DETAILED DESCRIPTION

[0021] like Figure 1-Figure 6 As shown, a quick-connect valve includes a quick-connect male connector 7 connected to a storage container 1 and a quick-connect female connector 4 connected to a receiving container 5. The cross-sections of the quick-connect female connector 4 and the quick-connect male connector 7 are both set to be U-shaped. The quick-connect male connector 7 can move in the vertical direction relative to the storage container 1. Figure 3 As shown, a through groove 702 is provided on the bottom surface of the quick-plug male connector 7, and a first sealing ball 9 is provided at the through groove 702. The first sealing ball 9 can move in the vertical direction relative to the quick-plug male connector 7. The through groove 702 can be sealed by the first sealing ball 9, so as to prevent the raw materials in the storage container 1 from leaking out. A push rod 11 is installed at the inner bottom end of the quick-plug female connector 4. When actually used, the receiving container 5 is pushed to one side of the storage container 1, so that the quick-plug female connector 4 and the quick-plug male connector 7 are in a coaxial state in the vertical direction. When the raw materials in the storage container 1 fill the quick-plug male connector 7, the quick-plug male connector 7 can be driven to move downward, thereby prompting the quick-plug male connector 7 to be inserted into the quick-plug female connector 4. During this process, the first sealing ball 9 in the quick-plug male connector 7 can be pushed upward by the push rod 11, so that the first sealing ball 9 is away from the through groove 702. At this time, the raw materials in the storage container 1 can flow into the quick-plug female connector 4 through the quick-plug male connector 7, and then flow into the receiving container 5 through the quick-plug female connector 4, thereby completing the use of the materials in the storage container 1.

[0022] Further, in order to improve the sealing performance between the quick-plug male connector 7 and the quick-plug female connector 4, in actual application, a plurality of annular grooves 402 are provided on the inner wall of the quick-plug female connector 4, and a sealing ring 15 is embedded in each of the plurality of grooves 402. Figure 3As shown, a second chamfer 16 is provided at the inner edge of the top end of the quick-plug female connector 4 and the outer edge of the bottom end of the quick-plug male connector 7. Through this structure, when the quick-plug male connector 7 is inserted into the quick-plug female connector 4, the second chamfer 16 on the quick-plug male connector 7 will squeeze the sealing ring 15, so that the sealing ring 15 can be smoothly located at the outer peripheral wall of the quick-plug male connector 7, thereby sealing the gap between the quick-plug male connector 7 and the quick-plug female connector 4.

[0023] To sum up, during the use of this device, when the raw materials fill the quick-plug male head 7, the quick-plug male head 7 can be inserted into the quick-plug female head 4 and sealed therewith, and the through groove 702 can be opened by cooperating with the first sealing ball 9 through the provided push rod 11. At this time, the raw materials in the storage container 1 can be transported to the receiving container 5 through the quick-plug male head 7 and the quick-plug female head 4, so that the raw materials can be taken. When the material taking is completed, the raw materials can be stopped from being replenished in the quick-plug male head 7. At this time, the quick-plug male head 7 will move upward and gradually away from the quick-plug female head 4. During this process, the first sealing ball 9 will return to the through groove 702 and seal the through groove 702, and the receiving container 5 can also be removed. This device is easy to operate and has good stability.

[0024] like Figure 1-Figure 6 , Figure 9-10 As shown, during the frequent material taking process, the quick-insertion male head 7 will contact and rub against the sealing ring 15 many times. Therefore, the sealing ring 15 needs to be replaced after being used for a period of time. In order to make reasonable use of multiple sealing rings 15, in this solution, a rod sleeve 14 is sleeved on the outer side of the top rod 11, and the bottom end of the top rod 11 passes through the rod sleeve 14 and is fixedly provided with a turntable 12. The top rod 11 and the rod sleeve 14 are matched by a clamping assembly, and the first sealing ball 9 and the top rod 11 are matched by a limiting assembly. In actual use, when the quick-insertion male head 7 moves downward at a faster speed, When the push rod 11 is driven to rotate by the limiting assembly, the push rod 11 can drive the turntable 12 at its bottom end to rotate synchronously. Under the action of centrifugal force, the clamping assembly can be disengaged from the rod sleeve 14 during the rotation of the turntable 12, so that the push rod 11 can move downward relative to the rod sleeve 14. At this time, the quick-plug male connector 7 needs to move downward a long distance, and the push rod 11 can push the first sealing ball 9 upward. Therefore, the outer peripheral wall of the quick-plug male connector 7 can cover more sealing rings 15, thereby improving the sealing between the quick-plug male connector 7 and the quick-plug female connector 4.

