Description

Technical Field

[0001] This utility model relates to the field of freezer technology, and in particular to a counterweight device to prevent a freezer from tipping over. Background Technology

[0002] A freezer (also known as a refrigerator) is a device used to store and maintain food or other items at low temperatures. In a wide range of commercial applications, it is commonly found in restaurants, bars, food processing facilities, supermarkets, and other similar locations. Through years of technological innovation and evolution, current upright freezers, using lightweight and thin materials, can achieve both insulation and cooling effects, reducing production costs and overall weight.

[0003] Meanwhile, in order to enhance the refrigeration and insulation effect, the freezer door is usually made of double-layer explosion-proof glass and coated with low-e heat insulation radiation film, making the freezer door itself heavier than the overall weight of the freezer than the previous structure.

[0004] However, this trend in refrigerator design (lighter cabinets and reinforced doors) also brings potential safety hazards. Specifically, lighter refrigerators may tip forward or even overturn if improperly handled, such as by applying excessive force when opening or closing the door, by accidental collisions, or by children playfully pulling on them out of curiosity. Such incidents could not only damage the refrigerator itself but also potentially lead to serious accidents, posing a direct threat to personal safety. Utility Model Content

[0005] In view of this, the present invention proposes a counterweight device to prevent a freezer from tipping over. The purpose is to provide an additional counterweight component for the freezer without changing its original structure, so as to improve the stability and safety of the freezer during use.

[0006] The solution provided by this utility model includes:

[0007] A counterweight device for preventing a freezer from tipping over, the counterweight device comprising:

[0008] A counterweight support platform is provided at the bottom of the freezer to support the freezer. The center of gravity of the counterweight support platform is biased towards its first side, which is located at the rear of the bottom of the freezer.

[0009] Additional support members are provided at the bottom of the counterweight platform;

[0010] A connecting component for connecting the counterweight platform and the freezer.

[0011] As a further optional solution, the counterweight support platform is provided with multiple clearance holes.

[0012] As a further optional feature, the additional support includes casters.

[0013] As a further optional feature, the additional support includes a foot cup.

[0014] As a further optional solution, the counterweight platform includes a first counterweight plate, two second counterweight plates, a transverse connecting rod, and two longitudinal connecting rods; the transverse connecting rod is connected between the two second counterweight plates, and the longitudinal connecting rod is connected between the first counterweight plate and the second counterweight plate; the weight of the first counterweight plate is greater than the sum of the weights of the two counterweight plates; and the first counterweight plate is located at the rear of the bottom of the freezer.

[0015] As a further optional solution, the connecting assembly includes a first connecting plate, the lower end of which is connected to the first side of the counterweight support platform. The first connecting plate has a vertically arranged strip hole for bolting to the rear wall panel of the freezer.

[0016] As a further optional solution, the connecting assembly includes a second connecting plate, the lower end of which is connected to the first side of the counterweight support platform, and the upper end of the second connecting plate is formed with a hook for hooking with the mesh panel at the rear of the freezer.

[0017] Compared with the prior art, the counterweight device for preventing the freezer from tipping over in this application has at least the following advantages:

[0018] This counterweight is located at the bottom of the freezer and supports it, disregarding the original space limitations of the freezer's ground clearance. It retains the ability to be easily moved via casters and allows for easy access to the bottom of the freezer by small forklifts. This increased weight shifts the overall center of gravity of the freezer and counterweight backward and downward, significantly improving its resistance to tipping over in various usage scenarios and effectively preventing accidents caused by improper operation or accidental collisions. Furthermore, the counterweight does not affect the freezer's structure and is compatible with various models, offering high versatility. Because the counterweight is located at the bottom and does not protrude to the sides, it does not affect the freezer's aesthetics or placement flexibility, eliminating the tripping hazard or space interference that could arise from an additional protrusion, ensuring the freezer's suitability in various commercial environments.

[0026] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.

