Description

Technical Field

[0001] This utility model relates to the field of sealing technology, specifically a rubber ring with a positioning structure. Background Technology

[0002] In many fields such as industrial production, machinery manufacturing, and daily life, rubber rings are widely used as important sealing and connecting components in equipment such as pipe interfaces, valves, pump bodies, and automotive parts. Their main function is to fill the gap between two connecting components through their own elastic deformation, thereby achieving functions such as sealing and preventing leakage, buffering and shock absorption, and reducing friction. As equipment places increasingly higher demands on the performance of sealing components, rubber rings not only need to have good sealing performance, but also need to have reliable positioning capabilities to adapt to higher working pressures, more complex operating environments, and more precise assembly requirements. Therefore, a rubber ring with a positioning structure is needed.

[0003] Existing rubber rings often fail to bond tightly to the stabilizing frame due to inadequate bonding processes or poor material compatibility. This can lead to the stabilizing frame becoming loose or even sliding on the rubber ring. Furthermore, the positioning holes or slots on the stabilizing frame may not match the sealing strip, preventing it from being securely fixed after installation. Under vibrations generated during equipment operation, the sealing strip can easily detach or shift from the stabilizing frame, losing its positioning function for the rubber ring. This lack of positioning directly results in a decrease in sealing performance. Because the rubber ring cannot be precisely positioned in the preset location, its fit with the connecting components is significantly reduced. During equipment operation, as the rubber ring shifts, gaps appear on the originally tight sealing surface, allowing fluid to leak through these gaps. Therefore, a rubber ring with a positioning structure is urgently needed. Utility Model Content

[0004] Therefore, the purpose of this utility model is to provide a rubber ring with a positioning structure to solve the problem that existing rubber rings, when in use, do not have a tight enough fit between the rubber sleeve and the stabilizing frame. This can be caused by poor bonding processes or poor material compatibility, leading to the stabilizing frame becoming loose or even sliding on the rubber sleeve. Furthermore, the positioning holes or slots on the stabilizing frame may not match the size of the sealing strip, making it difficult to securely fix the sealing strip after installation. Under the vibration generated during equipment operation, the sealing strip can easily detach from or shift from the stabilizing frame, losing its positioning function for the rubber ring. This lack of positioning directly leads to a decrease in sealing performance. Because the rubber ring cannot be accurately positioned in the preset position, its fit with the connecting components is greatly reduced. During equipment operation, as the rubber ring shifts, gaps appear on the originally tight sealing surface, allowing fluid to escape through these gaps.

[0005] The problem of leakage from the gaps.

[0006] To achieve the above objectives, this utility model provides the following technical solution: a rubber ring with a positioning structure, comprising a rubber sleeve, an anti-slip groove formed on the inner wall of the rubber sleeve, buckles installed on both the left and right sides of the upper end of the rubber sleeve, an inflation hole formed at the lower end of the rubber sleeve, an expansion air bag installed at one end of the inflation hole, an elastic connecting rope installed inside the rubber sleeve, a stabilizing frame installed at one end of the elastic connecting rope, a sealing strip installed inside the stabilizing frame, a sealing rubber block installed at the upper end of the stabilizing frame, and slots formed on both the left and right ends of the sealing rubber block.

[0007] Preferably, the rubber sleeve has a semi-circular design, and the anti-slip grooves are distributed at equal intervals around the rubber sleeve.

[0008] Preferably, the inflatable air bag is bonded to the rubber sleeve, and the inflatable air bag is arranged symmetrically about the central axis of the rubber sleeve.

[0009] Preferably, the stabilizing frame is movably connected to the rubber sleeve via an elastic connecting rope, and the stabilizing frame is engaged with the sealing strip.

[0010] Preferably, the sealing rubber block is engaged with the rubber sleeve by a snap fastener, and the sealing rubber block is threadedly connected to the stabilizing frame.

[0011] Compared with the prior art, the beneficial effects of this utility model are:

[0012] 1. This utility model, through the setting of a rubber sleeve, a stabilizing frame and a sealing strip, can place the sealing strip through the stabilizing frame in the device, and can have a positioning function for the entire rubber ring when in use. The rubber sleeve maintains a stable shape under the support of the stabilizing frame, and the sealing strip locks the position of the rubber ring through multi-point fixation. Even if it is subjected to strong vibration, temperature change or fluid impact, the rubber ring will not shift or flip.

[0013] 2. This utility model features a rubber sleeve, anti-slip groove, buckle, inflation hole, expansion air bag, elastic connecting rope, stabilizing frame, and sealing rubber block. The sealing rubber block at the top of the stabilizing frame can be moved via the elastic connecting rope. The expansion air bag inside the rubber sleeve is inflated through the inflation hole, causing it to expand. When in use, the multiple inflated air bags fit snugly against the anti-slip groove on the inner wall of the rubber sleeve. Simultaneously, the stabilizing frame can be lifted upwards, and after lifting, the sealing rubber block at the top of the stabilizing frame can also be lifted, ensuring the rubber sleeve remains sealed.

[0019] The technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings. The embodiments described below with reference to the accompanying drawings are exemplary and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0020] The embodiments of this utility model will be described below based on its overall structure.

[0021] Please see Figures 1-4 A rubber ring with a positioning structure includes a rubber sleeve 1. The inner wall of the rubber sleeve 1 has anti-slip grooves 2. Buckles 3 are installed on both the left and right sides of the upper end of the rubber sleeve 1. The rubber sleeve 1 has a semi-circular design, and the anti-slip grooves 2 are evenly distributed around the rubber sleeve 1. The semi-circular rubber sleeve 1 can better seal the required sealing area from all directions during use. An inflation hole 4 is provided at the lower end of the rubber sleeve 1. An expansion air bag 5 is installed at one end of the inflation hole 4. The expansion air bag 5 is adhered to the rubber sleeve 1, and the expansion air bag 5 is positioned in the middle of the rubber sleeve 1. The axis is symmetrically set. The expansion air bag 5 in the device is inflated through the inflation hole 4. The expansion air bag 5 can fill the inside of the rubber sleeve 1. After filling, the sealing rubber block 9 in the device can come into contact with the rubber sleeve 1 to seal the gap. An elastic connecting rope 6 is installed inside the rubber sleeve 1. A stabilizing frame 7 is installed at one end of the elastic connecting rope 6. A sealing strip 8 is installed inside the stabilizing frame 7. A sealing rubber block 9 is installed at the upper end of the stabilizing frame 7. The sealing rubber block 9 has a slot 10 on both the left and right ends.

[0022] Working principle: In use, the position of the stabilizing frame 7 can be tilted to both ends by the elastic connecting rope 6 installed inside the rubber sleeve 1. After tilting, the rubber sleeve 1 can be connected through the hole at the top of the rubber sleeve 1 installed in the device. After the sleeve is installed, the expansion air bag 5 inside the rubber sleeve 1 can be inflated through the air inlet 4. After inflation, the expansion air bag 5 expands, which allows the stabilizing frame 7 to move upward. While the stabilizing frame 7 is moving, the sealing rubber block 9 in the device can be sealed with the round hole at the top of the rubber sleeve 1. After sealing, the sealing rubber block 9 can be connected by the buckle 3. After connection, the sealing position can be kept sealed, thus improving the sealing performance of the device. At the same time, the sealing strip 8 can be used to keep the connection of the entire rubber sleeve 1 stable and prevent it from falling off. This completes the use of the device.
