[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] This utility model provides a technical solution, please refer to Figure 1 and Figure 2A quick-release building material lifting device includes: a locking mechanism 1, a base plate 2, and a top plate 3. The base plate 2 and the top plate 3 are respectively assembled at opposite ends of the two locking mechanisms 1. The locking mechanism 1 includes a locking block 11. A rotating block 12 is rotatably connected inside the locking block 11. A lever 13 is connected to the outside of the rotating block 12. A spring 14 is connected to the outside of the lever 13. The spring 14 is connected to the inner cavity of the locking mechanism 1. A locking tongue 16 is assembled on the top of the locking block 11. A magnet assembly 19 is assembled on the outside of the lever 13. The magnet assembly 19 includes two sets of magnets. The two sets of magnets are respectively connected to the lever 13 and the inner cavity of the locking block 11.

[0022] Please see Figure 3 and Figure 4 The base plate 2 can be connected to the materials to be hoisted with ropes, the top plate 3 can be connected to the lifting equipment, the locking block 11 can support the rotating block 12 and the lever 13, the rotating block 12 can rotate inside the square groove 18, the lever 13 can allow the worker to drive the rotating block 12 to rotate, the spring 14 can pull the rotating block 12 to return to its original position after the movement is completed, and the locking tongue 16 can drive the rotating block 12 to move, so that the two rotating blocks 12 can be locked together.

[0023] Pins 21 are evenly inserted on the outside of the base plate 2. The pins 21 are fitted with anti-slip texture. The pins 21 improve the stability of the connection between the base plate 2 and external objects. A square groove 18 is opened inside the lock block 11. The square groove 18 is connected to the rotating block 12 through a bearing with a seat. The square groove 18 is connected to the spring 14. The square groove 18 facilitates the rotation of the rotating block 12 and can also store the lock tongue 16.

[0024] The locking block 11 has an inclined groove 15 inside, which is connected to the magnet. The inclined groove 15 facilitates the rotation of the lever 13 and also fixes the magnet. The locking tongue 16 has a C-shaped groove 17 inside, which is slidably connected to the rotating block 12. The C-shaped groove 17 facilitates the rotation of the rotating block 12. The lever 13 includes a long arm, which is covered with a rubber sleeve. The rubber sleeve facilitates the movement of the lever 13 and improves the service life of the lever 13.

[0025] This solution first connects the top plate 3 to the lifting equipment and the bottom plate 2 to the items to be hoisted. The locking tongue 16 at one end is inserted into the square groove 18 inside the locking mechanism 1 at the other end. When the locking tongue 16 moves, the two rotating blocks 12 will rotate. After the locking tongue 16 is fully inserted, the two rotating blocks 12 will be fully returned to their original position by the pull of the spring 14, thereby locking the two locking blocks 11 together. At the same time, the added magnet group 19 prevents the lever 13 from being accidentally returned to its original position during use. When it is necessary to disassemble the two locking mechanisms 1, swinging the lever 13 at one end will drive the rotating block 12 to rotate, thereby canceling the mutual locking between the two locking mechanisms 1.

[0026] By adding a rotating block 12, a lever 13, a spring 14, and a locking tongue 16, the two locking mechanisms 1 are quickly locked, which greatly improves the assembly speed and prevents the locking mechanism 1 from becoming loose due to shaking of the items during hoisting. At the same time, the added magnet group 19 locks the lever 13 by magnetic attraction, preventing the lever 13 from being accidentally returned to its original position during use.
