Moreover, without contradiction, those skilled in the art can combine and integrate the different embodiments or examples described in this specification, as well as the features of different embodiments or examples.

[0032] The following is combined Figures 1 to 5 This invention describes the support structure, support system, and refrigerator provided by this utility model.

[0033] See Figures 1 to 3 As shown, the support structure 100 provided in this embodiment of the present invention includes: a first support base 110, a set of movable wheels 120, and a second support base 130.

[0034] The movable wheel assembly 120 includes a plurality of movable wheels 121 arranged parallel to each other and spaced apart. The movable wheels 121 are rotatably connected to the first support base 110, and the bottoms of all the movable wheels 121 are located on the same plane. The second support base 130 is rotatably connected to the first support base 110. The rotation axis of the second support base 130 and the first support base 110 is located between the plurality of movable wheels 121 arranged at intervals. The second support base 130 is configured to be connected to the bottom of the refrigerator body 300.

[0035] The support structure 100 provided by this utility model enables the bottoms of multiple parallel and spaced movable wheels 121 in the movable wheel set 120 to effectively contact the ground, thereby effectively dispersing the pressure on the ground, preventing the ground from being under excessive pressure and causing indentations or damage, and reducing the processing accuracy and assembly accuracy requirements of the support structure 100.

[0036] During operation, the support structure 100 is connected to the bottom of the refrigerator body 300. The weight of the refrigerator is transmitted through the second support base 130 to the first support base 110 and then to the moving wheels 121 of the moving wheel set 120. Since the second support base 130 is rotatably connected to the first support base 110, and the rotation axes of the second support base 130 and the first support base 110 are located between the spaced moving wheels 121, when the refrigerator applies pressure to the support structure 100, the first support base 110 can rotate slightly relative to the second support base 130. This causes each moving wheel 121 in the moving wheel set 120 to rotate with the first support base 110 relative to the second support base 130, and the moving wheels 121 located on both sides of the rotation connection point between the second support base 130 and the first support base 110 can effectively contact the ground, thereby effectively dispersing the pressure on the ground. Furthermore, when moving the refrigerator, the first support base 110 can also rotate slightly relative to the second support base 130, so that each moving wheel 121 can always keep in close contact with the ground and distribute the pressure on the ground.

[0037] Furthermore, since there may be machining errors in the various components of the support structure 100 and assembly errors when the support structure 100 is assembled with the refrigerator, the slight rotation of the first support seat 110 relative to the second support seat 130 when pressure is applied to the refrigerator can automatically compensate for these errors, thereby reducing the requirements for machining accuracy and assembly accuracy of the support structure 100.

[0038] Specifically, the support structure 100 includes a first support base 110, a set of movable wheels 120, and a second support base 130.

[0039] Both the first support base 110 and the second support base 130 can provide support for the refrigerator, and are usually made of durable materials with good load-bearing capacity, such as steel or other high-strength materials.

[0040] The caster wheel assembly 120 provides support for the refrigerator body 300 and facilitates refrigerator movement. The caster wheel assembly 120 includes multiple parallel and spaced-apart casters 121, rotatably connected to a first support base 110. The bottoms of all casters 121 are on the same plane. When the first support base 110 rotates relative to the second support base 130, all casters 121 rotate synchronously with the first support base 110 relative to the second support base 130, ensuring that the bottoms of each caster 121 remain on the same plane during rotation, thus ensuring that each caster 121 contacts the ground synchronously. The number of casters 121 in the caster wheel assembly 120 can be two or more, without limitation. For example, the appropriate number of casters 121 can be selected based on the refrigerator's weight, volume, and actual usage needs to prevent excessive pressure from a single caster 121 on the ground.

[0041] As an example, in this embodiment, both the first support base 110 and the second support base 130 are made of bent metal profiles, which have good load-bearing capacity and durability. Through the bending process of the metal profiles, the first support base 110 and the second support base 130 can be precisely shaped, ensuring the stability and strength of the support structure 100, suitable for bearing the weight of the refrigerator. The moving wheel set 120 includes two moving wheels 121, both of which are rotatably connected to the first support base 110 to meet the needs of refrigerator transfer. The bottoms of the two moving wheels 121 are located on the same plane. In actual use, the rotation of the first support base 110 relative to the second support base 130 can drive the two moving wheels 121 to rotate synchronously, ensuring that they always maintain stable and uniform contact with the ground, avoiding uneven pressure.

