Description

[Detailed explanation of the invention] The purpose of this invention is to simplify the structure, make it easier to handle, and improve productivity as a connection mechanism between insulation panels used in prefabricated refrigerators, etc. A steeply sloped surface is provided on one side of a thick joint, and the tip of the tightening screw whose position is fixed on the other panel is brought into contact with the sloped surface, and then the panel is tightened further. To provide a connection mechanism for heat insulating panels that can be quickly drawn together, their side end surfaces brought into close contact, and easily separated as required.

The present invention will be described below with reference to embodiments shown in the drawings.

FIG. 1 is a front view of two adjacent panels connected.

FIG. 2A is a sectional view taken along the line AA in FIG. 1, and FIG. 2B is a partially enlarged view thereof.

Figure 3 is a diagram of the parts of this mechanism, and A is a perspective view of the joint receiver, and C and A are the joints.

1 is the insulation panel, 2 is the packing, 3 is the joint holder, 4
5 is a joint, and 5 is a tightening screw for bolts, etc.

Joint supports are embedded in three locations on the left and right ends of each insulation panel.

Its position is the same on each panel.

The joint holder is made by fixing the opening of a rectangular square vibro having a depth capable of accommodating about half of the joint to a vertically long rectangular base plate 13 by means such as welding. The area of the plate 13 is about five times the size of the opening, and a female threaded hole 7 into which the tightening screw 5 is screwed is bored in the center of the square pipe shape.

Although it is sufficient for the joint receiver to be made of iron, it may also be one in which the rectangular vibro and the square base plate 13 are integrally molded of hard synthetic resin.

The outer shape of the joint 4 is a rod similar to the hollow part 8 of the square pipe, and the joint 4 is made smaller by the amount of play that allows it to slide, and its length in the left and right direction is slightly more than twice the depth of the hollow part of the joint receiver. It is small, and generally a height of 4 to 5 times the diameter of the tightening screw is sufficient.

In Fig. 3, an inclined surface 9 is formed from a position leaving an appropriate distance from the left and right ends toward the center of the joint at an angle of about 60° with the vertical surface toward the center of the wall thickness. It is sufficient for the length of the bolt to be at least the diameter of the tightening screw in the horizontal direction.

Furthermore, the wall thickness is the same for an appropriate distance from the end of the slope (
After maintaining the parallel front and rear surfaces, the left and right ends have the same thickness.

Its material is made of hard synthetic resin material.

Note that the cross-sectional shape of the joint 4 and the shape of the hollow portion of the joint receiver 3 are not limited to square shapes, and may be polygonal shapes such as hexagons or circular shapes.

When the cross section is circular, key grooves and keys may be provided in the longitudinal direction of the circumference in order to prevent the joint receiver and the joint from rotating relative to each other.

Next, we will outline how to use the present invention.

As shown in FIG. 2, the panel is composed of a pair of outer and outer panels and a heat insulating material.

In the example, what is filled between them is a polyurethane insulation material filled by foam injection, but prior to foam injection, the joint is inserted into the joint using a jig equipped with a protrusion that is inserted into the joint receiving hollow part 8. After supporting and fixing the receiver at a predetermined position and similarly providing a pipe corresponding to the box spanner insertion hole 12 for rotating the tightening screw at a predetermined position on one side of the outer panel 10, polyurethane is foamed and injected.

As mentioned above, the joint support is provided with the base plate 13 having a large area at its base, so that it is extremely firmly fixed within the panel.

Next, at the left and right ends of the two panels, insert the joints into each other's joint receivers, and after erecting the two panels closely, place a plate-shaped rubber gasket with a thickness of about 6 m/m between the ends of both panels. When the tightening screw is tightened with a wrench while it is interposed, its tip hits the inclined surface 9 of the joint.

When the three screws on each of the adjacent panels are further tightened, the tips of the screws are spherical, so they slide on the slope, and the screws 5 and 5' face each other with the gasket in between.
By shortening the distance, the panels are indirectly pulled together, and the 6 m/m rubber gasket is compressed to a thickness of about 3 m/m, and both panels are brought into perfect contact with each other.

The dotted line in the enlarged view indicates the state.

On the other hand, to separate a pair of panels that have been pulled together in the opposite direction, simply turn the tightening screw in the opposite direction, return it to its original position, and pull out the joint from one panel.

In addition, as for the packing for refrigerator-freezers, there are various methods such as interposing the packing only in the part near the two metal outer plates, insulating the middle part with air, or further sealing the surface, and applying other prior art techniques. things are available.
