[0020] 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.

[0021] The utility model provides a hidden 500kg hook, such as Figure 1-Figure 3 As shown, it includes a shell 1, and two hanging ring extension openings 11 are arranged on the top of the shell 1 for the hanging ring 2 to extend. A hanging ring 2 is arranged inside the shell 1, and the upper part of the hanging ring 2 extends from the hanging ring extension opening 11. A limit stopper 3 is installed in the middle of the inner part of the shell 1. The hanging ring 2 limits the upper and lower movable range through the limit stopper 3. The limit stopper 3 is positioned by the screw rod 4. When the screw rod 4 rotates, it can drive the limit stopper 3 to move up and down for position adjustment, thereby realizing the limitation of the extension length of different hanging rings 2.

[0022] In this embodiment, four locking bolts 12 are installed on the front side of the shell 1 near the corners, and a locking opening 14 is provided on the surface of the shell 1 near the locking bolts 12. The end of the locking bolt 12 passes through the locking opening 14 and the shell 1 is installed on the threaded hole of the external device through threads, so that the shell 1 is conveniently fixed to the equipment that needs to be hoisted.

[0023] Specifically, a notch 13 is provided at the bottom of the housing 1 to facilitate manual adjustment of the rotation of the screw rod 4 .

[0024] Furthermore, a positioning plate 15 is installed on the bottom inner wall of the shell 1 near the outer side of the screw rod 4. The bottom end of the screw rod 4 is rotatably connected to the positioning plate 15 through a bearing, and the top end of the screw rod 4 is rotatably connected to the upper inner wall of the shell 1 through a bearing. An opening is provided at the lower end of the hanging ring 2, and the screw rod 4 passes through the opening to ensure that the screw rod 4 can rotate flexibly.

[0025] Furthermore, a knob 41 is installed at the bottom end of the screw rod 4 to facilitate adjustment of the screw rod 4 by turning.

[0026] Furthermore, a threaded through hole is provided in the middle of the limit stopper 3, and the screw rod 4 is threadedly connected to the threaded through hole. The screw rod 4 rotates to drive the limit stopper 3 to move up and down, thereby limiting the different activity ranges of the hanging ring 2.

[0027] Furthermore, a groove 31 is provided at the bottom of the limit stop 3, and the shape of the groove 31 is adapted to the shape of the lower surface of the hanging ring 2, so that when the hanging ring 2 is hoisted, the bottom end can fit under the limit stop 3 to ensure positioning and prevent the hanging ring 2 from shaking.

[0028] Furthermore, the upper and lower ends of the hanging ring 2 are semicircular ring structures, which are convenient for cooperation with the hook for lifting operations.

[0029] When the hidden 500kg hook of the utility model is in use, first, the shell 1 of the hook serves as a protection and support structure of the entire device, and the two hanging ring extension openings 11 at the top thereof allow the hanging ring 2 to extend. The hanging ring 2 arranged inside the shell 1 can move up and down, but its range of movement is limited by the limit stopper 3.

[0030] When the extension length of the hanging ring 2 needs to be adjusted, the screw rod 4 can be operated. The screw rod 4 is rotatably connected through the positioning plate 15 on the bottom inner wall of the housing 1 and the bearing on the upper inner wall to ensure the stability and flexibility of its rotation. A knob 41 is installed at the bottom end of the screw rod 4 to facilitate manual rotation to adjust the position of the screw rod 4.

[0031] During the adjustment process, when the knob 41 drives the screw rod 4 to rotate, since the screw rod 4 is threadedly connected to the threaded through hole in the middle of the limit stopper 3, the rotational movement of the screw rod 4 is converted into the up and down linear movement of the limit stopper 3. By rotating the knob 41, the position of the limit stopper 3 can be accurately adjusted, thereby controlling the up and down range of movement of the hanging ring 2, and realizing accurate adjustment of the extension length of the hanging ring 2.

[0032] In addition, four locking bolts 12 installed on the front of the housing 1 are used to fix the housing 1 on the equipment that needs to be hoisted. By tightening the locking bolts 12, the stability and safety of the hook can be ensured.

[0033] During the hoisting process, the semicircular ring structures at the upper and lower ends of the hanging ring 2 cooperate with the external hook to realize the hoisting operation of the object. At the same time, the groove 31 at the bottom of the limit stopper 3 is adapted to the shape of the lower surface of the hanging ring 2, ensuring that the hanging ring 2 can be stably fitted under the limit stopper 3 during hoisting to prevent the hanging ring 2 from shaking and deflecting.

[0034] The above shows and describes the basic principle, main features and advantages of the utility model. Those skilled in the art should understand that the utility model is not limited by the above embodiments. The above embodiments and descriptions are only preferred examples of the utility model and are not used to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model may have various changes and improvements, which fall within the scope of the utility model to be protected. The scope of protection of the utility model is defined by the attached claims and their equivalents.
