Description

High chair retractable mechanism

technical field

The utility model relates to a folding mechanism for a chair frame of a high chair for young children.

Background technique

A traditional high chair (or stroller) mainly has a chair frame, a seat, and a storage and dining tray connected to the armrest of the seat. The chair frame is mainly composed of a group of inverted V-shaped brackets, and each bracket is connected by front and rear foot bars. In order to facilitate carrying out and reduce packaging and storage volume, a folding mechanism is provided between the front and rear legs, and the inverted V-shaped support can be folded into two parallel rods when folded.

For example, the notification number is CN2783855Y, which discloses a "leg folding mechanism for children's high chairs". Toothed groove, the toothed groove can be used for implanting the spring and the engaging body in it, the engaging body can be forced to move completely into the toothed groove of the inner cover body by means of the moving key on one side of the outer disc body, so that the inner and outer discs can be freely Rotation, on the contrary, by the force of the spring, the engaging body is respectively interposed between the toothed grooves of the inner and outer discs, so as to limit the rotation of the inner and outer discs, so as to obtain the folding and opening of the front and rear legs. There is also a "high chair folding device" disclosed by the notification number CN2624737Y. These two patent cases all disclose the structure of the high chair folding device, and their common feature is the design of the switch button. The release action of the switch button will inevitably be stuck.

Contents of the invention

The technical problem to be solved by the utility model is to provide a folding mechanism that is novel in structure, easy to operate, and can easily realize the folding action of the high chair in view of the above-mentioned prior art.

The technical scheme adopted by the utility model to solve the above-mentioned technical problems is: the folding mechanism of the high chair includes an inner cover body and an outer cover body that can be combined with each other, and a inner cover body combined with the outer cover body is provided to limit The inner and outer covers generate sliding blocks and compression springs that rotate relative to each other. The rear end of the inner cover is extended downwards with a rear tube seat that can be inserted and fixed by the rear leg rod, and the front end of the outer cover is extended downwards. The front pipe seat that can be inserted into and fixed by the front foot rod is characterized in that a pipe seat is extended at the rear end of the outer cover, a rotatable handle is installed on the pipe seat, and a pull wire is arranged inside the handle. One end is fixed on the handle, and the other end passes through the handle, the spring is fixedly connected with the sliding block; the sliding block is arranged in the sliding groove on the outer cover, and the inner cover is provided with a Contradictory limit structure.

The above-mentioned high chair folding mechanism, wherein a tube hole is provided on the upper part of the sliding block, which can be used for putting the spring into it, and there is an elongated hole in the middle part, which can be inserted into the guide post on the outer cover body, and the lower part can be connected with the inner The limit structure on the cover body is in conflict with the inclined surface that facilitates sliding in the sliding groove.

In the aforementioned highchair folding mechanism, the position-limiting structure on the inner cover is a rib plate formed inside the inner cover.

In the aforementioned high chair folding mechanism, the handle is mainly composed of a curved handle tube with an opening facing forward and a rubber sleeve on the handle tube, and a handle cover is installed at the front end of the handle tube.

Compared with the prior art, the utility model has the advantages that: the folding mechanism of the high chair of the utility model drives the pull wire through the rotation of the handle, and then the pull wire drives the sliding block to move, so that the sliding block and the limit rib of the inner cover The plates are separated, so that the inner cover and the outer cover can rotate relative to each other, so as to realize the purpose of folding the high chair. Therefore, the design is novel, the operation is convenient, and the user's push is facilitated by the setting of the handle.

Detailed ways

The utility model is described in further detail below in conjunction with the accompanying drawings.

Please refer to Fig. 1-Fig. 6, the high chair folding mechanism of the present invention includes an outer cover 1, an inner cover 2, a handle 6, a sliding block 3, a pull wire 5 and a compression spring 4, in:

The main body of the outer cover body 1 is disc-shaped, and its front end is extended downwards with a front pipe seat 11, which can be inserted into the front foot bar 7 and fixed with screws. And the rear end is upwardly provided with a tube base 12, which can be inserted and fixed by the handle 6. The central part of the outer cover body 1 has a sliding groove formed by several ribs, which can be used for the sliding block 3 to slide therein, and there is a hollow cylinder in the middle part, which is used for the rivets to pass through and combine with the inner cover body.

The main body of the inner cover body 2 is also a disc body, and its rear end is extended downwards with a rear pipe seat 21, which can be inserted into the rear foot rod 8 and fixed with screws. The central part of the inner cover 2 has a limiting rib 22 which can be in conflict with the sliding block 3 to limit the relative rotation between the inner cover 2 and the outer cover 1 . There is a round hole in the middle, which can be inserted into the hollow cylinder on the outer cover, and can be closely matched with the outer cover through the joint of rivets to form a housing of a retractable mechanism.

The sliding block 3 is arranged in the sliding groove of the outer cover body 1, and the upper part of the sliding block is provided with a tube hole 31 for the compression spring 4 to be put in, and there is an elongated hole 32 in the middle part for the insertion of the guide post 13 on the outer cover body. It acts as a guide for the movement of the sliding block 3. The lower part is designed as an arc-shaped inclined surface 33, which can conflict with the limiting ribs 22 on the inner cover.

Handle 6 is assembled on the pipe seat 12 of outer cover body, and it is mainly assembled by the curved handle pipe 61 of an opening and the rubber sleeve 62 that is covered on the handle pipe, and the front end of handle pipe is equipped with handle cover 63.

Backguy 5 adopts steel wire, and its one end is fixed on the handle pipe 61, and the other end passes through handle pipe 61, after compression spring 4, links to each other with slide block 3. The sliding block 3 can move upwards in the sliding groove through the pulling of the stay wire. When it is separated from the limiting rib 22 on the inner cover body 2, the inner and outer covers can rotate freely to achieve the folding or opening of the front and rear foot rods. open action.

When the folding mechanism is assembled, a plastic cap 65 and a handle tube inner plug 64 are fixed on the handle tube 61 with rivets, the rubber sleeve 62 is placed on the handle tube 61, the pull wire 5 passes through the handle tube 61, and then the upper and lower halves The handle cover 63 is fixed on the handle pipe 61 with screws, and after the stay wire 5 passes through the outer cover body 1, the compression spring 4 and the sliding block 3, it is fixed on the sliding block 3, and then the sliding block 3 is placed on the sliding side of the outer cover body 1. In the groove, at last the inner and the cover body are riveted together with rivets, that is to say, the highchair folding mechanism of the present utility model is assembled.

Its working principle is as follows: Hold the left and right handles with both hands, and then turn them outward 90 degrees at the same time, the sliding block moves upwards in the sliding groove of the outer cover under the pull of the pull wire, at this time, the limiting ribs in the inner cover body are in contact with the sliding block To disengage, lift the highchair slightly upwards or push the rear leg bar forward to realize the folding.
