[0002] Mechanical seals play a vital role in many industrial sectors. They are widely used in various equipment that transports media (such as liquids and gases) to prevent media leakage and ensure the safe, stable and efficient operation of the equipment.

[0003] Traditional mechanical seal devices often employ relatively fixed and complex connection methods, relying heavily on bolt fastening, nested structures, and lacking convenient movable connection designs between components. When maintenance and repair require disassembling and assembling the mechanical seal device, workers often face numerous difficulties. Due to the complex connection structure, disassembly requires a significant amount of time to accurately locate each connection point and disassemble sequentially. This not only increases the labor costs of equipment maintenance but also prolongs equipment downtime due to the extended disassembly and assembly time, affecting the continuity of the entire production process and causing substantial economic losses to the enterprise.

[0004] Therefore, there is an urgent need for a mechanical seal device that is easy to install and disassemble to solve the above problems. Utility Model Content

[0005] The purpose of this invention is to provide a mechanical seal device that is easy to assemble and disassemble, so as to solve the problems mentioned in the background art.

[0006] To achieve the above-mentioned objectives, this utility model provides the following technical solution:

[0007] A mechanical seal device that is easy to assemble and disassemble includes a rotating ring seat, a spring seat fixedly connected to the inner wall of the rotating ring seat, and a strong spring fixedly connected to the outer wall of the spring seat, and further includes:

[0008] A rotating connection assembly includes a stationary ring seat slidably connected to the outer wall of a moving ring seat. A uniformly distributed rotating rod is rotatably connected to the inner wall of the stationary ring seat. A gear is fixedly connected to the outer wall of the rotating rod. A uniformly distributed toothed plate is slidably connected to the inner wall of the stationary ring seat, and the outer wall of the toothed plate meshes with the outer wall of the gear. A limit block is fixedly connected to the outer wall of the toothed plate. A connecting cover plate is slidably connected to the limit block through a limit groove. A uniformly distributed anti-rotation block is fixedly connected to the outer wall of the connecting cover plate. A limit assembly is provided on the inner wall of the rotating rod at the top.

[0009] The ring seal is located between the moving ring seat and the stationary ring seat;

[0010] The drive component is located on the outer wall of the moving ring seat.

[0011] As a preferred technical solution of this application, the limiting component includes a hexagonal rod slidably connected to the inner wall of the rotating rod, and the hexagonal rod is slidably connected to the stationary ring seat. A pulling block is fixedly connected to the outer wall of the hexagonal rod, and a strong tension spring is sleeved on the outer wall of the hexagonal rod. The strong tension spring is fixedly connected to the pulling block, and the end of the strong tension spring away from the pulling block is fixedly connected to the stationary ring seat.

[0012] As a preferred technical solution of this application, the drive assembly includes an extension seat fixedly connected to the outer wall of the moving ring seat, an internal gear ring fixedly connected to the inner wall of the extension seat, and the outer wall of the internal gear ring meshing with the outer wall of the gear.

[0013] As a preferred technical solution of this application, the inner wall of the stationary ring seat is provided with a stationary ring body, and a stationary ring auxiliary sealing ring is provided between the stationary ring seat, the stationary ring body and the connecting cover plate, and the outer wall of the stationary ring auxiliary sealing ring abuts against the outer wall of the anti-rotation block. The outer wall of the stationary ring body is provided with a moving ring body, and the outer wall of the moving ring body abuts against the outer wall of the strong spring.

[0014] As a preferred technical solution of this application, the inner wall of the moving ring body is provided with a moving ring auxiliary sealing ring, the inner wall of the moving ring auxiliary sealing ring is provided with a rotating shaft, and the outer wall of the rotating shaft abuts against the outer wall of the moving ring auxiliary sealing ring.

[0015] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0016] In the scheme of this application:

[0017] By setting up a unique rotating connection component, and utilizing the cooperation of rotating rods, gears, toothed plates, limiting components, and drive components, disassembly and assembly can be performed simply by operating the pulling block of the limiting component to release the limit on the top rotating rod, and then rotating its moving ring seat to drive the limiting rod into the limiting groove. After that, releasing the pulling block completes the connection and assembly. Conversely, the moving ring seat and the stationary ring seat can be disassembled, easily realizing the disassembly and assembly of the device without complicated tools and long-term exploration. This saves disassembly and assembly time, reduces labor costs, and improves the efficiency of equipment maintenance and repair. It is especially suitable for disassembly and assembly needs in complex working conditions such as limited equipment space. It solves the problem that in the existing technology, a lot of time is required to accurately locate each connection point and disassemble them one by one. This not only increases the labor costs of equipment maintenance, but also prolongs the equipment downtime due to the long disassembly and assembly time, affecting the continuity of the entire production process and causing significant economic losses to enterprises.

[0027] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model.

[0028] like Figure 1-7 As shown, the mechanical seal device proposed in this embodiment, which is easy to assemble and disassemble, includes a rotating ring seat 1, a spring seat 6 fixedly connected to the inner wall of the rotating ring seat 1, and a strong spring 7 fixedly connected to the outer wall of the spring seat 6. It also includes:

[0029] The rotating connection assembly includes a stationary ring seat 2 slidably connected to the outer wall of the moving ring seat 1. A uniformly distributed rotating rod 12 is rotatably connected to the inner wall of the stationary ring seat 2. A gear 13 is fixedly connected to the outer wall of the rotating rod 12. A uniformly distributed toothed plate 14 is slidably connected to the inner wall of the stationary ring seat 2, and the outer wall of the toothed plate 14 meshes with the outer wall of the gear 13. A limiting block 21 is fixedly connected to the outer wall of the toothed plate 14. A connecting cover plate 3 is slidably connected to the limiting block 21 through a limiting groove 19. The outer wall is fixedly connected with uniformly distributed anti-rotation blocks 18. A limit component is set on the inner wall of the top rotating rod 12. The gear 13 meshes with the transmission gear plate 14 to slide in the stationary ring seat 2, thereby realizing the limit block 21 sliding into the limit groove 19, that is, realizing the limit fixation of the connecting cover plate 3. The outer wall of the limit block 21 and the inner wall of the limit groove 19 both have inclined surfaces, so the deeper the limit block 21 goes into the limit groove 19, the stronger the connection between the connecting cover plate 3 and the stationary ring seat 2 and the moving ring seat 1.

