Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher protection technology, and in particular to a shockproof protection structure for a fire extinguisher pressure gauge. Background Technology

[0002] A fire extinguisher is a portable fire-fighting device, typically consisting of a pressure vessel, extinguishing agent, drive mechanism, and operating components. It is used to extinguish initial fires. Through pressure, it rapidly sprays an extinguishing agent (such as dry powder, foam, or carbon dioxide) to isolate oxygen, cool burning materials, or inhibit chain reactions, thereby extinguishing the fire. Fire extinguishers are classified into categories A, B, C (solid, liquid, and gas fires), and D (metal fires), etc. Their pressure and expiration date must be checked regularly to ensure reliable use in emergencies. Widely deployed in buildings, vehicles, and industrial sites, they are a crucial emergency tool for fire safety.

[0003] A search revealed a fire extinguisher (authorization announcement number: CN 221384984 U) that "comprises a fire extinguisher cylinder, with a handle on the right side inside the cylinder, a cylinder opening on the top of the cylinder, a pressure gauge, a pressure valve, and a pressure valve control switch on the cylinder opening, a pipe outlet on the left side of the cylinder opening, heat-insulating foam on the outside of the cylinder, and a fixed base at the bottom of the cylinder. This type of fire extinguisher, with its handle, effectively solves the difficulty of retrieving the fire extinguisher from confined spaces in a hurry, and also allows firefighters to better grasp the fire extinguisher, greatly increasing firefighting efficiency; the fixed base protects the fire extinguisher from external shaking and collisions during storage; and the heat-insulating foam solves the problem of the cylinder being difficult to heat, which is common with perfluorohexanone fire extinguishers."

[0004] Based on the aforementioned technologies, the applicant believes that existing fire extinguishers mostly use pressure gauges to monitor the pressure inside the cylinder. However, pressure gauges, as separately installed instruments, are very fragile. Existing pressure gauges lack protective devices and shock-absorbing mechanisms for the fire extinguisher itself. Strong and prolonged vibrations during transportation may damage the fire extinguisher. In response to the above problems, we have introduced a shockproof protection structure for fire extinguisher pressure gauges. Utility Model Content

[0005] This utility model discloses a shockproof protection structure for a fire extinguisher pressure gauge, which aims to solve the technical problem that existing pressure gauges lack protective devices and fire extinguishers lack vibration damping mechanisms, and that strong and long-term vibrations during transportation may damage the fire extinguisher.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A shockproof protection structure for a fire extinguisher pressure gauge includes a fire extinguisher body. A switch valve is fixedly connected to the top of the fire extinguisher body, and a pressure gauge is fixedly connected to the outside of the switch valve. A protective base is provided at the bottom of the fire extinguisher body. A buffer assembly and a protective assembly are provided on the outside of the fire extinguisher body. The buffer assembly and the protective assembly cooperate with each other. The buffer assembly includes a buffer groove, which is circumferentially arrayed inside the protective base. A sliding column is fixedly connected inside the buffer groove. A lifting block is slidably connected to the outside of the sliding column. The lifting block is fixedly connected to the fire extinguisher body. A pressing spring is sleeved on the outside of the sliding column and above the lifting block. A buffer airbag is fixedly connected to the bottom of the inner wall of the protective base. The buffer airbag and the pressing spring cooperate with each other.

[0008] The built-in buffer components can buffer and filter the vibration force received by the fire extinguisher, improve its shock resistance, and prevent damage to the fire extinguisher due to large-scale and long-term vibration. The structure is simple and highly practical.

[0009] In a preferred embodiment, the protective assembly includes a mounting frame symmetrically and fixedly connected to the outside of the fire extinguisher body. A protective cover is provided above the fire extinguisher body, and the bottom of the protective cover is inserted into the interior of the mounting frame. The inner walls of both mounting frames are fixedly connected with rubber layers for increasing friction.

[0010] The protective assembly, through the cooperation of the mounting frame and the protective cover, provides physical protection for the pressure gauge, preventing external impacts or dust intrusion. The rubber layer on the inner wall of the mounting frame increases friction, ensuring a secure installation of the protective cover and preventing accidental detachment. The weight-reducing groove design of the protective cover reduces the overall weight while maintaining strength, facilitating operation.

