Description

Technical Field

[0001] This application relates to the field of rubber bellows technology, specifically a rubber bellows sealing structure. Background Technology

[0002] Rubber bellows sealing structure is a sealing device widely used in various industrial and civil fields. It cleverly combines the elasticity of rubber materials with the special structure of bellows, which can effectively prevent fluid (gas or liquid) leakage and ensure the normal operation of the system.

[0003] Currently, when connecting large-diameter corrugated rubber pipes for urban use, sealing rings need to be fitted onto the outer walls of the two corrugated pipe sections respectively. Then, the sleeve at the end of one of the corrugated pipes is fitted onto the outer wall of the connecting corrugated pipe. Before connection, lubricant needs to be applied to the inner walls of the two corrugated pipe sections to facilitate the fitting and connection. However, this connection method is relatively unstable and may loosen when encountering ground fluctuations, which may lead to a reduction in the sealing effect. Utility Model Content

In addition, lubricant needs to be applied to the inner walls of the two corrugated pipes before connection to facilitate the fitting and connection. However, this connection method is relatively unstable and may loosen when encountering ground fluctuations, which will lead to a reduction in the sealing effect.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] This application provides a rubber bellows sealing structure, including a first bellows and a second bellows disposed on one side thereof. The first and second bellows are made of hard rubber. The inner walls of the first and second bellows, which are disposed opposite to each other, abut against a T-shaped sealing ring. The two sides of the T-shaped sealing ring are adapted to the inner walls of the first and second bellows. The outer wall of the T-shaped sealing ring abuts against two arc-shaped plates. The inner walls on both sides of the two arc-shaped plates are provided with positioning mechanisms for positioning the arc-shaped plates. The outer walls of the arc-shaped plates are provided with locking mechanisms for locking the arc-shaped plates.

[0007] By adopting the above technical solution, and by setting a T-shaped sealing ring that fits into the inner walls of the first and second corrugated pipes, fluid leakage can be effectively blocked. At the same time, by using two arc-shaped plates and their positioning mechanism, the arc-shaped plates can be accurately positioned to ensure their stable position with the corrugated pipes. Then, with the help of a locking mechanism, the arc-shaped plates are firmly locked, making the entire sealing structure tightly connected. Compared with traditional connection methods, this structure has strong stability and is not easy to loosen even when encountering ground fluctuations, and can always maintain a good sealing effect, ensuring the stable operation of large-diameter rubber corrugated pipe systems in cities.

[0008] Optionally, the locking mechanism includes two sets of fixing strips welded to the outer walls on both sides of the arc-shaped plate.

[0009] By adopting the above technical solution, the arc-shaped plate can be used to fix the corresponding fixing strip.

[0010] Optionally, a set of bolts is rotatably inserted through the inner wall of each of the two sets of fixing strips, and a nut is threaded onto the outer wall of each set of bolts.

[0011] By adopting the above technical solution, the two sets of arc plates and corresponding fixing strips can be locked and fixed by the cooperation of bolts and nuts.

[0012] Optionally, the positioning mechanism includes two sets of positioning arc rings fixedly installed on the inner wall of the arc plate, and the two sets of positioning arc rings respectively abut against the outer wall of the corresponding first corrugated pipe and second corrugated pipe.

[0013] By adopting the above technical solution, the arc plate can fix the positioning arc ring, and the positioning arc ring can be matched with the corrugations on the outer walls of the first and second corrugated pipes to fix and prevent the arc plate from loosening.

[0014] Optionally, the outer walls of the first and second bellows located inside the two sets of positioning arc rings are respectively fitted with convex sealing rings, and the outer wall of the convex sealing ring abuts against the inner wall of the corresponding arc plate.

[0015] By adopting the above technical solution, the convex sealing ring can further seal the first and second bellows against the arc plate.

[0016] Compared with the prior art, the beneficial effects of the technical solution of this application are as follows:

[0017] The technical solution of this application effectively prevents fluid leakage by setting a T-shaped sealing ring that fits into the inner walls of the first and second corrugated pipes. At the same time, by using two arc-shaped plates and their positioning mechanism, the arc-shaped plates can be accurately positioned to ensure their stable position with the corrugated pipes. Then, with the help of a locking mechanism, the arc-shaped plates are firmly locked, making the entire sealing structure tightly connected. Compared with traditional connection methods, this structure has strong stability and is not easy to loosen even when encountering ground fluctuations, and can always maintain a good sealing effect, ensuring the stable operation of large-diameter rubber corrugated pipe systems in cities.

