Abstract
The utility model discloses a sealing structure of a refrigerator door, which comprises a door liner and a door seal strip. A clamping groove is arranged on the liner, a clamping strip is correspondingly arranged on the door seal strip, the clamping strip is arranged inside the clamping groove, two barb-type elastic seal strips are symmetrically arranged at the front end of the clamping strip, and the ends of the elastic seal strips are abutted against the inner wall of the clamping groove. The two barb-type elastic seal strips are arranged at the end of the clamping strip, and the elastic seal strips are tightly attached to the inner wall face of the clamping groove after deformation by stress to fix the door seal strip. Accordingly, the sealing structure not only increases assembling efficiency, but also has better sealing function, effectively reduces convection of refrigerator inner air and outer air, and increases refrigerating performance.
Description
Technical field
The utility model relates to a kind of refrigerator door, relates in particular to a kind of hermetically-sealed construction of refrigerator door.
Background technology
Present refrigerator door sealing has only a kind of mode: as shown in Figure 1, the one, the card article on the gasket 24 is embedded in the draw-in groove 3 of door inner bag 1, be arranged with two card angles 11 on the card article 4, card angle 11 tightly offsets with draw-in groove 3, make card article 4 can in draw-in groove 3, not detach easily, be covered with on the surface of door inner bag 1 simultaneously and intercept the skin (not shown), intercepting skin is the flexible plastic skin.The carrying magnetic face is adjacent to refrigerator case mouth, seal up refrigerator case mouth, gasket 2 extruding make that intercepting skin is close to an inner bag 3 surfaces, and after in the card article 4 embedding draw-in grooves 3, card angle 11 also is close to draw-in groove 3 internal faces, prevents air and case outer air generation convection current in the refrigerator case thereby play.
The weak point of this method is: in the door courage draw-in groove 3 with the ABC of body of card article 4 pincers, form card article and draw-in groove seal face, it is too little that this end face connects contact area, can better not prevent the convection current that interior air of refrigerator case and case outer air produce, indicated as arrow among the figure that air externally produces the flow direction of convection current in the case, air flows through from the gap that door inner bag 1 is appeared on the stage between terrace 7 and gasket 2 upper ends in the case, because between gasket 2 and the door inner bag 1, the contact-making surface that blocks between angle 11 and the draw-in groove 3 is less, be easy to generate the gap, flow out so have air, influence refrigeration.
Summary of the invention
The utility model has solved above-mentioned deficiency of the prior art, provide a kind of sealing stable, firm refrigerator door hermetically-sealed construction, the utility model is to be provided with two in the card article end to be barb-like resilient seals, thereby resilient seals compressive deformation generation elastic force is close to the draw-in groove internal face gasket is fixed, not only improve efficiency of assembling, but also played multi-layer sealed effect; And door inner bag surface and draw-in groove internal face be covered with the obstruct skin, the gasket upper end is provided with several and the perpendicular retaining that the door inner bag offsets, and formed the effect that more piece intercepts air, more effectively reduced air and the convection current of case outer air in the refrigerator case; Improved the refrigeration performance of product.
The technical solution of the utility model is achieved in that
A kind of hermetically-sealed construction of refrigerator door, comprise an inner bag, gasket, on the door inner bag, be provided with draw-in groove, correspondence is provided with card article on the gasket, described card article is fastened in the draw-in groove, be arranged with two at the front end of card article and be barb-like resilient seals, the end of described resilient seals and the inwall of draw-in groove offset.
As preferably, be provided with several perpendicular retainings in the upper end of gasket, the step surface on the upper end of described perpendicular retaining and the door inner bag offsets.Perpendicular retaining has also played the effect that intercepts air.
As preferably, be provided with two perpendicular retainings in the upper end of gasket, two perpendicular retainings are separately positioned on the limit portion and the middle part of gasket upper end.
As preferably, be covered with in order to intercept the obstruct skin of air on the surface of door inner bag and the internal face of draw-in groove.
The advantage that the utlity model has is:
(1), easy to assembly, the efficient height, the fixing-stable of gasket is reliable;
(2), multilayer intercepts air, and door body better tightness has more effectively reduced the convection current that interior air of refrigerator case and case outer air produce, and has improved the refrigeration performance of product.
Description of drawings
Fig. 1 is the sealed structural representation of prior art refrigerator door;
Fig. 2 is a door body sealed structural representation of the present utility model.
The specific embodiment
The specific embodiment of the present utility model is as follows:
Embodiment: as shown in Figure 2, a kind of hermetically-sealed construction of refrigerator door, comprise an inner bag 1, gasket 2, on door inner bag 1, be provided with draw-in groove 3, correspondence is provided with card article 4 on the gasket 2, described card article 4 is fastened in the draw-in groove 3, is arranged with two at the front end of card article 4 and is barb-like resilient seals 5, and the inwall of the end of described resilient seals 5 and draw-in groove 3 offsets.Resilient seals 5 produces elastic force by compressive deformation and is close to inner bag draw-in groove 3, not only can better contact an inner bag draw-in groove inwall, has played better sealing function, can also play the effect of good fixed gate strip of paper used for sealing; And gasket is difficult in and just is difficult to extract after knocking in, and resilient seals 5 has also played the effect of barb.
Be provided with limit portion and middle part that 6, two perpendicular retainings 6 of two perpendicular retainings are separately positioned on gasket 2 upper ends in the upper end of gasket 2, the step surface 7 on the upper end of described perpendicular retaining 6 and the door inner bag 1 offsets.Be covered with in order to the obstruct skin that intercepts air (among the figure sign) at the internal face of the surface of door inner bag 1 and draw-in groove 3.
Resilient seals 5 produces elastic force by compressive deformation and is close to the effect that the inner bag draw-in groove has played sealing, increased the perpendicular retaining of obstruct skin and combination in addition, played the effect of multilayer obstruct air, door body better tightness, more effectively reduce the convection current that interior air of refrigerator case and case outer air produce, improved the refrigeration performance of product.When gasket need be changed, gasket is extracted one jiao along the opposite direction of direction of insertion, firmly extract again and get final product.
Claims (4)
