Abstract

The utility model relates to a metal door, which is composed of front and rear panels, left and right side bars, upper and lower end bars, and foaming stocks injected at the middle. Both side edges of the front and the rear panels are relatively bended inward into a U-shaped folding. Both side edges of the left and the right side bars are relatively bended outward into a U-shaped folding. The front and the rear panels and the left and the right side bars are mutually inserted into a box shape. Upper and lower sealing edges of the front and the rear panels are relatively folded into an S-shaped inserting slot. The upper and the lower end bars are relatively bended into an N-shaped folding. The upper and the lower end bars are inserted on upper and lower end faces composed of the front and the rear panels and the left and the right side bars. The utility model has the advantages that the panels are convenient to be combined and assembled and are firmly inserted, the working size of a door can be changed optionally according to needs, etc.

Description

Metal family door

The utility model relates to a kind of metal family door, particularly a kind of metal family door that integrates antitheft, insulation, sound insulation.

Existing metal family door, the front and back panels of door is stamping forming metal sheet roof covering, and the panel both sides are through flanging welding or chimeric mutually relatively, and the foamed material combination forming is injected in the centre.Its defective is: at first, deform, and rugged welding scar and ablated surface phenomenon obviously arranged at weld, must be after repairing japanning resilient; Secondly, the panel processing dimension can not flexible transformation, corresponding one pair of processing mold of family door that can only a kind of specification, and interchangeability is relatively poor.

The purpose of this utility model be to provide a kind of panel sets attach together prescription just, chimeric firm, metal family door that family door processing dimension can arbitrarily change as required.

The purpose of this utility model is achieved like this, a kind of metal family door, form by front and back panels 1,2, left and right side slat 4,5, upper and lower end bar 6,7, the middle foamed material 3 that injects, the dual-side of described front and back panels 1,2 all inwardly relatively is bent into " ∪ " shape flanging 8, the dual-side of left and right side slat 4,5 all outwards relatively is folded into " ∪ " shape flanging 9, and front and back panels 1,2 becomes box-like with left and right side slat 4,5 mutual embeddings; The upper and lower edge sealing of described front and back panels 1,2 all relatively is folded into the caulking groove 10 of serpentine, upper and lower end bar 6,7 relatively is bent into " ∏ " shape flanging 11, and upper and lower end bar 6,7 is entrenched on the upper and lower end face of front and back panels 1,2 and left and right side slat 4,5 compositions.

Below in conjunction with accompanying drawing the utility model is further described below.

Fig. 1 is a front view of the present utility model.

Fig. 2 is a vertical view of the present utility model.

Fig. 3 is the A-A sectional view of the utility model Fig. 1.

Fig. 5 is B '-B ' sectional view of the utility model Fig. 1.

Fig. 6 is the C-C sectional view of the utility model Fig. 2.

Front and back panels 1,2 of the present utility model is passed through the beading moulding with the chromatic metallic thin plate, the dual-side of front and back panels 1,2 all bends inwards the flanging 8 of " ∪ " shape, left and right side slat 4,5 can select for use the metal sheet roof covering that matches with front and back panels 1,2 colors to make, with all folded-out one-tenth of the dual-side of left and right side slat 4,5 " ∪ " shape flanging 9, when inside " ∪ " shape flanging 8 of current, rear board 1,2 both sides and outside " ∪ " shape flanging of left and right side slat 4,5 both sides 9 are chimeric, finish being connected of front and back panels 1,2 and left and right side slat 4,5.Upper and lower end bar 6,7 of the present utility model can select for use metal sheet roof covering to be made equally, " ∏ " shape flanging 11 will be bent into around the upper and lower end bar 6,7, upper and lower two edge sealing of front and back panels 1,2 are folded into serpentine caulking groove 10, when the flanging 11 of upper and lower end bar 6,7 both sides cooperates with the caulking groove 10 of front and back panels two edge sealing about in the of 1,2, finish cooperating of upper and lower end bar 6,7 and front and back panels 1,2, and two side edgefolds 11 in addition of upper and lower end bar 6,7 are fitted with the upper and lower end face of left and right side slat 4,5.The last foamed material 3 that in the box-like family door that is assembled into by front and back panels 1,2, left and right side slat 4,5, upper and lower end bar 6,7, injects.

The utility model is because after adopting said structure, need not any securing member, just can easily panel, side slat, end bar be assembled into the family door, avoided the appearance of welding deformation and door surface soldered scar, ablation phenomen, have easy for installation, the door surface is complete, good decorating effect, integrate antitheft, insulation, sound insulation; Simultaneously, can cut randomly length, the height, wide of family door, not be subjected to the restriction of processing mold, have advantages such as interchangeability is good according to user's needs.
