Description

Technical Field

[0001] The embodiments disclosed herein relate to the field of oil seal technology, and more specifically, to a labyrinth-type dustproof and splashproof oil seal device. Background Technology

[0002] In many industrial sectors, such as machinery manufacturing, automotive engineering, and aerospace, sealing of rotating shafts or reciprocating motion components is a critical issue. During operation, these components need to prevent external dust, impurities, and splashing or leakage of the working medium to ensure the normal operation and service life of the equipment.

[0003] While traditional oil seal devices can achieve a certain degree of sealing, their sealing effect is often unsatisfactory in harsh working environments, such as dusty, high-humidity, or splash-prone situations. Ordinary lip seals are easily worn by the intrusion of dust particles, leading to a decrease in sealing performance and subsequent leakage of lubricating oil inside the equipment. This not only pollutes the working environment but may also cause equipment failure.

[0004] In addition, different equipment and application scenarios have different requirements for the specifications and installation methods of oil seal devices. Some existing oil seal devices have poor versatility and are difficult to meet the connection requirements of multiple specifications, which increases the cost and difficulty of equipment maintenance and oil seal replacement. Utility Model Content

[0035] like Figures 1-4 As shown, it illustrates the labyrinth-type dust and splash-proof oil seal device of this disclosure, comprising:

[0036] Connecting ring 1, the lower end of which is provided with a connecting cavity 2;

[0037] A collection and cleaning component 3 is disposed on the connecting ring 1;

[0038] A multi-specification connection component 4 is disposed within the connection cavity 2;

[0039] The collection and cleaning component 3 includes a connecting jacket 3-1, which is disposed on the outer side wall of the connecting ring 1. The inner side wall of the connecting jacket 3-1 is provided with a fitting ring 3-2. The lower end face of the fitting ring 3-2 is provided with an arc-shaped intercepting plate 3-3. The outer side wall of the connecting ring 1 is provided with an inclined guide plate 3-4. A closing plate 3-5 is provided on the inclined guide plate 3-4. The closing plate 3-5 and the arc-shaped intercepting plate 3-3 are spliced ​​and fitted together.

[0040] The multi-specification connecting assembly 4 includes a splicing ring 4-1, the upper end face of which is provided with a insertion groove 4-2, and a threaded ring 4-3 is provided in the insertion groove 4-2. The upper end face of the connecting cavity 2 is provided with a meshing cavity 4-4, and the threaded ring 4-3 is screwed into the meshing cavity 4-4.

[0041] In some examples, the connecting jacket 3-1 is fitted onto the outer wall of the connecting ring 1, so that the fitting ring 3-2 fits against the outer wall of the connecting ring 1, and the arc-shaped intercepting plate 3-3 is spliced ​​and fitted with the closed plate 3-5 on the inclined guide plate 3-4, with the ends of the two contacting each other.

[0042] Tighten the threaded ring 4-3 on the splicing ring 4-1 into the meshing cavity 4-4 on the upper end face of the connecting cavity 2.

[0043] like Figures 1-4 As shown, in this embodiment, the outer side wall of the connecting jacket 3-1 is provided with cleaning holes 3-6, and the number of cleaning holes 3-6 is several, with multiple cleaning holes 3-6 evenly distributed on the side wall of the connecting jacket 3-1.

[0044] In some examples, the cleaning hole 3-6 is connected to the connecting sleeve 3-1. After inserting a tube into the cleaning hole 3-6, the tube connects the arc-shaped intercepting plate 3-3 and the closing plate 3-5, allowing the arc-shaped intercepting plate 3-3 and the closing plate 3-5 to open and close, so that the waste liquid can be discharged.

[0045] For example, such as Figures 1-4 As shown, there are several insertion slots 4-2, each with a different diameter. These insertion slots 4-2 are formed on the connecting ring 1. The number of meshing cavities 4-4 is the same as the number of insertion slots 4-2, and the positions of the insertion slots 4-2 and meshing cavities 4-4 correspond to each other.

[0046] For example, such as Figure 2 As shown, the upper end face of the connecting ring 1 is provided with a fitting pad 5, and the upper end face of the connecting sleeve 3-1 is provided with a sealing pad 6. Both the fitting pad 5 and the sealing pad 6 are circular structures.

[0047] In some examples, the sealing gasket 6 on the upper surface of the connecting jacket 3-1 is in close contact with the fitting gasket 5 on the upper surface of the connecting ring 1 to enhance the sealing effect.

[0048] For example, such as Figure 4 As shown, a splicing pad 7 is provided on the upper end face of the splicing ring 4-1, and the splicing pad 7 is sealed and fitted with the connecting cavity 2.

[0049] In some examples, during the tightening process, the splicing pad 7 on the upper surface of the splicing ring 4-1 is ensured to fit tightly against the connecting cavity 2, thus providing a sealing effect.

[0050] For example, such as Figure 4 As shown, the inner sidewall of the connecting ring 1 is provided with a meshing groove 8, and the inside of the meshing groove 8 is provided with a meshing thread 10.

[0051] In some examples, the engagement groove 8 is used to install the engagement thread 10, and the connecting ring 1 is screwed into the engagement cavity 4-4 through the engagement thread 10, so that the connecting ring 1 is embedded in the connecting cavity 2.

[0052] For example, such as Figure 2 As shown, the cleaning hole 3-6 is inclined, and the inclination angle of the cleaning hole 3-6 is parallel to that of the inclined guide plate 3-4.

[0053] For example, such as Figure 4 As shown, the lower end of the threaded ring 4-3 is provided with a connector strip 9, which is inserted into the interior of the connector groove 4-2. The arc-shaped intercepting piece 3-3 and the closing piece 3-5 are both arc-shaped structures made of hard rubber, and the end of the arc-shaped intercepting piece 3-3 is in contact with the end of the closing piece 3-5.

[0054] In some examples, the insert strip 9 at the lower end of the threaded ring 4-3 is aligned with the insert groove 4-2 on the upper end face of the splicing ring 4-1 and inserted to complete the initial positioning.

[0055] When the device is in use and working normally, external dust and splashes are first blocked by the arc-shaped interceptor plate 3-3. The cleaning hole 3-6 is connected to the connecting sleeve 3-1. After inserting the tube into the cleaning hole 3-6, the arc-shaped interceptor plate 3-3 and the closing plate 3-5 are opened and closed through the tube, so that the waste liquid is discharged. Some impurities that cross the arc-shaped interceptor plate 3-3 will be guided by the inclined guide plate 3-4 and flow along the inclined direction. During the flow, the impurities will be blocked again by the closing plate 3-5 and the arc-shaped interceptor plate 3-3, and finally flow along the inclined guide plate 3-4 to the cleaning hole 3-6.

[0056] The connecting ring inside the connecting cavity can be replaced with threaded rings of different diameters according to actual usage requirements.

[0057] It should be noted that the above embodiments are only used to illustrate the technical solutions of this disclosure and are not intended to limit it. Although this disclosure has been described in detail with reference to preferred embodiments, those skilled in the art should understand that modifications or equivalent substitutions can be made to the technical solutions of this disclosure without departing from the spirit and scope of the technical solutions of this disclosure, and all such modifications and substitutions should be covered within the scope of the claims of this disclosure.
