SUMMERY OF THE UTILITY MODEL
The utility model aims at providing a fixed for hoist microspur unhook device through the structure that changes the lifting hook, makes its product just can remove the lifting hook after the microspur removes, accomplishes the unhook of product, and is fast, convenient to use, and the structural change is little, can promote in each field.
In order to solve the above problem, the utility model provides a pair of microspur unhooking device for fixed hoist has adopted following technical scheme:
a micro-distance unhooking device for fixing a lifting appliance comprises a lifting hook, a movable handle and a rotating main shaft; the lifting hook is positioned on the rotating main shaft, is connected with the rotating main shaft and freely rotates around the rotating main shaft; the movable handle is positioned on one side of the lifting hook and is fixedly connected with the lifting hook;
the lifting hook comprises a hanging body and a hook body, the hanging body is positioned on the rotating main shaft and is connected with the rotating main shaft, and the hanging body extends and is distributed along the central line of the section of the rotating main shaft; the hook body is positioned at one end of the hanging body and fixedly connected with the hanging body, a bearing cambered surface is arranged on the hook body, and the center of the bearing cambered surface is the same as the center of the section of the rotating main shaft.
Furthermore, the hanging body is provided with a connecting cambered surface, the connecting cambered surface is positioned on one side of the hanging body and extends to the hook body from one side of the rotating main shaft, one end of the connecting cambered surface is connected with the bearing cambered surface in an arc mode, and the other end of the connecting cambered surface is connected with one side of the hanging body.
Furthermore, the connecting cambered surface is distributed in an arc line, and the width of the hanging body at one side close to the rotating main shaft is larger than that at one side close to the hook body.
Furthermore, the connecting arc surface and the bearing arc surface are connected through a connecting arc, and the size of the connecting arc corresponds to the size of the excircle of a product to be used.
Furthermore, the length dimension of the hook body is larger than half of the length dimension of the hanging body.
Furthermore, the bearing arc surface is in an arc shape, and the center of the arc is superposed with the center of the section of the rotating main shaft.
The beneficial effects of the utility model reside in that: the utility model provides a pair of microspur unhooking device for fixed hoist, cross-section center through bearing cambered surface and rotatory main shaft coincides mutually, consequently remove the back at the product microspur, will hang the body through removing the handle and rotate, it is rotatory equally to follow the body that hangs to bear the cambered surface this moment, because central coincidence, so on the pitch arc route that is in original position all the time at rotatory in-process, can not interfere the product, in case leave the product and just can lift the product off, only need slight distance to remove alright completion, simple structure is suitable for the popularization itself, the coupler that increases can further guarantee safety.
