[0020] like Figure 1 and 2 As shown in FIG. 3 , in one embodiment, a tubing cleaning fixture is provided, the cleaning fixture comprising:

[0021] A fixture bracket 4 is used to position a number of oil pipes 5 to be cleaned. The fixture bracket 4 includes an upper top plate and a lower bottom plate. The upper top plate and the lower bottom plate are connected by a plurality of guide rods 8 to form a frame structure. The fixture bracket 4 also includes an oil pipe stopper 7 that is slidably fitted on the guide rods 8. The oil pipe stopper 7 is used to cooperate with the bottom end surface of the oil pipe 5 to be cleaned.

[0022] The nozzle box 11 is provided with a plurality of independently controllable cleaning nozzles 1, and the cleaning nozzles 1 are connected with the oil pipe 5 to be cleaned through the through holes 10 provided on the upper top plate, so that the cleaning nozzles 1 can pass the cleaning liquid into the oil pipe 5 to be cleaned.

[0023] When the embodiment of the utility model is actually used, the oil pipe 5 to be cleaned is placed on the clamp bracket 4 in sequence, the head end of the oil pipe 5 to be cleaned is abutted against the upper top plate, and the position of the oil pipe stopper 7 is adjusted so that the bottom end surface of the oil pipe 5 to be cleaned is abutted against the oil pipe stopper 7, so that the oil pipe 5 to be cleaned is fixed. Here, in this embodiment, the position adjustment or locking of the oil pipe stopper 7 can be achieved by the adjusting nut 6 matched thereon, and then, the cleaning liquid is introduced into the corresponding oil pipe 5 to be cleaned through the cleaning nozzle 1, and the cleaning liquid can flow out from the through hole 10 opened on the oil pipe stopper 7.
