This invention provides an educational toy and its interactive system, relating to the toy industry. The invention includes a base plate and a rubber pad. The rubber pad has multiple grooves on its top, and the base plate has multiple square slots on its top. A short tube is provided on one side of each of the square slots. Inside each short tube are a sliding block, a support spring, and a telescopic airbag. An air guide tube is provided on one side of the base plate. The invention controls a solenoid valve to open, allowing gas inside the telescopic airbag to escape through the long tube, air guide tube, and solenoid valve. The elastically deformed telescopic airbag returns to its original shape, and simultaneously, the rebounding support spring pulls the sliding block. This resets the sliding block away from the mounting tube, removing the indicator block's limiting position. The indicator block can be quickly replaced as needed, ensuring that it can be changed according to the user's educational purpose for children.

This utility model discloses a detection mechanism for limiting the loading device of a dry quenching coke, including a track support and a trolley track. This utility model employs mechanical mechanisms such as a limit sensing base plate and a track limit switch. In actual use, the entire device is installed at the furnace opening of the dry quenching furnace. The limit support is welded to the base below the trolley track where the rear wheels of the loading trolley are located when the furnace cover is fully open. During subsequent operations, the loading trolley can be pushed by an electro-hydraulic actuator, causing it to move along the trolley track. The track limit detection device of this utility model is installed on the trolley track, providing direct feedback on the actual position of the furnace cover opening. Furthermore, the track limit switch uses magnetic induction to limit the loading device via the limit sensing base plate on the trolley, combining with the stroke limit of the electro-hydraulic actuator to achieve double insurance for limiting the loading device of the dry quenching coke, completely preventing accidents caused by the hoist misjudging the opening position of the loading device.

The utility model discloses an automobile handle shell stamping die, which relates to the field of automobile part processing, and comprises a base and a mounting cover, the upper end of the base is internally provided with a sliding groove, one side of the bottom of the base is rotatably provided with a rotating rod, and one end of the rotating rod is fixedly provided with a second rotating plate; a first threaded rod is fixedly mounted at the other end of the rotating rod, a lower mold is in threaded connection with the outer ring of the first threaded rod, the lower mold is slidably mounted in the sliding groove, the mounting cover is arranged at the upper end of the base, and second inner threaded grooves are formed in the two sides of the interior of the mounting cover correspondingly; a second threaded rod is in threaded connection with the interior of the second inner threaded groove, and a first rotating plate is fixedly mounted at one end of the second threaded rod. Due to the adoption of the structure, the accuracy of a stamping position is ensured, and the effect of detaching the lower die can be effectively realized, so that the replacement and maintenance of the lower die are ensured.

The utility model relates to a strip-shaped plastic cooling and air-drying device which comprises a supporting frame and a cooling tank arranged on the supporting frame, the bottom of the cooling tank is provided with a downwards-concave water flowing tank, the water flowing tank is obliquely and downwards arranged, a pressing roller is arranged in the water flowing tank and can press extruded plastic strips into the water flowing tank, and a water flowing pipe is arranged at the upper end of the water flowing tank; a circulating water pump is arranged at the lower end of the water flowing groove and connected with the water flowing pipe, a guide-in roller and a guide-out roller are arranged on the upper portions of the two ends of the cooling groove respectively, a draught fan is arranged on the side face of the guide-out roller, an arc-shaped air guide plate is arranged below the draught fan, and the arc-shaped air guide plate is located below the plastic strips and obliquely faces the guide-out roller.
