Description

[Detailed description of the invention] [Field of industrial application] The present invention relates to a connection structure for equipment, and is particularly suitable for assembling plate-shaped parts such as a plastic case and a plastic cover by connecting them to each other in abutting state. Regarding the connection structure of equipment.

[Conventional technology]

When connecting two plate-shaped members, a method is generally adopted in which the connecting portions of both members are directly overlapped and joined by screwing or the like.

[The problem that the idea aims to solve]

However, in the conventional connection structure between the plate-shaped parts, the peripheral parts are overlapped and fastened with bolts and nuts as described above, so when fastening the parts, it is necessary to work from both sides.

In addition, since the peripheral parts are overlapped, a difference in plate thickness occurs at the connecting part, which makes the appearance undesirable.On the other hand, in order to solve this problem, forming a thin stepped part on both members that sit on each other takes into consideration the strength of the connecting part. There are disadvantages such as the need to design the whole thing thickly.

Such a conventional connection structure is disclosed in, for example, Japanese Patent Application Laid-open No. 1983-
97575 and Japanese Patent Publication No. 60-26754.

Therefore, a method has been proposed in which two plate-like members (covers, cases, etc.) are connected with their end surfaces abutted against each other.

However, in the conventional end face butt connection structure,
In general, since the peripheral edge portions are groove-fitted, in the case of parts such as plastic covers where some degree of molding distortion is unavoidable, considerable effort is required to assemble the parts, which is also inconvenient in terms of workability.

[Purpose of the invention] The purpose of the invention is to solve the above-mentioned disadvantages of the prior art, and to connect the peripheral plate-like parts of two plastic molded products in a butt state with a simple structure and to connect both members from one side. To provide an equipment connecting structure which can be easily connected in a detachable manner by a simple operation and can be assembled reliably with no gap between the end faces of both members and in a state with good appearance.

[Means to achieve the purpose]

The equipment connection structure of the present invention integrates a bifurcated fitting part that forms an insertion space with an interval corresponding to the thickness of the peripheral plate-shaped parts of two plastic molded products and the base end of each fitting part. A notch of a predetermined width is formed on the joint end surface of each plate-shaped part of the plastic molded parts to be connected, and each of the joining members By pushing the edge of the notch of each plate-shaped part into the fitting part and tightly fitting it, and by positioning the intermediate part in the notch, each plate-shaped part can be attached to both sides at the fitting part. The above object is achieved by holding the plate-like parts under pressure and connecting them in an abutting state with the end surfaces of each plate-like part in contact with each other.
