Description

Technical Field

[0001] This utility model belongs to the field of water inlet pipe technology, and in particular relates to an anti-electric shock water inlet pipe with adjustable flow rate. Background Technology

[0002] The anti-electric shock inlet pipe is a piping system used to prevent electrical equipment from getting damp, overheating, or short-circuiting. In water heaters and other domestic and commercial water supply systems, the inlet pipe is a key component, and the rationality of its structure and the reliability of its function directly affect the safety of equipment use and maintenance costs.

[0003] Existing water inlet pipes are mostly fixed-length, one-piece structures, unable to be flexibly adjusted to the installation environment, resulting in poor adaptability. If the length is insufficient or excessive, custom-made or replaced pipes are required, increasing installation costs and complexity. Ordinary water inlet pipes lack effective anti-electric shock design; in the event of electrical leakage or a live water system, electricity may be conducted to the user through the water flow, posing a safety hazard. Although some products achieve protection through an external insulation layer, the insulation structure is often integrated with the pipe body, requiring replacement of the entire unit when damaged, resulting in high maintenance costs. Furthermore, flow regulation often relies on threaded valves, controlling water flow by rotating the valve core. After long-term use, the threads are prone to jamming and sealing failure due to wear, corrosion, or scale buildup, leading to decreased adjustment accuracy or even loss of function, requiring frequent replacement of valve components.

[0004] To address these issues, we provide an adjustable-flow-rate anti-electric shock inlet pipe. Utility Model Content

[0005] The purpose of this utility model is to provide an anti-electric shock wall water inlet pipe with adjustable flow rate. By extending the cooperation of the insulation component and the speed regulation component, the problems of the existing anti-electric shock wall water inlet pipes being inflexible to adjust during use, requiring overall replacement, and having easily damaged flow regulation function are solved.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to an adjustable-flow-rate anti-electric shock wall water inlet pipe, comprising an installation ring, a connecting pipe provided on the inner surface of the installation ring, and a baffle plate fixedly connected inside the connecting pipe; an extension insulation assembly provided at the top of the connecting pipe, the extension insulation assembly comprising an extension pipe provided at the top of the connecting pipe and a first insulating sleeve fixedly connected to the surface of the extension pipe; and a speed regulating assembly provided at the bottom of the extension pipe, the speed regulating assembly comprising a rotating rod rotatably connected to one side of the baffle plate and an adjusting plate fixedly connected to one side of the rotating rod.

[0008] The present invention is further configured such that the extended insulation assembly includes a second insulating sleeve fixedly connected to the surface of the connecting pipe, a connecting ring fixedly connected to the surface of the second insulating sleeve, a positioning ring fixedly connected to the surface of the first insulating sleeve, a positioning block fixedly connected to the bottom of the positioning ring, and a sealing ring threadedly connected to the surface of the connecting ring.

[0009] The present invention is further configured such that the speed regulating component includes a spring fixedly connected to one side of the inside of the rotating rod, a movable rod fixedly connected to one side of the spring, a fixed cylinder disposed on one side of the connecting pipe, and a limiting tooth fixedly connected to one side of the movable rod.

[0010] The present invention is further configured such that the bottom of the positioning ring contacts the connecting ring, and the positioning ring and the connecting ring have the same pipe diameter.

[0011] The present invention is further configured such that a positioning groove adapted to the positioning block is provided on the top of the connecting ring, and the positioning ring and the sealing ring are threadedly connected.

[0012] The present invention is further configured such that a slider is fixedly connected to one side of the movable rod, and the slider is slidably connected to one side of the inside of the rotating rod.

[0013] The present invention is further configured such that a handle is fixedly connected to one side of the limiting tooth, and a slot adapted to the limiting tooth is provided on one side of the fixing cylinder.

[0014] The present invention has the following beneficial effects.

[0015] 1. This utility model adopts a segmented extension insulation component design. Through the snap-fit ​​cooperation between the positioning block and the positioning groove, the extension tube can be quickly disassembled and the quantity can be adjusted. This effectively solves the problem of poor adaptability caused by the fixed length of the traditional water inlet pipe, reduces the customization or replacement cost caused by size mismatch, and sets up an insulation sleeve. Combined with the threaded sealing structure of the sealing ring, an insulation protection system is formed to block the risk of current conduction in the water flow path, avoid the safety hazards caused to users by leakage or water circuit electrification, and significantly improve the safety of equipment use.

[0016] 2. This utility model innovatively adopts a spring and limit tooth self-locking mechanism. By pulling the handle to release the limit tooth from its locked state, the opening and closing angle of the adjusting plate and the blocking plate can be freely adjusted to achieve stepless flow rate control. After adjustment, the limit tooth automatically resets and locks, avoiding the jamming failure problem caused by wear of traditional threaded valves, improving adjustment accuracy and service life. The modular design of the extension tube and insulating sleeve supports independent replacement without the need to replace the entire pipeline, reducing later maintenance costs. The segmented structure facilitates local inspection and maintenance, improving equipment maintainability.

