Description

Technical Field

[0001] This utility model belongs to the field of fire extinguisher technology, specifically relating to a high-temperature fire extinguisher. Background Technology

[0002] High-temperature fire extinguishers typically refer to fire extinguishers that can operate stably in high-temperature environments (such as industrial furnaces or near high-temperature equipment) or extinguish fires caused by high temperatures (such as fires involving molten materials). The core features are high-temperature resistance and the ability to extinguish fires in high-temperature environments.

[0003] Patent publication number CN 216358772 U discloses a high-temperature resistant fire extinguisher cylinder, including a cylinder body. The outer surface of the cylinder body is coated with a heat insulation layer. A first fixing sleeve and a second fixing sleeve are fixedly fitted onto the outer surface of the cylinder body. A handle is provided on the top surface of the cylinder body. An installation groove is provided on the bottom surface of the first fixing sleeve. This patent allows the label to be covered by pushing the sealing cap and then pushing the sealing cap further into the installation groove, using a locking cap and a threaded sleeve.

[0004] However, current fire extinguishers have the following problems: the position of the connecting pipe and nozzle used for spraying cannot be fixed tightly to the tank body by the fixing rod to prevent loosening and pre-fixing storage, which causes friction between the parts due to shaking, increasing wear and aging, and delaying the time to extinguish the fire due to loosening, tangling and knotting before emergency use. Therefore, we have proposed a high-temperature fire extinguisher. Utility Model Content

[0005] The purpose of this utility model is to provide a high-temperature fire extinguisher that can solve the problem in related technologies where the position of the connecting pipe and nozzle used for spraying cannot be tightly attached to the tank body by fixing rods to prevent loosening and pre-fixing storage, which leads to friction between components due to shaking, increasing wear and aging, and delaying the fire extinguishing time due to loosening, tangling and knotting before emergency use.

[0006] The specific technical solution adopted by this utility model is as follows:

[0007] A high-temperature fire extinguisher includes a fire extinguisher, a connecting pipe extending through its side, a nozzle extending through one end of the connecting pipe, a limiting and fixing assembly provided on the outer wall of the fire extinguisher, the limiting and fixing assembly including a support frame, the side of the support frame being fixedly connected to the outer wall of the fire extinguisher, a displacement rod slidably connected to the inner wall of the support frame, a rotating shaft being rotatably connected to one end of the displacement rod, a fixing rod being fixedly connected to the circumference of the rotating shaft, a limiting rod being rotatably connected to the side of the displacement rod, and a slot being provided on the side of the support frame.

[0008] The slots are located on the displacement trajectory of the limiting rod. Several slots are provided and arranged linearly on the side of the support frame. The top of the displacement rod has a rectangular groove and several slots, which facilitates fixing the fixing rod in multiple positions and provides multiple options.

[0009] A locking rod is rotatably connected to the top of the rotating shaft. The rectangular groove is located on the displacement trajectory of the locking rod. The fixing rod is located on the side of the connecting tube, and the connecting tube is located on the displacement trajectory of the fixing rod. The design of the locking rod is beneficial to fixing the position of the rotating shaft, so that the rotating shaft is temporarily fixed in place.

[0010] A spring is fixedly connected to the side of the displacement rod. The end of the spring away from the displacement rod is fixedly connected to the inner wall of the support frame. The design of the spring allows it to automatically reset when the displacement rod is not moved.

[0011] The fire extinguisher is equipped with a scraping and cleaning assembly on its outer wall. The scraping and cleaning assembly includes a lever, one end of which is fixedly connected to the bottom of a displacement rod. A horizontal frame is fixedly connected to the outer wall of the fire extinguisher, and a sliding rod is slidably connected to the inner wall of the horizontal frame. A scraper is fixedly connected to the side of the sliding rod. By moving the scraper, the bottom of the fire extinguisher nozzle is scraped and cleaned.

[0012] A second spring is fixedly connected to the side of the slide rod. The end of the second spring away from the slide rod is fixedly connected to the inner wall of the horizontal frame. The nozzle is located on the displacement trajectory of the scraper. The design of the second spring is conducive to the slide rod automatically returning to its original position when it is not squeezed or moved.

