Abstract
Description
Technical Field
[0001] This utility model relates to the technical field of drip irrigation pipes, and in particular to a foldable, water-saving drip irrigation pipe. Background Technology
[0002] Drip irrigation uses plastic pipes to deliver water to the roots of crops through orifices or drippers on branch pipes with a diameter of about 10mm. It can directly drip water into the roots of plants without wetting the leaves or causing surface runoff, making it very water-saving.
[0003] Currently, most of the branch pipes used in drip irrigation are PE hoses. Drip nozzles are installed at regular intervals on the PE hoses for drip irrigation. However, existing PE hose branch pipes are prone to folding during installation, which affects the smooth flow of water and may even cause blockages in the pipes, leading to pipe joints bursting and affecting normal drip irrigation. Utility Model Content
[0004] To solve the above-mentioned technical problems, this utility model provides a fold-resistant water-saving drip irrigation pipe that can prevent pipe folding, keep water flow unobstructed, avoid pipe blockage and breakage at the joint, and ensure normal drip irrigation.
[0005] Technical solution
[0006] To achieve the above objectives, this utility model provides the following technical solution: a foldable water-saving drip irrigation pipe, comprising branch pipes and multiple positioning mechanisms equidistantly arranged on the branch pipes. The positioning mechanism includes a U-shaped positioning ring and a U-shaped bracket. The U-shaped bracket is fixedly arranged on the top of the branch pipe, and a pin is inserted into the U-shaped bracket. A pin hole is provided in the middle of the U-shaped positioning ring to cooperate with the pin. The U-shaped positioning ring is engaged with the U-shaped bracket through the cooperation of the pin and the pin hole. Connecting plates are integrally fixed on both sides of the U-shaped positioning ring. Sliding holes are provided on both sets of connecting plates. Positioning cone rods are slidably arranged on both sets of connecting plates through the cooperation of the sliding holes. Pressure plates are fixedly provided at the top of both sets of positioning cone rods. Conical tips are fixedly provided at the bottom of both sets of positioning cone rods. The positioning cone rods, pressure plates, and cone tips are all integral structures.
[0007] Preferably, two sets of limiting blocks are symmetrically fixed on one side of the U-shaped positioning ring, and the inner sides of the two sets of limiting blocks are in contact with the front and rear ends of the U-shaped card seat.
[0008] Preferably, clamping rubber blocks are fixed on the inner walls of both sides of the U-shaped positioning ring, and the two sets of clamping rubber blocks symmetrically abut against both sides of the branch pipe.
[0009] Preferably, pull rings are fixedly provided at the top of both sets of pressure plates.
[0010] Preferably, a sliding sleeve is fixedly provided in the sliding hole of each of the two sets of connecting plates.
[0011] Preferably, the front and rear corners of the top of the U-shaped card holder are rounded.
[0012] Compared with the prior art, the beneficial effects of this utility model are as follows: In use, after connecting the branch pipe inlet to the branch pipe, the branch pipe is laid. A set of U-shaped clamps is installed at regular intervals on the branch pipe. During laying, the branch pipe is straightened section by section according to the intervals of the U-shaped clamps, ensuring the U-shaped clamps are vertically upward. Then, the pin is pulled out, and the U-shaped positioning ring is clamped onto the U-shaped clamp. The bottom inner side of the U-shaped clamp is curved to ensure a tight fit between the inner wall of the U-shaped positioning ring and the U-shaped clamp. Finally, the pin is passed through the pin hole and inserted. The U-shaped positioning ring is positioned on the U-shaped bracket by the cooperation of the pin and the pin hole to prevent the U-shaped positioning ring from detaching from the U-shaped bracket. At this time, the connecting plates on both sides of the U-shaped positioning ring are horizontal. Then, the positioning cone rod is vertically driven into the ground by the pressure plate. The positioning cone rod fixes the U-shaped positioning ring. The cooperation between the U-shaped positioning ring and the pin keeps the branch pipe straight during laying, avoids the branch pipe from being folded, and thus keeps the water flow unobstructed, avoids pipe blockage and joint breakage, and ensures that drip irrigation is carried out normally.

[0020] The specific embodiments of this utility model will be described in further detail below with reference to the accompanying drawings and examples. The following examples are used to illustrate this utility model, but are not intended to limit its scope.
