Gravity self-locking hook structure

Abstract

The invention provides a gravity self-locking hook structure, which includes a connecting seat and a hooking body, wherein one side of the base of the connecting seat is provided with a positioning part combined with a plate body, and the other side of the base is provided with a positioning part. A pivot joint is provided at the side, and a recess is provided adjacent to the base above the pivot joint, and the hooking body has a junction pivotally connected to the pivot joint, and a pushing part is provided on one side of the junction , and the other side of the pushing part is bent upwards and extended with a hook part. When the lifting rope of the hooked body is inserted into the hooked body, the hooked body will be pulled down by the hooked body due to its own weight. The pushing part of the body, so that the lifting rope slides and moves to the concave part of the connecting seat to be hooked and positioned, and because the center of gravity of the hooked body is misaligned with the axis of the connecting seat, it can be linked to the hook part through the pushing part Take the pivot joint as the axis to rotate and displace towards the plate body to lock itself, so as to effectively prevent the lifting rope from falling out of the hooking body due to the impact of vibration during the traveling of the car body, causing the hooked body to fall and be damaged. .

Description

technical field [0001] The invention provides a gravity self-locking hook structure, in particular, a hooking body is pivotally connected to the connecting seat, and a hooking body is provided on one side of the hooking body to be pulled by a lifting rope of the hooked body to make the lifting rope slide and displace The push part is hooked and positioned at the concave part on the connecting seat, and the other side of the hook body is provided with a hook part that can be locked by the push part in conjunction with the pivot part as the axis of rotation and displacement. Background technique [0002] The living standards in today's society are constantly improving, making the quality requirements of clothing, food, housing, transportation and entertainment in daily life more and more high, and the practicality is getting better and better. In terms of transportation, in addition to In addition to locomotives with speed and flexibility, various cars are also becoming more a...

[0005] However, although the existing hook locking device A can use the hook-shaped body A21 to achieve the purpose of being firmly hooked on the article and not easy to fall out, the locking component A3 and the locked component A2 are misaligned by using the main switch lock. Only when the locked state of the hook body A21 can be released, the overall operation will still be subject to certain restrictions, and it will not be convenient for the user to manually operate, and because the base A1 and the car body use screws (not shown in the figure) The locking method is more cumbersome and inconvenient to assemble. In addition, the base A1, the locked component A2 and the locked component A3 are many and complicated, so that the assembly operation is quite time-consuming and costly, and it is not conducive to mass production. , which is the direction that people in this industry want to study and improve
