Abstract
Description
Technical Field
[0001] This utility model relates to the field of high-pressure pipeline plug technology, and in particular to an expansion-type high-pressure pipeline plug that is easy to disassemble. Background Technology
[0002] A plug, also known as a pipe cap, end cap, or pipe cover, is a key pipe fitting used in pipeline systems to seal the end of a pipe or an unused interface. Its core function is to achieve pipeline sealing, isolate the medium, and protect the inside of the pipe. It is widely used in various pipeline scenarios, including civil and industrial applications.
[0003] In the existing technology, there are various types of plugs, including expansion plugs. In the process of using expansion plugs, the plug is fitted with the pipe end diameter wall. Then, a tool is used to press the ball head into the plug, and the curved surface of the ball head pushes the internal sealing component to expand radially, so that it is tightly pressed against the inner wall of the pipe. However, once the ball expansion plug is inserted into the plug, the ball surface and the inside of the plug generate hard friction. Due to the curved surface and limited space, the ball is difficult to be clamped by tools. As a result, the ball head, plug and pipe end are easily damaged during forced disassembly, making the plug unusable. Utility Model Content
[0004] The purpose of this invention is to overcome the shortcomings of the existing technology and provide an expansion-type high-pressure pipeline plug that is easy to disassemble.
[0005] To achieve the above objectives, this utility model adopts the following technical solution: a conveniently disassembled expansion-type high-pressure pipeline plug, comprising a quick-release mechanism, one end of which is provided with an anti-collision mechanism, the quick-release mechanism comprising a pipeline body, a second conical ring being provided on the inner surface of the pipeline body, the inner surface of the pipeline body being adapted to and connected to the outer side of the second conical ring, an expansion sleeve being provided on the inclined surface of the second conical ring, the inclined surface of the second conical ring contacting the inner side of the expansion sleeve, a first conical ring being provided on the inner side of the expansion sleeve, the inner side of the expansion sleeve being slidably contacting the inclined surface of the first conical ring, a rotating rod being provided on the inner wall of the first conical ring, the inner wall of the first conical ring being threadedly connected to the threaded portion of the rotating rod, one end of the rotating rod being rotatably connected to the inner wall of the second conical ring, the radial wall of the pipeline body contacting the outer side of the collision sleeve, a fitting cover being provided on the outer side of the rotating rod, the outer side of the rotating rod being rotatably connected to the inner wall of the fitting cover through it, and a positioning groove being provided at one end of the fitting cover.
[0006] In a preferred embodiment, the anti-touch mechanism includes a cover, a positioning block is provided on the inner side of the cover, the inner side of the cover is fixedly connected to one end of the positioning block, the outer side of one end of the positioning block is engaged with the inner surface of the positioning groove, and one end of the cover is in contact with one end of the fitting cover.
[0007] In a preferred embodiment, the inner side of the fitting cover is threaded to one end of the pipeline body, and a spring is provided on the inner wall of the fitting cover, with the inner wall of the fitting cover being fixedly connected to the top of the spring.
[0008] In a preferred embodiment, the bottom end of the spring is provided with an inner rod, the bottom end of the spring is fixedly connected to the top side of the inner rod, and the outer side of the inner rod is slidably connected to the inner wall of the fitting cover.
[0009] In a preferred embodiment, one end of the inner rod is provided with an arc-shaped frame, one end of the inner rod is fixedly connected to one end of the arc-shaped frame, a fixing member is provided on the inner wall of the middle end of the arc-shaped frame, the inner wall of the middle end of the arc-shaped frame is threadedly connected to the outer side of the fixing member, and the outer side of one end of the fixing member is threadedly connected to the inner wall of the fitting cover.
[0010] In a preferred embodiment, a triangular block is provided on the outer side of the rotating rod, and the outer side of the rotating rod is fixedly connected to one end of the triangular block. An arc-shaped plate is provided on the inclined surface of the triangular block, and the inclined surface of the triangular block is engaged with the concave part of the arc surface of the arc-shaped plate.
[0011] In a preferred embodiment, one end of the top side of the arc-shaped plate is fixedly connected to the bottom side of the middle end of the arc-shaped frame.
