Utility model content
In order to solve safety belt under prior art due to wind-force, gravity, the impact of the factors such as manpower rocks, and safety belt one end is fixed, make safety belt that the phenomenon of local rotation occur, finally cause the safety belt locked problem of tiing a knot, the utility model provides a kind of novel can prevent the hook that safety belt tangled up and knotted is locked, by its structural design, make safety belt at wind-force, gravity, under the impact of the factors such as manpower rocks, can entirety together rotate freely, can there is not the knotting deadlock phenomenon that local rotation causes, concrete structure of the present utility model is as described below:
Prevent the hook that safety belt tangled up and knotted is locked, comprise the hanger bulk of U font, it is characterized in that:
The hanger bulk of described U font, its upper, open end place is provided with a plate, and the length of this connecting plate equals the width of the upper, open end of hanger bulk, and the two ends of this connecting plate are welded on the upper, open end of hanger bulk;
Described connecting plate in the middle position offers a connecting through hole, is provided with a rotatable safety belt coupling assembling at this connecting through hole place.
According to a kind of hook that prevents that safety belt tangled up and knotted is locked of the present utility model, it is characterized in that, described safety belt coupling assembling comprises safety belt connecting rod, anti-falling limit post, safety belt connecting ring, wherein, safety belt connecting rod is a column type bar, its bar footpath is less than the aperture 1～2mm of the connecting through hole of offering at connecting plate middle part, the length of safety belt connecting rod will grow 1～2mm than the degree of depth of connecting through hole, be provided with an anti-falling limit post in the welding of the lower end of safety belt connecting rod, and the post footpath of this anti-falling limit post is greater than the aperture 10～15mm of connecting through hole, the upper end of safety belt connecting rod is fixedly connected with and is provided with a safety belt connecting ring.
According to a kind of hook that prevents that safety belt tangled up and knotted is locked of the present utility model, it is characterized in that, described safety belt connecting ring is divided into connecting ring body and connecting ring base two parts, connecting ring body is fixedly installed on the top of connecting ring base, the bottom of connecting ring base is fixedly connected with safety belt connecting rod, and the width of connecting ring base is greater than the bar footpath 20～30mm of safety belt connecting rod.
Purpose of design is herein, because the diameter of the safety belt connecting rod 3a of safety belt coupling assembling 3 is less than the diameter of the connecting through hole 2a offering at connecting plate 2 middle parts, make safety belt connecting rod insert after this connecting through hole and can in this through hole, rotate, the hanger bulk 1 that makes to be connected up and down with it and safety belt connecting ring 3c each other also can independent rotation, can there is not the knotting deadlock phenomenon fixedly causing due to safety belt one end, the connecting through hole that the anti-falling limit post 3b arranging and connecting ring base 3c2 make whole safety belt coupling assembling can not offer from the middle part of connecting plate skids off up and down, safety belt coupling assembling is closely connected with hanger bulk.
Use and of the present utility modelly a kind ofly prevent that the locked hook of safety belt tangled up and knotted from having obtained following beneficial effect:
1. a kind of hook that prevents that safety belt tangled up and knotted is locked of the present utility model, it is simple in structure, reasonable in design, and connected safety belt can synchronous rotary, and the safety belt knotting deadlock phenomenon that local rotation causes because one end fixes can not occur;
