Description

Technical Field

[0001] The utility model relates to the technical field of fire extinguisher filling, in particular to a quick filling interface for fire extinguishers. Background Technique

[0002] Fire extinguishers are indispensable safety devices in daily life and work, providing us with means for initial fire extinguishing, thus avoiding the expansion of fire accidents. However, over time and with use, fire extinguishers need to be refilled to ensure their effectiveness.

[0003] Common fire extinguishers include dry powder, water-based, carbon dioxide, foam, etc. After the filling of a dry powder fire extinguisher is completed and the valve is closed, dry powder will remain inside the interface, which is difficult to remove and causes waste. When filling, after the filling valve is opened, the fire extinguishing agent quickly fills into the fire extinguisher, easily causing a large difference in internal and external air pressure and being unstable. Moreover, there is a certain time difference when the valves at the filling end and the output end are closed, and the fire extinguishing agent inside the fire extinguisher easily clogs the valve. For this reason, we propose a quick filling interface for fire extinguishers. Summary of the Utility Model

[0004] The main purpose of the utility model is to provide a quick filling interface for fire extinguishers, which can effectively solve the problems in the background technique.

[0005] To achieve the above purpose, the technical solution adopted by the utility model is as follows:

[0019] In order to make the technical means, creative features, achieved purposes and effects realized by the present utility model easy to understand, the present utility model will be further described below in conjunction with specific embodiments.

[0020] As Figures 1-4 shown, a quick filling interface for a fire extinguisher includes an interface main body 1, a cleaning structure 2 is embedded and installed on the surface of the interface main body 1, and a filling structure 3 is embedded and installed inside the interface main body 1;

[0021] The interface main body 1 includes a first pipe body 101, a second pipe body 102, an embedding hole 103, a third pipe body 104, a first valve 105, and a second valve 106. An embedding hole 103 is opened on the surface of the second pipe body 102 near the lower position. The first pipe body 101 is embedded and installed on the upper surface of the second pipe body 102. A first valve 105 is embedded and installed on the surface of the first pipe body 101 near the upper position. The third pipe body 104 is embedded and installed on the lower surface of the second pipe body 102. A second valve 106 is embedded and installed on the surface of the third pipe body 104 near the lower position. The cleaning structure 2 includes a third valve 201, a ventilation pipe 202, and an airbag 203. The ventilation pipe 202 is embedded and installed on the surface of the airbag 203. The third valve 201 is embedded and installed on the surface of the ventilation pipe 202. The interface main body 1 and the cleaning structure 2 are embedded and installed in the embedding hole 103 through the ventilation pipe 202. The filling structure 3 includes a conical block 301, a first sleeve 302, a connecting rod 303, a fixed plate 304, an installation ring 305, a sealing ring 306, a spring 307, and a second sleeve 308. The lower surface of the conical block 301 is fixedly installed with the first sleeve 302. When the conical block 301 contacts the first pipe body 101, a seal can be formed between the conical block 301 and the first pipe body 101. The second sleeve 308 is embedded and installed on the lower surface of the first sleeve 302. The sealing ring 306 is fixedly installed on the upper surface of the second sleeve 308. The sealing ring 306 seals the first sleeve 302 and the second sleeve 308, thereby preventing the fire extinguishing agent from entering the inside of the first sleeve 302 through the gap between the first sleeve 302 and the second sleeve 308, causing waste or affecting the expansion and contraction of the spring 307. A spring 307 is fixedly connected between the first sleeve 302 and the second sleeve 308. The lower surface of the second sleeve 308 is fixedly installed with the fixed plate 304. The connecting rod 303 is fixedly installed on the surface of the fixed plate 304. There are four groups of connecting rods 303, and an installation ring 305 is fixedly connected between the connecting rods 303. The filling structure 3 and the interface main body 1 are embedded and installed in the third pipe body 104 near the upper position through the installation ring 305, and the conical block 301 is embedded and installed in the first pipe body 101.

[0022] It should be noted that the present utility model is a quick filling interface for a fire extinguisher. When in use, the interface main body 1 is connected to the fire extinguishing agent tank and the fire extinguisher, and is filled by the filling structure 3. The inside of the interface main body 1 is cleaned by the cleaning structure 2. The first pipe body 101 is connected to the fire extinguishing agent tank, the third pipe body 104 is connected to the fire extinguisher. The air inside the airbag 203 is discharged and the third valve 201 is closed. Then the second valve 106 and the first valve 105 are opened in sequence. After the fire extinguishing agent reaches the inside of the first pipe body 101, it presses the conical block 301, so that the springs 307 inside the first sleeve 302 and the second sleeve 308 are compressed. Since the second sleeve 308 is fixed on the fixed plate 304, and the fixed plate 304 is fixed on the mounting ring 305 through the connecting rod 303, that is, the conical block 301 moves away from the first pipe body 101. After the fire extinguishing agent reaches the inside of the second pipe body 102, it enters the fire extinguisher through the third pipe body 104. After the filling is completed, the first valve 105 and the second valve 106 are closed, and the third valve 201 is opened. The remaining fire extinguishing agent inside the second pipe body 102 reaches the inside of the airbag 203 through the air pipe 202 inside the embedding hole 103.
