detailed description

Below in conjunction with specific accompanying drawing and embodiment the utility model is further described.

As shown in Figures 1, 2, 3, 5, 6, and 7, a buried automatic lifting sprinkler head with adjustable spraying area and range includes a casing 9 and a sealing cover 2 that is threaded at the top, installed on the The telescopic tube 5 inside the casing 2 also includes a spray head 1 connected to the top of the telescopic tube 5 , and the spray head 1 includes a refracting cone 102 , an adjusting screw cap 103 , an adjusting bolt 101 and a spray head base 104 .

The refraction cone 102 and the nozzle base 104 are snap-fit connections, the adjusting screw cap 103 is interposed between the refraction cone 102 and the nozzle base 104 and is threadedly connected to the nozzle base 104, and the nozzle base 104 is connected to the telescopic tube 5 On the top end, the adjusting bolt 101 passes through the middle of the refracting cone 102 , the adjusting screw cap 103 , and the nozzle base 104 .

The inner side of the lower end of the nozzle base 104 is threadedly connected to the outer top of the telescopic tube 5 , and the upper end of the telescopic tube 5 is fixedly connected to a cylindrical filter 4 . As shown in Figure 4, the upper part of the refraction cone 102 is trumpet-shaped, the lower part is cylindrical, the side wall of the upper part is a single-turn spiral structure with no less than 2, the lower part is provided with buckles on the outside and the inner wall is provided with There are threads.

The upper end of the adjusting screw cap 103 is provided with a single-turn spiral "slope" structure matching the upper part of the side wall of the refraction cone 102, and a stopper is provided at the top. The adjusting bolt 101 is threadedly connected to the refracting cone 102 , the head of the adjusting bolt 101 is downward, the screw rod is upward and has a "one" screw opening. The lower end of the telescopic tube 5 is sleeved with a connecting tube, and the outside of the connecting tube 5 is sleeved with a spring 7 .

A through hole for the telescopic tube 5 to enter and exit is opened in the center of the sealing cover 2 , and a sealing ring 3 is provided on the side wall of the through hole. The inner side of the housing 9 is provided with a grooved track. The bottom of the telescopic tube 5 is buckled to a positioning ring 8 , as shown in FIG. 6 , the positioning ring 8 is provided with a protrusion 81 matching the groove track.

The utility model work process is as follows:

As shown in Figures 1, 2, and 3, the casing 9 is connected to the water source. When the water source is turned off, the telescopic tube 5 and the nozzle 1 are inside the casing 9. The telescopic tube 5 and the nozzle 1 are not easily damaged and will not affect the garden. The beauty of the greenery.

After the water source is turned on, water enters the housing 9, and the water pressure in the housing 9 rises, and can push the telescopic tube 5 and the nozzle 1 to rise. The lower end of the telescopic tube 5 is sleeved with a spring 7, and the positioning ring 8 and the telescopic tube 5 are snap-fitted. , when the water pressure is high, the telescopic tube 5 rises steadily along the groove tracks on both sides of the pipe in the casing 9 through the protrusions on both sides of the positioning ring 8, so that the telescopic tube 5 does not shake and maintain Vertical, non-tilted, and non-rotatable. When the telescopic tube 5 rises to the top of the housing 9, the top of the spring 7 socketed by the telescopic tube 5 touches the sealing cover 2, and the spring 7 acts as a buffer through the active force and the reaction force, even if the telescopic tube 5 is under water pressure. When it suddenly increases, it is not easy to collide with the sealing cover 2, so as to avoid the occurrence of noise or damage. Under the action of water pressure, the telescopic tube 5 rises to the top of the housing 9, and under the action of the sealing cover 2, the sealing ring 3 and the connecting pipe 6, the sealing of the connection between the telescopic tube 5 and the housing 9 is ensured, and no leakage occurs. Leaks to keep the water pressure steady. When the water pressure is stable, the water source passes through the telescopic tube 5 and enters the cylindrical filter 4 installed in the telescopic tube 5. After filtering, it can prevent the particles or debris in the water source from blocking the nozzle 1. The filtered water source passes through the nozzle. After the base 104 and the screw cap 103 are adjusted, the water source is sprayed outward under the action of the refraction cone 102 .

The inner wall of the lower part of the refracting cone 102 is threadedly connected to the adjusting bolt 101. The head of the adjusting bolt 101 is downward, and the screw rod is upward and is provided with a "one" screw hole. Turn the "one" screw hole to make the adjusting bolt 101 rotate. When the adjusting bolt When 101 rotates downwards, its head is close to the water outlet above the cylindrical filter screen 4, the outlet area becomes smaller, and the flow at the outlet decreases accordingly. , the outlet pressure of the nozzle 1 decreases, and the range of the nozzle 1 becomes shorter. When the head of the adjusting bolt 101 is far away from the water outlet of the cylindrical filter 4, the outlet area increases, the flow rate increases, the outlet pressure of the nozzle 1 rises, and the range becomes longer. . By changing the distance between the head of the adjusting bolt 101 and the water outlet of the cylindrical filter 4 , the flow rate can be changed to realize the adjustment of the shooting range of the spray head 1 .

As shown in Figure 4, the upper end of the adjusting screw cap 103 is a single-turn spiral "slope" structure, and is provided with a stopper 1031. In cooperation, the spray fan-shaped area of the spray head 1 can be changed by adjusting the gap between the screw cap 103 and the refraction cone 102 by adopting the principle of screw connection. When the distance between the head of the adjustment bolt 101 and the water outlet of the cylindrical filter 4 is constant, and the range is constant, the rotation adjustment screw cap 103 is close to the refraction cone 102, and the gap between them becomes smaller, thereby changing the spray outlet area and spraying the fan. The area becomes smaller; when the screw cap 103 is adjusted away from the refraction cone 102, the gap becomes larger, the area of the spray outlet becomes larger, and the area of the spray fan becomes larger.

When the housing 9 stops water intake or the water pressure is too low, the telescopic tube 5 and the nozzle 1 reset automatically under the action of the spring 7 and gravity, and descend into the pipeline of the housing 9 .

The utility model can also have other various embodiments. Without departing from the spirit and essence of the utility model, it is possible to improve, increase and replace the structure, shape and connection mode of each component. Equivalent changes or improvements made on the basis of the new technical solution shall not be excluded from the protection scope of the present utility model.
