DETAILED DESCRIPTION OF THE INVENTION

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to various panels used for assembling and constructing prefabricated refrigerators, freezers, etc., for example, panels such as wall panels, floor panels, ceiling panels, panels with doors, panels with windows and the like. The present invention relates to a panel connecting and tightening device used for connecting and firmly connecting panels to each other to strengthen a connected state.

[0002]

2. Description of the Related Art Conventional panel connecting means is such that connecting brackets, such as small rectangular plates, are connected by screws at set positions on opposite sides of the panel to be connected. In addition to the time and trouble required for installation, there is a drawback that connection and tightening cannot be made firmly, causing individual variations.

In addition, since the metal fittings are exposed and protruded from the outer surface of the side of the panel, the appearance is poor. The metal fittings are caught or come into contact with the built-in articles, causing scratches. Because there were issues such as becoming

[0004] In order to solve the above-mentioned conventional problems, the panel connection is tightened more firmly and uniformly, and is not exposed or protruded to the outside of the panel so as not to obstruct or impair the appearance. An attachment device has been desired.

[0005]

SUMMARY OF THE INVENTION Accordingly, the present invention is based on the idea of connecting and tightening a panel with a so-called bolt joint by screwing and tightening a bolt and a nut embedded in advance on each side of the panel to be connected. In particular, the bolt configuration is unique to the present invention in which the head is formed as a bevel gear, and a unique handle is separately provided in the present invention in which a bevel gear is formed at the tip of a rod for rotating the bolt. SUMMARY OF THE INVENTION It is an object of the present invention to provide a panel connecting and fastening device which solves the above-mentioned conventional problems.

[0006]

That is, according to the present invention, there is provided a bolt provided with a nut on the side of one panel to be connected, and a head formed on a bevel gear at a position opposite to the nut on the side of the other panel. And a handle with a bevel gear formed at the end of the rod,

[0007] The bevel gear of the handle and the bevel gear of the bolt are meshed with the sides of the panel abutting against each other and the nut and the bolt are opposed to each other, and the handle and the bevel gear are rotated to rotate the bolt and the nut. The problem has been solved by a panel connecting and tightening device provided so as to screw together and connect and tighten both panels.

[0008]

Next, embodiments of the present invention will be described. (See FIGS. 1 to 5) The nut 2 is embedded in the side wall of one panel 1a (or 1b) to be connected, and the other panel 1b is connected.
A bolt 3 is embedded in a position facing the nut 2 within the thickness of the side wall of (or 1a) so as to be rotatable and forward / backward in a set dimension.

The bolt 3 has a bevel gear 4 formed at its head and a circumferential groove 6 formed at the tip of a short shaft 5 projecting from the center of the bevel gear 4.

A bevel gear 8 is formed at the tip of the rod 7, and a handle 10 is separately provided at the center of the bevel gear 8, and a protruding fork 9 for engaging with the circumferential groove 6 of the bolt 3. Thing,

The side edges of the panels 1a and 1b are brought into contact with each other, the fork 9 of the handle 10 is engaged with the circumferential groove 6 of the bolt 8, and the bevel gears 4 and 8 are engaged with each other. By rotating 10 and rotating both bevel gears 4 and 8, the bolt 3 and the nut 2 are screwed together, and both panels 1a, 1b
And a panel tightening device for connecting and tightening.

Reference numeral 13 denotes a frame member on the side of the panels 1a and 1b, reference numeral 14 denotes a guide sleeve of the bolt 3, and reference numeral 15 denotes a packing material interposed in a connecting portion of the panels 1a and 1b.

[0013]

After contacting the sides of the panels 1a and 1b,
Hole 11 made in outer plate 12 of panel 1b (or 1a)
To engage with the circumferential groove 6 of the bolt 3 and engage the bevel gears 4, 8 of the two 3, 10 with the guide of the engagement.

When the handle 10 is rotated in the above state, the meshed bevel gears 4 and 8 rotate, and the bolts 3 rotate and screw into the opposed nuts 2 so that the panels 1a and 1b are connected, and The nut 2, that is, the panel 1 a is pulled in the direction of the panel 1 b by the rotational screwing, and the panels are strongly fastened to each other.

Further, the connection between the panels 1a and 1b is released,
When removing both panels, the handle 10 is rotated in the reverse direction, the bolt 3 is rotated in the reverse direction, and the screw engagement with the nut 2 is removed.

[0016]

[Effect] The panel can be quickly tightened and disconnected by simply turning the bolt using the handle from the outside of the panel, so the workability of connecting and removing the panel can be greatly simplified and improved. Has the effect.

Only the small hole for inserting the handle can be seen on the outside of the panel, and it is sufficient to cover the small hole. There is no risk of damage.

Since the panel is fastened by bolt joints using bolts and nuts, there is no variation and it is very accurate and strong.
