Embodiment
To describe technology contents of the present utility model, construction feature, the objects and the effects in detail, below in conjunction with implementation
Mode simultaneously coordinates accompanying drawing to be explained in detail.
Please with reference to Fig. 6-Fig. 9, understand as shown in Figure 6, a kind of preferred embodiment of the utility model is a kind of preventing fraudulent use of electricity
Magnetic padlock, including housing 100 and electromagnetic drive mechanism 200, lock hook mechanism and microswitch 500 in housing；The electricity
Magnetic driving mechanism is used to drive latch hook mechanism to unlock；The electromagnetic drive mechanism and microswitch are connected with peripheral control unit；
The latch hook mechanism includes shank 3001 and locking bar 3002, and the locking bar includes the first dead bolt 304 and the second dead bolt 305；First
Dead bolt is provided with gib head, and the gib head is the gib head 303 of locking bar, and the gib head 303 of the locking bar matches with the gib head of shank, described
The first shelter 306 is additionally provided with first dead bolt, first shelter is extended to below shank, for blocking fore shaft directly to lead to
Toward the passage of shank.As shown in fig. 6, so as to which the first shelter protects the pilferage work that the dead bolt of shank first is not stretched into by lower right
Tool is disclosed.
Reference picture 6 and Fig. 9 illustrate the course of work of the utility model theft-proof electromagnetic lock locking-in state and open mode, such as
The electromagnetic drive mechanism 200 shown in Fig. 6 includes electromagnet, spring and expansion link 201；The spring is socketed on expansion link,
Described expansion link one end is connected by connecting pole 302 with shank 3001, and the expansion link other end stretches into electromagnet, the electromagnetism
Body is connected with peripheral control unit, and peripheral control unit is powered to electromagnet, control electromagnetic drive mechanism operation；
Locking-in state：Microswitch 500 is in open circuit, and now electromagnetic drive mechanism no current flows through, residing for latch hook mechanism
Locking-in state, lock 400 is in the locked groove between the first dead bolt 304 and the second dead bolt 305；
When needing to unlock, peripheral control unit is powered to electromagnetic drive mechanism, and electromagnet is by expansion link toward electromagnet depths
Suction, so as to drive shank 3001 to be turned clockwise around the point of rotation 101, the gib head 301 of shank departs from the gib head 303 of locking bar, lock
Bar 3002 is moved around the point of rotation 102 to C directions, until to Fig. 9 released states, microswitch bullet is withstood in one end of this hour locking lever
Piece, so as to feed back unlocking information to controller.
As shown in Fig. 6 and Fig. 9, in order to reach more preferable anti-theft effect, when shank and locking bar coordinate dislocation, easily from
Side is tampered instrument and disclosed；A kind of preferred embodiment of the present utility model blocks for the both sides of first dead bolt provided with second
Thing 307, second shelter is used to block gap of the fore shaft between housing and dead bolt to the passage of shank.It is preferred at some
The gib head both sides of locking bar described in embodiment are provided with the second shelter 307；As shown in figure 9, then having prominent screening in locking bar two sides
Block material, can prevent from such as touching hook when stealing tool such as steel wire 600 or the long object of point are stretched into from fore shaft 103 with effective
Bar 3001 or shank gib head 301.
As shown in figure 8, when stealing instrument stretches into fore shaft 103 and removes to disclose shank, due to being hidden by the first shelter or second
Block material is blocked, and has then disclosed locking bar, and at this moment latch hook will rotate up motion centered on the point of rotation 102, so that the
One shelter brushes up against the gib head of drag hook, causes unblock；In order to prevent the first shelter from encountering retractor head, one kind of the present utility model
In preferred embodiment, limited block is provided with housing, the limited block is used to limit locking bar rotation.
During in order that the gib head of drag hook coordinating with locking bar, the gib head of drag hook can be dropped between the first shelter and gib head
Space, the thickness of the locking bar is more than the thickness of shank, because the gib head of so design drag hook can be easier to drop into first
Space between shelter and gib head, so that stealing instrument stretches into fore shaft when removing to disclose shank, it more difficult to touch.
Embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited, it is every
The equivalent shapes or Structural Transformation made using the utility model specification and accompanying drawing content, or directly or indirectly it is used in other
