Abstract
The utility model discloses a greenhouse film fastening groove, which relates to the field of the protected agriculture greenhouse technology. The utility model is used to fasten greenhouse films. The groove adopts a long profile with a U-shaped section, the opening is inwardly concave, circular arc parts are arranged the both sides of the bottom, a tilted shoulders are arranged between the opening and the circular arc parts. The opening of the groove has slippery edges which roll inwardly. The rolling edge has an angle towards the direction the surface of the opening and the angle can be 20 degrees. When snap springs lock plastic films into the fastening grooves, the openings of the fastening grooves roll inwardly to ensure the snap springs to be not easy to leak, and when the rolling edge has an angle, the snap springs are further firmly fastened. When the snap springs are taken out, the snap springs are only required to be pressed down, the snap springs can be taken out by getting over the rolling edge, and the installation and operation are convenient.
Description
Affiliated technical field
The invention greenhouse film draw-in groove relates to the industrialized agriculture technical field, particularly the greenhouse engineering technology.
Background technology
In the industrialized agriculture technical field, greenhouse technology is used widely in agricultural production.In the Plastic film greenhouse engineering, the constant intensity of plastic film on the greenhouse framework directly influences the performance and the service life in greenhouse, and especially in the high wind area, the constant intensity of plastic film on the greenhouse framework is even more important.In the prior art, the mode of fixed plastics film has multiple, for example, adopts dovetail groove and form of springs; Adopt film groove, press strip, bar core form; Adopt draw-in groove, jump ring form.In the prior art, it is firm to have a solid film with draw-in groove, jump ring form fixed film, mounting or dismounting are convenient, do not damage the characteristics of film, but because the oral area of draw-in groove adopts the straight flange shape, in use the technological deficiency of Cun Zaiing is, under the high wind state, the possibility that still exists plastic film that jump ring is pulled out from draw-in groove.
Summary of the invention
In order to solve the technological deficiency that prior art exists, the purpose of the invention is, invents a kind of greenhouse film draw-in groove, can more effective fixed film, do not damage film, and fixedly thin film or plural layers easily, engineering construction is simple and convenient.
Above-mentioned purpose is achieved through the following technical solutions: the greenhouse film draw-in groove is rectangular section bar, and the draw-in groove cross section is the U font, receives in the oral area, two bottom sides is an arc sections, the shoulder that has inclination between oral area and the arc sections, the draw-in groove oral area has smooth flanging, and this flanging is to turnover in the draw-in groove.With respect to draw-in groove oral area plane, flanging is towards the draw-in groove bottom direction angle that tilts.The relative draw-in groove oral area of flanging plane inclination 20 degree angles.Draw-in groove one end has the grafting necking part.Draw-in groove bottom inner face has recessed impression.The draw-in groove material is a galvanized steel.
Owing to adopt technique scheme, in use, film is put into draw-in groove, plastic film is pressed into draw-in groove, make jump ring slide to the draw-in groove bottom along the shoulder that tilts by the elasticity of jump ring with jump ring, fix at circular arc position, draw-in groove bottom, circular arc restriction jump ring is deviate from from draw-in groove, in case of necessity, can use fixedly thin film of one or more jump rings, perhaps use two or three jump rings fixing plural layers respectively, to constitute the plural layers greenhouse.The draw-in groove oral area has smooth flanging, avoids damaging plastic film.To turnover, under high wind, when plastic film spurred jump ring from draw-in groove, flanging can further stop jump ring to this flanging in the draw-in groove, and the more effective jump ring that prevents is deviate from from draw-in groove.For the purpose of insurance more, can be with respect to draw-in groove oral area plane, make flanging towards the draw-in groove bottom direction angle that tilts, the 20 degree angles that tilt, the preferred relative draw-in groove oral area of flanging plane.When taking out jump ring, only jump ring need be pressed down, can cross flanging and take out, easy to install.Draw-in groove one end is made into necking part, makes it lucky driving fit and inserts another root draw-in groove other end, is convenient in construction work the tool free spreading draw-in groove section bar of just can pegging graft easily.Draw-in groove inner face bottom makes recessed impression along center line, the location of hold-down screw and penetrating in being convenient to construct, and recessed impression can be the recessed impression of consecutive rhombus.The design has solved the technological deficiency that prior art exists, and has obtained excellent technique effect.

Among the figure: 1. draw-in groove 2. arc sections 3. shoulders 4. flangings 5. bottoms 6. recessed impression 7. necking parts
Embodiment
In conjunction with Figure of description the greenhouse film draw-in groove is described further now.
Among Fig. 1, draw-in groove 1 cross section is the U font, receive in the oral area, 5 both sides, draw-in groove bottom are arc sections 2, jump ring is fixing in arc sections 2 with plastic film, owing to receive in the oral area, the restriction jump ring is therefrom deviate from, arc sections 2 can be held one or more jump rings, to satisfy fixedly one deck or multilayer plastic film requirement.Have shoulder 3 between oral area and the arc sections 2, the shoulder 3 of inclination connects oral area and arc sections 2 on the one hand, and the inner face of its inclination acts on jump ring on the other hand, makes jump ring enter arc sections 2 location, limits jump ring simultaneously and deviates from from draw-in groove 1.Draw-in groove 1 oral area has smooth flanging 4, avoids damaging in installation plastic film.To turnover, flanging 4 can stop further that jump ring deviates to this flanging 4 from draw-in groove under stressing conditions in the draw-in groove.With respect to draw-in groove oral area plane, flanging 4 further strengthens the effect that the restriction jump ring is deviate from towards the draw-in groove bottom 5 directions angle that tilts.Flanging 4 relative draw-in groove oral area plane preferred angled 20 degree angles.
Among Fig. 2, greenhouse film draw-in groove one end has necking part 7, for the usefulness of spreading draw-in groove section bar in using.Draw-in groove 1 bottom 5 inner faces are manufactured with recessed impression 6, be convenient to the hold-down screw nail is worn draw-in groove 1 in greenhouse construction, and the nail point are difficult for displacement when impacting screw.Draw-in groove 1 material adopts galvanized steel, corrosion in preventing to use.
Fig. 3 is greenhouse film draw-in groove inserting state figure, and draw-in groove 1 one ends have grafting necking part 7, when needing spreading draw-in groove section bar, only needs the necking part 7 of draw-in groove 1 one ends is inserted the end that another root draw-in grooves 1 do not have necking part 7, just spreading draw-in groove section bar easily.
