Here, the long hole is formed in a shape corresponding to the shape of the clamp, it is preferable to form a predetermined size larger so that the clamp can be inserted.

Hereinafter, with reference to the drawings will be described in detail an embodiment of the present invention. In the description of the present specification, in adding reference numerals to the components of each drawing, it is noted that the same reference numerals are used for the same components, even if shown on different drawings.

1 is a perspective view showing the door lock device separated from the door according to the present invention.

The door locking device 10 according to the present invention, as shown in Figure 1, is used to limit the opening and closing of the bellows type door movably installed in the door frame.

The bellows-shaped door is movably coupled to a plurality of members alternately coupled on the frame 2. In addition, the frame 2 is movably coupled to the guide rail 4 installed in the direction crossing the entrance and exit. Accordingly, the bellows-type door moves the frame 2 to open and close the doorway.

The door locking device 10 is installed in the bracket 12 on the front of the lock bundle 20, the lock bundle 20 is installed inside the door frame 2 by the bracket 12. The lock bundle 20 is rotated by the combination of the key 30, the shaft portion 24 is protruded in the center thereof. In addition, a fastening hole may be formed in the door frame 2 to fix the bracket 12. The bracket 12 may be coupled to the fastening hole with a bolt or other fastening member.

In addition, the door frame 2 is formed with a penetrating portion 3 of a predetermined size so that the shaft portion 24 can pass therethrough. In addition, the end portion of the shaft portion 24 is provided with a fixing clamp 26 extending in the longitudinal direction. The clamp 26 rotates together with the shaft portion 24 when the key 30 inserted into the lock bundle 20 rotates.

The door locking structure using the door locking device 10 is coupled to the door frame to limit the opening and closing of the door.

To this end, the door frame is formed with a long hole (5) extending in the longitudinal direction at a position corresponding to the clamp.

In addition, when the door locking device 10 restricts the opening and closing of the door, the clamp 26 is inserted into the long hole 5, and then, when the key 30 is rotated, the shaft part 24 and the The clamp 26 provided in the shaft part 24 rotates.

Then, the rear side of the fixing clamp 26 is caught inside the door frame to prevent the door from opening.

Here, the fixing clamp 26 is made of a long rod member formed in one end of the shaft portion 24 in the longitudinal direction, it may be integrally formed on one end of the shaft portion (24).

At this time, the long hole 5 is formed in a shape corresponding to the shape of the clamp 26, it is formed a predetermined size larger than the shape. Accordingly, the clamp 26 may be smoothly inserted into the long hole (5).

2 is a cross-sectional view of the locked state of the door lock device according to the present invention, Figure 3 (a) and (b) is a cross-sectional view of the line A-A, B-B of FIG.

The lock bundle 20 includes a fixed bundle 28 penetrating the center portion, the rotating bundle 22 is rotatably coupled to the through portion of the fixed bundle 28. In addition, the rotary bundle 22 has a groove portion 23 is formed in the center, the rotation is made by the key 30 is inserted into the groove portion (23). In addition, the fixed bundle 28 may include a door fitting portion for rotatably combining the rotary bundle 22 according to the key 30 inserted into the groove 23.

The door fitting portion has a plurality of insertion grooves 32 are formed in the fixing bundle 28 in a direction orthogonal to the key 30, and each of the insertion grooves 32 is fitted with an intermediate pin 34. In addition, between the bottom of the insertion groove 32 and the intermediate pin 34 is supported on the bottom of the insertion groove 32 and the spring 35 is provided to elastically press the intermediate pin (34). The door fitting further includes a key pin 36 pressed by the intermediate pin 34 and contacting the hill or valley of the key 30.

The innermost side of the door fitting portion is formed with a cutout portion 37 which cuts out the outer side where the intermediate pin 34 spans by 90 degrees, and thus the innermost middle pin 34 when the rotating bundle 22 is rotated. It moves along the cutout 37. In addition, the rotation bundle 22 is the rotation of the middle pin 34 of the innermost is caught by the cutout 37 is limited.

Figure 4 is a cross-sectional view of the open state of the door lock device according to the present invention, Figure 5 is a cross-sectional view of the C-C, D-D line of Figure 4, referring to this operation of the door lock device as follows.

First, the process of locking the door pulls the frame 2 of the door. At this time, the clamp 26 of the door locking device 10 is inserted into the long hole 5 of the guide rail 4 installed in the door frame. And, for the operation of the door lock device 10, the key 30 is inserted into the groove 23 of the rotary bundle 22. In this way, when the key 30 is inserted, the key pin 36 is pressed by the unevenness of the key 30. The key pin 36 retracts the intermediate pin 34. In addition, the intermediate pins 34, one end of which is caught in the rotary bundle 22, retreat and move toward the insertion groove side of the fixed bundle 28. Then, when the intermediate pin 34 is completely separated from the rotary bundle 22, the rotary bundle 22 is rotatable.

Then, when the key 30 is rotated, the rotary bundle 22 rotates, and thereby the fixing clamp 26 installed on the shaft portion 24 of the rotary bundle 22 rotates.

At this time, on the other hand, the middle pin 34 located on the innermost side of the rotary bundle 22 moves along the cutout 37 during the rotation of the rotary bundle 22, the rotary bundle 22 is 90 degrees When rotated, the intermediate pin 34 is caught by the cutout 37 to limit the rotation.

In addition, the clamp 26 is to rotate the intermediate pin 34 by the cut angle of the cutout portion, that is, 90 degrees. Accordingly, the clamp 26 restricts the opening and closing of the door in a state of being inserted into the long hole 5.

In the embodiment of the present invention, the clamp 26 is described as being formed in a rod shape, it is also possible to change the shape. For example, referring to FIGS. 6A and 6B, which illustrate cross-sectional views of a clamp of a door locking device according to another embodiment of the present invention, are as follows.

The door locking device 10 has an insertion hole 124a formed in the shaft portion 24, and a first spiral portion is formed inside the insertion hole 124a. In addition, a clamp 126 is inserted into the pipe guide rail 3. The fastener 26 is fastened by a second spiral portion formed to correspond to the first spiral portion at the intermediate portion.

At this time, the door locking device 10, as shown in Figure 6 (a), the stepped portion 126a is formed at a predetermined depth inside the insertion hole 124a, is supported on one side of the clamp 126. . Thus, the clamp 126 is inserted within a predetermined depth from the shaft portion 24, so that both ends of the clamp 126 are symmetrically coupled to each other about the shaft portion 24.

On the other hand, the door locking device 10, as shown in Figure 6 (b), it is also possible that the stepped portion 126a is formed on the outer side of the clamp 26.

In addition, the end of the fixing clamp 26 is further formed with a straight or cross-shaped fixing groove 128, by inserting a flat or Phillips screwdriver into the fixing groove 128 can easily rotate the fixing clamp 26.

As described above with reference to the door lock device and the door lock structure using the same as described above, the present invention is not limited by the embodiments and drawings described above, this invention belongs to the utility model registration claims Of course, various modifications and variations can be made by those skilled in the art.

The door lock device and the door lock structure using the same according to the present invention is configured as described above is combined with the door lock to limit the opening and closing of the door is convenient to limit the opening and closing of the door, it is necessary to provide a separate door opening and closing tool There is no. In addition, there is an advantage that the internal configuration is simple and easy to manufacture.
