Description

Technical Field

[0001] This utility model relates to the field of gas transmission and pipeline connection technology, and in particular to an adjustable gas corrugated pipe. Background Technology

[0002] In gas applications, connecting pipes are key components between the pipeline and terminal equipment. Rubber hoses are flexible and inexpensive, but have a short lifespan of only 18 months to 2 years. They are prone to rupture and leakage due to aging, rodent bites, and external pulling. Statistics show that over 30% of gas accidents are caused by them. Metal-coated hoses are durable, but their fixed length and angle make them unsuitable for complex installation scenarios (such as kitchens and industrial gas equipment). In homes, gas water heaters are becoming increasingly powerful, requiring greater stability in gas flow and pressure. Integrated stoves have rich functions, resulting in more complex installation spaces and interface layouts. Given the importance of gas safety, local governments and departments have introduced stricter management regulations, with higher requirements for the material, sealing, and service life of connecting pipes, emphasizing the use of safe and highly adaptable products.

[0003] However, existing adjustable gas bellows have the following disadvantages:

[0004] There are many brands and models of gas equipment, and their interface specifications and types vary. It is difficult to find all commonly used gas corrugated pipes that can be used, resulting in poor utilization.

[0005] Therefore, this utility model provides an adjustable gas bellows. Utility Model Content

[0006] The technical problem solved by this utility model is to provide an adjustable gas bellows that is highly practical, easy to operate, and has a simple structure, thus solving the problem mentioned in the background art that commonly used gas bellows are difficult to fully adapt.

[0007] To achieve the above objectives, this utility model is implemented through the following technical solution: an adjustable gas corrugated pipe, including a pipe body, a connector installed at one end of the pipe body, and a disassembly component provided on the inner side wall of the connector;

[0008] The disassembly assembly includes a connecting tube slidably connected inside the connector. The surface of the connecting tube has a slot, and the surface of the connector has an annular groove. The inner sidewall of the annular groove has a sliding hole, and a clamp is slidably connected to the inner sidewall of the annular groove. A spring is connected between the clamp and the inner bottom wall of the annular groove. A slider is slidably connected to the inner sidewall of the sliding hole. One side of the slider contacts the inside of the clamp, and the other side of the slider is engaged inside the slot.

[0009] Optionally, a limiting groove is formed on the inner sidewall of the sliding hole, and a limiting block is slidably connected to the inner sidewall of the limiting groove. One side of the limiting block is fixedly connected to one side of the slider. By setting the limiting block, the slider can move in a fixed position.

[0010] Optionally, a rubber sleeve is installed on the surface of the tube body to enhance the corrosion resistance of the tube body.

[0011] Optionally, the surface of the tube body is provided with a retaining ring, which is circular in shape, and the retaining ring facilitates better clamping of the tube body.

[0012] Optionally, the surface of the retaining ring is fixedly connected to a mounting block, and both mounting blocks are threaded with bolts. The bolts prevent leakage at the pipe joint.

[0013] Optionally, the surface of the clamp is fitted with an anti-slip sleeve, and the number of anti-slip sleeves is one. The anti-slip sleeve is provided to prevent slippage when replacing parts.

[0014] This utility model provides an adjustable gas bellows, which has the following advantages:

[0015] 1. This adjustable gas bellows, through the connecting pipe, clamp, spring, and slider, allows for easy replacement of other connecting parts. First, press one end of the clamp to the appropriate position while simultaneously squeezing the spring to pull out the connecting pipe. At the same time, squeezing and pushing the slider moves it. Then, when replacing other connecting parts, the slider engages with the slot under the action of the spring, thus completing the replacement. It can flexibly switch the connector between different devices, adapt to various gas equipment interfaces, improve utilization, and reduce operating costs. Attached Figure Description