[0024] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0025] Please see Figure 1-4This application provides a technical solution: a rubber bellows sealing structure, including a first bellows 1 and a second bellows 2 disposed on one side thereon. The first bellows 1 and the second bellows 2 are made of hard rubber. The inner walls of the first bellows 1 and the second bellows 2 are respectively disposed on opposite sides and abut against a T-shaped sealing ring 3. The two sides of the T-shaped sealing ring 3 are adapted to the inner walls of the first bellows 1 and the second bellows 2. The outer wall of the T-shaped sealing ring 3 abuts against two arc-shaped plates 4. The inner walls on both sides of the two arc-shaped plates 4 are provided with positioning mechanisms for positioning the arc-shaped plates 4. The outer walls of the arc-shaped plates 4 are provided with locking mechanisms for locking the arc-shaped plates 4.

[0026] In the technical solution of this application, by setting a T-shaped sealing ring 3 to fit the inner wall of the first corrugated pipe 1 and the second corrugated pipe 2, fluid leakage can be effectively blocked. At the same time, by using two arc-shaped plates 4 and their positioning mechanism, the arc-shaped plates 4 can be accurately positioned to ensure that their position with the corrugated pipe is stable. Then, with the help of the locking mechanism, the arc-shaped plates 4 are firmly locked, so that the entire sealing structure is tightly connected. Compared with the traditional connection method, this structure has strong stability and is not easy to loosen even when encountering ground fluctuations, and can always maintain a good sealing effect, ensuring the stable operation of the large-diameter rubber corrugated pipe system for urban use.

[0027] In the technical solution of this application, such as Figures 1-4 As shown, the positioning mechanism includes two sets of positioning arc rings 5 ​​fixedly installed on the inner wall of the arc plate 4. The two sets of positioning arc rings 5 ​​respectively abut against the outer walls of the corresponding first corrugated pipe 1 and second corrugated pipe 2. The arc plate 4 can fix the positioning arc rings 5, and the corrugated fit between the positioning arc rings 5 ​​and the outer walls of the first corrugated pipe 1 and second corrugated pipe 2 can play a positioning and locking role to prevent the arc plate 4 from loosening.

[0028] In the technical solution of this application, such as Figure 2 and Figure 3 As shown, the outer walls of the first bellows 1 and the second bellows 2 located inside the two sets of positioning arc rings 5 ​​are respectively fitted with convex sealing rings 6. The outer wall of the convex sealing ring 6 abuts against the inner wall of the corresponding arc plate 4. The convex sealing ring 6 can further seal the first bellows 1 and the second bellows 2 with the arc plate 4.

[0029] In the technical solution of this application, such as Figure 1 As shown, the locking mechanism includes two sets of fixing strips 7 welded to the outer walls of both sides of the arc plate 4. The arc plate 4 can fix the corresponding fixing strips 7. A set of bolts 8 are rotatably inserted through the inner walls of the two sets of fixing strips 7. Nuts 9 are threaded onto the outer walls of each set of bolts 8. The cooperation of bolts 8 and nuts 9 can lock and fix the two sets of arc plates 4 and the corresponding fixing strips 7.

[0030] In use, the T-shaped sealing ring 3 is placed between the inner walls of the first bellows 1 and the second bellows 2, which are positioned opposite each other. Because its two sides are adapted to the inner walls of the two bellows, it can effectively prevent fluid leakage. The two arc-shaped plates 4 abut against the outer wall of the T-shaped sealing ring 3. The positioning arc-shaped ring 5 on the inner wall of the arc-shaped plate 4 in the positioning mechanism abuts against the corresponding outer wall of the bellows, so as to achieve precise positioning of the arc-shaped plate 4 and prevent it from loosening. At the same time, the bolts 8 and nuts 9 on the fixing strips 7 on both sides of the arc-shaped plate 4 in the locking mechanism lock and fix the two sets of arc-shaped plates 4 and the corresponding fixing strips 7, so that the arc-shaped plates 4 are firmly locked and the entire sealing structure is tightly connected. Even if the ground fluctuates, it is not easy to loosen, thus ensuring the sealing effect.
