Description

Hinges with stopper function "

The present invention relates to an enclosure hinge having a stopper function. More particularly, the present invention relates to an enclosure hinge having a stopper function for engaging a door with an enclosure using a hinge having a stopper function therein, To a hinge.

BACKGROUND ART [0002] In general, an electric distribution panel is installed in a building equipped with a power plant, a substation or various electric facilities to facilitate the opening and closing of electric circuits and the control of electric devices connected thereto. .

The door of the enclosure where such a switchboard is installed is arranged with various indicators and instruments of the switchboard, and its load is considerable. Accordingly, the door of the enclosure generally uses a rigid hinge to withstand a large load, and a door stopper is mounted so as not to interfere with the operation by the shaking of the door due to the body contact of the worker.

However, in case of installing the enclosure door by such a structure, the hinge for turning the door of the enclosure and the door stopper for fixing the door must be individually installed. Therefore, in case of a workplace having a large number of switchboards such as a substation, a power plant, There is a problem that the installation cost is excessively required and the installation work is not easy.

[Patent Document 1] Korean Utility Model Registration No. 20-0298713

In order to solve such a problem, the present invention provides an enclosure hinge having a stopper function to open the door at a constant opening angle when the door is opened by coupling the door to the enclosure using a hinge having a stopper function inside, It has its purpose.

The hinge for the enclosure provided with the stopper function according to the embodiment of the present invention has a shape of 'c' for coupling the door to the enclosure main body so as to be rotatable at a predetermined angle, A fixing member having bolt coupling holes spaced at regular intervals on a side surface thereof and having a shaft hole penetrating the upper and lower end surfaces thereof; And a guide rail groove formed in the longitudinal direction and having a predetermined depth in the longitudinal direction, wherein the guide rail groove is formed in the longitudinal direction and is coupled to the fixing member so as to be exposed at the central portion, ; And a tilting member inserted into the guide rail groove at one side of the side surface and formed with a protrusion that moves along the guide rail groove and pivotally coupled to the exposed central portion of the shaft hole.

As an embodiment related to the present invention, the guide rail groove can be deepened with a constant inclination angle in the direction in which the door is opened.

As an embodiment related to the present invention, an O-ring may be further provided on a surface where the fixing member and the pivoting member are in contact with each other.

According to the present invention, a hinge having a stopper function is used to connect a door to an enclosure so that the door is always opened at a constant opening angle when the door is opened, thereby reducing the installation cost of the enclosure door.

Further, since the installation work of the outer door is facilitated, the work cost and the work force can be reduced, and the production cost can be lowered, thereby making it possible to have a competitive advantage.

In the present invention, terms such as "comprising" or "comprising" and the like should not be construed as encompassing various elements or various steps of the invention, Or may further include additional components or steps.

Hereinafter, exemplary embodiments of the present invention will be described in detail with reference to the accompanying drawings, wherein like reference numerals refer to like or similar elements throughout the several views, and redundant description thereof will be omitted.

1 is a perspective view of an enclosure hinge having a stopper function according to the present invention. 2 is an exploded perspective view of FIG. 3 is a view for explaining a guide rail groove of the shaft rod applied to the present invention. FIG. 4 is a view for explaining another embodiment of the guide rail groove of FIG. 3. FIG. 5 is a cross-sectional view of Fig.

1 and 2, an enclosure hinge 100 for coupling the door to the enclosure body so as to be rotatable at a predetermined angle is provided on the fixing member 110, the tiltable member 120, the shaft rod 130, and the O- 140).

The fixing member 110 has a shape of a 'C' and is formed with a bolt coupling hole (not shown in the figure) spaced at a predetermined interval from the side surface thereof to be coupled to the body of the housing by bolts. The shaft hole 111, Respectively.

The shaft rod 120 is coupled to the shaft hole 111 of the fixing member 110 and is coupled to the fixing member 110 so as to be exposed at the center of the shaft member 120. An insertion groove 121 is formed in the longitudinal direction, A guide rail groove 122 extending in the longitudinal direction and having a predetermined depth in the longitudinal direction is formed.

A groove having a predetermined length is formed at a position spaced apart from a vertical groove (121 in FIG. 3) to which the projection 131 provided on the pivoting member 130 is coupled, A part of the pin 123 is inserted and fitted so as to protrude to the outside.

A groove 113 is formed in the upper surface of the inner side of the shaft hole 111 to which the shaft rod 120 of the fixing member 110 is coupled. When the shaft rod 120 is fitted into the shaft hole 111, So that the shaft rod 120 is fixed to the fixing member 110. In this case, Therefore, it is possible to prevent the shaft 120 from rotating together when the tiltable member 130 rotates about the shaft 120.

4 and 5, the guide rail groove 122 is formed so as to be inclined in a direction in which the door is opened. When the door is closed, the protrusion 131 must be raised upward along the inclined surface, The door will not automatically close.

The tiltable member 130 has a projection 131 which is inserted into the guide rail groove 122 at one side of the side surface and is movable along the guide rail groove 122 and is rotatably coupled to the center portion of the exposed shaft.

The O-ring 140 is provided on a surface where the fixing member 110 and the tiltable member 120 abut and is abraded when the tiltable member 120 rotates about the fixing member 110, So that noise can be removed.

An operation state of the hinge for an enclosure provided with the stopper function configured as described above will be briefly described below.

6 is a view for explaining a hinge operating state in a state in which the door of the enclosure is closed. 7 is a view for explaining a hinge operating state when the door of the enclosure is opened (open).

6, when the door of the enclosure is closed, the protrusion 131 is located in the front of the guide rail groove 122. As shown in FIG. At this time, when the door of the enclosure is opened, the protrusion 131 moves along the guide rail groove 122 by the opening force, and the protrusion 131 moves to the end of the guide rail groove 122 as shown in FIG. The door will no longer open.

4 and 5, since the guide rail groove 122 is formed with an inclination, when the door is opened, the projection 131 is easily opened along the guide rail groove 122 such as the downward path When the door is closed, the protrusion 131 must move along the guide rail groove 122 such as an uphill road, so that the door is not closed with respect to a weak external pressure such as wind.

It will be apparent to those skilled in the art that various modifications and variations can be made in the present invention without departing from the spirit or essential characteristics thereof. Therefore, the embodiments disclosed in the present invention are intended to illustrate rather than limit the scope of the present invention, and the scope of the technical idea of the present invention is not limited by these embodiments. The scope of protection of the present invention should be construed according to the following claims, and all technical ideas within the scope of equivalents should be construed as falling within the scope of the present invention.
