Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing connection technology, specifically providing an insulating sealing connection assembly and a live device including the insulating sealing connection assembly. Background Technology

[0002] Currently, most existing insulating hoses and live equipment connection sealing joints use threaded connections or more complex compression fitting connections.

[0003] However, for threaded sealing joints, the threaded connection structure clamps the inner and outer metal pipes through the meshing of the inner and outer threads, thereby fixing the insulating hose to the inner metal pipe and playing a role in sealing connection and preventing detachment. However, in limited spaces, it is not possible to quickly disassemble and assemble, and it is only suitable for areas with relatively large installation space. In addition, this type of sealing joint has many parts, the installation steps are complicated, and there is a risk of parts falling off during the installation process, which makes installation inconvenient.

[0004] While the compression fitting method is suitable for installation in limited spaces and has a wider range of applications, it is more complex in structure and more cumbersome in installation. It requires first binding the insulating hose to one end of the metal pipe fitting with a metal clamp, then using the compression fitting to connect the metal pipe fittings, adding an extra sealing gasket at the connection point, and finally tightening the compression fitting with bolts to achieve a seal at the connection.

[0005] In the existing technology, due to the inability of existing sealed connection joints to be used for quick disassembly and assembly in limited spaces, and the risk of parts falling off during installation, there is an urgent need to develop a sealed connection joint with a simpler structure and easier disassembly and assembly. Utility Model Content

[0006] The present invention aims to solve the above-mentioned technical problems to at least a certain extent, namely, to solve the problems that existing sealed connection joints have complex structures, cumbersome installation processes, and are not suitable for quick assembly and disassembly in limited spaces.

[0010] In the preferred embodiment of the above-mentioned insulating and sealing connection assembly, the snap-fit ​​member further includes an elastic element disposed between the locking bolt and the snap-fit ​​member. The elastic element is capable of applying 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; and / or, the snap-fit ​​member is further provided with a protective structure disposed between two adjacent sides of the snap-fit ​​member and capable of preventing the snap-fit ​​member from discharging.

[0011] In the preferred embodiment of the above-mentioned insulating and sealing connection assembly, the outer metal tube is provided with a first mounting structure, and the engaging member is provided with a second mounting structure. The first mounting structure and the second mounting structure cooperate to install the engaging member onto the outer metal tube; and / or, the outer wall of the first tube body is provided with a first clamping structure, and the inner wall of the second tube body is provided with a second clamping structure adapted to the first clamping structure. 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 embodiment of the above-mentioned insulating and sealing connection assembly, the metal outer tube is provided with a side lug, the first mounting structure is a mounting groove formed on the side lug, and the second mounting structure is a mounting post symmetrically arranged on the engaging member. When installed, the two mounting posts are respectively located in the mounting groove, and the engaging member can also rotate relative to the side lug about the mounting post as an axis.

[0013] In the preferred embodiment of the above-mentioned insulating and sealing connection assembly, the first boss includes at least two first fixing platforms distributed circumferentially along the first tube body, the second boss includes at least two second fixing platforms distributed circumferentially along the second tube body, the second fixing platforms are arranged in a one-to-one correspondence with the first fixing platforms, and the number of the snap-fit ​​members is at least two and is arranged in a one-to-one correspondence with the first fixing platforms and the second fixing platforms.

[0014] In the preferred embodiment of the above-mentioned insulating and sealing connection assembly, the insulating and sealing connection assembly further includes a shield, which is connected to the outer metal tube and can cover the outer metal tube, the inner metal tube and the snap-fit ​​member.

[0015] In the preferred embodiment of the above-mentioned insulating and sealing connection assembly, the outer metal tube is provided with an external thread, and the shielding cover is provided with a threaded hole adapted to the external thread. The threaded hole and the external thread cooperate to fix the shielding cover on the outer metal tube; and / or, the outer metal tube is provided with a limiting structure, which is configured to prevent the outer metal tube from passing through the shielding cover.

[0016] In a second aspect, the present invention provides a live-line device, the live-line device comprising the insulating and sealed connection assembly described in any of the preceding claims.

