Description

Technical Field

[0001] This utility model relates to a film-clamping component for greenhouses, belonging to the field of greenhouse technology. Background Technology

[0002] Greenhouses, due to their ease of construction, convenient use, and low investment, have been widely adopted by countries around the world with the development of the plastics industry. Plastic greenhouses use a film and frame to create a warm environment. A film-clamping assembly is needed to secure the film to the frame. Existing greenhouse film-clamping assemblies mainly use S-shaped wire metal spring clips pressed into metal slots. However, the spring clips in this method are prone to popping out, failing to achieve a more secure hold. To address this shortcoming, our company provides a new film-clamping assembly. Utility Model Content

[0003] The purpose of this utility model is to address the shortcomings of existing technologies by proposing a film-clamping component for greenhouses.

[0004] To achieve the above objectives, the present invention adopts the following technical solution: a film-clamping component for greenhouses, comprising a first component and a second component, wherein the second component is a long strip structure and has a slot along its extension direction, and the first component is clamped into the slot; The first component includes a top plate portion located at the top, and a first connecting portion extending downward is provided at the middle of the lower surface of the top plate portion, the bottom of the first connecting portion being connected to the center of the top of the snap-fit ​​plate portion; The snap-fit ​​plate portion is arranged parallel to the top plate portion; The second component includes a bottom plate portion located at the bottom, the bottom plate portion being a long plate-shaped structure, and second connecting portions extending upward on the top left and right sides of the bottom plate portion, and pressing portions extending outward on the top of the second connecting portions; The pressing part is arranged parallel to the bottom plate part; The pressing portions on both sides, the second connecting portions on both sides, and the top of the base plate form the slot; The base plate is provided with multiple threaded holes, and screws for connecting to the greenhouse frame are installed in the threaded holes.

[0005] Furthermore, the first component is a short block structure.

[0006] Furthermore, the distance A between the two pressing parts is 1-2 mm greater than the sum of the width G of the first connecting part and the thickness of the film on the left and right sides.

[0007] Furthermore, the distance B between the second connecting parts on both sides is 1-2 mm larger than the sum of the left-right dimension H of the snap-fit ​​plate and the thickness of the film on both sides.

[0008] Furthermore, the top dimension C of the pressing part to the bottom plate part is 1-2 mm larger than the height dimension E of the snap-fit ​​plate part plus the sum of the thickness of the film on the upper and lower sides.

[0009] Furthermore, the dimension F between the snap-fit ​​plate and the top plate is 1-2 mm larger than the sum of the height dimension D of the pressing part and the thickness of the film on the upper and lower sides.

[0010] Furthermore, a rubber pad is provided on the mating surface between the first component and the second component, and the rubber pad is connected to the respective component by nail-free adhesive.

[0011] Furthermore, the rubber pad has a thickness of 1 mm.

[0012] The positive effects of this utility model are as follows: 1. By pressing the film together with two tightly interlocking components, the film is tightly adhered to the gap, avoiding the phenomenon of the spring clip popping out in the traditional structure, and the film is more stable.

[0013] 2. The bonding surface is equipped with a rubber pad, which is 1 mm thick. The rubber pad can act as a buffer when clamping the greenhouse film to avoid damaging the film, and at the same time increase the friction with the film. Attached Figure Description

[0016] Please see Figures 1 to 4The present invention provides a technical solution: a film clamping component for greenhouses, comprising a first component 1 and a second component 2, wherein the second component 2 is a long strip structure and has a clamping groove along its extension direction, and the first component 1 is clamped into the clamping groove. The first component 1 includes a top plate portion 11 located at the top, and a first connecting portion 12 extending downward is provided at the middle of the lower surface of the top plate portion 11. The bottom of the first connecting portion 12 is connected to the center of the top of the snap-fit ​​plate portion 13, and the snap-fit ​​plate portion 13 is arranged parallel to the top plate portion 11. The second component 2 includes a bottom plate 21 located at the bottom. The bottom plate 21 is a long plate-shaped structure. The top left and right sides of the bottom plate 21 are provided with second connecting parts 22 extending upward. The top of the second connecting parts 22 is provided with pressing parts 23 extending to the opposite side. The pressing parts 23 are arranged parallel to the bottom plate 21. The first component 1 and the second component 2 can be set to the same width to facilitate the perfect shape. Both the first component 1 and the second component 2 are aluminum profiles, but the first component 1 is a short block structure. Since the second component 2 is longer, the first component 1 can be set to multiple dispersed arrangements. The pressing portions 23 on both sides, the second connecting portions 22 on both sides, and the top of the base plate portion 21 form the aforementioned slot; Multiple threaded holes are provided in the base plate 21, and screws 3 that connect to the greenhouse frame 4 are provided in the threaded holes. The greenhouse frame 4 is drawn in an abbreviated manner, and it can be any connection position between the greenhouse frame and the greenhouse film 5.

[0017] To illustrate the connection requirements between the first component 1 and the second component 2 in this scheme, please refer to... Figure 4 The distance A between the two holding parts 23 is 1-2 mm larger than the sum of the width G of the first connecting part 12 and the thickness of the film 5 on the left and right sides; The distance B between the second connecting parts 22 on both sides is 1-2mm larger than the sum of the left and right dimensions H of the snap-fit ​​plate part 13 and the thickness of the greenhouse film 5 on both sides; The top dimension C of the pressing part 23 to the bottom plate part 21 is 1-2 mm larger than the height dimension E of the snap-fit ​​plate part 13 plus the thickness of the upper and lower sides of the film 5. The dimension F between the snap-fit ​​plate part 13 and the top plate part 11 is 1-2 mm larger than the sum of the height dimension D of the holding part 23 and the thickness of the film 5 on both sides, that is, 0.5-1 mm larger on each side. After assembly, a relatively tight connection is formed. This solution uses two tightly inserted components to press the film together, so as to achieve a tight fit between the film and the gap, avoiding the phenomenon of the snap spring popping out in the traditional structure, and making the film clamping more stable.

[0018] Since both the first component 1 and the second component 2 are made of metal, in order to avoid damage to the greenhouse film 5, a rubber pad 14 / 24 with a thickness of 1 mm is provided on the bonding surface between the first component 1 and the second component 2. The rubber pad 14 / 24 is connected to the respective component by nail-free adhesive. After setting the rubber pads 14 / 24, the dimensions of the mating surfaces of the first component 1 and the second component 2 need to be adjusted to ensure that each side is 0.5-1mm larger, so that the first component 1 can be smoothly installed onto the second component 2.

[0019] Rubber pads 14 / 24 are provided on the bonding surface. The rubber pads are 1 mm thick and can act as a buffer when clamping the greenhouse film 5 to avoid damaging the greenhouse film. They can also increase the friction between the rubber pads and the greenhouse film.

Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely preferred examples and are not intended to limit the utility model.
