Description

Technical Field

[0001] The utility model relates to the technical field of refrigerators, in particular to a corner protection frame for refrigerators. Background Art

[0002] A freezer, also called a refrigerator, is a device that preserves food and other items at low temperatures. There are two types of freezers: home and commercial. Commercial freezers are used in restaurants, bars, food processing, and supermarkets. The basic function of a freezer is to refrigerate and keep the inside of the freezer at a suitable low temperature. The refrigeration system generally consists of four basic components: a compressor, a condenser, a capillary tube or a thermal expansion valve, and an evaporator.

[0003] During transportation, refrigerators use foam as a buffer to protect them. However, refrigerators cannot be stacked in large quantities without foam. Different styles of refrigerators require the manufacture of multiple molds, which will be restricted during centralized transportation. Direct placement will damage the edges and corners of the refrigerators. Therefore, a corner protection rack for refrigerators is proposed. Utility Model Content

There are eight groups of wrapping angles 1, which are respectively located at eight vertex positions of the device. The wrapping angle 1 is composed of a bottom plate 101 and a storage plate 102. The threaded sleeve 2 is fixedly connected to the lower surface of the bottom plate 101 at the lower end, the linkage frame 8 is fixedly connected to the bottom plate 101, and the surface of the bottom plate 101 is fixedly connected to the storage plate 102. The storage plate 102 is a hollow shell with a folded angle. The telescopic plate 5 slides on the inner side of the storage plate 102. The wrapping angle 1 can wrap and protect the eight corners of the square refrigerator.

[0024] A double-axis motor 6 is fixedly connected to the outer surface of the telescopic plate 5, and the upper and lower output ends of the double-axis motor 6 are fixedly connected to a telescopic threaded rod 7. The outer surface of the telescopic threaded rod 7 is threadedly connected to a linkage frame 8. The linkage frame 8 has an "N" shape. Threaded holes are opened at one end of the two sets of linkage frames 8 that are close to each other. The telescopic threaded rod 7 passes through and engages with the threaded holes. The linkage frame 8 is pulled by the telescopic threaded rod 7 to determine the distance between the upper and lower wrapping angles 1, and can be suitable for refrigerators of different heights.

[0025] The linkage frame 8 is fixedly connected to the wrapping angle 1, and a sliding rod 9 is fixedly connected to the side of the wrapping angle 1. The end of the sliding rod 9 away from the wrapping angle 1 is fixedly connected to a positioning block 10, and electric telescopic rods 11 are fixedly connected on both sides of the positioning block 10. The free end of the electric telescopic rod 11 is fixedly connected to the wrapping angle 1, and the sliding rod 9 is on both sides of the electric telescopic rod 11. The upper surface of the positioning block 10 is rotatably connected with a linkage gear 12, and the outer peripheral surface of the linkage gear 12 is meshed with a rack plate 13. The rack plate 13 has an "L" shape. Two rack plates 13 are grouped together and are symmetrical around the center of the linkage gear 12. The rack plate 13 is provided with teeth on the side close to the linkage gear 12. The rack plate 13 can make the wrapping angles 1 on both sides approach synchronously to prevent the wrapping angle 1 from being unable to clamp the edges.

[0026] One end of the rack plate 13 away from the positioning block 10 is fixedly connected to the wrapping angle 1, and a support shell 14 is slidably connected to the outer side of the rack plate 13.

The gear column 17 meshes with the upper surface of the force plate 16, and a hexagonal groove is provided on the end face of the gear column 17. The gear column 17 can slightly adjust the distance between the two longitudinal wrapping angles 1, so as to facilitate the alignment of the wrapping angle 1 with the refrigerator.

[0028] Working principle: When in use, first place the device on the outside of the refrigerator, rotate the foot cup 4, adjust the height of the foot cup 4 and the threaded sleeve 2, and slide the wrapping plate 15 on the surface of the force plate 16 to determine the position by rotating the tooth column 17. The connecting rod 3 is pushed and retracted, and the two longitudinal groups of wrapping angles 1 are close to each other, and the wrapping angles 1 are aligned with the edges and corners of the refrigerator. By starting the electric telescopic rod 11, the wrapping angles 1 on both sides of the lateral side are pulled close to each other, and the sliding rod 9 is driven to retract. When the wrapping angles 1 are close, the rack plate 13 is pushed. When the rack plate 13 moves, the linkage gear 12 is pushed, so that the wrapping angles 1 on both sides are evenly close to the refrigerator and clamped. By starting the dual-axis motor 6 to drive the telescopic threaded rod 7, the upper and lower linkage frames 8 are close to each other, and the upper and lower groups of wrapping angles 1 are close to the telescopic plate 5 and wrapped on the inside to clamp the refrigerator up and down.
