[0008] In some schemes, the cross section of the dew collecting groove is V-shaped, U-shaped or circular arc-shaped.

[0009] In some schemes, the included angle between the bottom surface of the snap spring groove and the horizontal plane is 0 to 90 degrees.

[0010] In some schemes, the clamping strip is wave-shaped.

[0011] In some schemes, the clamping strip is provided with a removal part, and the amplitude of the removal part is greater than the width of the snap spring groove.

[0012] In some schemes, the two inner side surfaces of the snap spring groove are respectively provided with inwardly extending limiting parts.

[0022] The application will be described in further detail below in conjunction with the drawings and specific embodiments, but the scope of protection of the application is not limited to the content described.

[0023] In order to avoid that the steel frame of the multi-span film greenhouse is wetted by the condensed water condensed on the inner side of the plastic film 6.

[0024] Please refer to Figure 1 and Figure 2 The application provides a plastic film connecting piece of multi-span film greenhouse, which comprises a body 1; the side top of the multi-span film greenhouse gutter 4 is inwardly bent to form a connecting surface.

[0025] The main body 1 is provided with a snap ring groove 11 and a condensation collection tank 12. The condensation collection tank 12 is located on one side of the snap ring groove 11, and the projection of the snap ring groove 11 on the horizontal plane and the projection of the condensation collection tank 12 on the horizontal plane do not overlap. A clip 2 for holding the plastic film 6 is installed in the snap ring groove 11.

[0026] In use, the main body 1 is fixedly installed on the connecting surface by welding, bolting, or other methods. Specifically, the bottom surface of the spring clip groove 11 is placed on the connecting surface, and then the main body 1 is firmly connected to the gutter 4 of the multi-span film greenhouse by welding. At this time, the condensation collection tank 12 is located on the right side near the arch of the multi-span film greenhouse, that is, on the side where the plastic film 6 extends. The edge of the plastic film 6 is embedded in the spring clip groove 11, and then the clip strip 2 is inserted to firmly connect the plastic film 6 to the main body 1. The plastic film 6 is easy to install. Preferably, the plastic film 6 completely covers the spring clip groove 11, that is, the edge of the plastic film 6 passes through the spring clip groove 11 and then extends a distance towards the gutter 4 of the multi-span film greenhouse to avoid rainwater wetting the spring clip groove 11, which helps to improve the service life of the main body 1.

[0027] In this way, when it rains, the rainwater that falls onto the plastic film 6 flows along the plastic film 6 to the gutter 4 of the multi-span film greenhouse, and then the gutter 4 draws the rainwater away. The dew that condenses on the inside of the plastic film 6 flows along the plastic film 6 to the dew collection tank 12, and then the dew collection tank 12 draws the dew away. This effectively avoids the technical problem of severe corrosion of the steel frame caused by dew wetting the steel frame of the multi-span film greenhouse, and effectively improves the service life of the steel frame of the multi-span film greenhouse.

[0028] In some specific embodiments, the cross-section of the condensate collection tank 12 is V-shaped, U-shaped, or arc-shaped, or it can be other trough-shaped structures that can drain water.

[0029] In some specific embodiments, the angle between the bottom surface of the spring clip groove 11 and the horizontal plane (∠A in the figure) is 0 degrees to 90 degrees, such as 30 degrees, 45 degrees, 60 degrees or any angle between 0 degrees and 90 degrees, which is conducive to rainwater flowing into the gutter 4 of the multi-span film greenhouse after crossing the spring clip groove 11, effectively reducing the water accumulation in the spring clip groove 11.

[0030] In some specific implementations, such as Figure 3 As shown, the clip 2 is wavy, and its amplitude matches the width of the snap ring groove 11. When installing the clip 2, it can be stretched to deform it, thereby reducing its width and making it easier to insert into the snap ring groove 11, which effectively improves the installation efficiency of the clip 2.

[0031] In the embodiment, the card strip 2 is provided with a taking-out part 21, the amplitude of the taking-out part 21 is greater than the width of the card spring groove 11, thus, when the card strip 2 is installed, the taking-out part 21 extends out of the card spring groove 11, which is beneficial to the dismounting of the card strip 2.

[0032] In the embodiment, the two inner side top parts of the card spring groove 11 are respectively provided with inwardly extending limiting parts 13, thus, after the card strip 2 is clamped into the card spring groove 11, the setting of the limiting parts 13 mechanically limits the card strip 2, effectively avoids the technical problem that the card strip 2 is pulled out when the plastic film 6 is pulled by a greater force, and improves the connection firmness of the plastic film 6 and the body 1.

[0033] The above has described the embodiments of the utility model, the above description is exemplary, is not exhaustive, and is not limited to the disclosed embodiments. Many modifications and changes are obvious to those skilled in the art without departing from the scope and spirit of the described embodiments. The selection of the terms used herein is intended to best explain the principles of the embodiments, practical application or improvement to the technology in the market, or to enable other ordinary skilled in the art to understand the embodiments disclosed herein.
