Through the cooperation of the two first connecting blocks, two second connecting blocks, and the U-shaped block, the arc-shaped rod and the cylindrical connecting rod are connected. The U-shaped block is stuck on the arc-shaped rod, and the first and second connecting blocks abut against the cylindrical connecting rod, providing an installation base for the locking part and the expansion part, thereby firmly connecting the arc-shaped rod and the cylindrical connecting rod and ensuring the overall continuity of the greenhouse film support structure.

[0009] Furthermore, the first connecting block and the second connecting block are connected by four locking parts and four expansion parts.

[0010] Furthermore, the cylindrical connecting rod is provided with two first connecting blocks, and each of the two first connecting blocks is provided with a second connecting block on the side of the cylindrical connecting rod. A U-shaped block is slidably connected to the bottom of the two second connecting blocks. The two first connecting blocks and the two second connecting blocks abut against the cylindrical connecting rod, and the side of the U-shaped block near the cylindrical connecting rod abuts against the arc-shaped rod; wherein, the U-shaped block is stuck on the arc-shaped rod.

[0011] Furthermore, the locking part includes a locking assembly and a guide assembly. The locking assembly includes a hollow slide rod disposed on the second connecting block and the second connecting block. The top of the hollow slide rod has a threaded hole, and a threaded rod is threadedly connected to the threaded hole. An abutment is disposed on the threaded rod.

[0017] The beneficial effects of the overlapping component and greenhouse film overlapping device provided by this utility model are:

[0018] 1. By incorporating a locking mechanism consisting of a locking component and a guide component, the first and second connecting blocks are securely locked together through the cooperation of components such as a hollow sliding rod, a threaded rod, and a circular abutment. During installation, the threaded drive ensures a tight fit between the circular abutment and the first connecting block. Simultaneously, the guide component guarantees the stability and precision of the locking process, thus ensuring the strong connection between the cylindrical connecting rod and the arc-shaped rod. This effectively prevents loosening of the overlapping structure during use, improving the structural stability of the entire greenhouse film overlapping device. The locking and fixing of the first and second connecting blocks with the cylindrical connecting rod and arc-shaped rod can be quickly completed without complex operations, simplifying the installation steps and enhancing the convenience of the entire device's overlapping process.

[0019] 2. By setting up an expansion section, including an installation component and an expansion component, and utilizing the design of a spring telescopic rod and a trapezoidal block, the trapezoidal block will compress and contract to facilitate insertion during the insertion of the hollow slide rod into the first and second connecting blocks. After insertion, it can return to its original expansion under the action of the spring telescopic rod, so that the hollow slide rod is firmly locked onto the connecting block. This achieves the initial fixation of the connection between the first and second connecting blocks and the arc-shaped rod and cylindrical connecting rod, laying the foundation for the subsequent locking operation of the locking part, further enhancing the reliability of the connection between the various components of the overlapping part, and ensuring the structural strength of the entire device.

[0035] The following is combined with Figures 1-6 The technical solution provided by this utility model will be described in more detail.

[0036] This utility model provides an overlapping component and a greenhouse film overlapping device, including a base plate 111 and a plurality of arc-shaped rods 112 disposed on the top of the base plate 111. Two cylindrical connecting rods 113 are disposed on the plurality of arc-shaped rods 112, and a plurality of overlapping components are disposed on the two cylindrical connecting rods 113. A plurality of locking parts 2 and a plurality of expansion parts 3 are disposed above the base plate 111.

[0040] It is understandable that the locking part 2 and the expansion part 3 are used to connect the first connecting block 114 and the second connecting block 115, thereby enabling the rapid assembly of the first connecting block 114 and the second connecting block 115, which simplifies the installation steps and improves the convenience of the entire device assembly.

[0041] It should be noted that the two ends of the U-shaped block 116 are slidably mounted on the two second connecting blocks 115, thereby ensuring that the U-shaped block 116 and the arc rod 112 can be quickly engaged, improving the ease of connection.

[0042] Optionally, the two ends of the U-shaped block 116 are T-shaped blocks, and the second connecting block 115 is provided with a T-shaped groove.

