[0029] Embodiment 1

[0030] Referring to Figure 1 - Figure 2 , a new type of functional agricultural film, including a main body 1, the main body 1 is composed of a base film 2, a reflective film 3, a thermal insulation layer 4 and a heat insulation layer 5. The material of the base film 2 is polyethylene, and the reflective film 3 is fixed on the outside of the base film 2. The material of the reflective film 3 is polyolefin, so that the light that is about to irradiate through the base film 2 can be reflected by the reflective film 3. The thermal insulation layer 4 is fixed on the outside of the reflective film 3. The material of the thermal insulation layer 4 is polyvinyl chloride, so as to increase the thermal insulation effect when the main body 1 is used through the thermal insulation layer 4. The heat insulation layer 5 is fixed on the outside of the thermal insulation layer 4. The heat insulation layer 5 is a coating made in the background technology with the publication number of "CN106987205A".

[0031] In other embodiments, a light conversion film 6 is fixed on the outside of the heat insulation layer 5, so that the sunlight can be converted into plant-absorbing light through the light conversion film 6.

[0032] The usage process of a new type of positioning structure for functional agricultural films provided by the utility model is as follows: during use, the heat insulation effect of the main body 1 is enhanced by the heat insulation layer 5, and at the same time, the heat preservation effect of the main body 1 during use is increased by the heat preservation layer 4 made of polyvinyl chloride. The light passing through the heat preservation layer 4 is refracted by the reflective film 3 made of polyolefin, thereby further enhancing the heat insulation effect, and the overall body 1 is stabilized by the base film 2.

[0033] Embodiment 2

[0034] Refer to Figure 3 - Figure 8 , for a new type of positioning structure for functional agricultural films, positioning mechanisms for connection are provided at both ends of the main body 1. The positioning mechanism includes a first clamping plate 7, a second clamping plate 8, a fixing nut 9, a connecting rod 10, a threaded section 11, a sliding sleeve 12, an anti-rotation block 13, and a pressing plate 16. The second clamping plate 8 is provided at the bottom of the first clamping plate 7. Pressing plates 16 are slidably connected to both the bottom of the first clamping plate 7 and the top of the second clamping plate 8, so that the main body 1 is clamped by the approach of the two pressing plates 16. Positioning sleeves 15 are fixed to both the bottom of the first clamping plate 7 and the top of the second clamping plate 8, and the pressing plates 16 are slidably connected to the positioning sleeves 15. The fixing nut 9 is slidably connected to the inside of the bottom end of the second clamping plate 8, so that the fixing nut 9 can only be installed and detached by lifting and lowering inside the second clamping plate 8 and cannot be rotated;

[0035] The connecting rod 10 is slidably connected to the inside of the top end of the first clamping plate 7. A threaded section 11 is provided on the outer side of the bottom end of the connecting rod 10, and the threaded section 11 is threadedly connected to the fixing nut 9. When the connecting rod 10 is located inside the first clamping plate 7 and enters the inside of the second clamping plate 8 to be connected to the fixing nut 9, the distance between the first clamping plate 7 and the second clamping plate 8 is stabilized. The sliding sleeve 12 is slidably connected to the outer side of the top end of the connecting rod 10, so that the sliding sleeve 12 can be lifted and lowered on the outer side of the top of the connecting rod 10, but the connecting rod 10 and the sliding sleeve 12 cannot be separated. At the same time, the rotation of the sliding sleeve 12 drives the connecting rod 10 to rotate synchronously. The anti-rotation block 13 is fixed to the top of the sliding sleeve 12. The shape of the anti-rotation block 13 is polygonal. The anti-rotation block 13 is slidably connected to the first clamping plate 7. A rotation groove 14 is provided inside the top end of the anti-rotation block 13, so that an external tool can enter the inside of the rotation groove 14 to drive the anti-rotation block 13 to rotate;

