Detailed Description

The following description of the embodiments refers to the accompanying drawings.

Fig. 1 shows a structure of a sliding window on a cab of a construction machine, which may be a loader, an excavator, a bulldozer, or the like. The sliding window comprises a sliding window frame, inner side glass 4 and outer side glass 3, wherein the sliding window frame comprises an upper frame edge 1 and a bottom frame edge, the upper frame edge 1 is composed of two side frame edges and a top frame edge, and the bottom frame edge is spliced with the upper frame edge 1 to form a four-side window frame. The upper frame edge 1 is formed by bending and integrally forming a section bar.

As shown in fig. 2 to 4, the bottom frame is mainly composed of an outer frame 2 and an inner frame 5. The cross section of the outer frame edge 2 is approximately L-shaped as a whole, and the outer frame edge 2 is composed of an outer frame edge horizontal part 24 and an outer glass outer flange 23 which protrudes upwards from the outer frame edge horizontal part 24; the outer frame horizontal portion 24 is provided with four screw holes 21. Two limiting grooves 22 are further arranged on the horizontal part of the outer frame edge, the length direction of the limiting grooves 22 is consistent with that of the horizontal part 24 of the outer frame edge, and the cross section of each limiting groove 22 is triangular. The outer frame edge 2 is fixedly arranged on the bottom edge of the opening of the cab window.
