摘要

1. A mounting plate (1) for a bag filter of a vacuum cleaner, comprising a main plate (2) with a passage hole (3), a cover (4) mounted on the main plate with a possibility of rotation to close the passage hole, and a spring element (6), which is positioned so that the angle (β) of its bending when the cover is rotated in a predetermined range of rotation angles in the opening direction (11) from the first position in which the passage hole is closed, to the second position in which the passage hole is open, is less than the corresponding angle (α) open Ia lid, wherein the lid is adapted to transfer from the second position to the first by means of the restoring force of the spring element acting against the direction of opening, and a spring element is arranged behind the cover in the direction of its opening. ! 2. A mounting plate according to claim 1, characterized in that an opening (9) is made in the lid or in the main plate, and the spring element is positioned so that one end thereof enters the hole when the lid is turned in the opening direction. ! 3. The mounting plate according to claim 2, characterized in that said hole is made through or blind. !four. A mounting plate according to claim 3, characterized in that said hole is made blind and its bottom (12) is deformed. ! 5. A fixing plate according to claim 3 or 4, characterized in that said hole is made blind, and its bottom (12) is made of an elastic material and / or film, in particular of an elastic film. ! 6. The mounting plate according to claim 1, characterized in that one end of the spring element is rigidly connected to the main plate or to the cover, and the other end is supported
