the female connector right metal shell 4, and a snap-fit ​​mechanism 7 is provided inside the female connector left metal shell 2.

[0031] The moving mechanism 8 includes a male connector spring 801, a male connector movable inner core 802, a female connector movable inner core 803, a female connector push rod 804, and a female connector spring 805. The male connector spring 801 is located inside the male connector metal housing 1. The left side of the male connector movable inner core 802 contacts the right side of the male connector spring 801. The right side of the female connector spring 805 contacts the surface of the female connector push rod 804. The female connector spring 805 is located inside the female connector metal right housing 4. The right side of the female connector movable inner core 803 contacts the left side of the female connector spring 805. The right side of the male connector movable inner core 802 contacts the left side of the female connector push rod 804.

[0032] In this embodiment: When it is necessary to transport the medium, the male connector metal housing 1 is inserted into the female connector left metal housing 2. The female connector push rod 804 pushes the male connector movable inner core 802, compressing the male connector spring 801. The right side of the male connector metal housing 1 pushes the female connector movable inner core 803, causing it to misalign with the female connector push rod 804. The female connector spring 805 is compressed, and the protrusion 703 engages with the elastic locking clip 702. The male connector metal housing 1 and the female connector left metal housing 2 are connected to the female connector right metal housing 4. The medium flows through the male connector movable inner core 802, the female connector movable inner core 803, and the female connector push rod 804 through the groove 12. When it is necessary to cut off the medium, the button 3 is pressed to move the elastic locking clip 702, causing it to engage with the female connector right metal housing 4. When the protrusion 703 disengages, the male connector spring 801 and the female connector spring 805 rebound. The male connector spring 801 pushes the male connector movable inner core 802 to contact the inner wall of the male connector metal housing 1, which is sealed by the first sealing ring 10. The female connector spring 805 pushes the female connector movable inner core 803 to contact the inner wall of the female connector metal left housing 2, which is sealed by the third sealing ring 14. The inner wall of the female connector movable inner core 803 is sealed with the female connector top rod 804 through the second sealing ring 11. This connector can be quickly disconnected or connected without discharging the internal medium. Moreover, the part in contact with the medium is made of metal material, which solves the problem of medium evaporation and overcomes the shortcomings of existing connectors, such as the inability to effectively suppress evaporation and the inconvenience of connection and disconnection operations, thus meeting the requirements of high-requirement scenarios.

[0033] Specifically, such as Figure 3 , Figure 5 and Figure 6As shown, the locking mechanism 7 includes two movable grooves 701, two elastic locking clips 702, and a protrusion 703. The protrusion 703 is disposed on the surface of the male connector metal housing 1, the movable grooves 701 are opened on the inner wall of the female connector metal left housing 2, and the elastic locking clips 702 are movably disposed inside the movable grooves 701.

[0034] Specifically, such as Figure 3 and Figure 4 As shown, a retaining spring 9 is engaged with the inner wall of the protrusion 703, and the left side of the male connector spring 801 contacts the right side of the retaining spring 9.

[0035] Specifically, such as Figure 4 As shown, a first sealing ring 10 is fitted on the surface of the male connector movable inner core 802, and the surface of the first sealing ring 10 is in close contact with the inner wall of the male connector metal housing 1.

[0036] In this embodiment: the elastic locking clip 702 is movably disposed inside the movable groove 701, so that the protrusion 703 can push the elastic locking clip 702 and reset it, thereby limiting the male connector metal housing 1 inside the female connector metal left housing 2. The male connector spring 801 is blocked by the snap ring 9, so that the male connector spring 801 can move freely inside the male connector metal housing 1. The male connector movable inner core 802 and the inner wall of the male connector metal housing 1 are sealed by the first sealing ring 10.

[0037] Specifically, such as Figure 4 As shown, a second sealing ring 11 is fitted on the surface of the female connector top rod 804, and the surface of the second sealing ring 11 is in close contact with the inner wall of the female connector movable inner core 803.

[0038] Specifically, such as Figure 4 As shown, both the male connector movable inner core 802 and the female connector push rod 804 have through grooves 12 inside.

[0039] In this embodiment, the female connector push rod 804 and the inner wall of the female connector movable inner core 803 are sealed by the second sealing ring 11, and the medium can flow through the male connector movable inner core 802 and the female connector push rod 804 through the through groove 12.

