Abstract
The utility model relates to a peeping window for a glove box, and belongs to the technical field of nuclear chemical machinery. The peeping window comprises a window frame flange, a glass plate, a window frame pressing plate and a sealing ring, wherein the appearance of the glass plate is matched with the shape of an inner hole of the window frame flange; the outer opening of the inner hole of the window frame flange extends inwards and is provided with a stop edge with a peripheral outer embedded groove; the pressing plate is provided with a ring which is matched with the shape of the inner hole of the flange, the outer end face of the ring is provided with a circumferential embedded groove, and the inner end of the ring extends outwards to form a pressing edge; after assembly, the pressing plate is fixedly connected with the flange through fasteners distributed at intervals on the periphery, and the glass plate is clamped between the outer end face of the pressing plate and the stop edge of the flange; and sealing elements are respectively embedded in the external embedding groove and the internal embedding groove. After the glass plate clamping device is adopted, the installation is very convenient due to the simple structure, and the structure that the outer end surface of the pressure plate and the flange stopping edge respectively clamp the glass plate through the embedded sealing piece is not only stable and reliable, but also has large rubber ring compression allowance and ideal sealing effect.
Description
Technical Field
The utility model relates to a peep window, in particular to a glove box peep window, and belongs to the technical field of nuclear chemical machinery.
Background
In the nuclear materials manufacturing and processing industry, equipment such as glove boxes must be accurately operated with a sight glass through which the internal environment can be observed.
As a result of the search, chinese patent application No. CN201921314050.1 discloses a glove box peep window structure, which includes a window frame, a multi-layer gasket, a multi-layer glass, and a pressing plate, and is connected to a glove box thick-wall layer by large screws after being assembled. The peep window is tightly pressed on the mounting ring plate through the sealing ring to ensure sealing. The technical scheme has the defects of complex structure and unsatisfactory sealing effect.
Disclosure of Invention
The utility model aims to: aiming at the defects in the prior art, the glove box peeping window is simple in installation structure and ideal in sealing performance.
In order to achieve the purpose, the basic technical scheme of the glove box peep window is as follows: the glass plate is matched with the flange in shape; the outer opening of the inner hole of the flange extends inwards and is provided with a stop edge with a peripheral embedded groove; the pressing plate is provided with a ring which is matched with the shape of the inner hole of the flange, the outer end face of the ring is provided with a circumferential inner embedded groove, and the inner end of the ring extends outwards to form a pressing edge; after assembly, the pressing plate is fixedly connected with the flange through fasteners distributed at intervals on the periphery, and the glass plate is clamped between the outer end face of the pressing plate and the stop edge of the flange; and sealing elements are respectively embedded in the outer embedded groove and the inner embedded groove.
After the glass plate clamping device is adopted, the installation is very convenient due to the simple structure, and the structure that the outer end surface of the pressure plate and the flange stopping edge clamp the glass plate respectively through the embedded sealing piece is not only stable and reliable, but also has ideal sealing effect.
The utility model has the further perfection that: the inner contour of the ring is matched with the inner contour of the stop edge.
The utility model has the further improvement that: the thickness of the pressing plate is reduced, the thickness of the holding edge is reduced, and the thickness of the glass plate is matched with the thickness of the flange minus the thickness of the stop edge.
The utility model has the further perfection that: the inner end of the flange forms a step spigot.
Drawings
The present invention will be described in further detail with reference to the following specific embodiments and the accompanying drawings.
Fig. 1 is a schematic structural diagram of an embodiment of the present invention.
Fig. 2 is a schematic sectional structure view of B-B of fig. 1.
Fig. 3 is a schematic perspective view of the embodiment of fig. 1.
Detailed Description
Examples
The glove box peeping window of the embodiment is mainly composed of a rectangular flange 1, a glass plate 2, a pressing plate 3, a sealing member 4 and a fastening member 5, as shown in fig. 1 to 3.
The flange 1 is matched with an installation hole on the glove box and welded with the glove box shell, and the outer opening of the rectangular inner hole of the flange extends inwards to form a stop edge 1-1 with a peripheral outer embedded groove 1-2 on the inner side. The outer shape of the glass plate 2 is matched with the shape of the inner hole of the flange 1.
The pressing plate 3 is provided with a rectangular ring matched with the shape of an inner hole of the flange 1, the inner contour of the ring is matched with the inner contour of the stop edge 1-1, the outer end face of the ring is provided with a circumferential inner embedded groove 3-2 corresponding to the outer embedded groove 1-2, and the inner end of the ring extends outwards to form a pressing edge 3-1. Because the thickness of the pressure plate is reduced, the thickness of the holding edge is added, and the thickness of the glass plate is matched with the thickness of the flange minus the thickness of the stopping edge, when the glass plate is assembled, after the sealing pieces 4 are respectively embedded in the outer embedded groove 1-2 and the inner embedded groove 3-2, the pressure plate 3 is fixedly connected with the flange 1 through the fastening pieces 5 distributed at intervals on the periphery, so that the glass plate 2 can be clamped between the outer end surface of the pressure plate 3 and the stopping edge of the flange 1, the fixation is reliable and stable, the sealing is ideal, and the glass plate can be protected. In addition, the inner end of the flange 1 forms a step spigot, so that the flange is convenient to weld with a glove box during installation.
In addition to the above embodiments, the present invention may have other embodiments. All technical solutions formed by using equivalent transformation or equivalent transformation fall within the protection scope of the present invention.
