Description

Lock device for door

The present invention relates to a door locking device, and more particularly, to a door locking device in which a cover is formed to be engaged with a side of a main body by forming a locking blade from one side of a cover portion downwardly, So that the workability of the door locking device can be greatly improved.

2. Description of the Related Art [0002] Generally, a door locking device is widely used to lock a door, such as a door, a locker, and the like, which is installed in a door of a house, apartment, Is installed at one side of a door such as a doorway or an office door to limit the access to a specific area by keeping the door closed in a specific area or to close a door that is installed at one side of a door such as a cabinet or a locker, .

Here, in the case of a door lock device used to limit access to a specific area, it is necessary to keep the door closed even when a non-entering person intends to enter the specific area. Therefore, when a very stable locking state is required, In the case of a door locking device in which a door is closed in order to shield a specific space while taking a complicated structure, convenience of opening and closing operation of the door, that is, Compared to door locks for restriction, the structure is relatively simple.

1 is a view showing a conventional door locking device.

1, the conventional door locking device 100 includes a main body 110 having a receiving space 111 formed therein and having an upper surface opened to expose the receiving space 111 to the outside and installed at one side of the door, A lock part 120 slidably installed in the receiving space 111 of the main body 110 so as to be slidable in the inside and outside direction of the main body 110 and one side of the lock part 120 being supported on one side of the door frame, A cover member 140 installed on the upper surface of the main body 110 and shielding the receiving space 111, a spring member 130 interposed between the main body 110 and the lock member 120 to provide an elastic force to the lock member 120 in the inner direction of the main body 110, And a handle part 150 rotatably coupled to the cover part 140 and having one side supported on one side of the lock part 120.

In the conventional door locking device 100, one end of the lock part 120 is protruded to the outside of the main body 110 and is supported at one side of the door so as to prevent the door from rotating, thereby maintaining the closed state of the door, The handle portion 150 is rotated so that one side of the handle portion 150 moves the lock portion 120 to the inside of the main body 110 and then the handle portion 150 is pulled in the opening direction of the door Push to open the door.

The conventional door lock device 100 has a screw hole (not shown) formed at one side of the cover part 140 and a bolt member (not shown) passes through a lower side of the main body 110, A plurality of bolt members (not shown) are coupled to the cover unit 140 to couple the cover unit 140 with the main body 110 by coupling the cover unit 140 and the main body 110 by coupling the cover unit 140 to the screw hole (not shown) The cover 140 and the main body 110 need to be screwed to each other, so that the operation is cumbersome, and a considerable time is required for the operation, and the productivity is greatly reduced as the operation time is increased.

The conventional door locking device 100 includes a main body 110 and a through hole 151 at one side of the handle portion 150 to rotatably couple the handle portion 150 to one side of the cover portion 140. [ A drilling process for forming the through hole 151 by the rotation shaft 160 inserted into the through hole 151, a process of injecting the rotation shaft 160 for manufacturing the rotation shaft 160, Since the assembling process for inserting the through hole 151 into the through hole 151 is required, the manufacturing cost is greatly increased due to the complicated process and the workability is remarkably lowered due to the working time required for the process.

In addition, the conventional door locking device 100 rotates the handle portion 150 while resisting the elastic force of the elastic member to open the door in the case of the pivot open type door, and at the same time, So that the opening operation of the door can not be easily performed.
