Detailed implementation manners

[0030] The following further describes the present utility model in detail with reference to the drawings and embodiments, so that those skilled in the art can implement it according to the description in the specification.

[0031] It should be understood that the terms such as "having", "comprising" and "including" used herein do not exclude the presence or addition of one or more other elements or their combinations.

[0032] As Figures 1 - 7 shown, the present utility model provides a liquid-cooled two-way stop quick connector, including: a female head body 1 and a connection end 2. The connection end 2 is usually directly connected to the pipeline of the device. The connection end 2 is arranged at one end of the female head body 1 and is communicated with the female head body 1. A two-way stop assembly is arranged in the female head body 1, and a locking assembly is arranged on the female head body 1. The locking assembly is used to fix the female head body 1 and the male head body 3;

[0033] When the male head body 3 is connected to the female head body 1, first press the locking component, then insert the matching male head body 3 into the female head body 1. After that, release the hand, and the locking component resets. The male head body 3 is communicated with the connecting end 2 through the female head body 1. The locking component is clamped with the male head body 3, thus completing the quick connection between the male head body 3 and the female head body 1. After the male head body 3 is connected to the female head body 1, they are communicated with each other to form a passage for liquid to flow through. When disassembling, similarly, just directly press the locking component to unlock the male head body 3 from the female head body 1, and then pull out the male head body 3. After the male head body 3 is pulled out, the female head body 1 is closed by the two-way cut-off component to prevent liquid from flowing out. Then release the hand to let the locking component reset;

[0034] When the male head body 3 is not connected to the female head body 1, the two-way cut-off component seals the female head body 1, and liquid cannot enter the female head body 1 from the outside, nor can it flow from the female head body 1 to the outside, thus achieving the effect of two-way cut-off.

[0035] The working principle and beneficial effects of the above technical solution: Through the above structural design, the quick disassembly and connection of the joint can be realized. And after connection, a passage is automatically formed for liquid to flow through. After separation, a closed circuit is automatically formed to prevent liquid from flowing out. Among them, no electronic equipment is required for control, and no production stop is needed for pipeline connection. The locking component is arranged on the surface of the female head body 3 so that it can be coplanar with the female head body 3. When in use, press it into the interior of the female head body 3, which can avoid accidentally touching the locking component during daily production, resulting in the separation of the female head body 1 and the male head body 3. At the same time, even if the female head body 1 and the male head body 3 are separated due to accidental touch, at the moment of their separation, the two-way cut-off component can quickly stop the liquid in the female head body 1 to avoid liquid leakage.

[0036] In this embodiment, we provide a specific structure of the female head body 1. One end of the female head body 1 far from the connecting end 2 is provided with a cylindrical first groove, and the first groove extends into the interior of the female head body 1 and is communicated with the connecting end 2 through a communication hole arranged at the end of the first groove. The communication hole is usually in the shape of Figure 6 a horn as shown, that is, the opening diameter at the end close to the first groove is larger than the opening diameter at the end far from the first groove. The two-way cut-off component is arranged in the first groove, and the locking component is arranged on the side wall of the female head body 1 and penetrates through the first groove. The inner diameter of the first groove is larger than the inner diameter of the communication hole, and the inner diameter of the communication hole is not less than the inner diameter of the connecting end 2.

[0037] A cylindrical second groove is provided at one end of the female head body 1 away from the connection end 2. The second groove is located at the opening of the first groove, and the inner diameter of the second groove is greater than that of the first groove. The second groove and the first groove are located on the same central axis. The connection part between the second groove and the first groove is a first inclined surface 4, as Figure 6 shown;

[0038] When the mating male head body 3 is connected to the female head body 1, the first inclined surface 4 abuts against the second inclined surface 31 of the clamping member on the outer wall of the male head body 3. The male head valve stem in the male head body 3 abuts against the two-way cut-off assembly, and the two-way cut-off assembly releases the seal of the female head body 1, so that a passage is formed between the male head body 3 and the female head body 1. A cylindrical third groove is provided between the first groove and the second groove. The third groove and the first groove are located on the same central axis. The inner diameter of the third groove is smaller than that of the first groove. The second groove communicates with the first groove through the third groove. The first inclined surface 4 is located at the connection part between the second groove and the third groove, as Figure 6 shown. The connection part between the third groove and the first groove constitutes a first abutting surface 5. Since the inner diameter of the communication hole is not less than the inner diameter of the connection end 2, the inner end surface of the first groove constitutes a second abutting surface, and the two-way cut-off assembly abuts against the second abutting surface;

[0039] When the male head body 3 is not connected to the female head body 1, the two-way cut-off assembly abuts against the first abutting surface 5, thereby forming a seal for the female head body 1. At least one first annular groove is provided on the inner wall of the third groove, and a first sealing member 6 is provided in the first annular groove, as Figure 6 shown.

