Embodiment
Below in conjunction with the accompanying drawing in the utility model embodiment, be clearly and completely described the technical scheme in the utility model embodiment, obviously, described embodiment is only the utility model part embodiment, instead of whole embodiments.Based on the embodiment in the utility model, those of ordinary skill in the art are not paying the every other embodiment obtained under creative work prerequisite, all belong to the scope of the utility model protection.
The rope releaser of the fall arrest of lifting means shown in Fig. 1-4 test, comprises boatswain chair 1, lower boatswain chair 2, pin plate 3 and web joint 7;
The upper end of described upper boatswain chair 1 is provided with lifting hole(eyelet) 4, and the lower end of described lower boatswain chair 2 is provided with lower lifting hole(eyelet) 5, and the lower end of described upper boatswain chair 1 is connected by embedded structure with the upper end of upper boatswain chair 1;
Described embedded structure is specially: the side of the bottom of boatswain chair 1 arranges a kerf 8 on described, the top of otch 8 slopes down to otch 8 bottom to turning back after opposite side extends one section, arranges an abaculus 9 consistent with otch 8 shape size in the upper end of described lower boatswain chair 2 and otch 8 corresponding position on upper boatswain chair 1;
During pulling force by vertical direction after the abaculus 9 of described lower boatswain chair 2 is chimeric with the otch 8 of upper boatswain chair 1, the otch 8 of described upper boatswain chair 1 and the abaculus 9 of lower boatswain chair 2 realize moving in opposite directions of horizontal direction and vertical direction along contacting inclined-plane simultaneously;
Described web joint 7 is two pieces, and symmetry is fixedly installed on the both sides, upper end of lower boatswain chair 2, is covered by embedded structure;
