Description

Technical Field

[0001] This utility model relates to the field of gas pipe technology, specifically a metal-coated flexible hose for quick connection of gas appliances. Background Technology

[0002] Gas hoses are used when connecting gas pipelines to gas valves or gas stoves. Existing gas hoses are all flame-retardant PVC hoses, and good sealing and firmness are required when connecting them.

[0003] A search of existing published patents (patent number 201621036660.6, titled "A Connection Structure for a Connecting Hose and a Gas Stove External Connector") reveals that the structure includes a straight plug for the gas stove and a straight insertion port for the connecting hose. The straight plug is inserted into the straight insertion port with an interference fit. The straight insertion port has a connecting buckle on its exterior, consisting of a buckle element, a connecting bolt, and a nut. The buckle element is a notched annular elastic body, which bends upwards at the notch to form two connecting portions, each with a corresponding connecting hole. The connecting bolt passes laterally through the two connecting holes and connects to the nut. The straight insertion port has a protruding stop ring at its opening and a tapered reinforcing protrusion on the inner side of the connecting buckle. This invention adds a connecting buckle to the interference fit between the connecting hose and the external connector, effectively enhancing the connection and preventing detachment during use, thus ensuring safety during connection and use.

[0004] However, when using the above connection structure, after a period of time, the connecting clips may loosen, and the gas hose may fall off naturally, so the safety of use is still not ideal. Utility Model Content

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0025] Example 1:

[0026] Please see Figure 1-4 The present invention provides a technical solution: a gas pipe 1, a connecting seat 2 integrally formed at one end of the gas pipe 1, an installation seat 3 connected to one side of the connecting seat 2, a sealing seat 4 fixedly connected to one end of the installation seat 3, a connecting port 8 opened on one side of the sealing seat 4, and a sealing component 5 provided on the sealing seat 4.

[0027] The sealing assembly 5 includes a sealing cylinder 501 fixedly connected to the surface of the sealing seat 4. A sealing cover 502 is fixedly connected to the top of the sealing cylinder 501. A threaded rod 503 is threadedly connected to the sealing cover 502. A piston 504 is rotatably connected to the bottom of the threaded rod 503. The piston 504 is slidably connected to the inner wall of the sealing cylinder 501. An adjusting block 505 is fixedly connected to the top of the threaded rod 503. A second sealing block 508 and a first sealing block 507 are fixedly connected sequentially from the outside to the inside of the communication port 8. Both the second sealing block 508 and the first sealing block 507 communicate with the bottom of the sealing cylinder 501. The connecting seat 2, the mounting seat 3, and the sealing seat 4 are all provided with stainless steel seats. The connecting head 7 is inserted into the communication port 8.

[0028] Analysis of the above: A sealing assembly 5 is installed. When the connector 7 is inserted into the connecting port 8, rotating the adjusting block 505, through its interaction with the sealing cover 502, causes the sealing cover 502 to move the piston 504 downwards along the inner wall of the sealing cylinder 501. This forces the nitrogen gas at the bottom of the sealing cylinder 501 into the first sealing block 507 and the second sealing block 508. The first and second sealing blocks 507 expand under the pressure of the gas, contacting the connector 7 and sealing the connecting port 8 to prevent leakage. The sealing effect is good, preventing natural detachment. The connector 2, mounting base 3, and sealing base 4 are all equipped with stainless steel seats to extend their service life. One end of the connector 7 is fixedly connected to a pressure reducing valve 6.

[0029] Example 2:

[0031] Analysis of the above: The arc-shaped groove 509 is designed to make the first sealing block 507 and the second sealing block 508 fit more closely to the outer surface of the connector 7, thus improving the sealing performance. The first sealing block 507 and the second sealing block 508 are filled with nitrogen gas, which provides pressure and ensures that the connector 7 will not fall out of the communication port 8.

[0032] Example 3:

[0033] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: a connecting groove 506 is provided at the center of the top of the adjusting block 505, and a threaded hole matching the threaded rod 503 is provided on the sealing cover 502.

[0034] Analysis of the above content: The connecting groove 506 is set to facilitate the rotation of the adjusting block 505, thereby driving the piston 504 to move up and down.

[0035] Example 4:

[0036] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: a limiting ring 510 is fixedly connected to the top of the sealing cylinder 501, and the thickness of the limiting ring 510 is the same as the thickness of the adjusting block 505.

[0037] Analysis of the above content: The limit ring 510 is set so that when the adjusting block 505 moves to the lower left, the top of the adjusting block 505 is flush with the limit ring 510, which prevents the adjusting block 505 from being accidentally rotated and prevents air leakage caused by the contraction of the first sealing block 507 and the second sealing block 508, thus improving safety.

[0038] Example 5:

[0039] Please see Figure 1-4 Based on Embodiment 1, this utility model provides a technical solution: both the first sealing block 507 and the second sealing block 508 are configured as corrosion-resistant rubber blocks.

[0040] Analysis of the above content: The first sealing block 507 and the second sealing block 508 are set as anti-corrosion rubber blocks to extend service life and avoid corrosion from gas.

[0041] Example 6:

[0042] Please see Figure 1-4 The present invention provides a technical solution based on Embodiment 1: the gas pipe 1 includes a corrosion-resistant pipe 101 connected to the connecting seat 2, a stainless steel corrugated pipe 102 fixedly connected to the surface of the corrosion-resistant pipe 101, and a flame-retardant pipe 103 fixedly connected to the surface of the stainless steel corrugated pipe 102.

[0043] Analysis of the above content: Anti-corrosion pipe 101 is set to prevent gas pipe 1 from being corroded by gas; stainless steel corrugated pipe 102 is set to improve the structural strength of gas pipe 1 and prevent it from being torn by rats and other animals; flame-retardant pipe 103 is set to improve fire resistance and improve the safety of gas pipe 1.
