Description

Technical Field

[0001] The utility model relates to a water hose, in particular to a water hose with a water-dividing connector, and belongs to the technical field of water hoses. Background Art

[0002] In the field of irrigation, a water hose with a water diversion connector is used. The current water hose with a water diversion connector is fixedly connected to the water diversion connector by ultrasonic welding (the water diversion connector uses a plastic part that can be ultrasonically welded with the water hose). The current water diversion connector is a circular piece with a downward boss integrally connected to the lower surface of the circular piece. The upper surface of the circular piece has a positioning ring with the center as the center of the circle. A hole is opened in the center of the circular piece (boss), and a thread is processed in the hole. When water is diverted, the end of the pipe connected to the sprinkler head is connected directly or indirectly to the water diversion connector through the thread. In actual use, this water hose with a water diversion connector has the following characteristics. Problems: First, after the rolled water hose is rolled out during use, the nozzle and the hose need to be connected by threads (adapter), which is troublesome to connect. After use, the screw connection between the nozzle and the hose needs to be removed when rewinding, and the manual operation is tedious and slow. Second, the upper surface of the current water diversion connector is smooth, and the smooth surface and the inner wall of the hose are easily cracked after ultrasonic welding, which will cause water leakage. In addition, the current water diversion connector is made of plastic, and the circular piece and the boss are prone to cracking, which is more common when used in low temperature environments. Water leakage will also occur after cracking. In response to the above problems, the water diversion connector needs to be improved in design. Summary of the Invention

[0003] The purpose of the utility model is to provide a water diversion connecting piece and a water hose with the water diversion connecting piece.

[0004] In order to achieve the purpose of the utility model, the following technical solution is adopted: a water-dividing connector includes a circular piece, a downward boss is integrally connected to the center of the lower surface of the circular piece, a positioning ring is fixedly provided at the center of the upper surface of the circular piece, and a connecting hole that passes through the boss starts from the center of the circular piece. The connecting hole is a plug-in hole, which is a tapered hole with a larger top and a smaller bottom, and the surrounding wall of the tapered hole is smooth.

[0005] Furthermore, a groove begins to appear on the upper surface of the boss, a positioning ring is fixedly connected to the bottom of the groove, the positioning ring and the inner wall of the groove are fixedly connected by a rib plate, the peripheral wall of the upper part of the tapered hole is an inner ring located in the center of the boss, and the outer wall of the inner ring and the positioning ring are fixedly connected by a rib plate.

[0006] Furthermore, the upper surface of the circular piece facing outward of the positioning ring is an uneven rough surface.

[0007] Furthermore, the upper surface of the circular piece has multiple annular protrusions distributed radially, and multiple radial protrusions distributed along the circumferential direction.

[0008] Furthermore, there is an arc-shaped transition between the boss and the lower surface of the circular piece.

[0009] The water hose includes the above-mentioned water diversion connecting piece. A plurality of water diversion connecting pieces are fixedly connected to the water hose. The plurality of water diversion connecting pieces are arranged at intervals. The upper surfaces of the plurality of water diversion connecting pieces are fixedly connected to the inner surface of the water hose by ultrasonic welding.

[0010] The positive and beneficial technical effects of the present invention are: there is a tapered hole in the middle of the water-dividing connector, which can be directly connected to the nozzle with a tapered tube at the end of the pipeline. The connection is very convenient and can be directly pulled out when winding, saving effort and time. The upper surface of the circular piece is a rough surface. After testing, the raised part on the rough surface can be melted after ultrasonic welding, and it is not easy to crack after welding with the inner surface of the water hose. The arc-shaped transition between the boss and the lower surface of the circular piece enhances the strength of this part, making it not easy to crack. BRIEF DESCRIPTION OF THE DRAWINGS

[0015] In order to more fully explain the implementation of the present invention, the following examples are provided. These examples are merely illustrative of the present invention and do not limit the scope of the present invention.

[0016] The present invention is further explained in detail in conjunction with the accompanying drawings, in which the marks are: 100: water-dividing connector; 200: water hose; 1: circular piece; 2: annular protrusion; 3: radial protrusion; 4: positioning ring; 5: inner ring; 6: tapered hole; 7: groove; 8: rib plate; 9: boss; 10: arc-shaped transition.

[0017] As shown in the accompanying drawings, the water-dividing connector 100 includes a circular piece 1, a downward boss 9 is integrally connected to the center of the lower surface of the circular piece, and an arc-shaped transition 10 is formed between the boss and the lower surface of the circular piece. A positioning ring 4 is fixedly provided at the center of the upper surface of the circular piece, and a connecting hole that passes through the boss begins at the center of the circular piece. The connecting hole is a plug-in hole, which is a tapered hole 6 that is larger at the top and smaller at the bottom. Here, the upper part refers to the direction of the circular piece and the lower part refers to the direction of the boss. The peripheral wall of the tapered hole 6 is smooth. In this embodiment, a groove 7 begins to be provided on the upper surface of the boss, and the positioning ring 4 is fixedly connected to the bottom of the groove 4. The positioning ring 4 is fixedly connected to the inner wall of the groove by a rib plate. The peripheral wall of the upper part of the tapered hole is an inner ring 5 located at the center of the boss, and the outer wall of the inner ring 5 is fixedly connected to the positioning ring by a rib plate; 8 shows a rib plate. This design has sufficient expansion (contraction) margin during production, so that the water-dividing connector is not easily deformed.

[0018] As a further optimization, the upper surface of the circular piece facing outward of the positioning ring is a rough surface with uneven bumps. The specific rough surface is: the upper surface of the circular piece has multiple annular protrusions 2 distributed radially and multiple radial protrusions 3 distributed along the circumferential direction.

[0019] The water hose 200 includes the above-mentioned water diversion connector 100. A plurality of water diversion connectors are fixedly connected to the water hose. The plurality of water diversion connectors are arranged at intervals. The upper surfaces of the plurality of water diversion connectors are fixedly connected to the inner surface of the water hose by ultrasonic welding.

[0020] When the hose is used, it is directly connected to the nozzle with a tapered tube at the end of the pipeline. The tapered tube is connected to the tapered hole, and the connection is very firm and will not fall off.

[0021] The ultrasonic welding between the water-dividing connector and the water hose is the same as the ultrasonic welding between the existing water-dividing connector and the water hose.