[0012] Compared with the prior art, the advantages and positive effects of this utility model are as follows: 1. By rotating the rotating rod, the first conical ring moves a short distance toward the second conical ring. The radial force generated by the conical surface contact of the first conical ring forces the expansion sleeve to undergo elastic deformation. Under the action of external force, it fits tightly against the pipe wall. By reversing the rotating rod, the first conical ring returns to its original position. During this process, no external force is exerted on the expansion sleeve, allowing it to return to its original shape. Then, the threaded connection between the fitting cap and the pipe body is released. The fitting cap is then pulled to one end, thereby allowing the first conical ring, the expansion sleeve, and the second conical ring to detach from the pipe body without damage. 2. As the rotating rod rotates, the triangular block on the circumference will rotate accordingly. When it is necessary to lock the position of the rotating rod, the inner recess of the arc plate will be engaged and abut against the inclined surface of the triangular block under the action of the spring, thereby restricting the rotating rod to prevent accidental reversal. Finally, the arc frame is fixed to the fitting cover by using a fastener, so that it is not affected by the spring and does not have a slight undulating movement. Attached Figure Description

A conical ring 16 is provided on the inner surface of the pipeline body 11. The inner surface of the pipeline body 11 is adapted to connect with the outer side of the conical ring 16. An expansion sleeve 15 is provided on the inclined surface of the conical ring 16. The inclined surface of the conical ring 16 contacts the inner side of the expansion sleeve 15. The inner side of the expansion sleeve 15 is provided with a conical ring... The inner side of the expansion sleeve 15 slides in contact with the inclined surface of the conical ring 14. A rotating rod 13 is provided on the inner wall of the conical ring 14, and the inner wall of the conical ring 14 is threadedly connected to the threaded portion of the rotating rod 13. One end of the rotating rod 13 is rotatably connected to the inner wall of the second conical ring 16. The radial wall of the pipe body 11 contacts the outer side of the collision sleeve. A fitting cover 12 is provided on the outer side of the rotating rod 13, and the outer side of the rotating rod 13 is rotatably connected to the inner wall of the fitting cover 12. One end of the fitting cover 12 has a positioning groove 113. The inner side of 2 is threaded to one end of the pipe body 11. A spring 112 is provided on the inner wall of the fitting cover 12. The inner wall of the fitting cover 12 is fixedly connected to the top of the spring 112. An inner rod 111 is provided at the bottom end of the spring 112. The bottom end of the spring 112 is fixedly connected to the top side of the inner rod 111. The outer side of the inner rod 111 is slidably connected to the inner wall of the fitting cover 12. An arc-shaped frame 19 is provided at one end of the inner rod 111. One end of the inner rod 111 is fixedly connected to one end of the arc-shaped frame 19. The middle of the arc-shaped frame 19... A fastener 110 is provided on the inner wall of the end. The inner wall of the middle end of the arc frame 19 is threaded to the outer side of the fastener 110. The outer side of one end of the fastener 110 is threaded to the inner wall of the fitting cover 12. A triangular block 17 is provided on the outer side of the rotating rod 13. The outer side of the rotating rod 13 is fixedly connected to one end of the triangular block 17. An arc plate 18 is provided on the inclined surface of the triangular block 17. The inclined surface of the triangular block 17 is engaged with the concave part of the arc surface of the arc plate 18. One end of the top side of the arc plate 18 is fixedly connected to the bottom side of the middle end of the arc frame 19.
