However, there are still the following deficiencies such as:

[0003] After completion, the above equipment is easy to install. However, when in use, a large amount of gas at the front end will impact the inside of the pipeline when the gas is used, which may easily cause internal rupture of the pipeline and gas leakage. At the same time, when a large amount of gas begins to be used and discharged, the pipeline will vibrate and easily shake off the direct connection points between the pipelines. Therefore, we proposed a gas pipeline protection device. Utility Model Content

[0004] The utility model aims to provide a gas pipeline protection device, which solves the problem that a large amount of gas at the front end of the existing equipment will impact the inside of the pipeline when the gas is used, which may easily cause the inside of the pipeline to rupture and gas leakage. At the same time, when a large amount of gas starts to be used and discharged, the pipeline will vibrate and the direct connection points between the pipelines will be easily shaken off.

[0005] In order to solve the above technical problems, the utility model is realized by the following technical solutions:

[0006] The utility model discloses a gas pipeline protection device, comprising a gas pipe, wherein the outer wall of the gas pipe is fixedly connected with a plurality of flanges, the outer wall of the gas pipe is provided with a plurality of outer protection pipes, a plurality of plug-in arc plates are fixedly connected with a central axis of the outer wall of the outer protection pipe, a plurality of fixing grooves are provided on the inner wall of the plug-in arc plates, a plurality of outer protection pipes II are provided on the outer wall of one end of the gas pipe away from the outer protection pipe, and a plurality of fixing cavities are provided on the inner wall of the outer protection pipe II.

[0007] Furthermore, an inner wall of the fixed cavity is fixedly connected with a compression spring, an outer wall of one end of the compression spring away from the fixed cavity is fixedly connected with a fixed support rod, and the fixed support rod passes through the outer protective pipe to the inner wall.

[0008] Furthermore, the inner wall of the second outer protective pipe is provided with a plurality of installation cavities, the installation cavities are fitted with the plug-in arc plates, and the outer wall of one end of the fixed support rod away from the gas pipe is fixedly connected with a pulling plate.

[0009] Furthermore, the pulling plate extends to the outer wall of the second outer protective pipe, and a pressure spring is fixedly connected to the outer wall of the pulling plate on a side away from the flange.

[0010] Furthermore, a fixed vertical plate is fixedly connected to an outer wall of a side of the pressure spring away from the pulling plate, and the fixed vertical plate is fixedly connected to the second outer protective pipe.

[0011] Furthermore, the outer walls of the plurality of outer protective pipes and the second outer protective pipe on one side close to the gas pipe are fixedly connected with a plurality of buffer rebound plates, and the buffer rebound plates are fixedly connected to the gas pipe.

[0012] Furthermore, a plurality of built-in rubber plates are fixedly connected to the inner wall of the gas pipe, and a built-in rubber frame is slidably connected to the inner wall of one end of the built-in rubber plate close to the gas pipe.

[0013] Furthermore, a plurality of buffer springs are fixedly connected to the outer wall of the built-in rubber frame away from the flange, and a second built-in rubber frame is slidably connected to the outer wall of one end of the buffer spring away from the built-in rubber frame. An air outlet cavity is provided at the central axis of the inner wall of the built-in rubber frame and the second built-in rubber frame.

[0014] The utility model has the following beneficial effects:

[0015] 1. The utility model sets a built-in rubber frame in the built-in rubber plate. When the equipment needs to be used, multiple built-in rubber frames and built-in rubber frame 2 are inserted into the inside of the gas pipe, so that the large-diameter openings of the built-in rubber frame and the built-in rubber frame 2 are completely against the inner wall of the built-in rubber plate, and then the flange is connected to the pipeline. When the equipment starts to be used, the gas will first pass through the built-in rubber frame. When passing through the built-in rubber frame, the gas will first be converted from the large opening to the small opening and then discharged into the built-in rubber frame 2, so that the large diameter can be converted to the small diameter, and then the small diameter can be converted to the large diameter, thereby reducing the impact force of the gas on the front end of the gas pipe, preventing a large amount of gas from impacting the gas pipe and causing the gas pipe to break. At the same time, the gas can be discharged normally to the gas outlet to prevent the situation of insufficient gas supply due to compressed gas.

[0016] 2. The utility model is provided with a buffer rebound plate on the gas pipe. When the equipment is in use, when the gas pipe causes internal expansion and vibration due to the discharge of a large amount of gas, the buffer rebound plate will begin to be slowly squeezed and rebound at the same time, which will reduce the vibration force of the gas pipe. At the same time, when installing the outer protection pipe and the fixed groove, it is only necessary to insert the plug-in arc plate into the installation cavity to support multiple fixed support rods so that the extrusion spring is squeezed, and then after being inserted to a certain extent, the extrusion spring rebounds to push the fixed support rod into the fixed groove, and the plug-in arc plate is clamped, so that the vibration force on the gas pipe can be reduced. At the same time, it is convenient for personnel to assemble the outer protection pipe and the fixed groove, which is convenient for subsequent maintenance and replacement.

[0017] Of course, any product implementing the present invention does not necessarily need to achieve all of the advantages described above at the same time. BRIEF DESCRIPTION OF THE DRAWINGS
