Description

[Detailed Description of the Invention] [Industrial Application Field] The present invention relates to a door device for opening and closing an opening of a device such as a logic analyzer, and particularly relates to a door device that automatically returns.

[Prior Art] FIG. 6 shows a rear view of a conventional logic analyzer, and FIG. 7 shows a part of a cross-sectional view taken along line A-A' in FIG.

That is, a conventional logic analyzer is provided with a plurality of openings 2 into which connectors 1 are inserted and an exhaust port 3 on the back surface thereof. A connector 1 is inserted into each of the openings 2 to connect the logic analyzer to other electronic equipment. Further, an exhaust blower is provided inside the exhaust port 3 to exhaust the inside of the logic analyzer and cool the inside of the logic analyzer.

[Problems to be Solved by the Invention] However, if the logic analyzer has an opening 2 and an exhaust port 3 on the back side, when the inside of the logic analyzer is exhausted, the air that entered through the opening 2 will directly flow to the exhaust port 3. The disadvantage is that the cooling effect deteriorates because the inside of the logic analyzer cannot be sufficiently ventilated. Furthermore, if there is an opening 2 on the back side of the logic analyzer, there is a possibility that dust or the like may enter through this opening 2.

Therefore, opening 2 on the back of the logic analyzer
It is conceivable to provide a door that can be opened and closed freely and that automatically returns and closes, but in this case, the door,
It requires separate parts such as the shaft, bearing, return coil spring, etc., and has the disadvantage that the number of parts is large, the structure is complicated, and assembly and installation are complicated.

This idea was made in view of the above circumstances.
To provide an automatic return type door device that has a simple structure, can reduce the number of parts, and can be easily assembled and installed.

[Means and effects for solving the problems] In order to achieve the above object, the present invention includes a bearing part and a return part receiving part provided in a housing body having an opening, and a return part receiving part inserted into the bearing part. a door body integrally provided with a shaft portion inserted into the bearing portion and a return portion inserted into the return portion receiving portion; and a door body configured to press the shaft portion inserted into the bearing portion and the return portion inserted into the return portion receiving portion. By integrally providing the shaft portion and the return portion in the door body, and integrally providing the bearing portion and the return portion receiving portion in the casing body, Since the door body can be attached to the casing body simply by pressing the shaft part and return part of the door body with a return spring, the number of parts is reduced, the structure is simple, and assembly and installation are extremely easy.

[Embodiment] An embodiment of the present invention will be described in detail below with reference to the drawings.

That is, FIGS. 1 to 5 show one embodiment of the present invention, FIG. 1 is a front view of the door device, and FIG. 2 is a front view of the door device.
3 is a front view showing the main body of the casing in Fig. 1, Fig. 4 a is a front view of the door main body in Fig. 4c is an enlarged end view of FIG. 4b, and FIG. 5 is a side view of FIG. 3. That is, as shown in FIG. 3, the housing body 4 is provided with an opening 5 approximately in the center, and around this opening 5 there is a bearing part 6 formed in a concave shape lower than other parts and a return part. The receiving portion 7 is provided in a stepped manner. 8 is a spring mounting hole. Further, a return portion 10 and a shaft portion 11 are integrally provided at both ends of one side of the door body 9, respectively. The shaft portion 11 is formed into a substantially cylindrical shape, and the return portion 10 has an arcuate surface extending rearward and upward from the front surface of the shaft portion 11 . After inserting the shaft portion 11 of the door body 9 into the bearing portion 6 of the casing body 4 and inserting the return portion 10 into the return portion receiving portion 7, a plate-shaped return spring 12 is inserted as shown in FIG. is attached so as to press the shaft portion 11 and the return portion 10. The return spring 12 is formed into a substantially U-shape as shown by diagonal lines in FIG.

That is, the door device as shown in FIG. 1 is provided with the front side facing inside the back surface of the logic analyzer, for example. Then, as shown in FIG.
3, and this connector 13 connects the logic
Connect the analyzer and other electronic devices. In this case, two door bodies 9 are provided for one opening 5 of the casing body 4, so that the door bodies 9 are double-opened. The door body 9 is opened and closed by the rotation of the shaft portion 11 within the bearing portion 6, but since the return portion 10 is pressed by the return spring 12, a force is always applied to the door body 9 in the closing direction. . In this case, as shown in FIG. 4d, even if the door body 9 is pressed in the direction of arrow C by the connector, the shaft part 11 is pressed in the direction of arrow D by the return spring 12, so that the shaft part 11 is It will not be removed from Part 6. In addition,
Since the door body 9 into which the connector is not inserted is closed by the action of the return portion 10 and the return spring 12, there is no possibility of dust etc. entering or insufficient ventilation inside the logic analyzer during exhaust.

[Effects of the invention] As described above, according to the invention, the shaft part and the return part are integrally provided in the door body, and the bearing part and the return part receiving part are integrally provided in the casing body, so the number of parts can be reduced. It is easy to assemble by attaching a return spring to press the return part and the shaft part.
Installation becomes much easier, especially in tight spaces. Furthermore, since the mechanism for attaching and returning the door body is integrally formed with the door body, the structure can be simplified.
