Description

Technical Field

[0001] The invention relates to the technical field of pipeline sealing connection, and specifically provides an insulating sealing connection component and a live device comprising the insulating sealing connection component. Background Art

[0002] Currently, the sealing joints for connecting the insulating hose and the live device mostly adopt threaded connection or more complex ferrule connection.

[0003] However, for threaded sealing joints, the threaded connection structure achieves clamping of the inner and outer metal pipes through the engagement between the inner and outer threads, thereby fixing the insulating hose to the metal inner pipe, achieving a sealing connection and preventing it from falling off. However, rapid disassembly and assembly cannot be achieved under limited space, and it is only suitable for areas with relatively large installation space. In addition, this type of sealing joint has many parts and components, and the installation steps are cumbersome. There is a risk of parts falling during the installation process, resulting in inconvenient installation.

[0004] Although the ferrule connection method can be used for installation in limited spaces and has a wider range of applications, its structure is more complex and the installation process is more cumbersome. It is necessary to first bind the insulating hose to one end of the metal pipe joint with a metal clamp, and then use the ferrule to dock the metal pipe joints. Additional sealing gaskets need to be added to the docking position, and finally the ferrule is tightened with bolts to achieve the sealing of the docking joint.

[0005] In the prior art, the existing sealed connection joints cannot be used for rapid disassembly and assembly in a limited space, and there is a risk of parts falling during the installation process. Therefore, there is an urgent need to develop a sealed connection joint with a simpler structure and easier disassembly and assembly. Summary of the invention

[0010] In the preferred technical solution of the above-mentioned insulating sealing connection assembly, the clamping component also includes an elastic member, which is arranged between the locking bolt and the clamping member, and the elastic member can apply a force parallel to the central axis of the locking bolt to the locking bolt to prevent the locking bolt from falling out of the bolt hole; and / or, a protective structure is also provided on the clamping member, which is arranged between two adjacent side surfaces on the clamping member and can prevent the clamping member from discharging.

[0011] In the preferred technical solution of the above-mentioned insulating sealing connection assembly, the metal outer tube is provided with a first mounting structure, and the engaging member is provided with a second mounting structure, and the first mounting structure cooperates with the second mounting structure to install the engaging member on the metal outer tube; and / or, a first clamping structure is provided on the outer wall of the first tube body, and a second clamping structure adapted to the first clamping structure is provided on the inner wall of the second tube body, and when installed, the first clamping structure and the second clamping structure cooperate to clamp the insulating hose between the first tube body and the second tube body.

[0012] In the preferred technical solution of the above-mentioned insulating sealing connection assembly, a side ear is provided on the metal outer tube, the first mounting structure is a mounting groove formed on the side ear, and the second mounting structure is a mounting column symmetrically arranged on the engaging member.

[0016] In a second aspect, the present invention provides a live device, comprising the insulating sealing connection assembly described in any one of the above items.

[0017] When the above-mentioned preferred technical solution is adopted, the second fixing part can be clamped on the first fixing part by the clamping component, so that the insulating hose can be clamped between the metal inner tube and the metal outer tube to achieve quick installation and disassembly. Compared with the insulating sealing connection assembly using threaded connection in the prior art, there is no need to use threaded connection, and the assembly is more convenient. Since there are fewer parts, the risk of parts falling during installation is lower. At the same time, quick disassembly and assembly can be achieved in a limited space. Compared with the ferrule connection method used in the prior art, the structure is simpler and the disassembly and assembly are more convenient, which greatly improves the assembly efficiency of the insulating sealing connection assembly.

[0018] Furthermore, by configuring the clamping component to include a clamping part and a locking part, on the one hand, the movement of the first boss can be limited by the clamping part, and the second boss can be driven to move toward the first boss by the locking part, so that the inner wall of the second tube body and the outer wall of the first tube body are squeezed against each other to clamp the insulating hose between the first tube body and the second tube body. This can not only overcome the friction between the insulating hose and the first tube body and the second tube body, making assembly more labor-saving, but also improve the sealing between the insulating hose and the first tube body. On the other hand, by configuring a guide structure on the clamping component, the second boss can be moved along the guide structure toward the first boss, so that the second boss can be prevented from rotating during the movement, making assembly smoother.

