[0022] In order to make the technical scheme and advantages of the utility model clearer, the utility model will be described in further detail below with reference to the drawings and examples. It should be understood that the specific examples described herein are only used to explain the utility model and not to limit the utility model.

[0023] The utility model provides a technical scheme: refer to Figure 1 Figure 5 The utility model discloses an air inlet and outlet pipe port self-adaptive type magnetic suspension blower, including device body 1, it has two interfaces 2,

[0024] Still include:

[0025] Two fixed rings 3 are fixed respectively and are set in the top of corresponding interface 2, and a plurality of rectangular holes 4 are formed on the fixed ring 3 oppositely, and the ring wall of the fixed ring 3 is provided with soft ring pipe 5;

[0026] A plurality of storage tanks 6 are oppositely formed on the inner wall of corresponding rectangular hole 4 and located on the outer circumferential side of soft ring pipe 5, and the inside of storage tank 6 is slidably provided with piston rod 7, and the bottom side of storage tank 6 is provided with adjusting mechanism 8, for adjusting the amount of filling liquid in storage tank 6 and soft ring pipe 5.

[0027] In the embodiment, the improved magnetic suspension blower is used, please refer to Figure 1 As shown in the drawing, with the operation of device body 1, external gas flows into device body 1 from one interface 2, and is discharged from another interface 2, (two interfaces 2 are respectively air inlet pipe port and air outlet pipe port)

[0028] Please refer to Figure 1 Figure 5 When connecting the air inlet and outlet pipe port with external pipeline, the operator sucks the filling liquid in soft ring pipe 5 and storage tank 6 through adjusting mechanism 8, with the reduction of filling liquid in soft ring pipe 5 and storage tank 6, piston rod 7 gradually shrinks into storage tank 6, then the pipeline is butt jointed on interface 2, then the bolt of corresponding specification is passed through rectangular hole 4 and is screwed into the corresponding threaded hole of the pipeline, finally the filling liquid is injected into storage tank 6 through adjusting mechanism 8, so that a plurality of piston rods 7 are inserted into rectangular hole 4, to form a corresponding hole on the outer circumferential side of the bolt, so as to complete the fixation of the pipeline and interface 2, the air inlet and outlet pipe port of the magnetic suspension blower can be self-adaptively changed to meet the connection requirements of the pipeline and the bolt used, so that the air inlet and outlet pipe port and the replaced pipeline can be well butt jointed;

[0029] ​​When the adjusting mechanism adjusts the structure to inject the filling liquid into the storage tank 6, a part of the filling liquid is injected into the soft ring pipe 5, so that the soft ring pipe 5 is deformed to form a surface completely adhering to the pipeline, and the sealing of the gap between the pipeline and the interface 2 is well completed, and the problem that the sealing ring is permanently deformed due to long-term extrusion to affect the sealing performance between the pipeline and the interface 2 does not occur.

[0030] In further preferable embodiments of the present application, as shown in Figure 2 and Figure 3 , the plurality of storage tanks 6 located on the same surface are arranged at equal intervals, and one end of the piston rod 7 close to the corresponding rectangular hole 4 is arranged in a hemispherical shape.

[0031] In the present embodiment, as shown in Figure 2 and Figure 3 , during the process that the piston rod 7 is inserted into the rectangular hole 4 and interferes with the bolt, the bolt is limited and positioned by the inclined direction of the outer peripheral wall of the bolt through the interference between the hemispherical surface of the piston rod 7 and the outer peripheral wall of the bolt, so that the limiting effect of the piston rod 7 on the bolt is enhanced.

[0032] In further preferable embodiments of the present application, as shown in Figure 1 , Figure 4 and Figure 5 , the bottom side of the soft ring pipe 5 is arranged in an open shape and is fixedly connected with the corresponding fixed ring 3, the inner and outer ring walls of the soft ring pipe 5 are slidably connected with the ring wall of the corresponding fixed ring 3, and the top side of the soft ring pipe 5 is coplanar with the top side of the corresponding fixed ring 3.

[0033] In the present embodiment, as shown in Figure 5 , the soft ring pipe 5 is arranged in the fixed ring 3, so that when the soft ring pipe 5 is contracted and deformed, it can be directly shrunk into the fixed ring 3, so as to prevent the soft ring pipe 5 from being damaged when the pipeline is connected with the interface 2.

[0034] In further preferable embodiments of the present application, as shown in Figure 1 - Figure 5 , the adjusting mechanism 8 comprises a liquid storage ring 81 fixedly arranged on the bottom side of the corresponding fixed ring 3 and fixedly connected with the corresponding interface 2, a shunt groove 82 is arranged at the position of the corresponding storage tank 6 in the fixed ring 3, the inside of the liquid storage ring 81 is connected with the inside of the soft ring pipe 5 and the inside of the corresponding storage tank 6 through a plurality of connecting holes and connecting pipes, and a piston ring plate 83 is slidably arranged in the liquid storage ring 81.

