[0043] Next, the technical solutions in the embodiments of the present application will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present application. Obviously, the described embodiments are only a part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative efforts fall within the protection scope of the present application.

[0044] According to the first aspect of the present application, please refer to Figure 1 , Figure 2 , Figure 3 , Figure 4 and Figure 5 , the present disclosure provides a quick connector plug. The quick connector plug includes a sleeve 1, an elastic locking member 4, a plug 3, and a locking member 2. The sleeve 1 includes an outer shell 11 and a valve body 12. The outer shell 11 is sleeved on the valve body 12. The valve body 12 is formed with an insertion cavity 121 and an activity groove 122. The elastic locking member 4 is movably arranged between the outer shell 11 and the valve body 12. The plug 3 can move relative to the insertion cavity 121. The locking member 2 is movably arranged in the activity groove 122. The locking member 2 can be switched between an initial position and a pressing position. In the initial position, the locking member 2 is located on the moving path of the plug 3. In the pressing position, the locking member 2 presses the elastic locking member 4;

[0045] When the plug 3 moves inward into the insertion cavity 121, the plug 3 drives the locking member 2 to move toward the elastic locking member 4, so that the locking member 2 moves from the initial position to the pressing position;

[0046] When the plug 3 is inserted into the insertion cavity 121, the locking member 2 is in the initial position, and the elastic locking member 4 applies an elastic force to the locking member 2 to prevent the locking member 2 from moving.

[0047] It can be understood that 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 is kept in the initial position.

[0048] 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 pressing position, so that the locking member 2 presses the elastic locking member 4. At this time, the locking member 2 does not block the movement of the plug 3, so that the plug 3 can continue to move inside the insertion cavity 121. When the plug 3 is completely 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 presses the elastic locking member 4, and the elastic locking member 4 will recover its deformation and apply an elastic force to the locking member 2 to prevent the locking member 2 from moving to the pressing position, so that the locking member 2 can lock the plug 3 in the insertion cavity 121, realizing the quick connection of the plug 3 and the sleeve 1.

[0049] That is to say, in this application, the locking member 2 is movably arranged in the movable groove 122. When the plug 3 is inserted, the plug 3 can push the locking member 2 from the initial position to the pressing position, and the locking member 2 presses the elastic locking member 4. When the plug 3 is inserted into the insertion cavity 121, the plug 3 no longer presses and pushes the locking member 2, and the elastic locking member 4 will recover its deformation and apply an elastic force to the locking member 2. 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 held in the initial position by the pressing force of the elastic locking member 4, so that the locking member 2 can lock the plug 3, realizing the quick insertion of the plug 3 and the sleeve 1, and the overall structure is simpler.

[0050] The quick connector plug 3 in the related art, such as CN212430113U, is provided with two rows of balls in the front and back, and the diameters of the two rows of balls in the front and back are different. The structure is relatively complex, and material mixing or installation misalignment is likely to occur during the assembly process, such as small balls being installed in the position of large balls or large balls being installed in the position of small balls, which seriously affects the performance and quality of the quick connector plug 3 product. And this application only needs one locking member 2, the structure is simpler, and there will be no situation of material mixing or installation misalignment.

[0051] In some embodiments, refer to Figure 2 , the plug 3 includes a mating portion 32,

[0052] When the plug 3 moves inside the insertion cavity 121, the mating portion 32 is adapted to abut against the locking member 2 and drive the locking member 2 to move towards the elastic locking member 4;

[0053] When the plug 3 is inserted into the insertion cavity 121, the locking member 2 is in the initial position and abuts against the first side wall surface 321 of the mating portion 32 facing outside the insertion cavity 121 to prevent the mating portion 32 from moving.

[0054] It is understandable that the plug 3 is formed with a mating portion 32. When the plug 3 moves into the insertion cavity 121, the locking member 2 is located on the moving path of the mating portion 32. The mating portion 32 will abut against the locking member 2. As the plug 3 continues to move, the mating portion 32 will drive the locking member 2 to move towards the elastic locking member 4. That is, during the insertion process of the plug 3, the locking member 2 will be driven to squeeze the elastic locking member 4.

[0055] During the process of the plug 3 being inserted into the insertion cavity 121, the locking member 2 will move from the initial position to the squeezing position. As the plug 3 continues to be inserted, that is, when the plug 3 is inserted into the insertion cavity 121 and the plug 3 can no longer move further into the insertion cavity 121, the locking member 2 will move from the squeezing position to the initial position. At this time, the locking member 2 will abut against the first side wall surface 321 of the mating portion 32 facing outside the insertion cavity 121, so that the locking member 2 can prevent the mating portion 32 from moving outside the insertion cavity 121, thereby realizing the locking of the plug 3.

[0056] In some embodiments, referring to Figure 2 , the mating portion 32 includes a second side wall surface 322. The second side wall surface 322 faces the inside of the insertion cavity 121 and gradually inclines towards the central position of the plug 3 along the length direction of the plug 3.

[0057] When the plug 3 moves towards the inside of the insertion cavity 121, the second side wall surface 322 abuts against the locking member 2.

