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 kind of door lock of box-type substation
Technical field
The utility model belongs to transformer station's technical field, especially relates to a kind of door lock of box-type substation.
Background technology
Box-type substation is a kind of with high voltage switchgear equipment, distribution transformer and low-voltage distribution equipment; Line up indoor, the outdoor close-coupled controller switching equipment of prefabrication of one by certain connection plan; Being about to functions such as high powered, transformer step-down, low-voltage distribution organically combines; Be installed in a protection against the tide, antirust, dustproof, protection against rodents, fire prevention, antitheft, heat insulation, totally-enclosed, movably in the steel work casing, electromechanical integration, totally-enclosed operation; Being specially adapted to city net construction and upgrading, is a kind of brand-new transformer station that after civil engineering transformer station, emerges.The door lock of box-type substation is applicable to mine, factory and enterprise, oil gas field and wind power station, and it has substituted original civil engineering power distribution room, and power substation becomes novel complete change power distribution equipment.
Operated by rotary motion has door on the sidewall of box-type substation, and right ends one end of door is hinged on the sidewall, and the other end is provided with door lock; Because the volume of box-type substation is generally all bigger; So the length and the width of door are all very big, and the point of general door lock on all can only fixed gate, other position can not well be located on the door; After causing on the door lock, the two ends up and down of door are easy to generate rocks.Even some lawless persons can enter into transformer station inside through the end in the two ends up and down of prying open door.
A method that is easy to expect is at the two ends up and down of door door lock to be set also, and the needs when still this mode is opened the door are opened door lock one by one, have increased workload greatly.
Summary of the invention
The utility model provides a kind of door lock of box-type substation to deficiency of the prior art, can prevent effectively that the two ends up and down of door from rocking, and has significantly reduced the risk that door is prized.
For solving the problems of the technologies described above, the utility model is able to solve through following technical proposals: a kind of door lock of box-type substation, comprise lock core, and be rotatably connected to brace on the said lock core, the two ends of said brace are rotatably connected to connecting rod.When rotational lock core; Brace and then rotates together, drives to be hinged on the link motion on the brace, and the connecting rod above making up moves and exceeds doorframe top inward flange; The connecting rod of below down moves and is lower than doorframe bottom inward flange; The two ends up and down of door also are defined simultaneously like this, prevent to rock, and have significantly reduced the risk that door is prized.
In the technique scheme, preferred, the center of said brace offers through hole, and said lock core is articulated on the through hole through nut.
In the technique scheme, preferred, the two ends of said brace offer through hole, and the lower end of said connecting rod is the articulated section of tabular, and latch is fixed on the brace after passing the articulated section.
The beneficial effect of the utility model is: the two ends up and down of door are fixed simultaneously, have prevented that effectively the two ends up and down of door from rocking, and have significantly reduced the risk that door is prized.
Description of drawings
Fig. 1 is the survey view of the utility model.
Fig. 2 is the rear elevation of the utility model.
Fig. 3 is contained in the sketch map of door door closure state of last time for this use is novel.
Fig. 4 is contained in the sketch map of door door open mode of last time for this use is novel.
The specific embodiment
Below in conjunction with the accompanying drawing and the specific embodiment the utility model is described in further detail: referring to Fig. 1 ~ Fig. 2, a kind of door lock of box-type substation comprises lock core 3 and brace 2, and lock core 3 fixes with the centre position of brace 2.The two ends of brace 2 offer through hole 21,22, and the lower end of connecting rod 11,12 is the articulated section 4 of tabular, and latch 5 is fixed on the brace 2 after passing articulated section 4.
Referring to Fig. 3 and Fig. 4; When the door lock of box-type substation is in closed condition; This moment, the end of connecting rod 11 was higher than the height of the shop front, and connecting rod 12 ends are lower than the lower surface of the shop front, and connecting rod 11, the 12 inboard opposite house of cabinet that tightly reclines has played better fixed effect; On the door back side, also be provided with guide pad 6, connecting rod 11,12 is through in the hole of guide pad 6.When the cabinet door was opened, lock core rotated, and drives brace 2 connecting rod 11 is moved downward along guide pad 6; Connecting rod 12 moves upward along guide pad; Make the end of connecting rod 11 be lower than the upper surface of the shop front, connecting rod 12 ends are higher than the lower surface of the shop front, and the fixation of 11,12 pairs of cabinet doors of connecting rod disappears.
