Description
Technical field
It the utility model is related to light curtain protector vibration absorber technical field, more specifically a kind of seal isolation formula light
Curtain vibration-proof structure.
Background technology
Light curtain protector is a kind of security classes product, is often employed in above forging equipment, but because forging equipment exists
It is larger using process vibrations, it is easy to infringement is produced to light curtain, influences light curtain service life so that light curtain protector is except to electricity
Have in terms of gas outside special requirement, special requirement is there has also been for inner structural members.
Most domestic light curtain protector internal circuit board uses rigid connection with light curtain shell at present, does not buffer,
It is easy to damage the component of circuit board in vibration environment, breaks down.
The content of the invention
To solve the above problems, overcome the deficiencies in the prior art, the utility model provides a kind of seal isolation formula light curtain
Vibration-proof structure, the anti-seismic performance of light curtain is improved, add light curtain service life, and simple in construction be easily assembled to and safeguard.
To achieve the above object, seal isolation formula light curtain vibration-proof structure provided by the utility model, including：Packing ring, screw
Hole I, T-shaped boss, pad, skeleton, fixed plate, neck, rectangular boss, shell body, screw hole II；It is characterized in that the packing ring
Inner side sets T-shaped boss, and the T-shaped boss is connected in a snap-fit manner with neck, and rectangular boss is set on the outside of the packing ring, described
Rectangular boss is fixedly connected with shell body, and the screw hole I on the packing ring is connected with the screw hole II on shell body in a manner of screw
Connect, the fixed plate is provided with the protruding parts that pad is located in pad, and the skeleton bottom is fixedly connected with fixed plate.
Further, the gasket thickness is 2-3mm.
Further, the gasket materials are NBR rubber.
Further, the screw hole I is semi-closed form, and aperture is less than mounting screw diameter.
The beneficial effects of the utility model are：The utility model seals off formula light curtain vibration-proof structure, can solve light curtain
Protector is due to vibrating the injury to light curtain, while and can carries out IP protection as sealing gasket to light curtain inside, and gasket materials are adopted
It is process with NBR rubber, preferable with good screen resilience, decay resistance, washer has rectangle boss, with shell
Body extruding connection, for vibration reduction and cushioning, screw hole semi-closure conjunction state so that attachment screw using when can reach better seal
Effect.
