For the present invention in view of the above-mentioned problems, providing a kind of lead core rubber support, the bearing has good damping characteristic.
According to technical scheme：A kind of lead core rubber support, it is characterised in that：It is parallel to each other and sets including several
The rubber spacer put, backing plate is provided between two neighboring rubber spacer, the edge integrally connected of bottom rubber spacer is oriented
The rubber ring of lower extension, the inner ring of rubber ring set lower shrouding, and the top surface of lower shrouding is bonded with the bottom surface of bottom rubber spacer to be set
Put, the surface of top rubber bed course sets upper sealing plate, and cover plate is set in the upper surface endoporus of upper sealing plate；In the rubber spacer
Portion opens up filling aperture, and lead for retractable pencil is arranged in filling aperture, and lead for retractable pencil upper end is extended in the centre bore of upper sealing plate, and is resisted against cover plate
Bottom surface, the lower end of lead for retractable pencil is extended in the centre bore of lower shrouding.
As a further improvement on the present invention, the rubber spacer has six layers.
As a further improvement on the present invention, the backing plate is steel plate.
As a further improvement on the present invention, insertion offers positioning hole on the rubber spacer, positioning hole upper end with it is upper
The counterbore of shrouding bottom surface is connected, and positioning hole lower end is connected with the through hole on lower shrouding.
As a further improvement on the present invention, the length of top rubber bed course is more than the width of bottom rubber spacer, each layer
It is connected with each other between rubber spacer.
As a further improvement on the present invention, it is connected between the cover plate and upper sealing plate by screw.
The technical effects of the invention are that：Product structure advantages of simple of the present invention, changed by carrying out structure to rubber spacer
Enter so that product has excellent damping characteristic and equivalent rigidity.
