Multi-layer conductive hanger for batch electroplating of valve stem spool

Abstract

This utility model relates to the field of electroplating conductive hangers, and discloses a multi-layer conductive hanger for batch electroplating of valve stems and valve cores. The novel design includes a main conductive rod with a main conductive hook at its top, a conductive extension rod at its bottom, a secondary conductive rod at its bottom, and a conductive base at its bottom. Conductive support rods are evenly arranged on the outer walls of the main and secondary conductive rods. This utility model achieves this by threading the main conductive rod, conductive extension rod, secondary conductive rod, and conductive base together. This allows for rapid adjustment of the distance between the main and secondary conductive rods according to the length of the valve stem and valve core, and the number of secondary conductive rods can be flexibly increased or decreased based on the batch electroplating quantity of the valve stem and valve core. This significantly improves the adaptability of the device, eliminating the need for a single-specification custom-made hanger when batch electroplating valve stems and valve cores.

Description

Technical Field

[0001] This utility model belongs to the field of electroplating conductive hanger technology, specifically a multi-layer conductive hanger for batch electroplating of valve stems and valve cores. Background Technology

[0002] In the electroplating of precision parts such as valve stems and valve cores, conductive racks are the core auxiliary equipment to ensure electroplating quality and efficiency. Traditional multi-layer conductive racks are mostly made by welding multiple single-layer fixtures, which makes it impossible to make convenient structural adjustments according to valve stems and valve cores of different lengths, thus reducing their adaptability. To address this, we propose a multi-layer conductive rack for batch electroplating of valve stems and valve cores. Utility Model Content

[0003] The purpose of this invention is to provide a multi-layer conductive hanger for batch electroplating of valve stems and valve cores, so as to solve the problems mentioned in the background art.

[0004] To achieve the above objectives, this utility model provides the following technical solution: a multi-layer conductive hanger for batch electroplating of valve stems and valve cores, comprising a main conductive rod, a main conductive hook at the top of the main conductive rod, a conductive extension rod at the bottom of the main conductive rod, a secondary conductive rod at the bottom of the conductive extension rod, a conductive base at the bottom of the secondary conductive rod, conductive support rods evenly arranged on the outer walls of the main conductive rod and the secondary conductive rod, a secondary conductive hook on the outer side of the conductive support rod, and an insulating rubber sleeve covering the outer sides of the main conductive rod, the conductive extension rod, the secondary conductive rod, the conductive base, and the conductive support rod. A set of screws is connected between the main conductive rod and the conductive extension rod, between the conductive extension rod and the secondary conductive rod, and between the secondary conductive rod and the conductive base. An insulating sealing ring is sleeved on the outer side of the screws, and the insulating sealing ring is in contact with the insulating rubber sleeve.

[0005] Preferably, the three sets of screws are respectively disposed on the top of the conductive extension rod, the secondary conductive rod, and the conductive base. The screw located on the top of the conductive extension rod is integrally formed with the conductive extension rod, the screw located on the top of the secondary conductive rod is integrally formed with the secondary conductive rod, and the screw located on the top of the conductive base is integrally formed with the conductive base.

[0006] Preferably, the upper and lower sides of the insulating sealing ring located between the main conductive rod and the conductive extension rod are respectively attached to the opposite sides of the main conductive rod and the conductive extension rod, and are respectively attached to the opposite sides of the two sets of insulating rubber sleeves covering the outside of the main conductive rod and the conductive extension rod.

[0007] Preferably, the upper and lower sides of the insulating sealing ring located between the conductive extension rod and the auxiliary conductive rod are respectively attached to the opposite sides of the conductive extension rod and the auxiliary conductive rod, and are respectively attached to the opposite sides of the two sets of insulating rubber sleeves covering the outside of the conductive extension rod and the auxiliary conductive rod.

[0008] Preferably, the upper and lower sides of the insulating sealing ring located between the secondary conductive rod and the conductive base are respectively attached to the opposite sides of the secondary conductive rod and the conductive base, and are respectively attached to the opposite sides of the two sets of insulating rubber sleeves covering the outer side of the secondary conductive rod and the conductive base.

