Detailed Implementation

[0025] The present invention will be further described below with reference to the accompanying drawings and specific embodiments.

[0026] Example 1

[0027] This utility model discloses a column head connector 100 for greenhouse frames, used to connect the uprights 200, arches 300, and water troughs 400 of the greenhouse frame. Figure 1 As shown, the column head connector 100 includes a vertically arranged column connecting plate 110 and two arch rod clamping plates 120. A first mounting through hole 111 is formed on the surface of the column connecting plate 110. The two arch rod clamping plates 120 are respectively fixedly connected to the column connecting plate 110, thus forming a socket 140 between the column connecting plate 110 and the arch rod clamping plates 120. The cross-sectional shape of the socket 140 is U-shaped, and the size of the socket 140, i.e., the gap between the two arch rod clamping plates 120, is slightly larger than the diameter of the arch rod 300. The socket 140 has space for inserting the end of the arch rod 300. A second mounting through hole 121 is formed on the surface of the arch rod clamping plate 120. The second mounting through hole 121 is threaded and communicates with the socket 140. Several ear plates 130 are also fixedly arranged along the upper edge of the arch rod clamping plate 120. These ear plates 130 are used to fix the water tank 400.

[0028] like Figure 2 , 3As shown, the column head connector 100 is used in pairs during installation. During installation, bolts, rivets, and other fasteners are first used to place the two opposing column head connectors 100 on the upper end of the column 200 through the first mounting through hole 111 and the pre-set mounting holes on the column 200. This forms a Y-shaped structure with sockets 140 on both sides, supporting the water tank 400 at the top. Then, the end of the arch rod 300 is inserted into the corresponding socket 140, and bolts are used to lock the end of the arch rod 300 into the socket 140 using the second mounting through hole 121. The water tank 400 is then placed above the column 200, engaging between the two column head connectors 100. The water tank 400 and the ear plate 130 are then fixedly connected using methods such as slot engagement and bolt splicing.

[0029] Compared to traditional connectors, the column head connector 100 has multiple connection functions, which can ensure the stable connection of the column 200, arch rod 300 and water tank 400, and build a complete mechanical support system to ensure the greenhouse's wind and earthquake resistance under severe weather conditions.

[0030] Its column connecting plate 110 can be matched with columns 200 of various cross sections and sizes, and the U-shaped socket 140 can be adapted to arch rods 300 with different curvatures. The overall installation is highly flexible and versatile, which can effectively reduce material waste and construction delays caused by compatibility issues.

[0031] Moreover, the column head connector has a simplified structure, eliminating the need for complex welding or tedious splicing during installation. This significantly shortens construction time, reduces construction difficulty, and improves the safety and efficiency of greenhouse frame construction. The material cost is relatively low, and the later maintenance is less difficult.

[0032] In this embodiment, at least two first mounting through holes 111 and two mounting through holes 121 are provided for locking to ensure a firm connection between the column head connector 100 and the column 200 and the arch rod 300. The first mounting through holes 111 are arranged vertically at intervals, and the second mounting through holes 121 are arranged along the axial direction of the arch rod 300.

[0033] Two or more ear plates 130 are also provided on the side of the arch rod clamp plate 120 opposite to the insertion port 140. Their positions correspond to the side wall and bottom of the water tank 400, which can stably support and limit the water tank 400. The ear plate 130 has a third mounting through hole 131, which can be connected to the pre-set mounting hole on the water tank 400 by bolt splicing. With the help of rubber sealing gasket, a stable connection with the water tank 400 is achieved. Similarly, several support plates 150 are also provided on the upper edge of the arch rod clamp plate 120. The upper side of the support plate 150 corresponds to the outer wall of the water tank 400, which can help the ear plate 130 support the water tank 400.

[0034] The lower part of the arch member clamp 120 is provided with a reinforcing rib 122 to enhance structural strength. The reinforcing rib 122 is located on the side of the arch member clamp 120 opposite to the insertion port 140 and is triangular in shape. The two sides of the reinforcing rib 122 are parallel to the sides of the arch member clamp 120, which increases the arch member clamp 120's resistance to deformation. A fourth mounting through hole 123 is provided at the reinforcing rib 122, and the positions of the fourth mounting through holes 123 on the two arch member clamps 120 correspond. Bolts, rivets, and other connectors are inserted through the fourth mounting through holes 123 to connect the two arch member clamps 120. Combined with the stress dispersion provided by the reinforcing rib 122, this effectively improves the connection strength between the column head connector 100 and the arch member 300.

[0035] Preferably, the column head connector 100 has a centrally symmetrical structure with the vertical axis of the column connecting plate 110 as the axis of symmetry. This structure possesses excellent mechanical properties, facilitating alignment and installation, and ensuring uniform stress distribution after installation. Furthermore, the column head connector 100 is a one-piece stamped metal part, which reduces weak points in the structural splicing, ensuring overall strength and stability. The column head connector 100 is made of high-strength, corrosion-resistant steel, offering advantages such as high strength and corrosion resistance, thus guaranteeing a certain service life.

[0036] It is evident that the column head connector 100 can achieve a stable connection between the column 200, the arch rod 300 and the water tank 400, and has many advantages such as flexible installation, strong versatility, and stable and safe use.

[0037] Example 2

[0038] Based on the above-described embodiment one, this utility model also provides a canopy frame, including the aforementioned canopy frame column head connector 100, uprights 200, arch rods 300, and water troughs 400. The column head connector 100 is fixedly mounted on the upper end of the upright 200 through a first mounting through hole 111, and two column head connectors 100 are arranged opposite each other on any upright 200. The end of the arch rod 300 is inserted into a corresponding socket 140, and a bolt is installed in the second mounting through hole 121 to secure the end of the arch rod 300 against the socket 140. The end of the water trough 400 is mounted above the upright 200 and is fixedly connected to the ear plate 130 on the column head connector 100.

[0039] Thanks to the multiple functions of the column head connector, the scaffolding is relatively easy to assemble and efficient. Once assembled, the structure is stable and requires relatively little maintenance.
