[0018] Optionally, the plug comprises a plug body and a mating portion connected to each other,

[0019] When the plug moves toward the inside of the plug cavity, the matching portion is adapted to abut against the locking member and drive the locking member to move toward the housing;

[0020] When the plug is inserted into the insertion cavity, the locking member is in the initial position and abuts against the first side wall surface of the matching portion facing the outside of the insertion cavity to prevent the matching portion from moving.

[0021] Optionally, the mating portion includes a second side wall surface, the second side wall surface faces the inside of the plug cavity, and the second side wall surface gradually inclines toward the center position of the plug along the length direction of the plug.

[0023] Optionally, the matching portion further includes a plane, wherein the plane connects the first side wall surface and the second side wall surface.

[0029] In the quick-connect socket of the embodiment of the present application, the locking member is movably arranged in the guide hole, and the locking member is limited by the limiting part, so that the locking member will not fall into the plug-in cavity when it is in the initial state, thereby simplifying the limiting structure of the locking member.

[0046] The technical solutions in the embodiments of the present application will be described clearly and completely below in conjunction with the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all of the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative work are within the scope of protection of the present application.

[0047] According to the first aspect of this application, see Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 The present disclosure provides a quick-connect socket. The quick-connect socket includes a sleeve 1 and a locking member 2. The sleeve 1 includes a shell 11 and a valve body 12. The shell 11 is sleeved on the valve body 12. A plug-in cavity 121 for plugging a plug 3 is formed in the valve body 12. A guide hole 122 communicating with the plug-in cavity 121 is provided on the valve body 12. At least one of the shell 11 and the valve body 12 forms a limiting portion 13. The locking member 2 is movably arranged in the guide hole 122. The locking member 2 can move between an initial position and an extrusion position. When the locking member 2 is in the initial position, one end of the locking member 2 is located in the plug-in cavity 121 to prevent the plug 3 from leaving the plug-in cavity 121. The other end of the locking member 2 abuts against the limiting portion 13. The limiting portion 13 can prevent the locking member 2 from moving toward the plug-in cavity 121. When the locking member 2 moves toward the shell 11 to the extrusion position, the locking member 2 unlocks the plug 3 so that the plug 3 can leave the plug-in cavity 121.

[0048] It can be understood that the valve body 12 of the sleeve 1 is formed with an inserting cavity 121, so that the plug 3 can be inserted into the inserting cavity 121 to achieve the matching of the plug 3 and the quick-connect socket.

[0049] When the plug 3 is inserted into the plug cavity 121, the locking member 2 moves toward the housing 11 to the extrusion position, so that the locking member 2 does not block the plug 3, that is, the plug 3 can freely enter and exit the plug cavity 121. When the plug 3 is inserted into the plug cavity 121, that is, the plug 3 has been inserted into place, the locking member 2 is in the initial position, and one end of the locking member 2 is located in the plug cavity 121. The one end of the locking member 2 can block the plug 3 from leaving the plug cavity 121, thereby locking the plug 3. At the same time, the limiting portion 13 abuts against the other end of the locking member 2 to prevent the locking member 2 from continuing to move into the plug cavity 121, thereby limiting the locking member 2, so that the locking member 2 can limit and lock the plug 3, and will not completely fall into the plug cavity 121, so that the locking member 2 can remain in the initial position.

[0050] When the plug 3 needs to be separated from the insertion cavity 121 , the locking member 2 is placed in the squeeze position to unlock the plug 3 , so that the plug 3 can leave the insertion cavity 121 .

[0051] That is to say, by movably setting the locking member 2 in the guide hole 122 and limiting the locking member 2 by the limiting portion 13, the locking member 2 will not fall into the plug cavity 121 when it is in the initial state, thereby simplifying the limiting structure of the locking member 2. When the plug 3 is inserted or removed, the locking member 2 can be placed in an extruded state, at which time the locking member 2 will not affect the insertion and removal of the plug 3, and the plug 3 can freely enter and exit the plug cavity 121; after the plug 3 is inserted, the locking member 2 is switched from the extruded state to the initial state, at which time the locking member 2 is on the moving path of the plug 3, and the locking member 2 can prevent the plug 3 from leaving the plug cavity 121, thereby locking the plug 3, and further realizing the quick plug-in and matching of the plug 3 and the quick socket, and the overall structure is simpler.

