Detailed Description

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

According to one aspect of the invention, a rope end connector 1 is provided that can be used to connect a rope 1 to an object 3 from the middle of the rope. Referring to fig. 1, the rope end connector 1 includes a wedge pocket 11 and a wedge 12.

The wedge sleeve 11 has an inner cavity 111 with two open ends, and one end of the inner cavity 111 is large and the other end is small. Specifically, the inner cavity 111 has a large opening end 112 and a small opening end 113, and a wedge-shaped space is formed between the large opening end 112 and the small opening end 113. In some embodiments, the lumen 111 is flat when viewed from the large-mouth end 112 or the small-mouth end 113.

The wedge 12 has a large head end 121 and a small head end 122 opposite to the large head end 121, and the outer peripheral surface of the wedge 12 has a groove 123. The portion between the large end 121 and the small end 122 is wedge-shaped. In some embodiments, the wedge 12 is flat. In some embodiments, the large end 121 is rounded. The cross section of the groove 123 may be semicircular, V-shaped, trapezoidal, etc., but is not limited thereto.

The small end 122 of the wedge 12 is inserted into the cavity 111 from the large open end 112 of the cavity 111. Referring to fig. 2, the cable is folded in half from the middle of the cable, the folded portion passes through the cavity 111 from the small opening end 113 of the cavity 111, the folded portion is fitted over the wedge 12, specifically, the folded portion is wound in the groove 123 on the outer circumferential surface of the wedge 12 to prevent the cable from slipping off the wedge 12, and the cable is pulled from the small opening end 113 of the cavity 111 to insert the wedge 12 into the cavity 111. When the wedge sleeve 11 is subjected to a force opposite to the pulling force of the rope, the movement tendency of the wedge 12 is opposite to the movement tendency of the wedge sleeve 11 by the pulling of the rope, the rope wound around the outer circumference of the wedge 12 is squeezed between the inner wall of the inner cavity 111 and the wedge 12, and the more the force is, the more tightly the rope is squeezed. The width of the wedge 12 is larger than that of the small end 113 of the inner cavity 111 after the rope is wound on the outer periphery of the wedge 12, so that the wedge 12 and the rope are limited by the wedge-shaped inner wall of the inner cavity 111 and cannot be separated from the small end 113, and the wedge sleeve 11, the wedge 12 and the rope 2 are locked with each other. When the force on the wedge sleeve 11 is removed, the wedge 12 can be removed from the wedge sleeve 11 and the rope can be detached from the rope connection 1. The rope end connecting piece has the advantages that the rope can be connected from any position in the middle of the rope without cutting the rope, and the connecting position of the rope end connecting piece 1 on the rope can be adjusted randomly according to the requirement; the second has the self-locking characteristic.

One application mode of the hoisting structure is to directly hoist the object 3, the small opening end 113 is arranged upwards, the object 3 is connected below the wedge sleeve 11, the gravity of the object 3 can form a downward acting force on the wedge sleeve 3, so that the wedge sleeve 11, the wedge block 12 and the rope 2 are locked with each other, and the heavier the object 3 is, the larger the locking force is. Another application of the hoisting structure is to invert the hoisting structure of fig. 2, that is, the small end 113 is arranged downward, the object 3 is fixed, the other heavy objects to be hoisted are connected with the rope 2, the wedge sleeve 11, the wedge 12 and the rope 2 are locked with each other by using the gravity of the other heavy objects to be hoisted, and the heavier the other heavy objects to be hoisted, the larger the locking force is.

In one embodiment, the wedge sleeve 12 is connected to the object 3 by a pull rod 13, specifically, the pull rod 13 penetrates through the object 3, the elastic component 14 is located below the object 3, and the elastic component 14 plays a role of buffering when the object 3 is lifted. The buffer cushion 17 is disposed between the object 3 and the elastic member seat 15 at the upper end to prevent the object 3 from directly contacting the elastic member seat 15 to cause abrasion. The stop nut 16 is disposed below the lower elastic member seat 15 for restricting the pull rod 13 from being detached from the object 3. A cotter pin 19 is arranged below the limit nut 16 for preventing the limit nut 16 from falling off from the pull rod 13.

In one embodiment, referring to fig. 3, the rope 2 extending from the small opening end 113 of the inner cavity 111 passes through the rope clamp 4, the rope clamp 4 includes two clamping plates 41 arranged oppositely, the two clamping plates 41 are detachably connected, and the side edge of the clamping plate 41 has a rib 411.
