Description
Technical field
The utility model belongs to safety switch and field of lockset, and in particular to a kind of self-shield lockset, also relates to one
Power distribution cabinet of the kind containing the self-shield lockset.
Background technology
Power distribution cabinet is used for the distribution operation of transformer station or plant equipment, and inside includes a large amount of charging equipments, on the one hand in order to
It is easy to maintenance, it is necessary to periodically carry out maintenance and inspection to power distribution cabinet internal unit, therefore should be easy to open and close, the opposing party
Face, because internal unit is complicated, and often contain high pressure or heavy current, therefore there should be preferably protection work(after its closing
Can, prevent in the situation for being caused cabinet door to open or can not open by the reason for external force or internal accident.And above-mentioned both sides
Demand can only usually meet on the one hand thus to attend to one thing and lose sight of another, and in actual use, lockset often occur because frequently opening
The long-term stress of conjunction and fatigue deformation occurs, and should limiting damage caused by short time forceful action, ultimately result in lockset
Can not normal use.
Utility model content
In view of the above-mentioned problems, the purpose of this utility model is, there is provided a kind of lockset with self-protection function, the lockset
It is simple in construction, destroyed probability can be reduced.
To achieve the above object, the utility model adopts the following technical scheme that.
A kind of self-shield lockset, including dead bolt, the dead bolt are provided with through hole, in addition to the mounting shell that a section is U-shaped,

Dynamic locking plate is dug in the region corresponding with position of mounting hole via, so that back-off can pass through the through hole on the via and dead bolt
It is connected with dead bolt.
Principle of the present utility model and have the beneficial effect that
1. original fixed lock plate structure is arranged into bascule, by protecting the deformation and recovery of spring, protect
Card acts in lockset by external force, and when causing dead bolt and the generation relative displacement of movable locking plate, movable locking plate can avoid automatically, keep away
Exempt to occur strongly to collide therebetween, prevent that such a situation is applied to lockset by smaller because strength collision causes deformation failure
The effect of frequently external force when avoid fatigue rupture or abrasion, by setting lockset size and protection spring force size can be with
It is arranged as required to deform protection.
2. setting back-off on the basis of said structure, through hole is set on dead bolt, once lockset is by bigger effect
When the impact mitigation measure such as power, the deformation of existing structure can not avoid contacting firmly, back-off can pass through the via on movable locking plate
Dead bolt is clasped with through hole, prevents from coming off, above-mentioned hard contact situation one kind is that the inside downthrust of external force causes, and is prevented by locked
Internal unit is damaged, and another situation is that device interior power acts on outwardly, such as power distribution cabinet internal high pressure forceful electric power or room implosion
Other pressure such as air pressure inside increase suddenly caused by fried and other situations, and now, the locking function can not only prevent brokenly
Bad further diffusion causes bigger harm, meanwhile, dead bolt is locked to the back-off opening position away from former latched position, now lockset
The structures such as corresponding door and window can open sub-fraction, and (opening degree can be set by adjusting protection spring and back-off position
Put), therefore in above-mentioned unexpected generation, voluntarily can slowly unload internal pressure, in the case of timely processing is unable to, help
In the internal accident deterioration degree of mitigation.
Further optimization includes to such scheme, and the first installation cavity, the movable locking plate are provided with the mounting shell

Buffer capacity, magnet and protection spring, which are combined, can simplify structure, realize more free regulatory function.
Further, the mounting shell is provided with the first installation position of cyclic structure, and the movable locking plate is in relevant position
The second installation position provided with counterbore shape, the protection spring are located between the first installation position and the second installation position, pacified by setting
Dress position positions to protection spring, prevents during frequent use, and spring, which comes off, causes lockset defencive function to fail.
Further, the movable locking plate is formed by elastomeric material through crimping, using elastomeric material creative activity locking plate, is
Movable locking plate possesses necessarily from deformability, improves the instant reacting condition speed of lockset, mitigates frictional impact.
Further, the movable locking plate is U-shaped elastic construction, and the via is proper middle located at U-shaped bottom, ibid, U
Property structure further raising activity locking plate deformability, while U-shaped inner chamber also allows for the installation of back-off.
Apply a kind of power distribution cabinet of above-mentioned lockset, including self-shield lockset, in addition to cabinet, cabinet door.
Further, the power distribution cabinet is between the mounting shell and movable locking plate of self-shield lockset, or movable locking plate and
Range sensor or pressure sensor are provided between locked component, the power distribution cabinet is additionally provided with warning lamp or acoustical generator, is based on
Above-mentioned lockset defencive function, by setting sensor to enable power distribution cabinet immediate feedback while possessing self-protection function
Various information, improve lockset and power distribution cabinet usability.
