Description

Technical Field

[0001] This utility model relates to the field of pipeline technology, and more specifically, to a leak-proof pipeline. Background Technology

[0002] Pipes, as one of the common items in municipal and housing construction, can transport and discharge water.

[0003] Publication number CN212672624U discloses a leak-proof pipe, the technical solution of which includes a first connecting pipe, a sleeve, and a second connecting pipe; the sleeve is fixedly connected to the end of the second connecting pipe and passes through the first connecting pipe; an elastic sealing ring abuts between the end faces of the first connecting pipe and the second connecting pipe; a locking assembly is installed on the outer walls of the first connecting pipe and the second connecting pipe to fix and lock the two in the combined state; the locking assembly includes at least one clamp and multiple fastening screws; the fastening screws lock and fix the clamp after splicing through the threaded hole provided on the outside of the clamp.

[0004] In the above technical solution, when connecting pipes, the first and second connecting pipes are spliced ​​together and placed into the clamp. Then, the clamp is locked with fastening screws. At this time, the first and second connecting pipes are restricted by the clamp and cannot be separated, thus completing the pipe installation. At the same time, by setting an elastic sealing ring at the splice of the first and second connecting pipes, the sealing effect between the first and second connecting pipes can be improved, preventing water leakage at the splice of the first and second connecting pipes.

[0005] However, with the above technical solution, the elastic sealing ring between the first and second connectors will inevitably age after the pipeline has been used for a long time. Therefore, the pipeline needs to be maintained regularly. If the elastic sealing ring needs to be replaced during pipeline maintenance, the first and second connectors need to be separated. At this time, the pipeline cannot drain water normally.

[0006] Therefore, a new solution is needed to address this problem. Utility Model Content

[0007] In view of the shortcomings of the existing technology, the purpose of this utility model is to provide a leak-proof pipe, which solves the problem that when the elastic sealing ring inside the pipe needs to be replaced, the pipe needs to be separated, which leads to the pipe being unable to drain normally.

[0008] The above-mentioned technical objective of this utility model is achieved through the following technical solution: a leak-proof pipe, including a pipe body and a clamp, the clamp including a first connecting frame and a second connecting frame, a fixing ring fixedly connected to the first connecting frame, a connecting pipe fixedly connected to the inner wall of the fixing ring, the connecting pipe and the inner wall of the pipe body being slidably connected, a sealing strip being provided between the fixing ring and the pipe body, the two ends of the sealing strip being detachably connected, and when the two ends of the sealing strip are installed together, the sealing strip is arranged in a ring shape, the second connecting frame and the first connecting frame being detachably connected and abutting against the outer wall of the pipe body.

[0009] By adopting the above structural configuration, when connecting the pipe, the pipe body is placed inside the first connecting frame, and the connecting pipe is inserted into the pipe body, making contact with the inner wall of the pipe body. Then, the sealing strip is fitted onto the connecting pipe, and the two ends of the sealing strip are connected together. Next, the pipe body is pushed, causing it to abut against the side wall of the sealing strip. Then, the second connecting frame and the first connecting frame are installed together, thus completing the pipe installation. When the sealing strip needs to be replaced, the first and second connecting frames are separated, and then the pipe body is pulled, disengaging the pipe body from the sealing strip. The process involves contacting the pipe body and connecting pipe together, then removing the two ends of the sealing strip from the connecting pipe, and finally fitting a new sealing strip onto the connecting pipe and reconnecting the two ends. After installation, the pipe body is driven back to its original position and contacts the sealing strip, thus replacing it. The connecting pipe design ensures that the pipe body remains connected during sealing strip replacement, allowing for continued normal drainage even when the elastic sealing ring inside the pipe is replaced.

[0010] The present invention is further configured such that: an installation piece and an installation frame are fixedly connected to both ends of the sealing strip respectively; the installation piece and the inner wall of the installation frame are slidably connected; an elastic piece is fixedly connected to the side wall of the installation piece; the elastic piece and the inner wall of the installation frame are slidably connected; and a through groove is provided on the side wall of the installation frame for the elastic piece to engage. When the elastic piece is in its natural state, the elastic piece and the through groove engage with each other.

[0011] By employing the aforementioned mounting plate and mounting frame configuration, when the two ends of the sealing strip are installed together, pressure is applied to the elastic plate, causing it to deform. The mounting plate is then inserted into the mounting frame, moving the elastic plate within it. When the elastic plate reaches the through groove, it loses its restraint and begins to deform and recover, engaging with the through groove. This fixes the mounting plate and mounting frame together, achieving the effect of connecting the two ends of the sealing strip. When it is necessary to remove the two ends of the sealing strip, pressure is applied to the elastic plate located in the through groove, causing it to disengage from the through groove and enter the mounting frame. Then, a pulling force is applied to the sealing strip, pulling the mounting plate and elastic plate out of the mounting frame, thus removing the two ends of the sealing strip.

[0012] The present invention is further configured such that the longitudinal section of both the mounting plate and the mounting frame is arc-shaped.

[0013] By adopting the above-mentioned mounting plate and mounting frame, the mounting frame and mounting plate can better fit against the outer wall of the connecting pipe, thereby improving the sealing effect of the sealing strip between the pipe body and the connecting ring.

