The position adjustment structure 4 includes a fixing strip 41, which is formed on both sides of the fixing groove 3. A T-shaped groove 42 is formed inside the fixing strip 41, and a sliding block 43 is provided inside the T-shaped groove 42. The two side walls of the sliding block 43 are provided with mating grooves 44, and the mating grooves 44 of the sliding block 43 are slidably connected to the inside of the T-shaped groove 42. A clamping structure 5 is provided in the middle of the sliding block 43. By sliding the sliding block 43 inside the T-shaped groove 42, the clamping structure 5 can be moved to a suitable position, thereby aligning the clamping structure 5 with metal pipes at different positions. Even when there are large errors in the processing, the copper pipe will be fixed.

[0027] In this embodiment, bolts are provided at both ends of the fixing strip 41, and the two ends of the fixing strip 41 are fixed to the outer shell 1 of the refrigeration unit by the bolts.

[0028] In this embodiment, a reserved groove 45 is provided on the surface of the fixing strip 41 and at both ends of the T-shaped groove 42. The size of the reserved groove 45 is greater than or equal to the size of the sliding block 43. The number of sliding blocks 43 is increased or decreased according to the length or number of metal pipes of the refrigeration unit to ensure that there are enough to fix the metal pipes.

[0029] In this embodiment, the sliding block 43 has a threaded hole in the middle, and a screw is provided inside the threaded hole. The bottom end of the clamping structure 5 is fixed to the sliding block 43 by the screw, so that the direction of the copper tube is the same as the direction of the fixing hole 54.

[0030] In this embodiment, the clamping structure 5 includes several layers of first fixing blocks 51, second fixing blocks 52, and third fixing blocks 53. The second fixing blocks 52 and third fixing blocks 53 are located on both sides of the first fixing block 51. Fixing holes 54 are provided at the joints of adjacent layers of first fixing blocks 51, adjacent layers of second fixing blocks 52, and adjacent layers of third fixing blocks 53. A connecting strip 55 is provided between each layer of first fixing blocks 51, second fixing blocks 52, and third fixing blocks 53. The number of fixing blocks can be increased according to the height of the metal tube from the sliding block 43. The fixing blocks support metal tubes at different distances. The metal tubes can also be clamped by the inside of the fixing holes 54 or the superior arc segment of the fixing holes 54 to prevent the metal tubes from loosening when the car shakes greatly.

[0031] In this embodiment, the connecting strip 55 passes through the interior of the first fixing block 51, the second fixing block 52 and the third fixing block 53, and the two ends of the connecting strip 55 are interference-fitted with the interior of the second fixing block 52 and the third fixing block 53, which can change the distance between the fixing blocks on both sides of the first fixing block 51, so that the metal tube inside the refrigeration unit is aligned with the fixing hole 54, and the metal tube can be fastened to the interior of the fixing hole 54.

[0032] In this embodiment, the fixing holes 54 located at the upper ends of the first fixing block 51, the second fixing block 52, and the third fixing block 53 are of a superior arc, and the fixing holes 54 located at the lower ends of the first fixing block 51, the second fixing block 52, and the third fixing block 53 are of a inferior arc. A clamping block 56 and a clamping groove 57 are provided between the first fixing blocks 51 of adjacent layers. The clamping block 56 is located on the lower surface of the first fixing block 51, and the clamping groove 57 is located on the upper surface of the first fixing block 51. The copper tube can be fixed through the entire fixing hole 54, or it can be fixed through the superior arc-shaped fixing hole 54.

[0033] It should be noted that the interior of the refrigeration unit casing 1 consists of a compressor, condenser, liquid receiver dryer, expansion valve, evaporator, and blower. Copper pipes and high-pressure rubber hoses are used to connect the components into a closed system. The position of the copper pipes or metal pipes can be fixed by the position adjustment structure 4 inside the refrigeration unit casing 1. Specifically, a fixing groove 3 is provided where the copper pipes are arranged densely, and the position adjustment structure 4 is installed inside the fixing groove 3. The sliding block 43 can slide along the inside of the T-slot 42. As needed, the sliding block 43 can be inserted into or removed from the reserved groove 45. At this time, the position of the sliding block 43 can be moved according to the position of the copper pipe, so that the sliding block 43 is aligned with the copper pipe. The locking structure 5 is connected to the sliding block 43 by screws. The locking structure 5 can be rotated slightly to adapt to the direction of the copper pipe. At this time, the position of the locking structure 5 is adjusted according to the distance between the copper pipe and the sliding block 43. Block 56 and locking groove 57 are locked together. Different numbers of first fixing blocks 51 can be locked onto the surface of the first fixing block 51, so that the distance between the first fixing block 51 and the copper pipe is adapted. When the copper pipe and the first fixing block 51 are located on one side of the first fixing block 51, the second fixing block 52 or the third fixing block 53 can be inserted into the connecting strip 55. Since the two ends of the connecting strip 55 are interference-fitted with the interior of the second fixing block 52 and the third fixing block 53, it can be ensured that the fixing blocks will not fall off when inserted into the two ends of the connecting strip 55. When assembling the various components and copper pipes inside the refrigeration unit housing 1, the copper pipe is locked into the fixing hole 54 at the first fixing block 51. Alternatively, the fixing holes 54 of the second fixing block 52 and the third fixing block 53 can be used to fasten the copper pipe. The circular fixing hole 54 and the arc shape of the fixing hole 54 fix the copper pipe. Later, when the car is running or the car shakes a lot, the copper pipe can be securely connected, further preventing the airflow leakage of various components.
