[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meanings as commonly understood by those skilled in the art to which this application belongs. The terms used in the specification of the application are only for the purpose of describing specific embodiments and are not intended to limit this application. The terms "including" and "having" and any variations thereof in the specification and claims of this application and the above-mentioned drawings are intended to cover non-exclusive inclusions. The terms "first", "second", etc. in the specification and claims of this application or the above-mentioned drawings are used to distinguish different objects, not to describe a specific order.

[0020] References herein to "embodiments" mean that a particular feature, structure, or characteristic described in connection with the embodiments may be included in at least one embodiment of the present application. The appearance of this phrase in various places in the specification does not necessarily refer to the same embodiment, nor does it constitute an independent or alternative embodiment that is mutually exclusive of other embodiments. It is understood, both explicitly and implicitly, by those skilled in the art that the embodiments described herein may be combined with other embodiments.

[0021] The present invention provides a V-shaped cloth-inserted sealing ring. Figure 1-5 As shown, it includes a sealing ring skeleton 1, and the inner cavity of the sealing ring skeleton 1 has a V-shaped cloth sealing ring 2. An annular cavity is opened near the top of the inner cavity of the sealing ring skeleton 1, and an annular reinforcement rib 6 is connected to the inner wall of the annular cavity near the top. An annular reinforcement plate 4 is provided at the bottom of the annular reinforcement rib 6, and the side walls of the annular reinforcement plate 4 are respectively connected to the inner wall of the annular cavity near the bottom. A fixing groove is opened near the center of the edge of the inner cavity of the V-shaped cloth sealing ring 2, and the inner cavities of several fixing grooves are provided with a fixing component 3; several fixing components 3 include a guide plate 31 located at the center of the inner cavity of several fixing grooves away from the center of the inner cavity of the V-shaped cloth sealing ring 2, and several guide plates 31 are arranged in a circular array with the center of the inner cavity of the V-shaped cloth sealing ring 2 as the symmetry axis.

[0022] It should be noted that, since the existing V-shaped cloth-strap sealing ring is usually an integrated structure and cannot be disassembled and assembled, and has poor strength, in order to solve the problems that arise during the use of the existing V-shaped cloth-strap sealing ring, this solution solves the problem that the existing V-shaped cloth-strap sealing ring is usually an integrated structure and cannot be disassembled and assembled, and has poor strength by adding a fixing component 3 inside the fixed groove on the V-shaped cloth-strap sealing ring 2 and cooperating with the various components inside the annular cavity of the sealing ring skeleton 1.

[0023] In a further preferred embodiment of the present invention, Figure 1-4 As shown, several guide plates 31 are connected to a clamping rod 32 near the center of the inner cavity of the V-shaped cloth-clamped sealing ring 2, and a clamping hole matching the clamping rod 32 is opened near the center of the edge of the bottom of the inner cavity of the sealing ring frame 1, and several clamping rods 32 are movably connected to the adjacent clamping holes at one end away from the center of the inner cavity of the V-shaped cloth-clamped sealing ring 2.

[0024] In this embodiment, when the staff is about to assemble the sealing ring frame 1 and the V-shaped cloth sealing ring 2 for use, the staff will place the V-shaped cloth sealing ring 2 inside the sealing ring frame 1, and then the staff will rotate the V-shaped cloth sealing ring 2 to drive the four clamping rods 32 to rotate. When the four clamping rods 32 are rotated to the same horizontal position as the adjacent clamping holes, the staff will stop rotating the V-shaped cloth sealing ring 2. At this time, the four reset springs 35 begin to extend outward after the external force disappears, thereby driving the four guide plates 31 to expand outward, so that the four guide plates 31 can move the four clamping rods 32 When the V-shaped cloth sealing ring 2 is to be separated from the sealing ring frame 1, the staff presses the four clamping rods 32 into the adjacent fixing grooves to release the limitation of the V-shaped cloth sealing ring 2, which is convenient for the staff to quickly separate the V-shaped cloth sealing ring 2 from the sealing ring frame 1, thereby achieving the purpose of effectively disassembling and assembling the V-shaped cloth sealing ring and improving the convenience of using the V-shaped cloth sealing ring.

[0025] In a further preferred embodiment of the present invention, Figure 2 and 3 As shown, several guide plates 31 are connected to the center of the inner center of the V-shaped cloth-strap sealing ring 2 with a reset spring 35, and one end of the reset spring 35 near the inner center of the V-shaped cloth-strap sealing ring 2 is respectively connected to the center of the inner wall of the adjacent fixing groove near the inner center of the V-shaped cloth-strap sealing ring 2.

[0026] In this embodiment, due to the elastic restoring function of the four restoring springs 35 , the four restoring springs 35 can quickly push the four clamping rods 32 into the adjacent clamping holes through the four guide plates 31 .

[0027] In a further preferred embodiment of the present invention, Figure 2 and 3 As shown, guide holes are opened at the centers of both sides of the inner cavities of several guide plates 31 away from the centers of the inner cavities of adjacent clamping rods 32, and the inner cavities of two adjacent guide holes are movably connected with guide rods 34. The ends of two adjacent guide rods 34 close to the center of the inner cavity of the V-shaped cloth-clamped sealing ring 2 pass through the inner cavities of the adjacent guide holes, and are connected to the centers of the inner walls of the adjacent fixing grooves close to the center of the inner cavity of the V-shaped cloth-clamped sealing ring 2, and the ends of two adjacent clamping rods 32 away from the center of the inner cavity of the V-shaped cloth-clamped sealing ring 2 pass through the inner cavities of the adjacent guide holes and are connected to baffles 33.

[0028] In this embodiment, the four guide plates 31 can slide on two adjacent guide rods 34 when expanding outward, thereby limiting the positions of the four guide plates 31 so that the four guide plates 31 can move smoothly. At the same time, a baffle 33 is connected to one end of several guide rods 34 away from the center of the inner cavity of the V-shaped cloth sealing ring 2, thereby blocking the four guide plates 31 and preventing the four guide plates 31 from being overloaded.

[0029] In a further preferred embodiment of the present invention, Figure 4 and 5 As shown, there is an annular buffer plate 5 at the bottom of the annular reinforcement rib 6, and the side walls of the annular buffer plate 5 are respectively connected to the inner wall of the annular cavity near the center, the top of the annular buffer plate 5 is connected to the bottom of the annular reinforcement rib 6, and the bottom of the annular buffer plate 5 is connected to the top of the annular reinforcement plate 4.

[0030] In this embodiment, an annular reinforcing plate 4, an annular buffer plate 5 and an annular reinforcing rib 6 are connected inside the annular cavity, so that the strength of the V-shaped cloth-stitched sealing ring can be improved, thereby preventing the V-shaped cloth-stitched sealing ring from being damaged due to insufficient strength, thereby extending the service life of the V-shaped cloth-stitched sealing ring to a certain extent.

[0031] In a further preferred embodiment of the present invention, Figure 1 and 2 As shown, the side wall of the V-shaped cloth-inserted sealing ring 2 is in contact with the inner wall of the sealing ring frame 1 near the bottom, and the size of the V-shaped cloth-inserted sealing ring 2 is smaller than that of the sealing ring frame 1.

[0032] In this embodiment, by setting the V-shaped cloth-inserted sealing ring 2 to a size smaller than the sealing ring frame 1, the V-shaped cloth-inserted sealing ring 2 and the sealing ring frame 1 can be better assembled together for use, thereby ensuring the integrity of the V-shaped cloth-inserted sealing ring structure.