[0017] When the above-mentioned preferred technical solution is adopted, the second fixing part can be clamped onto the first fixing part by the snap-fit ​​component, thereby clamping the insulating hose between the inner metal tube and the outer metal tube, realizing quick installation and disassembly. Compared with the existing insulating sealing connection assembly that uses threaded connection, no threaded connection is required, making assembly more convenient. Due to fewer parts, the risk of parts falling off during installation is lower. At the same time, quick assembly and disassembly can be achieved in a limited space. Compared with the existing compression fitting connection method, the structure is simpler and the assembly and disassembly are more convenient, greatly improving the assembly efficiency of the insulating sealing connection assembly.

[0018] Furthermore, by configuring the snap-fit ​​component to include a snap-fit ​​element and a locking element, on the one hand, the snap-fit ​​element can restrict the movement of the first boss, and the locking element can drive the second boss to move toward the first boss, so that the inner wall of the second tube body and the outer wall of the first tube body are pressed against each other, thereby clamping the insulating hose between the first tube body and the second tube body. This not only overcomes the friction between the insulating hose and the first and second tube bodies, making assembly easier, but also improves the sealing between the insulating hose and the first tube body. On the other hand, by providing a guide structure on the snap-fit ​​element, the second boss can move toward the first boss along the guide structure, preventing the second boss from rotating during the movement, thus making assembly smoother.

[0019] Furthermore, by setting a guide groove, the first and second bosses can be circumferentially limited, preventing them from rotating circumferentially during assembly. By setting the locking element to drive the second boss to move along the guide groove toward or away from the first boss, the second boss can be easily clamped onto the first boss or released from the first boss, thus facilitating the installation and disassembly of the insulating sealing connection assembly. Moreover, compared with setting the guide structure as a guide rod, setting the guide structure as a guide groove makes the structure of the insulating sealing connection assembly simpler and reduces the number of parts.

[0020] Furthermore, by setting the locking element as a locking bolt, the locking bolt can be engaged with the bolt hole on the engaging element, which can both drive the second boss to move toward the first boss and clamp the second boss onto 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 incorporating an elastic element, the elastic element can undergo elastic deformation and apply a force parallel to the central axis of the locking bolt. This results in greater friction between the locking bolt and the bolt hole, thereby preventing the locking bolt from coming out of the bolt hole and effectively preventing the live device from loosening and failing during operation.

[0022] Furthermore, by setting a protective structure between two adjacent sides of the snap-fit ​​component, the discharge effect caused by the sharp corners of the shape can be reduced, thereby improving the safety of the insulated and sealed connection assembly.

[0023] Furthermore, by setting the first installation structure and the second installation structure, it is easier to install the snap-fit ​​component onto the outer metal tube, thereby achieving pre-installation of the snap-fit ​​component and further improving the assembly efficiency of the insulating and sealing connection assembly. By setting the first clamping structure and the second clamping structure, the friction between the insulating hose and the inner and outer metal tubes can be increased, thereby more stably clamping the insulating hose between the inner and outer metal tubes and further improving the sealing effect of the insulating and sealing connection assembly.

[0024] Furthermore, by setting the first mounting structure as mounting grooves formed on both sides of the side ear and setting the second mounting structure as a mounting post, on the one hand, the mounting post can be used to cooperate with the mounting groove to pre-install the locking part onto the metal outer tube, improving assembly efficiency. On the other hand, the locking part can rotate relative to the side ear with the mounting post as the axis. During assembly, the locking part can be rotated relative to the side ear to make the locking part snap onto the bottom of the first boss, which facilitates the opening and closing of the locking part and further improves the convenience of assembly.

[0025] Furthermore, by setting up a shield, the anti-corona effect of the insulating and sealed connection component can be achieved, avoiding damage to the insulating hose and other structures caused by the discharge of the insulating and sealed connection component, further improving the safety of the insulating and sealed connection component. Furthermore, by setting up a limiting structure, the metal outer tube can be prevented from passing through the shield, thereby preventing tip discharge.

