Description

Technical Field

[0001] This utility model relates to the field of fire hoses, and in particular to a tensile-resistant lined fire hose. Background Technology

[0002] Fire hoses are essential firefighting equipment widely used in buildings, factories, ships, and infrastructure, primarily for transporting fire-fighting water or other extinguishing agents. With societal progress and rising fire safety standards, the requirements for fire hoses are becoming increasingly stringent.

[0003] There is currently a Chinese patent document CN202223070423.X describing a high-pressure resistant, lined fire hose made of polyester filament polyurethane. The fire hose includes a hose body and a connector. The connector is fixed to the right side of the hose body. A high-pressure resistant device is installed inside the hose body, and a clamping device is installed on the outer right side wall of the hose body. Polyester filament polyurethane can be used as the fire hose body. A protective layer and an inner lining layer are then processed inside the hose body. A flow guide groove is processed on the inner wall of the inner lining layer to guide the water flow and reduce the pressure to some extent. An anti-corrosion layer is then processed on the inner wall of the inner lining layer, resulting in good corrosion resistance. Thus, the protective layer, inner lining layer, and anti-corrosion layer can improve the fire hose's performance. The high pressure resistance and wear resistance of the fire hose body reduce its workload, thereby extending the service life of the fire hose body.

[0004] However, the above-mentioned patent has certain defects in use. In actual use, fire hoses often need to be dragged, bent and even subjected to great tensile force in complex environments. If the design of the protective layer, inner lining layer and anti-corrosion layer is damaged, the entire hose needs to be replaced, resulting in high overall maintenance costs.

[0005] Therefore, a tensile-resistant lined fire hose is proposed here to solve the aforementioned problems. Utility Model Content

[0006] In order to overcome the shortcomings of existing technologies where the entire hose needs to be replaced when damaged, resulting in high overall maintenance costs, this utility model provides a tensile-resistant lined fire hose.

[0007] This utility model is achieved using the following technical solution: A tensile-resistant lined fire hose includes a hose body and a connector. The connector is provided with a connecting disc at its end. The hose body is provided with end caps at both ends. The end caps are provided with mounting heads. The connector has a built-in sleeve. The mounting head and the sleeve are plugged in. The inner peripheral wall of the mounting head is provided with at least one slot. The outer peripheral wall of the sleeve is provided with a plug that matches the slot. The wear-resistant outer belt is wrapped around the outer peripheral wall of the hose body. The wear-resistant outer belt has quick-release heads at both ends, which are bolted to the end caps. The outer peripheral wall of the hose body has Velcro fasteners, and the inner peripheral wall of the wear-resistant outer belt has Velcro female fasteners. The Velcro fasteners and Velcro female fasteners are bonded together.

[0008] In a preferred embodiment of this utility model, a plurality of positioning holes are provided through the connecting disc and the end cap. A fastening device is provided on the outer wall of the end cap. The fastening device includes a hinge seat and a clamping seat. The hinge seat is fixed to the outer wall of the end cap, and the hinge seat and the clamping seat are hinged together. A pressure rod is movably connected to one end of the clamping seat, and the pressure rod matches the positioning holes. As a preferred embodiment of this utility model, the insert has a built-in flow-through sleeve, which is connected to the main body of the water hose, and the radial dimension of the inner ring of the flow-through sleeve is consistent with the inner diameter of the main body of the water hose.

[0009] As a preferred embodiment of this utility model, the inner wall of the water hose body is provided with an anti-corrosion layer.

[0010] As a preferred embodiment of this utility model, multiple buckles are evenly arranged on the peripheral wall of the wear-resistant outer belt.

[0011] In a preferred embodiment of this utility model, the number of positioning holes is the same as the number of fastening devices, and a knob is provided at the end of the pressure rod.

[0012] In a preferred embodiment of this utility model, the length of the water hose body is the same as that of the wear-resistant outer belt.

[0013] Compared with existing technologies, the advantages of this utility model are: 1. By setting Velcro buckles on the outer wall of the water hose body, the Velcro female buckles on the inner wall of the wear-resistant outer belt are glued together. At the same time, the two ends of the wear-resistant outer belt are connected to the end cap bolts through quick-release heads, so that the wear-resistant outer belt is firmly installed and easy to disassemble. This makes it easy to replace the severely worn parts individually, thereby extending the service life of the entire water hose.

[0014] 2. The end cap is fixed to the connector by a fastening device on the outer wall, which is convenient and quick. After the installation head is inserted into the sleeve, the clamp is rotated until the pressure rod is aligned with the positioning hole after the pre-installation is completed. The knob is turned to insert the pressure rod into the positioning hole. The operation is simple.

[0015] 3. The design of the slots and plugs makes installation more convenient. During installation, simply align the plug with the slot and insert it to complete the initial fixation. During use, installation can be completed quickly. Attached Figure Description

[0021] Specifically, a plurality of positioning holes 35 are provided through the connecting plate 23 and the end cover 11. A fastening device 3 is provided on the outer wall of the end cover 11. The fastening device 3 includes a hinge 31 and a clamp 32. The hinge 31 is fixed to the outer wall of the end cover 11. The hinge 31 and the clamp 32 are hinged together. One end of the clamp 32 is movably connected to a pressure rod 33, and the pressure rod 33 matches the positioning holes 35.

