The invention provides height-adjustable installation equipment for a concealed power distribution terminal box. The height-adjustable installation equipment comprises an upper supporting plate, a lower supporting plate, a sliding groove, a sliding block, a positioning screw, a fixed piece, a small-size motor, a terminal box installing plate, a nut seat, a screw rod and a power supply, wherein the sliding groove is assembled in the middle position of the front end surface of the lower supporting plate; the upper end of the sliding block is connected with the upper supporting plate, and the lower end of the sliding block is assembled in the sliding groove; the fixed piece is arranged on the right end surface of the upper supporting plate; the positioning screw penetrates through the fixed piece to be assembled in the sliding groove; the small-size motor is arranged on the upper end surface of the upper supporting plate; a groove body is arranged in the middle position of the front end surface of the upper supporting plate; the screw is arranged in the groove body; the power supply is arranged on the rear end surface of the upper supporting plate; the nut seat is assembled on the screw rod; and the terminal box installing plate is fixed on the front end surface of the nut seat. The height-adjustable installation equipment provided by the invention has the advantages that the structure is simple, the process is reasonable, a fast and accurate height-adjusting function is achieved, the application range is expanded, and the safe and reliable effects are achieved.

The invention discloses a touch-control type safe socket which comprises a shell body and a power line. Slots which are used for enabling a zero line plug foot of a plug and a live wire plug foot of the plug to be inserted are formed in the shell body. Inner conducting strips and outer conducting strips are arranged beside the slots. The inner conducting strips are arranged between the outer conducting strips and the slots. The outer conducting strips are connected with the power line. The shell body is further provided with a touch-control type isolation device which is controlled by the plug connected with the touch-control type safe socket in an inserted mode and capable of blocking communication of the outer conducting strips and the inner conducting strips. The touch-control type safe socket has the advantages of being capable of greatly increasing safety of products, reliable in operation and capable of saving conducting materials.

The invention relates to the field of low-voltage electrical appliances, in particular to a miniature circuit breaker including a button mechanism, a circuit breaker casing and an anti-closing mechanism. The button mechanism is disposed at one end of the circuit breaker casing and is in sliding fit with the circuit breaker casing. The anti-closing mechanism comprises a first locking member pivotally disposed on the circuit breaker casing. One end of the first locking member is in locking fit with the button mechanism to block the button mechanism from moving in the closing direction. After theminiature circuit breaker is assembled to the circuit breaker assembly position in place, the casing at the circuit breaker assembly position acts on the first locking member so that the button mechanism can move in the closing direction to perform the closing operation after the first locking member is released from the locking fit with the button mechanism. The anti-closing mechanism of the miniature circuit breaker ensures that the miniature circuit breaker can be closed only after assembled to the circuit breaker assembly position and assembled in place, so that the use safety is ensured.
