Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, specifically an explosion-proof fire extinguisher. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool. It contains chemicals used to extinguish fires. Fire extinguishers are one of the most common fire prevention facilities and are stored in public places or places where fires may occur. Different types of fire extinguishers contain different components and are designed for different causes of fires. Care must be taken when using them to avoid adverse effects and dangers.

[0003] Some existing fire extinguishers need to be hung high on the wall. When a fire occurs, the indoor temperature rises. When the fire extinguisher is enveloped by flames or hot smoke, the internal temperature of the fire extinguisher increases, leading to increased pressure and potentially causing the fire extinguisher to explode. Therefore, the explosion-proof effect of fire extinguishers is poor. Utility Model Content

[0004] The purpose of this invention is to provide an explosion-proof fire extinguisher to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution: An explosion-proof fire extinguisher includes: The fire extinguisher cylinder has fixing rings symmetrically fixedly installed on its outer surface. A sealing assembly is disposed on the outside of the fire extinguisher cylinder. The sealing assembly includes a base, a first protective cover is fixedly installed on one side surface of the base, and a second protective cover is rotatably connected to the outside of the first protective cover. The vent pipe is fixedly embedded in the inner surface of the No. 1 protective cover.

[0006] Furthermore, a one-way valve is fixedly installed inside the air outlet pipe, and a temperature-sensing glass tube is provided on one side surface of the base.

[0007] Furthermore, a fixing bracket is symmetrically fixedly installed on the lower surface of the base and the upper surface of the first protective cover.

[0008] Furthermore, multiple U-shaped card frames are fixedly installed at equal angles on the outer surface of the fixed ring, and multiple card blocks are fixedly installed at equal angles at both ends of the inner surface of the first protective cover, with the multiple card blocks respectively movably inserted into the U-shaped card frames at corresponding positions.

[0009] Furthermore, a sealing ring that is movably fitted to the first protective cover is fixedly installed at the upper end of the outer surface of the fire extinguisher cylinder, and a conical sealing ring that is movably fitted to the second protective cover is fixedly installed on the lower surface of the sealing ring.

[0010] Furthermore, a limiting ring is fixedly installed on one side surface of the base, and the second protective cover is movably fitted with the inner surface of the limiting ring. Multiple L-shaped limiting plates are fixedly installed at equal angles on the upper end of the first protective cover.

[0011] Preferably, an incomplete gear ring is fixedly installed at the upper end of the outer surface of the first protective cover, the incomplete gear ring is movably fitted with the inner surface of the L-shaped limiting plate, a motor is fixedly installed at the upper end of the first protective cover, and a gear that meshes and drives with the incomplete gear ring is fixedly installed at the output end of the motor.

[0012] Compared with the prior art, the beneficial effects of this utility model are: 1. By placing the fire extinguisher cylinder on top of the base, multiple U-shaped clips are secured to the outside of the clip block to limit and fix the fire extinguisher cylinder. At the same time, after the fire extinguisher cylinder is lifted up slightly, the U-shaped clips separate from the clip block, making it easy to remove the fire extinguisher cylinder for use. The sealing ring fits into the No. 1 protective cover, and the conical sealing ring fits into the closed No. 2 protective cover to improve the sealing effect.

[0013] 2. The motor runs, driving the gear to rotate, which in turn causes the incomplete gear ring to rotate the No. 2 protective cover. Together with the No. 1 protective cover, the base, and the sealing ring, they form a closed space. This closed space covers the outside of the fire extinguisher, preventing the heat from the flames and high-temperature smoke from being transferred to the fire extinguisher, thus avoiding an explosion caused by increased internal pressure and improving the explosion-proof effect.

[0014] 3. When the fire lasts for a long time and the internal temperature of the sealed component rises, the high temperature causes the temperature-sensing glass tube to rupture, and the liquid inside flows out. The liquid absorbs heat and evaporates, which increases the internal pressure of the sealed component. The increased pressure causes the one-way valve to open, allowing water vapor to carry heat out from the vent pipe, thereby reducing the internal temperature of the sealed component and further improving the protective effect of the fire extinguisher.

