- the first sliding piece 21 and the second sliding piece 22 are also provided with a matching chamfered portion 1 21c and a chamfered portion 22c, respectively.
- the middle connecting rod 20 and the cross beam 11 are pulled, the chamfered portion 1 21c and the chamfered portion 22c first contact and embed with each other, so that the first sliding piece 21 and the second sliding piece 22 are tightened with each other, which can effectively prevent the middle connecting rod 20 and the cross beam 11 from being pulled apart during lateral adjustment.
- FIG. 12 another embodiment is shown, in which the two cross beams 11 and the second cross beam 11' in the cross beam assembly 10 are two hollow pipes with different cross-sectional sizes, wherein the second cross beam 11' can be inserted into the cross beam 11 of another set of cross beam assemblies 10.
- the two sets of cross beam assemblies 10 are mutually inserted and can be laterally extended and retracted to achieve the purpose of adjusting the frame size.
- a four-legged lifting platform can connect two sets of frames by lengthening the first connecting member 12 or the second connecting member 13, and at the same time clamping the crossbeam assembly 10 of the two sets of frames to connect the two sets of lifting platform frames into one.
- the four-legged lifting platform welds the two sets of frames into one through the middle beam. This solution not only increases the welding cost, but also makes it inconvenient to package and transport the frames after welding.
- the connection method disclosed in this embodiment not only greatly improves the overall structural strength of the frame and enhances the stability of the lifting platform, but also effectively reduces the use of connecting beams, reduces packaging and transportation costs.
