Description
The utility model relates to carriage for children, refers to a kind of carriage for children stretcher anchor fitting especially.
The design of carriage for children, its each parts should the utmost point place stress on practicality, safety.Right existing carriage for children, its arbor directly runs through stretcher, stretcher slippage when trampling rotation is fixed and prevented to the arbor end that protrudes the stretcher outer rim by interspersed pin rod or iron wire loop, but this kind connects fixed sturcture, the arbor end that exposes, pin rod end or iron wire loop be the scratch child very easily, as Fig. 1; The another kind of folder fixed tube that protrudes out with stretcher one end moulding, the groove of the flange blocking handle axial end that is convexly equipped with by folder fixed tube endoporus impels arbor to be fixed on the folder fixed tube, as Fig. 2.But this kind structure, the folder fixed tube that protrudes out still causes trips, and plastic stretcher, and the arbor that very easily is rotated scrapes damage, produce and to skid, to make also and waste time and energy; Existing its parts interchangeability is also poor.
The purpose of this utility model is to try hard to overcome the above-mentioned shortcoming of the stretcher fixed sturcture existence that has carriage for children now, and a kind of comparatively perfect carriage for children stretcher anchor fitting is provided.
The purpose of this utility model is achieved in that carriage for children stretcher anchor fitting, comprises stretcher, arbor, it is characterized in that being the square groove hole of stretcher rear end moulding one coherent perforation; Intercalation one drawing piece in the square groove hole; This drawing piece is provided with the circular hole that is slightly less than the arbor diameter, and the circular hole periphery has several slot holes; Drawing piece is forced cover to be through at the arbor end and is the tight space that is fixed on the arbor and places the square groove hole of stretcher of overlapping of pawl of umbrella.
Above-mentioned design not only makes arbor, and sliding sleeve in stretcher and can slippage securely, and its end no longer includes the chance that scratch drives children, and is safe, practical.
Below by drawings and Examples the utility model is described further again:
Fig. 1 is existing carriage for children stretcher fixed sturcture scheme drawing;
Fig. 2 improves structural representation for existing carriage for children stretcher;
Fig. 3 is the utility model decomposition texture scheme drawing;
Fig. 4 is the three-dimensional combination of a utility model cross-sectional schematic;
Fig. 5 is the utility model plane combination cross-sectional schematic.
Among the figure: 10 stretchers, 11 square groove holes, 12 axis holes, 20 drawing pieces, 21 circular holes, 22 slot holes, 30 arbors.
As shown in the figure: drawing piece is the sheet metal of a nick shape, so though its central Circularhole diameter is slightly less than the arbor diameter, mat elasticity and can force to be inserted in arbor, and form pawls the tight pawl of drawing piece is lived on arbor by all establishing a plurality of slot holes, the space, square groove hole that places stretcher to establish firmly, reach to make and realize between stretcher and the arbor improving secure attachment together, not only practicality but also safety, relevant parts are convenient to again make, are transported and assemble the simple and convenient of converting.
