[0028] The technical solutions in the embodiments of the present utility model will be clearly and completely described below in conjunction with the embodiments of the present utility model. Obviously, the described embodiments are only a part of the embodiments of the present utility model, rather than all of the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present utility model without making creative efforts fall within the scope of protection of the present utility model.

[0029] Embodiment 1

[0030] The preferred embodiment of the new round steel sling provided by the utility model is as follows Figures 1 to 5 As shown: A new round steel sling includes a connecting ring 10. Inside the connecting ring 10, a pressing component 1 is provided. One side of the bottom end of the connecting ring 10 is rotatably connected to a first connecting seat 2. One side of the first connecting seat 2 is hinged to a first hook 3. The other side of the bottom end of the connecting ring 10 is rotatably connected to a second connecting seat 9. One side of the second connecting seat 9 is rotatably connected to a second hook 8. One side of the first hook 3 and the second hook 8 is rotatably connected through a hinge shaft. The lower ends of one side of the first hook 3 and the second hook 8 are movably connected with a wear-resistant plate 7. Inside the first hook 3 and the second hook 8 on one side of the wear-resistant plate 7, an installation component 5 is provided.

[0031] The installation component 5 includes a card slot 502. The card slot 502 is opened at the lower end of the inner walls of the first hook 3 and the second hook 8. A reserved slot 506 is opened at the lower end of one side of the first hook 3 and the second hook 8. Inside the reserved slot 506, a fixing bolt 505 extending into the card slot 502 is movably connected. One side of the wear-resistant plate 7 is fixedly connected with a clamping block 501. A bolt hole 503 threadedly matched with the fixing bolt 505 is opened on one side of the clamping block 501. By using the clamping of the clamping block 501 inside the card slot 502 and then using the threaded cooperation between the fixing bolt 505 and the bolt hole 503, the quick disassembly and assembly action between the wear-resistant plate 7 and the first hook 3 or the second hook 8 can be realized, avoiding the excessive cost brought by replacing the entire first hook 3 or the second hook 8 in the traditional way, and the whole replacement process is simpler and more convenient.

[0032] In this embodiment, a clamping structure is formed between the clamping block 501 and the inside of the card slot 502. The cross-sectional shapes of the clamping block 501 and the card slot 502 are convex. By using the clamping of the convex clamping block 501 inside the card slot 502, the firmness of the initial clamping installation between the wear-resistant plate 7 and the first hook 3 or the second hook 8 is improved.

[0033] In this embodiment, one side of the surface of the fixing bolt 505 is fixedly connected with a rubber ring 504. The cross-sectional shape of the rubber ring 504 is O-shaped. By using the O-shaped rubber ring 504, after the fixing bolt 505 is tightened, the rubber ring 504 will be clamped against the inner wall of the reserved slot 506 and deformed, thereby avoiding the accidental loosening of the thread of the fixing bolt 505 and affecting the firm stability of the installation of the wear-resistant plate 7.

[0034] In this embodiment, the cross-sectional shape of the wear-resistant plate 7 is arc-shaped. One side of the wear-resistant plate 7 and one side of the clamping block 501 are integrally welded. By using the arc-shaped wear-resistant plate 7, it is convenient for the wear-resistant plate 7 to clamp and lift the round steel.

[0035] In this embodiment, anti-slip grooves 4 are equiangularly formed on the inner wall of the wear-resistant plate 7. The cross-sectional shape of the anti-slip groove 4 is an isosceles trapezoid. By using the isosceles trapezoid anti-slip grooves 4, the contact friction between the wear-resistant plate 7 and the surface of the round steel is increased, thereby improving the firmness of clamping the wear-resistant plate 7 to the surface of the round steel.

[0036] Embodiment 2

[0037] On the basis of Embodiment 1, a preferred embodiment of the novel round steel sling provided by the present utility model is as Figures 1 to 5 shown: The pressing component 1 includes a fixing groove 105 which is formed inside the connecting ring 10. A fixing spring 104 is fixedly connected to the inner bottom wall of the fixing groove 105. The top end of the fixing spring 104 is fixedly connected to a sliding plate 103. The top end of the sliding plate 103 is fixedly connected to a sliding rod 106 extending outside the fixing groove 105. The top end of the sliding rod 106 is fixedly connected to a fixing plate 107. The top end of the fixing plate 107 is fixedly connected to a rubber block 101. By using the elastic force of the fixing spring 104, the sliding plate 103, the sliding rod 106 and the fixing plate 107 are lifted, driving the top end of the rubber block 101 to closely adhere to and compress the bottom end of the lifting hook or the steel cable, thereby further avoiding the slippage between the lifting hook or the steel cable and the connecting ring 10 and ensuring the lifting stability of the round steel.

