Technical field

The utility model is the service plate adjusting device on the juvenile high chair tool, refers in particular to a kind of service plate front and back that can make and adjusts its position, and the device of being located.

Background technology

The child is high, and the pin dining chair is of a great variety, and also all is provided with service plate mostly on dining chair, and service plate also can be done the adjustment location of front and back position simultaneously, and is too numerous to enumerate; And as United States Patent (USP) 4,807,928 invention, it establishes two relatively and by spring 56 first of a relative motion of pulling of drawing, two door bolt plates 52, each outboard end below of 54 all is provided with Nie and closes portion 70, make first, two door bolt plates 52,54 can build-in in the set attachment area 20 of handrail 18 lateral surfaces of high chair 10, and above-mentioned mechanism be again mail in service plate 26 be divided on, lower pan portion 46, between 48, simultaneously first, respectively be provided with the E type embedding that is symmetry on the two door bolt plates 52,54 and decide groove 58,60, and make pin plate 76, the adjustment bolt 86 of 78 1 ends can stretch on wherein arbitrary position, and pin plate 76,78 is that pivot is fixed on the lower pan portion 48, and make pin plate 76 again, the manipulation bolt 84 that 78 the other end is set is to stretch in the two set operation holes 92 of a control handle 44 1 ends, and this operating handle 44 is to be subjected to 96 pushing tows of a spring and to move towards service plate 26 is inner simultaneously.

So when control handle 44 is spurred displacement outwardly, make pin plate 76,78 be rotation relatively inwardly, and then make two pin plates 76, the adjustment bolt 86 at 78 1 end places, decide the parallel ditch 62b of groove 58,60 from embedding, be retracted into common trench 62x among the 66b, among the 66x, so can push-and-pull service plate 26 do moving that front and back position adjusts, and after service plate 26 moves to the desired position, just control handle 44 can be loosened and make its automatic homing, the interlock pin plate 76 then, 78 also backswing make the adjustment bolt 86 on the pin plate 76,78, clip is gone into other parallel ditch 62a, 66a or 62c among the 66c, make service plate 26 location and can't move; Aforesaid service plate adjusting device is no doubt operated the profit of still finding a great convenience, and is not only many and complicated again for reaching the employed the number of components of its purpose, causes the uncertainty in its action, and comparatively bothers time-consumingly when assembling again, and the while cost is also comparatively high.

Goal of the invention

The utility model main purpose is to overcome the desirable not to the utmost disappearance of above-mentioned known service plate position regulator, and a kind of designs simplification, the more convenient service plate front and back position adjusting device of operation are provided. Technical scheme

The technical solution of the utility model is: adjust location structure before and after a kind of service plate of Chair for baby having meal, on the preceding tray frame of a dining chair, establish one can before and after adjust the service plate of position and location, it is characterized in that wherein: set firmly the guide bracket that has a guide groove in the middle of on the service plate support, and be provided with relative a plurality of caulking grooves in the one-sided or both sides of guide groove, and cunning is established one and is pulled the control seat in guide groove, and pulling the upright pillar of establishing in the rear end of controlling seat, enable to intert in the elongated hole of tiltedly being established on the clipping block, and a side that makes clipping block stretches and is provided with the embedding fixed end, and makes this embedding fixed end can stretch on the caulking groove; At place, service plate bottom surface, be provided with the slide groove portion that can be installed with the slippage of clipping block leading simultaneously with respect to clipping block.

Adjust location structure before and after the service plate of aforementioned Chair for baby having meal, wherein the both sides of guide bracket are provided with the microscler guide hole of symmetry, and are provided with the guide pillar that can be inserted in wherein on the service plate bottom surface with respect to microscler guide hole.

Adjust location structure before and after the service plate of aforementioned Chair for baby having meal, wherein pull the control seat and respectively be provided with the slot part that holds that is forward and backward opposition, and hold two and to establish a spring between the slot part with service plate opposite face place. The invention effect

The beneficial effects of the utility model are: the utility model ties up to and sets firmly one on the tray frame and can make one to pull control seat and be slidedly arranged on wherein guide groove, and make the guide groove both sides have a plurality of caulking grooves, make and pull clipping block one side of being overlapped on the upright pillar of establishing in a control seat adjacent end place and stretch the embedding fixed end of establishing and stretch in wherein, and making pillar intert on the clipping block is the setting of an elongated hole of tiltedly establishing, and complex phase can be installed with the slide groove portion of clipping block slide guide for place, the service plate bottom surface tool of clipping block; If pull to draw and pull control seat forward during slippage, pulling the elongated hole of the pillar meeting pushing tow clipping block on the control seat leads inwall and makes it towards intrinsic displacement, the embedding fixed end of clipping block is broken away from caulking groove, make the service plate can be by the hand push-and-pull and the front and back slippage, make and loose one's grip to the desired location and make and pull the control seat and reset, make clipping block reset once again and its embedding fixed end stretched in the caulking groove, allow the structure of service plate adjusting device more simplify, make assembling more simple and easy, reduce cost, and order operation, location are more easy.
