Problems solved by technology

[0002] The existing greenhouse mainly consists of two parts, one part is the support frame, and the other part is the heat preservation film covering the support frame. However, the circlips in the prior art are made of metal with a plastic cladding on the surface. The plastic cladding usually cracks and easily peels off with the service life, which causes the circlips to rust or even break. Rust powder friction between the film and the rust point of the circlip, and the sharp breakpoint of the circlip will damage the shed film, and even cause the shed to collapse
[0003] At the same time, in the prior art, the diameter of the circlip itself is smaller than the width of the slot, which causes the circlip to shift after it is installed in the slot, resulting in the inability of the shed film to be stretched straight, resulting in water accumulation

Embodiment 1

[0021] Such as Figure 1-3 As shown, a kind of membrane groove structure for greenhouses, including the groove body 1 of the membrane groove, the retaining spring 2 clamped in the groove body 1, the groove body 1 is a groove 3 with an opening outward, and the clamp The spring 2 is matched with the groove 3, and the circlip 2 is bent to form a continuous corrugated shape by polyester material. At the same time, the corresponding notch of the tank body 1 is a beveled surface 5 inclined from the outside to the inside, so that the circlip 2 can easily slide into the groove 3, which is convenient for installation. In addition, the circlip 2 is bent Form continuous centrally symmetrical figures, such as isosceles triangles, isosceles trapezoids, S-shaped, etc., so that the upper end 2-1 and lower end 2-2 of the circlip 2 are evenly stressed and clamped in the groove body 1 In order to avoid the deformation of the circlip 2 or the displacement of the shed film 4 due to uneven force ...

Embodiment 2

[0023] Such as Figure 4-6 As shown, a membrane groove structure for greenhouses, including the groove body of the membrane groove, the retaining spring clamped in the groove body, the groove body is a groove with an opening outward, and the retaining spring matches the groove , the circlip is bent from a polyester material to form a continuous corrugated shape, the upper and lower ends of the circlip correspond to the two ends of the groove respectively, and the upper and lower ends of the circlip are radially twisted Deformation, thereby increasing the lateral width of the upper end and lower end of the circlip, preventing the circlip from being displaced laterally in the groove, causing the shed film to shift, and the corresponding notch of the groove is inclined from outside to inside The oblique cut surface of the circlip makes it easy for the circlip to slide into the groove for easy installation. In addition, the circlip is bent to form a continuous centrally symmetrica...

Abstract

The invention relates to a clamping membrane groove structure for a greenhouse. The greenhouse comprises a groove body of a clamping membrane groove and a clamping spring which is clamped in the groove body, the groove body is a groove with an open facing outward, the clamping spring is matched with the groove, the clamping spring is made from a polyester material which is bent to form a continuous corrugated shape, and the upper end portion and the lower end portion of the corrugation corresponding to the clamping spring abut the two ends of the inside of the groove body. The structure uses the polyester material instead of an existing metal material, rust is prevented under the condition of ensuring the firmness and anti-aging properties, a greenhouse membrane is protected from damage, and the positions of the two ends of the clamping spring and the top and bottom of the groove body are torsionally deformed, thereby increasing the transverse width and preventing the clamping spring from shifting in a clamping groove to ensure the stability after the greenhouse membrane is installed and straightened.

Description

technical field [0001] The invention relates to the technical field of greenhouse erection and the application field of polyester materials, in particular to a film slot structure for a greenhouse. Background technique [0002] The existing greenhouse mainly consists of two parts, one part is the support frame, and the other part is the heat preservation film covering the support frame. However, the circlips in the prior art are made of metal with a plastic cladding on the surface. The plastic cladding usually cracks and is easy to peel off with the service life, which causes the circlips to rust or even break. Rust powder friction between the film and the rust point of the circlip, and damage to the sharp breakpoint of the circlip will damage the shed film, and even cause the greenhouse to collapse. [0003] At the same time, in the prior art, the diameter of the circlip itself is smaller than the groove width of the slot, which causes the circlip to shift after it is inst...
