Description

Technical Field

[0001] This utility model relates to the field of rope sling technology, specifically to a high-safety snap-on rope sling. Background Technology

[0002] Rope slings are rope-like tools made of materials such as fiber and metal, mainly used for connecting, towing, or securing objects. They are widely used in maritime industrial transportation and outdoor fields. Based on material, they can be divided into fiber rope slings and metal rope slings. Fiber rope slings are lightweight and corrosion-resistant, suitable for light-duty operations; metal rope slings have high strength and load-bearing capacity, and are mostly used for heavy-duty towing, such as crane lifting and ship mooring.

[0003] Current methods of connecting rope harnesses still have significant limitations: either the rope harnesses are directly tied together, or they are spliced ​​using safety buckles. However, neither of these methods can meet the needs of flexible operation. The knots are often tight and stiff, which not only makes them prone to localized wear under stress due to the fixed angle, but also makes daily adjustments or disassembly time-consuming and laborious, especially in emergencies where they are difficult to untie quickly. While safety buckles are easier to operate than knots, their structural design limits the range of motion after connection, and when the rope harness needs to swing at multiple angles, the connection often gets stuck or pulled. Utility Model Content

[0004] To solve the above-mentioned problems, this utility model proposes a high-safety snap-on rope catch that is easy to open at the rope catch connection and has high flexibility.

[0005] To solve the above-mentioned technical problems, the technical solution proposed by this utility model is: a high-security snap-on rope catch, comprising:

[0006] The connecting buckle has a connecting hole one and a connecting hole two in the middle, and a movable opening on one side that communicates with the connecting hole one. A stop block is hinged in the movable opening, and the stop block is fixed to the connecting buckle by bolts.

[0007] A connecting ring 1 is located on one side of the connecting buckle, passing through a connecting hole 1, and a rope loop 1 passing through its inner side is connected to it;

[0008] A second connecting ring is located on the other side of the connecting buckle and is connected to the connecting buckle via a ring buckle. The ring buckle passes through both the second connecting hole and the inner side of the second connecting ring. A spring is connected between the side wall of the ring buckle and the inner wall of the second connecting hole. A second rope loop is connected to the second connecting ring and passes through its inner side.

[0009] Furthermore, the shape of the stop block matches the shape of the movable opening, and the contact surface between the stop block away from the hinge side and the movable opening is a mutually adaptable inclined surface.

[0010] Furthermore, both the stop block and the connecting buckle have protrusions extending outwards at their joints, and each protrusion has a threaded hole. The two threaded holes are coaxially aligned, and the bolt is threadedly connected to both threaded holes.

[0011] Furthermore, a limiting groove for a matching connecting ring is provided on the inner side wall of the connecting hole.

[0012] Furthermore, both connecting ring one and connecting ring two are metal rings, with a hard rubber covering the outside.

[0013] Compared with existing technologies, this invention has the following advantages: The connection point is secured with a bolt-fixed stop; simply loosening the bolt opens the movable opening, making operation simple and quick, requiring no complex tools and significantly improving ease of opening. One side's connecting ring engages with a buckle via a limiting groove, restricting excessive swaying while allowing for some movement. The other side's connecting ring is connected to a buckle via a ring buckle, and the spring structure between the ring buckle and the buckle buffers the force, allowing the connection point to rotate flexibly within a certain range. The hard rubber coating on the outside of the metal ring ensures load-bearing capacity while reducing rigid friction, allowing the rope to adjust its angle more naturally under stress, balancing safety and ease of use.

[0019] The present invention will now be described in further detail with reference to the accompanying drawings.

[0020] Combined with appendix Figure 1 Appendix Figure 2A high-safety buckle-type rope catch includes: a connecting buckle 1, with a connecting hole 2 and a connecting hole 3 in the middle, and a movable opening communicating with the connecting hole 2 on one side. A stop block 4 is hinged in the movable opening. The shape of the stop block 4 matches the shape of the movable opening, and the contact surface between the stop block 4 and the movable opening on the side away from the hinge is a mutually adaptable inclined surface, which can tightly fit the movable opening, reduce gaps, and improve the connection sealing and stability. The inclined surface can restrict the movement direction of the stop block 4.

[0021] Combined with appendix Figure 1 Appendix Figure 2 Appendix Figure 4 The stop block 4 and the connecting buckle 1 are connected and fixed by bolts 5. The stop block 4 and the connecting buckle 1 are provided with protrusions 12 extending outward at the joint. The protrusions 12 are provided with threaded holes. The two threaded holes are coaxially aligned. The bolts 5 are threadedly connected in the two threaded holes at the same time, making the connection more secure and reliable and reducing the risk of the stop block loosening.

[0022] Combined with appendix Figure 2 A connecting ring 6 passes through a connecting hole 2 and is located on one side of the connecting buckle 1. A rope loop 7 passes through its inner side and is connected to it. A limiting groove matching the connecting ring 6 is provided on the inner wall of the connecting hole 2, which can limit the displacement and sway of the connecting ring 6 and enhance the overall structural stability.

[0023] Combined with appendix Figure 2 Appendix Figure 3 A second connecting ring 8 is located on the other side of the connecting buckle 1 and is connected to the connecting buckle 1 via a ring buckle 9. The ring buckle 9 passes through both the second connecting hole 3 and the inner side of the second connecting ring 8. A spring 10 is connected between the side wall of the ring buckle 9 and the inner wall of the second connecting hole 3. A second rope 11 is connected to the second connecting ring 8 and passes through its inner side. Both the first connecting ring 6 and the second connecting ring 8 are metal rings, with a hard rubber covering on the outside, which retains the high strength and load-bearing capacity of the metal while using the rubber for cushioning, shock absorption, and to prevent wear on the rope 11.

[0024] The specific implementation of this utility model is as follows: When using the snap-on rope catch, first unscrew the bolt 5 from the protrusion 12 of the connecting snap-on 1 and the stop 4, and flip the stop 4 outward to open the movable opening. Pass the connecting ring 6 through the connecting hole 2, so that it is snapped into the inner limiting groove, and then pass the rope catch 7 through the inner side of the connecting ring 6 and fix it. Then close the stop 4, use the inclined surface to tightly fit the movable opening, and screw the bolt 5 back into the two coaxial threaded holes to complete the fixation. Next, pass the rope catch 11 through the inner side of the connecting ring 8 and fix it. During use, the connecting ring 6 moves in the limiting groove, and the connecting ring 8 is buffered by the ring buckle 9 and the spring 10 and rotates flexibly. The hard rubber on the outside of the metal ring reduces the wear of the rope catch. When it needs to be disassembled, simply loosen the bolt 5 again to open the connecting snap-on 1.
