Description

Technical Field

[0001] This utility model relates to the field of corrugated pipes, and in particular to a corrugated pipe with insulating properties. Background Technology

[0002] A corrugated pipe is a pipe with a corrugated shape, usually made of metal, plastic or other flexible materials. Its corrugated structure gives the pipe good flexibility and ductility, allowing it to bend and expand within a certain range. Therefore, it is often used for various purposes such as absorbing vibration, compensating for displacement, sealing and isolation.

[0003] When using a corrugated pipe body to connect two water pipes, the mounting blocks at both ends of the corrugated pipe body are usually fixed to one end of the two water pipes with bolts. After the connection is made, there will usually be a certain gap at the connection. The traditional sealing method is to place the sealing block between the two ends of the corrugated pipe body and the connection of the two water pipes before installation, and then fill the gap by pressing and squeezing the sealing block with bolts. This will cause part of the outer surface of the sealing block to be directly exposed to the air, which is prone to corrosion and damage over time, thereby reducing the sealing effect. Replacement requires disassembling the connection, which involves many steps and is inconvenient to replace, and may affect the use of the corrugated pipe body. Utility Model Content

[0004] The technical problem this utility model aims to solve is that when using a corrugated pipe body to connect two water pipes, the mounting blocks at both ends of the corrugated pipe body are usually fixed to one end of the two water pipes with bolts. After the connection is completed, there is usually a certain gap at the connection. The traditional sealing method is to place the sealing block between the two ends of the corrugated pipe body and the connection of the two water pipes before installation, and then fill the gap by pressing and squeezing the sealing block with bolts. This will cause part of the outer surface of the sealing block to be directly exposed to the air, which is prone to corrosion and damage over time, thereby reducing the sealing effect. Replacement requires disassembling the connection, which involves many steps, is inconvenient for replacement, and can easily affect the use of the corrugated pipe body.

[0005] The technical solution adopted by this utility model to solve its technical problem is: a corrugated pipe, including a corrugated pipe body, both ends of which are provided with sealing devices, and the inner wall of the corrugated pipe body is provided with a reinforcing device. The sealing device can seal and block the connection between the corrugated pipe body and the water pipe by pushing several abutment plates to squeeze several sealing blocks. The reinforcing device can be fixed in the inner wall of the corrugated pipe body with the help of several support telescopic rods and a fixing frame to reinforce and support the inner wall of the corrugated pipe body.

[0006] Preferably, the sealing device includes a first circular ring frame, several abutment plates, and several sealing blocks. Several brackets are fixedly connected to one side of the first circular ring frame, and one end of each bracket is fixedly connected to the outer surface of the corrugated pipe body. One side of each sealing block is adhered to one side of the abutment plate with adhesive. A limiting telescopic rod is symmetrically fixedly connected between one side of the abutment plate and the inner wall of the first circular ring frame. A first spring is sleeved on the outer surface of the limiting telescopic rod. The two ends of the first spring are respectively fixed to one side of the first circular ring frame and one side of the abutment plate. A first protrusion is fixedly connected to one side of the abutment plate. A second circular ring frame is rotatably connected to the inner wall of the first circular ring frame. Several second protrusions are fixedly connected to the inner wall of the second circular ring frame. A limiting mechanism is provided between the second circular ring frame and the first circular ring frame.

[0007] The aforementioned components achieve the following effects: By setting up a sealing device, when using the corrugated pipe body to connect two water pipes, several sealing blocks can be adhered to the abutment plate with adhesive. Then, the second ring frame rotates within the inner wall of the first ring frame, causing the second protrusion to abut against and push the first protrusion, the abutment plate, and the sealing blocks to one end, abutting and fixing them to the outer surface of the connection between the corrugated pipe body and the water pipe. Through the abutment and compression of the abutment plate, the sealing blocks can deform, filling and sealing the gaps between the sealing blocks, improving the integrity and sealing effect of the seal. Finally, a limiting mechanism is used for limiting and fixing. After prolonged use, if the sealing blocks corrode and become damaged, it is not necessary to remove the corrugated pipe body from the water pipe. Simply release the limiting mechanism on the abutment plate and tear off the sealing blocks for replacement, reducing operational steps, facilitating replacement and maintenance, and avoiding affecting the use of the corrugated pipe body.

