Description

Technical Field

[0001] The utility model relates to the technical field of hollow rivets, and specifically relates to a hollow rivet fastener. Background Art

[0002] A hollow rivet fastener is a specially designed fastening device. With its unique structure and excellent performance, it provides an effective solution for connecting various materials. Hollow rivets are usually made of high-strength metal materials and have the characteristics of being strong and durable. Their outer shape is cylindrical, and the middle is a hollow structure. This design enables the rivet to be deformed by a specific tool during installation, thus achieving a firm connection. When in use, the hollow rivet can tightly connect different thicknesses of plates, metal sheets or other materials together. Its installation process is relatively simple and fast. By applying pressure or impact force, one end of the rivet is deformed and expanded, thereby forming a firm clamping force on both sides of the material.

[0003] After retrieval, the Chinese patent with the publication number of CN214837654U discloses a hollow rivet tight. This patent records that by using a connecting rod, the rivet plate and the rivet sleeve can be connected and fixed to ensure the normal use of the rivet. At the same time, when disassembly is required, by knocking on the connecting plate through the connection hole, the connecting plate drives the connecting rod to separate from the connection groove, thereby realizing the separation of the rivet plate and the rivet sleeve, making the disassembly more rapid and not requiring a cutting tool for cutting, which is very convenient and fast during disassembly.

[0004] In this scheme, by knocking on the connecting plate to separate the rivet plate from the rivet sleeve, due to different knocking forces, the situation of being unable to separate often occurs, thus getting stuck inside the workpiece. At this time, it can only be disassembled by cutting the workpiece, which is time-consuming and laborious, resulting in a significant reduction in work efficiency. To solve this technical problem, the utility model proposes a hollow rivet fastener. Content of the Utility Model

[0005] (1) Technical Problem to be Solved

[0006] In this scheme, by knocking on the connecting plate to separate the rivet plate from the rivet sleeve, due to different knocking forces, the situation of being unable to separate often occurs, thus getting stuck inside the workpiece. At this time, it can only be disassembled by cutting the workpiece, which is time-consuming and laborious, resulting in a significant reduction in work efficiency. To solve this technical problem, the utility model proposes a hollow rivet fastener.

[0007] (2) Technical Solution

[0008] To achieve the above object, the utility model is realized by the following technical solutions: A hollow rivet fastener includes a rivet body. A threaded rod is rotatably connected inside the rivet body. A connecting sleeve rod is threadedly connected to the outer side wall of the threaded rod. At the same time, a pair of connecting blocks are fixedly connected to the bottom end of the connecting sleeve rod. A rotating column is rotatably connected inside each connecting block. A rotating plate is fixedly connected to the outer side wall of each rotating column. A chute is opened on the inner side wall of each rotating plate. A fixed block is fixedly connected above the inside of the rivet body. An outer cylinder is fixedly connected to the inner side wall of the fixed block. A pair of springs are fixedly connected to the outer side wall of the outer cylinder. The other end of each spring is fixedly connected to a sliding column. At the same time, inner holes are opened on both sides of the rivet body. The rotating plate is slidably connected in the inner hole.

[0009] Preferably, the connecting sleeve rod is slidably connected in the outer cylinder. The two rotating plates are centrosymmetric through the connecting sleeve rod.

[0010] Preferably, each sliding column corresponds to each chute, and the sliding column is slidably connected in the sliding column.

[0011] Preferably, a top cover is fixedly connected to the top of the rivet body. The threaded rod passes through the top cover and extends into the rivet body, and a turning handle is fixedly connected to the top end of the threaded rod.

[0012] Preferably, a positioning block is fixedly connected to the bottom wall inside the rivet body, and the bottom end of the threaded rod is rotatably connected in the positioning block.

[0013] Preferably, the two chutes are rotatably connected to the outside of the connecting sleeve rod through the rotating columns.

[0014] (III) Beneficial effects

[0015] The utility model provides a hollow rivet fastener. It has the following beneficial effects:

[0016] (1) By turning the handle above the top cover of the rivet body, the rotation of the handle drives the threaded rod to rotate. Since the bottom end of the threaded rod is limited within the positioning block, it can ensure that the threaded rod rotates coaxially. When the threaded rod rotates, it drives the connecting sleeve rod to move up and down. When the connecting sleeve rod moves downward, it drives the rotating plates on the rotating columns on both sides of the connecting block to move. When the rotating plates move to the bottom of the inner hole of the outer cylinder, they are squeezed by the bottom wall of the inner hole and rotate inward. At this time, the springs on the outer wall of the outer cylinder are squeezed, and the sliding columns on the springs are limited within the sliding grooves, ensuring the smoothness of the whole process and preventing jamming. When the threaded rod is rotated in the reverse direction, the connecting sleeve rod moves upward. When the connecting sleeve rod moves to the position of the inner hole, the resilience of the spring will bounce the rotating plates outward, making the rotating plates in an unfolded state. This cooperation mode solves the problems of insufficient stability and difficult disassembly of the existing rivet device during use, making the rivet more stable during use and more convenient to disassemble, greatly improving the work efficiency.

