Abstract
Description
Technical Field
[0001] This utility model relates to the field of sealing components, and in particular to a rotatable sealing component. Background Technology
[0002] Seals are materials or parts used to prevent fluids or solid particles from leaking between adjacent mating surfaces and to prevent external impurities such as dust and moisture from entering the interior of machinery and equipment. Although small, rubber and plastic seals are essential components and accessories in major sectors of the national economy such as defense, chemical, petroleum, coal, transportation and machinery manufacturing, and are widely used in water pipes.
[0003] Chinese patent CN203161628U discloses a combination of a rotating ring assembly and a stationary ring assembly. The rotating ring assembly includes a rotating ring, a bellows, and a transmission sleeve. The rotating ring and the bellows are sealed together and fixed together by the transmission sleeve. The transmission sleeve is equipped with a positioning sleeve. The structure is simple and easy to use. It avoids uneven rolling during assembly, improves processing accuracy, and enhances sealing efficiency. However, the existing device still has some shortcomings. Existing seals are generally used in pipelines for connecting water pipes. However, existing seals can only achieve a fixed connection between two pipes and cannot meet the "angle adjustment" scenario in pipeline use. If forced rotation is performed, it can easily lead to damage to the sealing structure and cause fluid leakage. Therefore, we propose a rotatable seal to solve the above problems. Utility Model Content
[0004] The purpose of this invention is to provide a rotatable 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] A rotatable seal includes a rotating assembly, with mounting assemblies installed at both ends of the rotating assembly, a snap-fit assembly installed inside the rotating assembly, an extension assembly installed at the right end of the rotating assembly, and a connecting assembly sleeved on the outer surface of the extension assembly.
[0007] In a further embodiment, the rotating assembly includes a first sleeve and a second sleeve, the first sleeve being located on the outer surface of the second sleeve, an inner cylinder being installed inside the first sleeve, a threaded groove being provided at the right end of the inner cylinder, a sealed bearing being fitted on the outer surface of the inner cylinder, and the outer ring of the sealed bearing being connected to the inner wall of the second sleeve.
[0008] In a further embodiment, both of the mounting components include a first connecting plate, which is located at the left end of the first sleeve and the right end of the second sleeve, respectively. The outer surface of both first connecting plates is provided with a plurality of connecting holes, and a sealing gasket is installed on the side of the two first connecting plates that are far apart from each other.
[0009] In a further embodiment, the buckle assembly includes a slot and a rotating plate, the slot being located on the inner wall of the first sleeve, and the rotating plate being located at the left end of the second sleeve, the rotating plate being adapted to the slot.
[0010] In a further embodiment, the extension assembly includes a threaded sleeve located at the right end of the inner cylinder, and the right end of the threaded sleeve is connected to an extension tube.
[0011] In a further embodiment, the connecting assembly includes a connecting tube located on the outer surface of the extension tube, and a second connecting plate is mounted on the left end of the connecting tube.
[0012] Compared with the prior art, the beneficial effects of this utility model are:
[0013] This utility model discloses a rotatable seal. Through the sealing bearing of the rotating component and the double-layer sleeve structure, the relative rotation of the first sleeve and the second sleeve is achieved while ensuring no fluid leakage. This, in turn, drives the pipes connected at both ends to rotate, solving the problem that traditional seals can only be fixed and cannot rotate. It allows the pipes at both ends to rotate relative to each other, adapting to scenarios such as angle adjustment and position fine adjustment, and the sealing performance is not affected during the rotation process.

[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, a rotatable sealing component includes a rotating component 1, with mounting components 2 installed at both the left and right ends of the rotating component 1, a snap-fit component 5 installed inside the rotating component 1, an extension component 3 installed at the right end of the rotating component 1, and a connecting component 4 sleeved on the outer surface of the extension component 3.
