Detailed Description
The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the drawings in the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts all belong to the protection scope of the present invention.
The utility model discloses in:
referring to fig. 1-3, a lock ring type safe quick-opening blind plate comprises a cylinder short section 1 and a flange cover 101, wherein the flange cover 101 is arranged inside the cylinder short section 1 in a matched manner, and a pressing mechanism is arranged on the cylinder short section 1.
Referring to fig. 1 and 2, further, the sliding rails 2 are fixedly arranged on two sides of the cylinder short section 1, the end portions of the two sliding rails 2 are rotatably provided with connecting plates 201 through rotating shafts, the connecting plates 201 are connected with the flange cover 101, rotating arms 202 are fixedly arranged between the connecting plates 201, when the flange cover 101 is closed, a worker pulls the rotating arms 202, the flange cover 101 is pulled out outwards along the sliding rails 2 for a certain distance, then the angle of the flange cover 101 is adjusted, and then the flange cover 101 is pushed into the cylinder short section 1 through the sliding rails 2.
Referring to fig. 1-3, further, the hold-down mechanism includes: movable plate 3, threaded rod 301, press plate 302 and handle 303.
Referring to fig. 1-3, further, the other side of the barrel short section 1 is provided with a movable plate 3 through rotation of a rotating shaft, one side of the movable plate 3 is movably provided with a threaded rod 301, one end of the threaded rod 301 is rotatably provided with a pressing plate 302, the other end of the threaded rod 301 is fixedly provided with a handle 303, the movable plate 3 is rotated to the center of the flange cover 101 along the rotating shaft, and then the handle 303 is manually rotated by a worker, so that the threaded rod 301 drives the pressing plate 302 to move forward to abut against the surface of the flange cover 101, and then the handle 303 is manually rotated, and when the threaded rod 301 drives the pressing plate 302 to move forward, the flange cover 101 is pushed in, so that the barrel short section 1 and the flange cover 101 are in close contact and fit.
