Detailed Description

The technical solutions in the embodiments of the present invention will be described clearly and completely with reference to the accompanying drawings of the embodiments of the present invention, and it is obvious that the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments in the present invention, all other embodiments obtained by a person skilled in the art without creative efforts belong to the protection scope of the present invention.

The embodiment is basically as shown in the attached figure 1: the utility model provides a fire door is prevented to novel steel of environmental protection material preparation, includes door frame 1 and two steel prevent fire door 2, and two steel prevent fire door 2 and all rotate and install on door frame 1, and the steel prevents fire door 2 and goes up fixed mounting has four rotation strips 4, lies in to rotate through two joint bars 6 between two rotation strips 4 with one side and installs same install bin 3, and install bin 3 fixed mounting is on door frame 1.

In this embodiment, as shown in fig. 2, when the fire door made of steel 2 needs to be removed, the locking of the pressing rod 14 is firstly released, because the two springs 13 are in a compressed state before the pressing rod 14 is released, after the locking of the pressing rod 14 is released, the two springs 13 contract to drive the same extrusion plate 7 to move, the extrusion plate 7 horizontally slides on the two sliding rods 12 through the two sliding holes 11, so that the extrusion plate 7 is limited to only horizontally move, meanwhile, the extrusion plate 7 moves to drive the two rotation rods 8 to move through the two rotation shafts 10, the two rotation rods 8 drive the two clamping rods 6 to move through the other two rotation shafts 10, in this process, the rotation rods 8 rotate on the two rotation shafts 10 through the two rotation holes 9, so that the two clamping rods 6 are separated from the two clamping grooves 21, so that the two rotation strips 4 can be separated from the installation box 3, and the fire door made of steel 2 can be separated from the door frame 1, thereby facilitating the removal of the fire door made of steel 2.

In this embodiment, as shown in fig. 3, when the lock of the pressing rod 14 needs to be released, the handle 20 may be rotated, so that the pressing rod 14 is rotated by the handle 20, the pressing rod 14 rotates in the circular rotating groove 18 through the circular rotating block 19, and the pressing rod 14 is restricted to rotate only.

In this embodiment, as shown in fig. 4, after the top pressure rod 14 is unlocked, the two springs 13 drive the same extrusion plate 7 to move, so that the extrusion plate 7 drives the two clamping rods 6 to move through the two rotating rods 8, so that the two clamping rods 6 are separated from the two clamping grooves 21, and thus the two rotating strips 4 can be separated from the installation box 3.

In this embodiment, as shown in fig. 5, when the handle 20 is rotated to rotate the knock bar 14, the bar 16 is rotated until the position of the bar 16 corresponds to the position of the bar hole 15, and at this time, the knock bar 14 can be unlocked.

The specific implementation is as follows:

when the fire door made of steel 2 needs to be dismantled, four handles 20 can be rotated at a time, so that the handles 20 drive the jacking rod 14 to rotate, the jacking rod 14 rotates in the circular rotating groove 18 through the circular rotating block 19, and further the position of the strip-shaped block 16 corresponds to the position of the strip-shaped hole 15, because the two springs 13 are in a compressed state, the extrusion plate 7 moves to one side close to the strip-shaped hole 15 under the driving of the two springs 13, the extrusion plate 7 moves to horizontally move on the two sliding rods 12 through the two sliding holes 11, and further the extrusion plate 7 moves to drive the two rotating rods 8 to move, the two rotating rods 8 move to drive the two clamping rods 6 to move, and further the two clamping rods 6 are separated from the two clamping grooves 21, at the moment, the fire door made of steel 2 can be separated from the door frame 1, and therefore the fire door made of steel 2 can be dismantled quickly and conveniently, therefore, trapped people can quickly escape, and meanwhile, the installation box 3 is installed on one side close to the refuge room and is prevented from being burnt by fire, so that the installation box is not easy to deform and damage.

The foregoing has described in detail preferred embodiments of the present invention. It should be understood that numerous modifications and variations can be devised by those skilled in the art in light of the teachings of the present invention without undue experimentation. Therefore, the technical solutions that can be obtained by a person skilled in the art through logic analysis, reasoning or limited experiments based on the prior art according to the concepts of the present invention should be within the scope of protection defined by the claims.
