Description

Technical Field

[0001] This utility model relates to the field of storage for nylon hoses of wheeled dry powder fire extinguishers, and particularly to a storage device for nylon hoses of wheeled dry powder fire extinguishers. Background Technology

[0002] Dry powder extinguishing agents are dry and easily flowing fine powders used for fire extinguishing. They are composed of fine solid powders made by drying, pulverizing, and mixing inorganic salts with fire extinguishing properties and a small amount of additives. Dry powder extinguishing agents are widely used in fire fighting and are mainly used in fire extinguishers.

[0003] Currently, the nylon hose of wheeled dry powder fire extinguishers is 4m long. When the fire extinguisher is in standby mode, the nylon hose needs to be folded more than ten times before being placed on the bracket or wrapped around the frame. After repeated folding, the nylon hose is prone to twisting and bending when pulled out for use, which affects operation. Moreover, the nylon hose is exposed for a long time, and the folded part of the nylon hose is prone to aging and breakage. Utility Model Content

[0004] The purpose of this invention is to overcome the shortcomings of existing technologies, such as the tendency of nylon hoses to break when repeatedly folded during fire extinguisher standby and the tendency of nylon hoses to bend and twist when pulled out for use. This invention provides a storage device for nylon hoses of wheeled dry powder fire extinguishers.

[0005] A storage device for the nylon hose of a wheeled dry powder fire extinguisher, comprising:

[0006] Support frame for connecting to wheeled dry powder fire extinguishers;

[0007] A storage tray for winding nylon hoses, the storage tray being rotatably connected to the support frame, and a positioning element provided on the storage tray for limiting the nylon hose;

[0008] A grip for rotating the storage tray, the grip being connected to the storage tray.

[0009] This utility model discloses a storage device for nylon hoses in wheeled dry powder fire extinguishers. It is fixed to the wheeled dry powder fire extinguisher via a support member, and a positioning member positions the nylon hose, allowing it to wind around the storage tray as it rotates. The storage tray is rotatably mounted on a support frame; the relative rotation between the storage tray and the support frame reduces the number of folds, thus slowing down aging and breakage. The rotation of the storage tray on the support frame allows the nylon hose to be quickly pulled out during use, preventing twisting and bending. A grip allows the operator to easily push the storage tray to rotate, facilitating the winding of the nylon hose.

[0010] Preferably, the support frame is detachably connected to the frame of the trolley-type dry powder fire extinguisher.

[0011] The storage device for the nylon hose of wheeled dry powder fire extinguishers can be used on existing wheeled dry powder fire extinguishers.

[0012] Preferably, the support frame is provided with a clamp, which can hold the trolley-type dry powder fire extinguisher to the frame.

[0013] The support frame is fixed to the frame of the wheeled dry powder fire extinguisher by clamping it with a clamp. The support frame is located on one side of the storage tray, and the handle and the support frame are located on the two sides of the storage tray, which makes it easy for the operator to hold the handle and rotate the storage tray. Multiple clamps can be set to enhance the fixing effect of the support frame.

[0014] Preferably, the support frame is provided with a rotating shaft, which passes through the center of the storage tray, and the storage tray is rotatably connected to the rotating shaft.

[0015] By rotating the shaft through the center of the storage tray, the storage tray rotates around its center, allowing it to rotate at a uniform and stable speed. This facilitates the winding of the nylon hose onto the storage tray and makes it easy for operators to control the rotation speed and position of the storage tray.

[0016] Preferably, the storage tray is provided with a bearing component, and the rotating shaft is connected to the bearing component.

[0017] A through hole is provided in the center of the storage tray. The bearing is fitted into the through hole and connected to the bearing through a rotating shaft. The easy rotation of the bearing makes it easier for operators to operate, reduces wear on the storage tray, and improves its durability.

[0018] Preferably, the storage tray has an annular groove along the circumference of the storage tray, and the positioning member is disposed in the annular groove, which is used to store nylon hoses.

[0019] The nylon hose can be wound into an annular groove, with the width of the annular groove being slightly larger than the width of the nylon hose in its flat state. This ensures that the nylon hose can be wound flat, allowing operators to quickly store the nylon hose.