[0008] Preferably, the limiting mechanism includes a locking block, a plurality of locking grooves are provided on one side of the inner wall of the first ring frame, a sliding hole is provided on one side of the outer surface of the second ring frame, a second spring is fixedly connected to one side of the inner wall of the sliding hole, one end of the second spring is fixed to one side of the locking block, and one end of the locking block passes through the sliding hole and is inserted into the inner wall of the locking groove.

[0009] The effect achieved by the above components is as follows: by setting a limiting mechanism, when the second ring frame slides in the inner wall of the first ring frame, the locking block can be pulled to one end in the inner wall of the sliding hole, causing the second spring to retract. Then, the second ring frame can be rotated to one end in the inner wall of the first ring frame to a certain position. After adjustment, the locking block is released, so that under the reset action of the second spring, one end can be locked into the corresponding slot, fixing the second ring frame, thereby fixing and limiting the abutment plate and sealing block.

[0010] Preferably, a stop is fixedly connected to the outer surface of the second protrusion, and the stop is located on the side of the second protrusion furthest from the first ring frame.

[0011] The effect achieved by the above-mentioned components is that, by setting a stop, after the second protrusion pushes the first protrusion to move to the maximum distance, the stop can block one side of the first protrusion, which is convenient for later fixation.

[0012] Preferably, one end of the first protrusion is rotatably connected to a circular roller, and the circular roller is in rolling connection with the outer surface of the second protrusion.

[0013] The effect achieved by the above components is that by setting the roller, the contact wear between the first protrusion and the second protrusion can be reduced, making it easier to push the first protrusion and improving the service life of both.

[0014] Preferably, the reinforcement device includes several support telescopic rods and two fixed frames. The two ends of the support telescopic rods are respectively fixedly connected to one side of the two fixed frames, and the outer surface of the fixed frames is fixedly connected to the inner wall of the corrugated pipe body.

[0015] The effect achieved by the above-mentioned components is as follows: by setting up a reinforcement device, and by installing the support telescopic rod in the inner wall of the corrugated pipe body through a fixing frame, the inner wall can be reinforced and supported, thereby improving the overall strength of the corrugated pipe body and making it less prone to damage.

[0016] Preferably, the supporting telescopic rods are made of flexible metal, and several supporting telescopic rods are distributed at equal intervals on the fixed frame.

[0017] The effect achieved by the above components is as follows: by using flexible metal material for the support telescopic rods and distributing them at equal intervals, the support telescopic rods can deform accordingly with the bending of the corrugated pipe body during use, which facilitates the use of the corrugated pipe body. At the same time, the equal distribution can provide consistent support force to all positions on the inner wall of the corrugated pipe body, thereby improving the service life of the corrugated pipe body.

[0018] Preferably, both ends of the support telescopic rod are symmetrically fixedly connected with reinforcing rods, and one end of the reinforcing rod is fixed to one side of the fixing frame.

[0019] The effect achieved by the above components is that by setting up reinforcing rods, the connection area between the support telescopic rod and the fixed frame can be increased, making the connection more secure and stable.

[0020] The beneficial effects of this utility model are:

[0021] By setting up a sealing device, when using a corrugated pipe body to connect two water pipes, several sealing blocks can be adhered to the abutment plate with adhesive. Then, the second ring frame rotates in the inner wall of the first ring frame, causing the second protrusion to abut against and push the first protrusion, the abutment plate, and the sealing blocks to one end, abutting and fixing them to the outer surface of the connection between the corrugated pipe body and the water pipe. Through the abutment and compression of the abutment plate, the sealing blocks can be deformed, filling and sealing the gaps between the sealing blocks, improving the integrity and sealing effect. Finally, a limiting mechanism is used for limiting and fixing. After the sealing blocks have been used for a long time and become corroded and damaged, it is not necessary to remove the corrugated pipe body from the water pipe. It is only necessary to release the limiting of the abutment plate and tear off the sealing block for replacement, reducing operation steps, facilitating replacement and maintenance, and avoiding affecting the use of the corrugated pipe body.

