detailed description

Below in conjunction with accompanying drawing and specific embodiment the utility model is described in further detail.

Referring to Fig. 1, the utility model embodiment provides a kind of safety door that is convenient for fire escape, comprises outer door frame 1, inner door frame 2, security door body 3, inner door frame 2 is positioned at outer door frame 1, one side of outer door frame 1 Hinged with the inner door frame 2; see Figure 2, the other side of the outer door frame 1 has a reserved hole 1a; see Figure 3, the inner door frame 2 includes the inner door frame body, steel plate 2a, steel plate 2a along The facade extends to the side of the reserved hole 1a, and when the safety door is in a closed state, the steel plate 2a completely covers the reserved hole 1a;

Referring to Fig. 4, the steel plate 2a includes outwardly protruding steel columns 6, the steel columns 6 correspond to the positions of the reserved holes 1a, and the number is the same, the diameter of the steel columns 6 is smaller than the reserved holes 1a, and the steel columns 6 can pass through The reserved hole 1a passes through the outer door frame 1; as shown in Figure 5, when the safety door is in the closed state, the end of the steel column 6 is provided with a fixing piece 7 made of hot-melt material, and the diameter of the fixing piece 7 is larger than the reserved Hole 1a.

Referring to Fig. 1 and Fig. 4, the outer door frame 1 is provided with a first hinge 4, the outer door frame 1 is hinged with the inner door frame 2 through the first hinge 4, the inner door frame 2 is provided with a second hinge 5, and the inner door frame 2 passes through the second hinge 5 is hinged with the anti-theft door body 3; when the safety door is in a closed state, the outer door frame 1, the inner door frame 2, and the anti-theft door body 3 are located on the same plane.

Referring to Figure 5, the number of steel columns 6 is 1 to 3, preferably, the number of steel columns 6 is 2; the length of the steel columns 6 is greater than the depth of the reserved hole 1a; the outer door frame 1 and the inner door frame 2 A spring 8 with a diameter larger than the reserved hole 1a is arranged between them, and the spring 8 is sleeved outside the steel column 6 .

There is also a groove at the part where the outer door frame 1 is in contact with the steel plate 2a. When the safety door is in a closed state, the steel plate 2a is located in the groove, and the outer door frame 1 and the inner door frame 2 are located on the same plane.

The fixing member 7 is fixedly connected with the steel column 6 in a thermal installation manner.

The hot melt material is polypropylene or polyethylene.

The principle of the utility model embodiment is elaborated as follows:

General security door has only a door frame, and the utility model has increased a door frame, is made up of outer door frame 1, interior door frame 2 and a security door body 3. The anti-theft door body 3 is installed in the inner door frame 2 with a loose-leaf to form an anti-theft door that can be opened and closed normally. A steel plate 2a of the same size as the facade of the outer door frame 1 is installed on the inner door frame 2, and the steel plate 2a just covers the outer face of the outer door frame 1 when the door is closed. Install 1～3 steel columns 6 on the inner side of the steel plate 2a (corresponding to the outer door frame 1 side), and the length of the steel columns 6 will exceed the thickness of the outer door frame 1. At the same time, there are 1 to 3 reserved holes 1a at the positions corresponding to the steel columns 6 on the outer door frame 1. The diameter of the reserved holes 1a is slightly larger than the diameter of the steel columns 6, so that the steel columns 6 can pass through. A spring 8 is set on each steel column 6, and the diameter of the spring 8 is larger than the diameter of the reserved hole 1a of the outer door frame 1, so that the spring 8 cannot pass through the reserved hole 1a, so as to store energy. When the utility model is installed, the anti-theft door and the outer door frame 1 are closed, and the spring 8 is compressed and stored energy at the same time. The protruding part is equipped with a fixing piece 7 made of hot-melt material by means of heat installation, and the diameter of the fixing piece 7 is larger than the reserved hole 1a. Under normal temperature, hot-melt material is very firm, and steel column 6 can't withdraw, and plays the effect of anti-theft door and outer door frame 1 locking, just has restored the function of anti-theft door, still uses anti-theft door to enter and exit under the normal state.

When a fire breaks out, the indoor temperature is generally above 400°C. At high temperatures, the parts of the security door will be deformed and stuck, causing the security door to be locked and unable to be opened; since the melting point of the hot-melt material is between 100°C and 230°C Within, at this time, the fixing part 7 melts at high temperature, so the spring 8 on the steel column 6 is released, and under the elastic force of the spring 8, the whole anti-theft door will be separated from the outer door frame 1 quickly, thereby opening the door and opening the escape route .

Those skilled in the art can carry out various modifications and variations to the embodiment of the utility model, if these modifications and variations are within the scope of the claims of the utility model and equivalent technologies thereof, then these modifications and variations are also protected by the utility model within range.

The content not described in detail in the specification is the prior art known to those skilled in the art.
