Description

Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, specifically to a fire extinguisher and its pressure alarm device. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool mainly used to extinguish fires. It is one of the most common fire-fighting equipment and is usually stored in public places or places where fires may occur. When using a fire extinguisher, it is necessary to use a pressure alarm device to ensure its effectiveness, improve fire-fighting efficiency, facilitate management and maintenance, and meet safety standards and regulatory requirements.

[0003] When using existing pressure alarm devices, in order to secure the pressure alarm device, a special mounting base or bracket is usually installed on the fire extinguisher. It is fixed to the fire extinguisher by screws, clips, etc., and then the pressure alarm device is installed on this mounting base or bracket. Because the installation process is relatively complicated, it requires precise measurement and positioning to ensure its stability and accuracy. Once the mounting base or bracket fails or needs maintenance, it may be necessary to disassemble the entire device, which increases the complexity and difficulty of maintenance.

[0004] To overcome the shortcomings of quick installation or removal of undervoltage alarm devices, the prior art (Chinese patent application number: 202222041255.5, application date: August 4, 2022) discloses a fire extinguisher undervoltage alarm device. This undervoltage alarm device forms a detachable connection through a plug-in connector, which facilitates the replacement of button batteries, is easy to operate and maintain, has low cost, simple and compact structure, is lightweight and practical, and uses button batteries to provide DC power, making it safe to operate and has good performance.

[0005] While existing technologies can solve the problem of installing or removing undervoltage alarm devices, the undervoltage alarm device can only be repaired by replacing the button battery, resulting in poor maintenance. Furthermore, although the undervoltage alarm device is connected by a plug-in connector, the sealing effect between the undervoltage alarm device and the fire extinguisher is poor, and the undervoltage alarm device is relatively easy to disassemble, making the fixation effect unstable.

[0006] Therefore, we proposed that fire extinguishers and their pressure alarm devices can effectively solve the above problems. Utility Model Content

[0007] The purpose of this utility model is to provide a fire extinguisher and its pressure alarm device to solve the problems mentioned in the background art. Currently, when using a fire extinguisher and its pressure alarm device, it is impossible to repair the low-voltage alarm device by replacing the button battery, resulting in poor maintenance.

[0031] 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.

[0032] Please see Figures 1-7 The present invention provides the following technical solution:

[0033] Example 1: To address the issue that a certain type of fire extinguisher and its pressure alarm device on the market cannot be repaired by replacing the button battery, resulting in poor maintenance, and that while the low-voltage alarm device is detachable via a plug-in connector, this does not ensure a good seal between the low-voltage alarm device and the fire extinguisher, and the device is easily disassembled, leading to unstable installation, the following solution can be referenced: Figure 1 -Appendix Figure 3 and attached Figure 5 -Appendix Figure 7The device includes a fire extinguisher body 1 and a pressure alarm device housing 4. A mounting pipe 2 is fixedly installed on the front top of the fire extinguisher body 1, and a sealing groove 3 is formed inside the mounting pipe 2. It also includes a connector 5 fixedly installed on the rear of the pressure alarm device housing 4, with the end of the connector 5 penetrating the mounting pipe 2. Several locking teeth 6 are fixedly connected to the outer wall behind the connector 5, with the ends of the locking teeth 6 fitting against the inner wall of the mounting pipe 2. An installation sleeve 7 is fitted onto the outer wall of the connector 5, and a sealing gasket 8 is fixedly installed on the rear of the installation sleeve 7, with the end of the sealing gasket 8 inserted into the sealing groove 3. Support frames 9 are fixedly installed on both sides of the installation sleeve 7, with threaded grooves inside the support frames 9, and screws 10 penetrating through the threaded grooves. A baffle 11 is fixedly installed on the left side of the screw 10, and bolts 12 penetrate the front and rear sides of the baffle 11, with the ends of the bolts 12 inserted into the support frames 9. A clamping plate 13 is fixedly connected to the right side of the screw 10. The connector 5 and locking teeth 6 are detachably connected to the mounting pipe 2, and the locking teeth 6 are made of rubber. The sealing gasket 8 and the sealing groove 3 are matched, and the sealing gasket 8 is set as a circular ring structure. The screw 10 is movably connected to the support frame 9 through the threaded groove, and the support frame 9 and the threaded groove are integrated. The clamping plate 13 and the mounting pipe 2 are detachably connected, and the clamping plate 13 is set as a semi-circular arc structure.

[0034] Workers insert the connector 5, connected to the outer shell 4 of the pressure alarm device, into the mounting pipe 2, connected to the body 1 of the fire extinguisher. This causes several locking teeth 6 connected to the connector 5 to be pressed against the inner wall of the mounting pipe 2. The locking teeth 6 are made of rubber, providing elasticity and anti-slip properties, thus facilitating the quick installation or disassembly of the pressure alarm device onto the fire extinguisher for maintenance. During the installation of the connector 5, the sealing gasket 8 connected to the mounting sleeve 7 is inserted into the sealing groove 3, increasing the sealing effect between the pressure alarm device and the fire extinguisher. Then, each screw 10 is manually rotated, causing it to rotate within the support frame 9 through the corresponding threaded groove. This causes the screw 10 to move the clamping plates 13, making them fit against the outer wall of the mounting pipe 2. Finally, each bolt 12 is manually inserted through the baffle 11 into the support frame 9, thus fixing the clamping plates 13 connected to the screw 10 and clamping the mounting pipe 2, increasing the stability of the pressure alarm device and the fire extinguisher installation.

[0035] Example 2: Real-time monitoring of fire extinguisher and alarm functions, precise alarm and location tracking, and flexible settings are available.
