[0024] The technical solutions of this utility model will be clearly and completely described below with reference to the embodiments of this utility model. Obviously, the described embodiments are only some embodiments of this utility model, and not all embodiments. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the scope of protection of this utility model.

[0025] Example

[0026] like Figures 1-3As shown, the plug-in heating tube 1 includes a heating tube 1, a first plug-in socket 2 and a second plug-in socket 3 are provided between the heating tube 1 and the wire. The first plug-in socket 2 has a first plug-in end 4, and the second plug-in socket 3 has a first plug-in groove 5. The first plug-in end 4 is used to plug into the first plug-in groove 5. After the first plug-in end 4 is plugged into the first plug-in groove 5, the heating tube 1 and the wire are electrically connected. It also includes a locking component 6 provided on the first plug-in socket 2 and the second plug-in socket 3. The locking component 6 is used to fix or not fix the first plug-in socket 2 and the second plug-in socket 3.

[0027] In this embodiment, a heating element 1 and a wire electrically connected to it are included. A first connector 2 and a second connector 3 are respectively provided between the heating element 1 and the wire. The first connector 2 has a first connector end 4, and the second connector 3 has a first connector groove 5 that is adapted to the first connector end 4. When the first connector end 4 is inserted into the first connector groove 5, the heating element 1 and the wire are electrically connected, thereby enabling normal heating operation. In addition, to ensure the stability after connection, a locking component 6 is also provided on the first connector 2 and the second connector 3. The locking component 6 can fix or not fix the first connector 2 and the second connector 3 as needed. When it is necessary to fix both, the locking component 6 will lock the first connector 2 and the second connector 3 tightly to prevent the connector from loosening due to external forces or other factors, and ensure the reliability of the connection between the heating tube 1 and the wire. When it is necessary to disassemble the heating tube 1 or the wire for replacement or maintenance, the locking component 6 can quickly release the fixed state, so that the first connector 2 and the second connector 3 can be easily separated, which is convenient for operation and improves the ease of use and maintenance efficiency of the heating tube 1.

[0028] Furthermore, the locking component 6 includes several spring pieces 7 circumferentially arranged on the first plug end 4. The first plug groove 5 has several locking grooves 8 that correspond one-to-one with the spring pieces 7. All locking grooves 8 are connected to the first plug groove 5. After the first plug end 4 slides into the first plug groove 5, the spring pieces 7 are used to slide into the corresponding locking grooves 8. The bottom of the first plug groove 5 is a conductive end 9. After the first plug end 4 is inserted into the first plug groove 5, the first plug end 4 and the conductive end 9 are arranged in abutment.

[0029] In this embodiment, the locking component 6 has the following specific structure: A plurality of spring pieces 7 are evenly arranged circumferentially on the outer peripheral wall of the first insertion end 4. These spring pieces 7 have a sheet-like structure, with both ends fixedly connected to the first insertion end 4, and a free end in the middle, extending radially outward from the first insertion end 4. A plurality of locking grooves 8 are correspondingly arranged on the inner wall of the first insertion groove 5. The number of locking grooves 8 corresponds one-to-one with the number of spring pieces 7, and each locking groove 8 communicates with the first insertion groove 5. When the first insertion end 4 slides into the first insertion groove 5, the spring piece 7 will gradually be squeezed by the inner wall of the first insertion groove 5 as the first insertion end 4 is inserted, causing elastic deformation until it slides into the corresponding locking groove 8. At this time, the spring piece 7 is locked into the locking groove 8 under the action of elastic restoring force, thereby fixing the first insertion seat 2 and the second insertion seat 3 together, achieving the locking function. Meanwhile, the bottom of the first insertion slot 5 is a conductive end 9. When the first insertion end 4 is fully inserted into the first insertion slot 5, the end of the first insertion end 4 abuts against the conductive end 9, ensuring a stable electrical connection between the heating tube 1 and the wire, enabling the heating tube 1 to work normally. This locking component 6 not only enables quick locking and unlocking, but also improves the reliability and stability of the connection through the cooperation of the spring piece 7 and the snap-fit ​​slot 8, while ensuring the performance of the electrical connection.

[0030] Furthermore, the second connector 3 includes a connector rod 10, and the first connector groove 5 is located on the connector rod 10. The locking assembly 6 also includes a sliding sleeve 11 slidably disposed on the connector rod 10. The sliding sleeve 11 has an abutting end 12 and a yielding end 13. The abutting end 12 is used to abut the spring piece 7, and the yielding end 13 is used to yield the spring piece 7. After the sliding sleeve 11 slides on the connector rod 10, it is used to abut or yield the spring piece 7.

