[0018] To facilitate understanding of this utility model, a more comprehensive description of the utility model will be provided below, along with preferred embodiments. However, this utility model can be implemented in many different forms and is not limited to the embodiments described herein. Rather, these embodiments are provided to enable a more thorough and complete understanding of the disclosure of this utility model.

[0019] Unless otherwise defined, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention pertains. The terminology used herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the invention.

[0020] Example: See Figures 1-3 This embodiment provides a fastening ring for pipe splicing, comprising a clamp 11, a locking buckle 12, and locking posts 13. The two ends of the locking buckle 12 are fixedly connected to the two ends of the clamp 11, and the locking buckle 12 is used to lock the two ends of the clamp 11. The locking buckle 12 can be opened. When it is necessary to tighten the clamp 11 to the outer wall of the pipe, the locking buckle 12 is opened, the clamp 11 is wrapped around the outer circumference of the pipe, and the locking buckle 12 is locked to tighten the clamp 11 to the outer surface of the pipe. Two locking posts 13 are arranged, and the two locking posts 13 are fixedly connected to the outside of the clamp 11. When the clamp 11 is in the locked state and forms a ring, the two locking posts 13 are located on both sides of the radial direction of the ring clamp 11.

[0021] Specifically, in use, two sets of pipe splicing fastening rings are required. One set of pipe splicing fastening rings has a clamp 11 that is fastened to the outer circumference of the pipe to be installed via a locking buckle 12. The other set of pipe splicing fastening rings has a clamp 11 that is fastened to the outer circumference of the already installed pipe via a locking buckle 12. When tightening the two clamps 11, the locking posts 13 on both sides of the clamps 11 are in a horizontal position, and the locking posts 13 on the two sets of clamps 11 are aligned. Then, two hydraulic cylinders with locking interfaces at both ends are respectively engaged with the four locking posts 13 on both sides of the two sets of clamps 11. When the hydraulic cylinders retract, they drive the two sets of pipe splicing fastening rings to move closer together. Because the already installed pipe is fixed, the retraction of the hydraulic cylinders actually pulls the pipe to be installed toward the already installed pipe, thus inserting the pipe to be installed into the already installed pipe, achieving the installation of the pipe to be installed.

[0022] With the above structural design, during pipeline installation, two sets of pipes are spliced ​​together and secured to the pipe to be installed and the already installed pipe respectively using fastening clasps. Then, a hydraulic cylinder is used to engage with the locking pin 13 on the clamp 11. When the hydraulic cylinder retracts, it moves the pipe to be installed and inserts it into the already installed pipe, thus completing the installation of the pipe to be installed. The entire installation process is quick and does not require the assistance of external cranes or excavators. It enables construction in confined spaces, improving construction efficiency, reducing construction costs, and enhancing economic benefits.

[0023] It should also be noted that a cylinder or an electric telescopic rod can also be used to pull the fastening rings for splicing the two pipes. The cylinder or electric telescopic rod can also drive the fastening rings for splicing the two pipes closer to each other, so as to realize the installation of the pipes in a confined space.

[0024] Preferably, the hoop 11 is further provided with a support portion 111. The support portion 111 extends laterally along the hoop 11. Specifically, when the hoop 11 is formed into a ring, the extension direction of the support portion 111 is parallel to the axial direction of the ring. Two support portions 111 are provided, and the two support portions 111 are arranged corresponding to two locking posts 13. The support portions 111 are located laterally to the locking posts 13, and the two support portions 111 are located on the same side of the hoop 11.

[0025] It should be noted that when the hydraulic cylinder retracts, it pulls the locking pin 13 to move. At this time, the locking pin 13 is subjected to torque, which is transmitted to the clamp 11, causing the clamp 11 to twist and deform. This twisting and deformation of the clamp 11 is detrimental to its long-term use. By providing a support part 111 on the clamp 11, when the hydraulic cylinder retracts, the support part 111 provides a supporting force. The torque generated by the supporting force acts on the clamp 11, and its direction is opposite to the torque applied to the locking pin 13 by the hydraulic cylinder. Thus, the two forces cancel each other out, preventing the clamp 11 from twisting during use and improving its service life.

[0026] Specifically, when installing the clamp 11, the support portion 111 on the clamp 11 needs to be placed on the side closer to the hydraulic cylinder. It should also be noted that multiple support portions 111 are provided, that is, support portions 111 are provided on both sides of the clamp 11 on the locking post 13. In this way, regardless of whether it is installed in the forward or reverse direction, there will always be a support portion 111 on one side that can provide support force, thereby providing torque to counteract the torque generated by the hydraulic cylinder.

[0027] Preferably, the clamp 11 is further provided with a reinforcing rib 112, the first end of which is fixedly connected to the snap-fit ​​post 13, and the second end of which is fixedly connected to the support part 111. It can be understood that by providing the reinforcing rib 112, the connection strength between the snap-fit ​​post 13 and the clamp 11, and between the clamp 11 and the support part 111, is improved, preventing deformation of the snap-fit ​​post 13 and the support part 111 during use, and improving the rigidity of the clamp 11, the support part 111, and the snap-fit ​​post 13. Specifically, the clamp 11, the support part 111, and the snap-fit ​​post 13 are all made of metal material, and they can be integrally formed or connected and fixed by welding.

[0028] Preferably, the hoop 11 includes a connecting section 113 and a hinge 114. The connecting section 113 has three sections, and the hinge 114 has two sections. The three sections of the connecting section 113 are hinged sequentially by the two hinges 114. Two locking pins 13 are respectively connected to the connecting section 113 at the beginning and end. The two ends of the latch 12 are respectively connected to the connecting section 113 at the beginning and end.

