Description

Technical Field

[0001] The invention relates to the technical field of waterscape gallery, in particular to a waterscape gallery based on a landscape road. Background Art

[0002] The pergola is a garden building, which is made of antiseptic wood, bamboo, stone, metal, and reinforced concrete as the main raw materials and other materials added to it. It is a building for tourists to rest and embellish the landscape, and it is very harmonious with the natural ecological environment. The pergola, with its natural and realistic performance, adds a strong cultural atmosphere to squares, parks, and communities. The pergola can be used in various types of gardens and green spaces. It is often set up in scenic places for rest and scenery. It can also be combined with pavilions, corridors, waterside pavilions, etc. to form a beautiful garden building complex; in residential green spaces and children's playgrounds, pergolas can be used for rest, shade, and coolness; using pergolas instead of corridors can connect spaces; using lattice walls to climb vines can separate scenery; tea rooms, cold drink shops, restaurants, etc. in the garden can also use pergolas as pergolas and set up seats; pergolas can also be used as garden gates;

[0003] When the waterscape pergola is in use, a concrete foundation is usually used as the base of the pergola, which makes it inconvenient to dismantle or install the waterscape pergola, increasing the workload of dismantling or installing the waterscape pergola. At the same time, when the waterscape pergola is in use, passengers cannot shield the top of the pergola according to weather changes, resulting in a low utilization rate of the pergola in bad weather. It is inconvenient to collect rainwater in bad weather, which increases the cleaning cost when flushing the pergola. Summary of the invention

[0004] 1. Technical issues to be resolved

[0005] In view of the shortcomings of the prior art, the present invention provides a waterscape gallery based on a landscape road, wherein the support column is pushed downward so that the support column can slide on the surface of the gallery column. When the support column continues to move downward, the support column can drive the insertion rod, the first thorn rod and the second thorn rod to move downward, and the mounting plate is stepped on so that the insertion rod can be completely inserted into the soil, and the sliding of the adjustment plate and the hollow plate can be used to pull the adjustment plate to one side, and the adjustment plate can be extended from the inside of the hollow plate. The first thorn rod is used to be tilted and inserted into the soil, and the second thorn rod can be inserted into the soil following the movement of the support column to improve the stability of the first thorn rod when it is tilted and inserted. At the same time, the extension of the adjustment plate can be used to increase the contact area between the support and the soil. When the support is fixed, the push plate is pushed to one side so that the concave block can be embedded with the gallery column, and the wear-resistant block can fit with the surface of the gallery column so that it can increase the friction between the concave block and the gallery column, thereby fixing the gallery column. After the concave block is embedded with the gallery column, the limit plate is embedded in the specified groove so that the magnet can fit with the surface of the support to attract each other to fix the push plate, thereby The waterscape gallery is highly stable during installation and use. Hold the handle so that the sunshade and the frame can be pushed by the support plate to move. Before using the waterscape gallery, the staff needs to add lubricating oil to the inside of the sliding seat in advance so that the absorbent cotton can absorb the lubricating oil in the sliding seat. When people push the sunshade and the frame to move, the slider can slide inside the sliding seat. When the slider slides, it can drive the ball roller to slide on the surface of the flat plate. When the slider, ball and roller are sliding, the absorbent cotton can adhere to the surface of the slider, ball and roller. The fit allows the absorbent cotton to wipe the lubricating oil on the surface of the slider, ball and roller, which can reduce the friction when the slider, ball and roller roll, so that the sun visor and the frame can move faster. In bad weather, the sun visor can be used to collect rainwater, and the support plate can be pushed upward. By utilizing the movement of the movable rod and the frame, one side of the sun visor can use the movable rod as the center of the circle, and the other side can be swung upward so that the sun visor can be tilted to discharge rainwater to wash the waterscape gallery, thereby saving the cleaning cost of the waterscape gallery and other advantages.

When people push the sunshade and the frame to move, the slider can slide inside the sliding seat, and the slider can drive the ball roller to slide on the surface of the flat plate together when sliding. When the slider, the ball and the roller are sliding, the absorbent cotton can fit with the surface of the slider, the ball and the roller, so that the absorbent cotton can wipe the lubricating oil on the surface of the slider, the ball and the roller, so that the slider, the ball and the roller can reduce the friction when rolling, thereby making the sunshade and the frame move faster. In bad weather, the sunshade can be used to collect rainwater, and the support plate is pushed upward. By utilizing the activity of the movable rod and the frame, one side of the sunshade can be used as the movable rod as the center of the circle, and the other side can be swung upward so that the sunshade can be tilted to discharge rainwater to wash the waterscape gallery, thereby saving the cleaning cost of the waterscape gallery.
