The utility model discloses a side slope deformation detection device which comprises a supporting plate, a limiting mechanism and a rotating mechanism. The limiting mechanism comprises a detection strip, a first rotating shaft and an extension strip, the first rotating shaft is rotatably arranged at one end of the detection strip, the outer wall of the first rotating shaft fixedly penetrates through the outer wall of the extension strip, a second rotating shaft is rotatably arranged at the top end of the detection strip, a limiting rotating plate is arranged on the outer wall of the second rotating shaft, and a through hole is formed in the top end of the limiting rotating plate; a connecting plate is arranged at the top end of the positioning rod, and a spring is connected to the bottom end of the connecting plate; the rotating mechanism comprises a connecting rotating rod rotatably installed on the supporting plate, and the detection strip is arranged on the outer wall of the connecting rotating rod. When the limiting rotating plate is rotated to drive the positioning rod to move to the limiting hole in the top end of the extension strip, the outer wall of the positioning rod can be pushed to be clamped to the inner wall of the limiting hole through springback of the spring, the detection strip and the extension strip are limited and clamped, and the device is easy to unfold and operate and high in working efficiency.

A device is provided for performing a pressure test on a battery module. The device may include a module case in which battery cells are accommodated, a pressure plate installed in a middle portion of the module case in a width direction and configured to pressurize the battery cells toward the module case, a pressure driver configured to apply a pressure to the pressure plate, and a controller configured to control a pressure force and a pressure pattern with respect to the battery cells. The pressure plate may be configured to simulate expansion and contraction of the battery cells by repeatedly pressurizing and depressurizing the battery cells.

The utility model provides a box body deformation measuring tool, which comprises a supporting piece, a movable piece and a buffer structure, and is characterized in that the supporting piece is placed on the bottom surface in a box body during measurement and supports the movable piece through the buffer structure; the buffer structure is used for enabling the movable part and the supporting part to be relatively static under the condition that no other box body is stacked on the box body; under the condition that other box bodies are stacked on the box body, the moving distance of the movable piece towards the bottom face relative to the supporting piece is associated with the bottom deformation amount of the box body, adjacent to the movable piece, in the other box bodies; and the buffer structure is also used for keeping the moving part still at the moved position.

The utility model belongs to the technical field of corrugated board production, particularly relates to a corrugated board warping detection device, and provides the following scheme aiming at the problems that in the prior art, after a corrugated board is produced, the warping degree of the corrugated board needs to be detected, but the corrugated board cannot be adapted according to corrugated boards with different thicknesses during detection. The device comprises a base; the supporting plate is fixedly connected to the top of the base; according to the corrugated board detection device, a corrugated board is placed on the base, the electric push rod is controlled to work, a gap is formed between the detection board and the base along with movement of the corrugated board, when the corrugated board completely penetrates through the gap, it can be guaranteed that the corrugated board is not warped, and the detection efficiency is improved. And meanwhile, the motor works to control the detection plate to ascend, the corrugated boards with different thicknesses can be conveniently adapted by controlling the gap between the detection plate and the base, and detection is convenient.

The utility model discloses a device for measuring surfacing deformation of a tube plate. The device comprises channel steel, the bottom of the channel steel is provided with a rectangular groove, two sides of one end of the channel steel are respectively provided with a first pair of oblong hole grooves, and two sides of the other end of the channel steel are respectively provided with a second pair of oblong hole grooves; one of the supporting shafts is placed in the first pair of oblong hole grooves, and the other supporting shaft is placed in the second pair of oblong hole grooves; one end of each connecting rod is connected to one end of the corresponding supporting shaft; one end of each spring is connected to the other end of the corresponding connecting rod; the counterweight parts are respectively hung at the other ends of the springs; the pair of sliding block nuts is embedded in the rectangular groove; the positioning studs penetrate through the through holes of the sliding block nuts and are fixed together with the sliding block nuts; the sliding block is embedded in the rectangular groove; a support column; a measuring scale; and a chuck. The device can unify the measurement basis, improves the accuracy of the measurement result, and is suitable for measuring the surfacing deformation of various workpieces.
