[0021] The following is a further detailed description of the implementation of the present invention in conjunction with the accompanying drawings and examples. The following examples are used to illustrate the present invention, but cannot be used to limit the scope of the present invention.

[0022] like Figure 1-4As shown, the utility model provides an adjustable steel structure connection device, including a connecting plate 1, two limit plates 2 are symmetrically arranged on one side of the connecting plate 1, and the two connecting plates 1 are installed with connecting rods 3, the width of the connecting rod 3 is equal to the distance between the two limit plates 2, and the connecting rod 3 is connected with a rotating shaft 4 near one end of the connecting plate 1, and the two ends of the rotating shaft 4 are respectively connected to the two limit plates 2 for rotation, and the limit plates 2 are provided with arc-shaped movable grooves 5 on the surface, and the opposite sides of the two limit plates 2 are provided with limiting circular grooves 6, and installation grooves 7 are provided on both sides of the connecting rod 3, and limiting pins 8 are installed inside the installation grooves 7, one end of the limiting pin 8 passes through the installation groove 7, and the end face of the passing end is provided with a pressing head 9, and the length of the pressing head 9 is greater than the thickness of the limit plate 2.

[0023] The arc movable groove 5 is arranged through and the center of the arc movable groove 5 is located on the central axis of the rotating shaft 4. The angle between the two ends of the arc movable groove 5 and its center is 180 degrees, so that the connecting rod 3 can be adjusted within a range of 180 degrees.

[0024] Among them, there are multiple limiting circular grooves 6 on the opposite sides of the two limiting plates 2, and the multiple limiting circular grooves 6 are evenly distributed on the path of the arc-shaped movable groove 5. The multiple limiting circular grooves 6 make it convenient for the limiting pin 8 to engage with different limiting circular grooves 6 when the connecting rod 3 is at different angles.

[0025] Among them, the diameter of the limiting circular groove 6 is larger than the width of the arc-shaped movable groove 5. When the limiting pin 8 is inserted into the limiting circular groove 6, the angle of the connecting rod 3 can be fixed, and the limiting pin 8 is adapted to the shape and size of the limiting circular groove 6, which is convenient for the limiting pin 8 and the limiting circular groove 6 to engage with each other, and the distance between the limiting pin 8 and the rotating shaft 4 is equal to the radius of the arc-shaped movable groove 5.

[0026] The shape and size of the pressing head 9 are smaller than the width of the arc-shaped movable groove 5 . As the angle of the connecting rod 3 changes, the pressing head 9 can move inside the arc-shaped movable groove 5 .

[0027] Among them, a spring 10 is installed inside the installation groove 7, and the two ends of the spring 10 are respectively against the side of the limit pin 8 away from the pressing head 9 and the inner wall of the installation groove 7 on the opposite side thereof. The limit pin 8 is reset by the spring 10. At the same time, the elastic force of the spring 10 can keep the limit pin 8 in the limit circular groove 6, thereby fixing the angle of the connecting rod 3.

[0028] Among them, two limiting grooves 11 are symmetrically arranged on the inner wall of the installation groove 7, and two limiting prisms 12 are symmetrically arranged on the end of the limiting pin 8 away from the pressing head 9. The limiting prisms 12 are adapted to the shapes and sizes of the limiting grooves 11, and the two limiting prisms 12 are respectively inserted into the two limiting grooves 11. The limiting pin 8 is limited by the limiting prisms 12 and the limiting grooves 11 to prevent the limiting pin 8 from falling off.

[0029] Specific working principle:

[0030] When the utility model adjusts the angle of the connecting rod 3 in the steel structure, first press the pressing heads 9 located on both sides of the movable rod, and by pressing the pressing heads 9, the limit pins 8 are moved toward the inner side of the installation groove 7, so that the limit pins 8 are withdrawn from the limit circular groove 6. At this time, only the pressing heads 9 are located in the arc-shaped movable groove 5, so that the connecting rod 3 can be rotated around the rotating shaft 4, thereby facilitating the adjustment of the angle of the connecting rod 3. After the adjustment is completed, it is only necessary to release the pressing heads 9, and then under the action of the spring 10, the limit pins 8 rebound into the limit circular groove 6 again, and the fixing of the angle of the connecting rod 3 is achieved by the engagement of the limit pins 8 and the limit circular groove 6.

Although the embodiments of the present invention have been shown and described above, it can be understood that the above embodiments are exemplary and cannot be understood as limitations of the present invention. Ordinary technicians in this field can change, modify, replace and modify the above embodiments within the scope of the present invention.
