Abstract
Description
Technical Field
[0001] This utility model relates to the field of pipe connection technology, and more specifically, to a pipe connection device that facilitates pipe replacement. Background Technology
[0002] In daily work, welding or pipe connection devices are often used to connect two pipe sections. However, pipe welding requires strict welding skills and is slow, making it impossible to connect two pipe sections quickly, resulting in low work efficiency. Furthermore, when using pipe connection devices, the angles between the pipes to be connected often vary due to actual installation adjustments, requiring the customization of numerous pipe connection devices with different angles. This leads to poor applicability and high costs. To address these issues, we propose a pipe connection device for pipeline engineering.
[0003] Therefore, we have made improvements to this by proposing a pipe connection device that facilitates pipe replacement. Utility Model Content
[0004] The purpose of this utility model is to solve the problems of poor applicability and high cost of current pipe connection devices.
[0005] To achieve the above-mentioned objectives and improve the aforementioned problems, this utility model provides a pipe connection device that facilitates pipe replacement, comprising a corrugated pipe, with a first connecting pipe and a second connecting pipe fixedly connected to both ends of the corrugated pipe, and a flange fixedly connected to the ends of the first and second connecting pipes away from the corrugated pipe. A second rotating ring and a first rotating ring are rotatably connected to the surfaces of the first and second connecting pipes, respectively. The second rotating ring and the first rotating ring are both connected to the first and second connecting pipes via bearings. A first reinforcing rod is slidably connected inside the second rotating ring, penetrating the surface of the second rotating ring. A second reinforcing rod is slidably connected inside the first rotating ring, penetrating the surface of the first rotating ring. A connecting ball and a spherical shell are fixedly connected to the opposite ends of the first and second reinforcing rods, respectively, with the connecting ball located inside the spherical shell.
[0006] As a preferred technical solution of this application, the inner wall of the second rotating ring is provided with a cover, the cover is connected to the second rotating ring by screws, and the first reinforcing rod also passes through the surface of the cover and is slidably connected to the inside of the cover.
[0007] As a preferred technical solution of this application, a worm gear is fixedly connected to the surface of the second rotating ring, a fixed shell is fixedly connected to the surface of the first connecting pipe, the second rotating ring slides through the surface of the fixed shell and is slidably connected to the inside of the fixed shell, and a worm is rotatably connected to the inside of the fixed shell, and the worm meshes with the worm gear.
[0008] As a preferred technical solution of this application, a plurality of extrusion balls are placed inside the second rotating ring, and a threaded rod is threadedly connected to the bottom of the second rotating ring. An insertion ball is fixedly connected to one end of the threaded rod located inside the second rotating ring.
[0009] As a preferred technical solution of this application, a rubber sleeve is provided on the surface of the first reinforcing rod.
[0010] As a preferred technical solution of this application, the interior of the first rotating ring is also provided with a compression ball, a insertion ball, a threaded rod and a cap.
[0011] Compared with the prior art, the beneficial effects of this utility model are as follows:
[0012] In the scheme of this application:
[0013] 1. By setting the corrugated pipe, the angles of the first connecting pipe and the second connecting pipe can be adjusted at will, which solves the problem that in the existing technology, when connecting pipes, the angles of the two pipes to be connected often have different angles due to actual installation and adjustment, resulting in poor applicability of the existing pipe connection device;

[0021] To enable those skilled in the art to better understand the present invention, the technical solutions of the present invention will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort should fall within the protection scope of the present invention.
[0022] To enable those skilled in the art to better understand the present invention, the technical solutions in the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings.
[0023] It should be noted that, unless otherwise specified, the embodiments and features and technical solutions in the present invention can be combined with each other.
[0024] It should be noted that similar labels and letters in the following figures indicate similar items. Therefore, once an item is defined in one figure, it does not need to be further defined and explained in subsequent figures.
[0025] Please refer to Figure 1 , Figure 2 , Figure 3 and Figure 4 A pipe connection device for easy pipe replacement includes a corrugated pipe 1, with a first connecting pipe 2 and a second connecting pipe 3 fixedly connected to both ends of the corrugated pipe 1 for connecting two pipes to be connected. Flanges are fixedly connected to the ends of the first connecting pipe 2 and the second connecting pipe 3 away from the corrugated pipe 1 to facilitate connection between the first connecting pipe 2 and the second connecting pipe 3 and the pipes to be connected. The corrugated pipe 1 allows the first connecting pipe 2 and the second connecting pipe 3 to rotate at multiple angles, enabling adjustment of the angle between the first connecting pipe 2 and the second connecting pipe 3 according to the actual angles of the two pipes to be connected. This allows the first connecting pipe 2 and the second connecting pipe 3 to connect with pipes at different angles, improving the applicability of the device.
