[0029] The storage slot 11 is provided at the top of the rotating slot 10 and is used to store the top and bottom hooks 2;

[0030] A blocking member is provided at the bottom of the receiving slot 11 and is used to prevent the top and bottom hooks 2 from sliding out of the receiving slot 11;

[0031] The positioning member is arranged at one end of the rotating groove 10 and is used to limit the rotation of the rotating drum 3.

[0032] Specifically, the lock body 1 is an existing stainless steel three-proof lock body with fireproof, explosion-proof and saw-proof design. The top and bottom hooks 2 are curved hooks made of existing metal materials. The top and bottom hooks 2 are L-shaped. Two top and bottom hooks 2 are set, which are symmetrically arranged at the top and bottom of the lock body 1 respectively.

[0033] Specifically, a round rod 4 is provided inside the rotating groove 10, and the two ends of the round rod 4 are fixedly connected to the inner wall of the rotating groove 10 respectively. A circular through groove is provided at one end of the rotating drum 3, and the rotating drum 3 is sleeved on the outer wall of the round rod 4. The end of the sky and earth hook 2 is fixedly connected to the outer wall of the rotating drum 3, and the direction in which the sky and earth hook 2 is set is parallel to the center line direction of the circular through groove of the round rod 4. One end of the storage groove 11 is connected with one end of the rotating groove 10. The vertical cross-section of the storage groove 11 is L-shaped. A strip groove for installing a blocking member is provided on one side of the bottom of the storage groove 11. The blocking member includes a baffle 7. The baffle 7 is inserted into the interior of the strip groove. A first circular hole is provided at one end of the baffle 7, and the interior of the first circular hole is sleeved with A rotating column 8, one end of the rotating column 8 is fixedly connected to the inner wall of the strip groove, a second circular hole is opened at the other end of the baffle 7, a first threaded groove is opened on one side of the inner wall of the strip groove, a second bolt 9 is inserted and connected inside the second circular hole, the second bolt 9 is threadedly inserted and connected with the first threaded groove, the positioning part includes a first bolt 6, a limiting groove 12 is opened on the outer wall of the rotating cylinder 3 for inserting the limiting block 5, a mounting groove 13 for installing the first bolt 6 is opened on one side of the lock housing 1, a second threaded groove is opened on the inner wall of the mounting groove 13, a second circular hole is opened on one side of the limiting block 5, the first bolt 6 is inserted and connected inside the second circular hole, the first bolt 6 is threadedly inserted and connected with the second threaded groove.

[0034] Furthermore, the number of the receiving grooves 11, the strip grooves, the rotating grooves 10, the blocking members and the positioning members is the same as the number of the sky and earth hooks 2. The two receiving grooves 11, the two rotating grooves 10, the two strip grooves, the two limiting grooves 12 and the two mounting grooves 13 are symmetrically opened at the top and bottom of the lock housing 1, respectively. The two ends of the round rod 4 are respectively welded to the inner wall of the rotating groove 10, and the contact part of the rotating cylinder 3 with the sky and earth hook 2 is fixed by welding. The shape of the receiving groove 11 is the same as that of the sky and earth hook 2. The size of the receiving groove 11 is 1.2 times the size of the sky and earth hook 2, the size of the strip groove is 1.1 times the size of the baffle 7, and the rotating column One end of 8 is welded and fixed to the inner wall of the strip groove, the horizontal cross-section of the rotating column 8 is T-shaped, one end of the rotating column 8 is inserted into the first circular hole of the baffle 7, and the outer wall of the rotating column 8 is a smooth surface, so that the baffle 7 rotates with the rotating column 8 as the center of the circle. The thread of the outer wall of the second bolt 9 is engaged with the thread of the inner wall of the first thread groove. The outer diameter of the screw of the second bolt 9 is 0.98 times the diameter of the second circular hole, and the size of the nut of the second bolt 9 is 1.1 times the diameter of the second circular hole. The dimensions of the vertical cross-sections of the mounting groove 13 and the limiting groove 12 are the same, both being 1.1 times the size of the limiting block 5. The thread of the inner wall of the second thread groove is engaged with the thread of the first thread groove. The threads on the outer wall of the bolt 6 are engaged with each other, the outer diameter of the first bolt 6 is 0.98 times the diameter of the second circular hole, and the nut diameter of the first bolt 6 is 1.1 times the diameter of the second circular hole. When the rotating drum 3 is rotated to drive the sky hook 2 into the storage groove 11, the second bolt 9 is inserted into the second circular hole by rotating the baffle 7 to the strip groove, and the second bolt 9 is rotated and inserted into the first threaded groove, thereby fixing the baffle 7 to prevent the sky hook 2 from moving out of the storage groove 11 to form a lock housing 1 without a hook. When the sky hook 2 needs to be used, the second bolt 9 is removed and the rotating drum 3 is rotated to drive the rotating drum 3 to drive the sky hook 2 to move out of the storage groove 11. The top and bottom hook 2 is moved to the outside of the lock housing 1, and then the limiting block 5 is inserted into the inside of the installation groove 13 and the limiting groove 12. Under the action of the limiting block 5, the top and bottom hook 2 is set vertically to the end of the lock housing 1, and at the same time, the rotation of the rotating drum 3 is limited. Then the first bolt 6 is passed through the second circular hole and connected with the second threaded groove to fix the limiting block 5. In this way, it can cope with the situation where the door body has or does not have a top and bottom rod. When there is a top and bottom rod, the top and bottom hook 2 is turned out. When there is no top and bottom rod, the top and bottom hook 2 is rotated into the storage groove 11, thereby improving the applicability of the lock housing 1, and there is no need to return or exchange the lock housing 1.
