Abstract
The utility model discloses a case becomes internal switch cabinet lock structure, include: lock tube, lock core, bolt, spring bolt, the adoption door of screw structure, the screw lock core is nut that matches with the screw rod lock core of embedding on with the cubical switchboard stand, after the door plant is close, in the embedded nut of screw lock core directness screw in to the mesh that the realization was locked a door. Receive when jolting at box -type substation like this, the screw lock never can be opened automatically to the safety of the equipment of having guaranteed no longer receives the damage.
Description
Technical field
The utility model relates to the construction applications of YBW series box-type substation internal switch cabinet door lock, particularly relates to case and becomes internal switch cabinet door lock structure.
Background technology
The lock for door of switch cabinet of traditional box-type substation inside all adopts dead bolt structure, is exactly to be rotated by lock core to drive dead bolt to rotate 90 degree, thus the function that realization is locked a door and opened the door.But because box-type substation is subject in transit violent jolting, the lock for door of switch cabinet being contained in the inside is opened very easily automatically, once door-lock opening, due to the effect of severe jolt, the element that door board of switch cabinet and door-plate fill will all damage, thus cause huge economic loss, more seriously can affect construction period and produce a series of quality problems.
Summary of the invention
For the deficiency of prior art, the purpose of this utility model box type transformation that is to give security stands in when being subject to violent jolting, and internal switch cabinet door can not be opened automatically, ensures that door-plate and element can not damage, is intended to solve above-mentioned disadvantage.
In order to solve the problems of the technologies described above, the utility model is achieved through the following technical solutions:
Case becomes internal switch cabinet door lock structure, comprise: lock tube, lock core, bolt, dead bolt, the described door that have employed screw structure, screw lock core embeds a nut matched with screw rod lock core by switch cabinet vertical pole, after door-plate is shut, screw lock core is directly screwed in embedded nut, thus the object that realization is locked a door.Like this when box-type substation is subject to jolting, screw door lock will not be opened automatically, thus ensure that the safety of equipment, is no longer damaged.
Accompanying drawing explanation
Fig. 1 is prior art structural representation;
Fig. 2 is the utility model structural representation.
Number in the figure explanation
1-lock tube;
2-lock core;
3-bolt;
4-dead bolt;
5-screw lock core.
Detailed description of the invention
Below in conjunction with accompanying drawing and detailed description of the invention, the utility model is described in further detail:
As shown in Figure 1, originally door latch structure is dead bolt structure, and lock tube 1 is fixed on door-plate by nut, and lock core 2 is connected by a square hole with dead bolt 4, then is compressed through bolt 3, locking door on the column that dead bolt 4 is stuck in switchboard.But dead bolt 4 can rotate when being subject to jolting, namely door-plate can be opened.
As shown in Figure 2, the utility model have employed the door lock of screw structure, first embeds a nut matched with screw rod lock core by switch cabinet vertical pole, after door-plate is shut, is directly screwed in embedded nut by screw lock core 5, thus the object that realization is locked a door.Like this when box-type substation is subject to jolting, the screw door lock of figure bis-will not be opened automatically, thus ensure that the safety of equipment, is no longer damaged.
Claims (1)
1. case becomes internal switch cabinet door lock structure, comprise: lock tube, lock core, bolt, dead bolt, it is characterized in that: the described door that have employed screw structure, screw lock core embeds a nut matched with screw rod lock core by switch cabinet vertical pole, after door-plate is shut, screw lock core is directly screwed in embedded nut, thus the object that realization is locked a door.
