Description

Technical Field

[0001] This application relates to the field of fire extinguishers, and in particular to a grip-friendly structure for a water-based fire extinguisher. Background Technology

[0002] Water-based fire extinguishers are a common type of fire extinguishing equipment, widely used in homes, offices, and some small factories. Their main principle is to extinguish fires by spraying water or an aqueous solution. Water-based fire extinguishers typically use water as the extinguishing medium. Compared to other types of fire extinguishers (such as dry powder fire extinguishers and carbon dioxide fire extinguishers), they have advantages such as lower cost, environmental friendliness, non-toxicity, and ease of use. Therefore, they are widely used in many situations. They usually have a simple structure and are held and used by pressing the valve handle.

[0003] However, the handles of some existing water-based fire extinguishers are relatively small, making it difficult to meet the needs of different users, especially those with larger hands or those who need to operate quickly in emergencies. They may feel uncomfortable or unstable when using them. Moreover, since the handles of fire extinguishers are usually fixed and do not have an adjustment function, users may not be able to adjust the grip height according to their needs under different operating conditions, resulting in inconvenience and discomfort during use. Utility Model Content

[0004] This application provides a water-based fire extinguisher with an easy-grip structure. When in use, fire is extinguished by holding the handle, which is convenient for the user to hold. The height of the handle can be adjusted to ensure comfort and stability during operation.

[0005] To achieve the above objectives, this application adopts the following technical solution: a water-based fire extinguisher with an easy-to-grip structure, the structure comprising:

[0006] Fire extinguisher casing;

[0007] The regulating box is fixedly installed on the outer surface of the fire extinguisher shell, and threaded rods are provided on both sides of the inner wall of the regulating box through bearings. The regulating box protects its internal structure and prevents it from being exposed and damaged. The threaded rods can rotate through the bearings.

[0008] The slide cylinder is threaded onto the outer surface of the threaded rod, and two limiting plates are fixedly provided on the outer surface of the slide cylinder, with the two limiting plates having a limiting effect on the slide cylinder;

[0009] Two sliding grooves are respectively opened on both sides of the inner wall of the regulating box, and two limiting plates are respectively slidably set on the inner walls of the two sliding grooves. The two limiting plates can slide on the inner walls of the two sliding grooves, so that when the threaded rod rotates in different directions, the sliding cylinder moves up or down on the outer surface of the threaded rod.

[0010] As a further improvement of this application: a connecting plate is fixedly provided on one side of the slide cylinder, and a knob is fixedly provided on one end of the threaded rod. Rotating the knob in different directions will drive the threaded rod to rotate in different directions.

[0011] As a further improvement of this application: a handle is fixedly provided on one side of the connecting plate, and a rubber cylinder is fixedly sleeved on the outer surface of the handle to increase the friction between the human hand and the handle.

[0012] As a further improvement of this application: a handle is provided on one side of the fire extinguisher housing, and a pressure valve is provided on one side of the handle. By pressing down the pressure valve, the fluid inside the fire extinguisher housing is sprayed to the fire location through the nozzle.

[0013] As a further improvement of this application: a support plate is fixedly provided on one side of the pressure valve, and a horizontal shaft is fixedly provided on the inner wall of the support plate, and the upright can rotate on the outer surface of the horizontal shaft.

[0014] As a further improvement of this application: a vertical rod is movably sleeved on the outer surface of the horizontal shaft, and a pull plate is fixedly installed at one end of the vertical rod. Pulling the pull plate downward will cause the vertical rod to move downward.

[0015] As a further improvement of this application: a positioning rod is movably embedded on one side of the upright pole, and a through hole is opened on the outer surface of the upright pole. The pressure valve is pulled by two support plates, so that the nozzle of the fire extinguisher shell sprays out liquid for fire extinguishing. The position of the pressure valve is fixed by inserting the positioning rod into the handle and the through hole.

[0016] As a further improvement of this application: the positioning rod matches the through hole.

[0017] Compared with the prior art, the advantages and positive effects of this application are as follows:

[0018] 1. In this application, when using the fire extinguisher, the two limiting plates can slide on the inner walls of the two sliding grooves respectively. As the threaded rod rotates in different directions, the sliding cylinder moves up or down on the outer surface of the threaded rod. By rotating the knob in different directions, the threaded rod is driven to rotate in different directions, which further moves the connecting plate to different positions, adjusting the height of the handle. The rubber cylinder increases the friction between the hand and the handle, thereby ensuring the comfort of holding and the stability of operation when using the handle.

[0019] 2. In this application, when the fire extinguisher is in use, pressing down on the pressure valve causes the fluid inside the extinguisher casing to be sprayed onto the fire location through the nozzle. The upright can rotate on the outer surface of the horizontal axis, allowing the positioning rod to be removed from the handle. At this point, pulling down the pull plate moves the upright downward, further actuating the pressure valve via the two support plates, causing the nozzle on the extinguisher casing to spray liquid for fire extinguishing. By inserting the positioning rod into the handle and through hole, the position of the pressure valve is fixed, ensuring that the extinguisher casing continuously sprays fluid. At this time, the operator can hold the handle to extinguish the fire, thus making it convenient for the user to hold the extinguisher while using it. Attached Figure Description

[0025] To better understand the above-mentioned objectives, features, and advantages of this application, the application will be further described below with reference to the accompanying drawings and embodiments. It should be noted that, unless otherwise specified, the embodiments and features described in the embodiments of this application can be combined with each other.