[0019] Furthermore, by providing a guide groove, the first boss and the second boss can be limited circumferentially to avoid circumferential rotation of the first boss and the second boss during assembly. By arranging the locking member to drive the second boss to move along the guide groove toward or away from the first boss, the second boss can be conveniently clamped on the first boss, or the second boss can be loosened from the first boss, thereby facilitating the installation and disassembly of the insulating sealing connection assembly of the clamping member. Compared with arranging the guide structure as a guide rod, arranging the guide structure as a guide groove can make the structure of the insulating sealing connection assembly simpler and have fewer parts.

[0020] Furthermore, by setting the locking piece as a locking bolt, the locking bolt can cooperate with the bolt hole on the locking piece, which can not only drive the second boss to move toward the first boss, but also clamp the second boss on the first boss, further simplifying the structure of the insulating sealing connection assembly and improving the assembly efficiency of the insulating sealing connection assembly.

[0021] Furthermore, by arranging an elastic member, the elastic member can be elastically deformed and apply a force parallel to the central axis of the locking bolt to the locking bolt, thereby creating a greater friction between the locking bolt and the bolt hole, thereby preventing the locking bolt from falling out of the bolt hole, and effectively preventing the live device from loosening and failing during operation.

[0022] Furthermore, by providing a protective structure between two adjacent side surfaces of the engaging member, the discharge effect caused by the sharp corners of the outer shape can be reduced, thereby improving the safety of the insulating sealing connection assembly.

[0023] Furthermore, by providing a first mounting structure and a second mounting structure, it is possible to facilitate the installation of the snap-fitting part on the metal outer tube, thereby realizing the pre-installation of the snap-fitting part and further improving the assembly efficiency of the insulating sealing connection assembly; by providing a first clamping structure and a second clamping structure, the friction between the insulating hose and the metal inner tube and the metal outer tube can be increased, so that the insulating hose can be clamped between the metal inner tube and the metal outer tube more stably, further improving the sealing effect of the insulating sealing connection assembly.

[0024] Furthermore, by configuring the first mounting structure as mounting grooves formed on both sides of the side ears and configuring the second mounting structure as mounting columns, on the one hand, the mounting columns can cooperate with the mounting grooves to pre-install the engaging parts on the metal outer tube, thereby improving assembly efficiency; on the other hand, the engaging parts can be rotated relative to the side ears with the mounting columns as axes. During assembly, the engaging parts can be rotated relative to the side ears so that the engaging parts are buckled against the bottom of the first boss, thereby facilitating the opening and closing of the engaging parts and further improving the convenience of assembly.

[0025] Furthermore, by providing a shielding cover, the anti-corona effect of the insulating sealing connection assembly can be achieved, thereby avoiding damage to structures such as the insulating hose due to discharge of the insulating sealing connection assembly, and further improving the safety of use of the insulating sealing connection assembly. Furthermore, by providing a limiting structure, the metal outer tube can be prevented from passing through the shielding cover, thereby preventing tip discharge.

[0026] In addition, the live device further provided by the present invention on the basis of the above-mentioned insulating sealing connection assembly has the beneficial effects of the above-mentioned insulating sealing connection assembly due to the inclusion of the above-mentioned insulating sealing connection assembly. Compared with the live device before improvement, the live device of the present invention has higher safety in use, better sealing of the pipe joint, and higher disassembly and assembly efficiency of the insulating sealing connection assembly.

For those skilled in the art, the specific meanings of the above terms in the present invention can be understood according to specific circumstances.

[0038] Specifically, see Figure 1 , Figure 1 It is a schematic structural diagram of the insulating sealing connection assembly of the present invention.