[0013] The fire extinguisher is equipped with a pressure gauge on its side and a placement groove on its outer wall. The placement groove is located on the displacement trajectory of the connecting pipe. The design of the placement groove helps to hold one end of the connecting pipe in place and initially restricts the position of the connecting pipe.

[0014] The technical effects achieved by this utility model are as follows:

[0015] This utility model utilizes the interoperable design of internal fixing rods, locking rods, and limiting rods within the limiting and fixing assembly. The fixing rods ensure the extinguisher is tightly attached to the tank body, preventing loosening and friction between components due to shaking or contact with other high-temperature structures. This reduces wear and aging, extending the service life of key components in high-temperature fire extinguishers. In high-temperature scenarios requiring rapid response, the pre-fixed and stored connecting pipes and nozzles prevent them from becoming loose, tangled, or knotted before emergency use, ensuring direct connection and use without delaying firefighting.

[0016] This invention utilizes the coordinated design of components such as the toggle lever, scraper, and slide bar within the scraping cleaning assembly to automatically clean residual impurities from the nozzle. This prevents clogging under high temperatures, ensuring unobstructed nozzle flow and normal spraying during firefighting. The double-spring reset design guarantees multiple cleaning cycles, maintaining the nozzle's reliable performance under high-temperature conditions and improving emergency firefighting efficiency.

[0024] To make the objectives and advantages of this utility model clearer, the following detailed description is provided in conjunction with embodiments. It should be understood that the following text is merely used to describe one or more specific embodiments of this utility model and does not strictly limit the scope of protection specifically claimed by this utility model.

[0025] like Figure 1-5As shown, a high-temperature fire extinguisher includes a fire extinguisher 1, a connecting pipe 2 passing through the side of the fire extinguisher 1, a nozzle 310 passing through one end of the connecting pipe 2, a limiting and fixing component 3 provided on the outer wall of the fire extinguisher 1, the limiting and fixing component 3 including a support frame 31, the side of the support frame 31 being fixedly connected to the outer wall of the fire extinguisher 1, a displacement rod 32 being slidably connected to the inner wall of the support frame 31, a rotating shaft 33 being rotatably connected to one end of the displacement rod 32, a fixing rod 34 being fixedly connected to the circumferential surface of the rotating shaft 33, a limiting rod 35 being rotatably connected to the side of the displacement rod 32, and a slot 36 being provided on the side of the support frame 31.

[0026] The slot 36 is located on the displacement trajectory of the limiting rod 35. Several slots 36 are provided and are arranged linearly on the side of the support frame 31. A rectangular slot 39 is provided on the top of the displacement rod 32, and several slots 36 are provided, which is beneficial to fix the fixing rod 34 in multiple positions and provide multiple options.

[0027] A locking rod 38 is rotatably connected to the top of the rotating shaft 33. A rectangular groove 39 is located on the displacement trajectory of the locking rod 38. A fixing rod 34 is located on the side of the connecting pipe 2. The connecting pipe 2 is located on the displacement trajectory of the fixing rod 34. The design of the locking rod 38 is conducive to fixing the position of the rotating shaft 33, so that the rotating shaft 33 is temporarily fixed in place.

[0028] A spring 37 is fixedly connected to the side of the displacement rod 32. The end of the spring 37 away from the displacement rod 32 is fixedly connected to the inner wall of the support frame 31. The design of the spring 37 is conducive to automatic reset when the displacement rod 32 is not moved.

