A reinforced and weight-reducing freezer base

Abstract

A reinforced, weight-reducing freezer base frame includes an annular outer frame with multiple support beams. The two ends of each support beam are connected to opposite sides of the annular outer frame. The key feature is that the annular outer frame and / or support beams are partially or entirely sheet-like, and the annular outer frame and / or support beams have integrally stamped or roll-formed reinforcing protrusions. The sheet-like structure of the annular outer frame and / or support beams, along with the integrally stamped or roll-formed reinforcing protrusions, significantly improves the load-bearing strength of the base frame, thereby reducing the thickness of the annular outer frame and / or support beams, reducing material usage, and lowering costs. Making the annular outer frame and / or support beams sheet-like reduces the overall thickness of the base frame, thus minimizing the space occupied in the freezer and meeting national standards.

Description

[Technical Field] This utility model relates to a freezer base frame. [Background Technology] Refrigerated display shelves are installed inside refrigerated display cases to hold goods (beverages, etc.). To facilitate placement, multiple slides are typically installed on the shelves, with goods arranged from front to back along the slides (front refers to the side closest to the door). Because the goods themselves are relatively heavy, the base frame needs to withstand a significant weight, thus requiring considerable strength. Currently, some display shelves on the market, such as the one with patent number 202110246025.X (named "Multifunctional Self-Weighting Pulley Shelf"), have a base frame composed of a ring-shaped frame and crossbeams. To increase load-bearing capacity, both the frame and crossbeams need to be designed to be relatively thick, which not only makes the shelf itself heavier but also wastes materials.

Detailed Implementation Methods

[0036] Example 2, as Figures 5 to 6 As shown, the difference from Embodiment 1 is that the annular outer frame 1 is also provided with reinforcing protrusions 3. Specifically, the reinforcing protrusions 3 of the annular outer frame 1 are formed by roll forming and extend along the annular direction of the annular outer frame 1. The reinforcing protrusions 3 are also annular in the middle of the annular outer frame 1. In this embodiment, the reinforcing protrusions 3 on the annular outer frame 1 and the reinforcing protrusions 3 on the longitudinal beam 21 are triangular. The reinforcing protrusions 3 of the annular outer frame 1 can face inward or outward. In this embodiment, they face outward. The annular outer frame 1 is sheet-like and can be made of steel plate. Both the annular outer frame 1 and the longitudinal beam 21 use reinforcing protrusions 3, which can further reduce the thickness of the base frame, reduce material usage, and reduce the weight of the base frame.

[0037] Example 3, as Figures 7 to 9 As shown, the difference from Embodiment 2 is that the support beam 2 also includes a crossbeam 22. Specifically, the support beam 2 further includes a crossbeam 22 with its two ends connected to the bottom of the left and right sides of the annular outer frame 1, respectively. Thus, the support beam 2 consists of a crossbeam 22 and a longitudinal beam 21, which intersect. To prevent interference, a first groove 23 is provided below the crossbeam 21 at the intersection of the crossbeam 22 and the longitudinal beam 21. The first groove 23 is formed by stamping. In this embodiment, the reinforcing protrusions 3 on the annular outer frame 1, the crossbeam 22, and the longitudinal beam 21 are all arc-shaped, with the reinforcing protrusions 3 of the annular outer frame 1 facing outwards. The crossbeam 22 is sheet-like and can be made of steel plate. The crossbeam 22 can support the longitudinal beam 21, thereby improving the overall load-bearing capacity and bending resistance.

[0038] Example 4, as Figure 10 and Figure 11 As shown, the difference from Embodiment 1 is that the structure of the longitudinal beam 21 is different. Specifically, the two ends of the longitudinal beam 21 are respectively provided with steps 26 that press against the bottom of the front and rear sides of the annular outer frame 1. The longitudinal beam 21 is higher than the steps 26, causing the longitudinal beam 21 to protrude into the support groove 10. The steps 26 are downward relative to the longitudinal beam 21. The steps 26 are welded horizontally against the bottom of the front and rear sides of the annular outer frame 1.

[0039] Example 5, such as Figure 12 and Figure 13 As shown, the difference from Embodiment 1 is that the annular outer frame 1 is provided with a solid strip beam 27 with its two ends connected to the bottom of the front side and the rear side of the annular outer frame 1 respectively. The solid strip beam 27 is arranged parallel to and spaced apart from the longitudinal beam 21. The solid strip beam 27 can be square strip.