[0014] The present invention is further configured such that: a limiting ring is fixedly connected to the inner wall of the pipe body, and the limiting ring has an inclined surface on the side away from the pipe body.

[0015] By adopting the aforementioned limiting ring, the sealing effect between the pipe body and the connecting pipe can be improved. At the same time, the inclined surface of the limiting ring can reduce the accumulation of impurities in the water between the limiting ring and the pipe body.

[0016] The present invention is further configured such that: an installation plate is rotatably connected to the outer wall of the pipe body; a fixing plate is fixedly connected to both sides of the first and second connecting frames; a plurality of through holes are opened on the side walls of the installation plate and the fixing plate; bolts are provided at the through holes; and nuts are threaded onto the bolts.

[0017] By using the aforementioned mounting plate and fixing plate, after installing connecting frame one and connecting frame two together, the mounting plate is rotated so that the through holes on the mounting plate and the through holes on the fixing plate correspond to each other. Then, bolts are inserted into the through holes and nuts are screwed onto the bolts, thereby achieving the effect of fixing the pipe body and connecting frame one and connecting frame two together. The mounting plate and fixing plate further fix the pipe body and connecting frame one and connecting frame two, preventing the pipe body from separating from connecting frame one and connecting frame two.

[0018] The present invention is further configured such that: two limiting rings are fixedly connected to the outer wall of the pipe body, and the mounting plate is located between the two limiting rings.

[0019] By adopting the above-mentioned limiting ring, the installation plate can be prevented from separating from the pipe body, thus avoiding affecting the effect between the pipe body and connecting frame one and connecting frame two.

[0020] The present invention is further configured such that when the bolt is inserted into the through hole, the inner walls of the first and second connecting frames abut against the outer wall of the pipe body.

[0021] By adopting the above structural design, the sealing effect between the pipe body and connecting frame one and connecting frame two can be further improved after the pipe is installed, thus enhancing the sealing performance.

[0022] In summary, this utility model has the following beneficial effects: When it is necessary to replace the sealing strip, pull the pipe body and release the contact between the pipe body and the sealing strip, while driving the pipe body and the connecting pipe to always be in contact with each other. Then, disconnect the two ends of the sealing strip and replace the sealing strip. After the replacement is completed, drive the pipe body back to its original position and make contact with the sealing strip, thereby completing the effect of replacing the sealing strip. Through the setting of the connecting pipe, the pipe body can still be connected when replacing the sealing strip, so that the pipe can still maintain normal drainage when replacing the elastic sealing ring inside the pipe.

For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0030] A type of leak-proof pipe, such as Figures 1-3 As shown, the system includes a pipe body 1 and a clamp. The clamp includes a first connecting frame 2 and a second connecting frame 3. A fixing ring 4 is fixedly connected to the first connecting frame 2, and a connecting pipe 5 is fixedly connected to the inner wall of the fixing ring 4. The connecting pipe 5 is slidably connected to the inner wall of the pipe body 1. A sealing strip 6 is provided between the fixing ring 4 and the pipe body 1. The two ends of the sealing strip 6 are detachably connected. When the two ends of the sealing strip 6 are installed together, the sealing strip 6 is arranged in a ring. The second connecting frame 3 and the first connecting frame 2 are detachably connected and abut against the outer wall of the pipe body 1. When connecting the pipe 5, the pipe body 1 is placed into the first connecting frame 2, and the connecting pipe 5 is inserted into the pipe body 1 and contacts the inner wall of the pipe body 1. Then, the sealing strip 6 is sleeved on the connecting pipe 5, and the two ends of the sealing strip 6 are installed together. Then, the pipe body 1 is pushed, causing the pipe body 1 to abut against the side wall of the sealing strip 6. Then, the second connecting frame 3 and the first connecting frame 2 are detachably connected and abut against the outer wall of the pipe body 1. Connecting frames 1 and 2 are installed together to complete the pipe installation. When the sealing strip 6 needs to be replaced, connecting frames 1 and 2 are separated. Then, the pipe body 1 is pulled to remove the contact between the pipe body 1 and the sealing strip 6, while keeping the pipe body 1 and the connecting pipe 5 in constant contact. Then, the two ends of the sealing strip 6 are removed from each other and pulled out of the connecting pipe 5. The new sealing strip 6 is then fitted onto the connecting pipe 5, and the two ends of the sealing strip 6 are installed together. After the sealing strip 6 is installed, the pipe body 1 is driven back to its original position and contacts the sealing strip 6, thus completing the replacement of the sealing strip 6. Through the setting of the connecting pipe 5, the pipe body 1 can still be connected when replacing the sealing strip 6, so that the pipe can still maintain normal drainage when replacing the elastic sealing ring inside the pipe.

