[0031] Please see Figure 1-4 This utility model provides a technical solution: an anti-slip connecting fastener, including an upper buckle 1, a lower buckle 4 and two fixing screws 7;

[0032] Both the upper buckle 1 and the lower buckle 4 are equipped with reinforcing rib assemblies;

[0033] The reinforcing rib assembly includes two mounting plates 11 and two movable seats 13. One end of the outer wall of the upper retaining ring 1 and the lower retaining ring 4 is provided with a movable seat groove 12. The outer walls of the two movable seats 13 are slidably connected to the interior of the corresponding movable seat groove 12. One end of the outer wall of the two mounting plates 11 is fixedly connected to one end of the outer wall of the corresponding movable seat 13. The outer walls of the two side protrusions of the two movable seats 13 are slidably connected to the interior of the two side tapered grooves of the corresponding movable seat groove 12. Multiple reinforcing ribs 10 are installed on the outer walls of both mounting plates 11, and two reinforcing ribs 10 are fixedly connected to the outer walls of both movable seats 13. Each of the four fixed brackets 15 has two fixing bolt slots 17 on the outer wall of one end of the upper buckle 1 and the lower buckle 4. Each of the four fixed brackets 15 has a fixing bolt 5 threadedly connected to the outer wall of one end. The ends of the four fixing bolts 5 near the fixing bolt slots 17 are threaded to the outside of the fixed bracket 15 and are respectively threaded to the inside of the corresponding fixing bolt slots 17. The inner walls of the two movable seats 13 are arc-shaped. The inner walls of the two mounting plates 11 are respectively in contact with the outer walls of the upper buckle 1 and the lower buckle 4. The inner walls of the two movable seats 13 are respectively in contact with the inner walls of the corresponding movable seat slots 12.

[0034] The upper retaining ring 1 and the lower retaining ring 4 are both provided with internal threads 2 on their inner walls. The outer wall of the upper retaining ring 1 is fixedly connected to two second fixing plates 9. The outer wall of each of the two second fixing plates 9 is fixedly connected to a positioning post 8 on one side. The outer wall of the lower retaining ring 4 is fixedly connected to two first fixing plates 3. The upper surface of each of the two first fixing plates 3 is provided with two positioning post grooves 16. The outer wall of each of the two positioning posts 8 is slidably connected to the interior of the corresponding positioning post groove 16. The outer wall of each of the two fixing screws 7 is fixedly connected to a bolt head 14 on one end. The two second fixing plates 9 are respectively corresponding to the corresponding first fixing plates 3. The outer wall of the lower end of each of the two fixing screws 7 is slidably connected to the interior of the groove on the upper surface of the corresponding second fixing plate 9. The outer wall of the two fixing screws 7 away from the second fixing plate 9 slides to the interior of the groove on the upper surface of the corresponding first fixing plate 3. The outer wall of the two fixing screws 7 near the first fixing plate 3 is threadedly connected to a fastening nut 6. The outer wall of each of the two fastening nuts 6 is in contact with the outer wall of the corresponding first fixing plate 3 on one side.

[0035] Furthermore, when using this device, it is started by connecting to an external power source. First, the internal threads 2 on both the upper retaining ring 1 and the lower retaining ring 4 are aligned with the outer wall of the workpiece, while the four positioning pins 8 are inserted into the positioning pin grooves 16. Then, the fixing screw 7 is inserted into the groove of the second fixing plate 9 on the upper retaining ring 1 and extends to the outside of the first fixing plate 3 on the lower retaining ring 4. Next, the fastening nut 6 is turned to rotate and cause the washer to contact one side of the outer wall of the first fixing plate 3. This controls the distance between the upper retaining ring 1 and the lower retaining ring 4. At the same time, the internal threads 2 on the upper retaining ring 1 and the lower retaining ring 4 contact the outer wall of the workpiece, thus improving the connection stability of the fastener. This completes the installation of the fastener. Next, the inner wall of the mounting plate 11 is attached to the outer wall of the upper buckle 1 and the lower buckle 4. In this way, the reinforcing rib 10 on the mounting plate 11 protects the upper buckle 1 and the lower buckle 4, effectively increasing the section modulus of the fastener, thereby improving its tensile strength. At the same time, it helps to reduce the deformation of the fastener under stress and maintain the stability of the connection. Then, when it is necessary to remove the reinforcing rib 10, the fixing bolt 5 is turned to rotate so that the outer wall of its other end is disengaged from the inside of the fixing bolt groove 17. Then, the movable seat 13 is pulled to remove the movable seat 13 and the mounting plate 11 from the upper buckle 1 and the lower buckle 4. This completes the removal of the reinforcing rib 10 from the upper buckle 1 and the lower buckle 4.

[0036] The inner wall of the mounting plate 11 in the reinforcing rib assembly is attached to the outer walls of the upper buckle 1 and the lower buckle 4. In this way, the reinforcing rib 10 on the mounting plate 11 protects the upper buckle 1 and the lower buckle 4, effectively increasing the section modulus of the fastener and thus improving its tensile strength. At the same time, it helps to reduce the deformation of the fastener under stress and maintain the stability of the connection. By turning the fixing bolt 5, the outer wall of its other end is disengaged from the inside of the fixing bolt groove 17. Then, by pulling the movable seat 13, the movable seat 13 and the mounting plate 11 can be removed from the upper buckle 1 and the lower buckle 4. This completes the removal of the reinforcing rib 10 from the upper buckle 1 and the lower buckle 4. This facilitates the disassembly of the reinforcing rib 10, effectively improves the maintenance and repair efficiency of the reinforcing rib 10, and also improves the work efficiency of the staff.

In this way, the reinforcing rib 10, mounting plate 11 and movable seat 13 are installed on the upper buckle 1 and the lower buckle 4 through the movable seat groove 12. This helps to reduce the deformation of the fastener under force and maintain the stability of the connection.

[0039] Second fixing plate 9, positioning post 8, first fixing plate 3 and fixing screw 7: The second fixing plate 9 corresponds to the position of the first fixing plate 3. Then, the outer wall of the positioning post 8 on the second fixing plate 9 is slidably connected to the inside of the positioning post groove 16 opened on the first fixing plate 3. At the same time, the second fixing plate 9 and the first fixing plate 3 are improved by the cooperation of fixing screw 7 and fastening nut 6.

[0040] Fixed bracket 15 and fixing bolt 5: The fixed bracket 15 is installed on the movable seat 13. Then, the fixed bracket 15 and fixing bolt 5 are used to install the movable seat 13 on the upper buckle 1 and the lower buckle 4. In this way, the fixed bracket 15 and fixing bolt 5 are used to install the movable seat 13, the mounting plate 11 and the reinforcing rib 10 on the upper buckle 1 and the lower buckle 4, which effectively improves the stability of the connection between the reinforcing rib 10 and the upper buckle 1 and the lower buckle 4.
