the assembly of the present invention is explained below.

As shown in fig. 1, fig. 2, fig. 4 and fig. 5, the nut 20 is firstly pressed into the two upper guide grooves 421 between the two hanging arms 42 from the through groove 44, so that the guide ribs 22 at the two sides of the nut 20 are sleeved into the upper guide grooves 421, the nut 20 falls freely under the action of the gravity of the nut 20, the nut 20 slides downwards from the upper guide grooves 421 into the lower guide grooves 422 through the guide ribs 22 until the bottom surface of the nut 20 is stopped by the bottom plate 43, and the rotation stopping installation of the nut 20 in the shaft sleeve 40 is realized; then the gasket 30 is pressed into the two upper guide grooves 421 between the through grooves 44, so that the rotating shafts 301 at the two sides of the gasket 30 are correspondingly inserted into the upper guide grooves 421 on the two hanging arms 42, and are restrained by the two rotating shafts 301 and the two upper guide grooves 421, the gasket 30 cannot rotate in the horizontal direction, after the hand is loosened, the gasket 30 freely falls under the action of self gravity, the rotating shafts 301 slide to the bottom ends of the upper guide grooves 421 along the upper guide grooves 421 and are stopped by the steps 423, because the gravity center of the gasket 30 is below the rotating shafts 301, the gasket 30 automatically swings around the rotating shafts 301 to be parallel to the axial direction of the shaft sleeve 40 and in a hanging and hanging state when hanging on the steps 423, the upper edges 311 and the lower edges 312 of the side plates 31 are parallel to the axial direction of the shaft sleeve 40, and the wedge pressing inclined surfaces 313 at the bottom ends of the side plates 31 are aligned to the corners of the nut 20 below the gasket 30, so that the nut 20 and the gasket 30 are installed on the shaft sleeve 40 in advance. Then, as shown in fig. 1, 2 and 3, 5 and 6, the bolt 10 is aligned with the insertion hole 411 in the fastening ring 41, the bolt 10 is inserted into the shaft sleeve 40 through the insertion hole 411, and the bolt 10 passes through the space 33 on the gasket 30 which is free from the space and is connected with the screw hole 21 on the nut 20 at the bottom of the shaft sleeve 40; this moment, accomplish the utility model discloses an integral assembly. The limiting plate 32 is axially parallel to the bolt 10 when the gasket 30 is in the hanging state, and the limiting plate 32 is axially perpendicular to the bolt 10 and is clamped with the nut 20 when the gasket 30 is in the hanging state, so that the overturning angle of the gasket 30 on the shaft sleeve 40 is limited to be 90 degrees.

The working principle of the present invention and the application of the present invention to the mounting and dismounting of the cover plate support on the ceramic toilet seat are explained in detail below.

As shown in fig. 11 to 13, the shaft sleeve 40 with the nut 20 and the gasket 30 is inserted downward through the mounting hole 61 of the ceramic toilet seat 60, the fastening ring 41 at the top end of the shaft sleeve 40 is inserted into the mounting hole 61, and the plurality of fins 412 fixed around the fastening ring 41 elastically deform to press the inner wall of the mounting hole 61 to fix the fastening ring 41 against rotation, so that the shaft sleeve 40 is fixedly mounted on the ceramic toilet seat 60, and the nut 20 and the gasket 30 are hung below the back of the mounting hole 61 through the shaft sleeve. The bolt 10 is then inserted into the sleeve 40 through the adjustment hole 51 of the cover bracket 50 and the insertion hole 411 of the fastening ring 41 to be coupled with the nut 20.

As shown in fig. 6, 12 and 13, the gasket 30 is hung up, and the nut 20 is located below the gasket 30, and the bolt 10 is rotated clockwise along the wedge pressing inclined plane 313 of the side plate 31 of the gasket 30 aligned above the nut 20, and the nut 20 is lifted up to the top end of the shaft sleeve 40 along the lower guide groove 422 with horizontal rotation stopping under the rotation stopping and guiding cooperation of the guiding convex rib 22 and the lower guide groove 422.

