[0030] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0031] Reference Figure 1 - Figure 3The utility model provides an embodiment: an indoor gas pipeline pressure connection device, comprising a sealed cabinet 3, a main pipe 1 is installed through the left wall of the sealed cabinet 3, a sub-pipe 2 is installed through the right wall of the sealed cabinet 3, one end of the main pipe 1 is fixedly connected to a connecting plate 2 13, one end of the sub-pipe 2 is fixedly connected to a connecting plate 12, a plurality of screws 15 are arranged inside the connecting plate 2 13, a nut 14 is threadedly connected to the outer side of the screw 15, a plurality of fixing components are arranged on one side of the connecting plate 12, and the fixing components are used to fix the nut 14, a detection shell 6 is fixedly connected to the top of the sealed cabinet 3, a push plate 11 is slidably connected inside the detection shell 6, a connecting rod 10 is fixedly connected to the top of the push plate 11, a connecting plate 7 is fixedly connected to the top of the connecting rod 10, an alarm light 8 is arranged on the middle side of the top of the connecting plate 7, a plurality of metal sheets 9 are arranged at the bottom of the connecting plate 7, and a plurality of metal grooves 17 are opened on the upper side of the detection shell 6.

[0032] Specifically, during installation, first ensure that all parts are in a clean and dry state. Open the sealing door 4 so that the connecting plate 2 13 and the nut 14 between the auxiliary pipe 2 and the main pipe 1 can contact smoothly. In order to stabilize the connection, a special fixing assembly is used to accurately position and lock the nut 14, which can effectively prevent the risk of gas leakage caused by the loosening of the nut 14 in daily use. When a gas system leaks, the pressure generated by the leak will act on the push plate 11. As the push plate 11 moves upward, the connecting rod 10 also moves in conjunction, causing the connecting plate 7 and the alarm light 8 to rise. In this process, the metal sheet 9 is separated from the metal groove 17 due to the gas pressure. It is worth noting that the metal sheet 9 and the alarm light 8 are electrically connected, so when the metal sheet 9 falls off, the alarm light 8 will not light up due to the circuit interruption, which clearly indicates the gas leakage and reminds the user to take immediate measures for maintenance to ensure the safe operation of the gas system.

[0033] Reference Figure 2 and Figure 4 The fixed component includes a thin shell 18, one side of the thin shell 18 is fixedly connected to one side of the connecting plate 12, a pull rope 22 is slidably connected inside the thin shell 18, one end of the pull rope 22 is fixedly connected to the ring 16, and the other end of the pull rope 22 is fixedly connected to the baffle 19, a spring 20 is sleeved on the outside of the pull rope 22, and a plug-in block 21 is fixedly connected to one side of the baffle 19.

[0034] Specifically, when precise positioning or limit control of the nut 14 is required, the operator needs to cancel the previous disassembly steps. At this time, just gently release the handle previously used for disassembly. As the handle is released, the energy stored in the spring 20 begins to be released, which drives the baffle 19 to slide backward along a predetermined path. This action chain affects the plug-in block 21, causing it to follow the movement of the baffle 19 and re-embed accurately into the interior of the nut 14. In this way, the plug-in block 21 plays a limiting role to prevent the nut 14 from accidentally loosening during use. This design ensures the stability and safety of the gas system and avoids gas leakage caused by loosening of the nut 14.

[0035] Reference Figure 1 - Figure 4 The outer side of the connecting rod 10 is slidably connected to the inside of the detection shell 6, the metal sheet 9 is electrically connected to the alarm light 8, the outer side of the metal sheet 9 is slidably connected to the inside of the metal groove 17, a push plate 11 is provided on the top of the sealed cabinet 3, a sealed door 4 is installed on the front surface of the sealed cabinet 3, a handle 5 is fixedly connected to one side of the sealed door 4, the outer side of the baffle 19 is slidably connected to the inner wall of the thin shell 18, one end of the spring 20 is fixedly connected to one side of the baffle 19, the other end of the spring 20 is fixedly connected to the inner wall of the thin shell 18, the plug-in block 21 is plugged into the inside of the nut 14, and the outer side of the ring 16 is rotatably connected to the outside of the auxiliary pipe 2.

[0036] Specifically, the design of the connecting rod 10 allows it to slide freely inside the detection shell 6, so that the connecting rod 10 can push the connecting plate 7 to move. The metal sheet 9, as a key electrical component, forms an electrical connection with the alarm light 8. When the position of the metal sheet 9 changes, such as gas leakage, the alarm light 8 will respond and warn the user in time. The metal sheet 9 is also connected to the metal groove 17 in a sliding manner. Such a design enables the metal sheet 9 to effectively trigger the alarm mechanism during the sliding process. A push plate 11 is installed on the top of the sealed cabinet 3 to cope with the pressure changes inside the sealed door 4, while the sealed door 4 can ensure the sealing inside the cabinet and is equipped with a handle 5 for easy opening and closing. The baffle 19 is embedded in the thin shell 18 and controlled by the spring 20. The tension of the spring 20 helps to keep the position of the baffle 19 stable. The plug-in block 21 is cleverly inserted into the nut 14 to play a role in fixing and connecting. When the ring 16 rotates outside the auxiliary pipe 2, the pull rope 22 can be pulled to move, thereby pulling the baffle 19 to slide inside the thin shell 18. At this time, the spring 20 is compressed, and the movement of the baffle 19 controls the movement of the plug-in block 21.

[0037] Working principle: When disassembly inspection is required, the handle on the ring 16 is rotated to pull the pull rope 22 to move, and then the baffle 19 is pulled to slide inside the thin shell 18. At this time, the spring 20 is compressed, and the movement of the baffle 19 drives the plug-in block 21 to move until the plug-in block 21 leaves the inside of the nut 14. At this time, the nut 14 is rotated by a tool to disengage the screw 15. At this time, the connecting plate 12 and the nut 14 can be disassembled, and the secondary pipe 2 and the main pipe 1 are disassembled. When installation is required, the sealing door 4 is opened to remove the connecting plate 2 13 and the nut 1 between the secondary pipe 2 and the main pipe 1. 4 for flange connection, then release the handle, under the action of the spring 20, push the baffle 19 to move, and then drive the plug block 21 to re-enter the nut 14, then the installation is completed, to prevent the nut 14 from loosening during use and causing gas leakage. When the gas leaks, at this time, under the action of the gas pressure, the push plate 11 is pushed upward, and then the connecting rod 10 is pushed to move, so that the connecting plate 7 and the alarm light 8 also move upward, and at the same time the metal sheet 9 is separated from the metal groove 17. Since the metal sheet 9 and the alarm light 8 are electrically connected, the alarm light 8 is not on at this time, indicating a gas leak.

[0038] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent substitutions for some of the technical features therein.
