Description

A kind of Electric cabinet lock
Technical field
The utility model relates to field of lockset, in particular to a kind of Electric cabinet lock.
Background technology
Regulator cubicle, or in power distribution cabinet, electric fixtures is installed, need locker to be installed on regulator cubicle door to protect the electric fixtures in it.The locker similar of traditional type in latch or bolt, this type of locker safety, reliable in be short of to some extent.Existing electric cabinet lock buckle device is various in style, Various Functions, structure differs from one another, and in this numerous species structure, uses more still gear linkage type Structural lock at present, as the patent of CN201753546U, it comprises gear, rotating shaft, upper and lower bolt, drive two tooth bars of upper and lower bolt movement respectively, the formations such as lock core.Although this kind of phase-locked bolt-type for traditional type or door latch type Structural lock buckle device, have safe and reliable feature.But, but this kind of lock also exists complex structure, maintenance, repair inconvenience, and the deficiency that cost of manufacture is higher.
Summary of the invention
The technical problem that the utility model solves: the locker on regulator cubicle door, the bolt-type of traditional type or door latch type structure lack safety and reliability, and existing gear linkage type Structural lock is too complicated, maintenance, repair inconvenience, and cost of manufacture is higher.
The utility model provides following technical scheme: a kind of Electric cabinet lock, comprise lock box, be arranged on the gear in lock box, with the tooth bar of gears meshing, the first bolt be connected with tooth bar, avoid the pivotal latch components of gear, to be fixed on gear one side and to be positioned at the lock core at gear centre place, described gear another side is positioned at gear centre place and is fixed with axle, described lock box trailing flank offers through hole, described axle engages with through hole and axle can rotate and stretching motion in through hole, the axial length of described rack and pinion contact is greater than the axial length of latch components and Gear Contact, described axle is set with coil tension spring, described coil tension spring circle is between gear another side and lock box trailing flank.
During concrete operations, described Electric cabinet lock is arranged on the door of regulator cubicle, key inserts in the strip key hole on lock core by operating personnel, rotary locking cylinder, i.e. swing pinion, the gear of rotation makes the tooth bar moving linearly engaged with it, the connected first bolt moving linearly of rack drives, first bolt can insert the inside sidewalls of regulator cubicle, to reach the object that electric cabinet lock closes.In the process of above-mentioned rotation, described latch components can avoid gear to turn round, and tooth bar can be avoided to do reverse linear motion, the first bolt can be avoided to depart from the inside sidewalls of regulator cubicle.When regulator cubicle door need be opened, key inserts in the strip key hole on lock core by operating personnel, and enforce lock core, lock core moves inward, and lock core driven gear moves inward, and the distance of movement is controlled by pre-designed coil tension spring, axial length due to rack and pinion contact is greater than the axial length of latch components and Gear Contact, therefore, when latch components and gear depart from, tooth bar still with Gear Contact.Now, namely while operating personnel keep certain thrust, revolution lock core, i.e. swiveling gear, pivotal gear makes the tooth bar engaged with it make reverse linear to move, connected first bolt of rack drives does reverse linear motion, and the first bolt can depart from the inside sidewalls of regulator cubicle, to reach the object that regulator cubicle door is opened.By technique scheme, described Electric cabinet lock mainly comprises rack-and-pinion and latch components, and relative to bolt-type or the door latch type structure of traditional type, the utility model has good safety and reliability; Relative to existing baroque gear linkage type Structural lock, relatively simple for structure, maintenance, safeguard quite convenient, cost of manufacture is lower, operates also more convenient.
As further restriction of the present utility model, described latch components comprises the lock dog with the tooth contact of gear, described lock dog is sleeved on fixed axis, between described lock dog and fixed axis, torque spring is installed, described fixed axis is fixed on lock box, described latch components also comprises makes lock dog can only along the limited block of fixed axis single direction rotation, and described limited block is fixed on lock box.When the sealed regulator cubicle door of Electric cabinet lock, it take fixed axis as the rotary motion that axis of rotation does back and forth that the tooth of the gear rotated stirs lock dog, but described lock dog can snap in the groove between tooth and tooth, when gear turns round, under the effect of limited block, lock dog can not be that axis of rotation rotates with fixed axis, and the lock dog be stuck in the groove between tooth and tooth props up gear, to limit its revolution.
As further improvement of the utility model, described Electric cabinet lock also comprises the second bolt be fixed on lock core, described lock box offers the groove rotated for the second bolt.Second bolt can rotate with lock core and gear, rotatable enter the inside sidewalls of regulator cubicle, to reach the object of sealed regulator cubicle door.
As further improvement of the utility model, the leading flank of described lock box is provided with inwardly outstanding support ring, and described lock core can be sleeved in support ring, described support ring offers the groove rotated for the second bolt.