[0058] 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 towards the elastic locking member 4. At the same time, since the second side wall surface 322 is inclined, relative movement will also occur between the second side wall surface 322 and the locking member 2. The second side wall surface 322 can gradually push the locking member 2 in the direction away from the insertion cavity 121, so that the locking member 2 moves to the squeezing state, so that the locking member 2 does not prevent the insertion of the plug 3, so that the plug 3 can continue to move into the insertion cavity 121.

[0059] In some embodiments, referring to Figure 2 , the mating portion 32 further includes a flat surface 323. The flat surface 323 connects the first side wall surface 321 and the second side wall surface 322.

[0060] When the plug 3 moves into the insertion cavity 121, the locking member 2 abuts against the second side wall surface 322 and the flat surface 323 in sequence.

[0061] 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.

[0062] 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.

[0063] In some embodiments, see Figure 6 and Figure 7 The housing 11 can move relative to the valve body 12 , and the housing 11 is used to drive the elastic locking member 4 to move away from the locking member 2 .

[0064] It can be understood that when the plug 3 needs to be separated from the sleeve 1, the shell 11 is moved relative to the valve body 12, and the shell 11 is used to drive the elastic locking member 4 to move away from the locking member 2, that is, the elastic locking member 4 is disconnected from the locking member 2, and the elastic locking member 4 no longer applies an elastic force to the locking member 2. At this time, the locking member 2 can move away from the plug-in cavity 121. At this time, a force is applied to the plug 3 toward the outside of the plug-in cavity 121, and the plug 3 can push the locking member 2 to the extrusion position. The locking member 2 will not block the movement of the plug 3, so that the plug 3 can be smoothly separated from the sleeve 1.

[0065] After the plug 3 is separated from the sleeve 1, no external force is applied to the shell 11, and the elastic locking member 2 will restore its deformation and drive the shell 11 to reset. At the same time, if the locking member 2 has not returned to the initial position, the elastic locking member 2 will move toward the locking member 2 when restoring its deformation and push the locking member 2 to the initial position, thereby resetting the locking member 2.

[0066] In some embodiments, see Figure 1 , Figure 6 and Figure 7 A protrusion 111 is formed on the inner wall surface of the housing 11 . Along the axial direction of the valve body 12 , the protrusion 111 is located on a side of the elastic locking member 4 close to the locking member 2 . The elastic locking member 4 is located on the moving path of the protrusion 111 .

[0067] It can be understood that the convex portion 111 is located on the side of the elastic locking member 4 close to the locking member 2. When it is necessary to unlock the plug 3, the housing 11 moves towards the elastic locking member 4. The convex portion 111 will move along with it towards the elastic locking member 4, and the convex portion 111 can drive the elastic locking member 4 to move away from the locking member 2, so that the elastic locking member 4 is disengaged from the locking member 2.

[0068] In some examples, the convex portion 111 is spaced from the locking member 2, and the convex portion 111 will not affect the movement of the locking member 2.

[0069] In some embodiments, referring to Figure 2 , the plug 3 includes a plug body 31 and a first elastic member 33. One end of the first elastic member 33 is connected to the plug body 31. When the plug 3 is inserted into the insertion cavity 121, the sleeve 1 abuts against and presses the other end of the first elastic member 33.

[0070] It can be understood that when the plug 3 is inserted into the insertion cavity 121, the sleeve 1 will press the first elastic member 33. Then when the locking member 2 no longer locks the plug 3, the first elastic member 33 will recover its deformation, and at the same time, the elastic force of the first elastic member 33 will drive the plug 3 to move away from the sleeve 1, realizing the automatic detachment of the plug 3.

[0071] In some examples, the sleeve 1 further includes a thimble, which is fixedly installed on the valve body 12. When the plug 3 is inserted into the insertion cavity 121, the thimble is on the movement path of the first elastic member 33, and the thimble will press the first elastic member 33, causing the first elastic member 33 to deform.

[0072] In some embodiments, referring to Figure 1 , the sleeve 1 includes a second elastic member 14. One end of the second elastic member 14 is connected to the valve body 12. When the plug 3 is inserted into the insertion cavity 121, the plug 3 abuts against and presses the other end of the second elastic member 14.

[0073] It can be understood that when the plug 3 is inserted into the insertion cavity 121, the plug 3 will press the second elastic member 14. Then when the locking member 2 no longer locks the plug 3, the second elastic member 14 will recover its deformation, and at the same time, the elastic force of the second elastic member 14 will drive the plug 3 to move away from the sleeve 1, realizing the automatic detachment of the plug 3.

[0074] In some examples, the second elastic member 14 includes a piston and a spring. The piston is arranged 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 will press the piston, and the piston presses the spring.

[0075] In some embodiments, at the extrusion position, the locking member 2 at least partially protrudes from the valve body 12, and at the initial position, the locking member 2 is at least partially located within the insertion cavity 121.

[0076] It can be understood that at the initial position, the locking member 2 is at least partially located within the insertion cavity 121, that is, at least a part of the locking member 2 is on the moving path of the plug 3, so that the locking member 2 can effectively lock the plug 3. At the extrusion position, the locking member 2 at least partially protrudes from the valve body 12, ensuring that the locking member 2 can extrude the elastic locking element 4.

