Description

Technical Field

[0001] This utility model relates to a shock-absorbing suspension spring for washing machines, belonging to the field of washing machine spring technology. Background Technology

[0002] The shock-absorbing suspension springs in a front-loading washing machine are used to secure the outer drum inside the machine. The outer drum of a front-loading washing machine is suspended inside the casing, typically supported by two or more suspension springs and shock absorbers.

[0003] The damping components used in existing drum washing machines tend to deteriorate in damping effect over time due to long-term operation and external environmental influences, reducing the stability and shock absorption of the washing machine. Furthermore, the suspension springs are very inconvenient to disassemble and install, and the washing machine may experience problems such as shaking and excessive noise after prolonged operation, making it difficult to perform maintenance. Utility Model Content

[0004] To address the shortcomings of existing technologies, this utility model provides a shock-absorbing suspension spring for washing machines that facilitates the inspection and replacement of the shock-absorbing suspension spring mechanism.

[0005] The technical solution adopted by this utility model to solve the above-mentioned technical problems is as follows:

[0006] A shock-absorbing suspension spring for a washing machine includes a base, a shock-absorbing suspension spring mechanism on one side of the base, a support plate mounted on the base, an mounting plate on one side of the support plate, a damping rod fixedly mounted between the support plate and the mounting plate, first springs arranged around the damping rod, a quick-release structure on the base, the quick-release structure including two symmetrically movably mounted support rods on the base, a plurality of second springs fixedly mounted between the support rods and the base, a locking block fixedly mounted at one end of the support rods, and two symmetrically formed locking slots on the support plate.

[0007] Furthermore, the diameter of the card block matches the inner diameter of the card slot, and the shape of the card block is set as trapezoidal.

[0008] Furthermore, multiple fixing plates are symmetrically fixedly installed on the surface of the base, a first magnetic block is fixedly installed on the fixing plate, and a second magnetic block is fixedly installed on both sides of the support rod.

[0009] Furthermore, multiple anti-slip strips are fixedly installed on the surface of the support rod.

[0010] Furthermore, two sliding rods are symmetrically fixedly installed on the support rod, and the top and bottom of the base are provided with sliding grooves that are slidably connected to the sliding rods.

[0011] Furthermore, a first protective frame is installed on one side of the support plate, and a second protective frame connected to the first protective frame is installed on one side of the mounting plate.

[0012] Furthermore, the first protective frame and the support plate, as well as the second protective frame and the mounting plate, are all connected by multiple bolts, and multiple anti-slip blocks are fixedly installed on the surface of each bolt.

[0013] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0014] This application utilizes a quick-release structure to facilitate the removal of the support plate from the base. Since the base and support plate are fixed together by the engagement of locking blocks and slots, during disassembly, pulling the two support rods moves the locking blocks, causing both blocks to disengage from the slots, thus releasing the fixation. This allows for timely inspection and replacement when the damping effect of the shock absorber suspension spring mechanism deteriorates, preventing any impact on normal operation.

[0021] The present invention and other technical solutions will be further described in detail below with reference to the accompanying drawings and specific embodiments.

[0022] like Figures 1-5As shown in the figure, this embodiment provides a shock-absorbing suspension spring for a washing machine, which includes a base 1. A shock-absorbing suspension spring mechanism 2 is provided on one side of the base 1. The shock-absorbing suspension spring mechanism 2 includes a support plate 3 installed on the base 1. A mounting plate 4 is provided on one side of the support plate 3. A damping rod 5 is fixedly installed between the support plate 3 and the mounting plate 4. First springs 6 are provided around the damping rod 5. A quick-release structure 7 is provided on the base 1. The quick-release structure 7 includes two support rods 8 symmetrically and movably installed on the base 1. Multiple second springs 9 are fixedly installed between the support rods 8 and the base 1. A locking block 10 is fixedly installed at one end of the support rod 8. Two locking slots 11 are symmetrically opened on the support plate 3.

