Description

Technical Field

[0001] This utility model relates to the field of fire protection equipment technology, specifically to an elastic telescopic emergency extension fire hose. Background Technology

[0002] Fire hoses are essential equipment commonly used in firefighting, generally consisting of an inner lining layer, a braided layer, and an outer covering layer. The inner lining layer is in direct contact with the water flow and requires excellent water resistance and sealing. The braided layer is typically made of high-strength fiber materials, providing strength and pressure resistance. The outer covering layer provides protection, preventing damage from the external environment. The inner lining layer commonly uses materials such as rubber, synthetic rubber, or plastic, offering wear resistance, corrosion resistance, and high-pressure resistance. The braided layer is made of materials such as polyester fiber and nylon, which possess high strength and flexibility, capable of withstanding the stretching and pressure during use. The outer covering layer typically uses a rubber or plastic coating to increase the hose's abrasion resistance and weather resistance.

[0003] When in use, fire hoses are connected to fire hydrants, fire trucks, or other water sources. Under pressure, water is transported from the source along the hose to the fire scene. When a firefighter turns on the nozzle, water is sprayed out from the nozzle under pressure, forming a jet or mist to extinguish the fire.

[0004] While existing fire hoses offer numerous advantages during use, they still suffer from several drawbacks. Firstly, their storage is inadequate. Because current fire hoses can only be placed on the ground for use, they are difficult to store later. Secondly, the dimensions of the fire hoses cannot be adjusted, affecting the smooth operation of the equipment. Utility Model Content

[0005] To address the problems in the existing technology, this utility model provides an elastic telescopic emergency extension fire hose.

[0006] The technical solution adopted by this utility model to solve its technical problem is an elastic telescopic emergency extension fire hose, including a storage compartment, a cover plate and a protective cover. A collection plate is rotatably installed inside the storage compartment. The cover plate is screwed to the upper outer wall of the storage compartment. A drive shaft is rotatably installed inside the cover plate. A fitting hole is opened inside the drive shaft. A protective cover is provided on the upper outer wall of the cover plate. A movable hole is opened inside the protective cover. A fitting post is provided inside the movable hole.

[0007] By adopting the above technical solution, the storage compartment can store the hose body, ensuring that the hose body is easy to store and transport, and avoiding the hose body from being messy and tangled. The rotating collection plate facilitates the winding and unfolding of the hose body, making operation convenient. The cover can cover the storage compartment and make it easy for staff to disassemble the storage compartment to maintain or replace the hose body inside. The locking column can restrict the drive shaft and ensure the controlled rotation of the drive shaft.

[0008] Specifically, protective pipes are inserted and installed on both outer walls of the storage compartment. A water hose body is installed inside the protective pipe. Water pipe connectors are installed on the outer walls of both ends of the water hose body. A through hole is opened inside the collection plate, and the water hose body is located inside the through hole. The upper end of the collection plate is embedded in the fitting hole, which adopts a through-hole design.

[0009] By adopting the above technical solutions, the protective pipe can protect the hose body when it is moved out or retracted into the storage compartment, avoiding wear on the surface of the hose body and ensuring its service life. The water pipe joint facilitates quick connection between the hose body and external equipment such as fire water sources and water guns, ensuring the efficiency of fire fighting operations. The through-hole design of the collection plate allows the hose body to pass through smoothly, and the collection plate can wrap and collect the hose body when it is not in use, so that the hose body can be stored in the storage compartment for protection. In addition, the upper part of the collection plate is embedded with the fitting hole of the drive shaft to realize power transmission and make the hose body retraction and extension smoother.

[0010] Specifically, the lower end of the inner wall of the storage compartment is provided with a circular array of drainage holes, and the lower outer wall of the storage compartment is provided with a circular array of bases.

[0011] By adopting the above technical solution, the drainage hole can effectively drain any water that may accumulate in the storage compartment, and the base provides stable support for the storage compartment, making it more stable when placed.

[0012] Specifically, one side of the drive shaft has a spring for providing torsional force, and the other end of the spring is connected to one side of the upper outer wall of the cover plate. The spring is located inside the protective cover.

[0013] By adopting the above technical solution, the reed provides torsional force to the drive shaft, enabling the collecting plate to rotate with the drive shaft. When the hose body is pulled out, the reed stores elastic potential energy. When it is necessary to rewind the hose body, the reed releases the elastic potential energy to drive the drive shaft to rotate in the opposite direction, realizing the automatic rewinding of the hose body. This saves manpower, makes the operation more convenient and efficient, and improves the work efficiency of firefighters in firefighting operations. The reed is located inside the protective cover and is effectively protected, not easily affected by external factors, ensuring its stable operation.

[0014] Specifically, the lower end of the outer wall of the protective cover is equipped with a circular array of connectors, and the protective cover is connected to the upper outer wall of the cover plate by screws through the connectors.

