Description

Technical Field

[0001] This utility model relates to the field of drum washing machines, specifically a suspension spring assembly for drum washing machines. Background Technology

[0002] A washing machine drum suspension spring refers to a suspension spring used in the washing machine drum. The suspension spring is used to facilitate the elastic connection between the outer drum and the outer casing. Since the inner drum will generate a lot of shaking during operation, it is necessary to connect the inner drum and release the shaking force. Therefore, the suspension spring is a good choice. However, since both ends of the suspension spring are closed rings, the installation with the fixing ring or fastener on the outer casing is inconvenient. Alternatively, the fixing ring or fastener with an open end may also pose installation risks.

[0003] Application number CN200820036661.X discloses a suspension spring for a drum washing machine, mainly relating to the washing machine's casing and drum assembly. The suspension spring has an upper hook that suspends from the upper corner of the inner side of the casing, which is equipped with a pad. The lower part of the suspension spring is a semi-closed hook that hooks into the suspension hole of the drum assembly. The lower part of the drum assembly is also connected to the casing via a shock absorber. The key feature is that the hook is semi-circular, while the corresponding suspension spring support pad is arc-shaped. After the suspension spring is assembled, the hook rotates around the suspension spring support pad. With the suspension spring described in this invention, the upper hook of the drum washing machine's suspension spring makes arc-shaped contact with the suspension spring support pad of the casing. During movement, the suspension spring rotates around the support pad, resulting in less friction. During the washing machine's spin cycle, the vibration force transmitted to the casing is significantly improved, resulting in a significant effect of vibration reduction and noise reduction.

[0004] However, in the above technical solution, the suspension spring cannot be firmly installed, cannot be fixed in the wind direction, and is easy to detach from the outer shell. Therefore, this utility model proposes a suspension spring assembly for drum washing machines to solve the above-mentioned technical problems. Utility Model Content

[0026] To make the objectives, technical solutions, and advantages of this utility model clear and complete, the embodiments of this utility model will be further described in detail below with reference to the accompanying drawings. It should be understood that the specific embodiments described herein are only some, not all, embodiments of this utility model, and are merely used to explain the embodiments of this utility model. They are not intended to limit the embodiments of this utility model. All other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of this utility model.

[0027] Example 1: Please refer to Figures 1-7 This utility model provides a technical solution: a suspension spring assembly for a drum washing machine, comprising: a washing machine body 1, a drum 2 disposed inside the washing machine body 1, a mounting base 3 disposed inside the washing machine body 1, a positioning plate 4 disposed on the surface of the mounting base 3, a base 5 disposed on the surface of the drum 2, and a threaded tube 6 disposed on the surface of the base 5; a suspension spring 7, a positioning rod 8 disposed at one end of the suspension spring 7, a limit bearing 9 disposed at one end of the positioning rod 8, a threaded rod 10 disposed on the surface of the limit bearing 9, a base plate 11 disposed at the other end of the suspension spring 7, an auxiliary plate 12 disposed on the surface of the base plate 11, and a positioning groove 13 opened on the side of the auxiliary plate 12; a limit plate 14, a limit rod 15 disposed inside the limit plate 14, a moving plate 16 disposed on the surface of the limit rod 15, a slot 17 opened on the surface of the limit plate 14, a traction rod 18 disposed inside the moving plate 16, and a positioning slot 19 disposed on the side of the traction rod 18;

[0028] First, screw the threaded rod 10 into the threaded tube 6 to fix one end of the suspension spring 7. Then, pull the moving plate 16 to move the limiting rod 15 backward. Then, the limiting plate 14 and the auxiliary plate 12 can be inserted into the positioning plate 4. Then, release the moving plate 16 so that one end of the limiting rod 15 is inserted into the positioning slot 13, thereby fixing the other end of the suspension spring 7. Then, insert the positioning card plate 19 into the card slot 17 to prevent the moving plate 16 from displacing and increase the fixing stability of the limiting rod 15, thereby increasing the installation stability of one end of the suspension spring 7.

[0029] Embodiment 2: On the basis of Embodiment 1, in order to facilitate the installation of the suspension spring 7, a positioning rod 8 is provided. One end of the threaded rod 10 is fixedly connected to the inner ring surface of the limiting bearing 9. The auxiliary plate 12 and the limiting plate 14 are fixedly connected to the surface of the bottom plate 11. The limiting plate 14 is in an "L"-shaped plate structure, the positioning plate 4 is in a "匚"-shaped plate structure, the threaded tube 6 is fixedly connected to the surface of the base 5, the threaded rod 10 is screwed into the threaded tube 6, a moving groove 20 is provided on the side surface of the limiting plate 14, a limiting port 21 is provided on the surface of the moving groove 20, the limiting rod 15 is inserted into the moving groove 20, and one end of the limiting rod 15 is inserted into the positioning slot 13;

[0030] During use, first rotate the threaded rod 10 to screw one end of the threaded rod 10 into the threaded tube 6. The setting of the limiting bearing 9 can prevent the suspension spring from rotating when the positioning rod 8 is rotated. Then, pull the moving plate 16 to move the limiting rod 15 backward, so that the limiting rod 15 disengages from the positioning slot 13, and then the bottom plate 11 can be pulled to make the positioning plate 4 located between the limiting plate 14 and the auxiliary plate 12. Then, insert one end of the limiting rod 15 into the positioning slot 13, thereby installing both ends of the suspension spring 7.

A return spring 22 is arranged in the moving groove 20. One end of the return spring 22 is fixedly connected to the end face of the moving groove 20, and the other end of the return spring 22 is fixedly connected to the end face of the limiting rod 15. The moving plate 16 is inserted into the limiting port 21. A lifting groove 23 is provided on the surface of the moving plate 16, and a positioning port 24 is provided on the side surface of the lifting groove 23. A damping rubber ring 25 is sleeved on the outer ring surface of the traction rod 18. The positioning card plate 19 passes through the positioning port 24. The positioning card plate 19 is in an "L"-shaped plate structure. One end of the positioning card plate 19 is inserted into the card slot 17, and the traction rod 18 is inserted into the lifting groove 23;

[0032] When in use, after one end of the limiting rod 15 is inserted into the positioning groove 13, one end of the positioning plate 19 can be inserted into the slot 17.

The surface of the traction rod 18 is fitted with a damping rubber ring 25, which can increase the friction between the traction rod 18 and the side of the lifting groove 23. Then, the elastic force of the return spring 22 is used to push the limiting rod 15, thereby improving the stability of the fixed limiting rod 15.

[0033] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
