[0020] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. 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.

[0021] Please see Figure 1-4 This utility model provides a technical solution: a steel truss support device for hoisting cheese boards, including uprights 1, horizontal bars 4, pin assemblies 7, and diagonal bars 8. The number of uprights 1 and horizontal bars 4 is several. The several uprights 1 are arranged in two vertically parallel rows, and the several horizontal bars 4 are arranged in four horizontal rows. The several horizontal bars 4 are arranged in a rectangular frame surrounding the two rows of uprights 1. The several uprights 1 and horizontal bars 4 are combined to form a grid frame as the basic load-bearing structure for hoisting the steel truss, forming a stable three-dimensional support system, providing overall support for the cheese board and the hoisting equipment above. The grid distribution can evenly distribute the load and avoid excessive local stress that could cause deformation of the cheese board or the lower structure.

[0022] A row of connecting seats 3 is welded on the upright 1. The connecting seats 3 are arranged in a "V" shape. The open end of the "V" shaped plate is welded to the outer wall of the upright 1. There are several connecting seats 3, which are evenly distributed on the upright 1 in groups of four. The four connecting seats 3 are arranged in a cross shape, serving as the connection node between the upright 1 and the crossbar 4, providing connection interfaces in four directions, and realizing multi-directional connection of the crossbar 4 in the horizontal direction. A "V" shaped through hole is provided between the V-shaped connecting seat 3 and the outer wall of the upright 1, which provides precise positioning for the subsequent fixing of the pin assembly 7 and enhances the connection stability.

[0023] Both ends of the crossbar 4 are welded with insert plates 5, and slots 6 are opened through the insert plates 5. The crossbar 4 is snapped into the connecting seat 3 through the insert plates 5. The insert plates 5 are set in the shape of "C" plate. Slots 6 are opened through the corresponding positions of the two extended ends of the "C" plate. The bottom surface of the inner wall of the upper extended end of the insert plate 5 abuts against the top of the connecting seat 3. The position of the slot 6 matches the position of the "V" shaped through hole. The C-shaped insert plate 5 is snapped into the connecting seat 3 and then fixed by the triangular pin body 701. The pin assembly 7 is in the shape of a triangular plate. The bottom end of the pin assembly 7 passes through the slot 6 on the upper extended end of the insert plate 5, the "V" shaped through hole and the slot 6 on the lower extended end of the insert plate 5 in sequence and extends to the bottom of the insert plate 5. This realizes the quick snapping and mechanical locking of the crossbar 4 and the upright 1. After the pin passes through, it forms a rigid fixation to prevent the crossbar 4 from falling off or shaking, and improves the connection efficiency and firmness.

[0024] A support plate 2 is attached to the horizontal bar 4, which expands the bearing surface of the grid frame. Both ends of the diagonal bar 8 are connected to the buckle seat 9 by bolt thread. The diagonal bar 8 is snapped to one side of the vertical bar 1 by the buckle seat 9. There are four diagonal bars 8. The diagonal bars 8 are set at an angle. Both ends of the diagonal bar 8 are snapped to the intersection of the vertical bar 1 and the horizontal bar 4 by the buckle seat 9. The diagonal bars 8 enhance the anti-lateral displacement ability of the grid frame. The four diagonal bars 8 are located on the four outer surfaces of the grid frame composed of several vertical bars 1 and horizontal bars 4. The diagonal bars 8 form lateral support, reduce the shaking or deformation of the grid frame during hoisting, and improve the overall stability.

[0025] The pin assembly 7 is inserted into the slot 6. The pin assembly 7 includes a pin body 701. A groove 702 is formed in the lower part of the pin body 701. A rotating shaft 703 is rotatably connected to the bottom surface of the inner wall of the groove 702. A locking block 704 is installed on the rotating shaft 703. A spring 705 is provided on the upper part of the locking block 704. The other end of the spring 705 is connected to the inner wall of the groove 702. The groove 702 is rectangular. The locking block 704 is rotatably connected to the inside of the groove 702 through the rotating shaft 703. The cross-section of the locking block 704 is triangular inclined plate, and the tip of the triangular inclined plate of the locking block 704 faces the groove. Above the opening 702, a locking block 704 is positioned with its top end abutting against the top surface of the inner wall of the groove 702. A spring 705 is located between the groove 702 and the locking block 704. When the pin body 701 passes through the connecting seat 3 and the insert plate 5, the locking block 704 is pressed by the hole wall and retracts into the groove 702. After it is fully inserted, when the locking block 704 protrudes from the outside of the insert plate 5, the spring 705 pops the locking block 704 out. The top end of the locking block 704 is engaged with the outside of the insert plate 5, which can automatically lock and facilitate disassembly, preventing the pin from loosening or falling off under vibration or external force. To disassemble, simply press the locking block 704 to pull it out.
