Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe connection reinforcement technology, and in particular to a pipe connection anti-leakage sealing reinforcement device. Background Technology
[0002] Pipeline connections are weak points in fluid transport systems, prone to leakage due to media corrosion, pressure fluctuations, installation errors, or aging seals. This not only wastes resources but can also pose safety hazards (such as gas leaks or chemical contamination). Pipeline connection leak-proof sealing and reinforcement devices strengthen and reinforce the seals at pipeline connections, providing long-term protection for pipeline interfaces.
[0003] Chinese patent document CN211667337U discloses a municipal water supply and drainage pipeline connection device, including a first connecting pipe and a second connecting pipe. A first flange is fixedly connected to the end of the first connecting pipe, and a second flange is fixedly connected to the end of the second connecting pipe. The first flange and the second flange are installed using fixing bolts. This utility model relates to the field of municipal engineering technology. This municipal water supply and drainage pipeline connection device achieves the goal of replacing the traditional pipe end with a sealing strip and a groove, and adding a limiting device at the flange connection. The limiting device reinforces the flange connection, with the sealing groove corresponding to the sealing strip and the claw corresponding to the groove, improving the stability of the limiting device and thus stabilizing and reinforcing the flange connection. A support device is also provided to support the pipeline connection, further improving the stability of the limiting device and thus enhancing the pipeline connection stability, reducing pipeline leakage, and meeting usage requirements.
[0004] The existing technology has the following problems: Although the above-mentioned utility model can improve the stability of pipeline connection through limiting device and support device, it relies solely on sealing strip to achieve sealing and lacks auxiliary pre-tightening and buffer structure. When the pipeline vibrates or undergoes slight displacement due to thermal expansion and contraction, sealing gaps are likely to occur. After long-term use, the sealing reliability will gradually decrease. In addition, the limiting device is installed and fixed by bolts, resulting in low disassembly and assembly efficiency during pipeline maintenance. Utility Model Content
[0005] This utility model provides a leak-proof sealing and reinforcement device for pipe connections to solve the problems mentioned in the background art.
[0006] To solve the above-mentioned technical problems, the technical solution adopted by this utility model is as follows: A leak-proof sealing and reinforcement device for pipe connections includes two arc-shaped plates, which are semi-circular and distributed vertically. Two clamping plates are provided inside the arc-shaped plates, which are semi-annular. Rubber pads are provided on opposite sides of the two clamping plates. A driving mechanism is provided inside the arc-shaped plates. A mounting base is provided on the outer side of the lower arc-shaped plate, and a fixing mechanism is provided on the upper part of the mounting base. A mounting plate is provided on the outer side of the upper arc-shaped plate.
[0007] Preferably, the driving mechanism includes a lead screw, which is disposed inside the arc-shaped plate. The lead screw has a bidirectional thread, and both ends of the lead screw are provided with rollers.
[0008] Preferably, a compression spring is provided on each of the two clamping plates on opposite sides, and the side of the compression spring away from the clamping plate is installed on the inner wall of the arc-shaped plate.
[0009] Preferably, the arc-shaped plate has two sliding rods inside, the clamping plate is disposed on the outer periphery of the sliding rods, and the compression spring is disposed on the outer periphery of the sliding rods.
[0010] Preferably, the fixing mechanism includes a positioning block, which is installed on the upper part of the mounting base. The positioning block has two locking blocks inside, and the mounting plate has a locking groove inside, in which the locking blocks engage.
[0011] Preferably, a sliding plate is provided on each of the two locking blocks on opposite sides, a compression spring is provided on the side of the sliding plate away from the locking block, and a lever is provided on the upper part of the sliding plate.
[0012] Preferably, the positioning block has a second sliding rod inside, the sliding plate is disposed on the outer periphery of the second sliding rod, and the compression spring is sleeved on the outer periphery of the second sliding rod.
[0013] Compared with the prior art, the present invention has the following beneficial effects: 1. This utility model provides a leak-proof sealing and reinforcement device for pipe connections. By setting a driving mechanism, the double-threaded screw and the rotating wheel can drive two clamping plates to move along the slide rod to clamp the pipe connection. The rubber pad can enhance the sealing performance. At the same time, the compression spring sleeved on the outer periphery of the slide rod can provide continuous pre-tightening force and buffer the vibration or deformation stress of the pipe, ensuring that the clamping is stable and the sealing is reliable, effectively preventing leakage.
[0014] 2. This utility model provides a leak-proof sealing and reinforcement device for pipe connections. By setting a fixing mechanism, the positioning block and the mounting plate can quickly position the upper and lower arc plates. When the sliding plate moves along the sliding rod, it drives the locking block to engage or disengage from the locking groove. The compression spring two sleeved on the outer periphery of the sliding rod can ensure that the locking block is stably engaged. With the help of the lever, it is easy to operate manually, realize the quick disassembly and assembly and stable locking of the upper and lower arc plates, and improve the installation efficiency and ease of use of the device.

[0017] To make the technical means, creative features, objectives and effects of this utility model easier to understand, the present utility model will be further described below in conjunction with specific embodiments.
