[0003] In traditional grid structure connection technology, bolt-ball nodes are a common connection method, which realizes the connection of grids through a combination of bolts and balls. However, the existing grid bolt-ball nodes have some disadvantages during the assembly and disassembly process. During the assembly process, the alignment of the bolts and the balls often requires the operator to make multiple adjustments, which is not only time-consuming but also prone to errors. During the assembly or disassembly process, the position adjustment of the bolts is not flexible enough, which limits the convenience of operation. Utility Model Content

[0026] In order to more clearly understand the above-mentioned purpose, features and advantages of the present invention, the present invention is further described below with reference to the accompanying drawings and embodiments. It should be noted that the embodiments of the present application and the features therein can be combined with each other without conflict.

[0027] In the following description, many specific details are set forth to facilitate a full understanding of the present invention. However, the present invention may also be implemented in other ways than those described herein. Therefore, the present invention is not limited to the specific embodiments disclosed in the following specification.

[0028] See also Figure 1-Figure 5 The utility model provides a technical solution: a new type of grid bolt ball node, comprising a grid body 1, a threaded groove is provided in the grid body 1, and a ball 3 is connected to the top of a first bolt 2;

[0029] The first bolt 2 is disposed in the telescopic member 5 and is hinged to the inner part of the telescopic member 5;

[0030] The telescopic member 5 is connected to the positioning member 4 , the positioning member 4 is installed on the side wall of the grid body 1 , and the telescopic member 5 is rotatably connected to the positioning member 4 .

[0031] The positioning member 4 includes a mounting plate 41 installed on the side wall of the truss body 1, a rotating shaft 42 rotatably connected to the mounting plate 41, a return spring 43 arranged in the mounting plate 41 and connected to the outer wall of the rotating shaft 42, an external thread 44 opened on the end of the rotating shaft 42 and a limiting sleeve 45 connected to the outer wall of the external thread 44. The rotating shaft 42 passes through one end of the outer wall of the mounting plate 41 and is provided with an external thread 44. The telescopic member 5 connected to the outer wall of the rotating shaft 42 includes a sleeve rod 51 connected to the outer wall of the rotating shaft 42, a movable rod 52 slidably connected in the sleeve rod 51, a limiting bolt 53 connected to the outer wall of the sleeve rod 51, and a hinged plate 54 hinged to the end of the movable rod 52; wherein the hinged plate 54 is rotatably connected with the first bolt 2.

[0032] When the two groups of grid bodies 1 are fitted and connected, the sleeve rod 51 drives the first bolt 2 to be at a vertical angle to the side wall of the grid body 1. This is to facilitate the stacking of multiple groups of grid bodies 1. The staff first twists the limiting sleeve 45 outward so that the limiting sleeve 45 moves outward on the external thread 44, releasing the lock on the rotating shaft 42. One end of the return spring 43 is connected to the inner wall of the mounting plate 41, and the other end of the return spring 43 is connected to the outer wall of the rotating shaft 42. At this time, the restoring force generated by the elasticity of the return spring 43 itself pushes the rotating shaft 42 to restore. The rotating shaft 42 pushes the sleeve rod 51 to restore, driving the first bolt 2 on the hinged plate 54 to rebound close to the thread groove;

[0033] It is worth noting that two sets of mounting plates 41 are symmetrically arranged on one side wall of the truss body 1. The rotating shaft 42 is rotatably connected within the two sets of mounting plates 41. A set of return springs 43 is provided within each set of mounting plates 41. The symmetrical arrangement can ensure the structural stability of the truss body 1 during connection and prevent structural deformation or damage due to uneven force on one side. The rotating shaft 42 can be rotatably connected within the two sets of mounting plates 41, which allows the position of the first bolt 2 to be fine-tuned during assembly to ensure its accurate alignment with the thread groove.

[0034] At this time, the position of the first bolt 2 can be adjusted according to the position of the thread groove corresponding to the first bolt 2 on the grid body 1, and the limiting bolt 53 can be loosened outward so that the inner end of the limiting bolt 53 is separated from the outer wall of the movable rod 52, thereby releasing the limit on the movable rod 52. At this time, the first bolt 2 can be pulled so that the first bolt 2 drives the hinge plate 54 to move outward, and the hinge plate 54 drives the movable rod 52 to extend outward in the limiting bolt 53. After adjusting the position, the ball 3 is rotated to drive the first bolt 2 to be fixed to the thread groove;

[0035] It is worth noting that the limit bolt 53 rotates inward to clamp the outer wall of the movable rod 52 to form a limit. The limit bolt 53 rotates inward to clamp the outer wall of the movable rod 52 to form a limit. This can ensure that the first bolt 2 will not move excessively during the assembly process, thereby ensuring the accuracy of the assembly. By turning the limit bolt 53, the operator can easily control the movement of the movable rod 52, and then adjust the position of the first bolt 2.

[0036] The above description is only a preferred embodiment of the present invention and does not limit the present invention in any other form. Any technician familiar with the profession may use the technical content disclosed above to change or modify it into an equivalent embodiment with equivalent changes for application in other fields. However, any simple modification, equivalent change and modification of the above embodiment made according to the technical essence of the present invention without departing from the content of the technical solution of the present invention shall still fall within the scope of protection of the technical solution of the present invention.