[0023] In this embodiment, as Figures 1-5 As shown, the diameter of the locking block 10 matches the inner diameter of the slot 11, and the shape of the locking block 10 is set as a trapezoid. By setting the diameter of the locking block 10 to match the inner diameter of the slot 11, the locking of the locking block 10 and the slot 11 is more tight and firm, preventing the support plate 3 from loosening. Furthermore, after setting the locking block 10 as a trapezoid, one end of it is inclined, so that during installation, the support plate 3 can be directly pressed into the base 1 to squeeze and move the locking block 10 to complete the locking, without having to pull the locking block 10 during the installation process.

[0024] Multiple fixing plates 12 are symmetrically fixedly installed on the surface of the base 1. A first magnetic block 13 is fixedly installed on the fixing plate 12, and a second magnetic block 14 is fixedly installed on both sides of the support rod 8. Since the support rod 8 is supported by multiple second springs 9, the support rod 8 will retract and reset under the influence of the second springs 9 during disassembly. When disassembling, the support rod 8 is pulled to make the second magnetic blocks 14 on both sides fit with the first magnetic blocks 13. The support rod 8 is fixed by the attraction of the first magnetic blocks 13 and the second magnetic blocks 14, thereby preventing the support rod 8 from moving and resetting during disassembly.

[0025] Multiple anti-slip strips 15 are fixedly installed on the surface of the support rod 8 to increase the friction of the support rod 8 surface and facilitate pulling.

[0026] like Figures 1-5 As shown, two slide rods 16 are symmetrically fixedly installed on the support rod 8, and the top and bottom of the base 1 are provided with slide grooves 17 that are slidably connected to the slide rods 16. The slide rods 16 and slide grooves 17 can reduce the friction between the support rod 8 and the base 1, reduce the resistance during disassembly, and facilitate pulling the support rod 8.

[0027] A first protective frame 18 is installed on one side of the support plate 3, and a second protective frame 19 connected to the first protective frame 18 is installed on one side of the mounting plate 4. The first protective frame 18 and the support plate 3, as well as the second protective frame 19 and the mounting plate 4, are all connected by multiple bolts 20, and multiple anti-slip blocks 21 are fixedly installed on the surface of each bolt 20. The first protective frame 18 and the second protective frame 19 cover the outside of the damping rod 5 and the first spring 6, which can protect the damping rod 5 and the first spring 6 from dust contamination and foreign object collisions that may cause malfunctions or damage. At the same time, the first protective frame 18 and the second protective frame 19 are movably connected, so the damping rod 5 and the first spring 6 are protected without affecting their shock absorption function. The first protective frame 18 and the second protective frame 19 are respectively installed on the support plate 3 and the mounting plate 4 by multiple bolts 20, which facilitates the disassembly and replacement of the first protective frame 18 and the second protective frame 19. The anti-slip blocks 21 increase the friction on the surface of the bolts 20.

[0028] like Figures 1-5 As shown, the working process of the shock-absorbing suspension spring for washing machines provided in this embodiment is as follows: Since the base 1 and the support plate 3 are fixed by the engagement of the locking block 10 and the locking groove 11, during disassembly, the two support rods 8 are pulled to move the locking block 10, so that both locking blocks 10 are disengaged from the locking groove 11. After disengagement, the fixation can be canceled, which facilitates timely inspection and replacement when the damping effect of the shock-absorbing suspension spring mechanism 2 deteriorates. During installation, the support plate 3 is directly inserted into the base 1, and the support plate 3 presses the locking block 10 to move it. After the locking groove 11 and the locking block 10 are aligned, the second spring 9 causes the support rod 8 to reset and drive the locking block 10 to be inserted into the locking groove 11, thus completing the installation and fixation of the support plate 3.

[0029] The foregoing description illustrates and describes preferred embodiments of the present invention. It should be understood that the present invention is not limited to the forms disclosed herein. Any modifications and variations made by those skilled in the art without departing from the spirit and scope of the present invention should be within the protection scope of the appended claims.
