Description

[Technical Field]

[0001] This utility model relates to the field of manual operation tool processing technology, and in particular to a manual operation tool for removing and replacing sprinkler heads in underground water supply systems. [Background Technology]

[0002] Subsurface irrigation systems are typically used to precisely and controllably spray water onto lawns. Such systems consist of plastic supply pipes installed beneath the lawn. Because the sprinklers or drip tubes of subsurface irrigation systems are buried in the soil for extended periods, their perforations are prone to clogging by silt, organic matter, or chemical deposits, leading to reduced irrigation efficiency. Furthermore, the concealed location of subsurface sprinklers makes routine maintenance difficult.

[0003] Sprinkler heads are typically composed of a cylindrical plastic casing, with shapes primarily including diffuser, swirling, and jet stream types, and diameters ranging from 6mm (nozzle) to 57mm (exposed top portion). Different designs cater to diverse irrigation needs. In practical applications, users often need to select different sprinkler types based on the irrigation area, terrain complexity, and water quality conditions. When removing sprinklers, it is necessary to find the appropriate removal tools for each type.

[0004] In the existing technology, the tools for removing the nozzles are only compatible with a single nozzle model, requiring multiple sets of tools, which results in high costs, cumbersome operation, and great inconvenience for users. [Utility Model Content]

[0005] This invention provides a manual operation tool for solving the aforementioned background problems.

[0006] This utility model provides a manual operating tool for removing and replacing sprinkler heads in an underground water supply system. It includes a first pipe fitting, a handle, and a first component. The first pipe fitting includes a first wall surface and a first protruding ridge. The first wall surface forms a cylindrical structure with openings at both ends. At least one of the first protruding ridges is disposed on at least a portion of the first wall surface. The handle includes a mounting portion and a gripping portion. The mounting portion has a first mounting hole and a first limiting hole. The first limiting hole is disposed around the first mounting hole, corresponding to the openings. The first limiting hole corresponds to at least one of the protruding ridges. The gripping portion is connected to the mounting portion. The first component is detachably connected to the first pipe fitting and firmly attached to the sprinkler head to rotate and lift the sprinkler head.

[0007] Compared with the prior art, the manual operating tool provided by this utility model can be used to disassemble and replace the sprinkler heads of underground water supply systems. By setting a detachable first pipe and a first component, the first component can be firmly connected to the sprinkler head. The force applied by the handle can rotate and lift the sprinkler head. When it is necessary to remove different models of sprinkler heads, simply replace the first component, insert the remaining components into the opening of the first pipe, and tighten them for installation. Other models of sprinkler heads can be removed. The operation is simple and convenient. [Attached Image Description]

[0041] Please refer to the following: Figures 1 to 5 , Figure 1 This is a three-dimensional structural diagram of the first embodiment of the manual operating tool provided by this utility model from a first angle. Figure 2 This is a two-dimensional structural diagram of the first embodiment of the manual operating tool provided by this utility model from a second angle; Figure 3 This is an exploded perspective view of the first embodiment of the manual operating tool provided by this utility model.

[0042] In a first embodiment, the present invention provides a manual operating tool for removing and replacing nozzles of an underground water supply system. The manual operating tool includes a first pipe fitting 10 of integral construction, a second pipe fitting 20 of integral construction, a handle 30, and a first component 40. The handle 30, the first pipe fitting 10, the second pipe fitting 20, and the first component 40 are detachably connected for easy assembly and carrying.

[0043] The first pipe fitting 10 includes a first wall surface 101 and a plurality of first protruding ribs 102. The first wall surface 101 forms a cylindrical structure with openings at both ends, which facilitates disassembly or assembly of other components by the user through the openings. The first wall surface 101 includes a first arc surface 1011 and a second arc surface 1012. The second arc surface 1012 smoothly connects to the first arc surface 1011. The first arc surface 1011 forms a first region 1011A of the first pipe fitting 10, and the second arc surface 1012 forms a second region 1012A of the first pipe fitting 10. The second region 1012A smoothly connects to the first region 1011A to form the first wall surface 101. The cross-sectional area of ​​the second region 1012A is smaller than that of the first region 1011A. The first region 1011A with a larger cross-sectional area is used to match the size of the mounting portion 301 of the handle 30, providing a wrap-around contact surface to prevent the first pipe fitting 10 from shaking when the user rotates the handle 30. The second section 1012A with a smaller cross-sectional area is used to insert the second tube 20, which tightly clamps the first component 40.

