The invention discloses a repeatedly opened and closed anti-leakage valve with a cylindrical panel valve sealing structure. The anti-leakage valve comprises a valve body formed by combining a positioning connector, a locking cylinder and a lower connector, and a tubular mandrel a capable of moving in a reciprocating mode is arranged in the valve body and driven by an opening and closing tool to move in the reciprocating mode; a valve plate and a valve base which are matched are arranged at the position, close to the lower end, in the valve body, the valve plate is installed on a supporting base and arranged close to one side of the mandrel a, the supporting base is fixed to the inner wall of the valve body, and the valve base can move in a reciprocating mode in the axis direction of the valve body. When the anti-leakage valve is opened, the mandrel a moves downwards, the valve base is pushed to move downwards through a transmission mechanism, and when continuing to move downwards to make contact with the valve plate, the mandrel a pushes the valve plate to rotate in the side direction so that the anti-leakage valve can be opened; when the anti-leakage valve is closed, the mandrel a moves upwards, the valve plate is automatically reset under the action of a reset spring, and the mandrel a continues to move upwards and drives the valve base through the transmission mechanism to move upwards to press the valve plate in an abutting-against mode so that the anti-leakage valve is closed. The contact faces of the valve plate and the valve base are cylindrical surfaces.

The invention discloses a bending die for producing an electric box. The bending die comprises an upper bending module and a lower bending module. A sliding block pedestal is arranged at the bottom of an upper die base. Bending sliding blocks are correspondingly arranged on the left side and the right side of the sliding block base. The bending sliding blocks are connected with the upper die base through locating rods. A plurality of sliding chutes are formed in the outer wall on each of the left side and the right side of the sliding block pedestal. Sliding rails are arranged on the outer walls of surfaces, in contact with the sliding block pedestal, of the bending sliding blocks. The sliding block pedestal is connected with the bending sliding blocks through the sliding chutes and the sliding rails. The lower bending module comprises a lower die base and a lower die pedestal, which are arranged in sequence from top to bottom. The bending die is simple in integral structure, and is reasonable in design; the bending sliding blocks are connected with the sliding block pedestal in a sliding manner, and after the four sides of the electric box are bent, a tool can be withdrawn smoothly, in this like, the four sides of the electric box are bent synchronously by using one die, so that the production cost is reduced greatly, the production efficiency is improved, and the product quality is more stable.

When optical disk is placed to tray, first functional force is applied to tray optical drive to overcome a lesser magnetic attraction, when optical disk is not placed to tray, second functional force is applied to tray optical drive to overcome a larger magnetic attraction. Maximum of second functional force is larger than maximum of first functional force.
