Detailed Implementation

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0023] Example 1

[0024] Please see Figure 1-5 The present invention provides the following technical solution: a film fixing device in an agricultural greenhouse, comprising an installation block assembly 1, film pressing rod assemblies 2 symmetrically installed at both ends of the installation block assembly 1, fixing nail bodies 3 symmetrically installed on both sides of the installation block assembly 1, the installation block assembly 1 and the fixing nail bodies 3 being connected by a connecting assembly 4, and the installation block assembly 1 and the film pressing rod assembly 2 being connected by an adjusting assembly 5.

[0025] The connecting component 4 includes a connecting seat 41, which is fixedly connected to both sides of the mounting block component 1. A square insert 42 is tightly inserted into the lower part of the connecting seat 41. A fixing rod 43 is tightly snapped into one side of the square insert 42. The fixing rod 43 and the connecting seat 41 are in close sliding connection. A pull block 44 is fixedly connected to one end of the fixing rod 43. Fixing springs 45 are provided on both sides of the fixing rod 43 located outside the connecting seat 41. One end of the fixing spring 45 is fixedly connected to the connecting seat 41, and the other end of the fixing spring 45 is fixedly connected to the pull block 44. A protective component 46 is sleeved on the surface of the fixing nail body 3.

[0026] By adopting the above technical solution, when the square insert 42 is inserted into the connecting seat 41 and the square insert 42 and the fixing rod 43 abut against each other, the fixing rod 43 will move to one side under the action of the guide slide at one end, so that the pull block 44 moves outward and stretches the fixing spring 45 until the square insert 42 moves to the fixing hole on one side and coincides with the fixing rod 43. The fixing spring 45 returns to its original position, and the fixing rod 43 is inserted into the fixing hole to fix the square insert 42, thereby completing the assembly of the fixing nail body 3. When disassembling, the fixing rod 43 and the square insert 42 can be separated by pulling.

[0027] Specifically, the two ends of the pull block 44 are slidably connected to a stabilizing slide rod 47. One end of the stabilizing slide rod 47 is fixedly connected to the connecting seat 41, and the other end of the stabilizing slide rod 47 is fixedly connected to a stop block 48.

[0028] By adopting the above technical solution, the stabilizing slide bar 47 facilitates the stable sliding of the pull block 44, and the stop block 48 facilitates the limitation of the movement range of the pull block 44.

[0029] Specifically, a guide slide is provided at one end of the fixing rod 43, and a fixing hole for matching the fixing rod 43 is provided on one side of the square insert 42.

[0030] By adopting the above technical solution, the guide slide facilitates the movement of the fixed rod 43 to one side when the square insert 42 and the fixed rod 43 come into contact, and the fixing hole facilitates the insertion of the fixed rod 43 to fix the square insert 42.

[0031] Specifically, the protective component 46 includes a support block 461, which is fixedly connected to the bottom of the square insert block 42. The upper surface of the support block 461 is in contact with the connecting seat 41. The middle part of the bottom of the support block 461 is fixedly connected to the fixing nail body 3. A positive magnetic strip 462 is fixedly connected to the lower surface of the support block 461. A negative magnetic strip 463 is attracted below the positive magnetic strip 462. A protective sleeve 464 is fixedly connected below the negative magnetic strip 463.

[0032] By adopting the above technical solution, the protective sleeve 464 is fixed by the positive magnetic strip 462 and the negative magnetic strip 463, so as to protect the fixing nail body 3 by the protective sleeve 464. When installing the fixing nail body 3, the protective sleeve 464 can be removed directly by separating the positive magnetic strip 462 and the negative magnetic strip 463.

[0033] Specifically, the protective sleeve 464 has a groove in the middle for fitting and inserting into the fixing nail body 3.

[0034] By adopting the above technical solution, the insertion groove facilitates the protective sleeve 464 to be fitted onto the surface of the fixing nail body 3 for protection.

[0035] In this embodiment, when the square insert 42 is inserted into the connecting seat 41, and the square insert 42 and the fixing rod 43 abut against each other, the fixing rod 43 will move to one side under the action of the guide slide at one end, causing the pull block 44 to move outward and stretch the fixing spring 45 until the square insert 42 moves to the fixing hole on one side and coincides with the fixing rod 43. The fixing spring 45 then returns to its original position, causing the fixing rod 43 to be inserted into the fixing hole and fix the square insert 42, thus completing the assembly of the fixing nail body 3. When disassembling, the fixing rod 43 and the square insert 42 can be pulled apart. The protective sleeve 464 is fixed by the positive magnetic strip 462 and the negative magnetic strip 463 to protect the fixing nail body 3. When installing the fixing nail body 3, the protective sleeve 464 can be removed directly by separating the positive magnetic strip 462 and the negative magnetic strip 463, so that the fixing nail body 3 can be easily disassembled and assembled during use.

