Embodiment
Below in conjunction with accompanying drawing, the present invention is carried out detailed description.
A kind of damper; The dampener body 1 (referring to Fig. 1,2) that comprises hollow tube-shape; The built-in major axis 2 of one end of dampener body 1 (referring to Fig. 3); Major axis 2 is the hollow tube-shape structure of end sealing, and the closed end outer wall is provided with major axis fixed position 201, the other end of major axis 2 hollows built-in with the torsion spring 3 (referring to Fig. 4) that can fix with dampener body 1.The other end of dampener body 1 is fixed with and is used to hinder the damped part 21 (referring to Fig. 5) that torsion spring rotates; Said damped part 21 comprises inside and outside two concentric axle sleeves (referring to Fig. 6); Between two axle sleeves space is arranged, the space sealing of two concentric axle sleeve one ends, the space between two axle sleeves is inserted from the other end in an axle center 4 (referring to Fig. 7); Axle center 4 can be done in the space between two axle sleeves and relatively rotated; Space between two axle sleeves also is filled with damping oil, between internal axle sleeve 5 and the axle center 4, and is provided with seal ring between axle center 4 and the external axle sleeve 6.
The concrete sealing configuration of above-mentioned axle center 4 inside and outside walls and internal axle sleeve 5 and external axle sleeve 6 is shown in Fig. 7-12; Axle center 4 is a two-stepped cylindrical body up and down; The diameter of axle center first ladder 7 on top is less than the diameter of axle center second ladder 8 of bottom; The height of the internal axle sleeve 5 of said axle sleeve is lower than the height of external axle sleeve 6, and first ladder, 7 lower edges, said axle center just in time are pressed together on the upper edge of internal axle sleeve 5, and the inwall place of axle center second ladder 8 at place, first ladder, 7 lower edges, adjacent axle center is provided with first seal ring 9 with the sealing of internal axle sleeve 5 outer walls; Said axle sleeve also is stamped axle sleeve lid 10 (referring to Figure 12); Axle sleeve lid 10 is a hollow circular ring shape lid, and axle sleeve lid 10 is pressed together on the upper edge of external axle sleeve 6 and the upper edge of axle center second ladder 8, is provided with second seal ring 11 between the upper edge of axle sleeve lid 10 and axle center second ladder 8.Above-mentioned two-stage sealing configuration can prevent damping oil leakage from the slit between axle center outer wall and the external axle sleeve inwall, also can prevent damping oil leakage from the slit between axle center inwall and the internal axle sleeve outer wall, has better leakage-preventing effect.
For the convenience of Mould Machining, said axle center second ladder 8 is spliced by two-part up and down, and said first seal ring 9 is located at second ladder upper half part inwall place, axle center.
The outer wall of said external axle sleeve 6 is provided with boss 12 (referring to Fig. 5); The inwall corresponding site of dampener body 1 is provided with the groove 13 that matches; Boss 12 snaps in (referring to Figure 13) in the groove 13, and this cooperating structure can prevent that axle sleeve and dampener body 1 from relatively rotating.
Like Figure 14, shown in 15, said damped part also is stamped minor axis 18 outward, and the bottom of minor axis 18 is provided with draw-in groove 181, and draw-in groove 181 protrudes in the part clamping that axle sleeve covers 10 tops with axle center 4, when minor axis 18 rotates, can drive the rotation in axle center.Minor axis 18 tops also are provided with fixed position 182, are used for damper is assemblied on the drive link realizing and being connected of target devices.
Shown in figure 16; Be provided with dividing plate 101 between major axis 2 in the said dampener body 1 and the damped part; Dividing plate 101 is with dampener body 1 separated into two parts; Dividing plate 101 sidewalls are provided with inserted part 13, the pintle 31 of said torsion spring 3 and the inserted part of dividing plate 101 13 cards and fixing, and this structure can prevent that torsion spring 3 and dampener body 1 from relatively rotating.
Space between said major axis 2 outer walls and the dampener body 1 scribbles damping oil.
Shown in figure 17, the sidewall of said major axis 2 one ends has the major axis scrobicular ring 14 of depression, is with the 3rd seal ring 15 with the sealing of the relevant position of dampener body 1 inwall on the major axis scrobicular ring 14.
Said major axis 2 is provided with the protruding ring 16 that a circle protrudes in major axis 2 outer walls near the other end of the dividing plate 101 of dampener body 1; The inwall of dampener body 1 and protruding ring 16 corresponding positions are provided with the depressed part 17 that cooperates with it, are provided with the 4th seal ring 18 between protruding ring 16 and the depressed part 17.
The two-stage sealing that above-mentioned the 3rd seal ring 15 and the 4th seal ring 18 have been realized major axis 2 outer walls and dampener body 1 inwall has prevented and treated damping oil and has gone out from the slot leakage of the left and right sides between major axis 2 outer walls and dampener body 1 inwall.
Scribble damping oil on major axis 2 inwalls and the torsion spring 3, can further play the effect that torsion spring rotates that hinders.
Said dampener body 1 is attaching nut's plate 20 also, the design that is formed in one of dampener body 1 and nut plate 20, and parts have been saved in this design, and make the assembling of damper more convenient.
This damper is in when assembling, needs that torsion spring 3 is turned round certain position and produces to refill behind certain torsion and be fitted in the major axis.During installation, the nut plate of damper is fixed with screw, and use drive link and target devices (inserting) to fix respectively the major axis fixed position 201 of damper major axis 2 and the minor axis fixed position 182 of minor axis 18 like lower margin.Target devices is when normal closed condition, and the torsion spring 3 in the damper has certain torsion, when target devices is opened; The torsion of torsion spring 3 discharges, and drive target devices and open fast, and in this moment damped part; Between major axis 2 outer walls and dampener body 1 inwall, and between major axis 2 inwalls and the torsion spring 3 because the damping oil of viscous is arranged, can apply reciprocal active force to torsion spring; The speed of torsion spring twisting is slowed down, thus realize target devices slowly open effect.
It is shown in figure 18 that damper of the present invention is applied to the slotting assembly structure schematic representation of lower margin; 1 is dampener body of the present invention; The major axis fixed position 201 of damper both sides and minor axis fixed position 182 fix with framework 23 (being above-mentioned drive link) both sides; Framework 23 internal fixation are equipped with functor (like switch, socket, television interface, network interface), and 24 are the slotting panel of this lower margin.
Open when the opening structure that this lower margin is inserted, functor is At time of eject under the torsion of damper torsion spring 3, and the damping oil of the inner viscous of damped part can hinder the rotation of torsion spring, thereby realizes the effect that functor slowly ejects.
The above embodiment has only expressed mode of execution of the present invention; It describes comparatively concrete and detailed; But can not therefore be interpreted as restriction to claim of the present invention; In every case adopt the technological scheme that form obtained that is equal to replacement or equivalent transformation, all should drop within protection scope of the present invention.