[0025] The above-mentioned clamping assembly includes a clamping block 19 which is arranged on the outer peripheral wall of the push rod 11 and elastically cooperates with the push rod 11. The inner wall of the rod sleeve 14 is provided with an annular clamping groove 24. In the initial state, the clamping block 19 is in a pop-up state and inserted into the clamping groove 24, so that the push rod 11 can be locked in the vertical direction. Furthermore, a counterweight block 17 is slidably provided on the outer peripheral wall of the rotating disk 12 , and a pull rope 18 is fixedly provided between the counterweight block 17 and the clamping block 19 , and the pull rope 18 passes through the counterweight block 17 and the top rod 11 and slidably cooperates with the both.

[0026] The outer side of the rod sleeve 14 is provided with a base 13, the cross section of the base 13 is an inverted U shape, and the bottom end of the rod sleeve 14 passes downward through the base 13 and is fixedly connected to the base 13. The above-mentioned turntable 12 is located in the inner cavity of the base 13, and the base 13 is fixedly installed on the bottom surface of the inner cavity of the quick-plug female connector 4.

[0027] The limiting assembly includes a limiting block 20 elastically matched with the first sealing ball 9. Specifically, a socket 10 is provided on the outer wall of the first sealing ball 9. When the quick-plug male connector 7 is aligned with the quick-plug female connector 4, the socket 10 and the push rod 11 are in a coaxial arrangement. The limiting block 20 is arranged at the inner wall of the socket 10. Figure 5 As shown, the top of the limit block 20 and one side close to the top rod 11 is provided with an inclined surface 2001, and the outer peripheral surface of the top rod 11 is provided with a spiral limit groove 1102. Fig. 9 As shown, a first chamfer 1101 is provided at the top end and the outer edge of the push rod 11. Through this structure, when the limit block 20 is inserted into the limit groove 1102 and moves downward relative to the push rod 11, the cooperation between the limit block 20 and the limit groove 1102 can drive the push rod 11 and the turntable 12 to rotate.

