I designed an elastic ring tap protection device for tapping parts on the machine. It has more advantages than the shear protection device, the steel ball spring, the protection device and the friction protection device, and the effect is good after being used on site. Now introduced as follows. The structure of the tap protection device is shown in the figure. It consists of a tap 1, a bushing 2, an elastic ring 3, a bolt 4, a V-shaped block 5, a spring 6 and a taper sleeve 7. The bolt 4 is screwed to the elastic ring 3, and pushes the V-shaped block 5 to firmly grip the tail square portion of the tap 1. The bushing 2 is used on the one hand to accurately position the tap; on the other hand it can be replaced to accommodate different sizes of taps. The tap protection device utilizes the large elastic deformation force of the elastic ring 3
Flexible lift gate is a flexible soft curtain door, inside and outside the two curtains, curtains used between the aluminum beams connected with a vertically movable rail, the roof beams have levels not in the same straight line and hangar large plants in particular be applicable. Flexible lift door installation does not take up interior space in the hole inside. When the fiest move to open the door, and finally superimposed over the hole.
