Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, and more specifically, to an easily detachable sealing ring. Background Art

[0002] Sealing rings are circular or ring-shaped parts used to fill, seal or isolate objects. However, in existing sealing rings, since the sealing rings are tightly installed inside the sealing groove for a long time, when the equipment or the output shaft connected to the sealing ring moves for a long time and rubs against the sealing ring, a large amount of heat will be generated. This heat will heat the sealing ring, making it easy for the sealing ring to lose its elastic properties, resulting in a significant reduction in its service life. Utility Model Content

[0003] In order to overcome the deficiencies of the prior art, the utility model provides an easily detachable sealing ring, which has the advantages of reducing frictional heat of the sealing ring and increasing service life.

[0004] To achieve the above-mentioned purpose, the present invention provides the following technical solutions: an easily removable sealing ring, comprising a sealing ring, wherein an inner ring layer and an outer ring layer are fixedly installed at the bottom of the sealing ring, the diameter of the inner ring layer is greater than the diameter of the outer ring layer, a sealing layer is fixedly installed on the outside of the inner ring layer, the sealing layer is located on the inner side of the outer ring layer and is fixedly connected to the outer ring layer, the sealing layer is located at the bottom of the sealing ring, an oil outlet hole 1 is fixedly installed inside the sealing layer, and an oil outlet hole 2 is opened inside the inner ring layer.

[0005] As an optimal technical solution of the present invention, a hidden groove and a connecting hole are provided inside the sealing ring, a connecting shaft is provided inside the connecting hole, a fixing sleeve is sleeved on the outside of the connecting shaft, and a handle is fixedly installed on the outside of the fixing sleeve.

[0006] As an optimal technical solution of the present invention, the diameter of the inner ring layer is smaller than the diameter of the outer ring layer, there are multiple oil outlet holes 2, and the multiple oil outlet holes 2 are all located on the inner side of the inner ring layer, and the multiple oil outlet holes 2 are all connected to the sealing layer.

[0007] As a preferred technical solution of the present invention, there are two handles, both of which are located inside the hidden groove, and the two handles are distributed in opposite directions, and the material of the two handles is the same as that of the sealing ring.

[0008] As a preferred technical solution of the present invention, a limit strip is fixedly installed on the upper part of the hidden groove. There are two limit strips, both of which are located inside the sealing ring and above the handle.

[0009] As a preferred technical solution of the present invention, there are multiple oil outlet holes 1, and the multiple oil outlet holes 1 are all located inside the sealing layer, and the multiple oil outlet holes 1 are surrounded by two circles.

[0010] Compared with the prior art, the beneficial effects of the present invention are as follows:

[0011] 1. The utility model has an inner ring layer and an outer ring layer fixedly installed on the bottom of the sealing ring, a sealing layer fixedly installed between the inner ring layer and the outer ring layer, and a second oil outlet hole is opened on the inner side of the inner ring layer. After the sealing ring is installed inside the equipment, the output shaft of the equipment is inserted into the inner side of the sealing ring to make the sealing ring seal it. At this time, since the sealing ring and the sealing layer are filled with lubricating oil, the lubricating oil will flow into the intersection of the sealing ring and the output shaft along the second oil outlet hole, thereby reducing the friction between the sealing ring and the output shaft and achieving the effect of reducing heat. Since the opening of the second oil outlet hole is small and the outflow speed is slow, most of the lubricating oil will remain inside the sealing ring and the sealing layer, thereby absorbing the heat of the sealing ring, accelerating the cooling effect of the sealing ring, and preventing the elastic performance of the sealing ring from disappearing after high heat, thereby improving the service life of the sealing ring.

[0012] 2. The utility model has a hidden groove and a connecting hole opened inside the sealing ring, a connecting shaft provided inside the connecting hole, a fixed sleeve sleeved on the outer side of the connecting shaft, and a handle fixedly installed on the outer side of the fixed sleeve. When the sealing ring needs to be disassembled, repaired or replaced, the handle is rotated around the connecting shaft through the fixed sleeve and pulled upward, so that the sealing ring can be directly pulled out. At the same time, since the material of the handle is the same as that of the sealing ring, it is convenient to disassemble without affecting the normal use of the sealing ring.

[0020] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the embodiments described are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts are within the scope of protection of the present invention.

[0021] like Figures 1 to 6 As shown, the utility model provides an easily removable sealing ring, including a sealing ring 1, an inner ring layer 7 and an outer ring layer 8 are fixedly installed on the bottom of the sealing ring 1, the diameter of the inner ring layer 7 is larger than the diameter of the outer ring layer 8, a sealing layer 9 is fixedly installed on the outside of the inner ring layer 7, the sealing layer 9 is located on the inner side of the outer ring layer 8 and is fixedly connected to the outer ring layer 8, the sealing layer 9 is located at the bottom of the sealing ring 1, an oil outlet hole 10 is fixedly installed inside the sealing layer 9, and an oil outlet hole 2 11 is opened inside the inner ring layer 7.

