Abstract

The utility model belongs to the technical field of substations and discloses a door lock of a box-type substation, which includes a lock core, wherein a connecting sheet is in rotational connection with the lock core; and connecting rods are in rotational connection with the two ends of the connecting sheet. When the lock core is rotated, the connecting sheet is rotated along with the lock core, so as to drive the connecting rods hinged on the connecting sheet to move, namely, the upper connecting rod moves upwards and is higher than the inner edge of the top of the door frame, and the lower connecting rod moves downwards and is lower than the inner edge of the bottom of the door frame, as a result, the upper and the lower ends of the door are limited at the same time, the door is prevented from shaking, and the risk that the door is pried is greatly reduced.

Description

A door lock for a box-type substation

technical field

The utility model belongs to the technical field of substations, in particular to a door lock of a box-type substation.

Background technique

The box-type substation is a factory prefabricated indoor and outdoor compact power distribution equipment that integrates high-voltage switchgear, distribution transformers and low-voltage power distribution devices according to a certain wiring scheme. Power distribution and other functions are organically combined and installed in a moisture-proof, rust-proof, dust-proof, rodent-proof, fire-proof, anti-theft, heat-insulating, fully enclosed, movable steel structure box, mechanical and electrical integration, fully enclosed operation, It is especially suitable for the construction and transformation of urban network, and it is a brand-new substation emerging after the civil substation. The door lock of the box-type substation is suitable for mines, factories, enterprises, oil and gas fields and wind power stations. It replaces the original civil engineering power distribution room and power distribution station, and becomes a new type of complete power transformation and distribution device.

The side wall of the box-type substation is generally equipped with a door. One end of the left and right ends of the door is hinged on the side wall, and the other end is provided with a door lock. Since the volume of the box-type substation is generally relatively large, the length and width of the door are different. It is very large, and the general door lock can only fix one point on the door, and other positions on the door cannot be well positioned, resulting in easy shaking of the upper and lower ends of the door after the door is locked. Even some criminals can enter the inside of the substation by prying open one of the upper and lower ends of the door.

A method that is easy to think of is to also set door locks at the upper and lower ends of the door, but when opening the door in this way, the door locks need to be opened one by one, which greatly increases the workload.

Contents of the invention

The utility model aims at the deficiencies in the prior art, and provides a door lock of a box-type substation, which can effectively prevent the upper and lower ends of the door from shaking, and greatly reduce the risk of the door being pried.

In order to solve the above technical problems, the utility model is solved by the following technical solutions: a door lock of a box-type substation, including a lock cylinder, a connecting piece is rotatably connected to the lock cylinder, and the two ends of the connecting piece are rotatably connected There are connecting rods. When the lock cylinder is turned, the connecting piece rotates with it, driving the connecting rod hinged on the connecting piece to move, so that the upper connecting rod moves upwards higher than the top inner edge of the door frame, and the lower connecting rod moves downwards lower than the inner edge of the bottom door frame , so that the upper and lower ends of the door are also limited at the same time, preventing the door from shaking and greatly reducing the risk of the door being pried.

In the above technical solution, preferably, a through hole is opened in the center of the connecting piece, and the lock cylinder is hinged to the through hole through a nut.

In the above technical solution, preferably, through holes are opened at both ends of the connecting piece, and the lower end of the connecting rod is a flat hinged portion, and the pin is fixed on the connecting piece after passing through the hinged portion. the

The beneficial effect of the utility model is that: the upper and lower ends of the door are fixed at the same time, effectively preventing the upper and lower ends of the door from shaking, and greatly reducing the risk of the door being pried.

Detailed ways

The utility model will be further described in detail below in conjunction with the accompanying drawings and specific embodiments: Referring to Figures 1 to 2, a door lock for a box-type substation includes a lock cylinder 3 and a connecting piece 2, and the middle of the lock cylinder 3 and the connecting piece 2 The position is fixed. Both ends of the connecting piece 2 are provided with through holes 21, 22, and the lower ends of the connecting rods 11, 12 are flat hinged parts 4, and the latch 5 passes through the hinged part 4 and is fixed on the connecting piece 2.

Referring to Figure 3 and Figure 4, when the door lock of the box-type substation is closed, the end of the connecting rod 11 is higher than the height of the door, the end of the connecting rod 12 is lower than the lower end of the door, and the connecting rods 11, 12 Closely attached to the inside of the cabinet body, the door has a better fixing effect, and a guide block 6 is also arranged on the back of the door, and connecting rods 11, 12 pass in the holes of the guide block 6 . When the cabinet door is opened, the lock cylinder rotates, driving the connecting piece 2 to move the connecting rod 11 downward along the guide block 6, and the connecting rod 12 moves upward along the guide block, so that the end of the connecting rod 11 is lower than the upper end surface of the door. , the end of connecting rod 12 is higher than the lower end surface of the door surface, and the fixing effect of connecting rod 11,12 on the cabinet door disappears.
