[0002] Building construction refers to production activities during the implementation phase of engineering construction, which includes foundation construction, main structure construction, roof construction, decoration construction, etc. At the construction site, safety bolts are needed to connect and disassemble construction buildings or construction equipment to ensure the safety of the construction project.

[0003] At present, safety bolts are often connected to construction buildings through external wrenches. However, when the bolts are disassembled for a long time, the friction of the wrench on the hexagonal edges will cause the edges and corners between them to be worn flat. During the subsequent disassembly and assembly, the wrench is prone to slipping, which brings inconvenience to the subsequent disassembly and assembly work. Utility Model Content

[0021] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] See also Figure 1-4As shown, a construction safety bolt comprises a bolt body 1, a turntable 4 is arranged on the top of the bolt body 1, a groove 13 is opened on the top of the turntable 4, and the groove 13 is arranged in a cross shape, so that it is convenient to apply force to the turntable 4 by an external wrench, and a rotating rod 5 is fixedly connected to the bottom of the turntable 4, and the other end of the rotating rod 5 extends to the inside of the bolt body 1 and is movably connected to a cam 7, and the bottom of the cam 7 is rotatably connected to the inner wall of the bolt body 1, and both sides of the inner cavity of the cam 7 are provided with sliding grooves 8, and both sides of the rotating rod 5 are fixed. A slider 9 is fixedly connected, and the surface of the slider 9 is slidably connected to the inside of the slide groove 8. Push plates 2 are provided on both sides of the inside of the bolt body 1, and top plates 3 are hinged on the front and rear sides of the opposite sides of the left and right push plates 2. The movable distance of the cam 7 protrusion is the same as the distance between the push plate 2 and the inner wall of the bolt body 1. In this way, when the protruding part of the cam 7 rotates to the position of the push plate 2, force can be applied to push the push plate 2, so that the push plate 2 approaches the inner wall of the bolt body 1, and the surface of the top plate 3 is movably connected to the corner inside the bolt body 1.

[0023] The front and rear sides of both sides of the bolt body 1 are fixedly connected with fixing rods 14, and the surface of the fixing rods 14 is movably connected to the inside of the push plate 2, so that the push plate 2 can be auxiliary supported and its stability during movement can be maintained.

[0024] Limiting grooves 11 are provided on the front and rear sides of both sides of the top of the bolt body 1, and a circular groove 10 is connected below the limiting groove 11. Limiting blocks 12 are fixedly connected to both sides of the turntable 4, and the limiting blocks 12 are used in conjunction with the limiting grooves 11 and the inside of the circular grooves 10. In this way, the limiting grooves 11 can be used to limit the limiting blocks 12 to prevent the turntable 4 from being rotated at will. If the turntable 4 is rotated, the turntable 4 will be pressed downward at this time, and the limiting blocks 12 will enter the inside of the circular grooves 10 through the limiting grooves 11, thereby facilitating the turntable 4 to rotate.

[0025] A spring 6 is fixed inside the cam 7, and the top of the spring 6 is fixed to the bottom of the rotating rod 5. In this way, the elastic force of the spring 6 can drive the rotating rod 5 and the turntable 4 to always move upward, so as to limit the position of the turntable 4 after the movement.

[0026] It is worth noting that: the technical features proposed in this technical solution should be regarded as prior art, and the specific structure, working principle, and possible control method and spatial layout method of these technical features can be selected by conventional methods in the field, and this technical solution will not be further elaborated.

[0027] Working principle: before rotating the bolt body 1, you can use an external cross wrench to align the groove 13, and then press the turntable 4 downward to make the limit block 12 enter the inside of the circular groove 10 through the limit groove 11, then rotate the turntable 4, and drive the rotating rod 5 and the cam 7 to rotate, so that the protruding part of the cam 7 rotates to the position of the push plate 2, and then the push plate 2 will move outward and drive the top plate 3 to move together, so that the top plate 3 protrudes from the corners of the bolt body 1, and then release the turntable 4. At this time, the turntable 4 is bounced up, and the limit block 12 re-enters the inside of the limit groove 11 for limiting, and then the staff can rotate it with a wrench. After the rotation is completed, the above operation can be repeated to re-store the top plate 3 into the inside of the bolt body 1.
