DETAILED DESCRIPTION

[0026] The technical solution of the present application will be further described in detail below in conjunction with specific implementation methods.

[0027] The following describes in detail embodiments of the present application. Examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present application and are not to be construed as limiting the present application.

[0028] See also Figures 1 to 12 In one embodiment, a nozzle connection device for a flexible water pipe includes a branch pipe 2, a joint pipe 8, a nozzle 6, and a main pipe 1. The main pipe 1 is fixedly mounted with a plurality of branch pipes 2, and the branch pipe 2 is movably mounted with a joint pipe 8. The main pipe 1 also includes a bellows 3 and an externally threaded plate 26. One end of the joint pipe 8 is connected to the bellows 3, and the end of the bellows 3 away from the joint pipe 8 is connected to a connecting pipe 4. The connecting pipe 4 is connected to a plurality of diversion pipes 5, each of which is provided with a valve. The outer end surface of the diversion pipe 5 is provided with a nozzle 6.

[0029] An external threaded plate 26 is provided on the joint pipe 8, and several curved plates 10 are installed in the branch pipe 2. A third spring 25 is connected between the curved plate 10 and the branch pipe 2. Internal thread grooves 100 are provided on the inner walls of the several curved plates 10. The internal thread grooves 100 cooperate with the external threaded plates 26. A flange 27 is provided at one end of the joint pipe 8, and a flow guide cover 28 is fixedly installed at one end of the branch pipe 2. There is a gap between the flow guide cover 28 and the curved plate 10. The end of the curved plate 10 away from the flow guide cover 28 is fixedly connected to a load-bearing cover 29, and the flange 27 is a spindle ring structure.

[0030] In this embodiment, two branch pipes 5 are connected to the connecting pipe 4 , and the inner diameter of the branch pipe 2 is larger than the inner diameter of the joint pipe 8 .

[0031] During installation, first hold the joint structure, that is, the joint pipe 8 and the flange 27. The inner surface of the load-bearing cover 29 is an inclined surface. The handheld joint structure squeezes the load-bearing cover 29. Under the action of the squeezing force, the curved plate 10 is forced to open. At this time, the joint structure can move vertically at the center of the curved plate 10. When the flange 27 moves to the top of the curved plate 10, the curved plate 10 tends to close inward. Then rotate the joint structure. When the spatial positions of the external threaded plate 26 and the internal threaded groove 100 correspond one to one, the curved plate 10 is under the action of the third spring 25. By closing it from below, that is, the external threaded plate 26 extends into the internal threaded groove 100, completing the vertical locking of the joint structure and the branch pipe 2. At the same time, the deflector 28 is tightly attached to the end of the joint pipe 8, so that the branch pipe 2 and the joint structure can be quickly connected. In the prior art, the connection between the nozzle 6 and the main pipe 1 generally adopts a threaded connection, and the threaded connection requires the nozzle 6 to be in a horizontal position during installation, and it needs to maintain horizontal rotation when manually rotated. The installation of the nozzle 6 is a high-altitude operation, which is inconvenient to operate. It is difficult to ensure its horizontal rotation during installation, and it is easy to misalign.

[0032] When the joint structure needs to be disassembled due to a malfunction or other reasons, since the flange 27 is set as a spindle ring structure, that is, the upper end and the lower end of the flange 27 are both inclined structures, when the load-bearing cover 29 is extruded, the extrusion and expansion effect is better by fitting with the load-bearing cover 29.

[0033] When disassembling, since the external thread plate 26 is engaged with the internal thread groove 100, the joint pipe 8 cannot move vertically. Therefore, the other end of the joint pipe 8 is manually rotated in the opposite direction to make the joint pipe 8 drop until the flange 27 opens the arc plate 10 again. At this time, it can be pulled out with force. Disassembly is achieved by rotation, which can prevent the nozzle head 6 from being detached due to vibration or collision.

[0034] See also Figure 5、 Figure 6 In one embodiment, a guide plug 7 is provided in the connecting pipe 4.

[0035] In this embodiment, by providing a guide plug 7, the inner diameter of the diverter pipe 5 is smaller than the inner diameter of the connecting pipe 4, which can guide the water in the connecting pipe 4 to the diverter pipes 5 on both sides, and the flow rate can be further increased during the guiding process.

[0036] See also Figure 10 In one embodiment, a cover plate 9 is rotatably mounted on one end of the branch pipe 2 located in the main pipe 1 , and a push rod 30 is clamped on one end of the joint pipe 8 located in the branch pipe 2 .

[0037] In this embodiment, an annular groove 81 is provided on the inner wall of the joint pipe 8, and a plurality of fixing blocks 82 are fixedly installed in the annular groove 81. The push rod 30 has an L-shaped structure. When clamping, one end of the push rod 30 is located in the gap between adjacent fixing blocks 82, thereby realizing the clamping of the push rod 30. The rotation plane of the cover plate 9 coincides with the direction of water flow, and the rotation point of the cover plate 9 is closer to the starting point of the water flow.

[0038] During installation, when the flange 27 moves to the top of the arc-shaped plate 10 , the push rod 30 can lift the cover plate 9 , and the water in the main pipe 1 flows into the joint pipe 8 from the open and closed position.

[0039] When disassembling, the push rod 30 is separated from the cover plate 9, and the cover plate 9 rotates under the force of the water flow, so that one end of the branch pipe 2 fits against the cover plate 9 to achieve closure. A sealing gasket is provided on the branch pipe 2.

