Abstract
The technology provided by the invention aims to overcome the defects in the prior art and provide a draw hook with simple structure and capable of firm tensioning and rapid unhooking. The draw hook includes a U-shaped body with two supporting legs; one end of a rotating plate is in rotation connection with one leg of the U-shaped body; the other leg of the U-shaped body is provided with a groove; the other end of the rotating plate extends into the groove; a limiting block for limiting the rotating plate is in rotation connection in the groove; and when the limiting block rotates to a certain position, the other end of the rotating plate can be detached from the groove.
Description
Technical field
This technology relates to the annex of a kind of lifting, lifting gear, specifically a kind of simple in structure, and tension is reliable, and drag hook rapidly breaks off relations.
Background technology
At present, on market, sell and the kind of drag hook that uses a lot, there is not yet simple in structurely, both strained reliably, drag hook rapidly breaks off relations again.
Summary of the invention
The object of this technology is to overcome deficiency of the prior art, provides a kind of simple in structure, and it is firm both to have strained, and drag hook rapidly breaks off relations again.
The object of this technology is achieved by the following technical programs.
This drag hook, comprise the body that is u shape with two legs, an angle of one end of rotor plate and u shape body is rotatedly connected, another angle of u shape body has groove, the other end of rotor plate stretches in groove, in groove, be rotatably connected to rotor plate is carried out to spacing limiting stopper, when rotary spacing piece is when a certain position, the other end of rotor plate can depart from groove.
The beneficial effect of this technology: when use, hoisting rope hangs on rotor plate, when normality, due to spacing to rotor plate of limiting stopper, the rotor plate other end is in groove, and hoisting rope can not come off from rotor plate.Need to make fast hoisting rope come off (unhook) time, only need rotary spacing piece, make limiting stopper no longer spacing to rotor plate, rotor plate just swings and comes off in groove, the hoisting rope rotor plate that naturally just comes off.Rise and draw the rope of weight to pack into after turning block, reliably spacing by limiting stopper, rise and draw weight; To target location, limiting stopper rotates, and turning block departs from spacing, and rope breaks off relations rapidly.The drag hook of this technology, simple in structure, when work, tension reliably, is broken off relations rapidly again, effectively increases work efficiency.
Above-mentioned drag hook, described limiting stopper is eccentric wheel structure.
Above-mentioned drag hook, described limiting stopper is that a cross-sectional plane is non-circular cylinder.Preferably, it also comprises a handle being connected on cylinder, between handle and body, is provided with spring; Spring is in the time of normality, and cylinder carries out spacing state in rotor plate.
Accompanying drawing explanation
Fig. 1 is the front view of the drag hook of this technology;
Fig. 2 is the left view of drag hook.
The specific embodiment
Below in conjunction with accompanying drawing, describe structure and the working process of this technology in detail.
Drag hook shown in Figure 1, comprises the body that is u shape 1 with two legs 2,3, on an angle 3, has groove 4.The Yu Zhi angle, one end 1 of rotor plate 5 is rotatedly connected, and the other end of rotor plate stretches in groove.In groove, be rotatably connected to rotor plate is carried out to spacing limiting stopper 6, described limiting stopper is that a cross-sectional plane is non-circular cylinder.Handle 7 is connected on cylinder, is provided with spring 8 between handle and body; Spring is in the time of normality, and cylinder carries out spacing state in rotor plate.
When rotary spacing piece is when a certain position, limiting stopper 6 is no longer spacing to rotor plate, and rotor plate swings, and its other end can depart from groove, and the rope 10 that hangs weight 9 can come off from rotor plate.
