Description

Technical Field

[0001] This utility model relates to the field of copper tube drawing technology, specifically a copper shavings blowing device for the inner wall of an internally threaded mosquito coil tube. Background Technology

[0002] Internally threaded mosquito coil coils and straight pipes are used in the connection pipes of two devices and large refrigeration units. After the copper pipes are spun into teeth and sawn, copper shavings and burrs appear at the pipe openings, which cannot be completely cleaned and affect the connection effect of the pipes.

[0003] Based on the existing design of the copper shavings blowing device for the inner wall of the internally threaded mosquito coil tube, the toothed shape on the inner wall of the internally threaded copper tube results in significant resistance when compressed air blows out the copper shavings. Currently, blowing from both ends into the tube easily causes copper shavings to enter the middle of the tube, making it impossible to thoroughly clean the copper shavings. Therefore, its structure needs to be improved.

[0004] Now, a novel copper shavings blowing device for the inner wall of an internally threaded mosquito coil is proposed to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a copper shavings blowing device for the inner wall of an internally threaded mosquito coil tube, so as to solve the problem mentioned in the background art that copper shavings are easily caused to enter the middle of the copper tube and cannot be thoroughly cleaned.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a copper shavings blowing device for the inner wall of an internally threaded mosquito coil tube, comprising a first copper tube and an internally threaded mounting head, wherein the internally threaded mounting head is fixedly connected to the left side of the outer side of the first copper tube, a second copper tube is provided on the right side of the first copper tube, a blowing hole is provided on the outer side of the second copper tube, and a connecting seat is fixedly connected to the left side of the second copper tube.

[0007] As a further technical solution of this utility model, the purging holes are arranged in three rows, with three holes in each row.

[0008] As a further technical solution of this utility model, an installation groove is provided inside the right side of the first copper tube, an external thread is provided on the outside of the connecting seat, and an internal thread is provided on the inner wall of the installation groove. The first copper tube and the second copper tube are detachable through the connecting seat.

[0009] As a further technical solution of this utility model, a fixing block is provided on the left side of the internal thread mounting head, and a connecting block is fixedly connected to the right side of the fixing block. The connecting block is embedded in the interior of one side of the internal thread mounting head and is detachable.

[0010] As a further technical solution of this utility model, the purging hole is 30-60°.

[0011] As a further technical solution of this utility model, the diameter of the purging holes is 1.5-3.5mm, each row is evenly distributed along the circumference, and the angle between two rows is 90-120°.

[0012] Compared with the prior art, the beneficial effects of this utility model are: the copper shavings blowing device on the inner wall of the internal thread mosquito coil tube not only removes all copper shavings around the copper tube and facilitates the quick assembly of the two sets of tubes, but also prevents larger particles from entering the tube when not in use.

[0013] (1) By setting up a blow hole and changing the tilt angle of the blow hole, compressed air can be directly blown to the root of copper shavings. By setting 3-4 rows of blow holes in the circumference, with 2-3 blow holes in each row and each blow hole diameter of 1.5-3.5mm, and each row is distributed at 90-120°, all copper shavings in the circumference of the copper tube can be removed. By changing the hollow straight-through blow rod to a hollow side-through blow rod, the airflow direction is changed, and copper shavings are blown outward from the inner wall of the copper tube, thus eliminating the defect of copper shavings being blown into the inner cavity of the copper tube.

[0014] (2) By setting a first copper pipe and a second copper pipe, the first copper pipe has an installation groove on the inside of its right side, the connector has an external thread on its outside and an internal thread on the inner wall of the installation groove. The first copper pipe and the second copper pipe are detachable through the connector. During assembly, the connector on one side of the second copper pipe can be screwed into the first copper pipe, which makes it easy to quickly assemble and disassemble the two sets of pipes and to clean the inside of the two sets of pipes.

[0015] (3) By setting an internal threaded mounting head, a first copper tube, a fixing block, and a connecting block, the fixing block is set on the left side of the internal threaded mounting head, and the connecting block is fixedly connected to the right side of the fixing block. The connecting block is embedded in the interior of one side of the internal threaded mounting head and is detachable. When not in use, the connecting block can be snapped into the internal threaded mounting head to cover the internal threaded mounting head and prevent larger particles from entering the interior and clogging the tube.

The internally threaded mounting head 2 is fixedly connected to the left side of the outside of the first copper tube 1. A second copper tube 6 is provided on the right side of the first copper tube 1. A blowing hole 7 is provided on the outside of the second copper tube 6. A connecting seat 5 is fixedly connected to the left side of the second copper tube 6.

[0023] The purge holes 7 are arranged in three rows, with three holes in each row, and the purge holes 7 are at an angle of 30-60°.

[0024] The diameter of the purge holes 7 is 1.5-3.5mm, and they are evenly distributed in each row along the circumference, with an angle of 90-120° between the two rows;

[0025] Specifically, such as Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, by changing the tilt angle of the blow hole 7, compressed air can be directly blown to the root of the copper shavings. By setting 3-4 rows of blow holes around the circumference, with 2-3 blow holes in each row and each blow hole having a diameter of 1.5-3.5mm, and each row being distributed at 90-120°, all copper shavings around the copper tube can be removed. By changing the hollow straight-through blow rod to a hollow side-through blow rod, the airflow direction is changed, and copper shavings are blown from the inner wall of the copper tube outward, eliminating the defect of copper shavings being blown into the inner cavity of the copper tube.

[0026] The first copper tube 1 has an internal mounting groove 4 on the right side, the connector 5 has an external thread on the outside, and the mounting groove 4 has an internal thread on the inner wall. The first copper tube 1 and the second copper tube 6 can be detached through the connector 5.

[0027] Specifically, such as Figure 1 , Figure 3 and Figure 4 As shown, during assembly, the connecting seat 5 on one side of the second copper tube 6 can be screwed into the first copper tube 1, which facilitates quick assembly and disassembly of the two sets of tubes and makes it easy to clean the inside of the two sets of tubes.

[0030] Working principle: When using this utility model, firstly, during assembly, the connecting seat 5 on one side of the second copper tube 6 can be screwed into the first copper tube 1, facilitating quick assembly and disassembly of the two sets of tubes and making it convenient to clean the inside of the two sets of tubes. Then, by changing the tilt angle of the blowing hole 7, compressed air can be directly blown to the root of the copper shavings. By setting 3-4 rows of blowing holes around the circumference, with 2-3 blowing holes in each row and each blowing hole having a diameter of 1.5-3.5mm, and each row being distributed at 90-120°, all copper shavings around the copper tube can be removed. By changing the hollow straight-through blowing rod to a hollow side-through blowing rod, the airflow direction is changed, and copper shavings are blown outward from the inner wall of the copper tube, eliminating the defect of copper shavings being blown into the inner cavity of the copper tube. Finally, when not in use, the connecting block 8 can be inserted into the internal threaded mounting head 2 to cover the internal threaded mounting head 2 and prevent larger particles from entering the interior and clogging the tube.
