[0023] The present invention will now be described in detail with reference to the accompanying drawings and embodiments.

[0024] As shown in the figure, a connector for agricultural greenhouses includes two outwardly opening connecting covers 1 fixed together. The distance between the two connecting covers 1 is adjustable. A support sleeve 7 is fixed inside each connecting cover 1. A limit pin 9 is screwed to one side of each connecting cover 1. A through hole 701 is provided on the support sleeve 7 corresponding to the limit pin 9. In this embodiment, during use, the two adjustable connecting covers 1 are sleeved on the near ends of two connecting rods, and the connecting rods are sleeved with the corresponding support sleeves 7. Then, the limit pins 9 are used to strengthen the stability between the connecting rods and the corresponding support sleeves 7. Finally, the two connecting covers 1 are fixed together. Of course, to further ensure the connection stability between the connecting rods and the support sleeves 7, positioning holes can be opened on the connecting rods so that the end of the limit pin 9 can be inserted into the positioning hole.

[0025] The two connecting covers 1 are fixed together by wing bolts 5.

[0026] A first fixing block 2 is fixedly connected to both the upper and lower sides of one of the connecting covers 1, and a second fixing block 3 is fixedly connected to both the upper and lower sides of the other connecting cover 1 at the corresponding positions of the first fixing block 2. Mounting holes are provided on both the first fixing block 2 and the second fixing block 3, and a retaining ring 4 with internal threads is welded to one side of the second fixing block 3 at the corresponding mounting hole. The screw of the wing bolt 5 passes through the mounting holes of the first fixing block 2 and the second fixing block 3 in sequence and is screwed together with the retaining ring 4. In this embodiment, the retaining ring 4 is provided on one side of the second fixing block 3 to provide a connection position for fixing the wing bolt 5, eliminating the need for thicker first fixing blocks 2 and second fixing blocks 3, thus avoiding the situation where the connection is not stable enough with the wing bolt 5.

[0027] A connecting ring 6 with internal threads is fixedly attached to the side wall of each connecting cover 1 away from the opening. The support sleeve 7 includes a support ring 702 with a sealed rear end and a connecting post 703 fixed to the outer side of the rear end of the support ring 702. The connecting post 703 has external threads. The support sleeve 7 is fixed in the connecting cover 1 by the screw connection between the connecting post 703 and the connecting ring 6. In this embodiment, the support sleeve 7 is detachably installed in the connecting cover 1, which facilitates the replacement of support sleeves 7 of different specifications, that is, the replacement of support rings 702 of different shapes (circular or square) and sizes. This makes it suitable for connecting rods of various shapes and sizes, such as hollow round tubes, solid round steel, hollow square tubes, and solid square steel. In this embodiment, the support sleeve 7 is a one-piece molded structure.

[0028] The support ring 702 has a circular or square frame structure. The circular support ring 702 is suitable for round steel and round pipes, while the square support ring 702 is suitable for square pipes and square steel.

[0029] A through hole 701 is provided on one side of the support ring 702, and a limiting platform 8 is fixedly connected to one side of the connecting cover 1. A threaded hole 801 is provided on the limiting platform 8, which penetrates the limiting platform 8 and the corresponding side wall of the connecting cover 1. The through hole 701 and the threaded hole 801 are aligned. The limiting pin 9 is screwed into the threaded hole 801 and can pass through the through hole 701. When a hollow round or square tube is sleeved on the outside of the support ring 702, the limiting pin 9 can be pressed against the outside of the steel tube. When the steel tube is a solid round or square steel, or the steel tube is a hollow structure and its size is suitable for insertion into the support ring 702, the end of the steel tube is inserted into the support ring 702. At this time, the end of the limiting pin 9 passes through the through hole 701 and presses against the steel tube.

[0030] In this embodiment, the connecting cover 1 is a square structure with a hollow interior and an opening at one end.

[0031] In this embodiment, the connecting cover 1, the limiting platform 8, the connecting ring 6, and the corresponding first fixing block 2 or second fixing block 3 are integrally formed structures.

[0032] The working process of this embodiment is as follows:

[0033] When constructing agricultural greenhouses, this connector is used to connect two adjacent aligned connecting rods. During installation, the two connecting covers 1 are respectively sleeved onto the corresponding connecting rods via support sleeves 7. When sleeved, if the connecting rod is a hollow round or square tube, the connecting rod is sleeved on the outside of the support ring 702, and the limiting pin 9 is pressed against the steel tube. If the connecting rod is a solid round or square steel, or if the connecting rod is a hollow structure and its size is suitable for insertion into the support ring 702, the end of the connecting rod is inserted into the support ring 702 of the corresponding structure. At this time, the end of the limiting pin 9 passes through the through hole 701 and presses against the connecting rod. Then, the two connecting covers 1 are fixed together by the wing bolts 5.

[0034] In this embodiment, the corresponding support sleeve 7 can be replaced according to the actual structure of the connecting rod to ensure that the connecting rod can be sleeved on the outside or inside of the support ring 702.

[0035] The above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