[0020] Preferably, the gripping member includes a columnar structural member, which is parallel to the rotation axis and offset from the rotation axis, and the end of the columnar structural member is connected to the storage tray.

[0021] The operator pushes the columnar structural component to make the storage tray rotate around the rotating shaft.

[0022] Preferably, a sleeve is fitted onto the columnar structural member, and the sleeve is rotatably connected to the columnar structural member.

[0023] The operator holds the sleeve and pushes it to rotate the storage tray. The columnar structural component rotates inside the sleeve, making it easier for the operator to rotate the storage tray.

[0024] Preferably, the support frame is provided with a limiting member, which is used to limit and fix the storage tray.

[0025] The limiting component is a pin. By inserting the pin into the storage tray, the pin limits the storage tray and prevents the storage tray from rotating. This prevents the nylon hose from falling off the storage tray after it has been stored because the storage tray rotates freely.

[0026] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0027] 1. This utility model discloses a storage device for nylon hoses in wheeled dry powder fire extinguishers. The device is fixed to the wheeled dry powder fire extinguisher via a support member, and a positioning member secures the nylon hose, allowing it to wind around the storage tray as it rotates. The storage tray is rotatably mounted on a support frame. The relative rotation of the storage tray and the support frame reduces the number of folds in the nylon hose, thus slowing down aging and breakage. The rotation of the storage tray on the support frame allows for quick and easy pulling out of the nylon hose during use, preventing twisting and bending. A gripping member facilitates the operator's ability to push the storage tray to rotate, making it easy to wind the nylon hose.

[0028] 2. This utility model provides a storage device for nylon hoses of wheeled dry powder fire extinguishers. By winding the nylon hose onto a storage tray, the device can store the nylon hose while reducing folding and thus minimizing damage. When the nylon hose is pulled out from the storage tray, it avoids twisting and bending, allowing the nylon hose to be put into use quickly. This device has good economic and practical value.

[0044] A storage tray 4 for winding nylon hose 11, the storage tray 4 is rotatably connected to the support frame 8, and a positioning element 3 is provided on the storage tray 4 for limiting the nylon hose 11.

[0045] A grip 5 is used to drive the storage tray 4 to rotate, and the grip 5 is connected to the storage tray 4.

[0046] The nylon hose 11 is fixed to the wheeled dry powder fire extinguisher by connecting to the support member. The positioning member 3 can hold and fix the nylon hose 11, so that the nylon hose 11 can be wound around the storage tray 4 as it rotates. The storage tray 4 is rotatably set on the support frame 8. By rotating the storage tray 4 relative to the support frame 8, the nylon hose 11 is wound around the storage tray 4, which can reduce the number of times the nylon hose 11 is folded, thereby slowing down the aging and breakage of the nylon hose 11. By using the storage tray 4 to rotate on the support frame 8, the nylon hose 11 can be quickly pulled out when used, avoiding twisting and bending when the nylon hose 11 is pulled out. The grip member 5 makes it easy for the operator to push the storage tray 4 to rotate, which is convenient for winding the nylon hose 11.

[0047] In one or more embodiments, the support frame 8 is detachably connected to the frame 12 of the wheeled dry powder fire extinguisher, and the storage device for the nylon hose of the wheeled dry powder fire extinguisher can be installed on the existing frame 12 of the wheeled dry powder fire extinguisher. In some embodiments, the support frame 8 is welded to the frame 12 of the wheeled dry powder fire extinguisher.

[0048] In an optional embodiment, the support frame 8 is provided with a clamp 1, which can be clamped and connected to the frame 12 of the wheeled dry powder fire extinguisher. The clamp 1 can be quickly installed and fixed on the frame 12. The end of the clamp 1 is provided with a fixing member, which clamps the clamp 1 to form a ring structure. Utilizing the adjustable clamping range of the clamp 1, the clamp 1 can be adapted to different frames 12 for fixing. Multiple clamps 1 are provided on the support frame 8, and there is a gap between adjacent clamps 1. By clamping and fixing multiple clamps 1 at different positions on the frame 12, the stability of the support frame 8 is improved.
