[0002] The keel of a greenhouse is a building structure, usually made of light steel, which plays a supporting and fixing role. It is a key component of the greenhouse frame and determines the stability and service life of the greenhouse. The material, shape and installation method of the keel directly affect the overall performance and use effect of the greenhouse.

[0003] According to the publication (announcement) number: CN203027823U, the publication (announcement) date: 2013-07-03, a greenhouse double-film greenhouse is disclosed, including a keel, an inner film, an outer film and an inflatable bag; the inner film is laid on the keel, and the inflatable bag is two rectangular air bags connected side by side to form a double air bag, the connecting middle seam of the double air bag is aligned with the keel and laid on the inner film, and the outer film is laid on the inflatable bag. The keels are fixed to the ground by connecting parts to form a greenhouse frame, and the inner film, the inflatable bag and the outer film cover the greenhouse frame on the keel. The keels are fixed to the ground by connecting parts to form a greenhouse frame, and the greenhouse frame is combined with the wall to form a ground-standing greenhouse, and the inner film, the inflatable bag and the outer film cover the greenhouse frame on the keel.

[0018] In order to enable those skilled in the art to better understand the technical solution of the present invention, the present invention will be further described in detail below in conjunction with the accompanying drawings.

[0019] like Figure 1-2As shown, a keel structure used in a greenhouse includes a frame 1, a placement groove 10 is opened on the frame 1, a top support plate 19 is movably arranged on the placement groove 10, a cross beam 11 is arranged on the frame 1, a threaded groove 12 is opened on the cross beam 11, and a screw 20 is arranged in the inner thread of the threaded groove 12.

[0020] Specifically, when in use, the plastic film is covered on multiple frames 1. If the plastic film is too long, the screw 20 is rotated to make the screw 20 rotate on the beam 11, and the top support plate 19 on the placement groove 10 of the frame 1 is lifted up, and the excess plastic film is propped up on the frame 1 again, so that the greenhouse can be propped up with a convex arc to better receive sunlight, and the excess plastic film can also be utilized.

[0021] In the above scheme, the greenhouse is supported by multiple frames 1, the installation of the top support plate 19 is achieved through the placement groove 10 on the frame 1, the support of the excess plastic film is achieved through the top support plate 19, the frame 1 is supported by the cross beam 11 on the frame 1, and the top support plate 19 in the placement groove 10 is propped up by the screw 20 on the cross beam 11 to adapt to the length of the plastic film.

[0022] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, a support frame 13 is arranged on the skeleton 1, and a first plate member 14 and a second plate member 15 are symmetrically arranged between the support frame 13 and the skeleton 1.

[0023] Furthermore, a second shaft rod 17 is provided at the connection between the first plate 14 and the second plate 15 , and a first shaft rod 16 is provided at the connection between the first plate 14 and the frame 1 and the second plate 15 and the support frame 13 .

[0024] Specifically, when the screw 20 rotates on the cross beam 11 and lifts up the top support plate 19 on the placement slot 10 of the skeleton 1, the first plate 14 and the second plate 15 change from the sideways V-shape to the I-shape, and at the same time, the first shaft rod 16 and the second shaft rod 17 rotate to assist the first plate 14 and the second plate 15 to deform and support the lifting of the top support plate 19.

[0025] As an embodiment further provided by the present invention, according to Figure 1 and Figure 2 As shown, vertical rods 18 are symmetrically arranged on the frame 1 , and sliding grooves 181 are opened on the vertical rods 18 .

[0026] Furthermore, it includes a top support plate 19 , a slide rod 182 is slidably arranged in the slide groove 181 , and the other end of the slide rod 182 is arranged on the top support plate 19 .

[0027] Furthermore, a handle 21 is provided at the bottom of the screw rod 20 .

[0028] Specifically, when the screw rod 20 rotates on the cross beam 11 and lifts up the top support plate 19 on the placement groove 10 of the frame 1, it will also drive the slide rod 182 to slide upward in the slide groove 181 in the vertical rod 18 to prevent the top support plate 19 from shaking and provide reinforcement.

[0029] Working principle: When in use, cover the plastic film on multiple skeletons 1. If the plastic film is too long, rotate the screw 20 to make the screw 20 rotate on the crossbeam 11, lift the top support plate 19 on the placement groove 10 of the skeleton 1, and prop up the excess plastic film on the skeleton 1 again. At this time, the first plate 14 and the second plate 15 change from the sideways V shape to I shape, and the first shaft rod 16 and the second shaft rod 17 rotate to assist the first plate 14 and the second plate 15 to deform, support the lifting of the top support plate 19, and at the same time drive the slide rod 182 to slide upward in the slide groove 181 in the vertical rod 18 to prevent the top support plate 19 from shaking and reinforce it. The greenhouse will then support a convex arc to better receive sunlight, and the excess plastic film can also be utilized.
