Abstract

Since the operation handle cannot be laid down when the operation handle is not in the front facing position in the accommodation recess, the lock handle device for the pull-out rotary operation door is provided without damaging the edge of the accommodation recess as part of the operation handle.

The cap member 12, which is integrally rotated with the lock shaft 11 of the operation handle 10, is fitted to the bearing portion 3 that forms part of the casing 1. A positioning projection 5 is provided on either of the bearing portion 3 and the end face of the cap member 12, and a positioning groove 14 is provided on the other side. When the part 2 is in the front facing position, the operation handle 10 is laid down by being fully fitted.

Description

LOCK HANDLE DEVICE FOR PULLOUT ROTARY OPERATION TYPE DOOR}

The present invention relates to a lock handle device for a drawer rotary door used in a switchboard accommodating box or the like.

In the conventional pull-out door lock handle device, even if the fixed metal plate is returned to the normal locking position and the operation handle is not the front facing position exactly facing the front side of the housing recess of the casing, the operation handle is moved in the pressing direction. It is a structure that can be made.

For this reason, in such a non-facing position, if an attempt is made to press the operation handle excessively into the casing, the operation handle may damage the edge portion of the housing recess of the casing, and the plating or the like may be destroyed, causing corrosion to proceed from the portion. It was supposed to be.

An object of the present invention is to provide a lock handle device for a draw-out rotary operation door which makes it impossible to press the operation handle unless the operation handle is in a position facing the receiving recess of the casing.

1 is a longitudinal right side view of a pull-out rotation type door lock handle device according to an embodiment of the present invention, wherein the operation handle 10 is laid face to face with the receiving recess 2 of the casing 1;

2 is a longitudinal side view when the operation handle is pulled out of the casing, and

3 is a partially enlarged plan view seen from the arrow of 3-3 in FIG.

3: bearing part 4: end face

5: positioning protrusion 6: spring

10: operation handle 11: lock axis

12 cap member 13 opening end surface

14: positioning home 15: donation

18: second side

In order to achieve the above object, in the lock handle device of the present invention, when the operation handle 10 is pulled out from the accommodation recess 2 of the casing 1, the lock shaft 11 connected to the operation handle 10 is spring-loaded. It has a structure which slides backward by the pressurization of (6).

A cap fixedly rotatably fixed to the lock shaft 11 to the bearing portion 3 constituting a part of the casing 2 in which the lock shaft 11 is rotatably fitted and movable in the front-rear direction. The member 12 is rotatably fitted to the outer side of the bearing part 3. A positioning projection 5 is formed on one of the root end 4 of the bearing portion 3 and the opening end surface 13 of the cap member 12, and a positioning groove 14 is formed on the other. have. These positioning projections 5 and the grooves 14 are arranged so as to be fully fitted only when the operation handle 10 is faced to the receiving recess 2.

In the lock handle apparatus of this invention comprised as mentioned above, when the operation handle 10 is pulled out, the lock shaft 11 will move back to the axial direction by the pressurization of the spring 6, and at the same time the cap The member 12 also moves together, and the base end face 4 of the bearing portion 3 and the opening end face 13 of the cap member 12 are separated from the approaching or abutting state, and the positioning projection 5 is positioned. The engagement of the grooves 14 is completely separated.

In this way, the operation handle 10 is rotated about the lock shaft 11, the fastener which is integrally connected with the lock shaft 11 is rotated, and the engagement with the fixed frame body is released, and then the casing 1 Open the door to which is fixed.

When correcting the door, after closing the door and returning the operation handle 10 to the front facing position with the receiving recess 2 of the casing 1, the positioning projection 5 and the positioning groove 14 The phases coincide. When the operation handle 10 is laid down in this state, these positioning projections 5 and the positioning grooves 14 mesh with each other, and the operation handle 10 completely coincides with the position of the receiving recess 2 inwardly. Return to.

When the operation handle 10 is not returned to the position facing the receiving recessed part 2, since the positioning projection 5 hits the surface of the root end 4 of the bearing part 3, the operation Do not lay the handle 10 down.

In the embodiment shown in FIG. 3, since the positioning projection 5 makes the inclined surface of the mountain shape and the both wall surfaces of the base 5a parallel, the operation handle 10 is the accommodation recess portion 2. Even if the phase is not completely coincident with the phase, the operation handle 10 is guided to the normal phase at the roughly inclined surface of the positioning projection 5, and the parallel portion 5a is positioned at the end. Fully fitted to (14), the operation handle 10 is completely lying in phase with the recessed concave portion 2 in contact with the edge of the concave convex portion 2 without causing contact.

In addition, in embodiment shown, the attachment bolt 20 fixed to a door etc. is equipped in the back surface side of the casing 1.

The base 15 of the operation handle 10 is pivotally attached to the pin 16 perpendicular to the lock shaft 11, and the first surface 17 and the second surface 18 around the pin 16. Is installed. When the operation handle 10 is lying down, the first surface 17 abuts on the left half 1a, and when the operation handle 10 is pulled out, the second surface 18 is placed on the left half 1a. Abuts. The first surface 17 is formed at a position far larger than the pin 16 than the second surface 18, and the compression spring 6 interposed inside the bearing portion 3 and the cap member 12. Silver presses the left half 1a stably to either one of the 1st surface 17 and the 2nd surface 18, and makes contact. When the operation handle 10 is pulled out, the lock shaft 11 connected to the operation handle 10 is equal to the difference between the distance between the first surface 17 and the second surface 18 with respect to the pin 16. It slides backward by the press of the spring 6.

Further, a cylinder lock 19 is provided on the inner side near the tip of the operation handle 10, and the operation handle 10 can be locked to the casing 1 by use of a key not shown.

In the drawer rotation operation type door lock handle device of the present invention configured as described above, the position of the mountain shape is positioned on either one of the base end 4 of the bearing portion 3 and the opening end surface 13 of the cap member 12. The projection 5 is formed, and the positioning groove 14 is formed on the other side, and the positioning ridge protrusion 5 and the groove 14 have the operation handle 10 facing the receiving recess portion 2 in front. Since only a perfect fit is made, the operation handle 10 is laid down at an irregular position so that the edge of the accommodation recess 2 is not damaged by the operation handle.

In addition, in the embodiment, since the positioning projection 5 is the shape described above, if the projection 5 and the groove 14 substantially coincide with each other, the operation handle 10 and the accommodation recess are laid down by lying down the operation handle 10. The part 2 can be automatically matched with a front-to-face phase.
