A pressing hand assembly for a horizontal jack

Abstract

The invention discloses a pressing handle assembly for a horizontal lifting jack. An outer thread is arranged on the outer periphery of the end of a handle. An inner thread is arranged in a columnar cavity of a pressing handle body, and the handle is sleeved with a handle sleeve. During installation, the handle sleeve is arranged on the outside of a handhold part of the handle in a sleeving mode and fixed to the handle through a clamping grove and a protrusion. The handle is installed in the columnar cavity through matching of the inner thread and the outer thread, and the opening end of the handle sleeve is clamped between the handle and the columnar cavity. Fixation and disconnection of the handle and the pressing handle body can be achieved only by rotating the handle by several circles, and the handle sleeve does not fall off the handle in use. The pressing handle assembly for the horizontal lifting jack is simple in structure and reasonable in design, the fixation and disconnection of the handle and the pressing handle body can be achieved only by rotating the handle by several circles by an operator, and the handle can be easily fixed to or drawn out of the pressing handle body. The pressing handle assembly for the horizontal lifting jack is easy to operate, reasonable in structure, high in motion reliability, capable of guaranteeing use safety and meanwhile easy to machine and low in cost.

Description

technical field

[0001] The invention relates to the technical field of jacks, in particular to a pressing handle assembly for a horizontal jack. Background technique

[0002] The jack is mainly used in factories, mines, transportation and other departments as vehicle repair and other lifting, support and other work. At present, the common hydraulic horizontal jacks on the market mainly include a handle, a hand body and a hand screw. The handle is provided with a groove toward one end of the hand body in use. A thumb screw is installed on the above-mentioned snap handle body. When the jack is working, insert the handle into the jack in the middle of the snap handle shaft, and turn the snap screw into the groove of the handle, thereby locking the handle on the snap handle body; when the jack is not working , unscrew the thumb screw so that the thumb screw breaks away from the engagement with the groove, and at this moment the handle can be pulled out from the jack of the sna...
