Technical Field

[0001] This utility model relates to the field of fire extinguisher technology, and in particular to an easy-to-operate one-handed press handle for a fire extinguisher. Background Technology

[0002] Fire extinguishers are essential fire-fighting equipment used to extinguish initial fires and protect lives and property. They are widely used in homes, shopping malls, factories, and other places. In the emergency of a sudden fire, the ability to quickly and easily operate a fire extinguisher directly affects whether the fire can be controlled and extinguished in a timely manner.

[0003] In existing technologies, traditional fire extinguisher operation often requires the use of both hands. For example, one hand holds the extinguisher cylinder while the other hand operates the handle to extinguish the fire. This method can be inconvenient in some emergency situations, such as when the user only has one hand to operate the extinguisher or needs to perform other auxiliary actions (such as opening a passageway door or retrieving protective equipment). Operating the extinguisher with both hands becomes difficult. Furthermore, the nozzle of traditional fire extinguishers usually requires the user to hold it with their hand at all times to ensure its stability, which increases the complexity of operation and distracts the user. Therefore, improvements are needed. Utility Model Content

[0004] The purpose of this utility model is to solve the problems of inconvenience in operating fire extinguishers with both hands, imperfect function of operating fire extinguishers with one hand, and the fact that users usually need to hold the nozzle of traditional fire extinguishers with their hands when using them.

[0025] To better understand the above-mentioned objectives, features, and advantages of this utility model, the present utility model will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in these embodiments can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of the present invention. However, the present invention may also be implemented in other ways different from those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1: As Figures 1-5As shown, this utility model provides a technical solution: an easy-to-operate one-handed press handle for a fire extinguisher, including a fire extinguisher body 1, a press switch 2 on the upper surface of the fire extinguisher body 1, a safety pin 3 inside the press switch 2, a nozzle 4 on the upper surface of the fire extinguisher body 1, a nozzle head 5 fixedly installed at one end of the nozzle 4, a U-shaped frame 6 fixedly installed on the side of the fire extinguisher body 1, a handle 7 fixedly installed on the inner side of the U-shaped frame 6, a press frame 8 fixedly installed on the upper surface of the U-shaped frame 6, and a press block 9 slidably connected inside the press frame 8. A connecting rope 10 is fixedly connected to the fire extinguisher body 1. A hook 11 is fixedly installed at one end of the connecting rope 10. A hanging hole 12 is opened through the surface of the push switch 2. A sliding rod 13 is fixedly installed inside the push frame 8. A tension spring A14 is sleeved on the surface of the sliding rod 13. A fixing frame 15 is fixedly installed on the side of the fire extinguisher body 1. A rotating block 16 is rotatably connected to the inside of the fixing frame 15. A placement frame 17 is fixedly installed on the lower surface of the rotating block 16. A tension spring B18 is fixedly connected inside the rotating block 16. A locking block 19 is slidably connected inside the rotating block 16. A fixing plate 21 is fixedly mounted on the surface of the frame 17. The surface of the fixing plate 21 has a slot 22. The interior of the placement frame 17 has a clamping mechanism 23, which includes a clamping plate 231. A protective pad 232 is provided on the side of the clamping plate 231. A tension spring 233 is fixedly connected to the side of the clamping plate 231. A pull block 234 is fixedly connected to the side of the clamping plate 231. A sliding groove 235 is provided on the side of the placement frame 17. A magnet A 236 is fixedly mounted on the side of the placement frame 17. A magnet B 237 is fixedly mounted on the side of the fire extinguisher body 1. The hook 11 and the hanging hole 12... The interlocking connection is as follows: the pressing block 9 and the slide rod 13 are slidably connected; one end of the tension spring A14 is fixedly connected to the lower surface of the pressing block 9; the other end of the tension spring A14 is fixedly connected to the inner side of the pressing frame 8; one end of the tension spring B18 is fixedly connected to the side of the locking block 19; the locking block 19 and the locking groove 22 are slidably connected; the protective pad 232 is made of natural rubber; one end of the tension spring 233 is fixedly connected to the side of the clamping plate 231; the pull block 234 and the slide groove 235 are slidably connected; and the magnet A236 and the magnet B237 are attracted to each other.