[0039] like Figure 1 As shown, the insulating sealing connection assembly of the present invention includes an insulating hose 5, a metal inner tube 1, a metal outer tube 2 and a clamping component 3. The insulating hose 5 is made of an insulating material. The metal inner tube 1 is connected to the live device. The metal inner tube 1 is adapted to the inner wall of the insulating hose 5 so that the insulating hose 5 can be sleeved on the outside of the metal inner tube 1. The metal outer tube 2 is adapted to the outer wall of the insulating hose 5 so that the metal outer tube 2 is sleeved on the outside of the insulating hose 5.

[0040] Among them, a first fixing part is provided on the metal inner tube 1, and a second fixing part adapted to the first fixing part is provided on the metal outer tube 2. The clamping component 3 is configured to clamp the second fixing part on the first fixing part to clamp the insulating hose 5 between the metal inner tube 1 and the metal outer tube 2.

[0041] When installed, the live device is insulated from other devices via the insulating hose 5 .

[0042] Through such a configuration, the second fixing part can be clamped on the first fixing part through the clamping member 3, so that the insulating hose 5 can be clamped between the metal inner tube 1 and the metal outer tube 2, thereby realizing quick installation and disassembly. Compared with the insulating sealing connection assembly using threaded connection in the prior art, there is no need to use threaded connection, and assembly is more convenient. Since there are fewer parts, the risk of parts falling during installation is lower. At the same time, quick disassembly and assembly can be achieved in a limited space. Compared with the ferrule connection method used in the prior art, the structure is simpler and disassembly and assembly are more convenient, which greatly improves the assembly efficiency of the insulating sealing connection assembly.

[0043] It should be noted that the present invention does not impose any limitation on the specific shape of the metal inner tube 1. For example, the inner cross-section of the insulating hose 5 can be set to be circular, and accordingly, the outer cross-section of the metal inner tube 1 is also circular, or the inner cross-section of the insulating hose 5 can be set to be square, and accordingly, the outer cross-section of the metal inner tube 1 is also square, or the insulating hose 5 can be set to any other possible form, as long as the metal inner tube 1 is compatible with the inner wall of the insulating hose 5, etc. Such adjustments and changes to the specific shape of the metal inner tube 1 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0044] Preferably, if Figure 1 As shown, the inner cross section of the insulating hose 5 is set to be circular, and the outer cross section of the metal inner tube 1 is also circular.

[0045] It should be noted that the present invention does not impose any limitation on the specific shape of the metal outer tube 2. For example, the outer cross-section of the insulating hose 5 can be set to be circular, and accordingly, the inner cross-section of the metal outer tube 2 is also circular, or the outer cross-section of the insulating hose 5 can be set to be square, and accordingly, the inner cross-section of the metal outer tube 2 is also square, or the metal outer tube 2 can be set to any other possible shape, as long as the metal outer tube 2 is compatible with the outer cross-section of the insulating hose 5, etc. Such adjustments and changes to the specific shape of the metal outer tube 2 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0046] Preferably, if Figure 1 As shown, the outer cross-section of the insulating hose 5 is circular, and the inner cross-section of the metal outer tube 2 is also circular.

[0047] It should be noted that, in actual applications, those skilled in the art may set the first fixing portion to be the first boss 12, and the second fixing portion to be the second boss 22, and when installed, the second boss 22 can be clamped on the first boss 12, or, the first fixing portion may be set to be the first connecting ear, and the second fixing portion may be set to be the connecting ear, and when installed, the second connecting ear can be clamped on the first connecting ear, or, the first fixing portion and the second fixing portion may be set to any other possible form, and so on. Such adjustments and changes to the specific setting types of the first fixing portion and the second fixing portion do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0048] Continue reading Figure 1 , and then see Figures 2 to 4 , Figure 2 It is a schematic structural diagram of the metal inner tube of the present invention; Figure 3 It is a schematic structural diagram of the metal outer tube of the present invention; Figure 4 It is a structural schematic diagram of the engaging member of the present invention.

