The lock core assembly 1 has a first state of being locked with the first locking buckle assembly 2 so that the first fixture is connected with the second fixture, and the lock core assembly 1 also has a second state of being locked with the second locking buckle 3 so that the first fixture is connected with the third fixture. Specifically, the lock cylinder assembly 1 includes a rotatable rotary lock rod 14, and the rotation of the rotary lock rod 14 enables the lock cylinder assembly 1 to be switchable between the first locking buckle assembly 2 and the second locking buckle 3. Correspondingly, the lock rod can be matched with the first locking buckle component 2 for locking after rotating to a first preset position; when the lock rod rotates to a second preset position, the lock rod can be locked by matching with the second locking buckle 3.

In some alternative implementations, the plug assembly 1 further includes a bearing housing 11, a bearing 12, and a connecting shaft 13. The bearing housing 11 is a cylindrical structure, the bearing housing 11 and the bearing 12 are coaxially arranged, one end of the bearing housing is fixed to the bearing 12, and the other end of the bearing housing is connected with the rotary lock rod 14. And a bearing outer ring of the bearing 12 is fixed with the bearing shell 11, and a bearing inner ring is fixed with the connecting shaft 13.

The mode of opening the door is different from traditional direct pulling open, can realize opening the door and closing the door through pressing the door plant, and is convenient nimble.

To further illustrate the solution of the present invention, in the embodiment, a washing machine is taken as an example, and a method for using the clothes treatment apparatus is provided.

Assuming that the initial state is the working state of the washing machine, the second inner cylinder and the first inner cylinder of the washing machine are matched with the groove through the telescopic ball to realize the fixation on the position, the second inner cylinder and the first inner cylinder become a complete inner cylinder to work at the moment, the lock core assembly 1 connected to the door plate is matched with the first locking buckle fixed by the outer cylinder at the moment, so that the fixation of the door plate cannot be influenced by the movement of the inner cylinder, and meanwhile, the door of the washing machine cannot be opened by controlling the washing machine to be in the working state through the electric control device in the washing machine.

The washing machine stops working and enters a standby state, the door plate needs to be opened to take clothes, and the electric control device is also used for controlling the washing machine to open and close the door through external operation in the standby state. Press the door plant, the door plant drives connecting axle and bearing housing 11 and moves along axial translation, fix the rotatory locking lever atress on bearing housing 11 this moment, make rotatory locking lever can carry out a clockwise rotation on spiral guide part 222 and add the upward compound motion of vertical direction, make the spring receive the extrusion of rotatory locking lever in compression state simultaneously, the hand is according to loosening after going to the end, the spring resumes the not atress state from compression state and can make rotatory locking lever drive all parts above him and do the upward motion of vertical direction along the wall, when rotatory locking lever reachs the highest point, the locking hole 141 on the rotatory locking lever can be at return positive direction inclined plane 312 guide downward movement to the correct position and lug cooperation, simultaneously, the ball of rotatory locking lever can be blocked by barb 2224, prevent rotatory locking lever antiport. The rotatory locking lever of being connected with the door plant this moment rotates 180, with fix the second locking knot 3 cooperation at the second inner tube, the door plant just links together with the second inner tube like this, the second inner tube just can be pulled out together with the door plant, forms the axial motion that the cooperation was realized through the slide rail and on the second inner tube with the promotion muscle of promoting muscle complex recess and first inner tube. The bottom of the second inner cylinder can scrape off the clothes hung on the cylinder wall in the movement process, so that small clothes are prevented from being left in the cylinder, and meanwhile, the bottom of the second inner cylinder can be blocked by the first baffle of the first inner cylinder, so that the second inner cylinder is prevented from being pulled out of the inner cylinder by excessive force. The lock from the working state to the standby state is converted from being fixed on the outer cylinder to being fixed on the second inner cylinder.

The operation of changing the washing machine from the standby state to the working state is approximately the same as the above, the rotary lock rod connected with the door plate can be separated from the second locking buckle fixed on the second inner cylinder, and is matched with the first locking buckle fixed on the outer cylinder after rotating for 180 degrees, so that the door plate can be fixed on the outer cylinder, and meanwhile, the telescopic ball on the second inner cylinder can be matched with the ball groove (limiting hole) of the first inner cylinder, so that the second inner cylinder cannot move in the axial direction. A gap for the lock assembly to move is arranged between the front side cylinder opening of the outer cylinder and the inner cylinder, so that the position and the structure of the lock assembly cannot be damaged by the rotation of the inner cylinder.

In the washing machine, the motor part is also provided with an electromagnetic device, and the electric control device is provided with a locking function, the electromagnetic device can ensure that the inner cylinder of the washing machine has the same angle and position when starting to run and stopping running at each time, so that all parts of the lock assembly can be ensured to be correct in correspondence, and the locking device can prevent the inner cylinder from rotating to damage the door panel after the door lock is matched with the lock fixed on the second inner cylinder.
