The cross section of the welding groove is V-shaped, so that the welding liquid accumulates in the middle, further strengthening the connection strength of the two stoppers.

[0015] In the above-mentioned gourd hook assembly, the block is trapezoidal, and the width of the block gradually increases from the block to the other block. The above-mentioned design can enhance the structural strength of the block itself and enhance the load-bearing and pressure-resistant effect.

[0016] Compared with the prior art, the hoist hook assembly has the following advantages:

[0017] 1. The hook connecting rod is arranged to pass through the through hole, and the outer diameter of the retaining ring above the stopper is larger than the aperture of the through hole, so that the stopper can always limit the downward movement distance of the hook to prevent the hook from falling when the screw falls off, effectively reducing safety hazards and enhancing the safety of the hook assembly.

[0018] 2. The stopper and the support plate are set as an integrated structure, which greatly enhances the connection strength between the two, increases the load-bearing and pressure-resistant capacity of the stopper, and better limits the falling of the hook, thereby further enhancing the safety of the hook assembly.

[0019] 3. The two blocks are welded and fixed to form a whole, which not only strengthens the connection strength of the two support plates, but also makes the blocks more stably support the hook upward, further enhancing the safety of the hook assembly. BRIEF DESCRIPTION OF THE DRAWINGS

[0024] The following are specific embodiments of the present invention and the accompanying drawings to further describe the technical solution of the present invention, but the present invention is not limited to these embodiments.

[0025] like Figure 1 and Figure 2As shown, the hoist hook assembly includes a hook 1 and two left-right symmetrical support plates 2. A guide wheel 3 is rotatably arranged between the upper ends of the two support plates 2, and the middle parts of the two support plates 2 are fixedly connected by horizontally arranged studs 4. The hook 1 is an integrated structure, and the hook 1 includes a hook body 1a and a connecting rod 1b, and the connecting rod 1b is vertically arranged between the lower ends of the two support plates 2.

[0026] Specifically,

[0027] The guide wheel 3 is installed as follows: a rotating shaft 5 is horizontally arranged between the two support plates 2, the axis of the rotating shaft 5 extends left and right, and the two ends of the rotating shaft 5 are respectively fixed to the two support plates 2. The guide wheel 3 is sleeved on the rotating shaft 5, and the two ends of the guide wheel 3 are respectively in contact with the two support plates 2, so that the guide wheel 3 rotates stably.

[0028] The stud 4 is installed as follows: the axis of the stud 4 extends left and right, and a clearance hole is horizontally penetrated on the support plate 2, which is arranged opposite to the stud 4. The two ends of the stud 4 pass through the two clearance holes respectively, and nuts 6 are screwed on both ends of the stud 4, and the nuts 6 are pressed tightly against the outer side of the corresponding support plate 2; two annular limiting surfaces are formed in the middle of the stud 4, and the two annular limiting surfaces are pressed tightly against the inner side of the two support plates 2 respectively, so as to stably fix the two support plates 2 together. In the actual product, there are two studs 4 and they are arranged in parallel front and back. At this time, there are four clearance holes and nuts 6 and they are arranged corresponding to the two studs 4 respectively, so as to strengthen the connection strength of the two support plates 2.

[0029] like Figures 1 to 3 As shown, a stopper 2a is integrally formed on the inner side of the lower end of the support plate 2, and the two stoppers 2a are located between the two support plates 2, and the two stoppers 2a are also symmetrically arranged. The two stoppers 2a are attached together and a through hole 7 is formed between the two of them in a vertically penetrating manner. The upper end of the connecting rod 1b passes through the through hole 7, and a retaining ring 1c is integrally formed on the outer wall of the upper end of the connecting rod 1b. The retaining ring 1c is coaxially arranged with the connecting rod 1b, and the outer diameter of the retaining ring 1c is larger than the aperture of the through hole 7. The retaining ring 1c is pressed on the two stoppers 2a at the same time, and the two stoppers 2a are fixedly connected to the retaining ring 1c by vertically arranged screws 8.

[0030] The connecting rod 1b of the hook 1 is arranged to pass through the through hole 7, and the outer diameter of the retaining ring 1c above the stopper 2a is larger than the aperture of the through hole 7, so that the stopper 2a can always limit the downward movement distance of the hook 1 to prevent the hook 1 from falling when the screw 8 falls off, thereby effectively reducing safety hazards and enhancing the safety of the hook 1 assembly.

[0031] At the same time, the block 2a and the support plate 2 are arranged as an integrated structure, which greatly enhances the connection strength between the two, increases the load-bearing and pressure-resistant capacity of the block 2a, and better limits the falling of the hook 1, thereby further enhancing the safety of the hook 1 assembly.

[0032] in,

[0033] The through hole 7 is formed as follows: half holes are vertically penetrated on the adjacent side walls of the two stoppers 2a, and the through hole 7 is formed between the two half holes. Preferably, the through hole 7 is a circular hole, and in this case, the half hole is a semicircular hole.

[0034] The screw 8 is installed as follows: at least two mounting holes 1d are axially penetrated on the retaining ring 1c, the number of mounting holes 1d is an even number and is evenly distributed along the circumference of the retaining ring 1c, and threaded holes are vertically opened on the two blockers 2a. The rod of the screw 8 passes through one of the mounting holes 1d and is screwed into the corresponding threaded hole, and the head of the screw 8 is tightly pressed on the top surface of the retaining ring 1c. The head of the screw 8 is set upward for installation. Preferably, the number of mounting holes 1d is at least 4, so that by setting a large number of mounting holes 1d, the hook 1 has different installation angles, adapts to different working conditions, and has good practicality.

[0035] Further explanation, such as Figure 1 and Figure 3 As shown, the two blocks 2a are fixed together, preferably welded together to form a whole, which not only strengthens the connection strength of the two support plates 2, but also makes the block 2a more stably support the hook 1 upward, further strengthening the safety of the hook 1 assembly. Specifically, welding grooves 9 are formed between the front side surfaces of the two blocks 2a and between the rear side surfaces of the two blocks 2a, and the through hole 7 is between the two welding grooves 9; the welding groove 9 is in the shape of a long strip and is vertically penetrated. The welding groove 9 is used to evenly fill the welding liquid to strengthen the connection strength of the two blocks 2a.

[0036] Furthermore, the front and rear side surfaces of the stopper 2a are transitionally connected to the end surface of the stopper 2a away from the corresponding support plate 2 through the inclined surface 2b, and the above-mentioned welding groove 9 is formed between two adjacent inclined surfaces 2b, and the cross section of the welding groove 9 is V-shaped. The cross section of the welding groove 9 is V-shaped, so that the welding liquid accumulates in the middle, further strengthening the connection strength of the two stoppers 2a.

[0037] In actual products, the block 2a is trapezoidal, and the width of the block 2a gradually increases from the block 2a to the other block 2a, so as to enhance the structural strength of the block 2a itself and enhance the load-bearing and pressure-resistant effects.

[0038] The specific embodiments described herein are merely examples of the spirit of the present invention. Those skilled in the art may make various modifications or additions to the specific embodiments described or replace them in similar ways, but they will not deviate from the spirit of the present invention or exceed the scope defined by the appended claims.
