Abstract
The utility model relates to a three-phase electric energy metering device dedicated anti-electricity-stealing door lock. The spring lock comprises a lock shell, a lock cylinder, a springing device and a lock cover. The front end surfaces of the lock shell are provided with key holes; the lock cylinder is placed in a cavity in the lock shell, and right faces the key holes; the springing device is placed on the lock cylinder; and the lock cover is movably connected on the front end surfaces of the lock shell and covers the key holes. Compared with the prior art, the three-phase electric energy metering device dedicated anti-electricity-stealing door lock has the advantages of being simple in structure, good in safety performance and the like.
Description
Technical field
The utility model relates to a kind of lockset, especially relates to the anti-electricity-theft special door lock of a kind of three-phase electric energy metering device.
Background technology
Lockset is used very general in daily life, and the various locksets of family, unit use are still based on cylinder lock at present.Existing cylinder lock is the rotation that utilizes the pellet shot from a slingshot group control lock core rotor moving up and down that the outside of lock core rotor is equipped with, and stirs dead bolt closure or openness lockset again, most billiards lock structure more complicated in the market, and component are many.Except cylinder lock, also has comparatively complicated lockset such as electronic lock, coded lock at present, though its theftproof performance is better, but because its cost is higher, structure is comparatively complicated, damage than being easier to, cause certain puzzlement to the user, particularly very inconvenient for old man and children.
The utility model content
The purpose of this utility model is exactly that a kind of simple in structure, anti-electricity-theft special door lock of three-phase electric energy metering device that safety is good is provided in order to overcome the defective that above-mentioned prior art exists
The purpose of this utility model can be achieved through the following technical solutions:
The anti-electricity-theft special door lock of a kind of three-phase electric energy metering device, this cylinder lock comprises lock housing, lock core, pellet shot from a slingshot device and locking closure, the front end face of described lock housing is provided with keyhole, described lock core is arranged in the cavity of lock housing inside, and over against keyhole, described pellet shot from a slingshot device is arranged on the lock core, and described locking closure is movably connected on the front end face of lock housing, covers keyhole.
Described pellet shot from a slingshot device is provided with at least 3 groups.
The edge of described keyhole offers a mistake proofing groove that is used for avoiding the insertion of key mistake.
This cylinder lock also comprises jump ring, and this jump ring is arranged on the lock housing rear portion, compresses the lock core that is arranged in the lock housing cavity, the position of fixed lock core.
The corresponding position at the edge of the front end face of described lock housing and locking closure edge is provided with the lockhole of mutual coupling.
Described pellet shot from a slingshot device is arranged on the lock core vertically.
Compared with prior art; the parts that the utility model relates to are less; reasonable and compact in structure; easy to use; and in the safety of lockset, also increase, be fit to promote the use of on a large scale, be provided with locking closure in addition for the protection of keyhole; and this locking closure can lock by lockhole, realizes the double locking of three phase metering case.
Description of drawings
Fig. 1 is front view of the present utility model;
Fig. 2 is rear elevation of the present utility model;
Fig. 3 is lateral view of the present utility model.
The specific embodiment
Below in conjunction with the drawings and specific embodiments the utility model is elaborated.
Embodiment
Shown in Fig. 1～3, the anti-electricity-theft special door lock of a kind of three-phase electric energy metering device, this cylinder lock comprises lock housing 1, lock core 2, pellet shot from a slingshot device 3, locking closure 4 and jump ring 5.The front end face of lock housing 1 is provided with keyhole 12, offers a mistake proofing groove 11 that is used for avoiding the insertion of key mistake at the edge of keyhole.Lock core 2 is arranged in the cavity of lock housing 1 inside, and over against keyhole 12, jump ring 5 is arranged on lock housing 1 rear portion, compresses the lock core 2 that is arranged in lock housing 1 cavity, the position of fixed lock core 2.Pellet shot from a slingshot device 3 is arranged on the lock core 2 vertically, and is positioned at the position at keyhole edge, makes when key inserts, and can drive pellet shot from a slingshot device 3, makes it no longer lock lock core 2, thus unlocking spring lock.
In order to guarantee the safety of lockset, the pellet shot from a slingshot device is provided with at least 3 groups.Locking closure 4 is movably connected on the front end face of lock housing 1, cover keyhole 12, while is in the edge of the front end face of lock housing 1 and the corresponding position at locking closure 4 edges, be provided with the lockhole 6 of mutual coupling, can be used for pinning locking closure 4, make key can't insert keyhole 12, realize the double locking of three phase metering case.
Because the parts that the utility model relates to are less, reasonable and compact in structure is easy to use, and also increases in the safety of lockset, is fit to promote the use of on a large scale.