[0026] Furthermore, the live-line device further provided by this utility model, based on the aforementioned insulating and sealing connection assembly, possesses the beneficial effects of the aforementioned insulating and sealing connection assembly due to the inclusion of the aforementioned insulating and sealing connection assembly. Compared with the previous improved live-line device, the live-line device of this utility model has higher safety in use, better sealing performance of the pipe joint, and higher assembly and disassembly efficiency of the insulating and sealing connection assembly.

[0035] Preferred embodiments of the present invention will now be described with reference to the accompanying drawings. Those skilled in the art should understand that these embodiments are merely illustrative of the technical principles of the present invention and are not intended to limit the scope of protection of the present invention.

[0036] It should be noted that in the description of this utility model, terms such as "upper," "lower," "inner," and "outer," which indicate direction or positional relationships, are based on the direction or positional relationships shown in the accompanying drawings. These are used merely for ease of description and do not indicate or imply that the device or element must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model. Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance.

[0037] Furthermore, it should be noted that, in the description of this utility model, unless otherwise explicitly specified and limited, the terms "installation," "setting," and "connection" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0038] Specifically, please refer to Figure 1 , Figure 1 This is a schematic diagram of the structure of the insulating and sealing connection assembly of this utility model.

[0039] like Figure 1 As shown, the insulating and sealing connection assembly of this utility model includes an insulating hose 5, a metal inner tube 1, a metal outer tube 2, and a snap-fit ​​component 3. The insulating hose 5 is made of 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] The inner metal tube 1 is provided with a first fixing part, and the outer metal tube 2 is provided with a second fixing part that is adapted to the first fixing part. The snap-fit ​​member 3 is configured to snap the second fixing part onto the first fixing part, so as to clamp the insulating hose 5 between the inner metal tube 1 and the outer metal tube 2.

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

[0042] With this configuration, the second fixing part can be clamped onto the first fixing part by the snap-fit ​​component 3, thereby clamping the insulating hose 5 between the inner metal tube 1 and the outer metal tube 2, enabling quick installation and disassembly. Compared with the existing insulating sealing connection assembly that uses threaded connections, no threaded connection is required, making assembly more convenient. Due to the fewer parts, the risk of parts falling off during installation is lower. At the same time, it can achieve quick assembly and disassembly in a limited space. Compared with the existing ferrule connection method, it makes the structure simpler and the assembly and disassembly more convenient, greatly improving the assembly efficiency of the insulating sealing connection assembly.

[0043] It should be noted that this utility model does not impose any limitations 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 a circle, and correspondingly, the outer cross-section of the metal inner tube 1 can also be a circle. Alternatively, the inner cross-section of the insulating hose 5 can be set to a square, and correspondingly, the outer cross-section of the metal inner tube 1 can also be a 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 this utility model and should be included within the protection scope of this utility model.

[0044] Preferably, such as Figure 1 As shown, the inner cross-section of the insulating hose 5 is circular, and the outer cross-section of the metal inner tube 1 is also circular.

[0045] It should be noted that this utility model 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 correspondingly, the inner cross-section of the metal outer tube 2 can also be circular. Alternatively, the outer cross-section of the insulating hose 5 can be set to be square, and correspondingly, the inner cross-section of the metal outer tube 2 can also be 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 this utility model and should be included within the protection scope of this utility model.

[0046] Preferably, such as 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 practical applications, those skilled in the art can configure the first fixing part as the first protrusion 12 and the second fixing part as the second protrusion 22. When installed, the second protrusion 22 can be locked onto the first protrusion 12. Alternatively, the first fixing part can be configured as the first connecting ear and the second fixing part as the connecting ear. When installed, the second connecting ear can be locked onto the first connecting ear. Or, the first fixing part and the second fixing part can be configured in any other possible form, etc. Such adjustments and changes to the specific configuration types of the first fixing part and the second fixing part do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model.

[0048] Continue reading Figure 1 And then refer to Figures 2 to 4 , Figure 2 This is a schematic diagram of the structure of the metal inner tube of this utility model; Figure 3 This is a schematic diagram of the structure of the metal outer tube of this utility model;

[0049] Figure 4 This is a schematic diagram of the snap-fit ​​component of this utility model.

