This invention discloses a mounting structure for a commercial vehicle's upper step assembly, including a cab-end step front mounting bracket assembly, a cab-end step rear mounting bracket assembly, and a chassis-end step mounting bracket assembly. The cab-end step front mounting bracket assembly includes a first main body, which is formed by bending tubing. The chassis-end step mounting bracket assembly includes a second main body, with a first bent pipe connected to one end face of the second main body, and two second bent pipes connected to the same end face. The second main body is fixed to the chassis-end step via a third upper connection point, a third middle connection point, and the second bent pipes are fixed to the chassis-end step via a third lower connection point. This invention improves the connection strength of the step assembly mounting structure while ensuring its performance.

The utility model relates to the technical field of laser cutting machines, in particular to a laser cutting machine base convenient to position, and solves the problems that in the prior art, when a laser cutting machine is mounted and connected through a base, the mounting and dismounting convenience is poor, the laser cutting machine is inconvenient to fix after being quickly butted, and the working efficiency is high. And therefore, the mounting and dismounting connection efficiency of the laser cutting machine is reduced. A laser cutting machine base convenient to position comprises a movable base, a bearing seat and a mounting plate arranged at the top of the bearing seat, and the bottom of the bearing seat is connected with the top of the movable base through a lifting module; the four corners of the top of the mounting plate are each provided with a plurality of mounting holes used for being connected with a laser cutting machine. And a positioning structure detachably connected with the mounting plate is arranged at the top of the bearing seat. According to the utility model, the structure is reasonable, rapid positioning connection is carried out after pre-installation, the efficiency of positioning connection is greatly improved, and the convenience of assembly and disassembly connection is improved.

The utility model discloses a dust-free device for rapidly and accurately cutting aerated blocks, the four corners of the top of a bottom cutting table are detachably connected with a top frame through connecting square pipes, a hydraulic cylinder is installed in the middle of the inner side of the top frame, and the telescopic end of the bottom of the hydraulic cylinder is fixedly connected with a cutting tool apron; the bearing table can slide on the bottom cutting table in a sliding mode through the sliding rail and the rail groove, the positions of the bearing table and the aerated block placed on the inner side of the bearing table can be conveniently and rapidly adjusted, the bearing table drives the mark pointer to move when moving, and the aerated block can be conveniently and rapidly cut. The cutting position of the aerated block is precisely positioned by means of the alignment scale marks, the size precision of the aerated block after follow-up cutting is ensured, meanwhile, the cutting position of the aerated block can be verified before cutting by means of the horizontal ray lamp at the cutting pressing knife, and the cutting precision of the follow-up aerated block is further ensured.

The invention relates to the technical field of lighting street lamps, in particular to an LED street lamp with a waterproof power source cavity, the LED street lamp comprises a mounting base, a lamp pole and an LED lamp, the lamp pole is fixedly arranged at the top of the mounting base, and the LED lamp is fixedly arranged at the top end of the lamp pole. The sealing bottom plate is arranged at the bottom of the connecting frame, the power wire is connected with the LED lamp and electronic elements in the power box through the interior of the sealing bottom plate, openings are not formed in the top and the side edge of the power box, and therefore the waterproof effect of the power box can be improved to a great extent; vertical vibration received by the power box is filtered through a connecting damper arranged between the upper mounting frame and the lower mounting frame, and transverse vibration received by the power box is filtered through a plurality of micro dampers arranged in the two fixing frames, so that the power box can effectively resist vibration and impact; and internal electronic components are protected from being damaged.
