[0040] The utility model is further described in conjunction with the following embodiments.

[0041] Example 1.

[0042] like Figure 1-2 As shown, a fastening and anti-dropping workshop crane hook comprises a hook housing 1, a support column 2 is installed through the center of the hook housing 1, a hook connecting rod 3 is movably installed on the support column 2, and an anti-dropping hook 4 is installed on the hook connecting rod 3;

[0043] The two groups of hook housings 1 are connected by a support column 2 installed between them. At the same time, a hook connecting rod 3 movably installed on the support column 2 is hung with an anti-drop hook 4 at the bottom, and the anti-drop hook 4 can be used to lift materials.

[0044] The anti-drop hook 4 comprises a bidirectional hook head 5 and a hook mounting portion 6. A limiting groove 7 is provided inside the bidirectional hook head 5, and an anti-drop groove 8 is provided below the limiting groove 7.

[0045] The anti-drop hook 4 is divided into two parts, including a bidirectional hook head 5 and a hook mounting portion 6. The limiting groove 7 and the anti-drop groove 8 opened inside the bidirectional hook head 5 can prevent the lifted material from being dropped off, and at the same time play an anti-drop protection role.

[0046] An anti-slip mechanism 9 is installed inside the hook mounting portion 6, and the anti-slip mechanism 9 is installed in cooperation with the bidirectional hook head 5. The anti-slip mechanism 9 includes an anti-slip baffle 10, one end of the anti-slip baffle 10 is connected to the inside of the limiting groove 7, and the other end of the anti-slip baffle 10 extends into the inside of the hook mounting portion 6. A rotating shaft 11 is installed on the anti-slip baffle 10, and the anti-slip baffle 10 is penetrated inside the rotating shaft 11. A rotating plate 13 is integrally formed at the top of the anti-slip baffle 10, and two sets of positioning protrusions 12 are provided on the rotating plate 13;

[0047] The anti-slip mechanism 9 arranged inside the hook mounting part 6 prevents the lifted material from being detached by installing an anti-slip baffle 10. The anti-slip baffle 10 is combined with an integrally formed rotating plate 13 and can rotate when the material is lifted. Through the rotating shaft 11 installed on the anti-slip baffle 10, the two groups of positioning protrusions 12 arranged on the rotating plate 13 can be combined with the two groups of limit blocks 14 inside the hook mounting part 6 when the anti-slip baffle 10 rotates, thereby realizing the position movement of the anti-slip baffle 10 and the rotating plate 13.

[0048] Two sets of limit blocks 14 are arranged at both ends of the hook mounting part 6 , a connecting base is installed between the limit blocks 14 , and a rigid spring 20 is arranged on the connecting base.

[0049] The connection base provided in the hook mounting portion 6 can support the rigid spring 20 . The provision of the rigid spring 20 can reset the rotating plate 13 and can buffer the pressure of the rotating plate 13 to realize the closing and opening of the anti-slip baffle 10 .

[0050] A positioning groove 15 is formed at the top of the limiting block 14 . An anti-collision pad 16 is arranged inside the positioning groove 15 . The positioning groove 15 is installed in cooperation with the positioning protrusion 12 .

[0051] After the rotating plate 13 is rotated under force, the positioning protrusion 12 can be combined with the limiting block 14, and the positioning protrusion 12 will enter the positioning groove 15 opened on the limiting block 14. At the same time, the anti-collision pad 16 in the positioning groove 15 plays a good anti-collision role, thereby improving safety.

[0052] The anti-slip baffle 10 and the rotating plate 13 are integrally formed and installed, and the rotating shaft 11 is arranged in the center of the anti-slip baffle 10 and the rotating plate 13, and the angle between the anti-slip baffle 10 and the rotating plate 13 is an obtuse angle.

[0053] A circular arc groove 17 is arranged at the top of the rotating plate 13, and the circular arc groove 17 is installed corresponding to the rigid spring 20. The circular arc groove 17 arranged at the top of the anti-slip baffle 10 can prevent the rotating plate 13 from deflecting when contacting with the rigid spring, and play a limiting role on the rigid spring.

[0054] The anti-slip groove 8 includes a rectangular space 18, and an anti-collision layer 19 is evenly arranged inside the rectangular space 18. During the material lifting process, the rectangular space 18 can play a limiting role in preventing shaking, thereby improving the fastening effect. At the same time, the anti-collision layer 19 in the rectangular space 18 can play a good protective role and improve the safety of the hook.

[0055] During the production process, the hook is tightened and prevented from falling off by means of the anti-falling mechanism 9 installed inside the bidirectional hook head 5 and the hook mounting part 6. The anti-falling baffle 10 cooperates with the upper limit groove 7 on the bidirectional hook head 5 to achieve locking and anti-falling. At the same time, the anti-falling baffle 10 is installed and released through the transmission of the rotating plate 13 combined with the rigid spring 20 installed on the hook mounting part 6. Adding anti-collision pads 16 and anti-collision layers 19 to the anti-falling mechanism 9 can reduce collision wear, improve the use efficiency of the hook, and increase safety.

[0056] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model rather than to limit the protection scope of the utility model. Although the utility model is described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
