Description

  TECHNICAL FIELD The present invention relates to a locking structure for a door body of an electrical equipment storage box that houses various electrical devices in a box body having an opening on the front surface and covers the opening with a door body that can be opened and closed by a rotating operation. Is.

Conventionally, when the handle of the door of the electric equipment storage box is stationary, the tongue protrudes laterally. When closing the door body, rotate the handle and move the tongue up or down so that it does not hit the box body of the electrical equipment storage box. Further, with the door closed, the handle is returned to the original position and the tongue is hooked on the box body to lock the door to the box body.

  However, according to the above-described conventional technique, if the handle is not operated, the tongue does not operate and the door body is caught by the box body, so it cannot be closed and it takes time to open and close the door body. The body is often left open, in which case rainwater or foreign objects may enter, workers may accidentally touch dangerous places, or the door may be deformed or damaged by strong winds. It was.

  Accordingly, the present invention has an object to provide a locking structure for a door body of an electric equipment storage box that can be easily closed with a simple structure, and the structure has a handle on the front surface of the door body. A velo is attached to the back of the handle by a velo presser linked to the operation of the handle. The velo is moved by sliding movement, and the velo is biased by a spring. At the same time, the handle is returned to its original position, and when closing the door body, the tongue is locked to the box body without operating the handle by hand, and the door body can be temporarily fixed. .

  In addition, the slide structure of the Vero has a substantially elliptical shape for the Velo presser to which the Vero is attached, and the Velo has a substantially elliptical cutout. The tongue is fixed when facing the diameter, and the tongue is slidable within the range of the notch when the major diameter of the tongue presser faces the major diameter of the notch.

  In the locking structure of the door of the electrical equipment storage box according to the present invention, a handle is provided on the front surface of the door, and a tongue is attached to the rear surface of the handle by a tongue press that is linked to the operation of the handle. It operates by sliding movement, and the tongue is biased by a spring. When the hand is released from the handle, the handle returns to the original position together with the tongue, and when the door is closed, the handle is held by hand. Since the tongue can be locked to the box body without stopping, and the door body can be temporarily fixed, the blade slides when it hits the box body without operating the handle, and locks to the box body. As a result, it is safe to leave the door body open and to avoid accidental touching the internal device and cause an electric shock. In addition, since the door body is not left open, it is possible to prevent rainwater from entering, particularly when used outdoors, and the internal devices are not adversely affected. Also, if the door is not closed, it will not be deformed or damaged by being hit by a strong wind.

  In addition, the slide structure of the Vero has a substantially elliptical shape for the Velo presser to which the Vero is attached, and the Velo has a substantially elliptical cutout. The velo is fixed when facing the diameter, and the velo can be slid within the notch when the major diameter of the bevel presser faces the major diameter of the notch. When it hits the box body, it slides and locks to the box body, so it is less likely to leave the door open, and it may accidentally touch internal equipment and cause an electric shock. It is safe to lose. In addition, since the door body is not left open, it is possible to prevent rainwater from entering, particularly when used outdoors, and the internal devices are not adversely affected. Also, if the door is not closed, it will not be deformed or damaged by being hit by a strong wind.

  A box for storing electrical equipment that is often used outdoors such as temporary boards, and closes the door without having to operate the handle to lock the door to the box body. The purpose of being able to do this was realized by sliding the tongue of the handle.

  A door body locking structure of an electrical equipment storage box according to the present invention will be described with reference to the accompanying drawings of FIGS.

  The electric device storage box 1 for storing various electric devices has the electric device placed on the box body 2 and the front opening is covered with the door 3. The door body 3 is hinged to the box body 2 and can be opened and closed by a rotating operation. A handle 4 is provided on the surface of the door body 3, and a tongue 5 is attached to the back surface of the handle 4. When the door 3 is closed, the tongue 5 is temporarily fixed by being locked to the box body 2.

  When the door 3 is in a closed state, the tongue 5 protrudes outward and is locked to the box body 2, and the door 3 is temporarily fixed to the box body 2. When the door body 3 is opened, the handle 4 is rotated to move the tongue 5 inward, and the locking to the box body 2 is released. A spring 8 is attached to the bellows 5 to urge the bellows 5, and when the hand is released from the handle 4, the bellows 5 returns to the original outer position.

  When closing the door 3, the tongue 5 hits the box body 2 and moves inward without operating the handle 4. Further, the door 3 is closed, and when the door 3 completely closes the opening of the box body 2, there is no interference of the tongue 5 with the box body 2, and the tongue 5 moves outward by the spring 8. Enter the inside of the main body 2 and temporarily fix the door 3 to the box main body 2.

  The tongue 5 is attached to the door body 3 by pressing it with a substantially elliptical tongue holder 6, and the tongue 5 is also provided with a substantially elliptical cutout 7. The bellows presser 6 rotates in conjunction with the turning operation of the handle 4, and when the elliptical shape of the bellows presser 6 is aligned with the notch 7 provided on the bellows 5, the bellows 5 is notched 7 on the bellows 5. Move the slide as much as possible. When the major axis of the tongue holder 6 is opposed to the minor axis of the notch 7 of the tongue 5, the tongue 5 is fixed. A spring 8 is attached to the tongue 5 and biased so that it returns to its original position after the operation.

  When closing the door 3, the tongue 5 hits the box body 2 and moves inward without operating the handle 4. Further, when the door 3 is closed and the door 3 is aligned with the box body 2, the interference of the tongue 5 with the box body 2 is eliminated, and the tongue 5 is moved outward by the spring 8 provided on the tongue 5. Enter the inside of the main body 2 and temporarily fix the door 3 to the box main body 2.

  Finally, by rotating the handle 4, the tongue presser 6 is interlocked and fitted into the notch 7 provided in the tongue 5, the tongue 5 is fixed, and the door body 3 is locked to the box body 2.

  The door locking structure of the electrical equipment storage box according to the present invention is not limited to the above shape, and the shape of the tongue can be changed as appropriate without departing from the spirit of the present invention.

  Further, the attachment position of the spring for biasing the tongue can be changed as appropriate without departing from the spirit of the present invention.

  The door of the electrical equipment storage box can be temporarily fixed by locking the tongue to the box body, but the tongue moves even without operating the handle, and the door is engaged with the box body. Since it can be stopped, it can be applied to a temporary board that is often used outdoors where the handling tends to be complicated.
