Description

Technical Field

[0001] This utility model relates to the field of corrugated pipe technology, and in particular to a lightweight steel strip reinforced corrugated pipe. Background Technology

[0002] A search revealed a lightweight steel-reinforced corrugated pipe with publication number CN221374839U. By setting internal and external connecting pipes inside and outside the steel-reinforced corrugated pipe, the internal and external connecting pipes can be used to connect and fix the steel-reinforced corrugated pipe at the same time, which increases the strength and stability of the connection part, improves the sealing of the connection part, and increases the service life of the steel-reinforced corrugated pipe.

[0003] In the process of realizing this invention, the inventors discovered at least the following problems in the prior art: the inner and outer pipes can ensure a certain degree of stability in the connection process of steel strip corrugated pipes. However, the main function of this connection structure is to improve stability, and the effect on enhancing sealing is minimal. Even under ideal conditions, when the first steel strip corrugated pipe and the second steel strip corrugated pipe are tightly fitted by the connection structure, it is difficult to fundamentally eliminate the risk of leakage. Although in the initial stage, high processing precision may achieve no leakage for a short period of time, as the usage time goes on, due to the lack of a continuous and effective support structure at the interface, the fit at the interface gradually changes under the influence of factors such as long-term internal medium pressure fluctuations, external environmental stress, and possible vibration and impact, which may eventually lead to leakage.

[0004] Therefore, the aforementioned technical problems need to be solved. Utility Model Content

[0005] In order to overcome the shortcomings of the existing technology, the basic technical solution proposed by this utility model is: a lightweight steel strip reinforced corrugated pipe, including a corrugated pipe body, wherein the two ends of the corrugated pipe body are provided with connection structures that facilitate connection with other corrugated pipes.

[0006] The connection structure includes a fixed sleeve located at the right end of the corrugated pipe body and a plug-in sleeve located at the left end of the corrugated pipe body, as well as four movable frames installed outside the plug-in sleeve and arranged in a ring. The inner walls of the four movable frames are provided with n-shaped grooves, and the inner walls of the n-shaped grooves are slidably connected to sliders.

[0007] Preferably, a movable ring is fixedly connected to the outside of the slider, and a connecting block is fixedly connected to the left end of the movable ring.

[0008] Preferably, a sealing ring is installed at the left end of the connecting block to support the interface of the two mating bellows bodies.

[0009] Preferably, the inner walls of the n-shaped grooves are rotatably connected to limit rods, which are used to limit the movement range of the slider.

[0010] Preferably, the fixing sleeve is threadedly connected to the right end of the outer wall of the bellows body via an internal thread, and the insertion sleeve is threadedly connected to the left end of the outer wall of the bellows body via an internal thread.

[0011] Preferably, two extension blocks are welded to the outside of the fixing sleeve, and the inner walls of the two extension blocks are provided with screws, so that the fixing sleeve is also locked to the outside of the bellows body by the screws.

[0012] The beneficial effects of this utility model are:

[0013] Through the design of the connection structure, a stable and operable connection base is formed by installing the fixed sleeve and the plug sleeve at both ends of the bellows body. During the splicing process, rotating the limit rod creates conditions for the sliding of the slider. Then, rotating the movable ring allows the slider to slide smoothly in the n-shaped groove. Pulling the movable ring to the left moves the connecting block and the sealing ring into the fixed sleeve and finally to one end of the bellows body. At this time, the other bellows body extends through the plug sleeve to abut against the current bellows body. Because the sealing ring fits tightly against the bellows body interface, it effectively fills the connection gap, greatly enhances the sealing performance, and can effectively prevent media leakage. In addition to enhancing the seal, the sealing ring also provides additional support for the interface, which can effectively resist the interface deformation caused by external forces, changes in media pressure, etc., and avoid the interface loosening and deterioration of sealing performance after long-term use.

[0020] The following will be combined with the appendix Figure 1 To be continued Figure 4 The technical solutions in the embodiments of this utility model are clearly and completely described. Obviously, the described embodiments are only a part of the embodiments of this utility model, and not all of them. Based on the embodiments of this utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of this utility model.

[0021] It should be noted that, in the embodiments of this utility model, the directions shown in the accompanying drawings shall prevail, such as front and back. Figure 1 For the sake of accuracy, the specific details should be as follows: Figure 1 The left side is the front. Figure 1 The right side is the rear; at the same time, as Figure 2 As shown, the horizontal direction is roughly defined as left and right, and the vertical direction is defined as up and down. If a specific orientation changes, the directional indication will also change accordingly.