[0052] In some examples, when the plug 3 is inserted, the plug 3 drives the locking member 2 to move, so that the locking member 2 moves to the extrusion position toward the housing 11. Alternatively, the locking member 2 may be driven to move to the extrusion position toward the housing 11 by other structures. For example, a movable structure connected to the locking member 2 (such as a lever protruding from the housing 11 and movable relative to the housing 11) may be provided, and the locking member 2 may be driven to move to the extrusion position toward the housing 11 by the movable structure.

[0053] The quick-connect plugs in the related art, such as CN212430113U, are provided with two rows of balls, and the diameters of the two rows of balls are different, so the structure is relatively complicated, and it is easy to mix materials or install misalignment during the assembly process, such as small balls are installed in the position of large balls or large balls are installed in the position of small balls, which seriously affects the performance quality of the quick-connect plug products. However, the present application only needs a locking member 2, which has a simpler structure and will not cause mixing materials or installation misalignment.

[0054] In order to ensure that the locking member 2 can move and not fall off, a relatively complex structure is designed in the related art to limit the locking member 2. However, the present application uses the limiting portion 13 to prevent the locking member 2 from continuing to move into the plug-in cavity 121 in the initial state, thereby preventing the locking member 2 from falling off the guide hole 122, and realizing the limiting of the locking member 2 by a simple structure.

[0055] In some embodiments, see Figure 1 , Figure 2 and Figure 3 The quick-connect socket also includes an elastic locking member 4, which is arranged between the shell 11 and the valve body 12. When the locking member 2 is in the initial position, the elastic locking member 4 applies an elastic force to the locking member 2 to keep the locking member 2 in the initial position. When the locking member 2 is in the extrusion position, the elastic locking member 4 is squeezed by the locking member 2 and is in elastic deformation.

[0056] It can be understood that, in the initial position, the locking member 2 is limited by the limiting portion 13 and cannot move into the plug-in cavity 121. At the same time, the elastic locking member 4 applies an elastic force to the locking member 2, so that the locking member 2 cannot move away from the plug-in cavity 121, so that the locking member 2 remains in the initial position. When the locking member 2 is in the initial position, it can effectively block the plug 3 from leaving the plug-in cavity 121, thereby ensuring the locking effect of the plug 3.

[0057] When the plug 3 needs to be pulled out of the insertion cavity 121 or inserted into the insertion cavity 121, the locking member 2 moves toward the housing 11 to the squeeze position. During the movement of the locking member 2, the locking member 2 gradually squeezes the elastic locking member 4. When the locking member 2 is in the squeeze position, the elastic locking member 4 is squeezed by the locking member 2 and is in an elastically deformed state. When the plug 3 is inserted into the designated position or the plug 3 is pulled out of the insertion cavity 121, the elastic locking member 4 recovers its deformation and applies elastic force to the locking member 2, so that the locking member 2 returns to the initial position, thereby realizing the automatic reset of the locking member 2.

[0058] In some embodiments, see Figure 2 , Figure 3 , Figure 4 and Figure 8 The limiting portion 13 includes a limiting block 131 protruding from the inner wall surface of the outer shell 11. Along the axial direction of the valve body 12, the limiting block 131 is located on the side of the locking member 2 away from the elastic locking member 4. When the locking member 2 is in the initial position, the limiting block 131 abuts against the other end of the locking member 2 to prevent the locking member 2 from moving toward the plug-in cavity 121.

[0059] It can be understood that when the locking member 2 is in the initial position, the other end of the locking member 2 abuts against the limit block 131. Since the limit block 131 is arranged on the side of the locking member 2 away from the elastic locking member 4, the limit block 131 can prevent the locking member 2 from continuing to move in the direction away from the elastic locking member 4, that is, it can prevent the locking member 2 from continuing to move into the plug-in cavity 121, and can prevent the locking member 2 from still moving into the plug-in cavity 121 after being in the initial state, so that the locking member 2 can be stably in the initial state.