[0050] Preferably, such as Figures 1 to 3 As shown, the inner metal tube 1 includes a first tube body 11 and a first protrusion 12 disposed on the first tube body 11, and the outer metal tube 2 includes a second tube body 21 and a second protrusion 22 disposed on the second tube body 21. The first protrusion 12 forms a first fixing part, and the second protrusion 22 forms a second fixing part.

[0051] like Figure 1 and Figure 4 As shown, the snap-fit ​​component 3 includes a snap-fit ​​component 31 and a locking component 32. The snap-fit ​​component 31 can restrict the movement of the first boss 12. The snap-fit ​​component 31 also has a guide structure. The locking component 32 is configured to drive the second boss 22 to move along the guide structure toward the direction close to the first boss 12, thereby snapping the second boss 22 onto the first boss 12. When installed, the insulating hose 5 is clamped between the first tube body 11 and the second tube body 21.

[0052] By configuring the snap-fit ​​member 3 to include a snap-fit ​​member 31 and a locking member 32, on the one hand, the snap-fit ​​member 31 can restrict the movement of the first boss 12, and the locking member 32 can drive the second boss 22 to move toward the first boss 12, so that the inner wall of the second tube 21 and the outer wall of the first tube 11 are pressed against each other, thereby clamping the insulating hose 5 between the first tube 11 and the second tube 21. This not only overcomes the friction between the insulating hose 5 and the first tube 11 and the second tube 21, making assembly easier, but also improves the sealing between the insulating hose 5 and the first tube 11. On the other hand, by providing a guide structure on the snap-fit ​​member 31, the second boss 22 can move toward the first boss 12 along the guide structure, preventing the second boss 22 from rotating during the movement, thus making assembly smoother.

[0053] It should be noted that the first protrusion 12 can be integrally formed with the first tube body 11, or the first protrusion 12 can be snap-fitted to the first tube body 11, or the first protrusion 12 can be fixedly connected to the first tube body 11 by fasteners, etc. Such adjustments and changes to the specific connection method between the first protrusion 12 and the first tube body 11 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0054] For example, the first boss 12 is integrally formed with the first tube body 11.

[0055] It should be noted that the second protrusion 22 can be integrally formed with the second tube body 21, or the second protrusion 22 can be snapped into the second tube body 21, or the second protrusion 22 can be fixedly connected to the second tube body 21 by fasteners, etc. Such adjustments and changes to the specific connection method between the second protrusion 22 and the second tube body 21 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0056] For example, the second boss 22 is integrally formed with the second tube body 21.

[0057] It should be noted that, in practical applications, those skilled in the art can configure the guide structure as a guide groove 311, whereby the first boss 12 and the second boss 22 can slide along the guide groove 311 to move the second boss 22 toward the first boss 12. Alternatively, the guide structure can be configured as a guide rod, whereby the first boss 12 and the second boss 22 can slide along the guide rod to move the second boss 22 toward the first boss 12. Furthermore, the guide structure can be configured as 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 principles and scope of this utility model and should all be included within the protection scope of this utility model.

[0058] Preferably, such as Figures 1 to 4 As shown, the guide structure is a guide groove 311 formed in the engaging 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. The locking member 32 is drivenly connected to the second boss 22 and can drive the second boss 22 to move along the guide groove 311 toward the direction of approaching or moving away from the first boss 12.

[0059] By setting the guide groove 311, the first boss 12 and the second boss 22 can be circumferentially limited, preventing the first boss 12 and the second boss 22 from rotating circumferentially during assembly. By setting the locking member 32 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 easily locked onto the first boss 12 or released from the first boss 12, thereby facilitating the installation and disassembly of the insulating sealing connection assembly of the locking member 3. Moreover, compared with setting the guide structure as a guide rod, setting the guide structure as a guide groove 311 makes the structure of the insulating sealing connection assembly simpler and has fewer parts.

