The utility model content

Technical problem to be solved in the utility model is to provide a kind of shank that is different from the prior art structure by guiding mechanism, and this mechanism has realized the multi-angle adjustment that shank leans on well, and desirable comfort is provided when taking to the child.

The utility model solves the problems of the technologies described above the technical scheme that is adopted: this shank is by guiding mechanism, the seat support and the shank that comprise child's high chair or perambulator lean on, it is a pair of in order to connect the connector that seat support and shank lean on to it is characterized in that it also includes, with the gear plate that has a plurality of screens grooves on a pair of periphery, wherein an end of connector is connected with seat support, the other end is provided with a pin-and-hole, with be located at respectively shank by and the gear plate on a microscler through hole and the position of a pin-and-hole corresponding, an articulated part passes connector successively, gear plate and shank articulate the three by last hole and are integral; Lean in shank in addition and be provided with a jack, a spacing backing pin that can snap in the groove of gear integrated circuit board position is housed in the jack, and between spacing backing pin and articulated part, is connected with an extension spring.

Described connector is designed to a cap-like structure, its covering and fixing described gear plate.

Can adopt the clamp-close type syndeton between described connector and the seat support.

The described shank periphery that right both sides are provided with the position of microscler through hole and jack that keeps left has the arc surface projection, and described connector is provided with in order to hold the accommodation section of this arc surface projection.

Compared with prior art, advantage of the present utility model is: lean on guiding mechanism by shank provided by the utility model, simple in structure, easy to operate, lean on by length direction pulling shank along microscler through hole, shank is leaned on can pivot with respect to seat support around rivet, and make spacing shelves pin be stuck in one of a plurality of screens grooves of gear plate, and obtain the suitable angle of shank closing, have comfort when making the child take.

The specific embodiment

Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.

Fig. 4 is equiped with according to shank of the present utility model by the child of guiding mechanism with high pin dining chair, this dining chair comprises a chair frame 8, a seat support 1, a service plate 9, and wherein shank is mounted on the seat support, cooperates guiding mechanism, can reach the angle adjustment that shank leans on, and the structure of this guiding mechanism is as follows:

As Fig. 1 and shown in Figure 3, the guiding mechanism that this shank leans on includes a pair of connector 4, a pair of gear plate 3 and spacing backing pin 6 and extension spring 5 etc., wherein:

A pair of connector 4 is positioned at shank by the and arranged on left and right sides on top, in order to connect shank by 2 and seat support 1.This connector 4 is designed to a cap-like structure, can cover and fixing described gear plate 3.Wherein one of this connector 4 combines with seat support 1, and both adopt the syndeton of clamp-close type, so both ease of assembly, and it is firm to connect again.The other end of connector 4 has a pin-and-hole 41 and in order to hold the accommodation section 42 of shank by the arc surface projection of tip-end-side periphery.

A pair of gear plate 3 also is positioned at shank and leans on 2 both sides, is sandwiched in connector 4 and shank and leans between 2, and be limited in the connector 4.These gear plate 3 usefulness iron plates are made, and have the screens groove 32 of a plurality of circular arc dentations on the periphery of its rounded lower portion front side, and there is a pin-and-hole 31 center, and is corresponding with the pin-and-hole 41 on the connector.

Shank is an arc surface projection 21 by the front side periphery on top, 2 left and right sides, and there is a microscler through hole 22 and the pin-and-hole 23 corresponding to screens groove 32 on the gear plate corresponding to pin-and-hole on gear plate and the connector at heart place therein.Gear plate 3 is combined in the inside of connector 4, and after connector 4 fastens with seat support 1, pin-and-

hole

41,31 and shank that one rivet 7 passes on connector, the gear plate successively lean on last microscler through hole 22, make shank lean on 2 to be articulated on the seat support 1, shank can slide on the length direction of microscler through hole 22 with respect to seat support 1 by 2 thus, and can pivot with respect to seat support 1 around rivet 7.Spacing backing pin 6 then passes shank by last pin-and-hole 23, and by the restoring force of an extension spring 5, can snap in arbitrary screens groove 32, and make shank lean on 2 to obtain suitable angle, have more comfort when making the child take, to adapt to the comfort requirement of the virgin different user modes of different baby children, baby (have a meal, rest etc.), cooperate with leaning against to adjust simultaneously.And two of described extension spring 5 is connected on rivet 7 and the spacing backing pin 6, is formed with the baffle plate 24 of these spring 5 spacing usefulness in the bottom that shank leans on, and is used for placing restrictions on spring and horizontally slips.

When user's desire adjustment shank leans on 2, only need shank by 2 pullings forward, make spacing backing pin 6 skid off the screens groove 32 of position retaining plate, extension spring 5 this moment is compressed because of rivet 7 moves forward along microscler through hole 22, so shank can pivot with respect to seat support 1 around rivet 7 by 2, and by the restoring force of extension spring 5, spacing backing pin 6 can be entrapped in the screens groove 32 of diverse location, shank is leaned on 2 can be according to user demand, and is fixed on the diverse location, carries out the section adjustment that shank leans on.This guiding mechanism is easy to operate, one-hand operation.

The gear plate design of present embodiment guiding mechanism has three screens grooves, thereby can make shank by 3 grades of adjustable angle are arranged, respectively as Fig. 5, Fig. 6, shown in Figure 7, shank wherein shown in Figure 7 is the level of state by angle and seat support seat board, thereby cooperate again and lean against adjustment, can make things convenient for child's into use that lies low.
