Embodiment approach

[0045]Wherein, in order to avoid the leakage of the damping oil and ensure the flow of the damping oil between the chambers 13, both axial ends of the gap need to be sealed. According to an embodiment of the present invention, the first connecting member further includes a seal assembly for sealing both axial ends of the gap, and the seal assembly includes a first seal for sealing one axial end of the gap. and a second seal for sealing the other axial end of the gap.

[0046] In the above, the first seal and the second seal can adopt any structure to seal the gap, but it is better not to affect the connection between the shaft sleeve 12 and other components.

[0047] According to a preferred embodiment of the present invention, such as figure 2 and Figure 4 As shown, the first sealing member includes an annular flange 112 formed on the inner peripheral surface of the first housing 11, and the second sealing member includes a flange mounted on the first housing 11 and a sha...

Abstract

The invention relates to the technical field of refrigeration equipment, and discloses a damper, a hinge and a cabinet freezer; the damper comprises a first connector and a second connector fixedly connected with the first connector; the first connector comprises a first shell and a shaft sleeve; a cylindrical cavity is confined at the interior part of the first shell; the shaft sleeve is sleevedin the first shell and enabled to rotate relative to the first shell; a radial clearance is left between the shaft sleeve and the first shell; a first heave axially extending along the first shell isformed on the inner circumferential surface of the first shell; a second heave axially extending along the shaft sleeve is formed on the outer circumferential surface of the shaft sleeve; the first heave and the second heave divide the clearance into a plurality of cavities; damping oil is filled in the cavities; one side of each cavity is closed; and the other side of each cavity is communicatedwith the adjacent cavity through oil slots formed on the first heave and the second heave.

Description

technical field [0001] The invention relates to the technical field of refrigeration equipment, in particular to a damper, a hinge containing the damper and a freezer containing the hinge. Background technique [0002] The hinges used in existing freezers are generally hinges with ordinary springs. During the use of this type of freezer, when the user opens the door to 45-50 degrees, the door will bounce violently under the action of the spring. When the user closes the door to the maximum angle of 45-50 degrees, the door body will fall freely and close suddenly, which will generate a lot of noise and easily hurt the user's arm. In addition, the service life of the hinge is reduced. Contents of the invention [0003] The object of the present invention is to provide a damper, a hinge containing the damper and a freezer containing the hinge to realize the slow opening and closing of the door of the freezer, thereby solving the problem that the freezer is easy to shake when...
