Description

Technical Field

[0001] The present invention relates to the construction of a hook body; and more particularly to a cable hook for connecting steel cables. Background Technology

[0002] Existing steel cable hooks are heavy because the body is made of metal forging, and their weight cannot be reduced. However, there is a need for lightweight when using steel cable hooks. Therefore, the design must reduce the weight of the steel cable hook without sacrificing its strength and reducing the safety of use. Summary of the Invention

[0003] In view of this, the purpose of the present invention is to provide a cable hook that is provided with a hook-shaped element comprising a tube and a cable, thereby reducing the weight of the cable hook while maintaining strength and safety, and having the advantage of rapid manufacturing.

[0004] To achieve the above objectives, the present invention provides a steel cable hook, comprising a buckle base, a hook-shaped element, and a lever element. The buckle base has a body, with a pivot portion on one side of the opposite sides of the body and an insertion tube on the other side, the insertion tube containing an insertion hole. The hook-shaped element includes a hook-shaped tube, a steel cable, and a buckle head. The bottom end of the hook-shaped tube has a sleeve portion with a larger diameter, which is fitted around the insertion tube. The steel cable passes through the hook-shaped tube, with its bottom end inserted into the insertion hole. The sleeve portion, the insertion tube, and the steel cable are radially overlapping and convergent. The buckle head is fixed to the free end of the hook-shaped tube and engages with the free end of the steel cable, with an opening between the buckle head and the pivot portion. The lever element has two ends, one end pivotally connected to the pivot portion, and the other end disengaging from or hooking onto the buckle head to control the opening or closing of the opening.

[0005] The advantages of this invention are that the combination of the hook-shaped tube of the hook element and the steel cable can reduce the weight of the steel cable hook. Since the hook element and the buckle are connected by a reduced diameter, welding is not required, which can increase production efficiency and reduce processing costs. When the hook element is subjected to external force and the hook-shaped tube deforms, the steel cable fixed at both ends to the buckle and the insert can support the hook-shaped tube, increase the tensile strength of the hook element, and improve the strength of the steel cable hook to resist deformation and tensile strength, while taking into account the safety of the steel cable hook during use.

[0015] To more clearly illustrate the present invention, preferred embodiments are described in detail below with reference to the accompanying drawings. Please refer to... Figures 1 to 5 As shown, a preferred embodiment of the present invention is a steel cable hook 100, which includes a buckle seat 10 and a hook-shaped element 20 and a lever element 30 respectively coupled to the buckle seat 10, wherein:

[0016] The buckle 10 has a body 12, which is a metal plate and has a connecting hole 121 in the middle. The top of the body 12 has a pivot part 14 on one side of opposite sides and an insertion tube 16 on the other side. The insertion tube 16 is an upwardly extending tube and has an insertion hole 161 inside.

[0017] The hook-shaped element 20 includes a hook-shaped tube 22, a steel cable 24, and a buckle 26. The hook-shaped tube 22 is a tube bent into a hook shape, with its opposite ends defined as the bottom end and the free end. The bottom end of the hook-shaped tube 22 has a sleeve portion 221, the inner and outer diameters of which are larger than the rest of the hook-shaped tube 22. The sleeve portion 221 is fitted around the insertion tube 16. The steel cable 24 passes through the hook-shaped tube 22, and its opposite ends are defined as the bottom end and the free end. From the end, the bottom end of the steel cable 24 is inserted into the insertion hole 161. By applying pressure with a mold, the radially overlapping portions of the sleeve 221, the insertion tube 16, and the steel cable 24 are reduced in diameter and joined together, so that the hook tube 22 and the steel cable 24 are fixed to the insertion tube 16 of the buckle seat 10. The buckle head 26 is fixed to the free end of the hook tube 22, and the free end of the steel cable 24 is joined to the buckle head 26. There is an opening A between the buckle head 26 and the pivot part 14.

[0018] The lever element 30 has two ends. One end of the lever element 30 is pivotally connected to the pivot part 14, and the other end can selectively leave the buckle 26 or hook onto the buckle 26, thereby controlling the opening or closing of the opening A.

