Description

Technical Field

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

[0002] Fire extinguishers are a common type of fire-fighting equipment, widely stored in public places or other places where fires may occur. There are various types of fire extinguishers, among which wheeled fire extinguishers have become an indispensable fire-fighting facility in some places because they are easy to move within a small area and can store a large amount of extinguishing agent.

[0003] However, existing wheeled fire extinguishers have some shortcomings. For example, most wheeled fire extinguishers have an L-shaped frame structure, with two wheels on one side of the bottom of the frame and support legs on the other side. However, because wheeled fire extinguishers have a large capacity, they are difficult to move. The frame must be tilted so that the support legs are raised before it can be moved, which is strenuous and puts a lot of pressure on the user's arms, making it very inconvenient to use. Therefore, the inventor believes that a more portable wheeled fire extinguisher should be designed. Utility Model Content

[0004] This application provides a portable wheeled fire extinguisher.

[0005] The wheeled fire extinguisher provided in this application adopts the following technical solution:

[0006] A wheeled fire extinguisher includes a wheelbarrow and a fire extinguisher movably mounted on the wheelbarrow. The lower end of the wheelbarrow is provided with wheels and support legs, which are located on the front and rear sides of the wheelbarrow, respectively. The wheelbarrow is provided with support legs, which are movably connected to the wheelbarrow and have auxiliary support wheels at their lower ends. The auxiliary support wheels can support the wheelbarrow simultaneously with the wheels.

[0007] Preferably, the trolley has a square frame, the lower end of the trolley is connected to the wheels, the lower end of the trolley has an L-shaped bend that supports the fire extinguisher, the front end of the L-shaped bend has a support leg that points downwards, the upper part of the trolley has a connecting hole and is rotatably connected to the support leg through the connecting hole, and the distance from the connecting hole to the wheels is greater than the length of the support leg.

[0008] Preferably, the outer side of the lower end of the handcart is connected to the walking wheel, and the support leg is a U-shaped frame with the upper end of the support leg connected to the inner side of the handcart.

[0009] Preferably, the trolley or the support leg is provided with a buckle, which can be engaged with the support leg or the trolley.

[0010] Preferably, a limiting rod is provided on the side of the connecting hole. The limiting rod is a horizontal rod and the inner side of the limiting rod can connect with the side of the support leg.

[0011] Preferably, the width of the handcart is smaller than the diameter of the fire extinguisher, and multiple adjustable locking clamps are provided at different heights of the handcart. One end of the adjustable locking clamp is rotatably connected to the handcart, and the other end of the adjustable locking clamp is wrapped around the handcart and is provided with a locking buckle.

[0012] In summary, this application includes at least one of the following beneficial technical effects:

[0013] 1. This application connects the fire extinguisher to the handcart, allowing for the replacement of used fire extinguishers and facilitating the reuse of the handcart. The handcart is equipped with support legs and auxiliary support wheels. During use, the fire extinguisher can be supported by the auxiliary support wheels in conjunction with the walking wheels, reducing pressure on the user's arms during movement and making it convenient to use.

[0014] 2. By designing the trolley with a square frame structure and connecting holes for rotating support legs, and ensuring the distance between the connecting holes and the traveling wheels is greater than the length of the support legs, the support legs can be folded up, reducing space requirements and facilitating use. Positioning the traveling wheels and auxiliary support wheels on the outer sides of the trolley and support legs respectively ensures balanced force distribution on both, facilitating movement. Buckles on the trolley or support legs allow for easy securing and storage of the support legs. Limiting rods on the sides of the connecting holes restrict the angle of the support legs, ensuring stable support during movement.

[0015] 3. By installing multiple adjustable locking clamps at different heights on the handcart, the stable connection of the fire extinguisher is ensured, and it is also convenient to remove and replace the used fire extinguisher. Attached Figure Description

[0020] The present application will be further described in detail below with reference to the accompanying drawings.

[0021] This application discloses a wheeled fire extinguisher.

[0022] Reference Figures 1 to 3 A wheeled fire extinguisher includes a wheeled cart 1 and a fire extinguisher 2 movably mounted on the wheeled cart 1. The wheeled cart 1 has a square frame. The lower end of the wheeled cart 1 is provided with wheels 3 and support legs 4, and the wheels 3 and support legs 4 are located on the front and rear sides of the wheeled cart 1, respectively. Specifically, the wheels 3 are connected to the outer side of the lower end of the wheeled cart 1. The lower end of the wheeled cart 1 has an L-shaped bend 101 that is forward-facing, which is used to support the fire extinguisher 2. The front end of the L-shaped bend 101 has a support leg 4 that is downward-facing, which is used to provide stable support.

[0023] Reference Figure 1 and Figure 2 The handcart 1 is equipped with a support leg 5, which is movably connected to the handcart 1. The lower end of the support leg 5 is equipped with an auxiliary support wheel 6, which can support the handcart 1 simultaneously with the traveling wheel 3. Specifically, in this embodiment, the upper part of the handcart 1 is provided with a connecting hole 102, and the support leg 5 is rotatably connected through the connecting hole 102. The distance from the connecting hole 102 to the traveling wheel 3 is greater than the length of the support leg 5. The support leg 5 is a U-shaped frame, and the upper end of the support leg 5 is connected to the inner side of the handcart 1. By setting the traveling wheel 3 and the auxiliary support wheel 6 on the outer side of the handcart 1 and the outer side of the support leg 5 respectively, it is ensured that the handcart 1 and the support leg 5 can be subjected to balanced force, which is convenient for movement. At the same time, the handcart 1 or the support leg 5 is provided with a buckle 7, which can be engaged with the support leg 5 or the handcart 1 for easy fixation. When not in use, the support leg 5 can be stored through the buckle 7.

[0024] Reference Figure 2 A limiting rod 103 is provided on the side of the connecting hole 102. The limiting rod 103 is a horizontal rod and the inner side of the limiting rod 103 can connect with the side of the support leg 5. The limiting rod 103 can limit the rotation angle of the support leg 5. In this embodiment, the included angle between the support leg 5 and the handcart 1 is an obtuse angle. The angle of the support leg 5 is maintained by the weight of the fire extinguisher to ensure stable support.

[0025] Reference Figures 1 to 3 The width of the handcart 1 is smaller than the diameter of the fire extinguisher 2. Multiple adjustable locking clamps 8 are provided at different heights of the handcart 1. One end of the adjustable locking clamp 8 is rotatably connected to the handcart 1, and the other end of the adjustable locking clamp 8 is wrapped around the handcart 1 and is provided with a locking buckle.

[0026] The implementation principle is as follows: This application connects the fire extinguisher 2 to the handcart 1 in a movable manner, so that the used fire extinguisher 2 can be replaced and the handcart 1 can be reused. At the same time, the handcart 1 is equipped with a support leg 5 and an auxiliary support wheel 6. When in use, the fire extinguisher 1 can be supported by the auxiliary support wheel 6 in combination with the walking wheel 3, which reduces the pressure on the arms of the personnel when moving and makes it convenient to use.

[0027] 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.
