Description

The outdoor lock of high and low voltage switch cabinet

Technical field

The utility model relates to a kind of door lock, the outdoor lock of particularly a kind of high and low voltage switch cabinet.

Background technology

The high and low voltage switch cabinet is the visual plant that uses in the power supply-distribution system, for safe in utilization, needs to take the mode strict control of interlocking sometimes, prior art can only realize interlocking to equipment with two lock sets, and not only complex structure influences attractive in appearance, and the lock long term exposure outside, corrosion easily.Though at present the high and low voltage switch cabinet uses more push-plate type door lock compact conformation, good looking appearance, all is monolock, can not interlocking, promptly key is inserted keyhole and unblank with one, rotate the lock jumping handle that takeoffs and can open the cabinet door.

Summary of the invention

The purpose of this utility model is to improve on the basis of former push-plate type door lock, provides a kind of safe in utilization, reliable, has the outdoor lock of high and low voltage switch cabinet of interlock function, to overcome the existing above-mentioned deficiency of prior art.

The utility model take technical scheme be: the outdoor lock of a kind of high and low voltage switch cabinet, comprise lock body, main lock, lock is jumped handle and jam plate, lock body is the housing that has a microscler inner chamber, main lock is installed in the bottom of lock body inner chamber, the upper end that lock is jumped handle is connected with the jam plate at lock body rear portion by the spacing turning cylinder that is installed in lock body inner chamber top, lock when jumping the handle pressing the capping of lock body inner chamber, the snap close of its lower end is by the locking of the dead bolt of main lock, described lock body middle part is equipped with a secondary lock, the lock core of secondary lock is positioned at lock body inner chamber middle part, the lock pin of being opened by secondary lock pin is positioned at the lock body rear portion, described jam plate is by orthogonal, and plate fond of gossip that fuses and short hyoplastron formation, jam plate is connected with spacing turning cylinder by the square hole of its length hyoplastron connecting part, when lock is jumped handle pressing locking, jump the jam plate that handle drives rotation with locking, its plate fond of gossip is in level, and the lock pin that short hyoplastron is ejected secondary lock pin keeps off dead.

Its further technical scheme is: described secondary lock is connected with lock body by welding or screw.

Its further technical scheme be: described main lock is the waterproofing protection lock, is provided with waterproofing protection before its keyhole and covers.

Owing to take technique scheme, the outdoor lockset of the high and low voltage switch cabinet of the utility model has following good effect: because the outdoor lock of the high and low voltage switch cabinet of the utility model has been set up secondary lock, cooperate with the jam plate after improving, its secondary lock is installed in the inner chamber middle part of former push-plate type Door lock, do not change the contour structures of former push-plate type door lock, both kept former push-plate type door latch structure compactness, attractive in appearance, the function of anti-corrosion reaches the purpose that realizes interlocking with a lock again; This lock not only can be used for the high and low voltage switch cabinet, also can be used for the electrical equipment rack that other need interlocking.

Be further described below in conjunction with the technical characterictic of drawings and Examples the outdoor lock of high and low voltage switch cabinet of the utility model.

The specific embodiment

The outdoor lock of a kind of high and low voltage switch cabinet, comprise lock body 1, main lock 3, lock is jumped handle 2 and jam plate 5, lock body 1 is for having the housing of a microscler inner chamber, main lock 3 is installed in the bottom of lock body inner chamber, the upper end that lock is jumped handle 2 is connected with the jam plate 5 at lock body rear portion by the spacing turning cylinder 6 that is installed in lock body inner chamber top, lock when jumping handle 2 pressings lock body 1 inner chamber capping, the snap close 21 of its lower end is by dead bolt 31 lockings of main lock, described lock body 1 middle part is equipped with a secondary lock 4, the lock core of secondary lock is positioned at lock body inner chamber middle part, the lock pin of being opened by secondary lock pin 41 is positioned at the lock body rear portion, described jam plate 5 is by orthogonal, and plate fond of gossip 51 that fuses and short hyoplastron 52 formations, jam plate 5 is connected with spacing turning cylinder 6 by the square hole of its length hyoplastron connecting part, when lock is jumped handle 2 pressings locking, jump the jam plate 5 that handle 2 drives are rotated with lock, the lock pin 41 that the locked groove after its plate 51 fond of gossip is in level and sticks into doorframe, short hyoplastron 52 are ejected secondary lock 4 lock cores keeps off dead.

Described secondary lock is connected with lock body by the mode of welding; Described main lock is the waterproofing protection lock, is provided with the waterproofing protection lid before its keyhole.

In the foregoing description, described secondary lock can be selected the tongue lock that one drawer uses for use, also available one padlock, but its mounting means will change slightly, and the short hyoplastron that can keep off deadlock plates when snap close is locked gets final product.Secondary lock also can be connected with lock body by the mode of screwing.

The outdoor lock installation and application of the high and low voltage switch cabinet of the utility model: the outdoor lock of this high and low voltage switch cabinet is installed on the cabinet door, before non-locking, inhour is rotated lock and is jumped 90 ° on handle, make the plate fond of gossip 51 of jam plate be in plumbness, short hyoplastron 52 is in level, the tension of cabinet door is closed up, positive then hour hands rotation lock is jumped 90 ° on handle, locked groove after making the plate fond of gossip 51 of jam plate be in level and stick into doorframe, this moment, short hyoplastron forwarded plumbness to 52 times, with key revolute pair lock 4, make the lock pin 41 of secondary lock pin back eject short hyoplastron 52 retainings of jam plate dead, extract key out, will lock then and jump handle 2 and depress the dead bolt 31 that makes main lock and stick into lock and jump the snap close 21 of handle, at its lower end and lock, simultaneously pair is locked 4 cappings.In the time of need opening the door, opening main lock 3 earlier makes lock jump handle 2 ejections, because the restriction of spacing turning cylinder 6, jam plate 5 can only positive and negative rotation 90 °, and this moment is dead so can not rotate by lock pin 41 retainings of secondary lock 4 because of the short hyoplastron 52 of jam plate, needs to lock 4 with the key open auxiliary, make secondary lock pin 41 indentations of locking the back leave the gear of short hyoplastron 52, inhour is rotated lock and is jumped 90 ° on handle again, makes the locked groove after the plate fond of gossip 51 of jam plate withdraws from doorframe, and the cabinet door can be pushed open.
