The invention relates to a B type intelligent circuit breaker with automatic switching-in function, which comprises a circuit breaker body, wherein the circuit breaker body comprises an upper cover, a handle, a bottom box and a bearing plate, wherein the upper cover is provided with a notch, two ends of which correspond to the opening / closing positions of the circuit breaker; the handle extends out of the notch; the bottom box is provided with a circuit breaker actuating mechanism, an incoming line terminal and an outgoing line terminal, and the circuit breaker actuating mechanism is triggered by the handle; the bearing plate is arranged between the upper cover and the bottom box, and is provided with a pinion and rack mechanism and a pushing part, and the pushing part is connected with the handle; and the bottom box is internally provided with a motor which is controlled by an automatic switching-in control unit, and the pinion and rack mechanism converts the rotation of the motor into the reciprocating motion of the pushing part, so that the handle is shifted between the opening / closing states.

The invention relates to a mechanical device, namely a sunshading umbrella. The sunshading umbrella is characterized in that a screw rod (2) capable of carrying out positive and negative bidirectional rotation under the driving of a motor is mounted on a bottom plate (1); the screw rod (2) is externally sleeved with an inner sleeve (3); the inner sleeve (3) is externally sleeved with an outer sleeve (4); the upper end of the inner sleeve (3) is connected with an umbrella cover (5); a lower opening of the umbrella cover (5) is opposite to the bottom plate (1); the outer side of the outer sleeve (4) is connected with a folding umbrella surface (8); the inner sleeve (3) is provided with an anti-rotation component; the inner sleeve (3) positively rotates with the screw rod (2) and lifts to the upper part of the screw rod (2) to be separated from the anti-rotation component and to be in rigid connection with the screw rod (2) and the outer sleeve (4), and the inner sleeve (3), the screw rod (2) and the outer sleeve (4) carry out synchronous positive rotation to allow the umbrella surface (8) to be unfolded; and when the screw rod (2) rotates negatively, the outer sleeve (4) rotates negatively to fold the umbrella surface (8), and the inner sleeve (3) moves downwards to close the umbrella cover (5). The sunshading umbrella has the benefits that the sunshading umbrella is arranged at the roof of an automobile, the umbrella surface is folded at ordinary time, and is unfolded to cover an automobile body, shield sun and protect the automobile during parking; and the sunshading umbrella can also act as a sunshade for other places, is simple in structure and flexible and reliable in operation, and is light and suitable for remote control, so that the sunshading umbrella has good market prospects.

The invention discloses an intelligent microscope objective table elevating mechanism and an intelligent microscope composed by same; the intelligent microscope objective table elevating mechanism comprises an objective table mechanism, an electric mechanism and a handwheel mechanism; the objective table mechanism comprises an objective table, an objective table support, an objective table slide block and a main frame; the electric mechanism comprises a tooth bar, a first gear, a motor frame, a motor frame connecting block and a motor; the objective table is arranged on the objective table support; the objective table support is arranged in the front end of the main frame, and movably connected with the main frame up and down through the objective table slide block. The novel full automatic operation structure is designed, and a manual operation function is compatible, so original microscope frame structure characteristics are not changed; a user can either use the manual operation mode or use the full automatic operation mode.

The invention discloses a built-in C-type intelligent circuit breaker with an automatic switching-on function, which comprises a box body and a load bearing plate, wherein the inside of the box body is provided with a circuit breaker action mechanism, a line incoming end and a line outgoing end; the circuit breaker action mechanism is triggered by a poke rod positioned in the box body; the load bearing plate is positioned in the box body and is provided with a translational motion mechanism and a poking part; the poking part and the poke rod are abutted; under the control of an automatic switching-on control unit, the poking part is pushed by the translational motion mechanism to carry out reciprocating action, so as to enable the poke rod to trigger the circuit breaker action mechanism to switch on and off the circuit breaker; the stirring part is a shifting fork; one end of the shifting fork is provided with a poking hole; the poke rod is arranged in the poking hole; two wings of the shifting fork are respectively provided with connection holes; and the middle part of the shifting fork is coupled with the load bearing plate.