[0018] like Figure 1 - Figure 5 As shown, a pipe connection anti-leakage sealing and reinforcement device includes two arc-shaped plates 1, which are semi-circular and distributed vertically. The arc-shaped plates 1 serve as the main support frame of the device, used to support internal components and enclose the pipe connection. Two clamping plates 2 are provided inside the arc-shaped plates 1. The clamping plates 2 are semi-circular and can fit against the outer wall of the pipe to clamp and fix the pipe. Rubber pads are provided on opposite sides of the two clamping plates 2. The rubber pads can enhance the sealing between the clamping plates 2 and the pipe, and at the same time buffer the rigid contact during clamping. A driving mechanism 3 is provided inside the arc-shaped plates 1. The driving mechanism 3 is used to drive the clamping plates 2 to move radially along the pipe to adjust the clamping force. A mounting base 4 is provided on the outer side of the lower arc plate 1. The mounting base 4 provides a mounting foundation for the fixing mechanism 6. The fixing mechanism 6 is provided on the upper part of the mounting base 4. The fixing mechanism 6 is used to realize the quick connection and locking of the upper and lower arc plates 1. A mounting plate 5 is provided on the outer side of the upper arc plate 1. The mounting plate 5 cooperates with the fixing mechanism 6 to make the upper and lower arc plates 1 form a closed ring structure.
[0019] like Figure 4 As shown, the drive mechanism 3 includes a lead screw 31, which is located inside the arc plate 1. The lead screw 31 has a bidirectional thread, and when it rotates, it can drive the two clamping plates 2 on both sides to move synchronously in opposite directions, thereby clamping or releasing the pipe. Both ends of the lead screw 31 are provided with a rotating wheel 34, which facilitates manual rotation of the lead screw 31 to adjust the clamping force.
[0020] like Figure 4 As shown, compression springs 33 are provided on opposite sides of the two clamping plates 2. The side of the compression springs 33 away from the clamping plates 2 is installed on the inner wall of the arc plate 1. The compression springs 33 can provide continuous preload force to help the clamping plates 2 fit tightly against the pipe, while buffering the stress caused by pipe vibration or temperature deformation, and avoiding sudden changes in clamping force.
[0021] like Figure 4 As shown, the inside of the arc plate 1 is provided with two slide rods 32, and the clamping plate 2 is provided on the outer periphery of the slide rods 32. The slide rods 32 can guide the clamping plate 2 to move smoothly in the radial direction and prevent the clamping plate 2 from shifting or tilting. The compression spring 33 is sleeved on the outer periphery of the slide rods 32. The slide rods 32 provide guidance for the compression spring 33 and prevent the spring from twisting and failing.
[0022] like Figure 5 As shown, the fixing mechanism 6 includes a positioning block 61, which is installed on the upper part of the mounting base 4. The positioning block 61 is used to position the mounting plate 5 to ensure that the upper and lower arc plates 1 are aligned. The positioning block 61 has two locking blocks 63 inside, and the mounting plate 5 has a slot 67 inside. The locking blocks 63 engage with the slot 67. The mounting plate 5 is fixed to the positioning block 61 through the cooperation of the locking blocks 63 and the slot 67, thereby locking the upper and lower arc plates 1.
[0023] like Figure 5 As shown, a sliding plate 62 is provided on the opposite side of each of the two locking blocks 63. The sliding plate 62 can drive the locking blocks 63 to move horizontally, so as to engage or disengage the locking blocks 63 from the slots 67. A compression spring 66 is provided on the side of the sliding plate 62 away from the locking blocks 63. The compression spring 66 can push the sliding plate 62 to keep the locking blocks 63 locked in the slots 67, ensuring a stable connection. A toggle block 64 is provided on the upper part of the sliding plate 62. The toggle block 64 makes it easy to manually move the sliding plate 62 to separate the locking blocks 63 from the slots 67.
[0024] like Figure 5 As shown, the positioning block 61 is provided with a slide bar 65 inside, and the slide plate 62 is provided on the outer periphery of the slide bar 65. The slide bar 65 can guide the slide plate 62 to move smoothly and prevent the slide plate 62 from jamming or deviating. The compression spring 66 is sleeved on the outer periphery of the slide bar 65. The slide bar 65 provides guidance for the compression spring 66 and avoids the spring from deforming or misaligning.
[0025] The working principle of this utility model is as follows: First, two semi-circular arc-shaped plates 1, arranged vertically, are fastened to the outside of the pipe connection. By moving the lever 64 on the upper part of the sliding plate 62 in the fixing mechanism 6, the sliding plate 62 moves along the sliding rod 65 inside the positioning block 61 and compresses the compression spring 66. The mounting plate 5 on the outer side of the upper arc-shaped plate 1 is aligned with the positioning block 61 on the upper part of the mounting base 4 on the outer side of the lower arc-shaped plate 1. After releasing the lever 64, the compression spring 66 returns to its original position, pushing the sliding plate 62 and causing the locking block 63 to engage with the mounting plate. Within the slot 67 of plate 5, the upper and lower arc-shaped plates 1 are locked and fixed. Then, by rotating the wheels 34 at both ends of the lead screw 31 in the drive mechanism 3, the lead screw 31 with bidirectional thread drives the two clamping plates 2 to move relative to each other along the slide bar 32. At the same time, the compression spring 33 on the opposite side of the clamping plate 2 provides pre-tightening force, so that the two semi-circular clamping plates 2 are tightly clamped on both sides of the pipe connection. The rubber gasket on the opposite side of the clamping plate 2 further enhances the sealing effect. Finally, the above structure works together to achieve the functions of leak-proof sealing and reinforcement at the pipe connection.
[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claims. The scope of protection of this utility model is defined by the appended claims and their equivalents.
