[0022] The following will be combined with the drawings in the embodiments of the utility model to clearly and completely describe the technical solutions in the embodiments of the utility model. Obviously, the described embodiments are only part of the embodiments of the utility model, not all of the embodiments. Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0023] like Figure 1-Figure 12 A specific embodiment of a bolt-free quick-installation shaft of the utility model is shown: comprising a column 1 and a wall panel 2, wherein the column 1 and the wall panel 2 enclose a shaft, and further comprising a plurality of assembly module units, each of which comprises a cross piece 3 and a dovetail bar 4, wherein the upper portion of the cross piece 3 is provided with a dovetail bar 4, and both ends of the dovetail bar 4 are installed in the column 1, and the wall panel 2 and the cross piece 3 are fixed between the two columns 1 through the dovetail bar 4 to form a force-bearing body;

[0024] Specifically, the cross section of the column 1 is L-shaped, and the outer corners of the column 1 are rounded to increase the structural strength, improve safety, and reduce the risk of personal injury;

[0025] Specifically, the two connection ports of the column 1 are dovetail groove structures 11, and the ends of the dovetail strip 4 match the dovetail groove structures 11 and can slide up and down along the dovetail groove structures 11;

[0026] Specifically, the cross section of the cross piece 3 is H-shaped, and the lower ends of the dovetail bar 4 and the wall panel 2 are clamped in its groove; the groove width of the cross piece 3 is the same as the thickness of the dovetail bar 4 body and the wall panel 2, which increases its load-bearing capacity and facilitates the installation of the wall panel 2 and the dovetail bar 4, thereby improving the overall performance.

[0027] Installation process:

[0028] 1. First, erect the two matching columns to the installation position, use the cross bar to locate the distance in the middle, and then use the dovetail strip to insert it into the corresponding dovetail grooves of the columns on both sides, and then press it into the upper groove of the cross bar after it is stuck (such as Figure 8 shown);

[0029] 2. Insert the wall panel into the slots on both sides of the column and press it into the dovetail strip in the horizontal groove. At this time, the dovetail strip will completely fix the columns on both sides and will not fail due to reverse rotation (such as Fig. 9 shown);

[0030] 3. Install the cross bar on the upper part of the wall panel, clamp the lower groove of the cross bar to the upper surface of the wall panel, then clamp the dovetails on both sides of the dovetail strip into the dovetail grooves of the columns on both sides, and press them into the upper groove of the cross bar (such as Fig.10 shown);
