Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of coating testing equipment, and in particular to a corrosion-resistant copper wire coating testing mechanism. Background Technology
[0002] Copper wire, as an important conductive material, is widely used in many fields such as power transmission, communication, and electronic equipment. However, copper is prone to reacting with oxygen, water vapor, and some corrosive media in the natural environment, leading to the formation of copper rust on the surface of the copper wire. This affects the conductivity, mechanical properties, and service life of the copper wire. Plating a coating on the surface of the copper wire can increase its corrosion resistance.
[0003] According to the announcement number CN119985277A, an alloy wire corrosion resistance testing device provides an independent testing platform for the alloy wire in the coiled state. When the alloy wire is stretched to a certain length, the part of the alloy wire to be tested is sealed and clamped. After the part of the alloy wire to be tested is completely immersed in the test solution, the pressure on the alloy wire and the hydraulic pressure of the solution are changed within a rated time, thereby effectively simulating the real-time corrosion changes of the alloy wire during its use.
[0004] Existing testing institutions for corrosion-resistant copper wire coatings use specific sealing clamps to fix both ends of the copper wire and then place it in a corrosive solution environment for testing. However, this testing method requires a high degree of sealing effect from the sealing ring. If the sealing ring has minor defects or aging, it may lead to leakage of the corrosive solution, requiring regular inspection and replacement of the sealing ring, which increases testing costs and maintenance workload.
[0005] Therefore, there is an urgent need to provide a testing mechanism for corrosion-resistant copper wire coatings to solve the above problems. Utility Model Content
[0006] The technical problem to be solved by this utility model is to overcome the shortcomings of the prior art and provide a test mechanism for corrosion-resistant copper wire plating.
[0007] To solve the above-mentioned technical problems, the present invention provides a technical solution: a corrosion-resistant copper wire plating testing mechanism, including a bottom shell, a waste liquid drawer slidably installed inside the bottom shell, and a transparent window on one side of the bottom shell;
[0008] A test shell is fixedly installed at the top of the bottom shell, an installation shell is fixedly installed on one side of the test shell, and an electric valve is fixedly installed at the bottom of the test shell.
[0009] The test shell has a sealing shell attached to its top. The outer side of the sealing shell is provided with a clamping mechanism to seal both ends of the anti-corrosion copper wires of different sizes. The inner side of the mounting shell is provided with a shaping mechanism to make the middle position of the anti-corrosion copper wire into a U-shape.
[0010] The above technical solution involves adding a corrosive solution inside the test shell to test the corrosion resistance of the anti-corrosion copper wire plating. A sealing shell is used to seal the test shell, and the corrosive solution is discharged into a waste liquid drawer through an electric valve. The capacity of the waste liquid drawer can be observed through a transparent window in the bottom shell.
[0011] The present invention is further configured such that: the clamping mechanism includes fixed insert rods respectively fixed to both sides of the rear end of the sealing shell, and two slot plates are fixedly installed on both sides of the rear end of the test shell, and the outside of the fixed insert rods is fitted into the inside of the slot plates.
[0012] Through the above technical solution, the sealing shell is connected to the slot plate of the test shell by a fixed insertion rod.
[0013] The present invention is further configured such that: a threaded rotating rod is rotatably installed at the middle of the rear end of the sealing shell, and a threaded block is fixedly installed at the middle of the rear end of the test shell, and the outside of the threaded rotating rod is threadedly connected to the inside of the threaded block.
[0014] Using the above technical solution, the threaded rod is rotated by hand, and the threaded rod moves up and down through the threaded block, so that the sealing shell aligns with the test shell.
[0015] The present invention is further configured such that: a first sealing ring is fitted and installed on both sides of the bottom end of the sealing shell, and a second sealing ring is fitted and installed on both sides of the top end of the test shell, and the first sealing ring and the second sealing ring are sealed and connected to the corrosion-resistant copper wire.
[0016] The above technical solution involves setting first and second sealing rings of different specifications to seal both ends of corrosion-resistant copper wires of different sizes. The sealing shell and the test shell combine to seal the first and second sealing rings.
