Description

Technical Field

[0001] This utility model relates to the field of indoor decoration fire prevention equipment, specifically an indoor decoration fire prevention device. Background Technology

[0002] In today's interior design industry, fire safety is of paramount importance. With the continuous development of building technology and people's increasing demands for the safety of their living and working environments, fire prevention devices in interior decoration have become a key element in protecting life and property.

[0003] Existing indoor fire protection devices, such as traditional fire doors and fire-resistant roller shutters, while possessing certain fire protection functions, have many limitations. Fire doors are inconvenient to open and close; in emergencies, personnel may panic and be unable to operate them correctly in a timely manner, affecting evacuation efficiency. Furthermore, the installation location of fire doors is relatively fixed, making them inflexible for different indoor space layouts.

[0004] Common fire-resistant roller shutters are typically made of metal, are large in size, and complex to install, requiring a significant amount of space. During operation, they are susceptible to problems such as track jamming and motor malfunctions, which can prevent them from descending properly in the event of a fire, delaying fire prevention efforts. Furthermore, traditional fire-resistant roller shutters rely solely on their physical barrier properties for fire protection, offering limited capabilities in cooling and fire extinguishing. Utility Model Content

[0005] In view of the problems in the prior art, this utility model provides an indoor fire prevention device.

[0006] The technical solution adopted by this utility model to solve its technical problem is: an indoor decoration fire prevention device, including threaded ends, the number of threaded ends is two, the threaded ends of the two threaded ends are connected to the outer tubes, a telescopic rod is inserted into the inner tubes, a compression spring is installed between the blind end of the telescopic rod and the threaded end, a sleeve is installed at the center of the inner end face of the two threaded ends, a shaft is inserted between the two sleeves, and a torsion spring is installed at the connection between the shaft and the sleeve. A protective tube is installed concentrically on the outer side of the shaft. Both ends of the protective tube are fixedly installed on the inner end face of the threaded end. A rectangular hole is opened at the bottom of the protective tube. Fireproof curtains are wrapped around the outer side of the shaft, and multiple fireproof curtains are distributed at equal intervals along the shaft axis. The fireproof curtain is made of two layers of fireproof cloth heat-sealed together, with a cavity reserved between the two layers of fireproof cloth. Flame retardant is injected into the cavity. The bottom of the fireproof curtain is connected to a positioning tube, and the diameter of the positioning tube is larger than the width of the rectangular hole.

[0007] Specifically, a first flow channel is provided between the two layers of fireproof cloth, and the two adjacent cavities are connected through the first flow channel. A second flow channel is provided at the top of the fireproof cloth. The shaft is a hollow tube structure component, and both ends of the shaft are sealed by circular plates. A through hole is provided at the bottom of the shaft where it connects with the fireproof curtain, and the through hole is connected to the second flow channel. A sealing plug is installed on the upper part of the outer wall of the shaft.

[0008] Specifically, the shaft has a partition installed inside, which divides the internal area of ​​the shaft into several cavities, and each cavity corresponds independently to a fireproof curtain.

[0009] Specifically, magnets are embedded between the two layers of fireproof fabric, with the magnets symmetrically distributed on both sides of the fireproof curtain, and adjacent fireproof curtains are positioned by magnetic attraction.

[0010] Specifically, a positioning rope is installed inside the cavity. The positioning rope is adhered to the inner wall of the fireproof cloth, and the positioning rope is a component made of a fire-resistant metal material.

[0011] Specifically, the end face of the telescopic rod is provided with a placement groove, and a silicone pad is installed in the placement groove.

[0012] Specifically, a rope is connected inside the positioning tube, and counterweights are installed at both ends of the rope.

