Description

Technical Field

[0001] This utility model relates to the field of high-pressure fine water mist gun technology, and more specifically, it relates to a telescopic high-pressure fine water mist gun. Background Technology

[0002] Fine water mist fire extinguishers have excellent spray performance, using high-pressure technology to break down water into micron-sized atomized particles. These highly diffusive water mists can quickly form a comprehensive protective water curtain, effectively reducing temperature and controlling fire.

[0003] Patent document CN220801782U discloses a telescopic high-pressure fine water mist gun, including a handle. A threaded cylinder is movably mounted on one side of the handle, and a protective shell is fixedly mounted on one side of the threaded cylinder. A transmission assembly is disposed inside the protective shell, and multiple lead screws are mounted on one side of the transmission assembly and inside the protective shell. The lead screws are rotatably connected to the inner wall of the protective shell, and a positioning nut is threaded to the outer end of the lead screws. The beneficial effects of this utility model are: through the cooperation between the nozzle and the adjusting hose, the nozzle can be housed inside the protective shell. The sealed protection of the nozzle not only prevents damage to the nozzle from unexpected external forces but also prevents dust from clogging the nozzle orifice, extending the nozzle's service life. The cooperation between the threaded rod and the clamping plate facilitates the disassembly of the handle and the protective shell, eliminating the need for numerous parts and improving the practicality of the fine water mist gun.

[0004] However, during use, when a fire occurs and the nozzle needs to be removed, the lever needs to be rotated multiple times before the nozzle can be moved. This removal method is cumbersome and time-consuming. In the fast-paced fire rescue scene, such delays may affect the efficiency of initial fire suppression and thus miss the best opportunity to extinguish the fire. Secondly, during use, the movable cover is opened by the nozzle. After prolonged use, the nozzle is prone to wear and tear, which reduces its lifespan and increases maintenance costs.

[0031] Please see Figures 1-6 A telescopic high-pressure fine water mist gun includes a handle 1, a connecting pipe 2 on the handle 1, a protective shell 3 fixedly mounted on the connecting pipe 2, a flexible hose 4 fixedly mounted at one end of the connecting pipe 2 inside the protective shell 3, a nozzle 5 fixedly mounted at one end of the flexible hose 4, a movable fixing frame 6 on the protective shell 3, the lower end of the fixing frame 6 extending into the protective shell 3 and fixedly connected to the nozzle 5, a lifting plate 7 movably mounted inside the fixing frame 6, two fixing blocks 8 fixedly mounted on the lifting plate 7, and four fixing grooves 9 inside the protective shell 3 that mate with the fixing blocks 8. A spring 10 is fixedly connected between the plate 7 and the fixed frame 6. A pressing rod 11 is fixedly provided at the upper end of the lifting plate 7, and the upper end of the pressing rod 11 extends to the outside of the fixed frame 6. A moving groove 12 that cooperates with the fixed frame 6 is provided on the protective shell 3. A moving seat 13 is fixedly provided at the lower end of the nozzle 5. The moving seat 13 and the protective shell 3 are slidably connected through a track structure. A dustproof frame 21 is fixedly provided on the fixed frame 6. Two connecting plates 22 are fixedly provided on the protective shell 3. Bellows covers 23 are fixedly provided on both sides of the dustproof frame 21 and between the two connecting plates 22.

[0032] In this embodiment, when it is necessary to remove the nozzle 5, press the pressing rod 11. The pressing rod 11 drives the lifting plate 7 to move downward, the spring 10 is compressed, and the lifting plate 7 drives the two fixing blocks 8 to move out of the fixing groove 9. At this time, the limit on the nozzle 5 is released. Push the pressing rod 11 so that the pressing rod 11 drives the fixing frame 6 to move in the moving groove 12. The fixing frame 6 drives the nozzle 5 to move. The nozzle 5 drives the moving seat 13 to move along the sliding connection with the protective shell 3. When the fixing frame 6 moves to one end of the moving groove 12, the two fixing blocks 8 are aligned with the other two fixing grooves 9. Release the pressing rod 11. Under the push of the spring 10, the lifting plate 7 drives the fixing blocks 8 to move and insert the two fixing blocks 8 into the two fixing grooves 9, thus fixing the nozzle 5. At this time, one end of the nozzle 5 extends out of the protective shell 3. Water enters the connecting pipe 2 through the handle 1 and then sprays out from the nozzle 5 through the hose 4. Since the handle 1 is existing technology, its internal structure and working principle will not be described in detail here. After the nozzle 5 is used up, the reverse operation can be used to move the nozzle 5 and fix it inside the protective shell 3. When the fixing frame 6 moves, it will drive the dustproof frame 21 to move, so that the bellows covers 23 on both sides of the dustproof frame 21 can extend and retract to cover the moving groove 12 to prevent dust.

