Description

Technical Field

[0001] This utility model relates to the field of pipeline sealing, and in particular to a pipeline cylindrical double-seal double-plug sealing and leak-proof device. Background Technology

[0002] Existing quick-release pipe end sealing sleeves not only meet sealing requirements but also allow for rapid disassembly when needed, giving the pipeline high adjustability. This type of device is typically used in applications requiring frequent maintenance or replacement of piping systems, such as industrial pipelines, building construction, and refrigerant recovery. However, each end of each pipe requires an independent quick-release pipe end sealing sleeve. Therefore, when it is necessary to quickly remove the sealing sleeves at both ends of the pipe, the two sealing sleeves must be removed sequentially, which still cannot meet the requirement of removing the two sealing sleeves in one step. Utility Model Content

[0003] To overcome the inability to quickly remove the sealing sleeves at both ends of the pipe in one step, this utility model provides a pipe cylindrical double-seal double-plug sealing and leak-proof device.

[0004] The technical implementation scheme of this utility model is as follows: a pipe-type double-sealed and double-plugged sealing and leak-proof device, comprising a pipe body, a first plugging cylinder, a second plugging cylinder, a connecting rod, an elliptical block, a rotating ring, and a locking block; the first plugging cylinder is sleeved at one end of the pipe body; the second plugging cylinder is sleeved at the other end of the pipe body; a connecting rod is fixedly connected to the first plugging cylinder; the connecting rod passes through the second plugging cylinder; an elliptical block is fixedly connected to the connecting rod; a rotating ring is rotatably connected to the second plugging cylinder; a locking block is provided on the rotating ring; and an elliptical insertion hole structure corresponding to the elliptical block is provided on the locking block.

[0005] More preferably, the first sealing cylinder is provided with a first sealing ring; the second sealing cylinder is also provided with a first sealing ring; and the two ends of the pipe body are respectively provided with a first sealing groove structure corresponding to the two first sealing rings.

[0006] More preferably, a sealing plug is fixed to the connecting rod; the second sealing cylinder has a plug hole structure corresponding to the sealing plug.

[0007] More preferably, the sealing plug is provided with a second sealing ring; the second sealing cylinder is provided with a second sealing groove structure corresponding to the second sealing ring.

[0008] More preferably, the first sealing ring, the second sealing ring, and the sealing plug are all made of elastic, corrosion-resistant rubber plug material.

[0009] More preferably, the locking block is slidably connected to the rotating ring via a sliding rod structure; a tension spring is fixedly connected between the locking block and the rotating ring; a fixed concave block is fixedly connected to the second sealing cylinder; and a movable concave block corresponding to the fixed concave block is fixedly connected to the locking block.

[0010] More preferably, the outer ring surface of the card block is provided with several anti-slip protrusions.

[0011] This utility model has the following advantages: A double-sealed, double-plugged sealing and leak-proof device for pipes has a first plugging cylinder and a second plugging cylinder at each end of the pipe body. The connecting rod on the first plugging cylinder is fixed by a locking block connected to a rotating ring on the second plugging cylinder via an elliptical block, achieving double-sealing and double-plugging sealing and leak-proof protection for both ends of the pipe. When quick removal is required, simply manually turn the locking block connected to the rotating ring on the second plugging cylinder to quickly remove both the first and second plugging cylinders in one step. Furthermore, the locking block and the rotating ring are connected movably. During manual turning of the locking block, under the control of the fixed and movable concave blocks, the locking block can be pushed to pull the connecting rod, improving the sealing and leak-proof protection effect of the first and second plugging cylinders. This solves the technical problem of not being able to quickly remove the sealing sleeves at both ends of the pipe in one step. Attached Figure Description

[0020] Example

[0021] This utility model discloses a pipe-type double-seal double-plug sealing and leak-proof device, such as... Figures 1-5 As shown, it includes a pipe body 1, a first sealing cylinder 21, a second sealing cylinder 22, a connecting rod 23, an elliptical block 24, a rotating ring 31, and a locking block 32; one end of the pipe body 1 is fitted with the first sealing cylinder 21; the other end of the pipe body 1 is fitted with the second sealing cylinder 22; the connecting rod 23 is fixedly connected to the first sealing cylinder 21; the connecting rod 23 passes through the second sealing cylinder 22; the end of the connecting rod 23 that passes through the second sealing cylinder 22 is fixedly connected with the elliptical block 24; the rotating ring 31 is rotatably connected to the second sealing cylinder 22; the rotating ring 31 is provided with a locking block 32; the locking block 32 has an elliptical insertion hole 3201 structure corresponding to the elliptical block 24.

[0022] like Figures 3-5 As shown, a first sealing ring 201 is provided inside the first sealing cylinder 21; a first sealing ring 201 is also provided inside the second sealing cylinder 22; a first sealing groove 101 structure corresponding to the two first sealing rings 201 is opened at both ends of the pipe body 1, and the two first sealing rings 201 are initially tightly attached to the corresponding first sealing grooves 101; a sealing plug 25 is fixedly connected to the connecting rod 23; a plug hole 2201 structure corresponding to the sealing plug 25 is opened on the second sealing cylinder 22, and the sealing plug 25 is initially tightly attached to the plug hole 2201; a second sealing ring 2501 is provided on the sealing plug 25; a second sealing groove 2202 structure corresponding to the second sealing ring 2501 is opened on the second sealing cylinder 22, and the second sealing ring 2501 is initially tightly attached to the second sealing groove 2202; the first sealing ring 201, the second sealing ring 2501 and the sealing plug 25 are all made of elastic anti-corrosion rubber plug material.

