Description

Technical Field

[0001] This invention belongs to the field of clothing processing equipment. Specifically, it relates to a shock-absorbing connection device for a pulsator washing machine, and also to a washing machine having the above-mentioned shock-absorbing components. Background Technology

[0002] During the spin-drying process of a fully automatic washing machine, the outer tub shakes or sways as the motor starts, generating significant vibration and noise. Therefore, to reduce vibration and noise during spin-drying, most fully automatic washing machines are equipped with shock-absorbing components. The outer tub is suspended within the washing machine housing by these components, which feature shock-absorbing elastic parts. These elastic parts cushion the outer tub's eccentricity when it shakes or sways, thus achieving vibration reduction.

[0003] The shock-absorbing spring components of existing washing machine shock-absorbing parts are generally set on the suspension rod of the shock-absorbing part and suspended from one end of the washing machine outer tub. In order to accommodate the installation of the shock-absorbing spring components, a corresponding installation structure needs to be designed on the outer tub of the washing machine. The structure design of the outer tub is relatively complex and occupies a certain amount of space in the outer tub.

[0004] In addition, in order to reduce the amount of expansion and contraction of the shock-absorbing components caused by the swaying of the outer tub, damping components can generally be added so that the amount of expansion and contraction movement generated by the shock-absorbing components is reduced by the damping force provided by the damping components, thereby further reducing the vibration during the operation of the washing machine. However, the damping components on the existing shock-absorbing components generally provide damping force for the relative sliding between the components added to the shock-absorbing components, and do not directly act on the suspension rod. This results in problems such as complex structure of the shock-absorbing components and too many components.

[0005] In view of this, the present invention is proposed. Summary of the Invention

[0006] The technical problem to be solved by the present invention is to overcome the shortcomings of the prior art. The purpose is to provide a shock-absorbing component for a washing machine, in which a shock-absorbing spring is set in the middle of the shock-absorbing component to reduce the space occupied by the shock-absorbing component. At the same time, another purpose of the present invention is to provide a shock-absorbing component for a washing machine so that the damping component can directly apply damping force to the telescopic rod, thereby simplifying the structure of the shock-absorbing component.

[0007] To solve the above-mentioned technical problems, the basic concept of the technical solution adopted by the present invention is as follows: A shock-absorbing component for a washing machine is provided, comprising a first hanger and a second hanger, which are coaxially connected to form a telescopic pair; the connecting ends of the first hanger and the second hanger are inserted into each other, and an elastic element and a damping element are provided at the insertion point; the elastic element connects the first hanger and the second hanger in a relatively elastic telescopic movement; the damping element is fixed to either the first hanger or the second hanger and makes frictional contact with the other hanger in a relatively sliding manner, for providing damping force for the relative telescopic movement of the first hanger and the second hanger; hanger seats are respectively installed at the far end of the first hanger and the far end of the second hanger.

[0008] Furthermore, the damping element is fixed to the first boom; the damping element is in contact with the outer peripheral wall of the second boom, and the friction between the contact surfaces constitutes a damping force that restricts the relative extension and retraction of the first boom and the second boom.

[0009] Furthermore, the damping element is fixedly installed on the first boom; or, the damping element is clamped and fixed between the elastic element and the first boom.

[0010] Furthermore, the two ends of the elastic element are respectively connected to the first rod and the second rod; or, the elastic element is clamped between the connecting end of the first rod and the connecting end of the second rod.

[0011] Furthermore, the connecting end of the first boom is provided with a support structure, the support structure is provided with a plug hole coaxially arranged with the first boom, and the support structure is provided with a telescopic space; the connecting end of the second boom passes through the plug hole and is inserted into the telescopic space; the elastic element is clamped between the connecting end of the second boom and the support structure.

[0012] Furthermore, the support structure includes multiple forked rod portions, each forked rod portion being a forked portion of the connecting end of the first rod, each forked rod portion being eccentrically disposed with respect to the main body of the first rod and extending in a direction parallel to the main body of the first rod; a support base, the ends of the forked rod portions being fixedly connected to the support base, the support base having insertion holes coaxially formed with the first rod and the second rod, the connecting end of the second rod passing through the insertion holes; the eccentric space between each forked rod portion and the main body of the first rod constitutes a telescopic space, used to allow the connecting end of the second rod to extend into the insertion holes after passing through them, providing axial telescopic movement space for the connecting end of the second rod.