[0036] A rotation cavity 20 is formed inside the first clamping plate 7. The rotation cavity 20 is slidably connected to the connecting rod 10, enabling the connecting rod 10 to rotate and slide inside the rotation cavity 20. Inside the first clamping plate 7 and at the top of the rotation cavity 20, a second lifting cavity 19 is formed. The sliding sleeve 12 is slidably connected to the second lifting cavity 19, allowing the sliding sleeve 12 to descend outside the connecting rod 10 and enter the second lifting cavity 19. Inside the first clamping plate 7 and at the top of the second lifting cavity 19, a first lifting cavity 17 is formed. Inside the first clamping plate 7 and at the top of the first lifting cavity 17, a rotation prevention cavity 18 is formed. The rotation prevention cavity 18, the first lifting cavity 17, the second lifting cavity 19, and the rotation cavity 20 are interconnected. The rotation prevention block 13 is slidably connected to the first clamping plate 7 through the rotation prevention block 13, such that when the rotation prevention block 13 is inside the rotation prevention cavity 18, it cannot rotate, and when the rotation prevention block 13 descends into the first lifting cavity 17, it can rotate;

[0037] At the top end inside the first lifting cavity 17, a limiting plate 21 is slidably connected, such that when the rotation prevention block 13 descends from inside the rotation prevention cavity 18 into the first lifting cavity 17, it drives the limiting plate 21 to descend. At the bottom of the limiting plate 21 and outside the second lifting cavity 19, compression springs 22 are uniformly fixed, such that the descent of the limiting plate 21 drives the compression of the compression springs 22, and after the external force disappears, the rebound of the compression springs 22 drives the limiting plate 21 to reset;

[0038] Extension mechanisms are installed on both sides of the pressing plate 16. The extension mechanisms include extension plates 23, connecting plates 24, first arc-shaped positioning blocks 25, and second arc-shaped positioning blocks 27. Inside both sides of the pressing plate 16, connection grooves 26 are formed. The connecting plates 24 are slidably connected inside the connection grooves 26. One side of the connecting plate 24 is fixed with an extension plate 23, enabling the extension plate 23 to be assembled with the pressing plate 16 through the sliding connection between the connecting plate 24 and the connection groove 26. Inside the extension plate 23 away from the pressing plate 16, a mounting groove is formed. At the top and bottom inside the mounting groove, second arc-shaped positioning blocks 27 are fixed. At the top and bottom of the connecting plate 24, first arc-shaped positioning blocks 25 are fixed. The first arc-shaped positioning blocks 25 and the second arc-shaped positioning blocks 27 are alternately fixed. Thus, when the connecting plate 24 is inside the connection groove 26, positioning is achieved through the alternation of the first arc-shaped positioning blocks 25 and the corresponding second arc-shaped positioning blocks 27, thereby preventing the extension plate 23 from detaching after being assembled with the pressing plate 16, and when multiple extension plates 23 are assembled, the connecting plate 24 on the latter extension plate 23 can enter the mounting groove on the previous extension plate 23.

[0039] The usage process of a new type of positioning structure for functional agricultural thin films provided by the present utility model is as follows: When it is necessary to fix both ends of the main body 1 to limit the position of the main body 1, first, install the two pressing plates 16 at the bottom of the first lifting cavity 17 and the top of the anti-rotation cavity 18 respectively. Then, symmetrically place the first clamping plate 7 and the second clamping plate 8 on the top and bottom of the main body 1 to be clamped. Then, extend the connecting rod 10 out of the inside of the first clamping plate 7, pass through the main body 1, and enter the inside of the second clamping plate 8. Then, press the anti-rotation block 13 through the rotation groove 14, so that the anti-rotation block 13 drives the sliding sleeve 12 to descend on the outside of the connecting rod 10, and the descent of the anti-rotation block 13 drives the compression spring 22 to compress through the limiting plate 21. Then, drive the rotation of the connecting rod 10 by rotating the anti-rotation block 13 through the rotation groove 14, so that the connecting rod 10 enters the fixed nut 9 with a threaded connection, thereby clamping the main body 1 between the two pressing plates 16. After the installation is completed, release the extrusion of the anti-rotation block 13, and let the anti-rotation block 13 reset into the inside of the anti-rotation cavity 18. When the pressing plate 16 needs to be lengthened, install the extension plate 23 through the sliding connection between the first arc-shaped positioning block 25 and the connection groove 26, and fix the position of the extension plate 23 through the staggered cooperation between the connecting plate 24 on the first arc-shaped positioning block 25 and the second arc-shaped positioning block 27 on the connection groove 26.
