[0021] The following further describes the detailed implementation manners of the present utility model in conjunction with the accompanying drawings. It should be noted here that the description of these implementation manners is used to help understand the present utility model, but does not constitute a limitation to the present utility model. In addition, the technical features involved in the various implementation manners of the present utility model described below can be combined with each other as long as they do not conflict with each other.

[0022] As Figure 1-6 shown, an electric plug lock includes a housing 1, a disassembling member 2, a locking tongue member 3, a transmission mechanism 4, and a driving mechanism 5;

[0023] The disassembling member 2 is disposed inside the housing 1 and connected to the inner wall of the housing 1. The opening of the disassembling member 2 faces the locking tongue member 3, and a transmission cavity 21 is formed inside the disassembling member 2;

[0024] Both the transmission mechanism 4 and the driving mechanism 5 are disposed inside the housing 1. The telescopic shaft 51 of the driving mechanism 5 is connected to the locking tongue member 3 through the transmission mechanism 4 to drive the locking tongue member 3 to contract inside the transmission cavity 21 or extend outside the transmission cavity 21.

[0025] In the electric plug lock, by independently manufacturing the disassembling member 2, the disassembling member 2 is detachably connected to the housing 1, and the original transmission cavity 21 provided in the housing 1 is transferred to the disassembling member 2. Compared with the production method that also needs to consider the processing of the transmission cavity 21 when processing the housing 1, the processing difficulty is reduced. In this way, the processing accuracy of a single workpiece can be improved, the processing accuracy of the transmission cavity 21 can be improved, and it is ensured that the locking tongue member 3 can move smoothly in the movement cavity.

[0026] In this embodiment, both the housing 1 and the disassembling member 2 are separately processed from engineering plastics, which ensures the strength of the components. At the same time, the injection molding process can ensure the consistency of the product and does not require cleaning and powder spraying for coloring. The locking tongue member 3 is made by an insert composite injection process. The locking tongue member 3 uses 304 stainless steel as the force-bearing mechanism of the lock, and the sliding part is composite-injected with engineering plastics, which not only ensures the structural strength but also has higher consistency. During actual use, the driving mechanism 5 drives the transmission mechanism 4 to act through the telescopic shaft 51, and the transmission mechanism 4 drives the locking tongue member 3 to perform a reciprocating motion in the up and down directions, so as to realize the function that the locking tongue member 3 contracts inside the transmission cavity 21 or extends outside the transmission cavity 21, and achieve the purpose of unlocking or locking.

[0027] It is worth noting that as Figure 2-4As shown, a plurality of limiting and reinforcing ribs 11 are provided on the inner wall of the housing 1. The limiting and reinforcing ribs 11 are distributed on the front and rear sides of the disassembling part 2, and the wall surface of the limiting and reinforcing ribs 11 is matched with the outer wall of the disassembling part 2 to clamp the disassembling part 2.

On the other hand, through the cooperation of the limiting and reinforcing ribs 11 and the disassembling part 2, the purpose of tenon connection between the disassembling part 2 and the inner wall of the housing 1 can be achieved.

[0028] Preferably, as Figure 5 shown, the transmission mechanism 4 includes a first connecting rod 41 and a second connecting rod 42. The first end of the first connecting rod 41 is hinged to the telescopic shaft 51 of the driving mechanism 5. The first end of the second connecting rod 42 is hinged to the second end of the first connecting rod 41. A jacking hammer 43 is provided at the second end of the second connecting rod 42. A groove 31 is provided on the lock tongue member 3. The jacking hammer 43 is movably arranged in the groove 31. By providing the first connecting rod 41 and the second connecting rod 42 to form a swing arm structure, the force generated when the telescopic shaft 51 of the driving mechanism 5 expands and contracts is transmitted to the jacking hammer 43 of the second connecting rod 42 through the first connecting rod 41. The cooperation of the jacking hammer 43 and the groove 31 is used to jack up or press down the lock tongue member 3, so as to realize the up-and-down reciprocating movement of the lock tongue member 3. Preferably, the driving mechanism 5 is a solenoid valve.

In this way, it is convenient for the rotation support shaft 44 to rotate within the accommodation groove 22, and the rotation support shaft 44 can be prevented from disengaging from the accommodation groove 22.

[0032] Preferably, as Figure 1 shown, the electric plug lock further includes a base 7. The base 7 is connected to the bottom side of the housing 1. The base 7 is provided with a latch hole 71. The latch member 3 passes through the latch hole 71 and is slidably connected to the base 7.