[0013] Furthermore, the damping element includes a damping ring located at the insertion hole; the damping ring is fixedly installed on the support base, or the damping ring is clamped between the support base and the elastic element, for fixing the damping ring to the support base in the axial direction of the boom; the damping ring is sleeved on the second boom, and the inner peripheral sidewall of the damping ring contacts the outer peripheral sidewall of the second boom to form an annular contact surface; the friction between the annular contact surfaces constitutes a damping force that restricts the relative telescopic movement of the first boom and the second boom.

[0014] Furthermore, the elastic element is a spring, which is coaxially arranged with the first and second booms, and is sleeved on the portion of the second boom located in the telescopic space; the first end of the spring is provided with a first spring seat, which abuts against the support seat, and the damping ring is clamped and installed between the first spring seat and the support seat; or, the first end of the spring directly abuts against the support seat, the support seat is provided with a fixing cover, and the damping ring is fixedly installed between the support seat and the fixing cover; the second end of the spring is provided with a second spring seat, which is fixedly connected to the connecting end of the second boom.

[0015] Furthermore, the first boom and / or the second boom are provided with water-blocking caps to cover the damping element provided at the joint between the first boom and the second boom.

[0016] Furthermore, any one or a combination of the boom seat, support seat, fixing cover, spring seat, and water-blocking cap is provided with a perforated hole that runs through the boom along the axial direction. The perforated hole is located in the central region of the radial direction of the above-mentioned components and is used to guide the water flow on the components away from the outer wall of the first boom and / or the second boom.

[0017] The present invention also provides a washing machine, including a cabinet and a washing tub assembly disposed in the cabinet, the washing tub assembly being hung in the cabinet by a washing machine shock-absorbing component as described in any of the above claims; either a first hanger seat or a second hanger seat of the washing machine shock-absorbing component is connected to the cabinet, and the other is connected to the washing tub assembly.

[0018] By adopting the above technical solution, the present invention has the following beneficial effects compared with the prior art.

[0019] With the above arrangement, the damping component and the elastic component are located at the connection of the two hangers, so as to achieve the effect of setting the damping and shock absorption component in the middle of the shock absorption component. This can reduce the height of the shock absorption component protruding below the washing tub assembly and reduce the hanging space occupied by the washing tub assembly.

[0020] With the above configuration, the damping element is directly fixed to either the first or second rod, and the damping element is in sliding contact with the other rod. This allows the relative expansion and contraction between the first and second rods to be hindered by the sliding friction between the contact surfaces of the damping element and the other rod. This achieves the purpose of directly applying the damping force provided by the damping element to the rod components, thereby achieving a significant technological advancement in shortening the transmission path of the damping force and simplifying the structure of the shock-absorbing components.

[0021] At the same time, the present invention has a simple structure, significant effects, and is suitable for widespread use.

[0040] like Figures 1 to 10 As shown, this embodiment of the invention provides a washing machine shock-absorbing component 100, which is a washing machine hanger structure. The shock-absorbing component 100 includes a first hanger 1 and a second hanger 2, which are coaxially arranged. The opposing ends of the first hanger 1 and the second hanger 2 are connected, so that the first hanger 1 and the second hanger 2 constitute a telescopic pair capable of generating relative axial telescopic displacement. The connected ends of the first hanger 1 and the second hanger 2 are the connection ends of the first hanger 1 and the second hanger 2, respectively, and the non-connected ends of the first hanger 1 and the second hanger 2 are the mounting ends of the first hanger 1 and the second hanger 2, respectively. For ease of description, the mounting end of the first hanger 1 can be referred to as the first hanger 1's... The first end 11 and the connecting end of the first hanger 1 are the second end 12 of the first hanger 1. The connecting end of the second hanger 2 is the first end 21 of the second hanger 2, and the mounting end of the second hanger 2 is the second end 22 of the second hanger 2. An elastic element 3 is provided at the insertion connection of the first hanger 1 and the second hanger 2. The two ends of the elastic element 3 are respectively connected to the first hanger 1 and the second hanger 2, so that the first hanger 1 and the second hanger 2 that are inserted into each other can form an elastic connection with adjustable expansion and contraction using the elastic element 3. This allows the expansion joint formed by the first hanger 1 and the second hanger 2 to adjust the overall axial length elastically, so as to achieve the effect of shock absorption and support connection between the connected parts at both ends.

