Abstract

The utility model provides a new metal door, comprising a metal door frame and a door body, which is characterized in that: a stepped section on one end of a connection block 3 which is made of metal plate with the same cross section as the door frame cross section and the whole shape size being similar to the frame section material inner chamber size is closed tightly by a metal plate, and embedded in the beam 1 of the door fame or the inner chamber on one end of the edge frame section material 2, and is fixedly connected with the door frame section material on one side opening of the door frame against the wall plane and along the opening edge by electric welding or screws, which enables the stepped section side on one end of the door frame to form a steady metal sealed side 4 and a steady metal sealed side 5, and then the beam 1 or the edge frame 2 with the connection block on one end is leaned tightly against one end of mutually perpendicular door frame section materials; the sealed side and one end of the perpendicular door frame section material are connected together rigidly by making hole, electric welding or screwing and from the opening on one side of the door frame against the wall plane. The metal door with the door frame structure has the advantages of low manufacturing cost, firmness and beautiful appearance.

Description

A kind of novel metal door

Technical field

The utility model relates to a kind of house door, particularly a kind of novel metal door.

Background technology

Metal door is as the family expenses entry door, and major function is also had home decoration and an effect attractive in appearance except that taking precautions against theft.Thereby the surface of the metal door of selling in the market, security door, steel door all is decorated with paint or other application layers.Yet the barrier propterty of this kind application layer is general, fades easily after after a while or peels off, and has a strong impact on the aesthetic of family door.Therefore, the sheet metal that has some metal door to adopt the surface to be pasted with the PVC thin-film material is now made, and the protective of this kind overlay film sheet material and ornamental better is greatly improved the durability of metal door and sight, has been subjected to users' welcome.But run into a difficult problem when using this kind overlay film sheet material processing doorframe, when being the connection employing arc welding welding between orthogonal two doorframes, can destroy the PVC thin-film material of weld, make the doorframe surface produce flaw, not only influence the antiseptic property that also reduces doorframe attractive in appearance.So the door body of some metal door product adopts precoated metal sheet material to make now, doorframe paints or sprays after then adopting the common metal plate to shape, and has avoided an above-mentioned difficult problem.But the metal door product of Gou Chenging is all not too coordinated on color, pattern and barrier propterty like this.So when having some solutions to be to use precoated metal board making doorframe recently again, the connection between its orthogonal two doorframes is adopted bolt to hang and is drawn or slotting contract degree of lip-rounding formula, has solved the problem of destroying covering material when adopting arc welding.But the interface shape complexity of this connected mode, processing difficulties, and also bonding strength and fastness are also undesirable.

The utility model content

The utility model is that a kind of novel novel metal door will be provided.Its doorframe connecting structure is not only easy to process, bonding strength is high, and can not influence the veneer film on doorframe surface.

The utility model is achieved in that the cross sectional shape of making at a sheet metal is identical with the doorframe cross sectional shape, the stepped cross-section of contiguous block one end that the monnolithic case size is similar to the doorframe inner cavity size is firmly sealed with metal sheet, and embed in the inner chamber of doorframe crossbeam or frame section bar one end, firmly be connected with doorframe with electric welding or screw along its edge at the opening part of doorframe by metope one side, make the stepped cross-section of doorframe one end form one firm metal enclosed, and then an end be equipped with the crossbeam of contiguous block or frame abut against with an end of orthogonal doorframe, from doorframe by the opening part of metope one side with punching, the form of electric welding or screw links together sealing surface and vertical gate frame section one end securely.The metal door doorframe connecting structure of this form, simple in structure, easy to process, bonding strength is high.Since pad all be in doorframe by metope or joint face inside, so can not influence the outward appearance and the veneer film on doorframe surface.Therefore the metal door manufacturing cost made from this kind sash structure is lower, and firm, attractive in appearance.

The specific embodiment

In conjunction with Fig. 1, Fig. 2, Fig. 3, Fig. 4, Fig. 5, Fig. 6, Fig. 7, Fig. 8, the cross sectional shape of making at a sheet metal is identical with doorframe crossbeam section bar 1 cross sectional shape, the stepped cross-section of contiguous block 3 one ends that the monnolithic case size is similar to doorframe crossbeam section bar 1 inner cavity size is with

metal sheet

4,5 firmly sealings, and embed in the inner chamber of doorframe crossbeam 1 one ends, the doorframe crossbeam by metope or by the opening part of ground one side along its edge or punch after 6, firmly be connected with doorframe type crossbeam 1 with electric welding, make the ladder cross section of doorframe crossbeam 1 one ends form one firm metal enclosed, and then the doorframe crossbeam 1 that an end is equipped with contiguous block abuts against with orthogonal door jamb 2 one ends, from door jamb 2 opening part punching 7, link together securely with vertical frame 2 one ends with the form of electric welding stairstepping sealing surface crossbeam 1 by hole 7 by metope one side.Certainly, the stepped cross-section shape of crossbeam 1 end and contiguous block 3 is according to the profile decision of vertical frame 2 section bars, and both can fit tightly and get final product to accomplish crossbeam 1 end and vertical frame 2 during actual fabrication.

Claims

1, a kind of novel metal door, form by metal door frame and door body, it is characterized in that: the cross sectional shape of making at a sheet metal is identical with the doorframe cross sectional shape, the stepped cross-section of contiguous block (3) one ends that the monnolithic case size is similar to the doorframe inner cavity size is firmly sealed with metal sheet, and embed in the inner chamber of doorframe crossbeam (1) or frame section bar (2) one ends, firmly be connected with doorframe with electric welding or screw along its edge at the opening part of doorframe by metope one side, make the ladder cross section of doorframe one end form metal enclosed firm (4), (5), and then an end be equipped with the crossbeam (1) of contiguous block or frame (2) abut against with an end of orthogonal doorframe, from doorframe by the opening part of metope one side with punching, the form of electric welding or screw links together sealing surface and vertical gate frame section one end securely.
