Description

The handrail height adjusting device

Technical field

The handrail that the utility model relates to the chair tool can carry out a kind of structure of Height Adjustment, and enable pass is crossed the simplification of structural detail and its structure, allows manufacturing cost reduce and makes assembling more apparent easily, and then make the economic benefit of technology more promote.

Background technology

About the handrail of office chair, can carry out the structure of Height Adjustment, according to its kenel, have different designs, as the seat of TaiWan, China bulletin TW477200

The lifting structure of hand, be the positioning pedestal of chair cushion both sides assembling to be close to the support support that sets up be that to adopt tough matter integrally moulded, and be formed with indent and the interior pipeline section of going into tool multiple tracks tooth portion comes corresponding cover to be incorporated into the outer segment that correspondent section falls to also offering notch to form in a routine aspect; To this support support then correspondence run through into handrail and accept pipeline section first housing region, in addition to handrail accept pipeline section in addition second housing region that forms of side with face hole that tube wall opens mutually and then can supply to detain and establish therebetween by signature group body, its center of gravity paragraph fulcrum of clip parts that its elastic top is supported is can permanently protect to be resisted against to help the support outer side edges, deducts into support support respective teeth portion and make clip component ends protuberance be elasticity; By this, come for hand push prominent set out handrail accept pipeline section outside by giving as security part, can make elasticity card metacarpus spare break away from respective teeth portion, operate as the Height Adjustment of carrying out required rising or decline.

Yet, above-mentioned armrest support is made up of an interior pipeline section and outer segment at least, and then make the lower end of armrest support and positioning pedestal link, the upper end that this handrail is accepted pipeline section then links with handrail, in handrail is accepted pipeline section, install clip parts and a spring simultaneously, and its outside installs one by giving as security part; So the unitary construction of the adjusting device of this handrail height is not only comparatively complicated, and allow the cost made improve many beyond, also allow the program of assembling between its each element simultaneously, more apparent trouble be difficult for, with using other aid just can assemble.

The utility model content

Adjust structure in order to improve aforementioned handrail height, its constructional complexity, with the problems such as trouble in the assembling, the utility model provides a kind of and is provided with wearing of the continuous locating slot of tool closes support sector on armrest support, handrail below then links one and is sleeved on this and wears the cunning of closing in the support sector and close portion, installing one is subjected to the outside pushing tow of spring outside sliding the portion of closing then, and can insert the setting element in the locating slot, and then allow beyond the structure of whole handrail can simplify, more make between its each element and can fit together easily, simultaneously needn't use any instrument again, just can assemble.

The technical scheme that its technical problem that solves the utility model adopts is: comprise an armrest support, with one wear and close on armrest support and the handrail of liftable location, wherein, the upright side of stretching is provided with wearing of continuous locating slot and closes support sector on this armrest support, and this continuous locating slot comprises a long straight slideway again, with the block groove that is positioned at this slideway one side or the consecutive intervals setting of place, both sides, in addition this handrail below connect establish one with wear the cunning of closing support sector's fit and close portion, and the order cunning is closed the setting element that portion lateral surface place installing one is subjected to the outside pushing tow of elasticity, and the inboard of this setting element is convexly equipped with a guide sliding part that can stretch in the slideway of locating slot, convexes with in the one or both sides of this guide sliding part again simultaneously to insert or to recess the location division that plugs together on the block groove with the advance and retreat of setting element.

Described handrail height adjusting device, wherein: the cunning of this handrail is closed the portion side and is arranged with one and can holds groove for what setting element was installed with, and making this place, two ends of holding in the groove be provided with the embedding hole respectively, the two ends of setting element correspondence then are provided with the tuck pointing portion and the elasticity buckling parts that can embed this two embeddings hole.

Described handrail height adjusting device, wherein: this holds, and be equiped with in the groove can be to the spring of the outside pushing tow of setting element.

The beneficial effects of the utility model are, except pushing easily or releasing operation can carry out more can simplifying the structure of whole adjusting device the adjustment of handrail lifting, and the order assembling is also more easy by above-mentioned, so improve make, the trouble in the assembling.
