The specific embodiment
Clearer for technical problem, technical scheme and beneficial effect that the utility model is solved, below in conjunction with accompanying drawing and embodiment, the utility model is further elaborated.Should be appreciated that specific embodiment described herein only in order to explanation the utility model, and be not used in qualification the utility model.
Like Fig. 1 to shown in Figure 5, the damping unit that the utility model embodiment provides comprise damping cover 1, with said damping cover 1 in relative rotation axis of rotation 3, be socketed in the sealing ring 2 on the said axis of rotation 3 and seal the damping sealing plate 4 of said damping cover 1.
As shown in Figure 3, damping cover 1 is cylindric, the one of which end opening, and other end bottom is provided with a columniform boss 13, and the centre of said boss 13 is provided with air vent 14.As preferred version, said air vent 14 is the screw thread air vent, and the screw thread air vent helps the processing of air vent itself, and helps the assembling of damping unit.Said damping is overlapped 1 inner side and is arranged at intervals with first boss 11 and second boss 12; Said first boss 11 is provided with first oilhole 111 that runs through first boss 11; Said second boss 12 is provided with second oilhole 121 that runs through second boss 12, and the aperture of said first oilhole 111 is greater than the aperture of second oilhole 121; Said first boss 11 and second boss 12 form chamber with said damping cover 1, and said chamber interior is filled with damping oil.
To shown in Figure 8, the longitudinal section of said first oilhole 111 is an arc like Fig. 6.The longitudinal section of said second oilhole 121 is an arc.The longitudinal section of first oilhole 111 and second oilhole 121 is the processing that arc helps oilhole.Be appreciated that on said first boss 11 a plurality of oilholes can be set, or that damping oil is flowed is rapider in the aperture that increases oilhole, so that more laborsaving when damping unit is opened.Quantity and pore size that oilhole can be set on said second boss 12 are regulated the damping of damping unit in closing closed procedure.The shape of cross section in the hole of said first oilhole 111 and second oilhole 121 can be different shapes such as circle, square, rectangle, triangle, helps processing as long as satisfy.As preferred version, said first oilhole 111 is circular for cross section, and said second oilhole 121 is circular for cross section, and cross section is the circular processing that can make things convenient for the hole on the one hand, on the other hand, is convenient to flowing of damping oil.Present embodiment with first oilhole 111 and second oilhole 121 be separately positioned on first boss 11 with second boss 12 on, in the use of reality, oilhole can not be worn, and therefore can increase the service life, and damping is unaffected.
Like Fig. 4 and shown in Figure 8, the longitudinal end of axis of rotation 3 is provided with alar part 311, and said alar part 311 is in the said chamber through said first boss 11 spacing and with said chamber separation with second boss 12.Form the first chamber A between said first boss 11 and the said alar part 311, form the second chamber B between said alar part 311 and said second boss 12, form the 3rd cavity C between said first boss 11 and said second boss 12.Said alar part 311 is the fan annular, and said first boss 11 and second boss 12 are the fan annular that adapts with alar part 311 shapes, and the consistency of thickness of the thickness of said alar part 311 and said first boss 11 and second boss 12 is to form the hermetic cavity chamber.Said axis of rotation 3 comprise successively connect have the axle connecting portion 31 of alar part 311, the middle part 32 that is provided with seal groove 321 and a department of assembly 33, the axle center of said axle connecting portion 31 is provided with and is used for the locating hole 312 of position rotating axle 3.Said locating hole 312 and said boss 13 location, and around said boss 13 rotations.The external surface of said department of assembly 33 is provided with fitting recess 331.Said fitting recess 331 is the grooving that in department of assembly 33, is provided with, and the frictional force that it can increase department of assembly 33 and external member makes it after assembling, be not easy to rotate.
Said sealing ring 2 is assemblied in the seal groove 321 of said axis of rotation 3 and axis of rotation 3 fuses.The applying of 1 inner tight is overlapped in its lateral surface and said damping, plays sealing function.
As shown in Figure 5, damping sealing plate 4 is provided with sealing 41, and the centre of damping sealing plate 4 has the department of assembly 33 that a circular assembling through hole 42 is convenient to axis of rotation 3 and passes, and sealing 41 matches with axis of rotation 3 and makes damping oil be sealed in damping to overlap 1 inside.
Fig. 6 is extremely shown in Figure 8 to be the motion process of the damping unit of present embodiment.
Opening procedure: as shown in Figure 6, the damping unit that present embodiment provides is in closed condition, and this moment, the alar part 311 of said axis of rotation 3 fit together with said second boss 12; This moment, the space of the first chamber A was maximum; The space of the second chamber B is minimum, and when needs were opened damping unit, the department of assembly 33 of said axis of rotation 3 linked to each other with external member and the power through external member is rotated axis of rotation 3 in damping cover 1; Said axis of rotation 3 rotations drive said alar part 311 to 11 motions of first boss; This moment, state was as shown in Figure 7, because alar part 311 makes damping oil flow through to first oilhole 111 of first boss 11, and the aperture of first oilhole 111 is greater than the aperture of second oilhole 121; Therefore required drive is less, and damping unit is opened lighter.When alar part 311 moves to first boss, 11 places, and when fitting with said first boss 11, this moment, damping unit was opened fully, and the space of the first chamber A is minimum, and the space of the second chamber B is maximum, and this moment, state was as shown in Figure 8.
Close closed procedure: when needs are closed damping unit; The department of assembly 33 of said axis of rotation 3 links to each other with external member and the power through external member makes axis of rotation 3 rotation in damping cover 1; Said axis of rotation 3 rotations drive said alar part 311 to 12 motions of second boss, because alar part 311 makes damping oil flow through to second oilhole 121 of second boss 12, and the aperture of second oilhole 121 is less than the aperture of first oilhole 111; Therefore required drive is bigger, and damping unit is opened has buffering effect.
The damping unit that the utility model provides, required drive is little when opening, and be easy to open, and required power is big when closing, and damping is provided, thereby slows down the impact force of the product of installing, and then prolongs the application life of the product of installing.
More than be merely the preferred embodiment of the utility model, be in order to help to understand the spirit and the main points of this patent, but be not the protection domain that is used to limit the utility model.All within the spirit and principle of the utility model, any modification of being done, be equal to replacement, improvement etc., all should be included within the protection domain of the utility model.