[0041] Furthermore, in this embodiment of the invention, the ends of the first suspension rod 1 and the second suspension rod 2 that are relatively far apart, i.e., the mounting ends of the first suspension rod 1 and the second suspension rod 2, are respectively equipped with suspension rod seats 7, so that the two ends of the shock-absorbing component 100 can be connected to the washing machine housing 200 and the washing tub assembly 300 respectively, thereby realizing that the washing tub assembly 300 of the washing machine is suspended in the washing machine housing 200 through the shock-absorbing component 100, thereby achieving the effect of shock-absorbing support installation of the washing tub assembly 300.

[0042] In this embodiment of the invention, a damping element 4 is also provided at the joint of the first rod 1 and the second rod 2. The damping element 4 provides damping force for the relative telescopic movement of the first rod 1 and the second rod 2. The damping element 4 is directly fixed to either the first rod 1 or the second rod 2 and slides in contact with the other rod, so that the relative telescopic movement between the first rod 1 and the second rod 2 is hindered by the sliding friction between the contact surface of the damping element 4 and the other rod. This achieves the purpose of directly using the damping force provided by the damping element 4 on the rod component, thereby achieving a significant technical advancement of shortening the transmission path of the damping force and simplifying the structure 100 of the shock absorption component.

[0043] Example 1

[0044] like Figures 1 to 3As shown in the figure, an embodiment of the present invention introduces a shock-absorbing component for a washing machine, which includes: a first suspension rod 1 and a second suspension rod 2, which are coaxially connected to form a telescopic pair; the second end 12 of the first suspension rod 1 and the first end 21 of the second suspension rod 2 are inserted into each other, and an elastic element 3 is provided between them for adjustable relative telescopic movement between the first suspension rod 1 and the second suspension rod 2; a damping element 4 is provided at the insertion point of the first suspension rod 1 and the second suspension rod 2, and the damping element 4 provides damping force for the relative telescopic movement of the first suspension rod 1 and the second suspension rod 2; suspension rod seats 7 are respectively installed at the far ends of the first suspension rod 1 and the second suspension rod 2; that is, the first end 11 of the first suspension rod 1 is equipped with a first suspension rod seat 71, and the second end 22 of the second suspension rod is equipped with a second suspension rod seat 72.

[0045] In this embodiment, the damping element 4 is fixed to the first boom 1, so that the damping element 4 is fixed to the first boom 1 in the axial direction of the boom. The damping element 4 is in contact with the outer peripheral wall of the second boom 2, and the friction between the contact surfaces constitutes a damping force that restricts the relative extension and retraction of the first boom 1 and the second boom 2. The damping element 4 can be any existing structure, but it needs to satisfy the requirement that the damping element 4 is relatively fixed to the first boom 1 in the axial direction of the boom. The fixing method of the damping element 4 can be any or a combination of the following existing methods. For example, the damping element 4 can be integrated into the first boom 1, or it can be fixed to the first boom 1 by being fixedly installed, or it can be fixed to the first boom 1 by being clamped and fixed between the elastic element 3 and the first boom 1, etc.

[0046] like Figures 1 to 3 As shown, in this embodiment, the fixed position of the damping element 4 fixedly installed on the first suspension rod 1 is taken as an example for discussion. The specific structure is as follows:

[0047] In this embodiment, the second end 12 of the first rod 1 is provided with a support structure, which includes a support 5 and a telescopic space 6. The support 5 is provided with a insertion hole 50 coaxially arranged with the first rod 1. The first end 21 of the second rod 2 passes through the insertion hole 50 on the support 5 and is inserted into the telescopic space 6, so that the first end 21 of the second rod 2 can be axially telescopically inserted into the second end 12 of the first rod 1. The elastic member 3 is located in the telescopic space 6, and the two ends of the elastic member 3 abut against the first end 21 of the second rod 2 and the support 5 respectively, so that the elastic member 3 is compressed and installed at the relative insertion point of the first rod 1 and the second rod.

