Problems solved by technology

[0003] The door panel of the electric damper drives it to swing open and close through the rotating shaft. Figure 1-3 As shown, the shaft connection hole 1 on the door panel is a rectangular blind hole. When assembling with the shaft, if the fit between the shaft and the hole is too tight, it will be difficult to assemble, and if it is too loose, it will affect the product accuracy. Therefore, the machining accuracy of the shaft and the hole is required very high , while the refrigerator electric damper is originally small in size and size, the higher the processing accuracy means the processing is difficult and the cost is high

Embodiment 1

[0017] as attached figure 1 , 4 Shown is an electric damper door panel of a refrigerator. A connecting hole 1 is provided at the connecting part of the rotating shaft on the door panel, and sawtooth 2 is provided on the contact part between the connecting hole 1 and the rotating shaft, that is, the inner wall of the connecting hole 1 is provided with sawtooth 2 . The tooth height of the sawtooth 2 is 0.6mm±0.1mm, the tooth spacing is 0.4mm±0.1mm, and the tooth shape is pointed or round.

[0018] Specifically, as attached Figure 4 As shown, the serrations 2 are arranged on the upper edge of the inner wall of the connecting hole 1, arranged linearly, and are arranged on at least one upper edge of one side.

[0019] When the rotating shaft is inserted into the connecting hole, the sawtooth acts on the surface of the rotating shaft, making the plastic part of the rotating shaft easy to deform. At the same time, the sawtooth and the surface of the rotating shaft form a transiti...

Embodiment 2

[0022] The difference from Embodiment 1 is that the serrations 2 are arranged in the inner wall of the connecting hole 1 in a linear arrangement.

Embodiment 3

[0024] The difference from Embodiment 1 is that the sawtooth 2 is arranged in the inner wall of the connection hole 1 , scattered and arranged in a planar manner.

Abstract

The invention discloses an electric air door sheet of a refrigerator. A rotary shaft connection portion of the door sheet is provided with a connection hole, and the portion, in contact with a rotary shaft, of the connection hole is provided with saw teeth. The electric air door sheet has the advantages that the saw teeth are arranged in the connection hole of the rotary shaft of the door sheet, a rotary shaft plastic part is prone to deforming, the door sheet is connected with the rotary shaft in a transition matching mode, requirements for machining precision of the connection hole and the rotary shaft are reduced, assembling is facilitated and no gaps exist.

Description

technical field [0001] The invention relates to an electric damper for a refrigerator, in particular to a door panel of the electric damper. Background technique [0002] In household air-cooled refrigerators, the damper is an essential component. Refrigerators are one of the main household appliances, and their popularity rate is getting higher and higher, and the trend of intelligent refrigerator control is becoming more and more obvious. The market demand promotes the development and improvement of electric dampers. For the electric damper, it is required to be able to accurately execute the command of the electrical signal, so as to accurately control the action of the action component. [0003] The door panel of the electric damper drives it to swing open and close through the rotating shaft. Figure 1-3 As shown, the shaft connection hole 1 on the door panel is a rectangular blind hole. When assembling with the shaft, if the fit between the shaft and the hole is too t...
