Description

Connecting device convenient to disassemble and assemble Technical Field The utility model relates to the technical field of laser direction indicator installation, in particular to a connecting device convenient to disassemble and assemble. Background In the engineering construction fields of mine development tunnel and road construction excavation tunnel, etc., the laser direction indicator is used as key measuring equipment, the convenience of erection and adjustment directly influences the construction efficiency and engineering quality, in the traditional technology, the fixing of the laser direction indicator usually adopts a cement grouting bolt fixing mode, the mode needs to inject cement slurry after the surface of a rock wall or tunnel is drilled, equipment can be installed after the cement slurry is solidified, and the method has the following defects: The installation is complex and time-consuming, cement grouting needs to undergo a plurality of steps such as drilling, grouting, curing and solidifying, the construction period of a single fixed point is as long as a plurality of hours, and the engineering time cost is obviously increased; The adjustment flexibility is poor, namely once the pointing position of the laser pointing instrument is fixed, if the pointing position needs to be finely adjusted or moved to a new position, the original cement base needs to be destroyed and re-constructed, so that repeated disassembly and assembly of equipment are difficult, and the dynamic construction requirement is difficult to adapt; therefore, the utility model provides a connecting device convenient to assemble and disassemble to solve the problems in the prior art. Disclosure of utility model Aiming at the problems, the utility model provides the connecting device convenient to disassemble and assemble, which has the advantages of simple structure, reliable use and convenient disassembly and assembly, can lighten the labor intensity of installing the laser direction indicator, saves time and improves the construction progress. The connecting device comprises a locking buckle and a fixed bracket, wherein the locking buckle is used for locking the fixed bracket on a connecting base rod, the fixed bracket comprises a first bracket and a second bracket, the second bracket is movably arranged below the front side of the first bracket, and one end of the second bracket is used for installing a laser direction indicator; The locking buckle comprises a locking block and a buckle, wherein two ends of the buckle respectively penetrate through two ends of the inside of the locking block and are fixed through threads, and the first bracket and the connecting base rod penetrate between the locking block and the buckle. The further improvement is that the connecting base rod comprises a supporting anchor rope and an anchor rod. The further improvement is that the two ends of the buckle are respectively provided with external threads, and the two ends of the buckle respectively penetrate through the two ends of the inside of the locking block and are locked with the external threads in an adapting way through nuts. The device is further improved in that a sleeve is arranged below the front side of the first bracket, one end of the second bracket penetrates through the sleeve, a fastening bolt is arranged on the sleeve in a threaded mode, and the fastening bolt is used for fixing the second bracket.