[0048] In this embodiment, in order to allow the first end 21 of the second rod 2 to pass through the insertion hole 50 of the support base 5, a telescopic space 6 can be provided on the first rod 1. The telescopic space 6 can be specifically configured as follows: at least one forked rod portion 13 is provided at the second end 12 of the first rod 1, which is eccentrically positioned to one side. The forked rod portion 13 is parallel to and eccentrically positioned with respect to the main body of the first rod 1. The two ends of the forked rod portion 13 are integrally connected to the main body of the first rod 1 and fixedly connected to the support base 5, so that the first end 21 of the second rod 2 passing through the support base 5 and the second end 12 of the first rod 1 are staggered, thereby achieving the effect of axial telescopic movement and insertion between the first rod 1 and the second rod 2. The eccentric space between the forked rod portion 13 and the main body of the first rod 1 constitutes the telescopic space 6 for the corresponding insertion of the first end of the second rod 2.

[0049] Meanwhile, preferably, to ensure the smoothness of the telescopic movement between the first boom 1 and the second boom 2, the second end 12 of the first boom 1 is provided with multiple branched rods 13 branching in different directions. Each branched rod 13 extends parallel to the main body of the first boom 1, eccentrically, and symmetrically arranged with respect to the axis of the main body of the first boom 1. One end of each branched rod 13 is connected to the main body of the first boom 1, and the other end is fixedly connected to the support base 5. More preferably, the second end 12 of the first boom 1 is provided with branched rods 13 extending eccentrically and parallel to opposite sides, and the space between the branched rods 13 on both sides constitutes the telescopic space 6.

[0050] In this embodiment, the damping element 4 can be any existing structural form, such as: ring, block, disc, sheet, etc. In order to improve the balance of the damping force applied on the relatively sliding rod, preferably, the damping element 4 is set as a ring with a certain axial extension height, that is, a damping ring 40. The damping ring 40 is sleeved on the outer periphery of the second rod 2, and the inner peripheral sidewall of the damping ring 40 is in close contact with the outer peripheral sidewall of the second rod 2. The damping ring 40 is fixedly installed on the support base 5 so that when the second rod 2 generates axial extension and contraction relative to the first rod 1, a damping force is applied at the annular contact surface between the inner peripheral sidewall of the damping ring 40 and the outer peripheral sidewall of the second rod 2.

[0051] In this embodiment, the damping ring 40 is coaxially arranged with the insertion hole 50. The damping ring 40 is located on the side of the support base 5 facing the first rod 1. The side of the support base 5 facing the first rod 1 is also provided with a fixing cover 33 fastened to the outer periphery of the damping ring 40. The fixing cover 33 is a cylindrical shape that is sleeved on the outer periphery of the damping ring 40. The end of the cylindrical fixing cover 33 near the first rod 1 is bent inward and extends to cover at least a portion of the corresponding end face of the damping ring 40 facing the first rod 1. The end of the cylindrical fixing cover 33 facing the second rod 2 is fixedly connected to the support base 5. The fixed connection between the fixing cover 33 and the support base 5 can be any existing method. For example, the support base 5 has an annular support rib 53 protruding towards the first rod 1 at its center. The enclosed central space forms a channel coaxially arranged with the insertion hole 50, for the first end 21 of the second rod 2 to be inserted through; the protruding end face of the annular support rib 53 corresponds to and abuts against the end face of the damping ring 40 facing the second rod 2; the part of the cylindrical fixing cover 33 facing the second rod 2 is sleeved on the outer periphery of the annular support rib 53, and the end of the cylindrical fixing cover 33 facing the second rod 2 abuts against the support seat 5; the inner peripheral wall of the cylindrical fixing cover 33 is provided with a groove 331, and the outer periphery of the annular support rib 53 is provided with a protruding protrusion 531; the protrusion 531 and the groove 331 are engaged and fixed together, so that the fixing cover 33 and the support seat 5 are relatively engaged and fixed in the axial direction, and the damping ring 40 is fixedly installed between the fixing cover 33 and the support seat 5.