[0060] It can be understood that the limit block 131 is set on the side of the locking member 2 away from the elastic locking member 4, so that the limit block 131 will not block the locking member 2 from moving toward the elastic locking member 4, that is, in the direction away from the plug-in cavity 121, so that the locking member 2 can switch from the initial state to the extrusion state.

[0061] In some embodiments, see Figure 3 Along the axial direction of the valve body 12 , a slot 21 is formed on the side of the locking member 2 away from the elastic locking member 4 . When the locking member 2 is in the initial position, the limiting block 131 is engaged with the slot 21 .

[0062] It is understandable that when the locking member 2 is in the initial position, the limiting block 131 is engaged with the slot 21 , so that the limiting block 131 can effectively limit the locking member 2 and prevent the locking member 2 from continuing to move into the insertion cavity 121 .

[0063] In some embodiments, the housing 11 can move relative to the valve body 12 so that the limiting block 131 drives the locking member 2 to move from the initial position to the extrusion position.

[0064] It is understandable that when the plug 3 needs to be pulled out of the insertion cavity 121 or the plug 3 needs to be inserted into the insertion cavity 121, the locking member 2 needs to be switched from the initial position to the squeeze position. In this embodiment, the housing 11 is arranged to be movable relative to the valve body 12. By driving the housing 11 to move, the limit block 131 can be driven to move, and the locking member 2 can be driven to move through the limit block 131, so that the locking member 2 moves from the initial position to the squeeze position, which is simple and convenient.

[0065] It can be understood that, in the initial position, the limit block 131 serves to limit the locking member 2. When the locking member 2 needs to be switched from the initial position to the extrusion position, the limit block 131 serves to drive the locking member 2 to move, so that the limit block 131 has at least two functions at the same time, simplifying the structure of the quick-connect socket.

[0066] In some examples, in the initial state, the locking member 2 is at least partially located on the moving path of the limiting block 131 .

[0067] In some embodiments, see Figure 6 , Figure 7 The locking member 2 includes a connecting block 22 and a main body 23, wherein the connecting block 22 is connected to one end of the main body 23, and the other end of the main body 23 is passed through the guide hole 122, and the diameter of the connecting block 22 is greater than the diameter of the guide hole 122;

[0068] The limiting portion 13 includes a limiting surface 132 formed on the outer surface of the valve body 12 . When the locking member 2 is in the initial position, the limiting surface 132 abuts against the connecting block 22 to prevent the locking member 2 from moving toward the inserting cavity 121 .

[0069] It can be understood that the main body 23 of the locking member 2 can move relative to the guide hole 122, and the diameter of the connecting block 22 of the locking member 2 is set to be larger than the diameter of the guide hole 122. Then, when the connecting block 22 moves to the orifice of the guide hole 122, the connecting block 22 will be blocked by the limiting surface 132 on the outer surface of the valve body 12 and cannot continue to move into the guide hole 122, thereby achieving the limitation of the locking member 2, making it impossible for the locking member 2 to continue to move into the plug-in cavity 121, and preventing the locking member 2 from moving into the plug-in cavity 121 after being in the initial state, so that the locking member 2 can be stably in the initial state.

[0070] In some embodiments, a protrusion is formed on the inner wall surface of the housing 11 , and along the axial direction of the valve body 12 , the protrusion is located on a side of the connecting block 22 away from the elastic locking member 4 , and the connecting block 22 is located on the moving path of the protrusion.

[0071] The housing 11 can move relative to the valve body 12 so that the projection drives the locking member 2 to move from an initial position to a squeeze position.

[0072] It is understandable that when the plug 3 needs to be pulled out of the insertion cavity 121 or the plug 3 needs to be inserted into the insertion cavity 121, the locking member 2 needs to be switched from the initial position to the squeeze position. In this embodiment, the housing 11 is arranged to be movable relative to the valve body 12. By driving the housing 11 to move, the projection can be driven to move, and the locking member 2 can be driven to move through the projection, so that the locking member 2 moves from the initial position to the squeeze position, which is simple and convenient.

