The specific embodiment
Embodiment describes in further detail the utility model below in conjunction with accompanying drawing.
See also shown in Figure 1, it is the high pin dining chair of an infant, it roughly comprises a chair frame 1 that can draw in, launch, and is installed with seat support 2 on the chair frame 1, and seat support 2 usefulness are taken for the child, and can be with seat support holder height by chair frame 1, there is handrail 3 the seat support both sides, are installed with a service plate 4 on the handrail 3, and this service plate 4 can cooperate guiding mechanism, reach the purpose of forward and backward displacement of service plate and location, and the structure of this guiding mechanism is as follows:
Please refer to Fig. 2-shown in Figure 8, service plate guiding mechanism of the present utility model is arranged between the upper and lower cover 41,42 that service plate is divided into, mainly form by institutes such as handling pull handle 5, left and right adjusting rod 6a, 6b, alignment pin 8, spring 7, wherein the lower cover 41 table portions in service plate are preset with the storage tank 411 that can be installed with the manipulation pull handle, handling pull handle 5 is installed with in this groove, and the handle part is exposed to outside the service plate, can make the front and back slippage on groove of manipulation pull handle with pulling moving handle.And there is a similar trapezoidal head inner end of this manipulation pull handle 5, and has one to be symmetrical oblique long chute 51 respectively in the both sides of head, is used for inserting for the guide pillar on the adjusting rod 61.And be provided with slotted eye in the roughly middle section position of handling pull handle 5, in be installed with spring 7, by this spring 7 this manipulations pull handle 5 is had towards the mobile gesture in service plate inside.
Left and right adjusting rod 6a, 6b are " L " shape member that is symmetry, one end place all convexes with a guide pillar 61, corresponding respectively being inserted in the oblique long chute 51 of handling pull handle, an alignment pin 8 is equipped with at other end place respectively, the head of alignment pin 8 is respectively towards the handrail side of dining chair, and stretches in outward outside the long boss 413 in inboard of service plate bottom.And be respectively equipped with a plurality of by locating hole arranged in a straight line 31 in the inboard of dining chair two side handrails, by handling pull handle and the drive of adjusting rod separately, alignment pin 8 can stretch into or withdraw from arbitrary locating hole 31, alignment pin 8 makes service plate have different front and back position (as Fig. 9-shown in Figure 11) in different holes.
Again as shown in Figure 6, two bottom sides in the service plate lower cover also respectively is formed with two long boss that parallel 413,412, and on the long boss 412 in the outside, be formed separately guiding and location boss 414, lead and detents 32 with these boss 414 corresponding being formed with in the two handrails outside.When service plate is assembled mutually with seat support, the seat support handrail is embedded in by in formed groove of two long boss, and the boss 414 of service plate bottom is embedded in the groove 32 on the handrail, make moving forward and backward of service plate 4, both can be subjected to good guiding, and can prevent that service plate breaks away from handrail, service plate is again in conjunction with the location of alignment pin like this, make have between itself and the handrail well fixing.As remodeling, guiding and location also can be formed on the service plate with groove, and guiding that matches and location can be formed on the handrail with boss, both in conjunction with after the purpose that can reach guiding equally and locate.
By said mechanism service plate 4 can be slided and the adjustment section along groove 32 front and back, but be in course of adjustment for fear of service plate and come off, a spacing rib 52 and an elastic button 415 also have been formed separately at manipulation pull handle and lower cover bottom, and the elasticity rib 416 of colliding with spacing rib 52 is arranged on elastic button 415, as shown in Figure 8.Like this when service plate is adjusted to certain stroke, the spacing rib of handling on the pull handle 52 is collided with the elasticity rib 416 that covers down, this moment alignment pin 8 to also have one section elongated slot 33 that does not leave the seat inboard be that service plate can not be removed.Press elastic button 415 again and allow elasticity rib 416 break away from spacing rib, continue simultaneously to be pulled outwardly and handle pull handle 5, just can allow the alignment pin 8 on both sides leave the elongated slot 33 of seat inboard fully, service plate can be taken out.After action is finished because under the elastic force effect of the screen resilience of spring 7 and elastic button 415, elasticity rib 416 is reset to normal condition again.
During use, application of force pulling control crank 5, manipulation pull handle 5 is moved forward, this moment two adjusting rod 6a, 6b is relative to moving inwardly, and then two withdraw from the locating hole 31 of alignment pin 8 from the handrail on the adjusting rod, so can do moving of front and back position adjustment by the push-and-pull service plate, and after service plate moves to the desired position, just loosen and handle pull handle 5, the effect by spring 7 makes its self-return, two adjusting rod 6a then, 6b also is simultaneously relative to moving outwardly, alignment pin 8 is snapped in another locating hole, thereby make service plate location and can't move, and reach the purpose of adjusting the tableware front and back position and being located, this guiding mechanism can be operated by one hand, and is very easy.
Again as shown in Figure 2, the service plate 4 of this guiding mechanism is except by loam cake 42 and lower cover 41 be combined intos, on service plate, also be assembled with a washable service plate washed 43, be interlocked by protruding button and the elasticity button loop that has a hole clipping between the two and be combined into one, make and to wash service plate 43 and can unpick and wash at an easy rate and assemble, overcome the not easily removable and washable defective of traditional service plate, and this bottom design that can wash service plate becomes the plane, it both can be combined on the service plate use, can make service plate again separately and use.
