Description

Thin film protection groove

Technical Field

The utility model relates to a film protecting groove mainly provides one kind through the film protecting groove with the film be fixed in the draw-in groove in, can make the film avoid receiving the direct extrusion of jump ring and draw-in groove and warp or damaged.

Background

In the field of agricultural technology, greenhouse technology is widely applied to agricultural production. The film of the film greenhouse is fixed, generally, the film is covered on the clamping groove of the greenhouse framework, and the film is fixed in the clamping groove by using a clamp spring, as shown in fig. 6.

The jump ring is generally for having elastic steel wire or soaking the steel wire of moulding, and the draw-in groove material is galvanized steel sheet or aluminium generally, when fixing the film according to the mode of figure 6, because the stress position of draw-in groove and jump ring is comparatively concentrated, the film stress position is also comparatively concentrated, and the film easily receives the extrusion and warp. In addition, during installation, the installation of the tail part of the clamp spring is difficult due to large stress, and is generally completed by means of tools, such as pliers, a screwdriver and the like, when the tools are not used properly, the thin film is easy to contact with the tools and is damaged. When the clamp spring needs to be replaced, the head of the clamp spring is stressed greatly, so that the head of the clamp spring is generally required to be lifted by using a pair of pliers, a screwdriver and the like, and the thin film is easily damaged by the tools.

After the thin film is fixed, when the clamp spring generates rusty spots, the rusty spots can quickly corrode the thin film, so that the thin film is damaged.

After the film of the film greenhouse is deformed and damaged, when strong wind occurs, the film is easier to be damaged under the action of wind power, so that the service life of the film is shortened, the damage and the damage of the film can influence the performance of the greenhouse, and the growth of crops in the greenhouse is influenced.

Disclosure of Invention

In order to solve the shortcoming of the fixed film of current jump ring and draw-in groove, reduce the atress deformation that the film is fixed, make the fixed atress of film more even, avoid the instrument to cause the damage to the film, prevent jump ring corrosion damage film, the utility model provides a film protecting groove.

The utility model discloses a realize above-mentioned purpose, the technical scheme who adopts is: a thin film shield bath, comprising: the thin film protection groove is strip-shaped, the cross section structure of the thin film protection groove is that the upper end of the thin film protection groove is provided with two long panels, the two long panels are symmetrically arranged at intervals, the lower end of the thin film protection groove is provided with two short panels, the two short panels are symmetrically arranged at intervals, an arc-shaped convex surface is arranged between the corresponding ends of the two short panels, the two short panels and the arc-shaped convex surface are of an integrated structure, two inclined surfaces are arranged between the outer ends of the two short panels and the corresponding ends of the two long panels, the joint of the two inclined surfaces and the two short panels is an arc surface I, and the joint of the two inclined surfaces and;

the arc convex surface is soft convex surface, and two long panels and two short panels are hard boards, and two inclined planes, cambered surface I and cambered surface II are the hard face.

The utility model has the advantages that: reasonable and simple structure and convenient installation and use. When the film fixing clamp is used together with a matched metal clamping groove, the film can be fixed and stressed uniformly and is not easy to deform. When the film is assembled and disassembled, the film is not easy to be damaged by an assembling tool. When the clamp spring is corroded, the film is not affected.

Detailed Description

As shown in figure 1 of the drawings, in which, as shown in figure 2, the film protection groove 1 is strip-shaped, and the cross-sectional structure of the film protection groove is that the upper end is provided with two long panels 1-1, the two long panels 1-1 are symmetrically arranged at intervals, the lower end is provided with two short panels 1-2, the two short panels 1-2 are symmetrically arranged at intervals, an arc convex surface 1-3 is arranged between the corresponding ends of the two short panels 1-2, the two short panels 1-2 and the arc convex surface 1-3 are in an integral structure, two inclined surfaces 1-4 are arranged between the outer ends of the two short panels 1-2 and the corresponding ends of the two long panels 1-1, the joint of the two inclined surfaces 1-4 and the two short panels 1-2 is an arc surface I1-5, and the joint of the two inclined surfaces 1-4 and the two long panels 1-1 is an arc surface II 1-6.

The arc-shaped convex surfaces 1-3 are soft convex surfaces made of soft materials, the two long panels 1-1 and the two short panels 1-2 are hard plates made of soft materials, and the two inclined surfaces 1-4, the arc surfaces I1-5 and the arc surfaces II 1-6 are hard surfaces made of soft materials.

The film protective groove 1 can be made of polyvinyl chloride (PVC) or Polyethylene (PE) or polypropylene (PP) or Polystyrene (PS) or acrylonitrile-butadiene-styrene copolymer ABS or polyethylene terephthalate PET or rubber.

As shown in figures 3, 4 and 5, the using method comprises the steps of laying a film 2 on a clamping groove 3, arranging a film protection groove 1 and the clamping groove 3 on the film 2 correspondingly, arranging the same section of film 2 in the clamping groove 3 in parallel, arranging a rectangular fixed block 4 on an arc-shaped convex surface 1-3 in the film protection groove 1 along the length direction of the clamping groove 3, inserting one end of an L-shaped wrench 5 into a strip-shaped hole 4-1 of the fixed block 4, rotating the wrench 590 degrees clockwise or anticlockwise, rotating the fixed block 4 by 90 degrees simultaneously, expanding two inclined surfaces 1-4 outwards by the short surface ends at two sides of the fixed block 4, so that the arc-shaped convex surface 1-3 is expanded to be the same plane as the two short panels 1-2, at the moment, the plane at the bottom end of the film protection groove 1 presses a section of the film 2 on the plane in the clamping groove 3, the films at two sides of the section of the film 2 extend out of the clamping groove 3 and the film protection, and finally, clamping the clamp spring 6 in the film protection groove 1.