[0029] The present invention will now be described in further detail with reference to the accompanying drawings. These drawings are simplified schematic diagrams, illustrating only the basic structure of the present invention, and therefore only show the components relevant to the present invention.

[0030] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "connected" and "linked" should be interpreted broadly. For example, they can refer to a fixed connection, a detachable connection, or an integral connection; they can refer to a mechanical connection or an electrical connection; they can refer to a direct connection or an indirect connection through an intermediate medium. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0031] Figure 1-5 The bellows shown has insulating properties and includes a bellows body 1. Both ends of the bellows body 1 are provided with sealing devices 2. The inner wall of the bellows body 1 is provided with a reinforcing device 3. The sealing devices 2 can press several sealing blocks 24 by pushing several abutment plates 23 to seal and block the connection between the bellows body 1 and the water pipe. The reinforcing device 3 can be fixed in the inner wall of the bellows body 1 by several support telescopic rods 31 and fixed frame 32 to reinforce and support the inner wall of the bellows body 1.

[0032] Figure 3-5The sealing device 2 shown includes a first ring frame 21, several abutment plates 23, and several sealing blocks 24. Several brackets 22 are fixedly connected to one side of the first ring frame 21. One end of the bracket 22 is fixedly connected to the outer surface of the bellows body 1. One side of the sealing block 24 is adhered to one side of the abutment plate 23 by means of adhesive. A limiting telescopic rod 25 is symmetrically fixedly connected between one side of the abutment plate 23 and the inner wall of the first ring frame 21. A first spring 26 is sleeved on the outer surface of the limiting telescopic rod 25. The two ends of the first spring 26 are respectively fixed to one side of the first ring frame 21 and the abutment plate 23. A first protrusion 27 is fixedly connected to one side of the abutment plate 23. A second ring frame 28 is rotatably connected to the inner wall of the first ring frame 21. Several second protrusions 210 are fixedly connected to the inner wall of the second ring frame 28. A limiting mechanism 29 is provided between the second ring frame 28 and the first ring frame 21. When using the corrugated pipe body 1 to connect two water pipes, the mounting blocks at both ends of the corrugated pipe body 1 are usually fixed to one end of the two water pipes with bolts. At this time, several sealing blocks 24 can be adhered to the abutment plate 23 with adhesive. Then, the second ring frame 28 is rotated to a certain position within the inner wall of the first ring frame 21, causing the second protrusion 210 to abut against and push the first protrusion 27. This pushes the abutment plate 23 to one end, causing the limiting telescopic rod 25 and the first spring 26 to be stretched open, so that the sealing blocks 24 abut against and are fixed on the outer surface of the connection between the corrugated pipe body 1 and the water pipe. The pressing and squeezing of the abutting plate 23 can deform the sealing block 24, filling and sealing the gaps between several sealing blocks 24, improving the integrity and sealing effect of the seal. At this time, the adjusted second ring frame 28 is fixed and limited on the first ring frame 21 by the limiting mechanism 29. If the sealing block 24 is corroded and damaged after long-term use, it can be replaced simply by releasing the limiting of the abutting plate 23 and tearing off the sealing block 24. It is not necessary to remove the corrugated pipe body 1 from the water pipe for replacement, reducing operation steps, facilitating replacement and maintenance, and avoiding affecting the use of the corrugated pipe body 1.

