Description

[Detailed description of the invention] This invention is for attaching and fixing a low tank to a toilet bowl, for example, and relates to a plug that can be bolted from the front side in a place where it is impossible to work on the back side. The purpose is to provide a plug that makes work easier and more reliable.

Conventionally, when attaching and fixing a low tank to the tank mounting part of a toilet, a bolt fixing plug made of an elastic material was inserted into a hole formed in the tank mounting part, and the bolt was tightened to prevent it from being pulled out. Either by deforming and bulging and locking and fixing, or by inserting a nut-type fixing plug into the hole and inserting a bolt, the nut part of the plug is rotated 90' and fixed, In the former case, since the plug is made of rubber or the like, the nut may shift due to deterioration due to long-term use, or due to vibration or pressure during transportation or handling, and the nut may become unlatched to the mounting body and come out toward the bolt insertion side. was there.

The latter method has been devised to solve this problem, but
The bolt is tightened by rotating the nut part 90 degrees when the bolt comes into contact with the bolt, and although aging due to long-term use has been eliminated, in order to improve workability on the toilet and tank assembly line, bolt tightening machines are used to improve workability. For example, it is preferable to use an air driver), but since this tightening machine uses mechanical pressure and rotation, the pivot in the vertical slot of the hanging piece that supports the nut comes off, and the nut falls due to the pressing force of the tightening machine. Therefore, it had to be done manually, which was extremely time-consuming and required not only skill but also high costs.

The present invention has been devised in view of the above points, and an example of its implementation will be described below with reference to the drawings. A substantially rectangular nut portion 3 formed of metal or the like having a screw hole 2 screwed in the shape of a shape, and a head portion 8 having a slope 9 inclined toward the screw hole 2, and a pivot shaft of the nut portion 3. 1, and a plug main body 7 that locks onto the upper surface of the mounting port 15 of the mounting body 12 and is cut out from the locking head 6 and has a bolt hole 6' in the center. In the plug, a vertical hole 4 is formed in the hanging pieces 5 in the same direction as the hanging direction of the hanging pieces 5. A protruding piece 10 is formed in the same direction as the long side direction of 3.

When using this invention, for example, the toilet bowl 1 which is the mounting body
When attaching and fixing the low tank 12 to the toilet bowl 11, the rain hanging pieces 5 and 5 are attached by passing the shaft 1 through the vertical hole 4 of the hanging piece 5 of the plug main body 7 into the hole 14 of the low tank mounting part 13 of the toilet bowl 11. Insert the plug from the hanging piece 5 side with a nut attached therebetween, lock the locking head 6 on the upper surface of the outer periphery of the hole 14, and connect the hole 15 of the low tank 12 and the bolt hole 6' of the locking head 6. The bolt 16 is inserted from inside the low tank 12 through the hole 15 and the hole 6' in this order through the washer 17 and the backing 18, and the tip 16' of the bolt 16 is inserted into the head 8 having the slope 9 of the nut part 3. By further inserting the bolt 16, the tip 16' of the bolt 16
The nut part 3 descends along the slope 9 of the nut part 3, thereby rotating around the pivot 1, and the tip 16' reaches the open end of the screw hole 2.

Thereafter, by threading the bolt 16, the nut portion 3 is drawn into the threaded hole 2.

That is, the nut part 3 is raised by the pivot 1 being guided in the vertically elongated hole 4, and the low tank 12 is fixed to the toilet bowl 11.

However, even if the nut part 3 attempts to detach from the hanging piece 5 using a bolt tightening machine such as an air driver, the protruding piece part 10 formed at the tip of the pivot 1 of the nut part 3 will not move away from the hanging piece 5.
Since the nut part 3 passes through the vertically elongated hole 4 and is locked to the hanging piece 5, the nut part 3 will not come off, making it possible to use a bolt tightening machine.

Here, when fitting the nut part 3 to the plug main body 7, since the hanging piece 5 is a long body, its lower end is opened and the projecting direction of the protruding piece part 10 is suspended along the long side of the vertically elongated hole 4. Just insert it in the same direction as the hanging direction of the piece 5.

In addition, 19 in the figure is a cut groove, and the locking protrusion 20 located in the cut groove 19 is provided to protrude in the same direction on the same surface as the pivot 1, and the hanging direction of the hanging piece 5 and the nut The long side direction of the part 3 is aligned with the long side direction to facilitate insertion into the hole 14 of the mounting body 11, and when the nut part 3 rotates about the pivot 1, it is locked to the side surface 5'' of the hanging piece 5. The projection 20 abuts the bolt 16 so that the nut portion 3 is perpendicular to the insertion direction of the bolt 16, thereby facilitating insertion into the screw hole 2.

The present invention, which has the configuration described above, makes it possible to use a plug with a nut hook, which has traditionally been a strong mounting method, with a mechanical tool such as an air driver,
This prevents the lower end of the hanging piece from spreading due to the long length of the hanging piece, and prevents the nut from separating from the hanging piece even during mechanical tightening with strong pressing force, which greatly improves workability. This allows for hassle-free and reliable installation.

Therefore, it achieves its intended purpose.
