[0049] Reference Figures 1-7 The utility model discloses an anti-tilting and falling counterweight structure of refrigerator, the lower portion of refrigerator 1 is equipped with the installation cavity 11 for installing refrigeration component, the installation cavity 11 has the opening in the rear of refrigerator 1, and the bottom of refrigerator 1 is equipped with sheet metal support strip 12;Additional counterweight assembly 2 is equipped on refrigerator 1, and additional counterweight assembly 2 includes connecting frame 21 and a plurality of counterweight blocks 22, connecting frame 21 is connected to sheet metal support strip 12, and counterweight block 22 is arranged on connecting frame 21, and a plurality of counterweight blocks 22 are located at the bottom of refrigerator 1 or / and in the installation cavity 11.

[0050] Among them, the embodiment adds additional counterweight assembly 2 on refrigerator 1, increases the weight of refrigerator 1 as a whole, makes its gravity center move back, significantly improves its anti-tilting and falling ability in various use scenarios, effectively prevents refrigerator 1 from tilting and falling due to improper operation or accidental collision.

[0051] It should be noted that, in order to facilitate understanding of the advantages of the above structure, the refrigerator 1 of model #316 of Meilishuo Group Co., Ltd. is described; the bottom of the refrigerator 1 is usually provided with moving wheels or pads, so that the refrigerator 1 is a certain height from the ground, however, the space of the refrigerator 1 from the ground is relatively small, and it is not enough to install a large number of counterweights 22, especially the counterweights 22 should be concentrated at the rear of the refrigerator 1, so as to achieve the purpose of moving the center of gravity backward; in addition, the back and side walls of the refrigerator 1 are made of very thin metal plates, if the counterweights 22 are installed at these positions, the metal plates cannot reliably support the counterweights 22, which can easily cause the structure of the refrigerator 1 to deform or be damaged; and it will also cause the counterweights 22 to protrude from the external contour of the refrigerator 1, which will affect the placement position and cause tripping risk.

[0052] In the embodiment, the installation cavity 11 and the metal support strip 12 of the original structure of the refrigerator 1 are ingeniously utilized, and the metal support strip 12 is used to stably support relatively heavy refrigeration components (such as a compressor, a condenser, etc.) in the installation cavity 11, so the metal support strip 12 has relatively high structural strength. In the embodiment, the counterweight 22 is combined with the metal support strip 12 through the connecting frame 21, so as to fully utilize the structural strength of the metal support strip 12 itself, and to stably support the counterweight 22; in addition, as shown in Figure 1 the space at the bottom of the refrigerator 1 and the space in the installation cavity 11 are utilized to accommodate sufficient counterweights 22, so as to achieve the purpose of sufficient counterweighting, and to avoid the counterweights 22 from exceeding the external contour of the refrigerator 1; the position of the counterweight 22 in the installation cavity 11 is close to the opening, which does not affect the arrangement of the original refrigeration components in the installation cavity 11.

[0053] In some embodiments, as shown in Figures 3-6 the connecting frame 21 includes a plurality of mounting clamps 211, the mounting clamp 211 includes a first clamp plate 2111 and a second clamp plate 2112 distributed in an up-down manner, a connecting plate 2113 is arranged between the first clamp plate 2111 and the second clamp plate 2112, and the first clamp plate 2111 and the second clamp plate 2112 are clamped on the upper and lower sides of the metal support strip 12 respectively; wherein the first clamp plate 2111 and the second clamp plate 2112 can be elastically contracted.

[0054] The counterweight 22 includes a first counterweight 22a, a second counterweight 22b, and a third counterweight 22c;

[0055] The first counterweight 22a is detachably arranged on the second clamp plate 2112, and the first counterweight 22a is clamped on the bottom of the metal support strip 12 by the second clamp plate 2112;

[0057] The third counterweight 22c is arranged on the first clamping plate 2111, and the third counterweight 22c is vertically distributed with the second counterweight 22b. Wherein, the third counterweight 22c is provided with a plurality of third counterweights 22c vertically stacked; the third counterweights 22c are connected by a fourth bolt fastener 26.

[0058] In this embodiment, through the cooperation of the mounting clip 211, the first counterweight 22a, the second counterweight 22b, the first bolt fastener 23 and the second bolt fastener 24, stable connection with the metal sheet support can be realized, without the need to make changes such as hole opening on the metal sheet support, that is, without the need to change the original structure of the refrigerator 1, the additional counterweight assembly 2 can be directly installed on the existing refrigerator 1.

[0059] In this embodiment, in order to avoid the influence of the nut on the second bolt fastener 24 on the arrangement of the third counterweight 22c, as shown in Figure 5 the second bolt fastener 24 sequentially penetrates the third counterweight 22c and the first clamping plate 2111 from top to bottom, and is then threadedly connected to the second counterweight 22b.

[0060] In this embodiment, the mounting clip 211 is provided with two, the first counterweight 22a is arranged across the two mounting clips 211, and the second counterweight 22b is arranged across the two mounting clips 211. In other embodiments, the number of mounting clips 211 can be adjusted according to actual needs.