[0052] In this embodiment, in order to improve the assembly stability between the fixing cover 33 and the support base 5, the outer periphery of the support base 5 facing the first hanger 1 is provided with an annular limiting rib 54 protruding towards the first hanger 1, so that the side of the support base 5 facing the first hanger 1 is set as an annular limiting groove 52 with a slot opening towards the first hanger 1; the part of the cylindrical fixing cover 33 facing the second hanger 2 is inserted into the limiting groove 52, and the end of the cylindrical fixing cover 33 facing the second hanger 2 abuts against the bottom of the limiting groove 52; preferably, the end of the cylindrical fixing cover 33 facing the second hanger 2 is provided with an annular support flange 332 protruding outward radially, the end face of the annular support flange 332 facing the second hanger 2 is in contact with the bottom surface of the limiting groove 52, and the outer peripheral sidewall of the annular support flange 332 is in contact with the inner peripheral sidewall of the limiting groove 52.

[0053] In this embodiment, in order to improve the assembly stability between the fixed cover 33 and the support base 5, a gasket 9 made of elastic material can be provided between the fixed cover 33 and the support base 5. The gasket 9 is an annular gasket laid at the bottom of the limiting groove 52 of the support base 5. The two end faces of the gasket 9 are respectively in contact with the corresponding end faces of the fixed cover 33 and the support base 5 to achieve stability of the contact between the fixed cover 33 and the support base 5.

[0054] Meanwhile, in this embodiment, the protruding end face of the annular limiting rib 54 provided on the outer periphery of the support base 5 is higher than the protruding end face of the annular support rib 53 provided at the center of the support base 5, so that at least a portion of the damping ring 40 overlaps with the cylindrical fixing cover 33 and the annular limiting rib 54, thereby ensuring the stability of the damping ring 40 being clamped and fixed.

[0055] In this embodiment, the elastic element 3 can be an existing elastic component that can provide elastic limiting force for the telescopic displacement between the first rod 1 and the second rod 2, such as a spring 30, a hydraulic rod, a pneumatic rod, etc. The two ends of the elastic element 3 are respectively connected to the first rod 1 and the second rod 2, so that the relative position between the interlocking first rod 1 and the second rod 2 can be maintained in a relatively fixed normal position under the elastic force of the elastic element 3; and when the first rod 1 and the second rod 2 are subjected to external force, they can overcome the elastic force of the elastic element to generate relative telescopic displacement, so as to achieve the effect of adjustable relative telescopic displacement of the first rod 1 and the second rod 2.

[0056] In this embodiment, the discussion will focus on the elastic element 3 being a spring 30, as detailed below:

[0057] Spring 30 is coaxially arranged with the first rod 1 and the second rod 2. Spring 30 is sleeved on the outer periphery of the first end of the second rod 2 that passes through the support base 5 and is located in the telescopic space 6. The radial dimension of spring 30 is greater than the outer radial dimension of the damping ring 40, greater than the outer radial dimension of the fixing cover, smaller than the inner radial dimension of the annular limiting rib 54 on the outer periphery of the support base 5, and smaller than the width of the distance between the bifurcated rod portions 13 of the second end 12 of the first rod 1 that are bifurcated to opposite sides, so that the compression or extension deformation generated by spring 30 will not interfere with the first rod 1 and the second rod 2 and other components.

[0058] The end of the spring 30 facing the first rod 1 is the second end 12. The second end of the spring 30 is equipped with a second spring seat 32, which is fixed to the first end 21 of the second rod 2. The first end 21 of the spring 30 facing the second rod 2 abuts against the support seat 5, and the end of the spring 30 is inserted into the annular limiting groove 52 between the outer peripheral side wall of the fixed cover 33 and the outer peripheral annular limiting rib 54 of the support seat 5. This allows the spring 30 to be clamped between the support seat 5 and the first end 21 of the second rod 2 at the second end 12 of the first rod 1. This achieves the effect of clamping and assembling the spring 30 using the insertion telescopic space 6 between the two rods. It also represents a significant technological advancement that the first rod 1 and the second rod 2, which are respectively located on the inner and outer peripheries, can respectively prevent the spring 30 from tilting and limit its movement.

[0059] In this embodiment, two forked rod portions 13 are provided at the connecting end of the first rod 1. The two forked rod portions 13 branch out to the left and right sides from the connecting end of the first rod 1 and extend eccentrically. The extended ends of the forked rod portions 13 are inserted into the mounting holes 55 provided on opposite sides of the outer periphery of the support base 5, so as to achieve the purpose of fixing the two forked rod portions 13 of the first rod 1 to the support base 5. At the same time, the gap space between the two forked rod portions 13 forms a telescopic space 6 for the first end 21 of the second rod 2 to pass through the support base 5 and partially overlap with the first rod 1, allowing the first end 21 of the second rod 2 to move telescopically. The two forked rod portions 13 are symmetrically arranged with respect to the axis of the first rod 1 and the second rod 2, and the distance between the two forked rod portions 13 is greater than the outer radial dimension of the first rod 1, the second rod 2, the fixing cover 33, the spring 30, and the damping ring 40.

