Description

Technical Field

[0001] This utility model relates to a hinge structure for a drum washing machine. Background Technology

[0002] The door of a drum washing machine is connected to the body by a hinge. This inexpensive and simple structure consists of only two hinges connected by a pin. Since the opening and closing of the drum door requires force to pull and collide, the connection is very easy to loosen. Furthermore, when closing the drum door, the force of the collision can cause the connection to bend excessively, leading to the hinges coming loose more quickly and causing the drum door to become loose. Utility Model Content

[0003] To overcome the above-mentioned shortcomings, this utility model provides a hinge structure for a drum washing machine, which has a more secure connection and a longer service life.

[0004] To achieve this objective, the structure adopted in this utility model is: a hinge structure for a drum washing machine, including a main connecting plate. The main connecting plate is a long strip-shaped plate structure with arc-shaped sides. Fixing holes penetrating the main connecting plate are provided at both ends of the main connecting plate. Pin connecting arms are symmetrically arranged on both sides of the surface of the main connecting plate. One side of the pin connecting arm is bent in an arc towards the center of the main connecting plate and connected to the main connecting plate. A shaft hole is provided on the other side. A limit block is provided on the main connecting plate below the shaft hole of each pin connecting arm. A buckle and a positioning post are provided at the bottom of the main connecting plate.

[0005] The bottom of the main connecting plate is provided with a rectangular groove with a depth of 1 to 3 mm. The rectangular groove is located between the two pin connecting arms and has a width of 1 / 2 to 2 / 3 of the width of the main connecting plate.

[0006] An L-shaped buckle is provided next to the fixing hole on one side of the bottom of the main connecting plate, and a conical positioning post is provided next to the fixing hole on the other side.

[0007] The bottom of the main connecting plate has evenly distributed rectangular deep grooves.

[0008] An arc-shaped recess is provided between the two pin connecting arms on the front of the main connecting plate, and the width of the arc-shaped recess is 2 / 3 to 4 / 5 of the width of the main connecting plate.

[0009] The arc-shaped bend of the pin connecting arm and the inner side of the limiting block form an elongated oval structure ring, with a gap between the pin connecting arm and the limiting block.

[0010] The main connecting plate has mounting grooves around the fixing holes on the front side.

[0011] The main connecting plate, pin connecting arm and limiting block are integrally pressed aluminum alloy and powder coated on the surface.

[0012] Its beneficial effects are: the structure of this utility model is reasonably and ingeniously designed. The pin connecting arm extends the lever arm, reducing the impact of switching impact on the main connecting plate. At the same time, the buckle and positioning post ensure the connection stability of the bolts in the fixing hole, further reducing the impact of impact on structural stability and extending the service life of the structure.

[0018] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," and "connected," etc., should be interpreted broadly. For example, "connected" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components; a fixed connection can be welding or adhesive bonding. Those skilled in the art can understand the specific meaning of the above terms in this utility model according to the specific circumstances.

[0019] like Figure 1 , Figure 2The hinge structure of the drum washing machine shown includes a main connecting plate 1, which is a long strip-shaped plate with arc-shaped sides. This arc-shaped structure allows for better fit with the circular door opening of the drum washing machine, resulting in more even force distribution on the connection and fixing parts. The main connecting plate 1 has fixing holes 6 at both ends, which are secured using pins or bolts. Symmetrically arranged on both sides of the main connecting plate 1 are pin-shaft connecting arms 2. One side of each pin-shaft connecting arm 2 is curved towards the center of the main connecting plate and connects to it, while the other side has a shaft hole 3. The thickness of the pin-shaft connecting arm 2 gradually decreases from its connection point with the main connecting plate 1 towards the shaft hole 3. The end connected to the shaft hole 3 is parallel to the main connecting plate 1. The shaft hole 3 between two pin-shaft connecting arms 2 is used to fix the two ends of the pin connecting to the drum door. A limit block 4 is provided on the main connecting plate 1 below the shaft hole 3 of each pin-shaft connecting arm 2. A buckle 8 and a positioning post 10 are provided at the bottom of the main connecting plate 1.

[0020] The pin connecting arm 2 extends the lever arm, reducing the impact of switching shocks on the main connecting plate 1. At the same time, the buckle 8 and the positioning post 10 ensure the connection stability of the bolts in the fixing hole 3, further reducing the impact of impacts on structural stability and extending the service life of the structure.

[0021] A rectangular groove 9 is provided at the bottom of the main connecting plate 1. The depth of the rectangular groove 9 is 1-3mm. The rectangular groove 9 is located between the two pin connecting arms 2, and its width is 1 / 2 to 2 / 3 of the width of the main connecting plate 1. When installing the hinge, adhesive is applied to the rectangular groove 9 to increase the adhesive area, improve the stability of the connection and the overall structural strength.

[0022] An L-shaped buckle 8 is provided next to the fixing hole 6 on one side of the bottom of the main connecting plate 1, and a conical positioning post 10 is provided next to the fixing hole 6 on the other side. The positioning post 10 is used for initial positioning, and then the buckle 8 is used for temporary connection, and also helps to distribute the force on the bolts in the fixing hole 6.

[0023] The bottom of the main connecting plate 1 has evenly distributed rectangular deep grooves 11. The deep grooves 11 can reduce the overall weight, and the connecting parts between the deep grooves 11 can distribute the overall force and strengthen the overall structural strength.

[0024] An arc-shaped recess 7 is provided between the two pin connecting arms 2 on the front side of the main connecting plate 1. The width of the arc-shaped recess 7 is 2 / 3 to 4 / 5 of the width of the main connecting plate 1.

[0025] The arc-shaped bend of the pin connecting arm 2 and the inner side of the limiting block 4 form an elongated oval structural ring 12, with a gap between the pin connecting arm 2 and the limiting block 4. Since some drum washing machines have self-cleaning devices on their drum doors, and these devices require pipes, the structural ring 12 and the arc-shaped recess 7 provide a certain space for the pipes.

[0026] The main connecting plate 1 has a mounting groove 5 around the fixing hole 6 on the front side. After installation, the end of the bolt is hidden in the mounting groove 5, so that there are no other protruding structures on the overall surface except for the pin connecting arm 2 and the limiting block 4, which is conducive to the flatness of the overall surface and the installation.

[0027] The main connecting plate 1, the pin connecting arm 2, and the limiting block 4 are integrally pressed and formed from aluminum alloy, with a powder coating treatment. After powder coating, the surface is smoother and does not require polishing. It also makes the whole structure more corrosion-resistant and wear-resistant, extending the service life of the overall structure.

[0028] Based on the above description and inspired by this utility model, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model. The technical scope of this utility model is not limited to the contents of the specification, but must be determined according to the scope of the claims.
