Description

Technical Field

[0001] This utility model relates to the technical field of fire-fighting equipment, specifically to a fire hose fixing device. Background Technology

[0002] During firefighting in multi-story buildings, a stable water supply to fire hoses is a critical factor determining firefighting efficiency and the safety of rescue personnel. Because the weight and pressure of fire hoses increase dramatically when filled with water, and they are subject to external forces such as being stepped on or dragged during firefighting, they are highly susceptible to displacement or detachment, leading to water supply interruptions and missed opportunities. Therefore, reliable fire hose securing devices are essential to ensuring the continuity of the water supply line.

[0003] Currently, the traditional fire hose securing devices widely used in the fire protection field mainly consist of a hook body (such as a double hook) and a fixing component (such as a rope). In practical applications, firefighters need to hook the hook onto the pull ring next to the hose connector, and then use the rope to find existing fixed bases such as doors, windows, and railings on site for securing. However, this traditional method has significant limitations: First, its installation is severely restricted by the site environment, making it difficult to implement in complex or open terrain lacking reliable fixed bases (such as large factories or collapse sites); second, its load-bearing capacity and reliability are insufficient, as the rope used for securing is easily eroded and broken when exposed to high temperatures in a fire for a long time, and the hook may also soften and deform due to high temperatures, posing a risk of failure; third, this device generally lacks an effective locking and anti-detachment structure, relying solely on a simple hook-hanging method, making it extremely easy for the hose to fall off the suspension point or the hose when subjected to strong pulling or external impact, thus compromising the stability of the water supply.

[0004] To overcome the aforementioned problems, Chinese patent application CN204275364U proposes an F-type quick-fixing device for water hoses. This design integrates hose fixing and support functions through an F-shaped main frame, aiming to reduce reliance on independent ropes and simplify operation. However, this device still has significant drawbacks: First, its "F-type" structure is essentially still an open hook, failing to fundamentally solve the problem of lack of locking, and the hose interface still risks detachment under multi-directional external forces; second, this structure may cause unnatural bending of the hose, increasing head loss and affecting the output pressure. Utility Model Content

[0005] The purpose of this invention is to provide a fire hose fixing device with self-locking and anti-detachment functions to improve the reliability and efficiency of fire fighting operations.

[0006] To achieve the above objectives, this application provides a fire hose fixing device, comprising: The U-shaped frame has its open end facing downwards. The U-shaped frame has a first side and a second side that are arranged opposite to each other. The inner wall of the top of the U-shaped frame and the inner wall of the first side together define an abutment surface for fitting against the wall. The second side of the U-shaped frame has a threaded hole that penetrates its inner and outer surfaces.

The upper and lower ends of the connecting pipe are respectively provided with an outlet and an inlet. A first connector, one end of which is connected to the water outlet, and the other end of which is used to connect to a water hose; The second connector has one end connected to the water inlet and the other end used to connect to the water hose.

[0007] As a preferred technical solution, the fixing component includes: an abutment, a screw, and a handwheel. The screw passes through the threaded hole, and the abutment and the handwheel are respectively fixed at both ends of the screw. The abutment is used to abut against the wall.

[0014] As a preferred technical solution, the connecting pipe and the U-shaped frame are connected by welding.

[0015] The fire hose fixing device provided by the above technical solution has the following advantages compared with the prior art: In use, the wall and the contact surface on the U-shaped frame are first brought into contact, and then the fixing component is rotated so that the end of the fixing component abuts against the wall, thus achieving a fixed connection between the device and the wall and forming a stable structure to prevent detachment.

[0023] The specific embodiments of this utility model will be further described in detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit the scope of this utility model.

[0024] Please see Figure 1 The fire hose fixing device provided in this application embodiment includes: a U-shaped frame 1, a fixing component 2, a connecting pipe 3, a first connecting member 4, and a second connecting member 5; The U-shaped frame 1 has its open end facing downwards. The U-shaped frame 1 has a first side 14 and a second side 15 that are arranged opposite to each other. The top inner wall of the U-shaped frame 1 and the inner wall of the first side 14 together define an abutment surface 11 for fitting against the wall 7. The second side 15 of the U-shaped frame 1 has a threaded hole 12 that penetrates its inner and outer surfaces. The fixing component 2 passes through the threaded hole 12 and is used to abut against the wall 7, and the fixing component 2 is screwed to the U-shaped frame 1; The connecting pipe 3 is arranged along the top of the U-shaped frame 1 and the outer wall of the first side 14, and the connecting pipe 3 is fixedly connected to the U-shaped frame 1. The upper and lower ends of the connecting pipe 3 are respectively provided with an outlet 31 and an inlet 32. One end of the first connector 4 is connected to the water outlet 31, and the other end is used to connect to the water hose; One end of the second connector 5 is connected to the water inlet 32, and the other end is used to connect to the water hose.

