The fixing piece 21 is provided with a first passage 210, and the rotating piece 22 is provided with a second passage 220. Rotating the rotating piece 22 can adjust the communication area of the first passage 210 and the second passage 220 to adjust the flow rate of the water flowing through the first fire hose 100, thereby achieving the purpose of adjusting the water pressure. Specifically, when the first passage 210 and the second passage 220 are completely communicated, the flow rate of the water flowing through the first fire hose 100 is the largest; rotating the rotating piece 22 to make part of the first passage 210 and part of the second passage 220 communicate can reduce the flow rate of the water flowing through the first fire hose 100, thereby achieving the purpose of increasing the water pressure, increasing the water jet distance, avoiding the operator from being burned due to being close to the fire, and protecting the personal safety of the operator.
[0043] Specifically, the first end of the first connector 11 is welded with the end of the first fire hose 100, and the first end of the second connector 12 is welded with the end of the second fire hose 200.
[0044] Optionally, referring to Figure 1 , the second end of the first connector 11 is provided with a plurality of clamping pieces 111 at intervals in the circumferential direction. Referring to Figure 2 , the second end of the second connector 12 is provided with a plurality of clamping parts 120 at intervals in the circumferential direction, and the plurality of clamping parts 120 are correspondingly clamped in the clamping grooves 1110 of the plurality of clamping pieces 111 to further improve the connection stability of the first connector 11 and the second connector 12.
[0045] Exemplarily, in the embodiment, the clamping pieces 111 and the clamping portions 120 are both provided with four; in other embodiments, the specific number of the clamping pieces 111 and the clamping portions 120 can be set as needed, which is not limited here.
[0046] Optionally, as shown in Figure 1 and Figure 2 , the second end of the second connector 12 is rotationally provided with a rotating plate 121, and the clamping portion 120 is arranged on the rotating plate 121. When it is needed to connect the first fire hose 100 and the second fire hose 200, the end of the second fire hose 200 does not need to be rotated, and only the rotating plate 121 needs to be rotated to slide the clamping portion 120 into the clamping groove 1110, which is simple and convenient to operate, and can effectively avoid the phenomenon of self-winding and knotting of the second fire hose 200, so as to ensure the smooth flow of water after connection.
[0047] Further, referring to Figure 3 , the rotating plate 121 is protrudingly provided with a limiting ring 1211, and when the clamping portion 120 is clamped in the clamping groove 1110, the limiting ring 1211 extends into the first connector 11 and abuts against the inner wall of the first connector 11. When the first fire hose 100 and the second fire hose 200 are connected, the limiting ring 1211 is aligned with the first connector 11 and extends into the first connector 11, and at the same time, the limiting ring 1211 abuts against the inner wall of the first connector 11 in the circumferential direction, and then the rotating plate 121 is rotated to slide the clamping portion 120 into the clamping groove 1110, so that the clamping of the clamping portion 120 and the clamping groove 1110 is completed. The limiting ring 1211 can realize preliminary positioning of the connection and improve the connection efficiency.
[0048] Further, the outer peripheral wall of the limiting ring 1211 is provided with a waterproof coating to seal the gap at the connection between the first connector 11 and the second connector 12, so as to prevent water leakage. Specifically, the waterproof coating is a known substance, and its specific components refer to the prior art, which will not be described here.
[0049] Optionally, the outer peripheral wall of the rotating plate 121 is provided with a first anti-skid structure. The first anti-skid structure can be a non-slip pad such as a rubber pad, or an anti-skid protrusion which can be a point-shaped protrusion or a protrusion with any shape of lines, which is used to increase the friction between the hands of the operator and the outer peripheral wall of the rotating plate 121 to avoid hand slipping during rotation. The specific form thereof refers to the prior art, which is not limited in the embodiment, as long as it can increase the friction.
[0050] Optionally, the second end of the first connector 11 is provided with a fixed plate 112, and the plurality of clamping pieces 111 are arranged on the fixed plate 112. Referring to Figure 4 and Figure 5The clamping piece 111 includes two arc-shaped plates arranged at intervals, and a clamping groove 1110 for limiting the clamping part 120 is formed on the side of the two arc-shaped plates facing each other.
[0051] Optionally, as shown in Figure 6 The rotating member 22 is arranged on the side of the fixing member 21 facing the rotating member 22, and the rotating member 22 is arranged on the rotating shaft 211 in a sleeving manner and abuts against the fixing member 21.

[0052] Further, the rotating member 22 is provided with a second anti-skid structure on the outer circumferential wall. The second anti-skid structure can be a non-slip pad such as a rubber pad, or an anti-skid protrusion. The anti-skid protrusion can be a point-shaped protrusion or a protrusion with an arbitrary shape of a pattern. The anti-skid protrusion is used to increase the friction between the hands of an operator and the outer circumferential wall of the rotating member 22, so as to avoid the hands of the operator from slipping during rotation. The specific form of the anti-skid protrusion can refer to the prior art, and is not limited in the embodiment.
[0053] Optionally, continuing to refer to Figure 6 The fixing member 21 is provided with a plurality of first channels 210 arranged at intervals in the circumferential direction, and the rotating member 22 is provided with a plurality of second channels 220 arranged at intervals in the circumferential direction, so as to uniformly distribute the water flow, avoid the water flow from being concentrated or flowing at a high speed in a local area, improve the uniformity of the flow distribution in the pipeline, and reduce the amplitude of the fire hose. Specifically, in the embodiment, the fixing member 21 is provided with two first channels 210 arranged at intervals, and the rotating member 22 is provided with two second channels 220 arranged at intervals. In other embodiments, the specific number of the first channels 210 and the second channels 220 can be arranged as required, and is not limited herein.
[0054] More specifically, in the embodiment, the cross sections of the first channels 210 and the second channels 220 are in the shape of a sector. The sector-shaped cross section can reduce the flow separation of the water flow, reduce the formation of vortexes, reduce the local water head loss of the water flow, make the water flow speed distribution more uniform, and further improve the water flow conveying efficiency.
[0055] Optionally, as shown in Figure 1 and Figure 2As shown, the first fire hose 100 and / or the second fire hose 200 is provided with a water pressure monitor 3 configured to monitor the water flow pressure to monitor the water flow pressure in the water hose in real time, ensure that the water flow pressure is maintained within a reasonable range, and avoid excessive water pressure from impacting the equipment such as the water pump or the valve.
