Description

Technical Field

[0001] This utility model relates to the field of riveting equipment technology, and in particular to seamless riveting rivets. Background Technology

[0002] Seamless riveting rivets are a type of rivet. They are mainly used to solve the instability problems that may occur during the riveting process of traditional rivets, such as loose riveting, deformation or breakage. Compared with traditional rivets, they can better adapt to the tolerance changes of rivet hole diameter and rivet shank diameter, avoiding rivet scrap due to dimensional deviations.

[0003] In the seamless riveting process, the rivet is inserted into the hole of the material to be joined using a specialized riveting tool. Pressure is then applied to cause plastic deformation of the riveting portion, resulting in a tight bond with the material. This connection method eliminates the need for welding or threaded connections, thus avoiding the heat-affected zone and residual stress associated with welding, as well as the loosening and leakage problems of threaded connections.

[0004] However, under different temperature environments, the materials will expand and contract. The connection parts fixed by seamless riveting rivets may experience stress concentration due to the expansion and contraction of the materials. The bonding force between the rivet and the plate will gradually weaken, and may even loosen or fall off, thus affecting the stability of the connection. Therefore, seamless riveting rivets are proposed to solve the above problems. Utility Model Content

[0005] To overcome the above shortcomings, this utility model provides a seamless riveting rivet, which aims to improve the problem that in traditional equipment, the material expands and contracts under different temperature conditions, and the bonding force between the rivet and the plate gradually weakens, or even loosens or falls off.

[0006] To achieve the above objectives, the present invention adopts the following technical solution:

[0007] A seamless riveting rivet includes a rivet head, a rivet head fixedly connected to one side of the rivet head, a rivet shank provided on one side of the rivet head, a slot provided inside the rivet shank, a trapezoidal cone fixedly connected to one side of the rivet shank, a fixed cylinder slidably connected to the outer wall of the rivet shank, multiple fixed grooves provided inside the fixed cylinder, multiple square locking blocks provided on the inner wall of the fixed cylinder, the outer walls of each square locking block slidably connected to the inner wall of the fixed groove, a telescopic post fixedly connected to one side of each square locking block, a rubber pad fixedly connected to one side of each telescopic post, a spring provided on the outer wall of each telescopic post, one side of each spring fixedly connected to the outer wall of each square locking block, and the other side of each spring fixedly connected to the outer wall of the rubber pad. A connecting assembly is provided inside the rivet head for installing and disassembling the rivet head.

[0008] As a further description of the above technical solution:

[0009] The connecting component includes an arc-shaped locking block, the outer wall of which is disposed inside the rivet joint, the bottom of which is disposed on the outer wall of the slot, and the outer walls of which are fixedly connected to the inner wall of the fixing slot.

[0010] As a further description of the above technical solution:

[0011] The rivet head has a second fixing groove inside, a protective pad is fixedly connected to one side of the rivet rod, and a connecting plate is fixedly connected to one side of the protective pad;

[0012] As a further description of the above technical solution:

[0013] The outer wall of the connecting plate is disposed inside the fixing groove, and a connecting rod is fixedly connected to one side of the connecting plate. The connecting rod is fixedly connected to the outer wall of the arc-shaped block on one side.

[0014] As a further description of the above technical solution:

[0015] Both sides of the arc-shaped card block are provided with square card blocks two, and a connecting column is fixedly connected to one side of each square card block two. A fixing ring is slidably connected to the outer wall of the connecting column.

[0016] As a further description of the above technical solution:

[0017] Each connecting column is provided with a second spring on its outer wall. One side of the second spring is fixedly connected to the outer wall of the square locking block, and the other side of the second spring is fixedly connected to the outer wall of the fixing ring.

[0018] As a further description of the above technical solution:

[0019] A connecting plate two is fixedly connected to one side of each fixing ring, and the outer wall of the connecting plate two is slidably connected to the inner wall of the fixing groove two.

[0020] As a further description of the above technical solution:

[0021] Each of the two connecting plates has a handle fixedly connected to one side, and the outer wall of the handle is slidably connected to the inner wall of the two fixing grooves.

