Description

Technical Field

[0001] This utility model relates to the field of water gun technology, specifically a multifunctional telescopic water gun for confined spaces. Background Technology

[0002] Water nozzles, as core equipment for fluid spraying, are widely used in diverse scenarios such as fire rescue, garden irrigation, and industrial sprinkler systems. However, with the increasing complexity of modern building structures and the diversification of fire scenarios and working environments, the fire protection needs of confined spaces such as building mezzanines, car chassis, and ship engine rooms, as well as special working conditions such as cleaning the gaps in precision equipment and maintaining vertical greenery, all pose higher challenges to the applicability of water nozzles.

[0003] Most mainstream water guns on the market today adopt a fixed structure integrating the gun body and nozzle, or only support limited angle adjustment. In fire fighting and rescue operations, precision irrigation, and equipment spraying in confined spaces, these water guns are limited by space constraints, making it difficult to reach critical areas and accurately deliver water to the target location, resulting in a significant reduction in operational efficiency and even missing the best opportunity for response. Even if some products have a telescopic function, problems such as sealing failure and leakage are prone to occur after extension, causing a decrease in spray pressure and seriously affecting the actual effectiveness of fire fighting and control, irrigation penetration, and equipment cleaning. Utility Model Content

[0004] In view of the shortcomings of the existing technology, this utility model provides a multi-functional telescopic water gun for confined spaces.

[0005] To achieve the above objectives, the technical solution of this utility model is as follows:

[0006] Multi-functional telescopic water gun for confined spaces, including a main pipe with a valve;

[0007] Sprayer components;

[0008] The telescopic mechanism includes several coaxial sliding nested sleeves, the outermost sleeve is connected to the main valve pipe, and the innermost sleeve is connected to the spray element.

[0009] Each sleeve includes:

[0010] The first rubber ring is located on the inner wall of the sleeve near the end of the spraying component. Its inner wall is provided with several equidistant first annular elastic protrusions, and a first sealing gap is formed between each two adjacent first annular elastic protrusions.

[0011] The second rubber ring is located on the outer wall of the sleeve near the end of the main valve tube. Its outer wall is provided with several equally spaced second annular elastic protrusions, and a second sealing gap is formed between each two adjacent second annular elastic protrusions.

[0012] When the telescopic mechanism extends, the adjacent nested sleeves are connected end to end, and the second rubber ring of the inner sleeve slides into the first rubber ring of the outer sleeve. The first annular elastic protrusion and the second annular elastic protrusion alternately engage to form a sealing structure.

[0013] Preferably, the thickness of the first rubber ring increases in the direction toward the spray element, so that the plurality of first annular elastic protrusions on its inner wall are distributed in a progressive step-like manner, and the thickness of the second rubber ring decreases in the direction toward the spray element, so that the plurality of second annular elastic protrusions on its inner wall are distributed in a decreasing step-like manner.

[0014] Preferably, the widths of the first annular elastic protrusion and the second annular elastic protrusion are the same, and the widths of the first sealing gap and the second sealing gap are the same and the same as the widths of the first annular elastic protrusion and the second annular elastic protrusion.

[0015] Preferably, each of the sleeves is provided with an annular expansion plate at the end near the valve main pipe, and the annular expansion plate is provided with an inwardly concave arc surface to increase the contact area with the water flow.

[0016] Preferably, the spray component includes a connecting pipe, a universal joint and a detachable nozzle connected in sequence, and the connecting pipe is connected to the innermost sleeve of the telescopic mechanism.

[0017] Preferably, one end of the valved main pipe is provided with an interface for connecting a water hose.

[0018] Compared with the prior art, the beneficial effects of this utility model are as follows: by replacing the detachable nozzle, multiple spray modes such as high-pressure direct spray, fan-shaped spray, and atomization can be realized, which is suitable for various scenarios such as fire extinguishing, flushing, and watering; and the telescopic mechanism can flexibly switch the storage and extension states of the device. When stored, the structure is compact and easy to carry, and when extended, it can work in confined spaces; the adjacent sleeves are interlocked by the annular elastic protrusions of the first and second rubber rings, which effectively solves the problem of water leakage after extension and extension and ensures the spray pressure; and the concave arc surface of the annular extension plate uses the water flow thrust to help it extend automatically, which greatly improves the convenience of use.

[0027] Example

[0028] like Figures 1-5 As shown, the multi-functional telescopic water gun for confined spaces includes a main pipe 1 with a valve, which serves as the main water supply channel for the entire device. One end of the main pipe is connected to a water hose via an interface 4 to provide a water source for the system. The built-in valve can control the flow of water and regulate the flow rate.