[0017] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0018] Please see Figure 1-4 In this embodiment of the utility model, an explosion-proof fire extinguisher includes a fire extinguisher cylinder 1. A fixing ring 101 is symmetrically fixedly installed on the outer surface of the fire extinguisher cylinder 1. A sealing component 2 is disposed on the outer side of the fire extinguisher cylinder 1. The sealing component 2 includes a base 201. A first protective cover 202 is fixedly installed on one side surface of the base 201. A second protective cover 206 is rotatably connected to the outer side of the first protective cover 202. A fixing bracket 203 is symmetrically fixedly installed on the lower surface of the base 201 and the upper surface of the first protective cover 202. An air outlet pipe 3 is fixedly embedded in the inner surface of the first protective cover 202.

[0019] Specifically, two fixing brackets 203 are fixed to the wall with expansion bolts to fix the sealing component 2, so that the fire extinguisher cylinder 1 can be suspended high on the wall with the help of the sealing component 2. The second protective cover 206 is stored behind the first protective cover 202, so that the fire extinguisher cylinder 1 can be pulled up and moved out from the opening of the first protective cover 202.

[0020] Example 1 like Figure 2 and Figure 3 As shown, in this embodiment, multiple U-shaped clip frames 102 are fixedly installed at equal angles on the outer surface of the fixing ring 101, and multiple clip blocks 105 are fixedly installed at equal angles at both ends of the inner surface of the first protective cover 202. The multiple clip blocks 105 are movably inserted into the U-shaped clip frames 102 at corresponding positions. A closing ring 103 that movably fits the first protective cover 202 is fixedly installed at the upper end of the outer surface of the fire extinguisher cylinder 1, and a conical sealing ring 104 that movably fits the second protective cover 206 is fixedly installed on the lower surface of the closing ring 103.

[0021] In this embodiment, when the fire extinguisher cylinder 1 is placed above the base 201, multiple U-shaped clips 102 are clipped onto the outside of the clip 105 to limit and fix the fire extinguisher cylinder 1. At the same time, through the movable insertion of the U-shaped clips 102 and the clip 105, the fire extinguisher cylinder 1 is lifted up slightly, making it easy to remove the fire extinguisher cylinder 1 for use. The sealing ring 103 fits into the first protective cover 202, and the conical sealing ring 104 fits into the second protective cover 206 in the closed state to improve the sealing effect.

[0022] like Figure 2-4 As shown, in this embodiment, a limiting ring 204 is fixedly installed on one side surface of the base 201, and the second protective cover 206 is movably fitted with the inner surface of the limiting ring 204. Multiple L-shaped limiting plates 205 are fixedly installed at equal angles on the upper end of the first protective cover 202. An incomplete gear ring 207 is fixedly installed at the upper end of the outer surface of the first protective cover 202. The incomplete gear ring 207 is movably fitted with the inner surface of the L-shaped limiting plate 205. A motor 208 is fixedly installed on the upper end of the first protective cover 202. A gear 209 that meshes and drives with the incomplete gear ring 207 is fixedly installed at the output end of the motor 208.

[0023] In practice, when a fire occurs, the motor 208 operates, driving the gear 209 to rotate. Through the meshing transmission of the gear 209 and the incomplete gear ring 207, and under the limitation of the L-shaped limiting plate 205 and the limiting ring 204, the incomplete gear ring 207 drives the second protective cover 206 to rotate. Together with the first protective cover 202, the base 201 and the sealing ring 103, a closed space is formed. This closed space covers the outside of the fire extinguisher, preventing the heat of the flame and high-temperature smoke from being transferred to the fire extinguisher, thus preventing an explosion caused by an increase in internal pressure and improving the explosion-proof effect.

[0024] Example 2 Based on Example 1, in order to compensate for the problem of increased internal temperature of the enclosed component 2 caused by the long duration of the fire.

[0025] like Figure 3 As shown, in this embodiment, a one-way valve is fixedly installed inside the air outlet pipe 3, and a temperature-sensing glass tube 301 is provided on one side surface of the base 201.

[0026] In practice, when the fire lasts for a long time and the internal temperature of the sealing component 2 rises, the high temperature causes the heat-sensing glass tube 301 to rupture, and the liquid inside it flows out. The liquid absorbs heat and evaporates, which increases the internal pressure of the sealing component 2. After the pressure increases, the one-way valve opens, allowing water vapor to carry heat out from the vent pipe 3, reducing the internal temperature of the sealing component 2 and further improving the protective effect of the fire extinguisher.

[0027] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0028] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
