Abstract

PURPOSE:To simplify a job for alignment at the time of time of assembling two parts with a fitting part each. CONSTITUTION:A lower hinge pin 1a attached to a door 1 is made longer than an upper hinge pin 1b and, after the lower hinge pin 1a is inserted into a lower hinge 2a attached a box body 2 in proper depth previously, the upper hinge pin 1b is made so as to be insertable into an upper hinge 2b installed in response to that. With this constitution, at the time of assembly operation of two parts, it is positioned at each one spot up and down, so that attachment of the door to the box body becomes facilitated.

Description

Detailed Description of the Invention

[0001]

BACKGROUND OF THE INVENTION 1. Field of the Invention The present invention relates to an assembly structure for a structure in which two parts are fitted into each other and assembled.

[0002]

2. Description of the Related Art FIG. 4 is a side view of a structure in which a door is fitted into a housing and then assembled, that is, a hinge structure of a housing having a conventional openable door. In the drawing, 1 is a door, 1a and 1b are doors. Attached hinge pins, 2 are housing bodies, 2a, 2
Reference numeral b indicates a hinge attached to the housing body.

Next, the assembling operation will be described. When the door 1 is attached to the housing main body 2, the lower ends of the upper and lower hinge pins 1a and 1b are simultaneously aligned with the center of the insertion holes at the upper ends of the upper and lower hinges 2a and 2b, and then the door 1 is dropped downward to assemble.

[0004]

According to the conventional door hinge mounting structure of this kind, the door is mounted on the housing main body after aligning the centers of the insertion holes of the hinge pin lower end and the hinge upper end at a plurality of positions at the respective positions at the same time. Since it is necessary, there is a problem that the simultaneous alignment work is troublesome.

The present invention has been made in order to solve the above-mentioned problems, and an object thereof is to obtain a structure which can be assembled with good workability with a time without simultaneously aligning a plurality of connecting works. There is.

[0006]

The door hinge mounting structure according to the present invention is such that the lengths of the upper and lower hinge pins are changed.

In the assembly case with mounting pins according to the present invention, the lengths of the left and right guide pins are changed.

The pair of upper and lower assembly cases according to the present invention is formed by inclining one end face facing the opening.

[0009]

In the present invention, the lower hinge pin can be inserted into the mating hinge first, and then the upper hinge pin can be inserted into the corresponding hinge, which facilitates the positioning work.

Further, in the present invention, the long guide pin on one side can be inserted into the mating hole to a certain depth, and then the other short guide pin can be inserted.

Further, according to the present invention, one side surface of the inclined case can be first aligned with one side surface of the other case, and then the other side can be sequentially fitted by using this as a guide, so that the alignment can be easily performed. .

【Example】

Example 1. An embodiment of the present invention will be described below with reference to the drawings. FIG. 1 is a perspective view a and a side view b of a housing having an opening / closing door, in which 1 is a door, 1a and 1b are upper and lower hinge pins attached to the door, 2 is a housing body, 2a,
2b are upper and lower hinges attached to the housing body 2,
The lengths of the upper and lower hinge pins 1a and 1b are set differently, that is, the lower hinge pin 1a is formed longer.

Next, the assembling operation will be described. Door 1
When attaching the lower hinge pin 1 to the housing body 2, first insert the lower end of the longer lower hinge pin 1 into the center of the insertion hole at the lower end of the lower hinge 2a and insert it to an appropriate depth, and then attach the lower end of the upper hinge pin 1b to the upper part. The hinge 1 is aligned with the center of the insertion hole at the lower end of the hinge 2b, and then the door 1 is dropped into the housing main body 2 to be connected to each other.

Example 2. In the above embodiment, an example of the door mounting structure to the housing is shown, but since the upper case 3 and the lower case 4 are combined as shown in FIG. 2, the guide pins having different heights are provided at the four corners of the lower case 4. A configuration in which 4a and 4b (4a> 4b) are provided upright may be used. Incidentally, 3a and 3b are insertion holes provided corresponding to the guide pins 4a and 4b. This embodiment has the effect of facilitating the combination of the horizontal or vertical surfaces following the guide pins of the two parts.

Further, in Embodiments 1 and 2, the number of fitting places is not limited to the number shown in this embodiment, and the same effect can be obtained at any place.

Embodiment 3. FIG. 3 shows a third embodiment of the present invention. In order to combine the upper case 5 and the lower case 6 with each other, the lower end opening 5a of the upper case 5 is formed to be inclined. It makes it easy to assemble the upper case by vertically lowering it from above and fitting it into the case. That is, in this case, when the upper case 5 is vertically lowered, one side 5b thereof is first fitted into the opposite one side 6b of the lower case 6 as shown in FIG. 8B, which serves as a guide and the right side of the figure is sequentially fitted. Will be combined, so
Positioning work becomes easy.

[0017]

As described above, according to the present invention, in the fitting structure of two parts, it is sufficient to position the upper and lower parts one by one with a simple structure in which the fitting part is provided with a step or an inclination. It has the effect of being dramatically easier.
