Detailed Description

The invention is further described below with reference to the accompanying drawings.

Referring to the attached drawings 1-3, the freezer buffer hinge with the power-assisted hovering function comprises a swing arm 1 fixed on a freezer door body and a base 2 fixed on a freezer cabinet body, wherein the swing arm 1 is matched and hinged with the base 2 through a main shaft. Wherein, a buffer transmission device is arranged on the base 2. Buffer gear includes buffer damper 3, joint seat 4, transmission cover 5, swing axle 6, joint seat 4 clamps on base 2, transmission cover 5 sliding fit is on buffer damper 3, buffer damper 3's cylinder body positioning connection is on joint seat 4, and buffer damper 3's catch bar positioning connection is in transmission cover 5, the location end joint of transmission cover 5 on swing axle 6 and with 6 sliding connection of swing axle, swing axle 6 establish at swing end of swing arm 1 and with base 2 sliding connection.

Referring to fig. 1 to 3, further detailed, the transmission sleeve 5 is provided with a clamping groove 19, and the clamping groove 19 is provided with a clamping sleeve 11 for clamping with the swinging shaft 6.