[0044] Multiple first protruding ridges 102 are disposed on the outer surface of the first wall 101, and the first protruding ridges 102 extend along the first region 1011A to the second region 1012A, forming a continuous stress transmission channel to evenly distribute the torque of the handle 30 to the entire section from the second pipe to the nozzle.

[0045] It is understood that the number of the first protruding ribs 102 is not limited. In this embodiment, the first protruding ribs 102 are divided into four segments. The four segments of the first protruding ribs 102 are symmetrically arranged on the outer surface of the first wall 101. The first protruding ribs 102 extend along the first region 1011A to the second region 1012A. The first protruding ribs 102 are arranged in a stepped shape. The height of the first protruding ribs 102 decreases with each segment to ensure that one end of the first tube 10 can be nested in the handle 30 and the other end of the first tube 10 can be nested in the second tube 20. This achieves that while the first tube 10 and the handle 30 are nested and locked together, the first tube 10 can also be nested and locked together with the second tube 20.

[0046] The handle 30 includes a mounting part 301 and a gripping part 302. The mounting part 301 is provided with a first mounting hole 3011 and a first limiting hole 3012. The first limiting hole 3012 is disposed around the first mounting hole 3011. The first mounting hole 3011 is corresponding to the opening. The first limiting hole 3012 is corresponding to at least one first protruding ridge 102. When installing the handle 30, the first mounting hole 3011 is aligned with the opening of the first pipe fitting 10 adjacent to the first area 1011A, and the first limiting hole 3012 is aligned with the first protruding ridge 102 of the first pipe fitting 10, ensuring that the handle 30 and the axis of the first pipe fitting 10 are strictly aligned. After actual measurement, the assembly time of the first pipe fitting 10 and the handle 30 is reduced from 2 minutes required for traditional bolt hole alignment to 5 seconds, and limiting and locking can be achieved.

[0047] The second pipe fitting 20 includes a second wall surface 201 and a plurality of second protruding ribs 202. The second wall surface 201 forms a cylindrical structure with openings at both ends. The second wall surface 201 includes a third arc surface 2011, a fourth arc surface 2012, a fifth arc surface 2013, a sixth arc surface 2014, and a seventh arc surface 2015 connected in a stepped manner. The third arc surface 2011 forms a third region 2011A of the second wall surface 201. The fourth arc surface 2012 forms a fourth region 2012A of the second wall surface 201. The fifth arc surface 2013 forms a fifth region 2013A of the second wall surface 201. The sixth arc surface 2014 forms a sixth region 2014A of the second wall surface 201. The seventh arc surface 2015 forms a seventh region 2015A of the second wall surface 201. The cross-sectional areas of the third zone 2011A, fourth zone 2012A, fifth zone 2013A, sixth zone 2014A, and seventh zone 2015A decrease sequentially, forming a continuous diameter-reducing structure. Each of the third zone 2011A, fourth zone 2012A, fifth zone 2013A, sixth zone 2014A, and seventh zone 2015A is provided with the second protruding ridge 202.

[0048] It is understood that the number of the second protruding ribs 202 is not limited. In this embodiment, the second protruding ribs 202 are divided into four segments, and the four segments of the second protruding ribs 202 are symmetrically arranged on the outer surface of the second wall 201. The second protruding ribs 202 extend sequentially from the third region 2011A to the seventh region 2015A, and the second protruding ribs 202 are also arranged in a stepped shape. The height of the second protruding ribs 202 decreases with each segment. For example, in the third region 2011A, the height of the second protruding ribs 202 is 3mm, and in the seventh region 2015A, the height is 1mm, to ensure that the first pipe fitting 10 can be completely nested in the second pipe fitting 20, thereby achieving the nesting and locking of the first pipe fitting 10 and the second pipe fitting 20.

