DETAILED DESCRIPTION

[0022] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0023] Reference Figure 1-3 The gas pipeline stable and safe connection device comprises a top plate 1, a shock-absorbing rubber pad 2 is fixedly installed on the bottom surface of the top plate 1, a plurality of telescopic rods 3 are fixedly installed on the bottom surface of the shock-absorbing rubber pad 2, a clamp 9 is commonly installed at the bottom end of each telescopic rod 3, and a second spring 18 is arranged inside each telescopic rod 3. The vibration received by the top plate 1 can be effectively eliminated through the cooperation of the second spring 18 and the shock-absorbing rubber pad 2, so as to provide shock-absorbing protection for the gas pipe installed on the base 19;

[0024] A reset shock-absorbing mechanism is provided between the shock-absorbing rubber pad 2 and the base 19, and the reset shock-absorbing mechanism includes a rotating seat 4, and a plurality of rotating seats 4 are symmetrically installed on the bottom surface of the shock-absorbing rubber pad 2 and the top surface of the base 19, respectively. A connecting rod 5 is rotatably connected in each rotating seat 4, and the other ends of the two connecting rods 5 corresponding to the position are provided with an assembly seat 6, and each connecting rod 5 is rotatably connected to the assembly seat 6 corresponding to the position, and a first spring 7 is installed between the two assembly seats 6. By pulling the first spring 7, it is prevented that when the second spring 18 is reset, the speed generated is too fast, thereby affecting the gas pipe;

[0025] A plurality of clamps 9 are provided on the bottom surface of the base 19, and an air bag 17 is bonded to the inner wall of each clamp 9. The air bag 17 can form a protective pad between the gas pipeline and the clamp 9, thereby reducing the impact force received by the gas pipeline. A plurality of air pumping mechanisms are provided between the shock-absorbing rubber pad 2 and the base 19, and each air pumping mechanism is connected to the air bag 17 at the corresponding position. The air pumping mechanism includes a sliding sleeve 8, and the sliding sleeve 8 is fixedly installed on the top surface of the base 19. A plurality of sliding rods 10 are symmetrically installed on the bottom surface of the shock-absorbing rubber pad 2, and a piston 11 is installed at the bottom end of each sliding rod 10, and each piston 11 is slidably connected in the sliding sleeve 8 at the corresponding position, and each sliding sleeve 8 is connected to the air bag 17 at the corresponding position. When the top plate 1 receives strong vibration, the top plate 1 and the base 19 are close to each other and separated by the second spring 18, thereby driving the piston 11 to slide repeatedly, inflate the air bag 17, and wrap the pipeline, thereby preventing the vibration of the strong vibration clamp 9 from causing damage to the outer wall of the pipeline;

[0026] Each sleeve 8 is connected to an air inlet pipe 13 and an air outlet pipe 14, and each sleeve 8 is connected to a pressure relief pipe 12. A pressure relief valve is installed in each pressure relief pipe 12. When the air bag 17 is inflated to the maximum value, the piston 11 moves downward to drive the pressure relief valve to lock, thereby discharging the air in the sleeve 8 to avoid affecting the shock absorption effect.

[0027] One-way valves are installed in the air inlet pipe 13 and the air outlet pipe 14, and each airbag 17 is connected to a connecting pipe 15, and the connecting pipe 15 passes through the clamp 9 and extends outward, and each connecting pipe 15 is connected to the outlet pipe 14 at the corresponding position. It is worth noting that through the setting of the one-way valve, the gas flow direction of the air inlet pipe 13 and the outlet pipe 14 is fixed, and the air inlet pipe 13 allows external air to enter the sliding sleeve 8, and the air is discharged into the airbag 17 through the outlet pipe 14, and each airbag 17 is connected to an exhaust pipe 16, and the exhaust pipe 16 passes through the clamp 9 and extends outward, and the diameter length of the exhaust pipe 16 is smaller than the diameter length of the connecting pipe 15, and the exhaust pipe 16 is used to prevent the airbag 17 from rupturing after being inflated to the limit.

[0028] When the utility model is used, the shock-absorbing rubber pad 2 and the bottom device are first fastened to the ground of the top plate 1 by expansion screws. When the top plate 1 vibrates, the vibration of the pipeline is reduced by the cooperation of the telescopic rod 3 and the second spring 18. At the same time, the vibration caused by the reset of the second spring 18 is further reduced by the cooperation of the connecting rod 5, the rotating seat 4 and the first spring 7, so as to avoid affecting the stable connection of the gas pipeline.

[0029] At the same time, when the top plate 1 vibrates strongly, the proximity of the shock-absorbing rubber pad 2 and the base 19 will drive the piston 11 to slide back and forth, and then the airbag 17 is inflated through the piston 11, and the space between the pipeline and the clamp 9 is filled through the airbag 17 to avoid strong vibration and damage to the outer wall of the pipeline caused by the clamp 9.

[0030] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
