[0032] The present invention is further described below in conjunction with the accompanying drawings and specific implementation methods. It should be noted that, under the premise of no conflict, the various embodiments or technical features described below can be arbitrarily combined to form a new embodiment.

[0033] Embodiment 1:

[0034] Please combine Figure 1-6 , a quick-open blind plate switch auxiliary device of this embodiment includes a plate body 1, a cleaning mechanism is provided on the plate body 1, and the cleaning mechanism includes a cleaning rod 4, a limit unit and a pressing replacement unit;

[0035] The limiting unit includes a fixing buckle 2, a storage buckle 3 and a clamping unit. The fixing buckle 2 and the storage buckle 3 are both fixed on the plate body 1, and the cleaning rod 4 can pass through the fixing buckle 2 and enter the storage buckle 3 to be limited by the clamping unit;

[0036] The press-to-replace unit includes two rotating rods 6, a driving slot 7, a cleaning cloth 8, a connecting block 19, a sponge 20, a linkage unit and a driving unit. The driving slot 7 is opened in the cleaning rod 4, both ends of one of the rotating rods 6 are fixed in the cleaning rod 4 through bearings, and both ends of the other rotating rod 6 are fixed in the driving slot 7 through bearings. The two rotating rods 6 are driven and connected by the linkage unit, both ends of the connecting block 19 are provided with a driving unit, and the sponge 20 is fixed at one end of the connecting block 19, and both ends of the cleaning cloth 8 are respectively fixed on the rotating rod 6, and the middle part of the cleaning cloth 8 is in contact with the sponge 20 and is located outside the cleaning rod 4.

[0037] If the sponge 20 does not have engine oil, the sponge 20 can be used for a long time only by dripping engine oil on it.

[0038] The clamping unit comprises an arc groove 5 , two arc grooves 5 are both formed on the cleaning rod 4 , and a semicircular block is fixed inside the storage buckle 3 , and the arc groove 5 can be clamped in the semicircular block.

[0039] The implementation principle of a quick-opening blind plate switch auxiliary device in the present application is: first, the pipe connected to one side of the plate body 1 is depressurized, and then the handle on one side of the plate body 1 is held and unlocked with a wrench, so that the plate body 1 and the connecting pipe on the rear side can be separated, so that the sealing surface and the machined surface are exposed.

[0040] When it is necessary to clean the sealing surface and the machined surface, the cleaning rod 4 is pulled away from the storage buckle 3, so that the cleaning rod 4 slides in the fixed buckle 2 and gradually separates from the storage buckle 3. At the same time, the arc groove 5 gradually separates from the semicircular block inside the storage buckle 3. After the cleaning rod 4 is completely separated from the fixed buckle 2, the cleaning rod 4 is held, and one end of the cleaning cloth 8 is used to contact the sealing surface and the machined surface and move for cleaning. Because the sponge 20 contains a certain amount of engine oil, when the cleaning cloth 8 is used to clean it, the sponge 20 will be slightly compressed and deformed. Therefore, the engine oil in the sponge 20 will penetrate into the cleaning cloth 8 that is in contact with the sponge 20. After cleaning it, the U rod 21 is pressed into the movable groove 23 to compress the spring 24 to make The card block 22 is away from the card slot provided on the movable slot 23. When the U rod 21 moves into the movable slot 23, the two movable rods 15 are pulled to move into the cleaning rod 4, so that the slider 14 slides on the slide rail 13, so that the hinge block 17 contacts the gear 12. As the movable rod 15 goes deeper into the cleaning rod 4, the hinge block 17 rotates so that one end of it contacts the fixed plate 16, stretching the spring 18. Then, when the movable rod 15 continues to go deeper into the cleaning rod 4, the gear 12 is driven to rotate. When the movable rod 15 goes deeper into the cleaning rod 4, the sponge 20 is away from the cleaning cloth 8, so that the cleaning cloth 8 cannot be in a taut state. The rotation of the gear 12 drives the driving rod 11 to rotate counterclockwise, and then the linkage leather Under the connection of belt 2 10, the rotating rod 6 connected to the linkage belt 2 10 is driven to rotate counterclockwise, and the rotating rod 6 is also rotated counterclockwise. Under the linkage of linkage belt 1 9, the other rotating rod 6 not connected to the linkage belt 2 10 is also rotated counterclockwise, so that the rotating rod 6 connected to the linkage belt 2 10 releases the cleaning cloth 8, and the rotating rod 6 not connected to the linkage belt 2 10 wraps around the cleaning cloth 8, and then drives the cleaning cloth 8 on one side of the sponge 20 to be replaced. At this time, when the U rod 21 can no longer be pressed, the U rod 21 is released, and the rebound of the spring 24 drives the card block 22 to be re-carded in the card slots on both sides of the movable slot 23, and at the same time drives the moving rod 15 to move outward of the cleaning rod 4 The hinge block 17 moves along with the moving rod 15 to move outside the cleaning rod 4. When the hinge block 17 passes through the gear 12, the spring 18 will be compressed, and the hinge block 17 will be horizontal, moving out of the gap between the gear 12 and the moving rod 15, and will not drive the gear 12 to rotate. The moving rod 15 also drives the sponge 20 back to its original position, so that the sponge 20 pushes out the cleaning cloth 8 again, and then the cleaning cloth 8 is in a taut state again, completing the alternating work of the cleaning cloth 8, and then the cleaning rod 4 is passed through the fixed buckle 2, driving the cleaning cloth 8 to enter the storage buckle 3, so that the semicircular block inside the storage buckle 3 is again stuck on the arc groove 5, limiting the cleaning rod 4, thereby completing the cleaning work, and then the plate body 1 can be closed again.
