Embodiment Construction
[0020] The present invention will be described in further detail below in conjunction with the accompanying drawings.
[0021] figure 1 A pipe correction device according to an embodiment of the present invention is schematically shown. As shown in the figure, the device includes a guide sleeve 1 and a rod that can be used together. Wherein, rod body comprises guide rod 2 and center rod 3, and one end of guide rod 2 is provided with stopper 22, and links to each other with one end of center rod 3, and the other end of guide rod 2 is provided with a guide head 21, and the outer surface of guide head 21 The diameter is smaller than the inner diameter of the guide sleeve 1, and the end of the guide head 21 is provided with a truncated cone-shaped insertion head 23, and the outer diameter of the insertion head 23 gradually decreases evenly along the end of the guide head 21. The guide rod 2 and the center rod 3 can be integrally formed or connected in a detachable manner such as...

The invention discloses a pipeline correcting device. The pipeline correcting device comprises a guide sleeve and a rod body which can be matched for use; the rod body comprises a guide rod and a centre rod; one end of the guide rod is connected with one end of the centre rod; a guide head is arranged at the other end of the guide rod; the outside diameter of the guide head is smaller than the inside diameter of the guide sleeve; an inserting head is arranged at the tail end of the guide head; the outside diameter of the inserting head becomes small gradually and uniformly along the tail end of the guide head; a limiting piece is also arranged on the guide rod; the limiting piece is positioned at a connecting position between the guide rod and the centre rod. The pipeline correcting device has the beneficial effects that when a pipe mouth of a pipeline is corrected by using the device, the guide sleeve is arranged outside the pipe mouth in a sleeving manner, and then the guide rod is inserted into the pipe mouth. Both the guide sleeve and the guide head are made of a material with high rigidity and high hardness; the pipeline is clamped between the guide sleeve and the guide head; a deformed pipe mouth is easy to recover and does not rebound easily; when the guide head is inserted at a suitable position of the pipe mouth, the limiting piece is kept at the pipe moth so that the guide rod can be prevented from moving continuously, and the guide head is convenient to withdraw.
Description
technical field [0001] The invention relates to the field of pipeline correction, in particular to a pipeline correction device for circular pipelines in air conditioners. Background technique [0002] With the development of science and technology and the improvement of people's living standards, air conditioners are not only used in public places, but also in thousands of families. When the air conditioner is working, it generally uses the state change of the internal refrigerant and the thermal cycle to cool or heat the closed space. Therefore, the air conditioner is equipped with multiple pipes to transport the hot and cold media. In order to save space and transportation costs, before purchasing the air conditioner, the manufacturer manages and stores all the components of the air conditioner in a unified manner. After the customer purchases the air conditioner, the installer installs the air conditioner. These pipes used in air conditioners are generally made of coppe...