[0060] In this embodiment, the first boom 1 and / or the second boom 2 are provided with water-blocking caps 8 to block the damping member 4 provided at the joint of the first boom 1 and the second boom 2, so as to prevent water flowing along the outer wall of the boom from entering the damping member 4 and causing the damping force between the damping member 4 and the second boom 2 to fail. Preferably, the second boom 2 is provided with water-blocking caps 8, which are sleeved in the telescopic space 6 where the second boom 2 passes through the support base 5 and overlaps with the forked rod portion 13 of the first boom 1. The inner peripheral wall of the water-blocking cap 8 is fitted and fixed to the outer peripheral wall of the second boom 2, and the radial dimension of the outer peripheral portion is larger than the outer peripheral radial dimension of the fixed cover 33, so as to prevent the water flowing along the outer wall of the second boom 2 from flowing to the damping ring 40. The water-blocking cap 8 is an annular structure with a radial dimension larger than that of the fixed cover 33. The center of the water-blocking cap 8 is inserted through the second hanger 2. The inner circumference of the water-blocking cap 8 is a conical or hemispherical surface. The conical or hemispherical surface gradually increases in radial dimension from the center outward towards the elastic element 3, so as to guide the water on the side of the water-blocking cap 8 away from the elastic element to flow away from the second hanger 2, thereby preventing the water flowing along the outer wall of the hanger from flowing towards the damping ring 40. At the same time, a perforated hole 10 can be provided at the junction of the outer circumference of the conical or hemispherical surface of the water-blocking cap 8 and other parts of the water-blocking cap. The perforated hole 10 penetrates the water-blocking cap 8, so that the water blocked by the water-blocking cap 8 flows downward from the perforated hole 10 at a certain distance from the outer wall of the second hanger 2, further preventing the water from flowing towards the damping ring 40. In addition, one or more sealing rings can be provided at the contact point between the water-blocking cap 8 and the second rod 2. The sealing rings are made of elastic rubber material to effectively prevent the water flowing along the second rod 2 from continuing to flow along the outer wall of the second rod 2 towards the damping ring 40 from the gap between the second rod 2 and the water-blocking cap 8.

[0061] Preferably, in the axial direction of the boom, the distance between the fixing cover 33 installed on the second boom 2 and the support base 5 is greater than or equal to the maximum telescopic distance between the first boom 1 and the second boom 2, so as to prevent the excessive compression deformation between the first boom 1 and the second boom 2, which could cause the spring 30 to break under compression or exceed the maximum elastic deformation of the shock-absorbing support device 100.

[0062] In this embodiment, a perforated hole 10 is provided on any or a combination of the components, including the boom seat 7, support seat 5, fixing cover 33, and spring seat, extending along the axial direction of the boom. The perforated hole 10 is located in the central region of the radial direction of the aforementioned components, serving to guide the water flow on the components away from the outer wall of the boom and prevent the water flowing along the outer wall of the boom from flowing towards the contact surface between the damping member 4 and the boom. To effectively prevent the water flowing down from the perforated hole 10 of the aforementioned components from flowing towards the damping member 4, the distance between the perforated hole 10 and the axis of the first boom 1 and the second boom 2 can be set to be greater than the outer radial dimension of the damping member 4. In particular, this can effectively prevent the water flowing down from the perforated hole 10 from entering the contact surface between the damping member 4 and the second boom 2.

[0063] Example 2

[0064] like Figures 4 to 6 As shown, this implementation, based on the above-described Embodiment 1, also has the following distinguishing technical features:

[0065] The damping element 4 is installed in the mounting groove 51 provided on the support base 5, and the support base 5 is fixedly installed with a fixing cover 33; the damping element 4 is fixedly installed in the mounting groove 51 between the fixing cover 33 and the support base 5.

