Description

Technical Field

[0001] This utility model relates to the field of sprinkler irrigation bracket technology, and in particular to an adjustable-angle sprinkler irrigation bracket. Background Technology

[0002] Sprinkler supports are key supporting components in sprinkler irrigation systems. They are mainly used to fix sprinkler heads, pipes, and other components, ensuring the stable operation of the sprinkler equipment and achieving uniform irrigation. To optimize irrigation coverage and efficiency during use, sprinkler supports typically need to have an adjustable angle function. By adjusting the angle of the sprinkler support, the elevation angle of the sprinkler head can be adjusted, allowing the sprinkler head to adapt to crops at different heights during irrigation.

[0003] In the existing technology, when adjusting the angle of the upright for installing the sprinkler head, the tilt angle of the upright is usually adjusted by adjusting the adjusting bolt, thereby adjusting the elevation angle of the sprinkler head. However, during the use of the sprinkler head, water flows through the upright and into the sprinkler head. The upright is easily vibrated due to the influence of water flow, and the force is applied to the bolt, which will affect the stability after the upright angle is adjusted. Utility Model Content

[0004] Therefore, it is necessary to provide an adjustable-angle sprinkler bracket to address the issue that the uprights are easily vibrated by water flow, and the force is applied to the bolts, which affects the stability after the upright angle is adjusted.

[0005] Includes: a fixed ring, the surface of which is equipped with three legs, and an upright is rotatably connected to the inner wall of the fixed ring; A fixing mechanism includes a ring fixedly connected to the surface of a fixing ring, one end of the upright rotating shaft passing through the ring, a cylinder slidably connected to the surface of the upright rotating shaft, a slider slidably connected to the inner wall of the cylinder, the bottom end of the slider being fixedly connected to the surface of the upright rotating shaft, a spring being fixedly connected between one end of the upright rotating shaft and the inner wall of the cylinder, a circular plate being fixedly connected to one end of the cylinder, a locking rod being fixedly connected to one end of the circular plate, and multiple locking holes being formed on the surface of the ring.

[0006] In one embodiment, the fixing mechanism further includes a U-shaped block, the inner wall of which is fixedly connected to two locking blocks. The upper surface of the circular plate has multiple first circular holes that match the locking blocks, and the upper surface of the ring has second circular holes that match the locking blocks. By having the two locking blocks engage with the second circular holes and one of the first circular holes respectively, it is beneficial to limit the horizontal movement of the circular plate.

[0007] In one embodiment, a round rod is slidably connected to the inner wall of the U-shaped block. The surfaces of the circular plate and the ring are each provided with mounting holes matching the round rod. The U-shaped block, the circular plate, and the ring are fixed together by the round rod, and nuts are threaded onto both ends of the round rod. This facilitates the reinforcement of the connection between the locking blocks and the first and second circular holes, enhancing the stability of the two locking blocks in maintaining the upper limit of the circular plate in the horizontal direction.

[0008] In one embodiment, the middle section of the round rod is smooth, and both ends of the round rod are threaded. The round rod and the nut are fixedly connected by the threads. This facilitates the interaction between the nut and the threads to achieve final locking.

[0009] In one embodiment, the center of the circular plate coincides with the center of the circular ring, and the locking rod and multiple locking holes are arranged on the same annular path. This helps to ensure the stability of the locking rod engaging with the locking holes after rotation.

[0010] In one embodiment, the end of the locking rod away from the circular plate is bent into an arc shape, and the diameter of the locking rod matches the diameter of the locking hole. This facilitates better insertion of the locking rod into the locking hole while ensuring stability when the locking rod engages with the hole.

[0011] In one embodiment, an operating rod is fixedly connected to the end of the circular plate away from the cylinder, and multiple arc-shaped rods distributed in a ring are fixedly connected to the surface of the operating rod. This facilitates the operator in pulling the circular plate to move or rotate it more easily.

[0012] In one embodiment, the center of the locking rod is on the same axis as the center of one of the first circular holes. This helps to ensure that when the locking rod is engaged with one of the locking holes, one of the first circular holes is aligned with the second circular hole. Beneficial effects

[0013] 1. In the above scheme, the interaction between the circular plate, cylinder, and slider facilitates the rotation of the upright, thereby adjusting the tilt angle of the nozzle installed on the upright. After the angle adjustment is completed, the interaction of the spring, locking rod, and locking hole in the fixing mechanism helps to apply a certain force to the locking rod and engage with the locking hole, thus limiting the rotation of the circular plate, cylinder, and upright. By engaging the two locking blocks with the second circular hole and one of the first circular holes respectively, the circular plate and the ring are integrated, limiting the horizontal movement of the circular plate. The fixing mechanism helps to prevent the circular plate from rotating or moving during use, ensuring the stability of the upright after the tilt angle adjustment is completed, thus ensuring the stability of the nozzle during irrigation after the angle adjustment.

