[0022] Example 1

[0023] See also Figures 1-4The utility model provides a technical solution: a highly efficient and sealed hydraulic pipe connector, comprising: a connecting main pipe 5, the connecting main pipe 5 is configured as an upper connecting pipe 11 and a lower connecting pipe 14, the upper connecting pipe 11 and the lower connecting pipe 14 are connected together as a main pipe, but the structures of the two parts are quite different, the inner surface of the upper connecting pipe 11 is connected to a pipe head 2, the pipe head 2 is provided with a special connecting element, the pipe head 2 is connected to a hydraulic pipe 1, the hydraulic pipe 1 is tightly used to connect with other external equipment, the hydraulic pipe 1 and the pipe head 2 are As a whole, a downward pressure component 7 is provided in the upper connecting pipe 11. The downward pressure component 7 is used to open the sealing component 8 after the pipeline is installed. A sealing component 8 is provided in the lower connecting pipe 14. When the catheter is not connected, the sealing component 8 will block the first through hole 15 between the upper connecting pipe 11 and the lower connecting pipe 14, so that the internal and external liquids will no longer circulate. A first through hole 15 is provided between the upper connecting pipe 11 and the lower connecting pipe 14, and an arc surface 16 is provided on the top of the lower connecting pipe 14. The arc surface 16 is provided for better sealing.

[0024] In actual use, the pipe head 2 can only be placed in the upper connecting pipe 11 by pressing the annular slider 3 downward. When it is released and locked, liquid can flow into the main pipe after pressing down. If the pipe is not connected, no liquid will flow out of the connecting main pipe 5.

[0025] Example 2

[0026] See also Figures 1-4On the basis of embodiment 1, the down-pressing assembly 7 includes a support wheel 24, a down-pressing protrusion block and a third spring 23. The support wheel 24 is slidably connected to the inner wall of the upper connecting tube 11. The sliding of the support wheel 24 will drive the third spring 23 and the lower protrusion block 25 to move. The down-pressing protrusion block and the third spring 23 are fixedly connected to the lower surface of the support wheel 24. The support wheel 24 is arranged below a plurality of balls 10. The blocking assembly 8 includes an upper protrusion block 22, a sealing block 21, a support column 20, a down-pressing ring 17 and a second spring 19. The down-pressing ring 17 is fixedly mounted on the inner wall of the lower connecting tube 14 and fixedly connected thereto. The down-pressing ring 17 can support all pressure from above it. The support column 20 is slidably connected to the upper surface of the down-pressing ring 17. The support column 20 can penetrate the down-pressing ring The center of the ring 17, the sealing block 21 is fixedly mounted on the upper surface of the support column 20, and the upper surface of the sealing block 21 is also set to an arc shape to ensure that it is compatible with the top of the lower connecting tube 14, so that it can fit tightly and improve the sealing performance. The upper raised block 22 is fixedly mounted on the upper surface of the sealing block 21, and the upper raised block 22 plays a major force-bearing role. The second spring 19 is sleeved on the support column 20 and slidably connected thereto. When the upper raised block 22 is subjected to force, the sealing block 21 will be pressed down, and the sealing block 21 will drive the spring and the support column 20 to be pressed down. The sealing block 21 is no longer in contact with the upper surface of the lower connecting tube 14, and liquid will flow between the two when they are separated. Second through holes 18 are evenly opened on the sealing component 8, and the setting of the second through holes 18 is also to prevent obstruction of liquid circulation.

[0027] During actual use, the sealing component 8 will normally block the first through hole 15 between the upper connecting tube 11 and the lower connecting tube 14, and the upper protrusion block 22 will penetrate the through hole and extend into the upper connecting tube 11. When the pipeline is installed, the head of the pipeline will contact the support wheel 24 and press the support wheel 24 downward. The support wheel 24 will compress the third spring 23 and press down so that the lower protrusion block 25 fits with the upper protrusion block 22, and press the upper protrusion block 22 back into the lower connecting tube 14. At this time, the sealing block 21 will also move downward until the through hole can no longer be sealed, so that the liquid at both ends can convect with each other.

[0028] Example 3

[0029] See also Figures 1-4On the basis of the second embodiment, the outer wall of the upper connecting tube 11 is sleeved with an annular slider 3 and an annular plate 4. The annular plate 4 is installed at the bottom of the outer wall of the upper connecting tube 11 and is fixedly connected to the upper connecting tube 11. The outer wall of the annular plate 4 is slidably connected to the inner wall of the annular slider 3. The inner wall of the annular slider 3 is provided with a second annular groove 9 and an annular slide 13. The second annular groove 9 is to release the ball 10 so that it is no longer tightly pressed in the side wall of the upper connecting tube 11. A raised wall is provided between the second annular groove 9 and the annular slide 13. The raised wall is to better install the first spring 12. The first spring is provided in the annular slide 13. Spring 12, the first spring 12 is slidably connected to the outer wall of the upper connecting tube 11, and the top of the first spring 12 is fixedly connected to the top wall of the annular slide 13. The first spring 12 is provided to allow the annular slider 3 to be lifted up at any time so that it presses the ball 10 to extend into the first annular groove 6, so that the pipeline can be fixedly connected to the main pipe 5. A plurality of balls 10 are embedded in the outer side of the upper connecting tube 11. The plurality of balls 10 will be embedded in the side wall of the upper connecting tube 11 under normal circumstances, and will roll into the second annular groove 9 when the ring 17-shaped slider 3 is pressed down. The balls 10 cannot roll freely in the second annular groove 9 and are still restricted by the side wall of the upper connecting tube 11.

[0030] In actual use, when the pipeline needs to be installed, the annular slider 3 needs to be pushed downward by hand first. After the annular slider 3 is pushed, the ball 10 will enter the second annular groove 9, and then the pipeline head 2 will be inserted into the upper connecting pipe 11. During insertion, the support wheel 24 will drive the third spring 23 to press down, and the lower raised block 25 will press down the upper raised block 22 and push the sealing block 21 away from the top of the lower connecting pipe 14, so that it cannot play a sealing role. At this time, liquid flows. When inserted to a certain depth, the ball 10 will extend into the first annular groove 6. When the annular slider 3 is released, the pipeline head 2 will be stuck, so that the internal high-pressure liquid can flow.

[0031] Although the embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations may be made to these embodiments without departing from the principles and spirit of the present invention, and the scope of the present invention is defined by the appended claims and their equivalents.
