Background technique
Fluid viscous damper is a kind of damper commonly used, is characterized in simple in structure, absorbs that energy is many, good buffer effect.But when long-term work, its Sealing can produce wearing and tearing, the problem such as aging, thereby causes the leakage of hydraulic oil, is unfavorable for the normal operation of damper.
Summary of the invention
The purpose of this utility model is to overcome above-mentioned deficiency, thereby a kind of damper is provided, and adopts new sealing configuration, improves the reliability of sealing, realizes the zero leakage of damper when long-term work.
The technological scheme provided according to the utility model, damper comprises hydraulic cylinder, it is characterized in that: be provided with piston plate in hydraulic cylinder, the hydraulic cylinder upper end is by the first bolted flange lid.Piston plate is threaded connection piston rod, and blind flange is stretched out in the piston rod upper end.The piston plate upper end connects gland by the second bolt, clamps an end of elastic packing interlayer between gland and piston plate, and the other end of elastic packing interlayer clamps by hydraulic cylinder and blind flange.The piston plate lower end connects damping plate by the 3rd bolt, and the damping plate lower plane flushes with the piston plate lower plane.Piston plate is provided with the first damping hole, and damping plate is provided with the second damping hole, and the first damping hole is communicated with the second damping hole.
Further, be provided with gap between piston plate and hydraulic cylinder sidewall.
Further, be provided with the 2nd O RunddichtringO between hydraulic cylinder and blind flange.
Further, the piston rod upper end is threaded connection mounting plate.
Further, be provided with an O RunddichtringO between gland and piston rod.
Further, the blind flange upper end connects rubber plate.
Compared with the prior art the utility model has the following advantages:
The utility model is simple in structure, compact, reasonable, good reliability; Adopt new sealing configuration, improve the reliability of sealing, realize the zero leakage of damper when long-term work; Except playing seal action, a resiliently deformable compensation space also is provided simultaneously, without other design space collocation structure, make overall structure obtain optimization; Damper can automatically be adjusted damping in the to-and-fro motion process, prevents from being evacuated.

Embodiment
Following the utility model is further described in connection with the embodiment in accompanying drawing:
As shown in Figure 1, the utility model mainly comprises hydraulic cylinder 10, is provided with piston plate 8 in hydraulic cylinder 10, between piston plate 8 and hydraulic cylinder 10 sidewalls, is provided with certain gap.Hydraulic cylinder 10 upper ends, by the first bolt 5 adpting flange lids 4, are provided with the 2nd O RunddichtringO 12, the sealing guaranteed between hydraulic cylinder 10 and blind flange 4 by the 2nd O RunddichtringO 12 between hydraulic cylinder 10 and blind flange 4.
Piston plate 8 is threaded connection piston rod 2, and blind flange 4 is stretched out in piston rod 2 upper ends, and piston rod 2 upper ends are threaded connection mounting plate 1.
Piston plate 8 upper ends connect gland 6 by the second bolt 13, clamp an end of elastic packing interlayer 7 between gland 6 and piston plate 8, and the other end of elastic packing interlayer 7 clamps by hydraulic cylinder 10 and blind flange 4.Described elastic packing interlayer 7 adopts rubber material to make, and has certain extensibility, can leak by sealed hydraulic cylinder body 10 interior hydraulic oil.
Piston plate 8 lower ends connect damping plate 9 by the 3rd bolt 14, and damping plate 9 lower planes flush with piston plate 8 lower planes.Piston plate 8 is provided with the first damping hole 15, and damping plate 9 is provided with the second damping hole 16, the first damping holes 15 and is communicated with the second damping hole 16.
Be provided with an O RunddichtringO 11 between described gland 6 and piston rod 2, the sealing guaranteed between gland 6 and piston rod 2 by an O RunddichtringO 11.
Described blind flange 4 upper ends connect rubber plate 3, and rubber plate 3 plays buffer function.
Working principle of the present utility model is: when the utility model is subject to extraneous percussion, piston rod 2 and piston plate 8 can move downward along hydraulic cylinder 10, at this moment the hydraulic oil pressurized of oil hydraulic cylinder 10 middle and lower parts can up flow by the second damping hole 16 on damping plate 9, produce larger frictional damping, extraneous impact kinetic energy is converted into to frictional heat energy, reduce the ballistic motion response, thereby formed good cushioning effect.When piston rod 2 and piston plate 8 up move while resetting, the hydraulic oil pressurized on hydraulic cylinder 10 tops is toward current downflow, now, damping plate 9 separates with piston plate 8, and hydraulic oil the first damping hole 15 on piston plate 8 of flowing through, enter the second damping hole 16 and flow downward, now, formed damping force can be smaller, can prevent from being evacuated, and the normal stable operation of assurance device.