[0073] In some examples, in the initial state, the connection block 22 is at least partially located on the moving path of the projection.

[0074] In some embodiments, the guide hole 122 faces from the inner wall of the valve body 12 to the outer wall of the valve body 12 , and extends obliquely toward the elastic locking component 4 .

[0075] It can be understood that the guide hole 122 is arranged to be inclined toward the elastic locking member 4 so that the guide hole 122 can guide the locking member 2 to the elastic locking member 4 .

[0076] In some embodiments, see Figure 1 The elastic locking member 4 includes a locking ring 41 and a third elastic member 42 . The locking ring 41 and the third elastic member 42 are both sleeved on the valve body 12 . The locking ring 41 is located between the third elastic member 42 and the locking member 2 .

[0077] It is understandable that when the locking member 2 is in the initial position, the third elastic member 42 exerts an elastic force on the locking ring 41 toward the locking member 2, and the locking ring 41 transmits the elastic force to the locking member 2 to prevent the locking member 2 from moving, so that the locking member 2 remains in the initial position. When the locking member 2 is in the extrusion position, the locking member 2 extrudes the locking ring 41, and the locking ring 41 extrudes the third elastic member 42, causing the third elastic member 42 to deform.

[0078] For some examples, see Figure 7A guide slope 411 is formed on one side of the locking ring 41 close to the locking member 2, and the guide slope 411 abuts against the locking member 2. When the locking member 2 switches from the initial position to the extrusion position, the locking member 2 moves toward the locking ring 41. At this time, the guide slope 411 can guide the locking member 2, so that the locking member 2 can move along the guide slope 411 and push the locking ring 41 away from the guide hole 122.

[0079] According to a second aspect of the present application, the present disclosure provides a connector assembly. Figure 4 , Figure 5 and Figure 6 The connector assembly includes a plug 3 and the above-mentioned quick-connect socket, and the plug 3 can move relative to the plug-in cavity 121.

[0080] It is understandable that the connector assembly of the present application simplifies the limiting structure of the locking member 2 by movably setting the locking member 2 in the guide hole 122 and limiting the locking member 2 by the limiting portion 13, so that the locking member 2 will not fall into the plug-in cavity 121 when it is in the initial state. When the plug 3 is inserted or removed, the locking member 2 can be placed in an extruded state, at which time the locking member 2 will not affect the insertion and removal of the plug 3, and the plug 3 can freely enter and exit the plug-in cavity 121; after the plug 3 is inserted, the locking member 2 is switched from the extruded state to the initial state, at which time the locking member 2 is on the moving path of the plug 3, and the locking member 2 can prevent the plug 3 from leaving the plug-in cavity 121, thereby locking the plug 3, and then the plug 3 and the quick socket can be quickly plugged in and out, and the overall structure is simpler.

[0081] In some embodiments, see Figure 2 The plug 3 includes a plug body 31 and a mating portion 32 which are connected to each other.

[0082] When the plug 3 moves toward the inside of the plug cavity 121 , the matching portion 32 is adapted to abut against the locking member 2 and drive the locking member 2 to move toward the housing 11 .

[0083] When the plug 3 is inserted into the insertion cavity 121 , the locking member 2 is in an initial position and abuts against a first side wall surface 321 of the matching portion 32 facing outside the insertion cavity 121 to prevent the matching portion 32 from moving.

[0084] It can be understood that when the plug 3 is inserted into the plug cavity 121, the mating portion 32 can drive the locking member 2 to move, so that the locking member 2 switches from the initial position to the extrusion position, that is, the plug 3 can drive the locking member 2 to move to the extrusion position during the insertion process, thereby simplifying the structure of the quick plug assembly.

[0085] When the plug 3 is inserted into the insertion cavity 121, the matching portion 32 can abut and cooperate with the locking member 2, so that the locking member 2 can prevent the plug 3 from moving, thereby locking the plug 3 and simplifying the structure of the quick plug assembly.