[0029] According to the above structure, when the fire extinguisher 1 is not in use and is being stored, the connecting pipe 2 and nozzle 310 are in a loose state. First, the connecting pipe 2 is snapped into the placement slot 6 for initial fixation. Pulling the displacement rod 32 along the inner wall of the support frame 31 towards the side closer to the fire extinguisher 1 will cause the rotating shaft 33, fixing rod 34, rectangular slot 39, and locking rod 38 to move towards the side closer to the fire extinguisher 1. The fixing rod 34 is located on the side of the connecting pipe 2. When the fixing rod 34 moves towards the side closer to the fire extinguisher 1, it will press down on the connecting pipe 2, using the fixing rod 34 to press the connecting pipe 2 against the outer wall of the fire extinguisher 1 tank, reducing the looseness of the connecting pipe 2 and nozzle 310. After the fixing rod 34 presses down on the connecting pipe 2, it will cause the limiting rod 35 to rotate towards the side closer to the slot 36, penetrating into the slot 36, thus fixing the position of the displacement rod 32 and the fixing rod 34, allowing for continuous operation. The position of the limiting connecting pipe 2 and the fixing rod 34 can be adjusted. When the fixing rod 34 is not needed to press down the connecting pipe 2, the fixing rod 34 is driven to rotate along the rotating shaft 33 to the side away from the connecting pipe 2, so that the fixing rod 34 is no longer horizontally located on the side of the connecting pipe 2, which does not affect the use of the connecting pipe 2. When the position is adjusted, the locking rod 38 is driven to pass through the rectangular groove 39 along one end of the rotating shaft 33 to lock the position of the rotating shaft 33 and the fixing rod 34. The fixing rod 34 is used to keep them tightly against the tank body and prevent loosening. This can prevent friction between parts due to shaking or contact with other high-temperature structures, reduce wear and aging, and extend the service life of key components of the high-temperature fire extinguisher 1. Fire extinguishing in high-temperature scenarios requires a rapid response. The connecting pipe 2 and the nozzle 310 are pre-fixed and stored to prevent them from being loose, tangled or knotted before emergency use, ensuring that they can be directly connected and used after being taken out, without delaying the fire extinguishing opportunity.

[0030] like Figure 1-5 As shown, a scraping and cleaning assembly 4 is provided on the outer wall of the fire extinguisher 1. The scraping and cleaning assembly 4 includes a toggle lever 41, one end of which is fixedly connected to the bottom of the displacement lever 32. A horizontal frame 42 is fixedly connected to the outer wall of the fire extinguisher 1. A sliding rod 43 is slidably connected to the inner wall of the horizontal frame 42. A scraper 44 is fixedly connected to the side of the sliding rod 43. By moving the scraper 44, the bottom of the nozzle 310 of the fire extinguisher 1 is scraped and cleaned.

[0031] A second spring 45 is fixedly connected to the side of the slide bar 43. The end of the second spring 45 away from the slide bar 43 is fixedly connected to the inner wall of the cross frame 42. The nozzle 310 is located on the displacement trajectory of the scraper 44. The design of the second spring 45 is conducive to the automatic reset of the slide bar 43 when it is not squeezed or moved.

[0032] A pressure gauge 5 is installed on the side of the fire extinguisher 1, and a placement groove 6 is installed on the outer wall of the fire extinguisher 1. The placement groove 6 is located on the displacement trajectory of the connecting pipe 2. The design of the placement groove 6 is conducive to locking one end of the connecting pipe 2 and initially restricting the position of the connecting pipe 2.

[0033] According to the above structure, the displacement rod 32 moves towards the side closer to the fire extinguisher 1. The movement of the displacement rod 32 will drive the actuating rod 41 to move, causing the actuating rod 41 to slide towards the side closer to the sliding rod 43. The sliding rod 43 is located on the movement trajectory of the actuating rod 41. When the actuating rod 41 moves, it will squeeze the sliding rod 43, causing the sliding rod 43 to move along the horizontal frame 42 towards the side closer to the fire extinguisher 1. The movement of the sliding rod 43 will drive the scraper rod 44 to move. The scraper rod 44 is located at the bottom of the nozzle 310. When the scraper rod 44 moves, it will scrape the bottom of the nozzle 310 to clean the nozzle 310. When the sliding rod 43 is not squeezed, the scraper rod 44 will automatically reset through the second spring 45, which facilitates the subsequent scraping of the nozzle 310. It can automatically clean the residual impurities in the nozzle 310, avoid impurities clogging in high temperature environments, and ensure that the nozzle 310 is unobstructed and sprays normally during fire extinguishing. The reset design of the second spring 45 ensures multiple cleanings, maintains the reliability of the nozzle 310 under high temperature conditions, and improves the emergency fire extinguishing efficiency.

[0034] The above description is merely a preferred embodiment of this utility model. It should be noted that those skilled in the art can make various improvements and modifications without departing from the principle of this utility model, and these improvements and modifications should also be considered within the scope of protection of this utility model. Structures, devices, and operating methods not specifically described or explained in this utility model, unless otherwise specified or limited, shall be implemented using conventional methods in the field.
