Abstract
The utility model discloses a kind of adjustable shock absorber, its structure comprises vibration damper cabinet mounting plate, steel rope damper, vibration damper compensation guide plate, mounting screw, wherein steel rope damper one side is connected to vibration damper cabinet mounting plate by mounting screw, and another side also connects vibration damper by mounting screw and compensates guide plate.The utility model device layout is reasonable, vibrating isolation system can be realized bearing under safe impact condition by the characteristic of variation rigidity, mutative damp and possess good adjustment vibration isolation function, avoid network cabinet depth direction have unstability to be inclined to or occur tilting in relative movement, swing angle is excessive, cause network cabinet center of gravity sharply to offset theoretical value, thus the overflow fixed load causing design to select cause the situation of defective shock absorber.
Description
Technical field
The utility model relates to computer vibration damper technical field, is specifically related to a kind of adjustable shock absorber.
Background technique
Along with the development of modern military technology, more and more higher to the requirement of the anti-vibration and shock of the electronics such as airborne, vehicle-mounted, carrier-borne, machinery, not only require that single devices vibration damping is reinforced and also require that the network cabinet integral vibration damping of placement devices is reinforced.Network cabinet restricts by factors such as weight and height, usually adopts bottom and back to fix vibration damper coupling and makes for carrying out buffer shock-absorbing.Bottom vibration absorber adopts steel rope damper usually, and this model vibration damper can bear resiliently deformable, multidirectional anti-vibration and shock on any degrees of freedom direction, space.Back vibration damper effect is balance inertial force, inertia distance and horizontal impact power, improves stability during rack motion.In vehicle-mounted field operations transport, airbornely to climb etc. in harsher environment, network cabinet depth direction have unstability to be inclined to or occur tilting in relative movement, swing angle is excessive, network cabinet center of gravity can be caused sharply to offset theoretical value, and the overflow fixed load causing design to select causes defective shock absorber.
Summary of the invention
The technical problems to be solved in the utility model is: design a kind of rigidity and the adjustable vibration damper of damping for these problems; current vibration damper damping member can be made to lose efficacy; the problem of equipment unprotect device is resolved, the final normal use ensureing the equipment such as network cabinet.
The technological scheme that the utility model adopts is:
A kind of adjustable shock absorber, its structure comprises vibration damper cabinet mounting plate, steel rope damper, vibration damper compensation guide plate, mounting screw, wherein steel rope damper one side is connected to vibration damper cabinet mounting plate by mounting screw, another side also connects vibration damper by mounting screw and compensates guide plate, by compensating the effect of guide plate, when by External Force Acting, vibration damper can be realized and on any degrees of freedom direction, bear resiliently deformable, multidirectional anti-vibration and shock.
Described vibration damper compensates on guide plate and is provided with chute, and vibration damper adjusting slider is arranged at vibration damper by chute and compensates guide plate.When external shock, vibration damper adjusting slider can compensate guide plate slides along vibration damper, realize the non-linear hysteresis damping of dry friction, ensure that vibrating isolation system is bearing under maximum safe impact condition, compensate resiliently deformable by adjustment and make equipment possess good anti-vibration performance.
Described steel rope damper is 2 that are arranged side by side, and is arranged between vibration damper cabinet mounting plate and vibration damper compensation guide plate.When being subject to the external impacts of either direction, compensating guide plate by the vibration damper connecting two steel rope dampers, external force can be distributed to two steel rope dampers simultaneously, increase damping effect further, strengthening the stability of equipment.
The beneficial effects of the utility model are: the utility model device layout is reasonable, vibrating isolation system can be realized bearing under safe impact condition by the characteristic of variation rigidity, mutative damp and possess good adjustment vibration isolation function, avoid network cabinet depth direction have unstability to be inclined to or occur tilting in relative movement, swing angle is excessive, cause network cabinet center of gravity sharply to offset theoretical value, thus the overflow fixed load causing design to select cause the situation of defective shock absorber.