[0049] Preferably, if Figures 1 to 3 As shown, the metal inner tube 1 includes a first tube body 11 and a first boss 12 arranged on the first tube body 11, and the metal outer tube 2 includes a second tube body 21 and a second boss 22 arranged on the second tube body 21. The first boss 12 forms a first fixing portion, and the second boss 22 forms a second fixing portion.

[0050] like Figure 1 and Figure 4As shown, the clamping member 3 includes a clamping member 31 and a locking member 32. The clamping member 31 can limit the movement of the first boss 12. The clamping member 31 also has a guide structure. The locking member 32 is configured to drive the second boss 22 to move along the guide structure toward the direction close to the first boss 12 so as to clamp the second boss 22 on the first boss 12. When installed, the insulating hose 5 is clamped between the first tube body 11 and the second tube body 21.

[0051] By configuring the clamping member 3 to include a clamping member 31 and a locking member 32, on the one hand, the movement of the first boss 12 can be limited by means of the clamping member 31, and the second boss 22 can be driven to move toward the direction of the first boss 12 by means of the locking member 32, so that the inner wall of the second tube body 21 and the outer wall of the first tube body 11 are squeezed against each other, so as to clamp the insulating hose 5 between the first tube body 11 and the second tube body 21. This can not only overcome the friction between the insulating hose 5 and the first tube body 11 and the second tube body 21, making assembly more labor-saving, but also improve the sealing between the insulating hose 5 and the first tube body 11. On the other hand, by configuring a guide structure on the clamping member 31, the second boss 22 can be moved along the guide structure toward the direction of the first boss 12, so as to prevent the second boss 22 from rotating during the movement, so as to make assembly smoother.

[0052] It should be noted that the first boss 12 can be configured to be integrally formed with the first tube body 11, or the first boss 12 can be configured to be snap-connected to the first tube body 11, or the first boss 12 can be configured to be fixedly connected to the first tube body 11 by fasteners, etc. Such adjustments and changes to the specific connection method between the first boss 12 and the first tube body 11 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0053] Exemplarily, the first boss 12 and the first tube body 11 are integrally formed.

[0054] It should be noted that the second boss 22 can be arranged to be integrally formed with the second tube body 21, or the second boss 22 can be arranged to be connected to the second tube body 21 by snapping, or the second boss 22 can be arranged to be fixedly connected to the second tube body 21 by fasteners, etc. Such adjustments and changes to the specific connection method between the second boss 22 and the second tube body 21 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0055] Exemplarily, the second boss 22 and the second tube body 21 are integrally formed.

[0056] It should be noted that, in actual applications, those skilled in the art may configure the guide structure to be a guide groove 311, and the first boss 12 and the second boss 22 may slide along the guide groove 311 to move the second boss 22 toward the first boss 12; or, the guide structure may be configured to be a guide rod, and the first boss 12 and the second boss 22 may slide along the guide rod to move the second boss 22 toward the first boss 12; or, the guide structure may be configured to be a combination of the guide groove 311 and the guide rod, and so on. Such adjustments and changes to the specific structural form of the guide structure do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0057] Preferably, if Figures 1 to 4 As shown, the guide structure is a guide groove 311 formed in the locking member 31. When installed, the first boss 12 is located in the guide groove 311 and abuts against the inner wall of the guide groove 311, the second boss 22 is located in the guide groove 311 and can move along the guide groove 311, and the locking member 32 is drivingly connected to the second boss 22 and can drive the second boss 22 to move along the guide groove 311 toward or away from the first boss 12.

