Description

Technical Field

[0001] This utility model relates to the technical field of power supply testing devices, specifically a power supply safety testing device. Background Technology

[0002] Power safety testing is a necessary test item for energy storage power supplies before they leave the factory. It mainly includes several items such as heavy object impact, compression, and needle penetration. It is mainly used to detect whether the energy storage power supply will explode or catch fire under the action of external force.

[0003] The authorized publication number "CN220820200U" describes "a safety testing device for power management, including a bottom housing, a power supply placement rack fixedly connected to the middle position of the top of the bottom housing, a puncture needle fixedly connected to the middle position of the bottom of the sliding plate, and a splash range limiting structure provided between the top of the bottom housing and the bottom of the sliding plate. This safety testing device for power management, by providing a bottom outer shell and a top inner shell, allows the puncture needle to contact the energy storage power supply and puncture downwards from the top during use. During downward puncture, the top inner shell presses down synchronously with the sliding plate and slides downwards along the inner wall of the bottom outer shell. When the power supply catches fire and explodes, the three-sided surrounding baffle formed by the bottom outer shell and the top inner shell can limit the range of the explosion splash, reducing the difficulty of subsequent cleanup and achieving the function of limiting the explosion splash range. This solves the problem that devices lack the function of limiting the explosion splash range."

[0004] The aforementioned patent can limit the range of explosion splash, reduce the difficulty of subsequent cleanup, and achieve the function of limiting the range of explosion splash. It solves the problem that the device does not have the function of limiting the range of explosion splash. However, during use, the protective cover cannot be adjusted to match the size of the power supply. At the same time, its open design cannot include the protection effect of explosion.

The synchronization component is located on the two bidirectional screws 12.

[0031] In this embodiment, the model of the lifting motor 11 can be selected from those available on the market as needed, which will not be elaborated here. The lifting motor 11 controls the rotation of the bidirectional screw 12, and the upper protective cover 4 and the lower protective cover 3 are respectively threaded to both ends of the bidirectional screw 12.

[0032] Specifically, the synchronization component includes two linkage gears 17 and a linkage belt 9. Each linkage gear 17 is fixedly connected to the top of each bidirectional screw 12, and the linkage belt 9 is sleeved on the two linkage gears 17, and the linkage belt 9 meshes with the two linkage gears 17.

[0033] In this embodiment, the two linkage gears 17 are the same size, and the two linkage gears 17 are rotated synchronously by the linkage belt 9, thereby completing the synchronous rotation of the two bidirectional screws 12.
