Detailed description of the invention

Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.

See accompanying drawing 1,2 and accompanying drawing 4, in the utility model specific embodiment one, a kind of buffer hinge for toilet lid, comprises housing 1, hinge core shaft 2.Its middle shell 1 comprises the locating hole 12 of enclosure interior front end, enclosure interior chamber wall is provided with the chamber fragmenting plate 10,11 of two opposition, housing cavity is divided into the first chamber 13 and the second chamber 14 by chamber fragmenting plate 10,11, wherein, chamber fragmenting plate 11 and the preferred integrated structure of housing 1.

As shown in Figure 2, hinge core shaft 2 comprises the connecting axle 21 connecting outside toilet lid, is arranged at the buffer shaft 22 in housing 1 and locating shaft 23, and wherein locating shaft 23 is positioned at buffer shaft 22 front end face.For strengthening the sealing between housing 1 and hinge core shaft 2, seal groove 24 being set in hinge core shaft 2 connecting axle 21 and contact position, housing 1 rear end, in seal groove 24, rubber seal 241 being installed.

In the utility model specific embodiment one, the buffer shaft 22 of hinge core shaft 2 is symmetrically arranged with two buffering floors 221,222, wherein the first buffering floor 221 is arranged in the first chamber 13, second buffering floor 222 and is positioned at the second chamber 14.In the utility model specific embodiment two buffering floor 221,222 respectively spoiler 25,26 dismountable with two coordinates, with to the damping fluid in housing 1 chamber enter buffering obstruction.

Housing as shown in Figure 1, the end at aperture self sealss groove 24 place of housing 1 internal chamber reduces gradually to end, locating hole 12 place.Hinge core shaft 2 as shown in Figure 2, buffer shaft 22 also self sealss groove 24 place to the section radius of the other end reduces gradually, and the aperture of its middle shell 1 internal chamber is identical with the slope of buffer shaft 22, makes buffer shaft 22 just be arranged on housing 1 thus inner.

In the utility model specific embodiment one, the aperture of housing 1 internal chamber and buffer shaft 22 have broken the thinking that conventional buffer hinge middle shell internal chamber is cylindrical and hinge core shaft section radius is identical, but make both all have certain slope, when toilet lid being declined or rises, side's squeezing flow that can be little to aperture after damping fluid near the chamber that aperture is large is squeezed, increases the cushion effect that buffer hinge mandrel is horizontal and longitudinal.

Buffer hinge in the utility model specific embodiment one is adapted to the buffer hinge in specific embodiment two.As shown in Figure 3 in the utility model specific embodiment two, face the structure of buffer shaft 22, spoiler 25,26 entirety surrounds a side of buffering floor 221,222, buffering floor another side is not surround completely, but leaves the duct 27 that damping fluid passes through.When buffer shaft 2 surpasses different directions rotation, damping fluid act on power on buffering floor 221,222 and direction different, thus make damping fluid different by the speed in gap between spoiler 25,26 from buffering floor 221,22, namely the cushion effect of buffer hinge is different.

In the utility model specific embodiment two, the operation principle of buffer hinge for toilet lid is: when toilet lid declines, in buffer hinge, the rotation direction of buffer shaft 2 as shown in Figure 4, wherein in the first chamber 13, spoiler 25 in buffer shaft 2 extrudes the damping fluid of bottom, and damping fluid applies power upwards to spoiler 25, makes to block with tighter between buffering floor 221 and spoiler 25, gap smaller between them, damping fluid is slow by the speed of spoiler 25; The extruding and the chamber little towards aperture one side flows by damping fluid simultaneously, increase the stressed of spoiler again again, make the gap between buffering floor 221 and spoiler 25 less, damping fluid is slow further by the speed of spoiler 25, thus makes toilet lid decrease speed more and more slower.Wherein in another chamber 14, buffering floor is identical with the cushioning principle of spoiler, is not repeated herein.

On the contrary, when toilet lid is mentioned, just the opposite shown in the rotation direction of buffer shaft 2 and Fig. 4 in buffer hinge, now, in the first chamber 13, buffering floor 221 upwardly damping fluid, damping fluid applies pressure to buffering floor and spoiler 25 simultaneously, and due to spoiler 25 not complete engaging buffering floor 221 in the one side of buffering floor 221 pressurized, make damping fluid pass through the duct 27 cushioned on floor 221 and impact spoiler, and the gap between spoiler 25 and buffering floor 221 is increased, thus relatively increase the speed of damping fluid by spoiler 25; Simultaneously in aperture compared with the damping fluid of little housing 1 chamber location because the damping fluid pressure produced in toilet lid decline process is large, therefore, now damping fluid can be expressed to larger chamber location place, aperture, damping fluid is increased further by the speed of spoiler 25, thus the speed opening toilet lid is improved.The cushioning principle being arranged in the buffering floor 222 of the second chamber 14 and spoiler 26 is identical with the first chamber, does not also repeat at this.

In the utility model body embodiment two, each buffering floor 221,222 includes several several L along buffer shaft 22 arranged radially and inverted L shape dividing plate 3, spoiler 25,26 is an overall structure and can engages with dividing plate 3, and the top droop angle of the entirety after dividing plate 3 coordinates with spoiler 25,26 is identical with buffer shaft 22 angle of inclination; Wherein, there is the gap that damping fluid flows in dividing plate 3 bottom spoiler 25,26 after coordinating with spoiler 25,26.

In the utility model specific embodiment two, dividing plate 3 and buffer shaft 22 are formed in one structure.Certainly, housing 1 and the chamber fragmenting plate 10,11 of enclosure interior also can be formed in one structure.To improve production efficiency and the packaging efficiency of buffer hinge.

In the utility model specific embodiment two, spoiler 25,26 is integrally moulded structure, to reduce the wearing and tearing of spoiler 25,26 and easily to install, reduces production cost and improves production efficiency.

Obviously, in the utility model specific embodiment two, connecting axle 21 connects toilet lid (depending on going out), and the link 15 of the other end of housing can connect toilet seat (depending on going out), wherein link 15 is with internal thread, obviously also can be other connected modes.Certainly, according to actual demand, connecting axle 21 can connect toilet seat, and housing 1 link 15 can connect toilet lid, to make toilet seat and the equal available buffer landing of toilet lid.Hinge core shaft 2 in the utility model specific embodiment can directly be assembled with metal shell 1 and coordinate cushioning effect, such that buffer hinge finished weight is light, parts are few, and production cost detail declines.

Further, in the utility model specific embodiment two, housing 1 is provided with the joint 17 connecting toilet seat, to reduce the parts of buffer hinge, can be directly fixed in toilet seat by the shell 1 with hinge core shaft 2.Wherein, joint 17 can be the female joint of band, and other modes and toilet seat also can be selected to fix.Thus avoid hinge core shaft and must coordinate lining, lining fixedly mounts the tedious steps of metal shell and multiple parts again.

Use technical solutions of the utility model, damping fluid can be made slowly to flow between two chambers separated by chamber fragmenting plate 11, be in damping fluid under sealing condition owing to being in the motion of extruding always, the damping fluid being in the large position of buffer shaft section radius can extrude to the direction that buffer shaft section radius is little, thereby increase damping fluid resistance, thus add cushion effect.

The foregoing is only preferred embodiment of the present utility model; not in order to limit the utility model; all within spirit of the present utility model and principle, any amendment done, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
