AI Technical Summary

Technical Problem

During the movement of the sealing cover, the existing isophthalicyl isocyanate storage device leads to uneven pressure of the sealing strip, which easily causes permanent deformation of the sealing strip and affects the sealing effect.

Method used

A isophthalicyl isocyanate storage device is designed. By providing sealing strips, adsorption strips, spherical protrusions and strip-like grooves, when the sealing plug is tilted to one side, the spherical protrusions and strip-like grooves are used to disperse local pressure to avoid uneven pressure from the sealing strips and the adsorption strips.

Benefits of technology

It effectively avoids the problem of uneven force and permanent deformation after being pressed, ensuring the stability and safety of the sealing effect, and extending the service life of the device.

Abstract

The invention discloses an m-xylylene isocyanate storage device which comprises a storage device, the top end of the storage device is detachably sleeved with a sealing plug, a circle of sealing strip adheres to the side face of the sealing plug, adsorption strips are integrally formed on the upper side and the lower side of the sealing strip, and an annular notch is formed between the two adsorption strips. The connecting corners of the two adsorption strips and the sealing strip are fixedly connected with spherical protrusions, and strip-shaped grooves are formed in the spherical protrusions at equal intervals in the circumferential direction. By arranging the sealing strip, the adsorption strip, the spherical protrusions and the strip-shaped grooves, when the sealing plug is pulled out by inclining towards one side in an inclined posture, contraction deformation can be conducted through the spherical protrusions at the corners of the adsorption strip and the sealing strip, so that local pressure caused by inclined pulling-out is dispersed and conducted to the adsorption strip and the whole sealing strip; the problems that the local sealing strip and the adsorption strip are stressed unevenly and deform permanently after being pressed are effectively avoided, and the safety of m-xylylene dimethyl isocyanate stored in a laboratory for a long time is ensured.
