The defect is that the main joint surfaces generally need to be fastened with bolts, screws, etc., which is inconvenient to assemble and disassemble, and needs to be improved. Utility Model Content

[0003] In order to solve at least one of the above technical defects, the utility model provides the following technical solutions:

[0004] The present application document discloses a farmland water conservancy water supply channel, comprising a semicircular trough-shaped main body formed of plastic material, limiting plates formed at both end surfaces of the notch of the main body, a slot is arranged at the head end of the main body along its depth direction and a matching plug ring is arranged at the tail end, a clamping plate 1 is arranged on both sides of the plug ring, a clamping plate 2 is arranged on both sides of the slot, a convex column is arranged on the plate surface of the clamping plate 2 and a locking rod is elastically hinged on the convex column, the top end of the convex column is threadedly connected to the top cover and the side of the top cover abuts the locking rod, the top cover is screwed down to reduce the angle between the locking rod and the convex column, a locking hole is arranged on the clamping plate 1, when the two main bodies are docked, the plug ring is in the slot and the clamping plate 1 is fitted with the clamping plate 2, the convex column and the locking rod extend from the locking hole and the clamping plate 1 is limited by the locking rod.

[0005] The improved structure in this scheme is to form a water supply channel by splicing a main body of plastic material. When the main body is docked, the plug-in structure of the slot and the plug ring is locked in the axial direction. The first and second clamping plates cooperate with the protruding columns and the locking rod to lock in the depth direction of the main body.

[0020] The utility model is further described below in conjunction with the accompanying drawings and specific embodiments.

[0021] Example 1

[0022] like Figure 1 , Figure 2 , Figure 3 As shown, in this example, the farmland water supply channel includes a semicircular trough-shaped main body 1 formed of plastic material. The main body 1 is formed of polycarbonate material, and multiple main bodies 1 are connected end to end to form a channel for water delivery.

[0023] Limiting plates 2 are horizontally extended from both end faces of the notch of the main body 1. For example, when a canal is dug in a field and the main body is then assembled in the canal, the limiting plates abut against the end faces of the notch of the canal to form a limit. Through holes can be formed on the limiting plates to facilitate fixing to the end faces of the notch of the canal by bolts, columns, etc.

[0024] In this example, the groove wall at the head end of the main body 1 is concavely formed into a slot 4 along its depth direction, and a convex ring, i.e., an insert ring 3, is convexly formed on the bottom surface at the tail end of the main body 1. When the two main bodies are spliced, the insert ring at the top corresponds to the slot and then moves down, so that the insert ring 3 is in the slot 4. Figure 2 shown.

[0025] In this example, a card plate 5 is formed on both sides of the insert ring 3, and the flat card plate 5 is placed horizontally. A flat card plate 2 9 is formed on both sides of the slot 4, and the card plate 2 9 is placed horizontally. Card plate 1 5, card plate 2 9 and the limiting plate 2 are integrally formed. The thickness of card plate 1 5 and card plate 2 9 is less than the thickness of the limiting plate 2, and the sum of the thickness of card plate 1 5 and card plate 2 9 is the same as the thickness of the limiting plate 2. There is a groove between the bottom surface of card plate 1 and the limiting plate for the placement of card plate 2, and there is a groove between the top surface of card plate 2 and the limiting plate for the placement of card plate 1. After splicing, it helps to improve the aesthetics.

[0026] In this example, a boss 10 is installed on the top surface of the second card plate 9 , such as the bottom of the boss 10 is embedded in a hole formed on the top surface of the second card plate 9 . The locking rod 14 is elastically hinged at the peripheral wall of the protruding column 10. For example, the locking rod 14 is installed at a relative position on the peripheral wall of the protruding column 10, and the end of the rod-shaped locking rod 14 is hinged at the peripheral wall of the protruding column 10 through a pivot or the like. An elastic member 13 is installed between the locking rod 14 and the peripheral wall of the protruding column 10 in the rotation direction of the locking rod 14 to form an elastic hinge. The elastic member, such as a spring, causes the locking rod 14 to expand outward under the action of the spring, and a through hole, namely a locking hole 15, is formed at a corresponding position on the card plate 5. In the expanded state, the distance between the tail ends of the locking rod 14 is greater than the diameter of the locking hole 15. When the main body is spliced, the card plate 1 5 fits with the card plate 2 9, and the protruding column 10 extends from the locking hole 15. The locking rod retracts after being squeezed, and then expands outward under the action of the spring. After expanding outward, the locking rod forms a limit on the card plate 1 to limit the separation of the card plate 1 and the card plate 2 in the depth direction of the main body.

[0027] In this example, the top cover 6 is threadedly connected at the top end of the protruding column 10, and the side of the top cover 6 abuts against the locking rod 14. The top cover can be twisted up and down to change the angle between the locking rod and the protruding column.

[0028] Specifically, the top cover 6 includes a cover body and a stud 7. The stud 7 is formed at the bottom wall of the cover body cavity and extends axially along the cover body. A threaded hole 11 is formed axially at the top end surface of the boss 10. The stud 7 is threadedly engaged in the threaded hole 11. The top cover can be screwed to move up and down relative to the boss. When moving down, the locking rod is pressed down by the side of the cover body until the locking rod is disengaged from the limit of the card plate 1, and the card plate 1 and the card plate 2 can be separated.

[0029] In addition, a plug post 7 can be installed at the bottom wall of the main body 1. The bottom end of the plug post 7 is needle-shaped to facilitate insertion into the field. For the installation of the plug post, it can be integrally formed, or a screw barrel 8, that is, an internally threaded barrel, can be integrally formed at the bottom wall of the main body 1. The end of the plug post 7 is threadedly connected to the screw barrel 8 to facilitate the installation of the plug post.

[0030] The above are only preferred implementations of the utility model. The protection scope of the utility model is not limited to the above embodiments. All technical solutions under the idea of ​​the utility model belong to the protection scope of the utility model. It should be pointed out that for ordinary technicians in this technical field, some improvements and modifications without departing from the principle of the utility model should also be regarded as the protection scope of the utility model.