[0035] In the present embodiment, as shown in Figure 1 - Figure 5 , the adjusting mechanism 8 comprises a liquid storage ring 81 fixedly arranged on the bottom side of the corresponding fixed ring 3 and fixedly connected with the corresponding interface 2, a shunt groove 82 is arranged at the position of the corresponding storage tank 6 in the fixed ring 3, the inside of the liquid storage ring 81 is connected with the inside of the soft ring pipe 5 and the inside of the corresponding storage tank 6 through a plurality of connecting holes and connecting pipes, and a piston ring plate 83 is slidably arranged in the liquid storage ring 81.As shown, when the piston ring plate 83 moves up, the filling liquid in the liquid storage ring 81 can be pushed into the soft ring tube 5 from the connecting hole and into the distribution groove 82 from the connecting tube and then into the storage tank 6. When the piston ring plate 83 moves down, as the space in the liquid storage ring 81 expands, the filling liquid in the soft ring tube 5 and the storage tank 6 can be reabsorbed into the liquid storage ring 81 through the connecting hole, the connecting ring and the distribution groove 82, so that a negative pressure cavity is formed in the storage tank 6 and the soft ring tube 5, the piston rod 7 is sucked into the storage tank 6, and the soft ring tube 5 is deformed and shrunk, without the need for other operations, and the device is simple to operate.

[0036] In a further preferred embodiment of the utility model, as shown in Figure 4 As shown, the bottom side of the piston ring plate 83 is rotationally provided with a threaded tube 84, and the bottom of the threaded tube 84 is provided in a multi-ribbed tube shape and is threadedly connected with the interface 2.

[0037] In this embodiment, please refer to Figure 4 As shown, counterclockwise rotation of the threaded tube 84 can pull the piston ring plate 83 down, and clockwise rotation of the threaded tube 84 can push the piston ring plate 83 up, which is relatively simple to operate. The multiple edges formed on the outer circumferential wall of the bottom end of the threaded tube 84 enable the threaded tube 84 to be rotated with the aid of a wrench, which reduces the force exerted by the operator when rotating the threaded tube 84, and further reduces the working intensity of the operator.

[0038] Working principle: when the improved magnetic suspension blower is in use, with the operation of the device body 1, external gas flows into the device body 1 from the pipeline and one of the interfaces 2, and is discharged to the corresponding position from the other interface 2 and the pipeline;

[0039] When connecting the air inlet and outlet pipe openings with the external pipelines, the operator first reversely rotates the threaded tube 84 by the handle, and then pulls the piston ring plate 83 down. At this time, as the space in the liquid storage ring 81 expands, the filling liquid in the soft ring tube 5 and the storage tank 6 can be reabsorbed into the liquid storage ring 81 through the connecting hole, the connecting ring and the distribution groove 82, so that a negative pressure cavity is formed in the storage tank 6 and the soft ring tube 5, the piston rod 7 is sucked into the storage tank 6, and the soft ring tube 5 is deformed and shrunk into the fixed plate;

[0040] Then, the existing pipeline butt joint method is used to complete the butt joint of the pipeline and the interface 2. Subsequently, the bolts of the corresponding specifications are inserted through the rectangular holes 4 and screwed into the corresponding threaded holes in the pipeline. In this process, the bolts can be moved randomly in the rectangular holes 4 to adjust the position of the bolts so that they can be accurately inserted into the threaded holes on the pipeline.

[0041] After the bolt is installed, the operator is screwing the threaded tube 84, pushing the piston ring plate 83 to move upwards, so that part of the filling liquid in the liquid storage ring 81 is pushed into the soft ring tube 5 from the connecting hole, and is pushed into the shunt groove 82 from the connecting tube and then flows into the storage tank 6. Due to the pushing of the filling liquid to the wall of the soft ring tube 5, the soft ring tube 5 is deformed to form a surface that is completely fitted with the pipeline, which can well complete the sealing of the gap between the replaced pipeline and the interface 2. At the same time, due to the pushing of the filling liquid to the piston rod 7, the piston rod 7 is inserted into the rectangular hole 7 synchronously until the hemispherical end of the piston rod 7 is in contact with the bolt, thereby forming a corresponding hole on the outer circumferential side of the bolt, completing the constraint and positioning of the bolt, so that the position of the bolt in the fixed ring 3 remains stable without being subjected to a great external force, and the butt joint of the pipeline and the interface 2 is completed.

[0042] The basic principle, main features and advantages of the present application are shown and described above. It should be understood by those skilled in the art that the present application is not limited by the above embodiments, and the above embodiments and descriptions in the specification are only the principles of the present application. Without departing from the spirit and scope of the present application, various changes and improvements can be made to the present application, and these changes and improvements all fall within the scope of the claimed present application.
