Description
Technical Field
[0001] This utility model relates to the field of gas purification tube technology, specifically a gas purification tube with a convenient fixing mechanism. Background Technology
[0002] Gas purification tubes are used to filter and purify gases when installed on hydrogen generators. They are commonly used gas purification devices on hydrogen generators, and as the use of hydrogen generators becomes more widespread, the demand for gas purification tubes has increased.
[0003] For example, the authorization announcement number "CN211659494U" describes a gas purification tube with a convenient fixing mechanism. This mechanism, consisting of a strap fixing seat, a left-side strap, a positioning ring, a right-side strap, and a positioning hole, allows for quick and easy fixation of the gas purification tube, providing convenience for various applications. However, existing gas purification tubes with convenient fixing mechanisms often have limitations. They employ a structure at both ends inside the tube body that purifies and adsorbs the passing gas. While the tube can be disassembled to remove and replace the filler when necessary, the filler is fully inserted into the tube, and the tube opening is relatively narrow, making it inconvenient for operators to manually remove it. Furthermore, the purified filler adheres more firmly to the inner wall of the tube, hindering its removal. This requires operators to manually pull out the filler with a long, thin tool, resulting in inconvenience, wasted time, and negatively impacting the ease of use of gas purification tubes with convenient fixing mechanisms.
[0004] Meanwhile, existing gas purification tubes with convenient fixing mechanisms use straps that can be bent and wrapped twice to facilitate fixing the gas purification tube. However, when the straps are relatively long and need to be fixed, there must be a cylindrical or square column or other support point to provide support for the straps to be wrapped and fixed. However, when the gas purification tube is installed on a flat wall or a flat and smooth surface without a structure for the straps to be wrapped and fixed, the fixing method of the straps will be limited. Therefore, the convenient fixing method of existing gas purification tubes with convenient fixing mechanisms has limited adaptability. Utility Model Content
[0005] The purpose of this utility model is to solve the problems of inconvenience in using gas purification tubes with convenient fixing mechanisms and limited adaptability of fixing methods, and to propose a gas purification tube with a convenient fixing mechanism.
[0006] To achieve the above objectives, this utility model provides the following technical solution:
[0007] Design a gas purification tube with a convenient fixing mechanism, including a gas purification tube body, a lower end, and an upper end. The lower end is movably installed at the lower end of the gas purification tube body, and the upper end is movably installed at the top end of the gas purification tube body. The inner sides of the upper and lower ends are provided with pipe docking installation structures. The inner side of the gas purification tube body is provided with a filler for easy removal. One side of the outer wall of the gas purification tube body is provided with a flat convenient fixing structure, and the other side of the gas purification tube body is provided with a pipe clamp fixing structure.
[0008] Preferably, the pipe connection installation structure includes a sealing gasket and a venting cavity. The two venting cavities are respectively opened on the inner side of the upper end and the lower end. The two sealing gaskets are fixedly installed on both ends of the outer wall of the upper end and the lower end. Two threaded heads are fixedly installed on the outside of the two sealing gaskets, and through holes are fixedly opened on the inner side of the two threaded heads.
[0009] Preferably, the end of the through hole is connected to the inside of the ventilation chamber, and the other end of the two ventilation chambers is connected to the two ends of the inside of the gas purification pipe body.
[0010] Preferably, the filler removal structure includes a splicing pipe and a removal bracket. Two removal brackets are slidably connected to both ends of the gas purification tube body. Two splicing pipes are fixedly installed at the other ends of the two removal brackets. The two splicing pipes are threaded to the inner side of the gas purification tube body. The other ends of the two splicing pipes are fixedly connected to the inner side of the upper end and the lower end, respectively. Filter filler is movably connected to one side of the inside of the removal bracket, and dry filler is movably connected to the other side of the inside of the removal bracket. Separating sponges are movably connected to the ends of the two removal brackets.
[0011] Preferably, the planar convenient fixing structure includes a first bonding block and a first bolt. The first bonding block is movably connected to one side of the outer wall of the gas purification pipe body. Two first bolts are threaded to both ends of the first bonding block. The ends of the two first bolts are threaded to the outer wall of the gas purification pipe body. Multiple fixing suction cups are fixedly installed on the outer wall of the first bonding block.
[0012] Preferably, the pipe clamp fixing structure includes a second fitting block and a positioning hole. The second fitting block is movably connected to the other side of the outer wall of the gas purification pipe body. The two ends of the second fitting block are threaded with second bolts. The ends of the two second bolts are threaded to the outer wall of the gas purification pipe body. A rotating shaft is rotatably connected to the inner side of the second fitting block. A movable hoop is rotatably connected to the outer wall of the rotating shaft. A fixed hoop is fixedly installed on the outer wall of the second fitting block. The positioning hole is fixedly opened on the outer wall of the fixed hoop. The end of the movable hoop is movably connected to the positioning hole.
