[0003] In traditional construction, beam clamps are generally used when the laser instrument needs to be fixed in the upper space. Existing beam clamps are generally directly connected and fixed to both sides of the beam through clamps and bolts, which are easy to loosen and fall off during use. Utility Model Content

[0004] In view of the technical problems in the prior art, the utility model provides a laser instrument supporting and fixing device, comprising a mounting plate, a laser instrument is installed at the bottom of the mounting plate, and a fixed clamping plate and a movable clamping plate are installed on the top of the mounting plate, the bottom end of the fixed clamping plate is fixedly connected to one end of the mounting plate, the bottom end of the movable clamping plate is slidably connected to the mounting plate and locked by an adjusting component, the fixed clamping plate and the movable clamping plate are relatively arranged, and a clamping space for fixing to a cross beam is formed therebetween, and also includes a locking mechanism, the locking mechanism includes two bending plates, the bending angles of the bending plates are 90° to 180°, the fixed clamping plate and the movable clamping plate are provided with through grooves running through the top ends, the bending parts of the two bending plates are respectively hinged to the top ends of the fixed clamping plate and the movable clamping plate through pin shafts, and the lower section of the bending part is rotatably installed in the through groove, and when the lower section of the bending part contacts the side wall of the cross beam, the upper section of the bending part abuts against the top surface of the cross beam.

[0005] Furthermore, the locking mechanism also includes two pressure plates, which are installed between the fixed splint and the movable splint. The two pressure plates are respectively connected to the fixed splint and the movable splint through telescopic rods, and the sides of the two pressure plates away from each other are respectively in contact with the lower sections of the two bending plates.

[0006] Furthermore, the locking mechanism also includes two springs, the two springs are respectively sleeved outside the two telescopic rods, and the two ends of the springs are respectively fixed with the clamping plate and the pressure plate or the movable clamping plate and the pressure plate abut.

[0010] Beneficial effects:

[0011] 1. In the utility model, the laser instrument can be fixed on the beam through the coordinated arrangement of the mounting plate, the fixed splint, the movable splint and the adjusting component. Combined with the arrangement of two bending plates with bending angles of 90° to 180°, the fixing device can be prevented from being separated from the beam by the rotation of the bending plates, thereby improving the fixing effect. Specifically, when fixing the laser instrument, the fixed splint and the movable splint are in contact with both sides of the beam and are locked by the adjusting component. At the same time, the two sides of the beam will squeeze the lower section of the bending plate, so that the upper section of the bending plate rotates around the pin shaft and extends out of the fixed splint and the movable splint, and then is pressed against the top of the beam. The vertical displacement of the fixing device can be limited by the bending plate. Even if the movable splint and the fixed splint are loosened from the side wall of the beam, the bending plate can effectively prevent the laser instrument from falling.

[0012] 2. In the utility model, the two pressing plates are arranged to increase the contact area between the lower section of the bending plate and the side wall of the beam, and the rotation of the bending plate can be facilitated; the two springs are arranged to utilize the elastic force of the springs to improve the fixing effect, and prevent the adjustment component from loosening, and also facilitate the resetting of the pressing plate and the bending plate, so as to facilitate the next use of the fixing device; combined with the arrangement of the slide groove and the slider, the mounting plate and the beam can slide relatively freely, avoiding the influence of the vibration of the beam on the measurement of the laser instrument, improving the measurement accuracy, and also better protecting the laser instrument. Specifically, when the beam vibrates, the vibration energy will be eliminated through the movement of the two springs and the slider and the slide groove, thereby avoiding its transmission to the mounting plate.

[0013] 3. In the utility model, by setting the serrated rubber block, the friction resistance between the upper section of the bending plate and the top of the beam can be increased to prevent loosening and falling, while also protecting the surface of the beam from being damaged. In addition, the elasticity of the serrated rubber block can be used to reduce the impact of vibration on the laser instrument.

[0014] 4. In the utility model, by setting the bending angle of 135°, it is possible to facilitate the installation and coordination between the fixing device and the beam, and at the same time, another relative clamping space can be formed between the upper section of the bending plate and the mounting plate, thereby achieving clamping between the bottom surface and the top surface of the beam, effectively preventing the fixing device from loosening and further improving the fixing effect.