[0077] In some embodiments, the movable groove 122 extends along the axial direction of the valve body 12. At the initial position, along the axial direction of the valve body 12, the locking member 2 is located at one end of the movable groove 122 away from the elastic locking element 4.

[0078] It can be understood that at the initial position, the locking member 2 is located at one end of the movable groove 122 away from the elastic locking element 4, that is, at this time, the locking member 2 is blocked by the end face of the movable groove 122 and cannot move away from the elastic locking element 4, and can only move towards the elastic locking element 4. Then when the plug 3 is inserted, driven by the plug 3, the locking member 2 will move towards the elastic locking element 4 and extrude the elastic locking element 4, so that the plug 3 can be smoothly inserted. When the plug 3 is inserted into the insertion cavity 121, the locking member 2 returns to the initial position, and the elastic locking element 4 will apply an elastic force to the locking member 2. At this time, the locking member 2 is blocked by the end face of the movable groove 122 on one side and cannot move, and is blocked by the elastic locking element 4 on the other side and cannot move, so that the locking member 2 can be stably in the initial position, ensuring that the plug 3 can be stably and effectively locked.

[0079] In some embodiments, referring to Figure 1 , the elastic locking element 4 includes a locking ring 41 and a third elastic member 42. Both the locking ring 41 and the third elastic member 42 are sleeved on the valve body 12, and the locking ring 41 is located between the third elastic member 42 and the locking member 2.

[0080] It can be understood that when the locking member 2 is in the initial position, the third elastic member 42 will apply an elastic force towards the locking member 2 to the locking ring 41, and the locking ring 41 will transfer 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 will extrude the locking ring 41, and the locking ring 41 will extrude the third elastic member 42, causing the third elastic member 42 to deform.

[0081] In some examples, a guiding inclined surface is formed on one side of the buckle ring 41 close to the locking member 2. The guiding inclined surface abuts against the locking member 2. When the locking member 2 switches from the initial position to the pressing position, the locking member 2 moves towards the buckle ring 41. At this time, the guiding inclined surface can play a guiding role for the locking member 2, so that the locking member 2 can move along the guiding inclined surface and push the buckle ring 41 in a direction away from the movable groove 122.

[0082] In some embodiments, the locking member 2 includes locking balls. It should be noted that only an example of the locking member 2 is given here. The locking member 2 can also be any other suitable structural member, such as an elliptical block.

[0083] In some examples, the movable groove 122 includes an inner groove hole and an outer groove hole that communicate with each other. The groove width of the inner groove hole is greater than the diameter of the locking ball, and the groove width of the outer groove hole is less than the diameter of the locking ball. The locking ball is movably arranged in the inner groove hole. Limiting the locking ball by the outer groove hole can prevent the locking ball from falling into the insertion cavity 121.

[0084] In some embodiments, when the quick connector plug 3 is in use:

[0085] Insert the plug 3 into the insertion cavity 121, so that the plug 3 gradually moves into the insertion cavity 121. The second side wall surface 322 of the mating portion 32 of the plug 3 will first 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, causing the locking member 2 to move axially and radially, and the locking member 2 will press the elastic locking member 4.

[0086] Then continue to insert the plug 3 into the insertion cavity 121. The plug 3 will continuously drive the locking member 2 to move towards the elastic locking member 4. When the second side wall surface 322 is disengaged from the locking member 2, the locking member 2 will contact the flat surface 323, and the locking member 2 will remain in the pressed state.

[0087] Then continue to insert the plug 3 into the insertion cavity 121. When the flat surface 323 is disengaged from the locking member 2, the plug 3 no longer exerts a thrust force on the locking member 2, and the locking member 2 no longer presses the elastic locking member 4. The elastic locking member 4 will recover its deformation. At the same time, since the mating portion 32 of the plug 3 protrudes from the plug body 31, the locking member 2 will return to the initial position and abut against the first side wall surface 321 under the action of its own gravity and / or the elastic force of the elastic locking member 4. At this time, the elastic locking member 4 will exert an elastic force on the locking member 2 to prevent the locking member 2 from moving, so that the locking member 2 can prevent the movement of the plug 3 and achieve the locking of the plug 3.

[0088] According to the second aspect of the present application, the present disclosure provides a refrigeration system. The refrigeration system includes the quick connector plug 3 as described above.

[0089] It can be understood that by movably arranging the locking member 2 in the movable slot 122, when the plug 3 is inserted, the plug 3 can push the locking member 2 from the initial position to the pressing position. The locking member 2 presses the elastic locking member 4. When the plug 3 is inserted into the insertion cavity 121, the plug 3 no longer presses and pushes the locking member 2. The elastic locking member 4 will recover its deformation and apply an elastic force to the locking member 2. 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 at the initial position by the pressing force of the elastic locking member 4, so that the locking member 2 can lock the plug 3, realizing the quick insertion of the plug 3 and the sleeve 1, and the overall structure is simpler.