[0023] like Figures 3-5As shown, the locking block 32 is slidably connected to the rotating ring 31 via a sliding rod structure; a tension spring 33 is fixedly connected between the locking block 32 and the rotating ring 31; a fixed concave block 34 is fixedly connected to the second sealing cylinder 22; a movable concave block 35 corresponding to the fixed concave block 34 is fixedly connected to the locking block 32; the movable concave block 35 is initially in a mutually embedded state with the fixed concave block 34, that is, the concave surface of the movable concave block 35 is in close contact with the convex surface of the fixed concave block 34, and the convex surface of the movable concave block 35 is in close contact with the concave surface of the fixed concave block 34; the outer ring surface of the locking block 32 is provided with several anti-slip protrusions, which can increase friction when the locking block 32 is rotated by hand.

[0024] The fixing steps of the pipe cylindrical double-seal double-plug sealing and leak-proof device of this utility model are as follows: First, as Figure 1 and Figure 2 As shown, the workers place the first sealing cylinder 21 and the second sealing cylinder 22 onto both ends of the pipe body 1, respectively, and insert the first sealing ring 201 on the first sealing cylinder 21 and the first sealing ring 201 on the second sealing cylinder 22 into the corresponding first sealing grooves 101 at both ends of the pipe body 1, so that the first sealing cylinder 21 and the second sealing cylinder 22 provide sealing and leak-proof protection for both ends of the pipe body 1. At the same time, the connecting rod 23 on the first sealing cylinder 21 is passed through the second sealing cylinder 22, so that the elliptical block 24 on the connecting rod 23 passes to the right through the elliptical insertion hole 3201 of the locking block 32, so that the sealing plug on the connecting rod 23... 25 is inserted into the plug hole 2201 of the second sealing cylinder 22, and the second sealing ring 2501 of the sealing plug 25 is inserted into the second sealing groove 2202 of the second sealing cylinder 22, so that the sealing plug 25 provides a sealing and leak-proof protection for the insertion part of the connecting rod 23 and the second sealing cylinder 22. Then, the operator manually turns the locking block 32 to drive the rotating ring 31 to rotate 90 degrees in the forward direction, so that the elliptical insertion hole 3201 of the locking block 32 and the elliptical block 24 are in an interlaced state, so that the connecting rod 23 on the first sealing cylinder 21 is fixed by the locking block 32 connected to the rotating ring 31 on the second sealing cylinder 22 through the elliptical block 24.

[0025] During the manual rotation of the locking block 32, which causes the rotating ring 31 to rotate 90 degrees clockwise, the locking block 32 will cause the movable concave block 35 to rotate 90 degrees. At this time, the convex structure of the movable concave block 35 will move along the inclined surface between the concave and convex structures of the fixed concave block 34. Figure 6As shown, the convex structure of the movable concave block 35 is switched to a convex structure that is tightly attached to the fixed concave block 34. The concave structure of the movable concave block 35 and the convex structure of the fixed concave block 34 are moved away from each other, allowing the movable concave block 35 to push the fixed concave block 34 to push the locking block 32 to the right. The locking block 32 drives the tension spring 33 to stretch. At the same time, the locking block 32 pulls the connecting rod 23 to push the first sealing cylinder 21 further towards the pipe body 1. At the same time, the connecting rod 23 drives the sealing plug 25 to press further towards the second sealing cylinder 22. Meanwhile, the movable concave block 35 is subjected to the reverse extrusion force from the fixed concave block 34. The movable concave block 35 pushes the second sealing cylinder 22 to press further towards the pipe body 1. This further improves the sealing and leak-proof protection effect provided by the first sealing cylinder 21 and the second sealing cylinder 22 to both ends of the pipe body 1, and also further improves the sealing and leak-proof protection effect provided by the sealing plug 25 to the second sealing cylinder 22, completing the operation in the locked state.

[0026] The one-step dismantling steps of the pipe cylindrical double-seal double-plug sealing and leak-proof device of this utility model are as follows: Figure 6 In the locked state, the operator only needs to manually turn the locking block 32 to drive the rotating ring 31 to rotate 90 degrees in the opposite direction, so that the elliptical insertion hole 3201 of the locking block 32 and the elliptical block 24 are aligned again. At the same time, the concave structure of the movable concave block 35 rotates back to the state of being tightly attached to the convex structure of the fixed concave block 34, and the convex structure of the movable concave block 35 rotates back to the state of being tightly attached to the concave structure of the fixed concave block 34, completing one step of unlocking. Then the operator can directly remove the first sealing cylinder 21 and the second sealing cylinder 22 from both ends of the pipe body 1.

[0027] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the principle of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
