[0032] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings. 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.

[0033] Reference Figure 1 , Figure 3 and Figure 4 An embodiment of this utility model is provided: a quick-connect fitting for steel structures, including a steel frame 1 and a steel frame 2. A plug-in mechanism 3 is provided between adjacent steel frames 1 and 2. The plug-in mechanism 3 is used to cross-join the steel frames. A reinforcement mechanism 4 is provided on the outside of the plug-in mechanism 3. The reinforcement mechanism 4 is used to reinforce the connection of the steel frames.

[0034] The insertion mechanism 3 includes an insertion block 31. The inner side of the insertion block 31 has a cross-shaped I-beam cavity structure. The insertion block 31 is made of Q355 carbon structural steel. The inner side of the insertion block 31 is located on the outer side of steel frame 1 and steel frame 2. Multiple welding plates 32 are fixedly connected to the outer side of the insertion block 31. Each welding plate 32 has a mating block 33 fixedly connected to its outer side. The outer edges of the mating blocks 33 are chamfered, and the edges of the mating blocks 33 are rounded. The mating blocks 33 are... Two reinforcing ribs 34 are fixedly connected to the side away from the welded plates 32. Locking components 35 are provided on the side away from the welded plates 32. The locking components 35 include two bolts 351. The inner sides of the two bolts 351 are threaded to the right and rear sides of the plug block 31, respectively. The inner sides of the two bolts 351 are both hexagonal groove structures. The locking components 35 also include two nuts 352. The inner sides of the two nuts 352 are threaded to the outer walls of the two bolts 351, respectively. The outer walls of the two nuts 352 are both hexagonal structures.

[0035] The top and bottom of the plug-in block 31 are provided with engaging components 36. The engaging components 36 include two engaging blocks 361. The two engaging blocks 361 are fixedly connected to the top and bottom of the plug-in block 31 respectively. The top and bottom of the plug-in block 31 are provided with engaging grooves 362. The adjacent of the multiple mating blocks 33 are provided with positioning components 37. The positioning components 37 include multiple positioning pins 371. The opposite sides of the multiple positioning pins 371 are fixedly connected to the adjacent of the multiple mating blocks 33 respectively. The outer side of the plug-in block 31 is provided with multiple positioning grooves 372.

[0036] Specifically, when the plug-in mechanism 3 is working, the cross-shaped cavity structure on the inner side of the plug-in block 31 is fitted onto the outer side of the steel frame 1 and the steel frame 2. Through the cooperation between the plug-in block 31 itself and the steel frame 1 and the steel frame 2, the initial connection between the two is achieved.

[0037] The welding plate 32 on the outside of the plug block 31 drives the docking block 33 to dock with the external structure. The chamfer and rounded edges on the outside of the docking block 33 reduce the docking resistance. The reinforcing rib 34 enhances the connection strength between the docking block 33 and the welding plate 32. Through the cooperation of the docking block 33 and the reinforcing rib 34, the structural stability of the docking part is improved.

[0038] In the locking assembly 35, the bolt 351 passes through the welding plate 32 and is threaded onto the plug block 31. The nut 352 is tightened into the locking position on the outer wall of the bolt 351. The internal hexagonal groove structure facilitates the tightening of the bolt 351, and the hexagonal outer wall facilitates the fastening of the nut 352. Through the cooperation of the bolt 351 and the nut 352, the plug block 31 is fixed to the steel frame.

[0039] In the engaging assembly 36, the engaging blocks 361 at the top and bottom of the plug-in block 31 are embedded in the engaging grooves 362 of the corresponding structure. The engagement of the engaging blocks 361 and the engaging grooves 362 restricts the up and down movement of the plug-in block 31.

[0040] In the positioning component 37, the positioning pins 371 between adjacent mating blocks 33 are inserted into the positioning grooves 372 on the outside of the plug-in block 31. Through the cooperation of the positioning pins 371 and the positioning grooves 372, the relative positions of the mating blocks 33 and the plug-in blocks 31 are ensured to be accurate. After the plug-in blocks 31 are fitted with the steel frame, the positioning component 37 first determines the mating position, the locking component 36 restricts the up and down movement, and the locking component 35 finally fixes the overall structure. The welding plate 32 and the mating blocks 33 assist in the external connection.

