Problems solved by technology

It rotates along the fixing part on the box body through the hinge structure and translates backward, so that the buckle part on the hinge structure engages with the buckle part on the door body, and then continues to rotate with the hinge structure, so that the buckle part and the buckle Locking parts, so as to realize the locking function of the cabinet body and the door body, but its structure is too complicated, and cannot effectively ensure the effective locking of the cabinet body and the door body, and it is easy to cause the hinged structure to rotate in place, and the buckle parts It only cooperates with the locking part and locks it without locking it, which will still cause the situation of lax closure and leakage of cold
[0004] At the same time, no matter the above-mentioned locks or locking devices, they do not have the function of handles. During the design, a separate handle needs to be added to the door body, and its structural integration is not perfect.

Embodiment 1

[0026] Such as Figure 1~4 As shown, in this embodiment, the refrigerator door body locking device with the handle function is fixedly installed with a mounting seat 2 on the door body 1, and a rotating shaft 3 is arranged on the mounting seat 2 to lock the handle 4. The middle part is hinged on the mounting base 2 through the rotating shaft 3. The upper end of the locking handle 4 is the grip end 5, which is used for hand-held operation when locking and loosening. The lower end is the locking end 6, and the inner side of the locking end 6 (and To the side of the cabinet body 8) there is a locking guide groove 7; at the same time, a fixing seat 9 is fixedly installed on the cabinet body 8, and a locking protrusion 10 is installed on the fixing seat 9, and the installation of the locking protrusion 10 The position should correspond to the locking guide groove 7, that is, when the locking handle 4 rotates around the rotating shaft 3 to a certain angle, the locking protrusion 10 ...

Embodiment 2

[0038] Such as Figure 5 , 6 As shown, in this embodiment, the structure of the refrigerator door locking device with handle function is basically the same as that in Embodiment 1; only the first lock ring 12 is set on the mounting base 2, and the The second locking ring 13 is arranged on the locking handle, and the first locking ring 12 and the second locking ring 13 overlap when the locking handle 4 is locked, as Figure 6 As shown, the refrigerator door locking device has the function of a lock to prevent personnel from opening it at will.

[0039] Its locking and loosening actions, door opening and closing actions are the same as those in Embodiment 1, and will not be repeated here.

[0040] The locking device for the refrigerator door body with the handle function, by rotating the locking handle, the locking guide ring at the lower end of the locking handle cooperates with the locking protrusion to lock, thereby realizing the locking of the door body and the cabinet bod...

Abstract

The invention discloses a refrigerator door body locking device with a handle function. A mounting base is fixedly mounted on a door body; a rotating shaft is arranged on the mounting base; the mounting base is hinged with the middle part of a locking handle through the rotating shaft; the upper end of the locking handle is a holding end, and the lower end of the locking handle is a locking end; a locking guide groove is arranged on the inner side of the locking end; a fixing base is fixedly mounted on the cabinet body; a locking bump is mounted on the fixing base; the fixing base locks and unlocks the locking bump and the locking guide groove, which are matched, through the rotation of the locking handle; when the locking handle rotates to a vertical state, the locking guide groove is locked with the locking bump in the matched manner; when the locking handle rotates to a certain angle, the locking guide groove and the locking bump are separated; and a locking guide ring at the lower end of the locking handle is locked with the locking bump in the matched manner by rotating the locking handle, so that the door body is tightly locked with the cabinet body. Therefore, the sealing property of the large-size refrigerated cabinet is improved. The refrigerator door body locking device provided by the invention has the advantages of simple structure, convenience in production, convenience in use and the like..

Description

technical field [0001] The invention relates to a locking device, in particular to a refrigerator door locking device which also has the function of a handle. Background technique [0002] With the advancement of science and technology, the application range of refrigeration equipment is becoming wider and wider. For example, refrigerators have become an indispensable household appliance in our daily life. Traditional freezer devices such as refrigerators all adopt the method of free closing of the door body, and the closed state of the door body is kept by the magnetic strip suction force of the sealing strip between the cabinet body and the door body, but this closing method is only suitable for smaller volumes. For small freezer installations, if the door body is large, such as the door body of a large refrigerator or cold room, the magnetic strip suction of the sealing strip must be used to close, which will easily cause the door body to open automatically, and the situa...