[0026] A second rotating ring 5 and a first rotating ring 4 are rotatably connected to the surfaces of the first connecting pipe 2 and the second connecting pipe 3, respectively. Both the second rotating ring 5 and the first rotating ring 4 are connected to the first connecting pipe 2 and the second connecting pipe 3 through bearings. A first reinforcing rod 7 is slidably connected inside the second rotating ring 5, penetrating the surface of the second rotating ring 5. A second reinforcing rod 15 is slidably connected inside the first rotating ring 4, penetrating the surface of the first rotating ring 4. A connecting ball 16 and a spherical shell 11 are fixedly connected to the opposite ends of the first reinforcing rod 7 and the second reinforcing rod 15, respectively. The connecting ball 16 is located inside the spherical shell 11. Thus, through the arrangement of the connecting ball 16 and the spherical shell 11, the first reinforcing rod 7 and the second reinforcing rod 15 can rotate accordingly according to the bending angle of the bellows 1, ensuring the smooth operation of the device.
[0027] The inner wall of the second rotating ring 5 is provided with a cover 8, which is connected to the second rotating ring 5 by screws. The first reinforcing rod 7 also passes through the surface of the cover 8 and is slidably connected to the inside of the cover 8. The surface of the second rotating ring 5 is fixedly connected with a worm gear 6, and the surface of the first connecting tube 2 is fixedly connected with a fixed shell 9. The second rotating ring 5 passes through the surface of the fixed shell 9 and is slidably connected to the inside of the fixed shell 9. The inside of the fixed shell 9 is rotatably connected with a worm 10, which meshes with the worm gear 6. Thus, the rotation angle of the second rotating ring 5 can be locked by the worm 10 and the worm gear 6, which prevents the second rotating ring 5 and the first rotating ring 4 from rotating arbitrarily and ensures the stability of the device during use.
[0028] The second rotating ring 5 contains multiple compression balls 12. A threaded rod 14 is threadedly connected to the bottom of the second rotating ring 5. An insert ball 13 is fixedly connected to one end of the threaded rod 14 inside the second rotating ring 5 to compress the compression balls 12 in the second rotating ring 5, thereby indirectly compressing the first reinforcing rod 7. This prevents the first reinforcing rod 7 from sliding freely after the device is locked, which would affect the stability of the device. A rubber sleeve is provided on the surface of the first reinforcing rod 7 to increase the friction between the compression balls 12 and the first reinforcing rod 7, thereby improving the device's restraining effect on the first reinforcing rod 7. The first rotating ring 4 also contains compression balls 12, insert balls 13, threaded rod 14, and a cap 8.
[0029] The pipe connection device for easy pipe replacement provided by this utility model is used as follows: First, based on the angles of the two pipes to be connected, the angle between the first connecting pipe 2 and the second connecting pipe 3 is bent. During the bending process, the connecting ball 16 and the ball shell 11 between the second reinforcing rod 15 and the first reinforcing rod 7 rotate accordingly due to the bending of the bellows 1. Simultaneously, due to the change in the angles of the first connecting pipe 2 and the second connecting pipe 3, the first reinforcing rod 7 and the second reinforcing rod 15 slide against the second rotating ring 5 and the first rotating ring 4, respectively. Next, after the angles of the first connecting pipe 2 and the second connecting pipe 3 are determined, the operator can drive the threaded rods 14 to gradually screw in by rotating the two threaded rods 14 in sequence. In the second rotating ring 5, the insert ball 13 is squeezed between two adjacent extrusion balls 12, thereby extrusion balls 12 compress and fix the first reinforcing rod 7 and the second reinforcing rod 15, preventing the first reinforcing rod 7 and the second reinforcing rod 15 from sliding again. At the same time, due to the locking of the length of the first reinforcing rod 7 and the second reinforcing rod 15, the angle of the first connecting pipe 2 and the second connecting pipe 3 no longer changes, thus ensuring the stability of the device during use. Then, the operator can connect the flanges on the first connecting pipe 2 and the second connecting pipe 3 to the two pipes to be connected in sequence. Since the first connecting pipe 2 and the second connecting pipe 3 are connected to the pipes to be connected using conventional flanges, the operator can use a conventional wrench to disassemble and assemble the device, so as to facilitate the connection of the device to different pipes.