[0058] By setting the guide groove 311, the first boss 12 and the second boss 22 can be limited circumferentially to avoid circumferential rotation of the first boss 12 and the second boss 22 during assembly; by setting the locking member 32 to be able to drive the second boss 22 to move along the guide groove 311 toward or away from the first boss 12, the second boss 22 can be conveniently clamped on the first boss 12, or the second boss 22 can be loosened from the first boss 12, thereby facilitating the installation and disassembly of the insulating sealing connection assembly of the clamping member 3; and compared with setting the guide structure in the form of a guide rod, setting the guide structure in the guide groove 311 can make the structure of the insulating sealing connection assembly simpler and have fewer parts.

[0059] The locking member 32 may be configured as a locking bolt, and a bolt hole 314 adapted to the locking bolt is provided on the engaging member 31, and the locking bolt can pass through the bolt hole 314 and be rotatably connected to the second boss 22, and the locking bolt cooperates with the bolt hole 314 to drive the second boss 22 to move toward the first boss 12 and clamp the second boss 22 on the first boss 12. Alternatively, the locking member 32 may be configured as a clamping rod, and a first clamping structure is provided on the first boss 12, and a second clamping structure is provided on the second boss 22, and the clamping rod abuts against the second boss 22. When the operator presses toward the direction of the first boss 12, the second clamping structure can be clamped on the first clamping structure, thereby clamping the second boss 22 on the first boss 12. Alternatively, the locking member 32 may be configured as any other possible form, and so on. Such adjustment and change to the specific setting type of the locking member 32 does not deviate from the protection scope of the present invention.

[0060] Preferably, if Figure 1 and Figure 4 As shown, the locking member 32 is a locking bolt, and a bolt hole 314 adapted to the locking bolt is provided on the clamping member 31. The locking bolt can pass through the bolt hole 314 and be rotatably connected to the second boss 22. The locking bolt can rotate relative to the second boss 22 to drive the second boss 22 to move toward or away from the first boss 12 and clamp the second boss 22 on the first boss 12.

[0061] By setting the locking piece 32 as a locking bolt, the locking bolt can cooperate with the bolt hole 314 on the locking piece 31, which can not only drive the second boss 22 to move toward the first boss 12, but also clamp the second boss 22 on the first boss 12, further simplifying the structure of the insulating sealing connection assembly and improving the assembly efficiency of the insulating sealing connection assembly.

[0062] It should be noted that, in actual applications, the present invention does not impose any limitation on the specific connection method for the rotational connection between the locking bolt and the second boss 22. For example, a bearing may be provided on the second boss 22 to enable the locking bolt to be rotationally connected to the second boss 22. Alternatively, a limiting hole 221 compatible with the locking bolt may be provided on the second boss 22, and the locking bolt is located in the limiting hole 221 and can rotate relative to the second boss 22, etc. Such flexible adjustments and changes do not deviate from the principle and scope of the present invention and should be included in the protection scope of the present invention.

[0063] Preferably, if Figure 3 As shown, a limiting hole 221 matched with the locking bolt is provided on the second boss 22 . During assembly, the locking bolt is located in the limiting hole 221 and can rotate relative to the second boss 22 .

[0064] With such a configuration, when the locking member 32 drives the second boss 22 to move toward the first boss 12, the locking bolt can cooperate with the limiting hole 221, thereby limiting the radial movement of the locking bolt, thereby preventing the locking bolt from being misaligned or skewed.

[0065] Preferably, if Figure 1 As shown, the clamping member 3 also includes an elastic member 33, which is arranged between the locking bolt and the clamping member 31. The elastic member 33 can apply a force parallel to the central axis of the locking bolt to the locking bolt to prevent the locking bolt from coming out of the bolt hole 314.

[0066] By setting the elastic member 33, the elastic member 33 can be elastically deformed and apply a force parallel to the central axis of the locking bolt to the locking bolt, so that there is a greater friction between the locking bolt and the bolt hole 314, thereby preventing the locking bolt from falling out of the bolt hole 314, and effectively preventing the live device from loosening and failing during operation.