[0031] like Figure 2 , Figure 3 As shown, mounting pieces 7 and mounting frames 8 are fixedly connected to both ends of the sealing strip 6, respectively. The mounting pieces 7 and the inner walls of the mounting frames 8 are slidably connected. An elastic piece 9 is fixedly connected to the side wall of the mounting piece 7, and the elastic piece 9 is slidably connected to the inner wall of the mounting frames 8. A through groove 10 is provided on the side wall of the mounting frames 8 for the elastic piece 9 to engage. When the elastic piece 9 is in its natural state, the elastic piece 9 and the through groove 10 engage with each other. When the two ends of the sealing strip 6 are installed together, pressure is applied to the elastic piece 9, causing it to deform. Then, the mounting piece 7 is inserted into the mounting frame 8, and the elastic piece 9 moves within the mounting frame 8. When the elastic piece 9 moves to the through groove 10, it loses its restraint and begins to deform and recover, restoring itself and... The through grooves 10 interlock to fix the mounting piece 7 and the mounting frame 8 together, thus achieving the effect of connecting the two ends of the sealing strip 6. When it is necessary to remove the two ends of the sealing strip 6 from each other, pressure is applied to the elastic piece 9 located at the through groove 10, causing the elastic piece 9 and the through groove 10 to disengage and enter the mounting frame 8. Then, a pulling force is applied to the sealing strip 6 to pull the mounting piece 7 and the elastic piece 9 out of the mounting frame 8, thus achieving the effect of removing the two ends of the sealing strip 6 from each other. The longitudinal section of both the mounting piece 7 and the mounting frame 8 is arc-shaped, which allows the mounting frame 8 and the mounting piece 7 to better fit against the outer wall of the connecting pipe 5, improving the sealing effect of the sealing strip 6 between the pipe body 1 and the connecting ring.

[0032] like Figure 2 As shown, a limiting ring 11 is fixedly connected to the inner wall of the pipe body 1. The limiting ring 11 has an inclined surface on the side away from the pipe body 1, which can improve the sealing effect between the pipe body 1 and the connecting pipe 5. At the same time, by using the inclined surface of the limiting ring 11, the occurrence of impurities in the water between the limiting ring 11 and the pipe body 1 can be reduced.

[0033] like Figure 1 , Figure 2As shown, a mounting plate 12 is rotatably connected to the outer wall of the pipe body 1. Fixing plates 13 are fixedly connected to both sides of connecting frame 1 (2) and connecting frame 2 (3). Several through holes 14 are opened on the side walls of the mounting plate 12 and fixing plates 13. Bolts 15 are installed at the through holes 14, and nuts 16 are threaded onto the bolts 15. After connecting frame 1 (2) and connecting frame 2 (3) are installed together, the mounting plate 12 is rotated so that the through holes 14 on the mounting plate 12 correspond to the through holes 14 on the fixing plates 13. Then, the bolts 15 are inserted into the through holes 14, and the nuts 16 are screwed onto the bolts 15. This completes the mutual fixation of the pipe body 1 and connecting frames 1 (2) and 2 (3). The design further secures the pipe body 1 and connecting frames 1 and 2, preventing separation between the pipe body 1 and connecting frames 1 and 2. Two limiting rings 17 are fixedly connected to the outer wall of the pipe body 1, and the mounting plate 12 is located between the two limiting rings 17, preventing separation between the mounting plate 12 and the pipe body 1 and avoiding affecting the connection between the pipe body 1 and connecting frames 1 and 2. When the bolt 15 is inserted into the through hole 14, the inner walls of connecting frames 1 and 2 and the outer wall of the pipe body 1 abut against each other, further improving the sealing effect between the pipe body 1 and connecting frames 1 and 2 after pipe installation, thus enhancing the sealing performance.

[0034] The working principle of this utility model is as follows: When connecting pipe 5, the pipe body 1 is placed into the connecting frame 2, and the connecting pipe 5 is inserted into the pipe body 1 and comes into contact with the inner wall of the pipe body 1. Then, the sealing strip 6 is put on the connecting pipe 5, and the two ends of the sealing strip 6 are installed together. Then, the pipe body 1 is pushed, causing the pipe body 1 to abut against the side wall of the sealing strip 6. Then, the connecting frame 3 and the connecting frame 2 are installed together, thereby completing the installation of the pipe.

[0035] When it is necessary to replace the sealing strip 6, separate the connecting frame 2 and the connecting frame 3. Then pull the pipe body 1 to remove the contact between the pipe body 1 and the sealing strip 6, while keeping the pipe body 1 and the connecting pipe 5 in constant contact. Then remove the two ends of the sealing strip 6 from each other and pull the sealing strip 6 out of the connecting pipe 5. Then put the new sealing strip 6 on the connecting pipe 5 and install the two ends of the sealing strip 6 together. After installing the sealing strip 6, drive the pipe body 1 back to its original position and make contact with the sealing strip 6. This completes the replacement of the sealing strip 6. Through the setting of the connecting pipe 5, the pipe body 1 can still be connected when replacing the sealing strip 6, so that the pipe can still maintain normal drainage when replacing the elastic sealing ring inside the pipe.

[0036] The above description is merely a preferred embodiment of this utility model. The protection scope of this utility model is not limited to the above embodiments. All technical solutions falling within the scope of this utility model's concept are protected. It should be noted that for those skilled in the art, any improvements and modifications made without departing from the principle of this utility model should also be considered within the protection scope of this utility model.