[0042] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the support structure 100 further includes a plurality of first rotating shafts 140 corresponding one-to-one with the movable wheel 121. The first rotating shaft 140 is detachably connected to the first support base 110, and the movable wheel 121 is rotatably sleeved on the corresponding first rotating shaft 140.

[0043] By setting the first rotating shaft 140, the movable wheel 121 and the first support base 110 can be rotatably connected via the first rotating shaft 140, ensuring that the movable wheel 121 can rotate flexibly as the refrigerator moves. When the refrigerator is moved, the first rotating shaft 140 remains fixed, and the movable wheel 121 rotates relative to the first rotating shaft 140. Since the first rotating shaft 140 and the first support base 110 are detachably connected, the installation and replacement of the movable wheel 121 can be made simpler. For example, when the movable wheel 121 is worn or needs to be replaced, the first rotating shaft 140 can be removed and a new movable wheel 121 can be replaced without disassembling the entire support structure 100, improving the convenience of maintenance and repair.

[0044] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the first rotating shaft 140 passes through the first support base 110 and is threadedly connected to the first support base 110, and also includes a first fixing nut 150. The first rotating shaft 140 passes through the first support base 110 and is threadedly connected to the first fixing nut 150.

[0045] By threading the first rotating shaft 140 through the first support base 110 and connecting it to the first support base 110, and threading it to the first fixing nut 150, it is possible to ensure that the first rotating shaft 140 is firmly fixed to the first support base 110 and facilitates disassembly and assembly.

[0046] Specifically, the first rotating shaft 140 passes through the first support base 110, and its threaded connection with the first support base 110 ensures that it is fixed to the support base, preventing loosening during use. At the same time, the threaded connection between the first rotating shaft 140 and the first support base 110 using a first fixing nut 150 further enhances the connection stability between the first rotating shaft 140 and the first support base 110. There is at least one first fixing nut 150.

[0047] As an example, in this embodiment, the first rotating shaft 140 adopts a bolt structure, the movable wheel 121 is sleeved on the smooth part of the screw, and the threaded part of the screw is threadedly connected to the first support base 110 and the first fixing nut 150. During assembly, the movable wheel 121 is pre-fixed in a set position, and its internal through hole is aligned with the corresponding mounting hole on the first support base 110. Then, the first rotating shaft 140 is inserted through the first support base 110 and the movable wheel 121, and then the first rotating shaft 140 is tightened. Its structure is simple and easy to assemble and disassemble.

[0048] In some embodiments, the first rotating shaft 140 may simply be threadedly connected to the first support base 110, without the need for a first fixing nut 150 for further reinforcement. Correspondingly, in some embodiments, only the first fixing nut 150 may be provided to fix the first rotating shaft 140, without the need to open a screw hole on the first support base 110. In this case, the first fixing nut 150 and the first support base 110 may be separately provided, or the first fixing nut 150 may be fixed to the corresponding position of the first support base 110 by welding or other processes.

[0049] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the support structure 100 further includes a second rotating shaft 160, which is detachably connected to the first support base 110 and the second support base 130, and the second support base 130 is rotatably disposed on the second rotating shaft 160.

[0050] By setting the second rotating shaft 160, the second support base 130 and the first support base 110 can be rotatably connected, ensuring that the first support base 110 can rotate relative to the second rotating shaft 160 with the second rotating shaft 160 as the center. When the refrigerator applies pressure to the support structure 100, the first support base 110 can rotate slightly relative to the second support base 130, causing each of the moving wheels 121 in the moving wheel set 120 to rotate with the first support base 110 relative to the second support base 130. This ensures that the moving wheels 121 located on both sides of the rotation connection point between the second support base 130 and the first support base 110 can effectively contact the ground, thereby effectively dispersing the pressure on the ground. Since the second rotating shaft 160 and the second support base 130 are detachably connected, the first support base 110 can be removed from the second support base 130 for maintenance or replacement of components such as the first support base 110 or the moving wheels 121.

