Technical Field
[0001] The utility model relates to the technical field of sealing rings, in particular to a combined pressure-resistant sealing ring. Background Art
[0002] A combined sealing ring refers to a sealing ring in which two or more sealing rings are installed and used in combination with each other. It can greatly improve the performance of the sealing ring, and because of its own material, it has high pressure resistance. It is often used in combination of parts in industries such as automobiles.
[0003] When using a traditional combined sealing ring, one sealing ring is generally placed on the arc surface of another sealing ring, and the two components are combined and installed with each other through the clamping of the surface groove, and then installed on other metal components for use. However, it is found in actual use that the connection stability of the two sealing rings is poor when only relying on the surface grooves to connect and install the two sealing rings. When subjected to strong external pressure, they will become loose due to severe deformation, making it difficult to ensure stable use, affecting the use effect of the sealing ring and difficult to stably protect the components. Utility Model Content

A combined pressure-resistant sealing ring is proposed.
[0005] In order to achieve the above-mentioned purpose, the utility model adopts the following technical scheme: a combined pressure-resistant sealing ring, comprising a first sealing ring, a second sealing ring and a stabilizing device, the first sealing ring and the second sealing ring are installed and connected to each other through the stabilizing device, the stabilizing device comprises a plurality of fixing columns, and the plurality of fixing columns are fixedly connected to the inner wall of the second sealing ring, an installation groove is provided on the circular arc surface of the first sealing ring, the first sealing ring is clamped on the inner wall of the installation groove, the inner wall of the installation groove is provided with a plurality of evenly distributed fixing grooves, and the plurality of fixing columns are clamped with the inner walls of the plurality of fixing grooves, the circular arc surface of the first sealing ring is provided with a plurality of evenly distributed reinforcement grooves, and the circular arc surface of the sealing ring is fixedly connected with a plurality of evenly distributed reinforcement blocks, and the plurality of reinforcement blocks are respectively clamped with the plurality of reinforcement grooves.

[0009] Preferably, inner walls of the plurality of fixing grooves are respectively fixedly connected with a plurality of reinforcement protrusions, and the plurality of reinforcement protrusions abut against the arc surface of the fixing column.
[0010] The effect achieved by the above components is that, by setting the reinforcing protrusions, when the fixing column is inserted into the fixing groove, it is squeezed by the reinforcing protrusions, so that it is not easy to separate from each other, thereby better assembling and installing the components.
[0011] Preferably, a plurality of positioning grooves are formed on the inner wall of the installation groove of the first sealing ring, and a plurality of positioning blocks evenly distributed circumferentially are fixedly connected to one side surface of the second sealing ring, and the plurality of positioning blocks are respectively plugged into the plurality of positioning grooves.
[0012] The effect achieved by the above components is that the connection between the two sealing ring components is made closer through the plug-in arrangement of the positioning groove and the positioning block, and thus it is less likely to cause abnormal deviation and shaking during use.
[0013] Preferably, a plurality of evenly distributed stabilizing blocks are fixedly connected to the inner wall of the second sealing ring, and the cross-sections of the plurality of stabilizing blocks are trapezoidal.
[0014] The effect achieved by the above components is that the contact friction between the inner wall of the second sealing ring and the first sealing ring installation groove is further increased by the setting of the stabilizing block, so that the second sealing ring is less likely to rotate and deviate.
[0015] Preferably, a reinforcement device is provided on one side surface of the second sealing ring, and the reinforcement device includes a reinforcement ring. An assembly groove is opened on one side surface of the second sealing ring, and the reinforcement ring is plugged into the inner wall of the assembly groove, and the reinforcement ring abuts against the inner wall of one side of the installation groove.
[0016] The effect achieved by the above components is that when the first sealing ring and the second sealing ring are assembled and installed together, it is not easy to produce gaps, so that they are more stable and tight, so that during use, they can better resist the external pressure strength, and further improve the use effect of the components.
[0017] Preferably, a reinforcement ring is fixedly connected to one side surface of the reinforcement ring, a groove is formed on one side surface of the mounting groove, and the reinforcement ring is clamped on the inner wall of the groove.
[0018] The effect achieved by the above components is: through the provision of the reinforcing ring, the connection strength between the reinforcing ring and the second sealing ring is further improved, thereby better filling the gap between the first sealing ring and the second sealing ring, ensuring the stable combination of the two components.
[0019] Preferably, a reinforcement film is fixedly connected to the same side surface of the reinforcement ring as the reinforcing ring, and the surface of the reinforcement film is coated with glue.
[0020] The effect achieved by the above components is: through the provision of the reinforcement film, the connection between the reinforcement ring and the first sealing ring is made more stable and less likely to separate, thereby making the connection between the first sealing ring and the second sealing ring more fit.

