Description

Technical Field

[0001] The invention relates to the field of steel structure fixing, and in particular to a locking device used for connecting and fastening building steel structures. Background Art

[0002] Steel structure is one of the more common structural forms in modern construction projects. Steel structure is mainly composed of beams, steel columns, steel trusses and other components made of steel sections and steel plates, and usually needs to be connected with connectors.

[0003] During the construction of building steel structures, locking devices are often required for reinforcement. Existing steel structure components or parts are usually connected by welds, bolts or rivets. During long-term use of bolts, rivets and welding methods, since only a single locking method is used, they are prone to loosening and falling off due to vibration, resulting in insufficient locking force; at the same time, after being fixed to the steel structure body for a long time, bolts and rivets are prone to bite together with the steel structure body and cannot be separated at a later stage. During disassembly and assembly at a later stage, forced destruction is often required, which is easy to be inconvenient for disassembly and assembly. Summary of the invention

[0004] In order to solve the technical problems of insufficient locking force and inconvenient later disassembly and assembly, the present invention provides a locking device for fastening the connection of building steel structures.

[0007] The locking mechanism includes a loading plate and a support rod, one end of the support rod is connected to the moving seat, the other end of the support rod is connected to a main rotating gear, the outer side of the main rotating gear is meshed with a sub-rotating gear, the inner side of the sub-rotating gear is connected to a rotating rod, the end of the rotating rod away from the sub-rotating gear is connected to a first rotating disk, the surface of the first rotating disk is sleeved with a transmission chain belt, and the other end of the transmission chain belt is connected to a second rotating disk; A rotating rod frame is connected to the inner side of the second rotating disk, the top of the rotating rod frame is connected to an adjusting shaft seat, the outer side of the adjusting shaft seat is connected to a moving shaft rod, the top of the moving shaft rod is installed with a moving axis, the outer side of the moving axis is connected to a receiving rod, the end of the receiving rod away from the moving axis is connected to a fixed axis, the outer side of the moving axis is connected to a limiting rod, the end of the limiting rod away from the moving axis is connected to a locking plate, and a resistance block is arranged on the surface of the locking plate.

[0008] As a further improvement of the above scheme, the top end of the adjusting screw is connected to the adjusting block, and the rotation of the adjusting screw drives the adjusting block to move. There are four groups of connecting shafts, and the four groups of connecting shafts are arranged in a diamond shape. The four groups of connecting shafts move to change the angle.

Multiple groups of steel structures placed in parallel can be locked at the same time. At the same time, the universal joint head can move in the base under the universal joint to adjust at multiple angles, so that the steel structure positioned by the universal adjustment mechanism can be flexibly adjusted in angle.

[0015] Compared with the prior art, the present invention has the following beneficial effects: 1. The adjusting and fastening mechanism in the present invention performs transverse locking on the steel structure, and the locking mechanism performs longitudinal locking on the steel structure, thereby realizing multi-directional locking of the steel structure and ensuring the stability of the locking. At the same time, when the steel structure needs to be disassembled and assembled, the present invention only needs to reversely rotate the adjusting screw on the adjusting and fastening mechanism to realize the disassembly and assembly of the steel structure, thereby preventing the problem that traditional bolts and rivets are easily bitten together with the main body of the steel structure after being fixed to the main body of the steel structure for a long time, and cannot be flexibly disassembled and assembled in the later stage.

[0016] 2. The present invention innovatively proposes an adjusting and fastening mechanism, which is relatively deflected by two sets of relative fastening plates. The two sets of relative fastening plates firmly clamp and bite the steel structure passing through the cavity between the device platform surfaces, thereby realizing the locking and fastening of the steel structure. At the same time, when the adjusting and fastening mechanism moves, the adjusting support mechanism and the locking mechanism are synchronously driven to move through the connecting rod, thereby realizing the synchronous locking of the locking mechanism, improving the tightening and locking effect, realizing the coordination between the structures, and improving the work efficiency.

[0017] 3. The present invention innovatively proposes an adjusting support mechanism and a locking mechanism. The locking plate fixes and locks the steel structure in the cavity between the device platform surfaces. Due to the setting of the resistance block, the friction between the locking plate and the steel structure is increased to ensure the stability of the locking. At the same time, the adjusting support mechanism cooperates with the adjusting fastening mechanism to drive the locking mechanism to lift the height and lock, thereby improving the locking efficiency.
