Description

Technical Field

[0001] The invention belongs to the technical field of pipelines, and in particular relates to a pipeline plugging device with stable installation. Background Art

[0002] The pipeline sealing device is mainly used to seal the gap between cables and pipes and walls. While improving the stability of cables and pipes during use, it also reduces dust from passing through the gap and entering the other side of the wall.

[0003] The pipeline plugging device includes a sleeve part, which is pre-installed on the wall. The pipeline is fixed after passing through the sleeve. This type of pipeline plugging device is widely used due to its simple structure. However, in actual use, the above pipeline plugging device still has the following disadvantages: (1) poor adaptability. The sleeve needs to be perfectly matched with the size of the pipeline, otherwise the pipeline is easy to move after being fixed; (2) poor stability. Since the sleeve is only fixed by contact with the pipeline, when the pipeline is subjected to tension, it is easy to move relative to the sleeve. Summary of the invention

[0004] The existing pipeline plugging device needs to improve its adaptability during installation and stability after installation. To this end, the following invention is proposed:

[0005] A pipeline plugging device with stable installation comprises a main sleeve and an auxiliary sleeve detachably connected to the main sleeve, wherein the main sleeve and the auxiliary sleeve are provided with a first through hole, a fixing clamp and drive expansion plates at both ends of the fixing clamp are provided in the first through hole, the fixing clamp comprises a plurality of clamps arranged in a ring shape and an annular sleeve spring elastically sleeved on the outside of the clamps to fix the clamps to each other, a through clamp groove is provided at the center of the fixing clamp, driven heads are provided at both ends of the clamps, a second through hole is provided at the center of the drive expansion plate, and after the drive expansion plate moves toward the driven head, it presses all the clamps at the same time and drives them to move outward to expand the clamp groove outward.

[0006] The fixing clamp is initially pressed by the drive expansion plate, and its internal clamping plate elastically expands outward. After the cable and the pipeline pass through the first through hole and are installed in the second through hole, the drive expansion plate is moved outward so that the clamping plate fits with the cable and the pipeline, thereby clamping the pipeline, reducing the shaking of the pipeline, improving its stability, and being adaptable to pipelines of various sizes for easy use.

[0007] Furthermore, the main sleeve is provided with a connection groove, the auxiliary sleeve is provided with a connection column threadedly connected to the connection groove, a cavity is formed between the connection groove and the connection column, and an arc plate is provided on the outer side of the clamping plate to be inserted into the cavity, and the arc plate is blocked by both sides of the cavity to limit the horizontal movement of the clamping plate in the first through hole. The arc plate prevents the clamping plate from moving with the pipeline when it is pulled horizontally, thereby providing a more stable clamping fixation for the pipeline.

[0008] Furthermore, the drive expansion plate is provided with a drive expansion surface extending obliquely toward the fixed clamp, and the inner side of the driven head is provided with a driven surface extending obliquely toward the drive expansion plate. After the drive expansion plate moves toward the fixed clamp, the drive expansion surface contacts the inner side of the driven surface to drive the clamp plate to move outward. By adjusting the position of the drive expansion plate in the first through hole, the fixed clamp can be in contact with the pipeline and the drive expansion surface at the same time. Due to the contraction force of the peripheral spring and the contact of the drive expansion platform, the pipeline is difficult to move in the first through hole and is relatively stable.

[0009] Furthermore, the drive expansion plate is also provided with a rotating table threadedly connected to the first through hole, and a plurality of rotating holes are provided on the outer side surface of the rotating table. The rotating table can be conveniently rotated using a tool matching the rotating holes to drive the drive expansion plate to rotate in or out of the first through hole.

[0010] Furthermore, a ring groove is provided on the outer side of the clamping plate, and the ring sleeve spring is arranged in the ring groove to stably set the ring sleeve spring on the clamping plate to reduce its deviation.

[0011] Optionally, a sealant is provided on the inner side of the clamp, and after the clamp is fitted to the pipeline, the sealant fits tightly to further reduce shaking of the pipeline relative to the fixing clamp.

[0012] Optionally, the inner side of the clamping plate is provided with a plurality of fixing spikes extending into the clamping groove, and the fixing spikes can be used in combination with sealant or alone to irreversibly fix the cable by piercing the outer skin of the cable, but the stability is better than that of sealant.

