105results about How to "Improve clamping stability" patented technology

This utility model discloses a stable clamping clamp for wires of different diameters with parallel grooves. The clamp includes an upper clamping plate and a lower clamping plate. The lower clamping plate has first lower clamping grooves on both sides, and a raised lower clamping portion in the middle of the first lower clamping groove. The lower clamping portion has a second lower clamping groove. The upper clamping plate has a first upper clamping groove corresponding to the first lower clamping grooves, and a liftable pressure plate. Through the cooperation of the lower clamping portion and the pressure plate, the first lower clamping groove and the first upper clamping groove, and the second lower clamping groove and the second upper clamping groove, form a structure that accommodates the stranded wire and causes it to bend upwards. This increases the friction between the stranded wire and the clamping grooves. The bent stranded wire contacts both sides of the grooves, providing stable support and preventing clamp displacement. The raised inner wall of the clamping grooves enhances the contact area and friction, optimizing the structural design, reducing the risk of stranded wire detachment, and improving connection reliability and overall durability.

本实用新型涉及一种光伏桩动力头夹具及光伏桩动力头，其中，光伏桩动力头夹具包括安装筒，所述安装筒的内径大于等于光伏桩的外径，所述安装筒外侧壁沿周向至少固定设有一个底座，每个所述底座上均倾斜设有液压夹紧机构，所述安装筒外侧壁对应每个液压夹紧机构均开设开口，所述开口与安装筒内部连通，所述液压夹紧机构倾斜向下夹紧固定所述光伏桩，所述液压夹紧机构的夹紧端低于安装筒的上端面。解决了现有技术中光伏桩动力头上的液压夹紧机构通常夹紧固定光伏桩顶端，在施工过程中光伏桩顶端可能出现损坏开裂的问题。

本实用新型涉及美妆用品技术领域，提供一种假睫毛夹，包括能够沿夹持方向相互靠近的第一构件和第二构件，第一构件和第二构件的其一端部固定连接而形成固定端；第一构件包括在固定端的第一方向上的第一夹持部，第二构件包括在固定端的与第一方向不同的第二方向上的第二夹持部，第一夹持部上具有与第二夹持部相对的第一夹持面，第二夹持部上具有与第一夹持部相对的第二夹持面；第一夹持面上具有弹性材料层，弹性材料层在第一构件与第二构件沿夹持方向靠拢后与第二夹持面相贴合。本实用新型具有良好的夹持稳定性，避免误触状态下导致的假睫毛抓取错位问题。