[0022] This utility model has the following beneficial effects:

[0023] 1. In this utility model, the nail rod slides on the inner wall of the fixed cylinder, and the trapezoidal cone is used to squeeze the square locking block to shrink it. Then, it continues to move until the locking groove moves to the outer wall of the square locking block. The rebound force of the telescopic column is used to push the square locking block to move, thereby achieving the fixing effect of the nail rod. This solves the problem that in traditional equipment, the material expands and contracts under different temperature conditions, and the bonding force between the rivet and the plate gradually weakens, or even loosens or falls off. This enhances the stability of the connection of the equipment.

[0024] 2. In this utility model, the arc-shaped locking block on one side of the nail rod is moved to the outer wall of the connecting rod, and the connecting rod is used to lock and fix the arc-shaped locking block. During disassembly, the two square locking blocks on both sides are pulled apart from the outer wall of the arc-shaped locking block, thereby pulling the arc-shaped locking block out of the rivet joint. This achieves quick installation, disassembly, and replacement of the rivet joint, solving the problem that traditional equipment usually requires recycling and remanufacturing the entire equipment after use due to deformation of the rivet joint, which increases the cost of equipment use and improves the utilization efficiency of the equipment.

[0036] Reference Figure 1 - Figure 2This utility model provides an embodiment of a seamless riveting rivet, comprising a rivet head 1, a rivet head 2 fixedly connected to one side of the rivet head 1, a rivet shank 3 provided on one side of the rivet head 2, a slot 10 formed inside the rivet shank 3, a trapezoidal cone 19 fixedly connected to one side of the rivet shank 3, a fixing cylinder 4 slidably connected to the outer wall of the rivet shank 3, a plurality of fixing grooves 5 formed inside the fixing cylinder 4, a plurality of square locking blocks 9 provided on the inner wall of the fixing cylinder 4, the outer walls of the square locking blocks 9 slidably connected to the inner walls of the fixing grooves 5, and a telescopic post 7 fixedly connected to one side of each square locking block 9. Each side of the telescopic column 7 is fixedly connected to a rubber pad 6. Each side of the telescopic column 7 is provided with a spring 8. One side of each spring 8 is fixedly connected to the outer wall of a square clip 9. The other side of each spring 8 is fixedly connected to the outer wall of the rubber pad 6. The riveting joint 2 is provided with a connecting component. The connecting component is used for the installation and disassembly of the riveting joint 2. The connecting component includes an arc-shaped clip 13. The outer wall of the arc-shaped clip 13 is located inside the riveting joint 2. The bottom of the square clip 9 is located on the outer wall of the slot 10. The outer wall of each rubber pad 6 is fixedly connected to the inner wall of the fixing groove 5.

[0037] Specifically, during the actual use of the equipment, the fixing cylinder 4 is fixed to the inner wall of the connecting hole, and then the nail rod 3 is moved into the interior of the fixing cylinder 4. During this process, the trapezoidal cone 19 will squeeze the square locking block 9. Under the action of this squeezing force, the spring 8 and the telescopic column 7 begin to compress. The telescopic column 7 can effectively limit and guide the compression and extension process of the spring 8 by utilizing its own telescopic characteristics. When the nail rod 3 continues to move, the locking groove 10 on its outer wall gradually moves to the side of the square locking block 9, and the square locking block 9 loses the squeezing force from the trapezoidal cone 19. At this time, the spring 8 uses its stored elastic potential energy to push the square locking block 9 to the inner wall of the locking groove 10, thereby realizing the locking and fixing function of the nail rod 3. This solves the problem that in traditional equipment, the material expands and contracts under different temperature conditions, and the bonding force between the rivet and the plate gradually weakens, or even loosens or falls off. This enhances the stability of the connection of the equipment.

