Description

The present invention mainly relates to a door lock device for a cabinet for storing electrical and electronic equipment.

By operating the handle attached to the door of the electrical / electronic equipment storage cabinet, a stopper that is locked or released is fixed to the rotating shaft of the handle penetrating the door in conjunction with the movement of the rotating shaft. A protective cap may be attached to the clasp for the purpose of preventing scratches and rattling caused by contact with a locking surface that engages the main body of the cabinet when the handle is rotated (see Patent Document 1).

In addition, as shown in FIG. 5, as a structure similar to the structure of the door lock device for the electrical and electronic equipment storage cabinet described in Patent Document 1, as shown in FIG. The distance between the mounting surface of the clasp connected to the rotating shaft of the main body and the locking surface of the main body to which the protective cap locks may change and cause a difference.

For example, in the structure of a conventional door lock device for a storage cabinet for electric and electronic equipment as shown in Patent Document 1 or FIG. 5, the mounting surface 6 of the clasp 4 connected to the rotating shaft of the handle 3 and the conventional protective cap 21. When the distance H with the locking surface 15 of the main body 1 that is locked changes and there is a difference, it is necessary to stock the stoppers 4 of each size corresponding to the distance H, which is expensive. there were.

The present invention aims to eliminate the above-mentioned problems and to halve the types of clasps.

A protective cap that is connected to a rotating shaft of a handle attached to a cabinet door and engages with a locking surface of a main body of the cabinet and is attached to a clasp that is locked or released by operation of the handle. And the thickness of the second surface is changed so that both surfaces can be mounted.

As described above, according to the present invention, the first surface of the protective cap and the second surface of the protective cap that are attached to the side of the catch portion of the clasp that is connected to the rotating shaft of the handle and is locked or released by the operation of the handle attached to the door. By changing the thickness of the surface and making the first surface and the second surface both locking surfaces, it was caused by the structure of the cabinet, the type of handle used, or the distance of the clasp that changes depending on the combination of various cabinets and handles. Can handle the difference. That is, the stopper plate is configured such that the first surface and the second surface both serve as locking surfaces by making the thicknesses of the first surface and the second surface of the protective cap correspond to the difference generated in the distance of the stopper plate. By attaching to the side of the hook, the type of clasp is halved compared to the conventional case, and the effect of simplifying inventory management and reducing costs can be improved.

Hereinafter, a preferred embodiment of the present invention will be described with reference to FIGS.

FIG. 1 and FIG. 2 show a state in which a protective cap 9 is attached to a hooking portion side 7 of a clasp 4 that is connected to a rotating shaft of a handle 3 that is operated when the door 2 is opened and closed and is locked or released. It is a cross-sectional view of the clasp structure. FIG. 1 shows the case where the protective cap 9 locked to the locking surface 15 of the main body 1 is the first surface 9a, and FIG. 2 shows the case where the protective cap 9 is the second surface 9b in the same state as described above. Yes. As shown in FIGS. 1 and 2, depending on the structure of the cabinet, the type of handle 3 used, or the combination of various cabinets and the handle 3, the mounting surface 6 of the clasp 4 connected to the rotating shaft of the handle 3 and the protective cap 9 are provided. The distance from the locking surface 15 of the main body 1 to be locked changes like Ha and Hb, resulting in a difference.

FIG. 3 is a cross-sectional view showing the relationship between the stopper 4 and the protective cap 9. The hollow portion 11 provided on the mounting surface 10 of the protective cap 9 is mounted from the hook portion side 7 of the stopper 4. At that time, the protrusion 12 provided inside the protective cap 9 fits into the opening 8 of the stopper 4, so that the protective cap 9 does not come off from the stopper 4, and the first surface of the protective cap 9 and the second surface Even when the surface is changed, the protrusion 12 does not fit into the opening 8. In addition, by attaching the first surface 9a shown in FIG. 3A with the thickness of each of the protective caps 9a and the second surface 9b shown in FIG. The handle has a clasp structure that can cope with a changing difference such as the distances Ha and Hb.

As shown in FIG. 4, the door 2 is opened or closed by locking or releasing the clasp 4 connected to the rotating shaft of the handle 3 that penetrates the door by operating the handle 3. The clasp 4 connected to the rotating shaft of the handle 3 first comes into contact with the locking surface 15 of the main body 1 by the contact portion 13 of the protective cap 9, and further moves the handle 3 in the direction of the arrow, whereby the contact surface 14 Is slid under the locking surface 15 of the main body 1 and the door 2 is closed. Further, the abutting portion 13 is formed in a shape that has a left-right symmetrical angle and an inclined surface, and the abutting surface 14 is formed in an arc shape so that it does not get caught when sliding into the inner surface of the main body 1. Further, by operating the handle 3, the clasp 4 is released by moving away from the locking surface 15 of the cabinet 1, and the door is opened.

The protective cap 9 attached to the clasp 4 is made of a self-lubricating resin molded product, so that the locking surface 15 of the cabinet body 1 can be easily slipped when the handle 3 is rotated. It has a structure that facilitates dynamic operation. Examples of the resin molded product include a tetrafluoroethylene resin excellent in heat resistance, chemical resistance, electrical insulation, non-adhesiveness, low friction, etc., a polyacetal resin excellent in fatigue resistance, or a tough and durable material. There are polyamide resins with excellent wear and chemical resistance.

It is a cross-sectional view of the clasp structure of the handle showing a state in which the first surface is locked to the main body when the protective cap of the present invention is mounted. It is a cross-sectional view of the clasp structure of the handle showing a state in which the second surface is locked to the main body when the protective cap of the present invention is mounted. It is sectional drawing showing the relationship between a protective cap and a clasp. (A) Cross-sectional view showing the process of attaching the first surface of the protective cap to the clasp (b) Cross-sectional view showing the process of attaching the second surface of the protective cap to the clasp It is a detailed perspective view inside a cabinet showing a state where a clasp connected to a handle is locked. It is a cross-sectional view of a clasp structure of a handle when a conventional protective cap is mounted.
