Description

[Detailed Description of the Invention] This invention relates to a panel structure such as panel mounting of a unit frame configured as, for example, refrigeration or air conditioning equipment.

Conventionally, there have been devices of this type as shown in FIGS. 1 and 2.

In the figure, 1 is a frame, 2 is a panel, 3 is a heat insulating member (glass wool, etc.), 4 is a small diameter steel pipe spot welded to the panel 2, 5 is a flat washer, 6 is a screw member such as a machine screw, 7 is a backing plate that replaces the steel pipe 4 and is fixed to the panel 2 by spont welding or the like.

Next, the structure will be explained.

Generally, the panel 2 uses a thin steel plate, so if there is no object inside the tightened part of the panel 2, if the bolt member 6 is tightened too much, that part will dent and become extremely unsightly and lose its commercial value. .

Therefore, as can be seen in FIGS. 1 and 2, a steel pipe 4 or a plate 1 is welded to the panel 2 as a member corresponding to the rising height inside the panel 2.

Since the conventional panel structure is configured as described above,
There was work such as cutting and welding steel pipes, and making and welding plates.

Furthermore, when the panel is removed, there is no way to prevent the screw members from falling off, so they may be lost after removal.

This idea was made in order to eliminate the drawbacks of the conventional ones as mentioned above, and it is a panel structure that installs an elastic member between the panel and the frame to prevent the panel from denting and screws from getting lost. is intended to provide.

An embodiment of this invention will be described below with reference to FIGS. 3 and 4.

FIG. 3 shows a state in which the elastic member 8 is attached to the panel 2 with the screw member 6, and is in a state before being attached to the frame 1.

In FIG. 3, the elastic member 8 is made of, for example, semi-hard rubber and is a cylindrical body with an H-shaped cross section.

Reference numeral 8a denotes a small diameter portion, and the wall thickness of this portion is thinner than other portions, and the through hole of the screw member 6 is made slightly smaller than the screw diameter so that the screw member is held by the elasticity of the rubber.

Reference numeral 8b is a compression margin to withstand the dent in the panel 2 when the screw member is tightened, and also serves to prevent the screw member from loosening due to the reaction at the time of compression.

FIG. 4 shows the panel 2 attached to the frame 1, with the elastic member 8 being compressed.

As can be seen from the above figures, before the panel 2 is attached to the frame 1, the screw member 6 is held by elasticity at the small diameter portion 8a, and when the panel 2 is attached to the frame 1, when the screw member 6 is tightened, the cylindrical portion of the elastic member 8 is compressed to improve hardness and prevent the panel 2 from denting, and also has the effect of preventing the screw member 6 from loosening due to the force acting on the head portion of the screw member 6 due to the reaction of the elasticity.

As described above, according to this invention, since the elastic member is installed between the panel and the frame, the structure of the panel is simplified, and since the installation is extremely simple, it is easy to handle. .

[Brief explanation of the drawing]

1 and 2 are cross-sectional views showing the main parts of a conventional panel structure, FIG. 3 is a cross-sectional view of the main parts of a panel structure according to an embodiment of this invention before tightening, and FIG. FIG. 3 is a cross-sectional view of the main parts when tightened. In the figure, 1 is a frame, 2 is a panel, 3 is a heat insulating member, 4 is a steel pipe, 5 is a flat washer, 6 is a screw member, γ is an L-shaped backing plate, and 8 is an elastic member. Note that the same reference numerals in the figures indicate the same or equivalent parts.

Claims (1)

[Scope of utility model registration request] A frame body, a panel that is fastened to the surface of the frame body with a heat insulating member interposed therebetween, a screw member that is disposed through the panel and fastens the panel to the frame body, and can be compressed and held on the outer periphery of the screw member. A panel structure comprising an elastic member having a small diameter portion and capable of being compressed and interposed between the frame and the panel in a tightening direction.
