[0008] As a preferred technical solution, a limiting portion is provided on each of the limit blocks, and the limiting portion has a horizontally arranged limiting end face. The distance between the outer side of each of the limit end faces and the axis of the limit disk is greater than the radius of the bushing mounting hole. An installation guide portion is provided on the outer wall of each of the limit blocks, and the installation guide portion has a guide inclined surface inclined toward the axis of the limit disk.

[0015] By adopting the above technical solution, the beneficial effects of the present invention are as follows: Since the washing machine suspension rod conversion device and the washing machine vibration damper using the conversion device include an upper connecting piece and a lower connecting piece, the device is suitable for various types of washing machine vibration damping suspension rods and can be used to modify existing washing machines. The upper connecting piece is connected to the washing machine vibration damper, and the independent suspension rod is installed between the middle and bottom of the washing machine outer barrel. While not affecting the vibration damping capacity of the original washing machine guide rod, a secondary correction function is added, thereby increasing the correction capacity of the existing washing machine and making the operation of the existing washing machine more stable.

[0016] Since the washing machine hanger conversion device includes a swing angle limiting space, after the device is installed between the washing machine hanger and the washing machine outer drum, during the use of the washing machine, when the washing machine outer drum shakes under the action of centrifugal force, the component force of the washing machine hanger in the horizontal direction hinders the deflection of the washing machine outer drum for the first time. At the same time, the washing machine vibration reduction device will swing in the swing angle limiting space, and the setting of the groove will hinder the swing of the shock absorber housing or the spring support, that is, the device hinders the deflection of the washing machine outer drum for the second time. Therefore, the device not only does not affect the vibration reduction and correction of the washing machine outer drum by the washing machine guide rod, but also adds a secondary correction function, effectively improves the correction ability of the existing washing machine, reduces the shaking of the washing machine outer drum during the operation of the washing machine, and ensures the stability of the washing operation.

[0017] Since the washing machine hanger rod conversion device includes a vibration-damping activity space, after the device is assembled with the existing washing machine hanger rod, the upper hanger rod passes through the through hole, and the washing machine vibration damper is arranged in the vibration-damping activity space. The connection method between the upper hanger rod and the upper connecting piece is more flexible, providing a moving gap for vibration-damping movement. At the same time, this method is fast to install and convenient for maintenance and replacement, and the setting of the vibration-damping activity space provides the vibration damper with the displacement space required for vibration reduction.

[0018] Since the washing machine hanger conversion device includes a bushing, the bushing limit block limits the bushing on the connecting arm, the bushing is constrained and installed in the bushing installation hole, and the elastic clamping claw clamps the connecting arm, so that the upper connecting member and the connecting member are fixedly connected through the bushing and the connecting arm. When the device is installed on an existing washing machine, the existing washing machine and the existing washing machine hanger can be adapted by replacing the connecting arm with an appropriate length. If other types of washing machine hangers are used, it is only necessary to replace the connecting arm without replacing the entire device. In the present invention, the arrangement of the bushing and the connecting arm improves the adaptability of the device.

[0019] After the device is installed together with the existing washing machine hanging rod, the independent hanging rod can be installed between the middle and the bottom of the washing machine outer barrel, which solves the problem of the single installation position of the existing washing machine hanging rod. The position of the washing machine hanging rod installed on the wall of the washing machine outer barrel can be adjusted according to the size of different washing machine outer barrels and the degree of operation swing, thereby improving the adaptability of the existing washing machine hanging rod and the corresponding washing machine outer barrel, enabling the existing washing machine hanging rod to better reduce vibration and correct the deviation of the washing machine outer barrel, thereby ensuring the stability of the washing machine operation.

[0029] Secondly, the lower connecting member 4 includes a first lower horizontal connecting plate 25, which is bent to both sides to form a second lower horizontal connecting plate 26. The second lower horizontal connecting plate 26 is provided with a bushing mounting hole 8, and the independent suspension rod 6 is installed in the bushing mounting hole 8 through a bushing 9.

