Abstract
This invention discloses a box body sealing device and a seal box. The box body sealing device comprises a box frame and a first card slot which is installed on the frame of the box body by pressing; a first sealing strip is positioned within a first card slot; the frame of the box body is positioned on the first sealing strip by pressing; the box body frame is fixedly provided with a frame plate which forms a second card slot with the box body frame; the opening of the second card slot is opposite to that of the first card slot; and a second sealing strip is arranged within the second card slot; one side wall of the first card slot is pressed on the second sealing strip. This invention adds a sealing layer between a door plate and a box body frame through the second card slot and the second sealing strip so as to achieve a double-sealing effect. In this way, even after a period of time of weathering, the deformation of the sealing strip positioned on the outside could affect the sealing effect, but the sealing strip inside is isolated from the outside of the box body, the sealing effect is not impacted by the weathering and the sealing effect is good.

Fig. 2 is along A-A to cutaway view in Fig. 1;
The schematic diagram of the case body sealing device that Fig. 3 provides for the embodiment of the present invention one;
The schematic diagram of the case body sealing device that Fig. 4 provides for the embodiment of the present invention two.
Embodiment
As shown in Figure 3, the embodiment of the present invention provides a kind of case body sealing device, this device comprises casing frame 1 and is fitted in the first draw-in groove 30 on casing frame 1, in the first draw-in groove 30, be placed with the first sealing strip 2, casing frame 1 is installed with on the first sealing strip 2, on casing frame 1 wall, be fixed with deckle board 4, this deckle board 4 and common second draw-in groove that forms of casing frame 1, this second draw-in groove is relative with the first draw-in groove 30 openings, a side wall and pressure that is placed with the second sealing strip 5, the first draw-in grooves 30 in the second draw-in groove is located on this second sealing strip 5.
Between deckle board 4 and casing frame 1, can adopt and be welded and fixed.Here in 30 two sidewalls of the first draw-in groove, whichever sidewall is installed with to coordinate with the second sealing strip 5 and does not all affect sealing effectiveness.The concrete shape of the first draw-in groove and the second draw-in groove cross section can be U-shaped, V-arrangement, trapezoidal, semicircle etc.
Prior art scheme is by the mutual pressure-acting between casing frame 1 and the first sealing strip 2, guarantee the isolated of box house and extraneous air, reach the effect of sealing, by exposing to the weather of a period of time, the first sealing strip easily distortion is aging, thereby cause casing frame 1 and the first sealing strip 2 contact-making surfaces loosening, seal failure.And improved sealing device as shown in Figure 3: weld a deckle board 4 on casing frame 1, form one the draw-in groove of adhesive tape can be installed, then the second sealing strip 5 is installed, form so again the sealing of door-plate and casing frame, both reached the effect of double-layer seal, even like this through exposing to the weather after a while, the first sealing strip 2 that is positioned at outside has distortion and has affected sealing effectiveness, but the second sealing strip 5 that is positioned at inner side is isolated with casing perimeter all the time, sealing effectiveness is not exposed to the weather by casing outside to be affected, sealing effectiveness is good.Be out of shape thereby solved because of individual layer adhesive tape the box sealing inefficacy causing, extended the useful life of casing.
As the preferred implementation of above-described embodiment, deckle board 4 cross sections are L-shaped, and wherein one end is fixed on casing frame 1 wall, and the other end suspends and be identical with the bearing of trend at casing frame 1 edge.Simple in structure and be easy to manufacture.
Simultaneously for guarantee deckle board 4 because of and the first draw-in groove sidewall between co-acting force cause distortion, between casing frame 1 and deckle board 4, fix gusset 6.Gusset 6 is triangular in shape, and stability is better.
As shown in Figure 1, Figure 3, the embodiment of the present invention also provides a kind of stuffing box, sealing case comprises having the casing 10 of opening and be installed with on this opening and for sealing the door-plate 3 of this opening, between door-plate 3 and casing 10, seal by sealing device, sealing device is any case body sealing device, the casing frame 1 of case body sealing device is fixedly connected with or is wholely set with the edge of opening of casing, and the first draw-in groove 30 is fixed on door-plate 3 inwalls.
The present invention program is keeping, on the basis of original adhesive tape sealing, newly increasing a seal point contacting with door-plate on casing, is reaching like this effect of dual-seal.As shown in Figure 3: first wind and rain corrodes i.e. the first sealing strip 2 of original sealing joint strip, is that the second sealing strip 5 is to touch casing external environment condition and newly increase sealing joint strip, and not exposed to the weather by outside affects, all the time in excellent sealing state.Like this, though the first sealing strip 2 because exposing to the weather after aging distortion, the second sealing strip 5 also can guarantee that excellent sealing effect can guarantee the sealing effectiveness that casing is long-term.
As the embodiment of above-described embodiment, as shown in Figure 3, deckle board 4 is fixed on the inwall of casing frame 1, and the first draw-in groove 30 madial walls 32 are installed with on the second sealing strip 5.As shown in Figure 4, the first draw-in groove 30 lateral walls 31 are installed with on the second sealing strip 5.
Certainly deckle board also can be fixed on the outer wall of casing frame.Specifically be installed with on the inwall that mode and deckle board be fixed on casing frame 1 identically, the first draw-in groove madial wall is installed with on the second sealing strip.The first draw-in groove lateral wall is installed with on the second sealing strip.Not shown in the figures.
Finally it should be noted that: above each embodiment, only in order to technical scheme of the present invention to be described, is not intended to limit; Although the present invention is had been described in detail with reference to aforementioned each embodiment, those of ordinary skill in the art is to be understood that: its technical scheme that still can record aforementioned each embodiment is modified, or some or all of technical characterictic is wherein equal to replacement; And these modifications or replacement do not make the essence of appropriate technical solution depart from the scope of various embodiments of the present invention technical scheme.
