Description

Technical Field

[0001] This utility model belongs to the field of mobile home appliances, and in particular relates to a movable refrigerator anti-vibration bracket installation structure. Background Technology

[0002] With the improvement of people's living standards and the diversification of living spaces, refrigerators, as an indispensable electrical appliance in homes and commercial spaces, are being used in increasingly wider scenarios. In actual use, users often need to adjust the position of the refrigerator according to the spatial layout, or move it in scenarios such as cleaning, maintenance, and relocation.

[0003] However, traditional refrigerator moving stands mostly use simple roller structures, which only have basic moving functions. During the movement, when encountering uneven ground, floor seams, thresholds, or other obstacles, external impacts and vibrations are directly transmitted to the refrigerator body through the rollers. This causes the compressor, refrigeration pipes, and internal structure to bear greater mechanical stress, which can easily lead to abnormal operating noises and machine vibrations. It may also cause fasteners to loosen and connection parts to suffer fatigue damage, seriously affecting the refrigerator's operational stability and service life. In addition, when the refrigerator is stationary, these moving stands still keep the wheels on the ground, which cannot provide stable support. Furthermore, the vibrations generated by the refrigerator during operation are transmitted to the floor through the moving stands, which can easily cause floor vibrations, structural sound transmission, and other problems, affecting the quietness of the surrounding environment.

[0004] Therefore, there is a particular need for a movable refrigerator shockproof bracket installation structure to solve the above problems. Utility Model Content

[0005] In order to overcome the shortcomings of traditional refrigerator mobile brackets, such as large vibration transmission when moving, unstable support when stationary, and easy to cause floor vibration and noise, this utility model provides a mobile refrigerator anti-vibration bracket installation structure.

[0006] This utility model is achieved through the following technical means: a movable refrigerator anti-vibration bracket installation structure, including connecting plates, limiting angles, connecting rods, screws, nuts, shock absorbers, base plates, locking components, hinge blocks, connecting blocks, dampers, and polyurethane wheels. Multiple connecting plates are slidably arranged between multiple connecting rods, forming an adjustable load-bearing platform. Locking components are provided between the multiple connecting rods and the multiple connecting plates. A limiting angle is installed on the top of each connecting plate. A screw is threaded onto each connecting plate, and a nut is threaded onto each screw. Below the corresponding connecting plate, each screw has a shock absorber at one end. The fixed end of the shock absorber is fixedly connected to the screw. The movable end of each shock absorber extends downward and is fixedly connected to a base plate. A hinge block is rotatably installed at the bottom of each connecting rod. A connecting block is rotatably installed on both sides of each hinge block. Multiple dampers are arranged in a circular array on each connecting block. The fixed end of the damper is fixedly connected to the connecting block. A polyurethane wheel is installed between multiple dampers distributed along the same running trajectory. The movable end of the damper is fixedly connected to the polyurethane wheel.

[0007] More preferably, the locking assembly includes a mounting base, a plug rod, and a spring. Two mounting bases are fixedly attached to the bottom of each connecting plate. A plug rod is vertically slidably inserted through each mounting base. Multiple insertion holes 1 are equidistantly opened at both ends of each connecting rod along its length. Multiple insertion holes 2 are opened on each connecting plate. The plug rod is inserted into the corresponding insertion hole 1 and the corresponding insertion hole 2. A spring is sleeved on the outside of each plug rod, and the two ends of the spring are fixedly connected to the corresponding plug rod and the corresponding mounting base, respectively.

[0008] More preferably, it also includes rubber pad one and rubber pad two. A rubber pad one is fixedly attached to the top of each connecting plate, and a rubber pad two is fixedly attached to the inner surface of each limiting angle. The rubber pad two is located above and in contact with the corresponding rubber pad one, and together they form a double-layer rubber buffer structure.

[0009] More preferably, it also includes limiting blocks, with two symmetrically distributed limiting blocks fixed to the bottom of each mounting base, and the two limiting blocks contacting the bottom of the corresponding insertion rod.

[0010] More preferably, it also includes a level, with one level installed on each side of the multiple connecting rods that are opposite to each other.

[0011] More preferably, the lowest point of the polyurethane wheel is higher than the bottom surface of the base plate.

