[0006] A first magnetic switch and a second magnetic switch are fixedly connected to the lower end cover assembly, and the first magnetic switch and the second magnetic switch are connected with a control system and a display screen outside;

[0007] The hinge assembly comprises a hinge and a ratchet wheel welded together with the hinge, the hinge is formed with a shaft installed in the shaft hole, and the ratchet wheel is installed in the recessed part.

[0008] Further, the cross section of the recessed part is circular.

[0009] Further, the cross section of the platform part is circular.

[0010] Further, the hinge comprises a flat plate part and an extension part perpendicular to the flat plate part, a plurality of screw holes are formed on the flat plate part to install the hinge assembly on the refrigerator body.

[0011] Further, the shaft is formed on the extension part.

[0012] Further, the ratchet wheel is sleeved on the outer side of the shaft.

[0013] Further, the pawl and the ratchet wheel are engaged together.

[0014] The refrigerator door opening and closing automatic stopping device has the advantages that the door body will not be suddenly closed when the user places or takes out the goods in the refrigerator, the use is convenient, and the design is more humanized. BRIEF DESCRIPTION OF DRAWINGS

[0021] The application will be further described below in combination with the drawings.

[0022] The refrigerator door opening and closing automatic stopping device comprises a lower end cover assembly 3 and a hinge assembly 1 installed together with the lower end cover assembly 3, wherein an axle hole 30 is formed on the surface of the lower end cover assembly 3 where the hinge assembly 1 is installed, a recessed part 31 is recessed on the surface of the lower end cover assembly 3 where the hinge assembly 1 is installed and at a distance from the axle hole 30, and the cross section of the recessed part 31 is circular. The distance between the axle hole 30 and the recessed part 31 is a platform part 32, and the cross section of the platform part 32 is also circular. A pawl fixing block 4 is integrally formed on the platform part 32, and a pawl 6 is connected to the pawl fixing block 4 through a bearing 8.

[0023] A first magnetic sensitive switch 5 and a second magnetic sensitive switch 7 are fixedly connected to the lower end cover assembly 3. The first magnetic sensitive switch 5 and the second magnetic sensitive switch 7 are externally connected to a control system and a display screen.

[0024] The hinge assembly 1 comprises a hinge 1 and a ratchet wheel 2 welded together with the hinge 1, the hinge 1 comprises a flat plate part 10 and an extension part 11 perpendicular to the flat plate part 10, a plurality of screw holes 12 are formed at intervals on the flat plate part 10 to install the hinge assembly 1 on the refrigerator body. An axle 13 is formed on the extension part 11.

[0025] In the automatic stopping device for refrigerator door, when the hinge assembly 1 and the lower end cover assembly 3 are installed together, the shaft 12 is arranged in the shaft hole 30, and the ratchet wheel 2 is arranged in the recess 31, and the pawl 8 and the ratchet wheel 2 can be engaged or disengaged.

[0026] The working principle of the automatic stopping device for refrigerator door is as follows:

[0027] The display screen arranged on the door body outputs the working command of the first magnetic switch 5 and the second magnetic switch 7, and when the door body is closed and opened, the second magnetic switch 7 works to attract the pawl 6 into the ratchet wheel 2 to stop the door body.

[0028] When the door body needs to be opened and closed, the second magnetic switch 7 is disabled, and the first magnetic switch 5 works, and the pawl 6 rotates through the bearing 8 to disengage the ratchet wheel 2, so that the door body can rotate freely.

[0029] When the user needs to open the refrigerator, the second magnetic switch 7 is used to insert the pawl into the ratchet wheel, so that the door body will not automatically close after being opened, and when the door needs to be closed, the first magnetic switch 5 is used to disengage the pawl from the ratchet wheel, so that the door body is closed.

[0030] The above is only the preferred embodiment of the present application, and it should be pointed out that for ordinary skilled in the art, without departing from the principles of the present application, a number of improvements can also be made, and these improvements should be considered as the protection scope of the present application.