[0066] An installation groove 51 can be provided at the center of the support base 5, facing the opening of the telescopic space 6. The installation groove 51 can be formed by a ring-shaped support rib 53 protruding from the middle of the support base 5 toward the telescopic gap. The damping ring 40 constituting the damping member 4 is provided in the installation groove 51 on the support base 5, and the fixing cover 33 is correspondingly fastened and fixed at the opening of the installation groove 51. The fixing cover 33 is ring-shaped and covers at least part of the upper end of the damping member 4, so that the damping member 4 can be fixedly installed on the support base 5, thereby achieving the effect of applying a damping force to the relatively sliding second rod 2.

[0067] Example 3

[0068] This embodiment is based on the above embodiment and has the following differences:

[0069] like Figures 7 to 9As shown, in this embodiment, the damping member 4 is clamped and fixed between the elastic member 3 and the support seat 5 provided at the second end 12 of the first rod 1, so that the damping member 4 and the first rod 1 are fixedly assembled. When the first rod 1 and the second rod 2 have relative telescopic displacement, the damping member 4 generates a damping force at the contact surface with the second rod 2, which is used to prevent the axial relative telescopic movement between the first rod 1 and the second rod 2.

[0070] In order to achieve the damping element 4 being clamped and fixed between the elastic element 3 and the first rod 1, in this embodiment, the fixing cover 33 is removed, and a first spring seat 31 is provided at the end of the spring 30 constituting the elastic element 3 facing the second rod 2. The first spring seat 31 can be fixedly connected to the spring 30, or it can be clamped and fixed between the spring 30 and the support seat 5.

[0071] In this embodiment, the elastic element 3 is clamped between the support seat 5 and the first end 21 of the second rod 2, which are provided at the second end 12 of the first rod 1. The damping ring 40 constituting the damping element 4 is clamped between the support seat 5 and the spring 30, so that the damping ring 40 and the spring 30 are both in the telescopic space 6 between the branch rods 13 of the first rod 1 and also on the outer periphery of the second rod 2. This allows the above components to be simultaneously anti-eccentrically limited by the first rod 1 and the second rod 2, thereby improving the anti-eccentricity strength of the entire shock-absorbing component 100.

[0072] In this embodiment, the elastic element 3 is a spring 30. The spring 30 is sleeved on the outer periphery of the portion of the second rod 2 that passes through the support base 5 and extends into the telescopic space 6. A second spring seat 32 is provided at the end of the spring 30 facing the first rod 1, and the second spring seat 32 is fixedly installed at the first end 21 of the second rod 2. A first spring seat 31 is provided at the end of the spring 30 facing the second rod 2, and the first spring seat 31 abuts against the support base 5. Preferably, a protruding annular limiting rib 54 is provided on the outer periphery of the side of the support base 5 facing the first rod 1, and the first spring seat 31 is fastened to the outer periphery of the damping ring 40, so that the first spring... The inner circumference of the seat 31 is connected to the inner circumference of the damping ring 40. The end of the first spring seat 31 facing the first rod 1 is provided with an inwardly bent annular folded edge 311. The annular folded edge 311 overlaps at least partially with the upper end face of the damping ring 40 facing the first rod 1. The end of the first spring seat 31 facing the second rod 2 extends into the limiting groove 52 surrounded by the annular limiting rib 54. The outer circumference of the end of the first spring seat 31 facing the second rod 2 is in limiting contact with the inner circumferential sidewall of the annular limiting rib 54, so that the damping member 4 is clamped and fixed by the first spring seat 31 and the support seat 5 under the elastic force of the spring 30. Thus, the first spring seat 31 forms a mounting groove 51 with a slot opening in the direction of the support seat 5, and the damping ring 40 is installed in the mounting groove 51 formed by the first spring seat 31; at the same time, the first spring seat 31 is fastened to the support seat 5, so that the support seat 5 covers the slot opening of the mounting groove 51, and the support seat 5 covers at least a portion of the lower end face of the damping ring 40, so as to clamp and fix the damping ring 40 between the support seat 5 and the first spring seat 31.