[0012] Beneficial effects: 1. Through the coordinated design of hinge blocks, connecting blocks, dampers and polyurethane wheels, multi-directional buffering and shock absorption can be achieved during the movement and transportation of the refrigerator. When encountering obstacles such as uneven ground, seams or thresholds, it can effectively absorb external impact energy and prevent vibration from being directly transmitted to the refrigerator body. It significantly reduces the mechanical stress on the compressor, piping system and internal structure, and reduces the loosening of fasteners and fatigue damage to connection parts caused by bumps.

[0013] Through the linkage structure of screws, nuts, shock absorbers and base plate, stable support can be achieved when the refrigerator is stationary. After the base plate contacts the ground, it forms a support structure. The shock absorber bears the entire load under compression, effectively isolating the vibration generated during refrigerator operation, preventing the vibration from being transmitted to the floor through the bracket mounting structure, avoiding floor vibration and structural sound transmission, significantly reducing operating noise and improving the quietness of the usage environment.

[0014] 2. The bracket installation structure, which uses a sliding fit between the connecting plate and the connecting rod, combined with the quick-release locking mechanism of the plug rod, plug hole one, plug hole two and spring, allows users to quickly adjust the size of the bracket installation structure without tools. It is suitable for refrigerators with different bottom sizes, has strong versatility and wide applicability. Attached Figure Description

Detailed Implementation

[0021] Example: A movable refrigerator shockproof bracket mounting structure, such as... Figures 1-5As shown, the system includes a connecting plate 1, a limiting angle 2, rubber pad 1 21, rubber pad 22, a connecting rod 3, a screw 4, a nut 5, a shock absorber 6, a base plate 61, a locking assembly, a hinge block 11, a connecting block 12, a damper 13, a polyurethane wheel 15, and a level 16. Four connecting plates 1 are slidably arranged between the four connecting rods 3, forming an adjustable load-bearing platform. A locking assembly is provided between the four connecting rods 3 and the four connecting plates 1. A limiting angle 2 is bolted to the top of each connecting plate 1 to limit the sliding of the bottom of the refrigerator and enhance positioning. For stability, a rubber pad 21 is fixedly connected to the top of each connecting plate 1, and a rubber pad 22 is fixedly connected to the inner surface of each limiting angle 2. The rubber pad 22 is located above and in contact with the corresponding rubber pad 21, and together they form a double-layer rubber buffer structure to improve the friction and shock absorption performance between the bottom of the refrigerator and the supporting platform. A screw 4 is threaded on each connecting plate 1, and a nut 5 is threaded on each screw 4. The nut 5 is located below the corresponding connecting plate 1, and a shock absorber 6 is installed at the lower end of each screw 4. The fixed end of the shock absorber 6 is fixedly connected to the screw 4. The movable end of each shock absorber 6 extends downward and is fixedly connected to a base plate 61. When the support structure supports the refrigerator and is placed statically, the base plate 61 contacts the ground, working with the shock absorber 6 to achieve static shock absorption. The base plate 61 has a flower-shaped structure, which can improve the anti-slip performance in a static state. A hinge block 11 is rotatably installed at the center of the bottom of each connecting rod 3. A connecting block 12 is rotatably installed on both sides of each hinge block 11. Each connecting block 12 is provided with a ring array of... Five dampers 13 are provided, with the fixed end of each damper 13 fixedly connected to the connecting block 12. A polyurethane wheel 15 is provided between the five dampers 13 distributed along the same running trajectory. The movable end of each damper 13 is fixedly connected to the polyurethane wheel 15. The lowest point of the polyurethane wheel 15 is higher than the bottom surface of the base plate 61, ensuring that the base plate 61 is in contact with the ground and bears the entire load in the initial state. A level 16 is bolted to each of the four connecting rods 3 on opposite sides, which facilitates real-time observation of whether the bracket installation structure is in a horizontal state.

