Description
Technical Field
The utility model belongs to the door frame field.
Background
The door frame of the existing entrance door is generally made of metal materials, and the metal material door frame has the advantages of firmness and durability compared with a wooden door frame, but the metal door frame has good heat conductivity and is not beneficial to indoor heat preservation, and the frame of the existing metal door frame is integrally welded, so that the heat inside and outside the door frame is easily and rapidly transferred, and therefore, the metal door frame is not suitable for being used in regions with very low air temperature.
SUMMERY OF THE UTILITY MODEL
In view of the defect that current metal door frame exists, the utility model aims to solve the technical problem that: provides a metal door frame with better heat preservation performance.
In order to achieve the above object, according to one aspect of the present invention, the present invention is realized by the following technical measures: a metal door frame comprising: the inner frame is provided with a connecting part, the lower end of the inner frame is provided with a lower connecting part, the inner end of the upper connecting part of the inner frame is provided with a connecting plate II, the inner end of the upper connecting part of the outer frame is provided with a connecting plate I, a heat insulation plate is arranged between the connecting plate II and the connecting plate I, the connecting part on the inner frame and the connecting part on the outer frame are fixed after the connecting plate I, the heat insulation plate and the connecting plate II are passed through screws, the heat insulation plate is also arranged between the lower connecting part of the inner frame and the lower connecting part of the outer frame, and the screws pass through the lower connecting part of the outer frame, the heat insulation plate and the lower connecting part of the inner frame to fix the three.
The metal door frame is formed by splicing the inner frame and the outer frame, and the outer frame and the inner frame are connected through the heat insulation plate, so that heat can be effectively prevented from being mutually transmitted between the inner frame and the outer frame, a better heat preservation effect can be achieved indoors, and the metal door frame can be suitable for being installed and used in areas with low temperature.
Furthermore, the outer ends of the connecting parts on the inner frame and the outer frame are also provided with sealing plates, and screws penetrate through the sealing plates, the connecting plates I, the heat insulation plates and the connecting plates II to fix the connecting parts on the inner frame and the outer frame. Above-mentioned design is convenient for production and transportation, because the last connecting portion of inside casing and frame and respective connecting plate between need not to be integrative, just can make connecting portion on inside casing and the frame fixed through screw fastening reinforcing plate, connecting plate I, heat insulating board and connecting plate II after.
Compared with the prior art, the utility model has the advantages of: the metal door frame can achieve a better heat preservation effect and is suitable for being installed and used in areas with low air temperature.
