[0002] In modern society, fire safety is of paramount importance, and fire hazards are widespread in various places, such as factories, warehouses, shopping malls, and vehicles. Fire extinguishers, as a basic and crucial firefighting device, play an irreplaceable role in the initial stages of fire suppression. They can respond quickly, promptly contain the spread of fire, buy valuable time for evacuation and fire rescue, and effectively reduce the losses caused by fire.

[0003] Existing fire extinguisher fixing devices are often designed in a simple way, usually using a matching iron limiting strip to frame the fire extinguisher and limit its position. This fixing method is difficult to adapt to fire extinguishers of different sizes, and after long-term use, the iron limiting strip will rust or even break. At this time, the limiting strip needs to be re-welded, and the process of replacing the limiting strip is cumbersome, increasing the intensity of the work and reducing the efficiency of the staff in maintaining the device. In order to address this technical problem, this application proposes a mobile fire extinguisher. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing a portable fire extinguisher. By rotating the rotating rod, the sleeve can be rotated, thereby retracting the strap to secure the extinguisher body of different sizes. This ensures the extinguisher remains stable under various working conditions, greatly improving the device's versatility and practicality. The design also prioritizes ease of maintenance, with strap replacement being extremely simple. By unscrewing the top cover, removing the sleeve from the sleeve, and then unscrewing the limiting block to remove the other end of the strap, the strap can be easily removed. This simple disassembly method facilitates the replacement of damaged straps and significantly improves the efficiency of strap replacement.

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

[0006] A portable fire extinguisher includes a base plate, with the extinguisher body mounted on top of the base plate. Wheels are mounted on both the left and right ends of the base plate. A back plate is fixedly connected to the rear end of the base plate, and a fixed cylinder is fixedly connected to the rear end of the back plate. A sleeve is rotatably connected to the middle of the fixed cylinder. A sleeve is fitted onto the outer wall of the sleeve, and a strap is fixedly connected to the outer wall of the sleeve. A limit rod is connected to the other end of the strap. A fixed support rod is fixedly connected to the bottom end of the limit rod. The fixed support rod is fixedly connected to the rear end of the back plate. An upper locking pad is fixedly connected to the bottom end of the sleeve, and a lower locking pad is located at the bottom of the upper locking pad. A reset component is located in the middle of the lower locking pad.

[0007] Furthermore, the reset assembly includes a limiting post slidably connected in the middle of the lower locking pad, one end of which is fitted with a spring and connected to the bottom of the lower locking pad, and the other end of which is connected to the bottom inner wall of the fixed cylinder.

[0008] Furthermore, the fixed cylinder is provided with a top cover, and a rotating rod is provided in the middle of the top cover. The bottom end of the rotating rod is fixedly connected to the top end of the sleeve rod.

[0009] Furthermore, a bottom block is fixedly connected to the bottom front end of the base plate.

[0024] 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.

