Description

Technical Field

[0001] The present invention relates to the technical field of pipeline bolt fasteners, and specifically to a positioning buckle push-rotation type high-strength pipeline bolt fastener. Background Art

[0002] The positioning buckle push-rotation type high-strength pipeline bolt fastener is a fastening device used for connecting and fixing pipeline components in a pipeline system. It mainly consists of a high-strength bolt and a buckle structure. Through the push-rotation design, it can achieve rapid and firm pipeline connection. The core feature of this fastener design is the combination of the buckle and the push-rotation mechanism, which enables rapid locking and fastening during the installation process, thereby improving the overall installation efficiency and fastening force.

[0003] The prior art is not convenient for single-sided fastening. In some environments with narrow spaces or limited operating positions, the inability to perform single-sided fastening means that sufficient operating space needs to be reserved on both sides of the pipeline to install and operate tools for fastening the bolts. For some compact equipment, dense pipeline layouts, or difficult-to-reach positions, this may increase the installation difficulty and even make it impossible to complete the installation due to insufficient space.

The inner part of the first circular block is provided with a limiting hole. The outer wall of the spline shaft is connected to the inner wall of the limiting hole. The outer wall of the first circular block is provided with a sliding groove. The outer wall of the spline shaft is connected to a folding gasket. The outer wall of the folding gasket is slidably connected to the inner wall of the sliding groove. The outer wall of the folding gasket is connected to the outer wall of the first fixing part. One end of the circular ring is provided with a rotating assembly, and the outer wall of the threaded section of the fastening bolt is provided with a fastening assembly.

[0007] Preferably, the rotating assembly includes a threaded column, one end of the threaded column is fixedly connected to one end of the ring, the outer wall of the threaded column is threadedly connected to a second gear, the outer wall of the second gear is meshed with the outer wall of the toothed ring, the outer wall of the threaded column is connected to the inner wall of the limiting hole, and the outer wall of the threaded column is connected to the inside of the first round block.

[0008] Preferably, the fastening assembly includes a fastening nut and a fastening gasket, the outer wall of the fastening nut is threadedly connected to the outer wall of the threaded section of the fastening bolt, and the outer wall of the fastening gasket is slidably connected to the outer wall of the threaded section of the fastening bolt.

[0009] Preferably, one end of the fastening bolt is fixedly connected with a clamping block, a positioning groove is formed at the other end of the ring, and the outer wall of the clamping block is slidably connected to the inner wall of the positioning groove.

[0010] Preferably, a limiting groove is formed in the outer wall of the second fixing member, a limiting block is fixedly connected to the outer wall of the first round block, and the outer wall of the limiting block is slidably connected to the inner wall of the limiting groove.

[0011] Preferably, one end of the ring is fitted with one end of the first round block, and one end of the cylindrical section of the fastening bolt close to the threaded section is fitted with the end of the ring away from the spline shaft.

[0012] Preferably, one end of the fastening nut is fitted with one end of the fastening gasket, and the other end of the fastening gasket is fitted with the outer wall of the second fixing member.

[0013] Preferably, the outer diameter of the first round block is the same as the outer diameter of the ring, the inner diameter of the first round block is the same as the outer diameter of the threaded section of the fastening bolt, and the outer diameter of the cylindrical section of the fastening bolt is the same as the outer diameter of the first round block.

[0014] Preferably, the inner diameter of the fastening gasket is the same as the outer diameter of the threaded section of the fastening bolt, and the outer diameter of the fastening gasket is larger than the outer diameter of the first round block.

[0015] Preferably, the inner diameter of the first round block is the same as the inner diameter of the ring.

[0016] Working principle: During use, first assemble the first round block and the ring onto the outer wall of the threaded section of the fastening bolt. Then, drive the first round block and the ring through the inner wall of the mounting holes opened on the outer walls of the first fixing part and the second fixing part by the fastening bolt. When the first round block passes through the mounting holes opened on the outer walls of the first fixing part and the second fixing part, the first round block will drive the limiting block to slide into the inner wall of the limiting groove opened on the outer wall of the second fixing part. Then, keep the position of the first round block unchanged and pull the threaded section of the fastening bolt to make the cylindrical section of the fastening bolt move and fit with the end of the ring away from the spline shaft. During this process, the fastening bolt will drive the clamping block to slide into the inner wall of the positioning groove. During the pulling process, the ring will be forced to move, and then the threaded column will move and slide on the inner wall of the first round block and the limiting hole, thereby causing the second gear to rotate. When the second gear rotates, it will cause the toothed ring to rotate on the inner wall of the first round block. When the toothed ring rotates, it will drive the first gear to rotate, and then cause the spline shaft to rotate during the moving process. When the spline shaft rotates, it will drive the folding gasket to slide and unfold on the inner wall of the sliding groove and slide on the outer wall of the first fixing part. At this time, install the fastening gasket and the fastening nut in sequence, and fasten the fastening bolt with the fastening nut to complete the unilateral fastening of the first fixing part and the second fixing part, reducing the complexity of the need for simultaneous operation on both sides, improving adaptability, and significantly shortening the installation and maintenance time. It not only saves the cost of manual operation but also speeds up the overall installation progress;