[0061] In this embodiment, as shown in Figure 1 and Figure 6As shown, the first counterweight 22a, the second counterweight 22b and the third counterweight 22c are in L-shaped distribution. The reasonable distribution enables to fully utilize the limited space of the bottom of the refrigerator 1 and the approach opening of the installation chamber 11, and to achieve sufficient counterweight in the limited space. The refrigeration components in the installation chamber 11 and the counterweight 22 are not protruded from the external contour of the refrigerator 1.

[0062] In some embodiments, as shown in Figure 4 and Figure 6 As shown, the cross section of the sheet metal support strip 12 is in C-shaped as a whole, which includes a web plate 121, both sides of the web plate 121 extend with flange plates 122, the flange plates 122 are bent away from the edges of the web plate 121 to form hook portions 123, and the hook portions 123 and the web plate 121 form clamping grooves (not labeled in the figure); the side of the first counterweight 22a protrudes with a clamping strip 221, the clamping strip 221 is clamped in the clamping groove, and the hook portions 123 of the sheet metal support strip 12 are supported at the bottom of the clamping strip 221.

[0063] In the embodiment, the structure of the sheet metal support strip 12 itself is fully utilized, and the structure of the first counterweight 22a is reasonably designed, so that the first counterweight 22a can be better combined with the sheet metal support strip 12; the clamping strip 221 of the first counterweight 22a is supported by the hook portions 123, which can reduce the load of the second clamping plate 2112 and avoid the easy bending and deformation of the second clamping plate 2112; at the same time, the combination stability between the mounting clamp 211 and the sheet metal support strip 12 can be improved.

[0064] Further, as shown in Figure 6 and Figure 7 As shown, the top of the web plate 121 of the sheet metal support strip 12 forms a protruding strip 1211 arranged along the length direction thereof; the first clamping plate 2111 of the mounting clamp 211 is bent to form a recess 2115, and the recess 2115 is used for buckling on the protruding strip 1211. Similarly, the structure of the first clamping plate 2111 is reasonably designed by fully utilizing the structure of the sheet metal support strip 12 itself, and when the first clamping plate 2111 and the second clamping plate 2112 are contracted, the cooperation between the recess 2115 and the protruding strip 1211 can further improve the anti-disengagement ability between the mounting rack and the sheet metal support strip 12.

[0065] In some embodiments, as shown in Figure 4 and Figure 6As shown, a strip-shaped hole 2114 is formed in the second clamping plate 2112, and the length direction of the strip-shaped hole 2114 is arranged along the front-rear direction of the refrigerator 1; a third bolt fastener 25 is arranged in the strip-shaped hole 2114, and the third bolt fastener 25 is threadedly connected with the first counterweight block 22a. During installation, the third bolt fastener 25 can be pre-tightened, so that the first counterweight block 22a can move forward and backward on the second clamping plate 2112; after the clamping strip 221 is inserted into the clamping groove of the metal support strip 12, the third bolt fastener 25 is locked, so that the first counterweight block 22a is fixed relative to the second clamping plate 2112, thereby facilitating installation.

[0066] Preferably, in the above scheme, Figure 6 As shown, the two sides of the second counterweight block 22b abut against the connecting plate 2113 of the mounting frame and the flange plate 122 of the metal support strip 12, respectively. The distance between the first counterweight block 22a and the second counterweight block 22b can be adjusted by adjusting the third bolt fastener 25, so that the second counterweight block 22b can abut against the side surface of the flange plate 122, thereby improving the connection stability of the mounting clamp 211 and the metal support strip 12 and increasing the support capacity for the third counterweight block 22c.

[0067] In summary, the application provides a front-tilting-preventing counterweight structure of a refrigerator, which has at least the following beneficial effects:

[0068] By additionally installing the additional counterweight assembly 2 on the refrigerator 1, the center of gravity of the refrigerator 1 as a whole is moved backward, thereby significantly improving the anti-front-tilting-overturning capability of the refrigerator 1 in various use scenarios and effectively preventing the refrigerator 1 from front-tilting-overturning due to improper operation or accidental collision.

[0069] The additional counterweight assembly 2 uses the original metal support strip 12 of the refrigerator 1 as a support point and combines the counterweight block 22 with the metal support strip 12 through the connecting frame 21, thereby not only effectively adding the counterweight but also fully utilizing the structural strength of the refrigerator 1 itself, avoiding structural deformation or damage caused by additional loading, and ensuring long-term stable operation of the refrigerator 1.

[0070] The counterweight block 22 is arranged in the bottom of the refrigerator 1 or / and in the installation cavity 11, thereby avoiding the counterweight block 22 from exceeding the external contour of the refrigerator 1, not affecting the appearance and placement flexibility of the refrigerator 1, eliminating the risk of tripping or space interference caused by the additional protruding part, and ensuring the applicability of the refrigerator 1 in various commercial environments.
