Abstract
The utility model belongs to a vibration reduction device, in particular to a sleeve type vibration reduction device which comprises a limit screw; a gasket is arranged under a cap of the limit screw; a vibration reduction pad is arranged under the gasket; and the cap of the limit screw, the gasket and the vibration reduction pad are arranged in a damper cylinder. The sleeve type vibration reduction device has the effects that a buffer device made of a rubber material is used for vibration reduction, and a fixing device made of a metal material is used for guaranteeing a circuit board to be damped to be stable, so that a good vibration reduction effect can be realized under the condition of high vibration level and wider frequency range (10-2000Hz) of vibration energy distribution.
Description
Technical field
The utility model belongs to vibration damping equipment, is specifically related to a kind of sleeve type vibration damping equipment.
Background technique
Vibration damping equipment is widely used in machinery and electronic applications.Existing vibration damping equipment is that the rubber pad by individual layer constitutes mostly; This type vibration damping equipment can only be applied in common vibration damping occasion; If it is big to run into vibration level; And (10～2000Hz) situation, common vibration damping equipment can not play due damping effect to the frequency range broad of vibrational energy distribution.
Summary of the invention
The utility model provides a kind of good damping result, the sleeve type vibration damping equipment of vibration damping wide frequency range to the defective of existing technology.
Summary of the invention: a kind of sleeve type vibration damping equipment, comprise stop screw, below the stop screw head of a nail, be provided with pad, below pad, be provided with damping pad, the stop screw head of a nail, pad and damping pad all are arranged in the damper cylinder.
The effect of the utility model is: the effect of the utility model is: utilize the damping device of rubber material to carry out vibration damping; Use the fixing device of metal material to guarantee by the shock absorption circuit plate stable simultaneously; Thereby can be implemented in the face of vibration level is big, and the frequency range broad of vibrational energy distribution (has excellent vibration damping effect during 10～2000Hz) situation.
Description of drawings
Fig. 1 is the structural representation of a kind of sleeve type vibration damping equipment of providing of the utility model;
Structural representation when Fig. 2 is the use of sleeve type vibration damping equipment.
Among the figure: 1. damper cylinder, 2. pad, 3. damping pad, 4. stop screw, 5. circuit board, 6. mounting hole, 7. power model, 8. rubber sheet gasket, 9. complete machine housing.
Embodiment
Below in conjunction with accompanying drawing the utility model is described further.
Shown in accompanying drawing 1, a kind of sleeve type vibration damping equipment comprises stop screw 4, below stop screw 4 heads of a nail, is provided with pad 2, below pad 2, is provided with damping pad 3, and stop screw 4 heads of a nail, pad 2 and damping pad 3 all are arranged in the damper cylinder 1.
The use and the installation process of the vibration damping equipment of the utility model are following: need to suppose the parts of vibration damping to comprise circuit board 5 and power model 7; This circuit board 5 all need be fixed on the complete machine housing 9 with power model 7; At first will increase rubber sheet gasket 8 this moment between complete machine housing 9 and power model 7; Guarantee mounting hole 6 alignment on circuit board 5, power model 7 and the complete machine housing 9 then; Successively be enclosed within the head of a nail place of stop screw 4 with pad 2 and damping pad 3 this moment, then damper cylinder 1 is socketed in the head of a nail place of stop screw 4 and wraps pad 2 and damping pad 3, then stop screw 4 passed mounting hole 6 and tighten.