[0026] Many specific details are set forth in the following description in order to provide a full understanding of this application. However, this application may also be implemented in other ways than those described herein, and therefore this application is not limited to the specific embodiments disclosed in the following specification.

[0027] Example 1, such as Figure 1 , Figure 2 and Figure 3As shown, this application provides a grip-friendly structure for a water-based fire extinguisher. The structure includes: a fire extinguisher housing 1; an adjustment box 2, fixedly disposed on the outer surface of the fire extinguisher housing 1, with threaded rods 201 provided on both sides of the inner wall of the adjustment box 2 via bearings; a slide cylinder 202, threadedly sleeved on the outer surface of the threaded rods 201, with two limiting plates 203 fixedly disposed on the outer surface of the slide cylinder 202; two sliding grooves 204, respectively opened on both sides of the inner wall of the adjustment box 2, with the two limiting plates 203 slidably disposed on the inner walls of the two sliding grooves 204; a connecting plate 206 fixedly disposed on one side of the slide cylinder 202; a knob 205 fixedly disposed on one end of the threaded rods 201; a handle 207 fixedly disposed on one side of the connecting plate 206; and a rubber sleeve 208 fixedly sleeved on the outer surface of the handle 207.

[0028] By adopting the above technical solution, the two limiting plates 203 can slide on the inner walls of the two sliding grooves 204 respectively. Then, when the threaded rod 201 rotates in different directions, the sliding cylinder 202 moves up or down on the outer surface of the threaded rod 201. By rotating the knob 205 in different directions, the threaded rod 201 is driven to rotate in different directions, which further moves the connecting plate 206 to different positions, adjusts the height of the handle 207, and increases the friction between the hand and the handle 207 through the rubber cylinder 208.

[0029] Example 2, as Figure 2 and Figure 4 As shown, a handle 3 is provided on one side of the fire extinguisher housing 1, a pressure valve 301 is provided on one side of the handle 3, a support plate 302 is fixedly provided on one side of the pressure valve 301, a horizontal shaft 303 is fixedly provided on the inner wall of the support plate 302, a vertical rod 304 is movably sleeved on the outer surface of the horizontal shaft 303, a pull plate 305 is fixedly provided at one end of the vertical rod 304, a positioning rod 306 is movably embedded on one side of the vertical rod 304, and a through hole 307 is opened on the outer surface of the vertical rod 304, with the positioning rod 306 matching the through hole 307.

[0030] By adopting the above technical solution, by pressing down on the pressure valve 301, the fluid inside the fire extinguisher housing 1 is sprayed to the fire location through the nozzle. The upright 304 can rotate on the outer surface of the horizontal axis 303, and the positioning rod 306 can be removed from the handle 3. At this time, by pulling down the pull plate 305, the upright 304 is moved downward, and the pressure valve 301 is further pulled by the two support plates 302, so that the nozzle of the fire extinguisher housing 1 sprays liquid for fire extinguishing. By inserting the positioning rod 306 into the handle 3 and the through hole 307, the position of the pressure valve 301 is fixed, so that the fire extinguisher housing 1 continuously sprays fluid. At this time, the operator can hold the handle 207 to extinguish the fire, so that when using the fire extinguisher, the operator can hold the handle 207 to extinguish the fire, which is convenient for the operator to hold.

[0031] Working principle: When the fire extinguisher is in use, pressing down on the pressure valve 301 sprays the fluid inside the extinguisher housing 1 through the nozzle to the fire location. The upright 304 can rotate on the outer surface of the horizontal axis 303, removing the positioning rod 306 from the handle 3. Pulling down the pull plate 305 moves the upright 304 downwards, further actuating the pressure valve 301 via the two support plates 302, causing the nozzle of the extinguisher housing 1 to spray liquid for fire extinguishing. Inserting the positioning rod 306 into the handle 3 and the through hole 307 fixes the position of the pressure valve 301, ensuring continuous fluid spraying from the extinguisher housing 1. The operator can then use the handle 207 to extinguish the fire. When using the fire extinguisher, the handle 207 is held by hand for easy gripping. During use, the two limiting plates 203 slide along the inner walls of the two sliding grooves 204. As the threaded rod 201 rotates in different directions, the sliding cylinder 202 moves upwards or downwards on the outer surface of the threaded rod 201. Rotating the knob 205 in different directions rotates the threaded rod 201, further moving the connecting plate 206 to different positions to adjust the height of the handle 207. The rubber cylinder 208 increases the friction between the hand and the handle 207, ensuring comfortable grip and stable operation during use.

[0032] The above are merely preferred embodiments and are not intended to limit the present invention in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present invention without departing from the scope of the present invention shall still fall within the protection scope of the present invention.