[0033] Please see Figures 1-6 As one embodiment for opening the movable cover: a push rod 14 is fixedly provided on one side of the fixed frame 6 and the movable seat 13 respectively. A mounting seat 15 is threaded on one end of the push rod 14. A ball bearing 16 is rotatably provided on one end of the mounting seat 15. A support plate 17 is provided on one side of the protective shell 3. There are four support plates 17. A limiting shaft 18 is fixed between two corresponding support plates 17. A movable cover 19 is rotatably provided on the limiting shaft 18. A torsion spring 20 is movably provided on the outside of the limiting shaft 18. The two ends of the torsion spring 20 abut against the protective shell 3 and the movable cover 19 respectively.

[0034] More specifically, during the removal of the nozzle 5, the fixed frame 6 and the movable seat 13 move simultaneously, driving the two push rods 14 to move. The push rods 14 drive the mounting seat 15 to move, and the mounting seat 15 drives the ball bearing 16 to move. Since the ball bearing 16 is closer to the movable cover 19 than the nozzle 5, it comes into contact with the movable cover 19. The ball bearing 16 rotates and pushes the movable cover 19, causing the movable cover 19 to rotate around the point of rotational connection with the limiting shaft 18. The torsion spring 20 deforms. During the retraction of the nozzle 5, it drives the push rods 14 and the ball bearing 16 back. The movable cover 19 loses its pushing force, and under the action of the torsion spring 20, the movable cover 19 blocks one end of the protective shell 3, thus preventing dust. When the ball bearing 16 is damaged and needs to be replaced, rotate the mounting seat 15 to separate it from the push rod 14, and the ball bearing 16 can be removed. The replaced mounting seat 15 and ball bearing 16 can be installed by reversing the operation.

[0035] In summary, during the use or operation of the entire equipment: when it is necessary to remove the nozzle 5, press the pressing rod 11. The pressing rod 11 moves the lifting plate 7 downward, compressing the spring 10. The lifting plate 7 moves the two fixing blocks 8 out of the fixing groove 9, releasing the limit on the nozzle 5. Push the pressing rod 11, causing the pressing rod 11 to move the fixing frame 6 within the moving groove 12. The fixing frame 6 moves the nozzle 5, and the nozzle 5 moves the moving seat 13 along the sliding connection with the protective shell 3. When the fixing frame 6 moves... When the nozzle reaches one end of the moving slot 12, the two fixing blocks 8 are aligned with the other two fixing slots 9. Releasing the pressing rod 11, the spring 10 pushes the lifting plate 7 to move the fixing blocks 8, inserting them into the two fixing slots 9, thus fixing the nozzle 5. At this point, one end of the nozzle 5 extends from the protective shell 3. Water enters the connecting pipe 2 via the handle 1 and then sprays out from the nozzle 5 through the hose 4. Since the handle 1 is existing technology, its internal structure and working principle will not be described here. After use, the nozzle 5 can be moved and fixed back into the protective shell 3 using the reverse operation. Simultaneously, the moving frame 6 moves the dustproof frame 21, causing the bellows covers 23 on both sides of the dustproof frame 21 to extend and retract, shielding the moving slot 12 from dust.

[0036] During the removal of the nozzle 5, the fixed frame 6 and the movable seat 13 move simultaneously, driving the two push rods 14 to move. The push rods 14 drive the mounting seat 15 to move, and the mounting seat 15 drives the ball bearing 16 to move. Since the ball bearing 16 is closer to the movable cover 19 than the nozzle 5, it comes into contact with the movable cover 19. The ball bearing 16 rotates and pushes the movable cover 19, causing the movable cover 19 to rotate around the point of rotational connection with the limiting shaft 18. The torsion spring 20 deforms. During the retraction of the nozzle 5, it drives the push rods 14 and the ball bearing 16 back. The movable cover 19 loses its pushing force, and under the action of the torsion spring 20, the movable cover 19 blocks one end of the protective shell 3, thus preventing dust. When the ball bearing 16 is damaged and needs to be replaced, rotate the mounting seat 15 to separate it from the push rod 14, and the ball bearing 16 can be removed. The replaced mounting seat 15 and ball bearing 16 can be installed by reversing the operation.

[0037] The entire device is controlled by a controller. Since the device matched with the controller is a common device and belongs to existing mature technology, its electrical connection relationship and specific circuit structure will not be described in detail here.

[0038] Of all the solutions mentioned above, those involving the connection between two components can be selected according to the actual situation, such as welding, bolt and nut connection, bolt or screw connection, or other known connection methods, which will not be elaborated here. For all the fixed connections mentioned above, welding is preferred. Although embodiments of this utility model have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of this utility model. The scope of this utility model is defined by the appended claims and their equivalents.