[0017] Of course, any product implementing this utility model does not necessarily need to achieve all of the advantages described above at the same time. Attached Figure Description

[0028] Example 2

[0029] Please see Figures 1-5 Based on Embodiment 1, the extended insulation assembly further includes a second insulating sleeve 8 fixedly connected to the surface of the connecting pipe 2. The bottom of the first insulating sleeve 5 contacts the second insulating sleeve 8. A mounting ring 1 is fixedly connected to the surface of the second insulating sleeve 8. The surface of the mounting ring 1 is provided with a connecting thread for installation. The first insulating sleeve 5 and the second insulating sleeve 8 have the same pipe diameter. A connecting ring 9 is fixedly connected to the surface of the second insulating sleeve 8. A positioning ring 10 is fixedly connected to the surface of the first insulating sleeve 5. Both the connecting ring 9 and the positioning ring 10 are provided with connecting threads for connecting a sealing ring 12. A positioning block 11 is fixedly connected to the bottom of the positioning ring 10. A sealing ring 12 is threadedly connected to the surface of the connecting ring 9. The speed regulating assembly also includes a spring 13 fixedly connected to one side of the inside of the rotating rod 6. A movable rod 14 fixedly connected to one side of the spring 13. A fixed cylinder 15 is provided on one side of the connecting pipe 2. The fixed cylinder 15 is fixed to the second insulating sleeve 8. The rotating rod 6 extends from the end away from the adjusting plate 7 into the interior of the fixed cylinder 15. The rotating rod 6 is movably connected to the connecting pipe 2, the second insulating sleeve 8, and the fixed cylinder 15 through sealed bearings. The limiting tooth 16 is fixedly connected to one side of the moving rod 14. The bottom of the positioning ring 10 contacts the connecting ring 9. The positioning ring 10 and the connecting ring 9 have the same pipe diameter. The top of the connecting ring 9 has a positioning groove 17 that matches the positioning block 11. The top surface of the first insulating sleeve 5 is also fixedly connected to the connecting ring 9 with the positioning groove 17. The positioning block 11 is engaged in the positioning groove 17. The positioning ring 10 and the sealing ring 12 are threadedly connected. A slider is fixedly connected to one side of the moving rod 14. The slider is slidably connected to one side of the inside of the rotating rod 6. A sliding groove that matches the slider is opened on one side of the inside of the rotating rod 6. A handle is fixedly connected to one side of the limiting tooth 16. A slot 18 that matches the limiting tooth 16 is opened on one side of the fixed cylinder 15. The limiting tooth 16 is engaged in the slot 18.

[0030] The working principle of this utility model is as follows: the connecting pipe 2 is fixed to the designated position by the connecting thread of the mounting ring 1, ensuring that the positioning block 11 is accurately embedded in the positioning groove 17, thereby achieving axial positioning of the extension pipe 4 and the connecting pipe 2. The sealing ring 12 is rotated to make it tightly threadedly connected with the positioning ring 10. At this time, the positioning ring 10 seals the contact position of the extension pipe 4, the connecting pipe 2, the first insulating sleeve 5, and the second insulating sleeve 8. The sealing ring 12 seals the contact point of the connecting ring 9 and the positioning ring 10, forming multiple sealing barriers to prevent water leakage. The number of extension pipes 4 can be increased according to the actual situation. During maintenance, it can be disassembled and maintained in sections, reducing maintenance costs.

[0031] The first insulating sleeve 5 and the second insulating sleeve 8 cover the outer wall of the pipeline to achieve insulation. The threaded engagement between the sealing ring 12 and the positioning ring 10 further enhances the insulation integrity, ensuring electrical isolation throughout the pipeline system. When adjusting the flow rate, pull the limiting tooth 16 outward with the handle, stretching the spring 13 and releasing it from its engagement with the slot 18 of the fixed cylinder 15. At this time, the rotating rod 6 is in a rotatable state. Rotating the handle drives the rotating rod 6 and the adjusting plate 7 to rotate synchronously. By changing the opening and closing degree of the adjusting plate 7 and the blocking plate 3, the flow rate of the water channel is adjusted, thereby controlling the flow rate. After releasing the handle, the spring 13 rebounds and drives the limiting tooth 16 to re-engage with the corresponding slot 18 of the fixed cylinder 15, fixing the position of the adjusting plate 7 and maintaining a stable flow rate. Through the combination of mechanical linkage and material insulation properties, precise control of the flow rate is achieved while ensuring safety, making it suitable for various fluid transmission scenarios.
