DETAILED DESCRIPTION

[0022] In order to make the purpose, technical scheme and advantages of the utility model more clear and obvious, the utility model is further described in detail below by combining with the drawings and examples.

[0023] Example one

[0024] As Figure 1 , Figure 2 and Figure 4The utility model provides a kind of hoop, comprising: the first clamping piece 110 and the second clamping piece 120 of symmetrical arrangement, the lower end of the first clamping piece 110 and the second clamping piece 120 is connected, in the embodiment, the first clamping piece 110 and the second clamping piece 120 are integrally arranged, and the hoop 100 is integrally stamped.

[0025] The middle part of the first clamping piece 110 and the second clamping piece 120 extends in the direction away from each other to form a clamping part 112, the clamping part 112 is provided with an arc-shaped groove matched with the outer surface of the arch rod 200, the arc-shaped groove can closely fit the elliptical arch rod 200, increase the contact area, improve the friction and connection stability. Second mounting hole 1121 is opened on both sides of the clamping part 112, and fasteners such as bolts 600 and self-tapping screws 500 can be used to further connect the hoop 100 and the arch rod 200 through the second mounting hole 1121.

[0026] In the embodiment, the cross section of the clamping part 112 is U-shaped, the bottom surface and the side surface of the clamping part 112 are fitted with the elliptical arch rod 200, and the fixing effect of the arch rod 200 and the hoop 100 is improved. And the hoop body is made of high-strength steel material, which not only ensures sufficient strength, but also has good corrosion resistance, and can adapt to the humid environment of greenhouse.

[0027] The lower part of the first clamping piece 110 and the second clamping piece 120 forms an adjusting space 111, and the lower part of the first clamping piece 110 and the second clamping piece 120 is provided with a first mounting hole 1111. The first mounting hole 1111 is used for installing the suspender 400, and the distance between the first clamping piece 110 and the second clamping piece 120 is reduced after the suspender 400 is installed and locked by the bolt 600, so that the clamping force of the clamping part 112 on the arch rod 200 is further improved. In the embodiment, the longitudinal section edge of the adjusting space 111 is V-shaped. The V-shaped structure is simple and convenient for production, and the two sides of the V-shaped structure are flat and convenient for the installation of the suspender 400.

[0028] The top of the first clamping piece 110 and the second clamping piece 120 is bent in the direction away from each other to form a horizontal connecting part 113. The third mounting hole 1131 is opened on the horizontal connecting part 113. The horizontal connecting part 113 is arranged in parallel with the horizontal plane, and after the horizontal rod 300 is installed on the horizontal connecting part 113, an enclosed shape is formed with the clamping part 112, further improving the clamping effect on the arch rod 200.

[0029] The utility model also discloses a kind of hoop connecting structure, comprising: arch rod 200, suspender 400, horizontal rod 300 and hoop 100, the cross section of arch rod 200 is elliptical, and arch rod 200 is installed in clamping part 112, the surface of first clamping piece 110 and second clamping piece 120 is tightly attached to arch rod 200, and self-tapping nail is used to pass through second mounting hole 1121, to fix hoop 100 on arch rod 200.

[0030] The crossbar 300 is fixedly connected to the horizontal connecting part 113. The crossbar 300 has a sliding groove. The crossbar 300 and the horizontal connecting part 113 are connected by bolts 600. The third mounting hole 1131 on the horizontal connecting part 113 is a bolt 600 hole for mounting bolts 600.

[0031] The boom 400 is installed at the lower part of the clamp 100. A mounting part 410 is provided at the top of the boom 400. The mounting part 410 is flat and made of the same material as the boom 400. A fourth mounting hole is provided on the mounting part 410. During installation, a bolt 600 is passed through the fourth mounting hole and the first mounting hole 1111, then a washer is placed, and the nut 610 is tightened to complete the connection between the boom 400 and the clamp 100. After the boom 400 is installed, the tightening of the bolt 600 and nut 610 reduces the adjustment space 111, causing the first clamping plate 110 and the second clamping plate 120 to move closer together. This further tightens the clamping part 112 around the arch rod 200, thereby enhancing the overall stability and reliability of the structure.

[0032] This utility model also discloses a greenhouse, including: a greenhouse support frame, which includes multiple sets of clamp connection structures. The clamp connection structure 100 of this solution solves the problem of effective connection between the roof crossbar 300 and the lower hanging rod 400 and arch rod 200 of a ridge-mounted, windowless greenhouse, thereby greatly improving the stability of the connection between the clamp 100 and the arch rod 200, effectively resisting the impact of severe weather such as strong winds and blizzards on the greenhouse structure, and extending the service life of the greenhouse.

[0033] Example 2

[0034] like Figure 3 The main difference between this embodiment and Embodiment 1 is that the adjustment space 111 has a U-shaped longitudinal section edge. The U-shaped structure has a similar function to the V-shaped structure, which allows the first and second spring pieces to maintain a certain distance. Thus, when the adjustment space 111 becomes smaller, the clamping force of the lower part of the clamping part 112 on the arch rod 200 is increased.

[0035] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any changes or substitutions that can be easily conceived by those skilled in the art within the technical scope disclosed in the present utility model should be included within the protection scope of the present utility model.
