[0002] Drip irrigation tapes are widely used in drip irrigation systems. The drip irrigation tapes directly deliver water to the roots of crops, which can not only irrigate precisely but also save water resources. During the use of drip irrigation tapes, they need to be docked with a water supply device, and the docking process is complex, affecting the work efficiency of staff. In order to achieve quick docking, a snap-type drip irrigation tape for agricultural irrigation with the application number 2019223948596 is convenient for disassembling and installing the drip irrigation tape during use, and has high stability, is easy to use, and has high reliability. After the drip irrigation operation is completed, the drip irrigation tape also needs to be quickly removed. However, the existing drip irrigation tape does not have a structure for assisting disassembly, and thus it is not easy to achieve quick disassembly. Summary of the Invention

[0003] The purpose of the present invention is to provide a quick-connect locking type quick connection structure for drip irrigation tapes to solve the problem that the existing drip irrigation tapes do not have a structure for assisting disassembly and thus cannot be quickly disassembled after use.

[0004] To achieve the above purpose, the present invention provides the following technical solution: A quick-connect locking type quick connection structure for drip irrigation tapes, including a drip irrigation tape body and an external connection plate. The end of the drip irrigation tape body is fixedly connected with a connection plate, and the connection plate and the external connection plate are snap-connected, and the external connection plate is connected to the output end of the water supply device; a working plate is fixedly connected to the surface of the external connection plate; a clamping block is slidably arranged on the surface of the connection plate; a limiting column is fixedly connected to the surface of the connection plate, and a stress plate is slidably arranged on the surface of the limiting column; a sealing ring is adhesively connected to the surface of the connection plate.

[0005] Preferably, the working plate passes through the inside of the connection plate, a card slot is opened on the upper surface of the working plate, and an auxiliary plate is fixedly connected to the surface of the connection plate.

[0006] Preferably, the clamping block is slidably arranged inside the auxiliary plate, the end of the clamping block is fixedly connected with a handle, and a second spring for elastic reset is fixedly connected to the lower surface of the handle, and the other side of the second spring is fixedly connected to the upper surface of the auxiliary plate.

[0007] Preferably, the lower surface of the clamping block is inclined, and the clamping blocks are symmetrically distributed on both sides of the connection plate.

[0008] Preferably, a baffle is fixedly connected to the end of the limit post, a first spring for elastic reset is fixedly connected to the surface of the baffle, and the other side of the first spring is fixedly connected to the surface of the force-bearing plate.

[0009] Preferably, an airbag is adhered to the surface of the force-bearing plate, a vertical plate is fixedly connected to the inner wall of the baffle, and the surface of the vertical plate is attached to the surface of the airbag.

[0010] Preferably, a delivery pipe is fixedly connected to the surface of the airbag, and the end of the delivery pipe is connected to the sealing ring.

[0011] Compared with the prior art, the beneficial effects of the present invention are as follows: The quick-connect locking drip irrigation tape quick-connection structure adopts a new structural design, and the specific content is as follows: (1) For the quick-connect locking drip irrigation tape quick-connection structure, when it is necessary to dock the drip irrigation tape body and the connecting plate with the external plate, align the connecting plate with the working plate, insert the working plate into the inside of the connecting plate. At this time, the clamping block will be pushed by the working plate, and the clamping block drives the handle to rise. At this time, the second spring will be stretched. When the connecting plate and the external plate are in contact, the clamping block and the card slot are in the same horizontal direction. At this time, the clamping block enters the card slot under the action of the second spring and the handle, that is, the connecting plate and the external plate have been docked, and the operation process is fast and convenient.

[0012] Furthermore, the clamping block and the working plate are distributed on both sides of the connecting plate and the external plate, optimizing the stability of the docking and clamping.

[0013] (2) For the quick-connect locking drip irrigation tape quick-connection structure, during the docking process, the working plate will push the force-bearing plate, causing the force-bearing plate to slide on the surface of the limit post. At the same time, the first spring will be compressed. When it is necessary to disassemble the drip irrigation tape body, pull the handle so that the end of the handle moves out of the card slot. At this time, the connecting plate and the external plate are not in a clamped state. Then the first spring will push the force-bearing plate. At this time, the connecting plate and the external plate accelerate away under the action of the force-bearing plate and the first spring, making it more convenient and fast for the staff to disassemble the connecting plate and the external plate.

[0014] Furthermore, during the movement of the force-bearing plate, the limit post enables the force-bearing plate to move only in the horizontal direction, ensuring stability.

[0015] (3) For the quick-connect locking drip irrigation tape quick-connection structure, during the docking process, the force-bearing plate will slide on the surface of the limit post, and the force-bearing plate drives the airbag to move towards the vertical plate. At this time, the force-bearing plate cooperates with the vertical plate to squeeze the airbag. At this time, the airbag supplies air to the sealing ring through the delivery pipe, causing the sealing ring to expand. At this time, the sealing ring can better block the docking position, optimizing the anti-leakage effect. BRIEF DESCRIPTION OF THE DRAWINGS

[0018] The following will clearly and completely describe the technical solutions in the embodiments of the present invention with reference to the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. All other embodiments obtained by those of ordinary skill in the art based on the embodiments of the present invention without creative efforts shall fall within the protection scope of the present invention.