[0009] Preferably, the screw has a mounting hole on its left side, a spring is installed in the mounting hole, a round-headed pin is installed on the left side of the spring, and a neodymium iron boron magnet is embedded on the left side of the round-headed pin. The bottom of the main conductive rod, the conductive extension rod, and the auxiliary conductive rod all have threaded holes. The left side of the inner wall of the threaded hole has a positioning hole. The screw is screwed into the threaded hole, the round head of the round-headed pin is inserted into the positioning hole, and the neodymium iron boron magnet is magnetically attracted to the positioning hole.

[0010] Compared with the prior art, the beneficial effects of this utility model are: by threading the main conductive rod, the conductive extension rod, the auxiliary conductive rod and the conductive base together, the distance between the main conductive rod and the auxiliary conductive rod can be quickly adjusted according to the length of the valve stem and valve core. Furthermore, the number of auxiliary conductive rods can be flexibly increased or decreased according to the batch electroplating quantity of the valve stem and valve core, thereby greatly improving the adaptability of the device and eliminating the need to use a single-specification customized special hanger when performing batch electroplating of the valve stem and valve core.

[0011] The insulating sealing rings between the main conductive rod and the conductive extension rod, between the conductive extension rod and the auxiliary conductive rod, and between the auxiliary conductive rod and the conductive base not only fill the connection gaps between the components and prevent the electroplating solution from seeping in and corroding the threads, but also seamlessly connect the outer insulating sleeves, avoiding the risk of short circuits caused by exposed conductive components. By covering the non-contact area of ​​the rack with the insulating sleeves, the service life of the rack in acid and alkaline electroplating environments is further improved.

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0019] Please see Figure 1-3 A multi-layer conductive hanger for batch electroplating of valve stems and valve cores includes a main conductive rod 1, a main conductive hook 16 fixedly mounted on the top of the main conductive rod 1, a conductive extension rod 11 placed at the bottom of the main conductive rod 1, a secondary conductive rod 12 placed at the bottom of the conductive extension rod 11, a conductive base 13 placed at the bottom of the secondary conductive rod 12, and conductive support rods 14 uniformly fixedly mounted on the outer walls of the main conductive rod 1 and the secondary conductive rod 12. Secondary conductive hooks 15 are fixedly mounted on the outer side of the conductive support rods 14. The auxiliary conductive hook 15 suspends the valve stem and valve core. The main conductive rod 1, the conductive extension rod 11, the auxiliary conductive rod 12, the conductive base 13 and the conductive support rod 14 are all covered with insulating rubber sleeves 17. A set of screws 21 are connected between the main conductive rod 1 and the conductive extension rod 11, between the conductive extension rod 11 and the auxiliary conductive rod 12 and between the auxiliary conductive rod 12 and the conductive base 13. An insulating sealing ring 2 is sleeved on the outside of the screw 21, and the insulating sealing ring 2 is in contact with the insulating rubber sleeve 17.

[0020] Three sets of screws 21 are respectively fixedly installed on the top of the conductive extension rod 11, the auxiliary conductive rod 12, and the conductive base 13. The screw 21 located on the top of the conductive extension rod 11 is integrally formed with the conductive extension rod 11, the screw 21 located on the top of the auxiliary conductive rod 12 is integrally formed with the auxiliary conductive rod 12, and the screw 21 located on the top of the conductive base 13 is integrally formed with the conductive base 13. The upper and lower sides of the insulating sealing ring 2 located between the main conductive rod 1 and the conductive extension rod 11 are respectively attached to the opposite sides of the main conductive rod 1 and the conductive extension rod 11. The insulating sealing ring 2 located between the conductive extension rod 11 and the auxiliary conductive rod 12 has its upper and lower sides respectively attached to the opposite sides of the conductive extension rod 11 and the auxiliary conductive rod 12, and also to the opposite sides of the two sets of insulating sleeves 17 covering the outer sides of the conductive extension rod 11 and the auxiliary conductive rod 12. The insulating sealing ring 2 located between the auxiliary conductive rod 12 and the conductive base 13 has its upper and lower sides respectively attached to the opposite sides of the auxiliary conductive rod 12 and the conductive base 13. The two sets of insulating sleeves 17, which are respectively attached to the opposite sides of the auxiliary conductive rod 12 and the conductive base 13, are in contact with each other. Through the insulating sealing rings 2 between the main conductive rod 1 and the conductive extension rod 11, between the conductive extension rod 11 and the auxiliary conductive rod 12, and between the auxiliary conductive rod 12 and the conductive base 13, the gaps between the components are filled, preventing electroplating solution from seeping in and corroding the threads. This also ensures a seamless connection of the outer insulating sleeves 17, avoiding the risk of short circuits caused by exposed conductive components. By covering the non-conductive components of the hanger with the insulating sleeves 17... The contact area further enhances the service life of the hanger in acid and alkali electroplating environments. A mounting hole is provided on the left side of the screw 21, and a spring 22 is fixedly installed in the mounting hole. A round-headed pin 23 is fixedly installed on the left side of the spring 22, and a neodymium iron boron magnet 24 is embedded on the left side of the round-headed pin 23. Threaded holes are provided at the bottom of the main conductive rod 1, the conductive extension rod 11, and the auxiliary conductive rod 12. A positioning hole is provided on the left side of the inner wall of the threaded hole. The screw 21 is screwed into the threaded hole, and the round head of the round-headed pin 23 is inserted into the positioning hole, and the neodymium iron boron magnet 24 is magnetically attracted in the positioning hole.

