Abstract
The utility model discloses a refrigerator door sealing strip which comprises a magnetic strip, an air bag, a mounting foot and a lip. The mounting foot is of a U-shaped structure and coats a convex groove of a refrigerator door liner, each of the magnetic strip, the air bag, the mounting foot and the lip is made by a soft PVC (polyvinyl chloride) material, and a hard PVC material is additionally mounted in the inner wall of the mounting foot. By changing a mounting structure of the mounting foot and the refrigerator door liner, stability in assembling is improved. In addition, the refrigerator door sealing strip has the advantages of convenience in manufacturing and good heat-insulating effect.
Description
Technical field
The utility model relates to a kind of refrigerator accessory, is specifically related to a kind of refrigerator door sealing strip.
Background technology
In order to prevent that refrigerator cold air from leaking; on refrigerator door liner, conventionally refrigerator door sealing strip can be installed; referring to Fig. 1; in the prior art; refrigerator door sealing strip is consisted of magnetic stripe 1, air bag 2, installation foot 3 and lip limit 4, and installation foot 3 is upside-down triangle shape, inserts the groove of door courage 5; remainder fits tightly other position at door courage, completes sealing.Described refrigerator door sealing strip adopts soft PVC material conventionally, by the mode of extrusion molding, has produced.
When producing and use, we find that above-mentioned refrigerator sealing strip exists some shortcomings part, is specially: 1, door bladder structure complicated (being in particular groove part), the cost of mfg. moulding die is higher.2, the effect of heat insulation at door seal place is general, easily occurs drenching dew phenomenon.3, the refrigerator door sealing strip of flexible PVC material, in the links such as manufacture, carrying, is easily out of shape and causes scrapping.
Utility model content
The purpose of this utility model is to overcome above-mentioned the deficiencies in the prior art, and a kind of Stability Analysis of Structures, easily manufactured, the better refrigerator door sealing strip of effect of heat insulation are provided.
A refrigerator door sealing strip, comprises magnetic stripe, air bag, installation foot and lip limit, and described installation foot is connected with refrigerator door liner; Described installation foot is U-shaped structure, and the refrigerator door liner place joining with it is tongue shape, and described installation foot is coated on the tongue place of this refrigerator door liner.
Described magnetic stripe, air bag, installation foot and lip limit all adopt flexible PVC material to make, and in the inwall of described installation foot, add hard PVC material.
The beneficial effects of the utility model are embodied in:
1. by groove, change the installation place of refrigerator door liner and installation foot into tongue, in the manufacture process of door courage, enter expanding foam solution in tongue, door seal place effect of heat insulation is better, and loss of refrigeration capacity tails off, and energy consumption is had to certain contribution, also can significantly improve to drench and reveal phenomenon simultaneously; In addition the designs simplification of door courage a lot, mould becomes simply, qualification rate and the efficiency of the production of door courage plastics sucking moulding obviously improve.
2. assembling is easier, has improved the production efficiency of assembling.
3. the pulling capacity after refrigerator door sealing strip and the assembling of door courage there are certain requirements, and this Standard is tighter, and pulling capacity is larger.
4. door seal changes to soft-hard coextrusion material (soft pvc+hard PVC) by full softwood matter (soft pvc), and anti-deformation is had clear improvement.Existing PVC door seal, because be soft, in production, carrying, deposits, assembling, links, slightly improper operation, easily generation is out of shape and is scrapped.And new door seal, hard is partly equivalent to skeleton, is supporting overall structure, is out of shape much smaller.
Accompanying drawing explanation
Fig. 1 is refrigerator door sealing strip and mounting structure schematic diagram thereof in prior art.
Fig. 2 is the utility model and mounting structure schematic diagram thereof.
The specific embodiment
Below in conjunction with specific embodiment, the utility model is described further.Should be understood that following examples are only for the utility model is described but not for limiting scope of the present utility model.
Embodiment 1
Referring to Fig. 2, a kind of refrigerator door sealing strip that the utility model provides, comprise magnetic stripe 1, air bag 2, installation foot 3 and lip limit 4, in order to improve the fitting tight degree between installation foot 3 and door courage 5, the technical scheme of the present embodiment is that described installation foot 3 is U-shaped structure, is coated on the tongue place of a courage 5, described magnetic stripe 1, air bag 2, installation foot 3 and lip limit 4 all adopt flexible PVC material to make, and add hard PVC material 6 in the inwall of described installation foot 3.When producing, can adopt the extrusion molding mode of soft-hard coextrusion to complete.
The above is only preferred embodiment of the present utility model, and protection domain of the present utility model is also not only confined to above-described embodiment, and all technical schemes belonging under the utility model thinking all belong to protection domain of the present utility model.It should be pointed out that for those skilled in the art, in the some improvements and modifications that do not depart under the utility model principle prerequisite, these improvements and modifications also should be considered as protection domain of the present utility model.
Claims (2)
1. a refrigerator door sealing strip, comprise magnetic stripe, air bag, installation foot and lip limit, described installation foot is connected with refrigerator door liner, it is characterized in that: described installation foot is U-shaped structure, the refrigerator door liner place joining with it is tongue shape, and described installation foot is coated on the tongue place of this refrigerator door liner.
2. refrigerator door sealing strip according to claim 1, is characterized in that: described magnetic stripe, air bag, installation foot and lip limit all adopt flexible PVC material to make, and in the inwall of described installation foot, add hard PVC material.