[0040] Example 6, as Figure 14 and Figure 15As shown, the difference from Embodiment 1 is that the base frame in this embodiment is not embedded; that is, the guide plate is installed on the upper end of the annular outer frame 1. Specifically, the support beam 2 includes multiple parallel crossbeams 22, each connected at both ends to the left and right sides of the inner side of the annular outer frame 1. The upper ends of the crossbeams 22 are flush with the upper end of the annular outer frame 1. The upper surface of the support beam 2 has multiple parallel support rods 4 perpendicular to the crossbeams 22 for supporting the slide. The guide plate is fixedly installed on the support rods 4. The support rods 4 are arranged longitudinally, with their two ends above the front and rear sides of the annular outer frame 1, and the middle of the support rods 4 is supported on the crossbeams 22. The support beam 2 also includes longitudinal beams 21, each connected at both ends to the front and rear sides of the inner side of the annular outer frame 1, which support the crossbeams 22. Due to the reinforcing protrusions 3, the support beam 2 can be sheet-like, reducing its thickness. Thus, the total height of the annular outer frame 1, the support beam 2, and the support rods 4 is less than or equal to 8mm, achieving an ultra-thin design. The front end face of the longitudinal beam 21 is flush with the front end face of the annular outer frame 1, and the rear end face of the longitudinal beam 21 is flush with the front end face of the annular outer frame 1, that is, the length of the longitudinal beam 21 is the same as the front and rear dimensions of the annular outer frame 1.

[0041] Example 7, as Figure 16 As shown, the difference from embodiments four and five is that the annular outer frame 1 is also provided with reinforcing protrusions 3.

[0042] Example 8, as Figure 17 and 18 As shown, the difference from Embodiment Six is ​​that the reinforcing protrusion 3 of the crossbeam 22 faces forward, and the upper and lower end faces of the crossbeam 22 are flush with the upper and lower end faces of the annular outer frame 1, respectively. A second groove 24 is provided at the intersection of the longitudinal beam 21 and the crossbeam 22, located below the longitudinal beam 21. Both ends of the longitudinal beam 21 are provided with downwardly bent sections 25, and the two bent sections 25 are respectively connected to the bottom of the front and rear sides of the annular outer frame 1.

[0043] Example 9, as Figures 19 to 21 As shown, the difference from Embodiment 5 is that a rear baffle 12 is provided on the rear side of the annular outer frame 1. The rear baffle 12 can block materials. The rear baffle 12 is a flat rod and extends to the left and right directions of the annular outer frame 1. The longitudinal beam 21, the cross beam 22, the reinforcing protrusion 3 on the annular outer frame 1 and the reinforcing protrusion 3 on the longitudinal beam 21 are triangular. The reinforcing protrusion 3 of the cross beam 22 faces the front side of the annular outer frame 1, and the reinforcing protrusion 3 of the longitudinal beam 21 faces downward.

[0044] Example 9, as Figures 22 to 24 As shown, the difference from Embodiment 5 is that the reinforcing protrusions 3 on the longitudinal beam 21 and the transverse beam 22 are both facing downwards.

[0045] Example 10, as follows Figure 25As shown, the difference from Embodiment 5 is that the annular outer frame 1 is provided with multiple solid strip beams 27, one end of which is connected to the front side of the annular outer frame 1 or the bottom of the crossbeam 22, and the other end of which is connected to the rear side of the annular outer frame 1 or the bottom of the crossbeam 22. There are two solid strip beams 27. The front end of one solid strip beam 27 is connected to the front side of the annular outer frame 1, and the other end is connected to one of the crossbeams 22. The rear end of the other solid strip beam 27 is connected to the rear side of the annular outer frame 1, and the other end is connected to one of the crossbeams 22. The solid strip beams 27 support the crossbeams 22.

[0046] Example 11, as follows Figure 26 and 27 As shown, the difference from Embodiment 1 is that, for ease of installation, mounting plates are provided on the inner wall of the freezer, and vertically adjustable positioning buckles are set on the mounting plates. Two mounting plates are respectively provided on the left and right side walls of the freezer. Two positioning protrusions 28 are respectively provided on the longitudinal beams 21 near the left and right sides of the annular outer frame 1, which correspond one-to-one with the locking buckles and can abut against one side of the locking buckles. That is, positioning protrusions 28 are provided on the leftmost and rightmost longitudinal beams 21. The positioning protrusion 28 on the left extends to the left side of the annular outer frame 1, and the positioning protrusion 28 on the right extends to the right side of the annular outer frame 1. The two locking buckles are inside or outside the two positioning protrusions 28, and the area between the two positioning protrusions 28 is the inner side. After the positioning protrusions 28 and the locking buckles abut against each other, the annular outer frame 1 cannot move longitudinally. In this embodiment, the two locking buckles are inside the two positioning protrusions 28. In this way, after the shelf is installed, the shelf can be positioned by the two positioning protrusions 28.