As shown in fig. 7, the angle of the rising nut 20 pushes the wedge-pressing slope 313 to lift the gasket 30, so that the rotating shaft 301 is guided by the upper guide groove 421 to rise, the rotating shaft 301 is separated from the step 423, and under the dual actions of the pushing of the angle of the nut 20 and the gravity of the heavy gasket 30, the support of the gravity center of the gasket 30 on the wedge-pressing slope 313 is unstable, so that the wedge-pressing slope 313 slides downwards along the angle of the nut 20, and the gasket 30 is rotated by the way of losing stable support of the gravity center of the gasket 30, so that the two ends of the gasket 30 swing out of the through grooves 44.

As shown in fig. 8 and 14, after the wedge-pressing inclined surface 313 slides away from the corner edge of the nut 20, the washer 30 falls back, so that the rotating shaft 301 slides down to the step 423 along the upper guide groove 421 to stably support the washer 30, and as the nut 20 continues to rise along the lower guide groove 422, the lower edge 312 of the inclined side plate 31 is pushed by the corner edge of the nut 20 by wedge pressure, so that the washer 30 continues to rotate around the step 423 as a rotation center until the washer 30 rotates 90 ° to be in a horizontal state, as shown in fig. 9 and 15, the concave clamping portion 314 on the lower edge 312 of the side plate 31 of the washer 30 is clamped on the side surface of the nut 20, so that the nut 20 is twisted on the washer 30 in the horizontal state. At this point, the gasket 30 is wedged and pressed during the upward movement of the nut 20 along the lower guide groove 422, so that the gasket 30 rotates by 90 degrees to be in a horizontal state, and the two ends of the gasket 30 are completely unfolded to expose the shaft sleeve 40.

As shown in fig. 10 and 16, as the nut 20 continuously rises along the lower guide groove 422 and enters the upper guide groove 421 through the step 423, the rotating shaft 301 of the gasket 30 is separated from the step 423 under the guidance of the upper guide groove 421, the nut 20 rises to push the gasket 30 in a horizontal state to rise together, and thus, the gasket 30 in a horizontal state can be pushed to be hooked and clamped on the back surface of the mounting hole 61 in the upward moving stroke of the nut 20 along the upper guide groove 421; the cover plate support 50 can be locked and fixed on the ceramic toilet bowl 60 by tightening the bolts 10.

As shown in fig. 10, 5 and 17, the bolt 10 is rotated reversely to make the nut 20 slide from the upper guide groove 421 to the bottom of the lower guide groove 422, the gasket 30 falls back under the self-weight and the guide of the rotating shaft 301 in the upper guide groove 421, when the rotating shaft 301 falls back to the step 423 and the nut 20 and the gasket 30 are separated in the shaft sleeve 40, the gasket 30 automatically rotates back to the hanging state under the self-weight, and the bolt 10 is pulled out of the shaft sleeve 40; the cover plate support 50 can be detached from the ceramic toilet bowl 60.

By applying the utility model, the operation can be carried out above the ceramic seat 60 of the toilet, the shaft sleeve 40 is pulled out of the mounting hole 61, and the nut 10, the gasket 30 and the shaft sleeve 40 can be taken out of the mounting hole 61; the operation can also be carried out above the ceramic toilet seat 60, and the shaft sleeve 40 is inserted into the mounting hole 61, so that the nut 10 and the gasket 30 can be preassembled below the back surface of the mounting hole 61; in addition, under the rotation stopping matching of the shaft sleeve 40 to the nut 20, the bolt 10 can be directly operated above the ceramic toilet seat 60 to be connected with the nut 20 in the shaft sleeve 40 or separated from the nut 20, and the use is very convenient.

The above embodiments are provided only for the purpose of illustration, not for the limitation of the present invention, and those skilled in the art can make various changes or modifications without departing from the spirit and scope of the present invention, therefore, all equivalent technical solutions should also belong to the scope of the present invention, and be defined by the claims.