[0025] In this embodiment, during specific operation, the contact surface 11 of the U-shaped frame 1 is first placed against the wall 7 or windowsill. The fixing component 2 is adjusted according to the thickness of the windowsill or wall 7 to ensure the end of the fixing component 2 is tightly against the windowsill or wall 7, thus fixing the device to the wall 7 or windowsill. Then, the two sections of water hose are connected to the inlet 32 ​​and outlet 31 of the connecting pipe 3, respectively. The water hose and connecting pipe 3 are then fixedly connected via the second connector 5 and the first connector 4, allowing water to be supplied for fire extinguishing. This device is simple to operate. By using a connecting pipe 3 that conforms to the shape of the outer wall of the U-shaped frame 1 to transport fire-fighting water, it avoids direct hose transport, preventing hose bending and friction between the hose and the wall 7 or windowsill, thus extending the hose's service life. Furthermore, the overall structure of this device is simple, easy to carry and install, and highly practical.

[0026] In some embodiments, the fixing component 2 includes an abutment 21, a screw 22, and a handwheel 23. The screw 22 passes through the threaded hole 12, and the abutment 21 and the handwheel 23 are respectively fixed at both ends of the screw 22. The abutment 21 is used to abut against the wall 7. The screw 22 utilizes the helical principle; a small-angle rotation of the handwheel 23 can be converted into a small, precise axial displacement of the screw 22, while simultaneously generating a large axial clamping force. This allows the fixing component 2 to very firmly abut the entire U-shaped frame 1 system against the walls 7, resisting vibration and load. Moreover, once tightened, it will not loosen unless the handwheel 23 is manually rotated in the opposite direction, and it is independent of any environmental conditions (such as temperature and humidity), providing a long-term, reliable fixing effect. In addition, this mechanical spiral clamping structure has low requirements for the wall surface. Whether the wall surface is flat, slightly uneven, coated or textured, as long as the abutment 21 can find a stress point, the mechanism can work and can be used on walls 7 of various materials, such as cement walls, brick walls, and wooden walls.

[0027] In some embodiments, the abutment 21 is a suction cup. In use, simply press the suction cup against a smooth wall surface to secure it; removal is as simple as pulling. This is ideal for temporary applications requiring frequent installation, removal, and repositioning. Furthermore, the suction cup operates using atmospheric pressure, eliminating the need for forceful pressing against the wall like mechanical clamps, thus preventing indentations, scratches, or drill holes and preserving the wall's integrity and aesthetics.

[0028] Fire hose fixing devices are in constant contact with water (even industrial wastewater and fire-fighting sewage containing acids and alkalis) and air, making them highly susceptible to corrosion and affecting their service life. Therefore, in some embodiments, both the connecting pipe 3 and the U-shaped frame 1 are made of stainless steel. Stainless steel pipes have excellent corrosion resistance, tensile strength, and yield strength, making them suitable for humid and harsh environments. They can withstand the impact of high-pressure water flow within the hose, the hose's own weight, and dragging force, preventing deformation and breakage that could lead to hose detachment. Furthermore, stainless steel pipes are widely adaptable and easy to process. They can be bent, welded, and machined into various structural forms such as the U-shaped frame 1 and connecting pipe 3 to meet the fixing requirements of different hose specifications. The processed structure is also lightweight, facilitating on-site installation and transportation while ensuring the stability of the fixing device.

[0029] Because there are tiny gaps at the connection surfaces of the hose and the fixing device, high-pressure water can easily leak from the connection. Therefore, in some embodiments, sealing rings 6 are respectively provided between the first connector 4 and the peripheral wall of the outlet 31, and between the second connector 5 and the peripheral wall of the inlet 32. The sealing rings 6 fill the gaps through compression deformation, forming a sealed cavity, which can effectively prevent high-pressure water from leaking from the connection, avoiding water waste or slippery ground and equipment damage caused by leakage. Furthermore, the hose will expand slightly during high-pressure water delivery, and the elasticity of the sealing rings 6 can adaptively adjust to the deformation of the hose, maintaining the sealing effect and preventing seal failure due to hose expansion.