[0025] Reference Figure 1-3This utility model provides an embodiment of a portable fire extinguisher, including a base plate 1. The top of the base plate 1 is equipped with a fire extinguisher body 5. Wheels are provided at both ends of the base plate 1, allowing the fire extinguisher body 5 to be moved easily. A back plate 2 is fixedly connected to the rear end of the base plate 1, providing support for the fire extinguisher body 5. A fixing cylinder 7 is fixedly connected to the rear end of the back plate 2. The outer wall of the fixing cylinder 7 has a first moving groove for a strap 6 to pass through, and the bottom outer wall of the fixing cylinder 7 has a second moving groove adapted to the size of the handle 12. A sleeve rod 15 is rotatably connected to the middle of the fixed cylinder 7. A limiting groove is formed on the outer wall of the sleeve rod 15. A sleeve 14 is fitted onto the outer wall of the sleeve rod 15. A limiting strip that matches the limiting groove is fixedly connected to the inner wall of the sleeve 14. By rotating the sleeve rod 15, the sleeve 14 can be rotated, thereby winding the strap 6 through the sleeve 14. The strap 6 is fixedly connected to the outer wall of the sleeve 14. The other end of the strap 6 is connected to a limiting rod 13, which can fix the other end of the strap 6. A fixing support rod 8 is fixedly connected to the bottom end of the limiting rod 13. Rod 8 is fixedly connected to the rear end of back plate 2. An upper locking pad 16 is fixedly connected to the bottom end of sleeve rod 15. A lower locking pad 17 is located at the bottom of the upper locking pad 16. When the bottom surface of the upper locking pad 16 and the top surface of the lower locking pad 17 are in contact, sleeve rod 15 cannot rotate, thus securing the strap 6. When the bottom surface of the upper locking pad 16 and the top surface of the lower locking pad 17 are not in contact, sleeve rod 15 can rotate, allowing the strap 6 to be wound up by rotating sleeve rod 15. A limiting post is slidably connected to the middle of the lower locking pad 17. 19. The outer wall of the limiting post 19 is fixedly connected to the limiting strip 2. The inner wall of the lower locking pad 17 is provided with a limiting groove 2 that matches the size of the limiting strip 2. This setting can prevent the upper locking pad 16 from rotating with the lower locking pad 17, thereby achieving the effect of preventing the sleeve rod 15 from rotating. One end of the spring 18 is sleeved on the outer wall of the limiting post 19 and connected to the bottom of the lower locking pad 17. The other end of the spring 18 is connected to the bottom inner wall of the fixed cylinder 7. The spring 18 can reset the lower locking pad 17, thereby making it contact the upper locking pad 16.

[0026] Reference Figure 4-6The fixed cylinder 7 is equipped with a top cover 10. The bottom outer wall of the top cover 10 and the top inner wall of the fixed cylinder 7 are both provided with matching threaded grooves. A rotating rod 11 is located in the middle of the top cover 10. The rotating rod 11 not only provides a limit for the rotation of the sleeve rod 15, but also allows the sleeve rod 15 to rotate by rotating the rotating rod 11. The bottom end of the rotating rod 11 is fixedly connected to the top end of the sleeve rod 15. A bottom block 4 is fixedly connected to the front end of the bottom of the base plate 1, providing support for the front end of the base plate 1 and preventing the entire device from tipping over. Handles 3 are fixedly connected to both ends of the back plate 2, allowing personnel to easily move the fire extinguisher body 5. A pull handle 12 is rotatably connected to the outer wall of the lower locking pad 17, allowing the lower locking pad 17 to move downwards by pulling the pull handle 12. The top of the limiting rod 13 is provided with a limiting block 9. The inner wall of the limiting block 9 and the outer wall of the top of the limiting rod 13 are both provided with matching threaded grooves. By screwing the limiting block 9 to the top of the limiting rod 13, the other end of the strap 6 can be limited, preventing the other end of the strap 6 from coming off the limiting rod 13.

[0027] Working principle: First, place the fire extinguisher body 5 on the base plate 1 and unscrew the top cover 10. Then, put the sleeve 14 onto the sleeve rod 15, and screw the top cover 10 onto the sleeve rod 15. Next, put the other end of the strap 6 onto the limiting rod 13, and screw the limiting block 9 onto the limiting rod 13. This completes the installation of the strap 6. The strap 6 can also be replaced through the above operation. When the strap 6 needs to be tightened, first pull the lower locking pad 17 downwards using the pull handle 12, so that the top surface of the lower locking pad 17 is in contact with the upper locking pad. The bottom surface of block 16 is detached, and the spring 18 is compressed by the lower locking pad 17. Then, the rotating rod 11 rotates the sleeve rod 15, thereby winding the strap 6 through the sleeve rod 15. After releasing the handle 12, the spring 18 causes the lower locking pad 17 to return to its original position, so that the top surface of the lower locking pad 17 contacts the bottom surface of the upper locking pad 16, thereby limiting the sleeve rod 15 and preventing its rotation. This ensures that the strap 6 can limit the movement of the fire extinguisher body 5 and prevent the fire extinguisher body 5 from shifting.

[0028] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