[0014] 2. After the two locking blocks are respectively engaged with one of the first and second round holes, the round rod is used to longitudinally penetrate the U-shaped block, the round plate, the ring and the two locking blocks, and is locked and positioned by nuts. This helps to strengthen the engagement of the locking blocks with the first and second round holes and enhances the stability of the two locking blocks in the upper limit of the round plate in the horizontal direction.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this utility model. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0019] The following is combined with Figure 1 - Figure 5 This invention describes an adjustable-angle sprinkler bracket.

[0020] In one embodiment, an adjustable-angle sprinkler bracket includes: a fixing ring 100, three legs 200 mounted on the surface of the fixing ring 100, and a vertical rod 300 rotatably connected to the inner wall of the fixing ring 100. The fixing mechanism 400 includes a ring 440 fixedly connected to the surface of the fixing ring 100. One end of the rotating shaft of the upright 300 passes through the ring 440. A cylinder 410 is slidably connected to the surface of the rotating shaft of the upright 300. A slider 411 is slidably connected to the inner wall of the cylinder 410. The bottom end of the slider 411 is fixedly connected to the surface of the rotating shaft of the upright 300. A spring 430 is fixedly connected between one end of the rotating shaft of the upright 300 and the inner wall of the cylinder 410. A circular plate 420 is fixedly connected to one end of the cylinder 410. A locking rod 421 is fixedly connected to one end of the circular plate 420. Multiple locking holes 441 are opened on the surface of the ring 440.

[0021] In this embodiment, one end of the support leg 200 is installed with the fixing ring 100 by bolts, and after the three support legs 200 are installed with the fixing ring 100, the three support legs 200 are arranged in a ring. The inner diameter of the fixing ring 100 is larger than the outer diameter of the upright 300. Therefore, when the upright 300 rotates, the surface of the upright 300 and the inner wall of the fixing ring 100 do not affect each other. The upper and lower ends of the upright 300 are threaded. During use, the device is installed with the external water pipe through the thread at the lower end of the upright 300 and with the nozzle through the thread at the upper end of the upright 300. The middle part of the upright 300 is hollow. Therefore, after the upright 300 is installed with the water pipe and nozzle, and the water source is turned on, the water solution will enter the nozzle through the upright 300 and spray out from the nozzle. Since the water pipe connected to the upright 300 is a flexible hose, it can be ensured that the upright 300 can be properly connected to the external water pipe when the upright 300 is rotated. In the initial state, the upright 300 is perpendicular to the horizontal plane and the spring 430 is in the released state. The locking rod 421 is engaged with one of the locking holes 441, thereby limiting the rotation of the circular plate 420, the cylinder 410 and the upright 300.

[0022] like Figure 3 and Figure 5 As shown, the fixing mechanism 400 also includes a U-shaped block 450. Two locking blocks 451 are fixedly connected to the inner wall of the U-shaped block 450. The upper surface of the circular plate 420 is provided with a plurality of first circular holes 422 that match the locking blocks 451. The upper surface of the circular ring 440 is provided with a second circular hole 442 that matches the locking blocks 451.

[0023] In this embodiment, when the device is in its initial state, the locking rod 421 is engaged with one of the locking holes 441, the center of one of the first circular holes 422 and the center of the second circular hole 442 are on the same axis, one locking block 451 is engaged with one of the first circular holes 422, and the other locking block 451 is engaged with the second circular hole 442. At this time, the two sides of the inner wall of the U-shaped block 450 are respectively in contact with the opposite sides of the circular plate 420 and the circular ring 440. When it is necessary to rotate the circular plate 420, the two locking blocks 451 must first be released from their engagement with the first circular hole 422 and the second circular hole 442.

[0024] like Figure 5 As shown, a round rod 460 is slidably connected to the inner wall of the U-shaped block 450. The surfaces of the round plate 420 and the ring 440 are all provided with mounting holes 470 that match the round rod 460. The U-shaped block 450, the round plate 420 and the ring 440 are fixed by the round rod 460. Nuts 461 are threaded to both ends of the round rod 460.

