Description

[Detailed Description of the Invention] The present invention relates to an improvement of a locking device for distribution boxes.

As a locking device for distribution boxes, a hook receiver is provided on the edge of the box, and a vertically long window hole is provided on one side of the door plate that is closed to the box. It is widely used that a handle with a hook is slidably attached to the front surface of the door to cover the long window hole and engage with and disengage from the hook holder. On the other hand, if the door is closed with the handle or handle lowered, there is a risk that the hook will collide with the hook holder and be damaged, and the handle may be damaged by vibration etc. There are various drawbacks, such as the generation of noise when they approach and separate.

The present invention was completed with the aim of creating a locking device for distribution boxes that does not have the above-mentioned drawbacks. At the same time, a long window hole 5 is provided at a position corresponding to the hook holder 3 of the door plate 4 that is attached to the box body 1, and a long window hole 5 is provided on the front side of the door plate 4, covering the long window hole 5. In a locking device for a distribution box or the like, in which a handle 7 with a hook 6 that engages and disengages from a receiver 3 is slidably attached, guide pins 8, 8 are protruded from the back surface of the handle 7, and a hook 6 is provided in the center. The lock member 9 is fitted onto the back surface of the handle 7 under the guidance of the guide holes 10, 10 provided therein and the guide pins 8, 8, and the lock member 9 is pushed toward the handle 7 to lock the lock member. Springs 11, 11 are provided to press the edge portions 9', 9' on both sides of the door plate 4 into pressure contact with the back surface of the edge portion of the long window hole 5 of the door plate 4, and each spring 11 is screwed into the tip of the guide pin 8. Head 1 of screw 12
It is characterized in that it is surrounded by the guide pin 8 in a compressed state between the lock member 2' and the periphery of the guide hole on the back surface of the lock member 9. In addition, 1 in the figure
Reference numerals 3 and 13 designate claw pieces that protrude from both sides of the middle of the inverted box-shaped handle 7 as needed to temporarily hold the handle 7 in the long window hole 5;
13, in order to ensure that the tips of the claw pieces 13, 13 are inserted into the long window hole 5 when the handle 7 is attached to the door plate 4, the long window hole 5 is
A notch 15 provided on the side edge of the handle 7 is a chamber defined as necessary in the handle 7 in the shape of an inverted box, into which a locking member is inserted.

With this structure, equipment is mounted inside the box body 1 to serve as a distribution board, and when the door is opened, it is slidably mounted on the front surface of the door plate 4, covering the long window hole 5. When the handle 7 is slid upward, the hook 6 on the back side of the handle 7 is disengaged from the lip frame 2 of the box body 1, and the door can be opened easily. When the door is closed, the handle 7 is slid downward and the hook 6 is engaged with the hook receiver 3 to obtain the locked state, which is similar to the locking device in conventional distribution boxes of this kind. The hook 6 of the present invention is guided by guide pins 8, 8 protruding from the back surface of the handle 7 through guide holes 10, 10, and is normally guided by the edge portions 9', 9' on both sides thereof.
Since the lock member 9' is directed toward the back side of the edge of the long window hole 5 of the door plate 4 and is protruded from the center of the lock member 9 which is pressed under the force of springs 11, 11, the handle can be operated properly. Not only is it easy to secure, but also the door plate 4 when locked.
is pulled toward the box body 1 side by the springs 11, 11, so there is almost no rattling of the door plate 4, and even if it receives vibration when the door is open,
Since the door plate 4, the lock member 9, and the handle 7 are kept in pressure contact by the springs 11, 11, there is no risk of them automatically sliding downward, so it is possible to confirm that they are sliding downward. There is no risk of damage to the hook 6 or the hook receiver 3 that would occur if the door is closed without realizing it, and there is an advantage that it can be used for a long time. Further, the spring 11 is compressed between the head 12' of the screw 12 screwed into the tip of each guide pin 8 and the periphery of the guide hole on the back surface of the locking member 9.
Since the mounting structure is surrounded by a wall, it is easy to assemble and has excellent stability. Furthermore, since the engagement and disengagement between the hook 6 and the hook holder 3 can be detected by hand when operating the handle, there are various advantages such as reliable opening/closing operations and no need to stop operating the handle in a half-open state.

Therefore, the present invention eliminates the disadvantages of the conventional locking device for this type of distribution box, and has the advantage of being simple in structure and can be provided at low cost, and has extremely great practical value. .
