This invention discloses a reinforced concrete joint inspection device, including a fixed base and an inspection component mounted on the fixed base for inspecting the joint structure. A bracket is welded to the back of the fixed base, and a rotating shaft is movably connected to the side of the bracket. A torsion spring is installed between the outer circumference of the rotating shaft and the side of the bracket. A lever is fixed to the outer circumference of the rotating shaft by a pin, with one end of the lever movably connected to an adjusting plate and the other end of the lever movably connected to a detection roller. The inspection component includes a guide plate fixed to the back of the fixed base by screws and a scale rod movably connected to the side of the guide plate. When the inspection roller encounters a protrusion on the transverse joint surface caused by pull, the lever rotates around the rotating shaft. Due to the different distances from the rotating shaft to the two ends of the lever, the lever principle amplifies the minute displacement of the inspection roller, making the change in the scale value of the scale rod relative to the guide plate more obvious, thus enabling more accurate detection of minute deformation defects on the joint surface.

The utility model provides a kind of material box.The material box includes: bottom plate, along first direction, bottom plate has oppositely arranged first end and second end;Handle, the first end of bottom plate and the second end of bottom plate are all provided with at least one handle, handle includes connecting portion, inclined portion and gripping portion, the first end of connecting portion is connected with bottom plate, the first end of inclined portion is connected with the second end of connecting portion, the second end of inclined portion extends obliquely away from the center of bottom plate, gripping portion includes gripping section and extension section, the first end of extension section is connected with inclined portion, the second end of extension section is connected with gripping section, and extension section and vertical plane present first included angle α, α The value range is 0 °≤α≤10 °.The technical scheme of the utility model can solve the problem that the distance between hand and the edge of battery piece is too close during the carrying process of the material box of prior art, which is easy to touch the edge of battery piece during lifting, resulting in the problem of rising of work loss rate of battery piece.
