Abstract
The utility model relates to the manufacture field of refrigerators, in particular to a sealing strip used for a refrigerator door. According to an existing sealing strip of a refrigerator door, in particular to a sealing strip of a double door refrigerator, due to magnetism, failure of the sealing strip is easily caused after the refrigerator is closed and opened during long-time use, and therefore the sealing strip used for the refrigerator door is provided. The sealing strip comprises an air bag, installation feet and lips and further comprises PVC installation feet with hardness more than 80. The problems of airtight performance of the sealing strip of the refrigerator door and the refrigerator door and long-term effectiveness of the sealing strip of the refrigerator door are simultaneously solved.
Description
Technical field
The present invention relates to the manufacturing field of refrigerator, particularly relate to the sealing strip that is used for refrigerator doors.
Background technology
Existing refrigerator doors sealing strip mostly is made up of members such as magnetic stripe 1, air bag 2, installation foot 3 and lip limits 4, and the mode by extrusion molding obtains gasket structure as shown in Figure 1, and each structure is the flexible PVC structure, and installation foot 3 is the flexible PVC installation foot.
We find the client in use, and constantly closing refrigerator repeatedly because the refrigerator doors sealing strip is subjected to the magnetic attraction of refrigerator repeatedly, causes the refrigerator doors sealing strip to be pulled out easily, to lose efficacy behind the door.And then causing that the refrigerator sealing weakens, a large amount of cold air leak.Not only influence the normal use of refrigerator, and cause high frequent to start, power consumption increases.
Summary of the invention
The utility model is at present refrigerator doors sealing strip, the sealing strip of double-door refrigerator particularly, because magneticaction, in the long-time problem that causes sealing strip from refrigerator doors, to break away from easily after the use that opens and closes, a kind of sealing strip that is used for refrigerator doors is provided, comprise air bag, installation foot, lip limit and magnetic stripe, comprise that also hardness is the PVC installation foot more than 80.More preferably, the invention also discloses the PVC structure that described air bag and lip limit are hardness 67 ~ 73.Further, the invention also discloses described installation foot and air bag, the lip limit is the integrally formed structure that mould squeezes out simultaneously.
Compared with prior art, the utlity model has following beneficial effect:
1. gasket structure disclosed in the utility model, the driving fit effect of sealing strip can be normally realized on its top; The installation stability between sealing strip and the refrigerator doors can be realized in its underpart; Thereby guarantee that the long-term back sealing strip that uses did not lose efficacy.
2. by the forming mode of mould extruding, can combine, not need extra increase shaping flow process with existing refrigerator doors sealing strip forming technology.
3. mould is divided into upper and lower two parts, carries out flexible PVC extrusion molding and hard PVC extrusion molding then respectively, top is soft, the integrative-structure of bottom hard thereby finish simultaneously in a technological process, and the stability of structural entity is higher.
In a word, adopt technical scheme disclosed in the utility model after, solved the problem of refrigerator doors sealing strip and refrigerator doors adaptation and refrigerator doors sealing strip long-term effectiveness simultaneously.
Description of drawings
Fig. 1 is a refrigerator doors sealing strip schematic diagram of the prior art;
Fig. 2 is a refrigerator doors sealing strip schematic diagram of the present utility model;
Wherein:
1-magnetic stripe, 2-air bag, 3-installation foot, 4-lip limit.
The specific embodiment
Below in conjunction with the drawings and specific embodiments, further illustrate the utility model, should understand the following specific embodiment only be used to the utility model is described and be not used in the restriction scope of the present utility model.Need to prove, describe below the word " preceding " that uses, " back ", " left side ", " right side ", " on " and D score refer to direction among the width of cloth figure, word " interior " and " outward " refer to respectively towards or away from the direction of specific features geometric center.
A kind of sealing strip that is used for refrigerator doors comprises air bag 2, installation foot 3, lip limit 4 and magnetic stripe 1, and described installation foot 3 is a hard PVC installation foot 3.
During production, respectively different PVC extrusion moldings is adopted with the lower part in the top of mould, it is that the PVC extruding of hardness between 67 ~ 73 forms air bag 2, lip limit 4 that flexible PVC is adopted on its top, and magnetic stripe 1 is loaded in the air bag 2, the hard PVC of its underpart employing meanwhile is that hardness is at the PVC extrusion molding installation foot 3 more than 80, hard PVC has improved the stability after installation foot 3 installations, after preventing long-term the use, installation foot 3 stretches repeatedly, shrinks, thereby distortion, inefficacy, increase the sealing of refrigerator doors, avoided cold air to reveal, reached energy-conservation purpose.
Technical scheme disclosed in this invention is not limited only to the disclosed technical scheme of the foregoing description, also comprises by above technical characterictic making up the technical scheme of being formed arbitrarily.
The above is the specific embodiment of the present utility model; should be pointed out that for those skilled in the art, under the prerequisite that does not break away from the utility model principle; can also make some improvements and modifications, these improvements and modifications also are considered as protection domain of the present utility model.
Claims (3)
1. be used for the sealing strip of refrigerator doors, it is characterized in that: comprise air bag, lip limit and magnetic stripe, comprise that also hardness is the PVC installation foot more than 80.
2. the sealing strip that is used for refrigerator doors according to claim 1 is characterized in that: described air bag and lip limit are the PVC structure of hardness 67 ~ 73.
3. the sealing strip that is used for refrigerator doors according to claim 1 and 2 is characterized in that: described installation foot and air bag, lip limit are the integrally formed structure that mould is extruded simultaneously.