[0033] Figure 3-5The limiting mechanism 29 shown includes a locking block 294. A plurality of locking slots 291 are provided on one side of the inner wall of the first ring frame 21. A sliding hole 292 is provided on one side of the outer surface of the second ring frame 28. A second spring 293 is fixedly connected to one side of the inner wall of the sliding hole 292. One end of the second spring 293 is fixed to one side of the locking block 294. One end of the locking block 294 passes through the sliding hole 292 and is inserted into the inner wall of the locking slot 291. By setting a limiting mechanism 29, when the second ring frame 28 slides in the inner wall of the first ring frame 21, the locking block 294 can be pulled to one end in the inner wall of the sliding hole 292, causing the second spring 293 to retract. Then, the second ring frame 28 can be rotated to one end in the inner wall of the first ring frame 21 to a certain position. After adjustment, the locking block 294 is released, allowing one end of it to be locked into the corresponding slot 291 under the reset action of the second spring 293, thus fixing the second ring frame 28 and fixing and limiting the abutment plate 23 and the sealing block 24. A stop block 211 is fixedly connected to the outer surface of the second protrusion 210. The stop block 211 is set on the side of the second protrusion 210 furthest from the first ring frame 21. By setting the stop block 211, after the second protrusion 210 pushes the first protrusion 27 to the maximum distance, the stop block 211 can block one side of the first protrusion 27, which is convenient for later fixing. One end of the first protrusion 27 is rotatably connected to a roller 212, which is in rolling contact with the outer surface of the second protrusion 210. By setting the roller 212, the abutment wear between the first protrusion 27 and the second protrusion 210 can be reduced, making it easier to push the first protrusion 27 and improving the service life of both.

[0034] Figure 2 The reinforcement device 3 shown includes several supporting telescopic rods 31 and two fixing frames 32. The two ends of the supporting telescopic rods 31 are respectively fixedly connected to one side of the two fixing frames 32. The outer surface of the fixing frames 32 is fixedly connected to the inner wall of the corrugated pipe body 1. By installing the supporting telescopic rods 31 into the inner wall of the corrugated pipe body 1 through the fixing frames 32, the inner wall can be reinforced and supported, improving the overall strength of the corrugated pipe body 1 and making it less prone to damage.

[0035] Figure 2The supporting telescopic rods 31 shown are made of flexible metal, and several supporting telescopic rods 31 are evenly distributed on the fixing frame 32. By using flexible metal and evenly distributing the supporting telescopic rods 31, they can deform accordingly with the bending and deformation of the corrugated pipe body 1 during use, making them less likely to affect the use of the corrugated pipe body 1 during support and reinforcement. At the same time, the even distribution ensures consistent support force at all locations on the inner wall of the corrugated pipe body 1, improving its service life. Reinforcing rods 33 are symmetrically fixed to both ends of each supporting telescopic rod 31, with one end of each reinforcing rod 33 fixed to one side of the fixing frame 32. By setting the reinforcing rods 33, the connection area between the supporting telescopic rods 31 and the fixing frame 32 is increased, making the connection more secure and stable.

[0036] Working principle: When using the corrugated pipe body 1 to connect two water pipes, the mounting blocks at both ends of the corrugated pipe body 1 are usually fixed to one end of the two water pipes with bolts. First, the locking block 294 can be pulled to one end in the inner wall of the sliding hole 292, causing the second spring 293 to retract. Then, several sealing blocks 24 are glued to the abutment plate 23. Then, the second ring frame 28 is rotated to a certain position in the inner wall of the first ring frame 21, causing the second protrusion 210 to abut against and push the first protrusion 27, thereby pushing the abutment plate 23 to one end. This causes the limiting telescopic rod 25 and the first spring 26 to be stretched open, so that the sealing blocks 24 abut against and fix to the outer surface of the connection between the corrugated pipe body 1 and the water pipe. By pressing against the abutment plate 23, the sealing block 24 can be deformed, filling and sealing the gaps between several sealing blocks 24, improving the integrity and sealing effect of the seal. At this time, the locking block 294 is released, allowing one end to be inserted into the corresponding slot 291 under the reset action of the second spring 293, fixing the second ring frame 28, thereby fixing and limiting the abutment plate 23 and the sealing block 24. If the sealing block 24 is corroded and damaged after long-term use, it can be replaced without removing the corrugated pipe body 1 from the water pipe. It is only necessary to release the limiting of the abutment plate 23 and tear off the sealing block 24 to replace it, reducing the operation steps, facilitating replacement and maintenance, and avoiding affecting the use of the corrugated pipe body 1.

[0037] By installing the support telescopic rod 31 in the inner wall of the corrugated pipe body 1 through the fixing frame 32, the inner wall can be reinforced and supported, thereby improving the overall strength of the corrugated pipe body 1 and making it less prone to damage.

[0038] Based on the above-described preferred embodiments of this utility model, and through the foregoing description, those skilled in the art can make various changes and modifications without departing from the technical concept of this utility model.
