Description

Technical Field

[0001] This utility model relates to the field of fire-fighting equipment, and in particular to a pressure sensor packaging structure for a fire extinguisher. Background Technology

[0002] Fire extinguishers are common fire prevention facilities that can extinguish initial fires, thereby reducing the losses caused by fires. Fire extinguishers typically consist of an extinguishing agent and compressed gas, and can be operated manually or automatically. Depending on the type of extinguishing agent and purpose, fire extinguishers can be classified as dry powder fire extinguishers, foam fire extinguishers, carbon dioxide fire extinguishers, etc.

[0003] Most existing fire extinguishers are equipped with pressure gauges on their tops to help users determine if the extinguisher is functioning properly. However, when the connection between the pressure gauge and the tank is unstable, the extinguisher may malfunction. Furthermore, existing fire extinguishers are usually stored in fire extinguisher boxes, where only simple locking mechanisms are in place. If the extinguisher falls off, it is not visible from the outside, thus reducing its lifespan. To address this technical problem, this application proposes a pressure sensor encapsulation structure for fire extinguishers. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a pressure sensor encapsulation structure for fire extinguishers. By limiting and fixing the bottom of the fire extinguisher, it can prevent the fire extinguisher from moving or tipping over, thus ensuring its stability. Furthermore, the fixing sleeve can prevent damage to the fire extinguisher caused by impacts or falls, extending its service life. By sealing the connection between the pressure gauge and the fixing base, it helps prevent leakage between the fire extinguisher and the pressure gauge, ensuring accurate pressure gauge readings, thereby guaranteeing the normal use and safety of the fire extinguisher.

[0005] To achieve the above objectives, the present invention provides the following technical solution:

[0006] A pressure sensor packaging structure for a fire extinguisher includes a fire extinguisher canister, a base at the bottom of the canister, a movable groove at the rear end of the base, a limit rod within the movable groove, a fixed seat at the top of the canister, and multiple limit tubes (II) on the outer wall of the fixed seat. One of the limit tubes (II) has a limit tube (I) connected to its front end via a threaded connection. A sealing assembly is located at the rear end of the limit tube (I). A bottom cover is fixedly connected to the front end of the limit tube (I). A pressure gauge is fixedly connected to the front end of the bottom cover. A sealing ring is located on the outer wall of the front end of the limit tube (I).

[0007] Furthermore, the sealing assembly includes a stop block fixedly connected to the rear end of the limiting tube, and a second sealing ring is provided at the rear end of the stop block, the second sealing ring being fixedly connected to the inner wall of the rear end of the limiting tube.

[0008] Furthermore, the outer wall of the first limiting tube and the inner wall of the middle end of the second limiting tube are both provided with matching threads.

[0009] Furthermore, movable blocks are fixedly connected to both ends of the limiting rod.

[0010] Furthermore, a fixing sleeve is fixedly connected to the top of the base.

[0011] Furthermore, a limiting groove is provided at the bottom end of the fire extinguisher tank.

[0012] Furthermore, a handle is provided at the top of the fixing base.

[0013] This utility model has the following beneficial effects:

[0014] 1. In this utility model, by limiting and fixing the bottom of the fire extinguisher, the fire extinguisher can be prevented from moving or tipping over, thereby ensuring its stability. Furthermore, by setting a fixing sleeve, the fire extinguisher can be prevented from being damaged by impact or falling, thus extending its service life.

[0015] 2. In this utility model, by sealing the connection between the pressure gauge and the fixed base, leakage at the connection between the fire extinguisher and the pressure gauge is prevented, ensuring the accuracy of the pressure gauge reading, thereby guaranteeing the normal use and safety of the fire extinguisher.

[0023] 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.

[0024] Reference Figure 1-3 This utility model provides an embodiment of a pressure sensor packaging structure for a fire extinguisher, including a fire extinguisher canister 1. A base 3 is provided at the bottom of the fire extinguisher canister 1. A movable groove 16 is provided at the rear end of the base 3. A limiting rod 15 is provided within the movable groove 16, and the limiting rod 15 can move within the movable groove 16 and the limiting groove 14. A fixed seat 13 is fixedly connected to the top of the fire extinguisher canister 1. Multiple limiting tubes 10 are provided on the outer wall of the fixed seat 13. The front end of one limiting tube 10 is threadedly connected to a limiting tube 8, and the other limiting tube 10 is a spray nozzle. The fire extinguisher tube and the rear end of the limiting tube 8 are fixedly connected to the abutment 9. The rear end of the abutment 9 is provided with a sealing ring 11. After installation, the rear end of the abutment 9 abuts against the sealing ring 11. The sealing ring 11 is fixedly connected to the inner wall of the rear end of the limiting tube 10. The front end of the limiting tube 8 is fixedly connected to the bottom cover 6. The front end of the bottom cover 6 is fixedly connected to the pressure gauge 5. The pressure gauge 5 can display the pressure value inside the fire extinguisher tank 1. The outer wall of the front end of the limiting tube 8 is provided with a sealing ring 7. After installation, the sealing ring 7 abuts against the inner wall of the front end of the limiting tube 10.

[0025] Reference Figure 3-5 The outer wall of the first limiting tube 8 and the inner wall of the middle end of the second limiting tube 10 are both provided with matching threads, which allow the pressure gauge 5 to be installed on the fixed base 13. Movable blocks 4 are fixedly connected to both ends of the limiting rod 15, allowing the operator to easily move the limiting rod 15. A fixed sleeve 2 is fixedly connected to the top of the base 3, preventing damage to the fire extinguisher from impacts or drops and extending its service life. A limiting groove 14 is provided at the bottom of the fire extinguisher tank 1. By moving the limiting rod 15 into the limiting groove 14, the bottom of the fire extinguisher tank 1 can be limited, preventing the fire extinguisher tank 1 from being removed. A handle 12 is provided at the top of the fixed base 13.

[0026] Working principle: When the fire extinguisher needs to be used, first grasp the moving block 4 and move it backward, so that the limiting rod 15 moves from the middle of the base 3 to the rear end, that is, the limiting rod 15 is moved out of the limiting groove 14, so that the operator can take out the fire extinguisher canister 1 for use. When installing the pressure gauge 5, insert the abutment 9 into the limiting tube 10 and rotate the pressure gauge 5 so that the thread on the outer wall of the limiting tube 8 and the thread on the inner wall of the limiting tube 10 are connected. After tightening, the abutment 9 abuts against the sealing ring 11, and the sealing ring 7 abuts against the inner wall of the front end of the limiting tube 10, thereby achieving a sealing effect.
