[0002] A fire door is a door that meets the requirements of fire resistance, stability, integrity and thermal insulation within a certain period of time. It is a fire-resistant partition with a certain fire resistance installed between fire compartments, evacuation stairwells, vertical shafts, etc. In addition to the functions of ordinary doors, fire doors can also prevent the spread of fire and smoke. They can prevent the spread of fire within a certain period of time and ensure the evacuation of personnel.
[0003] According to the public patent 202321361569.1, a fire door that prevents deformation and jamming includes a door frame, and both sides of the door frame are rotatably provided with fire door panels through hinges, an observation window is provided on the upper part of the front side of the fire door panel, and the interior of the observation window is fixedly connected with fireproof glass, and an anti-jamming mechanism is provided between the two fire door panels, and a water storage tank is fixedly connected to the top of the front side of the door frame, and the bottom of the water storage tank is connected with a plurality of drain pipes. In the process of realizing the utility model, the inventor found that at least the following problems in the prior art have not been solved. The observation window and the fireproof glass facilitate the staff to solve the problem of not being able to observe the specific conditions of the fire behind the fire door in advance before prying the fire door panel. During use, the traditional fire door is easily deformed by being directly squeezed by the wall, and the first fire door body and the second fire door body are easily stuck when opened, which improves the flexibility of the fire door during use. To this end, it is necessary to design a new technical solution to solve it. Utility Model Content
[0004] The purpose of the utility model is to overcome the deficiencies of the prior art, meet actual needs, and provide a fire door that prevents deformation and jamming, so as to solve the technical problems that the current wall directly generates squeezing force on the fire door, causing it to be compressed and deformed, and the first fire door body and the second fire door body to be stuck when opening.
[0005] In order to achieve the purpose of the utility model, the technical solution adopted by the utility model is: to design a fire door that is resistant to deformation and jamming, including a door frame, the four sides of the door frame are connected with mounting columns through limiting grooves, the other end of the mounting column is connected with an adjusting stud through a sleeve column, the other end of the adjusting stud is connected to an anti-deformation frame through a limiting nut, and a buried groove is opened on the periphery of the anti-deformation frame.
[0006] Preferably, the two sides of the door frame are respectively connected with a first fireproof door body and a second fireproof door body through hinges, and the second fireproof door body is installed with a fireproof transparent glass window.
[0007] Preferably, both ends of the first fireproof door body and the second fireproof door body are connected with a rolling ball through a mounting groove, both ends of the rolling ball are movably connected to the inner wall of the mounting groove, and 4 / 5 of the rolling ball is located inside the mounting groove.
[0008] Preferably, one end of the mounting column is matched with the size of the limiting groove and is rotatably connected to its inner wall, and one end of the sleeve column is fixedly connected to the other end of the mounting column and is movably connected to the outer surface of the door frame.
[0009] Preferably, one end of the adjusting stud is connected to the inside of the other end of the sleeve through a thread, and the other end of the adjusting stud passes through the inside of the anti-deformation frame and is evenly distributed inside the buried groove.
[0010] Preferably, the limiting nut is fixedly mounted inside the buried groove and is connected to the other end of the adjusting stud via a thread.
[0011] Compared with the prior art, the beneficial effects of the present invention are:
[0012] The utility model combines the limit groove, the installation column, the sleeve column, the adjustment stud, the limit nut, the anti-deformation frame and the buried groove. When the fire door is installed, the anti-deformation frame is first installed on the wall. When the wall sinks, the wall will generate a squeezing force on the anti-deformation frame, thereby avoiding the phenomenon that the wall directly generates a squeezing force on the fire door and causes the fire door to be compressed and deformed.
[0013] Then place the door frame inside the anti-deformation frame, and then pass the adjusting stud through the anti-deformation frame and screw it into the corresponding adjusting nut. During this process, the sleeve column will drive the installation column to rotate inside the limit groove, so as to adjust the installation position of the door frame inside the anti-deformation frame, thereby improving the convenience of the fire door during installation and fixing, and allowing the fire door to be adjusted during the installation process to prevent the fire door from deviating from its position after installation.
[0014] When the first fire door body and the second fire door body are opened from the door frame, the top and bottom ends of the first fire door body and the second fire door body will slide on the door frame through the balls. During this process, the balls will rotate inside the mounting grooves to prevent the first fire door body and the second fire door body from getting stuck when opening.
