Abstract
The utility model relates to a seal structure between the cover and the box body of an earth box. For resolving the prior problems that the installation between the cover and the box body of the earth box is complex and wastes time, has low seal reliability and bad damp-proofing and flood-fighting capability, and the fittings is easy aging, the utility model provides a seal structure between the cover and the box body of an earth box, comprising a cover and an opened box body, wherein the cover is installed at the opening part of the box body, a sealing flange around the box body is fixedly connected at the opening part of the box body, a sealing member is fixed between the sealing flange and the cover, and the sealing flange is connected with the cover by bolts. The seal structure between the cover and the box body of the earth box of the utility model is easy for installing, and has good seal reliability and excellent damp-proofing and flood-fighting capability, and the fittings are less susceptible to age.
Description
Technical field
The utility model relates to a kind of ground connection case, more particularly, relates to the hermetically-sealed construction of a kind of ground connection case case lid and casing.
Background technology
The hermetically-sealed construction of existing ground connection case case lid and casing is to adopt flat seal cushion rubber, box sealing flange to reach seal case and case lid in the locking and the fit clearance of bolt, wherein casing and case lid are made by thin thin plate filling insulating material, its intensity a little less than, binding site box sealing flange is yielding during installation.Adopt this hermetically-sealed construction, it installs loaded down with trivial details consuming time, standard and standardization are poor, and because the binding site mechanical strength of casing and case lid is more weak yielding, thereby cause joining many drawbacks such as the product accessory is easily aging, not high, the moistureproof anti-flood capacity difference of sealing reliability, thereby can not satisfy the instructions for use of crosslinked cable metal sheath ground connection case under adverse circumstances.
The utility model content
The technical problems to be solved in the utility model is, at the existing ground connection case case lid and the hermetically-sealed construction of casing install loaded down with trivial details consuming time, join problems such as product accessory is easily aging, low, the moistureproof anti-flood capacity difference of sealing reliability, and provide that a kind of easy installation, accessory are difficultly worn out, ground connection case case lid that good airproof performance, moistureproof anti-flood capacity are strong and the hermetically-sealed construction of casing.
The technical scheme that its technical problem that solves the utility model adopts is: the hermetically-sealed construction that proposes a kind of ground connection case case lid and casing, comprise case lid, have a uncovered casing, described case lid is installed in the open-mouth of described casing, at the fixedly connected sealing flange that is provided with an around tank of casing open-mouth, be provided with seal between described sealing flange and the case lid, described sealing flange is connected with case lid by bolt.
In the hermetically-sealed construction of ground connection case case lid described in the utility model and casing, its face relative with case lid of described sealing flange is provided with around the uncovered linear grooves of casing, and described seal is the O RunddichtringO, and described O RunddichtringO is embedded in described linear grooves.
In the hermetically-sealed construction of ground connection case case lid described in the utility model and casing, described O RunddichtringO is industrial hydraulic pressure standard O RunddichtringO.
In the hermetically-sealed construction of ground connection case case lid described in the utility model and casing, described sealing flange is fixedly connected by welding on casing.
In the hermetically-sealed construction of ground connection case case lid described in the utility model and casing, the outer rim of described case lid has the flanging to the sealing flange lateral buckling.
Ground connection case case lid in the utility model is compared with the hermetically-sealed construction of casing with existing ground connection case case lid with the hermetically-sealed construction of casing, has following advantage:
1, the open-mouth at casing is provided with sealing flange, and the mechanical strength height of sealing flange is not yielding during installation, thereby convenience is installed, good airproof performance, also makes accessory be difficult for wearing out, improve moistureproof anti-flood capacity simultaneously.
2, the industrial hydraulic pressure standard of seal O RunddichtringO, because industrial hydraulic pressure standard O RunddichtringO has oil resistant, corrosion-resistant, ageing-resistant performance and elasticity is strong, mechanical strength is big, dimensional standard is strong, realizes the sealing installation of case lid and casing.
3, on sealing flange, be provided for placing the linear groove of O RunddichtringO, be convenient to fixed placement O RunddichtringO when mounted, thereby also reach convenient purpose of installing.
Description of drawings
The utility model is described in further detail below in conjunction with drawings and Examples, in the accompanying drawing:
Fig. 1 is the schematic diagram of the hermetically-sealed construction of ground connection case case lid and casing in the utility model.
Embodiment
See also shown in Figure 1, the hermetically-sealed construction of a kind of ground connection case case lid and casing, comprise case lid 2, has a uncovered casing 1, case lid 2 is installed in the open-mouth of described casing 1, the sealing flange 3 that is fixedly connected by welding and is provided with an around tank 1 at casing 1 open-mouth, its face relative with case lid 1 of sealing flange 3 is provided with around the uncovered linear grooves 4 of casing, industrial hydraulic pressure standard O RunddichtringO 5 is embedded in linear grooves 4, sealing flange 3 is connected with case lid 2 by bolt 6, the outer rim of case lid 2 has the flanging 7 to the sealing flange lateral buckling, and flanging 7 can help the sealing of 3 of case lid 2 and sealing flanges.
In the present embodiment, case lid 2 and casing 1 employing thickness are that 2 millimeters corrosion resistant plate manufacturing forms, sealing flange 3 adopts 10 millimeters corrosion resistant plate manufacturing to form, fixedly connected with casing 1 by welding, because the mechanical strength height of sealing flange 3, not yielding during installation, thus convenience is installed, good airproof performance, also makes O RunddichtringO 5 be difficult for wearing out, improve moistureproof anti-flood capacity simultaneously.Seal adopts industrial hydraulic pressure standard O RunddichtringO 5, because industrial hydraulic pressure standard O RunddichtringO has oil resistant, corrosion-resistant, ageing-resistant performance and elasticity is strong, mechanical strength is big, dimensional standard is strong, realizes the sealing installation of case lid and casing.On sealing flange, be provided for placing the linear groove of O RunddichtringO, be convenient to fixed placement O RunddichtringO when mounted, thereby also reach convenient purpose of installing.