[0015] By adopting the above technical solution, the connector ensures the stability of the protective cover's position on the upper surface of the cover plate, and facilitates the subsequent disassembly of the protective cover, making it easier for staff to maintain the spring.

[0016] Specifically, both the outer wall of the fitting post and the inner wall of the fitting hole are designed in a rectangular shape, and the fitting post is located inside the fitting hole.

[0017] By adopting the above technical solution, when the inserting column is inserted into the inserting hole through the movable hole, the inserting column can achieve the purpose of restricting the drive shaft and ensuring that the drive shaft rotates in a controlled manner. When it is necessary to release the water hose body, the staff disassembles the inserting column and pulls the two ends of the water hose body to move them respectively, so that the water hose body wrapped around the outside of the collection plate can be released simultaneously through the protective pipes on both sides. After that, the staff puts the inserting column into the inserting hole to restrict the drive shaft again and ensure that the collection plate controls the winding of the water hose body.

[0018] Specifically, the upper outer wall of the protective cover is equipped with a rectangular array of buckles, and the upper outer wall of the fitting column is equipped with a locking block, which is engaged and installed inside the buckles.

[0019] By adopting the above technical solution, the buckle and the locking block can fix the interlocking column on the protective cover, preventing it from shaking or falling off at will when not in operation. When it is necessary to operate the hose body to retract or extend, the connection between the locking block and the buckle can be easily opened.

[0020] The beneficial effects of this utility model are:

[0021] (1) The elastic telescopic emergency extension fire hose described in this utility model can store the hose body, ensuring that the hose body is easy to store and transport, avoiding the hose body from being messy and tangled.

[0030] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0031] To save manpower and improve efficiency, as one embodiment of this utility model, such as Figure 1 , Figure 2 , Figure 3 , Figure 4 , Figure 5 As shown, the elastic telescopic emergency extension fire hose of this utility model includes a storage compartment 1, a cover plate 2, and a protective cover 3. A collection plate 16 is rotatably installed inside the storage compartment 1. The cover plate 2 is screwed to the upper outer wall of the storage compartment 1. A drive shaft 21 is rotatably installed inside the cover plate 2. A fitting hole 22 is opened inside the drive shaft 21. The protective cover 3 is provided on the upper outer wall of the cover plate 2. A movable hole 32 is opened inside the protective cover 3. A fitting post 35 is provided inside the movable hole 32.

[0032] In use, the storage compartment 1 can store the hose body 13, ensuring that the hose body 13 is easy to store and transport, and preventing the hose body 13 from being messy and tangled. The rotating collection plate 16 facilitates the winding and unfolding of the hose body 13, making operation convenient. The cover plate 2 can cover the storage compartment 1 and facilitate the staff to disassemble the storage compartment 1 to maintain or replace the hose body 13 inside. The locking column 35 can restrict the drive shaft 21 to ensure the controlled rotation of the drive shaft 21.

[0033] For example, to rewind, such as Figure 2As shown, protective pipes 12 are inserted and installed on both outer walls of the storage compartment 1. A water hose body 13 is installed inside the protective pipe 12. Water pipe connectors 14 are installed on the outer walls of both ends of the water hose body 13. A through hole is opened inside the collection plate 16, and the water hose body 13 is located inside the through hole. The upper end of the collection plate 16 is embedded in the fitting hole 22. The fitting hole 22 adopts a through-hole design.

[0034] During use, the protective tube 12 protects the hose body 13 when it is moved out or retracted into the storage compartment 1, preventing wear on the surface of the hose body 13 and ensuring its service life. The water pipe connector 14 facilitates quick connection of the hose body 13 to external equipment such as fire water sources and water guns, ensuring the efficiency of fire extinguishing operations. The through-hole design of the collection plate 16 allows the hose body 13 to pass through smoothly, and the collection plate 16 can wind and collect the hose body 13 when it is not in use, so that the hose body 13 can be stored in the storage compartment 1 for protection. The upper end of the collection plate 16 is embedded in the fitting hole 22 of the drive shaft 21 to realize power transmission, making the hose body 13 easier to extend and retract, thereby extending the overall length of the hose body 13.

[0035] To maintain the usage location, for example, such as Figure 2 As shown, the lower end of the inner wall of the storage compartment 1 is provided with a circular array of drainage holes 15 for drainage, and the lower outer wall of the storage compartment 1 is provided with a circular array of bases 11.

[0036] When in use, the drain hole 15 can effectively drain any water that may accumulate in the storage compartment 1, and the base 11 provides stable support for the storage compartment 1, making it more stable when placed.

[0037] For the purpose of extending the hose body 13, exemplarily, such as... Figure 3 As shown, there is a spring 23 on one side of the outer wall of the drive shaft 21 for providing torsional force. The other end of the spring 23 is connected to one side of the upper outer wall of the cover plate 2. The spring 23 is located inside the protective cover 3.

