EMBODIMENT

[0029] The utility model discloses a kind of dampers, when rotating to preset angle range in two directions, it can provide damping force, realize bidirectional damping effect, meet the bidirectional damping demand of some specific occasions.

[0030] Cooperation Figures 1 to 6 As shown in the figure, a kind of damper, including shell 10 and rotating shaft 20, the shell 10 has the damping chamber 11 filled with damping oil, the rotating shaft 20 is sealed with the damping chamber 11 rotation cooperation, and the rotating shaft 20 outer wall is equipped with blade 21, the rotating shaft 20 outer wall is equipped with first matching part 22, the damping chamber 11 inner wall is equipped with second matching part 12, the rotating shaft 20 and the second matching part 12 between gap and form oil passage 13, clockwise or counterclockwise rotation rotating shaft 20, when rotating rotating shaft 20 to preset angle range, the first matching part 22 and second matching part 12 corresponding are attached, the oil passage 13 is closed.

[0031] The rotating shaft 20 extends into the damping cavity 11 at one end and is in sealing rotation with the shell 10. The vane 21 of the rotating shaft 20 is used to disturb the damping oil and is also the source of damping force. The rotating shaft 20 can rotate relative to the shell 10 to drive the vane 21 to stir the damping oil, and the damping oil flows accordingly. The slower the flow rate, the greater the resistance. There is a gap between the outer wall of the rotating shaft 20 and the inner wall of the damping cavity 11 to form an oil passage 13. When the rotating shaft 20 rotates, the vane 21 drives the damping oil to flow quickly in the entire damping cavity 11, at which time no damping force is provided. When the rotating shaft 20 rotates to a preset angle range, the first matching part 22 of the outer wall of the rotating shaft 20 corresponds to the second matching part 12 of the inner wall of the damping cavity 11, and the two are in close contact. The oil passage 13 is closed to separate the damping cavity 11 into multiple chambers. At this time, the vane 21 stirs the damping oil that cannot flow quickly to provide resistance to the rotating shaft 20.

[0032] Matching Figures 3 to 4 As shown, the inner wall of the damping cavity 11 is provided with two symmetrically arranged second matching parts 12. The outer wall of the rotating shaft 20 has two symmetrically arranged matching surfaces, and the two matching surfaces are respectively matched with the two second matching parts 12, and the two matching surfaces are respectively provided with the first matching part 22. The outer wall of the rotating shaft 20 and the inner wall of the damping cavity 11 are both center-symmetric structures. Under normal circumstances, there is a gap between the outer wall of the rotating shaft 20 and the inner wall of the damping cavity 11 to form a communicating oil passage 13. When the rotating shaft 20 rotates, the vane 21 will also disturb the damping oil, but the damping oil flows quickly through the oil passage 13, and the damper does not provide damping force. When the rotating shaft 20 rotates to a preset angle range, the first matching part 22 on the two matching surfaces respectively matches with the two second matching parts 12 to separate the damping cavity 11 into two chambers that are not communicated with each other. The oil passage 13 is closed, the vane 21 of the rotating shaft 20 disturbs the damping oil in the chamber, the damping oil cannot flow through the oil passage 13, and the damper provides resistance.

[0033] The number of vanes 21 is two and symmetrically arranged, and the two vanes 21 rotate between the two second matching parts 12. The angle of the vane 21 rotating between the two second matching parts 12 is the stroke of the rotating shaft 20. Usually, the stroke of the rotating shaft 20 is designed to be 110-120 degrees.

[0034] The first matching part 22 is a curved outer wall protruding outward from the rotating shaft 20, and the second matching part 12 is a ridge protruding radially from the inner wall of the damping cavity 11 and extending axially along the damping cavity 11. The matching surface includes a concave surface concavely arranged away from the second matching part 12 and a convex surface convexly arranged towards the second matching part 12, and the convex surface forms the first matching part 22. When the rotating shaft 20 rotates to a preset angle range, the second matching part 12 can be fitted with the convex surface, and then the oil passage 13 is closed. When the rotating shaft 20 rotates to a non-pre-set angle range, a gap is formed between the second matching part 12 and the concave surface, and then the oil passage 13 is opened. The first matching part 22 is a curved outer wall, which ensures that the first matching part 22 is always fitted with the ridge when the rotating shaft 20 rotates in the preset angle range. The central angle corresponding to the first matching part 22 is the angle range corresponding to the preset angle range, which can be set according to actual needs. The side of the second matching part 12 close to the rotating shaft 20 forms a fitting surface fitted with the first matching part 22.

[0035] Matching Figures 5 to 6 As shown, in some embodiments, the matching surface is provided with one first matching part 22, and only one first matching part 22 is fitted with the second matching part 12 when the rotating shaft 20 rotates, which corresponds to providing damping force in only one continuous preset angle range in the rotating stroke of the rotating shaft 20. Preferably, the preset angle range corresponding to the one first matching part 22 is 0-30 degrees or 60-110 degrees.

[0036] In other embodiments, the matching surface is provided with two first matching parts 22, and the two first matching parts 22 are arranged at intervals. Two first matching parts 22 are fitted with the second matching part 12 in turn when the rotating shaft 20 rotates, which corresponds to providing damping force in two continuous preset angle ranges in the rotating stroke of the rotating shaft 20. Preferably, the preset angle ranges corresponding to the two first matching parts 22 are 0-30 degrees and 60-110 degrees, respectively.

[0037] The utility model discloses still a kind of cover plates, the cover plate is installed in closestool body by above-mentioned damper, and the preset angle range is the included angle range between cover plate and horizontal plane, when opening or closing the cover plate to preset angle range, the damper provides damping force.

[0038] The cover plate is flipped to drive the rotating shaft 20 to rotate, and the cover plate is opened or closed to a preset angle range, and the damper provides a damping force to prevent the cover plate from being flipped too fast. When the preset angle range is 0-30 degrees, the damper provides a resistance to prevent the cover plate from falling too fast, and when the preset angle range is 60-110 degrees, the problem that the cover plate is easily shaken at the position is solved, and through the design of the first matching part 22 on the matching surface of the rotating shaft 20, the cover plate can be subjected to a damping action in the preset angle range of 0-30 degrees and / or 60-110 degrees.

[0039] The above is only a preferred specific embodiment of the present application, but the protection scope of the present application is not limited to this. Any person skilled in the art can easily think of changes or replacements within the technical range disclosed by the present application, which should be covered within the protection scope of the present application. Therefore, the protection scope of the present application should be subject to the protection scope of the claims.
