DETAILED DESCRIPTION

[0024] The preferred embodiments of the present invention are described below in conjunction with the accompanying drawings. It should be understood that the preferred embodiments described herein are only used to illustrate and explain the present invention, and are not used to limit the present invention.

[0025] Example 1

[0026] like Figure 1-5 As shown, the utility model proposes a pipe fastening device for an air compressor heat exchange mechanism, comprising a heat exchange mechanism shell 1, a connecting pipe 2 is fixedly connected to the side of the heat exchange mechanism shell 1, a rotating ring 3 is threadedly connected to the surface of the connecting pipe 2, a limiting column 4 is passed through the side of the rotating ring 3, a disc 5 is rotatably connected to the surface of the connecting pipe 2 located on the side of the limiting column 4, a limiting groove 6 is provided on the side of the disc 5, a transmission column 7 is fitted on the inner wall of the limiting groove 6, a fixed column 8 is fixedly connected to the side of the transmission column 7, an anti-slip sleeve 9 is provided on the bottom of the fixed column 8, and a limiting plate 10 is fixedly connected to the surface of the connecting pipe 2 located on the side of the disc 5.

[0027] Among them, there are six groups of limit posts 4 symmetrically arranged about the center of the rotating ring 3, and the sides of the six groups of limit posts 4 that are in contact with the disk 5 are all provided with silicone pads. When working, because the sides of the six groups of limit posts 4 that are in contact with the disk 5 are all provided with silicone pads, when the rotating ring 3 drives the limit posts 4 to completely rest against the disk 5, the silicone pads will increase the friction between the limit posts 4 and the disk 5, so that the limit posts 4 can better fix the disk 5.

[0028] Among them, there are three groups of limit grooves 6 symmetrically arranged about the center of the disk 5, and the three groups of limit grooves 6 are inclined. During operation, because the three groups of limit grooves 6 are inclined, when the disk 5 rotates counterclockwise, the three groups of limit grooves 6 will be driven to rotate together. Because the three groups of transmission columns 7 are respectively embedded in the three groups of limit grooves 6, when the three groups of limit grooves 6 rotate, thrust will be applied to the three groups of transmission columns 7, so that the three groups of transmission columns 7 are close to the center of the disk 5.

[0029] Among them, there are three groups of transmission columns 7 and three groups of fixed columns 8. During operation, when the three groups of transmission columns 7 move through the three groups of limit grooves 6, the three groups of fixed columns 8 fixedly connected to the three groups of transmission columns 7 will be driven to move toward the center of the disc 5.

[0030] Among them, three groups of anti-slip sleeves 9 are provided, and three groups of limiting plates 10 are provided. The three groups of fixing columns 8 respectively penetrate the tops of the three groups of limiting plates 10. During operation, because the three groups of fixing columns 8 respectively penetrate the tops of the three groups of limiting plates 10, when the three groups of fixing columns 8 move toward the center of the disc 5, the three groups of limiting plates 10 will play a certain limiting role on the three groups of fixing columns 8, and then the three groups of anti-slip sleeves 9 fixedly connected with the three groups of fixing columns 8 will move toward the center of the disc 5 together. When the anti-slip sleeves 9 move close to the connection between the pipeline and the connecting pipe 2, the connection between the pipeline and the connecting pipe 2 can be reinforced to prevent the pipeline from loosening.

[0031] Example 2

[0032] like Figure 1-5 As shown, the utility model proposes a pipe fastening device for an air compressor heat exchange mechanism. Compared with Example 1, as another implementation of the utility model, the bottom of the heat exchange mechanism shell 1 is fixedly connected with a mounting plate 11, the surface of the mounting plate 11 is attached to a bottom plate 12, the surface of the bottom plate 12 is rotatably connected with a threaded rod 13, the surface of the threaded rod 13 is meshed with a block 14, the side of the bottom plate 12 is threadedly connected with a screw 16, the surface of the screw 16 is meshed with a mounting bracket 15, and the side of the mounting bracket 15 is fixedly connected with a spring damper 17.

[0033] Among them, the surface of the threaded rod 13 is provided with two groups of threads in opposite directions, and the two groups of threaded surfaces of the threaded rod 13 are meshed with blocks 14. During operation, the staff can embed the heat exchange mechanism into the top groove of the bottom plate 12 through the heat exchange mechanism shell 1 and the mounting plate 11, and then rotate the threaded rod 13 clockwise. Because the surface of the threaded rod 13 is provided with two groups of threads in opposite directions, and the two groups of blocks 14 are respectively meshed with them, when the threaded rod 13 rotates, it will drive the two groups of blocks 14 to move closer to each other. When the two groups of blocks 14 slide along the top of the mounting plate 11 until they are completely against the heat exchange mechanism shell 1, the heat exchange mechanism shell 1 can be fixed.

[0034] During operation, when the heat exchange mechanism needs to be used, the pipeline can be first embedded into the connecting pipe 2, and then the disc 5 is rotated counterclockwise. Because three groups of inclined limiting grooves 6 are opened on the side of the disc 5, and the three groups of transmission columns 7 are respectively embedded in the three groups of limiting grooves 6, when the disc 5 rotates, the three groups of limiting grooves 6 will apply thrust to the three groups of transmission columns 7, so that the three groups of transmission columns 7 are brought closer to the center of the disc 5. Because the three groups of fixed columns 8 are respectively fixedly connected to the three groups of transmission columns 7, when the three groups of transmission columns 7 move, they will drive the three groups of fixed columns 8 to move closer to the center of the disc 5 under the limitation of the three groups of limiting plates 10. At this time, the three groups of anti-slip sleeves 9 will move towards the center of the disc 5 accordingly. When the three groups of fixing posts 8 and the anti-slip sleeve 9 are brought together to fit tightly with the connection between the connecting pipe 2 and the pipeline, the rotating ring 3 is twisted to make the rotating ring 3 move closer to the disc 5. At this time, the six groups of limiting posts 4 will move closer to the disc 5. When the six groups of limiting posts 4 are brought together to fit with the disc 5, the disc 5 can be fixed in the current position. The side of the limiting posts 4 that contacts the disc 5 is provided with a silicone pad to increase the friction force, so that the limiting posts 4 can better fix the disc 5 in the current position. When the disc 5 is fixed in the current position, the fixing posts 8 and the anti-slip sleeve 9 will stay in the current position. At this time, the purpose of fixing the connection between the connecting pipe 2 and the pipeline can be achieved to prevent the pipeline from loosening.

[0035] By setting the bottom plate 12, the staff can embed the heat exchange mechanism into the top groove of the bottom plate 12 through the heat exchange mechanism shell 1 and the mounting plate 11, and then rotate the threaded rod 13 clockwise. Because the surface of the threaded rod 13 is provided with two sets of threads in opposite directions, and the two sets of blocks 14 are respectively engaged with them, when the threaded rod 13 rotates, it will drive the two sets of blocks 14 to move closer to each other. When the two sets of blocks 14 slide along the top of the mounting plate 11 until they completely rest against the heat exchange mechanism shell 1, the heat exchange mechanism shell 1 can be fixed, and then the spring damper 17 is installed through the mounting frame 15 and the screws 16, so that the heat exchange mechanism can be damped when it is working.

[0036] Finally, it should be noted that the above description is only a preferred embodiment of the utility model and is not intended to limit the utility model. Although the utility model is described in detail with reference to the above embodiments, those skilled in the art can still modify the technical solutions recorded in the above embodiments or replace some of the technical features therein by equivalents. Any modification, equivalent replacement, improvement, etc. made within the spirit and principle of the utility model shall be included in the protection scope of the utility model.