[0047] Example 12, as Figure 28 and 29 As shown, a reinforced and weight-reducing refrigerator base frame includes an annular outer frame 1. Multiple support beams 2 are provided on the annular outer frame 1. The two ends of the support beams 2 are respectively connected to the two opposite sides of the annular outer frame 1. The support beams 2 are plate-shaped and include multiple parallel longitudinal beams 21 with their two ends respectively connected to the bottom of the front and rear sides of the annular outer frame 1. The longitudinal beams and the annular outer frame 1 form a support groove 10 for the guide plate to be installed. The guide plate is installed on the base frame in a sinking manner, which is equivalent to embedded installation. The guide plate is longitudinally supported on the longitudinal beams 21, and the materials are placed on the guide plate. The difference from Embodiment 1 lies in the structure of the reinforcement of the support beam 2. Specifically, the support beam 2 has a bent edge 29 on at least one side along its length. In this embodiment, both sides have bent edges 29. The bent edges 29 extend upward and along the length of the support beam 2. The bent edges 29 are on the left and right sides of the longitudinal beam 21. The two bent edges 29 are inclined and arranged in a V-shape. By bending on both sides, the overall strength can be improved. The two bent edges 29 are inclined and open outward, increasing the support area, making the installation and support stable, and reducing the overall weight of the shelf.

[0048] Example 13, as Figure 30 and 31 as shown in the figure, the difference from the twelfth embodiment is that in this embodiment, the support beam 2 is only provided with a bent edge 29 on one side, the bent edge 29 extends upward, the support beam 2 is in an inverted L shape, and the single-side bending enables rapid molding, convenient installation, and can reduce the weight of the whole shelf layer.

The bent edges 29 are provided with notches at both ends of the support beam 2, the notches are pressed against the annular groove 11, so that the support beam 2 is convenient to install. The annular outer frame 1 is not easy to deform, the bending resistance is improved, and meanwhile the weight of the annular outer frame 1 can be reduced, so that the whole structure is more lightweight and thinner.

[0051] The sixteenth embodiment, as shown in Figure 36 and 37 the figure, the difference from the twelfth embodiment is that the bottom frame of this embodiment is non-embedded, that is, the sliding guide plate is installed on the upper end of the annular outer frame 1. The support beam 2 includes a plurality of parallel cross beams 22 whose two ends are respectively connected to the inner left side and right side of the annular outer frame 1, the upper end of the cross beam 22 is flush with the upper end of the annular outer frame 1, and the upper end surface of the support beam 2 is provided with a plurality of parallel support rods 4 which are perpendicular to the cross beam 22 and used for supporting the slide rails.

The annular outer frame 1 is provided with a solid strip-shaped beam 27 with one end connected to the bottom of the front side of the annular outer frame 1 and the other end connected to the bottom of the rear side of the annular outer frame 1. The solid strip-shaped beam 27 supports the cross beam 22, and the cross beam 22 is pressed against the middle part of the solid strip-shaped beam 27. The total height of the annular outer frame 1, the support beam 2 and the support rod 4 is less than or equal to 8mm. The support beam 2 is in a sheet shape, reinforced by the bent edges 29 to reduce the thickness, so that the total height of the annular outer frame 1, the support beam 2 and the support rod 4 is less than or equal to 8mm, achieving an ultra-thin design.

[0052] The seventeenth embodiment, as shown in Figure 38 and 39 as shown, the difference from the sixteenth embodiment lies in that the annular outer frame 1 is sheet-shaped, the cross section of the annular outer frame 1 is an inverted "L" shape, and the bending edge 29 on one side makes the cross beam 22 assume an inverted "L" shape. Both the annular outer frame 1 and the support beam 2 can reduce the weight, making the entire shelf thinner and lighter, simple to manufacture, and low in production cost.

[0055] The twentieth embodiment, as Figure 42 shown, the difference from the eighteenth embodiment lies in that the cross beam 22 is a "π"-shaped block, and the annular outer frame 1 is a solid frame instead of a sheet shape.
