In addition, the fixing member B of the present invention includes indoor and office furniture, fire hydrant, EPS room, and the like. In addition to the fixing member B, the door fixing device 10 ) Can be used. 1, the fixing member B may be made of a magnetic material having a magnetic property as a whole. In the case of a non-magnetic substance, an attachment member B 'made of a magnetic material is provided on one side of the opening portion of the fixing member B It may be additionally provided. When the opening portion is closed by the door S, the door fixing device 10 according to the present invention is brought into contact with the attachment member B 'to fix the closing operation of the door S.

In order to realize the above feature, the door locking device 10 according to the present invention comprises a clip 100 and a magnet 200 as shown in FIGS.

At this time, the clip 100 is bent in a substantially " C " shape and the fitting opening 110 is formed inwardly so as to be detachably fitted to the outer circumference of the door S. [

More specifically, the clip 100 forms an outer shape by vertically bending sheet metal cut to a predetermined size many times. Although the clip 100 is shown in a state where the clip 100 is fitted to the outer circumferential edge of the side surface of the door S, the clip S may be fitted to the upper surface or the lower surface of the door S as necessary.

In addition, although one clip 100 is inserted into the door S in this embodiment, it is needless to say that a plurality of the clips 100 can be used as needed.

The clip 100 is folded so that the front plate 120, the top plate 130, and the rear plate 140 are integrally formed as shown in FIGS. 2A and 2B. The front plate 120, the upper plate 130 and the rear plate 140 are both formed in a thin plate shape so that the front plate 120 and the rear plate 140 are in contact with the front and rear surfaces of the door S, The clip 100 can be fitted in the door S. [

At this time, the clip 100 includes a top plate 130 that vertically bends and extends from the top of the plate 120, and a bending extension 130 that vertically extends downward from the top plate 130 in parallel with the front plate 120. [ And the rear plate 140 is formed with a magnet 200 to be described later.

As shown in FIG. 5, at least one of the front plate 120 and the rear plate 140 has a retaining protrusion 150 protruding toward the fitting hole 110.

When the clip 100 is to be removed from the door S while holding the front plate 120 and the rear plate 140 of the clip 100, the clip 100 acts as a compressive force holding the door S The clip 100 can not be easily removed from the door S, thereby preventing the door fixing device 10 from being stolen. A method of removing the clip 100 from the door S will be described later.

Accordingly, in the conventional door locking device, the door locking device may be detached from the door due to centrifugal force or other external force during operation of opening and closing the door. Alternatively, the door locking device 10 according to the present invention may be detached from the door S It is a configuration that can be maintained at all times.

The clip 100 may further include a plurality of grip protrusions 160 protruding from the back plate 140 to grip the outer circumference of the magnet 200 when the magnet 200 is attached to the clip 100 Lt; / RTI >

2 to 3, it is preferable that a plurality of the protrusions 160 protrude so as to sufficiently grasp the periphery of the magnet 200. By grasping the outer circumference of the magnet 200 from all directions, 200) are protected from breaking.

When the door S is repeatedly opened and closed, the magnet 200 is repeatedly brought into contact with the attaching member B 'to cause the magnet 200 to be broken. However, when the gripping protrusion 160 contacts the magnet 200 It is possible to prevent the magnet 200 from being broken beforehand.

In the meantime, the magnet 200 is configured to be easily replaced by the structure in which the grip protrusion 160 grasps a part of the rim of the magnet 200 even if the magnet 200 is broken due to an unavoidable reason.

4 and 5, the rear plate 140 may be formed with a removal groove 141 which penetrates the rear plate 140 in the front-rear direction so as to facilitate the replacement of the magnet 200 .
