Description

[Detailed Description of the Invention] Industrial Application Field The present invention relates to a support for an object to be plated, which is used to support an object to be plated in a plating solution, in which an annular step is formed on the bottom side of a recess.

Conventional structure and its problems Conventionally, as shown in FIGS. 3 and 4, a support 1 for an object to be plated is made of a conductive material such as a rod, and has a main body 2 whose wetted part is insulated, and a conductive material. and a support body 3, 3 protruding from a proper position of the main body into the support space.
..., and each support 3 is connected to two elastic rods 3.
3a and 3a, and an insulating coating 4 is applied to the elastic rod 3a except for the supporting portion 3a' near the tip. When supporting the object to be plated 5 made of faucet fittings or the like on the support 1 for the object to be plated, the operator should pinch the elastic rods 3a, 3a of each support body 3 near the base with his/her fingertips and remove the support part 3a. ′, 3a′ are kept close,
After inserting the recess 5a of the object 5 to be plated into the support portions 3a', 3a' near the tip of the support body 3, the fingertips are released to allow each support body 3 to support the object 5 to be plated. In this way, the plating object support 1 supporting the plating objects 5, 5... is immersed in the plating tank while suspended from the carrier chain of the plating device (not shown), and Plated object 5,
5... is applied with plating. However, the conventional support 1 for the object to be plated has the following drawbacks.

B. When supporting the object to be plated 5, the worker must pick up the base of the elastic rods 3a, 3a of each support body 3 with his or her fingertips, resulting in very poor work efficiency.

○B In order to prevent damage to the insulation coatings 4, 4 coated on the elastic rods 3a, 3a of each support body 3 due to contact between the insulation coatings 4, 4 and the object 5 to be plated, the terminal ends 4' of the insulation coatings 4, 4 are , 4' and the object to be plated 5, it is necessary to provide non-insulating areas 6, 6. but,
Providing the non-insulating areas 6, 6 requires plating removal work to remove the plating adhered to the non-insulating areas 6, 6, resulting in a decrease in the efficiency of use of the support.

○C The object to be plated 5 is supported by the support part 3 of the support body 3.
Since a' and 3a' are pressed against the inner circumferential wall surface of the recess 5a of the object to be plated 5, a point-line contact state is created. Therefore, when the object to be plated 5 is supported at an angle, the object to be plated is caused by slipping between the support parts 3a', 3a' and the inner peripheral surface of the recess 5a.
easily falls off, resulting in a decrease in plating work efficiency.

Purpose of the invention In order to solve the above-mentioned drawbacks, the purpose of the present invention is to provide a support for plated objects that is easy to attach to the support and can be stably supported without the need for conventional plating removal work. shall be.

Structure of the invention The gist of the invention is to support an object to be plated by forming an annular step on the bottom side of a recess, which is made of a conductive material such as a rod, and has a main body with an insulating coating on the wetted part, and a conductive body. A supporting device for an object to be plated, which is made of a material and includes a supporting body protruding from a proper place of the main body into the supporting space, the supporting body having an insulating coated branch and a tip of the branch having an outer diameter of the branch. It consists of a non-insulated seat portion formed to have a larger diameter, and a locking portion protruding from the upper surface of the seat portion to a diameter smaller than the outer diameter of the seat portion.

With this configuration, the object to be plated can be supported simply, quickly, and stably by simply inserting the tip of the support into the recess of the object and bringing the seat of the support into contact with the annular step of the object. In addition, since the insulating coated branch portion of the support body has a smaller diameter than the seat portion, it becomes possible to support the insulating coat and the object to be plated without any contact therewith.

DESCRIPTION OF EMBODIMENTS Hereinafter, the following explanation will be based on an embodiment shown in FIG. 1 showing the entirety of the support tool for an object to be plated (hereinafter referred to as the present tool) according to the present invention, and FIG. 2 showing an enlarged view of the main parts. explain. The present tool 7 is composed of a main body 8 and support bodies 9, 9, . . . that protrude from appropriate positions of the main body 8 into the support space. The main body 8 is formed by forming a framework of a conductive material such as a rod made of copper or the like, or is made of a single rod-shaped material (not shown), and the liquid contact part is covered with an insulating coating 8.
a, with a non-insulated hanger part 8 above.
b, 8b are formed. The support body 9 is made of a conductive material such as stainless steel, and as shown in FIG. A seat part 11 is formed at the tip to have a larger diameter (for example, 16 mmφ) than the outer diameter of the branch part 10 and has a non-insulated outer peripheral surface.
The locking portion 12 has a protruding diameter smaller than the outer diameter (for example, 8.8 mmφ) and has a non-insulated outer circumferential surface, and the upper peripheral edge of the seat portion 11 serves as a seat surface 11a. The outer peripheral shape of the seat portion 11 and the locking portion 12 is selected from an appropriate shape such as a circular shape or an angular shape. Further, the height dimension H of the seat portion 11 is equal to the height of the recessed portion 5 of the object to be plated 5.
The dimensions are such that the entire seat portion 11 can be immersed in the space a.

Function Next, the function of the present tool will be explained based on plating work using the present tool 7. Each support 9 of the main device 7
A small recess 5c is fitted into the tip of the recess 5a of the object 5 to be plated to form an annular stepped portion 5b of the object 5 to be plated.
Insert the locking part 12 of the support body 9 into the inside. Then,
The seat surface 11a of the support 9 comes into contact with the shoulder surface 5b' of the annular step 5b of the object 5 to be plated, and the support 9 stably supports the object 5 to be plated. The present device 7, which supports the object 5 to be plated on each support 9, has an upper hanger portion 8.
b, 8b are suspended from the carrier chain of a plating device (not shown), and are immersed in the plating tank as the carrier chain transports them, thereby plating the supported objects to be plated 5, 5... give Incidentally, since the seat 11 is recessed into the recess 5a of the object 5 to be plated, plating does not adhere to the outer peripheral surface of the seat 11 of the support body 9 of the present tool 7.

Effects of the invention The support for the object to be plated according to the invention has the following practical effects.

Just by fitting the recess of the object to be plated into the tip of each support, the support supports the object to be plated in a stable state, making it possible to quickly support the object to be plated with one hand, increasing the efficiency of supporting work. can be improved.

Since the insulating coating of the support does not come into contact with the object to be plated, the insulating coating will not be damaged.
Furthermore, since the seat of the support body is recessed into the recess of the object to be plated, plating does not adhere to the outer peripheral surface of the seat, and the conventional plating removal work can be omitted. As a result, the usage efficiency of the support is dramatically improved.

The locking part of the support body is inserted into the small recess of the object to be plated, and the bearing surface of the support body is brought into contact with the shoulder surface of the annular step of the object to be plated, so that the object to be plated is supported.
It can be supported in a stable state. the result,
The object to be plated does not fall off from the support, and the efficiency of plating work can be improved.

Since the object to be plated is supported by bringing the seating surface of the support into contact with the shoulder surface of the annular step of the object to be plated, the current-carrying area between the support and the object to be plated becomes large. As a result, the current flow efficiency is improved and uniform plating can be performed.