[0030] Some uneven areas such as pits and gaps on the surface of the wall 7 can affect the friction between the U-shaped frame 1 and the wall 7, thus affecting the installation stability of the device. Therefore, in some embodiments, a plurality of spaced friction protrusions 13 are provided on the inner wall of the first side 14.

[0031] Please see Figure 2 The friction protrusions 13 increase the roughness of the contact surface, disrupting the sliding interface on the surface of the wall 7 and significantly improving the static friction coefficient. Even if the wall 7 is slightly tilted or vibrates, it can effectively resist the horizontal sliding force and prevent the overall displacement of the fixing device. For uneven parts such as pits and gaps on the surface of the wall 7, the friction protrusions 13 can be directly embedded into the recesses to form a "clamping" structure, restricting the displacement of the fixing device in the horizontal and vertical directions and solving the shaking problem caused by gaps when in planar contact.

[0032] It is worth noting that in this embodiment, the friction protrusions 13 are preferably made of stainless steel, and the friction protrusions 13 are integrally formed with the U-shaped frame 1, which ensures strength and avoids scratching the wall 7.

[0033] In some embodiments, the first connecting member 4 is a water valve, which has a switch and is screwed to the connecting pipe 3. The water valve can change the valve core opening by rotating the switch, achieving continuous flow regulation. It adjusts the water flow intensity according to the fire spread range, preventing the hose from rupturing due to excessive pressure from excessive flow, or failing to effectively extinguish the fire due to insufficient flow. Furthermore, the water valve can quickly close the outlet 31, stopping water supply without disassembling the hose, protecting the hose and connecting pipe 3, and extending their service life. When the hose is damaged or leaking, the water valve can quickly close the outlet 31, cutting off the water flow and preventing personnel injury or environmental damage caused by high-pressure water jets, thus improving operational safety.

[0034] In some embodiments, the second connector 5 is a quick-connect coupling, which is screwed onto the connecting pipe 3. The quick-connect coupling requires no tools and can be manually operated to connect to the hose, significantly improving connection and disassembly efficiency. It is particularly suitable for scenarios requiring rapid deployment, such as fire rescue and emergency water supply. Furthermore, the quick-connect coupling has wide adaptability, compatible with various hose specifications, eliminating the need for separate dedicated couplings for different hoses.

[0035] In some embodiments, the connecting pipe 3 and the U-shaped frame 1 are welded together. Welded connections provide a "permanent fixation," eliminating the loosening issues caused by vibration and thermal expansion and contraction of fasteners in mechanical connections. This ensures the long-term accuracy of the relative position of the connecting pipe 3 and the U-shaped frame 1, preventing overall failure of the fixing device due to loosening. Furthermore, after welding, the connecting pipe 3 and the U-shaped frame 1 form a single load-bearing unit, significantly improving their resistance to deformation. Even under strong impact, misalignment or deformation of the connection is less likely, ensuring the stability of the device.

[0036] In summary, the fire hose fixing device provided in this embodiment, in specific operation, firstly, the abutment surface 11 of the U-shaped frame 1 abuts against the wall 7 or windowsill. The fixing component 2 is adjusted according to the thickness of the windowsill or wall 7, so that the end of the fixing component 2 tightly abuts against the windowsill or wall 7, thereby fixing the device to the wall 7 or windowsill. Then, the two sections of hose are connected to the inlet 32 ​​and outlet 31 of the connecting pipe 3 respectively, and the hose and connecting pipe 3 are fixedly connected through the second connector 5 and the first connector 4, allowing water to be supplied for fire extinguishing. This device is simple to operate. By setting a connecting pipe 3 that conforms to the shape of the outer wall of the U-shaped frame 1 to transport fire-fighting water, it avoids direct hose transportation, prevents hose bending, and avoids friction caused by the hose contacting the wall 7 or windowsill, thus improving the service life of the hose. Furthermore, the overall structure of this device is simple, easy to carry and install, and has strong practicality.
