A greenhouse steel structure connecting assembly

Abstract

This utility model relates to the technical field of greenhouse steel structure, and in particular to a connecting component for greenhouse steel structure, including a shell. A connecting block is fixedly connected to one side of the lower surface of the shell, and a fixed shaft is fixedly connected to one side of the connecting block. During use, a third bolt drives the second fixed block to move on the surface of the fourth sliding groove inside the sleeve until the second fixed block is tightly abutted against the diagonal brace. Then, the second fastening nut is rotated to fix the third bolt a second time. At the same time, the first bolt will not rotate when the nut of the first bolt is rotated due to the shape limitation of the square sliding block at the end. Moreover, the first sliding grooves on both sides of the shell and the second sliding grooves on both sides of the diagonal brace cooperate with the first bolt, so that the angle of the diagonal brace can be flexibly adjusted to meet the angle requirements of different diagonal connections. Finally, a stable and adjustable connection between the horizontal bar, the vertical column and the diagonal brace is achieved, which greatly improves the cooling efficiency of the lathe.

Description

Technical Field

[0001] This utility model relates to the technical field of greenhouse steel structure, and in particular to a connection component for greenhouse steel structure. Background Technology

[0002] Greenhouses, as core facilities for large-scale modern agricultural planting and ensuring year-round crop production, require steel structures with excellent stability to withstand natural loads such as wind and snow, while also adapting to the planting span requirements and efficient construction scenarios of different regions. With agricultural production placing increasing emphasis on facility flexibility, assembly efficiency, and total life-cycle costs, there is an urgent need for steel structure connection components that can be quickly assembled, angle-adjustable, weather-resistant, and easily reusable, adaptable to various pipe materials such as round and square tubes, facilitating convenient construction of greenhouses in different terrains and planting modes. Therefore, a greenhouse steel structure connection component is particularly needed. However, existing greenhouse steel structure connections often rely on on-site welding or single-specification fixed connectors. Fixed connectors have fixed angles and specifications, failing to flexibly adapt to greenhouse designs with different spans and bracing angles, resulting in poor versatility. Furthermore, most traditional connection methods are non-removable rigid connections, making them difficult to reuse during greenhouse renovations or structural adjustments, increasing long-term investment costs for agricultural facilities and affecting the efficiency of greenhouse steel structure utilization. To solve the above problems, after searching, the patent with announcement number CN209482486U disclosed a steel structure greenhouse beam-column connection plate. The article states that "this utility model provides a steel structure greenhouse beam-column connection plate with the following beneficial effects: (1) The connection plate of this utility model is a detachable structure and is composed of side plates and horizontal plates. When in use, by fixing the horizontal plate between the two side plates, it can be easily spliced ​​into a connection plate. When not in use, it can be easily disassembled, reducing the space occupied and making it convenient to store." This device realizes the functions of detachable splicing and adjusting the fixed spacing according to the column plate size. However, it lacks an adjustable connection design for the angle of the inclined support component, which cannot flexibly adapt to the changing needs of the angle of the inclined support under different spans of the greenhouse, and is difficult to meet the scenario where the angle of the inclined component needs to be adjusted due to differences in terrain or load. Moreover, its connection structure is mainly for the cooperation of "plate" column plates with side plates and horizontal plates. It has poor adaptability to the commonly used round pipe and other rod-type steel structures in greenhouses and cannot directly realize the fast and stable connection of round pipe components. In light of this, in-depth research into the aforementioned issues led to the creation of this case. Utility Model Content

[0003] The purpose of this utility model is to provide a connecting component for greenhouse steel structures to solve the problems mentioned in the background art regarding existing greenhouse steel structure connections. In use, traditional greenhouse steel structure connections mostly rely on on-site welding or fixed connectors of a single specification. Fixed connectors have fixed angles and specifications, which cannot flexibly adapt to greenhouse designs with different spans and different bracing angles, resulting in poor versatility. In addition, most traditional connection methods are non-removable rigid connections, which are difficult to reuse when the greenhouse is renovated or the structure is adjusted, increasing the long-term investment cost of agricultural facilities and affecting the efficiency of greenhouse steel structure use.