[0022] In this embodiment, the plug of the easily disassembled expansion-type high-pressure pipeline body 11 is designed with an expansion sleeve 15 between the second conical ring 16 and the first conical ring 14. The second conical ring 16 and the expansion sleeve 15 have the same diameter. The second conical ring 16 and the expansion sleeve 15 are fitted inside the pipeline body 11. The first conical ring 14 has a slightly smaller diameter than the second conical ring 16. A rotating rod 13 is rotatably connected to the inner wall of the second conical ring 16. The outer side of the rotating rod 13 has a threaded part. The rotating rod 13 with the threaded part is connected to the inner wall of the first conical ring 14. The outer side of the rotating rod 13 is located on the fitting cover 12 through rotation. The end of the fitting cover 12 is threaded to the pipeline body 11. Thus, the fitting cover 12 is connected to the pipeline body 11, so that the second conical ring 16 is positioned inside the pipeline body 11. Then, the fitting cover 12 is... The rotating rod 13 at the center rotates, and when the rotating rod 13 rotates, the cone ring 14 moves a short distance toward the cone ring 16. During the movement, the cone ring 14 uses the radial force generated by the cone surface to force the expansion sleeve 15 to undergo elastic deformation, causing it to expand slightly. Under the action of external force, it fits tightly against the pipe wall, thereby achieving a high-pressure sealing effect. Finally, by reversing the rotating rod 13, the cone ring 14 returns to its original position. During this process, no external force is applied to the expansion sleeve 15, allowing it to return to its original shape. Then, the threaded connection between the fitting cover 12 and the pipe body 11 is released, and the fitting cover 12 is pulled to one end, thereby allowing the cone ring 14, the expansion sleeve 15, and the cone ring 16 to disengage from the pipe body 11, thus quickly releasing the seal and pressure, achieving rapid and non-destructive sealing of the high-pressure pipe body 11. Triangular blocks 17 are installed circumferentially on the rotating rod 13, and there are multiple triangular blocks 17. An arc-shaped frame 19 is installed at one end of the fitting cover 12. An arc-shaped plate 18 is located on the bottom side of the middle end of the arc-shaped frame 19. The inner side of the arc-shaped plate 18 has a recess that matches the inclined surface of the triangular block 17. Inner rods 111 are fixed at both ends of the arc-shaped frame 19. The outer side of the inner rods 111 is located in a groove at one end of the fitting cover 12. A spring 112 is located in the groove at one end of the fitting cover 12, so that the spring 112 is connected to the inner rod 111. Therefore, during the rotation of the rotating rod 13, the triangular block 17 on the circumference will rotate accordingly. When it is necessary to lock the position of the rotating rod 13, the inner recess of the arc plate 18 will be engaged and abut against the inclined surface of the triangular block 17 under the action of the spring 112, thereby restricting the rotating rod 13 to prevent accidental reversal. Finally, by using the fixing member 110 to fix the arc frame 19 to the fitting cover 12, it is not affected by the spring 112 and will have a slight undulating movement, further ensuring that the angle of the rotating rod 13 after rotation is fixed. Example
[0023] like Figure 1-3As shown, the anti-touch mechanism 2 includes a cover 21, a positioning block 22 is provided on the inner side of the cover 21, the inner side of the cover 21 is fixedly connected to one end of the positioning block 22, the outer side of one end of the positioning block 22 is engaged with the inner surface of the positioning groove 113, and one end of the cover 21 is in contact with one end of the fitting cover 12.
[0024] In this embodiment, the positioning groove 113 opened at one end can fit with the positioning block 22 on the inner side of one end of the cover 21. Then, when the cover 12 is connected to the pipeline body 11 and the structural adjustment is completed, the positioning block 22 on the cover 21 fits with the positioning groove 113, which restricts the cover 21 and makes it difficult for it to fall off the cover 12. At the same time, the cover 21 will cover the exposed structure at the end of the cover 12, forming a flat external contour, preventing the exposed structure from being loosened by accidental human touch during use, and playing a protective role against collision and misoperation.
[0025] Working principle: like Figure 1-6 As shown, the fitting cover 12 is connected to the pipe body 11, allowing the second conical ring 16 to be positioned inside the pipe body 11. Then, the rotating rod 13 at the center of the fitting cover 12 is rotated. When the rotating rod 13 rotates, the first conical ring 14 moves a short distance toward the second conical ring 16. During this movement, the first conical ring 14 uses the radial force generated by the conical surface contact to force the expansion sleeve 15 to undergo elastic deformation, causing it to expand slightly and fit tightly against the pipe wall under the action of external force. By reversing the rotating rod 13, the first conical ring 14 returns to its original position. During this process, the expansion sleeve 15 is no longer affected. An external force is applied to restore it to its original shape. Then, the threaded connection between the fitting cover 12 and the pipeline body 11 is released. The fitting cover 12 is then pulled to one end, thereby disengaging the cone ring 14, expansion sleeve 15, and cone ring 16 from the pipeline body 11, releasing the sealing state of the pipeline body 11. Finally, by engaging the positioning block 22 on the cover 21 with the positioning groove 113, the cover 21 is restricted, making it difficult for it to fall off the fitting cover 12. At the same time, the cover 21 will cover the exposed structure at the end of the fitting cover 12, and the cover 21 can completely cover the operating parts at the end of the fitting cover 12.
[0026] The above description is merely a preferred embodiment of the present utility model and is not intended to limit the present utility model in any other way. Any person skilled in the art may make changes or modifications to the above-disclosed technical content to create equivalent embodiments for application in other fields. However, any simple modifications, equivalent changes, and modifications made to the above embodiments based on the technical essence of the present utility model without departing from the technical solution of the present utility model shall still fall within the protection scope of the technical solution of the present utility model.
