detailed description

The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of them. example.

The connector body 1 (the model is q235), the grid rod 2 (the model is 235) and the spring 13 (the model is JX110) mentioned in the utility model can be purchased from the market or obtained by private customization.

Please refer to Fig. 1 to Fig. 4, an embodiment provided by the utility model: a steel structure connection fastener for a network frame, including a connector body 1, the outer surface of the connector body 1 is provided with connection ports 4, The outer side of the connection port 4 is provided with a T-shaped ring groove 5 located on the outer surface of the connector body 1, an external threaded sleeve 7 is arranged above the T-shaped ring groove 5, and a T-shaped ring 6 is fixed on the lower end surface of the external threaded sleeve 7. The T-ring 6 is snapped into the inside of the T-ring groove 5, and the T-ring 6 and the T-ring groove 5 are connected by a roller bearing;

The top of the connector body 1 is provided with a grid rod 2, and the upper and lower sides of the outer surface of the grid rod 2 are provided with an internal thread connection port 9, and the position of the internal thread connection port 9 corresponds to the position of the external thread sleeve 7. The external thread of the external thread sleeve 7 corresponds to the internal thread of the internal thread connection port 9, the outer surface of the external thread sleeve 7 is closely attached to the inner wall of the internal thread connection port 9, and the passage between the external thread sleeve 7 and the T-shaped ring 6 Welding connection; when in use, the external thread sleeve 7 is connected with the connector body 1 through a roller bearing structure, and the internal thread connection port 9 located on the outer surface of the grid rod 2 is aligned with the external thread located on the outer surface of the connector body 1 The sleeves 7 are then close to each other. When the external thread sleeve 7 touches the entrance of the internal thread connection port 9, the external thread sleeve 7 is rotated. Since the external thread of the external thread sleeve 7 matches the internal thread of the internal thread connection port 9, so With the rotation of the external thread sleeve 7, the external thread sleeve 7 will enter the interior of the internal thread connection port 9, thereby connecting the connector body 1 with the grid rod 2, due to the connection between the external thread sleeve 7 and the connector body 1 The space is connected by roller bearings, so when the connection is completed, as long as the grid pole 2 is not fixed, no matter how the grid pole 2 rotates, the connection between the connector body 1 and the grid pole 2 will not occur loose;

The inner wall of the connecting port 4 is provided with an annular fixing groove 10, and the middle position of the upper and lower end surfaces of the grid rod 2 is fixed with a connecting head 3, the outer surface of the connecting head 3 is closely attached to the inner wall of the connecting port 4, and the connecting head 3 It is integrated with the grid rod 2. The inside of the connector 3 is provided with a spring groove 11. Both sides of the inner wall of the spring groove 11 are provided with a port 12 extending to the outer surface of the connector 3. The spring groove 11 The inside of the spring 13 is provided with a spring 13, and the two ends of the spring 13 are connected with a hemispherical fixed block 14, and the opposite faces of the two hemispherical fixed blocks 14 are provided with a circular groove, and the two ends of the spring 13 are connected with the circular groove. The inner wall of the annular fixing groove 10 is in contact with the position of the hemispherical fixing block 14.
