Abstract
The invention discloses a kind of distribution cabinet door lock construction and its assemble method, including lock housing, lock housing is step circles column construction, through door body after locked using conductive locking nut, locking nut contact door body face is provided with bore spine portion.The present invention sets bore spine portion by contacting the surface of cabinet door in locking nut, cabinet surface skin of paint is punctured during being locked during installation by locking nut, ensure that bore spine portion effectively contacts cabinet in-vivo metal, when measuring door lock ground resistance, locking nut need not be dismantled and individually remove skin of paint, operation greatly simplifies, effectively cabinet door at door lock is avoided to get rusty, improve cabinet door service life, bore spine portion can reliably contact cabinet door interior metal, when door lock is measured with cabinet door ground resistance, conductive contact is more reliable, ground resistance measurement is inaccurate, the present invention also has the characteristics that simple in structure and cheap.
Description
Technical field
The invention belongs to power distribution cabinet technical field, is related to a kind of distribution cabinet door lock construction and its assemble method.
Background technology
Existing power distribution cabinet installs door lock, has particular/special requirement to the ground resistance of door lock, ground resistance is not above state
Family's required standard value, and existing power distribution cabinet door body would generally brush one layer of paint for anti-corrosion on surface, in connecing for measurement door lock
, it is necessary to which the locking nut of door lock is unclamped during ground resistance, remove skin of paint and locking locking nut and tightly sticker door in-vivo metal,
Which is cumbersome, and large area removes paint-removing, easily leads to and gets rusty herein, the service life for reducing cabinet door and locking nut connects
Touching can be because cabinet door surface irregularity causes conductive contact unreliable, and ground resistance measurement is inaccurate.
The content of the invention
The technical problem to be solved in the present invention is：A kind of distribution cabinet door lock construction and its assemble method are provided, solved existing
There is cumbersome, large area present in technology to go paint-removing, the service life for easily leading to cabinet door of getting rusty, reduce herein, locking
Nut contact can cause the problem of conductive contact is unreliable, ground resistance measurement is inaccurate because of cabinet door surface irregularity.
The technical solution that the present invention takes is：A kind of distribution cabinet door lock construction, including lock housing, lock housing are step circles cylindricality knot
Structure, through door body after locked using conductive locking nut, locking nut contact door body face is provided with bore spine portion.
Preferably, above-mentioned bore spine portion is ARROW structure, and direction is locked in tip towards locking nut.
Preferably, the tip in above-mentioned bore spine portion is provided with slope sword.
Preferably, above-mentioned bore spine portion sets 4-8.
Preferably, above-mentioned slope cutting edge inclination is 5-10 degree.
A kind of assemble method of distribution cabinet door lock construction, this method are：Lock housing is penetrated in door body through hole, step is resisted against
Door body outer end, the inner screw in locking nut, until bore spine portion punctures door body surface skin of paint and keeps connecing with door in-vivo metal
Touch.
Beneficial effects of the present invention：Compared with prior art, the present invention is set by contacting the surface of cabinet door in locking nut
Put bore spine portion, when installation locked by locking nut during puncture cabinet surface skin of paint, it is ensured that bore spine portion effectively contacts cabinet
In-vivo metal, when measuring door lock ground resistance, without dismantling locking nut and individually removing skin of paint, operation is greatly simplified, had
Effect avoids cabinet door at door lock from getting rusty, and improves cabinet door service life, and bore spine portion can reliably contact cabinet door interior metal, door lock with
When cabinet door ground resistance measures, conductive contact is more reliable, and ground resistance measurement is inaccurate, efficiently solves and exists in the prior art
Cumbersome, large area go paint-removing, easily lead to get rusty herein, the contact of the service life that reduces cabinet door, locking nut can be because
Cabinet door surface irregularity causes the problem of conductive contact is unreliable, ground resistance measurement is inaccurate, and the present invention also has structure letter
The characteristics of single and cheap.

Embodiment
Below in conjunction with the accompanying drawings and invention is described further in specific embodiment.
Embodiment 1：As Figure 1-Figure 4, a kind of distribution cabinet door lock construction, including lock housing 1, lock housing 1 are step circles cylindricality
Structure, through door body 2 after locked using conductive locking nut 3, locking nut 3 contacts 2 face of door body and is provided with bore spine portion 4, lock housing 1
In be provided with rotation lock shaft 6, rotate lock shaft 6 on be provided with lock tongue 5, symmetrical clamping plane 7 is provided with lock housing 1, easy to fill
Unload door lock.
Preferably, above-mentioned bore spine portion 4 is ARROW structure, and direction is locked in tip towards locking nut 3, easy to quickly realize oil
The cutting of enamelled coating, more rotating nuts are more time saving and energy saving.
Preferably, the tip in above-mentioned bore spine portion 4 is provided with slope sword 8, and beneficial to cutting skin of paint, realization quickly punctures, tiltedly
In the sword insertion door in-vivo metal of slope, contact is more reliable.
Preferably, above-mentioned bore spine portion 4 sets 4-8, and contact is reliable and stable, preferably 6.
Preferably, above-mentioned 8 inclination angle of slope sword is 5-10 degree, and rotation power-saving, contact is reliably.
Embodiment 2：A kind of assemble method of distribution cabinet door lock construction, this method are：Lock housing 1 is penetrated in 2 through hole of door body,
Step is resisted against 2 outer end of door body, and the inner screws in locking nut 3, until bore spine portion 4 puncture 2 surface skin of paint of door body and with door
Metal keeps contact in body 2.
During measurement, door lock is electrically connected with cabinet door, and cabinet door is electrically connected with cabinet, and cabinet is connected to ground, and ground resistance meter connects when measuring
Connect door lock, you can realize that door lock ground resistance measures.
The above description is merely a specific embodiment, but protection scope of the present invention is not limited thereto, any
Those familiar with the art the invention discloses technical scope in, change or replacement can be readily occurred in, should all be contained
Cover within protection scope of the present invention, therefore, protection scope of the present invention should be based on the protection scope of the described claims.
