A power supply device for safety engineering equipment at construction sites

This invention discloses a power supply device for safety engineering equipment on construction sites, relating to the field of power supply devices. It includes a power cabinet and multiple batteries. The power cabinet is cylindrical with a notch on one side, where a side filter is installed. It should be noted that, in this embodiment, when the batteries are in use, the radial layout effectively increases the gap between batteries while ensuring the number of batteries is sufficient, increasing airflow and improving heat dissipation. A combination of central heat dissipation and rotating lateral heat dissipation ensures uniform heat dissipation for each battery, eliminating localized hotspots, improving heat dissipation efficiency, extending battery life, and reducing maintenance costs and replacement frequency. Furthermore, the sliding filter plate can slide open, directly exposing the batteries to further enhance heat dissipation. When not dissipating heat, it closes, providing ample protection against dust, moisture, and impact.

Electronic device connection cord

This utility model discloses an electronic device connector cable, comprising a connector body, a connector, and a dustproof assembly. The connector end has a plug-in portion for connecting electronic devices. The dustproof assembly includes a hollow dust cover, a spring, and a cover. One end of the dust cover is inserted into an annular groove at the connector end. An outer limiting slider slides against a limiting groove on the inner wall of the annular groove, ensuring its movement in a specific direction. A first mounting portion of the protruding outer part of the dust cover and a second mounting portion on the connector fix the spring, providing elasticity in its normal state, allowing the dust cover to protrude from the connector. The cover is detachably installed at the opening of the dust cover, covering the plug-in portion. This connector cable, through the cooperation of the dust cover and cover, effectively blocks dust and moisture from contacting the plug-in portion, avoiding poor contact caused by dust accumulation. During insertion and removal, the dust cover is compressed by external force and retracts along the limiting groove, without affecting use. After the external force disappears, it automatically resets under the action of the spring, continuously protecting the plug-in portion and preventing dust accumulation and damage.