[0051] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the second rotating shaft 160 passes through the first support seat 110 and the second support seat 130 and is threadedly connected to the second support seat 130. It also includes a second fixing nut 170, and the second rotating shaft 160 passes through the second support seat 130 and is threadedly connected to the second fixing nut 170.

[0052] By threading the second rotating shaft 160 through the first support 110 and the second support 130 and threading it with the second support 130, as well as threading it with the second fixing nut 170, the first support 110 can be stably rotatedly connected with the second support 130, preventing the second rotating shaft 160 from loosening and causing the first support 110 and the second support 130 to detach from the connection.

[0053] Specifically, the second rotating shaft 160 passes through the first support 110 and the second support 130. Its threaded connection to the second support 130 ensures stable fixation, preventing loosening during use. Simultaneously, the threaded connection of the second fixing nut 170 to the second rotating shaft 160 further enhances the connection stability between the second rotating shaft 160 and the second support 130. At least one second fixing nut 170 is used.

[0054] As an example, the second rotating shaft 160 in this embodiment also adopts a bolt structure. The first support seat 110 is sleeved on the smooth part of the screw, and the threaded part of the screw is threadedly connected to the second support seat 130 and the second fixing nut 170. During assembly, the first support seat 110 is pre-fixed in the set position, and the mounting holes on both sides are aligned with the mounting holes on the first support seat 110. Then, the second rotating shaft 160 is inserted through the first support seat 110 and the second support seat 130, and then the second rotating shaft 160 is tightened. Its structure is simple and easy to assemble and disassemble.

[0055] In some embodiments, the second rotating shaft 160 may simply be threadedly connected to the second support base 130, without the need for a second fixing nut 170 for further reinforcement. Correspondingly, in some embodiments, only the second fixing nut 170 may be provided to fix the second rotating shaft 160, without the need to drill a screw hole in the second support base 130. In this case, the second fixing nut 170 and the second support base 130 may be separately provided, or the second fixing nut 170 may be fixed to the corresponding position of the second support base 130 by welding or other processes.

[0056] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the second rotating shaft 160 is located between adjacent moving wheels 121, and in the working state, the bottom of the second rotating shaft 160 is lower than the top of the moving wheels 121.

[0057] By placing the second pivot 160 between adjacent moving wheels 121, and in the working state, with the bottom of the second pivot 160 lower than the top of the moving wheels 121, the spatial compactness of the support structure 100 can be improved, the overall height of the support mechanism can be reduced, and the center of gravity of the refrigerator can be lowered, making it more stable when moving or stationary.

[0058] See Figures 1 to 3 As shown, according to some embodiments of the present invention, the support mechanism further includes a braking assembly 180. The braking assembly 180 includes an adjusting member 181 and a braking member 182. The braking member 182 is disposed on the adjusting member 181. The adjusting member 181 is axially movably connected to the first support seat 110 to drive the braking member 182 to switch between a braking state and a non-braking state. In the braking state, the braking member 182 abuts against the moving wheel 121. In the non-braking state, there is a gap between the braking member 182 and the moving wheel 121.

[0059] By setting the braking component 180, the refrigerator can be fixed in position and the moving wheel 121 can be braked to prevent the refrigerator from accidentally sliding or tilting when not in use.

[0060] Specifically, when the refrigerator needs to be kept in a fixed position, the braking component 180 can drive the braking component 182 through the adjusting component 181 to firmly fix the moving wheel 121 in the braking state, ensuring that the refrigerator is stable and does not move due to uneven ground or external interference.

[0061] The adjusting member 181 is axially movable and connected to the first support base 110 in various ways, such as threaded connection, sliding connection, or snap-fit. When the adjusting member 181 is threadedly connected to the first support base 110, the distance between the braking member 182 and the moving wheel 121 can be adjusted by rotating the adjusting member 181, thereby adjusting the braking state. When the adjusting member 181 is slidably connected to the first support base 110, the distance between the braking member 182 and the moving wheel 121 can be adjusted by sliding the adjusting member 181, thereby adjusting the braking state. After the adjusting member 181 slides to a predetermined position, its position can be fixed by a locking element (such as a locking pin or locking screw). When the adjusting member 181 is snap-fitted to the first support base 110, the distance between the braking member 182 and the moving wheel 121 can be adjusted by changing the snap-fit ​​position of the adjusting member 181 and the first support base 110, thereby adjusting the braking state.

