Description

Technical Field

[0001] This utility model relates to the field of washing machine tripod technology, specifically to a highly stable, water-resistant washing machine tripod. Background Technology

[0002] Front-loading washing machines are widely used in the washing machine industry. To ensure stable operation during washing and spin-drying, a tripod is used to fix the inner tub to the rotating shaft. During operation, the motor drives the tripod and inner tub to rotate at high speed. The tripod serves to fix and support the inner tub. To ensure stable washing and spin-drying, the tripod must have sufficient rigidity and strength. However, in actual use and testing, the tripod of a washing machine often breaks at the tail end of the support arm near the rotating shaft. Because the tripod is mainly subjected to radial forces during high-speed rotation of the washing machine, and these forces are very large, there is a large stress concentration at the tail end of the support arm near the rotating shaft, which easily leads to tripod failure. Existing solutions often involve adding more reinforcing ribs, which increases material usage and costs. Furthermore, too many reinforcing ribs, especially those sandwiched between the tripod and the washing tub, make it difficult to clean the area. This allows dirt to easily adhere to the reinforcing ribs, breeding bacteria, causing secondary contamination of the laundry, accelerating the corrosion of the tripod, and shortening the lifespan of the washing machine. Utility Model Content

[0003] The purpose of this invention is to overcome the above-mentioned shortcomings and provide a highly stable, water-resistant washing machine tripod. It features a rational arrangement of reinforcing ribs, reducing the amount of ribs used. By incorporating flanges, arc-shaped reinforcing ribs, and connecting ribs to form a reinforcing section, the connection strength at the base of the tripod body is enhanced, making the tripod structure stable. A pressure-bearing cavity is provided to increase the strength of the support arm. The radial reinforcing ribs, while ensuring the strength of the pressure-bearing cavity, have a reduced height. Combined with the water-permeable holes on the arc-shaped reinforcing ribs, this facilitates the flow of water accumulated at the base of the reinforcing section, reducing internal dirt-trapping corners and making it easier to clean the tripod used in the washing machine, thus improving cleanliness.

[0004] The purpose of this utility model is achieved as follows:

[0005] A highly stable, water-resistant washing machine tripod includes a tripod body with a bushing at its center for mounting a pivot. The tripod body has three support arms extending outwards from its center. Each support arm has a U-shaped groove structure. The outer end of each support arm away from the bushing has a mounting portion for installation with the inner drum of the washing machine. The inner ends of adjacent support arms are connected by an arc segment. Each support arm has an arc-shaped reinforcing rib near the bushing's inner end. A connecting rib is provided between the arc segment and the bushing. A pressure-bearing cavity is formed between the arc-shaped reinforcing rib and the mounting portion. A radial reinforcing rib is provided within the pressure-bearing cavity. Both ends of the radial reinforcing rib are connected to the arc-shaped reinforcing rib and a partition rib on the inner side of the mounting portion, respectively. The radial reinforcing rib is lower than the U-shaped groove wall of the support arm. Adjacent support arms have U-shaped groove openings with flanges. The flanges, arc-shaped reinforcing ribs, and connecting ribs constitute a reinforcing portion. Water-permeable holes are provided on the arc-shaped reinforcing ribs.

[0006] Preferably, the arc-shaped reinforcing ribs, partition ribs, and connecting ribs are at the same height as the U-shaped groove wall of the support arm, and the radial reinforcing ribs extend 5-10mm above the bottom of the U-shaped groove of the support arm.

[0007] Preferably, the three arc-shaped reinforcing ribs are on the same circle, and the center of the circle is located at the center of the tripod body.

[0008] Preferably, the connecting rib has a reinforcing cylinder in the middle, and the diameter of the reinforcing cylinder is greater than the thickness of the connecting rib.

[0009] Preferably, corner braces are provided between the back of the flange and the arc segment, and the three corner braces are evenly distributed circumferentially.

[0010] Preferably, a support rib is provided in the middle of the radial reinforcing rib, the support rib is perpendicular to the radial reinforcing rib, and both ends of the support rib are connected to the inner sidewall of the U-shaped support arm.

[0011] Preferably, a reinforcing cylinder is also provided at the connection between the supporting rib and the radial reinforcing rib, and the reinforcing cylinder here is higher than the supporting rib.

