The invention relates to an anti-explosion keyboard, in particular to an anti-seepage, anti-deformation and anti-explosion keyboard which comprises a housing, a cover plate is arranged at an opening in the lower end of the housing, a circuit board is arranged in the housing, keys are further arranged on the housing and matched with the circuit board, a surface anti-seepage device is arranged outside the housing, and through the surface anti-seepage device, water and dust can be prevented from entering gaps between the keys and the cover shell from the upper surface, a good sealing effect is further achieved, a key anti-seepage device is arranged between the cover shell and the keys, a gap anti-seepage device is arranged between the cover shell and the cover plate, waterproof blocking can be formed, meanwhile, the deformation resistance strength of the edge of the cover plate can be improved, the protruding edges can form positioning in the installation process, then it is guaranteed that the cover plate and the cover shell are right opposite in position, an anti-seepage supporting device is arranged at the lower end of the cover plate, the keyboard can be separated from the platform, then water can be prevented from entering the cover shell from a gap between the cover plate and the cover shell, and the anti-seepage purpose is achieved.

The invention discloses a lead frame die switching device, a main body seat, a sliding plate is slidably connected on the upper surface of the main body seat, three molds are detachably connected on the upper surface of the sliding plate, and a punching plate is arranged on the upper surface of the main body seat The main body seat is provided with a quick switching mechanism; the quick switching mechanism includes a sliding groove opened in the main body seat, and a sliding block is slidably connected in the sliding groove, and the sliding block is connected to the lower surface of the sliding plate. Fixed connection, two sliding sleeves are fixedly connected through the main body seat, and connecting blocks are sealed and slidably connected in the sliding sleeve, and the two connecting blocks are respectively fixedly connected with the two side walls opposite to the slider. The advantages are: the switching device of the present invention can quickly switch the mold in the continuous high-speed stamping process, thereby improving the processing efficiency, and the position of the mold after switching is accurate, ensuring the processing quality, and at the same time, it can buffer part of the stamping process. impulse, protective device.

The invention relates to an easy-to-use cooking utensil, which comprises a body, an inner pot with a cooking cavity and a detachably connected inner cover, the inner cover includes a frame body, a sealing ring and a metal cover body, and the frame body is compressed and sealed ring to fix it on the outer periphery of the metal cover, and the frame body extends outward to form a convex portion, and the convex portion is provided with a steam valve, and the steam valve includes an air inlet and an exhaust port, and the air inlet It is arranged on the metal cover body, and the exhaust port is arranged on the convex part facing downward. Adopting this technical solution, the steam valve and the inner cover can be disassembled and cleaned as a whole, which can avoid the problem that many cleaning parts may cause missing installation; The condensed water can be discharged directly through the exhaust port of the steam valve, preventing the condensed water from accumulating in the steam valve or flowing back into the cooking cavity and affecting food hygiene.