[0038] In this embodiment, a sliding structure is formed between the sliding plate 103 and the inside of the fixing groove 105. The top view shapes of the sliding plate 103 and the upper end of the fixing groove 105 are cross-shaped. By using the sliding of the cross-shaped sliding plate 103 and the inside of the fixing groove 105, the sliding rod 106 and the fixing plate 107 can only slide vertically up and down.

[0039] In this embodiment, a dial block 102 is fixedly connected to the front surface of the fixing plate 107. One end of the dial block 102 extends outside the connecting ring 10. By using the dial block 102, it is convenient for the user to drive the fixing plate 107 to slide downwards by the dial block 102.

[0040] Furthermore, a groove 11 is formed on the inner top wall of the connecting ring 10. The cross-sectional shape of the groove 11 is wavy. By using the wavy groove 11, the friction between the lifting hook or the steel cable and the inner top wall of the connecting ring 10 is increased, and the left and right sliding amplitude of the lifting hook or the steel cable on the inner top wall of the connecting ring 10 is reduced.

[0041] In addition, high-strength rubber sheets 6 are fixedly connected to the bottom ends of the first hook 3 and the second hook 8. The high-strength rubber sheets 6 are symmetrically distributed about the vertical central axis of the connecting ring 10. By using the high-strength rubber sheets 6, the flexible contact between the bottom ends of the first hook 3 and the second hook 8 and the ground is realized, and the anti-slip stability after the bottom ends of the first hook 3 and the second hook 8 are placed can be improved.

[0042] The working principle and use process of the utility model are as follows: first, the shifting block 102 is moved to drive the fixed plate 107 to slide down, and the sliding rod 106 and the sliding plate 103 are moved down to compress the fixed spring 104 to a suitable position, and then the lifting hook or steel cable is fixed to the inner top wall of the connecting ring 10, and the wavy groove 11 is used to increase the friction between the lifting hook or steel cable and the inner top wall of the connecting ring 10, and reduce the left and right sliding range of the lifting hook or steel cable on the inner top wall of the connecting ring 10, and then the shifting block 102 is released, and the elastic force of the fixed spring 104 is used to make the sliding plate 103, the sliding rod 106 and the fixed plate 107 rise, driving the top end of the rubber block 101 to press against the bottom end of the lifting hook or steel cable, thereby further avoiding the slippage between the lifting hook or steel cable and the connecting ring 10, and ensuring the lifting stability of the round steel;

[0043] Afterwards, the wear-resistant plate 7 can be driven by the first hook 3 and the second hook 8 to clamp and lift the round steel, and the isosceles trapezoidal anti-slip pattern 4 can be used to increase the contact friction between the wear-resistant plate 7 and the surface of the round steel, thereby improving the firmness of the wear-resistant plate 7 clamping the round steel surface. At the same time, when the wear-resistant plate 7 is severely worn and needs to be replaced, the fixing bolt 505 can be rotated until it is completely disengaged from the inside of the bolt hole 503, and then the wear-resistant plate 7 is pushed hard to make the clamping block 501 completely slide out of the inside of the clamping groove 502, so as to realize the disassembly of the wear-resistant plate 7, which is convenient for maintenance or direct replacement of the wear-resistant plate 7. During installation, the clamping block 501 is clamped into the clamping groove 50 2, and then insert the fixing bolt 505 into the reserved groove 506 and tighten it into the bolt hole 503, so that the clamping block 501 is firmly engaged with the inside of the clamping groove 502, thereby realizing the rapid disassembly and assembly action between the wear-resistant plate 7 and the first hook 3 or the second hook 8, avoiding the high cost caused by the traditional need to replace the entire first hook 3 or the second hook 8, and the whole replacement process is simpler and more convenient. At the same time, after the fixing bolt 505 is tightened, the rubber ring 504 will be stuck to the inner wall of the reserved groove 506 and deformed, thereby preventing the fixing bolt 505 from accidentally loosening the thread and affecting the firmness and stability of the installation of the wear-resistant plate 7.

[0044] The above are only preferred embodiments of the present invention and are not intended to limit the present invention. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