[0028] In actual use, when the storage container 1 has sufficient raw materials, the raw materials exert a greater pressure on the quick-plug male connector 7 after filling the quick-plug male connector 7, thereby driving the quick-plug male connector 7 to move downward at a faster speed and insert into the quick-plug female connector 4. In the process of the quick-plug male connector 7 inserting into the quick-plug female connector 4, the top end of the push rod 11 will also be inserted into the socket 10 on the first sealing ball 9. By setting the first chamfer 1101, the limit block 20 can move downward through the first chamfer 1101. When the limit block 20 coincides with the limit groove 1102 on the outer wall of the push rod 11, the limit block 20 can pop out and be inserted into the limit groove 1102. As the quick-connect male connector 7 continues to move downward, the limit block 20 and the limit groove 1102 can drive the push rod 11 and the turntable 12 to rotate. At this time, the counterweight 17 on the turntable 12 can be thrown out under the action of centrifugal force. During the process, the block 19 can be pulled by the pull rope 18 so that one end of the block 19 can be moved out of the slot 24. After the block 19 is disengaged from the slot 24, the push rod 11 will move downward together with the first sealing ball 9. When the turntable 12 contacts the bottom surface of the inner cavity of the quick-plug female connector 4, it stops moving. At this time, as the quick-plug male connector 7 drives the first sealing ball 9 to continue to move downward, the push rod 11 will contact the inner top wall of the socket 10 and push up the first sealing ball 9 so that the first sealing ball 9 is far away. When the through groove 702 is opened, the raw materials in the storage container 1 can flow into the receiving container 5 through the quick-plug male connector 7 and the quick-plug female connector 4. Since the quick-plug male connector 7 moves downward a long distance relative to the quick-plug female connector 4, the quick-plug male connector 7 can cover more sealing rings 15. Therefore, even if there are a lot of raw materials in the storage container 1 and the pressure on the quick-plug male connector 7 is relatively large, the sealing between the quick-plug male connector 7 and the quick-plug female connector 4 can be ensured by multiple sealing rings 15. When there is less raw material in the storage container 1, the raw material will fill the quick-plug male connector 7 and exert less pressure on the quick-plug male connector 7, so that the quick-plug male connector 7 moves downward more slowly. Therefore, after the top end of the push rod 11 is inserted into the inside of the socket 10, the rotation speed of the turntable 12 driven by the cooperation of the limit block 20 and the limit groove 1102 is not enough to throw out the counterweight 17, so that the clamping block 19 and the clamping groove 24 are in a stable cooperation state. In this state, the push rod 11 will not move downward relative to the rod sleeve 14, and when the quick-plug male connector 7 covers the first sealing ring 15 and continues to move downward, the top end of the push rod 11 will contact the top wall of the inner cavity of the socket 10 and drive the first sealing ball 9 to move upward, so that the raw material in the storage container 1 can flow into the receiving container 5. Since the raw material in the storage container 1 exerts less pressure on the quick-plug male connector 7, the sealing between the quick-plug male connector 7 and the quick-plug female connector 4 can be ensured by fewer sealing rings 15. When the material is taken, the quick-insertion male connector 7 moves upward, and the cooperation between the limit block 20 and the limit groove 1102 can drive the push rod 11 to move upward. When the block 19 on the push rod 11 is aligned with the slot 24, the block 19 can pop out and be inserted into the slot 24, so that the push rod 11 is locked with the rod sleeve 14 in the vertical direction again. When the limit block 20 moves to the top position of the limit groove 1102, the inclined surface 2001 on the limit block 20 will contact the side of the limit groove 1102, so that the limit block 20 can be squeezed into the first sealing ball 9, so that the limit block 20 can be separated from the limit groove 1102.

[0029] To summarize, this device cooperates with the provided clamping assembly and the limiting assembly. When the quick-plug male connector 7 is subjected to greater pressure and moves downward rapidly, the quick-plug male connector 7 can cover more sealing rings 15 after being inserted into the quick-plug female connector 4, thereby ensuring the sealing between the quick-plug male connector 7 and the quick-plug female connector 4. When the raw material in the storage container 1 is less, the speed at which the quick-plug male connector 7 moves downward under pressure will be reduced, so that the quick-plug male connector 7 covers less sealing rings 15 after being inserted into the quick-plug female connector 4. Therefore, through this device, the sealing ring 15 can be reasonably utilized while ensuring the sealing effect between the quick-plug male connector 7 and the quick-plug female connector 4, thereby extending the service life of the sealing ring 15.