[0060] It should be noted that the locking member 32 can be configured as a locking bolt, and the engaging member 31 is provided with a bolt hole 314 adapted to the locking bolt. The locking bolt can pass through the bolt hole 314 and be rotatably connected to the second boss 22. The locking bolt and the bolt hole 314 cooperate to drive the second boss 22 to move toward the first boss 12 and lock the second boss 22 onto the first boss 12. Alternatively, the locking member 32 can be configured as a pressing rod, with a first locking structure on the first boss 12 and a second locking structure on the second boss 22. The pressing rod abuts against the second boss 22. When the operator presses it toward the first boss 12, the second locking structure can be locked onto the first locking structure, thereby locking the second boss 22 onto the first boss 12. Alternatively, the locking member 32 can be configured in any other possible form, etc. Such adjustments and changes to the specific configuration of the locking member 32 do not deviate from the protection scope of this utility model.

[0061] Preferably, such as Figure 1 and Figure 4 As shown, the locking member 32 is a locking bolt, and the engaging member 31 is provided with a bolt hole 314 that is adapted to the locking bolt. 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 lock the second boss 22 onto the first boss 12.

[0062] By setting the locking member 32 as a locking bolt, the locking bolt can cooperate with the bolt hole 314 on the engaging member 31, which can both drive the second boss 22 to move toward the first boss 12 and lock the second boss 22 onto 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.

[0063] It should be noted that, in practical applications, this utility model does not limit the specific connection method of the locking bolt and the second boss 22. For example, a bearing can be provided on the second boss 22 to enable the locking bolt to be rotatably connected to the second boss 22. Alternatively, a limiting hole 221 adapted to the locking bolt can 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. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0064] Preferably, such as Figure 3 As shown, the second boss 22 is provided with a limiting hole 221 that is adapted to the locking bolt. During assembly, the locking bolt is located in the limiting hole 221 and can rotate relative to the second boss 22.

[0065] With this configuration, as the locking member 32 drives the second boss 22 to move toward the first boss 12, the locking bolt can engage with the limiting hole 221, thereby restricting the locking bolt from moving radially and thus preventing the locking bolt from becoming misaligned or skewed.

[0066] Preferably, such as Figure 1 As shown, the snap-fit ​​component 3 also includes an elastic element 33, which is disposed between the locking bolt and the snap-fit ​​component 31. The elastic element 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.

[0067] By setting the elastic element 33, the elastic element 33 can undergo elastic deformation and apply a force parallel to the central axis of the locking bolt to the locking bolt, thereby creating a large frictional force between the locking bolt and the bolt hole 314. This can prevent the locking bolt from coming out of the bolt hole 314 and effectively prevent the live device from loosening and failing during operation.

[0068] It should be noted that this utility model does not limit the specific type of the elastic element 33, as long as it can undergo elastic deformation and apply elastic force to the locking bolt. For example, the elastic element 33 can be set as a spring, or it can be set as an elastic sheet, or it can be set as an elastic sheet and a washer 331, etc. Such adjustments and changes to the specific type of the elastic element 33 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0069] Preferably, such as Figure 1 As shown, the elastic element 33 includes a gasket 331 and an elastic sheet 332.

[0070] Preferably, the metal outer tube 2 is provided with a first mounting structure, and the locking member 31 is provided with a second mounting structure. The first mounting structure and the second mounting structure cooperate to install the locking member 31 onto the metal outer tube 2.

[0071] By setting up a first mounting structure and a second mounting structure, it is easy to install the snap-fit ​​component 31 onto the metal outer tube 2, thereby achieving the pre-installation of the snap-fit ​​component 31 and further improving the assembly efficiency of the insulating and sealing connection assembly.

[0072] Preferably, such as 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. The second mounting structure is a mounting post 312 symmetrically arranged on the locking member 31. When installed, the two mounting posts 312 are located in the two mounting grooves 212 respectively. The locking member 31 can also rotate relative to the side ears 213 with the mounting post 312 as the axis.

[0073] With this configuration, on the one hand, the mounting post 312 can be used to cooperate with the mounting groove 212 to pre-install the locking piece 31 onto the metal outer tube 2, improving assembly efficiency. On the other hand, the locking piece 31 can rotate relative to the side ear 213 with the mounting post 312 as the axis. During assembly, the locking piece 31 can be rotated relative to the side ear 213 so that the locking piece 31 can be fastened to the bottom of the first protrusion 12, which facilitates the opening and closing of the locking piece 31 and further improves the convenience of assembly.

