Abstract

The invention discloses a rotary backrest for reducing the pollution of a suburban stone bench, and the rotary backrest relates to the field of the cleaning of suburban stone benches, in particular to the field of covered cleaning. Due to the impact of guano, water drops of plants around, dust and the like, the surfaces of the stone benches in parks and other places are quite dirty after a long time. In order to better keep the surface of the stone bench clean, the invention design a backrest to cover the stone bench. The technical scheme is that the stone bench is provided with the rotary backrest; when the backrest rotates to an upright state, the backrest plays the role of a common backrest; and when the backrest rotates to a horizontal state, the backrest covers the surface of the stone bench and serves as a stone bench cover. The rotary backrest for reducing the pollution of the suburban stone bench has the beneficial effects that the pollution of the environment dust and the guano is reduced, the impact of rest water trace of the water drops of leaves is reduced, so that the bench is cleaner and more attractive, and is not disgusting.

Description

Reduce the rotary backrest that countryside stone bench pollutes

Technical field

The present invention relates to countryside stone bench field, the particularly covering type of the countryside stone bench aspect of keeping a public place clean of keeping a public place clean.

Background technology

In order to make visitor have the place of rest, in places such as park, schools, there is stone bench, due to stone bench surface exposure, cause the leaf of birds droppings, surrounding plants to drip, the impact such as dust, of long duration after, its surface seems messy, few people dare to sit, and also just run counter to the original intention that stone bench is set.

Summary of the invention

In order to keep better the clean of stone bench surface, the present invention designs a rotary backrest stone bench surface is covered.

The technical scheme that the present invention realizes goal of the invention employing is: stone bench has a rotary backrest, when backrest rotates to erectility, makes backrest and uses; When backrest rotates to level, backrest, by stone bench shaded surface, is made stone bench cover and is used.

The rotary backrest of stone bench, main appurtenances have position of rest, bracing frame, cushion pad, rolling bearing, connecting rod.

Backrest is comprised of panel, through hole and baffle plate, and the shape of backrest is roughly consistent with stone bench surface configuration, and most stone bench is circular, so panel is mainly circular slab.

The rotation of backrest is to complete by rolling bearing, and a Metallic rod is passed through two through holes of bracing frame through hole and backrest, and Metallic rod is fixed by screw thread and nut at bracing frame two ends, arranges that rolling bearing is connected with Metallic rod in backrest through hole.

Bracing frame is cuboid, thickness 10cm, and long 15-20cm, high 15-20cm, material is cement, and there is position of rest at bracing frame rear portion, and support column is arranged at bracing frame bottom; Or bracing frame and support column become one.

When backrest keeps flat, the baffle plate of backrest touches position of rest, and at this moment the circular slab of backrest covers the upper surface of stone bench, and backrest edge is than the long 3-5cm in stone bench edge, stone bench surface distance back panel 1-2cm, can reduce the invasion and attack of pollutant to stone bench surface such as birds droppings, dust.

When backrest is upright, the baffle plate contact stone bench cushion pad of backrest, back cushion pad before the back side contact bracing frame of back panel, back panel consists of circular slab conventionally, for increasing bottom width, conventionally in bottom, connect a rectangular slab, circular slab and rectangular slab are shaped to integrative-structure, people is sitting on stone bench and feels happier.

The invention has the beneficial effects as follows: reduce the pollution of ambient dust and birds droppings, reduce the impact of leaf water droplet residual water mark, make stool more clean attractive in appearance, make people not disagreeable.

Accompanying drawing explanation

Fig. 1 is the antipollution rotary backrest schematic diagram of countryside stone bench.

Wherein, 1, position of rest, 2, bracing frame, 3, back cushion pad, 4, fixture, 5, support column, 6, joint pin, 7, backrest, 8, stone bench cushion pad, 9, stone bench, 10, circular slab, 11, rectangular slab, 12, through hole, 13, baffle plate.

The specific embodiment

The panel that reduces the backrest 7 of stone bench pollution is comprised of circular slab 10 and rectangular slab 11.Below backrest, have a rectangular opening, there is respectively a through hole 12 on rectangular opening both sides, by the through hole of this through hole 12 and bracing frame 2, utilize fixture 4 that backrest is fixed on bracing frame 2.

Fixture 4 is through the Metallic rod of bracing frame through hole and is fixed on the rolling bearing composition in backrest 7 through holes 12, the axle that Metallic rod is rolling bearing, and this axle maintains static.

Support column 5 is arranged at bracing frame 2 bottoms, and there is position of rest 1 at rear portion, and when backrest 7 keeps flat, the baffle plate 13 of backrest 7 touches position of rest 1, and at this moment the circular slab 10 of backrest covers the upper surface of stone bench 9, can reduce the invasion and attack of the pollutants such as birds droppings to stone bench surface.

When backrest is upright, the baffle plate of backrest 13 contact stone bench cushion pads 8, the rectangular slab 11 contact bracing frames 2 back cushion pad 3 above of backrest, circular slab 10 and rectangular slab 11 actings in conjunction, be equivalent to the backrest of chair, people is sitting on chair and feels happier.

Bracing frame 2 is connected by cement joint pin 6 with stone bench 9, strengthens intensity each other.

Claims

1. reduce the rotary backrest that countryside stone bench pollutes, when backrest rotates to erectility, the backrest that back panel is made stone bench is used; When backrest rotates to level, back panel, by stone bench shaded surface, is made stone bench cover and is used, and it is characterized in that: the rotary backrest of stone bench, and main appurtenances have position of rest, bracing frame, cushion pad, rolling bearing, joint pin; The rotation of backrest is to complete by rolling bearing, and a Metallic rod is passed through two through holes of bracing frame through hole and backrest, and Metallic rod is fixed on bracing frame both sides by screw thread and the nut at two ends, arranges that rolling bearing is connected with Metallic rod in backrest through hole; When backrest keeps flat, the baffle plate of backrest touches position of rest, and at this moment the panel of backrest covers the surface of stone bench, and the edge of back panel is than the long 3-5cm in stone bench edge, stone bench surface distance back panel 1-2cm; When backrest is upright, the baffle plate of backrest contact stone bench cushion pad, back panel rear surface contacts the back cushion pad before bracing frame; A cement joint pin connects backrest and stone bench.
