The invention discloses a well lid for emergency drainage. The well lid comprises a well lid supporting base, a lid plate and a plurality of windows, wherein the lid plate is matched with the well lid supporting base for forming a well lid; the windows are formed on the well lid supporting base; the lid plate comprises rotating plates which are the same as the windows in shape and quantity; the rotating plates are rotatably connected with the windows through connection shafts; the well lid further comprises a rotation piece and a transmission piece; the rotation piece is connected with the well lid supporting base and can rotate forwards and backwards; and the transmission piece is arranged between the rotation piece and the rotating plates, and is used for converting the rotation of the rotation piece into a force to drive the rotating plates to rotate forwards and backwards around the connection shaft, so as to open and close the windows. According to the well lid provided by the invention, the rotating plates rotate forwards and are entirely opened under the effect of the rotation piece and the transmission piece, drainage is fast performed, and emergency drainage is realized. In the drainage process, as long as the rotation piece is not rotated, the windows keep an opened state all along, so as to avoid blocking of drainage openings. After the drainage is finished, the rotation piece is reversely rotated so that the rotation piece is reversely closed under the driving of the transmission piece.

The invention discloses an electronic device shell which comprises a first shell, a second shell, an elastic part and a slider. A first hook is arranged on the inner side of the first shell, the inner side of the first shell is matched with the second shell, a jack is arranged on the second shell, the slider is mounted on the second shell and can move along the direction of the jack, a first slider opening is arranged on the slider and matched with the first hook, the elastic part contacts with the slider and applies elastic force facing the jack to the slider, the first hook can extend into the first slider opening and is fastened with the slider, the slider applies first tension facing the slider to the first hook, and the second shell applies second tension to the slider, wherein the direction of the second tension is as same as that of the first tension. The first shell of the electronic device shell can be conveniently fastened on the second shell, and the first shell and the second shell can be conveniently unfastened.

A thermal tripping mechanism of a surge protection device comprises an elastic mechanism. Two first protection components (103) and one second protection component (108) form a Y-shaped layout and the two first protection components (103) are directly or indirectly connected to the second protection component (108) by using a thermal fusing material. The elastic mechanism comprises an elastic part (105) and a slide part (106). The elastic part (105) drives the slide part (106) to move by an elastic force. When the two first protection components (103) are both in a normal working state, the thermal fusing material does not reach a fusing temperature, the two first protection components (103) and the second protection component (108) form a conductive path, and the elastic part (105) is in an energy storage state. When at least one of the first protection components (103) is in an abnormal working state, the thermal fusing material reaches the fusing temperature and is fused, the elastic part (105) releases energy for driving the slide part (106) to move, and the slide part (106) moves to cut off the conductive path.