[0019] When the preferred embodiment described above is used, the steel cable is threaded through the connecting hole 121 of the buckle 10, and the steel cable hook 100 is set to a state where the lever element 30 can be pushed open to open the opening A. After the hook-shaped element 20 is fastened to the fixed position, the lever element 30 is moved to a state where the hook is positioned with the buckle head 26, thus completing the operation of setting the steel cable hook 100. The advantage of the steel cable hook 100 described above is that, since the hook-shaped element 20 is not a solid metal, but includes a tubular hook-shaped tube 22, a steel cable 24 threaded inside the hook-shaped tube 22, and a buckle head 26 connected to the free end of the hook-shaped tube 22, the weight of the hook-shaped element 20 is lighter than that of a solid metal hook. After being assembled with the buckle 10, the overall weight of the steel cable hook 100 can be reduced, achieving a lightweight effect. Furthermore, since the hook-shaped element 20 and the buckle 10 are joined by a diameter reduction process, there is no need for welding or other operations that require skilled workers, thus increasing production efficiency and reducing processing costs.

[0020] Besides reducing weight, the present invention also maintains the same level of safety. Because the bottom end of the steel cable 24 is necked and connected to the buckle 10, and the buckle 26 connected to the free end of the steel cable 24 is hooked and engaged with the lever element 30 pivotally connected to the buckle 10, when the hook-shaped element 20 is subjected to external force causing the hook-shaped tube 22 to deform, the insertion tube 16 and the buckle 26 hooked by the lever element 30 can fix both ends of the steel cable 24. This provides the steel cable 24 with the force supporting the hook-shaped tube 22, increasing the strength of the hook-shaped element 20 against deformation and its tensile strength, thus improving the safety of the steel cable hook 100 during use.

[0021] For further explanation of the structure of the above preferred embodiments, please refer to [link / reference]. Figures 1 to 5 As shown, a flange 162 is provided between the outer peripheral surface of the insertion tube 16 and the surface of the body 12. The flange 162 surrounds the bottom end of the insertion tube 16. When the sleeve portion 221 of the hook-shaped tube 22 is fitted onto the insertion tube 16, the sleeve portion 221 is fitted to the position where its bottom edge is adjacent to the flange 162. The free end of the hook-shaped tube 22 forms an outer tube portion 222 with an inner and outer diameter larger than other parts. The buckle 26 has an outer insertion tube 261, which is inserted into the outer tube portion 222, forming an outer insertion hole 262 inside the outer insertion tube 261. The free end of the steel cable 24 passes through the outer insertion hole 262. By applying pressure with a mold, the radially overlapping portions of the outer tube portion 222, the outer insertion tube 261, and the steel cable 24 are reduced in diameter and joined together. The free end of the buckle 26 also has a top hook 263.

[0022] Please refer to Figures 6A to 6B As shown, the depth L1 of the insertion hole 161 along the axial direction of the insertion tube 16 is greater than the axial length L2 of the insertion tube 16 itself. In this preferred embodiment, the axial length L2 of the insertion tube 16 is defined as the shortest distance between the top edge of the insertion tube 16 and the flange 162. This ensures that the insertion hole 161 has sufficient length to allow the insertion of the steel cable 24. Furthermore, when the length L3 of the portion of the steel cable 24 that penetrates the insertion hole 161 is greater than the axial length L2 of the insertion tube 16 itself, the radial overlap of the sleeve portion 221, the insertion tube 16, and the steel cable 24 reaches its maximum.

[0023] Please refer to Figure 7A , 7B as well as Figure 6AAs shown, in this preferred embodiment, the inner diameter of the hook tube 22 is larger than the diameter of the steel cable 24, and the inner side of the hook tube 22 is the side of the hook tube 22 closer to the pivot portion 14, while the outer side of the hook tube 22 is the other side of the hook tube 22 farther away from the pivot portion 14. When the steel cable 24 is inserted into the hook-shaped tube 22, the difference between the length L4 of the portion of the steel cable 24 that is attached to the inner side of the inner wall of the hook-shaped tube 22 and located inside the hook-shaped tube 22 and the length L5 of the portion of the steel cable 24 that is attached to the outer side of the inner wall of the hook-shaped tube 22 and located inside the hook-shaped tube 22 is less than or equal to the difference between the axial depth L1 of the insertion hole 161 and the axial length L2 of the insertion tube 16 itself. When the difference between the axial depth L1 of the insertion hole 161 and the axial length L2 of the insertion tube 16 is defined as a steel cable deviation value, the ratio of the steel cable deviation value to the axial depth L1 of the insertion hole 161 is greater than or equal to 0.3 and less than or equal to 0.6.

