[0002] Building steel structure fasteners refer to connectors used to connect pipes and steel structures. They are mainly used to fix pipes to prevent them from shifting or falling off due to vibration or other factors during operation.

[0003] In the existing light steel structure construction process, because it involves a lot of steel structures, and different steels are fixed, especially some cantilevered steel pipes and plate-like plates are not convenient to fix. The common fixing method on the market is to use cantilever fasteners, and the common fasteners are simply set with bolts when fixing the top plate-like plates, without anti-slip and anti-loosening structures, and there is no anti-slip structure inside the buckle of the fastener. Especially in typhoon-prone areas, there will be risks of bolt loosening and buckle shaking over time, which will affect the stability and firmness of the light steel structure. Therefore, there is an urgent need for a fastener with a firm structure, easy installation, and strong anti-slip properties;

Second, the utility model discloses a reinforced fastener for a prefabricated light steel structure. Anti-slip strips are set on the annular inner wall after the upper fastener and the lower fastener are clamped, which is conducive to increasing the friction between the round tube and the inner wall of the fastener, making the structure more firm and stable.

[0030] In this embodiment: by setting a stabilizing seat 1 fixed at the bottom of the opening and closing structure 2, the stability of the fastener being placed is increased; by setting the opening and closing structure 2, the effect of clamping the pipe can be achieved; by setting the snap-fit ​​structure 3, when the opening and closing structure 2 is closed, a connecting block 32 fixed at the bottom of the fixing block 31 and a connecting member 33 fixed to the rotating plate 34 are set, and then a stretching structure 4 is set between the opening and closing structure 2 and the snap-fit ​​structure 3, so as to achieve the purpose that the rotating plate 34 part in the snap-fit ​​structure 3 can be pulled back; by setting a supporting block 35 and fixing the stabilizing seat 1, the rotation of the rotating plate 34 can be supported; the downward pressure of the connecting block 32 will cause the connecting member 33 to partially rotate to the front side; when the connecting block 32 passes the connecting member 33, the rotating plate 34 part is rebounded by the stretching structure 4, and the fixed block 31 part is limited, so as to achieve the purpose of limiting the movement of the opening and closing structure 2, thereby increasing the efficiency of the fastener installation.

[0031] Specifically, Figure 2 , Figure 3 , Figure 5 As shown, a fixing ring 41 is fixedly connected to the bottom of the rear side of the rotating plate 34 , and a movable block 42 is movably connected to the inner side of the fixing ring 41 .

When the rotating plate 34 is not controlled to rotate, the rebound block 46 will release the elastic potential energy to return the plug-in rod 45 to its original position.

[0035] Specifically, Figure 4 and Figure 5 As shown, the top of the stabilizing seat 1 is fixedly connected to a supporting seat 21 , and the rear side of the supporting seat 21 is fixedly connected to a rotating member 22 .

[0036] Specifically, Figure 4 As shown, a closing block 23 is fixedly connected to the front side of the rotating member 22 , the bottom of the closing block 23 is movably connected to the top of the support seat 21 , and the front side of the closing block 23 is fixedly connected to the rear side of the fixed block 31 .

[0037] In this embodiment: by setting a rotating member 22 fixed between the support seat 21 and the closing block 23, the purpose of the closing block 23 cooperating with the support seat 21 to rotate can be achieved. The user opens the closing block 23, places the pipe on the top of the support seat 21, and then pulls back the closing block 23 to press down the top of the pipe, thereby achieving the purpose of preliminary clamping of the pipe.

[0038] Specifically, Figure 4 As shown, a connection groove 5 is provided on the front side of the support seat 21 , the outer side of the rebound block 46 is movably connected to the inner side of the support seat 21 , and the outer side of the plug-in rod 45 is movably connected to the inner side of the support seat 21 .

[0039] Specifically, Figure 1 As shown, a protective shell 6 is bolted to the front side of the support seat 21 , the front side of the protective shell 6 is movably connected to the rear side of the rotating plate 34 , and the top of the protective shell 6 is movably connected to the bottom of the connecting block 32 .

[0040] In this embodiment: the connecting groove 5 opened by the support seat 21 is used to achieve the effect that the plug-in rod 45 and the rebound block 46 in the tensile structure 4 can be arranged on the inner side of the support seat 21, and the protective shell 6 bolted to the front side of the support seat 21 is provided to protect the tensile structure 4, and at the same time, the return of the rotating plate 34 can be supported.

The movable member 43 connected between the movable block 42 and the fixed member 44 also rotates accordingly, so that the plug-in rod 45 fixed with the fixed member 44 moves along with the rotation of the rotating plate 34, and the movement of the plug-in rod 45 will compress the rebound block 46 provided on the inner side of the support seat 21. When the rotating plate 34 is not controlled to rotate, the rebound block 46 will release the elastic potential energy to make the plug-in rod 45 return to its original position, so as to achieve the purpose of partially pulling back the rotating plate 34. By setting the fixing 1 of the support block 35 and the stabilizing seat, the rotation of the rotating plate 34 is supported. The downward pressure of the connecting block 32 will cause the connecting member 33 to partially rotate to the front side. After the connecting block 32 passes through the connecting member 33, the rotating plate 34 is partially rebounded by the tensile structure 4, which limits the fixed block 31 partially, so as to achieve the purpose of limiting the movement of the closing block 23, thereby increasing the efficiency of the fastener installation.
