The utility model discloses a handheld vacuum suction device, which comprises a handle and arranged on both ends of the handle and perpendicular to the axis of the handle and two chuck assembly, the handle is arranged inside the connecting rod and a rear connecting rod are connected with each other, wherein the front rod front and back connecting rod are respectively arranged respectively before and after the end of two chuck assembly U groove interaction, chuck assembly comprises a sucker, cylinder, piston, a return spring, wherein the sucker is connected with a cylinder body, a piston arranged in the cylinder body, the piston is arranged at the rear end of the return spring, the piston return spring and a through hole through the open ends of the handle, and through the U slot through the through hole in the handle before and after the opening of the connecting rod. The utility model relates to a hand-held vacuum suction device, wherein the air in the suction chamber is extruded when the upper and the lower surfaces of the absorbed workpiece face are pressed down, and negative pressure is formed when the suction chamber is lifted. The device does not need to increase the pumping unit, and does not increase the superfluous switching action during adsorption and release. Save energy for energy saving and environmental protection products.
【技术实现步骤摘要】
【专利摘要】本技术公开了掌上型真空吸具,包括手柄以及设置在手柄两端并垂直于手柄中轴线的前后两个吸盘总成,所述手柄内部设置有相互连接的前连杆和后连杆,所述前连杆前端和后连杆后端均开设有分别与前后两吸盘总成相互作用的U型槽,吸盘总成包括吸盘、缸体、活塞、回位弹簧,所述吸盘与缸体连接,缸体内设置活塞,活塞后端设置回位弹簧,所述活塞及回位弹簧穿过手柄两端开设的通孔,并且在穿过通孔时经过手柄内的前、后连杆所开设的U型槽。本技术手持真空吸具在被吸取的工件面上下压时,吸盘腔内的空气被挤压出去,再提起时形成负压。这种装置不需要增加抽气动力装置,不会增加在吸附和放下时的多余开关动作。节省能源,为节能环保产品。【专利说明】掌上型真空吸具
本技术涉及吸具,具体地说是一种掌上型真空吸具。
技术介绍
常用的形成负压的方法为:真空泵和真空发生器。真空泵是吸入口形成负压,排气口直接通大气,两端压力比很大的抽除气体的机械。真空发生器的工作原理(柏努利原理)是利用喷管高速喷射压缩空气,在喷管出口形成射流,产生卷吸流动力。这两种方法都需要有动力源,在实际使用中存在诸多不便。尤其在手动工具上, ...
