Detailed description of the invention
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
As shown in Figure 1-Figure 3, damping mechanism comprises gland 3, rotating shaft 2 and fills the housing 1 of damping oil.Sealed by O type circle 4 between gland 3 and housing 1.
As shown in Fig. 4-Fig. 8, the blade 21 of disturbance damping oil when the rotating shaft 2 of toilet seat cover plate damping mechanism is provided with rotation, housing 1 is provided with the dividing plate 11 being carried out by housing 1 inner chamber splitting.In opening procedure and closing process, the lumen segmentation of housing 1 is become high-voltage oil cavity and low pressure oil pocket by dividing plate 11.When cover plate is in open mode and closure state, blade 21 is had to rotate two side positions to dividing plate 11 respectively.As shown in Figure 4, dividing plate 11 liang of side body 1 inwalls are provided with the first gas pressure relief slot.When cover plate is in open mode, on housing 1 inwall of blade 21 correspondence is open position first gas pressure relief slot 12; When cover plate is in closure state, blade 21 corresponded closed positions first gas pressure relief slot 13.When blade 21 swings to the first corresponding gas pressure relief slot position 12,13 with rotating shaft 2, the blade 21 that script is sealed and housing 1 are at the first gas pressure relief slot place, form an oily passage of mistake, thus be communicated with high-voltage oil cavity and low pressure oil pocket, realize the abrupt release of oil pocket pressure, thus do not rebound when realizing cover plate open and close.First gas pressure relief slot of described inner walls can be formed by subtracting material or carry out in adjacent position adding material formation in this position.
In order to discharge the pressure of high-voltage oil cavity to greatest extent, coordinate with dividing plate 11 be in cover plate open and/or closure state rotating shaft 2 axial plane on the second gas pressure relief slot is set.First gas pressure relief slot and the second gas pressure relief slot can exist simultaneously, or optionally can arrange one of them as required.As shown in Figure 5, when cover plate is in open mode, on rotating shaft 2 axial plane of dividing plate 11 correspondence is open position second gas pressure relief slot 22; When cover plate is in closure state, dividing plate 11 corresponding closed condition second gas pressure relief slot 23.When rotating shaft 2 rotate coordinate to the second gas pressure relief slot position with dividing plate 11 time, the second gas pressure relief slot formed oily passage, release oil pocket pressure.Second gas pressure relief slot is the oil groove excessively of gradual change, can change oil pocket pressure gradually.Between dividing plate 11 and rotating shaft 2, being provided with gradual change crossing oily passage 24, for improving the pressure of high-voltage oil cavity when cover plate closing gradually, reaching the object of slowly landing.
The operation principle of the present embodiment is as follows:
When upwards digging cover plate, cover plate is in opening procedure, and as shown in Figure 6, rotating shaft 2 is in turning clockwise, and gradual change is crossed oily passage and become large gradually, and liquid resistance diminishes gradually, reaches the light object opening cover plate.
When cover plate opens to certain angle, when being in open mode, as shown in Figure 7, blade 21 corresponding open position first gas pressure relief slot 12, open position second gas pressure relief slot 22 simultaneously in the corresponding rotating shaft 2 of dividing plate 11, rotating shaft 2 is in being rotated counterclockwise, and the damping oil of high-voltage oil cavity flows to low pressure oil pocket by open position first gas pressure relief slot 12 on housing 1 and open position second gas pressure relief slot 22 in rotating shaft 2 instantaneously, and the pressure of high-voltage oil cavity is lower; Now high-voltage oil cavity and low pressure oil pocket communicate, and gradual change crosses that oily passage 24 is maximum, and the high pressure in oil pocket effectively reduces, and realizes opening procedure without rebounding and keeping standing.
When closing cover plate downwards, cover plate is in closing process, as shown in Figure 8.Rotating shaft 2 is in being rotated counterclockwise, when rotating shaft turns over the position of this open position first gas pressure relief slot 12 and open position second gas pressure relief slot 22, high-voltage oil cavity and low pressure oil pocket are closed, gradual change is crossed oily passage 24 and is diminished gradually, thus improve the pressure of high-voltage oil cavity gradually, to adapt to the torque demand constantly increased, reach the object that cover plate slowly lands.
When cover plate is in closure state, as shown in Figure 9, blade 21 corresponded closed positions first gas pressure relief slot 13, closed position second gas pressure relief slot 23 in the corresponding rotating shaft of dividing plate simultaneously, now high-voltage oil cavity and low pressure oil pocket communicate, it is minimum that oily passage is crossed in gradual change, the damping oil of high-voltage oil cavity flows to low pressure oil pocket by closed position first gas pressure relief slot 13 on housing 1 and closed position second gas pressure relief slot 23 in rotating shaft 2 instantaneously, enclosed high pressure oil pocket pressure is discharged by these 2 gas pressure relief slots, thus reduce the pressure of high-voltage oil cavity instantaneously, reduce cover plate bounce-back probability, realize closing process without rebounding and reaching quiet effect.
The utility model also can adopt one or more combination in open position first gas pressure relief slot 12 that is arranged on inner walls and/or closed position first gas pressure relief slot 13, open position second gas pressure relief slot 22 of rotating shaft axial plane and/or closed position second gas pressure relief slot 23, in addition, gas pressure relief slot can also be arranged on two end faces of the oil pocket that housing and rotating shaft are formed, can reach and close without bounce-back and/or the effect opening nothing bounce-back preferably, play the effect of release high-voltage oil cavity pressure, its effect is equivalent; Further, described gas pressure relief slot can be the gradual change groove extended along the circumference of rotating shaft axial plane or inner walls, or described gas pressure relief slot is the axially extended straight trough along rotating shaft axial plane or inner walls.
Although specifically show in conjunction with preferred embodiment and describe the utility model; but those skilled in the art should be understood that; not departing from the spirit and scope of the present utility model that appended claims limits; in the form and details the utility model is made a variety of changes, be protection domain of the present utility model.
