Abstract
The utility model discloses a sealing device, which comprises a seal ring and a component, wherein a front sealing surface used for contacting a front contacting surface of equipment is formed on the end face of one side of the seal ring, a side sealing surface used for contacting a side contacting surface of equipment is further formed on the end face of the side of the seal ring, and the component is provided with a fixing structure used for fixing the seal ring. The sealing device has the advantages that the sealing device enlarges the contact area between the sealing device and the equipment, simultaneously enables sealing surfaces between the sealing device and the equipment to be more three-dimensional, and effectively reduces the dependence on an existing component which only generates positive pressure to seal contacting surfaces in an existing sealing process. The problems that the over-dependence on the component possibly causes the lack of the positive pressure, and equipment is damaged due to sealing-property insufficiency caused by the lack of the positive pressure are resolved.
Description
Technical field
The utility model relates to seal arrangement, relates in particular to the seal arrangement that is used for outdoor communication equipment.
Background technique
At present, outdoor equipment, especially communication apparatus need the scene to open equipment mostly and carry out project installation, again the equipment of opening are recovered to reseal reduction after the installation.But owing to adopting the seal ring plane to compress sealing between structural member and the equipment.The sealing principle of this conventional seals part needs structural member can give the impacting force of the enough and appropriateness of Sealing, makes that the Sealing between the junction plane of structural member and equipment produces positive compressive strain, thereby reaches the seal request of equipment.
But reality is, every equipment is when engineering site is installed, behind project installation personnel's Unclosing structure spare, after equipment installs, when structural member being set back, because the field condition restriction, installation personnel quality is uneven in addition again, the structural member that has gives the impacting force of sealing less, and what have is big; And the structural member that has is not just given Sealing impacting force etc.Will produce structural member and give the impacting force deficiency of Sealing, inhomogeneous, make the malleation amount of deformation of the Sealing between the junction plane of structural member and equipment not reach designing requirement, cause the equipment blow-by, when equipment produces negative pressure, water or moisture will access arrangements, make device damage.
Summary of the invention
The technical problems to be solved in the utility model provides a kind of equipment sealability and seal arrangement simple in structure of strengthening.
In order to address the above problem, the utility model provides a kind of seal arrangement, comprising:
Seal ring is formed with on one side end face of described seal ring and is used for and the contacted positive sealing surface of the positive surface of contact of equipment, also is formed with the contacted side sealing face of side contacts face that is used for equipment on this side end face;
Structural member, described structural member is provided with the fixed structure that is used for fixing described seal ring.
Preferably, described seal ring is provided with the penetration hole in order to fixing described seal ring that can pass fastening piece.
Preferably, on described structural member, be formed with mounting hole, the opposite side end face of described seal ring be provided with can be embedded in the described mounting hole boss.
Preferably, described boss is provided with step hole at core vertically, and this step hole comprises first endoporus and second endoporus, and the internal diameter of described first endoporus is less than the internal diameter of second endoporus; Described penetration hole and described second endoporus, the coaxial successively setting of first endoporus.
Preferably, described fastening piece is a screw.
The utlity model has following advantage: the area of contact that has increased seal arrangement and equipment, the sealing surface that makes seal arrangement and equipment simultaneously is three-dimensional more, effectively reduce depend in the conventional seals structural member only produce positive pressure to the contact face seal, that to such an extent as to it may cause because the sealing that the positive pressure deficiency causes is not enough, and make device damage; The utility model is simple in structure, reliable performance, the complexity of field engineering personnel operation of reducing greatly; Simultaneously, the cheap and highly versatile of the utility model fabricating cost, be convenient to produce in batches and promote the use of.
