[0027] Now, the present utility model will be further described in combination with the accompanying drawings and the detailed implementation manners.

[0028] Referring to Figures 1 to 5 As shown, a rotary damper 10 provided in this embodiment includes a slow - descent rod 11, a swivel base 12, and an elastic buffer block 13. The slow - descent rod 11 has a threaded hole 111. The swivel base 12 has a screw rod 121 and an abutting cap 123 connecting the screw rod 121. Specifically, the swivel base 12 is equivalent to the structure of a bolt. The screw rod 121 of the swivel base 12 is screwed into the threaded hole 111 of the slow - descent rod 11, and the swivel base 12 rotates forward and backward relative to the slow - descent rod 11 to achieve screwing - in and screwing - out operations. The buffer block 13 is arranged between the slow - descent rod 11 and the abutting cap 123 of the swivel base 12. When the slow - descent rod 11 rotates relative to the swivel base 12 in the screwing - in direction, the distance between the slow - descent rod 11 and the abutting cap 123 gradually decreases until the buffer block 13 is squeezed. After the buffer block 13 is squeezed by the slow - descent rod 11 and the abutting cap 123, it deforms, and simultaneously exerts a damping force on the screwing - in rotation of the slow - descent rod 11 and the swivel base 12. As the degree of extrusion increases, the damping force received by the slow - descent rod 11 and the swivel base 12 becomes greater. At this time, although the screwing - in rotation of the slow - descent rod 11 and the swivel base 12 is subject to the damping force, they can still continue to rotate in the screwing - in direction within a certain range.

[0029] Continue to refer to Figures 6 to 7 As shown, this embodiment also provides a slow - descent toilet cover assembly, including a cover plate 20, a seat ring 30, a connecting shaft, and a fixed support 40; in this embodiment, the number of the connecting shafts is two, namely a first connecting shaft 1 and a second connecting shaft 2, and the cover plate 20 and the seat ring 30 are rotatably connected through two coaxial connecting shafts; wherein, both the first connecting shaft 1 and the second connecting shaft 2 are the above - mentioned rotary dampers 10. Specifically, the swivel seats 12 of the first connecting shaft 1 and the second connecting shaft 2 are both connected to the fixed support 40, the cover plate 20 and the seat ring 30 have corresponding shaft holes (the shaft hole 21 of the cover plate 20 and the shaft hole 31 of the seat ring 30 respectively), and the slow - descent rod 11 passes through the shaft hole 21 of the cover plate 20 and the shaft hole 31 of the seat ring 30 at the same time; in this way, the rotatable setting of the cover plate 20 and the seat ring 30 relative to the fixed support 40 is realized; the fixed support 40 is used to be fixed on the toilet seat.

[0030] The slow - descent rod 11 of the first connecting shaft 1 forms a circumferential limit with the cover plate 20, and the slow - descent rod 11 of the second connecting shaft 2 forms a circumferential limit with the seat ring 30. When the cover plate 20 or the seat ring 30 is turned downwards, the buffer block 13 is squeezed by the slow - descent rod 11 and the abutting cap 123, and then a damping force for turning downwards is applied to the cover plate 20 or the seat ring 30; the slow - descent function is realized. Specifically, when the cover plate 20 is turned downwards, the first connecting shaft 1 applies a damping force to the cover plate 20 to realize the slow - descent of the cover plate 20; when the seat ring 30 is turned downwards, the second connecting shaft 2 applies a damping force to the seat ring 30 to realize the slow - descent of the seat ring 30.

[0031] Set in this way, the rotary damper 10 is mainly composed of a slow - descent rod 11, a swivel seat 12, and an elastic buffer block 13. When it is applied to the slow - descent of the toilet cover assembly, it has the characteristics of simple structure, low cost, and good slow - descent effect.

[0032] Further, a perforation 131 is provided in the middle of the buffer block 13. In this embodiment, the buffer block 13 is of an annular structure, and the buffer block 13 is sleeved on the screw 121 of the swivel seat 12 through the perforation 131; in this way, the detachment of the buffer block 13 will not be caused, and when being squeezed, the extrusion force received by the buffer block 13 is uniform, and the damping force applied to the slow - descent rod 11 and the swivel seat 12 is also uniform.

