Abstract
The utility model discloses a double-layer sealing ring. The cross section of the double-layer sealing ring is rectangular; and raised lines are arranged at the upper side and the lower side of the rectangle respectively. In the double-layer sealing ring, as the raised lines are respectively arranged at the upper side surface and the lower side surface of the double-layer sealing ring, and gaps exist among the raised lines when a cover is sealed tightly, the compression force of the double-layer sealing ring is greatly reduced, so that the cover is not easy to deform; and as the middle part of the cross section of the double-layer sealing ring is rectangular, the double-layer sealing ring can be assembled simply and conveniently.
Description
Technical field
The utility model relates to a kind of good airproof performance, double-layer seal circle convenient for assembly.
Background technique
The terminal box sealing means has several now, one of them the most general mode is placed seal ring exactly in lid, and what generally use on the market is that the cross section of seal ring is circular, but circular cross section is big to the requirement of lid compressive force, terminal box is long service time one like this, because reaction force, the lid easy deformation, simultaneously, the seal ring of circular cross-section requires than higher for the diameter validity of lid groove, and diameter is too little, and sealing effect can weaken, if diameter is too big, this is not easy to put into and covers groove.
Like this, satisfying under the requirement of society to sealing, provide a kind of good airproof performance, seal ring convenient for assembly is one of research topic of each manufacturer.
The model utility content
In order to address the above problem, the utility model provides a kind of good airproof performance to society, double-layer seal circle convenient for assembly.
The technical solution of the utility model is: design a kind of double-layer seal circle, the cross section of described double-layer seal circle is a rectangle, and the upside and the downside of described rectangle are respectively equipped with raised line.
As to improvement of the present utility model, the cross section of described raised line is triangle or polygonal.
As to improvement of the present utility model, the cross section of described raised line is semicircle.
As to improvement of the present utility model, described raised line number is one or more.
As to improvement of the present utility model, described double-layer seal circle is a ring.
As to improvement of the present utility model, described double-layer seal circle is polygon annular.
As to improvement of the present utility model, the outer ring of described double-layer seal circle is provided with immovable point.
As to improvement of the present utility model, described immovable point is polyhedron or semiround body.
As to improvement of the present utility model, described double-layer seal circle is made with silica gel.
As to improvement of the present utility model, described double-layer seal circle is made with rubber.
In the utility model, upper side and downside at described double-layer seal circle are respectively equipped with raised line, cover when tight because the existence in slit between the raised line at lid like this, reduced the compressive force of double-layer seal circle greatly, like this lid be not easy the distortion, and,, assemble up simple and convenient like this owing to be rectangle in the middle of its cross section.

Embodiment
Referring to Fig. 1 and Fig. 2, what Fig. 1 and Fig. 2 disclosed is a kind of double-layer seal circle, and described double-layer seal circle is to be the seal ring of rectangle 1 with the cross section that silica gel is made, and the upside of described rectangle 1 and downside are respectively equipped with raised line 11,12.In the present embodiment, the cross section of described raised line 11,12 is a triangle, each two raised line 11,12 of side about the double-layer seal circle, and in fact, the cross section of described raised line 11,12 can also be polygonal or semicircle; Raised line 11,12 numbers can be one or more; As can be seen from Figure 2, in the present embodiment, described double-layer seal circle is polygon annular, is provided with immovable point 13 on the outer ring, and the effect of immovable point 13 is when assembling, can very easily seal ring be positioned at and cover in the groove, and described immovable point 13 is a hexahedron.Obviously, described double-layer seal circle can also be a ring, and the shape of described immovable point can also be polyhedron or semiround body etc.Certainly, described double-layer seal circle can also be made of rubber except can making of silica gel.
See also Fig. 3, Fig. 3 is the cross-sectional view of a kind of user mode of Fig. 1.Embodiment illustrated in fig. 3 is the concrete application of the utility model on solar junction box, from figure as can be known, loam cake 2 and lower cover 3 at solar junction box are to seal with seal ring disclosed in the utility model, the cross section of described seal ring is a rectangle 1, respectively be provided with two raised lines 11,12 respectively on the bi-side up and down of rectangle, be provided with electrical apparatus element 4 in described lower cover 3, electrical apparatus element are diode in series, diode one end is connected with solar panels, and the other end is by lead 5 output electric energy.
