Description

Technical Field

[0001] The present invention relates to the field of pipeline sealing technology, and in particular to a reusable pipeline sealing device. Background Art

[0002] Civil engineering construction often involves pre-buried pipes, which typically require sealing the pipe openings to prevent soil and rocks from entering the pipes. Conventional technology often employs end plates installed at the pipe openings, which are bolted to the pipe openings to achieve this sealing function.

[0003] However, the method of sealing with end plates combined with bolts requires a special wrench tool to tighten the bolts, which is cumbersome to operate. On the other hand, it is necessary to pre-process mounting holes on the pipe for bolt connection, which not only affects the production and processing of the pipe, but the mounting holes may also cause damage to the pipe itself. Summary of the Invention

[0004] The object of the present invention is to provide a reusable pipeline sealing device which is easy to use, can be directly applied to existing pipelines to achieve lossless sealing of pipeline openings.

[0005] To solve the above problems, the present invention provides a reusable pipe sealing device, including an end cover for blocking the pipe opening, a first fastening strap is provided on the upper side of the end cover and a second fastening strap is provided on the lower side, the first fastening strap is provided with a first left tie extending to the left and a first right tie extending to the right on the side away from the end cover, the second fastening strap is provided with a second left tie extending to the left and a second right tie extending to the right on the side away from the end cover, the first left tie and the second left tie are used to be wrapped around the left side of the pipe and are detachably connected to each other, and the first right tie and the second right tie are used to be wrapped around the right side of the pipe and are detachably connected to each other.

[0006] The above solution arranges a first fastening band and a second fastening band on the upper side and the lower side of the end cover respectively, so that after the end cover is plugged into the pipe opening, the first fastening band and the second fastening band are respectively attached to the upper side and the lower side of the pipe, and then the first left tie and the second left tie are wrapped around the left side of the pipe and connected to each other, and the first right tie and the second right tie are wrapped around the right side of the pipe and connected to each other. At this time, the first fastening band and the second fastening band are wrapped around and fixed relative to the pipe, and the end cover is fixed relative to the pipe opening. Compared with the prior art, the above solution fixes the end cover relative to the pipe opening by wrapping the first fastening band and the second fastening band around the pipe. It is not only simple and convenient to operate, but also can be repeatedly disassembled and used. In addition, it does not require additional tools and does not require processing of the pipe structure itself, and has good practicality.

[0007] Preferably, the end surface of the end cover facing the pipe opening is provided with a raised clamping platform, which is annular and is used to be inserted into the pipe opening, thereby achieving a better blocking effect of the end cover on the pipe opening.

[0008] Preferably, the clamping platform is in a circular ring shape so as to be adaptable to most pipe opening shapes.

[0009] Preferably, the upper side wall and the lower side wall of the card table are provided with a raised fastening layer, and the fastening layer is made of elastic material. Since the first fastening belt and the second fastening belt are respectively arranged on the upper side and the lower side of the end cover, the upper and lower parts of the end cover will be subjected to more direct tension. Therefore, by arranging the fastening layer on the upper side wall and the lower side wall of the card table, a greater friction resistance can be generated between the fastening layer and the inner wall of the pipe after the card table is inserted into the pipe opening, thereby achieving a more stable blocking effect of the end cover on the pipe opening.

[0010] Preferably, the first left tie and the first right tie are both provided with a plurality of locking teeth distributed along the left-right direction, and the second left tie and the second right tie are both provided with a snap fit, and the snap fit is used to snap fit to the locking teeth, so that the snap fit of the second left tie and the second right tie can realize the mutual connection of the first fastening strap and the second fastening strap by snap fit with the locking teeth of the first left tie and the second right tie.

[0011] Preferably, the fastener comprises a frame, a short shaft, and an elastic locking tongue, wherein the short shaft is connected to the frame, and the elastic locking tongue is connected to the short shaft. The frame of the second left strap is provided with a first opening for inserting the first left strap and a second opening arranged opposite the corresponding elastic locking tongue. The frame of the second right strap is provided with a first opening for inserting the first right strap and a second opening arranged opposite the corresponding elastic locking tongue. The elastic locking tongue is tilted to achieve abutment against the locking teeth. With this structure, by inserting the first left strap into the first opening of the frame of the second left strap, one end of the elastic locking tongue can abut against the locking teeth, thereby achieving the connection between the first and second left straps. When it is necessary to release the connection between the first and second left straps, it is only necessary to push the elastic locking tongue from the second opening to separate the locking teeth. The same applies to the first and second right straps.

[0012] Preferably, the frame shell is provided with a cover for closing the second opening, thereby preventing the elastic locking tongue from being accidentally touched.

[0013] Preferably, the first and second fastening belts are provided with anti-slip marks on the side facing the pipeline, thereby increasing the friction resistance of the first and second fastening belts relative to the pipeline and ensuring a more stable blocking effect of the end cover on the pipeline opening.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative work are within the scope of protection of the present invention. It should also be noted that all directional indications in the embodiments of the present invention (such as up, down, left, right, front, back, inside, and outside) are only used to explain the relative position relationship, movement status, etc. between the various components under a certain specific posture (as shown in the drawings). If the specific posture changes, the directional indication will also change accordingly.

[0025] See also Figures 1-6 An embodiment of the present invention provides a reusable pipe sealing device, comprising an end cap 1 for plugging the pipe opening, a first fastening strap 2 being provided on the upper side of the end cap 1 and a second fastening strap 3 being provided on the lower side, a first left fastening strap 21 extending to the left and a first right fastening strap 22 extending to the right being provided on the side of the first fastening strap 2 away from the end cap 1, a second left fastening strap 31 extending to the left and a second right fastening strap 32 extending to the right being provided on the side of the second fastening strap 3 away from the end cap 1, the first left fastening strap 21 and the second left fastening strap 31 being used to be wrapped around the left side of the pipe and detachably connected to each other, the first right fastening strap 22 and the second right fastening strap 32 being used to be wrapped around the right side of the pipe and detachably connected to each other.

