Detailed Description

The following description is presented to disclose the invention so as to enable any person skilled in the art to practice the invention. The preferred embodiments in the following description are given by way of example only, and other obvious variations will occur to those skilled in the art.

The lock body structure of the outdoor low-voltage distribution box shown in the attached figures 1-4 comprises an open lock 1 and a built-in lock 2, wherein the built-in lock 2 comprises a lock shell 3 fixed on the inner side of a box door, a bolt 4 sliding in the lock shell 3 along the horizontal direction and a strong magnet 5, the lock shell 3 is fixed on one side away from a hinge of the box door, the strong magnet 5 is fixed on one side away from the hinge of the box door by the bolt 4, the bolt 4 and the strong magnet 5 can be completely contained in the lock shell 3, the lock shell 3 is made of nonmagnetic metal materials, and the bolt 4 is arranged on the inner side of a flange of a box body.

Outdoor low voltage distribution box chooses for use current commonly used block terminal, as long as can cooperate the realization the utility model discloses the block terminal of purpose and effect, perhaps with the utility model discloses other parts are conflicting, all can choose for use, in this preferred embodiment, the block terminal chooses for use the cooperation of singly opening the door structure to can realize bolt 4 and box.

In this embodiment, the mortise lock 1 is well known to those skilled in the art, and will not be described in detail herein.

During operation, the bolt 4 is firstly accommodated in the lock shell 3, then the door of the distribution box is closed with the box body, at the moment, an external strong magnet opposite magnetic pole is used for attracting (opposite pole attracting) one side of the box body (namely one side of the strong magnet 5), the strong magnet 5 is adsorbed, the strong magnet 5 is enabled to move towards the left side of the lock shell 3 along the horizontal direction (such as the left side of a figure 4) and is inserted into a pin hole 8 formed in the box body, and at the moment, under the matching of the bolt 4 and the pin hole 8, the locking hidden type of the door and the box body of the distribution box can be realized; when the door needs to be opened, the strong magnet is taken out and is repelled with the outer side of the strong magnet 5 by the same magnetic pole (the same level), so that the bolt 4 is accommodated in the lock shell 3 to complete the unlocking action, and finally the door can be opened.

In this embodiment, the screw 6 is installed on the lock case 3, the hexagonal long nut 7 is connected to one end of the screw 6 in a threaded manner, the screw 6 is set perpendicular to the bolt 4, and the ends of the screw 6 and the hexagonal long nut 7 can abut against the inside flanging groove of the box door. Two built-in locks 2 are fixed on the screw 6. The magnetic poles of one strong magnet 5 of the two built-in locks 2 are of N level, and the magnetic poles of the other strong magnet 5 are of S level.

The utility model discloses a theory of operation:

referring to the attached drawings 1-4 of the specification, in operation, firstly, the bolt 4 is accommodated in the lock shell 3, then the door of the distribution box is closed with the box body, at this time, a strong magnet is attracted by a strong magnet opposite magnetic pole (opposite pole attraction) at one side of the box body (namely, one side of the strong magnet 5), the strong magnet 5 is adsorbed, the strong magnet 5 is enabled to move towards the left side of the lock shell 3 along the horizontal direction (such as the left side of fig. 4) and is inserted into a pin hole 8 formed in the box body, and at this time, under the matching of the bolt 4 and the pin hole 8, the hidden locking of the door and the box body of the distribution box can be realized; when the door needs to be opened, the strong magnet is taken out and has the same magnetic pole (same-level repulsion) with the outer side of the strong magnet 5, so that the bolt 4 is accommodated into the lock shell 3 to complete the unlocking action, and finally the door can be opened;

in the embodiment, the screw 6 is installed on the lock shell 3, the lower end of the screw 6 is in threaded connection with the hexagonal long nut 7, the screw 6 is perpendicular to the bolt 4, the upper end of the screw 6 and the lower end of the hexagonal long nut 7 are abutted against the inner side edge groove of the box door, the screw 6 can be fixed on the inner side of the box door by rotating the hexagonal long nut 7, secondary hole opening is not needed for fixing, the box door can be installed and fixed according to different sizes, and the practicability is high;

in the embodiment, two built-in locks 2 are fixed on the screw 6, the magnetic poles of the powerful magnet 5 of the built-in lock 2 at the upper end are N-level, the magnetic poles of the powerful magnet 5 of the built-in lock 2 at the lower end are S-level, and the two magnetic poles are different, so that the difficulty in unlocking is increased;

to sum up: through the combination of the open lock 1 and the built-in lock 2, the built-in lock 2 is hidden in the distribution box and is not easy to be found, and the protection effect on the box body is increased.
