CONTENT OF THE UTILITY MODEL

[0004] The utility model solves the technical problem that provides a door lock assembly of a safe with simplified overall structure and reduced noise.

[0005] The technical solution of the utility model is as follows: a door lock assembly of a safe, including support and lock piece, motor and elastic reset member arranged on the support, the lock piece is equipped with lock tongue and is slidably arranged on the support, to switch the lock tongue between locking position and unlocking position, the output shaft of the motor is equipped with rotating disc that rotates synchronously, the end face of the rotating disc is equipped with eccentric column, the lock piece is equipped with guide groove that connects the eccentric column, the elastic reset member is arranged on one side of the lock piece, to provide the lock tongue of the lock piece with the force in the direction of locking position, when the motor is driven to rotate the eccentric column, one side of the guide groove is always abutted on the eccentric column, and the lock piece slides.

[0006] The working principle of the door lock assembly of the utility model safe is as follows:

[0007] ​In the example of locking by sliding the lock piece to the right and unlocking by sliding the lock piece to the left, the elastic reset member provides a rightward force to the lock piece; in the unlocking process, the eccentric column swings to the left, and the force of the elastic reset member is rightward, the directions of the two are just opposite, the eccentric column will overcome the force of the elastic reset member to press the left side of the guide groove, so that the guide groove moves to the left with the eccentric column, and the lock piece slides to the left to unlock the lock tongue; in the locking process, the eccentric column swings to the right, and the direction of the force of the elastic reset member is the same, the elastic reset member drives the left side of the guide groove to press the eccentric column, and moves to the right with the eccentric column, and the lock piece slides to the right to lock the lock tongue; therefore, in the unlocking process or the locking process, the left side of the guide groove is always abutted on the eccentric column, so that the guide groove can move leftward and rightward with the eccentric column.

[0008] After the above structure is adopted, the safe has the following advantages:

[0038] ​The width and length of the guide groove 8 are greater than the diameter of the eccentric column 7. This arrangement enables the eccentric column 7 to better cooperate with the guide groove 8 when rotating, and the movement is smoother and less likely to interfere and collide, and the noise is smaller. In addition, this arrangement also enables the lock piece 2 and the eccentric column 7 to have a movable space, which is beneficial to the realization of the subsequent manual scheme.

Figure 4 When unlocking is needed, the motor 3 can be started to perform electric operation, or the knob 10 can be rotated to perform manual operation. When electric unlocking is performed, as shown in FIG. 2, the motor 3 drives the eccentric column 7 to swing to the right. The eccentric column 7 presses the right side of the guide groove 8 to the right, so that the guide groove 8 moves to the right together with the eccentric column 7, and then drives the lock blade 2 to slide to the right. The lock tongue 5 slides to the unlocking position and is separated from the clamping groove 20 of the lock cylinder 19. When the safe needs to be locked again after electric unlocking, the motor 3 drives the eccentric column 7 to swing to the left. The right side of the guide groove 8 is still pressed against the eccentric column 7 under the action of the elastic reset member 4, so that the guide groove 8 moves to the left together with the eccentric column 7, and then drives the lock blade 2 to slide to the left. The lock tongue 5 slides to the locking position and is clamped into the clamping groove 20 of the lock cylinder 19. Figure 5 When manual unlocking is performed, as shown in FIG. 3, the connecting rod 18 is rotated to swing the knob 10 to the right. The knob 10 pushes the lock blade 2 to slide to the right through the abutting part 11. The lock tongue 5 slides to the unlocking position and is separated from the clamping groove 20 of the lock cylinder 19. When the safe needs to be locked again after manual unlocking, the connecting rod 18 is released. At this time, the lock blade 2 slides to the left under the action of the elastic reset member 4. The lock tongue 5 slides to the locking position and is clamped into the clamping groove 20 of the lock cylinder 19.
