Description

Door lock mechanism for medium voltage complete sets of equipment

technical field

The utility model relates to a switch door lock mechanism of electric power equipment, in particular disclosing a door lock mechanism of a medium-voltage complete set of equipment.

Background technique

Most of the cabinet doors of medium-voltage complete sets of equipment are closed by longitudinal bolting, which has vibration and jamming; there are also horizontal bolts, but such mechanisms are complicated in structure and cumbersome to operate.

Utility model content

The purpose of the invention of this utility model is to provide a door lock mechanism for medium voltage complete sets of equipment with simple structure, flexible operation and reliable strength in order to solve the above problems.

The technical scheme that the utility model adopts is such:

Medium-voltage complete equipment door lock mechanism,

Including closing lever, connecting plate and connecting rod,

There are at least two door-closing rods, which are arranged in parallel in the transverse direction, one end of which is inserted into the sleeve arranged on the side of the door hinge, and the other end is inserted into the lock tripper through the guide support in the door;

The connecting plate is used for connecting the door closing lever and the connecting rod;

The connecting rod is arranged parallel to the door closing rod, one end of which is fixed to the connecting plate, and the other end is connected to the door lock;

Turning the door lock drives the connecting rod to move left and right, the connecting rod drives the connecting plate to move synchronously, and the connecting plate drives the door closing rod to enter and exit the lock tripper to realize the door opening and closing action.

Further, the door inner guide support is welded and fixed in the door, which is used to erect the door closing lever; the end of the door closing lever will not be separated from the door inner guide support when moving.

Further, between the door closing lever and the connecting plate, between the connecting rod and the connecting plate are positioned and fixed by positioning retaining rings.

In summary, due to the adoption of the above technical solution, the beneficial effects of the utility model are:

The utility model realizes the opening and closing of the cabinet door by means of horizontal bolting, and has the advantages of simple structure, flexible operation and reliable strength.

detailed description

Below in conjunction with accompanying drawing and embodiment the utility model is described in further detail.

As shown in Figure 1-4, the door lock mechanism of the medium voltage complete set of equipment,

Including door closing lever 5, connecting plate 3 and connecting rod 7,

Described closing bar 5 has three, is distributed in the upper, middle, lower part of cabinet door 9, and horizontal parallel is arranged, and its one end inserts and is arranged on the sleeve 2 (sleeve 2) that is arranged on door hinge 1 setting side (cabinet door 9 and cabinet body connection side) The cylinder 2 is long enough to ensure that the movement of the door closing rod 5 will not break away from the sleeve 2), and the other end passes through the door inner guide support 10 and is inserted into the lock 11; the door inner guide support 10 is welded and fixed in the door , which is used to set up the door-closing lever 5; its end (inserted into the end of the latch 11) of the door-closing lever 5 will not break away from the guide support 10 in the door.

The connecting plate 3 is used to connect the door closing lever 5 and the connecting rod 7, and the connection between it and the closing lever 5 and the connecting rod 7 is positioned and fixed by the positioning retaining rings 4, 6, and the connecting plate 3 plays a transmission role;

The connecting rod 7 is arranged parallel to the door closing lever 5, one end of which is fixed to the connecting plate 3, and the other end is connected to the door lock 8;

Rotating door lock 8 drives connecting rod 7 to move left and right, and connecting rod 7 drives connecting plate 3 to move synchronously, and connecting plate 3 drives door-closing lever 5 to enter and exit lock tripper 11, realizes opening and closing action.

The above descriptions are only preferred embodiments of the present utility model, and are not intended to limit the present utility model. Any modifications, equivalent replacements and improvements made within the spirit and principles of the present utility model shall be included in this utility model. within the scope of protection of utility models.
