Abstract

The utility model discloses a spiral pin for with the cooperation of the connection shell in the spiral wire rope connector, including the spiral pin body, on the spiral pin body, the centre is dug and is equipped with the centre bore that runs through, evenly digs the rail groove that is equipped with a plurality of syntropy spirals on the surface, on the spiral pin body, still be equipped with a slant and the fluting of centre bore intercommunication along the centrum. The utility model discloses a spiral pin structure is ingenious set up the slant back of slotting along the centrum on the spiral pin body, during the use, this slant fluting can be to selling the wire rope face strand that external surface wire spiral coiled and holding power to have a fine cushioning effect toward interior extruded, so can protect the round pin body itself better, improve the holistic compressive capacity of spiral pin, moreover, because this slant slotted effect, the extrusion force that lets a thigh form can be utilized and form a power of holding tightly to the wire rope's of wearing to establish central hole central thigh, let wire rope can be fixed more firmly, therefore, the clothes hanger is strong in practicability.

Description

Screw pin

Technical Field

The utility model belongs to fastener production field especially relates to a be arranged in with spiral wire rope connector connect shell complex spiral round pin, and specially adapted harbour, pier, heavy and large-scale container hoist and mount are used in places such as loading and unloading transfer base.

Background

Along with the continuous development of economic trade, the freight volume of port wharfs and the like is larger and larger, the requirement on efficiency is higher and higher, the existing container hoisting is generally in a mode that a chicken heart ring with a circle of grooves around is spliced with a container hanging lug by a bolt and then hoisted, the end part of a load-bearing steel wire rope for hoisting is firstly wound by a circle around the grooves on the edge of the chicken heart ring and then is locked and fixed to be firmly fixed on the chicken heart ring, the process of winding the chicken heart ring wastes time and labor, and the risk of falling off is caused if the winding is not good, therefore, a closed spiral steel wire rope connector is developed by CN 207195560U and comprises a connecting shell and a spiral pin with conicity, when the connector is installed, the steel wire rope does not need to be bent, only six strands of the steel wire rope are separated according to the length of the spiral rail groove, and then the six strands are respectively accommodated in the six spiral rail grooves of the spiral pin, meanwhile, the central strand of the steel wire rope is also stuffed into the central hole of the spiral pin and is lightly pulled, because the spiral pin is externally designed into a spiral rail groove and a horn-shaped design with a big top and a small bottom, the contact stress line distance between the six strand surface strand steel wire ropes in the spiral rail groove and the inner wall of the steel wire rope pin hole is increased, the steel wire ropes are rapidly fixed under the action of stress and counter stress, the central strand is bound at the bottom of the steel wire rope pin hole under the extrusion of the six strand surface strand steel wire ropes and is stressed with other six strand surface strand steel wire ropes, and the steel wire rope is easily and conveniently installed. The device is also very convenient to detach, and can be completed by only prying the upper edge of the spiral pin by a small prying bar. However, the existing spiral pin has the risk of being extruded to be broken when the pressure is too high, and the tightness of the central strand is not enough.

SUMMERY OF THE UTILITY MODEL

To the technical problem mentioned above, the utility model provides a spiral round pin.

In order to achieve the technical purpose, the utility model adopts the following technical scheme:

the spiral pin is matched with a connecting shell in the spiral steel wire rope connector and comprises a spiral pin body, a through center hole is dug in the middle of the spiral pin body, a plurality of equidirectional spiral rail grooves are uniformly dug on the outer surface of the spiral pin body, and an inclined groove communicated with the center hole is further formed in the spiral pin body along the vertebral body.

Preferably, the spiral pin body is further provided with a plurality of reverse spiral track grooves, so that the spiral pin can be flexibly applied when the strand on the end of the steel wire rope to be connected is wound in the forward direction or in the reverse direction.

Preferably, a raised spiral thread is further arranged on the inner wall of the central hole and used for better holding the central strand of the steel wire rope to prevent slipping.

Due to the adoption of the technical scheme, the utility model discloses following technological effect has:

the utility model discloses a spiral pin structure is ingenious set up the slant back of slotting along the centrum on the spiral pin body, during the use, this slant fluting can be to selling the steel wire rope face strand that external surface steel wire spiral coiled and holding power to have a fine cushioning effect toward interior extruded, so can protect the round pin body itself better, improve the holistic compressive capacity of spiral pin, moreover, because this slant slotted effect, the extrusion force that lets a thigh form can be utilized and form a power of holding tightly to the steel wire rope's of wearing to establish central hole central thigh, let steel wire rope can be fixed more firmly, therefore, the clothes hanger is strong in practicability, and is worth promoting.