[0017] When fastening the fastening nut, since the limiting block fixedly connected to the outer wall of the first round block slides into the inner wall of the limiting groove opened on the outer wall of the second fixing part, it ensures that the first round block will not rotate. At the same time, the clamping block slides into the inner wall of the positioning groove to ensure that the first fixing part will not rotate during fastening. This can reduce the additional operation of fixing the threaded section of the fastening bolt, reduce manual operation, improve installation efficiency, and reduce the risk of thread wear.

[0018] The present invention provides a positioning buckle push-rotating high-strength pipeline bolt fastener. It has the following beneficial effects:

[0019] 1. In the present invention, when the spline shaft rotates, it will drive the folding gasket to slide and unfold on the inner wall of the sliding groove, and then fasten the fastening bolt with the fastening nut to complete the unilateral fastening of the first fixing part and the second fixing part, reducing the complexity of the need for simultaneous operation on both sides, improving adaptability, significantly shortening the installation and maintenance time, saving the cost of manual operation, and speeding up the overall installation progress.

[0020] 2. In the present invention, the limiting block fixedly connected to the outer wall of the first round block slides into the inner wall of the limiting groove opened on the outer wall of the second fixing member, ensuring that the first round block does not rotate. At the same time, the clamping block slides into the inner wall of the positioning groove to ensure that the first fixing member does not rotate during fastening. This can reduce the operation of additionally fixing the threaded section of the fastening bolt, reduce manual operation, improve the installation efficiency, and reduce the risk of thread wear.

[0021] 3. In the present invention, by adopting assembled components, the operation is simple, the positioning and installation are fast, and it can adapt to various working conditions. BRIEF DESCRIPTION OF THE DRAWINGS

[0029] Next, the technical solutions of the present invention will be clearly and completely described in conjunction with the drawings of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0030] Please refer to the attached Figure 1 -attached Figure 5, the embodiment of the present invention provides a positioning buckle push-rotating high-strength pipeline bolt fastener, including a first fixing member 1, a fastening bolt 3 and a ring 5. The outer wall of the first fixing member 1 is attached to a second fixing member 2. The outer wall of the cylindrical section of the fastening bolt 3 is slidably connected to the inner wall of the mounting holes opened on the outer walls of the first fixing member 1 and the second fixing member 2. The outer wall of the threaded section of the first fixing member 1 is slidably connected to a first circular block 4. The inner wall of the first circular block 4 is rotatably connected to a toothed ring 6. The toothed end of the toothed ring 6 is meshed and connected to a first gear 7. The inner wall of the first gear 7 is connected to a spline shaft 8. The outer wall of the spline shaft 8 is connected inside the first circular block 4. The outer wall of the spline shaft 8 is fixedly connected to a second circular block 9. A rotating groove 12 is opened inside the ring 5. The outer wall of the second circular block 9 is rotatably connected to the inner wall of the rotating groove 12. A limiting hole 21 is opened inside the first circular block 4. The outer wall of the spline shaft 8 is connected to the inner wall of the limiting hole 21. A sliding groove 11 is opened on the outer wall of the first circular block 4. The outer wall of the spline shaft 8 is connected to a folding gasket 10. The outer wall of the folding gasket 10 is slidably connected to the inner wall of the sliding groove 11. The outer wall of the folding gasket 10 is connected to the outer wall of the first fixing member 1. One end of the ring 5 is provided with a rotating assembly, and the outer wall of the threaded section of the fastening bolt 3 is provided with a fastening assembly; the rotating assembly includes a threaded column 14. One end of the threaded column 14 is fixedly connected to one end of the ring 5. The outer wall of the threaded column 14 is threadedly connected to a second gear 13. The outer wall of the second gear 13 is meshed and connected to the outer wall of the toothed ring 6. The outer wall of the threaded column 14 is connected to the inner wall of the limiting hole 21. The outer wall of the threaded column 14 is connected inside the first circular block 4; the fastening assembly includes a fastening nut 15 and a fastening gasket 16. The outer wall of the fastening nut 15 is threadedly connected to the outer wall of the threaded section of the fastening bolt 3. The outer wall of the fastening gasket 16 is slidably connected to the outer wall of the threaded section of the fastening bolt 3;