[0067] It should be noted that the present invention does not impose any limitation on the specific setting type of the elastic member 33, as long as it can undergo elastic deformation and apply elastic force to the locking bolt. For example, the elastic member 33 can be set as a spring, or the elastic member 33 can be set as an elastic sheet, or the elastic member 33 can be set as an elastic sheet and a gasket 331, etc. Such adjustments and changes to the specific setting type of the elastic member 33 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0068] Preferably, if Figure 1 As shown, the elastic member 33 includes a gasket 331 and an elastic sheet 332 .

[0069] Preferably, a first mounting structure is provided on the metal outer tube 2 , and a second mounting structure is provided on the engaging member 31 . The first mounting structure cooperates with the second mounting structure to mount the engaging member 31 on the metal outer tube 2 .

[0070] By such a configuration, that is, by configuring the first mounting structure and the second mounting structure, it is possible to facilitate the installation of the engaging member 31 onto the metal outer tube 2, thereby achieving pre-installation of the engaging member 31 and further improving the assembly efficiency of the insulating sealing connection assembly.

[0071] Preferably, if Figure 1 and Figure 3As shown, the metal outer tube 2 is provided with side ears 213, the first mounting structure is a mounting groove 212 formed on both sides of the side ears 213, and the second mounting structure is a mounting column 312 symmetrically arranged on the engaging member 31. When installed, the two mounting columns 312 are respectively located in the two mounting grooves 212, and the engaging member 31 can also rotate relative to the side ears 213 with the mounting column 312 as the axis.

[0072] Through such a configuration, on the one hand, the mounting column 312 can cooperate with the mounting groove 212 to pre-install the engaging member 31 on the metal outer tube 2, thereby improving the assembly efficiency. On the other hand, the engaging member 31 can be rotated relative to the side ear 213 with the mounting column 312 as the axis. During assembly, the engaging member 31 can be rotated relative to the side ear 213 so that the engaging member 31 is buckled to the bottom of the first boss 12, thereby facilitating the opening and closing of the engaging member 31 and further improving the convenience of assembly.

[0079] Through such an arrangement, the first boss 12 and the second boss 22 can be clamped at multiple locations through the clamping member 3. On the one hand, it can avoid that there are too few clamping locations resulting in loose clamping of the metal inner tube 1 and the metal outer tube 2. On the other hand, it can also avoid that the first boss 12 and the second boss 22 are misaligned or skewed due to uneven force.

[0090] Preferably, the protection structure 313 is an arc-shaped structure provided on the engaging member 31 .

[0091] Specifically, Figure 1 and Figure 4 As shown, the L-shaped right-angled outer portion and the side edges of the engaging member 31 are rounded to form an arc-shaped protective structure 313 to reduce the discharge effect caused by the sharp corners of the outer shape.

Of course, preferably, the first clamping structure 111 is set as an annular protrusion, and the second clamping structure 211 is set as an annular groove.

[0096] Continue reading Figure 1 , and then see Figure 5 , Figure 5 It is a schematic structural diagram of the shielding cover of the present invention.

[0099] It should be noted that, in practical applications, the present invention does not impose any limitation on the shape of the shielding cover 4. For example, the shielding cover 4 can be set to a hemispherical shape, or the shielding cover 4 can be set to an ellipsoidal shape, or the shielding cover 4 can be set to any other possible shape, etc. Such adjustments and changes to the specific shape of the shielding cover 4 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0100] Preferably, the shielding cover 4 is a hemispherical thin-wall structure.

[0101] It should be noted that, in actual applications, the present invention does not impose any limitation on the specific connection method between the shielding cover 4 and the metal outer tube 2. For example, the shielding cover 4 and the metal outer tube 2 can be arranged to be threadedly connected, or the shielding cover 4 and the metal outer tube 2 can be arranged to be adhesively connected, or the shielding cover 4 and the metal outer tube 2 can be arranged to be connected by a snap fastener, etc. Such adjustments and changes to the specific connection method between the shielding cover 4 and the metal outer tube 2 do not deviate from the principle and scope of the present invention, and should be included in the protection scope of the present invention.