[0040] Specifically, such as Figure 2 and Figure 6 As shown, a button 3 is fixedly connected between the front and rear sides of the two elastic locking clips 702. The side of the button 3 near the female connector metal left housing 2 passes through the female connector metal left housing 2 and extends to the outside of the female connector metal left housing 2. The surface of the button 3 is in active contact with the inside of the female connector metal left housing 2.

[0041] Specifically, such as Figure 2As shown, a number of locking blocks 5 are fixedly connected to the surface of the left metal housing 2 of the female connector. The number of locking blocks 5 is several and they are evenly distributed on the surface of the left metal housing 2 of the female connector. The inside of the right metal housing 4 of the female connector is provided with a slot 6 that cooperates with the locking blocks 5. The locking blocks 5 are engaged in the inside of the slot 6.

[0042] In this embodiment: the button 3 is movably disposed inside the left metal housing 2 of the female connector. When the button 3 is pressed, the elastic locking clip 702 moves into the movable groove 701, which allows the elastic locking clip 702 to disengage from the protrusion 703, making it convenient to disassemble the metal housing 1 of the male connector. The left metal housing 2 of the female connector and the right metal housing 4 of the female connector are connected by the locking groove 6 and the locking block 5.

[0043] Specifically, such as Figure 7 As shown, a third sealing ring 14 is snapped into the inner wall of the female connector's metal left housing 2, and the surface of the third sealing ring 14 is in close contact with the surface of the female connector's movable inner core 803.

[0044] Specifically, such as Figure 7 As shown, a fourth sealing ring 13 is fitted on the surface of the left metal housing 2 of the female connector, and the surface of the fourth sealing ring 13 is in close contact with the inner wall of the right metal housing 4 of the female connector.

[0045] In this embodiment, the left metal housing 2 of the female connector and the movable inner core 803 of the female connector are sealed by a third sealing ring 14, and the left metal housing 2 of the female connector and the right metal housing 4 of the female connector are sealed by a fourth sealing ring 13.

[0046] Working principle: When conveying the medium, the male connector metal housing 1 is inserted into the female connector left metal housing 2. The female connector push rod 804 pushes the male connector movable inner core 802 to the left. At this time, the male connector spring 801 is compressed. Simultaneously, the right side of the male connector metal housing 1 pushes the female connector movable inner core 803 to the right, causing the female connector movable inner core 803 to be misaligned with the female connector push rod 804. At this time, the female connector spring 805 is compressed, moving the protrusion 703 to engage with the elastic locking 702. At this point, the male connector metal housing 1 and the female connector left metal housing 2 can be connected to the female connector. When the right metal housing 4 is connected, the medium can flow into the left metal housing 2 of the female connector through the through groove 12 inside the movable inner core 802 of the male connector, then through the movable inner core 803 of the female connector, and then through the through groove 12 inside the push rod 804 of the female connector. When it is necessary to cut off the medium, press the button 3. The button 3 drives the elastic locking clip 702 to move in the movable groove 701, so that the elastic locking clip 702 disengages from the protrusion 703. At this time, the male connector spring 801 and the female connector spring 805 rebound. The male connector spring 801 quickly pushes the movable inner core 802 of the male connector to the male connector. The inner wall of the connector metal housing 1 contacts the male connector's movable inner core 802, which is sealed to the inner wall of the male connector metal housing 1 by the first sealing ring 10. The female connector spring 805 quickly pushes the female connector's movable inner core 803 to contact the inner wall of the female connector's left metal housing 2, and seals it with the female connector's left metal housing 2 by the third sealing ring 14. The inner wall of the female connector's movable inner core 803 is then sealed with the female connector's push rod 804 by the second sealing ring 11. Without discharging the internal medium, the male connector metal housing 1 and the female connector's left metal housing 2 can be sealed to the female connector's right metal housing. The quick disconnection or connection of body 4 is achieved by using metal material in the part of the connector that contacts the medium, which effectively solves the problem of medium evaporation. This avoids the problem that existing connectors, when in use, cannot effectively suppress medium evaporation due to the material of the part in contact with the medium. This can lead to changes in medium characteristics in environments with high requirements for medium evaporation, affecting the normal operation of the system or even causing malfunctions. Existing connectors have shortcomings in connection and disconnection operations. They are difficult to achieve quick disconnection or connection without discharging the internal medium, which greatly affects work efficiency. In some emergency scenarios or scenarios with high requirements for ease of operation, they cannot meet the actual needs.

[0047] The above are merely preferred embodiments of the present utility model and are not intended to limit the present utility model. Any modifications, equivalent substitutions, and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
