Description

Technical Field

[0001] This utility model relates to the field of rope protection sleeves, and in particular to a rope protection sleeve that prevents rope slippage. Background Technology

[0002] Rope protectors, also known as heart-shaped loops, are rope protection structural components that prevent rope wear and breakage, thus ensuring safe use. They are typically used in two ways: one is to nest them inside a rope loop and lock them in place, using them as a hanging loop; the other, more widely used method, involves nesting them into sharp edges using their lower opening, utilizing their grooves as a passageway for rope movement, thereby protecting the rope.

[0003] However, existing rope protection sleeves typically have open top grooves. When used as rope protectors with sharp edges, especially in situations involving rope swaying during deployment or retraction, the rope can easily slip out of the groove, potentially causing serious accidents. This is particularly problematic when using rope protection sleeves to protect heavy loads on steel ropes, where winches are commonly used for traction, making rope swaying almost inevitable. Therefore, safety during use is difficult to guarantee. Currently, there is no corresponding solution to this problem. Utility Model Content

[0004] The purpose of this utility model is to overcome the shortcomings of the existing technology and provide a rope protection sleeve that is simple in structure, quick to assemble, and can protect the rope from coming out of the rope groove during use.

[0005] The equipment includes a rope protection sleeve body, which includes a curved transition section at the top and a clamping arm section integrally connected to the lower edge of the curved transition section and set downwards.

[0006] Above the curved transition section, an assembly base plate is integrally connected to its two wings. The assembly base plate has mounting holes arranged opposite each other, and locking connectors are inserted into the two mounting holes.

[0007] The effect achieved is that the main body of the rope protection sleeve uses its two clamping arm sections to nest in relatively sharp edges such as the side of a boat. The inner groove of the curved transition section set at the top is the rope groove. The steel rope or other pulling rope is embedded in the rope groove and locked on the mounting base plate using locking connectors to achieve locking to prevent the rope from coming out, thus realizing the anti-rope slippage function.

[0008] The beneficial effects of this utility model are: it solves the problem of easy rope detachment in existing rope protective sleeves, and is especially suitable for use as a protective structural component to prevent rope wear when mounted on sharp edges. Furthermore, the device has a simple structure, low cost, and quick assembly. Attached Figure Description

[0015] The realization of the purpose, functional features and advantages of this utility model will be further explained in conjunction with the embodiments and with reference to the accompanying drawings. Detailed Implementation

[0016] Reference Figure 1 , Figure 2 , Figure 3 and Figure 4 The present invention provides a rope protection sleeve for preventing rope slippage, which includes a rope protection sleeve body. The rope protection sleeve body includes a curved transition section 1 set at the upper part and a clamping arm section 2 integrally connected to the lower edge of the curved transition section 1 and set downward.

[0017] On the upper part of the curved transition section 1, an assembly base plate 3 is integrally connected to its two wings. The assembly base plate 3 has mounting holes 31 arranged opposite to each other, and a locking connector 4 is inserted into the two mounting holes 31.

[0018] The effect achieved is that the main body of the rope protection sleeve uses its two clamping arm sections 2 to nest in relatively sharp edges such as the side of a boat. The inner groove of the curved transition section 1 set at the top is the rope groove. The steel rope or other material pulling rope is embedded in the rope groove and locked on the mounting base plate 3 by the locking connector 4 to achieve locking to prevent the rope from coming out, thus realizing the anti-rope slippage function.

[0019] In Example 1, the assembly substrate 3 is a rectangular plate with smooth corner transitions.

[0020] The purpose of this is to ensure safe use and prevent injury.

[0021] Example 2, refer to the accompanying drawings in the specification. Figure 2The locking connector 4 consists of a screw 41 and a screw sleeve 42; the screw 41 passes through two mounting holes 31 on the two mounting base plates 3 in sequence, and is locked at its tail end by the screw sleeve 42.

[0022] This achieves the effect of forming a stable, closed rope groove, ensuring safe use.

[0023] Example 3, refer to the accompanying drawings in the specification. Figure 3 and Figure 4 The assembly hole 31 is in the form of a keyhole, including a circular channel and a rectangular channel disposed on the upper part of the circular channel and communicating with the circular empty sleeve.

[0024] The locking connector 4 is provided corresponding to the assembly hole 31 and includes a limiting block 43, a round rod 44 and a locking block 45; the limiting block 43 is provided with a round rod 44 in front of it, and a locking block 45 is integrally connected to the end of the round rod 44; that is, the round rod 44 and the locking block 45 are provided to fit the assembly hole 31.

[0025] The effect achieved is that the locking connector 4 passes through the mounting holes 31 on the two mounting base plates 3 in sequence, and after the locking block 45 passes through the second mounting hole 31, it is twisted downwards to achieve the limit of the upper part of the rope groove. That is, it achieves quick assembly and limit of the rope.

[0026] The foregoing has shown and described the basic principles, main features, and advantages of this utility model. It will be apparent to those skilled in the art that this utility model is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or basic characteristics of this utility model.