[0013] The present invention proposes a gas purification tube with a convenient fixing mechanism, which has the following advantages: when it is necessary to remove and replace the filler, the upper and lower ends can be directly twisted in the opposite direction to drive the splicing pipe away from both ends of the gas purification tube body. Then, the splicing pipe can be pulled outward along with the two side removal brackets. The removal brackets can remove the inner filler together, which is convenient for replacement. Not only does it not require additional tools, but it also saves time and improves the ease of use of the gas purification tube with the convenient fixing mechanism.
[0014] The first bonding block is made of stainless steel, and the curvature of its inner side matches the curvature of the outer wall of the gas purification tube. By rotating the first bolt on the outside, the first bonding block, along with the front-end fixing suction cup, can be installed on the outside of the gas purification tube. The fixing suction cup is made of silicone and is designed with a bowl-shaped structure. When the installation location is a flat surface lacking a fixing object, the fixing suction cup can be directly attached to the flat surface by air pressure difference, providing a more convenient installation structure and improving the ease of installation and adaptability of the gas purification tube with a convenient fixing mechanism.

[0022] The present invention will be further described below with reference to the accompanying drawings:
[0023] Example 1:
[0024] Please see Figure 1-6 In this embodiment, a gas purification tube with a convenient fixing mechanism includes a gas purification tube body 1, a lower end 2, and an upper end 3. The lower end 2 is movably installed at the lower end of the gas purification tube body 1. The lower end 2 and the upper end 3 are respectively located at the upper and lower ends of the gas purification tube body 1. The inner sides of the lower end 2 and the upper end 3 are connected to the inside of the gas purification tube body 1 through the outer thread of the splicing pipe 51. The upper end 3 is movably installed at the top end of the gas purification tube body 1. The inner sides of the upper end 3 and the lower end 2 are provided with a pipe docking installation structure 4. The inner side of the gas purification tube body 1 is provided with a filler material for easy removal structure 5. One side of the outer wall of the gas purification tube body 1 is provided with a planar convenient fixing structure 6, and the other side of the gas purification tube body 1 is provided with a pipe clamp fixing structure 7.
[0025] The pipe connection installation structure 4 includes a sealing gasket 41 and a venting chamber 44. The two venting chambers 44 are respectively opened on the inner side of the upper end 3 and the lower end 2. The venting chambers 44 are used to guide the gas entering the gas purification pipe body 1 into the pipe or lead it out into the through hole 43, playing a transition role. The two sealing gaskets 41 are fixedly installed on the outer walls of the upper end 3 and the lower end 2. The sealing gaskets 41 are made of rubber material. The rubber sealing gaskets 41 can improve the sealing effect at the pipe joint after the lower end 2 and the upper end 3 are connected to the external pipe.
[0026] Two threaded heads 42 are fixedly installed on the outside of the two sealing gaskets 41. The hollow part inside the threaded head 42 is set as a through hole 43 for ventilation. The threaded head 42 can be rotated and screwed into the middle of the hydrogen generator pipe that needs to be purified. The through hole 43 is fixedly opened on the inner side of the two threaded heads 42. The end of the through hole 43 is connected to the inner side of the ventilation chamber 44. The other end of the two ventilation chambers 44 is connected to the two ends of the gas purification pipe body 1.
[0027] The filler is easy to pull out. The structure 5 includes a splicing pipe 51 and a take-out bracket 52. The two take-out brackets 52 are slidably connected to the two ends inside the gas purification tube body 1. The take-out brackets 52 are made of stainless steel and adopt a cylindrical frame structure made of four metal strips welded together. The diameter of the take-out brackets 52 is slightly smaller than the inner diameter of the gas purification tube body 1. The two ends of the take-out brackets 52 are connected to the inner wall of the splicing pipe 51. In this way, the splicing pipe 51 can be fixed by screwing it into the inner side of the end of the gas purification tube body 1 using the outer thread. The other end of the two take-out brackets 52 is fixedly installed with two splicing pipes 51.
