[0002] Greenhouse, also known as warm house, refers to a room with cold-proof, heating and light-transmitting facilities for cultivating thermophilic plants in winter. It can provide growth period and increase yield in seasons not suitable for plant growth. It is mostly used for cultivating thermophilic vegetables, flowers, trees and other plants or raising seedlings in low temperature seasons. A greenhouse refers to a building that can control or partially control the growth environment of plants. It is mainly used for non-seasonal or non-regional plant cultivation, scientific research, generation breeding and ornamental plant cultivation.

[0003] To ensure that the greenhouse has sufficient light, the greenhouse frame is usually covered with a greenhouse film, and the greenhouse film needs to be fixed to the greenhouse frame through a fixing device.

[0037] like Figure 1-Figure 5 As shown, a greenhouse film fixing device comprises a film fixing sleeve 1, a film clamping strip 2 and a film mounting frame 3;

[0038] A fixing sleeve slot 4 is provided on the film mounting frame 3, and the film fixing sleeve 1 is snap-fitted and installed in the fixing sleeve slot 4. A film slot 5 is provided on the film fixing sleeve 1, and a film clip strip 2 is snap-fitted and installed in the film clip slot 5, and a space for snapping and fixing the greenhouse film 6 is formed between the film clip strip 2 and the film clip slot 5. Since the greenhouse film 6 is fixed between the film clip strip 2 and the film fixing sleeve 1, it does not directly contact the metal film mounting frame 3, and since the film fixing sleeve 1 and the film clip strip 2 are both made of plastic, they will not have hard contact with the greenhouse film 6, and thus will not damage the greenhouse film 6 during use, thereby increasing the service life of the greenhouse film 6. At the same time, since the greenhouse film 6 is fixed in the film fixing sleeve 1 through the film clip strip 2, the film fixing sleeve 1 is snap-fitted and fixed to the film mounting frame 3, and the film mounting frame 3 is installed on the greenhouse frame through bolts 8, thereby realizing convenient installation of the greenhouse film 6, and installation and replacement are convenient, fast and efficient.

[0039] like Figure 1-Figure 3As shown, the membrane fixing sleeve 1 includes a main body 101, and the main body 101 is in a U-shaped structure. The inner cavity of the U-shaped structure of the main body 101 forms a membrane clamping groove 5, and the main body 101 is clamped and installed in the fixing sleeve clamping groove 4. The inner wall of the U-shaped structure of the main body 101 is relatively provided with clamping groove portions 102, and the membrane clamping strip 2 is clamped and installed on the two clamping groove portions 102. In this embodiment, the opening end size of the U-shaped structure of the main body 101 is smaller than the size of the inner cavity of the U-shaped structure, so that the main body 101 can be clamped in the fixing sleeve clamping groove 4, and the clamping groove portion 102 is composed of two convex bulges arranged oppositely. When the protrusion 202 of the membrane clamping strip 2 is clamped into the two convex bulges arranged oppositely, the protrusion 202 is clamped by the convex bulge, and the membrane clamping strip 2 is conveniently clamped and fixed by setting the clamping groove portion 102.

Specifically, the main body 101, the inclined portion 103 and the support portion 104 are formed into an integrally formed plastic part. By using the integrally formed plastic part, processing is convenient and quick.

[0043] like Figure 1-Figure 2 and Figure 4 As shown, the membrane clamping strip 2 includes a main body 201, which is hollow and matches the inner cavity of the U-shaped structure of the main body 101. A protrusion 202 is relatively provided on the outer wall of the main body 201. The protrusion 202 is correspondingly provided to the slot 102 and is connected by a snap connection. By providing the protrusion 202, it is convenient for the membrane clamping strip 2 to be inserted into the slot 102 of the membrane fixing sleeve 1, thereby realizing the snap connection and fixation between the membrane clamping strip 2 and the membrane fixing sleeve 1.

Since the aperture of the open end of the fixed sleeve slot 4 is smaller than the aperture of the inner cavity, it is convenient for the fixed sleeve to be clipped and fixed in the fixed sleeve slot 4.

[0046] like Figure 1-Figure 4 As shown, the film fixing sleeve 1 and the film clamping strip 2 are both made of plastic material. Specifically, the film fixing sleeve 1 and the film clamping strip 2 are made of PVC material. By using plastic material, there will be no hard contact with the greenhouse film 6, thereby preventing the film fixing sleeve 1 and the film clamping strip 2 from damaging the greenhouse film 6 when clamping and fixing the greenhouse film 6.

[0047] like Figure 1 and Figure 5 As shown, the membrane mounting frame 3 includes a profile body 301, the profile body 301 is made of metal, a fixed sleeve slot 4 is arranged at one end of the profile body 301, and the other end of the profile body 301 is provided with a connecting groove 302 which is flanged toward the fixed sleeve slot 4 and is open, a connecting plate 7 is provided in the connecting groove 302, both ends of the connecting plate 7 are inclined, and bolts 8 are passed through the connecting plate 7, which pass through the connecting groove 302 and are connected to the greenhouse frame. By setting the connecting groove 302 and the connecting plate 7, it is convenient to install the membrane mounting frame 3 on the greenhouse frame. At the same time, through the above structure, the position of the connecting plate 7 in the connecting groove 302 can be adjusted along the length direction of the membrane mounting frame 3, and the installation is convenient and quick.

[0048] For ease of understanding, the working process of this embodiment is given below:

[0049] like Figure 1-Figure 5 As shown, first, place the connecting plate 7 with the bolt 8 in the cavity of the profile body 301, and pass the bolt 8 through the connecting groove 302. By adjusting the position of the connecting plate 7, the bolt 8 can be connected to the greenhouse frame, thereby fixing the film mounting frame 3 on the greenhouse frame. After that, the film fixing sleeve 1 is clamped and fixed in the fixing sleeve clamping groove 4 of the film mounting frame 3. After that, place the greenhouse film 6 on the surface of the film fixing sleeve 1, and clamp the film clamping strip 2 in the film clamping groove 5 of the film fixing sleeve 1. In the process of clamping and fixing the film clamping strip 2 and the film fixing sleeve 1, the greenhouse film 6 is squeezed and fixed between the film clamping strip 2 and the film clamping groove 5, thereby realizing the rapid fixation of the greenhouse film 6. Moreover, since the film fixing sleeve 1 and the film clamping strip 2 are made of plastic material, the damage of the greenhouse film 6 to the film fixing sleeve 1 and the film clamping strip 2 during the clamping and fixing process is effectively avoided.

[0050] In summary, the utility model provides a greenhouse film fixing device, which can conveniently fix the greenhouse film, is not easy to damage the greenhouse film, and has a long service life.
