The application relates to the technical field of battery safety testing, and discloses a new energy lithium battery impact testing device, which comprises a base, a rack arranged on the base and a testing guide rod, further comprises a lifting mechanism arranged on the base and a testing mechanism slidingly assembled on the testing guide rod; the testing mechanism comprises a testing plate, the bottom of the testing plate is fixed with a testing seat, and the bottom of the testing seat is fixed with a testing block for planar impact on the lithium battery. The new energy lithium battery impact testing device is provided with an adjusting assembly capable of horizontally adjusting the position, a lifting assembly capable of up-down telescopic adjustment and an impact assembly integrating an impact block and a puncture needle in the testing seat, so that the device can be freely switched among three modes of planar impact, point impact and puncture impact, the overall impact, local point impact and puncture test on the lithium battery can be completed without disassembling and replacing any tool parts, and the diversified and all-round lithium battery safety performance test demand is met.

This utility model discloses a construction solid waste compression and processing device, including a processing chamber, a control chamber, and a pressure plate. The control chamber is located on the top of the processing chamber, and a hydraulic cylinder is installed inside the control chamber. The output end of the hydraulic cylinder is fastened to the pressure plate. A conveying trough is opened on one side of the processing chamber, and a connecting shaft is rotatably connected inside the conveying trough. A base plate and a baffle are provided on the connecting shaft. A mounting seat is provided at the bottom of the base plate, and an electric push rod is installed inside the mounting seat. A limit plate is fixedly installed on one side of the interior of the processing chamber, and a rotating motor is installed at the bottom of the limit plate. In this utility model, the electric push rod, in conjunction with the mounting seat, drives the base plate and the connecting shaft to rotate. The rotating motor drives the slide to move, and the slide subsequently drives the moving plate to rise and fall. When the electric push rod at the top of the moving plate rises and falls, the construction waste flips over and is discharged from the interior of the processing chamber through the baffle.

The utility model discloses an embodiment relates to a kind of lifting movement mechanism of three comprehensive test box, box fixed bracket is set below the lifting movement mechanism of three comprehensive test box;Test box body is fixed above box fixed bracket;The whole of fixed test box body and box fixed bracket is placed in screw fixed frame;Horizontal moving platform is fixedly connected at the bottom of screw fixed frame;Driving device is fixed in box fixed bracket;Turbine screw lifting machine assembly is set in screw fixed frame;Driving device drives turbine screw lifting machine assembly synchronous lifting operation to lift box, its advantage is that: stable structure, stable operation, little by environmental factor, support greater load, lifting height is higher, with certain self-locking capacity, and precision control is high, structure is simple, solve in prior art, the technical problem of unstable operation, volume and load restriction, maintenance complex, potential leakage risk of traditional hydraulic scissor brace.
