Description

A kind of lifting hook hook hand self-locking device

Technical field

The utility model belongs to lifting hook hook mobile phone structure technical field, especially relate to a kind of prevent torque arm car from transportation, torque arm filling hook hand and the lifting hook hook hand self-locking device that departs from of rubbish container shackle, the structural development of assembling system in particularly suitable torque arm.

Background technology

At present, the hook hand that the torque arm car of domestic use fills can not self-locking, likely breaks off relations and cause the accident when being subject to impacting in transportation.In order to anti-locking hook, at present general adopt the opening of hook hand to do smaller and opening are in hook heart position on the upper side, although play a role like this, cause to unload in case or hook case process hook hand and shackle departs from or hook hand to hook chain rate of rising to the bait more difficult.

Summary of the invention

The purpose of this utility model is the deficiency of this machine prior art and provides one to prevent torque arm car hook hand and rubbish container shackle in transportation from departing from, to unload in case or hook case process hook hand and shackle departs from or hook hand hooks that shackle is easy, structure simple lifting hook hook hand self-locking device.

The purpose of this utility model realizes like this, a kind of lifting hook hook hand self-locking device, be made up of hook hand, be characterized in, in the bearing hole of the coupler body of hook hand overthe openings, combination bearing is installed, block rotating shaft is arranged in combination bearing, the two ends of block rotating shaft are fixed with one piece of block otic placode respectively, and block clump weight is fixed on the other end of two pieces of block otic placodes, and hook hand both sides are respectively provided with an otic placode locating dowel pin.

Compared with the prior art the utility model has following distinguishing feature and good effect: the utility model is provided with combination bearing in the bearing hole of the coupler body of hook hand overthe openings, block rotating shaft is arranged in combination bearing, the two ends of block rotating shaft are fixed with one piece of block otic placode respectively, block clump weight is fixed on the other end of two pieces of block otic placodes, hook hand both sides are respectively provided with an otic placode locating dowel pin, drive block to rotate by block clump weight and realize the object that hook hand opening was closed or opened to block, when in hook arm, dress reaches and unloads case or hook case position, by the deadweight of block clump weight and the spacing of otic placode locating dowel pin, hook hand self-locking mechanism is opened, with reference to Fig. 3, be opened to hook hand opening maximum position, to depart from or hook hand hooks shackle and is more prone to because hook hand opening designs very hook hand and shackle, in hook arm, setting hook case puts in place, hook hand self-locking mechanism locking is made by the deadweight of block clump weight and the spacing of otic placode locating dowel pin, with reference to Fig. 4, block otic placode is hook hand opening base closed, when being subject to impacting, block otic placode Impact direction is greater than 0 degree, hook hand self-locking mechanism can not be opened automatically, ensure that in transportation or shackle when being subject to impacting of dumping rubbish can not depart from hook hand, when the utility model hook hand self-locking device is subject to impacting in transportation, hook hand can not depart from shackle, prevent because of the accident caused that breaks off relations, use benzene device, can be very large by the design of hook hand opening, to unload in case or hook case process hook hand and shackle departs from or hook hand hooks shackle and is more prone to.
