Description

Technical Field

[0001] The utility model relates to the technical field of copper tubes, in particular to a combined tooth internal thread copper tube. Background Art

[0002] Internally threaded copper tube, also known as non-smooth tube, English name INNERGROOVEDCOPPERTUBE (IGT), refers to the internally threaded TP2 copper tube with a smooth outer surface and a certain number of regular threads on the inner surface. Compared with traditional copper tubes, its thermal conductivity is improved by 20 to 30 percent. With the world's energy shortage and the implementation of the domestic energy efficiency air conditioning access system, internally threaded copper tubes will be widely used in the air conditioning and refrigeration industry.

[0003] For example, the utility model with application number 202120555021.5 discloses a combined tooth internal thread copper tube. The utility model adds a step-like structure to some of the internal teeth, which increases the nucleation points of bubbles during the evaporation of the medium and improves the heat exchange efficiency. The tooth height and tooth width of ordinary teeth are greater than those of step-like teeth. During the copper tube expansion process, the step-like structure of the step-like teeth will be effectively protected. The step-like tooth structure can also reduce the mass of a single copper tube, which is conducive to saving resources and reducing costs.

[0004] Similar to the above application, there are still the following deficiencies:

[0005] Existing threaded copper pipes are prone to heat accumulation when heat circulates, causing the copper pipes to expand due to heat. At the same time, when the pipes are connected and combined for use, gaps are prone to appear at the joints, and leakage is prone to occur at the gaps. At the same time, water vapor in the external environment can easily damage the copper pipes through the gaps.

[0006] Therefore, in view of this, the existing structure and defects are studied and improved, and a combined tooth internal thread copper tube is proposed. Utility Model Content

[0007] The utility model aims to provide a combined tooth internal thread copper tube to solve the problems raised in the above background technology.

[0008] To achieve the above object, the utility model provides the following technical solutions: a combined tooth internal thread copper tube, comprising a copper tube body, the copper tube body comprising an outer tube, an inner heat conductive interlayer is installed inside the outer tube, an inner tube is arranged inside the inner heat conductive interlayer, the inner wall of the inner tube is equidistantly provided with inner teeth, and the outer surface of the inner teeth is equidistantly provided with protective teeth;

[0009] A connecting mechanism for connecting and assembling the copper tube bodies is arranged outside one end of the copper tube body.

[0010] Furthermore, the connection mechanism includes a rubber ring, which is sleeved on the outside of the copper tube body, and a tightening ring is arranged on the outside of the rubber ring. The gap is protected by the rubber ring and the tightening ring, so that the copper tube is not protected by the gap.

[0011] Furthermore, an external connector is installed at one end of the copper tube body, and an internal connector is installed at the other end of the copper tube body. The copper tube bodies are connected by the external connector and the internal connector.

[0012] Furthermore, the inner teeth are arranged as a threaded structure, and the inner teeth, the protective teeth and the copper tube body form an integrated structure. The heat can be diverted through the threaded structure of the inner teeth to protect the copper tube.

[0013] Furthermore, one end of the tightening ring is fixedly connected to an adjustment box, the other end of the tightening ring passes through the interior of the adjustment box, and the end of the tightening ring close to the center of the copper tube body is evenly distributed with adjustment teeth. The tightening ring can ensure that the rubber ring fits more closely with the outer surface of the copper tube.

[0014] Furthermore, the adjusting box is rotatably connected to a rotating rod inside, and rotating gears are evenly distributed outside the rotating rod, so that the rotating gears can be driven to rotate by the rotating rod.

[0015] Furthermore, the rotating gear and the adjusting teeth are meshed, and the tightening ring forms a local moving structure through the rotating gear and the adjusting teeth. Through the meshing structure of the rotating gear and the adjusting teeth, the tightening ring can move inside the adjusting box and tighten the rubber ring to ensure the protective effect of the rubber ring.

[0016] The utility model provides a combined tooth internal thread copper tube, which has the following beneficial effects:

[0017] The utility model connects the copper tube bodies through the setting of the connection mechanism, through the action of the external connection head and the internal connection head, and protects the connection from the outside through the rubber ring, so that the gap is blocked by the rubber ring, and the internal gas leakage and the penetration of external water vapor due to the action of the gap are avoided, thereby avoiding damage to the copper tube body. The threaded structure of the internal teeth can divert heat and reduce the damage caused by the heat to the copper tube body. The internal teeth are protected by the action of the protective teeth, and the service life of the internal teeth and the copper tube body is extended. BRIEF DESCRIPTION OF THE DRAWINGS
