Description

Technical Field

[0001] This utility model relates to the technical field of washing machine vibration damping devices, and in particular to a rubber sealing ring, a rubber sealing assembly and its washing machine vibration damping assembly. Background Technology

[0002] Most top-loading washing machines use vibration damping components. Existing vibration damping components include a suspension rod and a vibration damping sealing sleeve. From top to bottom, the suspension rod is fitted with a vibration damping spring, a spring plastic support, and a rubber sealing ring. Vibration damping is achieved through frictional damping generated by the relative movement between the rubber sealing ring and the vibration damping sealing sleeve, and damping generated by air discharge. Figure 1 As shown, the existing rubber sealing ring has an annular groove 1 at its bottom. The annular groove 1 weakens the overall structural strength of the rubber sealing ring. During vibration damping, when the rubber sealing ring is subjected to pressure or vibration, its support capacity is insufficient, making it prone to deformation. This prevents the outer edge of the rubber sealing ring from tightly fitting against the inner wall of the vibration damping sleeve, and also results in poor sealing between the inner side of the rubber sealing ring and the hanger rod. This reduces the sealing performance and damping force between the rubber sealing ring and the vibration damping sleeve, thus worsening the vibration damping effect of the washing machine's vibration damping assembly. To solve these problems, such as... Figure 2 As shown, a tension spring 2 is installed in the annular groove 1 of the existing rubber seal to increase the support capacity of the rubber seal to the outer edge. However, the tension spring 2 and the rubber seal have poor cooperation effect and low reliability.

[0003] Therefore, there is a need for a rubber sealing ring, a rubber sealing assembly, and a vibration damping assembly for washing machines that can solve the above problems. Utility Model Content

[0004] This utility model proposes a rubber sealing ring, a rubber sealing assembly, and a washing machine vibration damping assembly. Through reinforcing ribs, a plastic lower support, and a plastic pressure cap, the rubber sealing ring body achieves dual support and limitation. When applied to the washing machine vibration damping assembly, the vibration damping effect of the washing machine vibration damping assembly is significantly improved.

[0005] The first technical solution of this utility model is implemented as follows:

[0006] A rubber sealing ring includes a rubber sealing ring body, wherein the bottom of the rubber sealing ring body is provided with an annular groove, characterized in that the annular groove is provided with a plurality of reinforcing ribs, and the two ends of each reinforcing rib are respectively connected to the two inner walls of the annular groove, and the rubber sealing ring body is provided with a mounting through hole for mounting a plastic lower support.

[0007] As a preferred technical solution, the rubber sealing ring body, the annular groove, and the reinforcing rib are integrated into one unit.

[0008] As a preferred technical solution, several of the reinforcing ribs are evenly distributed radially within the annular groove.

[0009] As a preferred technical solution, the reinforcing rib is made of rubber.

[0010] The second technical solution of this utility model is implemented as follows:

[0011] A rubber sealing assembly includes the aforementioned rubber sealing ring, wherein the upper end of the plastic lower support passes through the mounting through hole and is inserted with a plastic pressure cap, and the body of the rubber sealing ring is disposed between the plastic pressure cap and the plastic lower support.

[0012] As a preferred technical solution, the plastic lower support includes a first end face and a first column that are integrally formed, and the plastic cover includes a second end face and a hollow second column that are integrally formed. The first column passes through the mounting through hole and is inserted into the second column. Both the first column and the second column are provided with hanging rod mounting through holes.

[0013] As a preferred technical solution, the outer peripheral surface of the first column is in contact with the inner peripheral surface of the mounting through hole.

[0014] As a preferred technical solution, the two ends of the rubber sealing ring body abut against the second end face and the first end face, respectively.

[0015] As a preferred technical solution, the first column is provided with a plurality of first vent holes, and the second column is provided with at least one second vent hole, the second vent hole being connected to the first vent hole.

[0016] The third technical solution of this utility model is implemented as follows:

[0017] The washing machine vibration damping assembly includes the aforementioned rubber sealing assembly, as well as a suspension rod and a vibration damping sealing sleeve. The suspension rod is fitted with a vibration damping spring and the rubber sealing assembly from top to bottom. The rubber sealing assembly is slidably installed inside the vibration damping sealing sleeve. The outer edge of the rubber sealing ring is in contact with the inner wall of the vibration damping sealing sleeve. The vibration damping sealing sleeve and the rubber sealing ring form an air chamber above and below, respectively.

[0018] By adopting the above technical solution, the beneficial effects of this utility model are as follows:

[0019] Since the rubber sealing ring includes the rubber sealing ring body, the reinforcing ribs provide support and compressive elasticity to the outer edge of the rubber sealing ring body, improving the deformation resistance of the outer edge of the rubber sealing ring. When the rubber sealing ring is installed on the washing machine vibration damping assembly for vibration damping, under the action of pressure or vibration, the outer edge of the rubber sealing ring still fits tightly against the inner wall of the vibration damping sleeve, thereby improving the sealing performance and damping force between the outer edge of the rubber sealing ring and the vibration damping sleeve, and thus improving the vibration damping effect and stability of the washing machine vibration damping assembly.