[0029] Sprayer component 2; Sprayer component 2 includes a connecting pipe 21, a universal joint 22 and a detachable nozzle 23 connected in sequence, and the connecting pipe 21 is connected to the innermost sleeve 31 of the telescopic mechanism 3; wherein, the universal joint 22 allows the detachable nozzle 23 to rotate flexibly within a multi-angle range to adjust the spray direction; the detachable nozzle 23 can achieve multiple spray modes by replacing different nozzle structures, thus expanding the applicability of the device (such as fire extinguishing, flushing, watering, etc.).

[0030] Among them, high-pressure direct-fire nozzles can provide concentrated, high-intensity water flow, which can powerfully wash away stubborn stains (such as machine oil stains) or extinguish fires in a fan-shaped, targeted manner (penetrating the core area of ​​the flame); fan-shaped spray nozzles can form a large area of ​​water flow coverage, which is suitable for large-area ground washing, dust suppression (such as construction sites and warehouses), and plant irrigation (uniform watering); atomizing nozzles can transform water flow into fine water mist, which is suitable for cooling the fire scene (lowering the ambient temperature and inhibiting the spread of fire) and humidifying the air.

[0031] The telescopic mechanism 3 includes several coaxially sliding nested sleeves 31. The outermost sleeve 31 is connected to the valve main pipe 1, and the innermost sleeve 31 is connected to the spray component 2, so as to realize the flexible switching of "storage-extension".

[0032] Each sleeve 31 includes:

[0033] The first rubber ring 310 is located on the inner wall of the sleeve 31 near the end of the spray member 2. Its inner wall is provided with a number of first annular elastic protrusions 311 arranged at equal intervals, and a first sealing gap is formed between each two adjacent first annular elastic protrusions 311.

[0034] The second rubber ring 312 is located on the outer wall of the sleeve 31 near the end of the valve main pipe 1. Its outer wall is provided with several equally spaced second annular elastic protrusions 313, and a second sealing gap is formed between each two adjacent second annular elastic protrusions 313.

[0035] The thickness of the first rubber ring 310 increases towards the spray element 2, so that the multiple first annular elastic protrusions 311 on its inner wall are distributed in a progressive step-like manner. The thickness of the second rubber ring 312 decreases towards the spray element 2, so that the multiple second annular elastic protrusions 313 on its inner wall are distributed in a decreasing step-like manner. The stepped interlocking design of the first annular elastic protrusions 311 and the second annular elastic protrusions 313 ensures the smoothness of the expansion and contraction of the sleeve 31 and significantly improves the sealing reliability under high-pressure water flow (the contact surfaces of the two form a tight sealing effect under the action of high-pressure water flow). This design effectively solves the problems of leakage and wear of traditional sealing structures under high pressure and high frequency use, while taking into account both structural compactness (nested sleeve 31) and functional integrity (long-distance water transportation).

[0036] The widths of the first annular elastic protrusion 311 and the second annular elastic protrusion 313 are the same, and the widths of the first sealing gap and the second sealing gap are the same and the same as the widths of the first annular elastic protrusion 311 and the second annular elastic protrusion 313. When the sleeves 31 are connected end to end, the first annular elastic protrusion 311 is inserted into the first sealing gap, and the second annular elastic protrusion 313 is inserted into the second sealing gap.

[0037] In addition, each sleeve 31 is provided with an annular expansion plate 314 at the end near the valve main pipe 1, and the annular expansion plate 314 is provided with an inward concave arc surface 315 to increase the contact area with the water flow; when the water flow impacts the inward concave arc surface 315, it can increase the thrust of the water flow on the sleeve 31, help the telescopic mechanism 3 to extend automatically, and improve the convenience of use.

[0038] When the telescopic mechanism 3 extends, the adjacent nested sleeves 31 are connected end to end, and the second rubber ring 312 of the inner sleeve 31 slides into the first rubber ring 310 of the outer sleeve 31. The first annular elastic protrusion 311 and the second annular elastic protrusion 313 alternately engage. Through the alternating engagement design, the smooth sliding of the sleeve 31 is ensured, and the waterproof effect is enhanced by the multi-layer elastic seal, ensuring the sealing performance under high pressure water flow.

[0039] In summary, sleeve 31 has a retracted state and an extended state:

[0040] Storage configuration: The sleeve 31 is coaxially nested, with a compact structure, small footprint, and easy to carry (e.g., when paired with a water hose, it can be easily stored in a toolbox, vehicle trunk, etc.).

[0041] Extended state: The sleeve 31 is connected end to end to form a long strip channel, which can reach into narrow spaces (such as inside pipes, machine gaps, high-altitude interlayers, vehicle chassis, etc.) to solve fire or cleaning needs in areas that are difficult to reach by traditional fire extinguishing / washing equipment.

[0042] The technical scope of this utility model is not limited to the content described above. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the protection scope of this utility model.