[0030] The upper suspension rod 1 and the independent suspension rod 6 are coaxially arranged.

[0031] The upper connecting member 3 and the lower connecting member 4 are both symmetrically arranged along the independent suspension rod 6 .

[0032] A bushing limit block 27 is provided at both ends of each connecting arm 7 and at the end of the independent suspension rod 6 close to the lower connecting member 4 , and a rubber pad 28 and a gasket 29 are provided between each limit plate 10 and the adjacent bushing limit block 27 .

[0033] In the first embodiment, the upper connecting member 3 and the lower connecting member 4 are fixedly connected by the connecting arm 7. Only by replacing the connecting arm 7 of different lengths, the washing machine suspension rod conversion device can be adapted to washing machine vibration dampers 32 of different lengths, thereby improving the adaptability of the device to different washing machine vibration dampers 32 and making the upper connecting member 3 and the lower connecting member 4 reusable.

[0034] Embodiment 2: like Figure 4 As shown, this embodiment is basically the same as the first embodiment, except that the intermediate structure includes at least one group of connecting arms 7, each connecting arm 7 includes an upper arm 30 and a lower arm 31, each upper arm 30 is integrally formed with the upper connecting member 3, each lower arm 31 is integrally formed with the lower connecting member 4, and each corresponding upper arm 30 and lower arm 31 are fixedly installed together. In the present invention, the upper arm 30 and the lower arm 31 are fixedly installed together by riveting or bolts. Compared with the first embodiment, the second embodiment can be quickly fixed together, has a simple structure, and is easy to operate.

[0035] Embodiment three: like Figure 1 and Figure 5-Figure 7 As shown together, a washing machine vibration damper, a washing machine vibration damper 32 and an upper suspension rod 1 are installed together to form a washing machine suspension rod, and the washing machine suspension rod conversion device in the first and second embodiments is applied. The washing machine vibration damper 32 includes a vibration damper housing 20 or a spring upper support 21, and the vibration damper housing 20 or the spring upper support 21 is installed in the swing angle limiting space 22. The upper connecting member 3 is installed with the washing machine vibration damper 32, and the lower connecting member 4 is installed with an independent suspension rod 6.

[0037] In the present invention, if Figure 8As shown, according to the physical formula Fx=F×cos(α), F represents the magnitude of the pulling force of the washing machine hanging rod on the washing machine outer barrel 2, Fx represents the component force of F in the horizontal direction, and α represents the inclination angle between F and the horizontal plane. If the inclination angle α between F and the horizontal plane is larger, cos(α) will be smaller, so that the component force Fx of F in the horizontal direction is smaller. The lower end of the washing machine hanging rod without the present device can only be installed at the bottom of the washing machine outer barrel 2. Compared with the washing machine hanging rod without the present device, after the existing washing machine is installed with the present device, the washing machine vibration absorber 32 is connected to the upper connecting member 3, and the independent hanging rod 6 is installed between the middle and the bottom of the washing machine outer barrel 2, that is, the lower end of the existing washing machine hanging rod can be installed between the middle and the bottom of the washing machine outer barrel 2. After installing the present device, the angle between the existing washing machine hanging rod and the washing machine outer barrel 2 is increased, that is, the inclination angle α between the washing machine hanging rod and the horizontal plane is reduced, thereby increasing the component force applied by the washing machine hanging rod to the washing machine outer barrel 2 in the horizontal direction, thereby improving the deviation correction ability of the existing washing machine hanging rod on the washing machine outer barrel 2, so that the operation of the washing machine is more stable.

[0038] In summary, the device is compatible with various types of washing machine hanging rods. The device can be installed between the washing machine hanging rod and the outer barrel of the washing machine to modify the existing washing machine, solving the problem of the single installation position of the washing machine hanging rod in the past. While not affecting the vibration reduction capacity of the original washing machine guide rod, the secondary correction function is added, thereby increasing the correction capacity of the existing washing machine and making the operation of the existing washing machine more stable.

[0039] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention.
