Description

Technical Field

[0001] The utility model relates to the technical field of a washing machine dehydration shaft, in particular to a sealing ring oil seal for a washing machine dehydration shaft. Background Art

[0002] In the design and manufacture of washing machines, the sealing of the dehydration shaft is a very crucial link. Traditional sealing technologies usually adopt simple oil seals. Such an oil seal is generally an annular structure made of rubber or other elastic materials, sleeved on the dehydration shaft, and realizes sealing through contact with the shaft and the housing. However, there are some problems with this traditional oil seal.

[0003] In the existing technology, ordinary oil seals are prone to wear after long-term use, resulting in a decline in the sealing effect. There may be moisture and stains seeping into the interior of the washing machine, and maintenance is difficult. If the traditional oil seal is damaged, it often requires disassembling most of the components of the washing machine to be replaced, increasing the difficulty and cost of maintenance. Therefore, developing a new type of high-performance sealing ring oil seal for a washing machine dehydration shaft is still an important research direction. Content of the Utility Model

[0004] To solve the above technical problems, the utility model provides a sealing ring oil seal for a washing machine dehydration shaft.

[0005] The utility model is realized by adopting the following technical scheme: A sealing ring oil seal for a washing machine dehydration shaft, including a sealing ring body. An internal installation groove is opened inside the sealing ring body. A skeleton installation groove is opened at the bottom of the inner wall of the internal installation groove. A skeleton fixed installation device is fixedly connected inside the skeleton installation groove.

[0006] Through the above technical scheme, through the sealing ring body which is the main part of the oil seal, usually a circular ring structure, its inner diameter is adapted to the outer diameter of the washing machine dehydration shaft to ensure that the oil seal can be tightly sleeved on the dehydration shaft. The outer diameter of the sealing ring body is slightly larger than the outer diameter of the dehydration shaft to provide a certain amount of compression during installation to ensure the sealing effect. An internal installation groove is opened inside it, and the dehydration shaft is sleeved inside the internal installation groove.

[0007] As a further improvement of the above scheme, the skeleton fixed installation device includes a connecting fixed ring. Several installation support rods are fixedly connected to the upper surface of the connecting fixed ring. An empty groove is opened between the installation support rods. A connecting head is fixedly connected to the top of the installation support rod. A clamping block is fixedly connected to one side of the connecting head.

[0008] Through the above technical solution, the device main body is fixed to the washing machine through the skeleton fixing and installing device, preventing it from falling off during use. The skeleton fixing and installing device is clamped to the washing machine body through a clamping block. There is an empty groove between the installation rods, facilitating disassembly during the installation process.

[0009] As a further improvement of the above solution, a raised block is fixedly connected to the middle of the upper surface of the sealing ring body, and a groove is opened in the middle of the upper surface of the raised block.

[0010] Through the above technical solution, the groove facilitates the use of screws for fixation after the sealing ring body is installed, preventing protrusions from causing accidents during device use.

[0011] As a further improvement of the above solution, an installation hole is opened in the middle of the inner wall of the groove, and a first sealing lip is fixedly connected inside the installation hole.

[0012] Through the above technical solution, the first sealing lip is located inside the installation hole. When the dehydration shaft rotates, the first sealing lip contacts the outer surface of the dehydration shaft to prevent moisture and dirt from entering the washing machine interior.

[0013] As a further improvement of the above solution, a connecting column is fixedly connected to the middle of the built-in installation groove, and a second sealing lip is fixedly connected to the outer surface of the connecting column.

[0014] Through the above technical solution, by fixedly connecting the second sealing lip to the outer surface of the connecting column, the second sealing lip is sleeved inside the dehydration shaft, preventing the dehydration shaft from slipping during use, which may cause damage to the device and water to enter the device interior, and also preventing moisture or lubricant from leaking out through the gap between the shaft and the housing.

[0015] As a further improvement of the above solution, an installation column is sleeved inside the connecting column, and an annular groove is fixedly connected inside the installation column.

[0016] Through the above technical solution, the annular groove is installed through the installation column. The annular groove is installed between the first sealing lip and the second sealing lip. The annular groove is usually filled with grease, which plays a lubricating role, reducing the wear of the sealing ring caused by friction during operation and improving the sealing performance.

[0017] Compared with the prior art, the beneficial effects of the present utility model are as follows:

[0018] The utility model ensures that the oil seal can be tightly sleeved on the dehydration shaft by setting the sealing ring body, which is the main part of the oil seal and is usually in an annular structure with an inner diameter adapted to the outer diameter of the dehydration shaft of the washing machine. The outer diameter of the sealing ring body is slightly larger than the outer diameter of the dehydration shaft, which is convenient to provide a certain amount of compression during installation to ensure the sealing effect. An internal installation groove is opened inside it, and the dehydration shaft is sleeved in the internal installation groove. The device body and the washing machine are fixed through the skeleton fixed installation device, preventing it from falling off during use. The skeleton fixed installation device is clamped with the washing machine body through a clamping block, and there is a gap between the installation support rods, which is convenient for disassembly during installation.
