Abstract

The utility model relates to an entry door, in particular to a heat insulating security door with less heat loss. The heat insulating security door is composed of a door frame and a door leaf, wherein, both the door frame and the door leaf are filled with heat insulating material, and sealing strips are arranged on a door frame contacting surface where the door frame and the door leaf are contacted; two or more sealing strips are arranged. The sealing strips are mutually connected into a whole or adopt a fission structure; the heat insulating material can be foaming polyurethane; the sealing strips can be plastic pipes with elasticity. The heat insulating security door of the utility model enhances the sealing performance of the security door through the sealing strips arranged on the door frame contacting surface of the overlapping part of the door frame and the door leaf, so as to ensure the door to be wind-proof; polyurethane foaming is performed right in the door leaf and the door frame, thus the heat transfer coefficient of the security door is reduced, and when heat is insulated, the door is simultaneously ensured not to be too thick; the structure is simple, when the functions of security and anti-theft of the entry door are ensured, both the security and the thermal insulation are simultaneously integrated organically, and two functions are performed by one door, thereby the construction cost is reduced, and the convenience is brought to householders.

Description

A kind of insulation safety door

Technical field

The utility model relates to entering house door, the insulation safety door that specifically a kind of thermal loss is few.

Background technology

For the consideration of anti-theft security, safety door is used to entering house door more and more at present.Existing safety door is considered is the safety of resident family and antitheft, does not consider heat insulation effect.The energy consumption of a building is made of five aspects, and wherein the thermal loss of entering house door accounts for 10%, can not be ignored.The energy loss of entering house door then probably is divided into two parts, and the firstth, the conductive heat loss of a body accounts for 50% of entering house door thermal loss greatly; The secondth, the ventilative loss in slit.The Coefficient K value of safety door is determined according to the energy-conservation requirement under the weather conditions of each region from kind, the thickness of self heat insulating material; And for gap loss, it is less that existing safety door is considered, because peripheral dimension is oversize, so there is the tightness in a lot of places bad, ventilative.Therefore, from the building energy conservation angle, need a thermal insulation door; And, need a safety door again from security standpoint, and so just increased cost, no matter give building side or resident family, all make troubles.

The utility model content

In order to solve the bad problem of existing safety door insulation, the purpose of this utility model is to provide a kind of insulation safety door, will be incubated and safe combining, and a door has insulation, two kinds of functions of safety.

The purpose of this utility model is achieved through the following technical solutions:

The utility model is made up of doorframe and door leaf, all is filled with heat insulating material in doorframe and the door leaf, is provided with weather strip on doorframe and the contacted doorframe contact surface of door leaf.

Wherein: weather strip is twice or more than the twice; Weather strip is connected to each other into one or for dividing body structure; Heat insulating material can be foamed polyurethane; Weather strip can be the rubber-like plastic pipe.

Advantage of the present utility model and good effect are:

1. the weather strip of the utility model by being provided with on the doorframe contact surface of doorframe and door leaf lap improved the sealing performance of safety door, makes door stuffy.

2. foam-in-place polyurethane in door leaf and doorframe reduces the thermal transmittance of safety door, and in insulation, does not make door blocked up.

3. the utility model is simple in structure, guarantee entering house door safety, antitheft in, safety will organically be combined with insulation, a door plays two effects, has reduced building costs, makes things convenient for resident family.

Description of drawings

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

Fig. 2 is the A-A sectional view of Fig. 1;

Wherein: 1 is doorframe, and 2 is door leaf, and 3 is door lock, and 4 are folding, and 5 is weather strip, and 6 is heat insulating material.

The specific embodiment

The utility model is described in further detail below in conjunction with accompanying drawing.

Shown in Fig. 1-2, the utility model is made up of doorframe 1 and door leaf 2, and door leaf 2 articulates by folding 4 and doorframe 1, and door leaf 2 is provided with door lock 3.All be filled with heat insulating material 6 in doorframe 1 and the door leaf 2, in order not make door blocked up, present embodiment foam-in-place polyurethane, thickness are 40mm, then Coefficient K=0.79w/m ²K.Doorframe 1 has the wide contact surface of 25mm with the door leaf 2 contacted positions that compress, and is provided with twice or the weather strip more than the twice 5 on the doorframe contact surface, and the weather strip of present embodiment is twice, is diameter phi 10mm, rubber-like plastic pipe.Weather strip 5 is connected to each other and is one also to can be the branch body structure.When the closed safe door, door leaf 2 is pressed on the weather strip 5, when guaranteeing that safety door is antitheft, safe, has improved the sealing performance of door, makes the energy loss of entering house door drop to minimum.Even door leaf 2 and doorframe 1 are incomplete when parallel,, also can guarantee sealed air-tight because the elasticity of weather strip 5 changes.
