In addition, in order to prevent torsion and smooth operation of the redirector 1 placed on the base plate 5, a stopper 5 is provided on one side of the base plate 5, and the redirector 1 is guided correctly. The inlet port 51 of the beneficiation post narrowing type is formed, and a guide 52 is provided between both sides of the redirector 1 and the side wall 52 of the base plate 5 to prevent up and down flow when the redirector 10 operates. It was made.

Referring to the operation and effects of the present invention configured as described above in more detail.

First, a hole for locking the lock body 7 is formed in the door to be fixed, and then the lock body 7 is inserted into the body spindles 10 and 10 'protruding into and out of the lock body 7. Attaching the mounting plate (22, 22 ') is fixed to the mounting plate (22, 22') by mounting the spindle (12, 12 ') is fixed by using a set screw.

At this time, the first thing to be adjusted should be the width between the inner and outer mounting plates (22, 22 ') to match the thickness of the door.

It is the outer fixing plate 31 'coupled with the screw 5' formed on the outer side of the lock body 7 after breaking the casing port 33 and the outer fixing plate 31 'fixed to the outer attachment plate 22'. If the door is thick, the outer fixing plate 31 'is reversed, and if the door is thin, the door is moved forward so that the scale and the outer cover of the lock body 7 are engraved on the upper surface of the fixing body 32 of the system. (6) Check the scale (6 ') engraved on the upper surface through the display (6) to adjust.

For example, the scale 6 'engraved on the outer cover 6 has a mark line indicating the thickness of the normalized door (1 3/8 inch on the inside and 1 3/4 inch on the outside). The push button 41 of the operating lever 40 connected to the stop bar 3 for controlling the redirector 1 of the lock body 7 is also adjusted by adjusting the scale engraved on the upper surface of the body 32. It should be protruded or charged accordingly. When the end of the operation lever 40 is pressed, the end of the operation lever 40 is retracted by the posted spring 43. At this time, the push button 41 is moved back and forth to move by an adjusted interval. What is necessary is just to fit in the protrusion 42 formed by bending to both sides of the operation lever 40 in the hole 43 formed in the push button 41. As shown in FIG.

After adjusting the inner and outer fixing plates 31 and 31 'according to the thickness of the door, the outer fixing plate 31' and the saddle 33 are fixed to the outer side plate 22 'and then the inner and outer mounting plates 22 are fixed. , 22 ') can be fixed firmly with a set screw.

Looking at the exact operating relationship of the present invention as described above, in the case of locking and unlocking, the stop bar (3) of the operating lever (40) by pressing the pushbutton 41 as in the prior art locks (2) The end is fitted into the insertion hole formed in the charging hole of the outspindle (not shown) on the outer side of the redirector 1 to stop the operation so as to be in a locked state. It is a state in which the lock state is terminated by rotating or loading the lock lever connected to the mounting plate spindles 12 'attached to the outer lever 13' by the key using a key.

This is because when the levers 13 and 13 'are rotated, the mounting plate spindles 12 and 12' mounted on the mounting plates 22 and 22 'rotate together with the levers 13 and 13' so that the mounting plate spindles 12, 12 ') fitting protrusions 21 formed on the body spindles 10 and 10' formed on both sides of the lock body 7 are interfitted with the body spindles 10 and 10 '. It works by rotating it.

At this time, the branches 26, 26 ′ of the spring anchor plate 27 fixed to the end of the mounting plate spindle 12 charged into the charging hole 23 of the inner mounting plate 22 are formed on the mounting plate 22. When the lever 13 is operated after the lever 25 is rotated to the left and right while pushing the spring 25 in which the bent portion is locked to the locking protrusion 24, the spring 25 is rolled back by the elasticity of the spring 25, and the inner and outer levers 13, 13 '), the branches 26, 26' of the spring set plate 27 fixed to the ends of the attachment plate spindles 12, 12 'are applied to the inner surface of the attachment plates 22, 22' Since the stopper 28 is formed in the locking force is not transmitted to the body spindle (10, 10 ') by rotating the lever (13, 13').

In addition, a plurality of fixing protrusions 30 and 30 'are formed on the inner fixing plate 31 fixed to the front surface of the inner attaching plate 22 to fix the two fixing plates 22 and 22' as fixing screws. When the plurality of fixing protrusions 30 and 30 'formed on the inner fixing plate 31 are fixed to the surface of the door, the levers 13 and 13' are formed on the mounting plates 22 and 22 'even if the levers 13 and 13' are forcibly rotated. It stops with the stopper 28 and is fixed between the attachment plates 22 and 22 'so that the force to the lock body is not transmitted, and the body spindles 10 and 10' and the attachment plate are fixed. Indirect connection is made by dividing the spindle 12, 12 'so that only the minimum rotational force necessary for operation is transmitted by the rotation of the lever 13, 13' and it occurs when the lever 13, 13 'is pulled or pushed. In the case of the horizontal force, the fitting protrusion 21 formed in the mounting plate spindles 12 and 12 'is inserted into the opening 20 formed in the body spindles 10 and 10'. Air, so the fitting projection 21 is not in accordance with the opening 20, so the sliding movement is not transmitted to the force of the locking body 7 and the spindle body 10 and 10 '.

When the body spindles 10 and 10 'are rotated by operating the levers 13 and 13', the fixing plate 32 of the outer fixing plate 31 'and the fixed cassis port 33 is connected to the base plate 5 and the base plate 5, respectively. The body is inserted into the space (S) between the outer cover 6 to support the base plate (5), even if the body spindles (10, 10 ') to operate the redirector 1 while rotating the lock body by the rotational force The twisting phenomenon of (7) can be prevented.

Then, the redirector 1 placed on the base plate 5 is also prevented by the stopper 50 and the guide 53 formed on the base plate 5 to prevent the torsion generated during operation.

This is because when the redirector 1 operates along the side wall 52 of the base plate 5 and the tip portion approaches the side wall 52, the inlet 51 formed by the beneficiation narrowing on the side of the redirector 1 is formed. The stopper 50 enters the stopper 50 formed on the base plate 5, and at about the end of the operation, the stopper 50 is almost finished entering the inlet 51 of the redirector 1. Although not shown) continues to push the redirector 1 to prevent the twisting by the stopper 50, the guide 53 is inserted between the redirector 1 and the side wall 52 of the base plate 5 Therefore, the redirector 1 is to catch the flow up and down during operation.

The present invention as described above operates the lever (13, 13 ') by providing an indirect hook by providing a separate spindle (10, 10'12, 12') on the lock body (7) and the mounting plate (22, 22 ') It eliminates the risk of breakage or damage in the vertical and horizontal forces generated during operation, and of course, it prevents twisting of the lock body (7) and the redirector (1) during operation, and it is attached to the thickness of the door to fix the door lock. Along with the width control between the 22 and 22 ', the push button 41 is easy to control the degree of protrusion is devised many advantages.