[0030] The ring seal 9 is disposed between the moving ring seat 1 and the stationary ring seat 2. The ring seal 9 plays a preliminary sealing role to prevent the medium from leaking between the two.

[0031] The drive component is located on the outer wall of the moving ring seat 1.

[0032] like Figure 7 As shown, in a preferred embodiment, based on the above method, the limiting component further includes a hexagonal rod 20 slidably connected to the inner wall of the rotating rod 12, and the hexagonal rod 20 is slidably connected to the stationary ring seat 2. A pulling block 10 is fixedly connected to the outer wall of the hexagonal rod 20, and a strong tension spring 22 is sleeved on the outer wall of the hexagonal rod 20. The strong tension spring 22 is fixedly connected to the pulling block 10, and the end of the strong tension spring 22 away from the pulling block 10 is fixedly connected to the stationary ring seat 2. When the limiting component located on the inner wall of the top rotating rod 12 is operated, the pulling block 10 is pulled, causing the hexagonal rod 20 to slide on the inner wall of the rotating rod 12. At this time, the strong tension spring 22 is stretched, so that the rotating rod 12 can rotate in the stationary ring seat 2, that is, the gear 13 can rotate, ensuring the correlation and stability of each component during the rotation process.

[0033] like Figure 3-4 As shown, in a preferred embodiment, based on the above method, the driving component further includes an extension seat 5 fixedly connected to the outer wall of the moving ring seat 1. An internal gear ring 15 is fixedly connected to the inner wall of the extension seat 5, and the outer wall of the internal gear ring 15 meshes with the outer wall of the gear 13. Rotating the moving ring seat 1 causes the extension seat 5 to rotate, which in turn drives the internal gear ring 15 to rotate, and the internal gear ring 15 meshes with the transmission gear 13 to rotate.

[0034] like Figure 3As shown, in a preferred embodiment, based on the above method, a stationary ring body 16 is further provided on the inner wall of the stationary ring seat 2. A stationary ring auxiliary sealing ring 17 is provided between the stationary ring seat 2, the stationary ring body 16 and the connecting cover plate 3, and the outer wall of the stationary ring auxiliary sealing ring 17 abuts against the outer wall of the anti-rotation block 18. A rotating ring body 8 is provided on the outer wall of the stationary ring body 16, and the outer wall of the rotating ring body 8 abuts against the outer wall of the strong spring 7. The stationary ring auxiliary sealing ring 17 further enhances the sealing effect. The rotating ring body 8 is tightly fitted with the stationary ring body 16 under the elastic force of the strong spring 7. The anti-rotation block 18 abuts against the stationary ring auxiliary sealing ring 17 to prevent the stationary ring auxiliary sealing ring 17 from rotating.

[0035] like Figure 3 As shown, in a preferred embodiment, based on the above method, a dynamic ring auxiliary sealing ring 11 is further provided on the inner wall of the dynamic ring body 8, and a rotating shaft 4 is provided on the inner wall of the dynamic ring auxiliary sealing ring 11. The outer wall of the rotating shaft 4 abuts against the outer wall of the dynamic ring auxiliary sealing ring 11, and dynamic sealing is achieved through the dynamic ring auxiliary sealing ring 11.

[0036] Specifically, in use, this easily disassembled mechanical seal device works as follows: When the limiting component located on the inner wall of the top rotating rod 12 is operated, pulling the pulling block 10 causes the hexagonal rod 20 to slide on the inner wall of the rotating rod 12. At this time, the strong tension spring 22 is stretched, allowing the rotating rod 12 to rotate within the stationary ring seat 2, that is, the gear 13 can rotate. Then, rotating its moving ring seat 1 causes the extension seat 5 to rotate, which in turn causes the internal gear ring 15 to rotate. The internal gear ring 15 meshes with the transmission gear 13, and further, the gear 13 meshes with the transmission gear plate 14 to slide within the stationary ring seat 2, thereby allowing the limiting block 21 to slide into the limiting position. Within the groove 19, the connecting cover plate 3 is fixed and positioned. Both the outer wall of the limiting block 21 and the inner wall of the limiting groove 19 have inclined surfaces. Therefore, the deeper the limiting block 21 is into the limiting groove 19, the stronger the connection between the connecting cover plate 3, the stationary ring seat 2, and the moving ring seat 1. Finally, the pulling block 10 is released, and the strong tension spring 22 pulls the pulling block 10 and the hexagonal rod 20 towards the stationary ring seat 2. The hexagonal rod 20 is used to fix and position the rotating rod 12, thus maintaining the meshing and static state between the gear 13, the toothed plate 14, and the internal toothed ring 15, ensuring the correlation and stability of each component during rotation. Otherwise, disassembly can be performed.

[0037] The above embodiments are only used to illustrate the present utility model and are not intended to limit the technical solutions described in the present utility model. Although the present utility model has been described in detail with reference to the above embodiments, the present utility model is not limited to the specific embodiments described above. Therefore, any modifications or equivalent substitutions to the present utility model, and all technical solutions and improvements that do not depart from the spirit and scope of the invention, are covered within the scope of the claims of the present utility model.
