Freezer buffer hinge with power assisting and hovering functions

Abstract

The invention provides a freezer buffer hinge with power assisting and hovering functions. The freezer buffer hinge comprises a swing arm and a base, wherein the swing arm is matched and hinged with the base through a main shaft; a buffer transmission device is arranged on the base; the buffer transmission device comprises a buffer damper, a clamping seat, a transmission sleeve and a swing shaft; the clamping seat is clamped on the base; the transmission sleeve is arranged on the buffer damper in a sliding manner; a cylinder body of the buffer damper is positioned and connected to the clamping seat; a push rod of the buffer damper is positioned and connected to the interior of the transmission sleeve; the positioning end of the transmission sleeve is clamped on the swing shaft and is connected with the swing shaft in a sliding manner; and the swing shaft is arranged at the swing end of the swing arm and is connected with the base in a sliding manner. The freezer buffer hinge is simple in structure and stable in operation, and can realize power assisting, damping and hovering effects in a limited space, so that the use quality of a product is improved.

Description

technical field [0001] The invention relates to the technical field of freezer hinges, in particular to a freezer buffer hinge with power-assisted and hovering functions. Background technique [0002] At present, freezer hinges generally use spring compression to support the strength of the door body, so as to realize the rotation and opening or closing of the freezer door body, which has the advantages of good closing performance and high rotation stability. [0003] However, existing freezer hinges have the following deficiencies in practical applications: [0004] 1) Due to the different loads of the freezer door, especially the heavy-duty freezer door, it is necessary to install a spring with a large elastic force on the hinge to support the door, resulting in a complex hinge structure and increasing the hinge volume. At the same time, when the freezer door is opened at a certain angle , Under the elastic action of the spring, it is easy to generate a large impact force...

AI Technical Summary

Problems solved by technology

[0004] 1) Due to the different loads of the freezer door, especially the heavy-duty freezer door, it is necessary to install a spring with a large elastic force on the hinge to support the door, resulting in a complex hinge structure and increasing the hinge volume. At the same time, when the freezer door is opened at a certain angle , under the elastic action of the spring, it is easy to produce a large impact force, damage the freezer and hinge, and reduce the service life of the product

[0005] 2) Traditional freezer hinges are difficult to realize the hovering of the door body, and the use effect is not good

[0006] 3) When the traditional freezer hinge has a heavy load, it requires a large external force to rotate the freezer door, which is inconvenient to operate. At the same time, after the freezer door is closed, the traditional freezer hinge has a large gap, poor closing performance, and easy Causes the accumulation of moisture, dirt, etc.
