Description
Technical Field
[0001] The utility model relates to the technical field of connecting joints, in particular to a mechanical connecting joint for steel bars. Background Technique
[0002] The mechanical connecting joint of steel bars is a connecting method that transfers the force in one steel bar to another through the mechanical biting action of the connecting piece or the bearing pressure on the end face of the steel bar. This connecting technology is called the "third-generation steel bar joint" after binding and electric welding.
[0003] In the prior art, when mechanically connecting steel bars, the connecting heads used are mostly threaded connections. For threaded connections, workers are also required to process threads on the outer wall of the steel bars, and then use threaded joints for connection. Manual thread processing takes a long time, especially for large-scale and high-intensity processing tasks, which will lead to a reduction in work efficiency. Content of the Utility Model
[0004] The utility model mainly provides an aluminum cover plate with high-precision drilling that can automatically sweep off debris.
[0005] To achieve the above object, the utility model adopts the following technical scheme: A mechanical connecting joint for steel bars, including a connecting ring. Two bolts are fixedly installed on the outer wall of the connecting ring. The outer walls of both bolts are threadedly connected with fixing rings. Square holes are opened on the outer walls of both fixing rings. Holes are opened on the inner walls of both square holes. Movable rods are movably inserted into the inner walls of both holes. Movable rings are fixedly sleeved on the outer walls of both movable rods. First, the threads on the inner wall of the fixing ring can be rotationally connected with the bolts, so that the two fixing rings are connected through the connecting ring. The connecting ring can be freely disassembled, which is more convenient for workers to inspect it. Secondly, the movable rods are inserted into the holes on the inner wall of the square hole, and the movable rods can rotate in the holes. Secondly, the movable rings are connected to the movable rods, and the movable rings can rotate through the movable rods, which can more intuitively connect and place two steel bar bodies.
[0006] Preferably, threaded holes one are opened at the tops of both movable rings. Screws one are threadedly connected to the inner walls of both threaded holes one. At this time, the fixing rings and the movable rings are in contact. By rotating the screws one into the threaded holes one, pressure is applied to the inside for fixation. When connecting, just tighten the screws one with an ordinary wrench or a special tool to complete, which greatly reduces the labor intensity and saves time.
[0007] Preferably, threaded holes two are opened at the tops of both movable rings. Threaded holes three are opened at the tops of both fixing rings. Align the threaded holes two and the threaded holes three to facilitate the installation of the device.
[0008] Preferably, screw two is threadedly connected to the inner surface walls of both of the two threaded holes two, and the outer surface walls of both of the two screws two are rotatably inserted into the inner surface walls of the two threaded holes three. After the threaded hole two and the threaded hole three are aligned, by simultaneously rotating the screw two into the threaded hole two and the threaded hole three, the movable ring and the fixed ring are connected and fixed, which can effectively resist vibration and deformation and reduce the risk of structural damage.
[0009] Preferably, the inner surface walls of both of the two fixed rings are provided with reinforcing bar bodies, and the two reinforcing bar bodies are respectively placed inside the fixed rings.
[0010] Preferably, threaded holes four are opened on the outer surface walls of both of the two fixed rings, and the two threaded holes four are located at the bottom of the fixed rings.
[0011] Preferably, screw three is threadedly connected to the inner surface walls of both of the two threaded holes four. By rotating the screw three into the threaded hole four, pressure is applied to the reinforcing bar body, so that the reinforcing bar body is subjected to frictional force, strengthening the stability of the connection of the reinforcing bar body. The fastening of the screw three can ensure the tight connection between the reinforcing bar bodies without gaps, thereby preventing the loosening and slipping of the reinforcing bar bodies.
[0012] Compared with the prior art, the advantages and positive effects of the present utility model are as follows.
[0013] 1. In the present utility model, through the threaded connection between the bolt and the fixed ring, the two fixed rings are connected through the connecting ring. When repairing, replacing or upgrading the equipment, the bolt can be quickly disassembled and reinstalled, thus greatly saving time and labor costs. Secondly, the movable ring can rotate through the movable rod, which is more convenient for the staff to place the reinforcing bar body, and the placement position of the reinforcing bar body can be intuitively understood, making the connection tighter. Then, by simultaneously passing the screw two through the threaded hole two and the threaded hole three to connect the movable ring and the fixed ring, the tight connection between the reinforcing bars can be ensured, effectively preventing the sliding and tilting of the reinforcing bars, thereby improving the overall strength of the connection.
[0014] 2. In the present utility model, first, by rotating the screw one into the threaded hole one and simultaneously rotating the screw three into the threaded hole four, the screw one and the screw three are tightened towards the reinforcing bar body respectively, increasing the Ma friction received by the reinforcing bar body and ensuring the durability and stability of the connection.
