A lock rod is installed inside a lock opening of a lock body, a lock head is connected to the upper end of the lock rod, a lock rod limit clip is installed at the lower portion of the lock rod, a lock rod sleeve is installed at the lower portion of the lock opening of the lock body, the lower end of the lock rod makes contact with a wedge board, the wedge board is fixed to a lock shaft which is installed on a lock cylinder, a key port is arranged at the outer end of the lock cylinder, a battery is installed inside an electronic key, and a power indicator lamp is installed outside the electronic key. The key port of the lock cylinder is provided with a concave-shaped bottom plane and a clamping groove, three electric contacts are installed on the key port, a plug of the electronic key is in a convex shape, the plug of the electronic key corresponds to the concave-shaped key port in appearance, and the plug of the electronic key is provided with electric contacts connected with the electric contacts of the key port. A password shaft clamping device is installed inside the lock cylinder and can clamp or loosen the rotation of a mandrel. The electronic lock of the transformer tank cover can achieve the locking of the transformer tank cover, passwords can be set, the lock is prevented from being damaged manually, and the safety performance is improved. The electric lock of the transformer tank cover is suitable for being used as a lock for locking the transformer tank cover.

Description

A kind of transformer box cover electronic lock

Technical field

The present invention is to provide the apparatus of power domain, specifically a kind of transformer box cover electronic lock.

Background technology

In order to prevent that someone from stealing transformer part, transformer box cover all is housed on existing transformer usually, and covers lock is housed at transformer tank.Existing lock for transformer box cover is frame for movement, by key, turns the lock core protrusion and breaks away from lockhole, and lock core is taken off, and locking bar is fallen, and locking bar takes out from lockhole on transformer box cover, opens transformer box cover.

This lock uses trouble, and key is general, the antitheft poor performance.

Summary of the invention

The shortcoming be latched in order to overcome existing transformer box cover, the invention provides a kind of transformer box cover electronic lock.This electronic lock contacts with lock core by electron key, and to input power in lock core, lock core, according to the program release, by turning of electron key, makes the cam rotation of lock core, pushes and breaks away from locking bar, realizes locking and opens.The suitable application of electronic lock as transformer box cover.

The scheme that technical solution problem of the present invention adopts is:

In lock body one side, be provided with fore shaft, locking bar is housed in fore shaft, the locking bar upper end is connected with tapered end, the locking bar limiting card is equipped with in bottom, in the fore shaft bottom of lock body, locking lever sleeve is housed, and locking bar interts in locking lever sleeve, lower end at locking bar contacts setting with wedge, wedge is fixed on lock shaft, and lock shaft is contained on lock core, is provided with key interface in the outer end of lock core;

Battery is housed in electron key, and the power connection indicator lamp is equipped with in outside, and electron key is flat, is provided with key plug at the front end of electron key.

The key interface of lock core has baseplane and the draw-in groove of concavity, and 3 electric contacts are housed on key interface, and the electron key plug is convex, and profile is corresponding with the key interface of concavity, and is provided with the electric contact joined with the key interface electric contact.

The cipher card axial organ is housed in lock core, blocks or unclamp the rotation of mandrel.

Good effect, the present invention passes into power supply by electron key in lock core, make the lock core release, with electron key, turn simultaneously the mandrel rotation of lock core, drive is contained in the cam rotation on mandrel, locking bar fallen or rise, realizing disengaging or the insertion of locking bar and transformer box cover lockhole, realizing the locking of transformer box cover.Be characterized in: can setting code, prevent the artificial destruction of lockset, improve safety.The suitable application of lockset as the transformer box cover locking.

The accompanying drawing explanation

Fig. 2 is lock shaft of the present invention and swash plate contact condition figure

Fig. 3 is key interface end face structure figure of the present invention

Fig. 4 is electron key head shapes figure of the present invention

In figure, 1. lock body, 2. fore shaft, 3. locking bar, 3.1. tapered end, 3.2. locking bar limited location snap ring, 4. locking lever sleeve, 5. lock core, 5.1. lock shaft, 5.2. wedge, 5.3. key interface, 6. electron key, 6.1. power supply indicator.

The specific embodiment

According to the figure, in lock body 1 one sides, be provided with fore shaft 2, locking bar 3 is housed in fore shaft, the locking bar upper end is connected with tapered end 3.1, and locking bar limiting card 3.2 is equipped with in bottom, locking lever sleeve 4 is equipped with in fore shaft bottom at lock body, locking bar interts in locking lever sleeve, with wedge 5.2, contacts setting in the lower end of locking bar, and wedge is fixed on lock shaft 5.1, lock shaft is contained on lock core 5, is provided with key interface 5.3 in the outer end of lock core;

In electron key 6, battery is housed, power supply indicator 6.1 is equipped with in outside, and electron key is flat, is provided with key plug at the front end of electron key.

Use of the present invention:

Lock body is arranged on to transformer tank and covers, cover and be provided with the tapered end hole at transformer tank, by contacting of electron key and lock core, in lock core, be filled with power supply, lock core, according to the program of the unblanking release of setting in advance, then turns electron key, the rotation of band moving mandrel, wedge is rotated, and locking bar is moved down along the wedge inclined-plane, locking bar falls together with tapered end, until locking bar limited location snap ring and fore shaft lower plane block, locking bar and tapered end break away from the lockhole of transformer box cover, can open transformer box cover.When the locking transformer box cover, lock body is aimed to the tapered end hole that transformer tank covers, then by electron key, turn the mandrel of lock core, make locking bar rise to the most significant end on wedge inclined-plane, locking bar is moved upward together with tapered end, make tapered end and locking bar pass the tapered end hole that transformer tank covers, realize the locking of transformer box cover.