[0022] like Figure 1 , Figure 3 and Figure 4As shown, the locking assembly includes a mounting base 7, a plug rod 8, a spring 9, and a limiting block 10. Two mounting bases 7 are fixedly connected to the bottom of each connecting plate 1. A plug rod 8 is vertically slidably inserted through each mounting base 7. Multiple insertion holes 81 are equidistantly spaced at both ends of each connecting rod 3 along its length. Multiple insertion holes 82 are formed on each connecting plate 1. The plug rod 8 is inserted into the corresponding insertion hole 81 and the corresponding insertion hole 82, thereby locking the position of the connecting plate 1 on the connecting rod 3. The locking mechanism can be locked by removing the plug rod 8, sliding the connecting plate 1, and re-inserting the plug rod 8. It can be adapted to the bottom of refrigerators of different sizes. Each plug rod 8 is fitted with a spring 9. The upper and lower ends of the spring 9 are fixedly connected to the corresponding plug rod 8 and the corresponding mounting base 7, respectively, to provide a reset force for the plug rod 8. Two symmetrically distributed limit blocks 10 are fixedly connected to the bottom of each mounting base 7. The two limit blocks 10 contact the bottom of the corresponding plug rod 8, thereby limiting the position of the plug rod 8. Only when the plug rod 8 is rotated to 90 degrees and aligned with the distance between the two limit blocks 10 can the plug rod 8 be pulled down to disengage from the current plug hole 1 81 and plug hole 2 82.

[0023] In use, first adjust the size of the support platform according to the bottom size of the refrigerator. Then, rotate the plug rod 8 clockwise by 90 degrees to align its bottom with the gap between the two limit blocks 10. Next, pull the plug rod 8 down to compress the spring 9, so that the plug rod 8 is disengaged from the current plug hole 1 81 and plug hole 2 82, thus unlocking it. Then, slide the connecting plate 1 along the connecting rod 3 to the appropriate position so that the support platform formed by the connecting rod 3 and the connecting plate 1 matches the bottom contour of the refrigerator. After adjustment, half-release the plug rod 8 so that it moves upward and inserts into the corresponding plug hole 1 81 and corresponding plug hole 2 82 under the elastic force of the spring 9. Then, fully release the plug rod 8 so that it rotates counterclockwise by 90 degrees under the torsional force of the spring 9 to offset the gap between the two limit blocks 10, thus relocking the position of the connecting plate 1 on the connecting rod 3.

[0024] After the refrigerator is placed stably on the bracket mounting structure, the screw 4 is rotated clockwise in sequence, causing it to drive the shock absorber 6 and the base plate 61 closer to the connecting plate 1 until the base plate 61 is lifted off the ground. At this time, the polyurethane wheel 15 contacts the ground and bears the entire load, and then the refrigerator can be moved. During the movement, since the polyurethane wheel 15 is connected by five ring-shaped dampers 13, when encountering uneven ground or bumps, the dampers 13 work together to absorb the impact energy and achieve multi-directional buffering and shock absorption. At the same time, the multi-degree-of-freedom structure of the hinge block 11 and the connecting block 12 allows the polyurethane wheel 15 to flexibly turn and adapt to the terrain, improving the stability and maneuverability of the movement.

[0025] After the refrigerator is moved to the target position, rotate the screw 4 counterclockwise in sequence to drive the shock absorber 6 and the base plate 61 away from the connecting plate 1 until the base plate 61 is in complete contact with the ground and bears the full weight of the refrigerator. At this time, the shock absorber 6 is compressed, effectively absorbing the vibration generated by the refrigerator compressor when it starts or stops or runs, preventing the vibration from being transmitted to the floor and achieving static shock absorption. After the adjustment is completed, rotate the nut 5 upward to fit it against the corresponding connecting plate 1 to form an anti-loosening structure and lock the position of the screw 4.

[0026] Subsequently, by observing the level 16, the horizontal status of the bracket installation structure is monitored in real time. If the bracket installation structure is found to be tilted in a certain direction, the base plate 61 at the corresponding position can be independently fine-tuned. For the side where the level 16 shows that it is too low, the screw 4 on that side is rotated counterclockwise to move the base plate 61 further away from the connecting plate 1 and raise the support height on that side. For the side where the level 16 shows that it is too high, the screw 4 is rotated clockwise to appropriately lower the support height on that side. By adjusting the height of the base plate 61 at the four corners point by point, the entire bracket installation structure bearing platform can be accurately leveled to ensure that the refrigerator is in a horizontal working state.