[0022] In this embodiment, a plurality of positioning holes 35 are provided through the connecting plate 23 and the end cap 11. When the connector 2 is pre-installed, the connecting plate 23 and the end cap 11 are fitted together, and the plurality of positioning holes 35 on the connecting plate 23 and the end cap 11 correspond one-to-one. The number of positioning holes 35 is the same as the number of fastening devices 3. After the mounting head 12 is inserted into the insert 21, it is fixed by the fastening device 3. The fastening device 3 includes a hinge seat 31 and a clamp seat 32. The hinge seat 31 is fixed on the outer side wall of the end cap 11, and the clamp seat 32 is fixed to the hinge seat 32. 1. A hinge is formed. The clamp 32 has a C-shaped structure. A pressure rod 33 is movably provided at one end of the clamp 32. The pressure rod 33 can rotate around the end of the clamp 32. A knob 34 is provided at the end of the pressure rod 33. The connecting plate 23 and the end cover 11 are provided with multiple positioning holes 35. When fixing, the clamp 32 is rotated until the pressure rod 33 is aligned with the positioning hole 35. The knob 34 is turned to insert the pressure rod 33 into the positioning hole 35, thereby realizing the quick fixing and disassembly of the mounting head 12 and the connector 2, improving the ease of use.

[0023] Specifically, the insert 21 has a built-in flow-following sleeve 24, which is connected to the water hose body 1, and the radial dimension of the inner circle of the flow-following sleeve 24 is consistent with the inner diameter of the water hose body 1.

[0024] In this embodiment, the insert 21 contains a flow-following sleeve 24, which is connected to the hose body 1. The radial dimension of the inner ring of the flow-following sleeve 24 is the same as the inner diameter of the hose body 1. When the insert 21 in the connector 2 is inserted into the mounting head 12, the flow-following sleeve 24 is inserted into the mounting head 12 and fits against the inner wall of the hose body 1. The flow-following sleeve has a conical structure with a smooth outer wall that is consistent with the direction of water flow, reducing the resistance when water flows through and improving the smoothness of water flow.

[0025] Specifically, the inner wall of the water hose body 1 is provided with an anti-corrosion layer 5.

[0026] In this embodiment, an anti-corrosion layer 5 is formed on the inner wall of the water hose body 1 to prevent corrosion caused by long-term contact with the water hose body 1. The outermost layer of the entire water hose is an anti-wear outer belt 4, the middle part is the water hose body 1, and the inner layer is the anti-corrosion layer 5, forming a three-dimensional tensile structure.

[0027] Specifically, multiple latches 43 are evenly arranged on the four sides of the wear-resistant outer belt.

[0028] In this embodiment, multiple buckles 43 are evenly arranged on the periphery of the wear-resistant outer belt 4. The buckles 43 are locking clamps. The quick-release heads 41 at both ends of the wear-resistant outer belt 4 are bolted and installed stably. However, the wear-resistant outer belt 4 in the middle is only fixed by Velcro and is prone to loosening after long-term use. In order to enhance the fixing effect of the wear-resistant outer belt 4, multiple buckles 43 are evenly arranged on the periphery of the wear-resistant outer belt 4. The wear-resistant outer belt 4 is tightly fixed to the water hose body 1 by the buckles 43, preventing the wear-resistant outer belt 4 from loosening or falling off during use, and further improving the overall structural stability and service life of the water hose.

[0029] The principle of this utility model is as follows: the outermost layer of the entire water hose is an anti-wear outer belt 4, the middle part is the water hose body 1, and the inner layer is an anti-corrosion layer 5, forming a three-dimensional tensile structure. During use, the water hose needs to be dragged and bent frequently. The anti-wear outer belt 4 is the outermost contact wear surface, which effectively reduces the direct friction between the water hose body 1 and the external environment. The anti-wear outer belt 4 wraps around the outer periphery of the water hose body 1. The quick-release heads 41 at both ends of the anti-wear outer belt 4 are fixed to the end caps 11 by bolts, which facilitates installation and disassembly. This makes the anti-wear outer belt 4 firmly installed and easy to disassemble, and it is convenient to replace the severely worn parts individually, thereby extending the service life of the entire water hose.

[0030] When installing connector 2, insert block 22 is aligned with slot 13 and inserted along the trajectory of slot 13. When insert block 22 reaches the end of slot 13, rotate connector 2 so that insert block 22 is locked in the L-shaped horizontal groove of slot 13. At this time, connector 2 is pre-installed and connector 2 is attached to end cover 11. At this time, connector 23 corresponds one-to-one with multiple positioning holes 35 on end cover 11. Rotate clamp 32 until the pressure rod 33 is aligned with the positioning hole 35. Rotate knob 34 to insert pressure rod 33 into positioning hole 35, thereby realizing quick fixing and disassembly of mounting head 12 and connector 2, improving ease of use.

[0031] 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 its improved concept should be covered within the protection scope of the present utility model.