[0074] Specifically, the locking component 31 is provided with a limiting groove, and two mounting posts 312 are symmetrically arranged in the limiting groove. The mounting posts 312 can only move within the mounting groove 212 and have a certain degree of freedom, which facilitates the opening and closing and positioning clamping of the locking component 31.

[0075] It should be noted that the first mounting structure is not limited to being a mounting groove 212 and the second mounting structure is not limited to being a mounting post 312. For example, the first and second mounting structures can also be configured as a mounting post 312 and a mounting ring, or as a mounting protrusion and a mounting groove 212, etc. Such flexible adjustments and changes do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0076] Of course, the preferred option is, such as Figure 3 and Figure 4 As shown, the first mounting structure is configured as a mounting groove 212, and the second mounting structure is configured as a mounting column 312.

[0077] Preferably, the side ear 213 is provided with a clearance opening 2133 that is adapted to the mounting post 312, so that the mounting post 312 can enter the mounting groove 212 through the clearance opening 2133, thereby further improving the ease of assembly.

[0078] It should be noted that, in practical applications, the first protrusion 12 can be configured to include two first fixing platforms 121 spaced apart circumferentially along the first tube 11, and the second protrusion 22 can be configured to include two second fixing platforms 222 spaced apart circumferentially along the second tube 21. The number of snap-fit ​​members 3 is also two, and each of the two second fixing platforms 222 is snapped onto the first fixing platform 121. Alternatively, the first protrusion 12 can be configured to include multiple first fixing platforms 121 spaced apart circumferentially along the first tube 11, and the second protrusion 22 can be configured to include multiple second fixing platforms 222 spaced apart circumferentially along the second tube 21. The number of snap-fit ​​members 3 is also multiple, and each of the multiple second fixing platforms 222 is snapped onto the first fixing platform 121, and so on. Such adjustments and changes to the specific number of snap-fit ​​members 3 do not deviate from the principle and scope of this utility model and should all be included within the protection scope of this utility model.

[0079] Preferably, such as Figure 2 and Figure 3 As shown, the first boss 12 includes at least two first fixing platforms 121 distributed circumferentially along the first tube body 11, and the second boss 22 includes at least two second fixing platforms 222 distributed circumferentially along the second tube body 21. The second fixing platforms 222 are arranged in a one-to-one correspondence with the first fixing platforms 121. The number of snap-fit ​​members 3 is at least two and is arranged in a one-to-one correspondence with the first fixing platforms 121 and the second fixing platforms 222.

[0080] With this configuration, the first protrusion 12 and the second protrusion 22 can be clamped together at multiple points by the clamping member 3. On the one hand, this can prevent the metal inner tube 1 and the metal outer tube 2 from being not firmly clamped due to too few clamping points. On the other hand, it can also prevent the first protrusion 12 and the second protrusion 22 from being misaligned or tilted due to uneven force.

[0081] It should be noted that, in practical applications, those skilled in the art can configure the side ear 213 to be integrally formed with the metal outer tube 2, or the side ear 213 can be fixedly connected to the metal outer tube 2 by fasteners, or the side ear 213 can be snapped to the metal outer tube 2, etc. Such adjustments and changes to the specific connection method between the side ear 213 and the metal outer tube 2 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0082] Preferably, the side ear 213 is integrally formed with the metal outer tube 2; more preferably, the side ear 213 and the metal outer tube 2 are integrally cast.

[0083] Specifically, the side ear 213 includes a first support plate 2131 and a second support plate 2132. The first support plate 2131 is radially parallel to the outer metal tube 2 and connected to the outer wall of the outer metal tube 2. The second support plate 2132 is located at the edge of the first support plate 2131 and is perpendicular to the first support plate 2131. The two sides of the first support plate 2131 and the second support plate 2132 respectively form a mounting groove 212.

[0084] It should be noted that in practical applications, this utility model does not impose any limitations on the specific shape of the latching component 31. For example, the latching component 31 can be set as an L-shape, or it can be set as a long strip, or it can be set as any other possible form, etc. Such adjustments and changes to the specific shape of the latching component 31 do not deviate from the principle and scope of this utility model and should be included within the protection scope of this utility model.

