Detailed Description
The present invention will be described in detail with reference to the embodiments shown in the drawings, but it should be understood that these embodiments are not intended to limit the present invention, and that the functional equivalents, methods, or structural equivalents thereof, or substitutions thereof by those skilled in the art are all within the scope of the present invention.
Referring to fig. 1 to 3, the present embodiment provides a manual closing mechanism for a plastic housing, including an inner hexagonal connector 10, a large gear 20, a small gear 30, a rack 40, a first fixing frame 50a, a second fixing frame 50b, and a fixing screw 60, where the inner hexagonal connector 10 is fixedly connected to the large gear 20, the large gear 20 is connected to the small gear 30, and the small gear 30 is connected to the rack 40. The first and second fixing frames 50a and 50b are connected to the pinion 30 and the rack 40, and the fixing screw 60 connects the rack 40 to the operating mechanism handle 70 of the circuit breaker.
The rack 40 has a hole in its upper end for receiving the fixing screw 60, and when the rack 40 moves up and down, the fixing screw 60 and the breaker mechanism 70 move up and down.
The rack 40 has a square hole group in the side to be engaged with the pinion 30. The pinion 30 is connected to the rack 40, and the circular motion of the pinion 30 can be converted into the reciprocating linear motion of the rack 40 by engaging with the rack 40 when the pinion 30 rotates.
The rack 40 has a first fixing frame 50a and a second fixing frame 50b with fixed racks above and below, the first fixing frame 50a and the second fixing frame 50b can accommodate the pinion 30 and the rack 40, and the first fixing frame 50a and the second fixing frame 50b are connected by rivets or screws.
The big gear 20 is fixedly connected with the inner hexagonal connecting piece 10, and the big gear 20 is meshed with the small gear 30.
The working principle of the manual closing mechanism is as follows:
as shown in fig. 2, when manual closing is required, a hexagonal wrench is used to rotate the inner hexagonal connector 10 clockwise, the rack 40 moves upward due to the meshing transmission of the large gear 20 and the small gear 30, and the rack 40 drives the operating mechanism handle 70 of the circuit breaker to move upward, so that the circuit breaker is closed. When the brake is opened, the hexagon socket head cap connector 10 is rotated anticlockwise by a hexagon wrench, the rack 40 moves downwards under the transmission of the large gear 20 and the small gear 30, and the rack 40 drives the operating mechanism handle 70 of the circuit breaker to move downwards so as to open the brake.
The manual switching-on mechanism adopts a gear transmission mode to perform manual switching-on, is convenient and quick to install, has few parts, is stable and efficient, and is labor-saving to operate.
It is obvious to a person skilled in the art that the invention is not restricted to details of the above-described exemplary embodiments, but that it can be implemented in other specific forms without departing from the spirit or essential characteristics of the invention. The present embodiments are therefore to be considered in all respects as illustrative and not restrictive, the scope of the invention being indicated by the appended claims rather than by the foregoing description, and all changes which come within the meaning and range of equivalency of the claims are therefore intended to be embraced therein.
