Description

Technical Field

[0001] The utility model relates to the technical field of residential community landscapes, and specifically relates to a landscape spraying device for residential communities. Background Technique

[0002] With the improvement of the current living environment, the landscape construction in residential communities is also essential. It is necessary to maintain the landscapes inside the residential communities to ensure the humidity and quality of the landscape plants, so as to maintain a good environment in the landscape. At the same time, in the residential landscape area, it is necessary to spray the landscape to improve the greening and aesthetics of the landscape.

[0003] A landscape spraying device for urban residential communities disclosed in the prior art CN 214717781 U includes components such as a lifting mechanism, a box body, a main rod, a spray head, and a lamp post assembly. Although the lamp post assembly and the spray head of this utility model can extend or retract into the box body, reducing the damage to the lamp post assembly and the spray head and increasing their service life, after the spray head of this utility model is retracted into the box body, the upper part of the spray head is still in an open state. In this case, foreign impurities are likely to enter the interior of the outer box body and fall on the spray head, causing the spray head to be blocked, resulting in relatively frequent subsequent maintenance work, bringing many inconveniences to the normal use in the later stage, and also affecting the service life of the spray head. Moreover, when this utility model is telescoping, the edge of the box body will cause a certain degree of extrusion and scratching to the lamp post, which is likely to cause damage to the lamp post over time and result in a relatively low service life. Therefore, there is still room for improvement. Content of the Utility Model

[0026] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0027] The present invention provides Embodiment 1 of a landscape spray device for a residential community as shown in Figures 1 to 7 : An outer box body 1, a column body 2 and an atomizing nozzle 4. A soft water pipe 5 is arranged inside the outer box body 1. The upper end of the water pipe 5 is connected to the atomizing nozzle 4 by passing through the column body 2. The lower end of the water pipe 5 extends out of the outer box body 1 and is connected to an external water source to provide atomizing water source for the atomizing nozzle 4. The atomizing nozzle 4 is arranged at the upper end of the column body 2. The column body 2 is slidably installed inside the inner cavity of the outer box body 1. The inner cavity of the outer box body 1 is divided into a thick part and a thin part from bottom to top. The inner diameter of the thin part is the same as the outer diameter of the column body 2. An electric telescopic rod 3 for driving the column body 2 to slide is arranged inside the outer box body 1. An installation shell 12 is arranged on the upper side of the outer box body 1. An end cover 11 is arranged at the upper end opening of the outer box body 1. A sealing ring 1103 is arranged on the lower surface of the end cover 11. The sealing ring 1103 is inserted into the upper end opening of the outer box body 1. A convex plate 1101 is arranged on the outer side of the end cover 11. A first rotating shaft 1102 is arranged on the convex plate 1101. The convex plate 1101 is rotatably connected to the installation shell 12 through the first rotating shaft 1102. A tightening mechanism is arranged inside the installation shell 12. The tightening mechanism is respectively connected to the convex plate 1101 and the column body 2;

[0028] The top pressing mechanism includes a stop rod 13, a top rod 14 and a convex block 16. The stop rod 13 is slidably installed inside the mounting shell 12, and the upper end of the stop rod 13 abuts against the lower surface of the convex plate 1101. A second rotating shaft 15 is provided on the top rod 14, and the top rod 14 is rotatably installed in the mounting shell 12 through the second rotating shaft 15. The lower end of the stop rod 13 abuts against the top rod 14, and the stop rod 13 is located outside the first rotating shaft 1102 and the second rotating shaft 15. The convex block 16 is provided on the upper side of the column 2 and above the top rod 14, and the convex block 16 abuts against the side of the top rod 14 away from the stop rod 13. A stop block 17 is provided inside the mounting shell 12 below the convex plate 1101. A through groove 101 adapted to the convex block 16 is opened on one side of the upper part of the outer box body 1 close to the mounting shell 12. The convex block 16 is located inside the through groove 101, and one end of the top rod 14 close to the convex block 16 is located inside the through groove 101.

[0029] The initial state of the device is as Figures 1 to 3 shown. Both the column 2 and the atomizing nozzle 4 are located inside the outer box body 1. At this time, the end cover 11 covers the upper opening of the outer box body 1, and the sealing ring 1103 is inserted into the upper opening of the outer box body 1. At the same time, the convex block 16 presses down one end of the top rod 14, so that the other end of the top rod 14 presses up the stop rod 13, and the upper end of the stop rod 13 presses up the lower surface of the convex plate 1101, so that the convex plate 1101 and the end cover 11 can be fixed to the upper end of the outer box body 1, specifically as Figure 2 shown. Therefore, the end cover 11 and the sealing ring 1103 can seal the upper opening of the outer box body 1 and effectively prevent external impurities from falling into the outer box body 1 from the upper opening of the outer box body 1;