[0038] Reference Figure 3 - Figure 4The rivet joint 2 has a fixing groove 18 inside. A protective pad 22 is fixedly connected to one side of the nail rod 3. A connecting plate 11 is fixedly connected to one side of the protective pad 22. The outer wall of the connecting plate 11 is set inside the fixing groove 18. A connecting rod 12 is fixedly connected to one side of the connecting plate 11. One side of the connecting rod 12 is fixedly connected to the outer wall of the arc-shaped locking block 13. Square locking blocks 14 are set on both sides of the arc-shaped locking block 13. A connecting post 16 is fixedly connected to one side of each square locking block 14. A fixing ring 15 is slidably connected to the outer wall of the connecting post 16. A spring 20 is set on the outer wall of each connecting post 16. One side of the spring 20 is fixedly connected to the outer wall of the square locking block 14. The other side of the spring 20 is fixedly connected to the outer wall of the fixing ring 15. A connecting plate 17 is fixedly connected to one side of each fixing ring 15. The outer wall of the connecting plate 17 is slidably connected to the inner wall of the fixing groove 18. A handle 21 is fixedly connected to one side of each connecting plate 17. The outer wall of the handle 21 is slidably connected to the inner wall of the fixing groove 18.

[0039] Specifically, during the replacement of rivet 2, the operator first pulls the handles 21 on both sides in the opposite direction. This strong pulling force is transmitted through the connecting plate 17 to the surface of the retaining ring 15, causing the retaining ring 15 to move. Simultaneously, the retaining ring 15 moves, and the square locking block 14 moves synchronously via the spring 20. As the retaining ring 15 continues to move, the square locking block 14 gradually moves out from the outer wall of the arc-shaped locking block 13. Once the square locking block 14 has moved out from the outer wall of the arc-shaped locking block 13, the arc-shaped locking block 13 can be smoothly removed from the inside of the rivet 2, thus completing the disassembly of the rivet 2. During the installation of the rivet 2, the operator moves the arc-shaped locking block 13 into the inside of the rivet 2. When the arc-shaped locking block 13 approaches the square locking block 14... The arc-shaped locking block 13 exerts a squeezing effect on the square locking blocks 14 on both sides. While being squeezed, the square locking blocks 14 drive the connecting column 16 to slide inside the fixing ring 15. At the same time, the spring 20 will generate a compression motion. During this process, the connecting column 16 limits the compression of the spring 20. When the plane on one side of the arc-shaped locking block 13 moves to the oblique groove on the outer wall of the square locking block 14, the spring 20 will rebound quickly. Under the action of the rebound force of the spring 20, the square locking block 14 will lock and fix the arc-shaped locking block 13, realizing the quick installation, disassembly and replacement of the rivet joint 2. This solves the problem that after the traditional equipment is used, the entire equipment usually needs to be recycled and remanufactured because the rivet joint 2 is deformed during use, which increases the cost of equipment use and improves the utilization efficiency of the equipment.

[0040] Working principle: During equipment use, the fixing cylinder 4 is fixed to the inner wall of the connecting hole. Then, the nail rod 3 is moved into the interior of the fixing cylinder 4. The trapezoidal cone 19 compresses the square locking block 9, thereby driving the spring 8 and the telescopic column 7 to compress. The telescopic column 7 can limit and guide the spring 8 as needed. When the slot 10 on the outer wall of the nail rod 3 moves to one side of the square locking block 9, the square locking block 9 loses its compressive force. The spring 8 then pushes the square locking block 9 to the inner wall of the slot 10, thus achieving the locking and fixing effect of the nail rod 3. During the replacement of the rivet joint 2, the handles 21 on both sides are pulled in opposite directions. The pulling force is transmitted to the surface of the fixing ring 15 through the connecting plate 17, thereby pushing the fixing ring 15 to move. Simultaneously, the spring 20 will drive the square locking block 14 to move out from the outer wall of the arc-shaped locking block 13, thus allowing the arc-shaped locking block 13 to move smoothly out of the riveting joint 2. During the installation of the riveting joint 2, the arc-shaped locking block 13 is moved into the interior of the riveting joint 2. When the arc-shaped locking block 13 approaches the square locking block 14, it will squeeze the square locking blocks 14 on both sides. While the square locking blocks 14 are squeezing, the connecting post 16 will slide inside the fixing ring 15. At the same time, the spring 20 will generate a compression movement. The connecting post 16 will limit the compression of the spring 20. When one side of the arc-shaped locking block 13 moves to the oblique groove on the outer wall of the square locking block 14, the spring 20 will rebound, thereby driving the square locking block 14 to lock and fix the arc-shaped locking block 13, thus achieving the fixing effect of the riveting joint 2.

[0041] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions and improvements made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