[0041] Reference Figure 1 , Figure 2 and Figure 5 The reinforcement mechanism 4 includes multiple extension columns 41, which are fixedly connected to each other on the opposite side of multiple docking blocks 33. Two grooves 42 are provided on the opposite side of each of the multiple docking blocks 33. Multiple support blocks 43 are fixedly connected to the top and bottom of the multiple extension columns 41, and buffer pads 44 are fixedly connected to the opposite side of each of the multiple support blocks 43.

[0042] Specifically, when the reinforcement mechanism 4 is working, multiple extension columns 41 are fixed on the side of the docking block 33 that is far away from each other. As the docking block 33 docks with the external structure, the extension columns 41 extend outward to increase the force-bearing area of ​​the docking part. Through the cooperation between the extension columns 41 and the docking block 33, the load-bearing capacity of the overall structure is improved. The groove 42 on the side of the docking block 33 that is far away from each other provides installation space for the extension columns 41, making the connection between the extension columns 41 and the docking block 33 more snug and reducing the structural gap. Through the cooperation between the groove 42 and the extension columns 41, the tightness of the connection between the two is enhanced.

[0043] The support blocks 43 at the top and bottom of the extension column 41 extend to both sides and abut against the external contact surface to disperse the pressure on the docking part and avoid excessive local stress. Through the cooperation of the support blocks 43 and the extension column 41, the force is evenly transmitted.

[0044] The buffer pad 44 on the side away from the support block 43 contacts the external contact surface. When the structure is subjected to force and vibrates and displaces, the buffer pad 44 deforms and absorbs part of the impact force. Through the cooperation between the buffer pad 44 and the support block 43, the impact of vibration on the overall structure is reduced.

[0045] After the docking block 33 docks with the external structure, the extension column 41 is simultaneously positioned. The support block 43 contacts the outside through the buffer pad 44, and the groove 42 ensures that the extension column 41 is installed firmly, working together at the docking part.

[0046] Working principle: Through the operation of the plug-in mechanism 3, the cross-shaped cavity structure on the inner side of the plug-in block 31 is fitted onto the outer side of the steel frame 1 and the steel frame 2, so that the two are initially connected. The positioning pins 371 between the adjacent docking blocks 33 are inserted into the positioning grooves 372 on the outer side of the plug-in block 31 to ensure that the relative position of the docking block 33 and the plug-in block 31 is accurate. The locking blocks 361 at the top and bottom of the plug-in block 31 are embedded in the locking grooves 362 of the corresponding structure to restrict the up and down movement of the plug-in block 31.

[0047] The bolt 351 of the locking component 35 passes through the welding plate 32 and is threaded onto the plug block 31. The nut 352 is tightened into the locking position on the outer wall of the bolt 351 to fix the plug block 31 to the steel frame. The welding plate 32 on the outside of the plug block 31 drives the docking block 33 to dock with the external structure. The chamfer and rounded edges on the outside of the docking block 33 reduce the docking resistance. The reinforcing rib 34 enhances the connection strength between the docking block 33 and the welding plate 32.

[0048] The reinforcement mechanism 4 begins to work. Multiple extension columns 41 extend outward along with the docking block 33 and the external structure, increasing the stress area of ​​the docking part. The groove 42 on the opposite side of the docking block 33 provides installation space for the extension columns 41, making the connection between the extension columns 41 and the docking block 33 more snug and reducing structural gaps. The support blocks 43 at the top and bottom of the extension columns 41 extend to both sides and abut against the external contact surface, dispersing the pressure on the docking part and avoiding excessive local stress. The buffer pad 44 on the opposite side of the support block 43 contacts the external contact surface and deforms when the structure is subjected to stress and vibrates and displaces, absorbing part of the impact force and reducing the impact of vibration on the overall structure.

[0049] The cross splicing of steel frame 1 and steel frame 2 is achieved through the plug-in mechanism 3, and the reinforcement mechanism 4 reinforces the connection of the steel frame, thus completing the quick plug-in connection of the steel structure and ensuring that the connection is stable and reliable.

[0050] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features.
