Description

Technical Field

[0001] This utility model belongs to the field of greenhouse frame technology, and in particular relates to a steel pipe structure for greenhouse frames with adjustable length. Background Technology

[0002] An adjustable-length steel pipe frame structure for greenhouses is typically designed to provide flexibility and adaptability to meet the needs of different greenhouses or sheds. A key feature of this structure is its ability to adjust the length of the steel pipes, allowing for easy adjustments to the size, shape, and height of the greenhouse to suit various usage requirements.

[0003] According to a public disclosure (Publication No.: CN 213718976 U), an adjustable-length steel pipe for greenhouse frame includes an outer rod and a rotating cylinder. An inner rod is slidably connected to the inner side of the outer rod, and a limit strip is fixedly connected to the outer side of the rotating cylinder. The limit strip is evenly arranged on the outer side of the rotating cylinder. In this utility model, the inner rod, outer rod, connecting ring, rotating cylinder and other components are provided.

[0004] In the aforementioned application, the cooperation between components such as the outer rod and the rotating cylinder makes it difficult to easily adjust the length of the frame, which reduces the ease of use and makes it impossible to quickly adjust the length. This needs to be improved. Utility Model Content

[0005] The purpose of this utility model is to provide an adjustable-length steel pipe structure for greenhouse frames. Through the interplay of components such as racks, gears, and round rods within the adjustable assembly, the length of the frame can be easily adjusted by the user via a handle, without the need for complex tools or procedures, thus enhancing ease of use. This is especially true when adjusting the height or length of the greenhouse, which can be done quickly. The locking groove design of the limiting rod effectively locks the position of the steel pipe, preventing accidental displacement during use, thus solving existing problems.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution:

[0007] This utility model relates to an adjustable-length steel pipe structure for greenhouse frames, comprising a frame tube, with steel pipes slidably connected to the inner wall of the frame tube. An adjustment component is provided on the inner wall of the frame tube, the adjustment component including a rectangular groove formed on the inner wall of the frame tube. A rack is fixedly connected to the side of the steel pipe, and a short rod is fixedly connected to the inner wall of the rectangular groove. One end of the short rod is rotatably connected to a gear, and a round rod is fixedly connected to the side of the gear. A round groove is formed on the side of the frame tube, and the end of the round rod away from the gear passes through the inner wall of the round groove. A handle is fixedly connected to one end of the round rod.

[0008] Furthermore, the gear and rack mesh with each other, and the rectangular groove is located on the displacement trajectory of the rack. This design is beneficial for driving the rack to move when the gear rotates.

[0023] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those skilled in the art without creative effort are within the protection scope of the present utility model.

[0024] Please see Figures 1-4 As shown, this utility model is a steel pipe structure for an adjustable-length greenhouse frame, including a frame pipe 1, a steel pipe 2 slidably connected to the inner wall of the frame pipe 1, and an adjustment component 3 provided on the inner wall of the frame pipe 1. The adjustment component 3 includes a rectangular groove 31, which is opened on the inner wall of the frame pipe 1. A rack 32 is fixedly connected to the side of the steel pipe 2. A short rod 33 is fixedly connected to the inner wall of the rectangular groove 31. A gear 34 is rotatably connected to one end of the short rod 33. A round rod 35 is fixedly connected to the side of the gear 34. A round groove is opened on the side of the frame pipe 1. The end of the round rod 35 away from the gear 34 passes through the inner wall of the round groove. A handle 36 is fixedly connected to one end of the round rod 35.

[0025] Furthermore, the gear 34 and the rack 32 mesh with each other, and the rectangular groove 31 is located on the displacement trajectory of the rack 32. This design is beneficial to drive the rack 32 to move when the gear 34 rotates.

[0026] Furthermore, a rectangular rod 310 is fixedly connected to the side of the skeleton tube 1. The side of the rectangular rod 310 is provided with a slot 311. The design of the slot 311 is beneficial to restrict the position of the steel tube 2.

[0027] Furthermore, a handle 37 is fixedly connected to the side of the steel pipe 2, and a connecting rod 38 is rotatably connected to the side of the handle 37. The design of the handle 37 is conducive to moving the steel pipe 2.

[0028] Furthermore, a limiting rod 39 is fixedly connected to one end of the connecting rod 38, and the slot 311 is located on the displacement trajectory of the limiting rod 39. The design of the limiting rod 39 is beneficial to temporarily lock the position of the steel pipe 2.

[0029] Furthermore, several slots 311 are provided and are arranged in a linear array on the side of the rectangular rod 310. The slots 311 are located on the side of the steel pipe 2. With multiple slots 311, the steel pipe 2 can be locked in multiple positions.

[0030] A specific application of this embodiment is as follows: the frame tube 1 is used on the greenhouse frame. A movable steel pipe 2 is installed on the inner wall of the frame tube 1. In its initial state, the steel pipe 2 passes through the inner wall of the frame tube 1 and is slidably connected to the frame tube 1. When sliding is required, the handle 36 is gripped and rotated clockwise. The rotation of the handle 36 will drive the round rod 35 to rotate, which in turn will drive the gear 34 to rotate clockwise. The gear 34 and the rack 32 mesh with each other. When the gear 34 rotates clockwise, it will drive the rack 32 to move upward, causing the rack 32 to move upward. Sliding along the inner wall of the rectangular groove 31 allows the steel pipe 2 to move upwards, thus stretching it out from the skeleton pipe 1 and increasing the overall length of the skeleton pipe 1. When it is necessary to shorten the overall length of the skeleton pipe 1, the handle 36 is reversed. Reversing the handle 36 will cause the round rod 35 and gear 34 to reverse, which in turn will cause the rack 32 to move downwards. The downward movement of the rack 32 will cause the steel pipe 2 to move downwards, causing it to retract into the skeleton pipe 1, thereby shortening the length of the skeleton pipe 1. After adjustment, the steel pipe 2 will be able to move upwards. When the position of pipe 2 is adjusted, the connecting rod 38 and the limiting rod 39 are rotated towards the side closer to the slot 311, locking the limiting rod 39 into the slot 311 and temporarily locking the position of the steel pipe 2. The adjustable steel pipe 2 allows the greenhouse length to be changed according to actual needs, adapting to different environments or greenhouse sizes. This flexibility enables the greenhouse structure to be adjusted according to the season or planting requirements. Through the operation of the handle 36, the user can easily adjust the length of the frame without complicated tools or procedures, enhancing ease of use. Especially when adjusting the height or length of the greenhouse, it can be done quickly. The meshing design of the gear 34 and rack 32 ensures smooth sliding of the steel pipe 2, reducing possible vibration or instability during adjustment. Simultaneously, the slot 311 design of the limiting rod 39 effectively locks the position of the steel pipe 2, preventing accidental displacement during use.
