Description

TECHNICAL FIELD

[0001] The utility model belongs to the technical field of jack, concretely relates to screw type key type stand column jack assembly structure. BACKGROUND

[0002] The jack is a commonly used mechanical tool, which is used for jacking heavy objects in the scenes of maintenance, installation and carrying, so as to carry out various operations. The jack generates a large jacking force by exerting a small force, so as to easily lift the heavy object. The jack has various types, including mechanical type, hydraulic type and pneumatic type. Each type has its unique structure and working principle. Taking the common hydraulic jack as an example, the working principle is based on Pascal's principle, that is, in a closed container, the liquid can uniformly transmit the pressure applied on it to each direction. When the operator injects high-pressure liquid into the hydraulic cylinder by a manual or electric pump station, the piston in the hydraulic cylinder is pushed upward by the liquid pressure, thereby lifting the heavy object. Conversely, when the heavy object needs to be lowered, the liquid in the hydraulic cylinder is released by controlling the oil return valve, and the piston is returned under the action of the gravity of the heavy object.

[0003] The existing key type stand column jack mounting joint mainly uses a guide sleeve, a half ring, a compression ring, a clamp spring and is complicated to install. The screw type stand column jack mounting guide sleeve needs to be rotated for a long time and consumes time. It needs to be rotated into one circle at a time, and the problem of slowly rotating out due to the loosening of the threaded compression ring during the use process in the later period is difficult to solve. The present application is designed in combination with the advantages of the key type and screw type stand column jacks. Rectangular threads are used as the engagement object, and the plug-in rectangular bar is used as the key blocking thread to slide out. Finally, only the compression disc needs to be fastened on the cylinder body by using the inner hexagonal bolt. The structure is convenient to install, saves time and is convenient to assemble.