[0017] The present invention is further configured such that: the shaping mechanism includes a lifting guide rail fixed to the middle of the front end of the test shell, a rack plate is slidably installed on the outside of the lifting guide rail, and a U-shaped plate is fixedly installed on the top of the rack plate.
[0018] Using the above technical solution, the rack and pinion plate and the U-shaped plate are raised and lowered by hand via the lifting guide rail.
[0019] The present invention is further configured such that: mounting gears are rotatably mounted on both sides of the front end of the test shell, the outer sides of the two mounting gears respectively mesh with the two sides of the rack plate, fixing plates are fixedly mounted on both sides of the inner wall of the mounting shell, and a telescopic rack with one end penetrating through and extending to the outside of the mounting shell is slidably mounted on the outer side of the two fixing plates, and the outer sides of the two telescopic racks respectively mesh with the outer surfaces of the two mounting gears.
[0020] Through the above technical solution, the rack plate drives two mounting gears to rotate, and the two mounting gears respectively drive two telescopic racks to retract into the mounting housing. The telescopic racks are stably extended and retracted through the fixed plate.
[0021] The present invention is further configured such that: the rack plate and the two telescopic racks are not on the same plane, one end of each of the two telescopic racks is fixedly installed with a winding column, and two shaping plates are fixedly installed on one side of the mounting shell.
[0022] Using the above technical solution, the two ends of the anti-corrosion copper wire are wound around two winding posts by hand, and the anti-corrosion copper wire is shaped by the cooperation of a U-shaped plate and two shaping plates.
[0023] The beneficial effects of this utility model are as follows:
[0024] 1. This utility model has a shaping mechanism. By lifting and moving the U-shaped plate, the two telescopic racks retract accordingly, thereby shaping the anti-corrosion copper wire fixed between the two winding columns, so that the middle position of the straight line is U-shaped, which better meets the test requirements and does not require too high sealing performance, thus reducing the testing cost and maintenance workload of the equipment.
[0025] 2. This utility model, by providing a clamping mechanism and setting first and second sealing rings of different specifications, seals both ends of corrosion-resistant copper wires of different sizes. The test shell and the sealing shell form a sealed environment, ensuring the sealing effect. It is convenient to test the corrosion resistance of the copper wire plating through the test shell, and is easy to operate and maintain. Attached Figure Description

[0031] The preferred embodiments of the present invention will now be described in detail with reference to the accompanying drawings, so that the advantages and features of the present invention can be more easily understood by those skilled in the art, thereby making a clearer and more definite definition of the scope of protection of the present invention.
[0032] Please see Figures 1-4 A testing mechanism for corrosion-resistant copper wire plating includes a base shell 1, a waste liquid drawer 2 slidably installed inside the base shell 1, a transparent window on one side of the base shell 1, a test shell 3 fixedly installed at the top of the base shell 1, an installation shell 4 fixedly installed on one side of the test shell 3, an electric valve 7 fixedly installed at the bottom of the test shell 3, a sealing shell 5 attached to the top of the test shell 3, and a clamping mechanism 6 for sealing both ends of corrosion-resistant copper wires of different sizes on the outside of the sealing shell 5. The clamping mechanism 6 includes fixed insert rods 601 fixed to both sides of the rear end of the sealing shell 5, two slot plates 602 fixedly installed on both sides of the rear end of the test shell 3, the outside of the fixed insert rods 601 fitting into the inside of the slot plates 602, a threaded rotating rod 603 rotatably installed at the middle of the rear end of the sealing shell 5, a threaded block 604 fixedly installed at the middle of the rear end of the test shell 3, the outside of the threaded rotating rod 603 threadedly connected to the inside of the threaded block 604, and two threaded blocks 604 fixedly installed at the bottom of the sealing shell 5. The test shell 3 is fitted with a first sealing ring 605 on each side, and a second sealing ring 606 is fitted on both sides of the top of the test shell 3. The first sealing ring 605 and the second sealing ring 606 are sealed to the anti-corrosion copper wire. A corrosive solution is added to the inside of the test shell 3 to test the anti-corrosion performance of the anti-corrosion copper wire coating. The sealing shell 5 seals the test shell 3. The corrosive solution is discharged into the waste liquid drawer 2 through the electric valve 7. The capacity of the waste liquid drawer 2 can be observed through the transparent window of the bottom shell 1. By setting different specifications of the first sealing ring 605 and the second sealing ring 606, the two ends of the anti-corrosion copper wire of different sizes can be sealed. The threaded rod 603 is rotated by hand. The threaded rod 603 is raised and lowered by the threaded block 604, so that the sealing shell 5 is connected to the slot plate 602 of the test shell 3 through the fixed insertion rod 601. The sealing shell 5 and the test shell 3 form a combined seal for the first sealing ring 605 and the second sealing ring 606.
