Description

Technical Field

[0001] This utility model relates to the field of washing machine tripod technology, specifically to a high-strength 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 significant stress concentration at the tail end of the support arm near the rotating shaft, which easily leads to tripod breakage and failure. Utility Model Content

[0003] The purpose of this utility model is to overcome the above-mentioned shortcomings and provide a high-strength washing machine tripod. The support rib is provided with multiple reinforcing columns at radial intervals. The reinforcing columns increase the contact area between the support rib and the U-shaped bottom of the support arm, thereby improving the connection strength of the support rib. At the same time, the inner reinforcing diagonal rib intersects with the support rib at the reinforcing column and forms a 30° angle, extending the length of the inner reinforcing diagonal rib. This allows the inner reinforcing diagonal rib to improve the structural strength while reducing the number of inner reinforcing diagonal ribs. The arc segment, flange, inner end of the support rib, outer reinforcing rib and corresponding inner reinforcing diagonal rib constitute the reinforcing part, making the strength of the connection between the bushing and the support arm at the center high, which can effectively reduce stress concentration and prevent breakage.

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

[0005] A high-strength washing machine tripod includes a bushing and support arms. Three support arms are radially and evenly arranged around the bushing. A rotating shaft is installed inside the bushing. Each support arm has a U-shaped cross-section. The outer side of the support arm away from the bushing has a mounting part. The inner side of the support arm near the bushing is connected to the bushing through an arc-shaped transition section. The support arm has a support rib and an inner reinforcing rib. The support rib is located at the center of the support arm. One end of the support rib is connected to the bushing, and the other end extends radially along the support arm. The support rib has multiple reinforcing columns spaced radially. The multiple inner reinforcing ribs are arranged in pairs, and the two inner reinforcing ribs in each pair intersect each other and intersect with the support rib at the corresponding reinforcing column. A flange is provided between the slots of two adjacent support arms. The back of the flange is provided with an outer reinforcing rib, which is connected to the outer wall of the adjacent support arm.

[0006] Preferably, the inner reinforcing diagonal rib and the supporting rib form a 30° angle.

[0007] Preferably, the inner reinforcing diagonal ribs divide the U-shaped cavity of the support arm into multiple pressure-bearing cavities, which are in the shape of stable triangles or triangular-like cavities.

[0008] Preferably, there are four reinforcing columns, with the two middle reinforcing columns used to connect with the inner reinforcing diagonal bars.

[0009] Preferably, there are two pairs of inner reinforcing diagonal ribs along the length of the support rib, and the end of the pair of inner reinforcing diagonal ribs near the bushing is connected to the end of the arc segment.

[0010] Preferably, the outer reinforcing rib and the corresponding inner reinforcing diagonal rib are on the same straight line.

[0011] Preferably, the height of the outer reinforcing rib is lower than the height of the support arm.

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

[0013] Multiple reinforcing columns are provided at radial intervals along the support ribs. The reinforcing columns increase the contact area between the support ribs and the bottom of the U-shaped support arm, thereby improving the connection strength of the support ribs. At the same time, the inner reinforcing diagonal ribs intersect with the support ribs at the reinforcing columns and form a 30° angle, extending the length of the inner reinforcing diagonal ribs. This allows the inner reinforcing diagonal ribs to improve the structural strength while reducing the number of inner reinforcing diagonal ribs.

[0014] The curved section, flange, inner end of the support rib, outer reinforcing rib, and corresponding inner reinforcing diagonal rib constitute the reinforcing part, which makes the connection between the bushing and the support arm in the center high and can effectively reduce stress concentration to prevent breakage.

[0018] See Figure 1 and Figure 2This utility model relates to a high-strength washing machine tripod, comprising a bushing 1 and three support arms 2. The three support arms 2 are radially and evenly arranged around the bushing 1. A rotating shaft 3 is installed inside the bushing 1. Each support arm 2 has a U-shaped cross-section. The inner side of the support arm 2 near the bushing 1 is connected to the bushing 1 via an arc-shaped segment 2.1. The outer side of the support arm 2 away from the bushing 1 has a mounting part 2.2. The support arm 2 contains a support rib 2.3 and an inner reinforcing diagonal rib 2.4. The support rib 2.3 is located at the center of the support arm 2. One end of the support rib 2.3 is connected to the bushing 1, and the other end extends radially along the support arm 2. The supporting rib 2.3 is provided with multiple reinforcing columns 2.3.1 at radial intervals. The reinforcing columns increase the contact area between the supporting rib 2.3 and the bottom of the U-shaped supporting arm, thereby improving the connection strength of the supporting rib 2.3. Multiple inner reinforcing diagonal ribs 2.4 are arranged in pairs, and the two inner reinforcing diagonal ribs 2.4 in each pair intersect each other and intersect with the supporting rib 2.3 at the corresponding reinforcing column 2.3.1. The inner reinforcing diagonal ribs 2.4 and the supporting rib 2.3 form a 30° angle. The length of the inner reinforcing diagonal ribs 2.4 is extended, so that the inner reinforcing diagonal ribs 2.4 can improve the structural strength while reducing the number of inner reinforcing diagonal ribs 2.4.

[0019] The inner reinforcing diagonal ribs 2.4 divide the U-shaped cavity of the support arm into multiple pressure-bearing cavities, which are in the shape of stable triangles or triangular-like cavities.

[0020] There are four reinforcing columns 2.3.1, with the two middle reinforcing columns 2.3.1 used to connect with the inner reinforcing diagonal ribs 2.4.

[0021] Two pairs of inner reinforcing diagonal ribs 2.4 are provided along the length direction of the support rib 2.3 (radial direction of the support arm). The end of the pair of inner reinforcing diagonal ribs 2.4 near the bushing 1 is connected to the end of the arc segment 2.1.

[0022] A flange 4 is provided between the slots of two adjacent support arms 2. The back of the flange 4 is provided with an outer reinforcing rib 5. The outer reinforcing rib 5 is connected to the outer side wall of the adjacent support arm 2 respectively. The three outer reinforcing ribs 5 are evenly distributed around the circumference of the bushing 1.

[0023] The outer reinforcing rib 5 and the corresponding inner reinforcing diagonal rib 2.4 are on the same straight line to enhance the overall connection strength.

[0024] The arc-shaped segment 2.1, the flange 4, the inner end of the support rib 2.3, the outer reinforcing rib 5, and the corresponding inner reinforcing diagonal rib 2.4 constitute the reinforcing part, which makes the connection between the bushing 1 and the support arm 2 located in the center high, effectively reducing stress concentration and preventing breakage.

[0025] The height of the outer reinforcing rib 4 is lower than the height of the support arm 2, so it does not affect the installation of the tripod and the inner drum of the washing machine, and at the same time facilitates the drainage of accumulated water.

[0026] 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.