[0049] The first component 40 can be a wrench or a connector. When the first component 40 is a wrench, it is used to securely engage with a first-diameter nozzle to rotate and lift it. When the first component 40 is a connector, it can be connected to the second component 50 to securely engage with a second, third, or fourth-diameter nozzle to rotate and lift it. It is understood that the first, second, third, and fourth-diameter nozzles include major nozzle brands on the market, such as Rainbird, Hunter, Toro, K-Rain, Orbit, and Irritrol. In the first embodiment, the first component 40 is a wrench used to securely engage with the first-diameter nozzle to rotate and lift it.

[0050] The first component 40 includes a third wall surface 401, a first top wall 402, and a protrusion 403. The first top wall 402 is connected to the third wall surface 401. The first top wall 402 is provided with a second mounting hole 4021 and a second limiting hole 4022. The second mounting hole 4021 has the same diameter as the first mounting hole 3011 and is used for the insertion of the second pipe fitting 20. The second limiting hole 4022 is provided on the inner wall of the second mounting hole 4021 and is clearance-fitted with the outer wall of the second pipe fitting 20 to form a secondary positioning constraint to prevent the second pipe fitting 20 from radially shifting after insertion. The protrusion 403 is provided along the peripheral edge of the third wall surface 401 to provide gripping force. Multiple protrusions 403 are continuously distributed along the peripheral edge of the third wall surface 401. The distribution spacing of the multiple protrusions 403 is 5-8mm, and the height of the multiple protrusions 403 is 2-4mm, forming a serrated texture, generating high friction with the nozzle surface, and can still apply force stably in humid and oily environments.

[0051] In use, the user directly sleeves the second pipe fitting 20 onto the outside of the first pipe fitting 10. The sleeve structure eliminates the complex procedures required by traditional flange or threaded connections, reducing installation time. The inner wall surface of the second pipe fitting 20 fits against the outer wall surface of the first pipe fitting 10. The physical connection is completed by the tight fit between the inner and outer walls of the second pipe fitting 20, and the locking is achieved by corresponding protrusions. For example, the first protrusion 102 of the first zone 1011A corresponds to the second protrusion 202 of the third zone 2011A, the first protrusion 102 of the second zone 1012A corresponds to the second protrusion 202 of the fourth zone 2012A, the first protrusion 102 of the second zone 1012A corresponds to the second protrusion 202 of the fifth zone 2013A, and the first protrusion 102 of the second zone 1012A corresponds to the second protrusion 202 of the sixth zone 2014A. There is no need for traditional flange bolts or threaded tightening, eliminating complex calibration steps. The handle 30 is fixed to the open end of the first pipe fitting 10 through the first mounting hole 3011, serving as a fulcrum for rotational force application. The end of the second pipe fitting 20 is externally connected to the first component 40, which engages or adsorbs with the protrusion 403 on the surface of the nozzle to achieve nozzle gripping and fixation. When the user rotates the handle 30, the first pipe fitting 10 acts as a rigid inner core, transmitting torque to the second pipe fitting 20 through the contact surface; the stepped diameter reduction design (multi-segment arc surface) of the second pipe fitting 20 matches the outer contour of the nozzle, evenly distributing stress and avoiding local overload that could cause nozzle deformation or slippage. When the nozzle threads loosen, the user pulls the handle 30 axially, and the second pipe fitting 20 continues to hold the nozzle through the first component 40 at its end, and with the guiding action of the sleeve structure, the nozzle is vertically pulled out of the pipe; the stepped second protrusion 202 is designed to scrape rust or deposits on the nozzle surface during the lifting process, assisting in cleaning the threads.

