Embodiment Construction
[0029] The present invention will be described in further detail below in conjunction with the embodiments of the drawings.
[0030] Such as Figure 1 to Figure 14 As shown, the expansion joint device with anti-sagging function for non-motor vehicles of this embodiment includes a first comb-tooth plate 1 and a second comb-tooth plate 2 that are staggered and can be relatively telescopic. Among them, the first comb-tooth plate 1 It is a cross seam plate, and the second comb-tooth plate 2 is a fixed plate. A first comb tooth gap 3 is formed between the comb teeth of the first comb tooth plate 1, and a second comb tooth gap 4 is formed between each comb tooth of the second comb tooth plate 1. The above-mentioned structure is the same as the existing expansion joint device, and the description will not be expanded here. Of course, it is also possible to adopt a structure in which the first comb-tooth plate 1 is a fixed plate, and the second comb-tooth plate 2 is a cross seam plate....
