Description

Technical Field

[0001] The utility model relates to the technical field of washing machine parts, in particular to a washing machine suspension spring with high sealing performance. Background Art

[0002] The washing tub is a part of the washing machine. During the washing process, especially when dehydrating, the washing tub will shake violently. In order to avoid direct transmission of vibration and cause large vibrations in the washing machine body, the washing tub is generally connected to the washing machine shell through suspension springs.

[0003] At present, the existing suspension springs are usually directly exposed to the outside of the washing tub when in use. External dust and moisture can easily cause corrosion and oxidation of the suspension springs, thereby affecting the service life of the suspension springs. At the same time, when installing the suspension springs, it is usually necessary to apply a certain pulling force to stretch the suspension spring to a sufficient length and install the suspension spring during this process. Since a certain pulling force is applied and one end of the suspension spring needs to be installed at a specified position, the installation is relatively inconvenient. Utility Model Content

[0004] In view of the shortcomings of the prior art, the utility model provides a washing machine suspension spring with high sealing performance which is easy to install and use.

[0005] The technical solution adopted by the utility model to solve the above technical problems is:

[0011] Furthermore, the shape and size of the protrusion match the shape and size of the groove.

[0012] Compared with the prior art, the beneficial effects of the utility model are:

[0013] 1. The highly sealed washing machine suspension spring of the present application is designed to connect one end of the suspension spring body to the washing machine shell, connect the connecting hook to the washing machine drum shell, and then rotate the adjusting rod to adjust the stretching length of the suspension spring body.

[0019] The technical solution of the utility model will be clearly and completely described below in conjunction with the accompanying drawings and specific embodiments.

[0020] like Figures 1 to 3As shown in the figure, the high-sealing washing machine suspension spring of this embodiment includes a suspension spring body 1. Hooks 2 are respectively arranged at both ends of the suspension spring body 1. A protective shell 3 is installed outside the suspension spring body 1. A placement cavity 4 is arranged inside the protective shell 3. The suspension spring body 1 is located inside the placement cavity 4. A threaded cavity 5 is arranged at one end of the placement cavity 4. A moving plate 6 is threadedly connected inside the threaded cavity 5. One end of the suspension spring body 1 is connected to the moving plate 6. The other end of the suspension spring body 1 extends outside the protective shell 3. An adjusting rod 7 is installed at the end of the moving plate 6 away from the suspension spring body 1. By rotating the adjusting rod 7 to drive the moving plate 6 to rotate and move, the suspension spring body 1 can be adjusted to maintain an appropriate tensile force, which is convenient for connecting the washing machine shell and the washing machine drum shell.

[0021] A cover 8 is detachably installed at the upper end of the protective shell 3. A connecting hook 18 is installed at one end outside the protective shell 3. By connecting one end of the suspension spring body 1 to the washing machine shell and connecting the connecting hook 18 to the washing machine drum shell, and then rotating the adjusting rod 7 to adjust the stretching length of the suspension spring body 1, the suspension spring body 1 can maintain an appropriate tensile force to pull the washing machine drum shell. And during the installation process, there is no need to apply tensile force while aligning and installing the hook 2, which is convenient for installation and use.

[0022] Specifically, a rotating plate 9 is rotatably connected to one end of the moving plate 6 close to the suspension spring body 1. The rotating plate 9 is installed through a notch or a bearing part to realize the rotating function, effectively preventing the suspension spring body 1 from rotating synchronously with the rotating plate 9. A connecting ring 10 is installed at one end of the rotating plate 9. One hook 2 is connected to the connecting ring 10. Installation holes 11 are arranged at the end of the protective shell 3 away from the connecting hook 18. The other hook 2 extends outside the protective shell 3 through the installation holes 11.

[0023] Furthermore, a sealing sleeve 12 is installed inside the installation holes 11. The hook 2 is in contact with the surface of the sealing sleeve 12. The sealing sleeve 12 ensures the sealing performance at the installation holes 11, effectively preventing external dust and water from entering the protective shell 3 through the installation holes 11.

[0024] Furthermore, one end of the adjusting rod 7 is set to be in a shape of a straight bar, which is convenient for using tools to rotate the adjusting rod 7.

[0025] Furthermore, contact surfaces 13 are arranged at the upper end of the protective shell 3. Grooves 14 are arranged at the upper ends of the contact surfaces 13. Protrusions 15 are installed at the lower ends of the cover 8. Screw holes 16 are arranged on both sides of the surface of the protective shell 3 outside the grooves 14. Screws 17 are threadedly connected inside the screw holes 16. The screws 17 extend into the protrusions 15. By placing the protrusions 15 on the cover 8 inside the grooves 14 and using the screws 17 for connection, the installation of the cover 8 can be realized, achieving high-sealing protection for the suspension spring body 1 and effectively isolating water and dust from entering the protective shell 3.

[0026] Furthermore, the shape and size of the bump 15 match those of the groove 14. The bump 15 and the groove 14 are arranged to facilitate the alignment of the holes on the protective shell 3 and the cover 8, which is convenient for the installation of the screw 17.

[0027] The usage method of this embodiment is as follows: When using the highly sealed washing machine suspension spring, the suspension spring body 1 is located inside the placement cavity 4. Connect the hook 2 at one end of the suspension spring body 1 to the connecting ring 10, and extend the hook 2 at the other end through the sealing sleeve 12 and the mounting hole 11 to the outside of the protective shell 3. Then, install the cover 8 on the protective shell 3 with the screw 17. After this step is completed, connect the hook 2 extending to one end of the protective shell 3 to either the washing machine housing or the drum housing, and connect the connecting hook 18 to the remaining one of the washing machine housing or the drum housing. Then, rotate the adjusting rod 7 to drive the moving plate 6 to rotate. The moving plate 6 moves in the threaded cavity 5 towards the direction of the connecting hook 18. At the same time, the moving plate 6 stretches the suspension spring body 1 to adjust the suspension spring body 1 to maintain an appropriate tension to pull the washing machine drum, which is convenient for installation. When the suspension spring body 1 generates slight tensile fatigue in the future, rotating the adjusting rod 7 again can effectively extend the service life of the suspension spring body 1.

[0028] Finally, it should be noted that the above are only the preferred embodiments of the present invention and are not used to limit the present invention. Those skilled in the art can modify or equivalently replace the technical solutions described in the foregoing embodiments. Any modification, equivalent replacement, etc. made within the spirit and principle of the present invention shall be included within the protection scope of the present invention.
