Abstract:
An assisting handle and a refrigerator (100) having same, the assisting handle comprising: a handle bar (10), which is provided on the front side of a door body (101) of the refrigerator (100); a rotating shaft (20), which is pivotally connected to the handle bar (10); a guide groove (90), which is arranged in the door body (101) and penetrates the door body (101); a push rod (50), which is penetratingly provided in the guide groove (90), the distal end of the push rod (50) being close to the cabinet (102) of the refrigerator (100), and the proximal end of the push rod (50) being close to the front end of the handle bar (10); and a resistance structure (60), which is provided on one side of the push rod (50) and comprises a first tooth-like structure (61) and a second tooth-like structure (62) that mesh with each other, the first tooth-like structure (61) being combined on the push rod (50). The handle bar (10) rotates along the rotating shaft (20); the front end of the handle bar (10) abuts against the proximal end of the push rod (50), and the push rod (50) slides in the guide groove (90); the distal end of the push rod (50) abuts against the cabinet (102) of the refrigerator (100) and the push rod (50) drives the first tooth-like structure (61) to move relative to the second tooth-like structure (62). The movement of the first tooth-like structure (61) relative to the second tooth-like structure (62) is used to form a rotation resistance, to improve the comfort of opening the door, and reduce a reset noise of the handle bar (10).