[0020] Since the rubber sealing ring includes a rubber sealing ring body with an installation through hole, the upper support passes through the installation through hole and supports the inner circumferential surface of the installation through hole, which further improves the deformation resistance of the rubber sealing ring during vibration reduction.

[0021] In this invention, the rubber sealing ring body is doubly supported by the upper support and reinforcing ribs, which improves the deformation resistance of the rubber sealing ring during the vibration reduction process. When applied to the vibration reduction assembly of the washing machine, the vibration reduction effect of the washing machine vibration reduction assembly is significantly improved.

[0022] Since the rubber sealing assembly includes a sealing ring, an upper support, and a plastic cap, this utility model limits the rubber sealing ring body by inserting the plastic cap and plastic lower support together. When the rubber sealing ring is applied to the vibration damping assembly of the washing machine for vibration damping, the plastic cap and plastic lower support inserted together drive the rubber sealing ring body to slide inside the vibration damping sleeve. During the sliding process, frictional damping is generated between the rubber sealing ring body and the vibration damping sleeve, and air damping is generated inside the vibration damping sleeve, thereby achieving a stable vibration damping effect.

[0033] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0034] Example 1:

[0035] like Figure 3 and Figure 4 As shown, the rubber sealing ring includes a rubber sealing ring body 3. The bottom of the rubber sealing ring body 3 is provided with an annular groove 1. Several reinforcing ribs 4 are provided in the annular groove 1. The two ends of each reinforcing rib 4 are respectively connected to the two inner walls of the annular groove 1. The rubber sealing ring body 3 is provided with a mounting through hole 6 for installing a plastic lower support 5.

[0036] The rubber sealing ring body 3, the annular groove 1, and the reinforcing rib 4 are integrated into one piece.

[0037] Several reinforcing ribs 4 are evenly distributed radially within the annular groove 1.

[0038] Reinforcing rib 4 is made of rubber.

[0039] Example 2:

[0040] like Figures 5-7As shown in the figure, the rubber sealing assembly includes the rubber sealing ring of Embodiment 1, the upper end of the plastic lower support 5 passes through the mounting through hole 6 and is inserted with a plastic pressure cap 7, and the rubber sealing ring body 3 is disposed between the plastic pressure cap 7 and the plastic lower support 5.

[0041] The plastic lower support 5 includes a first end face 8 and a first column 9 that are integrated together. The plastic cover 7 includes a second end face 10 and a hollow second column 11 that are integrated together. The first column 9 passes through the mounting through hole 6 and is inserted into the second column 11. Both the first column 9 and the second column 11 are provided with hanging rod mounting through holes 12.

[0042] Furthermore, the outer peripheral surface of the first column 9 is in contact with the inner peripheral surface of the mounting through hole 6.

[0043] Furthermore, the two ends of the rubber sealing ring body 3 abut against the second end face 10 and the first end face 8, respectively.

[0044] Secondly, the first column 9 is provided with a number of first vent holes 13, and the second column 11 is provided with at least one second vent hole 14, which is connected to the first vent holes 13.

[0045] Example 3:

[0046] like Figure 8 As shown, the washing machine vibration damping assembly includes the rubber sealing assembly of Embodiment 2, and also includes a suspension rod 15 and a vibration damping sealing sleeve 16. The suspension rod 15 is fitted with a vibration damping spring 17 and a rubber sealing assembly from top to bottom. The rubber sealing assembly is slidably installed inside the vibration damping sealing sleeve 16. The outer edge of the rubber sealing ring is in contact with the inner wall of the vibration damping sealing sleeve 16. An air chamber 18 is formed above and below the vibration damping sealing sleeve 16 and the rubber sealing ring, respectively.

[0047] In this invention, the outer peripheral surface of the first column 9 abuts against the inner peripheral surface of the mounting through hole 6, providing support to the inner wall of the mounting through hole 6. This achieves support of the plastic lower support 5 for the inner side of the rubber sealing ring body 3. Combined with the abutment of the second end face 10 and the first end face 8 against the two ends of the rubber sealing ring body 3, a seal is achieved for the inner side of the rubber sealing ring body 3. This prevents air from flowing between the two air chambers 18 through the mounting through hole 6 during vibration damping. Instead, air flows between the two air chambers 18 only through the first vent hole 13 and the second vent hole 14, improving the vibration damping effect of the washing machine vibration damping component through air damping.

[0048] In summary, this utility model provides dual support and limitation for the rubber sealing ring body through reinforcing ribs, a plastic lower support, and a plastic pressure cap. When applied to the vibration damping component of a washing machine, it significantly improves the vibration damping effect of the washing machine vibration damping component.