[0033] like Figure 3 and Figure 4As shown, the mounting shell 4 has an internal shaping mechanism 8 that transforms the middle of the anti-corrosion copper wire into a U-shape. The shaping mechanism 8 includes a lifting guide rail 801 fixed to the middle of the front end of the test shell 3. A rack plate 802 is slidably mounted on the outside of the lifting guide rail 801. A U-shaped plate 803 is fixedly mounted on the top of the rack plate 802. Mounting gears 804 are rotatably mounted on both sides of the front end of the test shell 3. The outer sides of the two mounting gears 804 mesh with the two sides of the rack plate 802 respectively. Fixing plates 805 are fixedly mounted on both sides of the inner wall of the mounting shell 4. A telescopic rack 806 with one end penetrating through and extending to the outside of the mounting shell 4 is slidably mounted on the outside of each of the two fixing plates 805. The outer sides of the two telescopic racks 806 respectively mesh with the two mounting gears. The outer surfaces of 804 mesh with each other. The rack plate 802 and the two telescopic racks 806 are not on the same plane. One end of each of the two telescopic racks 806 is fixedly installed with a winding post 807. Two shaping plates 808 are fixedly installed on one side of the mounting shell 4. The two ends of the anti-corrosion copper wire are wound onto the two winding posts 807 by hand. The rack plate 802 and the U-shaped plate 803 are driven to rise and fall through the lifting guide rail 801 by hand. The rack plate 802 drives the two mounting gears 804 to rotate accordingly. The two mounting gears 804 drive the two telescopic racks 806 to retract into the mounting shell 4. The telescopic racks 806 are stably extended and retracted through the fixing plate 805, so that the U-shaped plate 803 and the two shaping plates 808 cooperate to shape the anti-corrosion copper wire.
[0034] In use, the anti-corrosion copper wire is wound around two winding posts 807 by hand. The rack plate 802 and U-shaped plate 803 are then manually driven to rise and fall via the lifting guide rail 801. The rack plate 802 drives two mounting gears 804 to rotate, which in turn drives two telescopic racks 806 to retract into the mounting shell 4. The telescopic racks 806 are stably extended and retracted via the fixing plate 805, allowing the U-shaped plate 803 and the two shaping plates 808 to work together to shape the anti-corrosion copper wire. The shaped anti-corrosion copper wire is then placed into the second sealing ring 606 at the top of the test shell 3. A corrosive solution is added inside the test shell 3 to test the corrosion resistance of the anti-corrosion copper wire plating. This effectively simulates the real-time corrosion changes of the anti-corrosion copper wire plating during its use. The threaded rod 603 is rotated by hand, and the threaded rod 603 moves up and down through the threaded block 604, so that the sealing shell 5 is connected to the slot plate 602 of the test shell 3 through the fixed insertion rod 601. The sealing shell 5 and the test shell 3 form a combined seal for the first sealing ring 605 and the second sealing ring 606. The corrosive solution is discharged into the waste liquid drawer 2 through the electric valve 7, and the capacity of the waste liquid drawer 2 can be observed through the transparent window of the bottom shell 1.
