Description

Technical Field

[0001] This utility model relates to the field of agricultural film technology, specifically to a stable fixing device for greenhouse film. Background Technology

[0002] Greenhouse films, by creating a sealed space, reduce heat loss while absorbing and slowly releasing solar radiation, maintaining a stable temperature inside the greenhouse. High-quality greenhouse films can have a light transmittance of over 90%, allowing visible light to pass through and providing crops with ample sunlight, enhancing photosynthetic efficiency. The films also block direct attacks from cold air, rain, and melting snow, reduce wind speed, and decrease the risk of crop damage from frost, waterlogging, and mechanical damage. In rainy seasons and typhoon-prone areas, greenhouse films can significantly reduce the probability of disease occurrence.

[0003] Patent document CN220359790U discloses a double-layer greenhouse film structure with a fixing device. This double-layer greenhouse film structure consists of two parts: a greenhouse film support and a greenhouse film fixing part. The support part consists of a greenhouse arch beam made of rectangular hollow square steel and a flexible multi-strand steel wire rope net. The fixing part consists of pressure strips, greenhouse film slots, and spring clips, and the above components, as well as the upper and lower layers of greenhouse film, are fixed together with the hollow square steel by self-tapping screws. This can effectively reduce heat loss from the greenhouse film surface and improve the heat preservation performance of the greenhouse. It has the characteristics of simple structure, easy installation, easy disassembly, and easy film replacement, and is suitable for the construction of greenhouses for agricultural and fishery farming in high-altitude and cold regions. However, this patent still has the following problems in actual use:

[0004] The double-layer greenhouse structure with fixing device uses self-tapping screws to fix the above components and the upper and lower layers of greenhouse film to the hollow square steel. During installation, the self-tapping screws can damage the greenhouse film when they pass through it, making the film prone to tearing and breaking when stretched. Therefore, the practicality of this double-layer greenhouse structure with fixing device is poor.

[0028] 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.

[0029] Please see Figures 1-5 This utility model provides a technical solution: a stable fixing device for greenhouse film, including a greenhouse film support 1; a greenhouse film body 2 is provided on one side of the greenhouse film support 1; it also includes: a connecting block 3 is provided at the upper end of the greenhouse film body 2, a pressing groove 4 is provided in the middle of the bottom of the connecting block 3, an anti-detachment block 5 is fixedly connected to one side of the pressing groove 4, and an anti-detachment groove 6 is provided on one side of the anti-detachment block 5; the pressing groove 4 fits into the upper end of the greenhouse film support 1, and the anti-detachment blocks 5 are symmetrically arranged on both sides of the greenhouse film support 1; the anti-detachment groove 6 is opened on the side of the anti-detachment block 5 away from the pressing groove 4, and the lower end of the anti-detachment block 5 and the anti-detachment... The inner side of the groove 6 is all set to be arc-shaped. By setting the pressing groove 4, the anti-detachment block 5 and the anti-detachment groove 6 at the bottom of the connecting block 3, the friction of the anti-detachment groove 6 is increased, which reduces the possibility of the connecting block 3 separating from the connecting frame 7. Furthermore, by squeezing the anti-detachment block 5, the friction between the pressing groove 4 and the outer side of the greenhouse film support 1 is increased, which further enhances the anti-detachment effect of the connecting block 3 and the connecting frame 7, making the fixing device more stable during use. Moreover, the arc-shaped surface setting helps to reduce the damage to the greenhouse film body 2 caused by the fixing device, thus making the service life of the greenhouse film longer.

[0030] The connecting frame 7 is provided below the greenhouse film body 2. A fixing groove 8 is provided on the inner side of one end of the connecting frame 7. An anti-slip block 9 is attached to the inner side of the fixing groove 8. A threaded hole 16 is provided in the middle of the other end of the connecting frame 7. The connecting frame 7 is C-shaped. The fixing groove 8 fits with the lower end of the anti-detachment block 5 and the inner side of the anti-detachment groove 6. The fit between the fixing groove 8 and the anti-slip block 9 and the anti-detachment groove 6 and the anti-detachment block 5 enhances the stability of fixing the greenhouse film body 2.

[0031] The fixed groove 8 has a sliding groove 10 on one side, a sliding block 11 is slidably connected to the middle of the sliding groove 10, a sliding seat 12 is fixedly connected to the top of the sliding block 11, a sliding groove 13 is formed on one side of the sliding seat 12, and a threaded rod 14 is rotatably connected to the other side of the sliding seat 12. A rotating handle 15 is fixedly connected to one end of the threaded rod 14. The sliding groove 10 is formed at the lower end of the connecting frame 7 away from the fixed groove 8, and the sliding seat 12 is set inside the connecting frame 7. The sliding groove 13 is formed on the side of the sliding seat 12 close to the fixed groove 8, and the sliding groove 13 fits with the lower end of the anti-detachment block 5 and the inner side of the anti-detachment groove 6. The threaded rod 14 is threadedly connected to the threaded hole 16; the inner side of the sliding groove 13 is fitted with an anti-slip block 9; the top surface of the greenhouse film body 2 is fitted with the inner side of the anti-detachment groove 6, the lower end of the anti-detachment block 5, and the inner side of the pressing groove 4; the bottom surface of the greenhouse film body 2 is fitted with the anti-slip block 9 on the inner side of the sliding groove 13, the top surface of the greenhouse film bracket 1, and the anti-slip block 9 on the inner side of the fixing groove 8. Through the connection of the connecting block 3 and the connecting frame 7, the situation of drilling holes in the greenhouse film body 2 is avoided, so that the greenhouse film body 2 remains intact, which makes it easier to reduce the tearing of the greenhouse film caused by pulling, thereby extending the service life of the greenhouse film and improving the stability of the greenhouse film.

[0032] Working principle: When using this stable film fixing device, first, the film body 2 is laid on the top surface of the film support 1.

[0033] Next, the connecting block 3 presses the greenhouse film body 2 onto the top surface of the greenhouse film support 1 through the pressing groove 4, so that the greenhouse film body 2 and the lower end of the anti-detachment block 5 are in contact.

[0034] Finally, the fixing groove 8 on one side of the connecting frame 7 is fitted with the anti-slip groove 6 through the anti-slip block 9. Then, by rotating the rotating handle 15, the rotating handle 15 drives the threaded rod 14 to rotate in the threaded hole 16, so that the sliding seat 12 slides in the sliding groove 10 through the sliding block 11, and the sliding groove 13 pushes the anti-slip block 9 to fit the greenhouse film body 2 with the anti-slip groove 6, thus achieving the fixing of the greenhouse film.

[0035] Although the present invention has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present invention should be included within the protection scope of the present invention.