[0013] The beneficial effects of this utility model are: This utility model discloses an indoor fire prevention device. It employs a telescopic rod with springs at both ends for installation on a door frame, making installation simple and quick. It can flexibly adapt to various door frames and different interior area sizes, greatly improving the versatility and convenience of installation. The fireproof cloth rolled around the outside of the telescopic rod contains a water-filled cavity. In the event of a fire, the fireproof cloth separates from the rod and forms a water curtain. This not only physically blocks fire and smoke like traditional fire prevention devices but also utilizes the cooling properties of water to effectively lower the surrounding temperature and slow the spread of fire. Furthermore, the curtain-like design of this device does not occupy extra space and will not affect normal passage or space utilization inside the room during non-fire conditions. This utility model discloses an indoor fireproof device. When the device needs to be disassembled after use, the flame retardant can be pushed back into the shaft by squeezing from the bottom of the fireproof cloth. This effectively reduces the outer diameter of the fireproof cloth when it is rolled up, thus reducing the overall size of the device. The device can also be inverted during rolling, and the fireproof cloth can be rolled up to the outside of the shaft under the elastic force of the torsion spring. A partition is installed inside the shaft, dividing the internal area into several cavities. Each cavity independently corresponds to a fireproof curtain, meaning the flame retardant in each fireproof curtain is stored in a separate cavity, ensuring consistent flame retardant content and fireproof effect. A positioning rope is installed inside the cavity. The positioning rope, made of fire-resistant metal, increases the overall fire resistance of the fireproof cloth. Simultaneously, the positioning rope limits the inner side of the cavity, ensuring consistent expansion space within the cavity, further guaranteeing consistent flame retardant content in each cavity from bottom to top.

[0016] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0017] Furthermore, the terms used below are defined based on the functions of this utility model and may vary depending on the user's or operator's intent or convention. Therefore, these terms are defined based on the entire contents of this specification.

[0018] See Figure 1-4 The present invention discloses an indoor fire prevention device, comprising two threaded ends 1. Each threaded end 1 is connected to an outer tube 2. A telescopic rod 3 is inserted inside the outer tube 2. A compression spring 4 is installed between the blind end of the telescopic rod 3 and the threaded end 1. A sleeve 11 is installed at the center of the inner end face of each threaded end 1. A shaft 5 is inserted between the two sleeves 11. The threaded end 1, outer tube 2, telescopic rod 3, compression spring 4, sleeve 11 and shaft 5 constitute a basic positioning component. This basic positioning component can be fixed in the indoor door frame, the walls on both sides of the indoor passageway, etc. In this embodiment, it is illustrated by installation in the door frame. The outer tube 2 is fixed to the threaded end 1 by a threaded connection. When the outer tube 2 is rotated, its elongation relative to the threaded end 1 changes, that is, the overall length of the above-mentioned basic positioning component changes, so as to be suitable for use with door frames of different widths. In the actual adjustment process, it is necessary to ensure that the overall length of the above-mentioned basic positioning component is greater than the width of the door frame. Therefore, when installing and fixing the above-mentioned basic positioning components, firstly, press the end face of one end of the telescopic rod 3 against the inner wall of one side of the door frame, press the other end of the telescopic rod 3 so that it retracts relative to the outer tube 2 and compresses the compression spring 4 to have a rebound force, and then move the telescopic rod 3 to the inner wall of the other side of the door frame, and try to ensure that the end faces of the two telescopic rods 3 are perpendicular to the inner wall of the door frame. At this time, the elastic force of the two compression springs 4 fixes the above-mentioned basic positioning components to the inner side of the door frame. A protective tube 6 is provided at a concentric position on the outer side of the shaft 5. Both ends of the protective tube 6 are fixedly installed on the inner end face of the threaded end 1. A rectangular hole 61 is opened at the bottom of the protective tube 6. A fireproof curtain 7 is wound around the outer side of the shaft 5, and multiple fireproof curtains 7 are distributed at equal intervals along the axis of the shaft 5. The telescopic rod 3 has a placement groove 31 on its end face, and a silicone pad 32 is installed in the placement groove 31. Based on the above, the silicone pad 32 acts directly on the inner side of the door frame. During the installation of the basic positioning component, the silicone pad 32 is squeezed and its surface deforms. When the inner side of the door frame is not uneven, the deformation of the silicone pad 32 can increase the contact area with the inner side of the door frame, and the friction between the two increases, making the installation of the basic positioning component more secure. like Figures 1-2As shown, the fire curtain 7 is made of two layers of fireproof cloth 71 heat-sealed together, with a cavity 72 reserved between the two layers of fireproof cloth 71. Flame retardant is filled into the cavity 72. The bottom of the fire curtain 7 is connected to a positioning tube 8, and the diameter of the positioning tube 8 is larger than the width of the rectangular hole 61. Under normal conditions, multiple fire curtains 7 are wound around the outside of the shaft 5. The positioning tube 8 limits the movement of the fire curtains 7 to prevent them from being completely retracted inside the protective tube 6. When fire protection is required, the positioning tube 8 is pulled to move the fire curtains 7. The fire curtain 7 is separated from the shaft 5. A torsion spring is installed at the connection between the shaft 5 and the sleeve 11. The rotation of the shaft 5 causes the torsion spring to compress. Generally, the weight of the fire curtain 7, flame retardant, and positioning tube 8 is greater than the elastic force of the torsion spring. When multiple fire curtains 7 are in the unrolled state, a fire-resistant water curtain can be formed at the door frame. It not only plays the role of physically blocking fire and smoke like traditional fire prevention devices, but also utilizes the cooling properties of the flame retardant to effectively reduce the surrounding temperature and slow down the spread of fire. At the same time, the design of this device, similar to a door curtain, does not occupy extra space and will not affect normal passage and space utilization inside the room in non-fire conditions.