[0011] In a preferred embodiment, a silicone pad with a thickness of 11 mm is fixedly connected to the bottom of the protective base.

[0012] The 11mm thick silicone pad enhances the shock absorption of the protective base, effectively absorbing ground impacts and preventing damage to the fire extinguisher body during storage or transportation, while also improving placement stability.

[0013] In a preferred embodiment, a nozzle is fixedly connected to the outside of the switch valve, and a limit buckle is installed on the outside of the fire extinguisher body. The limit buckle and the nozzle work together.

[0014] The use of the limit buckle in conjunction with the nozzle ensures that the nozzle is securely fixed when not in use, preventing shaking or loosening and improving the overall structural reliability of the fire extinguisher.

[0015] In a preferred embodiment, the interior of the protective cover is provided with weight-reducing grooves at equal intervals for weight reduction.

[0016] The weight-reducing grooves inside the protective cover optimize the structural weight, ensuring that it provides sufficient protection without compromising portability, allowing users to quickly access the fire extinguisher.

[0017] In a preferred embodiment, the outer wall of the fire extinguisher body is coated with an anti-rust coating, the main material of which is epoxy zinc-rich primer.

[0018] The epoxy zinc-rich primer coating on the outer wall of the fire extinguisher body enhances corrosion resistance and extends the service life of the fire extinguisher, making it especially suitable for humid or chemically corrosive environments.

[0019] The shockproof protection structure for a fire extinguisher pressure gauge provided by this utility model has the following advantages:

[0020] Firstly, the buffer components can buffer and filter the vibration force received by the fire extinguisher, improve its shock resistance, and prevent damage to the fire extinguisher due to large-scale and long-term vibration. The structure is simple and highly practical.

[0021] Secondly, the 11mm thick silicone pad enhances the shock absorption of the protective base, effectively absorbing ground impacts and preventing damage to the fire extinguisher body during storage or transportation, while also improving placement stability. The use of the limiting buckle in conjunction with the nozzle ensures the nozzle is securely fixed when not in use, preventing shaking or loosening and improving the overall structural reliability of the fire extinguisher. The weight-reducing groove inside the protective cover optimizes the structural weight, providing sufficient protection without compromising portability, allowing users to quickly retrieve the fire extinguisher. The epoxy zinc-rich primer anti-rust coating on the outer wall of the fire extinguisher body enhances corrosion resistance and extends the fire extinguisher's service life, making it particularly suitable for humid or chemically corrosive environments.

[0028] The technical solutions of the embodiments of this application will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of this application, and not all embodiments. The components of the embodiments of this application described and marked in the accompanying drawings can be arranged and designed in various different configurations. Therefore, the following detailed description of the embodiments of this application provided in the accompanying drawings is not intended to limit the scope of the claimed application, but merely represents selected embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application without inventive effort are within the scope of protection of this application.

[0029] The shockproof protection structure for a fire extinguisher pressure gauge disclosed in this utility model is mainly used in fire extinguisher protection scenarios.

[0030] Reference Figure 1 - Figure 5 A shockproof protection structure for a fire extinguisher pressure gauge includes a fire extinguisher body 1, a switch valve 2 fixedly connected to the top of the fire extinguisher body 1, a pressure gauge 3 fixedly connected to the outside of the switch valve 2, a protective base 4 at the bottom of the fire extinguisher body 1, a buffer assembly and a protective assembly on the outside of the fire extinguisher body 1, the buffer assembly and the protective assembly working together, the buffer assembly including a buffer groove 51, a set of buffer grooves 51 arranged in a circumferential array inside the protective base 4, a sliding column 52 fixedly connected inside the buffer groove 51, a lifting block 53 slidably connected to the outside of the sliding column 52, the lifting block 53 being fixedly connected to the fire extinguisher body 1, a pressing spring 54 sleeved on the outside of the sliding column 52 and above the lifting block 53, and a buffer airbag 55 fixedly connected to the bottom of the inner wall of the protective base 4, the buffer airbag 55 working together with the pressing spring 54. The protective assembly includes a mounting frame 6, which is symmetrically fixed to the outside of the fire extinguisher body 1. A protective cover 7 is provided on the top of the fire extinguisher body 1, and the bottom of the protective cover 7 is inserted into the inside of the mounting frame 6. The inner walls of both mounting frames 6 are fixedly connected with rubber layers to increase friction.