The guide assembly 22 includes a plurality of cylindrical slide grooves 221 formed in the hollow slide bar 211. Sliding blocks 222 are slidably connected to the inner walls of the plurality of cylindrical slide grooves 221. Cylindrical slide bars 223 are fixedly connected to the tops of the plurality of sliding blocks 222. The side of the plurality of cylindrical slide bars 223 near the circular abutment 214 extends slidably to the outside of the hollow slide bar 211 and is fixedly connected to the circular abutment 214.

[0044] In some of the embodiments of this utility model described above, by setting the locking part 2, the locking and fixing between the first connecting block 114, the second connecting block 115, the cylindrical connecting rod 113, and the arc rod 112 can be quickly completed without complicated operations, which simplifies the installation steps and improves the convenience of the entire device assembly.

[0045] In some embodiments of this utility model, the expansion part 3 includes a mounting assembly 31 and an expansion assembly 32. The mounting assembly 31 includes a mounting groove 311 formed at the bottom of the hollow slide rod 211, and a rectangular block 312 is fixedly connected to the top inner wall of the mounting groove 311. The expansion assembly 32 is disposed on the rectangular block 312 and includes a plurality of spring telescopic rods 321 fixedly connected to the outer wall of the rectangular block 312. A trapezoidal block 322 is fixedly connected to the side of each of the spring telescopic rods 321 away from the rectangular block 312. The side of each of the trapezoidal blocks 322 away from the rectangular block 312 slides out of the hollow slide rod 211.

[0046] In some of the embodiments of this utility model described above, by providing the expansion part 3, the initial fixation of the connection between the first connecting block 114, the second connecting block 115 and the arc rod 112 and the cylindrical connecting rod 113 is achieved, laying the foundation for the subsequent locking operation of the locking part, enhancing the reliability of the connection between the various components of the overlapping part, and ensuring the structural strength of the entire device.

[0047] Example 1:

[0048] This utility model provides an overlapping component and a greenhouse film overlapping device. In use, several arc-shaped rods 112 are inserted in a linear array onto a base plate 111. Then, U-shaped blocks 116 are secured onto the arc-shaped rods 112. At this time, the two second connecting blocks 115 are also initially fixed by the U-shaped blocks 116. Next, cylindrical connecting rods 113 are placed on the two second connecting blocks 115, and two first connecting blocks 114 are placed on the two second connecting blocks 115 respectively. A hollow sliding rod 211 is then inserted. During insertion, several trapezoidal blocks 322 are compressed by the corresponding first connecting blocks 114. As the rectangular block 312 moves radially, several spring telescopic rods 321 are compressed until several trapezoidal blocks 322 retract into the hollow slide rod 211. The hollow slide rod 211 is then inserted into the corresponding first connecting block 114 and second connecting block 115 until the expansion portion 3 on the hollow slide rod 211 passes through the second connecting block 115. The spring telescopic rods 321 then rebound, causing several trapezoidal blocks 322 to reset. The trapezoidal blocks 322 and the circular abutment 214 cause the hollow slide rod 211 to lock onto the first connecting block 114 and the second connecting block 115.

[0049] After the hollow slide rod 211 is engaged with the first connecting block 114 and the second connecting block 115 by several trapezoidal blocks 322 and circular abutments 214, the hollow slide rod 211 is held by hand and the knob 215 is rotated. The knob 215 drives the threaded rod 213 to rotate on the threaded hole 212, thereby causing the threaded rod 213 to move axially toward the rectangular block 312, so that the circular abutment 214 moves toward the hollow slide rod 211. Guided by several cylindrical sliding grooves 221, sliders 222 and cylindrical slide rods 223, the circular abutment 214 moves toward the hollow slide rod 211 until its bottom surface abuts against the top of the first connecting block 114, thus completing the installation of one locking part 2. Similarly, the overlapping of the membrane frame can be completed by installing other arc-shaped rods 112, the first connecting block 114, the second connecting block 115 and the locking part 2.
