[0024] refer to Figure 1 、 Figure 2 and Figure 3 The locking assembly 41 includes a rotating ring 411, a fixed block 412, a pin block 413 and a handle 414. The rotating ring 411 is sleeved on the surface of the tube body 1 and is rotatably connected to the tube body 1. There are four fixed blocks 412, which are evenly fixedly connected to the outside of the rotating ring 411. There are four pin blocks 413, which are fixedly connected to one side of the four fixed blocks 412. The positions of the four pin blocks 413 correspond to the positions of the four connecting members 43. The handle 414 is fixedly connected to the left surface of the rotating ring 411.

[0025] The above solution is adopted: by providing a locking assembly 41 to pin the connector 43 fixedly connected to the rear surface of the mounting cover 3, thereby facilitating quick disassembly and assembly of the mounting cover 3 when replacing and repairing the internal cooling pipe.

[0026] refer to Figure 2 、 Figure 3 and Figure 4 The positioning assembly 42 includes a box body 421, a moving rod 422, a push plate 423, a push spring 424, a clamp 425 and a pull button 426. The box body 421 is fixedly connected to the left surface of the tube body 1. There are two moving rods 422, which are respectively arranged at the left and right ends of the box body 421. The front and rear ends of the two moving rods 422 are respectively fixedly connected to the front and rear surfaces of the box body 421. The push plate 423 is sleeved on the front end surface of the two moving rods 422 and is connected to the two moving rods 422. Sliding connection, there are two push springs 424, which are respectively arranged on the surfaces of the two moving rods 422, and the front and rear ends of the two push springs 424 are fixedly connected to the rear surface of the push plate 423 and the inner rear surface of the box body 421 respectively. The clamping head 425 is fixedly connected to the front surface of the push plate 423, and the front end extends out of the box body 421 and is slidingly connected to the box body 421. The pull button 426 is fixedly connected to the lower end of the left surface of the push plate 423, and the left end extends out of the box body 421 and is slidingly connected to the box body 421.

[0027] The above solution is adopted: by setting a positioning component 42 to position and fix the locking component 41, after the locking component 41 fixes the installation cover 3, the locking component 41 is fixed to prevent the locking component 41 from rotating due to its looseness.

[0028] refer to Figure 2 、 Figure 3 and Figure 4 A positioning groove 5 is provided on the rear surface of the rotating ring 411 in front of the clamping head 425 , and the positions of the positioning groove 5 and the clamping head 425 correspond to each other.

[0029] The above solution is adopted: by providing a positioning groove 5 on the rear surface of the rotating ring 411 to cooperate with the positioning assembly 42 to fix the rotating ring 411.

[0030] refer to Figure 1 and Figure 2 Four connecting grooves 6 are evenly opened around the surface of the front and rear ends of the tube body 1. The connecting grooves 6 pass through the tube body 1. The positions of the connecting grooves 6 correspond to the positions of the pin blocks 413.

[0031] The above solution is adopted: by evenly opening four connecting grooves 6 around the front and rear ends of the tube body 1 to match the four connecting parts 43, the installation cover 3 is connected and positioned, which facilitates the locking assembly 41 to fix the connecting parts 43.

[0032] refer to Figure 1 and Figure 2 The connecting member 43 includes a connecting head 431 and a pin groove 432. The connecting head 431 is arranged in the connecting groove 6 and is movably connected to the connecting groove 6. The connecting groove 6 is extended from the front and rear ends of the connecting head 431. The front end of the connecting head 431 is fixedly connected to the rear surface of the mounting cover 3. The pin groove 432 is opened on one side surface of the connecting head 431 and passes through the connecting head 431. The position of the pin groove 432 corresponds to the position of the pin block 413.

[0033] The above solution is adopted: by providing a connecting member 43 to cooperate with the connecting groove 6 to connect and position the installation cover 3, and to cooperate with the locking assembly 41 to fix it, thereby fixing the installation cover 3.

[0034] After the cooling pipe and other parts inside the tube body 1 are replaced and repaired, when fixing the mounting cover 3, the connector 431 is inserted into the connecting groove 6, and then the rotating ring 411 is rotated by the handle 414. The rotating ring 411 rotates while driving the fixing block 412 to rotate. The fixing block 412 rotates and drives the pin block 413 to be inserted into the pin groove 432. When the pin block 413 is inserted into the pin groove 432, the inner wall of the pin groove 432 is squeezed to a certain extent, so that the mounting cover 3 fits tightly against the tube body 1 backward, and the sealing ring in the tube body 1 is further compressed to seal. After the pin block 413 is completely rotated and inserted into the pin groove 432, the position of the positioning groove 5 is rotated to correspond to the clamping head 425, and the push spring 424 pushes the push plate 423 forward, so that the push plate 423 moves on the moving rod 422. The surface moves forward, and at the same time drives the clamping head 425 to move forward and insert into the positioning groove 5, positioning and fixing the rotating ring 411, thereby completing the replacement and fixing work. When replacing and repairing the cooling pipe and its parts inside the tube body 1, when removing the mounting cover 3, the push plate 423 is pulled backward on the surface of the moving rod 422 by the pull button 426, and the push spring 424 is compressed at the same time, and the push plate 423 drives the clamping head 425 to move out of the positioning groove 5, releasing the fixation of the rotating ring 411, and rotating the rotating ring 411 in the opposite direction by the handle 414. The rotating ring 411 rotates and drives the fixing block 412 to rotate and turn the pin block 413 out of the pin groove 432 to release the fixation of the connecting member 43, and then pull the mounting cover 3 forward to pull the connecting member 43 out of the connecting groove 6, thereby completing the disassembly.

[0035] To sum up: the cooler uses a quick-change assembly, which solves the problem that the mounting cover of the existing tubular cooler is usually fixed with multiple bolts, so that during the disassembly and assembly during the replacement of the cooling pipe, it is necessary to repeatedly use tools to tighten the bolts, which is more troublesome, making it inconvenient to quickly replace and affecting work efficiency.