[0031] Specifically, when fixing the pipeline, place the pipeline to be fixed on the inner wall between the first fixing member 1 and the second fixing member 2, then fit the first fixing member 1 and the second fixing member 2 together, and then the fastening operation can be carried out. Among them, the movement of the threaded column 14 can rotate the second gear 13, thereby enabling the toothed ring 6 to rotate on the inner wall of the first round block 4. When the first round block 4 rotates, it will drive the first gear 7 meshed with it to rotate. When the first gear 7 rotates, it will drive the spline shaft 8 to rotate. The spline shaft 8 rotates during the movement and drives the second round block 9 to rotate on the inner wall of the rotating groove 12 opened at one end of the ring 5 close to the spline shaft 8. The rotating groove 12 provides space for the rotation of each individual second round block 9. The spline shaft 8 can slide inside the folding gasket 10 during rotation and drive the folding gasket 10 to rotate and unfold. The limiting hole 21 opened inside the first round block 4 provides space for the movement of the threaded column 14 and the spline shaft 8. When disassembling the fastening bolt 3, a tool can also be used to push the threaded column 14 to move reversely from the inner wall of the limiting hole 21, thereby prompting the folding gasket 10 to retract into the inner wall of the sliding groove 11. At this time, the disassembly of the fastening bolt 3 can be completed, which is convenient for maintaining the pipeline.

[0032] Please refer to the attached Figure 3 - attached Figure 6 One end of the fastening bolt 3 is fixedly connected with a clamping block 18, and a positioning groove 17 is opened at the other end of the ring 5. The outer wall of the clamping block 18 is slidably connected to the inner wall of the positioning groove 17; a limiting groove 19 is opened on the outer wall of the second fixing member 2, and a limiting block 20 is fixedly connected to the outer wall of the first round block 4. The outer wall of the limiting block 20 is slidably connected to the inner wall of the limiting groove 19;

[0033] Specifically, during installation, when the fastening bolt 3 drives the first round block 4 to pass through the inner wall of the installation hole opened on the outer walls of the first fixing member 1 and the second fixing member 2, the limiting block 20 is driven by the first round block 4 to slide into the inner wall of the limiting groove 19 opened on the outer wall of the second fixing member 2. Then, keep the position of the first round block 4 unchanged, which can ensure that the first round block 4 will not rotate during the assembly process. During the process of pulling the fastening bolt 3, the fastening bolt 3 will drive the clamping block 18 to slide into the inner wall of the positioning groove 17 opened at one end of the ring 5 away from the spline shaft 8, thereby ensuring that the fastening bolt 3 will not rotate during the assembly process.

[0034] Please refer to the attached Figure 1 - attached Figure 2 One end of the ring 5 is in contact with one end of the first round block 4, and one end of the cylindrical section of the fastening bolt 3 close to the threaded section is in contact with one end of the ring 5 away from the spline shaft 8; one end of the fastening nut 15 is in contact with one end of the fastening gasket 16, and the other end of the fastening gasket 16 is in contact with the outer wall of the second fixing member 2;

[0035] Specifically, when the assembly is completed, one end of the ring 5 will be in contact with one end of the first round block 4, one end of the cylindrical section of the fastening bolt 3 near the threaded section will be in contact with the end of the ring 5 away from the spline shaft 8, one end of the fastening nut 15 will be in contact with one end of the fastening gasket 16, and the other end of the fastening gasket 16 will be in contact with the outer wall of the second fixing member 2, which can enhance the connection strength and improve the fixing effect.

[0036] Please refer to the appendix Figure 1 - appendix Figure 2 , the outer diameter of the first round block 4 is the same as the outer diameter of the ring 5, the inner diameter of the first round block 4 is the same as the outer diameter of the threaded section of the fastening bolt 3, and the outer diameter of the cylindrical section of the fastening bolt 3 is the same as the outer diameter of the first round block 4; the inner diameter of the fastening gasket 16 is the same as the outer diameter of the threaded section of the fastening bolt 3, and the outer diameter of the fastening gasket 16 is larger than the outer diameter of the first round block 4; the inner diameter of the first round block 4 is the same as the inner diameter of the ring 5;

[0037] Specifically, the outer diameter of the first round block 4 is the same as the outer diameter of the ring 5, and at the same time, the outer diameter of the cylindrical section of the fastening bolt 3 is the same as the outer diameter of the first round block 4. The outer diameters of the fastening bolt 3, the first round block 4, and the ring 5 are all the same, so that the fastening bolt 3, the first round block 4, and the ring 5 can pass through the inner wall of the installation holes opened on the outer walls of the first fixing member 1 and the second fixing member 2 during installation. The outer diameter of the fastening gasket 16 is larger than the outer diameter of the first round block 4, and thus larger than the inner diameter of the installation holes opened on the outer walls of the first fixing member 1 and the second fixing member 2, which can improve the fastening stability and enhance the sealing performance during assembly.
