Description

Technical Field

[0001] This utility model relates to the field of netting crossing technology, specifically a docking device for netting crossing. Background Technology

[0002] The core function of the netting crossing frame docking device is to achieve precise and stable connections between multiple sets of fixed poles, ensuring the safety and efficiency of netting operations. By quickly splicing different segments or units through standardized interfaces, the entire crossing frame forms a continuous and unified support framework, ensuring that the netting maintains flatness and tension when covering obstacles such as railways, highways, and power lines, avoiding risks such as sagging or displacement due to loose connections.

[0003] Currently, some cross-bracing structures use a single bolt to connect two sets of support rods. This connection method results in a single stress point, making it difficult to effectively distribute external forces and leading to poor stability. Furthermore, during construction, the support rods are connected at an angle to form a triangular structure. If only wire is used for fixing, the wire's strength is limited and it is easily loosened by vibration and external pulling forces, further reducing the stability of the structure. To address these issues, a connection device for a netted cross-bracing structure is proposed. Utility Model Content

Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Please see Figures 1-4 In this embodiment, a docking device for a netting crossing frame includes several sets of node rods 11 and receiving rods 12 inserted into the node rods 11. The node rods 11 are provided with positioning components for fixing the receiving rods 12.

[0024] The positioning assembly includes two sets of limiting seats 16 and hinge blocks 17. The two sets of limiting seats 16 are respectively disposed on both sides of the insertion point of the node rod 11 and the receiving rod 12. The hinge blocks 17 are fixed to one side of the limiting seats 16, and the two sets of hinge blocks 17 are rotatably connected. An insertion block 22 is fixedly connected to the outer surface of the receiving rod 12. An insertion groove 18 for engaging the insertion block 22 is provided on the adjacent side of both sets of limiting seats 16. The nodes 11 and 12 are connected by a connector. The receiving rod 12 is inserted into the node rod 11, and then two sets of limiting seats 16 are snapped onto the node rod 11 and the receiving rod 12, so that the limiting seats 16 are snapped into the groove 15, and the node rod 11 and the snap block 14 are snapped into the limiting groove 19. The plug block 22 is snapped into the plug groove 18. The connector fixes the two sets of limiting seats 16, thus completing the connection between the node rod 11 and the receiving rod 12, avoiding a single connection and improving stability.

[0025] Four sets of node rods 11 are fixedly connected to the outer surface of the end of one set of node rods 11. The four sets of node rods 11 are evenly arranged in the circumferential direction of the central axis of one set of node rods 11. A fixing rod 23 is fixedly connected to the end of one set of node rods 11. Adjacent sets of fixing rods 23 are connected by an adjustment assembly.

[0026] The adjustment assembly includes a positioning disk 24 and several sets of positioning holes 25. The positioning disk 24 is fixedly connected to the end of the fixing rod 23 away from the node rod 11. Several sets of positioning holes 25 are formed on the positioning disk 24 and are evenly arranged around the central axis of the positioning disk 24. A set of positioning bolts 26 are inserted into two sets of positioning holes 25. A positioning ring 27 is threaded onto the positioning bolt 26. One side of the positioning ring 27 overlaps with one side of a set of positioning disks 24. The rotation angle of the other set of positioning disks 24 is adjusted according to the required tilt angle. After the angle is determined, the two sets of positioning disks 24 are brought together, and then the positioning bolts 26 are inserted into the two sets of corresponding positioning holes 25. The positioning rings 27 are then screwed onto the positioning bolts 26 to complete the connection between the two sets of positioning disks 24. This facilitates the tilted connection of the receiving rod 12 to form a triangular structure, avoiding loosening due to vibration or external pulling, and improving stability and practicality.

[0027] The connector includes a socket 21 and a connecting bolt 20. The socket 21 is located at the end of the limiting seat 16 away from the hinge block 17. A set of connecting bolts 20 is threaded between the two sets of sockets 21. A limiting ring is threaded onto the connecting bolt 20. The connecting bolt 20 is screwed into the two sets of sockets 21 for fixation, and then the limiting ring is screwed onto the connecting bolt 20 to connect and fix the two sets of limiting seats 16.

[0028] A slot 13 is provided on one side of the node rod 11, and a locking block 14 is fixedly connected to the receiving rod 12. The locking block 14 is engaged in the slot 13. By setting the slot 13 and the locking block 14, the relative displacement between the receiving rod 12 and the node rod 11 can be initially restricted, which makes it easier for the limiting seat 16 to fix the node rod 11 and the receiving rod 12.

[0029] The outer surface of the node rod 11 is provided with a groove 15, and the limiting seat 16 is engaged in the groove 15. The limiting seat 16 is engaged in the groove 15 to prevent the limiting seat 16 from sliding on the node rod 11 and to limit the position of the limiting seat 16.

[0030] The two sets of limiting seats 16 are provided with anti-slip threads on the side near the node rod 11 and the receiving rod 12. By providing anti-slip threads, the friction between the limiting seat 16 and the node rod 11 and the receiving rod 12 can be increased, further preventing the limiting seat 16 from loosening.

[0031] The working principle of this utility model is as follows: During installation, the receiving rod 12 is inserted into the node rod 11, so that the locking block 14 is locked into the locking groove 13. Then, two sets of limiting seats 16 are locked onto the node rod 11 and the receiving rod 12, so that the limiting seats 16 are locked into the groove 15, and the locking point of the node rod 11 and the locking block 14 is locked into the limiting groove 19. The insertion block 22 is locked into the insertion groove 18. Finally, the connecting bolt 20 is screwed into the two sets of insertion holes 21 for fixation, thus completing the connection of the node rod 11 and the receiving rod 12, avoiding single To improve stability, the rotation angle of the other set of positioning discs 24 is adjusted according to the required installation tilt angle. After the adjustment is completed, the two sets of positioning discs 24 are placed together, and then the positioning bolts 26 are inserted into the two corresponding positioning holes 25. The positioning rings 27 are then screwed onto the positioning bolts 26 to complete the connection between the two sets of positioning discs 24. This facilitates the tilted connection of the receiving rod 12 to form a triangular structure, preventing loosening due to vibration or external pulling, thus improving stability and practicality.
