The present invention relates to a door handle structure for an electrical equipment box having a double locking device to double-lock the immersive lock handle device used in the electrical equipment box, etc. The guide surface is formed on the top of the built-in groove into which the handle is immersed and the lock is inserted. The ball is formed in the guide hole and the lower end coupled to the casing is connected to the combination by fixing the bolt to the casing is formed directly to the anti-rotation projections.

 Door locks published in Japanese Unexamined Patent Publication No. 7-52300 for constructing handles for immersed electrical equipment boxes installed in doors of electrical equipment boxes or cabinet document storage boxes, etc., which are used for door locking as a door handle. The locking device is rotatably fitted to the front and rear shaft portion of the fixed case, the base of the handle is connected to the front end of the locking shaft, and the fixed metal plate is fixed to the rear end of the locking shaft. It consists of a shaft part that is reduced in diameter to hold the handle, a spring bearing disc that is fitted to the diameter reduced shaft part to abut the compressed coil spring tip, and a ridge protrusion formed on the back side of the handle base and abuts on the front surface of the spring bearing disc. .

The door lock handle device, a patent registration No. 10-0395361 (August 08, 2003), filed by Takigen Seiko, Ltd. of Japan, installs a spring bearing groove on the back side of the handle base, A spring receiving hole is formed in the face part, and the leaf spring for holding the posture of the handle is pushed in between the spring receiving groove spring receiving hole, and when the handle is immersed in the fixed case, the front end and the base of the leaf spring are located at the base of the handle. On the other hand, when the protruding rotation of the handle is started, the base of the leaf spring is disposed so as to pass over to the front end of the handle. Patent registration No. 10-0441850 (July 16, 2004) of the "rotationally operated door lock handle device" is the root end of the bearing part. And one of the end faces of the opening of the cap member are formed with the positioning projections of the mountain shape, and the positioning grooves are formed on the other side. When the surface because the alignment only fully inserted, the operating handle by the reclining position on the non-regular, receiving no work to damage the edge of the recess in the grip.

The "flat handle device with a lock" published in Japanese Patent Application Laid-Open No. 63-198764 includes a casing fixed to a door; A locking shaft which is rotatably fitted to the shaft portion of one side end of the casing and has a fixed metal plate fixed to the rear end thereof; A handle accommodated in the front recess of the casing and pivoted at the front end of the visual axis; A handle driving spring installed between the visibility shaft and the handle; A latch body that is received at the other end of the casing and is engaged with or released from the catch portion provided with the catch click portion at the handle tip portion; A latch body returning spring housed in the other end of the casing; A lock unit accommodated in the other end of the casing; When the rotor of the lock unit is turned to the unlocked position, it is composed of an operation member which drives the latch body back and forth in a direction in which the latch body and the handle are released.

Utility Model Registration No. 0129706 (August 21, 1998) "Push-button flat handle device with lock" includes a casing fixed to the door; A visibility shaft in the shaft portion of one end of the casing; A handle housed in the front recessed portion of the casing; A handle driving spring for urging the handle to rotate in the protruding direction about the axis; A latch body that engages or releases the engaging click portion against the engaging portion installed in the distal end of the handle; A latch body returning spring for urging the latch body forward in the direction of the handle; A lock unit accommodated in the other end of the casing and provided with an operation unit; A lock unit returning spring accommodated at the other end of the casing; and a groove hole is formed in the latch body, and a cam slope is formed in the inner wall side of the base end of the groove hole. The operating part is provided to protrude so as to fit into the groove hole, and a driving slope slid to the cam slope of the latch body is formed at the front end of the operating portion, and the rear end of the rotor crosses a pair of long sides and a pair of short sides And the short side is set to be equal to or less than the opening width of the groove hole, and when the rotor is in the locked position with respect to the lock unit, the long side is disposed in the direction crossing the groove hole. When the rotor is in the unlocked position, the long side is arranged in the direction aligned with the groove hole.

Utility Model Registration No. 20-0419667 (2006.06.16) is a "sealing door handle lock device" is a lock body that is inserted into the operation chamber of the casing, the key to induce opening and closing according to the operation of the key inside the lock body. It consists of a bundle, a fixing bracket which is inserted into the locking body and fixed to the operation chamber by the fixing means, and a spring that is elastically supported between the operating chamber and the locking body.

Utility Model Registration No. 20-0380929 (2005.03.29) As the fixing member is lifted by the operation of the key holder between the body and the locking device, the handle locked by the locking device is more firm as the inner peripheral surface of the body is brought into close contact with each other. It is an object of the present invention to provide a hermetically sealed door handle lock.

However, when the door handle structure needs to be secured to prevent the door from being opened easily, such as to maintain the airtightness by forming a single locking device configured in the casing so as to be integral with the handle or to restrain the handle, the single door locking device may be used. When there was a deficiency and a complicated locking device failed, it caused a problem in retrieving the door right now, causing a lot of problems such as exposing the inside of the box to security or other dangers.

Therefore, the present invention is intended to provide another locking device to double lock the handle separately from the locking device, and to provide a more perfect fixing and easy to use in constructing the dual key device. .
