Description

Technical Field

[0001] This utility model relates to the field of gas hoses, and more specifically, it relates to a gas connection hose that is easy to install. Background Technology

[0002] Gas hoses are flexible connecting pipes specifically designed for transporting gas. They are widely used in the connection of equipment such as gas stoves and gas water heaters. To ensure safety and normal use, gas hoses have strict material and performance requirements. The main characteristics of gas hoses are high temperature resistance, corrosion resistance, good flexibility, reliable sealing, and strong pressure resistance. Common types of gas hoses include rubber gas hoses, stainless steel metal hoses (stainless steel corrugated pipes), and composite material hoses.

[0003] For example, Chinese Patent Publication No. CN2804545Y discloses a metal flexible hose with external tapered pipe threads for gas use. This utility model includes a metal corrugated pipe and a pipe fitting with external tapered pipe threads welded to one end of the corrugated pipe. Its distinguishing feature is that the other end of the corrugated pipe has a smooth tube integrally connected to it, with a nut fitted on the smooth tube. Inside the nut is a convex ring integrally connected to the smooth tube, and a sealing washer is located on the outside of the convex ring. This utility model adopts a partially integrated structure, using only one weld, reducing the impact of welding, lowering the probability of gas leakage, and improving safety during use.

[0004] The gas hose and connecting pipe connection method disclosed in the above technical solution is a traditional method. The hose connection is time-consuming and labor-intensive, and additional tools are required. When the hose ages, is damaged or leaks, the maintenance efficiency will be affected when the hose needs to be maintained or replaced.

[0005] Therefore, a new solution is needed to address this problem. Utility Model Content

[0006] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a gas connection hose that is easy to install. The connection component enables the quick connection and disassembly of two gas hoses. The installation and disassembly are convenient, quick and effortless, and the maintenance or replacement of hoses is highly efficient.

[0007] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a convenient gas connection hose, comprising:

[0008] Two hoses;

[0009] A docking assembly for quickly connecting the ends of two hoses. The docking assembly includes a plug and a positioning component, which are respectively disposed at one end of the two hoses. The plug includes a fixing ring fixed to the outer surface of one of the hoses. The fixing ring has an annular groove and at least four through grooves on its outer surface, all of which are connected to the annular groove.

[0010] Each of the four through slots has a rotating plate on its inner side, a positioning strip is fixed on the rotating plate, a drive-opening component is provided on one side of the fixing ring, and a reset component is provided on the inner side of the annular slot.

[0011] By adopting the above technical solution, the drive component pushes the rotating plate, which deflects and squeezes the spring in the reset component, causing the positioning strip to deflect outwards towards the fixed ring. Then, the two hose ends are inserted until they abut against each other. The sliding ring in the drive component is released, and the spring force of the reset component causes the rotating plate to drive the positioning strip into the positioning groove. When the hose needs to be disassembled, the sliding ring is pushed until the positioning strip deflects out of the positioning groove, and the sealing ring on the hose is pulled out of the sealing groove. The disassembly and assembly method is convenient, quick, and labor-saving, and the maintenance or replacement of the hose is highly efficient.

[0012] The present invention is further configured such that: the drive-opening member is used to open the four positioning strips simultaneously; the drive-opening member includes a sliding ring that slides on the outer surface of the fixed ring; at least four push plates are fixed on one side of the sliding ring; and one side of each of the four push plates extends to the inner side of the annular groove.

[0013] The present invention is further configured such that: the reset component includes a spring fixed between the rotating plate and the inner wall of the annular groove, a positive magnetic sheet fixed to one side of the rotating plate, and a negative magnetic sheet fixed to one side of the inner wall of the annular groove.

[0014] The present invention is further configured such that: the positioning element includes a positioning ring fixed to the outer surface of another hose, and the outer surface of the positioning ring is provided with at least four positioning grooves.

[0015] The present invention is further configured such that at least four alignment strips are fixed on the outer surface of the positioning ring.

[0016] The present invention is further configured such that: one end of one of the hoses is provided with a sealing groove, and one end of the other hose is provided with a sealing ring, the sealing ring being correspondingly engaged in the sealing groove.

[0017] In summary, this utility model has the following beneficial effects:

[0018] By pushing the sliding ring towards the outer wall of the fixed ring, the push plate pushes the rotating plate. The rotating plate deflects, squeezing the spring and causing the positioning strip to deflect outwards from the fixed ring. Then, the sealing ring is inserted into the corresponding sealing groove until the ends of the two hoses abut against each other. After aligning the positioning strip and the positioning groove, the sliding ring is released. The spring force causes the rotating plate to drive the positioning strip into the positioning groove. When the hose needs to be disassembled, simply push the sliding ring until the positioning strip deflects out of the positioning groove and pull the sealing ring on the hose out of the sealing groove. The disassembly and assembly method is convenient, quick, and effortless, and highly efficient when maintaining or replacing the hose. Attached Figure Description

[0024] The present invention will be further described in detail below with reference to the accompanying drawings.