[0025] In this embodiment, the number of mounting holes 470 on the surface of the circular plate 420 is the same as the number of multiple first circular holes 422. The multiple mounting holes 470 on the surface of the circular plate 420 correspond one-to-one with the multiple first circular holes 422, and the mounting holes 470 are connected to the corresponding first circular holes 422. The number of mounting holes 470 on the surface of the ring 440 is one, and the center of the mounting hole 470 on the surface of the ring 440 is on the same axis as the center of the second circular hole 442. The locking block 451 has a through hole that matches the round rod 460. When the two locking blocks 451 enter one of the first circular holes 422 and the second circular hole 442 respectively, the through hole of the locking block 451, one of the mounting holes 470 on the surface of the circular plate 420 and the mounting hole 470 on the surface of the ring 440 are on the same axis. Therefore, the round rod 460 can pass through one of the mounting holes 470 and the through hole on the surface of the circular plate 420 and the mounting hole 470 on the surface of the ring 440.

[0026] like Figure 5 As shown, the middle part of the round rod 460 is a smooth rod, and both ends of the round rod 460 are provided with threads. The round rod 460 and the nut 461 are fixedly connected by the threads.

[0027] In this embodiment, when the nuts 461 are tightened with the threaded connection, a washer is provided between the opposite ends of the two nuts 461 and the U-shaped block 450. The washer is a rubber component, so that the nuts 461 are not easy to loosen after being tightened.

[0028] like Figure 3 As shown, the center of the circular plate 420 coincides with the center of the circular ring 440, and the locking rod 421 and multiple locking holes 441 are arranged on the same annular path.

[0029] In this embodiment, the rotation path of the locking rod 421 coincides with the distribution path of the multiple locking holes 441. Therefore, it can be ensured that the locking rod 421 can engage with one of the locking holes 441 after rotation.

[0030] like Figure 4 As shown, the end of the locking rod 421 away from the circular plate 420 is bent into an arc shape, and the diameter of the locking rod 421 matches the diameter of the locking hole 441.

[0031] In this embodiment, when the locking rod 421 enters the locking hole 441, the surface of the locking rod 421 is in contact with the inner wall of the locking hole 441.

[0032] like Figure 3 As shown, an operating rod is fixedly connected to the end of the circular plate 420 away from the cylinder 410, and multiple arc-shaped rods distributed in a ring are fixedly connected to the surface of the operating rod.

[0033] In this embodiment, the arc-shaped rod is a rubber component, which makes it easier for the operator to operate the circular plate 420.

[0034] like Figure 4 As shown, the center of the lever 421 and the center of one of the first circular holes 422 are on the same axis.

[0035] In this embodiment, the number of multiple first circular holes 422 is the same as the number of multiple locking holes 441. In the initial state of the device, the multiple first circular holes 422 and the multiple locking holes 441 correspond one-to-one on the vertical plane. When the circular plate 420 drives the locking rod 421 to rotate, when the locking rod 421 engages with any one of the locking holes 441, one of the first circular holes 422 and the second circular hole 442 will be on the same axis.

[0036] Working Principle: When using this device, after installing the nozzle and external water inlet pipe to the upright 300, if it is necessary to adjust the tilt angle between the nozzle and the horizontal plane, release the two locking blocks 451 from the first circular hole 422 and the second circular hole 442. After releasing the locking blocks, pull the operating rod to move the circular plate 420, the cylinder 410, and the locking rod 421 away from the circular ring 440, causing the locking rod 421 to release from the locking hole 441. The spring 430 then pulls up. At this time, according to the required tilt direction of the nozzle, the operating rod drives the circular plate 420, the locking rod 421, and the cylinder 410 to rotate synchronously. Under the action of the slider 411, this drives the rotating shaft of the upright 300 to rotate synchronously. The upright rod 300 drives the nozzle to rotate, changing the nozzle's tilt angle. When the nozzle rotates to the required angle, the locking rod 421 is aligned with an adjacent locking hole 441, and the pulling force on the operating rod is released. At this time, under the action of the spring 430, the locking rod 421 enters the locking hole 441 to lock, limiting the rotation of the circular plate 420, the cylinder 410, and the upright rod 300. Then, the two locking blocks 451 enter one of the first circular holes 422 and the other of the second circular hole 442, thereby limiting the horizontal movement of the circular plate 420. The circular rod 460 passes through the U-shaped block 450, the mounting hole 470, and the through hole in sequence, and is finally locked and fixed using the nut 461.

Although this utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art should understand that modifications can still be made to the technical solutions described in the foregoing embodiments, or equivalent substitutions can be made to some of the technical features.