Detailed Description of the Preferred Embodiments

[0022] Next, the technical solutions in the embodiments of the present utility model will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present utility model.

[0023] Please refer to Figures 1-4 , the present utility model provides a technical solution:

[0024] Embodiment 1: A hollow rivet fastener, including a rivet body 1, a threaded rod 4 is rotatably connected inside the rivet body 1, a connecting sleeve rod 6 is threadedly connected to the outer wall of the threaded rod 4, and at the same time, a pair of connecting blocks 7 are fixedly connected to the bottom end of the connecting sleeve rod 6. A rotating column 8 is rotatably connected inside each connecting block 7. A rotating plate 9 is fixedly connected to the outer wall of each rotating column 8. A sliding groove 11 is provided on the inner wall of each rotating plate 9. A fixed block 15 is fixedly connected above the inner part of the rivet body 1, and an outer cylinder 5 is fixedly connected to the inner wall of the fixed block 15. A pair of springs 13 are fixedly connected to the outer wall of the outer cylinder 5. The other end of each spring 13 is fixedly connected to a sliding column 14. At the same time, inner holes 10 are provided on both sides of the rivet body 1. The rotating plate 9 is slidably connected inside the inner hole 10. The connecting sleeve rod 6 is slidably connected inside the outer cylinder 5. The two rotating plates 9 are centrosymmetric through the connecting sleeve rod 6. Each sliding column 14 corresponds to each sliding groove 11, and the sliding column 14 is slidably connected inside the sliding column 14. A top cover 2 is fixedly connected to the top of the rivet body 1. The threaded rod 4 passes through the top cover 2 and extends into the rivet body 1, and a turning handle 3 is fixedly connected to the top end of the threaded rod 4. A positioning block 12 is fixedly connected to the bottom wall inside the rivet body 1, and the bottom end of the threaded rod 4 is rotatably connected inside the positioning block 12. The two sliding grooves 11 are rotatably connected to the outside of the connecting sleeve rod 6 through the rotating columns 8.

[0025] By rotating the turning handle 3 at the top of the top cover 2, when the turning handle 3 rotates, it will drive the threaded rod 4 to rotate. Since the bottom end of the threaded rod 4 is limited inside the positioning block 12, it can ensure that the threaded rod 4 rotates coaxially. When the threaded rod 4 rotates, it will drive the connecting sleeve rod 6 to move up and down. During the downward movement of the connecting sleeve rod 6, it will drive the rotating plates 9 on the two rotating columns 8 on both sides of the connecting block 7 to move downward together. When the rotating plate 9 moves to the bottom wall surface of the inner hole 10, it will be squeezed by the wall surface and turn inward. When the rotating plate 9 turns inward, it will squeeze the spring 13 on the outer wall of the outer cylinder 5, and the sliding column 14 on the spring 13 is limited inside the sliding groove 11, so that it can ensure that there will be no jamming situation during the whole process. When the threaded rod 4 is rotated in the reverse direction, the connecting sleeve rod 6 will move upward. After the connecting sleeve rod 6 moves to the position of the inner hole 10, through the rebounding effect of the spring 13, it will bounce the rotating plate 9 outward, so that the rotating plate 9 is in an unfolded state. Through the close cooperation between the above-mentioned various components, the rivet body 1 is more stable during use, and it is also more convenient to disassemble when needed, greatly improving the work efficiency and bringing convenience to the use and maintenance of the rivet.

[0026] Working principle: When the staff uses the rivet body 1, by rotating the handle 3 at the top of the top cover 2, the rotation of the handle 3 drives the threaded rod 4 to rotate. The bottom end of the threaded rod 4 is limited within the positioning block 12, so that the threaded rod 4 rotates coaxially. When the threaded rod 4 rotates, it drives the connecting sleeve rod 6 to move up and down. When the connecting sleeve rod 6 moves downward, it drives the rotating plates 9 on the rotating columns 8 on both sides of the connecting block 7 to move downward. When the rotating plate 9 moves to the bottom wall of the inner hole 10, it squeezes the rotating plate 9 to rotate inward. When the rotating plate 9 rotates inward, it squeezes the spring 13 on the outer wall of the outer cylinder 5, and the sliding column 14 on the spring 13 is limited within the sliding groove 11, and there will be no jamming situation. When the threaded rod 4 is rotated in the reverse direction, the connecting sleeve rod 6 moves upward. After the connecting sleeve rod 6 moves to the position of the inner hole 10, the elasticity of the spring 13 will push the rotating plate 9 outward, so that the rotating plate 9 is in an unfolded state. Through their cooperation, the rivet body 1 is more stable during use, and the disassembly is also relatively convenient, improving the work efficiency.
