Abstract
The utility model discloses a soft and rigid co-extruded door seal, wherein one side of a connecting piece of the door seal is a del insert as a root, and the other side of the connecting piece is connected with a seal strip. The soft and rigid co-extruded door seal is characterized in that the hardness of the materials of the connecting piece and the del insert is more than that of the material of the seal strip. According to utility model, the soft and rigid co-extruded door seal can be installed firmly, is not easy to deform, and can ensure the use effect.
Description
Technical field
The utility model relates to an envelope, more particularly especially uses the door envelope that makes refrigerator doors and refrigeratory body obtain excellent sealing in the refrigerator.
Background technology
In prior art, the version of refrigerator doors envelope is that a side of brace is the inverted triangle inserts as root, and opposite side is a strip of paper used for sealing, and the inverted triangle inserts is used for the door envelope is inlaid in the draw-in groove of a courage, and strip of paper used for sealing is used between refrigerator doors and refrigeratory body, forming sealing.It is the whole flexible PVC material extrusion molding of adopting that the refrigerator doors of this version is enclosed in the prior art; Hardness is (70 ± 1) HS (A); The door courage is a hard HIPS material, is to embed in the draw-in groove of door courage through the inverted triangle inserts that knocking of opposite house envelope sealed up door when assembling.Mainly there is following problem in this existing structure form: the one, because door envelope is a soft material, the inverted triangle inserts of its root possibly be out of shape and causes an envelope to come off in case too hot or install badly because of environment; The 2nd, because an envelope is the flexible PVC material, the length of door envelope can obviously change by Yin Wendu, and when the environment temperature rising, the door envelope then can be elongated because of expansion, causes surface wrinkling, influences result of use.
Summary of the invention
The utility model is for avoiding above-mentioned existing in prior technology weak point, provide a kind of installation firm, not yielding, can guaranteeing the soft-hard coextrusion door envelope of result of use.
The utility model technical solution problem adopts following technical scheme:
The version of the utility model soft-hard coextrusion door envelope is: the side at brace is the inverted triangle inserts as root, and opposite side is a strip of paper used for sealing; Its design feature is: select the material hardness of the material hardness of brace and inverted triangle inserts greater than strip of paper used for sealing.
Said brace, inverted triangle inserts and strip of paper used for sealing are with different hardness material coextrusion mold.
The hardness of said brace and inverted triangle inserts is 85-95HS (A), and the hardness of said strip of paper used for sealing is 65-75HS (A).
Compared with present technology, the utility model beneficial effect is embodied in:
1, brace and inverted triangle inserts adopt the material of relative hard in the utility model, can guarantee effectively that refrigerator can not come off in its rational environment for use;
2, in the utility model, because brace and inverted triangle inserts hardness improve relatively, the relative quantity of expanding with heat and contract with cold reduces, and the elongation under the high temperature is unlikely to surface wrinkling, has effectively guaranteed result of use.
Description of drawings
Fig. 1 is the utility model structural representation;
Label among the figure: 1a brace; 1b inverted triangle inserts; The 1c strip of paper used for sealing; 2 courages.
The specific embodiment
Referring to Fig. 1; Soft-hard coextrusion door envelope is identical with prior art in the present embodiment is that a side at its brace 1a is the inverted triangle inserts 1b as root; That opposite side connects is strip of paper used for sealing 1c; Inverted triangle inserts 1b is used for the door envelope is inlaid in the draw-in groove of a courage 2, and strip of paper used for sealing 1c is used between refrigerator doors and refrigeratory body, forming sealing.
In the present embodiment, select the material hardness of the material hardness of brace 1a and inverted triangle inserts 1b greater than strip of paper used for sealing 1c.
In the practical implementation; The hardness of brace 1a and inverted triangle inserts 1b is 85-95HS (A); The hardness of strip of paper used for sealing 1c is 65-75HS (A), and the strip of paper used for sealing 1c of brace 1a and inverted triangle inserts 1b and different hardness material is with different hardness material coextrusion mold, and the door closure material is not limited to PVC.
During installation, be that the inverted triangle inserts 1b that door is sealed up is inlaid in the draw-in groove of a courage 2 equally, operable erecting tools is pneumatic hammer or rubber hammer.
Claims (3)