[0028] Two connecting pipes 51 are threaded to the inside of the gas purification tube body 1. The other ends of the two connecting pipes 51 are fixedly connected to the inside of the upper end 3 and the lower end 2, respectively. A filter filler 53 is movably connected to one side of the inside of the take-out rack 52. The filter filler 53 can be manually inserted into the four-sided gaps inside the take-out rack 52. The filter filler 53 is made of activated carbon material and has good filtration and adsorption functions. A dry filler 55 is movably connected to the other side of the inside of the take-out rack 52. The dry filler 55 is inserted into the inside of the other take-out rack 52. The dry filler 55 is made of silica gel particles and can absorb excess moisture inside the gas.
[0029] The ends of the two removal racks 52 are movably connected to a separating sponge 54. The separating sponge 54 serves to separate the two adjacent removal racks 52 and their internal filling materials. When it is necessary to remove the filling materials for replacement, simply twist the upper end 3 and the lower end 2 in the opposite direction to drive the splicing pipe 51 away from both ends of the gas purification pipe body 1. Then, the two removal racks 52 on both sides can be pulled outward through the splicing pipe 51. The removal racks 52 can be removed together with the internal filling materials, which is convenient for replacement. It not only does not require additional tools, but also saves more time.
[0030] The extraction frame 52 is made of stainless steel and is a cylindrical frame structure made of four metal strips welded together. The diameter of the extraction frame 52 is slightly smaller than the inner diameter of the gas purification tube body 1. In this way, the splicing pipe 51 can be fixed by screwing the outer thread into the inner side of the end of the gas purification tube body 1.
[0031] When the filler needs to be removed for replacement, simply twist the upper end 3 and the lower end 2 in the opposite direction to move the splicing pipe 51 away from both ends of the gas purification pipe body 1. Then, pull it outward through the splicing pipe 51 along with the two side removal brackets 52. The removal brackets 52 can remove the inner filler together, making it convenient for replacement. This not only eliminates the need for additional tools but also saves time and improves the ease of use of the gas purification pipe with a convenient fixing mechanism.
[0032] The planar convenient fixing structure 6 includes a first bonding block 61 and a first bolt 62. The first bonding block 61 is movably connected to one side of the outer wall of the gas purification tube body 1. The first bonding block 61 is made of stainless steel. The curvature of the inner side of the first bonding block 61 matches the curvature of the outer wall of the gas purification tube body 1. Thus, by rotating and turning the first bolt 62 on the outside, the first bonding block 61, together with the front end fixing suction cup 63, can be installed on the outside of the gas purification tube body 1. Two first bolts 62 are threaded to both ends of the first bonding block 61.
[0033] The ends of the two first bolts 62 are threaded to the outer wall of the gas purification pipe body 1. Multiple fixing suction cups 63 are fixedly installed on the outer wall of the first bonding block 61. The fixing suction cups 63 are made of silicone material and are designed with a bowl-shaped structure. When the installation position is a flat surface lacking a fixing object, the fixing suction cups 63 can be directly adsorbed onto the flat surface by air pressure difference. This provides a convenient installation structure when it is inconvenient to use the method of wrapping and fixing with straps when there is no fixing object.
[0034] The first bonding block 61 is made of stainless steel, and the curvature of the inner side of the first bonding block 61 matches the curvature of the outer wall of the gas purification tube body 1. Thus, by rotating and tightening the first bolt 62 on the outside, the first bonding block 61, along with the front-end fixing suction cup 63, can be installed on the outside of the gas purification tube body 1. The fixing suction cup 63 is made of silicone and is designed with a bowl-shaped structure. When the installation position is a flat surface lacking a fixing object, the fixing suction cup 63 can be directly adsorbed and fixed on the flat surface by the air pressure difference, which has a more convenient installation structure and improves the ease of installation and adaptability of the gas purification tube with convenient fixing mechanism.
[0035] Working principle:
[0036] When using a gas purification tube with a convenient fixing mechanism, screw the upper and lower ends of the gas purification tube into the middle of the hydrogen generator pipeline through the threaded head. Then, the gas flowing through the hydrogen generator pipeline will flow from the upper end to the lower end inside the gas purification tube. Inside the gas purification tube, it undergoes filtration, purification, and drying, which can ensure that the impurity content of the transported gas is reduced, and the water content is also reduced, effectively achieving the gas filtration effect.
[0037] The connection structure of the gas purification tube with a convenient fixing mechanism:
[0038] Two ventilation chambers 44 are respectively opened on the inner side of the upper end 3 and the lower end 2. The ventilation chambers 44 are used to transport and guide the gas entering the gas purification pipe body 1 into the pipe or lead it out to the through hole 43, which serves as a transition. The sealing gasket 41 is made of rubber material. The rubber sealing gasket 41 can improve the sealing effect at the pipe joint after the lower end 2 and the upper end 3 are connected to the external pipe. The hollow part inside the threaded head 42 is set as the through hole 43 for ventilation. The threaded head 42 can be rotated and screwed into the middle of the hydrogen generator pipe that needs to be purified.
