Description

Technical Field

[0001] This utility model relates to the field of split joint technology, and more specifically, to a split joint with adjustable length. Background Technology

[0002] A pipe sealer is a type of pipe leak stopper. Both pipe sealers and socket-type pipe sealers are emergency pipe repair devices. Socket-type pipe sealers are used to repair leaks at the socket joint of two pipes, while pipe sealers are used to repair leaks at the joint other than the socket. This device has a simple structure consisting of only two main bodies and two rubber gaskets. It is easy to install; simply align the two main bodies at the leak and tighten the nuts to complete the pipe repair. Using this device can save water outage time and reduce repair costs.

[0003] A search revealed that Chinese utility model patent application number CN202222178775.0 discloses a length-adjustable splitter, comprising: a first arc-shaped plate for emergency repair of the broken end of the pipe of an object; a second arc-shaped plate located at one end of the first arc-shaped plate and rotatably connected to the first arc-shaped plate; and limiting components respectively embedded on both sides of the first arc-shaped plate and the second arc-shaped plate.

[0004] When in use, under the action of the first elastic element and the second elastic element, the pull rod is ejected a certain distance due to the influence of elastic potential energy, causing the limiting post outside the pull rod to move to the position of the second set of first internal threads and second internal threads inside the first groove and the second groove, and then manually threaded to move to the next set of first internal threads and second internal threads in sequence, thereby limiting and adjusting the distance between the third arc plate and the fourth arc plate and the first arc plate and the second arc plate.

[0005] Although the length of the split joint can be adjusted by the distance between the third and fourth arc plates and the first and second arc plates, the third and fourth arc plates are connected to the first and second arc plates by tie rods. If the length of the break in the pipeline is long, it is not convenient to seal the break at the tie rod, and it is not convenient to seal the long break, thus reducing its practicality.

[0009] To achieve the above objectives, this utility model provides the following technical solution: an adjustable length splitter, comprising two first arc-shaped plates and two second arc-shaped plates. The two first arc-shaped plates are connected by multiple first bolts, and the two second arc-shaped plates are connected by multiple second bolts. Each of the two first arc-shaped plates has an arc-shaped groove inside, and a third arc-shaped plate is slidably and sealed inside each of the two arc-shaped grooves. The side ends of the two third arc-shaped plates are respectively fixedly connected to the side ends of the two second arc-shaped plates. A first sealing gasket is fixedly connected to the inner wall of each of the two first arc-shaped plates, a second sealing gasket is fixedly connected to the inner wall of each of the two second arc-shaped plates, and a third sealing gasket is fixedly connected to the inner wall of each of the two third arc-shaped plates. The side end of the third sealing gasket is fixedly connected to the corresponding side end of the second sealing gasket, facilitating length adjustment. The third arc-shaped plates and third sealing gaskets facilitate sealing of damaged sections in the pipe between the first and second arc-shaped plates, thus enabling the sealing of longer broken sections in the pipe and improving its practicality.

[0010] The present invention is further configured such that the outer side of the third arc-shaped plate is provided with a notch, and a sealing sleeve is fixedly connected inside the notch. The side end of the sealing sleeve is fixedly connected to the side end of the third sealing gasket to ensure the sealing of the connection between the third arc-shaped plate and the first arc-shaped plate.

[0011] The present invention is further configured such that the third sealing gasket has a beveled edge at one end near the first sealing gasket, and a sealing strip is fixedly connected to the end of the first sealing gasket near the third sealing gasket, so as to ensure the sealing of the connection between the third sealing gasket and the first sealing gasket.

[0012] The present invention is further configured such that the cross-section of the sealing strip is a triangular structure, which facilitates the fit between the side of the sealing strip and the hypotenuse of the third sealing gasket.

[0013] The present invention is further provided with a fourth sealing gasket between the two first arc-shaped plates to ensure the sealing of the connection between the two first arc-shaped plates.

[0014] The present invention is further provided with a fifth sealing gasket between the two second arc-shaped plates to ensure the sealing of the connection between the two second arc-shaped plates.

