Description

Technical Field

[0001] This utility model relates to the field of sealing technology, and in particular to an antifreeze oil seal. Background Technology

[0002] A seal is a component used to prevent liquid or gas from leaking between adjacent mating surfaces. Its main function is to prevent external impurities such as dust and moisture from entering the interior of machinery and equipment. Seals are widely used in various mechanical equipment and are known as the "guardians" of industrial equipment. An oil seal is a sealing element used to seal the rotating shaft in mechanical equipment. Its main function is to prevent lubricating oil from leaking from the gaps in the mechanical equipment, while also preventing the intrusion of external impurities such as water, chemical solutions, dust, and sand. Oil seals are usually installed on rotating shafts and, through their special structure and materials, ensure that the sealing effect is maintained during the operation of the machinery.

[0003] Existing oil seals suffer from poor sealing performance and are unsuitable for use because the movement of the transmission parts causes the oil seal body to move during operation. Furthermore, in cold winter weather, the lubricant is prone to freezing, affecting engine operation. Therefore, we propose an antifreeze oil seal to solve the above problems. Summary of the Invention

[0004] The purpose of this utility model is to provide an antifreeze oil seal to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] An antifreeze oil seal includes a first sealing ring, a second sealing ring on the outer surface of the first sealing ring, an installation groove on the outer surface of the first sealing ring, a rubber band inside the installation groove, a symmetrical annular block fixedly connected to the outer surface of the first sealing ring, and a symmetrical annular groove inside the second sealing ring, the interior of the two annular grooves being movably connected to the outer surfaces of the two annular blocks.

[0007] In a further embodiment, an antifreeze layer is fixedly connected to the outer surface of the second sealing ring.

[0008] In a further embodiment, a wear-resistant layer is fixedly connected to the outer surface of the antifreeze layer, and the wear-resistant layer is a stainless steel ring.

[0009] In a further embodiment, the outer surface of the wear-resistant layer has several notches.

[0010] In a further embodiment, a connecting rod is fixedly connected inside each of the recesses.

[0011] In a further embodiment, both the first sealing ring and the second sealing ring are rubber sealing rings.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This device uses a first sealing ring, a mounting groove, and a rubber band to install the rubber band into the mounting groove. The elasticity of the rubber band strengthens the bond between the first sealing ring and the transmission component, thus solving the problem of poor sealing caused by the movement of the transmission component driving the oil seal body. The second sealing ring, annular block, and annular groove work together to install the second sealing ring onto the first sealing ring, protecting the rubber band. An antifreeze layer is also included to insulate the entire device, preventing the lubricant from freezing in cold weather and affecting engine operation, thus rendering it unusable.

[0019] In the description of this utility model, it should be understood that the terms "center," "longitudinal," "lateral," "upper," "lower," "front," "rear," "left," "right," "vertical," "horizontal," "top," "bottom," "inner," and "outer," etc., indicating orientation or positional relationships based on the orientation or positional relationships shown in the accompanying drawings, are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation of this utility model. Furthermore, the terms "first," "second," etc., are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of indicated technical features. Thus, features defined with "first," "second," etc., may explicitly or implicitly include one or more of that feature. In the description of this utility model, unless otherwise stated, "a plurality of" means two or more.

[0020] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installation," "connection," and "joining" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium; and they can refer to the internal connection of two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0021] 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.

[0022] Please see Figure 1-4 In this utility model, an antifreeze oil seal includes a first sealing ring 1, a second sealing ring 2 on the outer surface of the first sealing ring 1, an installation groove 3 on the outer surface of the first sealing ring 1, a rubber band 4 inside the installation groove 3, and symmetrical annular blocks 5 fixedly connected to the outer surface of the first sealing ring 1. Symmetrical annular grooves 8 are opened inside the second sealing ring 2, and the interiors of the two annular grooves 8 are movably connected to the outer surfaces of the two annular blocks 5. Through the cooperation of the first sealing ring 1, the installation groove 3, and the rubber band 4, the positioning of the first sealing ring 1 can be enhanced, thereby solving the problem that when the transmission part moves, it drives the oil seal body to move, resulting in poor sealing effect. Through the cooperation of the second sealing ring 2, the annular blocks 5, and the annular grooves 8, the rubber band 4 can be protected, thereby extending the service life of the rubber band 4.

[0023] An antifreeze layer 6 is fixedly connected to the outer surface of the second sealing ring 2, and a wear-resistant layer 7 is fixedly connected to the outer surface of the antifreeze layer 6. The wear-resistant layer 7 is a stainless steel ring. By setting the antifreeze layer 6, the whole unit can be kept warm, preventing the lubricant from freezing in cold weather, which would affect the operation of the engine and make it unusable. By setting the wear-resistant layer 7, high wear resistance can be provided, thereby improving the service life of this device.

[0024] The outer surface of the wear-resistant layer 7 has several recesses 9, and a connecting rod 10 is fixedly connected inside each recess 9. The first sealing ring 1 and the second sealing ring 2 are both rubber sealing rings. By providing recesses 9, the material used in the wear-resistant layer 7 can be reduced, thereby reducing costs. By providing connecting rods 10, the load-bearing capacity of the wear-resistant layer 7 can be enhanced. By providing first sealing ring 1 and second sealing ring 2 as rubber sealing rings, good sealing performance can be improved, ensuring that there are no gaps at the connection parts.

[0025] The working principle of this utility model is as follows:

[0026] During use, the first sealing ring 1 is installed onto the shaft column, and then the rubber band 4 is installed into the mounting groove 3 to strengthen the first sealing ring 1. Then, through the cooperation of the annular block 5 and the annular groove 8, the second sealing ring 2 is installed onto the first sealing ring 1, which protects the rubber band 4. The antifreeze layer 6 can keep the whole unit warm, preventing the lubricant from freezing in cold weather, which would affect the operation of the engine and make it unusable. The wear-resistant layer 7 can increase the overall service life.