[0019] See Figures 1-4 A first flow channel 73 is provided between the two layers of fireproof cloth 71, and the two adjacent cavities 72 are connected through the first flow channel 73. A second flow channel 74 is provided at the top of the fireproof cloth 71. The shaft 5 is a hollow tube structure component, and both ends of the shaft 5 are sealed by circular plates. A through hole 51 is provided at the bottom of the shaft 5 where it connects with the fireproof curtain 7, and the through hole 51 is connected to the second flow channel 74. A sealing plug is installed on the upper part of the outer wall of the shaft 5. Under normal conditions, the flame retardant is stored inside the shaft 5. When several fireproof cloths 71 are separated from the shaft 5, the second flow channel 74 is creased. The through hole 51, the second flow channel 74, the cavity 72 and the first flow channel 73 are connected to each other. The flame retardant liquid enters each cavity 72 in sequence under the action of gravity. When this utility model is finished and needs to be disassembled, the flame retardant can be pushed back into the shaft 5 by squeezing (or inverting) the bottom of the fireproof cloth 71. This effectively reduces the outer diameter of the fireproof cloth 71 when it is rolled up, thus reducing the volume of the entire device. When rolling up, this utility model can also be inverted, and the fireproof cloth 71 can be rolled up on the outside of the shaft 5 by the elastic force of the torsion spring.

[0020] Furthermore, such as Figure 4 As shown, a partition 77 is installed inside the shaft 5, and the internal area of ​​the shaft 5 is divided into several cavities by the partition 77. Each cavity corresponds independently to a fireproof curtain 7, that is, the flame retardant in each fireproof curtain 7 is stored in a separate cavity, thereby ensuring that the filling amount of flame retardant in each fireproof curtain 7 is consistent and the fireproof effect of each fireproof curtain 7 is consistent.

[0021] like Figure 1-4 As shown, a magnet 75 is embedded between the two layers of fireproof cloth 71. The magnets 75 are symmetrically distributed on both sides of the fireproof curtain 7, and adjacent fireproof curtains 7 are positioned by adsorption of the magnets 75. When no one is passing through, the multiple fireproof cloths 71 are adsorbed into a whole by the magnets 75. That is, there is no vertical misalignment between the multiple fireproof cloths 71, but it does not affect the passage of construction personnel while increasing its fireproof effect.

[0022] See Figure 2 As shown, a positioning rope 76 is provided inside the cavity 72. The positioning rope 76 is adhered to the inner wall of the fireproof cloth 71, and the positioning rope 76 is a component made of fire-resistant metal. On the one hand, the positioning rope 76 made of fire-resistant metal increases the overall fire resistance of the fireproof cloth 71. On the other hand, the positioning rope 76 limits the inner side of the cavity 72. It can be understood that the positioning rope 76 makes the expansion space of the cavity 72 consistent, that is, further ensures that the amount of flame retardant filling in each cavity 72 of each fireproof cloth 71 is consistent from bottom to top.

[0023] More specifically, a rope 81 is connected inside the positioning tube 8, and counterweights 82 are installed at both ends of the rope 81. The rope 81 and the counterweights 82 are detachable. In actual use, the counterweights 82 increase the overall weight of the fireproof cloth 71, so that the positioning tube 8 can be pressed on the indoor ground, reducing the gap between the bottom of the fireproof cloth 71 and the indoor ground.

[0024] 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 descriptions of the above embodiments and specifications are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of protection claimed by this utility model.