[0073] The center of the support base 5 is provided with an annular support rib 53 protruding towards the side of the first rod 1. The central space enclosed by the annular support rib 53 forms a channel coaxially arranged with the insertion hole 50, which is used for the first end 21 of the second rod 2 to be inserted through. The protruding end face of the annular support rib 53 corresponds to and abuts against the end face of the damping ring 40 facing the second rod 2. The part of the cylindrical first spring seat 31 facing the second rod 2 is sleeved on the outer periphery of the annular support rib 53, and the end of the cylindrical first spring seat 31 facing the second rod 2 abuts against the support base 5. The end of the spring 30 facing the second rod 2 abuts against the first spring seat 31, so that the first spring seat 31 is clamped and fixed by the spring 30 and the support base 5.

[0074] In this embodiment, the first spring seat 31 can be fixed by the following arrangement: the end of the cylindrical first spring seat 31 facing the second rod 2 is provided with an outwardly radially protruding annular support flange 311. The end face of the annular support flange 311 facing the second rod 2 is in contact with the bottom surface of the limiting groove 52. The outer peripheral sidewall of the annular support flange 311 is in contact with the inner peripheral sidewall of the limiting groove 52. The end of the spring 30 facing the second rod 2 is correspondingly abutted against the annular support flange 311, so that the first spring seat 31 is securely clamped between the spring 30 and the support seat 5.

[0075] In this embodiment, the outer periphery of the support base 5 facing the first rod 1 is provided with an annular limiting rib 54 protruding towards the first rod 1, so as to set the side of the support base 5 facing the first rod 1 as a limiting groove 52 with a slot opening towards the first rod 1; the part of the cylindrical first spring seat 31 facing the second rod 2 is inserted into the limiting groove 52, and the end of the cylindrical first spring seat 31 facing the second rod 2 abuts against the bottom of the limiting groove 52.

[0076] In this embodiment, in order to improve the assembly stability between the first spring seat 31 and the support seat 5, a gasket 9 made of elastic material can be provided between the first spring seat 31 and the support seat 5. The gasket 9 is an annular gasket 9 laid at the bottom of the limiting groove 52 of the support seat 5. The two end faces of the gasket 9 are respectively in contact with the corresponding end faces of the first spring seat 31 and the support seat 5 to achieve stability at the junction of the first spring seat 31 and the support seat 5.

[0077] Preferably, to avoid water accumulation, perforated holes 10 can be provided on the outer periphery of the annular support fold 311 of the first spring seat 31 and the outer periphery of the bottom of the limiting groove 52 of the support seat 5, so that residual water on the first spring seat 31 and the support seat 5 can flow out through the perforated holes 10 around the damping member 4, thereby effectively preventing water flowing along the outer periphery of the rod from entering between the damping member 4 and the rod.

[0081] In this embodiment, the first end 11 of the first rod 1 is provided with a first rod seat 71 that protrudes radially outward, and the second end 22 of the second rod 2 is provided with a second rod seat 72 that protrudes radially outward; the box 200 is provided with a first hanging part, and the outer wall of the outer tub 301 of the washing tub assembly 300 is provided with a second hanging part.

[0082] To achieve the purpose of mounting the washing tub assembly on the cabinet via shock-absorbing components, the following can be done:

[0083] The first hanger seat 71 of the first hanger 1 of the shock-absorbing component 100 is hung from top to bottom on the first hanging part of the box 200, and the second hanger seat 72 of the second hanger 2 is hung from bottom to top on the second hanging part of the outer tub 301, so as to realize that the washing tub assembly 300 is suspended and installed inside the box 200.

[0084] Alternatively, the first hanger seat 71 of the first hanger 1 of the shock-absorbing component 100 is hung from bottom to top on the second hanging part on the outer tub 301, and the second hanger seat 72 of the second hanger 2 is hung from top to bottom on the first hanging part on the box 200, which also enables the washing tub assembly 300 to be suspended and installed inside the box 200.

[0085] In addition, to ensure the stable installation of the washing tub assembly 300, the washing tub assembly 300 can be connected to the housing 200 via multiple shock-absorbing components 100. Each shock-absorbing component 100 is arranged symmetrically with respect to the axis of the outer tub 301 of the washing tub assembly 300. The first hanging rod seat 71 and the second hanging rod seat 72 at both ends of each shock-absorbing component 100 are respectively connected to the first hanging part on the housing 200 and the second hanging part on the outer wall of the outer tub 301 of the washing tub assembly 300, so as to achieve the effect of suspending and hoisting the washing tub assembly 300 via shock-absorbing components 100 in different positions.
