Abstract
The utility model provides a height adjusting and positioning device used for a seat or a footrest of a dining chair for kids. The dining chair includes a support post arranged on a bottom footstand in a slightly leaning back manner and equipped with a height-adjustable seat board and a height-adjustable footrest board. The back of each of the seat board and the footrest board is provided with a screw hole and positioning bosses. The support post is provided with longitudinal long groove holes and a plurality of positioning holes arranged at intervals at positions corresponding to the seat board and the footrest board respectively. The seat board and the footrest board are fastened on the support board with knob screw rods penetrating through the long groove holes. At the same time, the positioning bosses are inserted into the positioning holes. Thus, the positioning bosses of the seat board and the footrest board can withdraw from the positioning holes only by releasing the knob screw rod, so that height adjustment and positioning of the seat board and the footrest board can be realized. Therefore, height adjustment and positioning of the seat board and the footrest board can be facilitated.
Description
Technical field
The utility model relates to and setly on the support column of Chair for baby having meal take plate and pedal is respectively provided with positioning convex portion behind, make to plug together on the locating hole of arbitrary height set on this support column, and will take plate or pedal is locked on support column with knob screw rod, enable pass is crossed loosening of knob screw rod and is screwed, and just can operate easily the adjustment of taking plate or pedal height.
Background technology
About our known Chair for baby having meal, mainly to comprise the two chair foot rests of reclining relatively and backward, and establish a chair back and a service plate between the upper end of two chair foot rests, and not only between two chair foot rests below the chair back but also be provided with the seat that can take for child and the pedal of foot support.
Simultaneously, the above-mentioned both sides of taking plate or pedal, to sleeve in the set corresponding chute of opposite position inside two chair foot rests, and take plate or pedal can be by firm being fixed between two chair foot rests in order to allow, conventionally all can be between two chair foot rests up and down everywhere, locking has fixed head and fixed bar, allows beyond distance between two chair foot rests is fixed, and allows the two chair foot rests can be taking plate or pedal urgent sharing tightly.
Otherwise, while taking plate or pedal to different height and position if adjust, just must first fixed head and fixed bar between two chair foot rests be loosened, allow two chair foot rests be after loose condition (of surface), beginning can allow to be taken plate or pedal and detaches in originally fixing chute, after moving to again in other chute, then fixed head and fixed bar locking, make and take plate or pedal again by urgent being combined between two chair foot rests tightly.
Therefore, the above-mentioned differing heights adjusting operation mode of taking plate or pedal, very trouble and inconvenience, and also must use Wrench to carry out.
Utility model content
Edge is, in order to improve eat superior seat or pedal adjustment of aforementioned child, highly operate difficult problem, the utility model is to support in installing the support column corresponding position of taking plate or pedal, offer the long slot bore that can pass for a knob screw rod, take plate or pedal and be provided with the screw that can screw togather for knob screw rod in corresponding position behind, and number positioning convex portion, simultaneously on the support column of each positioning convex portion corresponding position, offer spaced several locating hole, enable pass is crossed the positioning convex portion of taking plate or pedal and is plugged together on the locating hole of differing heights, again knob screw rod is screwed, can be locked on the support column of predetermined At The Height taking plate or pedal, and then make the operation of adjustment more easy.
The utility model solves the technical scheme that its technical problem adopts: comprise the vertical support column for reclining slightly backward of establishing on a bottom foot base, and in support column upper end, fix one of a chair back and height adjusting and take plate and a pedal, and on the support column of taking plate and pedal corresponding position, be longitudinally provided with respectively long slot bore, and in long slot bore both sides again longitudinal separation be provided with a plurality of locating holes; The another place, behind that this takes plate and pedal respectively establishes a screw and is arranged in place, screw both sides and is provided with the positioning convex portion that can insert above-mentioned locating hole, is respectively provided with again knob screw rod simultaneously and passes the long slot bore on support column and will take plate and pedal is locked on support column.
The beneficial effects of the utility model are, by after the loosening of above-mentioned arbitrary knob screw rod, can make the positioning convex portion of taking plate or pedal behind detach in the locating hole of support column, allow take plate or pedal can be along long slot bore and upper and lower sliding onto after predetermined At The Height, again knob screw rod is screwed and is made the positioning convex portion of taking plate or pedal to insert again in the locating hole of corresponding position, and then allow and take plate or pedal by firm being locked on support column, therefore taking the adjustment of plate or pedal height, order can more easily and fast complete.
