The technical solution adopted in the utility model is: described damping isolator mainly comprises: base is fixed with drain pan at the periphery of base; Be characterized in: on base, also be fixed with cylinder barrel, spherical flange is connected the bulb of slip fork on the base, the center fixed of top cover has the disjunctor piston, the lower end of disjunctor piston extend in the cylinder barrel, and the periphery of top cover is fixed with inner barrel, and the top of top cover is placed with vibration isolator, support plate is arranged on the vibration isolator top, the center fixed of support plate has guide rod, and guide rod is movably arranged in the disjunctor piston after passing vibration isolator, and the upper end of slip fork is connected with guide rod after passing disjunctor piston and guide rod; Pressure spring is arranged between top cover and the base; Between support plate and drain pan, also be provided with protecting cover.
The further technological scheme of the utility model is: also be provided with air outlet hole interior on simplified.
The utility model further technological scheme is: the downside at top cover also is fixed with guide pin bushing, and guide pin bushing is arranged in pressure spring.
The utility model another further technological scheme be: protecting cover is tightly connected with support plate and drain pan respectively.
The utility model has the advantages that: described vibration isolator is simple in structure, and vibration isolating effect is remarkable, less expensive.
Description of drawings
Fig. 1 is a kind of embodiment's of a damping isolator described in the utility model structural representation;
The structural representation of header field among Fig. 2 Fig. 1;
Fig. 3 is the structural representation of support plate part among Fig. 1.
Mode of execution
Below in conjunction with the drawings and specific embodiments technological scheme described in the utility model and working principle thereof and advantage are further described.
As Fig. 1, Fig. 2, shown in Figure 3, damping isolator described in the utility model mainly comprises: base 19 is fixed with drain pan 15 at the periphery of base 19; Be characterized in: on base 19, also be fixed with cylinder barrel 14, spherical flange 18 is connected the bulb 17 of slip fork 13 on the base 19, the center fixed of top cover 4 has disjunctor piston 1, the lower end of disjunctor piston 1 extend in the cylinder barrel 14, the periphery of top cover 4 is fixed with interior simplified 12, in the present embodiment, on inner barrel 12, also be provided with air outlet hole 11; The top of top cover 4 is placed with rubber vibration insulating pad 6, support plate 5 is arranged on rubber vibration insulating pad 6 tops, the center fixed of support plate 5 has guide rod 7, guide rod 7 is movably arranged in the hole of disjunctor piston 1 after passing rubber vibration insulating pad 6, after disjunctor piston 1 and guide rod 7 are passed in the upper end of slip fork 13, slip fork 13 is connected with guide rod 7 with bolt 8; Pressure spring 2 is arranged between top cover 4 and the base 19; Between support plate 5 and drain pan 15, also be provided with protecting cover 3, in the present embodiment, the downside of support plate 5 is fixed with guard ring 9, one end of protecting cover 3 is installed on the guard ring 9, the other end of protecting cover 3 is installed on the drain pan 15, and be tightly connected respectively between protecting cover 3 and guard ring 9 and the drain pan 15, protecting cover 3 can be made with flexible materials such as rubber.In addition, in the present embodiment, also be fixed with guide pin bushing 10 at the downside of top cover 4, guide pin bushing 10 is arranged in pressure spring 2, and guide pin bushing 10 has location and leading role.
The working principle of the damping isolator of said structure is: before use, can inject liquid-state silicon oil damping cream 16 in advance in drain pan 15 and cylinder barrel 14.Then damping isolator is placed on required place.
When damping isolator receives when vibration, support plate 5 transfers vibrations on the rubber vibration insulating pad 6, at first be rubber vibration insulating pad 6 distortion and with the energy of hysteresis form consumption vibration, produce damping simultaneously again vibration be absorbed; Transfer vibrations on the pressure spring 2 by top cover 4 again then, pressure spring 2 also produces distortion and the energy that vibrates with the consumption of hysteresis form, the while produces damping again is absorbed for the second time vibration; Above-mentioned rubber vibration insulating pad 6 and the structure that pressure spring 2 is used can be isolated dither effectively.When rubber vibration insulating pad 6 is shaken distortion, guide rod 7 can move in the hole in the disjunctor piston 1, because the seal action of rubber vibration insulating pad 6, air in this hole in the disjunctor piston 1 is sealed, thereby guide rod 7 is when mobile, and the air in this hole is compressed formed resistance and has become additional damping again.When pressure spring 2 is shaken when moving down, top cover 4 and disjunctor piston 1, and in simplified 12 move down along slip fork 13 together because the viscosity of liquid-state silicon oil damping cream 16 is very big, also be that its damping is very big, thereby move extremely slowly, can absorb vibration effectively; And, when disjunctor piston 1 and inner barrel 12 moved down, the air in interior simplified 12 can be passed into from air outlet hole 11 in the drain pan 15, form new vapor liquid equilibrium with the liquid-state silicon oil damping cream 16 that overflows from cylinder barrel 14, damping is increased, improved shock attenuation result.Slip fork 13 makes parts such as support plate 5 and top cover 4 to swing in certain angle by the bulb 17 and the structure that base 19 is connected of its lower end, can improve shock attenuation result equally.
From the above mentioned as can be known, above-mentioned vibration isolator is simple in structure, and vibration isolating effect is remarkable, less expensive.