Detailed Implementation

[0014] 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 of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0015] Please see Figures 1-5This utility model provides a technical solution: a steel structure connection component for a greenhouse, including a shell 1, a connecting block 2 fixedly connected to one side of the lower surface of the shell 1, a fixed shaft 3 fixedly connected to one side of the connecting block 2, a bearing connected to a diagonal rod 5 on one side of the surface of the fixed shaft 3, a first bolt 7 movably sleeved on one side of the surface of the diagonal rod 5, a sliding block 8 fixedly connected to one end of the first bolt 7, a third sliding groove 9 formed on the inner surface of the shell 1, a second bolt 10 threadedly connected to one side of the surface of the shell 1, a first fastening nut 11 threadedly connected to one side of the surface of the second bolt 10, a first fixed block 12 slidably connected to the surface of the third sliding groove 9, and a first fixed block 12 slidably connected to the surface of the diagonal rod 5. A sleeve 13 is fixedly connected to the side. A fourth sliding groove 14 is formed on the inner surface of the sleeve 13. A third bolt 15 is threaded to one side of the surface of the sleeve 13. A second fastening nut 16 is threaded to one side of the surface of the third bolt 15. A second fixing block 17 is slidably connected to the surface of the fourth sliding groove 14. In use, the vertical column is first installed and fixed: the column is inserted into the inner area below the outer casing 1. Then, the second bolt 10 in the vertical direction on the surface of the outer casing 1 is rotated. The second bolt 10 pushes the first fixing block 12 to slide in the third sliding groove 9 until the first fixing block 12 is tightly fitted with the column. Then, the first fastening nut 11 is tightened. Nut 11 is tightened to lock the second bolt 10, ensuring the column is securely clamped. Then, the horizontal crossbar is installed: rotate the second bolt 10 horizontally on the surface of the outer casing 1, causing the first fixing block 12 to retract within the third sliding groove 9. Insert the horizontal crossbar into the inner side of the horizontal section of the outer casing 1. Then, rotate the second bolt 10 in the opposite direction to ensure the first fixing block 12 is tightly against the horizontal crossbar. Tighten the first fastening nut 11 to complete the crossbar fixing. Next, adjust the angle and fixation of the diagonal brace: loosen the nut of the first bolt 7. Since the diagonal brace 5 is connected to the bearing of the connecting block 2 via the fixed shaft 3, the diagonal brace 5 can rotate around the fixed shaft 3. At this time, the first bolt 7 will be in the first sliding groove of the outer casing 1. The first bolt 7 slides within the second sliding groove 6 of the diagonal bar 4 and the second sliding groove 6 of the diagonal bar 5 to adapt to the rotation angle of the diagonal bar 5. After the angle is adjusted to the appropriate position, the nut of the first bolt 7 is tightened. The rotation of the first bolt 7 is restricted by the cooperation between the sliding block 8 and the outer shell 1, thereby fixing the angle of the diagonal bar 5. Finally, the diagonal brace is installed: the diagonal brace is inserted into the two sets of sleeves 13, and the third bolt 15 is rotated. The third bolt 15 pushes the second fixing block 17 to slide within the fourth sliding groove 14, so that the second fixing block 17 and the diagonal brace fit tightly together. Then, the second fastening nut 16 is tightened to lock the third bolt 15, completing the fixing of the diagonal brace. Finally, a stable connection and adjustable angle diagonal support are achieved between the column, the crossbar and the diagonal brace.

[0016] Furthermore, the outer casing 1 has a first sliding groove 4 on both sides, and the inclined rod 5 has a second sliding groove 6 on both sides. During use, the first sliding groove 4 provides horizontal sliding space for the first bolt 7, and the second sliding groove 6 provides guiding space for the first bolt 7 to rotate with the inclined rod 5. The two work together to ensure that when the inclined rod 5 rotates around the fixed axis 3 to adjust the angle, the first bolt 7 can smoothly follow the displacement, ensuring the smoothness of the angle adjustment.

[0017] Furthermore, the sliding block 8 is slidably connected to the outer shell 1, and the first bolt 7 is slidably connected to the outer shell 1. Through the setting of the sliding block 8 and the outer shell 1, the sliding block 8 can slide inside the outer shell 1. At the same time, the shape of the sliding block 8 restricts the rotation of the first bolt 7, so that the first bolt 7 can only slide along the groove, avoiding the bolt itself from rotating when tightening the nut, and improving the convenience of angle fixing. Through the setting of the first bolt 7 and the outer shell 1, the first bolt 7 serves as both a fastener for fixing the angle of the inclined rod 5 and a guide for adjusting the angle of the inclined rod 5 through sliding cooperation with the outer shell 1, realizing "one bolt for multiple uses" and simplifying the structure.

[0018] Furthermore, the first bolt 7 is slidably connected to the diagonal rod 5, and the second bolt 10 is fitted to the first fixing block 12. Through the setting of the first bolt 7 and the diagonal rod 5, the first bolt 7 slides in the second sliding groove 6 of the diagonal rod 5, providing displacement margin for the rotation of the diagonal rod 5, ensuring that the bolt does not restrict the rotation range of the diagonal rod 5 during angle adjustment. Through the setting of the second bolt 10 and the first fixing block 12, the second bolt 10 can directly push the first fixing block 12 to move in the third sliding groove 9. Utilizing the stability of the threaded transmission, the clamping force of the first fixing block 12 on the crossbar or column is more uniform and stable, improving the reliability of the connection.

