Abstract

The utility model relates to a slideable chair, which comprises a seat surface, a backrest and chair legs, wherein, the upper ends of the chair legs are fixedly connected with the lower surface of the seat surface; the lower ends of the chair legs are fixedly connected with a wheel groove parallel to the seat surface; the wheel groove comprises an upper cover plate fixedly connected with the lower ends of the chair legs and side boards fixedly connected with both sides of the upper cover plate; hinge shafts are installed on the side boards of the wheel groove; each hinge shaft is sheathed with one end of a swing stem, and a roller is installed at the other end of each swing stem; each hinge shaft is sheathed with a torsion spring; and one end of each torsion spring is connected with the wheel groove, and the other end of each torsion spring is connected with each swing stem. The slideable chair can slide through the rollers on the chair legs when being moved, thereby achieving convenience and labor conservation, and the rollers are collected into the wheel groove when a user sits on the chair, so that the slideable chair is stable and cannot move at random; and the slideable chair has the advantages of simple structure and convenient use, and is especially suitable for being used in classrooms in middle and primary schools.

Description

Chair slidably

Technical field

The utility model relates to a kind of slidably chair.

Background technology

Be not with pulley on the common chair legs, require great effort very much in the time of mobile, especially for lower pupil, because strength is moved chair inadequately, usually chair is walked in tow; Have in addition a kind of under the chair of band pulley, very convenient in the time of mobile, but because pulley is fixed on the chair legs, and the pulley on the chair legs is stressed all the time, damage easily, chair also moved easily when seat was superincumbent, was not suitable for student classroom and used.

Summary of the invention

The purpose of this utility model provide a kind of easy to use, move flexibly, can not slide when sitting down, can be used for the slidably chair that student classroom uses.

For achieving the above object, the utility model is by the following technical solutions:

Slidably chair described in the utility model comprises seat surface, backrest, chair legs, the upper end of chair legs be fixedly connected on seat surface below, it is characterized in that: the lower end of chair legs is fixedly connected with race, described race and seat surface be arranged in parallel, race comprises the upper cover plate that is fixedly connected on the chair legs lower end, the side plate that is fixedly connected on the upper cover plate both sides, on the side plate of race hinge is installed, an end of fork is sleeved on the hinge, and the other end of fork is equipped with roller; Be set with torsion spring on hinge, an end of torsion spring is connected on the race, and the other end of torsion spring is connected on the fork.

After adopting technique scheme, this slidably chair when moving, can slide by the roller on the chair legs, convenient and strength-saving, roller takes in the race when sitting down, stable and can at will not move, simple in structure, easy to use, be particularly suitable for the students in middle and primary schools classroom and use.

Description of drawings

Accompanying drawing 1 is the structural representation of an embodiment of the utility model.

The specific embodiment

The utility model will be further described below in conjunction with the drawings and specific embodiments.

As shown in drawings, slidably chair described in the utility model comprises seat surface 1, backrest 2, chair legs 3, the upper end of chair legs 3 be fixedly connected on seat surface 1 below.The lower end of chair legs 3 is fixedly connected with race, described race and seat surface 1 be arranged in parallel, race 4 comprises the upper cover plate 41 that is fixedly connected on chair legs 3 lower ends, the side plate 42 that is fixedly connected on the upper cover plate both sides, on the side plate 42 of race, hinge 5 is installed, one end of fork 6 is sleeved on the hinge 5, the other end of fork 6 is equipped with roller 7, and described roller 7 can be a universal wheel, also can be the common pulley of installing by wheel shaft; Be set with torsion spring 8 on hinge 5, an end of torsion spring 8 is connected on the race, and the other end of torsion spring 8 is connected on the fork 6.

For the swing of giving fork 6 spacing, can also be on side plate 42, the extreme position fixed installation limited block 9 of fork 6 swings.

In order to keep balance, a plurality of forks 6 and roller 7 can be set in race.

When sitting the people on the chair, the gravity of people and chair addition is depressed torsion spring 8, and fork 6 swings to the position parallel with race, and roller 7 receives in the race that race directly contacts with ground, can avoid chair at will to move; After people's egress of chair, the gravity of human body disappears, and the weight that torsion spring 8 overcomes chair swings to extreme position with fork 6, is resisted against on the limited block 9, and this moment, roller 7 was stretched, and can promote chair and slide on the ground.