[0026] The above scheme arranges the first fastening band 2 and the second fastening band 3 on the upper side and the lower side of the end cover 1 respectively, so that after the end cover 1 is plugged into the pipe opening, the first fastening band 2 and the second fastening band 3 are respectively attached to the upper side and the lower side of the pipe, and then the first left tie 21 and the second left tie 31 are wrapped around the left side of the pipe and connected to each other, and the first right tie 22 and the second right tie 32 are wrapped around the right side of the pipe and connected to each other. At this time, the first fastening band 2 and the second fastening band 3 are wrapped around and fixed relative to the pipe, and the end cover 1 is fixed relative to the pipe opening. Compared with the prior art, the above scheme fixes the end cover 1 relative to the pipe opening by wrapping and fixing the first fastening band 2 and the second fastening band 3 relative to the pipe. It is not only simple and convenient to operate, but also can be repeatedly disassembled and used. In addition, it does not require additional tools and does not require processing of the pipe structure itself, and has good practicality.

[0027] As an improvement to the above embodiment, a raised clamping platform 11 is provided on the end face of the end cap 1 facing the pipe opening. The clamping platform 11 is annular and is used to be inserted into the pipe opening, thereby achieving a better blocking effect of the end cap 1 on the pipe opening. The clamping platform 11 is preferably in the shape of a circular ring so as to be adaptable to most pipe opening shapes. Furthermore, the upper and lower side walls of the clamping platform 11 are provided with a raised fastening layer 12, and the fastening layer 12 is made of an elastic material, such as rubber. Since the first fastening belt 2 and the second fastening belt 3 are respectively provided on the upper and lower sides of the end cap 1, the upper and lower parts of the end cap 1 will be subjected to a more direct tensile force. Therefore, by providing the fastening layer 12 on the upper and lower side walls of the clamping platform 11, a greater frictional resistance can be generated between the fastening layer 12 and the inner wall of the pipe after the clamping platform 11 is inserted into the pipe opening, thereby achieving a more stable blocking effect of the end cap 1 on the pipe opening.

[0028] In this embodiment, the first fastening belt 2 and the second fastening belt 3 are both made of flexible material. The first left tie 21 and the first right tie 22 are both provided with a plurality of locking teeth 4 distributed in the left and right directions on the side facing away from the pipe. The left end of the second left tie 31 and the right end of the second right tie 32 are both provided with a snap-fitting member 5. The snap-fitting member 5 is used to snap-fit ​​with the locking teeth 4. Thus, the snap-fitting member 5 of the second left tie 31 and the second right tie 32 can realize the mutual connection between the first fastening belt 2 and the second fastening belt 3 by snap-fitting with the locking teeth 4 of the first left tie 21 and the second right tie 32 respectively. More specifically, the snap-fitting member 5 includes a frame shell 51, a short shaft 52 and an elastic locking tongue 53. Figure 5 As a reference, the short shaft 52 is connected to the frame shell 51 in the vertical direction. The middle part of the elastic locking tongue 53 is connected to the short shaft 52. One end of the elastic locking tongue 53 is located below the short shaft 52 and the other end is located above the short shaft 52, so that the elastic locking tongue 53 is arranged at an angle. The left side of the frame shell 51 located at the second left tie 31 is provided with a first opening 511 for inserting the first left tie 21, and the upper end surface is provided with a second opening 512 arranged opposite the elastic locking tongue 53. The right side of the frame shell 51 located at the second right tie 32 is provided with a first opening 511 for inserting the first right tie 22, and the upper end surface is provided with a second opening 512 arranged opposite the elastic locking tongue 53. After adopting this structure, by inserting the first left tie 21 into the first opening 511 of the frame shell 51 of the second left tie 31, the corresponding elastic locking tongue 53 at one end below the short axis 52 can abut against the locking tooth 4 of the first left tie 21, thereby realizing the connection between the first left tie 21 and the second left tie 31; and when it is necessary to release the connection between the first left tie 21 and the second left tie 31, it is only necessary to push the elastic locking tongue 53 at one end above the short axis 52 from the second opening 512, and the elastic locking tongue 53 can be separated from the locking tooth 4 based on the lever principle; the same applies to the first right tie 22 and the second right tie 32.

[0029] Further, such as Figure 7 and Figure 8As shown, in another embodiment, the frame 51 is provided with a cover 54 having the same shape as the second opening 512. In this embodiment, one side of the cover 54 is rotatably connected to the frame 51, and the other side of the cover 54 is provided with a hook 541. The outer side of the frame 51 is provided with a block 55 for the hook 541 to engage. Thus, the cover 54 closes the second opening 512, preventing the elastic locking tongue 53 from being accidentally touched. Of course, the cover 54 and the frame 51 can also be connected in other ways, such as a sliding connection, as long as the cover 54 can close the second opening 512.

[0030] As an improvement to the above embodiment, the first fastening band 2 and the second fastening band 3 are both provided with anti-slip marks 6 on the side facing the pipeline. The anti-slip marks 6 are concave-convex structures, thereby increasing the friction resistance of the first fastening band 2 and the second fastening band 3 relative to the pipeline, ensuring a more stable blocking effect of the end cover 1 on the pipeline opening.

[0031] Although the present disclosure is disclosed as above, the protection scope of the present disclosure is not limited thereto. For those skilled in the art, various changes and modifications can be made without departing from the spirit and scope of the present disclosure, and these changes and modifications will fall within the protection scope of the invention.
