Embodiment
Embodiment 1:
In order to overcome when installing, debugging or safeguard equipotential connection connection mechanism, housing can not navigate to problem fixed position being brought potential safety hazard to follow-up work and staff, the utility model provides a kind of wedging wheel locking device be arranged on equipotential connection connection mechanism as depicted in figs. 1 and 2, it is characterized in that: the block 11 comprising handle shaft 2, extension spring 3, wedging wheel shaft 4, wedging axle sleeve 5, wedging wheel 6, extension spring hanging scroll 7, extension spring set screw 8 and be arranged on equipotential link mechanism shell 10;
Described wedging axle sleeve 5 is fixed on the outside of the support 9 of equipotential connection connection mechanism, wedging wheel shaft 4 is through wedging axle sleeve 5 and support 9, described wedging wheel 6 is fixed on the inner of wedging wheel shaft 4, the outer end fixed handle axle 2 of described wedging wheel shaft 4, described wedging wheel 6 is fixed with extension spring set screw 8, described extension spring hanging scroll 7 is fixed on inside support 9, and described extension spring 3 one end is fixed on extension spring set screw 8, and the other end is fixed on extension spring hanging scroll 7.
When the housing 10 of equipotential connection connection mechanism needs fixing, handle with sleeve axle 2, extension spring 3 is in extended state, wedging wheel 6 can rotate to an angle centered by wedging wheel shaft 4, when the block 11 blocked on housing 10 6 one end is taken turns in wedging, the direction of wedging wheel 6 clamping is contrary with the pivotal direction of housing 10, thus plays locking and positioning effect, prevents housing 10 reversed turning of equipotential connection connection mechanism.And counter-rotation handle shaft 2, then can make the block 11 on wedging wheel 6 disengaging housings 10, thus housing 10 positive and negative direction is rotated freely.
This wedging wheel locking device be arranged on equipotential connection connection mechanism that the utility model provides can be good at equipotential link mechanism shell to navigate on certain fixed position needed, namely housing is allowed only to rotate in a direction, stop housing counterrotating simultaneously, thus enable the installation of equipotential connection connection mechanism, debugging or maintenance work more safe and reliable, further avoid dangerous generation.
Embodiment 2:
Present embodiments provide a kind of wedging wheel locking device be arranged on equipotential connection connection mechanism, it is characterized in that: the block 11 comprising handle shaft 2, extension spring 3, wedging wheel shaft 4, wedging axle sleeve 5, wedging wheel 6, extension spring hanging scroll 7, extension spring set screw 8 and be arranged on equipotential link mechanism shell 10.