[0039] The internal filling structure of the gas purification tube with a convenient fixing mechanism:
[0040] The extraction rack 52 is made of stainless steel and has a cylindrical frame structure formed by four metal strips welded together. The diameter of the extraction rack 52 is slightly smaller than the inner diameter of the gas purification tube 1. The splicing pipe 51 can be fixed by screwing the outer thread into the inner side of the end of the gas purification tube 1. The filter filler 53, made of activated carbon, can be manually inserted into the four-sided gaps inside one extraction rack 52. The filter filler 53 has a good filtration and adsorption function. The dry filler 55, made of silica gel particles, is inserted into the other extraction rack 52. It can absorb excess moisture inside the gas. When the filler needs to be removed for replacement, the upper end 3 and the lower end 2 can be twisted in the opposite direction to move the splicing pipe 51 away from both ends of the gas purification tube 1. Then, the extraction rack 52 on both sides can be pulled out through the splicing pipe 51. The extraction rack 52 can be removed together with the inner filler, which is convenient for replacement and does not require additional tools.
[0041] Planar adsorption fixing structure of gas purification tube with convenient fixing mechanism:
[0042] The first bonding block 61 is made of stainless steel, and the curvature of the inner side of the first bonding block 61 matches the curvature of the outer wall of the gas purification tube body 1. Thus, by rotating and tightening the first bolt 62 on the outside, the first bonding block 61, together with the front-end fixing suction cup 63, can be installed on the outside of the gas purification tube body 1. The fixing suction cup 63 is made of silicone and is designed with a bowl-shaped structure. When the installation position is a flat surface without a fixing object, the fixing suction cup 63 can be directly adsorbed and fixed on the flat surface by the air pressure difference.
[0043] Example 2:
[0044] Please see Figure 1-6 In this embodiment, a gas purification tube with a convenient fixing mechanism further includes a pipe clamp fixing structure 7, including a second fitting block 71 and a positioning hole 76. The second fitting block 71 is movably connected to the other side of the outer wall of the gas purification tube body 1. The second fitting block 71 is also made of stainless steel. The inner curvature of the second fitting block 71 conforms to the curved surface of the outer wall of the gas purification tube body 1. The second fitting block 71 can be fixed by tightening the second bolt 72. The two ends of the second fitting block 71 are threadedly connected to the second bolt 72. The ends of the two second bolts 72 are threadedly connected to the outer wall of the gas purification tube body 1. The inner side of the second fitting block 71 is rotatably connected to a rotating shaft 73.
[0045] The rotating shaft 73 allows the horizontally positioned movable clamp 74 to easily rotate along one side of the fixed clamp 75. Both the movable clamp 74 and the fixed clamp 75 have semi-circular arcs on their inner sides. When the movable clamp 74 is closed towards the fixed clamp 75, the inner sides of the two semi-circular arcs can clamp nearby pipes, connecting columns, or protrusions. When the front end of the movable clamp 74 is in contact with the positioning hole 76, the pipe can be tightened and fixed by screwing an external screw into the connection between the positioning hole 76 and the movable clamp 74. This is a backup fixing method, which improves the ease of installation of gas purification pipes with convenient fixing mechanisms. The movable clamp 74 is rotatably connected to the outer wall of the rotating shaft 73, and the fixed clamp 75 is fixedly installed on the outer wall of the second contact block 71. The positioning hole 76 is fixedly opened on the outer wall of the fixed clamp 75, and the end of the movable clamp 74 is movably connected to the positioning hole 76.
[0046] Working principle:
[0047] The second bonding block 71 is also made of stainless steel. The inner curvature of the second bonding block 71 matches the outer wall curvature of the gas purification pipe body 1. The second bonding block 71 can be fixed by tightening the second bolt 72.
[0048] The rotating shaft 73 allows the horizontally positioned movable clamp 74 to easily rotate along one side of the fixed clamp 75. Both the movable clamp 74 and the fixed clamp 75 have semi-circular arcs on their inner sides. When the movable clamp 74 is closed towards the fixed clamp 75, the inner sides of the two semi-circular arcs can clamp nearby pipes, connecting columns, or protrusions. When the front end of the movable clamp 74 is in contact with the positioning hole 76, the external screw can be screwed into the connection between the positioning hole 76 and the movable clamp 74 to tighten and fix the installed pipe. This is a backup fixing method, which improves the ease of installation of gas purification pipes with convenient fixing mechanisms.
