Description

Technical Field

[0001] This application relates to the field of fire extinguisher technology, and in particular to a hose-supported wheeled fire extinguisher. Background Technology

[0002] Wheeled fire extinguishers are portable and powerful fire-fighting equipment, mainly composed of an extinguishing agent tank, nozzle, pressure gauge, and wheeled support. They are suitable for extinguishing solid, liquid, gas, and electrical fires. Common types include dry powder, carbon dioxide, and water-based types. They are characterized by their ability to be quickly pushed to the fire source and are suitable for warehouses, workshops, parking lots, and other places. They are an important fire-fighting tool in public places and industrial areas.

[0003] Wheeled fire extinguishers usually require two people to operate. One person pulls out the safety pin and presses the handle, while the other person approaches the fire source and sprays the nozzle at the base of the flames. If only one person is operating it, the operator needs to bring the wheeled fire extinguisher close to the fire source, press the handle with one hand, and aim the nozzle at the fire source with the other hand. If the fire is large, the hand holding the nozzle may be burned due to its proximity to the fire source. Utility Model Content

[0004] This application provides a trolley-type fire extinguisher that can be supported by a hose.

[0005] The present application provides a flexible, supportable wheeled fire extinguisher with the following technical solution:

[0006] A hose-supported wheeled fire extinguisher includes a base, a cylinder and a mounting bracket on the base, a valve connected to the upper end of the cylinder, a hose connected to the outlet of the valve, and a first bracket and a second bracket. The first bracket is connected to the base, and the second bracket is connected to the end of the first bracket away from the base and located below the outlet of the valve and extending away from the valve. A groove is formed on the upper surface of the second bracket along its length, and the hose is distributed parallel to the second bracket and disposed within the groove.

[0007] Preferably, the first frame and the second frame are rotatably connected, and a support rod is rotatably connected to the first frame. The second frame has a plurality of positioning holes along the length of the second frame on the side opposite to the groove, and the end of the support rod is connected to one of the positioning holes.

[0008] Preferably, the first frame has a mounting groove that matches the second frame, and female buckles are provided on both sides of the mounting groove;

[0009] The support rod is provided with a female buckle that matches the female buckle.

[0010] Preferably, the base is provided with casters at the bottom and a handle at the top.

[0011] Preferably, the valve is connected to a lifting handle and a pressing handle, the lifting handle is located below the pressing handle and is connected to the handle, and extension rods are provided on both sides of the pressing handle, the extension rods being parallel to the top of the handle.

[0012] Preferably, a hose buckle is connected to the second frame, and the hose buckle is arranged around the hose.

[0013] In summary, this application includes at least one of the following beneficial technical effects:

[0014] 1. This application, by setting up an installation rack, allows the hose to be aimed at the fire source without holding it, thus preventing the user from being burned by the flames. It also allows for flexible adjustment of the hose's direction to deal with various fire conditions. When not in use, the installation rack can be stored away, saving space.

[0015] 2. By installing an extension rod on the handle, the user can press the extension rod to activate the fire extinguishing agent hose, which is more convenient and less strenuous than pressing the handle in the existing technology. Attached Figure Description

Detailed Implementation

[0019] The present application will be further described in detail below with reference to the accompanying drawings.

[0020] This application provides a hose-supported wheeled fire extinguisher, such as... Figure 1 and Figure 2As shown, the device includes a base 1, on which a bottle body 2 and a mounting bracket 3 are mounted. A valve 4 is connected to the upper end of the bottle body 2, and a handle 11 and a pressure handle 12 are connected to the valve 4. The handle 11 is located below the pressure handle 12. The structure of the handle 11 and the pressure handle 12 is the conventional setting of fire extinguishers in the prior art, and will not be described in detail here. A hose 5 is connected to the outlet of the valve 4. The operator can press the pressure handle 12 to spray the extinguishing agent in the bottle body 2 through the hose 5, thereby achieving the effect of extinguishing the fire. The bottom of the base 1 is equipped with casters 9, and the top is equipped with a handle 10. The handle 11 is connected to the handle 10. Extension rods 13 are provided on both sides of the pressure handle 12. The extension rods 13 are parallel to the top of the handle 10. The user can press the extension rods 13 to urge the extinguishing agent to spray out of the hose 5. Compared with the method of pressing the pressure handle 12 in the prior art, the operation is more convenient and less strenuous.

[0021] The mounting bracket 3 includes a first bracket 31 and a second bracket 32. The first bracket 31 is connected to the base 1. The second bracket 32 ​​is rotatably connected to the end of the first bracket 31 away from the base 1 and is located below the outlet of the valve 4 and extends away from the valve 4. A groove 321 is formed on the upper surface of the second bracket 32 ​​along its length. The flexible hose 5 is distributed parallel to the second bracket 32 ​​and is disposed in the groove 321. A flexible hose buckle 14 is connected to the second bracket 32 ​​and surrounds the flexible hose 5. A support rod 6 is also rotatably connected to the first bracket 31. Multiple positioning holes 322 are opened on the side of the second bracket 32 ​​facing away from the groove 321 along its length. The end of the support rod 6 is connected to one of the positioning holes 322. The first bracket 31 forms a mounting groove 311 that matches the second bracket 32. Female buckles 7 are provided on both sides of the mounting groove 311. Female buckles 8 that match the female buckles 7 are provided on the support rod 6.

[0022] The working principle of the flexible hose-supported wheeled fire extinguisher of this application is as follows: Adjusting the universal wheels 9 via the handle 10 adjusts the overall position of the wheeled fire extinguisher. Rotating the second frame 32 aligns the outlet end of the hose 5 with the fire source. Then, rotating the support rod 6 allows its end to pass through a suitable positioning hole 322, fixing the second frame 32 in a position where the hose 5 can be aligned with the fire source. Finally, pressing the extension rod 13 towards the handle 10 allows both hands to hold the handle 10 while pressing the extension rod 13. If the fire source position changes, the flexible hose extinguisher can be adjusted by rotating the universal wheels 9 via the handle 10. After extinguishing the fire, move the support rod 6 out of the positioning hole 322 and rotate it in the direction close to the base 1 to make room for the second frame 32 to rotate. The second frame 32 rotates in the direction close to the mounting groove 311 until it is embedded in the mounting groove 311. Then rotate the support rod 6 so that the male buckle 8 is fastened to the female buckle 7, thus completing the storage of the mounting frame 3. Compared with the prior art, this application can make the hose 5 aim at the fire source without holding the hose 5, avoiding burns to the user. It can also flexibly adjust the direction of the hose 5 to deal with various fire situations. When not in use, the mounting frame 3 can also be stored, saving space.

[0023] The above are all preferred embodiments of this application, and are not intended to limit the scope of protection of this application. Therefore, all equivalent changes made in accordance with the structure, shape and principle of this application should be covered within the scope of protection of this application.
