在管道安装中,一般用龙门钳夹紧以便加工螺纹。而龙门钳体积大,笨重、夹紧速度慢、搬运不方便。为克服以上缺点试制了一种新型夹管工具——夹管器。主要是利用杠杆的齿锁方式来代替龙门钳的螺杠压紧方式。如附图所示,由底座1、压杆2、挂钩3、手把4、拉杆5活动钢销6、上夹口7、下夹口8、弹簧9组成固定于工作台上。上夹口杠杆压力的传递方式是由压力F_1将力传递给F_2,经F_3至F_4。经几个杠杆力的作用后,F_4的压力是F_1的好几倍。开启时将手把4向上提升,同时将挂钩
In the pipeline installation, the general use of gantry clamp in order to process the thread. The gantry pliers, bulky, bulky, slow clamping, handling inconvenient. In order to overcome the above shortcomings trial of a new type of pinch - the pinch. Mainly use the lever to lock the way instead of the gantry pliers screw compression. As shown in the drawings, the base 1, the press rod 2, the hook 3, the handle 4, the rod 5, the movable steel pin 6, the upper clamp port 7, the lower clamp port 8 and the spring 9 are fixed on the worktable. The pressure on the clamping lever is transmitted by the pressure F_1 to F_2 and F_3 to F_4. After several leverage the role of F_4 pressure is several times F_1. When open, lift the handlebar 4 upwards while hooking