[0086] In some examples, when the plug 3 is not inserted into the insertion cavity 121 , the locking member 2 is in the initial position, and the elastic locking member 4 abuts against the locking member 2 and applies an elastic force to the locking member 2 , so that the locking member 2 remains in the initial position.

[0087] When the plug 3 is inserted into the insertion cavity 121, since the locking member 2 is located on the moving path of the plug 3, the plug 3 will first contact the locking member 2 and push the locking member 2 to the extrusion position, so that the locking member 2 squeezes the elastic locking member 4. At this time, the locking member 2 will not block the movement of the plug 3, so that the plug 3 can continue to move into the insertion cavity 121. When the plug 3 is fully inserted into the insertion cavity 121, the locking member 2 will return to the initial position. At this time, the locking member 2 no longer squeezes the elastic locking member 4, and the elastic locking member 4 will restore its deformation and apply elastic force to the locking member 2 to prevent the locking member 2 from moving to the extrusion position, so that the locking member 2 can lock the plug 3 in the insertion cavity 121, and realize the quick connection between the plug 3 and the sleeve 1.

[0088] That is to say, the present application movably arranges the locking member 2 in the guide hole 122. When the plug 3 is inserted, the plug 3 can push the locking member 2 from the initial position to the extrusion position, and the locking member 2 squeezes the elastic locking member 4. When the plug 3 is inserted into the plug-in cavity 121, the plug 3 no longer squeezes and pushes the locking member 2, and the elastic locking member 4 will restore its deformation and apply elastic force to the locking member 2, and the locking member 2 returns to the initial position, that is, the locking member 2 returns to the moving path of the plug 3 again. At this time, the locking member 2 is kept in the initial position by the resistance pressure of the elastic locking member 4, so that the locking member 2 can lock the plug 3, thereby realizing the rapid insertion of the plug 3 and the sleeve 1, and the overall structure is simpler.

[0089] In some embodiments, see Figure 2 The mating portion 32 includes a second side wall surface 322 , the second side wall surface 322 faces the inside of the plug cavity 121 , and the second side wall surface 322 gradually inclines toward the center position of the plug 3 along the length direction of the plug 3 .

[0090] When the plug 3 moves into the inserting cavity 121 , the second side wall surface 322 abuts against the locking member 2 .

[0091] It is understandable that when the plug 3 moves into the insertion cavity 121, the locking member 2 is located on the moving path of the second side wall surface 322, that is, as the plug 3 is inserted, the second side wall surface 322 will abut against the locking member 2. As the plug 3 continues to be inserted, the second side wall surface 322 will drive the locking member 2 to move toward the elastic locking member 4. At the same time, since the second side wall surface 322 is inclined, the second side wall surface 322 and the locking member 2 will also move relative to each other. The second side wall surface 322 can gradually push the locking member 2 away from the insertion cavity 121, so that the locking member 2 moves to a squeezed state, so that the locking member 2 will not prevent the insertion of the plug 3, so that the plug 3 can continue to move into the insertion cavity 121.

[0092] In some embodiments, see Figure 2 The matching portion 32 further includes a plane 323 , and the plane 323 connects the first side wall surface 321 and the second side wall surface 322 .

[0093] When the plug 3 moves into the insertion cavity 121 , the locking member 2 abuts against the second side wall surface 322 and the plane 323 in sequence.

[0094] It can be understood that when the second side wall surface 322 abuts against the locking member 2, as the plug 3 moves, the second side wall surface 322 can drive the locking member 2 to gradually move away from the plug-in cavity 121, and when the first side wall surface 321 abuts against the locking member 2, the plug 3 has been inserted into the plug-in cavity 121, and the locking member 2 locks the plug 3.

[0095] In this embodiment, the plane 323 is used to connect the first side wall surface 321 and the second side wall surface 322. After the second side wall surface 322 pushes the locking member 2 to the extrusion position, the locking member 2 will abut against the plane 323. At this time, the plane 323 can keep the locking member 2 in the extrusion state, and the plug 3 can continue to move into the plug cavity 121. When the plug 3 is inserted into the plug cavity 121, the locking member 2 is disengaged from the plane 323 and contacts the first side wall surface 321, ensuring that after the plug 3 is inserted into the plug cavity 121, the locking member 2 will return to the initial position to prevent the movement of the plug 3.