[0052] It should be noted that the first fitting 10, the second fitting 20, the handle 30, and the first component 40 are made of plastic material, which is different from alloy material, and can reduce the total weight of the manual operating tool.

[0053] Please see Figure 6 , Figure 6 This is a three-dimensional structural diagram of the second embodiment of the manual operating tool provided by this utility model;

[0054] Unlike the first embodiment, the second embodiment adds a first guide wire 60 and a second guide wire 70 to the first embodiment. The handle 30 includes a grip portion 302 and a mounting portion 301, which are integrally formed. The grip portion 302 has a through hole 3021 on its side, which communicates with the first limiting hole 3012. The through hole 3021 allows the insertion of a retractable second guide wire 70 from the side of the handle 30. The second guide wire 70 can extend and retract to position the sprinkler assembly buried underground. Similarly, the mounting portion also allows the insertion of a retractable first guide wire 60 from the front of the handle 30.

[0055] Please refer to the following: Figures 7 to 10 , Figure 7 This is a three-dimensional structural diagram of the third embodiment of the manual operating tool provided by this utility model from a first angle. Figure 8 This is a three-dimensional structural diagram of the third embodiment of the manual operating tool provided by this utility model from a second angle; Figure 9 This is a first-angle exploded perspective view of the third embodiment of the manual operating tool provided by this utility model; Figure 10 This is a second-angle exploded perspective view of the third embodiment of the manual operating tool provided by this utility model.

[0056] In the third embodiment, the present invention provides a manual operating tool for removing and replacing nozzles of an underground water supply system. The manual operating tool includes a first fitting 10, a second fitting 20, a handle 30, a first component 40, and a second component 50, all of which are integrally constructed.

[0057] In the third embodiment, the first tube 10 and the second tube 20 are rectangular parallelepipeds, unlike the conical structure of the first embodiment. One end of the first tube 10 can be directly connected to the first component 40, and the other end of the first tube 10 is nested within the second tube 20, which is connected to the handle 30. The first component 40 is externally connected to the second component 50, which is firmly attached to the nozzle to rotate and lift the nozzle.

[0058] In the third embodiment, the handle 30, the first tube 10, the second tube 20, the first component 40, and the second component 50 are detachably connected, which facilitates assembly and carrying.

[0059] The first pipe fitting 10 includes a first wall surface 101 and a plurality of first protruding ribs 102. The first wall surface 101 forms a cylindrical structure with openings at both ends. The first protruding ribs 102 are arranged in a stepped shape, and four segments of the first protruding ribs 102 are symmetrically arranged along the outer surface of the first wall surface 101. Unlike the first embodiment, one end of the first pipe fitting 10 can be nested into the second pipe fitting 20, and the other end of the first pipe fitting 10 is externally connected to the first component 40.

[0060] The second pipe fitting 20 includes a second wall surface 201 and a plurality of second protruding ribs 202. The second wall surface 201 forms a cylindrical structure with openings at both ends. The cylindrical structure is a cuboid structure, unlike the conical structure of the first embodiment. The second protruding ribs 202 are arranged in a stepped manner, with four segments of the second protruding ribs 202 symmetrically arranged along the outer surface of the second wall surface 201. Unlike the first embodiment, one end of the second pipe fitting 20 can be nested in the first mounting hole 3011 of the handle 30, and the other end of the second pipe fitting 20 is sleeved on the first wall surface 101 of the first pipe fitting 10, without contacting the first component 40.

[0061] The handle 30 includes a mounting portion 301 and a gripping portion 302. The mounting portion 301 has a first mounting hole 3011 and a first limiting hole 3012. The first limiting hole 3012 is located around the first mounting hole 3011. The first mounting hole 3011 corresponds to the opening of the second pipe fitting 20. The shape of the first mounting hole 3011 and the opening is rhomboid, which differs from the circular shape of the first embodiment. The first limiting hole 3012 corresponds to the second protruding ridge 202.