[0025] Identical parts are indicated by the same reference numerals. It should be noted that the terms "front," "rear," "left," "right," "up," and "down" used in the following description refer to directions in the accompanying drawings, while the terms "bottom surface," "top surface," "inner," and "outer" refer to directions toward or away from the geometric center of a specific part, respectively.

[0026] like Figure 1-4As shown, a convenient gas connection hose includes two hoses 1 and a connection assembly 2. One end of the hose 1 has a sealing groove 3 on its inner side wall, and the other end of the hose 1 is fixed with a sealing ring 4 whose size matches the sealing groove 3. The sealing ring 4 is correspondingly snapped into the sealing groove 3. The connection assembly 2 is used to quickly connect the ends of the two hoses 1. The connection assembly 2 includes a plug and a positioning component. The plug and the positioning component are respectively set at one end of the two hoses 1. The plug and the positioning component can also be set at both ends of the same hose 1. A positioning component can be fixed to the pipe port connected to the end of the hose 1 with the plug, and a plug can be set to the pipe port connected to the end of the hose 1 with the positioning component, so as to facilitate quick connection between the hose 1 and the connection point.

[0027] The connector includes a fixing ring 21 fixed to the outer surface of one end edge of one of the hoses 1. The fixing ring 21 is provided with an annular groove 22. The outer surface of the fixing ring 21 is provided with at least four through grooves 23, which are equidistant from each other. All four through grooves 23 are connected to the annular groove 22. Rotating plates 24 are rotatably mounted on the inner side of each of the four through grooves 23. The rotating plates 24 are located in the annular groove 22. Positioning strips 25 are fixed on the rotating plates 24 and are provided on the outer side of the fixing ring 21. A drive-opening member is provided on one side of the fixing ring 21. The drive-opening member is used to open the four positioning strips 25 at the same time. The drive-opening member includes a sliding ring 26 that slides on the outer surface of the fixing ring 21. At least four push plates 27 are fixed on one side of the sliding ring 26. The number of push plates 27, the number of through grooves 23, and the number of rotating plates 24 are all the same. One side of each of the four push plates 27 extends to the inner side of the annular groove 22, and each push plate 27 corresponds to one rotating plate 24.

[0028] A reset component is provided inside the annular groove 22. The reset component includes a spring 28 fixed between the rotating plate 24 and the inner wall of the annular groove 22, a positive magnetic sheet 29 fixed to one side of the rotating plate 24, and a negative magnetic sheet 210 fixed to one side of the inner wall of the annular groove 22. The positive magnetic sheet 29 and the negative magnetic sheet 210 are arranged opposite to each other and are located on one side of the push plate 27. The magnetic pole of the positive magnetic sheet 29 is the N pole, and the magnetic pole of the negative magnetic sheet 210 is the S pole. The magnetic attraction between the two helps the rotating plate 24 to reset accurately. Especially when the spring 28 is not elastic enough, it can provide a certain reset force.

[0029] In use: Position the end with the positioning element and the end with the connector opposite each other. Use the index finger and thumb of one hand to push the sliding ring 26 towards the outer wall of the fixed ring 21. The sliding ring 26 will push the push plate 27 connected to it into the annular groove 22. The push plate 27 will push the rotating plate 24 to deflect towards the side where the spring 28 is located. The deflection of the rotating plate 24 will compress the spring 28 and cause the positioning strip 25 to deflect outward from the fixed ring 21. Then, insert the sealing ring 4 into the sealing groove 3 until the ends of the two hoses 1 abut against each other. When the sealing ring 4 is inserted into the sealing groove 3, ensure that each positioning strip 25 is inserted between two adjacent alignment strips 213. Then, start rotating the end of the hose 1 with the fixed ring 21 until the positioning strip 25 and the alignment strip 213 are aligned. With the two hoses 1 facing each other and corresponding to a positioning groove 212, the sliding ring 26 can be released after the ends of the two hoses 1 are abutted. Under the elastic force of the spring 28, the rotating plate 24 is deflected back to its original position. The rotating plate 24 will drive the positioning strip 25 to be locked in the positioning groove 212, thereby realizing the docking of the hoses 1. If the elastic force of the spring 28 fails and fatigues and the rotating plate 24 cannot be fully reset, the magnetic attraction between the positive magnetic sheet 29 and the negative magnetic sheet 210 will help the rotating plate 24 to be fully reset. When it is necessary to disassemble the hoses 1 later, simply push the sliding ring 26 until the positioning strip 25 deflects out of the positioning groove 212 and pull the sealing ring 4 on the hose 1 out of the sealing groove 3. The disassembly and assembly method is convenient, quick and effortless, and does not require additional tools. It is highly efficient when maintaining or replacing hoses.
