Description

Technical Field

[0001] This utility model relates to the field of fire door impact protection, specifically a fire door with impact buffering function. Background Technology

[0002] A fire door with impact-resistant function disclosed in Chinese Utility Model Patent Application Publication CN 216714253 U includes a door panel with a telescopic groove on its surface. A buffer plate is installed inside the telescopic groove, and a limit strip is provided on the surface of the buffer plate. The limit strip is slidably connected in a slide groove, which is located on the surface of the telescopic groove. A pulley is provided on the surface of the limit strip. A through hole is provided on the surface of the buffer plate, and a guide post is inserted into the through hole. The guide post is fixed to the surface of the telescopic groove, and a baffle is provided at the end of the guide post. A spring is sleeved on the outside of the guide post. The beneficial effects are: the fire door with impact-resistant function proposed in this utility model has telescopic grooves on both sides to install buffer plates. A spring is added between the buffer plate and the telescopic groove. When the surface of the buffer plate is impacted, the spring is compressed to buffer the impact. Furthermore, limit strips are added to the top and bottom surfaces of the buffer plate, allowing it to slide along the slide groove, preventing the buffer plate from swinging or tilting.

[0003] Installing buffer plates and springs inside fire doors weakens their structural strength. Upon impact, the fire door is highly likely to break directly, resulting in shattering and loss of fire resistance. Therefore, a fire door with impact buffer function is proposed to address this issue. Utility Model Content

[0004] The purpose of this invention is to provide a fire door with impact buffering function to solve the problem mentioned in the background art that the buffer plate and spring will weaken the structural strength of the protective door.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A fire door with impact buffer function includes a fire door, a telescopic rod, and a buffer wall. A rotating frame is fixedly installed on the right side of the fire door, and a telescopic rod is rotatably installed inside the rotating frame. The other end of the telescopic rod is rotatably installed on the left side of the buffer wall. A first spring is sleeved on the outside of the telescopic rod. A buckle is fixedly installed on the lower left side of the buffer wall. A guide block is fixedly installed on the lower right side of the fire door, and a positioning pin slides through the guide block.

[0024] Please see Figures 1-4 As shown, this utility model provides a technical solution:

[0025] A fire door with impact buffer function includes a fire door 1, a telescopic rod 3, and a buffer wall 5. A rotating frame 2 is fixedly installed on the right side of the fire door 1. The telescopic rod 3 is rotatably installed inside the rotating frame 2. The other end of the telescopic rod 3 is rotatably installed on the left side of the buffer wall 5. A first spring 4 is sleeved on the outside of the telescopic rod 3. A buckle 7 is fixedly installed on the lower left side of the buffer wall 5. A guide block 8 is fixedly installed on the lower right side of the fire door 1. A positioning pin 9 slides through the inside of the guide block 8. The telescopic rod 3, together with the first spring 4, buffers the impact of the buffer wall 5 to prevent the buffer wall 8 from being subjected to excessive pressure and breaking directly. The additional guide block 8 is connected to the positioning pin 9 and inserted into the buckle 7 of the buffer wall 8 for connection and to house and fix the buffer wall 8.

[0026] The surface of the buffer wall 5 is covered with a rubber layer. The buffer wall 5 is made of foam composite board, which facilitates the foam composite board and the outer rubber layer to enhance the buffer performance of the buffer wall 5. The bottom end of the buffer wall 5 is evenly provided with rotating grooves. The rotating grooves of the buffer wall 5 are equipped with pulleys 6, which facilitate the movement of the buffer wall 5 through the pulleys 6 inside the bottom rotating grooves, further reducing the impact. The positioning pins 9 are symmetrically arranged on the right side of the fire door 1. One end of the positioning pin 9 is fixedly provided with a pull plate 10, which facilitates pulling the pull plate 10 to push the positioning pin 9 into the inside of the buckle 7 for assembly.

[0027] A fixing block 11 is fixedly installed on the upper right side of the fire door 1. A transmission plate 12 is rotatably installed on the right side of the fixing block 11. A lifting frame 13 is rotatably installed on the top of the transmission plate 12. A buffer block 16 is fixedly installed on the left side of the lifting frame 13. A sliding groove is opened inside the lifting frame 13. A vertical shaft 14 is slidably installed inside the lifting frame 13. The bottom end of the vertical shaft 14 is fixedly connected to the fixing block 11. A second spring 15 is sleeved on the outside of the vertical shaft 14. The two ends of the second spring 15 are respectively connected to the lifting frame 13 and the fixing block 11. The added fixing block 11 positions and supports the lifting frame 13. After being impacted, it moves downward, compressing and deforming the second spring 15 on the outside of the vertical shaft 14, preventing the fire door 1 from closing quickly and generating large vibrations.

[0028] In this embodiment, a fire door with impact buffer function is used by the operator who assembles the buffer wall 5 into the rotating frame 2 of the fire door 1 via the telescopic rod 3. When selecting the buffer wall 5 for use, the operator rotates the buffer wall 5 to fit against the right side of the fire door 1, and then fits the buckle 7 on the left side of the buffer wall 5 against the right side of the fire door 1. The operator then pushes the pull plate 10 to insert the positioning pin 9 into the buckle 7, maintaining the buffer wall 5 against the right side of the fire door 1. If a better buffering effect is needed, the positioning pin 9 is pulled out from the buckle 7, and the bottom end of the buffer wall 5 is... When the pulley 6 is placed on the ground, the buffer wall 5 is impacted, which pushes the first spring 4 on the outside of the telescopic rod 3 to compress and deform, thereby providing a stronger buffering effect. This also avoids the situation where too many structures are added inside the fire door 1, which would reduce the structural strength. During the closing process of the fire door 1, the buffer block 16 above the fixed block 11 first adheres to the wall surface, pushes the lifting rod 13 to move on the outside of the vertical shaft 14, pushes the transmission plate 12 to rotate, and squeezes the second spring 15 on the outside of the vertical shaft 14 to compress and deform, thereby strengthening the buffering effect, protecting the fire door 1 and reducing vibration.

[0029] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
