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 single-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 single-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 single-phase electric energy metering device, this cylinder lock comprises lock core, lock housing and pellet shot from a slingshot device, described lock core is arranged in the cavity of lock housing inside, the front end of described lock housing is provided with keyhole, described pellet shot from a slingshot device is arranged in the lock core, described lock core comprises lock core cover and lock core rotating shaft, described lock core cover is fixedlyed connected with lock housing, described lock core rotating shaft is located in the lock core cover, and stretched out by the rear end of lock core cover, the front end of lock core rotating shaft is over against keyhole, and the lock core rotating shaft is fixing by pellet shot from a slingshot device and lock core cover.
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.
Described lock core cover rear end face is provided with the pellet shot from a slingshot holddown groove, the corresponding position of described lock core rotating shaft is provided with lock hole, one end of described pellet shot from a slingshot device is fixed in the pellet shot from a slingshot holddown groove, the other end passes lock hole locking lock core rotating shaft corresponding in the lock core rotating shaft, when key inserts, the pellet shot from a slingshot device leaves lock hole under the key effect, make the lock core rotating shaft freely to rotate.
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.
Compared with prior art, the parts that the utility model relates to are less, and reasonable and compact in structure is easy to use, and in the safety of lockset, also increase, and are fit to promote the use of on a large scale.