[0040] The locking assembly consists of a pressing member 7 provided on the side wall of the female head body 1 and a first reset member 8 provided on the side wall of the female head body 1. In order to enable the pressing member 7 to move on the female head body 1, usually the outer side wall of the pressing member 7 is a plane so that it can slide along the side wall of the female head body 1 through this plane. In order to prevent the pressing member 7 from protruding from the female head body 1 and causing accidental touch, usually the pressing surface of the pressing member 7 is an arc adapted to the outer wall of the female head body 1, and its pressing surface is coplanar with the side wall of the female head body 1, as Figure 6 shown. A first installation groove adapted to the pressing member 7 and a second installation groove adapted to the first reset member 8 are provided on the side wall of the female head body 1. The pressing member 7 is provided with a connection hole, and the inner diameter of the connection hole is not less than the inner diameter of the second groove. A limiting column connected to the first reset member 8 is provided on the pressing member 7. The first reset member 8 is provided in the second installation groove and sleeved on the limiting column, as Figure 3As shown. A first limiting member 9 is provided at the bottom of the pressing member 7, and a key positioning pin 10 is provided at the end of the female head main body 1. The first limiting member 9 can be an arc as shown in Figure 1 . Its opening faces the key positioning pin 10. When the pressing member 7 is pressed down, the first limiting member 9 can limit the moving direction and moving distance of the pressing member 7, so that when the pressing member 7 is pressed to the limit position, the first limiting member 9 abuts against the key positioning pin 10. At this time, the connection hole and the second groove are on the same central axis, so as to facilitate the quick insertion of the male head main body 3. The first limiting member 9 can also be a structure with a strip-shaped hole, and the key positioning pin 10 is located in the strip-shaped hole. The first limiting member 9 can be limited through the strip-shaped hole. When this implementation mode is adopted, the first limiting member 9 can not only limit the pressing member 7 when pressing it, but also limit it when the pressing member 7 resets, preventing the pressing member 7 from disengaging from the female head main body 1. No matter which implementation mode is selected, as long as it is ensured that the first limiting member 9 is movably connected to the key positioning pin 10.

[0041] The two-way cut-off component is composed of a female valve stem 11 arranged in the first groove, a female valve head 12 sleeved outside the female valve stem 11, and a second reset member 13. One end of the female valve stem 11 is connected to the inner end face of the first groove, and the other end extends into the third groove. One end of the second reset member 13 abuts against the female valve stem 11, and the other end is connected to the female valve head 12. The female valve head 12 is tubular, and a second limiting member 14 is arranged on the outer wall of the female valve head 12. The second limiting member 14 is located at one end of the female valve head 12 connected to the second reset member 13, and the second limiting member 14 selectively abuts against the first abutting surface 5. The female valve stem 11 is composed of an abutting end 15 and a cut-off end 16. The abutting end 15 and the cut-off end 16 are connected by a connecting rod 17. The connecting rod 17 is on the same central axis as the first groove, and the diameter of the connecting rod 17 is smaller than the inner diameter of the female valve head 12. The outer diameter of the cut-off end 16 is adapted to the inner diameter of the female valve head 12, so that the female valve head 12 can be sleeved outside the cut-off end 16 and the two can slide relative to each other. At least one second annular groove is arranged on the outer wall of the cut-off end 16, and a second sealing member 18 is arranged in the second annular groove to increase the sealing performance between the cut-off end 16 and the female valve head 12. The end face of the abutting end 15 close to the cut-off end 16 abuts against the second reset member 13, and the other end abuts against the inner end face of the first groove. The two ends of the second reset member 13 do not need to be fixedly connected. It only needs to make one end of the second reset member 13 abut against the end face of the abutting end 15, and the other end abut against the end of the female valve head 12 and is always in a compressed stress state. Under the action of the second reset member 13, the second limiting member 14 of the female valve head 12 can be abutted against the first abutting surface 5, and at the same time, the abutting end 15 is abutted against the second abutting surface. The abutting end 15 can transmit the acting force to the cut-off end 16 through the connecting rod 17, so that the cut-off end 16 and the female valve head 12 can receive opposite acting forces through the second reset member 13. In order to ensure the liquid flow, a circulation hole is arranged on the abutting end 15, and the circulation hole is communicated with the communication hole.

[0042] When using the present utility model to connect with the mating male head body 3, first press the pressing member 7, so that the first reset member 8 is stressed until the first limiting member 9 abuts against the key positioning pin 10. At this time, the connecting hole and the second groove are on the same central axis. Then insert the male head body 3 into the second groove until the second inclined surface 31 abuts against the first inclined surface 4. Release the hand, and the pressing member 7 resets. At the same time, the connecting hole and the second groove are no longer on the same central axis, so that the pressing member 7 can be engaged with the engaging member on the male head body 3, completing the fixation between the male head body 3 and the female head body 1. During the movement of the male head body 3 in the second groove, the end of the male head body 3 abuts against the female head valve head 12, and the cut-off end 16 of the female head valve stem 11 abuts against the end of the male head valve stem. With the continuous insertion of the male head body 3, the female head valve stem 11 will not move under the action of the abutting end 15, while the cut-off end 16 will push the male head valve stem into the male head body 3, so that the male head body 3 is released from the sealed state. At the same time, the end of the male head body 3 will move towards the direction of the first groove, further pushing the female head valve head 12 to separate from the cut-off end 16, so that the female head body 1 is released from the sealed state. Thus, the male head body 3 and the female head body 1 are communicated. The male head body 3 continues to move into the first groove until the second inclined surface 31 abuts against the first inclined surface 4, completing the connection, fixation and communication between the male head body 3 and the female head body 1.
