[0025] See also Figures 1-4 As shown, a hot water pipe circulation pump that is easy to disassemble includes a pump body 1, a heat dissipation cover 101 is fixedly installed on the upper surface of the pump body 1, a junction box 102 is fixedly installed at the middle part of the front end of the outer surface of the pump body 1, a fixing seat 103 is fixedly installed on the lower surface of the pump body 1, and a water inlet 2 and a water outlet 3 are fixedly provided at the lower parts of both sides of the outer surface of the pump body 1, and a metal hose 4 is fixedly provided at the ends of the water inlet 2 and the water outlet 3 away from the pump body 1;

[0026] The other end of the metal hose 4 is fixed with a first adapter 401. The outer surface of the other end of the first adapter 401 is provided with a docking groove 402. The middle of the upper and lower surfaces of the first adapter 401 are both provided with a semi-arc-shaped locking opening 403.

[0027] The first adapter 401 is screwed onto the inner surface of the docking groove 402 to install a docking block 501. The inner surface of the docking groove 402 and the inner and outer surfaces of the docking block 501 are provided with matching threads. The end of the docking block 501 away from the first adapter 401 is fixed with a second adapter 5. Several sealing rings 503 are fixed on the inner surface of the second adapter 5. Semi-arc-shaped limit openings 502 are opened in the middle of the upper and lower surfaces of the docking block 501.

[0028] The first adapter 401 is embedded and fixed with a locking ring 6 through the inner surface of the locking opening 403. The inner ring surface of the locking ring 6 is fixed with a protruding limit block 601, and the limit block 601 is embedded and installed in the limit opening 502. Connecting ears are fixed at both ends of the locking ring 6. The locking ring 6 is screwed and installed with a locking bolt 602 through the upper surface of the connecting ears.

[0029] When the present invention is in use, the pump body 1 can first be fixedly installed at a suitable position between the delivery pipes. At this time, the metal hoses 4 provided at the water inlet 2 and the water outlet 3 can be twisted to adjust the connection position of the water inlet 2 and the water outlet 3. While adjusting the connection position, the second adapter 5 spirally inserted in the first adapter 401 provided at the other end of the metal hose 4 can be screwed out, and the second adapter 5 can be tightly connected and sleeved onto the outer surface of the end of the delivery pipe. At this time, the first adapter 401 at the other end of the metal hose 4 can be adjusted to a state where it is connected to the end of the delivery pipe.

[0030] Secondly, after the first adapter 401 is connected to the conveying pipe, the second adapter 5 sleeved on the outer surface of the end of the conveying pipe can be controlled to move toward the first adapter 401, and the docking block 501 provided on the end of the second adapter 5 can be screwed into the docking groove 402 opened at the end of the first adapter 401, thereby completing the airtight connection between the second adapter 5 and the first adapter 401, and then completing the airtight connection between the conveying pipe and the metal hose 4. At this time, the locking ring 6 can be embedded and installed in the locking opening 403 opened on the outer surface of the first adapter 401, and the limiting block 601 provided on the inner ring surface of the locking ring 6 can be embedded in the limiting opening 502 opened on the outer surface of the docking block 501. In this case, the locking bolt 602 is used to lock and fix the locking ring 6, so that the second adapter 5 and the first adapter 401 can be locked and fixed to prevent separation;

[0031] Finally, when disassembling the pump body 1, it is only necessary to separate the locking ring 6 from the first adapter 401. At this time, the second adapter 5 can be separated from the first adapter 401 by screwing the docking block 501 out of the docking groove 402, thereby separating the metal hose 4 and the conveying pipe from each other, and completing the disassembly of the pump body 1.
