Description

Technical Field

[0001] This utility model relates to the field of fire extinguishing device technology, specifically a multifunctional handheld fire extinguishing device. Background Technology

[0002] A fire extinguisher is a portable fire-fighting tool containing chemicals such as foam, dry powder, halon, and carbon dioxide. Most are manual fire extinguishers and are usually stored in places where fires may occur, making them easily accessible to the public in case of an emergency. To extinguish a fire, the operator pulls out the safety pin on the fire extinguisher, holds the handle with one hand and the nozzle with the other, and presses the pressure plate above the handle, aiming at the base of the flame.

[0003] According to a search, Chinese patent document CN221845914U discloses a portable fire extinguishing device. It features a placement basket and a movable base plate. A support rod pulls the movable base plate, which directly moves the placement basket and the fire extinguisher itself, facilitating the carrying and transport of the fire extinguisher. A connector that slides up and down on the support rod moves the placement basket along with it. A positioning component that slides inside the support rod's groove positions the placement basket, supporting the fire extinguisher at a suitable extinguishing height during use, improving the flexibility of the portable fire extinguishing device and saving operator effort. However, while the placement basket can limit the fire extinguisher's position, it cannot securely hold different sizes of fire extinguishers, leading to easy shaking and impacts during transport, as well as noise and vibration affecting transport efficiency. Furthermore, although the height of the fire extinguisher can be adjusted, continuous manual operation by holding the hose during extinguishing still results in significant physical exertion and poor usability.

[0027] Example 1:

[0028] like Figure 1-4 As shown, the present invention provides a multifunctional handheld fire extinguishing device, including a base 1, a support frame 2 fixedly installed on the upper right side of the base 1, a cylinder 3 provided on the top side of the support frame 2, an adjusting plate 4 fixedly installed on the bottom end of the cylinder 3, a threaded rod 5 provided on the inner side of the adjusting plate 4, and a clamping seat 6 connected to the outer side of the threaded rod 5 by a thread. A fixing seat 7 is fixedly installed on the right side of the base 1, a fixing frame 8 is movably installed on the right side of the fixing seat 7, a caster wheel 9 is provided on the bottom side of the base 1, and a handle 10 is fixedly installed on the upper left side of the base 1.

[0029] Specifically, four limiting holes 201 are provided on the top side of the support frame 2, which are equidistantly arranged at the four corners of the top side of the support frame 2. Three lighting lamps 202 are fixedly installed on the right side of the support frame 2, arranged in a rectangular equidistant structure. The advantages are that the limiting holes 201 facilitate the orientation and limiting of the adjusting plate 4, improving the stability of its movement, and the three equidistantly arranged lighting lamps 202 provide illumination during use, thereby improving ease of use.

[0030] Specifically, a limiting rod 401 is fixedly installed on the top side of the adjusting plate 4. The limiting rod 401 is movably installed inside the limiting hole 201. A receiving groove 402 is provided on the bottom side of the adjusting plate 4. A threaded rod 5 is movably installed inside the receiving groove 402 via a bearing. A handle 403 is fixedly installed at the rear end of the threaded rod 5. The advantage is that rotating the handle 403 drives the threaded rod 5 to rotate, which facilitates the movement of the two sets of clamping blocks 602, thereby facilitating the fixing of the fire extinguisher's pipe opening. Moreover, the movement of the limiting rod 401 inside the limiting hole 201 improves the stability when adjusting the fire extinguishing height.

[0031] Specifically, the clamping seat 6 includes a threaded sleeve 601 and a clamping block 602. The threaded sleeve 601 is threadedly connected to the outside of the threaded rod 5, and the clamping block 602 is fixedly installed on the bottom side of the threaded sleeve 601. The clamping seat 6 has a total of two sets, and the clamping blocks 602 have grooves on opposite sides. The advantage is that by rotating the threaded rod 5, the threaded sleeve 601 can easily drive the corresponding clamping block 602 to move and clamp and fix the pipe opening of the fire extinguisher, thereby replacing the difficulty of manual handling and facilitating the simultaneous extinguishing of multiple fire extinguishers.

[0032] Example 2:

[0033] like Figure 1-4 As shown, this is an improvement on the previous embodiment. Specifically, a cavity 701 is provided on the right side of the fixing base 7. A connecting shaft 702 is fixedly installed inside the cavity 701, and a fixing frame 8 is movably installed on the outside of the connecting shaft 702. A torque spring 703 is provided between the fixing frame 8 and the cavity 701. A total of two sets of fixing bases 7 are provided. The advantage is that the connecting shaft 702 facilitates the limiting of the fixing frame 8, thereby improving rotational stability. Furthermore, under the action of the torque spring 703, it is convenient to drive the fixing frame 8 to move synchronously towards the fire extinguisher for reset and reinforcement.

[0034] Specifically, the fixing frame 8 includes a first clamping plate 801, a second clamping plate 802, and connecting columns 803. Two connecting columns 803 are fixedly installed between the first clamping plate 801 and the second clamping plate 802. The first clamping plate 801 and the second clamping plate 802 have an arc-shaped structure, and a total of two sets of fixing frames 8 are provided. The advantage is that by pulling out the fixing frame 8 after the fire extinguisher has been used, and then pressing and engaging the new fire extinguisher with the two sets of fixing frames 8, the first clamping plate 801 and the second clamping plate 802 move synchronously towards the fire extinguisher under the action of the torque spring 703 to clamp and fix it. The installation is convenient and quick, and it is also convenient to install and fix fire extinguishers of different sizes, avoiding damage caused by bumps or collisions during transportation or increasing the difficulty of transportation.

[0035] In use, pulling the handle 10 facilitates the transport and movement of the fire extinguisher using the casters 9. During use, placing the fire extinguisher's nozzle inside the groove between the two clamping blocks 602 and then turning the handle 403 rotates the threaded rod 5, allowing the two clamping blocks 602 to move relative to each other and clamp and secure the fire extinguisher's nozzle. This eliminates the difficulty of manual handling and allows for simultaneous extinguishing of multiple fire extinguishers. The cylinder 3 then activates the adjusting plate 4 to raise or lower the extinguishing height, facilitating easy adjustment of the extinguishing height. The fire extinguisher is repeatedly raised and lowered for fire suppression, and the lighting 202 provides convenient illumination, improving ease of use. When the fire extinguisher needs to be replaced, the used fire extinguisher is pulled out of the fixing bracket 8, and then the new fire extinguisher is pressed and locked with the two fixing brackets 8. Then, under the action of the torque spring 703, the first clamp 801 and the second clamp 802 move towards the fire extinguisher simultaneously for clamping and fixing. The installation is convenient and quick, and it is also convenient to install and fix fire extinguishers of different specifications, avoiding damage or increased transportation difficulties caused by bumps during transportation.