[0029] It should be noted that when the clamp 11 is a single, continuous strip, it is often circular. To tighten the entire clamp 11 onto the pipe, it needs to be pried open from the locking buckle 12 to easily pass the clamp 11 under the pipe and tighten it. This process is inconvenient, requiring prying open every time. However, by arranging the clamp 11 into three connecting sections 113, which are sequentially hinged by two hinges 114, this structural design allows adjacent connecting sections 113 to rotate around the hinges 114. Therefore, during each installation, the connecting sections 113 in the clamp 11 can rotate and unfold around the hinges 114, facilitating the passage of the clamp 11 under the pipe for installation. This improves installation efficiency and reduces the labor intensity of operators.

[0030] During locking, simply lock the locking buckle 12 to the connecting sections 113 at the beginning and end to tighten the clamp 11 onto the pipe. It is important to note that the hinge 114 is located between the two connecting sections 113, or the hinge 114 protrudes outwards from the two connecting sections 113. This arrangement prevents the hinge 114 from protruding inwards from the clamp 11, as this would cause it to directly abut against the outer wall of the pipe, potentially damaging the pipe's outer surface.

[0031] The connecting joint 113 is made of steel sheet and has a certain elastic deformation capacity, so that when the clamp 11 tightens the pipe, the connecting joint 113 undergoes elastic deformation, so that the connecting joint 113 can better fit the outer surface of the pipe.

[0032] Preferably, the latch 12 includes a fixed base 121, a hook 122, a latch 123, a handle 124, and a locking pin 125. The fixed base 121 is fixedly connected to the connecting section 113 at the tail end; the handle 124 is hinged to the fixed base 121, the locking pin 125 is hinged to the handle 124, and the hook 122 is connected to the locking pin 125; the latch 123 is fixedly connected to the connecting section 113 at the head end, and the end of the hook 122 away from the locking pin 125 is detachably fastened to the latch 123.

[0033] Specifically, the hook 122 is arranged in a U-shape, with threads on both arms of the U-shape. Through holes are provided at both ends of the locking pin 125. Both U-shaped arms of the hook 122 pass through these through holes and are threadedly connected to adjusting nuts. By rotating the adjusting nuts, the length of the hook 122 extending towards the locking tongue 123 can be adjusted, thereby adjusting the locking position of the latch 12 so that the latch 12 can fully lock the band 11. During locking, the hook 122 is first engaged with the locking tongue 123. Then, the locking handle 124 is driven to rotate around the hinge point on the fixed base 121, causing the hook 122 to rotate and engage with the locking tongue 123, thus achieving locking. It should be noted that the actual locking is achieved by the locking handle 124 driving the hook 122 to rotate, causing the hinge point on the locking handle 124 and the hook 122 to pass the dead engagement point, preventing the locking handle 124 from rotating in the opposite direction, thereby achieving locking.

[0034] In some other embodiments of this application, the two ends of the hook 122 are fixedly connected to the locking pin 125, and locking is achieved by the end of the hook 122 away from the lock handle 124 engaging with the lock tongue 123.

[0035] Preferably, the first end of the snap-fit ​​post 13 is vertically fixed to the outer surface of the clamp 11, and the second end of the snap-fit ​​post 13 is arranged to be cantilevered outward; a snap-fit ​​surface 131 is provided on the outer surface of the snap-fit ​​post 13.

[0036] The snap-fit ​​surface 131 consists of two flat surfaces. Of course, in some other embodiments, the snap-fit ​​surface 131 can also be other surfaces that facilitate snap-fit. Snap-fit ​​grooves are provided at both ends of the hydraulic cylinder. When the hydraulic cylinder snaps into the snap-fit ​​post 13, the snap-fit ​​groove on the hydraulic cylinder engages with the snap-fit ​​surface 131 on the snap-fit ​​post 13. When the hydraulic cylinder rises or retracts, it pushes the snap-fit ​​post 13 to move, thereby pushing the corresponding pipeline to move, thus realizing the installation and disassembly of the pipeline.

[0037] Preferably, a stop cover 132 is provided at the second end of the snap-fit ​​post 13. The stop cover 132 is fixedly connected to the second end of the snap-fit ​​post 13, and a stop step is formed between the stop cover 132 and the snap-fit ​​surface 131.

[0038] In this embodiment, the stop cover 132 and the snap-fit ​​post 13 are integrally formed and arranged. The stop cover 132 prevents the hydraulic cylinder from slipping off the snap-fit ​​post 13 during operation and causing danger. Of course, in some other embodiments, the stop cover 132 can also be designed to be detachably connected to the snap-fit ​​post 13. For example, by providing a stud on the stop cover 132 and a threaded hole on the snap-fit ​​post 13, the stop cover 132 can be fixedly connected to the snap-fit ​​post 13 by threading the stud into the threaded hole.

[0039] Preferably, the system further includes a flexible protective layer 14, which is fixedly connected to the inner side of the clamp 11. Specifically, the flexible protective layer 14 is divided into three sections, each corresponding to one of the three connecting sections 113. The flexible layer is bonded to the inner surface of the connecting section 113 with adhesive. The flexible protective layer 14 contacts the pipe, preventing the connecting section 113 from damaging the outer surface of the pipe.

[0040] Preferably, the flexible protective layer 14 is made of rubber. Of course, in some other embodiments of this application, it can also be made of flexible materials such as silicone, polyurethane, and felt. Rubber is a soft material. When the clamp 11 tightens the pipe, the soft rubber protects the pipe and prevents the metal clamp 11 from scratching the protective layer on the pipe surface, thus protecting the pipe.

[0041] The above description is merely a preferred embodiment of this utility model and is not intended to limit the utility model. Various modifications and variations can be made to this utility model by those skilled in the art. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of this utility model should be included within the protection scope of this utility model.
