Problems solved by technology

[0005] Beneficial effects: the present invention adopts a double-stage transmission method to realize the low height of the screw, and adopts the method of a large flange and a small flange to cooperate with the screw screw to realize the high extension, so it effectively overcomes the existing single structure of the existing jack. The use height of the truck is low, which cannot meet the defect of using more space

Abstract

The invention discloses a structure of a special jack for a large truck. For the structure, a base screw sleeve is installed on the base of the jack; a lifting flange is arranged on a spiral lead screw A; a lifting flange hole is formed on the lifting flange; a top flange is arranged on a spiral lead screw B; a top flange hole is formed on the top flange; an internal thread on the body of the spiral lead screw A is connected with an internal thread in the middle of the base screw sleeve; an external thread on the body of the spiral lead screw B is connected with an internal thread in the middle of the spiral lead screw A; and a spiral bolt is connected with the spiral lead screw A via the base screw sleeve.

Description

technical field [0001] The invention relates to a structure of a jack, in particular to a structure of a special jack for a large truck, and belongs to the technical field of mechanical tools. Background technique [0002] The jack is a commonly used tool with a relatively simple structure. The common structure is composed of a screw rod with an external thread and an internal thread. However, due to the relatively simple structure of the current jack, there is a problem that the height of the large truck is low when used, and the height of the small car is high. , Protrusion is low, can not meet the defect of using more space. Contents of the invention [0003] The object of the present invention is to provide a special jack structure for large trucks with simple structure, ultra-low height, high extension, and the space for various large trucks, so as to overcome the above-mentioned defects of the existing jacks. [0004] The technical solution adopted by the present in...
