[0002] Steel structures are structures primarily composed of steel materials and are one of the main types of building structures. The structure mainly consists of steel beams, steel columns, steel trusses, and other components made of shaped steel and steel plates, which are typically connected by welding, bolts, or rivets.

[0003] Existing steel structures are usually assembled from various post-construction components. However, the assembly of multiple parts can lead to unstable connections at the joints. For example, cross-shaped steel structures are prone to breakage at the intersections, posing a safety hazard. Utility Model Content

[0016] The following are specific embodiments of the present invention, which are described in conjunction with the accompanying drawings. However, the present invention is not limited to these embodiments.

[0017] like Figures 1 to 4 As shown, this utility model can be implemented through the following embodiments: A steel structure that is easy to assemble includes a crossbar 1 and a sleeve 2. The crossbar 1 is provided with an assembly part 11, and the assembly part 11 extends to a positioning sleeve 12. The sleeve 2 is provided with an assembly part 21, and the assembly part 21 extends to a positioning sleeve 22. The positioning sleeve 22 is inserted into the positioning sleeve 12. The positioning sleeve 12 has positioning grooves 121 on its upper and lower sides. The crossbar 1 is inserted into a vertical bar 3 in the vertical direction. The vertical bar 3 extends to a fixing sleeve 31. A locking rod 4 is inserted into the end of the fixing sleeve 31 of the vertical bar 3. A locking block 5 is installed in the fixing sleeve 31. The positioning sleeve 12 has a through hole 122, and the positioning sleeve 22 has a through hole 221.

[0018] The horizontal bar 1 and the sleeve bar 2 are connected by inserting the second positioning sleeve 22 into the first positioning sleeve 12, which has a large contact area and improves the stress that can be withstood; the positioning groove 121 is used to provide the insertion position of the fixing sleeve 31 of the vertical bar 3, improving the assembly efficiency; the locking block 5 is used to pass through the first through hole 122 and the second through hole 221, thereby realizing the fixed connection between the horizontal bar 1 and the sleeve bar 2 and preventing relative sliding between the horizontal bar 1 and the sleeve bar 2.

[0019] like Figure 3 As shown, a reset groove 32 is formed inside the fixed sleeve 31, and a reset spring 6 is installed inside the reset groove 32. The two ends of the reset spring 6 are connected to the fixed sleeve 31 and the locking block 5, respectively. The reset spring 6 provides an inward pushing force to the locking block 5, so that when the locking rod 4 is disengaged from the fixed sleeve 31, the locking block 5 disengages from the through hole 122 and the through hole 221, making it easy for the user to disassemble.

[0020] like Figure 2 and Figure 3 As shown, there are two locking blocks 5. The bottom surfaces of the locking blocks 5 are in contact with each other. One side of the bottom surface of the locking block 5 has an inclined surface 51. The locking rod 4 extends to a pushing rod 41, and the end of the pushing rod 41 is set as a triangular head 42. The inclined surface 51 on one side of the bottom surface of the locking block 5 facilitates the separation of the locking block 5 with the triangular head 42 at the pushing rod 41, thereby pushing the locking block 5 into the through hole 122 and the through hole 221, which is convenient for assembly. The bottom surfaces of the locking blocks 5 are in contact with each other, which makes it easy to leave enough space for the locking blocks 5 to move, so that the locking blocks 5 can be locked into the through hole 122 and the through hole 221, realizing the fixed connection between the crossbar 1 and the sleeve rod 2.

[0021] like Figures 1 to 3 As shown, the vertical rod 3 has a groove 33 inside the fixing sleeve 31, and a countersunk screw hole 34 is formed on the wall of the groove 33. An insertion hole 421 is formed at the triangular head 42, and a bolt 7 passes through the countersunk screw hole 34 and the insertion hole 421. The groove 33 allows the pushing rod 41 to penetrate deep into the vertical rod 3, increasing the contact area between the locking rod 4 and the vertical rod 3 and improving the stability of the connection. The bolt 7 is used to fix the pushing rod and the vertical rod 3, so that the locking rod 4 is fixed to the vertical rod 3, preventing the locking rod 4 from detaching from the vertical rod 3 and ensuring a stable connection. At the same time, the installation position of the bolt 7 is far away from the intersection, the bolt 7 bears less stress, and the steel structure is not easy to tear at the bolt 7.

[0022] like Figure 2 and Figure 4 As shown, a guide rod 52 is provided on the locking block 5, and a guide hole 311 is provided inside the fixing sleeve 31. The guide rod 52 is located inside the reset spring 6. The guide rod 52, in conjunction with the guide hole 311, guides the locking block 5 to move, preventing the locking block 5 from shifting during the process of the push rod 41 pushing the locking block 5.

[0023] The working principle of this utility model is as follows: Align and insert the positioning sleeve 12 of the horizontal bar 1 and the positioning sleeve 22 of the sleeve bar 2, then insert the vertical bar 3, and then insert the locking rod 4. The pushing rod 41 on the locking rod 4 enters the fixing sleeve 31 and pushes the locking block 5 outward. The outwardly moved locking block 5 is engaged with the through hole 122 and the through hole 221, realizing the fixed connection between the vertical bar 3, the horizontal bar 1 and the sleeve bar 2. The bolt 7 passes through the pushing rod 41 and the vertical bar 3 to realize the fixed connection between the vertical bar 3 and the locking rod 4, thus completing the assembly.

[0024] The specific embodiments described herein are merely illustrative examples illustrating the spirit of this utility model. Those skilled in the art to which this utility model pertains may make various modifications or additions to the described specific embodiments or use similar methods to substitute them, without departing from the spirit of this utility model or exceeding the scope defined by the appended claims.

[0025] Although this document uses a variety of terms, the possibility of using other terms is not excluded. These terms are used merely for the convenience of describing and explaining the essence of this invention; interpreting them as any additional limitation would contradict the spirit of this invention.
