Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides a child locks switching door gear of function, 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 pull rod 4 in the storage tank 3, pull rod 4 and trigger 2 activity hinge joint, storage tank 3 in still be provided with extension spring 7, extension spring 7 is connected its characterized in that with pull rod 4: the main body 1 is also internally provided with a guide wheel frame 8 with a spring 95, 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, and the electric mechanism pushes the guide wheel frame 8 to move through the spring 95.
The outer contour of the trigger 2 is provided with an inward-concave locking groove 21, and the electric mechanism pushes the guide wheel 81 to be clamped in the locking groove 21 through a spring 95.
The electric mechanism comprises a screw 91 driven by a speed reducing motor 9, the screw 91 is in threaded connection with a nut 94 on a pressure plate 93, and when the screw 91 rotates, the pressure plate 93 is pushed to force a spring 95 to compress, so that the guide wheel frame 8 moves relatively.
The spring 95 is sleeved on the surface of the guide wheel frame 8, one end of the spring is pressed against the pressing plate 93, and the other end of the spring is pressed against the guide wheel seat 84 of the guide wheel frame.
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 seat 84 through the guide wheel shaft 85, and both ends of the guide wheel shaft 85 extend outwards and are placed in the guide wheel groove 86 on the main body 1 to slide.
The end surface of the pressing plate 93 is provided with a guide hole 82, and one end of the guide wheel frame 8 is arranged in the guide hole 82.
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 and the pull rod 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.
After the door closing mechanism is closed, the screw rod 91 driven by the speed reducing motor 9 rotates, the screw rod 91 is in threaded connection with the nut 94 on the pressing plate 93, when the screw rod 91 rotates, the pressing plate 93 is pushed to force the spring 95 to compress, so that the guide wheel frame 8 moves relatively, the spring 95 pushes the guide wheel frame 8 to move towards the trigger 2, and a guide wheel on the guide wheel frame is forced to be buckled into a locking groove on the trigger, so that the locking effect on the trigger is achieved. The spring has a certain compression stroke, so that the requirement on the movement stroke precision of the guide wheel frame can be reduced, the problem that the locking effect of the speed reducing motor is poor due to the over-small stroke is avoided, the deformation of related parts caused by the hard extrusion of the guide wheel and the locking groove due to the over-large stroke of the speed reducing motor is avoided, and even the damage of the speed reducing motor is avoided. 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.
On the other hand, some products need to realize the secondary locking function to the door body, can continue to realize the secondary locking function to trigger direction secondary motion through electric mechanism.
Compared with the prior art, the door closing device in the present case can be automatically locked when closing the door, thereby effectively guaranteeing the sealing performance of the door when products such as an oven, a microwave oven, a refrigerator and the like which are applied to the door are used and need the door, also avoiding the misoperation of users such as children and the like to open the door, guaranteeing the use safety of equipment, meeting the requirements of different products (the size error of the product part), and highlighting the automation and being widely popularized and used.
The basic principles and the main features of the invention and the advantages of the invention have been shown and described above. It will be understood by those skilled in the art that the present invention is not limited to the above embodiments, and that the foregoing embodiments and descriptions are provided only to illustrate the principles of the present invention without departing from the spirit and scope of the present invention.
