Description

Technical Field

[0001] This utility model relates to the field of water-saving irrigation technology, and in particular to an anti-loosening drip irrigation tape core plug. Background Technology

[0002] Drip irrigation tape cores are widely used in water-saving irrigation technology. Traditional drip irrigation tape core plugs mostly adopt an integrated structure or a simple plug-and-play connection, with the plug and core usually having an interference fit or a threaded connection. After prolonged use, interference fit plugs are prone to loosening and falling off due to repeated stress during the drip irrigation tape winding process, affecting the service life of the drip irrigation tape; while threaded plugs provide a more secure connection, the installation and disassembly process is cumbersome. In addition, traditional plugs lack an effective internal support structure, making the core prone to deformation and affecting the smoothness of the drip irrigation tape winding.

[0003] Based on this, this utility model designs an anti-loosening drip tube core plug to solve the above problems. Utility Model Content

[0004] The purpose of this invention is to provide an anti-loosening drip tube core plug to solve the problems in the prior art.

[0005] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0006] A type of anti-loosening drip tube core plug includes a cylindrical core and plugs installed at both ends of the core. Rectangular limiting holes are opened on the outer circumferential surfaces of the upper and lower ends of the core, and the plugs are detachably installed on the core. The outer edge of the plug is horizontally fixed with a limiting edge, and the inner edge is connected to a tapered opening. A connecting ring is fixed on the inner wall of the connection between the plug and the tapered opening, and a high-strength bracket is fixed inside the connecting ring. A rectangular mounting hole is opened on the outer circumferential surface of the plug. A connecting plate is fixed upward at the center of the bottom end of the rectangular mounting hole. The length and width of the connecting plate are smaller than the rectangular mounting hole. The top of the rectangular mounting hole extends horizontally to the limiting edge, and the free end of the connecting plate is fixed with a limiting block facing outward.

[0007] The high-strength support includes a circular tube support pipe vertically fixed to an annular support plate and a second support plate vertically fixed to a radial support plate. The circular tube support pipe is coaxial with the annular support plate, the radial support plate is connected to a connecting ring, and the second support plate is fixed to the inner wall of the plug.

[0008] The volume of the connecting plate is smaller than that of the rectangular mounting hole.

[0009] The radial support plate is provided with radial support plate reinforcing ribs at both ends where it connects to the connecting ring.

[0010] An arc-shaped reinforcing rib is fixed on the connecting ring, and the other side of the arc-shaped reinforcing rib is fixed to the inner wall of the plug.

[0011] The end cap and the core are fitted with a clearance.

[0012] The diameter of the limiting edge is larger than the diameter of the core.

[0013] This utility model has the following beneficial effects:

[0014] 1. By using the rectangular limiting holes of the core and the limiting blocks on the plug, all the limiting blocks need to be pressed at the same time during disassembly, which achieves both quick positioning and stable connection, and high disassembly and assembly efficiency.

[0015] 2. The plug is equipped with a high-strength support, which provides strong support, reduces core deformation, and extends service life. Attached Figure Description

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. It should be understood that the terms "upper", "middle", "outer", "inner", "lower" etc., which indicate orientation or positional relationship, are only for the convenience of describing the present utility model and simplifying the description, and do not indicate or imply that the components or elements referred to must have a specific orientation, and therefore should not be construed as a limitation of the present utility model.

[0024] The attached figures illustrate specific embodiments of this utility model, such as... Figures 1-4 As shown, this utility model is an anti-loosening drip tube core plug, including a cylindrical core 3 and plugs 1 installed at both ends of the core 3. The core 3 is cylindrical with several hollow holes to reduce its own weight. Rectangular limiting holes 2 are opened on the outer circumference of the upper and lower ends of the core 3. The rectangular limiting holes 2 can completely accommodate the limiting blocks 8. The plugs 1 and the core 3 are fitted with a clearance fit to ensure no shaking after installation. Through the snap-fit ​​structure of the rectangular limiting holes 2 and the limiting blocks 8, combined with the light pre-tightening force of the clearance fit, the problem of loosening due to interference fit is avoided, and it can be quickly disassembled and assembled without threaded tools.

[0025] Rectangular limiting holes 2 are opened on the outer circumferential surfaces of the upper and lower ends of the core 3, and the plug 1 is detachably installed on the core 3; the outer edge of the plug 1 is horizontally fixed with a limiting edge 4, the diameter of the limiting edge 4 is larger than the diameter of the core 3, which can limit the lateral movement of the drip tape and prevent it from deviating during winding.

[0026] The connection end between the plug 1 and the core 3 is the inner end, and its edge is a tapered opening 5 to reduce the resistance when the plug 1 is inserted into the core 3.

[0027] A connecting ring 14 is fixed to the inner wall of the connection with the tapered opening 5, and a high-strength bracket is fixed inside the connecting ring 14. A rectangular mounting hole 6 is opened on the outer circumference of the plug 1. A connecting plate 7 is fixed upward at the center of the bottom of the rectangular mounting hole 6. The length and width of the connecting plate 7 are smaller than the rectangular mounting hole 6 to ensure that the connecting plate can slide up and down in the hole, which can temporarily extend the length of the core 3. The top of the rectangular mounting hole 6 extends horizontally to the limiting edge 4, and the extension is large enough to accommodate the passage of the limiting block 8. The free end of the connecting plate 7 is fixed to the limiting block 8 facing outward. During installation, the rectangular mounting hole 6 on the limiting edge 4 provides a position for the limiting block 8 to move downward, reducing resistance and extending the service life of the limiting block 8.

[0028] The high-strength support includes a circular tube support pipe 13 vertically fixed on an annular support plate 9 and a second support plate 12 vertically fixed on a radial support plate 10. The circular tube support pipe 13 is coaxial with the annular support plate 9, forming a central support column. The radial support plate 10 is connected to a connecting ring 14. The second support plate 12 is fixed to the inner wall of the plug 1, forming a radial support skeleton. Radial support plate reinforcing ribs 11 are provided at both ends of the radial support plate 10 where it is connected to the connecting ring 14 to improve torsional strength.

[0029] An arc-shaped reinforcing rib 15 is fixed on the connecting ring 14, and the other side of the arc-shaped reinforcing rib 15 is fixed to the inner wall of the plug 1 to improve the overall strength.

[0030] The usage method of this embodiment is as follows:

[0031] Install the end caps 1 at both ends of the core 3, ensuring that the limiting blocks 8 are engaged in the rectangular limiting holes 2. Install the core 3 onto the drip irrigation tape winding machine and wind the drip tape at a uniform speed. The high-strength bracket supports the core 3 to prevent it from bending or deforming due to gravity or tension. After winding to the predetermined length, wrap the rolled drip tape with plastic film for easy storage and transportation.

[0032] When laying the drip irrigation tape, insert the limiting edges 4 of the end caps at both ends of the core into the slots of the drip irrigation tape laying machine for precise positioning. Start the laying machine, and the core 3 will rotate accordingly, releasing the drip irrigation tape at a uniform speed. After the drip irrigation tape is released, when disassembling, simultaneously press all the limiting blocks 8 to disengage them from the rectangular limiting holes 2, and remove the end caps 1. Collect the empty core 3 and store the end caps 1 and core 3 separately to prevent material aging.
