Description
Technical Field
The utility model relates to a tower machine round pin axle technical field, more specifically says, it relates to a round pin axle rotational lock.
Background
At present, a tower crane upper support and a rotary tower body are generally connected through a pin shaft, split pins or vertical pins are generally inserted into two ends of the pin shaft after the pin shaft is driven into a pin shaft hole, the pin shaft is loosened along with the change of load in a fixing mode, the fixing effect of the pin shaft is influenced, and even the pin shaft falls off to cause safety accidents.
Therefore, a new technical solution is needed to solve the above problems.
SUMMERY OF THE UTILITY MODEL
To the deficiency that prior art exists, the utility model aims to provide a round pin axle rotational lock.
In order to achieve the above purpose, the utility model provides a following technical scheme: the utility model provides a round pin axle rotational lock, includes round pin axle and fixed block, the round pin axle is towards the tip fixedly connected with locating lever of fixed block, the fixed block is offered towards the surface of locating lever and is supplied locating lever male constant head tank, the logical groove of vertical and running through its lateral wall is seted up to the locating lever, lead to the inslot sliding connection and have two gag lever posts, fixedly connected with spring between the tip between two locating levers, supply locating lever male constant head tank has been seted up to the inner wall of constant head tank, the locating lever stretch out logical tip with the tip inner wall of constant head tank is parallel inclined plane, the lateral wall fixedly connected with connecting plate of fixed block, threaded hole and threaded connection have the.
Through adopting above-mentioned technical scheme, when installing again, install the fixed block in the workpiece surface that needs fixed through the connecting plate now, insert the round pin shaft hole with the locating lever end of round pin axle again, the locating lever inserts in the constant head tank, under the effect on inclined plane, two gag lever posts stretch into logical inslot portion, make the spring compressed, when the locating lever inserts the constant head tank completely, under the effect of the elasticity of spring, the tip of gag lever post enters into the spacing inslot, thereby fix the round pin axle, with the stability of guaranteeing the workpiece setting.
The utility model discloses further set up to: the cross sections of the positioning rod and the positioning groove are rectangular.
Through adopting above-mentioned technical scheme, can further prevent that the round pin axle from taking place to rotate, further guarantee the stability of round pin axle to guarantee the stability to the work piece installation.
