The metal door frame also comprises the fastener. The fastener is inserted in the inserted clamping groove of the secondary main frame and the primary main frame and fixed with the secondary main frame and the primary main frame by screws or pulling nails. As the secondary main frame and the primary main frame are assembled at the angle of 45 DEG and fixed by the fastener, the utility model has the advantages of hardness, firmness, simple assembly, no need of weld joint, no transport difficulty caused by large volume of a welded metal door frame, no damage on the surface of a steel plate, and high beauty.
Description
Technical field
The utility model relates to a kind of metal door frame, particularly a kind of metal door frame of miter angle package assembly.
Background technology
Metal door frame in the market all adopts the mode of production of welding again after the doorframe moulding.Metal door frame volume after the welding is big, easily causes too much freight; Use PVC to cover plastic-steel plate or the good steel plate production doorframe of surface spraying in addition, can damage surface of steel plate after the welding, influence the appearance effect of doorframe.
Summary of the invention
It is big that the utility model is intended to overcome the prior art volume, the freight height, and the inaesthetic weak point of external form provides a kind of welding and metal door frame aesthetic in appearance of need not.
To achieve these goals, metal door frame of the present utility model is by the main frame of mother, and sub main frame and securing member constitute, and securing member is inserted in the peg graft good female main frame and sub main frame.
Female main frame, sub main frame end are corresponding mutually miter angle.
Female main frame, sub main frame are respectively equipped with mortise, the tenon that is used to peg graft, and both sides also are provided with the draw-in groove that is used to install securing member.
Securing member is inserted in the draw-in groove of peg graft good female main frame and sub main frame, and fixes with screw or blind rivet and female main frame and sub main frame.
Advantage of the present utility model: owing to female main frame, sub main frame are the miter angle assembling, and fix with securing member, solid firm, and assembling is simple, need not welding, the transportation difficulty of having avoided welding back metal door frame volume to cause greatly, and can not damage surface of steel plate, aesthetic property is improved greatly.
Below in conjunction with accompanying drawing the utility model is described in detail.