[0022] There is a large amount of lubricating oil between the sealing layer 9 and the sealing ring 1. When the sealing ring 1 is installed inside the equipment, the output shaft rubs and squeezes the inner ring 7, which can make the lubricating oil between the sealing layer 9 and the sealing ring 1 slowly flow out through the oil outlet hole 11, reducing the friction between the sealing ring 1 and the output shaft, thereby reducing heat.

[0023] The sealing ring 1 has a hidden groove 2 and a connecting hole 3 formed inside. The connecting hole 3 has a connecting shaft 4 formed inside. A fixing sleeve 5 is sleeved on the outside of the connecting shaft 4. A handle 6 is fixedly installed on the outside of the fixing sleeve 5.

[0024] The fixing sleeve 5 is rotatably connected to the connecting shaft 4, which can drive the handle 6 to rotate, so that the handle 6 is rotated to be perpendicular to the sealing ring 1, thereby achieving the effect of facilitating the disassembly of the sealing ring 1.

[0025] Among them, the diameter value of the inner ring layer 7 is smaller than the diameter value of the outer ring layer 8, there are multiple oil outlet holes 11, and the multiple oil outlet holes 11 are all located on the inner side of the inner ring layer 7, and the multiple oil outlet holes 11 are all connected to the sealing layer 9.

[0026] The main function of the plurality of oil outlet holes 11 is to facilitate the flow of lubricating oil into the surface of the output shaft. Since the opening of the oil outlet holes 11 is small and the outflow speed is slow, most of the lubricating oil will remain inside the sealing ring 1 and the sealing layer 9, thereby absorbing the heat of the sealing ring 1, accelerating the cooling effect of the sealing ring 1, and preventing the elastic properties of the sealing ring 1 from disappearing after high heat.

[0027] There are two handles 6 , both of which are located inside the hidden groove 2 , and the two handles 6 are distributed in opposite directions, and the material of the two handles 6 is the same as that of the sealing ring 1 .

[0028] The two handles 6 have a certain degree of elasticity. When they are not needed, they can be stored inside the hidden groove 2 without affecting the normal sealing and use of the sealing ring 1.

[0029] Among them, a limit strip 12 is fixedly installed on the upper part of the hidden groove 2. There are two limit strips 12. Both limit strips 12 are located inside the sealing ring 1 and both limit strips 12 are located above the handle 6.

[0030] The main function of the two limit bars 12 is to limit the handle 6 when it is not needed, so as to prevent the handle 6 from shaking and affecting the normal use of the device.

[0031] There are multiple oil outlet holes 10 , all of which are located inside the sealing layer 9 , and the multiple oil outlet holes 10 are arranged in two circles.

[0032] The main function of the multiple oil outlet holes 10 is to increase some lubricating oil between the sealing ring 1 and the sealing groove, thereby reducing the lubrication between the sealing ring 1 and the sealing groove, and preventing the sealing ring 1 from being too dry and thus prone to hardening.

[0033] The working principle and use process of this utility model:

[0034] First, install the sealing ring 1 into the sealing groove reserved for the equipment, and insert the output shaft of the equipment into the sealing ring 1 so that the output shaft contacts the inner side of the sealing ring 1 to achieve the sealing effect of the sealing ring 1 and the output shaft;

[0035] Secondly, an inner ring layer 7 and an outer ring layer 8 are fixedly installed at the bottom of the sealing ring 1, and a sealing layer 9 is fixedly installed between the inner ring layer 7 and the outer ring layer 8. At the same time, a second oil outlet hole 11 is opened on the inner side of the inner ring layer 7. Since the sealing ring 1 and the sealing layer 9 are filled with lubricating oil, the lubricating oil will flow into the intersection of the sealing ring 1 and the output shaft along the second oil outlet hole 11, thereby reducing the friction between the sealing ring 1 and the output shaft and achieving the effect of reducing heat. Since the opening of the second oil outlet hole 11 is small and the outflow speed is slow, most of the lubricating oil will remain in the sealing ring 1 and the sealing layer 9, thereby absorbing the heat of the sealing ring 1, accelerating the cooling effect of the sealing ring 1, and preventing the elastic performance of the sealing ring 1 from disappearing after high heat;

[0036] Finally, a hidden groove 2 and a connecting hole 3 are provided inside the sealing ring 1, a connecting shaft 4 is provided inside the connecting hole 3, a fixing sleeve 5 is sleeved on the outside of the connecting shaft 4, and a handle 6 is fixedly installed on the outside of the fixing sleeve 5. When the sealing ring 1 needs to be disassembled, repaired or replaced, the handle 6 is rotated around the connecting shaft 4 through the fixing sleeve 5 and the handle 6 is pulled upward, so that the sealing ring 1 can be directly pulled out, achieving the effect of convenient disassembly. At the same time, since the material of the handle 6 is the same as that of the sealing ring 1, it can be easily disassembled without affecting the normal use of the sealing ring 1.
