Description

Prevent safe block terminal of mistake division

Technical Field

The utility model relates to a block terminal, specific theory has related to a prevent safe block terminal of open by mistake.

Background

The distribution box is one of the most common devices in the power system, and for the staff of the power system, there is a set of strict operation rules to avoid various accidents.

However, most of the distribution boxes are installed outdoors, and there is no prevention and control means around the distribution boxes, which results in that the safety of the distribution boxes is greatly reduced, and especially children or other useful people can open the doors of the distribution boxes through violent means.

At present, the block terminal does not have the means of preventing the mistake and open, and the lock that uses is also ordinary world lock mostly, under this prerequisite, though there is some products to design the structure of double-deck door, this kind of structure also inevitably leads to the whole volume increase of equipment, and second door and first door do not have the particularity, still can open through the same means.

And a part of distribution boxes adopt an intelligent protection means, various electronic equipment and remote equipment are added, but the cost is greatly increased, the equipment is suitable for important nodes with high safety level requirements, and a common distribution box cannot be applied.

In order to solve the above problems, people are always seeking an ideal technical solution.

Disclosure of Invention

Detailed Description

The technical solution of the present invention will be described in further detail through the following embodiments.

As shown in fig. 1, the safety distribution box capable of preventing false opening comprises a box body 1 and a box door 2, wherein one side of the box door 2 is installed on the box body 1 through a hinge 10, and the other side of the box door 2 is locked with the box body 1 through a top-bottom lock 3, so that a main body structure identical to that of a conventional distribution box is formed.

As shown in fig. 2-6, a vertical gap 4 is formed on the box body 1 corresponding to the hinge side of the box door 2, a box door flange 5 forming a right angle with the box door 2 is fixedly arranged on the hinge side of the box door 2 corresponding to the gap 4, and the box door flange 5 can pass through the gap 4 along with the rotation of the box door 2.

In fig. 6, the hinge 10 is installed at the lower part, the upper end of the box door 2 is hinged with the box body 1 through a pin shaft to play a stabilizing role, and the dotted line in the figure indicates the rotation center line of the box door.

The long-strip-shaped protective lock 6 is arranged at the notch 4, the lower end of the protective lock 6 is arranged at the notch 4 through a hinge 10, the upper end of the protective lock 6 is locked with the box body 1 through a lock body 7, and the side edge 6-1 of the protective lock 6 is used for limiting the box door flange 5.

Principle of the protective lock 6 limiting the door flange 5:

as shown in fig. 2, when the protection lock 6 is closed, the side 6-1 of the protection lock 6 is attached to the door flange 5, and the door flange 5 is restricted by the protection lock 6 and cannot move, and at this time, even if the door is opened, the door cannot move and be opened because the door flange 5 is restricted.

As shown in fig. 4, in the state that the protection lock 6 is opened, the protection lock 6 is wholly turned outwards to open the notch 4, the box door flange 5 is not limited by the protection lock 6 and can rotate, and at the moment, the heaven and earth lock on the box door 2 is opened, and the box door can rotate freely.

The purpose is as follows: the area of chamber door is great, can utilize multiple instrument to open, for example crowbar, brute force etc. but, after adding the protection lock, even if will prize, because the restriction of chamber door flange 5, chamber door 2 still can't be opened, more importantly, protection lock 6 is rectangular form, and the volume is less, but the place of application of force is less, and the possibility of artificial destruction is very low, and the degree of difficulty is very high, improves the security of block terminal.

Further, in order to guarantee the security of block terminal, avoid operating personnel to forget when closing the block terminal and close protection lock 6, still be provided with safety bar 7, the one end of safety bar 7 corresponds heaven and earth lock 3 sets up keyhole 7-1, and the other end of safety bar 7 extends to protection lock 6 and is connected through one section flexible stay wire 9 with safety bar 7, be provided with the spout that supports safety bar 7 on the box 1, spring 8 is passed through to the one end of safety bar 7 and is connected with box 1.

The working principle of the safety strip 7 is as follows:

as shown in fig. 3, when the protection lock 6 is closed, the safety bar 7 moves under the action of the restoring tension of the spring 8, the keyhole 7-1 of the safety bar 7 faces the lock bar of the top-bottom lock 3, and the top-bottom lock 3 of the box door 2 can be normally locked.

As shown in fig. 5, when the protection lock 6 is in an open state, the protection lock 6 pulls the safety bar 7 to move through the pull wire, the spring 8 is stretched, the keyhole 7-1 of the safety bar 7 is dislocated with the lock bar of the top and bottom lock 3, and the top and bottom lock 3 of the box door 2 cannot be locked.

The use process comprises the following steps:

when the distribution box needs to be opened, the protective lock 6 on the side part is firstly opened, the box is turned outwards for a certain angle, the gap is opened, and then the heaven-earth lock on the box door 2 is opened, so that the distribution box can be opened; at this time, the safety bar 7 moves a small distance under the pressure of the spring due to the loss of the support of the protective lock 6 and the lock rod limitation of the top and bottom lock 3;

when the distribution box is closed after use, the protective lock 6 is pushed up for a certain distance, the spring 8 drives the safety bar 7 to reset, the keyhole 7-1 on the safety bar 7 is opposite to the lock rod of the top-bottom lock 3, the closing of the box door 2 is completed, and then the protective lock 6 is closed.

Because the in-process of closing the door, need continuously pay close attention to the state of protection lock 6, just can not miss the closing of protection lock 6 yet, improve the security.

Finally, it should be noted that the above embodiments are only used for illustrating the technical solutions of the present invention and not for limiting the same; although the present invention has been described in detail with reference to preferred embodiments, it should be understood by those skilled in the art that: the invention can be modified or equivalent substituted for some technical features; without departing from the spirit of the present invention, it should be understood that the scope of the claims is intended to cover all such modifications and variations.
