Description

Technical Field

[0001] The present application relates to the technical field of fireproof doors, and in particular to a soundproof and fireproof stainless steel door. Background Art

[0002] Fire doors are made of fireproof materials and special structural designs. They can withstand the high temperature and smoke attacks of fire for a certain period of time, and play the role of heat insulation, isolation and smoke isolation, effectively preventing the spread of fire. When a fire occurs, it can extend the time for personnel to evacuate, gain precious time for personnel to escape, and avoid being trapped in the fire.

[0003] Application No. 202022912213.5 discloses a soundproof and fireproof stainless steel door, including a telescopic rod, a pressure plate, a fireproof board, a soundproof board and soundproof cotton, etc. The soundproof board is placed between two fireproof boards, and the fireproof board is placed on the pressure plate in the stainless steel body. The connecting sleeve on the telescopic rod is rotated to extend the second threaded rod, and the pressure plate at one end is pressed tightly against the surface of the fireproof board. This soundproof and fireproof stainless steel door squeezes the pressure plate by a rotatable and extendable rod, so that the internal fireproof board and the soundproof board fit tightly, thereby enhancing the rigidity between the filler and the door body and reducing abnormal noise.

[0004] However, in use, there are the following defects:

[0005] Although telescopic rods and pressure plates are used to fit the fireproof panels and sound insulation panels together to reduce abnormal noise, they are directly connected to the stainless steel door body. When they are hit from the outside and cause dents and tilts, the telescopic rods and pressure plates will suffer from uneven force resulting in a lack of extrusion force, thereby affecting the fit of the fireproof panels and sound insulation panels. In addition, due to the lack of buffering, the telescopic rods may transmit force to the fireproof panels and sound insulation panels when hit from the outside, causing damage. Utility Model Content

[0006] The purpose of the present application is to provide a soundproof and fireproof stainless steel door, which solves the problem proposed in the background technology that a telescopic rod and a pressure plate are used to fit the fireproof board and the soundproof board together to reduce abnormal noise. However, since they are directly connected to the stainless steel door body, when they are hit from the outside and cause depression and tilt, the telescopic rod and the pressure plate will lack extrusion force due to uneven force, thereby affecting the fit of the fireproof board and the soundproof board. Moreover, due to the lack of buffering, the telescopic rod may transmit force to the fireproof board and the soundproof board when they are hit from the outside, thereby causing damage.

[0007] To achieve the above-mentioned objectives, the present application provides the following technical solutions: a soundproof and fireproof stainless steel door, comprising an outer baffle, a buffer rod, a fixed block, a mounting plate and a movable block, wherein both ends of the outer baffle are fixedly connected to the side panels, buffer rods are fixedly installed on the left and right sides of the inner wall of the outer baffle, a buffer groove is provided on the inner side of the buffer rod, and a shock absorber is fixedly installed on the inner side of the buffer groove, the shock absorber is fixedly connected to one end of a telescopic rod, and the telescopic rod is slidably connected to the inner side of the buffer groove, the other end of the telescopic rod is fixedly connected to the two sides of the surface of the sound insulation board, and fireproof panels are movably installed on both sides of the surface of the sound insulation board.

[0008] In this technical solution, the fireproof board and the sound insulation board can be fitted together by arranging a fixed block, a movable block, a No. 1 fixing bolt and a No. 2 fixing bolt. The No. 1 fixing bolt cooperates with the mounting plate to install the fixed block on the surface of the sound insulation board. The No. 2 fixing bolt cooperates with the movable block to connect the movable block, the fireproof board and the sound insulation board together, so that the fireproof board can be fitted to the surface of the sound insulation board. When the outer baffle is deformed by impact, the fireproof board and the sound insulation board can still be used normally and will not be detached due to impact, thereby improving the stability of the stainless steel door. At the same time, through the buffer rod, the telescopic rod and the shock absorber, the fireproof board and the sound insulation board can be buffered and deflected on the inner side of the stainless steel door. When the outer baffle is deformed and deflected inwardly due to impact and high temperature, the shock absorber on the inside of the buffer rod will be shortened due to the squeezing of the telescopic rod, so that the sound insulation board and the fireproof board are offset as a whole to the opposite side of the deformed outer baffle, and will not be damaged due to sudden depression and impact of the outer baffle, thereby improving the stability and practicality of the stainless steel door.

[0009] As an optional solution of the technical solution of the present application, mounting plates are fixedly connected on both sides of the outer wall of the fixing block, and a No. 1 fixing bolt is threadedly connected to the surface of the mounting plate. The No. 1 fixing bolt passes through the mounting plate and is threadedly connected to the sound insulation board below.

[0010] As an optional solution of the technical solution of the present application, sound-absorbing cotton is filled between the outer baffle and the fireproof board.

[0011] As an optional solution of the technical solution of the present application, a limiting groove is provided on the inner side of the fixed block, a spring is fixedly installed on the inner bottom of the limiting groove, and the other end of the spring is fixedly connected to the bottom of the movable block.

[0012] As an optional solution of the technical solution of the present application, No. 2 fixing bolts are threadedly connected to the left and right sides of the top surface of the movable block.

[0013] As an optional solution of the technical solution of the present application, the No. 2 fixing bolt passes through the top surface of the movable block and is threadedly connected to the fireproof board, mounting board and sound insulation board below.

[0014] Compared with the prior art, the present invention has the following beneficial effects:

[0015] 1. The present application can fit the fireproof board and the sound insulation board by setting a fixed block, a movable block, a No. 1 fixing bolt and a No. 2 fixing bolt. The No. 1 fixing bolt cooperates with the mounting plate to install the fixed block on the surface of the sound insulation board. The No. 2 fixing bolt cooperates with the movable block to connect the movable block, the fireproof board and the sound insulation board together, so that the fireproof board can be fitted to the surface of the sound insulation board. When the outer baffle is deformed by impact, the fireproof board and the sound insulation board can still be used normally and will not detach due to impact, thereby improving the stability of the stainless steel door.

[0016] 2. The present application uses a buffer rod, a telescopic rod and a shock absorber to buffer the displacement of the fireproof panel and the sound insulation panel on the inner side of the stainless steel door. When the outer baffle plate is deformed and displaced inwardly due to impact and high temperature, the shock absorber on the inner side of the buffer rod will be shortened due to the squeezing of the telescopic rod, so that the sound insulation panel and the fireproof panel will be displaced as a whole to the opposite side of the deformed outer baffle plate, and will not be damaged by sudden dents and impacts of the outer baffle plate, thereby improving the stability and practicality of the stainless steel door.
