2results about How to "Improve the pulling effect" patented technology

This utility model relates to a convenient electric motor assembly / disassembly tool, belonging to the field of electric motor assembly technology. The convenient electric motor assembly / disassembly tool includes: a base frame with two guide grooves at its lower end and a connecting frame fixedly connected to its upper end; a pull-out assembly / disassembly mechanism mounted on the surface of the connecting frame, the surface of which extends into the interior of the guide grooves; wherein, the pull-out assembly / disassembly mechanism includes a meshing component mounted inside the connecting frame; the pull-out assembly / disassembly mechanism provides good support for the motor during use, and the lower end of the crossbeam engages with the meshing buckle to properly position the bushing. Driving the meshing component can displace the motor, thereby achieving a good pull-out effect on the bushing during motor movement, ensuring the efficiency of electric motor assembly / disassembly.

The utility model relates to the field of building construction discloses a new type of anti -void pull -pressure support, including upper seat board, lower seat board, L type draw hook and pier top anchoring assembly, the upper seat board top center fixedly connected with the ceiling, both sides of upper seat board all are fixedly connected with the wing plate, the upper surface of upper seat board is equipped with the upper thread hole, the surface of upper thread hole is detachably installed with upper structure board through upper bolt, both sides of wing plate all are equipped with the limit slot, the lower surface of lower seat board is provided with two groups of longitudinal and transverse rib plate. In the utility model, through being provided with longitudinal and transverse rib plate inclined plane structure, effectively solve the grouting air retention problem, ensure that support and foundation are closely connected, improve structural stability, at the same time, the shear structure and the anti -pull structure have strengthened the ability of support resistance shear and tension respectively, make support still can work stably under the complex stress environment, promote building structure overall security.