[0102] Preferably, if Figure 1 , Figure 3 and Figure 5 As shown, the metal outer tube 2 is provided with an external thread 214 , and the shielding cover 4 is provided with a threaded hole 41 matched with the external thread 214 . The threaded hole 41 cooperates with the external thread 214 to fix the shielding cover 4 on the metal outer tube 2 .

[0103] In order to improve the installation stability of the shielding cover 4 on the metal outer tube 2, after the shielding cover 4 is installed on the metal outer tube 2, adhesive can be applied in the threaded hole 41 to prevent the shielding cover 4 from falling off the metal outer tube 2, or a snap-fit ​​structure can be provided on the shielding cover 4 and the metal outer tube 2 to prevent the shielding cover 4 from falling off the metal outer tube 2.

[0104] Preferably, a limiting structure (not shown in the figure) is provided on the metal outer tube 2 , and the limiting structure is configured to prevent the metal outer tube 2 from passing through the shielding cover 4 .

[0105] Through such an arrangement, when the shielding cover 4 is installed, it is possible to prevent the metal outer tube 2 from protruding outside the shielding cover 4 to cause tip discharge, thereby improving the safety of the charged device.

[0106] It should be noted that it is not limited to setting a limiting structure to prevent the metal outer tube 2 from passing through the shielding cover 4. For example, the external thread 214 on the metal outer tube 2 can also be set to match the height of the threaded hole 41 to prevent the metal outer tube 2 from passing through the shielding cover 4.

[0107] The specific assembly process of the insulating sealing connection assembly of the present invention is described in detail below.

[0108] First, the mounting column 312 on the engaging part 31 is inserted into the mounting groove 212 on both sides of the side ear 213 through the avoidance opening 2133, so as to pre-install the engaging part 31 on the metal outer tube 2, and then the insulating hose 5 is passed through the threaded hole 41 on the shielding cover 4, so that the shielding cover 4 is first put on the insulating hose 5, and then the insulating hose 5 is passed through the inside of the second tube body 21 and extends out from the end close to the second boss 22, and then the insulating hose 5 is put on the outer wall of the first tube body 11 until it contacts the first boss 12.

[0109] After the insulating hose 5 is sleeved on the first tube body 11, the inner wall of the second tube body 21 is sleeved onto the first tube body 11 along the outer wall of the insulating hose 5, and the first boss 12 and the second boss 22 are adjusted to align. When the joint surface of the second tube body 21 and the first tube body 11 is blocked, the clamping parts 31 on both sides are pulled to the top of the mounting groove 212, and the clamping parts 31 are rotated relative to the metal outer tube 2 with the mounting column 312 as the axis, so that the clamping parts 31 are buckled onto the two sides of the first boss 12, so that the first boss 12 and the second boss 22 is inserted into the guide groove 311. At this time, the locking bolts corresponding to the two engaging parts 31 are rotated until the locking bolts are inserted into the limiting holes 221 on the second boss 22. The locking bolts continue to be rotated, and the locking bolts will drive the second boss 22 to move toward the first boss 12, and drive the second tube body 21 to move toward the first tube body 11. When the locking bolt presses the second boss 22 onto the first boss 12, the insulating hose 5 is clamped between the inner wall of the second tube body 21 and the outer wall of the first tube body 11.

[0110] When the insulating hose 5 is clamped between the inner wall of the second tube body 21 and the outer wall of the first tube body 11, the sealed connection between the metal inner tube 1 and the insulating hose 5 is achieved. At this time, the shielding cover 4 is directed toward the metal outer tube 2, and the threaded hole 41 is matched with the external thread 214 on the metal outer tube 2, and the metal outer tube 2 does not exceed the outside of the shielding cover 4, thereby completing the fixing of the shielding cover 4 on the metal outer tube 2. Finally, the shielding cover 4 is firmly connected to the metal outer tube 2 by adhesive or snaps to prevent loosening, thereby completing the assembly of the insulating sealing connection component.
