Description

Locking means is fixed to canopy membrane

Technical Field

The utility model relates to an agricultural apparatus field.

Background

Because the greenhouse has the advantages of good heat preservation, high light transmittance, long service life and the like, the greenhouse is gradually accepted by farmers, the greenhouse is often used for carrying out heat insulation and heat preservation and other treatments on vegetables or flower seedlings in flower cultivation, vegetable planting or seedling breeding, the greenhouse is generally of an arch structure and mainly comprises a greenhouse framework and heat preservation plastic films fixed on the greenhouse framework, the greenhouse is composed of transverse arch support beams and longitudinal support beams, in order to prevent the heat preservation plastic films from separating from the greenhouse framework when wind blows, the fixing force between the heat preservation plastic films and the greenhouse framework should be enhanced, particularly the fixing between the greenhouse films and the greenhouse framework should be ensured at two ends of the greenhouse, but the existing greenhouse usually ignores the point, so that the greenhouse is easily blown out by the wind, and a novel greenhouse film fixing and locking device is researched and designed aiming at the existing problems, it is necessary to overcome the problems in the prior art for fixing the greenhouse in the market.

SUMMERY OF THE UTILITY MODEL

In order to solve the above-mentioned problem that current canopy membrane fixing device exists, the utility model provides a locking means is fixed to canopy membrane.

The utility model discloses a realize that the technical scheme that above-mentioned purpose adopted is: the utility model provides a locking means is fixed to canopy membrane, sets up between interior canopy skeleton and outer canopy skeleton, including fixed plate, locking flashboard, spring and film winding rod, the fixed plate is L shape, and the vertical section and the interior canopy skeleton of fixed plate are connected, the horizontal segment swing joint locking flashboard lower extreme of fixed plate, the other end of locking flashboard are equipped with hook portion, the vertical section of spring coupling fixed plate and the vertical section of locking flashboard.

The horizontal segment of fixed plate is equipped with the fixing base, and the fixing base passes through the bolt to be connected with the one end rotation of locking flashboard.

Still including setting up the oblique curved ejector pin on outer canopy skeleton, the oblique curved ejector pin is located the locking flashboard top, and the oblique curved ejector pin includes oblique curved portion and vertical portion, and the contained angle of oblique curved portion and vertical portion is 120 degrees.

The utility model discloses a locking means is fixed to canopy membrane does not need artificial operation, device simple structure, and the cost of manufacture is low, and the installation of being convenient for, comes suddenly temporarily at strong wind in addition, and the device can be with the good canopy body facility of very short time protection in the very first time.

fig. 3 is a partial enlarged view of fig. 2B according to the present invention;

fig. 4 is a schematic diagram of the work flow structure of the present invention.

In the figure: 1. the device comprises a fixing plate, 2, a locking flashboard, 3, a fixing seat, 4, a spring, 5, a bolt, 6, a film rolling rod, 7, an oblique bent ejector rod, 7-1, an oblique bent part, 7-2, a vertical part, 8, a shed film, 9, an inner shed framework, 10 and an outer shed framework.

Detailed Description

The utility model discloses a locking means is fixed to canopy membrane is as shown in fig. 1-3, sets up between the interior canopy skeleton 9 and the outer canopy skeleton 10 of big-arch shelter, including fixed plate 1, locking flashboard 2, spring 4 and film winding rod 6, fixed plate 1 is L shape, and the vertical section and the interior canopy skeleton 9 of fixed plate 1 are connected, the 2 lower extremes of horizontal segment swing joint locking flashboard of fixed plate 1, preferred, the horizontal segment of fixed plate 1 can be equipped with fixing base 3, and fixing base 3 can rotate with locking flashboard 2 through bolt 5 and be connected, the rotation of the locking flashboard 2 of being convenient for. The other end of the locking flashboard 2 is provided with a hook part. Spring 4 connects the vertical section of fixed plate 1 and the vertical section of locking flashboard 2, and between the hook portion of film rolling rod 6 ability joint fixed plate 1 and locking flashboard 2, preferred, hook portion of locking flashboard 2 can the downwarping, makes the device can be better block film rolling rod 6, lets whole device more reliable. The preferred device also comprises an oblique bent ejector rod 7 arranged on the outer shed framework 10, the oblique bent ejector rod 7 is positioned above the locking flashboard, the oblique bent ejector rod 7 can comprise an oblique bent part 7-1 and a vertical part 7-2, and preferably, the included angle between the oblique bent part 7-1 and the vertical part 7-2 is 120 degrees.

During actual use, a greenhouse film fixing and locking device is respectively arranged at two ends of a greenhouse head and a greenhouse tail of a greenhouse, multi-point 120-degree obliquely bent top rods 7 are distributed in longitudinal intervals of the film rolling rods 6, as shown in fig. 4, when strong wind blows, the film rolling rods 6 connected with greenhouse films 8 move downwards along vertical parts 7-1 of the obliquely bent top rods 7 and contact with the upper parts of hook parts of the movable rods 2, the locking flashboards 2 are opened under the action of gravity, the film rolling rods 6 enter the space between the locking flashboards 2 and the fixed plates 1, the locking flashboards 2 are pulled back under the action of elasticity of springs 4, the film rolling rods 6 are hooked by the hook parts of the locking flashboards 2, so that the whole greenhouse film 8 cannot be damaged in the strong wind, and the whole greenhouse body facility can be protected in the first time in case of sudden arrival of the strong wind.