[0015] The present invention is further configured such that two second arc-shaped plates are symmetrically fixedly connected to two fixing plates, and two first arc-shaped plates are symmetrically fixedly connected to two fixing frames. The two fixing plates are slidably engaged with the two fixing frames respectively. Fixing screws are threadedly connected to both fixing frames. Multiple fixing grooves that are adapted to the fixing screws are evenly provided on both fixing plates, so as to facilitate the fixing of the length of the second arc-shaped plates and the first arc-shaped plates.

[0016] The present invention is further configured such that limiting plates are fixedly connected to both of the fixed plates, which limit the position of the fixed plates and the second arc-shaped plate.

[0017] (III) Beneficial Effects

[0018] Compared with the prior art, this utility model provides a length-adjustable split joint, which has the following characteristics:

[0019] Beneficial effects:

[0020] 1. By sliding the third arc-shaped plate inside the arc-shaped groove, the distance between the first and second arc-shaped plates can be adjusted, facilitating the adjustment of the length of the split. The lengths of the first, second, and third arc-shaped plates are adjusted to be greater than the length of the damaged section on the pipe. Then, the first, second, and third arc-shaped plates are placed over the damaged area on the pipe. Since the first, second, and third arc-shaped plates are respectively fixedly connected to the first, second, and third sealing gaskets, it is easy to seal the damaged area on the pipe. This makes it convenient to seal long broken sections on the pipe, improving its practicality.

[0021] 2. A bevel is provided at the end of the third sealing gasket near the first sealing gasket, and a sealing strip is fixedly connected to the end of the first sealing gasket near the third sealing gasket. When the first bolt is tightened, the first sealing gasket, the third sealing gasket, and the sealing strip compress the pipe, and the pipe compresses the sealing strip, so that the side of the sealing strip is tightly attached to the side of the third sealing gasket, ensuring the sealing of the connection between the first sealing gasket and the second sealing gasket.

[0022] 3. When adjusting the length of the split section, the fixing plate slides inside the fixing frame. After adjusting the split section to the appropriate length, tighten the fixing screws so that the fixing screws are inserted into the corresponding fixing slots and the side ends of the fixing screws abut against the side ends of the fixing slots. This makes it easy to fix the fixing frame and the fixing plate together and to fix the length of the split section. Attached Figure Description

[0032] Please see Figures 1-5An adjustable-length splitter includes two first arc-shaped plates 1 and two second arc-shaped plates 2. The two first arc-shaped plates 1 are connected by multiple first bolts 3, and the two second arc-shaped plates 2 are connected by multiple second bolts 4. A fourth sealing gasket 14 is provided between the two first arc-shaped plates 1 to ensure the sealing of the connection between them. A fifth sealing gasket 15 is provided between the two second arc-shaped plates 2 to ensure the sealing of the connection between them. Each of the two first arc-shaped plates 1 has an arc-shaped groove 5 inside. A third arc-shaped plate 6 is slidably and sealingly arranged inside each of the two arc-shaped grooves 5. A notch 10 is provided on the outside of the third arc-shaped plate 6. A sealing sleeve 11 is fixedly connected inside the 10. The side end of the sealing sleeve 11 is fixedly connected to the side end of the third sealing gasket 9. The side end of the sealing sleeve 11 is in sealing contact with the side end of the arc groove 5 to ensure the sealing of the connection between the third arc plate 6 and the first arc plate 1. The side ends of the two third arc plates 6 are fixedly connected to the side ends of the two second arc plates 2 respectively. A first sealing gasket 7 is fixedly connected to the inner wall of each of the two first arc plates 1. A second sealing gasket 8 is fixedly connected to the inner wall of each of the two second arc plates 2. A third sealing gasket 9 is fixedly connected to the inner wall of each of the two third arc plates 6. The side end of the third sealing gasket 9 is fixedly connected to the side end of the corresponding second sealing gasket 8.

