[0002] The lock ring type quick opening blind plate is a special pipe connection method, which is mainly used to prevent pipe leakage and pollution of the working area. The lock ring type quick opening blind plate also has the characteristics of compact structure, which not only saves space, but also has strong bearing capacity, which can meet various working conditions and ensure the safety and stability of production.

[0003] When you need to close the lock ring type quick opening blind plate, you need to thoroughly clean the dirt on the blind plate sealing surface and the sealing groove, and apply anti-rust grease, then push the blind plate end cover to make it completely embedded in the lock ring, then install the safety card plate to achieve the limit fixation of the blind plate end cover, and finally tighten the vent valve;

[0004] In the process of closing the lock ring type quick-opening blind plate, when the blind plate end cover is completely embedded in the interior of the lock ring, there is a certain gap between the blind plate end cover and the lock ring, which will reduce the sealing performance of the lock ring type quick-opening blind plate. Some lock ring type quick-opening blind plates are provided with rubber pads on the outside of the blind plate end cover. After the blind plate end cover is completely embedded in the interior of the lock ring, the operator applies pressure to the blind plate end cover through external equipment to make the rubber pad fit tightly against the lock ring, thereby reducing the gap between the blind plate end cover and the lock ring. Finally, the card plate is installed to limit and fix the blind plate end cover. Although this method improves the sealing performance of the lock ring type quick-opening blind plate, the operation is cumbersome and reduces the work efficiency. For this reason, we propose a lock ring type quick-opening blind plate. Utility Model Content

[0028] The working principle of a locking ring type quick-opening blind plate provided by the utility model is as follows: before use, the ring body 1 is first connected to the corresponding pipe, so as to realize the installation and fixation of the ring body 1 and the internal equipment. When the locking ring type quick-opening blind plate needs to be closed, the operator pushes the blind plate end cover 5 to rotate the blind plate end cover 5 around the connecting rod 3. When the blind plate end cover 5 enters the interior of the ring body 1, the baffle plate 9 is pulled forward, and the baffle plate 9 drives the plug column 8 to move forward, so that the plug column 8 is separated from the socket, and the spring 10 is extended. Then the operator drives the installation by adjusting the rotating wheel 12 The rod 66 rotates, and the mounting rod 66 drives the top plate 67 to rotate. During the rotation of the top plate 67, the connecting plate 62 receives the thrust of the top plate 67 and starts to drive the trapezoidal block 63 to move toward the end away from the inner center of the ring body 1, and the reset spring 65 contracts. When the trapezoidal block 63 is inserted into the inside of the slot 64, the trapezoidal block 63 continues to drive the blind plate end cover 5 to rotate along the inclined surface inside the slot 64, so that the rubber pad 13 is tightly attached to the inner wall of the ring body 1, and then the baffle 9 is released. The tension generated by the contraction of the spring 10 drives the plug post 8 to move and reset through the baffle 9, so that The plug post 8 is reconnected with one of the sockets provided in the middle of the outer arc surface of the chuck 7, so as to lock and fix the trapezoidal block 63, and the lock ring type quick-opening blind plate can be closed. When the lock ring type quick-opening blind plate needs to be opened, the baffle plate 9 is pulled forward, and the baffle plate 9 drives the plug post 8 to move forward, so that the plug post 8 is separated from the socket, and the spring 10 is extended. Then the operator drives the installation rod 66 to rotate by adjusting the rotating wheel 12, and the installation rod 66 drives the top plate 67 to rotate. During the rotation of the top plate 67, the contact point between the connecting plate 62 and the top plate 67 gradually moves from the distal end to the central end. The center of gravity changes. At this time, the thrust generated by the extension of the reset spring 65 drives the trapezoidal block 63 to move and reset through the connecting plate 62, thereby separating the trapezoidal block 63 from the slot 64, and then loosens the baffle 9. The tension generated by the contraction of the spring 10 drives the plug post 8 to move and reset through the baffle 9, so that the plug post 8 is re-plugged into one of the sockets set in the middle of the outer arc surface of the chuck 7, thereby locking and fixing the trapezoidal block 63. Finally, the operator pulls the blind plate end cover 5 to rotate the blind plate end cover 5 around the connecting rod 3, and the lock ring type quick-opening blind plate can be opened.