[0040] See also Figure 10 In one embodiment, the push rod 30 is eccentrically arranged.

[0041] In this embodiment, the opening of the cover plate 9 can be further adjusted by the eccentrically arranged push rod 30, thereby adjusting the flow rate and flow rate.

[0042] During installation, first adjust the position of the push rod 30, which is relative to the end point of the threaded plate at one end of the joint pipe 8. Different positions of the push rod 30 correspond to different openings of the cover plate 9. Then, hold the joint structure, that is, the joint pipe 8 and the flange 27. The inner surface of the bearing cover 29 is inclined. Hold the joint structure and squeeze the bearing cover 29. Under the action of the squeezing force, the curved plate 10 is forced to open. At this time, the joint structure can move vertically at the center of the curved plate 10. During the vertical movement, the push rod 30 During synchronous movement, when the flange 27 moves to the top of the curved plate 10, the curved plate 10 tends to close inward, and the push rod 30 lifts the cover plate 9 at this time, and then rotates the joint structure. When the spatial positions of the external threaded plate 26 and the internal threaded groove 100 correspond one to one, the curved plate 10 is closed under the action of the third spring 25, that is, the external threaded plate 26 extends into the internal threaded groove 100. At this time, the position of the joint pipe 8 is fixed, completing the vertical locking of the joint structure and the branch pipe 2. At the same time, the deflector 28 is tightly attached to the end of the joint pipe 8.

[0043] When disassembling, since the external thread plate 26 is engaged with the internal thread groove 100, the joint pipe 8 cannot move vertically. Therefore, the other end of the joint pipe 8 is manually rotated in the opposite direction to make the joint pipe 8 drop until the flange 27 opens the arc plate 10 again. At this time, the top rod 30 is disengaged from the cover plate 9, and the cover plate 9 rotates under the action of the water flow, so that one end of the branch pipe 2 is fitted with the cover plate 9 to achieve closure, and then the joint structure can be pulled out with force.

[0044] During the disassembly process, the main pipe 1 and the branch pipe 2 can maintain a closed and sealed state. In the prior art, only threaded connection is used, and the disassembly of the nozzle 6 requires water shut-off operation. In the present invention, the disassembly of the joint structure can be performed without shutting off the water.

[0045] See also Figure 1 、 Figure 2 、 Figure 3 In one embodiment, it also includes a frame 14, one end of the frame 14 is installed on the top beam, and sliding frames 16 are slidably installed on both sides of the other end of the frame 14, and a first spring 20 is connected between the sliding frame 16 and the frame 14, and a clamping plate 24 is installed on the sliding frame 16, and the clamping plate 24 is used to clamp the connecting pipe 4.

[0046] In this embodiment, a gear 13 is fixedly mounted on the frame 14, a rack 12 is slidably mounted on the top beam, a first telescopic member 11 is mounted on the wall, the output end of the first telescopic member 11 is connected to the rack 12, and several frames 14 are arranged in the direction of water flow in the main pipe 1. At the same time, several gears 13 are arranged, and the racks 12 are meshed and connected with the several gears 13. The telescopic movement of the first telescopic member 11 drives the several frames 14 to rotate at a small angle, and the rotation angle is less than 90 degrees.

[0047] By providing a rack 12 and a gear 13, the angle of the frame 14 can be fine-tuned. During the actual installation process of the frame 14, it is installed along the branch pipe 2 in the main pipe 1. It is generally installed in a matrix, that is, the telescopic movement of a rack 12 can drive the rotation of several frames 14. The rotation angle of the frame 14 can be generated by judging the position where water needs to be discharged, so that the nozzle 6 is facing the position where water needs to be discharged.

[0048] See also Figure 1 、 Figure 2 、 Figure 3 In one embodiment, a rotating tube 22 is rotatably mounted on the sliding frame 16, a connecting rod 23 is slidably mounted on one end of the rotating tube 22, a second spring 21 is connected between the rotating tube 22 and the connecting rod 23, and a splint 24 is fixedly mounted on one end of the connecting rod 23 away from the rotating tube 22.

[0049] In this embodiment, a pressure rod 17 is placed on the rotating tube 22 connected to the plurality of frames 14 . The pressure rod 17 is located below the plurality of frames 14 , and second telescopic members 15 are installed at both ends of the pressure rod 17 .

[0050] By providing a clamping plate 24, the position of the connecting pipe 4 and the nozzle 6 can be clamped and fixed to avoid being affected by external forces. Secondly, under the action of the second telescopic member 15, the pressure rod 17 can be driven to move, and when the pressure rod 17 moves, the connecting pipes 4 in the same row are driven to descend. The various parameters of the bellows 3 determine the maximum descent height of the connecting pipe 4. When the connecting pipe 4 descends, the water path of the bellows 3 can be extended, so that the water in the connecting pipe 4 can obtain a greater flow rate. The acquisition of a greater flow rate is based on the reduction of the gravitational potential energy of the water body.

[0051] See also Figure 1 、 Figure 2 、 Figure 3 In one embodiment, the other end of the rotating tube 22 is connected to a driving member 19 .

[0052] In this embodiment, the driving member 19 is provided so that the connecting pipe 4 , the diverter pipe 5 and the nozzle 6 can rotate at a certain angle.
