Description

A kind of telescopic bench

Technical field

The utility model relates to a kind of bench, relates in particular to a kind of telescopic bench.

Background technology

Be located at the public arena at present and make things convenient for passerby to stop the bench of rest, its length is all fixed, and carrying fewer in number will increase the carrying number and then must increase length, and its floor space also increases thereupon.And the operating position of bench has its particularity, what need generally speaking to carry simultaneously is fewer in number, usually all be companion's 2-3 people, the concentrated growth of the number that need carry simultaneously just just can occur in some special time period or period, the method that therefore increase length muchly in order to satisfy provisional needs, increases floor space is worthless.

The utility model content

At the problem that above-mentioned prior art exists, the utility model purpose is to provide a kind of telescopic bench, and it uses length to adjust flexibly, reaches the balance of occupation of land and bearing capacity.

The technical solution of the utility model is: a kind of telescopic bench, the seat that comprises strip, described seat one end is provided with the first chair leg, the seat below also is laminated with second, third seat, is positioned at second seat, one end and the seat switching in middle level, and this end lower surface is provided with the second chair leg, the other end and the switching of the 3rd seat, three seats all can horizontally rotate mutually around the shaft, and the 3rd seat two ends also are provided with the 3rd chair leg, all contact to earth in first, second and third chair leg bottom.

As preferably, described first, second and third chair leg is a cuboid plate.

The beneficial effects of the utility model are: under the general case, seat can satisfy the demand of bearing capacity, when needing to increase bearing capacity temporarily, can rotate second seat and pull it, length nearly doubles thereupon, bearing capacity also increases nearly one times, pull it as further rotation the 3rd seat, length increases nearly twice thereupon, and bearing capacity also increases nearly twice, use length to adjust flexibly, reach the balance of occupation of land and bearing capacity with demand.
