The utility model discloses a pivot falls slowly to apron, please see fig. 2 and show, with parts equipment backs such as drive screw 1, spiral guide pin bushing 2, blade 3, shell 4, with drive screw 1's other end suit in the guide pin bushing of the bottom of toilet cover plate 7, with 4 fixed suit of shells in the guide pin bushing of erection support 8, then when toilet cover plate 7 upturns or whereabouts, will drive screw 1 and rotate to it makes reciprocating motion along the axis direction of shell to drive spiral guide pin bushing 2 in the cavity of shell 4.
Referring to fig. 3, before the toilet lid 7 is completely opened, i.e. before the toilet lid 7 begins to fall, the spiral guide 2 is engaged with the bottom of the cavity of the housing 4, and the inner thread thereof is engaged with the end of the thread section of the driving screw 1, one of the second through holes of the driving screw 1 is covered by the spiral guide 2, and the end of the blade 3 with the guide groove 31 is away from the first through hole 21 of the spiral guide. With the falling of the toilet cover plate 7, the transmission screw 1 rotates and drives the spiral guide sleeve 2 to move outwards in a translational way along the axis of the cavity of the shell 4. At this time, the spiral guide sleeve 2 leaves one of the second through holes of the drive screw 1, so that the fluid medium on both sides of the spiral guide sleeve 2 flows through the two second through holes 11 of the drive screw, thereby dividing the cavity of the housing 4 into a first chamber 41 and a second chamber 42, as shown in fig. 4. In this process, since the pressure of the fluid medium in the first chamber 41 is greater than the pressure of the fluid medium in the second chamber 42, the end of the blade 3 with the guide groove 31 is pressed against the first through hole 21 of the screw guide sleeve, so that the first through hole 21 is partially covered, and therefore, the fluid medium in the first chamber 41 can only flow to the second chamber 42 through a part of the first through hole via the guide groove 31 of the blade, except through the two second through holes 21 of the drive screw. It is clear that the fluid medium in the cavity of the housing 4 flows relatively slowly in the process, i.e. the rotation speed of the drive screw 1 is relatively slow.
Referring to fig. 5, as the spiral guide sleeve 2 continues to move, the end of the blade 3 with the guide groove 31 is kept in a state of abutting against the first through hole 21 of the spiral guide sleeve. When the spiral guide sleeve 2 gradually covers the other second through hole of the drive screw 1, the rotation speed of the drive screw 1 becomes slower until finally stopping rotating. This has realized the process that the toilet lid slowly fell.
Fig. 6 is a cross-sectional view of the toilet lid of the present invention during the process of turning up the toilet lid. In the process, since the pressure of the fluid medium in the second chamber 42 is greater than the pressure of the fluid medium in the first chamber 41, the end of the blade 3 with the guide groove 31 is kept away from the first through hole 21 of the spiral guide sleeve by the pressure of the fluid medium in the second chamber 42, so that the fluid medium in the first chamber 41 and the second chamber 42 can always completely flow through the first through hole 21, and when the spiral guide sleeve 2 does not cover any second through hole of the drive screw 1, the fluid medium in the first chamber 41 and the second chamber 42 can also flow through the two second through holes 11 of the drive screw 1, so that in the process, the fluid medium in the cavity of the housing 4 flows faster, that is, the rotation speed of the drive screw 1 is faster. This realizes the process that the toilet lid is easily opened.
The above embodiments are only used to further illustrate the slow-falling rotating shaft of the present invention, but the present invention is not limited to the embodiments, and any simple modification, equivalent change and modification of the technical entity of the present invention to the above embodiments all fall into the protection scope of the technical solution of the present invention.