[0062] The first component 40 includes a third wall surface 401, a first top wall 402, and a protrusion 403. The first top wall 402 is connected to the third wall surface 401. The first top wall 402 is provided with a second mounting hole 4021 and a second limiting hole 4022. The second limiting hole 4022 is located on the inner wall of the second mounting hole 4021. The protrusion 403 is provided along the peripheral edge of the third wall surface 401. The second mounting hole 4021 is rhomboid in shape, which differs from the circular shape of the first embodiment.

[0063] The second component 50 includes a fourth wall surface 501 and a second top wall 502. The second top wall 502 is connected to the fourth wall surface 501. The outer surface of the second top wall 502 corresponds to the inner surface of the first top wall 402. The second top wall 502 is provided with a third mounting hole 5021 and a third limiting hole 5022. The third limiting hole 5022 is located on the inner wall of the third mounting hole 5021. The first component 40 is fixed to the second component 50 through the third mounting hole 5021. The fourth wall surface 501 includes multiple notches 501A, which are arranged along the periphery of the fourth wall surface 501 to form a groove for digging soil. Furthermore, the end of the fourth wall surface 501 is provided with serrated teeth 506 for cutting grass, allowing the user to quickly unscrew the manual operating tool 100 from the lawn.

[0064] The second component 50 further includes a first strip tooth 503, a second strip tooth 504, and a third strip tooth 505. The first strip tooth 503, the second strip tooth 504, and the third strip tooth 505 are arranged in a stepped manner, and the thickness of the first strip tooth 503, the second strip tooth 504, and the third strip tooth 505 decreases sequentially. One end of the first strip tooth 503 is connected to the inner surface of the second top wall 502, and the other end of the first strip tooth 503 is connected to the inner surface of the fourth wall 501. One end of the second strip tooth 504 is connected to the first strip tooth 503, and the other end of the second strip tooth 504 is connected to the inner surface of the second top wall 502. One end of the third strip tooth 505 is connected to the second strip tooth 504, and the other end of the third strip tooth 505 is connected to the inner surface of the second top wall 502. It is understood that the first strip tooth 503, the second strip tooth 504, and the third strip tooth 505 constitute a rigid component of a three-stage dismantling nozzle. Multiple such hardware components are distributed circumferentially along the inner surface of the second top wall 502, suitable for nozzles of different diameters. For example, the first strip tooth 503, being the thickest, is suitable for larger diameter nozzles; the second strip tooth 504, being thinner than the first strip tooth 503, is suitable for medium diameter nozzles; and the third strip tooth 505, being the thinnest, is suitable for the smallest diameter nozzles. Within a single second component 50, a layered dismantling effect can be effectively achieved, significantly improving work speed.

[0065] It should be noted that the gap between two adjacent rigid parts is just enough for the protrusion 403 to be inserted, so as to better achieve a tight connection between the first component 40 and the second component 50.

[0066] In the third embodiment, when in use, the first component 40 is a connector, and the second component 50 is a wrench. The user can flip the smaller first component 40 and insert it into the base of the larger second component 50. The first component 40 is sequentially connected to the first tube 10, the second tube 20, and the handle 30. The second component 50 can be adapted to nozzles of different diameters and can be unscrewed. The second component 50 also provides an additional length range for the manual operating tool 100.

[0067] Please refer to the following: Figures 11 to 12 , Figure 11 This is a three-dimensional structural diagram of the fourth embodiment of the manual operating tool provided by this utility model. Figure 12 This is an exploded perspective view of the fourth embodiment of the manual operating tool provided by this utility model.

[0068] In the fourth embodiment, the manual operating tool 100 includes a first pipe fitting 10, a second pipe fitting 20, a handle 30, a first component 40, and a second component 50. The handle 30, the first pipe fitting 10, the second pipe fitting 20, the first component 40, and the second component 50 are detachably connected, which facilitates assembly and carrying.

[0069] Unlike the third embodiment, the second component 50 does not have a notch, and the end of the fourth wall surface 501 of the second component 50 has a number of serrations 506.