[0062] In addition to the above methods, the adjusting member 181 can also be axially movable to the first support 110 by other methods known in the prior art, and there is no limitation on this.

[0063] The braking component 182 can be a friction braking component such as a rubber pad. The end of the braking component 182 abuts against the moving wheel 121, and the braking effect is achieved by generating braking force through friction. The rubber pad has a high coefficient of friction, which can generate sufficient friction between the contact surfaces to effectively slow down or stop the movement of the moving wheel 121.

[0064] It should be noted that the number of braking components 180 can be single or multiple, without limitation. For example, the appropriate number of braking components 180 can be selected according to the weight and volume of the refrigerator and actual usage requirements to prevent excessive braking pressure from a single braking component 180, which could lead to ineffective braking. Furthermore, within each braking component 180, the adjusting element 181 and the braking element 182 can be a single set or multiple sets.

[0065] As an example, in this embodiment, there is one braking assembly 180. The braking assembly 180 includes a single adjusting member 181 and a braking member 182. During braking, the single braking assembly 180 is used to brake the outer movable wheel 121, thereby achieving overall braking of the support mechanism. The adjusting member 181 in the braking assembly 180 is located on the outer side for easy manual operation.

[0066] See Figures 1 to 3As shown, according to some embodiments of the present invention, the adjusting member 181 is threadedly connected to the first support seat 110 so that when the adjusting member 181 is rotated, the braking member 182 moves axially.

[0067] By configuring the adjusting member 181 and the first support base 110 with a threaded connection, the braking member 182 can be moved axially by rotating the adjusting member 181, making the adjustment process more precise and controllable. Users can easily adjust the position of the braking member 182 simply by rotating the adjusting member 181, thereby achieving a stable fixation or release of the refrigerator or other equipment when needed. The threaded connection provides a stable mechanical connection and allows for precise axial adjustment, ensuring the equipment maintains the required stability and safety. Furthermore, the threaded connection has a self-locking characteristic; once the adjusting member 181 is rotated to the set position, no fixing mechanism is required to secure it, resulting in a simple structure.

[0068] See Figures 1 to 3 As shown, according to some embodiments of the present invention, a first receiving groove 111 is formed in the first support base 110, at least a portion of the movable wheel set 120 is located in the first receiving groove 111, and both sides of the movable wheel 121 are rotatably connected to the first support base 110.

[0069] By providing a first receiving groove 111 within the first support base 110, the compactness of the support structure 100 can be significantly improved. Specifically, the first receiving groove 111 accommodates at least a portion of the movable wheel assembly 120 within the first support base 110, maximizing space utilization. Furthermore, the side walls of the first support base 110 can protect at least a portion of the rotating wheels in the movable wheel assembly 120, preventing debris from entering the connection between the movable wheel 121 and the first rotating shaft 140.

[0070] See Figures 1 to 3 As shown, according to some embodiments of the present invention, a second receiving groove 131 is formed in the second support 130, at least a portion of the first support 110 is located in the second receiving groove 131, and both sides of the second support 130 are rotatably connected to the first support 110.

[0071] By providing a second receiving groove 131 within the second support base 130, the compactness of the support structure 100 can be further improved. Specifically, the second receiving groove 131 can accommodate at least a portion of the first support base 110 within the second support base 130, maximizing the use of space.

[0072] The support system provided by this utility model is described below. The support system described below can be referred to in correspondence with the support structure 100 described above.

[0073] See Figure 4As shown, the support system provided in this embodiment of the present invention includes: two support modules, which are spaced apart along a first direction; each support module includes a telescopic connecting rod 200, both ends of which are provided with a support structure 100 as described in any of the previous embodiments, and the telescopic connecting rod 200 is arranged along a second direction.

[0074] It should be noted that both "first direction" and "second direction" mentioned above refer to... Figure 5 The arrows shown in the diagram indicate the direction of the refrigerator's width. The first direction can be understood as the width of the refrigerator, and the second direction can be understood as the depth of the refrigerator.