[0021] Example
[0022] Please see Figures 1-6 This utility model discloses a foldable, water-saving drip irrigation pipe, comprising a branch pipe 1 and multiple positioning mechanisms equidistantly arranged on the branch pipe 1. Each positioning mechanism includes a U-shaped positioning ring 2 and a U-shaped mounting base 3. The U-shaped mounting base 3 is fixedly mounted on the top of the branch pipe 1, and a pin 4 is inserted into the U-shaped mounting base 3. A pin hole 5 is provided in the middle of the U-shaped positioning ring 2 to cooperate with the pin 4. The U-shaped positioning ring 2 is secured to the U-shaped mounting base 3 through the cooperation of the pin 4 and the pin hole 5. Connecting plates 6 are integrally fixed on both sides of the U-shaped positioning ring 2. Each of the two sets of connecting plates 6 has a sliding hole, and positioning cone rods 7 are slidably mounted on each of the two sets of connecting plates 6 through the sliding holes. A pressure plate 8 is fixedly mounted at the top of each of the two sets of positioning cone rods 7, and a cone tip 9 is fixedly mounted at the bottom of each of the two sets of positioning cone rods 7. The positioning cone rods 7, pressure plates 8, and cone tips 9 are all integral structures. In use, after connecting the inlet of the branch pipe 1 to the branch pipe, the branch pipe 1 is laid. Positioning mechanisms are arranged at regular intervals on the branch pipe 1. A set of U-shaped brackets 3 is installed. During installation, the branch pipe 1 is straightened section by section according to the intervals of the U-shaped brackets 3, so that the U-shaped brackets 3 are vertically upward. Then, the pin 4 is pulled out, and the U-shaped positioning ring 2 is clamped onto the U-shaped bracket 3. The bottom inner side of the U-shaped bracket 3 is curved to ensure a tight fit between the inner wall of the U-shaped positioning ring 2 and the U-shaped bracket 3. Then, the pin 4 is passed through the pin hole 5 and inserted into the U-shaped bracket 3. The U-shaped positioning ring 2 is positioned by the cooperation of the pin 4 and the pin hole 5. To prevent the U-shaped positioning ring 2 from detaching from the U-shaped bracket 3, the connecting plates 6 on both sides of the U-shaped positioning ring 2 are horizontal. Then, the positioning cone rod 7 is vertically driven into the ground by the pressure plate 8. The positioning cone rod 7 fixes the U-shaped positioning ring 2 in place. Then, through the cooperation of the U-shaped positioning ring 2 and the pin 4, the branch pipe 1 is kept straight during installation, avoiding folding of the branch pipe 1. This ensures that the water flow is smooth and prevents pipe blockage that could cause the joint to break, thus ensuring that drip irrigation is carried out normally.
[0023] Two sets of limiting blocks 10 are symmetrically fixed on one side of the U-shaped positioning ring 2. The inner sides of the two sets of limiting blocks 10 are in contact with the front and rear ends of the U-shaped card seat 3. By setting the limiting blocks 10, when installing the U-shaped positioning ring 2, the pin hole 5 on the U-shaped positioning ring 2 can be quickly aligned with the pin 4 by the limiting of the limiting blocks 10, thereby improving the installation efficiency of the U-shaped positioning ring 2.
[0024] Clamping blocks 11 are fixedly provided on the inner walls of both sides of the U-shaped positioning ring 2. The two sets of clamping blocks 11 are symmetrically abutted against both sides of the branch pipe 1. By setting the clamping blocks 11, the clamping blocks 11 abut against the outer wall of the branch pipe 1, thereby clamping the branch pipe 1 to ensure the stability of the branch pipe 1.
[0025] Both sets of pressure plates 8 are fixedly provided with pull rings 12 at their top ends; by providing pull rings 12, it is convenient to pull the positioning cone rod 7 out of the ground after use, which brings convenience to use.
[0026] Sliding sleeves 13 are fixedly installed in the sliding holes on both sets of connecting plates 6; by setting the sliding sleeves 13, the positioning cone rod 7 can slide more smoothly.
[0027] The top front and rear corners of the U-shaped card holder 3 are all provided with rounded corners 14; by setting the rounded corners 14, the corners on both sides of the top of the U-shaped card holder 3 can be made smoother, avoiding scratching the hands when installing the U-shaped positioning ring 2.
[0028] This utility model discloses a foldable, water-saving drip irrigation pipe. Its working principle is as follows: After connecting the inlet of branch pipe 1 to the branch pipe, branch pipe 1 is laid. U-shaped retainers 3 are installed at regular intervals on branch pipe 1. During laying, branch pipe 1 is straightened segment by segment according to the intervals of the U-shaped retainers 3, ensuring the U-shaped retainers 3 are vertically upward. Then, the pin 4 is pulled out, and the U-shaped positioning ring 2 is inserted into the U-shaped retainer 3. The pin 4 is then passed through the pin hole 5 and inserted into the U-shaped retainer 3. The U-shaped positioning ring 2 is positioned by the cooperation of the pin 4 and the pin hole 5. To prevent the U-shaped positioning ring 2 from detaching from the U-shaped bracket 3, the connecting plates 6 on both sides of the U-shaped positioning ring 2 are horizontal. Then, the positioning cone rod 7 is vertically driven into the ground by the pressure plate 8, and the U-shaped positioning ring 2 is fixed by the positioning cone rod 7. Then, through the cooperation of the U-shaped positioning ring 2 and the pin 4, the branch pipe 1 is kept straight during laying, and the branch pipe 1 is prevented from folding. After use, the positioning cone rod 7 is pulled out from the ground by the pull ring 12, and then the pin 4 is pulled out and the U-shaped positioning ring 2 is removed. The U-shaped positioning ring 2 and the pin 4 are stored away for future use.
[0029] The present invention relates to a water-saving drip irrigation pipe that is foldable. Its installation, connection or setting methods are all common mechanical methods, and any method that can achieve its beneficial effect can be implemented.
[0030] The above description is only a preferred embodiment of the present utility model. It should be noted that for those skilled in the art, several improvements and modifications can be made without departing from the technical principles of the present utility model, and these improvements and modifications should also be considered within the protection scope of the present utility model.
