[0031] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0032] Reference Figures 1 to 3The utility model provides an embodiment of a plastic steel pipe joint sealing assembly, comprising two pipes 1 and two sealing rings 12. The inner wall of the pipe 1 is fixedly connected with an inner ring 2. The outside of the two pipes 1 is detachably connected with a coupling assembly for providing pipe orifice docking. The coupling assembly includes a connecting block 3, the inner wall of the connecting block 3 is detachably connected to the rear end of the two pipes 1. The connecting block 3 can be sleeved on the groove on the surface of the pipe 1 when needed. The bottom end of the connecting block 3 is rotatably connected with a rotating shaft 4, and the outer side of the rotating shaft 4 is fixedly connected with a connecting block 2 5. The rotating shaft 4 here enables the connecting block 1 3 and the connecting block 2 5 to rotate accordingly. The front end of the connecting block 1 3 contacts the rear end of the connecting block 2 5. When the connecting block 1 3 and the connecting block 2 5 contact, the two pipes 1 are tightly clamped together. The top end of the connecting block 3 is rotatably connected with a rotating column 6. The top outside of the rotating column 6 is fixedly connected with a clamping rod 7, and the clamping rod 7 here can rotate around the rotating column 6.
[0033] The bottom end of the card rod 7 is slidably connected to the top of the connecting block 1 3, and the bottom end of the card rod 7 is slidably connected to the top of the connecting block 2 5. The front end of the inner wall of the card rod 7 is slidably connected with a card column 8. The outer bottom end of the card column 8 is in a locking relationship with the inner wall of the top of the connecting block 2 5. The card column 8 here can complete the connection of the two pipes 1 after being locked into the inner wall of the top of the connecting block 2 5. The outside of the card column 8 is fixedly connected to the limit plate 9, and the outside of the limit plate 9 is slidably connected to the inner wall of the card rod 7. The limit plate 9 here can prevent the card column 8 from accidentally detaching from the inner wall of the card rod 7. The outside of the card column 8 is provided with a spring 10, one end of the spring 10 is fixedly connected to one side of the inner wall of the card rod 7, and the other end of the spring 10 is fixedly connected to one side of the limit plate 9. The spring 10 here can provide a continuous downward force for the card column 8, so that the card column 8 and the connecting block 2 5 are locked together for a long time without falling off.
[0034] Reference Figures 4 and 5 The outer side of the sealing ring 12 contacts the inner side of the pipe 1, and the outer side of the sealing ring 12 is slidably connected to a rubber ring 13, and the outer side of the rubber ring 13 contacts the inner side of the inner ring 2. The outer side of the rubber ring 13 is fixedly connected to a plurality of plastic balls 14, and the plurality of plastic balls 14 are in a snap-fitting relationship with the inner wall of the inner ring 2. When the plastic balls 14 here are snap-fitted with the inner wall of the inner ring 2, a better seal can be provided, thereby preventing water leakage. The inner side of the rubber ring 13 is fixedly connected to a limit ring 15, and the outer side of the limit ring 15 is slidably connected to the inner wall of the sealing ring 12. The limit ring 15 here can prevent the rubber ring 13 from accidentally detaching from the inner wall of the sealing ring 12. One end of the limit ring 15 is fixedly connected to a spring 2 16, one end of which is fixedly connected to one side of the inner wall of the sealing ring 12. The spring 2 16 here provides a stable outward force for the rubber ring 13, so that it fits tightly with the inner ring 2, further improving the sealing performance of the connection of this pipe 1.
[0035] The adjacent side of the two sealing rings 12 is fixedly connected with an adhesive ring 17, and the inner wall of the adhesive ring 17 is slidably connected with a seal 18. The top of the seal 18 is fixedly connected with a handle 11. The seal 18 here is made of rubber and can be stably fixed inside the adhesive ring 17. The function of the adhesive ring 17 here is to connect the sealing rings 12 on the left and right sides together. The bottom end of the seal 18 is fixedly connected with a filter 19, and the outside of the filter 19 is slidably connected to the inner wall of the adhesive ring 17. The filter 19 here can filter out impurities in the water, thereby improving the purity of the water. At the same time, when inspecting the two pipes 1, they can be taken out and cleaned of impurities attached to them to ensure the subsequent filtration degree.
[0036] Working principle: First, place the adhesive ring 17 between the two pipes 1 together with the sealing rings 12 on the left and right sides. At this time, the multiple plastic balls 14 on the outside of the rubber ring 13 will be engaged with the inner wall of the inner ring 2, and the outside of the rubber ring 13 will also be in close contact with the inner side of the inner ring 2, thereby ensuring the sealing between the two pipes 1. The spring 2 16 here will make the connection between the two pipes 1 tighter under the action of the limit ring 15 and the sealing ring 12, further increasing the sealing between the two pipes 1. The setting of the filter 19 here enables it to filter impurities in the water, thereby ensuring the purity of the water. When a lot of impurities are attached to the filter 19, the handle 11 can be pulled to drive the seal 18 and the filter 19 to move upward, thereby removing the filter 19. At this time, the impurities on its surface can be cleaned, which is convenient for subsequent water filtration.
[0037] When two pipes 1 need to be connected, the connecting block 1 3 and the connecting block 2 5 can be put on the connection of the two pipes 1, and then the clamping column 8 is pulled first, and then the clamping rod 7 is rotated to 90 degrees of the current state, and then the hand is released. At this time, under the action of the limit plate 9, the squeezed spring 10 instantly releases the squeezing force, so that the clamping column 8 is reset, thereby completing the engagement with the top inner wall of the connecting block 2 5, and the connection between the two pipes 1 is completed. This design no longer requires the staff to carry special pipe connection tools, thereby improving the speed of pipe connection.
[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein.
