[0002] The ventilation pipes are mainly steam-water pipes, and the function of the pipes is to change the living environment, including the pipes in the boiler room, the air-conditioning equipment machine room, the heating external network, the indoor heating pipes, and the air-conditioning water pipes. The most common consumables in the heating ventilation and air conditioning project are the heating ventilation and air conditioning pipes. The heating ventilation and air conditioning pipes are composed of multiple groups of through pipes, and fixing parts are installed between two groups of through pipes for fixation. The fixing parts need to have sealing performance to prevent the transported gas from overflowing.

[0003] Some heating ventilation and air conditioning pipes need to be buried underground, and the fixing parts are connected to the pipes through metal nuts and bolts. Because the bolts and nuts are exposed to the air for a long time, they are prone to moisture and corrosion, which will inconvenience the staff to disassemble and maintain them, and leakage will occur. Moreover, the strength of the pipe connection is weaker than that of the complete pipe. After being subjected to pressure, the connection of the heating ventilation and air conditioning pipe will crack or break, causing air leakage or water leakage in the heating ventilation and air conditioning pipe, bringing trouble to the users.

The fixed sleeve 303 is fixedly installed on the second pipeline 2 and is communicated; an external thread 305 is arranged outside the connection sleeve 301, and an internal thread 304 is arranged inside the installation sleeve 302. Connect the connection sleeve 301 and the fixed sleeve 303 together, and then move the installation sleeve 302 to connect the installation sleeve 302 to the fixed sleeve 303 through the internal and external threads, thereby connecting and fixing the connection sleeve 301 and the fixed sleeve 303 together.

[0027] The reinforcing component 4 includes clamping rods 401 arranged on the outer side of the connecting sleeve 301. There are several clamping rods 401, which are fixedly installed on the connecting sleeve 301 in an annular array. A through hole is arranged inside the clamping rod 401, and a clamping groove 402 is arranged inside the fixed sleeve 303. The clamping groove 402 is opened on the fixed sleeve 303, and the quantity and position correspond to those of the clamping rod 401. The size of the clamping groove 402 allows the clamping rod 401 to slide inside it. A limiting rod 403 is arranged inside the clamping groove 402. The limiting rod 403 is inserted into the fixed sleeve 303. A spring 404 is arranged on the outer side of the limiting rod 403. The spring 404 is sleeved on the outer side of the limiting rod 403 and is limited between the fixed sleeve 303 and the limiting rod 403. The connecting sleeve 301 drives the clamping rod 401 to be inserted into the clamping groove 402 of the fixed sleeve 303, and then the connecting sleeve 301 is rotated to make the clamping rod 401 push up the limiting rod 403 and the spring 404 until the clamping rod 401 moves to the edge of the clamping groove 402 and the limiting rod 403 is clamped into the through hole on the clamping rod 401. The spring 404 resets to limit the limiting rod 403 in the clamping rod 401. By limiting the clamping rod 401, the connecting sleeve 301 is limited on the fixed sleeve 303.

[0028] A connecting rod 5 is arranged on the outer side of the limiting rod 403. The connecting rod 5 is inserted into the top of the limiting rod 403. A pressing rod 6 is arranged on the outer side of the connecting rod 5. The pressing rod 6 is fixedly installed on the top of the connecting rod 5, and an inclined mouth is arranged on one side of the pressing rod 6. By pressing down the pressing rod 6, the connecting rod 5 is driven to move downwards to exert pressure on the limiting rod 403, improving the firmness between the limiting rod 403 and the clamping rod 401; A clamping ring 7 is arranged inside the mounting sleeve 302. The clamping ring 7 is fixedly installed at one end inside the mounting sleeve 302. A fixing ring 8 is arranged on the outer side of the fixed sleeve 303. The fixing ring 8 is fixedly installed on the outer side of the fixed sleeve 303. A hexagonal block 9 is arranged on the outer side of the mounting sleeve 302. The hexagonal block 9 is fixedly installed on the outer side of the mounting sleeve 302. When the mounting sleeve 302 is moved, one side of the clamping ring 7 is driven to contact the side of the fixing ring 8 to limit the mounting sleeve 302. At the same time, a sealing ring is arranged on the clamping ring 7, which can improve the sealing performance between the mounting sleeve 302 and the connecting sleeve 301.

[0029] The supporting component 10 includes a connecting ring 1001 arranged on the outer sides of the first pipe 1 and the second pipe 2. Connecting rings 1001 are fixedly installed on both the first pipe 1 and the second pipe 2. A supporting rod 1002 is arranged inside the connecting ring 1001. The supporting rod 1002 is inserted into the connecting ring 1001. A limiting bolt 1003 is arranged inside the supporting rod 1002. The limiting bolt 1003 is installed in the supporting rod 1002. After the two pipes are connected, the mounting holes on the two connecting rings 1001 just correspond. At this time, the supporting rod 1002 is inserted into the two connecting rings 1001, and then the supporting rod 1002 is fixed by using the limiting bolt 1003. The supporting rod 1002 is used to support the connection part of the two pipes, improving the compressive performance of the pipe connection part.

[0030] Working principle: When connecting the HVAC pipes, the connecting sleeve 301 with the clamping rod 401 is inserted into the slot 402 of the fixed sleeve 303. Then, rotate the connecting sleeve 301 to make the clamping rod 401 push the limiting rod 403 and the spring 404 upward until the clamping rod 401 moves to the edge of the slot 402 and the limiting rod 403 is clamped into the through hole on the clamping rod 401. The spring 404 resets to limit the limiting rod 403 in the clamping rod 401. By limiting the clamping rod 401, the connecting sleeve 301 is limited on the fixed sleeve 303. Then, move the mounting sleeve 302 and connect the mounting sleeve 302 to the fixed sleeve 303 through internal and external threads, thus connecting and fixing the connecting sleeve 301 and the fixed sleeve 303 together. When the mounting sleeve 302 is installed, it presses down the pressure rod 6, and the pressure rod 6 drives the connecting rod 5 to move downward to exert pressure on the limiting rod 403, improving the firmness between the limiting rod 403 and the clamping rod 401. After the two pipes are connected, the mounting holes on the two connecting rings 1001 just correspond. At this time, insert the support rod 1002 into the two connecting rings 1001, and then fix the support rod 1002 with the limiting bolt 1003. Use the support rod 1002 to support the connection of the two pipes, improving the compressive performance of the pipe connection.
