Description

[Detailed description of the invention] The invention relates to a locking device that securely presses and hooks a hanger, which is used for suspending and surface treating objects such as aluminum extruded shapes, onto a conductive bar. It is.

Generally, in order to hang a long workpiece vertically on a conductive bar, as illustrated in FIGS. 2 and 3, a hook part 1 is provided above and a workpiece holding part 2 is provided below. However, conventionally, the workpiece 4 was hung by simply hooking the hanger A onto the conductive bar 3. There was a problem in that the object to be treated 4 fell off along with the hanger A during the immersion and pulling up.

Furthermore, since the hanger A is pressed against the conductive bar 3 only by its own weight and the weight of the object 4, it was not possible to obtain a contact pressure sufficient to cause a large current to flow.

Therefore, the purpose of the present invention is to provide a locking device in which the hanger for vertical hanging does not easily fall off the conductive bar, and the hanger and the conductive bar can come into contact with each other with sufficient pressure to allow a large current to flow. , which has a unique structure.

That is, in the hanger locking device according to the present invention, the lower ends of the pair of support arms vertically disposed below the carrier bar for conveying the processed material with a certain gap therebetween are tapered as the gap between the support arms approaches the lower end. A conductive bar for hanging a hanger having a hook portion and a workpiece holding portion is mounted and supported at this approaching portion, and between this conductive bar and the carrier bar, It is characterized in that a presser bar that can move along the support arm as the carrier bar is raised and lowered is inserted in parallel to the conductive bar.

Hereinafter, the present invention will be described according to the illustrated embodiment. The conductive bar 3 is attached to both sides of the carrier bar 5, and is attached to the lower ends of a pair of support arms 6, 6 hanging below the carrier bar 5. However, the support arms 6, 6 are brought closer to each other below the carrier bar 5 so that the gap I between the support arms 6, 6 tapers toward the lower end.

The presser bar 7 formed in a cylindrical shape is inserted into the above-mentioned gap A formed by the support arm of the link member, and is interposed between the carrier bar 5 and the conductive bar 3.

When the carrier bar 5 is erected, the conductive bar attachments of the support arms 6, 6 are located above the opening of the support part and are hooked onto the conductive bar 3, as shown in FIGS. 1 and 2. The hook portion 1 of the hanger A is pressed from directly above.

Therefore, the hanger A does not fall off the conductive bar 3 when the carrier par 5 is moved, and the hook part 1 is pressed against the conductive bar 3 more strongly than before, so that the contact pressure is sufficient to flow a larger current. can be obtained.

When the carrier par 5 is laid down in order to hook the hanger A holding the workpiece 4 onto the conductive bar 3 or to remove it, the hook part 1 is held down as shown in FIG. The presser bar 7, which had been held up, rolls along the slope of one of the support arms 6 and moves away from the hook part 1, so that the hanger A can be attached and detached.

4 and 5 show another embodiment of the present invention, in which a guide protrusion 8 is provided on the lower surface of the carrier par 5, and a presser bar is installed in the gap I between the support arms 6 and 6. 7 forms a guide vacant space for transfer.

Note that the guide protrusion 8 can be provided not only between the support arms 6, but also at an appropriate location on the lower surface of the carrier par 5.
