Description

Technical Field

[0001] The utility model relates to the technical field of steel wire ropes, in particular to a rope connector. Background Art

[0002] A wire rope connector is a tool or device used to connect or secure wire ropes, and is widely used in construction, transportation, and other areas that require lifting or pulling. Due to its importance, selecting and using the right wire rope connector is essential to ensure operational safety and efficiency.

[0003] The current push-type rope connector usually presses and clamps the wire rope through two connecting seats, and uses bolts to connect the two sets of connecting seats to increase the pressure. The clamping slot in the general rope connector is difficult to fully adapt to the diameter of the wire rope. Therefore, the push-type rope connector can only maintain pressing contact with the wire rope through the two sets of connecting seats, and the contact area is limited. The present solution provides a rope connector, which increases the clamping area of ​​the wire rope without increasing the difficulty of operation by adding a boosting structure between the existing two connecting seats. Utility Model Content

[0004] The utility model aims at least to solve the problem in the prior art that the existing push-type rope connector can only be subjected to connection pressures at two locations, the upper and the lower.

[0006] Preferred technical solution one: the extrusion and expansion mechanism includes two groups of pressure plates and an elastic telescopic rod fixedly connected between the two groups of pressure plates. The outer ends of the two groups of pressure plates are respectively inserted into the two groups of clamps and the inner walls are in sliding contact with the outer protrusions. As the clamps close, the two groups of outer protrusions approach each other and push the two groups of pressure plates away from each other.

[0007] Preferred technical solution 2: The front and rear ends of the external protrusion are fixed with limiting ribs, and the two ends of the pressure plate are clamped between the front and rear two groups of limiting ribs to limit the front and rear placement positions of the pressure plate.

[0008] Preferred technical solution three: The outer end of the pressure plate is an inwardly concave arc surface consistent with the shape of the steel wire rope.

[0009] Preferred technical solution four: A vertical groove is provided on the top seat or the base at the connection between the two groups of slots, and the outer protrusion slides in the vertical groove through a fixed slider to adjust the extension amount of the outer protrusion.

[0010] Preferred technical solution five: the threaded column rotatably mounted on the sliding block passes through the threaded hole opened on the vertical groove wall and extends to the outside of the top seat or the base.

[0011] The above structure enables this solution to have the following beneficial effects:

[0012] 1. On the basis of the existing structure, the contact area with the wire rope is increased from the left and right sides by adding an extrusion expansion mechanism;

[0013] 2. The extension of the extrusion expansion mechanism is achieved through the closed extrusion of the top seat and the top seat, which reduces the additional operation each time and makes the connection and disassembly of the wire rope extremely convenient;

[0014] 3. The movable setting of the external protrusion can further adapt to steel wire ropes of different diameters. BRIEF DESCRIPTION OF THE DRAWINGS