[0019] Furthermore, the third bolt 15 is attached to the second fixing block 17. With the setting of the third bolt 15 and the second fixing block 17, when the third bolt 15 rotates, it can push the second fixing block 17 to slide in the fourth sliding groove 14, thereby clamping the diagonal brace in the sleeve 13. The preload of the bolt is used to achieve the rapid fixing of the diagonal brace, and the clamping force can be precisely adjusted by turning the bolt to adapt to diagonal brace pipes of different diameters.

[0020] Furthermore, two sets of sleeves 13 are provided. With the two sets of sleeves 13, the two sets of sleeves 13 can simultaneously clamp and fix the two sets of diagonal braces at different angles, thereby improving the stability and bending resistance of the diagonal brace connection.

[0021] Furthermore, the first sliding groove 4 is slidably connected to the first bolt 7, and the second sliding groove 6 is slidably connected to the first bolt 7. Through the setting of the first sliding groove 4 and the first bolt 7, the first sliding groove 4 provides horizontal limiting and guiding for the first bolt 7, ensuring that the first bolt 7 slides along a predetermined trajectory when the diagonal bar 5 rotates, avoiding bolt offset that would cause angle adjustment to become stuck. Through the setting of the second sliding groove 6 and the first bolt 7, the second sliding groove 6 provides arc-shaped guiding for the first bolt 7 as it rotates with the diagonal bar 5, enabling the first bolt 7 to adapt to the rotation trajectory of the diagonal bar 5, ensuring that the diagonal bar 5 can be smoothly adjusted at the angle, and meeting the diagonal support requirements of different greenhouse spans.

[0022] Working principle: During use, the horizontal crossbar is first fixed by loosening the first fastening nut 11 on the surface of the four sets of second bolts 10 on one side of the horizontal section of the outer shell 1. This releases the first fastening nut 11 from the fixation of the second bolts 10. Then, the second bolts 10 are loosened. At this time, the rotation of the second bolts 10 will cause the first fixing block 12 to move on the surface of the third sliding groove 9 on the inner side of the outer shell 1, thus making enough space for the horizontal crossbar to be inserted. After the horizontal crossbar is inserted, the second bolts 10 are rotated in the opposite direction. The second bolts 10 will push the first fixing block 12 to move. When the first fixing block 12 is tightly pressed against the surface of the crossbar, the first fastening nut 11 is rotated to fix the second bolts 10 a second time, preventing loosening during subsequent use. Next, the vertical column is fixed. One end of the column is inserted into the inner surface of the lower end of the outer casing 1. The first fastening nuts 11 on the surface of the two sets of second bolts 10 on one side of the vertical section of the outer casing 1 are loosened. Then, the second bolts 10 are loosened. The rotation of the second bolts 10 causes the first fixing block 12 to move within the third sliding groove 9. After the column is inserted, the second bolts 10 are rotated to make the first fixing block 12 tightly abut against the column. Then, the first fastening nuts 11 are rotated to fix the second bolts 10 a second time. Finally, the diagonal brace is installed and its angle is adjusted: the nuts of the first bolts 7 on the vertical section of the outer casing 1 are loosened. Since the diagonal rod 5 forms a rotating structure with the horizontal section of the outer casing 1 through the fixed shaft 3, the diagonal rod 5 can rotate around the fixed shaft 3 at a certain angle. The diagonal brace is passed through the two sets of sleeves 13. First, the second fastening nuts 16 on the surface of the third bolt 15 are loosened. After the diagonal brace passes through the sleeves 13, the third bolt 15 is rotated. The third bolt 15 causes the second fixing block 17 to move within the fourth sliding groove 14 on the inner side of the sleeve 13 until the second fixing block 17 tightly abuts against the diagonal brace. Then, rotate the second fastening nut 16 to fix the third bolt 15 a second time. At the same time, due to the shape limitation of the square sliding block 8 at the end of the first bolt 7, it will not rotate when the nut of the first bolt 7 is rotated. Moreover, the first sliding groove 4 on both sides of the outer shell 1 and the second sliding groove 6 on both sides of the diagonal rod 5 cooperate with the first bolt 7, so that the diagonal rod 5 can flexibly adjust the angle to meet the angle requirements of different diagonal connections. Finally, a stable and adjustable connection of the horizontal bar, vertical column and diagonal brace is achieved, which greatly improves the utilization efficiency of the greenhouse steel structure.
