Abstract

The utility model discloses a reversible public seat, which is characterized in that the center of the regular three-diamond column chair surface is provided with a rotational shaft; the same circle sticking out of the rotational shaft ends on the two sides of the regular three-diamond column chair surface is equally provided with three ratchet wheels; the same circle at the shaft hole ports of the two supporting frame are respectively equally provided with three pawls; the two ends of the rotational shaft is arranged between the two supporting frame; the three claws are buckled with the three ratchet wheels on the rotational axle; one end of the supporting post is arranged on a supporting frame; and the other end of the supporting post is provided with a backrest. The reversible regular three-diamond column chair surface is adopted and the ratchet wheel mechanism is used to realize the unilateral rotation of the chair surface. Such reversible structure can be used in the raining day by overturning the seat surface, thereby avoiding the case that no place can be found after raining. Meanwhile, application of the seat surface of different materials and different patterns present different feeling and different seat surface can be selected according to different taste and mood.

Description

The reversible public chair

Technical field

The utility model relates to seat, especially relates to a kind of reversible public chair.

Background technology

The public chair that present park etc. are outdoor is generally wooden or made of stones.And can not change to some extent with the conversion of environment, what sometimes just show is not to coordinate very much with environment.And, drench inconvenience at the back seat that rains and use.

Summary of the invention

For solve seat drench can not sit and with environment this two problems of getting along well, the purpose of this utility model is to provide a kind of reversible public chair.

The technical scheme that its technical problem that solves the utility model adopts is: comprise positive triangular prism seat, backrest, two bracing frames, rotating shaft, support bar, ratchet, holding screw and ratchets; Rotating shaft is equipped with at positive triangular prism seat center, the first-class branch of same circumference that stretches out the both sides rotating shaft end of positive triangular prism seat is equipped with three ratchets, on the same circumference of the axis hole port of two bracing frames, wait three ratchets of branch assembling respectively, the rotating shaft two ends are enclosed between two bracing frames, three ratchets in three ratchets and the rotating shaft are interlocked, one end of support bar is contained on the bracing frame, and the other end of support bar is equipped with backrest.

The beneficial effect that the utlity model has is:

Adopt turnover positive triangular prism seat, and realize that with ratchet mechanism the unidirectional rotation of seat, this turnover structure can climb over seat and continue to use after raining, do not have local situation of sitting after avoiding raining.Simultaneously, the application of unlike material and different pattern seat has different impressions, can select not coplanar seat according to difference hobby and mood.

The specific embodiment

As Fig. 1, Fig. 2, Fig. 3, shown in Figure 4, be contour structures schematic diagram of the present utility model.

As Fig. 5, Fig. 6, Fig. 7, shown in Figure 8, the utility model comprises positive triangular prism seat 1 (or multiaspect post seat), backrest 2, two bracing frames 3, rotating shaft 4, support bar 5, ratchet 6, holding screw 7 and ratchets 8; Rotating shaft 4 is equipped with at positive triangular prism seat 1 center, the first-class branch of same circumference that stretches out both sides rotating shaft 4 ends of positive triangular prism seat 1 is equipped with three ratchets 8, on the same circumference of the axis hole port of two bracing frames 3, wait three ratchets 6 of branch assembling respectively, on the ratchet 67 is holding screw, rotating shaft 4 two ends are enclosed within 3 of two bracing frames, three ratchets 6 are interlocked with three ratchets 8 in the rotating shaft 4, one end of support bar 5 is contained on the bracing frame 3, and the other end of support bar 5 is equipped with backrest 2 (being the triangle backrest among the figure).

This turnover structure can realize the unidirectional commutativity of seat, and guarantees to occupy stably, and climbs over seat and continue to use after raining, and does not have local situation of sitting after avoiding raining

The above-mentioned specific embodiment is used for the utility model of explaining; rather than the utility model limited; in the protection domain of spirit of the present utility model and claim, any modification and change to the utility model is made all fall into protection domain of the present utility model.
