[0024] like Figure 1-4 As shown, the utility model discloses a plug lock, including a base 1 and a top cover 2, one end of the top cover 2 is hinged to the base 1, and the other end is provided with a top cover sheet 21, and the top cover sheet 21 is provided with a top cover hole 22, the base 1 is provided with a base sheet 11, and the base sheet 11 is provided with a base hole 12, the base 1 and the top cover 2 have a closed position where the base hole 12 and the top cover hole 22 are opposite, and also include a fixed lock core 4 and a locking member 5, the base 1 is provided with a fixed box 13 and the base sheet 11 is located on the fixed box 13, and the fixed box 13 is provided with a A fixing cavity 133 is provided for accommodating the fixed lock core 4, a first lock hole 23 is provided on the top cover sheet 21, a second lock hole 32 is provided on the blocking sheet 3, and the fixed lock core 4 has a locking state of driving the locking member 5 to enter the first lock hole 23 and the second lock hole 32. When fixing the base 1 and the top cover 2, an additional padlock is not required, but a key is inserted into the fixed lock core 4, so that the locking member 5 is driven to enter the first lock hole 23 and the second lock hole 32 through the fixed lock core 4 to complete the fixation. No additional padlock is required, and a double locking effect can be formed with the padlock.
[0025] The locking member 5 is slidably disposed in the fixed cavity 133 and moves in a direction close to and away from the second lock hole 32. The locking member 5 has a sliding portion 51 slidably disposed in the sliding groove 61. The locking member 5 also has a fixed portion 52 opposite to the second lock hole 32. The rotating linkage block 6 constitutes the movement of the locking member 5 in the fixed cavity 133. When the base 1 and the top cover 2 need to be fixed, the fixed lock core 4 rotates to drive the linkage block 6 to rotate, and then the sliding portion 51 in the sliding groove 61 slides in the sliding groove 61, thereby driving the locking member 5 to move in a direction close to the second locking hole, so that the fixed portion 52 enters the first lock hole 23 and the second lock hole 32 to form a fixation.
