TH25708A - Screw jack - Google Patents

Abstract

The body will be built in a single set of aluminum resin or hard resin material. Which is attached on a base with a recess being created in its central area. The bottom surface of the leveled channel. Always with the surface touching the ground The large bevel gear is attached to the main threaded shaft that is placed. In the slit of the base through the support bearings The lower end of the main threaded shaft is attached to the bearing. The thrust is firmly thrust like a shaft to form the main thread upright, then the small bevel gear mounted on the shaft continues to operate on the bearing portion mounted on the combined housing. Is one set Which will be coupled with a large bevel gear Threaded part of the shaft made The main thread is attached to the threaded portion created on the inner side of the sheath. A threaded and threaded part is created on the outer circumference of the auxiliary sleeve. The threaded part is attached to the threaded portion of the inner sheath, where heavier objects are held. In its outer circumference with grooves protruding in the vertical direction And at the top of it too A metal supporting plate 10a is created on the outer sheath 10, formed by Flat plate bending and cylindrical forming And the connection opposite of it For example, the outer casing that fits in the groove of the inner sheath is raised to a heavier object to prevent rotation of the inner sheath. 9 The inner sheath is lifted upward, directed by the inner sheath. out For this reason the sleeve keeps the 8 threaded so that it can be raised upwards. So in this way, mom A threaded force has a structure that lifts the load object on the metal support.

1. A threaded jack consists of a base, a fluted body that is formed in place. That and fixed on the surface above the base A thrust bearing mounted on a section area The middle of the upper surface of the base A large flowery flower is placed on top of the base through it. Such a thrust bearing, for example, is the main threaded shaft of the bevel gear. Such a big Will be firmly fixed at its bottom end to the said support bearing And upright up from there, the small gear will continue to work on the body through the bearing and grinded with Such a large bevel gear The outer casing is guided along the fuselage grooves and The inner casing that lifts heavy objects is placed inside the outer casing and is guided by the The outer casing The main gear shaft is rotated through the large bevel gear by a small bevel gear, which is rotated by an external drive path so that a heavy object is lifted where the hull is. Was created together as one set. Cast aluminum or resin can be hardened. 2.The threaded jack includes an outer casing that is guided along the body and is made It is suitable to introduce the inner sheath that is lifting heavier objects where the lower sheath is formed by Bending the flat sheet into a cylindrical shape and the overlap and joining the surface. The opposite end of such a cylindrical plate For example, the outer casing is fitted into the groove formed in the vertical body so that the outer casing is prevented from rotation.
