Utility model content

For solving the deficiencies in the prior art, the purpose of this utility model is to provide a kind of sealing effectiveness to keep for a long time and can the Glove box body used steady in a long-term.

In order to realize above-mentioned target, the utility model adopts following technical scheme:

A kind of Glove box body, comprise: metal shell and glass baffle plate, aforementioned metal shell is formed uncovered in front, glass baffle plate covers the open-mouth of metal shell, it is characterized in that, the open-mouth of aforementioned metal shell is formed with in-flanges, and the outside of aforementioned in-flanges is formed with inner seal ring groove and external seal annular groove, be formed with one between aforementioned inner seal ring groove and external seal annular groove and vacuumize hole, the aforementioned hole internal fixtion that vacuumizes has vacuum-pumping tube; Inner seal ring and exterior seal ring is separately installed with in aforementioned inner seal ring groove and external seal annular groove, foregoing glass baffle plate is pressed on inner seal ring and exterior seal ring, vacuumizes between rear glass baffle plate and inner seal ring, exterior seal ring, in-flanges and forms negative pressure of vacuum environment.

Aforesaid Glove box body, it is characterized in that, also comprise: be arranged on the fixed head around glass baffle plate, aforementioned fixed head is fitted with metal shell and is had the locking face parallel with in-flanges, aforementioned locking face is formed with screw hole, the housing screw for pressed glass baffle plate is installed in aforementioned screw hole.

Usefulness of the present utility model is:

1, Glove box body of the present utility model, negative pressure of vacuum environment is defined between its glass baffle plate and inner seal ring, exterior seal ring, in-flanges, use vacuum insulation oxygen on the one hand, effectively delay the ageing time of sealing ring, sealing effectiveness is kept for a long time, thus ensure that the long-term stability of glove box uses, air cannot enter in seal chamber on the other hand, reaches the effect of sealing, zero leakage completely.

2, around glass baffle plate, fixed head is set, by housing screw pressed glass baffle plate, further ensures the negative pressure of vacuum environment between glass baffle plate and inner seal ring, exterior seal ring, in-flanges.
