Abstract

The invention relates to an electric power measuring box lock which mainly comprises a magnetic coded lock, a shifting piece and a pin. The electric power measuring box lock is characterized in that a right-angle spring bolt is disposed on the lower portion of the lock cylinder of the magnetic coded lock disposed in a lock box. A clamp pin is disposed on the inner wall of the lock box. The clamp pin extends into a clamp groove peripherally disposed on the outer wall of the lock cylinder. The shifting piece connected with the pin is disposed at the end of a rotary shaft. The other end of the rotary shaft is hinged to the end of a handle. The electric power measuring box lock has the advantages that key fatigue breaking caused by long-term hard key turning can be avoided, and the lock is simple in structure and convenient to use and operate.

Description

Electric metering box lockset

Technical field

The present invention relates to a kind of power equipment component, particularly a kind of electric metering box lockset.

Background technology

Existing electric metering box adopts the good magnetic cipher lock of safety more, its basic structure is that the lock core of lockset is provided with a circular plectrum, on plectrum, be connected with respectively upper and lower two pin rods, just that chamber door is locked in the hole of pin rod head insertion casing relevant position, after key is inserted to lockhole and unblanks, twisting key band movable lock core rotates, the plectrum arranging on lock core will drive upper and lower two pin rods to move round about simultaneously, with the object that reaches locking or unblank, because most electric metering boxes are all arranged on outdoor, therefore the pin rod of its lockset, plectrum and other positions are easy to produce corrosion, while making to unblank, the rotation of lock core is obstructed, operating personnel has to firmly to twist for a long time key and unblanks, thereby make the spoon bar on key produce metal fatigue so that fracture, cause chamber door to open, lockset also cannot continue to use.

Summary of the invention

The object of the invention is to overcome the deficiencies in the prior art, a kind of electric metering box lockset being suitable in outdoor application is provided.

The object of the present invention is achieved like this: a kind of electric metering box lockset, mainly by magnetic cipher lock, plectrum and pin rod form, the lock core bottom that it is characterized in that being arranged on the magnetic cipher lock in lock box is provided with a rectangular-shaped dead bolt, the bottom bar of dead bolt is provided with a chamfer dovetail groove, the nose bar that lock core bottom arranges is against on the inclined-plane of chamfer dovetail groove, the tongue hook of dead bolt one end is positioned at the end of handle groove, the inwall of lock box is provided with a bayonet lock, bayonet lock extend in the circumferential draw-in groove arranging of outer wall of lock core, draw-in groove is communicated with and is formed by the groove of two ends different in width, the plectrum that is connected with pin rod is arranged on the end of a rotating shaft, the end of the other end of rotating shaft and a handle is hinged, the other end of handle is provided with a shrinkage pool.

On the hinge axis being connected with rotating shaft at tail end, lock core edge lug boss bottom and the handle of dead bolt, be equipped with back-moving spring.

The present invention is in the time of turns on power metering chamber door, do not need to rely on again turn twist key drive plectrum and pin rod, rotate plectrum and pin rod but be provided with special handle, thereby can avoid causing key fatigue fracture because firmly turning for a long time key, even if some positions of lockset corrosion to some extent, handle still can easily be opened chamber door and can not damage lockset, and the present invention is simple in structure, uses easy to operate.

Accompanying drawing explanation

Fig. 1 is the structural representation of handle blocking of the present invention;

Fig. 2 is the partial sectional view after lock core of the present invention is opened.

The specific embodiment

Below in conjunction with accompanying drawing, the invention will be further described:

As shown in Figure 1, 2, the present invention is arranged on electric-power metering box door plate 18, is mainly made up of magnetic cipher lock, plectrum 1 and pin rod 2.The lock core 3 of magnetic cipher lock is arranged in lock box 4, the boss bottom at lock core edge is provided with back-moving spring 5, the bottom of lock core is provided with a rectangular-shaped dead bolt 6, the bottom bar of dead bolt is provided with a chamfer dovetail groove 7, the nose bar 8 that lock core bottom arranges is against on the inclined-plane of chamfer dovetail groove, and the tongue hook 9 of dead bolt one end is positioned at the end of handle groove 10.The inwall of lock box is provided with a bayonet lock 11, and bayonet lock extend in the draw-in groove that outer wall of lock core circumferentially arranges 12, and draw-in groove is communicated with and is formed by the groove of two ends different in width, and the draw-in groove providing in Fig. 2 is the part that its width is larger.

The plectrum that is connected with pin rod is arranged on the end of a rotating shaft 13, and the end of the other end of rotating shaft and a handle 14 is hinged, and the other end of handle is provided with a shrinkage pool 15.

Be provided with back-moving spring 16 at the tail end of dead bolt, on the hinge axis being connected with rotating shaft at handle, be provided with back-moving spring 17.

Under the state of metering chamber door locking, handle is arranged in handle groove, and now the latch hook on dead bolt stretches in the shrinkage pool of handle end handle is fixed.While opening metering chamber door, insert key 19 rotational lock cores to enable possition, now, lock core rotates and makes the wider portion of draw-in groove on its outer wall go to the bayonet lock place of lock box inwall, thereby lock core can be moved along its axis, press key, lock core also moves down, lock core bottom is against in dead bolt bottom bar groove the nose bar on inclined-plane and promotes dead bolt and be subjected to displacement, make tongue hook on dead bolt shift out the shrinkage pool of handle end, handle is upspring under the effect of back-moving spring, turn handle, drive rotating shaft, plectrum rotates, drive pin rod retraction mobile simultaneously, pin rod head deviates from the lockhole on casing, door can be opened.When locking chamber door, first turn handle makes pin rod locking, press again lower handle to handle groove, the dead bolt tongue hook having resetted snaps in the shrinkage pool of handle end handle is fixed, and then rotate key drive the lock core having resetted to locked position of coupler, now, on outer wall of lock core, the narrower part of draw-in groove goes to the bayonet lock place of lock box inwall, lock core can not be moved vertically again, therefore cannot trigger handle and eject.

Claims
