Although the structure of the wire does not matter, a spiral wire is suitable. 3 is a screw hole for a mounting screw drilled at the lower end of the bolt. Reference numeral 4 denotes a receiving metal fitting that is inserted into the guide wire and movably moves up and down. The receiving metal fitting consists of an outer metal fitting 5, a supporting metal fitting 6, a spring 7, and a ball 8 which is an engaging body that is fitted into the supporting metal fitting. The outer metal fitting 5 is a cylindrical metal fitting having a conical hole 9 extending through it in the axial direction, and a through hole 11 communicating with the conical hole 9 is bored in the cylindrical metal fitting by a cap-like bottomed plate fixed by caulking. Reference numeral 12 denotes a fitting recess for a fixing bolt mounting nut N provided on the upper surface of the outer metal fitting. The support fitting 6 is inserted into the conical hole 9 of the outer fitting and consists of a conical head 13 and a support part 14, and the lower part of the support part has a knob part 14' protruding from the bottom plate of the outer fitting. Reference numeral 15 denotes a guide wire insertion hole extending through the support fitting in the vertical axis direction. Reference numeral 16 denotes a plurality of fitting holes drilled in the conical head of the support metal fitting, which communicate with the insertion hole 15, and the locking balls 8 are loosely fitted into the holes so as to come into contact with the guide wire so that they can be locked. The support metal fitting 6 is movably inserted into the conical hole of the outer metal fitting, and is constantly pushed up and supported into the conical hole by the upward action of a spring 7 compressed between the conical head of the support metal fitting and the bottom plate of the receiving metal fitting. There is.

The bracket 4 includes a support bracket, a spring, and a spring inside the outer bracket.
The ball is integrally assembled and movably inserted into the guide wire 1 which is inserted through the conical hole and the insertion hole of the support fitting communicating with the conical hole. The inserted receiving fitting 4 is caused to bite into the guide wire inserted through the receiving fitting due to its own gravity or the loading force of the device inserted onto the receiving fitting, with the plurality of balls loosely fitted into the insertion holes of the supporting fitting. The receiving metal fitting and the unloaded goods can be fixed to the guide wire at any time.

When moving the bracket up and down, if you release the load on the bracket itself or the bracket, the ball will stop engaging with the wire, allowing the bracket to move freely. , knob part 14'
Pinch and move up and down.

Note that the attachment body installed inside the outer metal fitting may be a piece other than a ball.

When installing indoor equipment K such as electrical appliances on the ceiling surface W, use multiple mounting bolts V installed below the ceiling surface.
Attach an appropriate number of guide wires to the
Insert the end edge into the mounting hole H of the equipment K, and then insert it into the fixing nut N of the mounting bolt fitted into the fitting recess on the upper surface of the holder, and the through hole communicating with the holder 4, and insert it into the ceiling. Using a stepladder C or the like on the surface, the cargo is sequentially unloaded onto the ceiling surface via the guide wire. In this case, as mentioned above, the receiving bracket strongly engages and engages the guide wire to support the unloaded item due to its own gravity or the load of the unloaded item, so even if you remove your hand when installing equipment etc., the load will remain intact. It won't fall off.

After installing the device K on the ceiling, remove the guide wire mounting screw 2 and collect the wire and holder.

(Effects of the present invention) Due to the structure, operation, and method of use described above, when installing indoor equipment on the ceiling, the equipment can be unloaded straight onto the ceiling fixing bolt via a mounting screw with a smaller diameter than the fixing bolt and a guide wire. At the same time, if the lifted fixing nut is tightened to the mounting bolt via the guide wire, the mounting and installation will be completed smoothly.

The guide wire and bracket can be used as mounting equipment.
It is a practical product that can be used many times, has a simple structure, and can be provided at a low price.

In terms of functionality, installation work that previously required erecting scaffolding for installation or installation work by multiple people depending on the installation location can now be installed by a single person. The fixed nut set in the guide wire can be screwed straight on without removing the guide wire, which not only saves labor, but also allows for smooth positioning and alignment of the mounting bolt and the unloaded product mounting hole, making work easier. It has the effect of greatly contributing to efficiency and efficiency.

In addition, even if there is indoor equipment directly below the installation part, it is possible to unload and move the load from a distance using the bending of the guide wire, eliminating unnecessary stains on the indoor equipment and reducing installation costs. This is an orthosis that exhibits extremely useful functions to save labor and improve efficiency.