[0033] More specifically, a receiving groove 112 is provided at the front end of the screw hole 111 of the slow - descent rod 11, and the buffer block 13 is received in the receiving groove 112; at the same time, this rotary damper 10 further includes a cover 14, the cover 14 is sleeved on the slow - descent rod 11, and the cover 14 abuts against the outer edge of the front end of the screw 11; when assembled into the shaft hole 31 of the seat ring 30, the cover 14 separates the front end of the screw 11 from the shaft hole 31; playing a protective role.

[0034] The above discloses a relatively preferred structure of the rotary damper 10. Of course, in other embodiments, it is not limited thereto. For example, the slow-down rod 11 may not be provided with the receiving groove 112, nor adopt the structure of the cover 14, etc.

[0035] In this embodiment, the buffer block 13 is preferably a rubber block, which has the characteristics of easy availability of materials, low cost, and good achieved effects. Of course, in other embodiments, buffer blocks 13 made of other materials such as resin and silica gel may also be used.

[0036] Further, the implementation structure of the circumferential limit between the slow-down rod 11 and the cover plate 20 or the seat ring 30 is as follows: Taking the circumferential limit cooperation between the slow-down rod 11 of the first connecting shaft 1 and the cover plate 20 as an example, the cross-section of the slow-down rod 11 is a non-circular shape. In this specific embodiment, the cross-section of the slow-down rod 11 is a polygonal shape. The shaft hole 21 of the cover plate 20 is adapted to the shape of the cross-section of the slow-down rod 11, that is, the shaft hole 21 of the cover plate 20 is a polygonal hole, while the shaft hole 31 of the seat ring 30 cooperating with the slow-down rod 11 of the first connecting shaft 1 is a circular hole; the slow-down rod 11 is sequentially inserted into the shaft hole 31 of the seat ring 30 and the shaft hole 21 of the cover plate 20, so as to form a circumferential limit with the cover plate 20, and there is no circumferential limit with the seat ring 30. Similarly, the circumferential limit cooperation between the slow-down rod 11 of the second connecting shaft 2 and the seat ring 30 is also carried out in the above manner. Among them, the cross-section of the slow-down rod 11 and the shape of the shaft hole with which it is circumferentially limited can also be non-circular shapes such as triangular, oval, "D" shape, etc.

[0037] The above circumferential limit cooperation structure enables the slow-down rod 11 to be quickly assembled and disassembled; realizing quick installation and disassembly operations. Of course, in other embodiments, other methods of assembly may also be used, such as directly setting the above detachable circumferential limit cooperation to a non-detachable fixed cooperation, etc. The fixed cooperation not only realizes the circumferential limit but also realizes the fixation in the axial direction. Its disadvantage is that it cannot be disassembled and replaced.

[0038] Further, in this embodiment, the number of the fixed supports 40 is two, corresponding to the two connecting shafts one by one. Specifically, the fixed support 40 includes a support rod 41 and a snap ring 42, and the support rod 41 is used to be fixed to the toilet seat. A fixing hole 125 is formed on the revolving seat 12, the top of the support rod 41 passes through the fixing hole 125 of the revolving seat 12, and the snap ring 42 is clamped on the top of the support rod 41 to limit the support rod 41 from detaching from the revolving seat 12. In this way, the structure of the fixed support 40 is simple, and its assembly with the revolving seat 12 is simple. By removing the snap ring 42, quick installation and disassembly operations can also be realized. The overall structure is simple and quick installation and disassembly are realized.

[0039] Further, an end cap 124 is also connected to the abutting cap 123 of the swivel base 12 on the side facing away from the screw rod 121, and the size of the end cap 124 is larger than that of the abutting cap 123; a fixing hole 125 is formed in the end cap 124.

[0040] Further, the fixing support 40 further includes a gasket 43, and the gasket 43 is assembled on the support rod 41 for padding on the surface of the toilet seat.

[0041] Of course, in other embodiments, the structure of the fixing support 40 and the connection structure with the swivel base 12 are not limited thereto. For example, the fixing support 40 is an integral support structure, and is simultaneously connected to two connecting shafts through this integral structure; the fixing support 40 and the swivel base 12 can also be fixed by means of screwing, clamping, etc.

[0042] Although the present invention has been specifically shown and described in conjunction with the preferred embodiments, those skilled in the art should understand that various changes can be made to the present invention in terms of form and details without departing from the spirit and scope of the present invention defined by the appended claims, and all of them fall within the protection scope of the present invention.
