DETAILED DESCRIPTION OF THE PREFERRED EMBODIMENTS Hereinafter, preferred embodiments of the present invention will be described in detail with reference to the accompanying drawings.

Referring to FIG. 2, a push-pull door 10 is formed on a cover body 100, and a push-pull door lock is operated by operating a motis (not shown) do.

7, the push plate 10 is connected to the inner side of the cover body 100 through a hinge portion 110 and presses the lower end side of the push plate 10 to push the push plate 10 toward the cover body 100 And has a pressed configuration.

3, the pushing post 12 and the pressure plate 10 are protruded from the inner surface of the lower end of the pressure plate 10 by a predetermined length at a predetermined interval. The double pushing post 12 is installed at a position where it abuts against the pushing end 21 of the vertical gear member 20 provided at the lower end and the pushing post 12 has a spring (not shown) The pressing plate 10 is retracted when the pressing plate 10 is pressed, and the pressing plate 10 is returned to its original position by the elastic force.

The vertical gear member 20 is installed such that the pressing tip 21 is in contact with the pressing post 12 so that when the user presses the pressing plate 10, the pressing plate 10 is lowered, So that the vertical gear member 20 is rotated.

8 and 9, the vertical gear member 20 is gear-connected (connected in a bevel gear type) perpendicular to the motis pivotal member 30, The rotation shaft 22 penetrates and is rotatably connected to the rotation of the motor 30 perpendicular to the rotation axis 22. At this time, the rotary shaft 22 has one end penetrated through the boss portion 130 formed in the cover body 100 and the other end fixed to the side surface of the cover body 100 by the fixing piece 150, And the vertical gear member 20 can be interlocked by being gear-connected in the form of a bevel gear to the motis pivoting member 30. [

On the other hand, when the motor shaft 30 is rotated by the operation shaft 35 mounted on the motor shaft 30, the operation shaft 35 is rotated to drive the dead bolt and the latch bolt .

When the push plate 10 is lowered by the user pressing the push plate 10 and the pushing post 11 pushes the pushing end 21 of the vertical gear member 20 to rotate the vertical pushing member 10, And the motor shaft 30 connected to the gear shaft 30 are interlocked with each other, and the actuating shaft 35 connected to the motor shaft 30 actuates the motors to enable the setting and releasing of the motors.

That is, according to the present invention, the pressing force transmitted to the pressure plate 10 rotates the vertical gear member 20 and rotates the mothis rotary body 30 connected thereto, so that the operation of the mothy rotary body 30 is enabled with a simple structure It is possible to ensure a precise driving force without dispersing the pressing force of the pressure plate 10, and it is possible to reduce the number of parts and improve the installation performance.

In addition, the vertical gear member 20 is not structured with a gear as a whole, but has a structure in which a gear portion 23 (semicircular shape) is formed only in a part of the operating range and a pressing tip 21 is abutted against the pressing post 12 .

On the other hand, it is preferable that the Mortice pivoting body 30 is configured to be rotated at a predetermined angle by the torsion spring 50 fixed to the lower plate 40 and return to the original position. That is, when the pushing post 10 presses the pushing plate 10 and the pushing post 12 pushes the pushing end 21 of the vertical gear member 20 to rotate, the motive pivoting member 30 connected to the pushing post 10 rotates. (See FIG. 6) by the elastic force of the torsion spring 50 when the push plate 10 returns to its original position due to weakening of the force applied to the stop plate 10 (see FIG. 6). To this end, a locking block 35 for supporting one end of the torsion spring 50 is formed in the mottility pivotal body 30, and an insertion groove 36 into which a driving shaft (not shown) is inserted is formed Reference).

 The connection structure of the push-pull door lock according to the present invention constructed as described above includes a pushing post 12 having a predetermined length formed at a lower portion of the pushing plate 10. When the pushing plate 10 is lowered, The pressing tip 21 of the main body 20 is lowered to rotate the vertical gear member 20 and the motive pivot member 30 provided in the bevel gear type is rotated (interlocked) with the vertical gear member 20, Can be achieved.

Accordingly, the pressing force applied to the pressure plate 10 is transmitted directly through the vertical gear member 20 without being lost, and the motice rotating body 30 can be directly rotated to operate the motice. In addition, since the pushing plate 10 is connected to the motors pivoting body 30 via the vertical gear member 20, it is possible to directly remove the other driving parts (parts for link connection) It is possible to minimize the number of parts, thereby reducing the cost of the product and improving the reliability of the operation.

 In addition, only the vertical gear member 20 is connected between the pressure plate 10 and the Mortise rotator 30, so that the operation of pressing the pressure plate 10 directly rotates the vertical gear member 20 to rotate the Mortice rotator 30 Since it is a rotating structure, intuitive operation is possible, and operation reliability can be guaranteed.

In addition, since a separate link structure is not required, the number of components for connection can be remarkably reduced, and a factor causing malfunction can be reduced. By being configured to operate in a vertical direction (bevel gear type), it is possible to reduce the clearance occurring in the conventional link connection structure and minimize the loss of force occurring between the links.

While the present invention has been particularly shown and described with reference to the particular embodiments thereof, it is to be understood that the invention is not limited to the disclosed embodiments, but, on the contrary, It will be understood by those skilled in the art that various changes in form and details may be made therein without departing from the spirit and scope of the invention.