[0024] Therefore, please refer to Figure 2 as well as Figures 6A to 6B As shown, when the hook-shaped element 20 is a hook-shaped tube 22 already combined with the buckle 26, and the free end of the steel cable 24 is connected to the buckle 26, when the sleeve part 221 is fitted onto the insertion tube 16, the length error of the bottom end of the steel cable 24 protruding from the sleeve part 221, that is, the ratio of the steel cable deviation value to the axial depth L1 of the insertion hole 161, will be greater than or equal to 0.3 and less than or equal to 0.6. This allows the steel cable 24 to extend into the insertion hole 161 at a more appropriate length when the hook-shaped element 20 is assembled on the buckle seat 10, avoiding the steel cable 24 not being inserted deep enough into the insertion hole 161, so that the sleeve part 221, the insertion tube 16 and the steel cable 24 can achieve a tighter fixing effect when they are combined with a reduced diameter.

[0025] The buckle 26, combined with the hook tube 22 and the steel cable 24, is constructed in the same way as the hook element 20 combined with the insertion tube 16. When the depth of the external insertion hole 262 along the axial direction of the external insertion tube 261 is greater than the axial length of the external insertion tube 261 itself, and the length of the steel cable 24 inserted into the external insertion hole 262 is greater than the axial length of the external insertion tube 261 itself, the radially overlapping portion of the sleeve 221, the insertion tube 16, and the steel cable 24 can reach its longest state, resulting in the tightest fixing effect when the three are combined with a reduced diameter.

[0026] Please refer to the following: Figure 3 , Figure 5 and Figure 8As shown, the lever element 30 has a lever body 32, one end of which is pivotally connected to the pivot part 14, and the other end forms a bottom hook 321. The bottom hook 321 can hook the top hook 263 from the inside. An annular groove 322 is provided around the lever body 32, and an elastic ring 323 is provided in the annular groove 322. A sleeve 34 is sleeved around the lever body 32. The sleeve 34 is used to loop around the part of the bottom hook 321 that hooks the top hook 263 and fix the two together. When the sleeve 34 moves upward along the hook-shaped tube 22 to its top and loop around the part of the bottom hook 321 that hooks the top hook 263, the elastic ring 323 abuts against the bottom edge of the sleeve 34 to position the sleeve 34 and prevent the sleeve 34 from sliding downward. The inner circumferential surface of the sleeve 34 has a receiving groove 341. When the user applies force to move the sleeve 34 downward, the elastic ring 323 will break through the bottom edge of the sleeve 34 and enter the receiving groove 341. The cooperation between the receiving groove 341 and the elastic ring 323 can limit the range of vertical movement of the sleeve 34 along the rod 32.

[0027] In addition to the preferred embodiment described above, the present invention provides a positioning structure for the lever element 30, including the rod body 32 and the sleeve 34. Alternatively, the sleeve 34 may be omitted, and a torsion spring may be provided between the rod body 32 and the pivot portion 14. This allows the rod body 32 to remain in a state where the bottom hook 321 is hooked onto the top hook 263 from the inside, thus closing the opening A. The opening A will only open when the rod body 32 is pushed inward by an external force. The structure of the lever element 30 is not limited to the two structures described above. As long as the bottom hook 321 of the rod body 32 can hook onto the top hook 263 from the inside when the lever element 30 closes the opening A, it is acceptable.

[0028] The above description is only a preferred embodiment of the present invention. Any equivalent changes made by applying the present invention specification and the claims should be included within the patent scope of the present invention.
