Abstract
Description
Technical Field
[0001] This utility model relates to the field of refrigerator technology, and in particular to a drawer slide assembly for a low-temperature freezer and a low-temperature freezer containing the same. Background Technology
[0002] Because of the low internal temperature of a low-temperature refrigerator, when the refrigerator door is opened and closed, outside air enters the refrigerator and encounters the cold air inside, which will cause frost to form on the surface of items and structural components inside the refrigerator. This makes ball bearing slide rails and mechanical slide rails with small gaps unusable inside the low-temperature refrigerator.
[0003] In addition, in low-temperature refrigerators, the shelves are usually fixed to the inner wall shelves. When there are many items on the shelves, such as reagent bottles, users need to reach deep into the refrigerator to find the items they want to take out, which is very inconvenient. Utility Model Content
[0004] To address the aforementioned problems, this invention provides an advantageous drawer slide assembly for a low-temperature freezer and a low-temperature freezer incorporating the same.
[0005] Therefore, according to one aspect of the present invention, a drawer slide assembly for a low-temperature freezer is provided, characterized in that it includes a double-wing storage basket, a sheet metal left slide rail, and a sheet metal right slide rail, wherein the double-wing storage basket includes a storage basket body, a storage basket left wing, and a storage basket right wing; both the sheet metal left slide rail and the sheet metal right slide rail have a lower resting surface; the left wing and the right wing of the storage basket are respectively arranged to be slidably rested on the lower resting surface of the sheet metal left slide rail and the sheet metal right slide rail.
[0006] Furthermore, both the sheet metal left slide rail and the sheet metal right slide rail have a vertical body, an upper limit plane, and a rear stop. The vertical body, the upper limit plane, and the lower support plane form an inward-facing U-shaped groove structure.
[0007] Furthermore, the lower shelf plane has a front transition section at its front end, which is configured to bend downward at a certain angle relative to the lower shelf plane.
[0008] Furthermore, the front transition section is designed to bend downwards by approximately 10° relative to the plane of the object being placed.
[0009] Furthermore, the vertical bodies of the sheet metal left slide rail and the sheet metal right slide rail are provided with slide rail hooks on their outer surfaces to connect the sheet metal left slide rail and the sheet metal right slide rail to the front and rear shelf strips on the inner wall of the low temperature freezer.
[0010] Furthermore, there are two chute hooks, which are respectively located at the front and rear ends of the vertical body.
[0011] Furthermore, the storage basket body of the dual-wing storage basket includes the bottom of the storage basket and the storage basket enclosure.
[0012] Furthermore, the left and right wings of the storage basket are on the same horizontal plane as the bottom of the storage basket.
[0013] According to another aspect of the present invention, a low-temperature freezer comprising the above-described drawer slide assembly for a low-temperature freezer is provided.
[0014] Compared with existing technologies, this utility model has the following advantages:
[0015] 1) The double-wing storage basket is placed on the lower shelf plane of the sheet metal left slide and sheet metal right slide, and the two slide in line contact, so it will not be unable to be pulled out due to frost.
[0016] 2) Slide hooks are provided on the back of the sheet metal left slide and the sheet metal right slide, i.e. the outer side of the vertical body, so that users can adjust the position and height of the double-wing storage basket in the low-temperature freezer according to the usage.
[0017] 3) When the double-wing storage basket is pulled out along the lower shelf plane of the sheet metal left slide and the sheet metal right slide, the front end of the double-wing storage basket will droop due to gravity and the rear end will tilt up slightly. The height of the tilt of the rear end of the double-wing storage basket is limited by the upper limit plane of the sheet metal left slide and the sheet metal right slide, so that the double-wing storage basket cannot be freely removed from the sheet metal left slide and the sheet metal right slide.
[0018] 4) When the double-wing storage basket is pushed into the low-temperature freezer, the front transition part of the sheet metal left slide and sheet metal right slide has a downward bending angle structure, which can prevent the bottom of the storage basket from being scratched.
[0019] 5) The rear stops of the sheet metal left slide rail and sheet metal right slide rail serve to prevent the double-wing storage basket from touching the rear inner wall of the low-temperature freezer liner, thus avoiding damage to the liner.
[0020] These and other aspects of the present invention will be more clearly illustrated by referring to the embodiments described below. Attached Figure Description

[0028] The specific embodiments of this utility model will now be described in conjunction with the accompanying drawings.
[0029] like Figures 1 to 5 As shown, a drawer slide assembly 100 for a low-temperature freezer according to a specific embodiment of the present invention includes a double-wing storage basket 1, a sheet metal left slide rail 32, and a sheet metal right slide rail 34. The double-wing storage basket 1 includes a storage basket body 10, a left wing 12, and a right wing 14. Both the sheet metal left slide rail 32 and the sheet metal right slide rail 34 have a lower resting surface 31. The left wing 12 and the right wing 14 are respectively arranged to slide along the lower resting surface 31 of the sheet metal left slide rail 32 and the sheet metal right slide rail 34. Because of the line contact sliding, the double-wing storage basket 1 will not be unable to be pulled out due to frost.
[0030] like Figure 3 and Figure 4 As shown, in this embodiment, the sheet metal left slide groove 32 and the sheet metal right slide groove 34 also have a vertical body 33, an upper limit plane 35 and a rear stop 37, wherein the vertical body 33, the upper limit plane 35 and the lower support plane 31 form an inward-facing U-shaped groove structure.
[0031] In this embodiment, by setting the upper limit plane 35, when the double-wing storage basket 1 is pulled out along the lower shelf plane 31 of the sheet metal left slide groove 32 and sheet metal right slide groove 34, the front end of the double-wing storage basket 1 will droop due to gravity and the rear end will slightly tilt up. The height of the tilt of the rear end of the double-wing storage basket 1 can be limited by the upper limit plane 35 of the sheet metal left slide groove 32 and sheet metal right slide groove 34, so that the double-wing storage basket 1 cannot freely come out of the sheet metal left slide groove 32 and sheet metal right slide groove 34; the setting of the rear stop 37 serves to limit the double-wing storage basket 1 from hitting the rear inner wall of the low-temperature freezer liner, so as to avoid damaging the inner liner.