[0021] Working principle: The screws 21 on the top of the conductive extension rod 11, the auxiliary conductive rod 12, and the conductive base 13 are screwed into the threaded holes at the bottom of the main conductive rod 1, the conductive extension rod 11, and the auxiliary conductive rod 12, respectively, to form a multi-layer hanger. The valve stem and valve core can then be suspended on multiple sets of auxiliary conductive hooks 15 on the outside of the main conductive rod 1 and the auxiliary conductive rod 12. When the screw 21 is tightened in the threaded hole, the spring 22 will drive the round head pin 23 to insert into the positioning hole in the threaded hole, and the neodymium iron boron magnet 24 will be magnetically attracted in the positioning hole, thereby improving the anti-loosening property of the screw 21 in the threaded hole. This improves the stability of the entire multi-layer hanger. Furthermore, the insulating sealing rings 2 between the main conductive rod 1 and the conductive extension rod 11, between the conductive extension rod 11 and the auxiliary conductive rod 12, and between the auxiliary conductive rod 12 and the conductive base 13 not only fill the gaps between the components and prevent the electroplating solution from seeping in and corroding the threads, but also seamlessly connect the outer insulating sleeve 17, avoiding the risk of short circuits caused by exposed conductive components. By covering the non-contact area of ​​the hanger with the insulating sleeve 17, the service life of the hanger in acid and alkaline electroplating environments is further improved.

[0022] After the screw 21 at the top of the auxiliary conductive rod 12 is screwed away from the threaded hole at the bottom of the conductive extension rod 11, the threaded hole at the bottom of the conductive extension rod 11 can be screwed into the screw 21 at the top of another set of conductive extension rods 11. Then, the screw 21 at the bottom of the auxiliary conductive rod 12 can be screwed into the threaded hole at the bottom of another set of conductive extension rods 11. This adjusts the distance between the main conductive rod 1 and the auxiliary conductive rod 12, allowing the auxiliary conductive hooks 15 on the outside of the main conductive rod 1 and the auxiliary conductive rod 12 to suspend valve stems and valve cores of different lengths. Similarly, after the conductive base 13 is screwed away from the auxiliary conductive rod 12, the auxiliary conductive rod 12 can be threaded into another set of auxiliary conductive rods 12. This changes the number of layers in the multi-layer hanger, further improving the adaptability for batch electroplating of valve stems and valve cores.

[0023] It is worth noting that the round-headed pin 23 and the spring 22 only have partial contact with the conductive parts in the device. As a result, the current will preferentially pass through the threaded connection with the larger area. Therefore, the current shunting generated by the round-headed pin 23 and the spring 22 can be ignored. Furthermore, the neodymium iron boron magnet 24 itself has poor conductivity and its resistance is much higher than that of copper and iron. Moreover, the neodymium iron boron magnet 24 is only embedded in the round-headed part of the round-headed pin 23, and the magnetic contact area with the threaded hole is small. It does not interfere with the main conductive path, that is, it does not replace the conductive function of the threaded connection.
