Description

Technical Field

[0001] This utility model mainly relates to the field of steel structure technology, and specifically to a steel structure connector. Background Technology

[0002] Nowadays, in many building construction processes, steel structures are used for reinforcement to improve the safety of buildings. A steel structure refers to a structure made of steel materials. The structure is mainly composed of steel beams, steel columns, steel trusses and other components made of steel sections and steel plates. In the process of using steel structures, individual steel structures are used to build the structure for easy installation, and then different steel structures are fixed together to form a whole steel structure.

[0003] Nowadays, most steel structure connections are made using welded, bolted, or riveted connections. These connection methods can lead to difficulties in disassembling the steel structure after use, making it difficult to maintain or replace it later. In addition, some steel structures are prone to distance deviations during the connection process, which can affect the stability of the connection between steel structures. Utility Model Content

[0025] This application provides a steel structure connector, as shown in the schematic diagram below. Figure 1-4 As shown. Steel structure connector; including steel pipe 10 and connecting pipe fitting 20, both ends of the connecting pipe fitting 20 are provided with slots adapted to the steel pipe 10.

[0026] Both ends of the connecting pipe fitting 20 are provided with multiple connecting plugs 30. Each connecting plug 30 includes a fixing block 31 connected to the connecting pipe fitting 20, a column cavity set in the fixing block 31, a positioning shaft 33 that passes through the column cavity and extends to the slot, a top button 32 installed on the top of the positioning shaft 33, a fixing plate 35 located in the column cavity and connected to the positioning shaft 33, and a spring 34 located on the top of the fixing plate 35 and sleeved on the positioning shaft 33. The steel pipe 10 is provided with multiple positioning slots 11 that are adapted to the positioning shaft 33.

[0027] For details, please refer to the appendix. Figure 1 Multiple connecting plugs 30 are distributed in a circular pattern at both ends of the connecting pipe fitting 20.

[0028] It should be noted that, in this embodiment, the connection between the connecting pipe 20 and the steel pipe 10 is made more stable by using multiple equally spaced connecting plugs 30, thus preventing shaking.

[0029] For details, please refer to the appendix. Figure 3 A partition plate 23 is provided in the middle of the connecting pipe fitting 20.

[0030] It should be noted that in this embodiment, the distance that the steel pipe 10 is inserted into the connecting pipe fitting 20 can be limited by the partition plate 23, so that when the steel pipe 10 contacts the partition plate 23, the positions of the positioning slot 11 and the positioning shaft 33 are at the same cross section.

[0031] For details, please refer to the appendix. Figure 2One end of the steel pipe 10 is provided with an annular groove 12, and the center of both sides of the partition plate 23 is provided with an annular block 21 that matches the annular groove 12.

[0032] It should be noted that in this embodiment, when the steel pipe 10 and the connecting fitting 20 are connected, the annular block 21 will be inserted into the annular groove 12, thereby increasing the connection area between the steel pipe 10 and the connecting fitting 20 and increasing stability.

[0033] For details, please refer to the appendix. Figure 3 The inner side of the annular block 21 has multiple arc-shaped blocks 22 distributed in a circular pattern, and the inner wall of the annular groove 12 is provided with an arc-shaped notch 13 that matches the arc-shaped blocks 22.

[0034] It should be noted that in this embodiment, when the annular block 21 is inserted into the annular groove 12, the arc-shaped block 22 and the arc-shaped notch 13 need to be inserted in alignment so that the positions of the positioning slot 11 and the positioning shaft 33 are precisely aligned, which facilitates the docking of the steel structure.

[0035] For details, please refer to the appendix. Figure 4 The top of the fixing block 31 is provided with a limiting cylinder 36, the inner wall of the top of the limiting cylinder 36 is provided with an internal thread, and the outer wall of the top button 32 is provided with an external thread.

[0036] It should be noted that in this embodiment, after the positioning shaft 33 is partially inserted into the positioning slot 11, the positioning shaft 33 can be turned to make it continue to descend, thereby securing it into the positioning slot 11. At the same time, the top button 32 is fixed to the limiting cylinder 36 to prevent shaking from causing the positioning shaft 33 to loosen from the positioning slot 11, thus increasing stability.

[0037] For details, please refer to the appendix. Figure 4 The top of the top button 32 has a square groove.

[0038] It should be noted that, in this embodiment, a square screwdriver can be inserted into the square groove of the top button 32 to lower the positioning shaft 33, thereby causing the top button 32 to rotate into the limiting cylinder 36 for fixing.

[0039] It should also be noted that the two ends of the steel pipe 10 can be set to the same shape, which facilitates the assembly of multiple steel pipes 10.

[0040] The specific operation method of this utility model is as follows:

[0041] When it is necessary to connect two steel pipes 10, insert one end of the two steel pipes 10 into the interior of the connecting fitting 20. At this time, pull the top button 32 upward to prevent the positioning shaft 33 from blocking the insertion of the steel pipe 10. At the same time, align and insert the arc-shaped block 22 and the arc-shaped notch 13 so that the annular block 21 is inserted into the annular groove 12.

[0042] When the steel pipe 10 contacts the partition plate 23, the positioning slot 11 and the positioning shaft 33 are at the same cross section. Then, the fixed plate 35 and the positioning shaft 33 are lowered and inserted into the positioning slot 11 by the force of the spring 34. Then, the top button 32 is turned to make the positioning shaft 33 continue to descend, thereby firmly inserting it into the positioning slot 11. At the same time, the top button 32 is fixed with the limiting cylinder 36, completing the convenient docking of the two steel pipes 10 and the connecting pipe 20.

[0043] During subsequent disassembly, pull the positioning shaft 33 upwards, and then pull the steel pipe 10 out of the connecting fitting 20.

[0044] The present invention has been described above by way of example in conjunction with the accompanying drawings. Obviously, the specific implementation of the present invention is not limited to the above-described manner. Any non-substantial improvement made by adopting the inventive concept and technical solution of the present invention, or the direct application of the inventive concept and technical solution of the present invention to other occasions without modification, shall be within the protection scope of the present invention.