[0085] Preferably, the locking member 31 is L-shaped, which allows the locking member 31 to open and close over a wide range with the mounting post 312 as the fulcrum, making it easy to open and lock the locking member 31.

[0086] It should be noted that, in practical applications, those skilled in the art can configure the snap-fit ​​component 31 as being formed by casting, or as being formed by welding multiple components together, etc. Such adjustments and changes to the specific forming method of the snap-fit ​​component 31 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0087] Preferably, the snap-fit ​​component 31 is formed by casting, which ensures the overall structural strength and structural reliability.

[0088] Preferably, such as Figure 1 and Figure 4 As shown, the engaging component 31 is also provided with a protective structure 313, wherein the protective structure 313 is disposed between two adjacent sides of the engaging component 31 and can prevent the engaging component 31 from discharging.

[0089] By providing a protective structure 313 between two adjacent sides of the snap-fit ​​component 31, the discharge effect caused by the sharp corners of the shape can be reduced, thereby improving the safety of the insulated and sealed connection assembly.

[0090] It should be noted that, in practical applications, those skilled in the art can set the protective structure 313 as an arc-shaped structure, or they can set the protective structure 313 as an insulating protective sheet covering the snap-fit ​​member 31, etc. Such adjustments and changes to the specific setting type of the protective structure 313 do not deviate from the principle and scope of this utility model, and should all be included within the protection scope of this utility model.

[0091] Preferably, the protective structure 313 is an arc-shaped structure provided on the engaging member 31.

[0092] Specifically, such as Figure 1 and Figure 4 As shown, the outer L-shaped right angle and the sides of the engaging part 31 are rounded to form an arc-shaped protective structure 313, thereby reducing the discharge effect caused by the sharp corners of the shape.

[0093] Preferably, such as Figure 1 and Figure 2 As shown, a first clamping structure 111 is provided on the outer wall of the first tube 11, and a second clamping structure 211 adapted to the first clamping structure 111 is provided on the inner wall of the second tube 21. When installed, the first clamping structure 111 and the second clamping structure 211 cooperate to clamp the insulating hose 5 between the first tube 11 and the second tube 21.

[0094] By setting the first clamping structure 111 and the second clamping structure 211, the friction between the insulating hose 5 and the inner metal tube 1 and the outer metal tube 2 can be increased, thereby more stably clamping the insulating hose 5 between the inner metal tube 1 and the outer metal tube 2, and further improving the sealing effect of the insulating sealing connection assembly.

[0095] Specifically, such as Figure 1 and Figure 2 As shown, the first clamping structure 111 is an annular protrusion, and the second clamping structure 211 is an annular groove that matches the annular protrusion. When installed, the annular protrusion is located in the annular groove.

[0096] It should be noted that in practical applications, the design is not limited to setting the first clamping structure 111 as an annular protrusion and the second clamping structure 211 as an annular groove. For example, the first clamping structure 111 can also be set as an annular groove and the second clamping structure 211 as an annular protrusion, etc. Such adjustments and changes to the specific configurations of the first clamping structure 111 and the second clamping structure 211 do not deviate from the principles and scope of this utility model and should be included within the protection scope of this utility model. 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.

[0097] Continue reading Figure 1 And then refer to Figure 5 , Figure 5 This is a schematic diagram of the shielding cover of this utility model.

[0098] Preferably, such as Figure 1 and Figure 5As shown, the insulating and sealing connection assembly of this utility model also includes a shield 4, wherein the shield 4 is connected to the outer metal tube 2 and can cover the outer metal tube 2, the inner metal tube 1 and the snap-fit ​​member 3.

[0099] By setting the shield 4, the anti-corona effect of the insulating and sealed connection component can be achieved, avoiding damage to the insulating hose 5 and other structures caused by the discharge of the insulating and sealed connection component, and further improving the safety of the insulating and sealed connection component.

[0100] It should be noted that in practical applications, this utility model does not impose any limitations on the shape of the shielding cover 4. For example, the shielding cover 4 can be set as a hemisphere, or it can be set as an ellipsoid, or it can be set as 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 this utility model and should be included within the protection scope of this utility model.

[0101] Preferably, the shielding cover 4 is a hemispherical thin-walled structure.

