Description

Technical Field

[0001] This utility model relates to the field of buried telescopic sprinkler pipes, and in particular to a snap-fit ​​segmented connection device for buried telescopic sprinkler pipes. Background Technology

[0002] Buried telescopic sprinkler pipes combine traditional fixed-length irrigation pipes with a telescopic structure. These pipes are typically made of high-strength, corrosion-resistant materials, enabling long-term stable use in underground environments. Under normal conditions, the pipe is buried underground. When irrigation is needed, the pipe can be extended or retracted via water pressure or mechanical control, allowing the sprinkler heads to extend above ground for spraying. After irrigation, the sprinkler heads and pipes retract underground, avoiding disruption to surface agricultural activities and machinery operations, and reducing the risk of human-caused damage to the pipeline.

[0003] Buried telescopic sprinkler pipes are widely used in modern agriculture and landscaping. Currently, different sections of buried telescopic sprinkler pipes need to be connected and assembled. However, existing connection devices are complicated to install, requiring specialized tools and highly skilled installers. Furthermore, in terms of later maintenance, if a connection fails, the disassembly and replacement process is cumbersome and does not achieve the effect of quick assembly and disassembly. Therefore, we propose a snap-fit ​​segmented connection device for buried telescopic sprinkler pipes to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide a snap-fit ​​segmented connection device for buried telescopic sprinkler pipes to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A snap-fit ​​segmented connection device for a buried telescopic sprinkler pipe includes a buried pipe, a lower telescopic pipe inside the buried pipe, and an upper telescopic pipe above the lower telescopic pipe.

The bottom end of the connecting sleeve passes through the annular locking spring and extends below it. A sealing ring is fixedly connected to the inner ring of the lower telescopic pipe. The inner rings of both the annular locking spring and the sealing ring are in close contact with the outer surface of the connecting sleeve. An annular sealing recess is fixedly connected to the inner ring of the lower telescopic pipe, and a sealing plate is fixedly connected to the inner wall of the annular sealing recess. The upper surface of the sealing plate is in close contact with the bottom end of the upper telescopic pipe.

[0007] In a further embodiment, a limiting ring is fixedly connected to the inner ring of the lower telescopic tube, the outer surface of the limiting ring is slidably connected to the inner ring of the buried pipe, and a first sealing gasket is fixedly connected to the inner top wall of the buried pipe, the first sealing gasket being located above the limiting ring.

[0008] In a further embodiment, the top end of the buried pipe is provided with a telescopic hole, and the lower telescopic pipe is located inside the telescopic hole.

[0009] In a further embodiment, the inner ring of the buried pipe is fixedly connected to a lower annular protrusion, the bottom surface of the lower annular protrusion is fixedly connected to a second sealing gasket, the inner ring of the upper telescopic pipe is fixedly connected to an upper annular protrusion, and the upper surface of the upper annular protrusion is fixedly connected to a third sealing gasket.

[0010] In a further embodiment, the lower telescopic tube is provided with a release sleeve inside, the release sleeve is located above the annular locking spring, and the outer surface of the upper telescopic tube is provided with a plurality of anti-slip recesses.

[0011] In a further embodiment, a nozzle is threadedly connected to the inner ring of the top end of the upper telescopic tube, and the nozzle is located above the third sealing gasket.

[0012] Compared with the prior art, the beneficial effects of this utility model are:

[0013] This invention uses a connecting sleeve inserted into the lower telescopic tube and the elastic locking force of the annular locking spring to lock the connecting sleeve, allowing the upper and lower telescopic tubes to be quickly snapped together. Furthermore, the sealing ring, annular sealing recess, and sealing sheet seal the connection between the upper and lower telescopic tubes, preventing leakage. During disassembly, pressing down on the release sleeve releases the annular locking spring, facilitating the upward pulling of the upper telescopic tube for disassembly and improving the flexibility of assembling and disassembling the upper telescopic tube.

Through the cooperation of the lower annular protrusion 15 and the second sealing gasket 16 with the upper annular protrusion 13 and the third sealing gasket 14, the sealing performance of the entire connection device is enhanced. By setting the nozzle 18, irrigation water will be sprayed efficiently through the nozzle 18 to meet the irrigation needs of different scenarios.

[0023] The working principle of this utility model is as follows: When the upper telescopic tube 3 and the lower telescopic tube 2 are connected, the connecting sleeve 7 at the bottom of the upper telescopic tube 3 is first inserted into the interior of the lower telescopic tube 2. The connecting sleeve 7 can be locked by the annular locking spring 9 to achieve a quick snap-fit ​​connection. Then, the connection between the upper telescopic tube 3 and the lower telescopic tube 2 can be sealed by the tight cooperation of the sealing ring 10, the annular sealing recess 8 and the sealing sheet 12. During maintenance, the sliding sleeve 11 is pressed down to release the locking of the annular locking spring 9. Then, the upper telescopic tube 3 can be disassembled and replaced by pulling it upward.