[0022] Example 1

[0023] Please see Figure 1 - Figure 4 As shown, this embodiment provides a lightweight steel strip reinforced corrugated pipe, including a corrugated pipe body 1, and the two ends of the corrugated pipe body 1 are provided with connection structures 2 for easy connection with other corrugated pipes;

[0024] The connecting structure 2 includes a fixed sleeve 21 located at the right end of the bellows body 1 and a plug-in sleeve 22 located at the left end of the bellows body 1, as well as four movable frames 23 installed on the outside of the plug-in sleeve 22 and arranged in a ring. The inner walls of the four movable frames 23 are provided with n-shaped grooves, and sliders 24 are slidably connected to the inner walls of the n-shaped grooves.

[0025] This invention addresses the issue that while existing structures provide additional support during splicing, the sealing effect at the joint between two bellows remains inadequate. Therefore, the design of the connecting structure 2, by installing the fixing sleeve 21 and the insertion sleeve 22 at both ends of the bellows body 1, creates a stable and operable connection base. During splicing, rotating the limiting rod 28 creates conditions for the sliding of the slider 24. Subsequently, rotating the movable ring 25 allows the slider 24 to slide smoothly within the n-shaped groove. Pulling the movable ring 25 to the left moves the connecting block 26 and the sealing... The sealing ring 27 enters the fixing sleeve 21 and finally reaches one end of the bellows body 1. At this time, another bellows body 1 extends through the plug sleeve 22 to abut against the current bellows body 1. Since the sealing ring 27 fits tightly against the interface of the bellows body 1, it effectively fills the connection gap and greatly enhances the sealing performance, which can effectively prevent media leakage. In addition to enhancing the seal, the sealing ring 27 also provides additional support for the interface, which can effectively resist the interface deformation caused by external force, changes in media pressure, etc., and avoid the interface loosening and deterioration of sealing performance after long-term use.

[0026] Example 2

[0027] like Figure 2 - Figure 4 As shown, a movable ring 25 is fixedly connected to the outside of the slider 24. A connecting block 26 is fixedly connected to the left end of the movable ring 25. A sealing ring 27 for supporting the interface of the two mating bellows bodies 1 is installed on the left end of the connecting block 26. Limiting rods 28 are rotatably connected to the inner walls of the n-shaped grooves. The limiting rods 28 are used to limit the movement range of the slider 24. The fixed sleeve 21 is threaded to the right end of the outer wall of the bellows body 1 through an internal thread. The insertion sleeve 22 is threaded to the left end of the outer wall of the bellows body 1 through an internal thread. In addition, two extension blocks 211 are welded to the outside of the fixed sleeve 21, and the inner walls of the two extension blocks 211 are provided with screws, so that the fixed sleeve 21 is also locked to the outside of the bellows body 1 by the screws. The extension blocks 211 welded to the outside of the fixed sleeve 21 and the screw locking design further enhance the connection strength between the fixed sleeve 21 and the bellows body 1, so that the entire connection structure 2 can remain stable when subjected to external tension, pressure and vibration, effectively preventing the connection from loosening or falling off, and greatly improving the reliability of the pipeline system during long-term use.

[0028] The sealing ring 27 fits tightly against the interface when the two bellows bodies 1 are joined. On the one hand, it significantly enhances the sealing performance of the interface and effectively prevents leakage of liquid, gas and other media. It is suitable for a variety of engineering environments with strict sealing requirements. On the other hand, it provides additional support for the interface and can resist the deformation of the interface caused by media pressure, external load and other factors.

[0029] Work steps;

[0030] First, for each corrugated pipe body 1 to be spliced, components need to be installed at both ends. The fixing sleeve 21 is tightly screwed onto the outer wall of one end of the corrugated pipe body 1 using its internal thread, and the insertion sleeve 22 is screwed onto the outer wall of the other end using its internal thread, preparing for subsequent splicing. The limiting rod 28 on the inner wall of the n-shaped groove of the movable frame 23 is rotated to allow the slider 24 to slide freely. The movable ring 25 is rotated; since the slider 24 is fixedly connected to the movable ring 25, the slider 24 will slide smoothly within the n-shaped groove. Pulling the movable ring 25 to the left moves the connected components. Block 26 and sealing ring 27 move together until they enter the corresponding fixing sleeve 21 and reach one end of the bellows body 1. Align one end of the insertion sleeve 22 of another bellows with one end of the fixing sleeve 21 of the bellows that has completed the above operation, and slowly insert it so that the two bellows initially come into contact. Rotate the limiting rod 28 to reset, limiting the movement range of the slider 24 and preventing it from sliding accidentally during use. At this time, the sealing ring 27 fits tightly against the interface of the two bellows bodies 1, which not only enhances the sealing performance and effectively prevents media leakage, but also provides additional support for the interface.

[0031] Based on the disclosure and teachings of the above specification, those skilled in the art can make changes and modifications to the above embodiments. Therefore, this utility model is not limited to the specific embodiments disclosed and described above, and some modifications and changes to this utility model should also fall within the protection scope of the claims of this utility model. Furthermore, although some specific terms are used in this specification, these terms are only for convenience of explanation and do not constitute any limitation on this utility model.
