Description
Affiliated technical field:
The utility model relates to a kind of key that prevents the ammeter box of stealing and be used to open and close this ammeter box.
Background technology:
Power supply unit measures by gauging table final user's power consumption, and no matter gauging table is that mechanical type or electronic type must have openable wing, so that maintenance or modification continuous data, gauging table directly influences its metering effect as being subjected to the environmental pollution meeting simultaneously, so, in order to prevent that the gauging table continuous data is illegally modified and pollution abatement, is placed in the ammeter box of a sealing usually.Yet, the structure of traditional ammeter box comprises a housing that can hold ammeter, visible surface position with this housing is provided with an openable wing simultaneously, and be connected with hinge between a side that makes wing and the housing, opposite side is sealed by lock assembly and housing, to prevent that wing from arbitrarily being opened.But because lock is exposed outside, and be the parts that arbitrarily can obtain, so this wing is easy to arbitrarily be opened or will lock and more renews lock again after destroying, to realize that the change continuous data is the purpose of stealing.
For solving above-mentioned stealing problem; CN2282688Y has announced a kind of safe antitheft ammeter box; this ammeter box is provided with inside and outside two case lids on a rectangular casing; and interior case lid directly is fixed on the casing; have on the concave surface of case lid simultaneously in order to the window of assembling ammeter, leakage switch outside and be provided with an outstanding lock nose; on interior case lid, also offer inside and outside two lead seal holes, rectangular little outer case lid, spiral-lock on the concave surface of inner cap so that ammeter is blocked protection.The purpose of this Theft-proof kilowatt-hour meter case is to want to utilize inside and outside Double layer lid and lead sealing to stop power stealing, to reach the purpose of antitheft electricity.But, because the parts in the ammeter are more, bring difficulty for maintenance and making, also integrally-built complexity improves cost simultaneously.
In addition, Chinese patent has also been announced the technology that a kind of name is called " anti-electricity-theft ammeter box and specific purpose tool thereof " for No. 2375011, this ammeter box comprises the table tank shell and its interior installing plate is set, and be fixed on ammeter on the installing plate, the input terminal and the connecting line thereof of this ammeter are covered with baffle plate, have at least two head of screw endoporus that cave inward on the baffle plate, screw special is screwed in the head of screw endoporus with specific purpose tool, and the upper bush endoporus of specific purpose tool is identical with the head of screw cross section of screw special.This ammeter box has also reduced parts when playing antitheft electricity.Because this ammeter box is that the endoporus that utilizes specific purpose tool to extend into head of screw is finished when sealed or unlatching, even and the irregular geometric figure of endoporus, but, as long as the instrument that uses except that cylindrical and can insert the head of screw endoporus all can open it, so in a single day the anti-electricity-theft ammeter box of this kind structure is opened and will loses anti-electricity-theft function.
Summary of the invention:
The purpose of this utility model provides a kind of sealed and sleeve shaped in deep of utilizing and opens dual mode to realize anti-electricity-theft ammeter box.
Another purpose of the present utility model provides and a kind ofly is specifically designed to sealed or opens the key of above-mentioned ammeter box.
The anti-electricity-theft ammeter box that the utility model proposed, have one and be used to the housing that covers ammeter and have an open surface, the view window that the visible surface of this housing is provided with through hole and is made by transparent material is equipped with the base plate and the lock-in component that is used for base plate is locked together in housing that are used to seal this open surface on the open surface of described housing.
Described base plate is provided with the slotted hole of three pairs of symmetries, and the minor face of each slotted hole is used to install ammeter and/or lock-in component and flap that extend to the enclosure interior direction to being provided with.Described lock-in component have be arranged on the wherein a pair of flap and have externally threaded locking bolt and be installed in the inboard and lock ear that can allow locking bolt insert corresponding of case side wallboard with described locking bolt position, and can be screwed in the set nut on the described locking bolt.
Described lock ear has a hollow cylinder, and this right cylinder is in the bottom that has undergauge near the setting of flap end.Described set nut is trigone or square body or oval body or pentagon body.
A kind of key that is used to open and close above-mentioned ammeter box, this key have one and extend into rod member in the housing by the through hole on the housing, and an end of this rod member is provided with the Handheld Division, and the other end is equipped with the operating portion of able to turn on or off described lock-in component.
Described Handheld Division have one with the perpendicular transverse bar of described rod member or cruciform transverse bar or the oval-shaped ball that conveniently holds.
Described operating portion have one can extend in the described lock ear and the end reeded operating rod is set, and the external diameter of the internal diameter of described groove and set nut is complementary.
The lock-in component that the anti-electricity-theft ammeter box that the utility model proposed adopts is arranged on the deep of housing, and screwing the nut mode by key realizes opening and closing, and nut is as long as adopt irregular geometrical body, the layman can not design the key that is complementary with nut, also just ammeter box can't be opened, so the ammeter box of this kind structure has fine anti-electricity-theft function; Simultaneously, lock-in component only adopts columniform lock ear and can be inserted into the structure of the locking bolt in the lock ear, makes it have outward appearance and lower cost of manufacture preferably.
Description of drawings:
