Description

TECHNICAL FIELD

[0001] The utility model relates to steel pipe connecting technical field, concretely is a steel pipe connecting structure. BACKGROUND

[0002] In modern agricultural production, the greenhouse as an important agricultural facility is widely used in the planting of vegetables, fruits, flowers and other crops to provide suitable growth environment and extend the production cycle. The core component of the greenhouse structure is the steel pipe frame, which not only needs to bear its own structural weight and crop load, but also needs to resist external environmental factors such as wind, snow and other natural conditions. The steel pipe used in the greenhouse is usually made of high-strength, corrosion-resistant material to ensure the stability and durability of the entire structure. The specifications and shapes of the steel pipe need to be accurately manufactured according to the size and shape of the greenhouse design to ensure the sealing and mechanical strength of the overall structure.

[0003] Traditionally, the connection of the greenhouse steel pipe mainly adopts welding or binding. Although these two methods are common, they have obvious inconvenience and limitations in practical application. Although welding can provide strong connection strength, any adjustment or disassembly work becomes extremely difficult once the welding is completed. When the greenhouse needs to be rearranged or expanded, the irreversibility of the welding points will result in the need to completely disassemble and rebuild the entire structure, which not only increases the labor and time cost, but also may affect the overall structural stability of the greenhouse. Although the binding method is more flexible, the operation process is complicated and time-consuming, especially in large-scale agricultural production, a large amount of binding work will significantly increase the workload of construction and maintenance.

[0032] Embodiment

[0033] Please refer to Figures 1-5 As shown in the utility model provides a kind of steel pipe connecting structure technical scheme: a kind of steel pipe connecting structure, including two staggered steel pipes 1, the outer side of steel pipe 1 is equipped with connecting frame 2, the inner side of connecting frame 2 is equipped with two through holes 3 for accommodating steel pipe 1, the inner side of through hole 3 is equipped with clamping assembly 4, the end of clamping assembly 4 is equipped with telescopic assembly 5 for controlling clamping assembly 4;

[0034] The clamping assembly 4 comprises a limiting plate 401, a surrounding part 402, and a first rubber layer 403. The limiting plate 401 is slidably arranged in the inner side of the through hole 3. The limiting plate 401 and the upper end of the through hole 3 are both designed with the surrounding part 402. The bottom of the limiting plate 401 is connected with the telescopic assembly 5. The first rubber layer 403 is arranged on the surface of the surrounding part 402 of the through hole 3 and the limiting plate 401. During installation, one of the through holes 3 of the connecting frame 2 is sleeved on one steel pipe 1. Then, the other steel pipe 1 is inserted into the other through hole 3 of the connecting frame 2. Next, the connecting frame 2 and the second steel pipe 1 are moved to the predetermined connection position. Then, the limiting plate 401 in each through hole 3 is lifted by operating the telescopic assembly 5. When the telescopic assembly 5 reaches the predetermined position, the two first rubber layers 403 will lock the two steel pipes 1 which are arranged in the longitudinal and transverse directions, thereby completing the connection of the two steel pipes 1.

[0035] The telescopic assembly 5 comprises a plurality of sliding holes 501, a movable cavity 503, a rotating rod 505, and a loosening prevention plate 506. The sliding hole 501 is arranged in the connecting frame 2 and located at the lower end of each through hole 3. The sliding rod 502 is slidably connected in the sliding hole 501. The end of the sliding rod 502 is connected with the limiting plate 401. The movable cavity 503 is arranged in the connecting frame 2. The push plate 504 is arranged in the movable cavity 503. The surface of the push plate 504 is connected with the sliding rod 502. The rotating rod 505 is threadedly connected with the bottom of the connecting frame 2. The top of the rotating rod 505 is rotatably connected with the push plate 504. The loosening prevention plate 506 is arranged on the side of the rotating rod 505. When locking the position of the two steel pipes 1, the operator needs to rotate the rotating rod 505. During the rotation, the rotating rod 505 drives the push plate 504 to move upward or downward. If the push plate 504 moves upward, the sliding rod 502 will simultaneously lift the limiting plates 401 in the two through holes 3. When the two steel pipes 1 are completely clamped, the loosening prevention plate 506 will provide a fastening effect and provide higher friction to avoid loosening.

[0036] In the specific implementation process, corresponding sliding grooves can be arranged on the limiting plate 401, the through hole 3, the movable cavity 503, and the push plate 504, so as to further improve the stability and effect of the operation.

[0037] The loosening prevention plate 506 comprises a supporting plate 5061 and a second rubber layer 5062. The supporting plate 5061 is arranged on the side of the rotating rod 505. The second rubber layer 5062 is arranged on the upper end surface of the supporting plate 5061. When the loosening prevention plate 506 contacts with the bottom of the connecting frame 2, the second rubber layer 5062 starts to compress with the further rotation of the rotating rod 505. With the further tightening of the rotating rod 505, the second rubber layer 5062 is compressed and deformed to fill the small gap between the plate surface of the supporting plate 5061 and the bottom of the connecting frame 2, and to keep the position of the rotating rod 505 stable in the normal state, thereby preventing self-rotation or slipping.

[0038] The end of the sliding hole 501 is designed with an enlarged portion 5011, and the connecting portion of the sliding rod 502 with the limiting plate 401 is provided with a pressure bearing portion 6; the pressure bearing portion 6 is designed to be widened, so that the connecting portion can bear greater stress, the local stress concentration is reduced, and the damage risk of the connecting portion is reduced, and the design of the enlarged portion 5011 can provide space for the accommodation of the sliding rod 502, so that the bottom of the limiting plate 401 can be fully attached to the inner wall of the hole body of the through hole 3 after the sliding rod 502 is fully retracted into the sliding hole 501.

[0039] The material of the first rubber layer 403 and the second rubber layer 5062 is ethylene-propylene rubber; this design can make the steel pipe connecting structure more suitable for the environment of sunlight direct radiation of the greenhouse. In addition, the ethylene-propylene rubber also has good elasticity and wear resistance, can bear multiple disassembly and installation. At the same time, its cost is relatively low, and is suitable for large-scale use.

[0040] The working principle of the utility model is as follows:

[0041] In use, the utility model of a steel pipe connecting structure first sets one through hole 3 in the connecting frame 2 on one steel pipe 1, and then passes the other steel pipe 1 through the other through hole 3 of the connecting frame 2. Then, the connecting frame 2 and the second steel pipe 1 are moved to the predetermined connecting position. By operating the telescopic assembly 5, the limiting plate 401 in each through hole 3 is lifted, and when the telescopic assembly 5 reaches the predetermined position, the two first rubber layers 403 will lock the two longitudinal and transverse steel pipes 1, thereby completing the connection of the two steel pipes 1. In the locking position, the operator needs to rotate the rotating rod 505, and in the rotating process, the rotating rod 505 drives the push plate 504 to move upward or downward, so that the sliding rod 502 synchronously lifts the limiting plate 401 in the two through holes 3. When the steel pipe 1 is completely clamped, the anti-loose plate 506 will play a fastening role, providing higher friction, to avoid loosening. In this way, through the accurate control of the telescopic assembly 5 and the safety protection of the anti-loose plate 506, the structure not only realizes the rapid connection of the steel pipe, but also ensures the stability and long-term reliability of the connection.

[0042] The basic principle, main features and advantages of the utility model are shown and described above. Those skilled in the art should understand that the utility model is not limited by the above examples, and the above examples and descriptions in the specification are only preferred examples of the utility model and are not intended to limit the utility model. Without departing from the spirit and scope of the utility model, the utility model can also have various changes and improvements, and these changes and improvements all fall within the scope of the claimed utility model. The scope of protection of the utility model is defined by the appended claims and their equivalents.