[0023] The rotating assembly 1 includes a first sleeve 7 and a second sleeve 8. The first sleeve 7 is located on the outer surface of the second sleeve 8. An inner sleeve 12 is installed inside the first sleeve 7. A threaded groove 6 is formed at the right end of the inner sleeve 12. A sealed bearing 11 is fitted onto the outer surface of the inner sleeve 12. The outer ring of the sealed bearing 11 is connected to the inner wall of the second sleeve 8. Both the first sleeve 7 and the second sleeve 8 are made of metal, preferably stainless steel or a corrosion-resistant and high-strength metal. The first sleeve 7 is fitted onto the outer surface of the second sleeve 8, and the two are coaxially arranged to form a double-layer sleeve structure. The left end of the inner sleeve 12 is fixed to the inner wall of the first sleeve 7. The inner cylinder 12 has a fixed connection, with a fluid channel inside to meet pipeline transportation needs. The right end of the inner cylinder 12 has a threaded groove 6 for detachable connection with the extension component 3 via threads, which facilitates disassembly or replacement later. The sealing bearing 11 is a double-sided sealed deep groove ball bearing, which ensures flexible rotation between the inner cylinder 12 and the second sleeve 8, while preventing external dust and impurities from entering and preventing internal fluid from leaking from the rotation gap. The outer ring of the sealing bearing 11 is fixedly fitted with the inner wall of the second sleeve 8, so that the second sleeve 8 can rotate synchronously with the outer ring of the sealing bearing 11, thereby driving the connected external pipeline to rotate.
[0024] Both mounting components 2 include a first connecting plate 17, which is located at the left end of the first sleeve 7 and the right end of the second sleeve 8, respectively. Multiple connecting holes 18 are provided on the outer surface of both first connecting plates 17. Sealing gaskets 19 are installed on the side of the two first connecting plates 17 that are far apart from each other. The first connecting plate 17 is the connecting carrier between the sealing element and the external pipe. The sealing gasket 19 is squeezed and deformed to fill the connection gap, thereby achieving a seal at the interface and preventing fluid leakage.
[0025] The snap-fit assembly 5 includes a snap-fit groove 10 and a rotating snap-fit plate 9. The snap-fit groove 10 is located on the inner wall of the first sleeve 7, and the rotating snap-fit plate 9 is located at the left end of the second sleeve 8. The rotating snap-fit plate 9 is adapted to the snap-fit groove 10. The snap-fit groove 10 is an annular groove formed on the inner wall of the first sleeve 7. The rotating snap-fit plate 9 is an annular metal plate fixedly installed at the left end of the second sleeve 8. Its outer diameter is adapted to the inner diameter of the snap-fit groove 10 and can be embedded inside the snap-fit groove 10. The rotating snap-fit plate 9 and the snap-fit groove 10 are adapted to each other and form a sliding fit. This does not affect the rotation of the second sleeve 8 with the sealing bearing 11, and it can also limit the axial movement of the second sleeve 8, preventing the second sleeve 8 from shifting left or right during rotation and ensuring the overall structural stability of the rotating assembly 1.
[0026] The extension assembly 3 includes a threaded sleeve 13 located at the right end of the inner cylinder 12. The right end of the threaded sleeve 13 is connected to an extension tube 15. The connecting assembly 4 includes a connecting tube 16 located on the outer surface of the extension tube 15. A second connecting plate 14 is installed at the left end of the connecting tube 16. The extension tube 15 is made of a soft and wear-resistant material and can be bent. Inserting the extension tube 15 into the connecting tube 16 can extend the water flow and make the water flow smoother.
[0027] The working principle of this utility model is as follows:
[0028] In use, this rotatable seal first connects the flange of the discharge pipe to the first connecting plate 17 at the left end of the first sleeve 7, and installs the extension assembly 3 on the right end of the rotating assembly 1 through the threaded groove 6. Then, connects the first connecting plate 17 at the right end of the second sleeve 8 to the connecting assembly 4, so that the extension assembly 3 extends into the interior of the connecting assembly 4. At this time, the sealing gasket 19 is squeezed and deformed to achieve interface sealing. Then, when it is necessary to adjust the pipe angle, the second sleeve 8 is rotated, which drives the outer ring of the sealing bearing 11 to rotate. The inner cylinder 12 remains fixed with the first sleeve 7, realizing the relative rotation of the left and right pipes. During the rotation, the rotating plate 9 of the snap-fit assembly 5 slides synchronously in the snap-fit groove 10, limiting the axial displacement of the second sleeve 8 and preventing component displacement.
[0029] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention.
