[0020] The embodiments of the present invention are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and cannot be understood as limiting the present invention.
[0021] All features disclosed in this specification, or steps in all methods or processes disclosed, except mutually exclusive features and / or steps, can be combined in any manner.
[0022] Any feature disclosed in this specification (including any additional claims, abstract and drawings), unless otherwise stated, may be replaced by other equivalent or alternative features with similar purposes. That is, unless otherwise stated, each feature is only an example of a series of equivalent or similar features.
[0023] like Figure 1 , Figure 2 , Figure 3 and Figure 4 As shown, an energy-saving ultra-low temperature refrigerator of the utility model comprises an ultra-low temperature refrigerator body 1 and an inner box 2, wherein the inner box 2 is placed inside the ultra-low temperature refrigerator body 1, and a storage cavity 10 of a columnar structure is formed inside the inner box 2, and a take-in and put-out port 3 is provided on one side surface of the inner box 2 which is open to the ultra-low temperature refrigerator body 1, and a plurality of panels 4 are installed inside the inner box 2, and a plurality of installation cavities are formed between the panels 4, and circular grooves are provided on the top surfaces of the panels 4, and a rotating plate 11 is movably installed in the circular grooves, and a plurality of containing boxes 5 are provided in the installation cavities in an annular structure, and the lower ends of the containing boxes 5 are slidably connected to the rotating plate 11.
[0024] In this embodiment, ball bearings are embedded in the center of the bottom surface of the circular groove, and shafts are installed in the inner rings of the ball bearings. The other ends of the shafts are fixedly connected to the rotating plate 11. A slide groove 12 is provided on the surface of the rotating plate 11 facing the containing box 5, and a slider is installed on the bottom surface of the containing box 5 facing the slide groove 12. The sliders are slidably set in the slide groove 12, and the cross-sections of the slider and the slide groove 12 are both trapezoidal structures.
[0025] In this embodiment, both sides of the inner box 2 are recessed to form installation grooves 7, and multiple sealed bearings are embedded and installed on the inner wall surfaces of the installation grooves 7. A rotating shaft 8 is installed in the inner ring of the sealed bearing, and a roller 9 is installed at the other end of the rotating shaft 8. The outer ring surface of the roller 9 is in contact with the bottom surface inside the ultra-low temperature refrigerator body 1, and the bottom surface of the inner box 2 is not in contact with the bottom surface inside the ultra-low temperature refrigerator body 1.
[0026] In this embodiment, slots are provided on the inner wall surfaces on both sides of the opening of the ultra-low temperature refrigerator body 1, and positioning plates 6 are provided in the openings of the slots. One end of the positioning plates 6 extends to the outside and is set in contact with the outer wall surface of the inner box 2. The other end of the positioning plates 6 is set in the slot and is installed with multiple compression springs, and the other end of the compression springs is installed on the inner wall surface of the slot.
[0027] In this embodiment, the containing boxes 5 are all arranged in a fan-shaped structure, and the containing boxes 5 are all arranged in contact with each other, so that a plurality of containing boxes can fully contact each other without affecting any containing box from being pulled out.
[0028] In this embodiment, the outer ring surface of the panel 4 is arranged to protrude from the outer ring surface of the containing box 5, so that when the containing box rotates, the outer ring of the containing box does not rub against the inner wall surface of the inner box.
[0029] In this embodiment, the height of the installation cavity matches the height of the containing box 5, so that the opening at the upper end of the containing box can be sealed by the upper panel, thereby preventing the leakage of cold air.
[0030] In the present embodiment, the outer ring surface of the containing box 5 is concave to form grooves for fingers to be inserted and the containing box 5 to be pulled out. A label is also attached to the outer ring surface of the containing box, which facilitates knowing the condition of the items inside. When it is necessary to take out the items, the fingers can be inserted into the grooves and the containing box can be pulled outward, so that the containing box moves outward along the slide groove, thereby avoiding the separation between the containing box and the rotating plate.
[0031] During installation, the inner box is placed inside the ultra-low temperature refrigerator body. The roller facilitates the pushing of the inner box. After it is moved into place, the positioning plate pops outwards through the elasticity of the compression spring. The positioning plate can position the inner box front and back, which increases stability.
[0032] After the containing box is pulled out along the access opening, the items can be directly placed in the containing box. After the containing box enters the interior of the installation cavity, the upper opening of the containing box can be sealed by the adjacent panel, and the stored items can be isolated in layers through the panel and the containing box.
[0033] When it is necessary to take out items, the containing box can be pushed, so that the rotation of the containing box drives the rotating plate to rotate along the shaft rod. The containing box at a deep position can be rotated into the taking and placing opening, and the corresponding containing box can be directly pulled out. After the corresponding containing box is pulled out, the remaining containing boxes on the same layer are still in a sealed state, which greatly reduces the exposure of cold air and achieves an energy-saving effect.
[0034] When the inner box is not needed, the positioning plate is pressed into the slot. After the positioning plate is no longer blocked, the inner box can be directly moved outward by the rollers, thereby not affecting the normal use of the ultra-low temperature refrigerator body.
[0035] The above is only a specific implementation of the utility model, but the protection scope of the utility model is not limited thereto. Any changes or substitutions that are not conceived through creative work should be included in the protection scope of the utility model. Therefore, the protection scope of the utility model should be based on the protection scope defined in the claims.