[0013] The present invention proposes a pipeline sealing device with stable installation, which is provided with a fixing clamp and a drive expansion plate in a first through hole. By controlling the position of the drive plate in the first through hole, the fixing clamp can be opened or contracted, and the fixing clamp clamps the pipeline passing through the first through hole after contraction. Compared with the previous pipeline sealing devices, the beneficial effect of the present invention is that the fixing clamp can be contracted and expanded, so that it has a higher degree of adaptability to pipelines of different sizes, and the pipeline is clamped and fixed by contracting inwardly through a ring sleeve spring, thereby reducing the movement of the pipeline in the first through hole and improving the overall stability.

[0020] The technical solution of the present invention will be clearly and completely described below in conjunction with embodiments.

[0021] Based on the embodiments in this application, all other embodiments obtained by ordinary technicians in this field without making any creative work should fall within the scope of protection of this application.

[0022] In addition, the terms "comprises," "comprising," and "having," and any variations thereof, are intended to cover non-exclusive inclusions.

[0023] In the present application, the terms "upper", "lower", "left", "right", "front", "back", "top", "bottom", "inner", "outer", "middle", "vertical", "horizontal", "lateral", "longitudinal" and the like indicate positions or positional relationships based on the positions or positional relationships shown in the drawings. These terms are mainly used to better describe the present invention and its embodiments, and are not used to limit the indicated devices, elements or components to have a specific orientation, or to be constructed and operated in a specific orientation.

[0024] like Figure 1-Figure 2As shown, it is a preferred embodiment of the present invention, a pipeline plugging device with stable installation, comprising a main casing 1 and an auxiliary casing 2, wherein one end of the main casing 1 is provided with a baffle 13 extending toward the periphery, and the other end is provided with a connecting groove 11 with an opening toward the auxiliary casing 2, one end of the auxiliary casing 2 is provided with a baffle 13 extending toward the periphery, and the other end is provided with a connecting column 21 extending toward the auxiliary casing 2, the connecting column 21 is threadedly connected in the connecting groove 11 to detachably fix and connect the main casing 1 and the auxiliary casing 2, and a first through hole 12 penetrating therethrough is provided on both the main casing 1 and the auxiliary casing 2,

[0025] like Figure 2-Figure 3 As shown, a fixing clamp 3 and a drive expansion plate 4 are provided in the first through hole 12. The drive expansion plate 4 is provided with two, which are respectively provided on both sides of the drive expansion plate 4. The fixing clamp 3 includes a plurality of clamps 31 and a ring spring 32. The clamps 31 are arranged in a ring shape as a whole and a clamp groove 39 is formed at the center. The ring spring 32 is elastically sleeved on the outer sides of the two ends of the clamps 31 to fix the clamps 31 to each other and limit the clamps 31 from moving outward. A second through hole 44 is provided at the center of the drive expansion plate 4, and the pipeline 5 passes through the first through hole 12. When the ring spring 32 is not deformed outward, the clamp groove 39 is in an initial state, and its radius is smaller than the second through hole 44. A driven head 35 is also provided at both ends of the clamp 31. The end of the drive expansion plate 4 enters the inner side of the driven head 35. The second through hole 44 and the clamp groove 39 are connected and are both located in the first through hole 12.

[0026] The drive expansion plate 4 can move horizontally in the first through hole 12. After the two drive expansion plates 4 move toward the fixed clamp 3, they enter the inner side of the driven head 35 and continue to move until the drive expansion plate 4 presses the driven head 35 from the inside. The clamp 31 moves outward due to the outward resistance of the driven heads 35 at both ends. The annular spring 32 elastically expands outward, and the clamping groove 39 also expands outward at the same time. When the clamping groove 39 is expanded to a size not less than the second through hole 44, the movement of the drive expansion plate 4 is stopped. After the main sleeve 1 and the auxiliary sleeve 2 are both installed on the wall, the pipeline 5 with a size between the initial state of the clamping groove 39 and the second through hole 44 is passed through the second through hole 44. After the pipeline 5 passes through the specified position, the two expansion plates 4 are moved outward. After losing the outward pressure of the expansion plate 4, the clamping plate 31 moves inward to fit the pipeline 5, and the clamping groove 39 shrinks to a radius suitable for the pipeline 5, so as to clamp the pipeline 5 and the expansion plate 4 at the same time. The movement of the pipeline 5 requires the fixing clamp 3 to expand outward, and the fixing clamp 3 needs to overcome the resistance of the ring spring 32, thereby achieving the fixation of the pipeline 5.