[0028] In this embodiment, the pressing block 9 slides along the slide rod 13 within the pressing frame 8, overcoming the elastic force of the tension spring A14. This causes the connecting rope 10 to drive the hook 11 to engage with the hanging hole 12 on the pressing switch 2, thereby pulling the pressing switch 2 to achieve one-handed operation of the fire extinguisher without the need for two hands. The combination of the fixed frame 15, rotating block 16, placement frame 17, tension spring B18, and locking block 19 ensures that when the rotating block 16 drives the placement frame 17 to the appropriate position, the locking block 19, under the action of the tension spring B18, engages with the locking groove 22 of the fixed plate 21, fixing the placement frame 17 and facilitating the positioning and placement of the nozzle 4. Spraying can be performed without holding the nozzle 4, improving operational convenience and fire extinguishing efficiency. At the same time, the clamping mechanism 23 in the placement frame 17 moves the clamping plate 231 against the elastic force of the tension spring 233 by pulling the pull block 234. After placing the nozzle 4 between the clamping plates 231, the pull block 234 is released, and the tension spring 233 drives the clamping plate 231 to clamp the nozzle 4. The protective pad 232 made of natural rubber can prevent the nozzle 4 from being pinched. In addition, the magnet A236 on the side of the placement frame 17 and the magnet B237 on the side of the fire extinguisher body 1 attract each other, further enhancing the stability of the nozzle 4 and preventing it from shaking or shifting.

[0029] Example 2: As Figures 1-5 As shown, the surface of the grip 7 is covered with a sponge sleeve 24, and the surface of the pressing block 9 is provided with anti-slip texture 25. The sponge sleeve 24 is cylindrical.

[0030] In this embodiment, the cylindrical sponge sleeve 24 covering the surface of the handle 7 increases the contact area with the hand, and the soft sponge material effectively alleviates fatigue caused by prolonged holding, providing a comfortable grip experience for the user. The anti-slip texture 25 on the surface of the press block 9 increases the friction between the fingers and the press block 9, ensuring that the fingers are not prone to slipping when pressing, even when the hands are sweaty or the fire scene environment is humid. This allows the user to press the press block 9 more stably and accurately, thereby reliably controlling the start and stop of the fire extinguisher, further improving the user experience and operational safety of the fire extinguisher.

[0031] The working principle of this embodiment: When using this easy-to-operate fire extinguisher, press the handle with one hand. First, grasp the handle 7. The cylindrical sponge sleeve 24 on the surface of the handle 7 provides a comfortable grip. Before use, first pull out the safety pin 3 inside the press switch 2 to release the fire extinguisher from its locked state. Then, press the pressing block 9 inside the pressing frame 8 with your finger. The pressing block 9 overcomes the elastic force of the tension spring A14 and slides downward along the slide rod 13. At this time, the hook 11 at one end of the connecting rope 10 on the surface of the pressing block 9 moves down accordingly. The push-button switch 2 engages with the hanging hole 12 on its surface. Pulling the push-button switch 2 opens the fire extinguisher valve, and the nozzle 5 sprays extinguishing agent to extinguish the fire. This allows for one-handed operation of the push-button switch 2. When extinguishing a fire, the nozzle 4 and nozzle 5 on the upper surface of the fire extinguisher body 1 can be placed in the placement frame 17. The placement frame 17 is rotatably connected to the inside of the fixed frame 15 via a rotating block 16. The tension spring B18 and the locking block 19 inside the rotating block 16 are engaged with the groove of the fixing plate 21 on the surface of the fixed frame 15. The 22 mechanism, when the placement frame 17 is rotated to a certain position, can be fixed, allowing spraying without constantly holding the nozzle 4 during use, improving operational convenience and fire extinguishing efficiency. Simultaneously, the clamping mechanism 23 within the placement frame 17, by pulling the pull block 234, causes the clamping plate 231 to move against the elastic force of the tension spring 233. After placing the nozzle 4 between the clamping plates 231, releasing the pull block 234 causes the tension spring 233 to drive the clamping plate 231 to clamp the nozzle 4. The natural rubber protective pad 232 can... To prevent the nozzle 4 from being pinched, the amount of extinguishing agent sprayed can be flexibly adjusted by controlling the pressure of the pressing block 9 during the fire extinguishing process. After the fire is extinguished, the pressing block 9 is released, the tension spring A14 returns the pressing block 9 to its original position, the hook 11 disengages from the hanging hole 12, and the fire extinguisher valve is closed, completing the fire extinguishing operation. The cylindrical sponge sleeve 24 on the surface of the handle 7 increases the contact area with the hand, and the soft sponge material effectively relieves fatigue caused by prolonged holding, providing a comfortable grip experience for the user. The anti-slip texture 25 on the surface of the pressing block 9 increases the friction between the fingers and the pressing block 9, ensuring that the fingers are not slippery when pressing, even when the hands are sweaty or the fire scene is humid, allowing the user to press the pressing block 9 more stably and accurately.

Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
