Abstract
The utility model relates to a viewing mirror for water-level meter, which is designed for improving the unclear black-white interface of the prior black-white viewing mirror for water-level meter. The viewing mirror for water-level meter is a transparent mirror body whose one side face is provided with an embolic reflecting body. The section of the reflecting body is an isosceles triangle. The base line of the triangle is below the sealing surface and the apical angle of the triangle is larger than 90 and is above one side face. The utility model has the advantage of that: when the viewing mirror for water-level meter is used for metering the water level, the interfaces with water or without water are clearer. The waterless part of the water-level meter displays the white and the part with water of the water-level meter displays the black. Furthermore, the viewing mirror has simpler processing, easy cleaning and low cost.
Description
Technical field
The utility model relates to a kind of visor, particularly relates to the visor that a kind of water level gauge shows usefulness.
Background technology
The water level gauge visor is the indispensable element of black and white water-level meter.The one side of its contact water of the visor that existing black and white water-level meter is used has a strip bulge more lower slightly than sealing surface, and the xsect of strip bulge is a triangle, and drift angle is 90 °, and leg-of-mutton two right angle faces form two reflectings surface.Though can produce the black and white interface when it is used for water level gauge, also have following shortcoming: the black and white interface is unintelligible, clean inconvenient.
Summary of the invention
Technical problem to be solved in the utility model is to overcome the above-mentioned shortcoming of prior art and a kind of water level gauge visor is provided, to reach better white and black displays interface.
The utility model solves the problems of the technologies described above the technical scheme that is adopted:
The water level gauge visor is transparent mirror body, it is characterized in that it is the reflecting body of isosceles triangle that there is the cross section of caving in a side, and leg-of-mutton base is lower than sealing surface, and leg-of-mutton drift angle is greater than 90 and be higher than a side.
Described cross section is that leg-of-mutton reflecting body has continuous two, also can have a plurality ofly, and the interface of Chan Shenging is more clear like this.
The whole shape of transparent mirror body can be varied, can be ellipse, rectangle or the like.
Compared with prior art, when advantage of the present utility model is that it is used for water level gauge, there are water and anhydrous interface more clear.No water section in the water level gauge is shown as white, has water section to be shown as black.And this visor processing is simpler, cleans easily, and cost is low.

Fig. 4 is the B-B sectional view of Fig. 3.
Embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
Embodiment 1:
As shown in Figure 1 and Figure 2, the water level gauge visor has the reflecting body 2 of a cross section of caving in as isosceles triangle on one side 1 sealing surface of water level gauge (when the using as), and leg-of-mutton base is lower than side 1, the number of degrees of leg-of-mutton drift angle are 100 °, and its drift angle surpasses side 1.
Its whole mirror phosphor bodies be shaped as rectangle.
As long as leg-of-mutton drift angle is greater than 90 °, and the black and white interface is just more clear.
Embodiment 2:
As shown in Figure 3, Figure 4, the water level gauge visor, on the one side 1 sealing surface of water level gauge (when the using as) reflecting body 2 of two cross sections of caving in as isosceles triangle arranged, reflecting body 2 adjacent connections, leg-of-mutton base is lower than side 1, the number of degrees of leg-of-mutton drift angle are 100 °, and its drift angle is all above side 1.
Its whole mirror phosphor bodies be shaped as rectangle.
As long as leg-of-mutton drift angle is greater than 90 °, and the black and white interface is just more clear.
Claims (2)
1, water level gauge visor is transparent mirror body, it is characterized in that: it is the reflecting body of isosceles triangle that there is the cross section of caving in a side, and leg-of-mutton base is lower than sealing surface, and leg-of-mutton drift angle is greater than 90 and be higher than a side.
2, water level gauge visor as claimed in claim 1 is characterized in that: described cross section is that leg-of-mutton reflecting body has continuous two or more.