[0027] When the pulling force applied to the pipeline 5 in the horizontal direction is relatively large, the clamping plate 31 will still move horizontally with the pipeline 5 and will be resisted by the expansion plate 4, thereby expanding the clamping groove 39. After the clamping groove 39 expands, the pipeline 5 can move horizontally out of the second through hole 44. To solve this problem, a cavity is formed between the connecting groove 11 and the connecting column 21. An arc plate 34 is provided on the outer side of the clamping plate 31 to be inserted into the cavity. The arc plate 34 is blocked by both sides of the cavity to limit the horizontal movement of the clamping plate 31 in the first through hole 12, thereby preventing the pipeline 5 from moving horizontally outward due to pulling.

[0028] Specifically, a driving expansion surface 41 extending obliquely toward the fixing clamp 3 is provided on the driving expansion plate 4, and a driven surface 36 extending obliquely toward the driving expansion plate 4 is provided on the inner side of the driven head 35. After the driving expansion plate 4 moves toward the fixing clamp 3, the driving expansion surface 41 contacts the inner side of the driven surface 36 to drive the clamping plate 31 to move outward. In actual use, once the driving expansion plate 4 is installed, the driving expansion surface 41 is always in contact with the driven surface 36 to prevent the fixing clamp 3 from moving freely in the first through hole 12.

[0029] In this embodiment, the drive and expansion plate 4 is also provided with a rotating table 42 threadedly connected to the first through hole 12, and a plurality of rotating holes 43 are provided on the outer surface of the rotating table 42. After a tool matching the rotating holes 43 is inserted, the rotating table 42 can be rotated, and then the drive and expansion plate 4 is driven to rotate. After the drive and expansion plate 4 is rotated, it is screwed in or out of the first through hole 12. Since the drive and expansion plate 4 is threadedly connected to the first through hole 12, it is prevented from spontaneously moving outward due to the pressure of the fixing clamp 3. The drive and expansion plate 4 is also arranged so that when its outer end face is flush with the outer side face of the baffle 13, the clamping plate 31 only contacts the drive and expansion plate 4 without being pressed by it; further, a ring groove 33 is provided on the outer side of the clamping plate 31, and the ring sleeve spring 32 is cooperatively arranged in the ring groove 33 to prevent the ring sleeve spring 32 from deflecting.

[0030] like Figure 4As shown, on the basis of the above, a sealant 37 or a plurality of fixing spikes 38 extending into the clamping groove 39 are provided on the inner side of the clamping plate 31. After the sealant 37 is fitted with the pipeline 5, it prevents the pipeline 5 from moving relative to the clamping plate 31 and reduces the gap between the pipeline 5 and the sealant 37. If it is necessary to repeatedly disassemble the pipeline 5, the sealant 37 can be replaced with a sealing rubber; when setting the fixing spike 38, the fixing spike 38 and the sealant 37 can be set together. At this time, the fixing spike 38 extends from the inner side of the clamping plate 31 and penetrates the sealant 37. The fixing spike 38 can also be set separately. It should be particularly noted that, on the one hand, the setting of the fixing spike 38 will cause damage to the outer side of the pipeline 5 and make it difficult to reversibly disassemble the pipeline 5. On the other hand, when the fixing spike 38 is set, when the pipeline 5 passes through the second through hole 44, it is necessary to drive the clamping plate 31 to move outward by an increased distance, thereby reducing the range of pipeline 5 sizes that the fixing clamp 3 can adapt to. In addition, when the pipeline 5 does not match the initial state of the clamping groove 39, a gap will appear between the clamping plates 31 after they move outward. This gap will be connected to the annular gap between the second through hole 44 and the pipeline 5. In order to improve the sealing performance and stability, plasticine can be used between the annular gaps.

[0031] The above is only a specific implementation of the present application, but the protection scope of the present application is not limited thereto. Any person skilled in the art who is familiar with the present technical field can easily think of changes or substitutions within the technical scope disclosed in the present application, which should be included in the protection scope of the present application. Therefore, the protection scope of the present application should be based on the protection scope of the claims.
