Description
Technical field
The utility model relates to seat, especially relates to the handrail of seat.
Background technology
Along with the lifting of Science and Technology Day in progressive step and efficient level, general furniture is kept outside its existing functional structure design, still needs and notices the practicality that is convenient for people to use.With regard to the seat with handrail, the handrail that group is established is not only kept the existing user's hand that supplies provides a handrail height to adjust structure by putting function, still needing, and the user who is beneficial to differing heights is by putting.Now, can be still rare to the device that handrail height is adjusted.
Summary of the invention
The purpose of this utility model provides a kind of handrail height adjusting device of seat of practicality.
The purpose of this utility model is achieved in that the handrail height adjusting device of seat, it comprises the chair back and handrail, handrail is assembled in chair back hypomere both sides, it is characterized in that: tool is established sliver in chair back hypomere both sides, and is sheathed for the through hole of establishing in the respective side tool with armrest rear end; Sliver outside tool is established the embedding ditch that is arranged above and below, and rear end, handrail bottom side articulates one and pulls piece, pulls piece and fastens with the embedding ditch for corresponding in connect the tool abaculus near the articulated section; Abaculus and embedding ditch cutting ferrule are with fixed armrest.
Above-mentioned design if will pull piece outwards pulls, makes abaculus and embedding ditch break away from the cutting ferrule state, can adjust height of armrests.By this, form a structure simplify, practical, adjust the easy handrail height adjusting device of operation.Wherein, the sliver inboard forms narrower shrinking section, connects the opening fit of tool outward for the through hole with handrail.Wherein, sliver outside tool is established the hole clipping that is arranged above and below; The through-hole wall of handrail is established one in corresponding hole clipping orientation tool and is held the hole for sheathed card pearl and flexible member, card pearl elasticity can be pushed up outward by flexible member, so that the card pearl is inserted in the hole clipping.Wherein, handrail back segment outside tool is established card article, is sleeved on the handrail bottom side for pulling piece in rotation, by the corresponding cutting ferrule with card article of the Ka Gou location of its top side.Wherein, pull the piece outer end and connect tool linking piece, pull button in order to user's finger.

The specific embodiment
Shown in Fig. 1-5: the utility model is in the chair back 1 hypomere both sides assembling handrail 2, and this chair back 1 is established sliver 11 in hypomere both sides tool, for holding the through hole of establishing in the respective side tool 21 sheathed with handrail 2 Hous; Sliver 11 is inboard to form narrower shrinking section, for through hole 21 outer opening 22 fits that connect tool of handrail 2; Moreover sliver 11 outside tools are established two many embedding ditches 13 that is arranged above and below of row and hole clippings 14, and handrail 2 bottom side Hou ends articulate one and pull piece 3, pull piece 3 and fasten with embedding ditch 13 for corresponding in connect tool abaculus 31 near the articulated section; Through hole 21 inwalls of handrail 2 are established one in corresponding hole clipping 14 orientation tools and are held hole 23 for sheathed card pearl 4 and flexible member 5, card pearl 4 elasticity can be pushed up outward by flexible member 5, so that card pearl 4 elasticity are inserted in the hole clipping 14; Handrail 2 Hou sections outsides tool is established card article 24, for pulling piece 3 rotations when being sleeved on handrail 2 bottom sides, can locate by card ditch 32 card articles, the 24 corresponding cutting ferrules of its top side; Pull piece 3 outer ends and connect tool linking piece 33, pull button in order to user's finger.
Shown in Fig. 1-4, at ordinary times, pull piece 3 and collapse in handrail 3 bottom sides, and by blocking ditch 32 and card article 24 cutting ferrules with certain location.Simultaneously, the abaculus 31 of pulling piece 3 is corresponding chimeric with the embedding ditch 13 of sliver 11, so but fixed armrest 3.
Shown in Fig. 1,6,7, when desire is adjusted handrail 2 height, can grip the linking piece 33 of pulling piece 3, will pull piece 3 turn outward, make card ditch 32 and card article 24 break away from the cutting ferrule state; Simultaneously, abaculus 31 also can break away from chimerism with embedding ditch 13; At this moment, get final product the height of upper and lower adjustment handrail 2; See also shown in Fig. 5,8, when moving handrail 2 up and down, card pearl 4 can cooperate and contracts in the flexible members 5 corresponding elasticity or elasticity is outstanding is inserted in the hole clipping 14 that is arranged above and below, so that accurate location at any time.Continue it, handrail 2 is adjusted to ideal height Hou, the rotatable piece 3 of pulling makes it collapse in handrail 2 bottom sides once again, and is corresponding chimeric with embedding ditch 13 by abaculus 31 simultaneously, handrail 2 can be fixed in ideal height.Wherein, embedding ditch 13 that the arrangement tool is established on the sliver 11 and hole clipping 14 orientation have corresponding relation; That is when as long as card pearl 4 elasticity of assembling are inserted in arbitrary hole clipping 14 on the handrail 2, piece 3 is pulled in expression, can make abaculus 31 accurate correspondences be inserted in embedding ditch 13, and locatees smoothly.By this, in order to operation.
By said structure, the following advantage of the true tool of the utility model as can be known:
1, establish sliver 11 for assembling handrail 2 in the chair back 1 both sides tool, and on handrail 2, articulate pull piece 3 for sliver 11 buckles location, so the utility model structure is simplified.
2, only to outwards pull piece 3, can adjust handrail 2 height up and down.Otherwise, will pull piece 3 and inwardly pull and fold, can fixed armrest 2.Therefore, operation of the present utility model is simple and easy.
When 3, moving handrail up and down, utilize card pearl 4 and the flexible member 5 corresponding hole clippings that are arranged above and below 14, can precisely reach the location really.