[0027] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "vertical", "horizontal", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0028] In this utility model, unless otherwise explicitly specified and limited, the terms "installation," "connection," "joining," and "fixing," etc., should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral part; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; they can refer to the internal communication of two components or the interaction between two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0029] In this utility model, unless otherwise explicitly specified and limited, "above" or "below" the second feature can mean that the first feature is in direct contact with the second feature, or that the first feature is in indirect contact through an intermediate medium. Furthermore, "above," "on top of," and "over" the second feature can mean that the first feature is directly above or diagonally above the second feature, or simply that the first feature is at a higher horizontal level than the second feature. "Below," "below," and "under" the second feature can mean that the first feature is directly below or diagonally below the second feature, or simply that the first feature is at a lower horizontal level than the second feature.

[0030] refer to Figure 1-3 This utility model provides an embodiment of a counterweight device to prevent a freezer from tipping over. The counterweight device includes a counterweight platform 1, an additional support 2, and a connecting assembly 3. The counterweight platform 1 is positioned at the bottom of the freezer 100 to support it. The center of gravity of the counterweight platform 1 is biased towards its first side 1a, which is positioned at the rear of the bottom of the freezer 100. The additional support 2 is positioned at the bottom of the counterweight platform 1. The connecting assembly 3 connects the counterweight platform 1 and the freezer 100.

[0031] Specifically, by supporting the counterweight platform 1 on the bottom of the freezer 100 and using the connecting component 3 to combine the counterweight platform 1 with the freezer 100, relying on the structural characteristic that the center of gravity of the counterweight platform 1 is biased towards the first side 1a, the overall center of gravity of the counterweight platform 1 and the freezer 100 is adjusted backward, making it less likely for the freezer 100 to tip over.

[0032] It should be noted that, to better understand the advantages of the above structure, it is necessary to understand the structural characteristics of the existing freezer 100. The bottom of the freezer 100 is usually equipped with supporting components 110 such as wheels, pads, or feet to raise the freezer 100 to a certain height from the ground. However, the space between the bottom of the freezer 100 and the ground is relatively small, which is insufficient to install a sufficient number and weight of counterweights. In particular, the counterweights should be concentrated at the rear of the freezer 100 to achieve the purpose of shifting the center of gravity to the rear. In addition, due to the lightweight design of the freezer 100, a large amount of thin materials are used. For example, the back and side walls of the freezer 100 are made of very thin metal plates. If the counterweights are installed in these positions, the metal plates cannot provide reliable support for the counterweights, which can easily lead to structural deformation or damage to the freezer 100. Furthermore, it will also cause the counterweights to protrude from the external outline of the freezer 100, affecting the placement and causing interference or tripping risks.

[0033] In this embodiment, an additional support 2 is provided at the bottom of the counterweight platform 1. This additional support 2 replaces the original support 110 on the freezer 100 for support, thereby allowing the thickness of the counterweight platform 1 to disregard the original ground clearance of the freezer 100's bottom, enabling the counterweight platform 1 to provide sufficient weight distribution. Figure 1 As shown, when the counterweight device of this embodiment is installed at the bottom of the freezer 100, the additional support 2 is used to support the freezer on the ground, while the original support 110 of the freezer 100 is lifted off the ground.

[0034] Thus, the counterweight device, positioned at the bottom of the freezer 100, supports the freezer 100, disregarding the original spatial limitations of its ground clearance. This increases the weight of the freezer 100, shifting the overall center of gravity of the freezer 100 and the counterweight device backward, significantly improving its resistance to tipping over in various usage scenarios. This effectively prevents accidents caused by improper operation or accidental collisions. Furthermore, the counterweight device does not affect the structure of the freezer 100, making it compatible with various models and highly versatile. Moreover, its placement at the bottom of the freezer 100 prevents it from protruding to the sides, thus maintaining its aesthetics and placement flexibility. It also eliminates the risk of tripping or spatial interference that could result from an additional protrusion, ensuring the freezer 100's suitability in various commercial environments.

[0035] In some embodiments, to avoid interference between the counterweight platform 1 and the existing support 110 on the freezer 100, such as Figure 1 and Figure 2 As shown, the counterweight support 1 is provided with multiple clearance holes 11. During installation, the support member 110 at the bottom of the freezer 100 is inserted into the clearance holes 11 on the counterweight support 1, so that the bottom of the freezer 100 can be stably placed on the top of the counterweight support 1. It should be noted that, in Figure 2 In the figure, the support 110 on the freezer 100 shown is a wheel. In fact, the support 110 may also be a pad, a foot cup or other support structure, but the structure of the clearance hole 11 in this embodiment is applicable.

