Description

Technical Field

[0001] This utility model belongs to the field of fire-fighting tool technology, and in particular relates to a cat's eye fire hose. Background Technology

[0002] In fire emergencies involving severe indoor fires, where the situation inside is unclear and doors cannot be opened, forcibly opening them could result in a sudden burst of heat, posing a safety hazard to firefighters. In such situations, the usual approach is to spray water at the doorway to lower the temperature before breaking it open. However, modern doors have strong security and sealing mechanisms, so spraying water from the outside does not improve the situation inside.

[0003] In order to reduce the safety hazards for firefighters and effectively protect them during operations, firefighters discovered problems in actual situations and summarized their experiences. They believed that the peephole could be used as a breakthrough point. They could make a fire hose that could be inserted through the peephole to cool down and extinguish the fire in the indoor doorway area before breaking down the door. This would effectively reduce the danger of flames gushing out after the door is broken down. Utility Model Content

[0004] The purpose of this invention is to solve the problem of difficulty in cooling down the area near the doorway of a closed fire-prone room, and to provide a peephole fire hose that can be quickly inserted through the peephole of a security door to carry out rapid fire-fighting operations near the doorway.

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

[0006] Design a cat's eye fire hose, including a connecting pipe, one end of which is connected to a connecting sleeve, and the other end of which is provided with a connecting cylinder. The connecting cylinder is provided with multiple water outlet holes, and a sealing ring is fixedly connected inside the connecting cylinder. The sealing ring abuts against the connecting pipe, and the connecting cylinder and the connecting sleeve are fixed by a fixing mechanism.

[0007] Preferably, the fixing mechanism includes a threaded post, the threaded post having a thread that passes through the connecting pipe, and a rotating block fixedly connected to the threaded post.

[0008] Preferably, an abutment block is fixedly connected to the threaded post, and the diameter of the abutment block is larger than the diameter of the threaded post.

[0009] Preferably, a limiting groove is formed on the connecting cylinder, and a limiting strip is fixedly connected to the connecting cylinder, with the limiting strip slidably disposed within the limiting groove.

[0010] Preferably, the connecting cylinder, the threaded column, and the connecting pipe are all made of stainless steel.

[0011] Preferably, a rubber sleeve is fixedly connected to the rotating block.

[0012] The advantages of this utility model are: it is easy to use, can be quickly inserted through the peephole of the security door, and there is no problem with the operation of the technical difficulty; it is easy to operate, and the water supply can be connected using the fire hose on the floor to complete the fire operation; it is highly practical and efficient, and can effectively reduce the temperature of the indoor doorway, thereby reducing the danger and difficulty for firefighters to break down doors and carry out fire operations.

[0018] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0019] Example 1: Refer to Figure 1-4 A cat-eye fire hose includes a connecting pipe 3, one end of which is connected to a connecting sleeve 5, and the other end of which is provided with a connecting cylinder 1. The connecting cylinder 1 is provided with multiple water outlet holes 2. The connecting cylinder 1, the threaded column 8 and the connecting pipe 3 are all made of stainless steel to prevent corrosion.

[0020] A sealing ring 6 is fixedly connected inside the connecting cylinder 1, serving a sealing function. The sealing ring 6 abuts against the connecting pipe 3. The connecting sleeve 5 utilizes the floor's fire protection facilities, connecting to the floor's fire hydrant via a fire water pipe. The connecting cylinder 1 and the connecting sleeve 5 are fixed together by a fixing mechanism. Adjusting the position of the connecting cylinder 1 within the connecting pipe 3 and securing it through the fixing mechanism allows for adjustment of the overall length of the device. During operation, the device is inserted into the door through the peephole via the connecting cylinder 1. After the fire hydrant is turned on, water sprays out from the outlet hole 2 in an umbrella-shaped spray pattern, effectively cooling the area near the door. The fixing mechanism includes a threaded post 8, which is threaded through the connecting pipe 3. A rotating block 4 is fixedly connected to the threaded post 8, and a rubber sleeve is fixedly connected to the rotating block 4. Rotating the rotating block 4 causes the threaded post 8 to rotate, thereby releasing the fixing of the connecting cylinder 1.

[0021] Example 2: Refer to Figure 4 In another preferred embodiment of this utility model, based on embodiment 1, an abutment block 7 is fixedly connected to the threaded post 8. The diameter of the abutment block 7 is larger than the diameter of the threaded post 8. The abutment block 7 serves to limit the movement and prevent the threaded post 8 from dislodging from the threaded hole.

[0022] Example 3: Reference Figure 2 As another preferred embodiment of this utility model, based on embodiment 2, a limiting groove is provided on the connecting cylinder 1, and a limiting strip 9 is fixedly connected to the connecting cylinder 1. The limiting strip 9 is slidably disposed in the limiting groove. By using the limiting strip 9, the connecting cylinder 1 and the connecting pipe 3 are limited. When the limiting strip 9 is facing downward, it can be used as a reference for the position of the water outlet 2, so that the water outlet 2 faces upward when it is inserted.

[0023] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