[0019] The present invention provides the following technical solution: A quick-connect and lockable drip irrigation tape quick connection structure.

[0020] Embodiment 1: By providing the card block 11 and the card slot 5, the connecting plate 2 and the external connecting plate 3 can be quickly docked. As Figures 1-4 shown, it includes a drip irrigation tape body 1 and an external connecting plate 3. The end of the drip irrigation tape body 1 is fixedly connected with a connecting plate 2, and the connecting plate 2 and the external connecting plate 3 are snap-connected. Moreover, the external connecting plate 3 is connected to the output end of the water supply device; a working plate 4 is fixedly connected to the surface of the external connecting plate 3; a card block 11 is slidably arranged on the surface of the connecting plate 2; the working plate 4 passes through the inside of the connecting plate 2, and a card slot 5 is opened on the upper surface of the working plate 4. Additionally, an auxiliary plate 10 is fixedly connected to the surface of the connecting plate 2.

[0021] A clamping block 11 is slidably arranged inside the auxiliary plate 10, and a handle 12 is fixedly connected to the end of the clamping block 11. Moreover, a second spring 13 for elastic reset is fixedly connected to the lower surface of the handle 12, and the other side of the second spring 13 is fixedly connected to the upper surface of the auxiliary plate 10. The lower surface of the clamping block 11 is inclined, and the clamping blocks 11 are symmetrically distributed on both sides of the connecting plate 2.

[0022] When it is necessary to dock the drip irrigation tape body 1 and the connecting plate 2 with the external plate 3, align the connecting plate 2 with the working plate 4, and insert the working plate 4 into the inside of the connecting plate 2. At this time, the clamping block 11 will be pushed by the working plate 4, and the clamping block 11 will rise inside the auxiliary plate 10. The clamping block 11 drives the handle 12 to rise. At this time, the second spring 13 will be stretched. When the connecting plate 2 and the external plate 3 are in contact, the clamping block 11 and the clamping groove 5 are in the same horizontal direction. At this time, under the action of the second spring 13 and the handle 12, the clamping block 11 enters the clamping groove 5, that is, the connecting plate 2 and the external plate 3 have been docked, and the operation process is fast and convenient.

[0023] Embodiment 2: Different from Embodiment 1, by providing the force-bearing plate 9 and the first spring 8, it plays a role in assisting disassembly. As Figure 3 shown, a limiting post 6 is fixedly connected to the surface of the connecting plate 2, and a force-bearing plate 9 is slidably arranged on the surface of the limiting post 6; a baffle 7 is fixedly connected to the end of the limiting post 6, and a first spring 8 for elastic reset is fixedly connected to the surface of the baffle 7, and the other side of the first spring 8 is fixedly connected to the surface of the force-bearing plate 9.

[0024] During the docking process, the working plate 4 will push the force-bearing plate 9, so that the force-bearing plate 9 slides on the surface of the limiting post 6 (the baffle 7 limits the moving distance of the force-bearing plate 9 to ensure stability). At the same time, the first spring 8 will be compressed. When it is necessary to disassemble the drip irrigation tape body 1, pull the handle 12 so that the end of the handle 12 moves out of the clamping groove 5. At this time, the connecting plate 2 and the external plate 3 are not in a clamped state. Furthermore, the first spring 8 will push the force-bearing plate 9. At this time, the connecting plate 2 and the external plate 3 will accelerate away under the action of the force-bearing plate 9 and the first spring 8, making it more convenient for the staff to disassemble the connecting plate 2 and the external plate 3 and improving work efficiency.

[0025] Embodiment 3: Different from Embodiment 2, by providing the sealing ring 17 and the airbag 15, the docking position of the connecting plate 2 and the external plate 3 has better sealing performance, as Figure 5 and Figure 6 shown, a sealing ring 17 is adhesively connected to the surface of the connecting plate 2, an airbag 15 is adhesively connected to the surface of the force-bearing plate 9, a vertical plate 14 is fixedly connected to the inner wall of the baffle 7, and the surface of the vertical plate 14 is in contact with the surface of the airbag 15. A delivery pipe 16 is fixedly connected to the surface of the airbag 15, and the end of the delivery pipe 16 is connected to the sealing ring 17.

[0026] During the docking process, the force-bearing plate 9 slides on the surface of the limit post 6. The force-bearing plate 9 drives the airbag 15 to move towards the vertical plate 14. At this time, the force-bearing plate 9 cooperates with the vertical plate 14 to squeeze the airbag 15. At this time, the airbag 15 supplies air to the sealing ring 17 through the conveying pipe 16, causing the sealing ring 17 to expand. At this time, the sealing ring 17 can better block the docking position of the connecting plate 2 and the external connecting plate 3, optimizing the anti-leakage effect. After the connecting plate 2 and the external connecting plate 3 are disassembled, the airbag 15 loses the extrusion force. At this time, the air flows back, keeping the internal air pressure of the airbag 15 and the internal air pressure of the sealing ring 17 balanced. At this time, the sealing ring 17 shrinks, facilitating the next docking work of the connecting plate 2 and the external connecting plate 3.

[0027] The above is the working process of the entire device, and the content not described in detail in this specification belongs to the prior art well-known to those skilled in the art.

[0028] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions, and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
