Description

Technical Field

[0001] The utility model relates to the technical field of sealing rings, in particular to a high temperature resistant rubber sealing ring. Background Art

[0002] The rubber sealing ring is an annular cover composed of one or more parts, which is fixed on a ring or washer of the bearing and contacts with another ring or washer or forms a narrow labyrinth gap to prevent the leakage of lubricating oil and the intrusion of foreign objects.

[0003] Most of the existing rubber sealing rings are annular integral structures. However, due to the elasticity of the sealing ring itself, the sealing ring needs to be pulled outwards when installing so that the sealing ring can be put on the installation workpiece. This makes the rubber sealing ring too laborious and inconvenient to install. Utility Model Content

[0004] The utility model aims to solve the above-mentioned shortcomings in the prior art and proposes a high temperature resistant rubber sealing ring.

[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: design a high temperature resistant rubber sealing ring, including a plurality of arc plates, the arc plates are coaxially arranged and the arc plates are equidistantly arranged;

[0006] A first arc-shaped fixing plate is coaxially installed on the top of one end of the arc-shaped plate, and a second arc-shaped fixing plate is coaxially installed on the bottom of the other end of the arc-shaped plate. The formal projections of the first fixing plate and the second fixing plate correspond to each other, so that several arc-shaped plates form a complete ring.

[0007] A connecting plate is arranged between the first fixing plate and the second fixing plate of two adjacent arc-shaped plates, and ends of the connecting plate are respectively connected to one end of the first fixing plate away from the arc-shaped plate and one end of the second fixing plate away from the arc-shaped plate, and the sum of the thicknesses of the first fixing plate, the second fixing plate and the connecting plate corresponds to the arc-shaped plate.

[0008] Preferably, bending grooves are provided at the connection between the first fixing plate and the connecting plate, and at the connection between the second fixing plate and the connecting plate.

[0009] Preferably, the arc-shaped plate, the first fixing plate, the second fixing plate and the connecting plate are all elastic rubber plates.

[0010] Preferably, limit strips are coaxially arranged at both upper and lower ends of the inner side of the arc-shaped plate.

[0011] Preferably, Teflon coating is installed on the surface of the arc plate, the surface of the first fixing plate, and the surface of the second fixing plate.

[0012] The design scheme proposed by the utility model has the following beneficial effects during application:

[0013] 1. The high temperature resistant rubber sealing ring is connected to the fixed plate between two adjacent arc-shaped plates through a connecting plate, so that the sealing ring can be expanded outward so that the sealing ring can be sleeved on the installation workpiece, thereby reducing the obstruction of the sealing ring itself to its installation process.

[0014] 2. The high temperature resistant rubber sealing ring uses a limiting strip to allow the arc plate to lean on the outer wall of the workpiece after being installed on the workpiece, thereby increasing the contact surface and improving the stability of the sealing ring during installation.

[0021] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0022] Reference Figure 1-Figure 5 , a high temperature resistant rubber sealing ring, comprising a plurality of arc plates 1, the arc plates 1 are coaxially arranged and the arc plates 1 are equidistantly arranged;

[0023] A first arc-shaped fixing plate 2 is coaxially installed on the top of one end of the arc-shaped plate 1, and a second arc-shaped fixing plate 3 is coaxially installed on the bottom of the other end of the arc-shaped plate 1. The formal projections of the first fixing plate 2 and the second fixing plate 3 correspond to each other, so that the first fixing plate 2 and the second fixing plate 3 can be overlapped and stacked together, so that several arc-shaped plates 1 form a complete ring.

[0024] A connecting plate 4 is provided between the first fixing plate 2 and the second fixing plate 3 of two adjacent arc-shaped plates 1, and ends of the connecting plate 4 are respectively connected to one end of the first fixing plate 2 away from the arc-shaped plate 1 and one end of the second fixing plate 3 away from the arc-shaped plate 1, so that a plurality of arc-shaped plates 1 are connected, and when the arc-shaped plates 1 are pulled, the plurality of arc-shaped plates 1 can be expanded outward, and the sum of the thicknesses of the first fixing plate 2, the second fixing plate 3 and the connecting plate 4 corresponds to the arc-shaped plate 1, wherein the arc-shaped plate 1, the first fixing plate 2, the second fixing plate 3 and the connecting plate 4 are all elastic rubber plates, so that they form a complete rubber sealing ring.

[0025] Specifically, when using, Figure 5 As shown, the arc plate 1 is unfolded outward and put on the installation workpiece. At this time, the first fixing plate 2 and the second fixing plate 3 will be staggered. Then the inner side of the arc plate 1 is close to the outer wall of the workpiece. At this time, the first fixing plate 2 will be stacked on the second fixing plate 3 again, and the end of the fixing plate will be against the end of the arc plate 1 to limit the position of the fixing plate, so that the arc plate 1 will not be out of position due to the connection method such as the thread between the two workpieces that requires twisting. Finally, another workpiece is placed on the arc plate 1 and fixed. As the two workpieces are connected, the arc plate 1 is squeezed to achieve a sealing effect.

[0026] Furthermore, in order to facilitate the movement of the arc plate 1, bending grooves 5 are provided at the connection between the first fixed plate 2 and the connecting plate 4, and at the connection between the second fixed plate 3 and the connecting plate 4, to facilitate the bending of the fixed plate on the connecting plate 4 so as to facilitate the corresponding stacking between the fixed plates.

[0027] It should be noted that limit strips 6 are coaxially arranged at the upper and lower ends of the inner side of the arc plate 1. After the arc plate 1 is placed on the workpiece, the inner wall of the arc plate 1 will be close to the outer wall of the workpiece, so that the stability of the arc plate 1 when placed can be improved by increasing the contact surface, and in actual use, the limit strip 6 is an elastic rubber block. After the two workpieces are connected, the limit strip 6 will be placed in the edge gap of the connection between the two workpieces and produce elastic deformation, which can improve the tightness of the connection between the workpieces.

[0028] It should be noted that if Figure 4 As shown, Teflon coating 7 is installed on the surface of the arc plate 1, the surface of the first fixed plate 2, and the surface of the second fixed plate 3, which provides the rubber sealing ring with higher high temperature resistance and also improves the corrosion resistance of the sealing ring.

[0029] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
