[0036] Example 1

[0037] Reference Figures 1 to 5 This is the first embodiment of the present utility model, which provides the following achievable effects:

[0038] Connector 100;

[0039] Assembly unit 200 is disposed within connector 100. Assembly unit 200 is used for installing metal heating tube. Limiting component 300 is disposed within assembly unit 200. Limiting component 300 is used to limit assembly unit 200.

[0040] Rotating component 400 is disposed within connecting seat 100 and is used to adjust limiting component 300.

[0041] In use, the assembly unit 200 accommodates the installation of the metal heating tube and, in conjunction with the limiting component 300, restricts the assembly unit 200 to ensure the installation stability of the metal heating tube and prevent it from loosening during use. The rotating component 400 adjusts the limiting component 300. When disassembly is required, the state of the limiting component 300 can be quickly changed by operating the rotating component 400, releasing the restriction on the assembly unit 200 and enabling rapid disassembly of the metal heating tube. This greatly shortens the disassembly time and improves maintenance efficiency.

[0042] Example 2

[0043] Reference Figures 1 to 5 This is the second embodiment of the present invention, which differs from the previous embodiment in that...

[0044] The assembly unit 200 includes a heating tube body 201, which is movably disposed within the connecting seat 100. Two turntables 202 are rotatably connected to the heating tube body 201. Two movable slots 203 are provided in the connecting seat 100. An arc-shaped opening 204 is provided on one side of the inner wall of each of the two movable slots 203. A connecting rod 205 is slidably connected to each of the two arc-shaped openings 204. The two connecting rods 205 are fixedly connected to the corresponding turntables 202. A positioning block 206 is fixedly connected to the other end of each of the two connecting rods 205.

[0045] The turntable 202 cooperates with the connecting rod 205 to allow the positioning block 206 to slide within the movable groove 203 and the arc-shaped opening 204, facilitating the adjustment of the horizontal position. After rotating to a certain angle, the positioning block 206 cannot be removed in reverse, thus having a limiting effect and ensuring stable installation.

[0046] Specifically, the limiting component 300 includes two grooves 301, both of which are formed on one inner wall of the corresponding movable groove 203. A spring 302 is fixedly connected to one inner wall of each of the two grooves 301, and a positioning rod 303 is fixedly connected to the other end of each of the two springs 302. The two positioning rods 303 are interlocked with the corresponding positioning block 206.

[0047] The limiting component 300 pushes the positioning rod 303 to engage with the positioning block 206 via the spring 302, thereby limiting the heating tube body 201 to prevent it from shaking and loosening during use.

[0048] Specifically, the rotating assembly 400 includes an annular cavity 401, which is located at the center of the connecting seat 100. A winding wheel 402 is rotatably connected to one inner wall of the annular cavity 401. A knob 403 is fixedly connected to one side surface of the winding wheel 402. The knob 403 moves through the connecting seat 100. Two connecting ropes 404 are wound on the winding wheel 402. The other end of each of the two connecting ropes 404 is fixedly connected to a guide rod 405. Both guide rods 405 are fixedly connected to corresponding positioning rods 303. Through holes 406 are provided on both inner walls of the annular cavity 401. Both through holes 406 are interconnected with corresponding grooves 301.

[0049] In use, the winding wheel 402 can be controlled by the knob 403, which causes the connecting rope 404 and the guide rod 405 to move the positioning rod 303, thereby realizing the opening and closing adjustment of the limiting component 300. It only requires external operation, which improves the convenience and safety of operation and makes it easy to quickly release the fixed restriction on the heating tube body 201.

[0050] Example 3

[0051] Reference Figures 2 to 4 This is the third embodiment of the present invention, which differs from the previous embodiment in that...

[0052] Guide rings 4061 are fixedly connected to one side of the inner wall of each of the two through holes 406. The inner edge of the two guide rings 4061 is set with an arc surface. The two connecting ropes 404 are movably set in the corresponding guide rings 4061.

[0053] The inner wall of the guide ring 4061 is arc-shaped, which can effectively reduce the frictional loss of the connecting rope 404, extend its service life, and guide the connecting rope 404 to transmit power stably, ensuring smooth operation of the rotating component 400.

[0054] Specifically, an inner arc block 4031 is fixedly connected to one side surface of the knob 403, a movable ring 4032 is slidably connected to the inner arc block 4031, and a plug rod 4033 is fixedly connected to the movable ring 4032. Two slots 4034 are opened on one side surface of the connector 100, and the other end of the plug rod 4033 is inserted into one of the slots 4034.

[0055] The position of the knob 403 is fixed by connecting the insert rod 4033 to the slot 4034, ensuring the stable removal of the positioning rod 303 during disassembly and preventing it from resetting.

[0056] Specifically, the outer ring surfaces of the two turntables 202 are fixedly connected with a retaining plate 2021, and two recesses 2022 are fixedly connected to one side surface of the connecting seat 100. The two recesses 2022 are engaged with the corresponding retaining plates 2021.

[0057] The locking plate 2021 and the recessed block 2022 engage with each other, providing a limit for the heating tube body 201, enhancing the stability after installation, preventing it from rotating and shifting, and allowing for easy and efficient disassembly by simply rotating the turntable 202.

[0058] Specifically, two sealing rings 2011 are fixedly connected to the heating tube body 201, and both sealing rings 2011 are fixedly connected to the corresponding turntable 202.

[0059] During use, the sealing ring 2011 tightly connects the heating tube body 201 and the turntable 202, which can effectively prevent liquid or gas leakage and ensure the sealing and safety of the working environment of the heating tube body 201.

[0060] During use, first turn the knob 403 to insert the heating tube body 201 into the connector 100, then rotate the turntable 202 to drive the connecting rod 205 to slide in the arc-shaped opening 204, so that the retaining plate 2021 on the turntable 202 is connected to the concave block 2022, and the positioning block 206 is aligned with the groove 301. Then release the knob 403, and under the elastic force of the spring 302, the positioning rod 303 is inserted into the insertion hole of the positioning block 206, completing the stable installation of the heating tube body 201. Connect the insertion rod 4033 to the slot 4034 to complete the installation. At the same time, the two sealing rings 2011 are tightly fitted to the turntable 202 and the connector 100 to prevent leakage and ensure sealing.

[0061] When disassembly is required, the insertion rod 4033 is separated from the slot 4034, and then the knob 403 is rotated in the opposite direction to rotate the winding wheel 402. The connecting rope 404 wound on it is pulled, which in turn pulls the guide rod 405, causing the positioning rod 303 to overcome the elastic force of the spring 302 and be pulled out from the positioning block 206. At this time, the turntable 202 is rotated to disengage the clamping plate 2021 from the recess 2022, so that the heating tube body 201 can be removed from the connecting seat 100, realizing quick disassembly and effectively improving the disassembly efficiency of the metal heating tube.

[0062] It should be noted that the above embodiments are only used to illustrate the technical solution of this utility model and are not intended to limit it. Although this utility model has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solution of this utility model without departing from the spirit and scope of the technical solution of this utility model, and all such modifications or substitutions should be covered within the scope of the claims of this utility model.
