Description

Telescopic stool

Technical Field

The utility model relates to a but field of furniture of vertical adjustment especially relates to a telescopic stool.

Background

The folding stool is an article which is frequently used when people are at home or out, people often need to sit and rest under the conditions of traveling, riding a train, standing for a long time and queuing and the like, people usually carry the folding stool, the height of the folding stool cannot be adjusted although the folding stool is convenient to carry, the comfort is poor, and a telescopic stool is improved and designed by technical personnel aiming at the problem.

Current telescopic stool includes the base and is located the bench board of base top, is equipped with split type bearing ring between base and the bench board, and the individual layer bearing ring is formed by the mutual lock joint of multi-disc buckle piece head and the tail promptly, the bearing ring is not less than two-layerly, and two liang of nestings of bearing ring, vertical sliding connection between the adjacent bearing ring, is connected through the buckle between the bearing ring of inlayer and the bench board, is connected through the buckle between outmost bearing ring and the base. The existing telescopic stool is in a stretching state and a bearing state, and the trend of mutual separation exists between the fasteners on the split type bearing ring, so that the bearing performance of the telescopic stool is influenced, namely the existing telescopic stool has limited bearing and needs to be optimized.

SUMMERY OF THE UTILITY MODEL

An object of the utility model is to provide a telescopic stool that the bearing is higher for prior art.

In order to achieve the purpose, the technical scheme of the utility model provide a telescopic stool, including base, bench plate, can dismantle between base and the bench plate and be connected with not less than two-layer bearing ring, two liang of nestings of bearing ring, bearing ring formula structure as an organic whole, the vertical spout that is equipped with of lateral wall of bearing ring, the side below of spout is equipped with the spacing groove, and the spacing groove forms first logical groove with the spout intercommunication, be equipped with the first logical groove complex slider on the bearing ring adjacent with inboard on the inside wall of bearing ring, the side that just is located the spout on the bearing ring inside wall is equipped with the first logical groove complex stopper on the bearing ring adjacent with inboard, through slider, stopper and first logical groove cooperation sliding connection between the adjacent bearing ring.

The principle and the technical effect of the scheme are as follows: bearing ring formula structure as an organic whole, the bearing ring of integral type is compared with the bearing ring that is formed by the mutual joint of a plurality of buckle pieces, and it is more convenient to install and dismantle, and the bearing capacity of flexible bench is stronger. The overall structure of slider and stopper is located the inboard of bearing ring, and the slider slides in the spout and the spacing inslot of intercommunication with the whole of stopper, and the buckle cooperation structure that the spout and the spacing groove of the whole and intercommunication of slider and stopper formed promptly is built-in, and the buckle cooperation structure of current flexible bench exposes and exists great potential safety hazard, if this cooperation structure exposes easily press from both sides and hinder user's finger, expose with buckle cooperation structure and compare, buckle cooperation structure embeds more beautifully and avoids pressing from both sides and hinder the finger, and is safer. The limiting blocks are used for limiting horizontal shaking between adjacent bearing rings.

When the telescopic stool in the fully compressed state needs to be unfolded in the height direction, a user pulls the stool plate upwards, and the bearing ring of the innermost layer and the stool plate synchronously move upwards. First logical groove on the bearing ring in intermediate level mutually supports with slider, the stopper on the bearing ring that the skin is adjacent, and the slider slides to the spacing inslot downwards by the spout that first logical groove is synchronous promptly with the stopper, the high increase of flexible bench, and highly by the restriction locking.
