Description

Technical Field

[0001] The utility model relates to the technical field of filters, in particular to a sealing plug for a discharge box. Background Art

[0002] The discharge port of the two-in-one / three-in-one filter will be equipped with a discharge device to control the opening and closing of the filter discharge. The opening and closing of the filter discharge is mainly controlled by the hydraulic cylinder to push the plug.

[0003] According to a disclosed filter discharge device (publication number: CN213064618U), an annular groove is provided on the surface where the plug abuts against the filter discharge pipe in the above application, and an O-ring is installed in the annular groove. By adopting the O-ring seal instead of the ordinary plane seal, the sealing effect is better. The hinge structure and the bolt structure cooperate to form a quick-opening structure, which can quickly and conveniently open the back cover, making it convenient for the staff to open the back cover to clean the inside of the cylinder.

[0004] In actual use, the O-ring on the plug should be replaced in time after its service life is reached to avoid affecting the sealing effect of the plug. The O-ring of the device is installed inside the annular groove. When the O-ring needs to be replaced, the O-ring needs to be picked out. The O-ring is usually made of rubber. When the O-ring fits tightly with the annular groove, the O-ring lacks a fulcrum and is difficult to pick out. Replacement is very troublesome. Utility Model Content

[0027] The ejection mechanism 7 comprises a rotating block 71, a sliding rod 72, a guide rod 73, a cam block 74, an ejection rod 75, and a limit spring 76; the rotating block 71 is rotatably connected to the outer wall of the connecting block 4, and the cam block 74 is fixedly installed on the outer wall of the rotating block 71. The rotating block 71 drives the cam block 74 to rotate synchronously, and the cam block 74 squeezes the guide rod 73. The sliding rod 72 is slidably connected to the inner wall of the slide groove 5. One end of the sliding rod 72 is fixedly installed with an ejection rod 75, and the other end of the sliding rod 72 is fixedly installed with a limit spring 76. The sliding rod 72 cooperates with the ejection rod 75. The sealing ring 3 inside the groove 2 can be pushed outward so that the sealing ring 3 protrudes from the groove 2, which is convenient for picking out the sealing ring 3 and replacing it. The end of the limit spring 76 away from the slide rod 72 is fixedly installed on the inner wall of the slide groove 5, and the guide rod 73 is fixedly installed on the side wall of the slide rod 72. The outer wall of the guide rod 73 fits the outer wall of the cam block 74.
