[0022] Hereinafter, a ladder frame universal fixed connecting piece according to the utility model is specifically described with reference to the drawings.

[0023] As Figure 1 , Figure 2As shown, a ladder frame universal fixed connecting piece, comprising a main body 100 and an interface 200, further comprising a rotating structure 300, the rotating structure 300 comprises a fixed seat 301 and a rotating arm 302, the fixed seat 301 is arranged on the main body 100, the fixed seat 301 is connected with the main body 100 in the rotating structure 300, the rotating arm 302 is connected with the fixed seat 301 through a rotating shaft 303, giving the interface 200 flexible rotation ability, so that the connecting piece can adapt to different installation angle requirements, greatly improving the installation flexibility. The main body 100 and the rotating arm 302 are provided with a circular hole 101, and a screw 102 is arranged in the circular hole 101. The interface 200 is arranged on the main body 100 and the end of the rotating arm 302 respectively. The rotating arm 302 is provided with a rotating shaft 303, and the rotating arm 302 is connected with the fixed seat 301 through the rotating shaft 303. The interface 200 is provided with a notch 201, and a limiting pin 202 is arranged in the interface 200. The limiting pin 202 can be inserted into the notch 201, ensuring that the limiting pin 202 can apply pressure to the ladder frame from the inside, thereby achieving the effect of fastening.

[0024] As shown in the figure, Figure 6 The main body 100 is provided with at least one interface 200, and the main body 100 is connected with at least one rotating arm 302. The main body 100 can be provided with multiple interfaces 200 and connected with more than one rotating arm 302. The length, shape and load bearing requirements of the ladder frame can be flexibly selected according to the connection point and quantity, improving the connection stability while adapting to different specifications of the ladder frame.

[0025] Further, two rotating arms 302 can be directly connected to form an adjustable angle one-character fixed connecting piece.

[0026] As shown in the figure, Figure 3 The fixed seat 301 and the rotating arm 302 are provided with protrusions 304 for guiding and limiting, and the two sides of the protrusions 304 have an inclination angle. During the rotation of the rotating arm 302, the protrusions 304 play a guiding role, guiding the rotating arm 302 to rotate smoothly around the rotating shaft 303, ensuring the stability and controllability of the rotation process, and the blocking surface formed by the inclination angle precisely limits the rotation range of the rotating arm 302, preventing it from rotating excessively, thereby improving the connection reliability.

[0027] Further, the fixed seat 301 is provided with a mounting seat, the rotating arm is provided with a mounting groove matched with the mounting seat, the mounting seat is provided with a groove matched with the rotating shaft, and a damping pad is arranged in the groove.

[0029] The supporting block 205 is arranged at the end of the same side of the limiting pin 202 as the limiting block 203, and can serve as a fulcrum. When the screw 102 applies pressure, the limiting block 203 extends from the notch 201, thereby applying pressure to the inside of the ladder frame, ensuring the tightness and stability of the connection between the ladder frame and the connecting piece.

[0030] As shown, Figure 5 The limiting groove 204 is arranged at the bottom of the limiting pin 202, and the position of the limiting groove 204 corresponds to the position of the circular hole 101. The screw 102 is a wave bead screw, and the limiting groove 204 matches the end of the screw 102. When the screw 102 is screwed, the end of the screw 102 is closely embedded in the limiting groove 204, thereby preventing the screw 102 from deviating or slipping during work, and ensuring the stability of the operation.

[0031] In this embodiment, as shown, Figures 1-4 The ladder frame is inserted into the interface 200 of the connecting piece body 100, the rotating structure 300 is rotated, the rotating arm 302 is adjusted to the required angle, and after the angle is adjusted, the ladder frame is inserted into the interface 200 on the rotating arm 302. The ladder frame is connected with the interface 200, the screws 102 on the body 100 and the rotating arm 302 are screwed, the screw 102 is tightened inward and applies pressure to the limiting pin 202, the limiting pin 202 under extrusion takes the supporting block 205 as a fulcrum, the limiting block 203 at the top of the front end of the limiting pin 202 is closely embedded in the notch 201 on the interface 200, strong extrusion force is generated on the inner wall of the ladder frame, firm friction force is formed at the connection of the ladder frame, and the stable connection of the ladder frame and the connecting piece is completed.