[0033] Specifically, by sliding the third arc-shaped plate 6 inside the arc-shaped groove 5, the distance between the first arc-shaped plate 1 and the second arc-shaped plate 2 can be adjusted, facilitating the adjustment of the length of the split joint. The lengths of the first arc-shaped plate 1, the second arc-shaped plate 2, and the third arc-shaped plate 6 are adjusted to be greater than the length of the broken section on the pipe. Then, the first arc-shaped plate 1, the second arc-shaped plate 2, and the third arc-shaped plate 6 are placed over the broken section on the pipe. Since the first arc-shaped plate 1, the second arc-shaped plate 2, and the third arc-shaped plate 6 are respectively fixedly connected to the first sealing gasket 7, the second sealing gasket 8, and the third sealing gasket 9, it is convenient to seal the broken section on the pipe. This makes it easy to seal long broken sections on the pipe, improving its practicality.

[0034] Please see Figure 3 and Figure 4 The third sealing gasket 9 has a beveled edge 12 at one end near the first sealing gasket 7, and a sealing strip 13 is fixedly connected to one end of the first sealing gasket 7 near the third sealing gasket 9 to ensure the sealing between the third sealing gasket 9 and the first sealing gasket 7. The sealing strip 13 has a triangular cross-section to facilitate the fit between the side of the sealing strip 13 and the beveled edge 12 of the third sealing gasket 9.

[0035] Specifically, a beveled edge 12 is provided at one end of the third sealing gasket 9 near the first sealing gasket 7, and a sealing strip 13 is fixedly connected to one end of the first sealing gasket 7 near the third sealing gasket 9. When the first bolt 3 is tightened, the first sealing gasket 7, the third sealing gasket 9 and the sealing strip 13 compress the pipe, and the pipe compresses the sealing strip 13, so that the side of the sealing strip 13 is tightly attached to the side of the third sealing gasket 9, ensuring the sealing of the connection between the first sealing gasket 7 and the second sealing gasket 8.

[0036] Please see Figure 1 Two second arc-shaped plates 2 are symmetrically fixedly connected to two fixing plates 16, and two first arc-shaped plates 1 are symmetrically fixedly connected to two fixing frames 17. The two fixing plates 16 are slidably engaged with the two fixing frames 17 respectively. Fixing screws 18 are threadedly connected to both fixing frames 17. Multiple fixing grooves 19 that are adapted to the fixing screws 18 are evenly provided on both fixing plates 16. Limiting plates 20 are fixedly connected to both fixing plates 16 to limit the fixing plates 16 and the second arc-shaped plates 2.

[0037] Specifically, when adjusting the length of the split section, the fixing plate 16 slides inside the fixing frame 17. After adjusting the split section to a suitable length, the fixing screw 18 is tightened so that it is inserted into the corresponding fixing groove 19 and the side end of the fixing screw 18 abuts against the side end of the fixing groove 19. This facilitates the fixing frame 17 and the fixing plate 16 to be fixedly connected together, and makes it easy to fix the length of the split section.

[0038] In summary, when using the overall equipment:

[0039] By sliding the third arc-shaped plate 6 inside the arc-shaped groove 5, the distance between the first arc-shaped plate 1 and the second arc-shaped plate 2 is adjusted. The length of the split joint is adjusted according to the length of the damaged section on the pipe, ensuring the length of the split joint is greater than the length of the damaged section. Then, the corresponding first arc-shaped plate 1, second arc-shaped plate 2, and third arc-shaped plate 6 are fastened onto the pipe, covering the damaged section and ensuring the gap between the two third arc-shaped plates 6 avoids the damaged section. Finally, multiple first arc-shaped plates 1, 2, and 6 are tightened. A bolt 3 and multiple second bolts 4 connect the two first arc plates 1 and the two second arc plates 2 together and clamp the pipe. The fourth sealing gasket 14 is in a tight abutment with the first sealing gasket 7. At this time, the fifth sealing gasket 15 is in a tight abutment with the second sealing gasket 8. At the same time, the cooperation of the first sealing gasket 7, the second sealing gasket 8, the third sealing gasket 9, the sealing strip 13 and the sealing sleeve 11 ensures the sealing of the connection between the first arc plate 1, the second arc plate 2 and the third arc plate 6, which can ensure the sealing of the damaged part of the pipe.
