Abstract
The utility model discloses a cooling tube hookup assembly, including the inflation nut that is equipped with the hole, with inflation nut rear end associative inlet tube, its characterized in that the external screw thread of inflation nut through its middle section is associative with cap nut, and the anterior segment of inflation nut is equipped with the continuous outer circular conical surface and the face of cylinder, and the back end of bronze medal pipe is between the outer circular conical surface and the face of cylinder of the hole that radially lies in cap nut and inflation nut, and the back end of copper pipe is equipped with and expand outer circular conical surface and the face of cylinder assorted internal cone face and the hole of nut. The utility model has the advantages of equipment convenient operation, good, the long service life of leakproofness.
Description
Technical field
This utility model relates to a kind of cooling tube and couples assembly.
Background technology
Existing cooling tube couples assembly and generally includes by two joints of thread connection, the pipe fitting that is connected with respective joint, prevent leakage, improve sealing, the sealing ring of quality of rubber materials need to be set in two joints, it is the most relatively complicated that it assembles location, operation inconvenience, and sealing ring is easy to wear, its service life is the shortest, leakage can be produced after after inefficacy, need to again change, have impact on the service life of assembly.
Summary of the invention
The purpose of this utility model is for deficiencies of the prior art, it is provided that a kind of cooling tube couples assembly, and it has assembly operation convenience, good airproof performance, the advantage of length in service life.
For reaching above-mentioned purpose, a kind of cooling tube of the present utility model couples assembly, the water inlet pipe being connected with expansion nut rear end including the expansion nut being provided with endoporus, it is characterized in that described expansion nut is connected with cap nut by the external screw thread in its stage casing, the leading portion of expansion nut is provided with connected outer conical surface and the face of cylinder, the back segment of one copper pipe between outer conical surface and the face of cylinder of the endoporus and expansion nut that are radially disposed in cap nut, the back segment of copper pipe is provided with the outer conical surface with expansion nut and the face of cylinder matches internal conical surface and endoporus.
When this utility model assembles, while it is coupled by rotation expansion nut with cap nut, the leading portion outer conical surface of expansion nut enters the endoporus of copper pipe, makes it deform outwardly against copper pipe inwall, until the outer conical surface of copper pipe cladding expansion nut leading portion and the face of cylinder, it is achieved couple, seal dual-use function；This utility model is due to the sealing ring without quality of rubber materials, and not only assembly operation is convenient, and expansion nut forms sealing surface with copper pipe by crimp, and sealing area is big, and sealing reliability is greatly improved, and without consumable accessory, service life is long；The expansion nut leading portion endoporus of this structure, less than the endoporus of copper pipe, aerosolizable cooling water, improves heat exchange efficiency；
As further improvement of the utility model, expansion nut is provided with the positioning step being positioned at external screw thread rear, stage casing；Expansion nut axially can be positioned during assembling, improve packaging efficiency further；
In sum, this utility model has assembly operation convenience, good airproof performance, length in service life, advantage that heat exchange efficiency is high.
Accompanying drawing explanation
Fig. 1 is the front view of this utility model embodiment.
Detailed description of the invention
Below in conjunction with the accompanying drawings this utility model is described in further detail.
As shown in Figure 1, a kind of cooling tube couples assembly, including the expansion nut 2 being provided with endoporus, the water inlet pipe 1 being connected by screw thread with expansion nut 2 rear end, expansion nut 2 is connected with cap nut 3 by the external screw thread 2c in its stage casing, expansion nut 2 is provided with the step 2d being positioned at external screw thread 2c rear, stage casing, the leading portion of expansion nut 2 is provided with connected outer conical surface 2a and face of cylinder 2b, the back segment of one copper pipe 4 is being radially disposed between the endoporus of cap nut 3 and outer conical surface 2a of expansion nut 2 and face of cylinder 2b, the back segment of copper pipe 4 is provided with outer conical surface 2a with expansion nut and face of cylinder 2b matches internal conical surface and endoporus.
When this utility model assembles, while it is coupled by rotation expansion nut 2 with cap nut 3, leading portion outer conical surface 2a of expansion nut 2 enters the endoporus of copper pipe 4, makes it deform outwardly against copper pipe inwall, until step 2d is close to the rear end face of cap nut 3, now copper pipe 4 is coated with outer conical surface 2a and the face of cylinder 2b of expansion nut 2 leading portion, copper pipe 4 is fixed between the endoporus of cap nut 3 and outer conical surface 2a of expansion nut 2 and face of cylinder 2b, it is achieved couples, seal dual-use function；This utility model is due to the sealing ring without quality of rubber materials, and not only assembly operation is convenient, and expansion nut 2 forms sealing surface with copper pipe 4 by crimp, and sealing area is big, and sealing reliability is greatly improved, and also without consumable accessory, service life is long；The expansion nut 2 leading portion endoporus of this structure, less than the endoporus of copper pipe 4, the aerosolizable cooling water when injection, improves heat exchange efficiency；Assembling can axially be positioned by step 2d, improves packaging efficiency further.