[0038] In use, the spring 23 provides torsional force to the drive shaft 21, enabling the collecting plate 16 to rotate with the drive shaft 21. When the hose body 13 is pulled out, the spring 23 stores elastic potential energy. When it is necessary to rewind the hose body 13, the spring 23 releases the elastic potential energy to drive the drive shaft 21 to rotate in the opposite direction, realizing the automatic rewinding of the hose body 13, saving manpower, making operation more convenient and efficient, and improving the work efficiency of firefighters in firefighting operations. The spring 23 is located inside the protective cover 3 and is effectively protected, not easily affected by external factors, ensuring its stable operation. Thus, the elasticity of the spring 23 enables the controlled extension and retraction of the hose body 13. The spring 23 adopts a spiral spring. When the collecting plate 16 rotates counterclockwise, it rewinds the hose body 13, and at this time the spring 23 stores elastic potential energy. When rotating in the opposite direction, the spring 23 releases energy, which can drive the drive shaft 21 to reset.

[0039] To maintain the usage location, for example, such as Figure 4 As shown, a circular array of connectors 31 are installed on the lower end of the outer wall of the protective cover 3, and the protective cover 3 is connected to the upper outer wall of the cover plate 2 by screws through the connectors 31.

[0040] During use, the connector 31 ensures the stability of the protective cover 3 on the upper surface of the cover plate 2, and facilitates the subsequent disassembly of the protective cover 3, making it easier for staff to maintain the spring 23.

[0041] For controlled rotation, exemplified, such as Figure 5 As shown, the outer wall of the fitting post 35 and the inner wall of the fitting hole 22 are both designed in a rectangular shape, and the fitting post 35 is located inside the fitting hole 22.

[0042] In use, when the fitting post 35 is inserted into the fitting hole 22 through the movable hole 32, the fitting post 35 can restrict the drive shaft 21 and ensure that the drive shaft 21 rotates in a controlled manner. When it is necessary to release the hose body 13, the staff disassembles the fitting post 35 and pulls the two ends of the hose body 13 to move them, so that the hose body 13 wrapped around the outside of the collection plate 16 can be released synchronously through the protective tubes 12 on both sides. After that, the staff puts the fitting post 35 into the fitting hole 22 to restrict the drive shaft 21 again, ensuring that the collection plate 16 can control the winding of the hose body 13.

[0043] To fix the usage location, for example, such as Figure 4 As shown, the upper outer wall of the protective cover 3 is equipped with a rectangular array of buckles 33, and the upper outer wall of the fitting column 35 is equipped with a locking block 34, which is snapped into the inside of the buckle 33.

[0044] When in use, the buckle 33 and the locking block 34 can fix the locking post 35 on the protective cover 3 to prevent it from shaking or falling off when not in operation. When it is necessary to operate the hose body 13 to retract or extend, the connection between the locking block 34 and the buckle 33 can be easily opened.

[0045] When using this utility model, the operator opens the connection between the upper outer wall latch 34 of the fitting column 35 and the buckle 33 on the protective cover 3, and pulls the fitting column 35 out of the fitting hole 22. At this time, the drive shaft 21 is no longer restricted by the fitting column 35. The operator pulls both ends of the water hose body 13 respectively. Due to the through hole design of the collection plate 16, the water hose body 13 is in a state of being rolled up outside the collection plate 16 when it is not unfolded. When the water hose body 13 is pulled, both ends of the water hose body 13 are moved out of the protective tube 12 respectively. When the water hose body 13 is moved out, the collection plate 16 will be driven to rotate, thereby storing energy in the spring plate 23 through the drive shaft 21.

[0046] After the hose body 13 is stretched to the required length, the workers first insert the fitting post 35 back into the fitting hole 22 to restrict the state of the collecting plate 16. Then, the workers can connect the water pipe joint 14 on the outside of the hose body 13 to the fire water source, so that the fire water source can be transported through the hose body 13.

[0047] After the firefighting operation is completed, the workers remove the interlocking post 35 from the protective cover 3 and disconnect the hose body 13 from the fire water source. Since the spring 23 stored elastic potential energy when the hose body 13 was pulled out, the spring 23 releases the elastic potential energy to drive the drive shaft 21 to rotate in the opposite direction, which in turn drives the collecting plate 16 to rotate, and begins to automatically rewind the hose body 13. During the rewinding process, the hose body 13 retracts into the storage compartment 1 through the protective tube 12.

[0048] After the hose body 13 is completely rolled into the storage compartment 1, the staff will re-engage the locking block 34 into the buckle 33 to fix the locking post 35, prevent the drive shaft 21 from rotating randomly, and ensure that the hose body 13 is stably stored in the storage compartment 1.