[0102] It should be noted that, in practical applications, this utility model does not impose any limitations 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 connected by threads, or they can be connected by adhesive, or they can be connected by snap-fit, 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 this utility model and should all be included within the protection scope of this utility model.

[0103] Preferably, such as Figure 1 , Figure 3 and Figure 5 As shown, the metal outer tube 2 is provided with an external thread 214, and the shield 4 is provided with a threaded hole 41 that is adapted to the external thread 214. The threaded hole 41 and the external thread 214 cooperate to fix the shield 4 on the metal outer tube 2.

[0104] 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 to the threaded hole 41 to prevent the shielding cover 4 from falling off the metal outer tube 2. Alternatively, 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.

[0105] 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.

[0106] With this configuration, when the shielding cover 4 is installed, the metal outer tube 2 can be prevented from extending beyond the outside of the shielding cover 4, thereby preventing tip discharge and improving the safety of the live device.

[0107] It should be noted that the method is not limited to setting a limiting structure to prevent the metal outer tube 2 from passing through the shield 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 shield 4.

[0108] The following is a detailed description of the specific assembly process of the insulating and sealing connection assembly of this utility model.

[0109] First, the mounting post 312 on the snap fastener 31 is inserted into the mounting groove 212 on both sides of the side ear 213 through the clearance opening 2133, thereby pre-installing the snap fastener 31 onto the metal outer tube 2. 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 fitted onto the insulating hose 5. Then, the insulating hose 5 is passed through the inside of the second tube body 21 and extends out from the end near the second protrusion 22. Next, the insulating hose 5 is fitted onto the outer wall of the first tube body 11 until it contacts the first protrusion 12.

[0110] After the insulating hose 5 is fitted onto the first tube 11, the inner wall of the second tube 21 is fitted onto the first tube 11 along the outer wall of the insulating hose 5. Simultaneously, the first boss 12 and the second boss 22 are aligned. When the mating surface between the second tube 21 and the first tube 11 obstructs the connection, the locking pieces 31 on both sides are pulled up to the top of the mounting groove 212, and the locking pieces 31 are rotated relative to the metal outer tube 2 about the mounting post 312. This causes the locking pieces 31 to engage with both sides of the first boss 12, thus aligning the first boss 12 and the second boss 22. 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 hole 221 on the second boss 22. If the locking bolts are rotated, the locking bolts will drive the second boss 22 to move toward the first boss 12, and drive the second tube 21 to move toward the first tube 11. When the locking bolts press the second boss 22 onto the first boss 12, the insulating hose 5 is clamped between the inner wall of the second tube 21 and the outer wall of the first tube 11.

[0111] After the insulating hose 5 is clamped between the inner wall of the second tube 21 and the outer wall of the first tube 11, a sealed connection is achieved between the inner metal tube 1 and the insulating hose 5. At this time, the shield 4 is then oriented towards the outer metal tube 2, and the threaded hole 41 is engaged with the external thread 214 on the outer metal tube 2, ensuring that the outer metal tube 2 does not extend beyond the outer side of the shield 4, thus completing the fixation of the shield 4 on the outer metal tube 2. Finally, the shield 4 is securely connected to the outer metal tube 2 using adhesive or clips to prevent loosening, thus completing the assembly of the insulating and sealing connection assembly.

[0112] In a second aspect, the present invention also provides a live device, wherein the live device includes the insulating and sealing connection assembly described in any of the above claims.

[0113] It should be noted that, in practical applications, those skilled in the art can configure the live device as a generator, or as a household appliance such as a water dispenser or washing machine, or as any other possible type, etc. Such adjustments and changes to the specific applicable objects of the insulating and sealing connection components do not deviate from the principles and scope of this utility model and should all be included within the protection scope of this utility model.

[0114] The technical solution of this utility model has been described in conjunction with the preferred embodiments shown in the accompanying drawings. However, it will be readily understood by those skilled in the art that the protection scope of this utility model is obviously not limited to these specific embodiments. Without departing from the principle of this utility model, those skilled in the art can make equivalent changes or substitutions to the relevant technical features, and the technical solutions after these changes or substitutions will all fall within the protection scope of this utility model.