[0036] In some embodiments, to facilitate the movement of the counterweight support 1 and to maintain the original mobility of the freezer 100, such as... Figure 2 As shown, the additional support 2 includes casters 21. Thus, even when the freezer 100 is combined with the counterweight platform 1, it remains easy to move.

[0037] In addition, to improve the placement stability of the counterweight support 1 and the freezer 100, such as Figure 2As shown, the additional support 2 includes a foot cup 22; conventionally, the foot cup 22 is height adjustable so that it can touch the ground or leave the ground. If the foot cup 22 is adjusted to leave the ground, the counterweight support 1 and the freezer 100 can be moved; if the foot cup 22 is adjusted to touch the ground, the counterweight support 1 and the freezer 100 can be prevented from moving.

[0038] In some embodiments, to achieve stable load-bearing of the counterweight support platform 1 on the freezer 100, and to achieve the purpose of adjusting the center of gravity backward, such as Figure 3 As shown, the counterweight platform 1 includes a first counterweight plate 12, two second counterweight plates 13, a transverse connecting rod 14, and two longitudinal connecting rods 15; the transverse connecting rod 14 is connected between the two second counterweight plates 13, and the longitudinal connecting rod 15 is connected between the first counterweight plate 12 and the second counterweight plate 13. The weight of the first counterweight plate 12 is greater than the sum of the weights of the two counterweight plates, and the first counterweight plate 12 is located at the rear of the bottom of the freezer 100.

[0039] Two second counterweight plates 13 are distributed at the front two corners of the bottom of the freezer 100, while the first counterweight plate 12 is arranged at the rear of the bottom of the freezer 100 to provide stable support for the freezer 100. The aforementioned auxiliary support components 2, such as the casters 21 and the feet 22, are set on the first counterweight plate 12 and the second counterweight plate 13. In addition, the two second counterweight plates 13 and the first counterweight plate 12 are connected into a whole by a horizontal connecting rod 14 and a vertical connecting rod 15. The horizontal connecting rod 14 is set along the left and right direction of the freezer 100, and the vertical connecting rod 15 is set along the front and back direction of the freezer 100. The weight on the counterweight support 1 is mainly concentrated on the first counterweight plate 12, so that the center of gravity of the counterweight support 1 is biased towards the position of the first counterweight plate 12, that is, biased towards the first side 1a.

[0040] In some embodiments, to facilitate the integration of the counterweight support 1 with the freezer 100, such as... Figure 1-3 As shown, the connecting component 3 includes a first connecting plate 31, the lower end of which is connected to the first side 1a of the counterweight support 1. The first connecting plate 31 has a vertically arranged strip hole 311, which is used to form a bolt connection with the rear wall panel of the freezer 100.

[0041] In addition, such as Figure 1 and Figure 2As shown, a conventional freezer 100 typically has a mounting chamber (not marked) for installing refrigeration components (such as compressors, condensers, etc.) located at the lower part of the freezer 100, with the opening of the mounting chamber located at the rear. A mesh panel 120 is installed at the opening for protection and to facilitate ventilation and heat dissipation. In this embodiment, the connecting assembly 3 includes a second connecting plate 32. The lower end of the second connecting plate 32 is connected to the first side 1a of the counterweight support 1, and the upper end of the second connecting plate 32 has a hook portion 321 for hooking with the mesh panel 120 at the rear of the freezer 100. Thus, the second connecting plate 32 does not need to be connected to the freezer 100 via a bolt assembly, making assembly and disassembly more convenient.

[0042] The first connecting plate 31 and the second connecting plate 32 can be either one or both, depending on the actual situation.

[0043] In the above embodiments, the descriptions of each embodiment have different focuses. For parts not described in detail in a certain embodiment, please refer to the relevant descriptions of other embodiments.

[0044] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and substitutions can be made without departing from the technical principles of the present utility model, and these improvements and substitutions should also be considered within the protection scope of the present utility model.