[0096] In some embodiments, see Figure 2 The plug 3 also includes a first elastic member 33 , one end of which is connected to the plug body 31 . When the plug 3 is inserted into the insertion cavity 121 , the sleeve 1 abuts against the other end of the first elastic member 33 and squeezes the first elastic member 33 .

[0097] It is understandable that when the plug 3 is inserted into the insertion cavity 121, the sleeve 1 will squeeze the first elastic member 33. Then, when the locking member 2 no longer locks the plug 3, the first elastic member 33 will restore its deformation, and the elastic force of the first elastic member 33 will drive the plug 3 to move away from the sleeve 1, so that the plug 3 can be automatically disengaged.

[0098] In some examples, the sleeve 1 further includes a ejector pin, which is fixedly mounted on the valve body 12 . When the plug 3 is inserted into the insertion cavity 121 , the ejector pin is on the moving path of the first elastic member 33 , and the ejector pin squeezes the first elastic member 33 , causing the first elastic member 33 to deform.

[0099] In some embodiments, see Figure 1 The sleeve 1 includes a second elastic member 14 , one end of which is connected to the valve body 12 . When the plug 3 is inserted into the insertion cavity 121 , the plug 3 abuts against the other end of the second elastic member 14 and squeezes the second elastic member 14 .

[0100] It is understandable that when the plug 3 is inserted into the insertion cavity 121, the plug 3 will squeeze the second elastic member 14. Then, when the locking member 2 no longer locks the plug 3, the second elastic member 14 will restore its deformation, and the elastic force of the second elastic member 14 will drive the plug 3 to move away from the sleeve 1, so that the plug 3 can be automatically disengaged.

[0101] In some examples, the second elastic member 14 includes a piston and a spring, the piston is disposed in the insertion cavity 121, and the spring is located between the bottom wall of the insertion cavity 121 and the piston. When the plug 3 is inserted into the insertion cavity 121, the plug 3 presses the piston, and the piston presses the spring.

[0102] According to a third aspect of the present application, the present disclosure provides a refrigeration system, which includes the quick-connect socket or the connector assembly as described above.

[0103] It is understandable that, in a refrigeration system with a quick-connect socket or a plug-in assembly, the locking member 2 is movably arranged in the guide hole 122, and the locking member 2 is limited by the limiting portion 13, so that the locking member 2 will not fall into the plug-in cavity 121 when in the initial state, thereby simplifying the limiting structure of the locking member 2. When the plug 3 is inserted or removed, the locking member 2 can be placed in an extruded state, at which time the locking member 2 will not affect the insertion and removal of the plug 3, and the plug 3 can freely enter and exit the plug-in cavity 121; after the plug 3 is inserted, the locking member 2 is switched from the extruded state to the initial state, at which time the locking member 2 is on the moving path of the plug 3, and the locking member 2 can prevent the plug 3 from leaving the plug-in cavity 121, thereby locking the plug 3, and then the plug 3 and the quick socket can be quickly plugged in and out, and the overall structure is simpler.

[0104] According to a fourth aspect of the present application, the present disclosure provides a server, which includes the refrigeration system as described above.

[0105] It is understandable that, in a server with a refrigeration system, the locking member 2 is movably arranged in the guide hole 122, and the locking member 2 is limited by the limiting portion 13, so that the locking member 2 will not fall into the plug-in cavity 121 when in the initial state, thereby simplifying the limiting structure of the locking member 2. When the plug 3 is inserted or removed, the locking member 2 can be placed in an extruded state, at which time the locking member 2 will not affect the insertion and removal of the plug 3, and the plug 3 can freely enter and exit the plug-in cavity 121; after the plug 3 is inserted, the locking member 2 is switched from the extruded state to the initial state, at which time the locking member 2 is on the moving path of the plug 3, and the locking member 2 can prevent the plug 3 from leaving the plug-in cavity 121, thereby locking the plug 3, and then the plug 3 and the quick socket can be quickly plugged in and out, and the overall structure is simpler.
