Embodiment approach

[0023] As the first embodiment of the clamping module 4 in the present invention, the clamping module 4 includes a support plate 41, a No. 1 roller 42, and a ratchet pawl device. The No. 1 cylindrical hole 12 is provided with two sets of support plates 41 One end of the support plate 41 is fixedly connected in the No. 1 cylindrical hole 12, and the other end of the support plate 41 is connected to the No. 1 roller 42 through a ratchet pawl device; During work, the steel bar is inserted in the No. 1 cylindrical hole 12, and the arc-shaped protrusion on the surface of the steel bar pushes the arc-shaped tooth 421 on the cylindrical surface of the No. 1 roller 42 to move, and the arc-shaped tooth 421 drives the No. 1 roller 42 to rotate. Both sides of the steel bar are squeezed by two groups of No. 1 rollers 42, and because the No. 1 rollers 42 are connected on the support plate 41 through the ratchet pawl device, the steel bar can only be inserted from the No. 1 cylindrical hole ...

Abstract

The invention belongs to the technical field of engineering construction, in particular to an angle adjustable steel bar quick connecting sleeve. The connecting sleeve comprises connecting sleeve bodies, a spring, a locking nut, a locking handle, a clamping module and a screw. Face teeth are arranged in a round area on the stepped surface at one end of each connecting sleeve body. The other end ofthe screw is rotatably connected to one end of the locking handle. A rotating shaft hole in the locking handle is eccentrically disposed with the cylindrical surface. A first cylindrical hole is formed in the end surface at the other end of the connecting sleeve body. The clamping module is arranged in the first cylindrical hole and used for clamping and locking steel bars inserted into the connecting sleeve bodies. Due to the fact that the face teeth are arranged at one end of each connecting sleeve body, and the rotating shaft hole in the locking handle is eccentrically arranged with the cylindrical surface, the angle between two connecting sleeve bodies can be adjusted. The clamping module is arranged in the first cylindrical hole to clamp and lock the steel bars, and finally fasteningconnection of the two steel bars can be achieved.

Description

technical field [0001] The invention belongs to the technical field of engineering construction, in particular to an angle-adjustable steel bar quick connection sleeve. Background technique [0002] In the prior art, concrete methods such as welding, binding and overlapping, and mechanical connection can be used for connection of steel bars. The connection of prefabricated reinforced concrete components is usually to realize the connection of steel bars first, and then realize the connection of other parts on this premise. For example, in the connection process of prefabricated components, the steel bars are connected first, and then the surrounding structures such as concrete are poured and connected. If electric welding is used, equipment such as electric welding machine and power cord are needed. The process is complicated and inconvenient to use, especially when working at heights, it is even more inconvenient to pull the power cord and electric welding machine and othe...
