Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a locking function's switch door gear, its includes that main part 1 and activity hinge joint install trigger 2 on it, is provided with storage tank 3 in the main part 1, installs 4 pull rod one ends of pull rod 4 in the storage tank 3 and 2 activity hinge joints of trigger, the other end through 6 movable storage tank 3 of arranging in of uide pin, storage tank 3 in still be provided with extension spring 7, extension spring 7 one end is connected with pull rod 4, the other end is connected its characterized in that with main part 1: the main body 1 is also internally provided with a guide wheel frame 8, one end of the guide wheel frame 8 is provided with a guide wheel 81 which is contacted with the outer contour of the trigger 2, the other end of the guide wheel frame 8 is connected with an electric mechanism, and the electric mechanism pushes the guide wheel frame 8 to move.
The outer contour of the trigger 2 is provided with an inward-recessed locking groove 21, and after the door closing device is closed, the electric mechanism pushes the guide wheel 81 to be clamped in the locking groove 21.
The electric mechanism comprises a screw 91 driven by a speed reducing motor 9, the screw 91 is in threaded connection with a nut 92 on the guide wheel frame, and when the screw 91 rotates, the guide wheel frame 8 is pushed to move.
The accommodating groove 3 is also fixedly provided with a connecting plate 31, and the electric mechanism is fixed in the connecting plate 31.
The guide wheel 81 is installed on the guide wheel frame 8 through a guide wheel shaft 82, and two ends of the guide wheel shaft 82 extend outwards and are placed in guide wheel grooves 83 on the main body 1 to slide.
The working principle is as follows: when the door needs to be opened, the trigger rotates around the rotating shaft of the main body, so that the door is opened and closed. In the door opening process, the position between the trigger and the main body is changed, and the trigger stretches the tension spring 7 through the pull strip to generate reset power. When the door needs to be closed, the main body and the trigger are pulled by the pulling force of the tension spring 7 to generate angle change, so that the automatic door closing reset function is achieved.
When the door closing mechanism is closed, the screw 91 driven by the speed reducing motor 9 rotates, the screw 91 is in threaded connection with the nut on the guide wheel frame, and when the screw 91 rotates, the guide wheel frame 8 is pushed to move towards the trigger 2, so that the guide wheel on the guide wheel frame is forced to be buckled into the locking groove on the trigger, and the locking effect on the trigger is achieved. When the unlocking is needed, the control system controls the speed reducing motor to rotate reversely, and the guide wheel frame is pulled by the screw rod, so that the guide wheel is separated from the locking groove.
