Abstract
The utility model relates to a table lid specifically discloses an ammeter lid, including casing and the lid of connection on the casing that is used for placing various electrical components and circuit, casing and lid are all transparent, be connected with the rubber circle between lid and the casing, the top of casing be equipped with with the annular recess of lid bottom assorted, the rubber circle sets up in the recess, lid and casing are the cylinder, just the bottom of lid is equipped with the internal thread, the top of casing is equipped with the external screw thread, the casing outer wall covers there is the layer of being in the light. This patent avoids the rubber circle by the problem of ultraviolet irradiation accelerated ageing, improves ammeter lid's waterproof performance.
Description
Technical field
This utility model relates to a kind of table cover, specifically discloses a kind of meter cover.
Background technology
Ammeter is a kind of instrument for measuring electric energy, is widely used in the places such as family, community, municipal administration, factory.Common ammeter is usually mounted to family's corridor corner, but for the domestic consumer in some suburbs or rural area, ammeter is generally all arranged on building outer surface wall.Traditional ammeter includes ammeter housing, housing is provided with lid, enclosure interior be hollow setting for placing various electric elements and circuit, lid bottom offers the groove cooperated with case outlines, housing outline is embedded in groove, connects housing and lid again through securing member.
Some ammeter in the market, in order to prevent sleety weather, water or moisture enter in housing from meter cover and housing junction, can be embedded a rubber ring, and then make ammeter sealing property better, reach the effect of waterproof in groove.
But ammeter of the prior art, in actual process engineering, in order to conveniently the person of checking meter reads the power consumption in ammeter, all can be processed into the plastic closure of transparence by lid.Under the ultraviolet radiation that summer is strong for a long time, this is irradiated on rubber ring to be directed through transparent plastic cover, causes rubber molecule chain break, and acceleration rubber ring is aging, therefore water resistance is deteriorated.
Utility model content
This utility model is intended to provide a kind of meter cover, aging by acceleration rubber ring after ultraviolet radiation to solve existing meter cover, the problem that water resistance is deteriorated.
For solving problem above, it is provided that following scheme:
The meter cover of this programme, meter cover, including the housing for placing various electric elements and circuit and the lid that is connected on housing, described housing and lid are all transparent；It is connected to rubber ring between described lid and housing；The top of described housing is provided with the groove of the annular matched with lid bottom, and rubber ring is arranged in groove；Described lid and housing are cylinder, and the bottom of described lid is provided with female thread, and the top of described housing is provided with external screw thread, and described lid and housing are threaded；Described housing exterior walls is coated with light blocking layer.
Operation principle and beneficial effect:
When on ultraviolet radiation to meter cover, ultraviolet is absorbed by the light blocking layer on housing so that it is can not pass through housing be irradiated on rubber ring, slow down the aging speed of rubber ring so that it is water resistance weaken slow down.Simultaneously as housing and lid are threaded, housing and lid is made can quickly to connect and dismantle, and because of lid at shell body interior so that dust and steam can all be kept off outside by lid well, it is to avoid enter the electric elements damaging in housing in housing.Rubber ring arranges the groove in housing rather than is arranged on the groove in lid, and when connecting housing and lid, rubber ring need not rotate along with lid, will not because of the situation occurring evolution in rotation process.In whole connection procedure, rubber ring is all attached to not shifting one's position on the groove of housing, enables rubber ring to be more stably connected between housing and lid, it is to avoid because rubber ring position is moved to cause and occurred gap between housing and lid.
Further, described rubber ring is the annular with matching grooves.Enable rubber ring to be filled up completely with groove so that sealed environment between housing and lid, can be formed, effectively stop dust and steam to enter.
Further, described lid is hinged with renovates；Described renovate block lid end face and described in the end face renovated be coated with light blocking layer.Lid end face is sheltered from by convenience by renovating, it is to avoid ultraviolet is injected in housing from lid end face, slows down the aging speed of the electric elements in housing and circuit.
Further, described light blocking layer is ceramic layer.The characteristics such as the heat-and corrosion-resistant by pottery itself, absorb and block ultraviolet so that it is the infringement that the electric elements in housing, circuit and rubber ring are caused is preferably minimized, it is to avoid rubber ring accelerated ageing because of ultraviolet radiation, affect the water resistance of meter cover.
Further, described ceramic layer is aluminium nitride ceramics layer.Aluminium nitride ceramics thermal conductivity is high, and the coefficient of expansion is low, and intensity is high, high temperature resistant, resistance to chemical attack, and resistivity is high, and dielectric loss is little, can play the good effect of being in the light, and can play again good thermolysis.
Accompanying drawing explanation
Fig. 1 is the structural representation of this utility model embodiment；
Fig. 2 is the structural representation of the housing of this utility model embodiment.
Detailed description of the invention
Below by detailed description of the invention, this utility model is described in further detail:
Accompanying drawing labelling in Figure of description includes: lid 1, housing 2, groove 3, rubber ring 4, renovate 5, fixing axle 6.
As it is shown in figure 1, meter cover, including being cylindrical housing 2 and lid 1.Housing 2 is the hollow structure of opening upwards, is used for placing various electric elements and circuit.As in figure 2 it is shown, the outer surface of housing 2 has external screw thread, the top inner side of housing 2 has the groove 3 of annular.The outside of housing 2 scribbles aluminium nitride ceramics layer, is used for blocking groove 3.
As it is shown in figure 1, lid 1 is the hollow structure that Open Side Down, the bottom of lid 1 has the female thread matched with housing 2.Lid 1 is transparent, lid 1 is hinged with by fixing axle 6 and renovates 5；Renovate 5 can block lid 1 end face completely and renovate the end face of 5 and be coated with aluminium nitride ceramics layer for being in the light.Renovate 5 to rotate around fixing axle 6, it is achieved renovate 5 and open and cover lid 1, facilitate behaviour table person to open and renovate 5 and check meter, then will renovate 5 at ordinary times and cover on lid 1 as lid 1 shading.Avoid ultraviolet to inject in housing 2 from lid 1 end face, slow down the aging speed of the electric elements in housing 2 and circuit.
Rubber ring 4 is the annular mated with groove 3.Make rubber ring 4 can be filled up completely with groove 3 so that sealed environment between housing 2 and lid 1, can be formed, effectively stop dust and steam to enter.Rubber ring 4 is connected to the groove 3 in housing 2 rather than is arranged on the groove 3 in lid 1 so that convenient when installing rubber ring 4, because when connecting and dismantle meter cover, housing 2 is motionless, and rotation is lid 1.
Above-described is only embodiment of the present utility model, and in scheme, the general knowledge such as known concrete structure and characteristic does not do too much description at this.Should be understood that; for a person skilled in the art, under the premise without departing from this utility model structure, it is also possible to make some deformation and improvement; these also should be considered as protection domain of the present utility model, and these are all without affecting effect and the practical applicability that this utility model is implemented.The protection domain that this application claims should be as the criterion with the content of its claim, and the detailed description of the invention in description etc. records the content that may be used for explaining claim.
