This utility model relates to the field of relay technology, and provides an anti-arc safety relay for charging piles, including a relay housing and a coil installed at the center of the bottom of the housing; an iron core, which is slidably inserted into a through hole running vertically through the center of the coil; a transmission column, which is installed at the top of the iron core; a moving contact assembly, which is installed at the top of the transmission column; and two arc-extinguishing components, which are symmetrically installed on the left and right side walls near the top of the relay housing. This anti-arc safety relay for charging piles, through the scientific layout of multi-layer arc-extinguishing grids, a fast-rebound disconnection mechanism, and a buffer reset design, can effectively suppress and quickly eliminate the arc generated between the moving and stationary contacts, significantly improving the safety performance and service life of the relay.

The utility model discloses a high accuracy, prevent dead vertical motion platform, include: vertical left side motion mechanism and right side motion module and the beam of cross arrangement in left side motion mechanism and right side motion module on, left side motion mechanism and right side motion module are provided with first bearing and second bearing respectively for supporting the both ends of beam, and at least one end on the beam is provided with the waist groove that can with first bearing and / or second bearing relative horizontal sliding. Adopt left side motion mechanism and right side motion module synchronous drive beam lifting and realize high accuracy motion, through setting first bearing and second bearing connection beam and left side motion mechanism and right side motion module, and setting waist groove on the beam realizes the relative displacement between first bearing or second bearing, thereby prevent when left side motion mechanism and right side motion module appear synchronous deviation, utilize first bearing or second bearing in waist groove and move and prevent motion dead lock, thereby ensure the precision and stable of beam movement.

This utility model relates to the field of capacitive touchscreen technology and discloses a hot-pressing device for producing capacitive touchscreens. It includes a processing box, with first electric slide rails fixedly connected to the left and right sides of the top of the processing box. First sliding blocks are slidably connected to the outer walls of the first electric slide rails. A support column is fixedly connected to the top of the first sliding block, and a horizontal plate is fixedly connected to the top of the support column. A second electric slide rail is fixedly connected to the bottom of the horizontal plate, and a second sliding block is fixedly connected to the bottom of the second electric slide rail. In this utility model, a bidirectional motor drives a lead screw to rotate, causing a clamping plate to move and clamp the capacitive touchscreen. A cylinder pushes a push plate and a recessed box to descend. The sliding column inside the recessed box, under the action of a damping spring, causes the heating plate to slowly and stably approach the capacitive touchscreen. The damping spring also acts as a buffer, preventing the heating plate from applying excessive pressure to the capacitive touchscreen and causing damage. This ensures the stability and precision of the hot-pressing process and improves product quality.

This utility model relates to the technical field of automotive chassis components and discloses a crossbeam tie rod welding assembly, including a crossbeam, a left tie rod assembly, a right tie rod assembly, a locating pin, and a middle connecting seat. The crossbeam is a long, rigid structure that serves as a basic load-bearing component, connecting the left and right tie rod assemblies and providing a support frame for the entire assembly. It can distribute and transmit longitudinal and lateral forces during vehicle operation. High-strength steel is used to ensure structural strength and rigidity. This utility model achieves precise pre-positioning through the locating pin, combined with a full welding process, ensuring accurate connection positions and connection strength of each component. It solves the problems of poor assembly compatibility and uneven connection strength, making force transmission more stable and effectively resisting vibration and impact during vehicle operation.
