Description
Affiliated technical field
The utility model relates to a kind of seal arrangement, especially the transparent panel of vacuum glove box and the seal arrangement between the frame.
Background technique
Vacuum glove box (also claim " vacuum work station ") is the operating platform that is usually used in industry such as medicine, electronics and breadboard dustless or vacuum, because the operating cabin during work in the frame need vacuumize or purify air, so the sealability between its transparent panel and the frame is particularly important.At present, the transparent panel of vacuum glove box and the sealing between the frame generally are that between is provided with elastic seal ring, on the periphery of transparent panel, be equipped with some installation through holes at interval, by passing these bolts that through hole is installed transparent panel is connected with the frame merit, there is the defective of following two aspects in this sealing means, one, sealability is bad, because the power of impelling elastic seal ring distortion and being close to frame attachment face and transparent panel internal surface is to put in a mode that contacts on the outer surface of transparent panel by bolt, therefore the deformation extent of elastic seal ring distortion is inhomogeneous, inaccessible and keep excellent sealing performance, and sealing was lost efficacy easily in use for some time; They are two years old, the stress of through hole is concentrated on the transparent panel periphery, install and using process in transparent panel all easily embrittlement takes place and damage, because of beating numerous installation through holes at transparent panel, it is higher to make, assemble difficulty, and the installation or removal transparent panel is also inconvenient on frame.
The model utility content
For overcome existing vacuum glove box seal arrangement sealability relatively poor, easily lost efficacy and the fragile deficiency of transparent panel, the vacuum glove box seal arrangement that technical problem to be solved in the utility model provides a kind of good seal performance and is difficult for losing efficacy, its transparent panel is stressed evenly, all is difficult for chipping in sealing installation and using process.
The technological scheme that its technical problem that solves the utility model adopts is: seal arrangement of the present utility model, include frame, transparent panel and the elastic seal ring between the internal surface of the attachment face of frame and transparent panel, it is characterized in that: be surrounded with the press strip that is connected with described frame by link on the periphery of described transparent panel, described press strip is pressed on the periphery of described transparent panel, fits between described frame attachment face and elastic seal ring, elastic seal ring and the transparent panel internal surface to form to be tightly connected.
In seal arrangement of the present utility model, press strip all applies uniform power towards the frame attachment face to the whole periphery of transparent panel, and under the effect of this power, the elastic seal ring distortion evenly, its front and rear surfaces is close to transparent panel internal surface and frame attachment face respectively, and forms effective seal.Because transparent panel is peripheral stressed even, therefore in sealing installation and using process, all be difficult for chipping.
For simplified structure and be convenient to installation and removal, in the draw-in groove of the periphery of described transparent panel between the front screen of described press strip, the press strip rear surface relative with the attachment face of frame, the outer surface of described transparent panel contacts with described front screen.
For further improving the validity of sealing, the lower end of the front screen of described press strip is provided with flange relative with described transparent panel outer surface and that contact with it; Described press strip rear surface is provided with the attachment face flange relative and that contact with it with described frame; Have mounting hole on the described press strip, described link is the bolt that the screw section is passed mounting hole and is connected with described frame.Described and the contacted flange of frame attachment face, lay respectively at the both sides of described mounting hole axis with the contacted flange of transparent panel.
For guaranteeing the effective sealing between frame and the transparent panel, the local evagination in the rear surface of described elastic seal ring forms boss, and the front surface evagination of described elastic seal ring is circular-arc; Have on the attachment face of described frame and the suitable groove of described boss, the boss of described elastic seal ring is nested in the groove of described frame.
The beneficial effects of the utility model are, good seal performance and be difficult for losing efficacy, transparent panel is stressed evenly, sealing install and using process in all be difficult for chipping, and assembling, convenient disassembly.
