Description

A kind of door lock, box type substation door and case variant substation

Technical field

The utility model relates to door lock assembly technical fields, and in particular to a kind of door lock, box type substation door and case variant substation.

Background technique

Box type transformer is equivalent to Small Substation, belongs to power distribution station, directly provides a user power supply, box type transformer because With small in size, light-weight, low noise, low-loss, high reliability, it is widely used in residential quarters, commercial center, enterprise, The places such as school.Box type transformer has box type substation door, and personnel arbitrarily open box type substation door and cause the accident in order to prevent, and box type substation door is intended to add Fill door lock.And since box type transformer uses outdoors, rainwater is easy to immerse door lock, and rainwater intrusion door lock will cause door lock Corrosion, and when environment temperature is subzero, the rainwater of immersion freezes in door lock will cause door lock to open difficulty；Therefore, The door lock of box type substation door is to prevent rainwater from immersing, and needs to fill rain insensitive device.Box type substation door in the prior art lock generally by lock box shell, Lock core, box cover composition, box type substation door are locked and are embedded on the panel of box type substation door.Common rain insensitive device is independent in the external face of lock box Add a rain insensitive device, the modes such as rain insensitive device upper end hinge are fixed on cabinet, are opened by lower section, the disadvantage is that rain insensitive device It is excessive to protrude cabinet door face board, influences beauty, it is especially not applicable when being required for the box sizes that case becomes, and process inconvenience. Another box cover of lock box body as rain insensitive device, this box type substation door lock in use, start box cover below lock box body with hand, with The unlatching of door lock is carried out, but in door lock opening process, it is necessary to a hand control box cover in order to avoid falling and influencing door lock It opens, another hand opening door lock is inconvenient for operation.

Utility model content

Therefore, it the technical problem to be solved by the present invention is to overcome the problems, such as that existing door lock unlocking is inconvenient, provides One kind having rainproof function, and convenient door lock of unlocking, and is provided with box type substation door and the case variant substation of the door lock.

To solve the above problems, a kind of door lock of the utility model, including lock box body, box cover, lock core and handle.Lock box body The setting of insertion has lock box chamber on door-plate；Box cover is arranged on the lock box body, the company of the box cover and the lock box body Connecing end is first rotating shaft, and the box cover is rotated around the first rotating shaft, to open or close the lock box chamber；Lock core is arranged in institute It is intracavitary to state lock box, for unlocking or shutting；Handle is fixedly connected with the lock core, and the mobile handle drives the lock core dynamic Make, to unlock or shut；During unlocking, the handle stretches out the lock box body.

The lock core is located at the lower part of the lock box chamber, and when shutting state, the handle setting is intracavitary in the lock box.

The connecting pin of the handle and the lock core is the second shaft, and the handle is around the relatively described lock of second shaft When core rotates, the lock core is failure to actuate；When the handle is circumferentially moved centered on second shaft, the lock core movement, To unlock or shut.

The one end of the handle far from the lock core is grip part, when the handle stretches out the lock box body, the gripping Portion is located at the outside of the lock box body.

It further include that the intracavitary locked component of the lock box is set, the locked component is by the handle locking in the lock Box is intracavitary.

The locked component includes: plug connector, is arranged on the inner wall far from the box cover of the lock box body, is N-shaped, The top of the plug connector is towards the box cover；Through slot is arranged on the handle, and the plug connector may pass through the perforation Slot；Latch fitting is inserted into the inner cavity of the plug connector, after the plug connector passes through the through slot to prevent the grafting Part is removed from the through slot.

The through slot is arranged along the length direction of the handle, and the latch fitting is padlock.

It further include the upper lock rod being connect with the lock core being arranged in the door-plate and lower locking bar, doorframe has upper locked groove With lower locked groove；The lock core turns to when shutting state, and the upper lock rod is extend into the upper locked groove, and the lower locking bar protrudes into Into the lower locked groove；When the lock core turns to unlocking condition, the upper lock rod is removed out of described upper locked groove, the lower lock Bar is removed out of described lower locked groove.

A kind of box type substation door of the utility model, including above-mentioned door lock, doorframe and door-plate, door-plate is arranged in the doorframe, With the door lock.

It further include enabling lamp, and travel switch when setting between the door-plate and the doorframe, in the door-plate phase When rotating set distance to the doorframe, travel switch movement, it is bright that the enabling lamp is arranged in control.

The one plants case variant substation of the utility model has above-mentioned box type substation door.

Technical solutions of the utility model have the advantages that