[0030] When the atomizing nozzle 4 needs to be extended, control the telescopic end of the electric telescopic rod 3 to extend upward and push the column 2 and the atomizing nozzle 4 to slide upward along the outer box body 1 by a certain distance. During this process, the convex block 16 will separate from the top rod 14. Therefore, the downward pressing limit of the convex block 16 on the second rotating shaft 15 disappears, and the upward pressing limit of the top rod 14 on the stop rod 13 and the upward pressing limit of the stop rod 13 on the convex plate 1101 also disappear. Therefore, until the atomizing nozzle 4 contacts the end cover 11, the continuous upward movement of the atomizing nozzle 4 can push the end cover 11 upward, so that the atomizing nozzle 4 and the convex plate 1101 rotate clockwise around the axis of the first rotating shaft 1102. Then the atomizing nozzle 4 continues to move upward until it completely extends out of the outer box body 1, and the stop block 17 will also block and limit the rotating convex plate 1101, so that the end cover 11 stops rotating. At this time, the rotation angle of the end cover 11 is less than 90°, specifically as Figure 6 shown. Moreover, under the action of gravity, the stop rod 13 slides down a certain distance and presses down the top rod 14 to rotate clockwise around the second rotating shaft 15;

[0031] When it is necessary to retract the atomizing nozzle 4 into the outer box body 1, control the telescopic end of the electric telescopic rod 3 to contract downward to the original position, and the column 2 and the atomizing nozzle 4 can be pulled back into the outer box body 1. Moreover, during this process, when the atomizing nozzle 4 slides past the end cover 11, at this time, the end cover 11 rotates counterclockwise downward under the action of gravity and returns to the upper end of the outer box body 1, and as the column 2 continues to slide down, the convex block 16 can press down the ejector rod 14, causing the ejector rod 14 to rotate counterclockwise back to the original position. The other end of the ejector rod 14 pushes the blocking rod 13 upward back to the original position, so that the blocking rod 13 abuts against the lower surface of the convex plate 1101, thereby fixing the end cover 11 and the convex plate 1101, achieving the purpose of automatically sealing the upper end of the outer box body 1.

[0032] The present utility model provides an embodiment 2 of a residential community landscape spraying device as Figure 1 and Figure 3 as well as Figures 5 to 7 shown: A limiting ring 10 is provided at the lower part of the column 2. The limiting ring 10 is slidably installed in the inner cavity of the thick part of the outer box body 1. A folding groove 201 is formed on the outer surface of the column 2. A lamp post assembly is arranged inside the folding groove 201. The lamp post assembly includes two lamp posts 6 hinged to each other. The upper end of the lamp post 6 located at the upper part is connected to the folding groove 201. An ejecting assembly is arranged between the lower end of the lamp post assembly and the telescopic end of the electric telescopic rod 3. The ejecting assembly includes a connecting rod 7, a connecting plate 8 and a return spring 9. The connecting rod 7 is slidably installed on the column 2 along the length direction, and the upper end of the connecting rod 7 is hinged to the lower end of the lamp post 6 located at the lower part. The connecting plate 8 is fixedly installed at the lower end of the connecting rod 7 and is located below the column 2, and the connecting plate 8 is fixed to the telescopic end of the electric telescopic rod 3. The return spring 9 is connected between the connecting plate 8 and the column 2.

[0033] When the atomizing nozzle 4 is extended upward, the telescopic end of the electric telescopic rod 3 extends upward and pushes the connecting plate 8 to slide. The connecting plate 8 then pushes the column 2 to slide upward through the return spring 9, so as to extend the column 2 and the atomizing nozzle 4 upward. At the same time, the limiting ring 10 slides synchronously with the column 2. During this process, under the action of the elastic force of the return spring 9, the connecting plate 8 and the column 2 will not slide relative to each other until the limiting ring 10 abuts against the lower end of the thin part of the inner cavity of the outer box body 1. Under its restriction, the column 2 stops extending upward. At this time, the column 2 and the atomizing nozzle 4 just extend to the preset position. Then, the telescopic end of the electric telescopic rod 3 will continue to extend upward by a certain distance, and thereby push the connecting plate 8 and the connecting rod 7 to continue to move upward. At this time, the connecting plate 8 and the column 2 will compress the return spring 9, and the upward moving connecting rod 7 can push the lower lamp post 6, and under this pushing force, the two hinged lamp posts 6 can rotate relative to each other and expand outward, so that the lamp posts 6 are expanded outward after the column 2 extends out of the outer box body 1. Therefore, it is possible to avoid extrusion and scratching between the lamp posts 6 and the outer box body 1 during the extension process.

[0034] Moreover, when the cylinder 2 is retracted downward back into the outer box body 1, since the return spring 9 was compressed previously, when the retracting end of the electric telescopic rod 3 retracts, the return spring 9 will first push the connecting plate 8 and the connecting rod 7 to slide downward on the cylinder 2, while the cylinder 2 remains stationary. Therefore, under the pulling of the connecting rod 7, the two lamp poles 6 will fold back into the folding groove 201 until the return spring 9 expands to its original length and then the cylinder 2 begins to slowly slide down and contract. Thus, it can be ensured that the lamp poles 6 can be automatically folded back into the folding groove 201 before the cylinder 2 contracts, so as to avoid extrusion and scratching between the lamp poles 6 and the outer box body 1 during the contraction process.

[0035] The above is only a preferred specific embodiment of the present invention, but the protection scope of the present invention is not limited thereto. Any person skilled in the art within the technical scope disclosed by the present invention, according to the technical solution of the present invention and its inventive concept, makes equivalent replacements or changes, and all should be covered within the protection scope of the present invention.