[0030] In order to drive the installation of the quick-plug male connector 7, the present invention provides a sleeve 3 on the outer side of the quick-plug male connector 7. Figure 1 As shown, the outer side of the sleeve 3 is provided with a support ring 2 through a bearing sleeve, and the support ring 2 is fixedly connected to the storage container 1 through a support rod, and the top of the quick-connect male connector 7 is fixedly connected with a bellows 101, and the bellows 101 is connected to the storage container 1 through a metal pipe fixed on the storage container 1, referring to Figure 3 As shown, a convex ring 701 is fixedly sleeved on the outer wall of the quick-connect male connector 7, and at least two guide rods 6 are arranged on the convex ring 701. The top ends of the guide rods 6 are fixedly connected to the storage container 1, and the bottom ends of the guide rods 6 pass downward through the convex ring 701 and slide with the convex ring 701. The convex ring 701 is located on the inner side of the sleeve 3; The inner wall of the sleeve 3 is provided with a plurality of guide grooves 301. Figure 6 As shown, the projection of the guide groove 301 on the vertical plane is roughly triangular, that is, one side of the guide groove 301 is a vertical side, and the other side of the guide groove 301 is a hypotenuse. Figure 6As shown, an annular groove 302 is provided on the inner wall of the sleeve 3 and located above the guide groove 301, so that the top ends of the multiple guide grooves 301 are connected to the annular groove 302, and the multiple guide grooves 301 are distributed on the inner wall of the sleeve 3 in an annular array, and the bottom wall of the annular groove 302 and located between two adjacent guide grooves 301 are provided with a support portion 303, and a guide column 25 is fixedly provided on the outer peripheral wall of the quick-plug male connector 7, and the end of the guide column 25 away from the quick-plug male connector 7 is inserted into the guide groove 301; In actual use, a branch pipe 401 is fixedly arranged between the quick-plug female connector 4 and the receiving container 5, and the two ends of the branch pipe 401 are respectively connected to the quick-plug female connector 4 and the receiving container 5. In actual use, ball valves can be installed on the above-mentioned metal pipe and the branch pipe 401 to control the opening and closing of the branch pipe 401 and the metal pipe. Specifically, after the material is taken out, the staff can rotate the sleeve 3, and the pressure of the bevel on the guide groove 301 on the guide column 25 can drive the quick-plug male connector 7 to move upward, so that the quick-plug male connector 7 is separated from the quick-plug female connector 4. When the guide column 25 is on the support portion 303, the quick-plug male connector 7 can remain stable relative to the storage container 1. When the material needs to be taken out, the sleeve 3 can be rotated again. When the guide column 25 is aligned with the guide groove 301, the guide column 25 can move downward along the straight edge on the guide groove 301. Therefore, when the raw material fills the quick-plug male connector 7, it can drive the quick-plug male connector 7 to move downward and insert it into the quick-plug female connector 4.

[0031] Reference Figure 3 As shown, a vertical rod is fixedly provided on the inner bottom surface of the quick-connect male connector 7, and a horizontal protrusion 8 is fixedly provided on the outer surface of the first sealing ball 9. The vertical rod passes through the protrusion 8 and slidably cooperates with the protrusion 8. A baffle is integrally formed on the top of the vertical rod, and a limit spring is provided between the baffle and the protrusion 8. The limit spring is sleeved on the outside of the vertical rod.

[0032] Reference Figure 4 As shown, the outer circumference of the push rod 11 is provided with a groove that slides with the block 19, a first spring is fixedly arranged between the inner end surface of the groove and the block 19, and the outer circumference of the turntable 12 is provided with a sliding groove that slides with the counterweight block 17.

[0033] Reference Figure 5 As shown, a mounting groove which is slidably matched with the limit block 20 is opened on the inner wall of the insertion hole 10, and a second spring is fixedly arranged between the inner end surface of the mounting groove and the limit block 20.

[0034] Reference Figure 7-Figure 8As shown, as another method for blocking the branch pipe 401, a positioning column 23 can be installed at one end of the branch pipe 401 away from the quick-plug female connector 4. Specifically, a notch matching the positioning column 23 is provided on the end surface of the branch pipe 401, so that both ends of the positioning column 23 can be engaged in the notch. In addition, a second sealing ball 21 is installed at one end of the branch pipe 401 close to the quick-plug female connector 4, and a tension spring 22 is provided between the second sealing ball 21 and the positioning column 23. In actual use, when the quick-plug male connector 7 is inserted into the quick-plug female connector 4, the bottom end of the quick-plug male connector 7 will squeeze the second sealing ball 21, thereby causing the second sealing ball 21 to deviate from the end of the branch pipe 401, so that the raw material can flow into the receiving container 5 through the branch pipe 401.

[0035] Reference Fig. 9 As shown, a straight groove 1103 connected to the limiting groove 1102 can be opened on the outer wall of the push rod 11, and the straight groove 1103 is vertical. Through this structure, when the push rod 11 lifts the first sealing ball 9, the limiting block 20 can slide along the straight groove 1103, thereby preventing the push rod 11 from rotating.

[0036] In actual use, a ball bearing may be installed on the bottom surface of the clamping block 19 to reduce the friction between the clamping block 19 and the clamping groove 24 .
