An adjustable flow hose cap

Abstract

This utility model discloses an adjustable flow hose cap, including a main support cap. A connecting rod is fixedly connected to the bottom end of the main support cap, and a connecting ring is horizontally fixedly connected to the bottom end of the connecting rod. Fixed side blocks are symmetrically fixed to the outer side of the connecting ring. The sealing inner ring at the top of the inner side of the main support cap is tightly pressed against the top of the hose, further enhancing the sealing effect. The insertion connection between the extension tube and the top opening of the hose also ensures the sealing of the internal channel. These multiple sealing designs work together to effectively prevent liquid leakage, ensure the reliability of the hose, and guarantee a stable connection between the rotating top plate and the main support cap, preventing the sealing performance from being affected by rotation. Simultaneously, the tight pressing design between the connecting block and the docking half ensures that the sealing of the fluid channel remains unaffected during flow adjustment, guaranteeing the sealing stability of the hose under various usage conditions.

The mating block 9 is set in a semi-circular plate structure, and the bottom end of the mating block 9 is tightly pressed at the top of the mating half 15. The sealing ring 10 is made of soft rubber ring material. The inner snap-fit ​​groove 11 is opened in a ring shape at the top inner side of the main support cover 1 near the edge. The top of the hose is inserted The inner side of the inner locking groove 11 is connected to the inner sealing inner ring 12, and the insertion end is pressed against the bottom surface of the inner sealing inner ring 12.

At the same time, the tight compression design of the block 9 and the docking half 15 also ensures that the sealing of the fluid channel is not affected during the flow adjustment process.

[0029] Working Principle: A groove structure is provided at the center of the bottom end of the main support cover 1. The outer edge of the top of the hose is inserted into the groove for initial positioning. At this time, the connecting rod 2, which is fixedly connected to the bottom end of the main support cover 1, has its top fixed near the edge of the bottom end of the main support cover 1. The sleeve ring 3, which is horizontally fixed to the bottom end of the connecting rod 2, is an open annular structure. The sleeve ring 3 is fitted onto the outer edge of the hose. By using suitable fasteners such as bolts through the fixing through hole 5, the two fixing side blocks 4 are tightened and fixed, so that the sleeve ring 3 is tightly fitted onto the outside of the hose, enhancing the connection stability between the main support cover 1 and the hose. The sealing ring 10 is tightly fitted to the outside of the hose, providing a seal and preventing liquid leakage from the connection between the main support cover 1 and the hose. The extension tube 6, which is fixedly connected to the inner side of the main support cover 1, has its bottom inserted into the inner side of the top opening of the hose, achieving initial communication of the internal channel. The inner top of the main support cover 1 has an annular inner locking groove 11. The top end of the hose is inserted into the inner side of the inner locking groove 11, and the inserted end is pressed against the bottom surface of the sealing inner ring 12 that is locked in the inner side of the inner locking groove 11, further enhancing the sealing effect. The rotating top plate 7 has a through hole 8 that extends through the top surface, and its bottom end extends to connect with the top opening of the through hole 14 that is opened through the top center of the main support cover 1, maintaining continuity. The top end of the extension tube 6 is fixedly connected to the edge of the bottom opening of the through hole 14, forming a complete fluid channel. The mating block 9, which is a semi-circular plate structure, is fixedly installed on the inner side of the through hole 8, and its bottom end is tightly pressed against the top end of the mating half 15 that is fixed on the inner side of the through hole 14. When it is necessary to adjust the flow rate of the fluid in the hose, the rotating top plate 7 is rotated by hand. Since the rotating top plate 7 is locked with the top locking groove 13 of the main support cover 1 through the locking bottom ring 16, it can rotate flexibly. During rotation, the mating block 9 on the inner side of the through hole 8 will misalign with the mating half 15 on the inner side of the through hole 14. When the misalignment between the mating block 9 and the mating half 15 increases, the channel area through which the fluid passes decreases, and the flow rate decreases accordingly; conversely, when rotating the top plate 7 to decrease the misalignment between the mating block 9 and the mating half 15, the channel area through which the fluid passes increases, and the flow rate increases accordingly. This rotational adjustment method allows for convenient control of the fluid flow rate within the hose.