[0012] The beneficial effects of this utility model are:

[0013] This utility model rationally arranges reinforcing ribs, reducing the amount of reinforcing ribs used. By setting flanges, arc-shaped reinforcing ribs, and connecting ribs to form a reinforcing part, the connection strength of the base of the tripod body is enhanced, making the tripod structure stable. A pressure-bearing cavity is set to improve the strength of the support arm. The radial reinforcing ribs are reduced in height while ensuring the strength of the pressure-bearing cavity. In conjunction with the water-permeable holes on the arc-shaped reinforcing ribs, it is easy for water to flow away from the base of the reinforcing part, reducing the dead corners where dirt accumulates inside, so as to facilitate the cleaning of the tripod used in washing machines and improve cleanliness.

Detailed Implementation

[0017] See Figure 1 and Figure 2 This utility model relates to a highly stable, water-resistant washing machine tripod, comprising a tripod body, a bushing 1 for mounting a pivot at the center of the tripod body, and three support arms 2 extending outward from the center of the tripod body. Each support arm 2 has a U-shaped groove structure in cross-section, and the inner ends of adjacent support arms 2 are connected by an arc segment 3. Each support arm 2 has an arc-shaped reinforcing rib 2.1 near the inner end of the bushing 1 and an mounting part 2.2 for mounting to the inner drum of the washing machine at its outer end away from the bushing 1. The three arc-shaped reinforcing ribs 2.1 are on the same circle, with the center of the circle located at the center of the tripod body. A connecting rib 4 is provided between the arc segment 3 and the bushing 1. To improve the connection strength of the connecting rib 4, a reinforcing cylinder 4.1 is provided in the middle of the connecting rib 4. The diameter of the reinforcing cylinder 4.1 is greater than the thickness of the connecting rib 4. The three connecting ribs 4 are evenly distributed around the bushing 1. A pressure-bearing cavity 2.3 is formed between the arc-shaped reinforcing rib 2.1 and the mounting part 2.2. A radial reinforcing rib 2.4 is provided in the pressure-bearing cavity 2.3. The two ends of the radial reinforcing rib 2.4 are respectively connected to the arc-shaped reinforcing rib 2.1 and the partition rib 2.2.1 on the inner side of the mounting part 2.2. The U-shaped groove of the adjacent support arm 2 is provided with a flange 5. The flange 5, the arc-shaped reinforcing rib 2.1 and the connecting rib 4 constitute a reinforcing part, thereby enhancing the connection strength of the base of the tripod body.

[0018] The arc-shaped reinforcing rib 2.1 is provided with a water-permeable hole 2.1.1 to facilitate the drainage of water accumulated inside the reinforcing part and prevent the formation of scale and the growth of bacteria.

[0019] The arc-shaped reinforcing rib 2.1, the partition rib 2.2.1, and the connecting rib 4 are at the same height as the U-shaped groove wall of the support arm 2. The radial reinforcing rib 2.4 is 5-10mm higher than the bottom of the U-shaped groove of the support arm. The radial reinforcing rib 2.4 reduces its height while ensuring the strength of the pressure chamber 2.3, which facilitates water flow and reduces dead corners for internal dirt accumulation, so as to facilitate the cleaning of the tripod used for washing machines and improve cleanliness.

[0020] Because the radial reinforcing rib 2.4 is relatively long, in order to prevent deformation in the middle of the pressure-bearing cavity 2.3, a supporting rib 2.5 is provided in the middle of the radial reinforcing rib 2.4. The supporting rib 2.5 is perpendicular to the radial reinforcing rib 2.4, and both ends of the supporting rib 2.5 are connected to the inner sidewall of the U-shaped supporting arm 2. In order to improve the connection strength, a reinforcing cylinder is also provided at the connection between the supporting rib 2.5 and the radial reinforcing rib 2.4. The reinforcing cylinder here is higher than the supporting rib 2.5.

[0021] An angle brace 6 is provided between the back of the flange 5 and the arc segment 3. The three angle braces 6 are evenly distributed around the circumference to improve the connection strength of the reinforcing part.

[0022] In addition to the above embodiments, this utility model also includes other implementation methods. All technical solutions formed by equivalent transformation or equivalent substitution should fall within the protection scope of the claims of this utility model.