[0036] Example 2

[0037] The difference between this embodiment and embodiment 1 is that, specifically, the adjusting component 5 includes an adjusting support 51, which is fixedly connected to both ends of the mounting block component 1. A bevel gear 52 is installed at one end inside the adjusting support 51. A throttle 53 is fixedly connected above the bevel gear 52. The throttle 53 and the adjusting support 51 are rotatably connected by a bearing. A bevel gear 54 is meshed with one side of the bevel gear 52. An adjusting trapezoidal screw 55 is fixedly connected to one end of the bevel gear 54. The adjusting trapezoidal screw 55 and the adjusting support 51 are rotatably connected by a bearing. An adjusting plate 56 is threadedly connected to the surface of the adjusting trapezoidal screw 55. The adjusting plate 56 and the adjusting support 51 are in close sliding connection.

[0038] By adopting the above technical solution, rotating the handle 53 causes the first bevel gear 52 to rotate. The rotation of the first bevel gear 52 causes the second bevel gear 54, which is meshed on one side, to rotate. The rotation of the second bevel gear 54 causes the adjusting trapezoidal screw 55 to rotate. The rotation of the adjusting trapezoidal screw 55 causes the adjusting plate 56 to move, thereby adjusting the position of the pressure rod assembly 2 through the adjusting plate 56.

[0039] Specifically, the surface of the throttle 53 is surrounded and fixedly connected with anti-slip strips, and one end of the adjusting trapezoidal lead screw 55 located inside the adjusting plate 56 is fixedly connected with a limit block.

[0040] By adopting the above technical solution, the anti-slip strip achieves the anti-slip effect, and the limiting block facilitates the limitation of the movement range of the adjustment plate 56.

[0041] In this embodiment, when the handle 53 is rotated, the handle 53 drives the first bevel gear 52 to rotate. The rotation of the first bevel gear 52 drives the second bevel gear 54, which is meshed with it on one side, to rotate. The rotation of the second bevel gear 54 drives the adjusting trapezoidal screw 55 to rotate. The rotation of the adjusting trapezoidal screw 55 drives the adjusting plate 56 to move. Thus, the adjusting plate 56 drives the pressure rod assembly 2 to adjust its position. This makes it easy to adjust the position of the pressure rod assembly 2 during use, improving the convenience of use.

[0042] The structure and working principle of the mounting block assembly 1, the film pressing rod assembly 2, and the fixing nail body 3 in this utility model have been disclosed in a film fixing device for agricultural greenhouses disclosed in Chinese patent application number 202323234527.4. Its working principle is as follows: the mounting block assembly 1 includes a mounting block, a pressing screw, a flipping side groove, a flipping rod, a fixing shaft, a top groove, and a connecting block; the film pressing rod assembly 2 includes a locking screw, a fixing rod, a film pressing rod, an end flipping groove, a pressing inner block, a connecting hole, a top buckle groove, an end insertion block, an end alignment hole, and a bottom insertion block; the mounting block is placed on the top surface of the soil layer, and after being pressed downwards, the fixing nail body 3 on the bottom surface is inserted into the soil layer and fixed in place. After the top extrusion screw rotates, the bottom extrusion block presses downwards, causing the extrusion flipping rod to flip and fix itself at a specified angle inside the flipping side groove. After the fixed rod is flipped to the specified angle, the side locking screw rotates, causing the extrusion inner block to press and fix itself on both sides of the fixed rod. Multiple film pressing rods are connected and extended by inserting bottom inserts at one end into the corresponding end holes, forming a multi-film pressing rod connection. The bottom insert of the fixed rod is inserted into the top buckle groove to complete the installation. After the extrusion screw is rotated, the extrusion fixing sleeve flips, causing the extended film pressing rod to press downwards onto both sides of the film to form a fixing effect.

[0043] The working principle and usage process of this utility model: This utility model is used to fix the inner film of agricultural greenhouses. In use, the fixing nail body 3 is installed through the connecting component 4. The position of the film pressing rod component 2 is adjusted through the adjusting component 5, thus enabling its use. When using the connecting component 4, the square insert 42 is inserted into the connecting seat 41. When the square insert 42 and the fixing rod 43 abut, the guide slide at one end of the square insert 42 will cause the fixing rod 43 to move to one side, causing the pull block 44 to move outward and stretch the fixing spring 45 until the square insert 42 moves to the fixing hole on one side and coincides with the fixing rod 43. The fixing spring 45 then returns to its original position, causing the fixing rod 43 to insert into the fixing hole, fixing the square insert 42, thus completing the assembly of the fixing nail body 3. To disassemble, simply pull the fixing rod 43 and the square insert 42 to separate them, using the positive magnetic strip 462. The protective sleeve 464 is fixed by the negative magnetic strip 463 to protect the fixing nail body 3. When installing the fixing nail body 3, the protective sleeve 464 is removed by directly separating the positive magnetic strip 462 and the negative magnetic strip 463. This allows for easy disassembly and assembly of the fixing nail body 3 during use. When using the adjustment component 5, rotating the handle 53 drives the first bevel gear 52 to rotate. The rotation of the first bevel gear 52 drives the second bevel gear 54, which is meshed on one side, to rotate. The rotation of the second bevel gear 54 drives the adjusting trapezoidal screw 55 to rotate. The rotation of the adjusting trapezoidal screw 55 drives the adjusting plate 56 to move. This allows the pressure rod assembly 2 to be moved and its position adjusted through the adjusting plate 56. This makes it easy to adjust the position of the pressure rod assembly 2 during use, improving the ease of use.

[0044] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
