Abstract
The utility model discloses an aluminium and plastic combined thermal insulation door frame section. A hard plastic partition supporting section is connected in a build-in mode and foaming thermal insulation materials are filled between the upper half side of an inner aluminium section and the upper half side of an outer aluminium section. An inner wrapping iron sheet is inserted in a plastic angle section which is buckled between the end edge of the lower half side of the inner aluminium section and the end edge of the lower half side of the outer aluminium section. An electrical heating wire is inserted between the inner aluminium section and the outer aluminium section to prevent condensation. The utility model has the advantages of compact combination, simple structure, firm connection and good thermal insulation effect. The utility model is suitable for materials to manufacture door frames of large size refrigerators and large size freezers.
Description
The utility model relates to the improvement of refrigerator, freezer parts, especially a kind of plastic-aluminum composite thermal insulation doorframe, and it belongs to the freezing equipment technical field.
Commercially available refrigerator, the doorframe of freezer generally has two kinds of materials, and a kind of is plastic material, and a kind of be metal material.These two kinds of doorframes are in long-term the use, and the surface tear that has is serious, and intensity is not high, and application life is short; The cold draining that has is serious, the condensation phenomenon often occurs.
The purpose of this utility model is that a kind of thermal insulation door frame section will be provided.This section bar combines by the plastic-aluminum section bar, constitutes not only to be incubated but also anti-condensation doorframe.This section bar is simple in structure, connects firmly, and is elegant in appearance, economical and practical.
Task of the present utility model has following technical scheme to finish, developed a kind of plastic-aluminum composite thermal insulation doorframe, it comprises: aluminium extruded sections, plastic material, foaming thermal-insulating, it is characterized in that: on the inside and outside aluminium extruded sections between the half side-view build-in be connected with rigid plastics spacer section bar and be filled with foaming thermal-insulating, between second lateral ends edge of two these aluminium extruded sectionss, fasten to insert the plastics angle section of wrapping up in iron plate in being embedded with, thereby constitute the thermal insulation door frame section that cross section is the closed cavity frame.
Aluminium extruded sections in described, its cross section is " worker " font, and the last half side-view of this aluminium extruded sections is provided with two embedded fixed piece grooves, and two these grooves build-in respectively have a crossbeam of " worker " font rigid plastics spacer section bar; Be provided with inverted "L" shaped in the end edge of the following half side-view of this aluminium extruded sections and fasten card base.
Described outer aluminium extruded sections, its cross section are down " Z " font, also correspondingly on the side relative with interior aluminium extruded sections of this aluminium extruded sections are provided with two embedded fixed piece grooves, in two these grooves also respectively build-in another crossbeam of " worker " font rigid plastics spacer section bar is arranged; On the dorsal surface of this groove, be provided with oblique cutting setting-in bar groove, insert in this setting-in bar groove be embedded with cross section L-shaped in wrap up in the inclined-plane end plate of the plastics angle section of iron plate, in the pin hook plate end edge of this plastics angle section is fastened under the aluminium extruded sections on the fastening card base of the end edge of half side-view.
Described inside and outside aluminium extruded sections can be provided with the embedded slot of electrical heating wire between the side of its relative setting-in, this groove can be arranged on the end edge of outer aluminium extruded sections, the fastening card base place of aluminium extruded sections in also can being arranged on.
Thermal insulation door frame section of the present utility model, its advantage is: since adopt rigid plastics spacer section bar and in wrap up in the plastics angle section of iron plate, cold bridge between the inside and outside aluminium extruded sections is cut off, make and reduce the cold exchange between the inside and outside aluminium extruded sections as far as possible, reach heat preservation effect.Because two " worker " font rigid plastics spacer section bars are mounted in respectively in the relative embedded fixed piece groove of inside and outside aluminium extruded sections, have strengthened the mechanical strength of this assembled door frame section bar.Because the plastics angle section of " L " shape, is filled in the end edge of inserting build-in and fastening the following half side-view of inside and outside aluminium extruded sections by its pin hook plate end edge and inclined-plane end plate, make inside and outside aluminium extruded sections firm reliable in conjunction with getting.Owing to wrap up in iron plate in the plastics angle section, can attract sealing with magnetic strip of paper used for sealing on the door-plate, improve the heat insulation effect of doorframe.Owing to be provided with electrical heating wire and embedded slot thereof, can prevent that doorframe from condensing reveals frost.
Embodiment accompanying drawings of the present utility model is as follows:
Fig. 1 is the cross-sectional structure figure of plastic-aluminum composite thermal insulation doorframe.
The plastic-aluminum composite thermal insulation doorframe of making, as shown in Figure 1, on the inside and outside aluminium extruded sections 6,3 between the half side-view build-in be connected with rigid plastics (PVC) spacer 7 section bars, and be filled with foaming thermal-insulating 8.Between the end edge of the following half side-view of two these section bars 6,3, fasten to insert and wrap up in plastics (PVC) angle section 5 of iron plate in being embedded with, thereby constitute the thermal insulation door frame section that cross section is the closed cavity frame.
The interior aluminium extruded sections 6 that this doorframe is designed, its cross section are " worker " font, and the last half side-view of this aluminium extruded sections is provided with two embedded fixed piece grooves 9.In two these grooves 9 respectively build-in one crossbeam of " worker " font hardness plastics spacer 7 section bars is arranged.Be provided with inverted "L" shaped in the end edge of the following half side-view of this aluminium extruded sections 6 and fasten card base 10.For mating with interior aluminium extruded sections 6, designed outer aluminium extruded sections 3, its cross section are down " Z " font.Also correspondingly on the side relative of this section bar 3 be provided with two embedded fixed piece grooves 9 with interior aluminium extruded sections 6.In two these grooves 9 also respectively build-in another crossbeams of " worker " font rigid plastics (PVC) spacer 7 section bars is arranged.On the dorsal surface of this horizontal stroke 9, be provided with oblique cutting setting-in bar groove 11.Insert in this setting-in bar groove 11 be embedded with cross section L-shaped in wrap up in the inclined-plane end plate 14 of the plastics angle section 5 of iron plate.The pin hook plate 12 end edges of this plastics angle section 5 are fastened on the fastening card base 10 of interior aluminium extruded sections 6 end edges.Between the side of the relative inside and outside aluminium extruded sections 6,3 of setting-in, can be provided with the embedded slot 13 of electrical heating wire 4.This groove 13 can be arranged on the end edge of outer aluminium extruded sections 3, fastening card base 10 places of aluminium extruded sections 6 in also can being arranged on.Can paste intrinsic foams plastic material 2 and inserts bar 1 outside outside the long-neck wooden partition of aluminium extruded sections 3 as the external end face of this assembled door frame section bar.