[0031] In this embodiment, the second connector 3 is also provided with a connector rod 10, and the first connector groove 5 is located on the side wall of the connector rod 10. In addition to the spring piece 7 provided on the first connector end 4 and the locking groove 8 on the first connector groove 5, the locking assembly 6 also includes a sliding sleeve 11. The sliding sleeve 11 can slide along the axial direction of the connector rod 10. One end of the inner side of the sliding sleeve 11 is an abutment end 12, and the other end is a clearance end 13. The abutment end 12 is used to tightly abut against the free end of the spring piece 7 when the sliding sleeve 11 slides to a certain position, thereby causing the spring piece 7 to undergo elastic deformation, allowing the spring piece 7 to slide out of the locking groove 8, further enhancing the locking effect of the first connector 2 and the second connector 3. The clearance end 13 is designed to have a certain space. When the sliding sleeve 11 slides to this position, the clearance end 13 can provide sufficient space for the free end of the spring piece 7, allowing it to remain in the locking groove 8, achieving accidental locking during operation. By sliding the sliding sleeve 11 on the plug-in rod 10, the contact or avoidance state of the spring piece 7 can be flexibly controlled, thereby realizing convenient operation of locking and unlocking the first plug-in socket 2 and the second plug-in socket 3. This structural design not only improves the connection stability of the plug-in heating tube 1, but also facilitates users to quickly disassemble and assemble according to actual needs, improving the convenience of use and maintenance.

[0032] Furthermore, the sliding sleeve 11 has several mounting slots 14, and also includes an elastic element 15 with one end disposed on the plug rod 10 and the other end disposed on the sliding sleeve 11 and located in the mounting slot 14. The elastic element 15 is used to provide a force for the avoidance end 13 to approach the spring piece 7.

[0033] In this embodiment, a plurality of mounting slots 14 are evenly arranged along the circumference of the sliding sleeve 11, and an elastic element 15 is provided in each mounting slot 14. One end of the elastic element 15 is fixed to the plug-in rod 10, and the other end is fixed in the mounting slot 14 of the sliding sleeve 11. This structure, through the setting of the elastic element 15, not only ensures the stability of the sliding sleeve 11 in the locked and unlocked states, but also realizes the automatic reset function of the sliding sleeve 11, further improving the ease of use and reliability of the plug-in heating tube 1.

[0034] Furthermore, the second connector 3 is provided with a quick-connect port 16, and a conductive element 17 is provided inside the second connector 3 between the conductive end 9 and the quick-connect port 16. After the power supply and the quick-connect port 16 are connected, the conductive end 9 is energized.

[0035] In this embodiment, a quick-connect socket 16 is provided on the second connector 3. This quick-connect socket 16 is located on the outside of the second connector 3, facilitating quick connection of the power cord by the user. Inside the second connector 3, a conductive element 17 is provided between the conductive end 9 and the quick-connect socket 16. This conductive element 17 can be a section of conductive metal sheet or a conductive wire. When the user inserts the power cord into the quick-connect socket 16, the power supply is connected to the conductive end 9 through the conductive element 17, thus energizing the conductive end 9. At this time, when the first connector 4 is inserted into the first connector slot 5 and abuts against the conductive end 9, the heating tube 1 can obtain power through the conductive end 9 and begin normal operation. This design makes the power connection of the heating tube 1 simpler and faster. Users do not need to perform complex wiring or soldering operations; they only need to insert the power cord into the quick-connect socket 16 to energize the heating tube 1, greatly improving ease of use. Simultaneously, the conductive element 17 ensures the stability and safety of power transmission, avoiding malfunctions caused by poor contact or short circuits.

[0036] Furthermore, the heating tube 1 is a U-shaped tube, and several fins 18 are arranged on the heating tube 1, and both ends of the heating tube 1 are set on the first plug-in seat 2.

[0037] In this embodiment, both ends of the U-shaped heating tube 1 are fixedly connected to the first connector 2, and are electrically connected to the wires through the first connector 2. To further enhance the heating effect, several fins 18 are arranged along the length of the outer surface of the U-shaped heating tube 1. These fins 18 can be made of metal, such as aluminum or copper, which can effectively increase the contact area between the heating tube 1 and the surrounding medium (such as air or liquid), promote heat transfer, and make the heating process more uniform and efficient. Through this structural design, the U-shaped heating tube 1 not only has good heating performance, but also has both ends connected to the wires through the first connector 2. Combined with the locking component 6 and the quick-connect socket 16, the heating tube 1 can be quickly installed, disassembled, and powered on, greatly improving the flexibility of use and ease of maintenance of the heating tube 1.

[0038] Furthermore, the first connector 2 has a threaded hole 19, and the two ends of the heating tube 1 are respectively threaded into the two threaded holes 19.

[0039] In this embodiment, the first connector 2 is provided with threaded holes 19, with two threaded holes 19 located on the two first connectors 2 respectively, and adapted to the two ends of the heating tube 1. The two ends of the heating tube 1 are respectively provided with external threads, and the two ends of the heating tube 1 are tightly fixed in the threaded holes 19 of the first connector 2 through a threaded connection. This threaded connection method not only ensures the mechanical connection strength between the heating tube 1 and the first connector 2, but also guarantees the reliability of the electrical connection. Through the threaded connection, the two ends of the heating tube 1 can be firmly fixed on the first connector 2, preventing the heating tube 1 from loosening due to vibration or external force, thereby improving the stability and safety of the heating tube 1 in use. At the same time, the threaded connection also facilitates the installation and disassembly of the heating tube 1, allowing users to quickly replace the heating tube 1 as needed, further improving the maintenance convenience of the heating tube 1.
