[0023] The technical solutions in the embodiments of the present application will be clearly and completely described below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, rather than all the embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor fall within the scope of protection of the present application.

[0024] Embodiment 1: Please refer to Figures 1-5 The present application provides a kind of anti-deformation rubber sealing element, including upper connecting ring 2 and lower connecting ring 3, upper connecting ring 2 and lower connecting ring 3 are all installed with sealing ring 1, sealing ring 1 is composed of sealing gasket 11 and mounting ring 12, the outside of upper connecting ring 2 is fixedly connected with upper support ring 21, upper installation groove 22 is set between upper support ring 21 and upper connecting ring 2, the outside of lower connecting ring 3 is fixedly connected with lower support ring 33, lower installation groove 32 is set between lower support ring 33 and lower connecting ring 3, upper installation groove 22 and lower installation groove 32 are all adapted with mounting ring 12, the inner wall of lower connecting ring 3 is provided with helical groove 31, the bottom outside of upper connecting ring 2 is provided with helical thread 23, upper connecting ring 2 is helically installed in helical groove 31 by the helical thread 23 of its bottom;

[0025] The bottom of upper support ring 21 and the outside of upper installation groove 22 are annularly arrayed with first reinforcing rib 25 between them;

[0026] The bottom of upper installation groove 22 and the outside of upper connecting ring 2 are annularly arrayed with second reinforcing rib 26 between them;

[0027] The top of lower support ring 33 and the outside of lower installation groove 32 are annularly arrayed with third reinforcing rib 37 between them.

[0028] Specifically, the sealing ring 1 composed of the sealing gasket 11 and the mounting ring 12 is respectively mounted on the upper connecting ring 2 and the lower connecting ring 3. Specifically, the mounting ring 12 is correspondingly embedded in the upper mounting groove 22 of the upper connecting ring 2 and the lower mounting groove 32 of the lower connecting ring 3. Since the upper mounting groove 22 and the lower mounting groove 32 are both matched with the mounting ring 12, the mounting ring 12 can be smoothly embedded in the mounting groove without excessive force to pry open the sealing ring 1 for installation, reducing the possibility of deformation of the sealing ring 1 caused by installation operation. The helical thread 23 on the outer side of the bottom of the upper connecting ring 2 is helically installed in the helical groove 31 on the inner wall of the lower connecting ring 3. By rotating the upper connecting ring 2, it is rotated into the helical groove 31, realizing the close connection of the upper connecting ring 2 and the lower connecting ring 3.

[0029] The upper support ring 21 and the upper connecting ring 2, and the lower support ring 33 and the lower connecting ring 3 are provided to support the sealing ring 1. At the same time, the first reinforcing rib 25, the second reinforcing rib 26 and the third reinforcing rib 37 further enhance the connection strength between the components. The first reinforcing rib 25 enhances the connection between the upper support ring 21 and the outer side of the upper mounting groove 22, the second reinforcing rib 26 enhances the connection between the upper mounting groove 22 and the outer side of the upper connecting ring 2, and the third reinforcing rib 37 enhances the connection between the lower support ring 33 and the outer side of the lower mounting groove 32. These reinforcing ribs make the entire sealing structure more stable. When the sealing is stressed, the first reinforcing rib 25, the second reinforcing rib 26 and the third reinforcing rib 37 can evenly distribute stress to each component, avoiding stress concentration in some weak parts, bearing greater pressure and external force, reducing the possibility of deformation and prolonging the service life.

[0030] Further, in order to ensure stable connection, please refer to Figures 1-5 A limiting groove 24 is vertically provided in the helical thread 23, and the limiting groove 24 is equidistantly arranged on the lateral side of the upper connecting ring 2.

[0031] A moving groove 34 is provided on the lower connecting ring 3, and a helical rod 35 is helically connected to one end of the moving groove 34. A limiting block 36 is fixedly arranged on one end of the helical rod 35, and the diameter of the limiting block 36 is matched with the width of the limiting groove 24.

[0032] Specifically, when installing, the upper connecting ring 2 is rotated and rotated into the helical groove 31. This helical connection itself has a certain self-locking property. In the normal use process, the friction between the helical thread 23 and the helical groove 31 can prevent the upper connecting ring 2 and the lower connecting ring 3 from easily rotating or separating relative to each other, providing basic stability for the connection of the entire sealing.

[0033] When the upper connecting ring 2 and the lower connecting ring 3 are installed, after the helical thread 23 is screwed into the helical groove 31 to a certain position, the limiting block 36 can be moved along the moving groove 34 and clamped into the corresponding limiting groove 24 by rotating the helical rod 35. After the limiting block 36 is clamped into the limiting groove 24, relative rotation between the upper connecting ring 2 and the lower connecting ring 3 due to factors such as vibration and external force impact during use can be effectively prevented. Even when subjected to a certain external force, the cooperation between the limiting block 36 and the limiting groove 24 can limit the relative rotation between the upper connecting ring 2 and the lower connecting ring 3, avoid loosening between the helical thread 23 and the helical groove 31, further enhance the stability of the connection, and ensure the normal use and sealing effect of the sealing element.

[0034] Working principle: The sealing ring 1 composed of the sealing gasket 11 and the mounting ring 12 is installed on the upper connecting ring 2 and the lower connecting ring 3 respectively. The mounting ring 12 is correspondingly embedded into the upper mounting groove 22 of the upper connecting ring 2 and the lower mounting groove 32 of the lower connecting ring 3. Since the mounting groove is adapted to the mounting ring 12, the mounting ring 12 can be smoothly embedded without the need to excessively force the sealing ring 1 apart, reducing the possibility of deformation caused by installation;

[0035] The helical thread 23 on the bottom outer side of the upper connecting ring 2 is aligned with the helical groove 31 on the inner wall of the lower connecting ring 3, and then the upper connecting ring 2 is rotated to be screwed along the helical groove 31. When the helical thread 23 of the upper connecting ring 2 is screwed into the helical groove 31 of the lower connecting ring 3 to a certain position, the helical rod 35 at one end of the moving groove 34 of the lower connecting ring 3 is rotated to move the limiting block 36 at one end of the helical rod 35 along the moving groove 34 and clamp it into the corresponding limiting groove 24 in the helical thread 23 of the upper connecting ring 2, further enhancing the stability of the connection and ensuring the normal use and sealing effect of the sealing element;

[0036] After the sealing element is put into use, the upper support ring 21 and the upper connecting ring 2, and the lower support ring 33 and the lower connecting ring 3 provide support for the sealing ring 1. At the same time, the first reinforcing rib 25, the second reinforcing rib 26, and the third reinforcing rib 37 enhance the connection strength between the components and evenly distribute stress to each component when the sealing element is under stress, avoiding stress concentration in some weak parts, allowing the sealing element to withstand greater pressure and external force, reducing the possibility of deformation, and prolonging the service life.

[0037] The basic principle and main features of the present application and the advantages of the present application are shown and described above. For those skilled in the art, it is obvious that the present application is not limited to the details of the above exemplary embodiments, and the present application can be implemented in other specific forms without departing from the spirit or basic characteristics of the present application.
