[0023] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.
[0024] Reference Figure 1 、 Figure 6 , an embodiment provided by the utility model:
[0025] The first connecting portion 2 is fixedly sleeved on one side of the tube body 1, and the second connecting portion 3 is fixedly sleeved on the other side of the tube body 1. A rubber ring 4 is fixedly provided at one end of the tube body 1. The tube body 1 includes a base layer 101, and a heat-insulating layer 102 is fixedly sleeved around the base layer 101. The heat-insulating layer 102 is fixedly sleeved around the protective layer 103.
[0026] Specifically, by arranging the No. 1 connection part 2 and the No. 2 connection part 3 on both sides of the pipe body 1, the No. 1 connection part 2 and the No. 2 connection part 3 can quickly splice the multi-section pipe body 1, and by arranging the rubber ring 4, the sealing effect of the pipe after splicing can be improved. By arranging the thermal insulation layer 102, the thermal insulation layer 102 is set to butyl rubber. Butyl rubber can have a thermal insulation effect while also having good waterproof performance and chemical corrosion resistance. It is suitable for pipe insulation that requires long-term durability. A protective layer 103 is arranged around the thermal insulation layer 102, and the protective layer 103 is set to a plastic sheath to protect the thermal insulation layer 102.
[0027] Reference Figure 2 、 Figure 3An antifreeze aluminum tube includes a tube body 1, a No. 1 connecting part 2 and a No. 2 connecting part 3. The No. 1 connecting part 2 includes a No. 1 collar 201. An annular groove 202 is formed on the end of the No. 1 collar 201 away from the No. 2 connecting part 3. Slots 204 are formed on the inner walls of the upper and lower sides of the annular groove 202. Limiting grooves 203 are formed on both the front and rear sides of the end of the No. 1 collar 201 away from the No. 2 connecting part 3.
[0028] Specifically, by setting the No. 1 connection part 2 and inserting the No. 2 connection part 3 into the No. 1 connection part 2, the two sections of the pipe can be fixed. By setting the limit groove 203, the limit block 314 can be inserted into the limit groove 203 during splicing, and positioning can be performed during splicing, so that the insert block 304 can be inserted into the slot 204.
[0029] Reference Figure 2 、 Figure 3 、 Figure 4 、 Figure 5 The second connecting part 3 includes a No. 2 collar 301, two connecting plates 303 and a rotating sleeve 307. An inner groove 302 is provided inside the No. 2 collar 301. A pressure block 305 is fixedly provided at one side of the opposite ends of the two connecting plates 303. An insert block 304 is fixedly provided at the other side of the opposite ends of the two connecting plates 303. Two No. 1 springs 306 are fixedly provided at the opposite ends of the two connecting plates 303 on one side of the pressure block 305. An oblique groove 309 is provided on the upper and lower inner walls of the rotating sleeve 307. A groove 308 is provided on the opposite side of the upper and lower inner walls of the rotating sleeve 307. A No. 2 spring 310 is fixedly provided on the inner wall on the opposite side of the two grooves 308. A fixing plate 313 is fixedly provided on the upper and lower opposite sides of the No. 2 collar 301.
[0030] An L-shaped plate 311 is fixedly provided on the upper part of the rotating sleeve 307 near the side of the No. 1 connecting part 2, and a fixed block 312 is fixedly provided on the upper part of the No. 2 ring 301 near the end of the No. 1 connecting part 2. The L-shaped plate 311 and the fixed block 312 are fixed by bolts. Limiting blocks 314 are fixedly provided on the front and rear ends of the No. 2 ring 301. The two insert blocks 304 and the pressure block 305 all pass through the No. 2 ring 301. The rotating sleeve 307 and the No. 2 ring 301 are rotatably sleeved. The two No. 2 springs 310 are fixedly connected to the two fixed plates 313 respectively, and the two pressure blocks 305 respectively pass through the inside of the two inclined grooves 309.
[0031] Specifically, by setting a pressure block 305, the pressure block 305 and the plug block 304 are connected by the connecting plate 303. When the pressure block 305 is pressed, the connecting plate 303 drives the plug block 304 to move downward, thereby separating the two spliced pipe sections. By setting a No. 1 spring 306, the connecting plate 303 always maintains the force that drives the plug block 304 toward the slot 204. After the connecting plate 303 is pressed, the No. 1 spring 306 can drive it to reset. By setting a rotating sleeve 307 and a No. 2 collar 301 for rotation, a groove 308 is set in the rotating sleeve 307 and a No. 2 spring is set in the groove 308. The second spring 310 is connected to the fixing plate 313 connected to the second collar 301 after the rotating sleeve 307 is rotated, thereby compressing the second spring 310, so that it can be reset after the rotating sleeve 307 is released. After the rotating sleeve 307 is rotated, the pressing block 305 can be compressed to drive the connecting plate 303 and the insert block 304 to move into the inner groove 302, so that the two sections of the tube body 1 can be disassembled. By setting the L-shaped plate 311 and the fixing block 312 and fixing them with bolts, the rotating sleeve 307 can be restricted, thereby preventing the rotating sleeve 307 from being accidentally rotated and causing the two tube bodies 1 to be disassembled.
[0032] Working principle: When the pipe is used to splice multiple sections of pipes, the second connecting part 3 at one end of one of the aluminum pipes is inserted into the first connecting part 2, so that the two limiting blocks 314 and the two limiting slots 203 are inserted into each other. Since the opposite ends of the two inserting blocks 304 are set as inclined surfaces, the two inserting blocks 304 can be inserted into the slots 204 when the two pipes are inserted together, thus completing the rapid splicing of multiple sections of aluminum pipes.
[0033] When disassembling the two sections of aluminum tube, the bolts fixing the L-shaped plate 311 and the fixing block 312 can be removed. Since the opposite sides of the two pressing blocks 305 are set as inclined surfaces, the inclined groove 309 can be rotated away from the entire body of the pressing block 305 by rotating the rotating sleeve 307, and the pressing block 305 can be pressed. The pressing block 305 drives the connecting plate 303 and the insert block 304 to move toward the inside of the inner groove 302, and the two sections of the tube body 1 can be disassembled.
[0034] Next, an insulation layer 102 is provided around the pipe. The insulation layer 102 is made of butyl rubber. This butyl rubber not only provides thermal insulation but also has excellent waterproof and chemical corrosion resistance, making it suitable for pipe insulation requiring long-term durability. A protective layer 103 is provided to protect the insulation layer 102.
[0035] Finally, it should be noted that the above is only a preferred embodiment of the present invention and is not intended to limit the present invention. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art can still modify the technical solutions described in the aforementioned embodiments or make equivalent replacements for some of the technical features therein. Any modifications, equivalent replacements, improvements, etc. made within the spirit and principles of the present invention should be included in the scope of protection of the present invention.