[0031] In this embodiment, the shockproof protection structure for the fire extinguisher pressure gauge works in concert with the buffer component and the protective component. When the fire extinguisher is subjected to vibration or impact, the lifting block 53 in the buffer groove 51 slides along the sliding column 52 and compresses the pressing spring 54. At the same time, the buffer airbag 55 absorbs the remaining impact force, forming multi-stage shock absorption. Through the support of the buffer airbag 55 and the pressing of the pressing spring 54, the fire extinguisher quickly recovers stability after being subjected to vibration. The protective cover 7 is inserted into the inside of the mounting frame 6. The protective cover 7 and the mounting frame 6 protect the pressure gauge 3 from external impacts and bumps. Through the buffer component, the vibration force received by the fire extinguisher can be buffered and filtered, improving the shock resistance performance and avoiding damage to the fire extinguisher due to large-amplitude and long-term vibration. The structure is simple and highly practical.

[0032] In the above technical solution, considering that existing pressure gauges lack protective devices and fire extinguishers lack vibration damping mechanisms, strong and prolonged vibrations during transportation may damage the fire extinguishers. To solve this problem, the specific operation is as follows:

[0033] Reference Figure 1 - Figure 5 In a preferred embodiment, a silicone pad 8 with a thickness of 11 mm is fixedly connected to the bottom of the protective base 4. A nozzle 10 is fixedly connected to the outside of the switch valve 2, and a limit buckle 9 is installed on the outside of the fire extinguisher body 1. The limit buckle 9 and the nozzle 10 cooperate with each other. Weight-reducing grooves for weight reduction are equidistantly opened inside the protective cover 7. The outer wall of the fire extinguisher body 1 is coated with an anti-rust coating, the main material of which is epoxy zinc-rich primer.

[0034] In this embodiment: The 11mm thickness of the silicone pad 8 enhances the shock absorption capacity of the protective base 4, effectively absorbing ground impacts and preventing damage to the fire extinguisher body 1 during storage or transportation, while also improving placement stability. The cooperation between the limiting buckle 9 and the nozzle 10 ensures that the nozzle 10 is securely fixed when not in use, preventing shaking or loosening and improving the overall structural reliability of the fire extinguisher. The weight-reducing groove inside the protective cover 7 optimizes the structural weight, providing sufficient protection without compromising portability, allowing users to quickly retrieve the fire extinguisher. The epoxy zinc-rich primer anti-rust coating on the outer wall of the fire extinguisher body 1 enhances corrosion resistance and extends the service life of the fire extinguisher, making it particularly suitable for humid or chemically corrosive environments.

[0035] Working principle: The shockproof protection structure of the pressure gauge of this fire extinguisher works in concert with the buffer component and the protective component. When the fire extinguisher is subjected to vibration or impact, the lifting block 53 in the buffer groove 51 slides along the sliding column 52 and compresses the pressing spring 54. At the same time, the buffer airbag 55 absorbs the remaining impact force, forming multi-stage shock absorption. Through the support of the buffer airbag 55 and the pressing of the pressing spring 54, the fire extinguisher is kept stable after being vibrated. The protective cover 7 and the mounting frame 6 protect the pressure gauge 3 from external impact. The silicone pad 8 further absorbs ground vibration, ensuring that the fire extinguisher remains stable during transportation or storage. The limit buckle 9 fixes the nozzle 10 to prevent it from loosening, while the anti-rust coating enhances the corrosion resistance of the fire extinguisher body 1 and improves the overall durability.

[0036] The above description is merely a preferred embodiment of this utility model, but the protection scope of this utility model is not limited thereto. The substitutions may be replacements of some structures, devices, or method steps, or they may be complete technical solutions. Equivalent substitutions or modifications made based on the technical solution and inventive concept of this utility model should all be covered within the protection scope of this utility model.
