Detailed Description
Referring to fig. 3, the positioning member 3 of the chair adjusting device of the present utility model is formed by stacking a plurality of positioning pieces 4.
As shown in fig. 3 and 4, the positioning sheet 4 is a sheet-like body formed by pressing; the positioning sheet 4 is punched into a sheet by a die punching method, and simultaneously, a positioning portion 41 located beside one side, a coupling portion 42 and a penetrating portion 43 on the other side are punched by a punching method.
As shown in fig. 3 and 4, the positioning portion 41 is composed of a plurality of concave-convex positioning teeth 411.
As shown in fig. 3 and 4, the connecting portion 42 is formed by a concave groove 421 with a concave side and a convex post 422 with a convex side, the outer diameter of the convex post 422 matches with the inner diameter of the groove 421, so that the convex post 422 of the positioning plate 4a located on the upper side of the two positioning plates 4 stacked up and down can be embedded into the groove 421 of the positioning plate 4b located on the lower side, and thus the two positioning plates 4 stacked up and down can form a tight fit connection; the joint 42 of the present utility model is illustrated by the provision of two.
As shown in fig. 3, the penetrating portion 43 is formed by a through hole 431, and the penetrating portion 43 of the present utility model is exemplified by providing two through holes 431.
As shown in fig. 3, 4 and 5, the positioning member 3 of the present utility model is assembled by pressing a single piece of the positioning sheet 4 having the positioning portion 41, the coupling portion 42 and the through portion 43 by a die; then, the single positioning sheet 4 with the punched positioning part 41, the combined part 42 and the punched part 43 is automatically moved to the combined punching die to be overlapped in an automatic mode, and when another single positioning sheet 4 is overlapped on the single positioning sheet 4, the single positioning sheet 4 can be punched and combined; that is, the convex column 422 of the positioning plate 4a located at the upper side is embedded into the groove 421 of the positioning plate 4b located at the lower side by the punching force, so that two positioning plates 4a, 4b stacked one above the other can form a tight fit combination; the positioning sheets 4 are stacked and combined by stamping, when a plurality of positioning sheets 4 are combined into a preset thickness by stamping, the convex column 422 of the positioning sheet 4c at the lowest position is stamped by a stamping column A, so that the convex column 422 of the positioning sheet 4c at the lowest position is retracted upwards, the position where the convex column 422 of the positioning sheet 4c at the lowest position is arranged is concave, namely, the surface of the convex column 422 of the positioning sheet 4c at the lowest position can be kept to be a slightly flat shape without protruding, and the positioning piece 3 is assembled; it should be noted that, when the boss 422 of the lowermost positioning plate 4c is pressed and retracted upwards, all the positioning plates 4 above the lowermost positioning plate 4c can absorb the retraction amount of the boss 422 of the lowermost positioning plate 4c in a gradually decreasing manner.
The utility model has the effects that the positioning piece 3 is formed by stacking a plurality of positioning pieces 4; the positioning piece 4 of each single piece is provided with the positioning part 41, the combining part 42 and the penetrating part 43; the combining part 42 is composed of a concave groove 421 with a concave side surface and a convex column 422 with a convex side surface, the outer diameter of the convex column 422 is matched with the inner diameter of the groove 421, thereby the two positioning sheets 4 which are overlapped up and down, the convex column 422 of the positioning sheet 4a positioned on the upper side can be embedded into the groove 421 of the positioning sheet 4b positioned on the lower side, so that the two positioning sheets 4 which are overlapped up and down can form tight fit combination; therefore, the assembling engineering of the positioning piece 3 can be simplified, and the cost of the chair adjusting device can be reduced.
