Abstract

The invention discloses an angle-variable adjustable jack which comprises a supporting platform, middle vertical columns and a supporting framework, wherein the supporting platform comprises a first supporting vertical beam, a second supporting vertical beam, a first supporting cross beam, a second supporting cross beam, and screw rods and fastening mechanisms of the screw rods which are arranged in the first supporting vertical beam and the second supporting vertical beam; the middle vertical columns comprise a first front vertical column and a first rear vertical column which are arranged on the first supporting vertical beam and a second front vertical column and a second rear vertical column which are arranged on the second supporting vertical beam; the screw rods and the fastening mechanisms thereof are respectively arranged in the first front vertical column, the first rear vertical column, the second front vertical column and the second rear vertical column; the supporting framework comprises a first framework edge beam, a second framework edge beam, a third framework edge beam and a fourth framework edge beam; the supporting framework is connected to the middle vertical columns through a connection device, and moves along the screw rods, serving as rails, in the middle vertical columns.

Description

technical field [0001] The invention relates to the field of mechanical manufacturing, in particular to a variable-angle adjustable jack. Background technique [0002] At present, in the development process of new technologies in various fields, lifting parts and then installing and fixing them is a commonly used support method. However, in practical applications, different external environments are produced along with different usage occasions, which requires us to develop more flexibly the jacking device to meet the changing needs, especially for the changes often involved in engineering. Angle adjustment problem. Therefore, it is a basic requirement to increase the flexibility of the device and reduce the cost to be able to design a device with simple structure, easy operation, adjustable parameters and low processing difficulty. At present, the jacks widely used in the market can only complete the lifting of the height in a specific direction, which has poor flexibilit...
