Abstract
Description
Technical Field
[0001] The utility model relates to the technical field of refrigerator production, in particular to a refrigerator freezing door frame assembly. Background Art
[0002] Refrigerators are one of the indispensable household appliances in modern families, mainly used to store food and keep it fresh and safe. The sealing performance of refrigerator doors directly affects the insulation effect and energy consumption of refrigerators.
[0003] Currently, refrigerator freezer door frame assemblies on the market generally use a fixed sealing strip design. This design provides a good seal when the door is closed. However, to ensure an adequate seal, the sealing strip is also thick. As a result, the sealing strip near the door connection is prone to friction with the refrigerator body during the door opening and closing process, causing noise. Long-term friction can also cause the sealing strip to wear, affecting the refrigerator's sealing performance and service life. Utility Model Content
[0004] The purpose of this section is to summarize some aspects of the embodiments of the present invention and briefly introduce some preferred embodiments. Some simplifications or omissions may be made in this section and in the abstract and title of the utility model to avoid obscuring the purpose of this section, the abstract and the title of the utility model, and such simplifications or omissions shall not be used to limit the scope of the present invention.
[0005] In view of the above problems existing in the existing refrigerator freezer door frame assembly, the present utility model is proposed.
[0006] Therefore, the purpose of this utility model is to provide a refrigerator freezer door frame assembly that is suitable for resolving the problem of thick sealing strips, which easily rub against the refrigerator body near the door connection during door opening and closing, causing noise.

[0026] Example
[0027] Reference Figure 1-Figure 4 , is an embodiment of the present utility model, which provides a refrigerator freezer door frame assembly, comprising:
[0028] The support unit 100 includes an upper support plate 101 and a lower support plate 102, and a connector 103 mounted on the refrigerator. A vertical plate 104 is symmetrically arranged between the upper support plate 101 and the lower support plate 102. A rotating shaft 105 is rotatably connected between the upper support plate 101 and the lower support plate 102. The top end of the rotating shaft 105 passes through the upper support plate 101 and extends above the upper support plate 101. The top end of the rotating shaft 105 passes through the lower support plate 102 and extends below the lower support plate 102. Two connectors 103 are provided.
[0029] The noise reduction unit 200 includes a symmetrically arranged deflection rod 201, and the two deflection rods 201 are fixedly installed on the upper support plate 101 and the lower support plate 102 respectively. A pulley 202 is movably installed on the end of the deflection rod 201 away from the vertical plate 104. The angle between the deflection rod 201 and the upper support plate 101 is an obtuse angle. A slide groove 203 begins to be provided on the connecting member 103, and the rotating shaft 105 is located inside the slide groove 203. The noise reduction unit 200 also includes a reset component for resetting the rotating shaft 105.
[0030] In another embodiment, the reset assembly includes a fixed rod 204, two of which are provided, one end of the fixed rod 204 is fixedly connected to a baffle 205, a through hole 206 is penetrated through the baffle 205, a push rod 207 is provided inside the through hole 206, the outer surface of the push rod 207 is in contact with the inner side surface of the through hole 206, one end of the push rod 207 is fixedly connected to a push plate 208, the push plate 208 is an arc-shaped plate, the push plate 208 is bent in the direction close to the baffle 205, a spring 209 is sleeved on the push rod 207, the spring 209 is located between the baffle 205 and the push plate 208, and the other end of the push rod 207 is fixedly connected to a limiting block 210.
[0031] In another embodiment, a cam 211 is fixedly connected to the rotating shaft 105 , and the cam 211 is in contact with the push plate 208 .
[0032] In another embodiment, the two connecting members 103 are located between the two fixing rods 204 , the push rod 207 has a square cross-section, and the through hole 206 has a square cross-section.
[0033] In another embodiment, the support unit 100 further includes an inner lining plate 106 and an outer lining plate 107, both of which are welded to the vertical plate 104, the upper support plate 101, and the lower support plate 102. A slot 108 is defined on the side of the inner lining plate 106 away from the vertical plate 104, and the slot 108 is used to install a sealing strip. The slot 108 is defined on the inner lining plate 106 for installing a sealing strip to ensure a good sealing effect.
[0034] In another embodiment, the connector 103 is L-shaped, and a mounting screw hole 109 is provided on a side of the connector 103 away from the slide 203. The connector 103 is fixed to the refrigerator through the mounting screw hole 109, ensuring that the slide 203 matches the position of the shaft 105.
[0035] In another embodiment, in order to increase the stability of the rotating shaft 105 , a horizontal plate that fits with the connecting member 103 may be provided on the rotating shaft 105 .
[0036] During use, when the user manually opens the door, since the pulley 202 has already contacted the refrigerator cabinet and the angle between the deflection rod 201 and the upper support plate 101 is an obtuse angle, the rotating shaft 105 slides in the slide groove 203 to the side away from the refrigerator cabinet and rotates on its own, thereby moving the refrigerator freezer door away from the cabinet, and the sealing strip no longer contacts the cabinet, thereby avoiding friction with the refrigerator cabinet to generate noise. When the rotating shaft 105 rotates, the cam 211 rotates accordingly, thereby changing the distance between the rotating shaft 105 and the baffle 205, so that the thrust applied by the spring 209 to the rotating shaft 105 is reduced.
[0037] When the user closes the door, the shaft 105 rotates in the opposite direction, and the cam 211 gradually approaches the push plate 208 until the push plate 208 (and the cam 211) are pushed back to the initial position. At this time, the spring 209 continues to apply thrust to the cam 211 and the shaft 105, and the sealing strip fits tightly against the refrigerator body.
