Referring to fig. 1-7, the present invention provides a technical solution: a clutch speed reducing mechanism based on manual-automatic integration comprises a shell 3 and a top cover 1 installed on the shell 3, wherein an external knob mechanism 2 is fixedly installed outside the shell 3, a first-stage shaft 4, a second-stage shaft 5, a third-stage shaft 6, a fourth-stage shaft 7, a fifth-stage shaft 28 and a sixth-stage shaft 10 are arranged inside the shell 2, a first-stage gear set 21 is arranged on the first-stage shaft 4, a second-stage shaft 5 is fixedly installed on the second-stage shaft 20, a third-stage gear set 19 is fixedly installed on the third-stage shaft 6, a fourth-stage gear set 18 and a shaft sleeve 8 are fixedly installed on the fourth-stage shaft 7, an upper bearing 9, a fifth-stage gear set 16 and a lower bearing 17 are fixedly installed on the fifth-stage shaft 28, and a claw disc gear 11, a shifting;
the external knob mechanism 2 comprises a rectangular frame 27 fixedly installed outside the shell 3, a hinge 24 is arranged in the rectangular frame 27, the hinge 24 is fixedly connected with a knob 26 through a pin shaft 25, and the knob 26 is movably connected with the shifting rod 12.
It is noted that the first gear set 21 is meshed with the second gear set 20, the second gear set 20 is meshed with the third gear set 19, the third gear set 19 is meshed with the fourth gear set 18, the fourth gear set 18 is meshed with the fifth gear set 16, and the fifth gear set 16 is movably meshed with the claw disk gear 11.
It is worth noting that a clutch handle 23 and a gland 22 are further mounted on the housing 3, and one end of the clutch handle 23 is fixedly connected with the sixth-stage shaft 10.
It is noted that the upper bearing 9 has a diameter of 4mm in particular and the lower bearing 17 has a diameter of 5mm in particular.
It is to be noted that the dog plate 13 is rotated coaxially with the sixth-stage shaft 10 by a pin key.
It is worth noting that the speed reducing shell and the external knob mechanism 2 are respectively fixed on the inner wall and the outer side wall of the window frame through four threaded holes at the bottom and the side edges; in fig. 2, each set of gears is coaxially matched with a corresponding shaft, and the teeth are meshed with each other, wherein a 4mm upper bearing 9 and a 5mm lower bearing 17 are coaxially matched at two ends of a five-stage gear set 16, and a copper sleeve 15, a spring 14 and a claw disc 13 are coaxially matched with a six-stage shaft 10; the shifting rod 12 is fixed on the shell of the reduction box through a hole on the shifting rod, the shifting rod is positioned between the claw disk gear 11 and the claw disk 12, the claw disk 12 coaxially rotates with the six-stage shaft 10 through a pin key, the claw disk gear 11 does not synchronously rotate with the six-stage shaft 10, and the movement of the claw disk gear 11 and the six-stage shaft is not related; the gland 22 is fixed on the outer wall of the reduction box shell by screws, a pin shaft inserted in the deflector rod is pressed downwards to ensure that the deflector rod 12 is axially fixed and can rotate around a shaft, the clutch handle is inserted on the reduction box shell, and the conical surface of the clutch handle is always in surface contact with one end of the deflector rod 12; the hinge 24 pin shaft is inserted in the hinge hole and the elliptical groove hole of the knob, the bottom of the knob is provided with an inner hexagonal groove which is matched with an outer hexagonal of the clutch handle
Example (b):
the device is arranged at the bottom edge of a window frame, a push rod for controlling the opening and closing of a window is matched and arranged with an outer hexagonal at one end of a six-stage shaft, and the six-stage shaft rotates along with the rotation of the push rod to realize the actions of opening and closing the window. The motor is arranged at the end of the first-stage gear set, under the condition of normal power supply, the motor outputs power to rotate forward and backward to drive each gear set inside, the claw disc gear rotates along with the claw disc gear, at the moment, the claw disc gear is meshed with the claw disc, and the claw disc and the six-stage shaft rotate synchronously, so that the six-stage shaft rotates to drive the push rod to open and close the window, and the process of opening and closing the window is electrically operated. When the motor stops supplying power (power failure state), because the motor needs to output larger torque, a plurality of gear sets are needed to reduce the speed and lift the torque in the middle, therefore, when the window is manually pushed and closed in the power failure, the meshing between the gear teeth inside the window ensures that the end of the push rod cannot rotate the six-stage shaft, the push rod cannot rotate, the window cannot be manually opened and closed, at the moment, the clutch handle is driven to rotate through the rotation of an external hinge, the middle part of the clutch handle is a special-shaped frustum cone, the conical surface pushes one end of the shifting rod in the rotating process, the shifting rod rotates around a shaft, the end face of the bottom of the shifting rod pushes the claw disc to be separated from the claw disc gear, the claw disc and the six-stage shaft rotate independently of the claw disc gear and the front several-stage gear, the six-stage shaft can rotate independently and freely, the push rod can also rotate independently and freely at the moment, and therefore the window is opened and closed manually and easily and continuously at the moment, and the window opening and closing process is a manual window. If the electric power is recovered, the hinge is rotated, the claw disc is meshed with the claw disc gear again under the action of the pressure of the spring, and the motor drives the six-stage shaft to drive the push rod to rotate so as to realize the action of opening and closing the window.
Although embodiments of the present invention have been shown and described, it will be appreciated by those skilled in the art that changes, modifications, substitutions and alterations can be made in these embodiments without departing from the principles and spirit of the invention, the scope of which is defined in the appended claims and their equivalents.