[0030] Reference Figure 1 - Figure 5 As shown, in this embodiment: the stabilizing device 3 includes a plurality of fixing columns 33, and the plurality of fixing columns 33 are fixedly connected to the inner wall of the second sealing ring 2. A mounting groove 31 is provided on the arc surface of the first sealing ring 1, and the first sealing ring 1 is clamped on the inner wall of the mounting groove 31. The inner wall of the mounting groove 31 is provided with a plurality of evenly distributed fixing grooves 32, and the plurality of fixing columns 33 are clamped with the inner walls of the plurality of fixing grooves 32. A plurality of evenly distributed reinforcement grooves 35 are provided on the arc surface of the first sealing ring 1, and a plurality of evenly distributed reinforcement blocks 36 are fixedly connected to the arc surface of the sealing ring, and the plurality of reinforcement blocks 36 are respectively clamped with the plurality of reinforcement grooves 35. When the first sealing ring 1 is clamped, the plurality of fixing grooves 32 are clamped with the inner walls of the plurality of fixing grooves 32. When the ring 1 and the second sealing ring 2 are assembled and used, the second sealing ring 2 is first installed in the installation groove 31 on the surface of the first sealing ring 1, so that the several fixing columns 33 on the inner wall of the second sealing ring 2 are sequentially clamped in the several fixing grooves 32 on the inner wall of the installation groove 31, and at the same time, the several reinforcement blocks 36 on the second sealing ring 2 will be clamped in the several reinforcement grooves 35 on the surface of the first sealing ring 1. At this time, the first sealing ring 1 and the second sealing ring 2 will be more stable and firm when assembled and installed, and will not easily loosen or detach. It can also better resist external pressure, further improve the pressure resistance performance, improve the use effect of the components, and better protect the normal use of the installed components.
[0031] Reference Figure 1 - Figure 5As shown, in the present embodiment: the cross-sections of several reinforcement grooves 35 are T-shaped, the cross-sectional dimensions of several reinforcement grooves 35 are matched with several reinforcement blocks 36, and the shape adaptation arrangement of the reinforcement grooves 35 and the reinforcement blocks 36 makes the connection more stable and firm, thereby further improving the use effect of the stabilizing device 3, and the inner walls of several fixing grooves 32 are respectively fixedly connected with several reinforcement protrusions 34, and several reinforcement protrusions 34 abut against the arc surface of the fixing column 33. Through the arrangement of the reinforcement protrusions 34, when the fixing column 33 is inserted into the fixing groove 32, it is squeezed by the reinforcement protrusions 34, so that it is not easy to separate from each other, thereby better combining and installing the components.

A plurality of evenly distributed stabilizing blocks 39 are fixedly connected to the inner wall of the second sealing ring 2, and the cross-sections of the plurality of stabilizing blocks 39 are trapezoidal. By means of the arrangement of the stabilizing blocks 39, the contact friction between the inner wall of the second sealing ring 2 and the mounting groove 31 of the first sealing ring 1 is further increased, thereby making it more difficult for the second sealing ring 2 to rotate and deviate.

The reinforcing ring 41 is located on the same side surface of the reinforcing ring 43 and is fixedly connected to a reinforcing film 44, and the surface of the reinforcing film 44 is coated with glue. Through the provision of the reinforcing film 44, the connection between the reinforcing ring 41 and the first sealing ring 1 is more stable and not easy to separate, thereby making the first sealing ring 1 and the second sealing ring 2 more connected and fit.
[0035] Working principle: When the first sealing ring 1 and the second sealing ring 2 are installed in combination for use, first install the second sealing ring 2 in the installation groove 31 on the surface of the first sealing ring 1, so that the several fixing columns 33 on the inner wall of the second sealing ring 2 are sequentially clamped in the several fixing grooves 32 on the inner wall of the installation groove 31, and at the same time, the several reinforcement blocks 36 on the second sealing ring 2 will be clamped in the several reinforcement grooves 35 on the surface of the first sealing ring 1, and the positioning blocks 38 on the second sealing ring 2 will be inserted into the positioning grooves 37 on the inner wall of the first sealing ring 1.
