Specific embodiment
Specific further instruction is made to the present invention with reference to the accompanying drawing.A kind of door opening/closing apparatus of functions of child lock, packet
It includes main body 1 and is movably hinged trigger 2 mounted thereto, be provided with accommodation groove 3 in main body 1, pull rod 4 is installed in accommodation groove 3,
Pull rod 4 and trigger 2 are movably hinged, and are additionally provided with tension spring 7 in the accommodation groove 3, tension spring 7 is connect with pull rod 4, and feature exists
In: the wheel frame 8 with spring 9 is also set up in the main body 1,8 one end of wheel frame is equipped with the foreign steamer of guide wheel 81 Yu trigger 2
Exterior feature contact, motor drive mechanism push wheel frame 8 to move by spring 9.
The lock groove 21 being recessed inwardly is provided on the outer profile of the trigger 2, motor drive mechanism is led by the promotion of spring 9
Wheel 81 is placed in the lock groove 21.
The motor drive mechanism includes the screw rod 91 driven by decelerating motor 9,94 spiral shell of nut on screw rod 91 and pressing plate 93
It connects, the pilot hole 82 is arranged on the pressing plate 93, when screw rod 91 rotates, pushes pressing plate 93 that spring 9 is forced to compress, makes
8 relative motion of wheel frame.
The spring 9 is sleeved on 8 surface of wheel frame, and one end is pressed on pressing plate 93, and the other end is pressed on wheel frame
Wheel stand 84 on.
Connecting plate 31 is also fixedly installed in the accommodation groove 3, motor drive mechanism is fixed in the connecting plate 31.
The guide wheel 81 is mounted on wheel stand 84 by guide wheel shaft 85, and 85 both ends of guide wheel shaft, which extend outwardly, is placed in main body
Sliding in guided wheel slot 86 on 1.
93 end face of pressing plate is provided with pilot hole 82, and 8 one end of wheel frame is placed in the pilot hole 82.
Working principle: when needing to open the door, trigger is rotated around the shaft of main body, realizes switch gate.It was opening the door
Cheng Zhong, trigger change with intersubjective position, and trigger generates by tie rod and tie rods tension spring 7 and resets power.When need
Will at closing time, the pulling force of tension spring 7, which pulls, occurs angle change between main body and trigger, to play automatic door-closing reset response.
Wherein, after this shutdown mechanism closes, the screw rod 91 that decelerating motor 9 drives is rotated, on screw rod 91 and pressing plate 93
Nut 94 is spirally connected, and when screw rod 91 rotates, pushes pressing plate 93 that spring 9 is forced to compress, makes 8 relative motion of wheel frame, spring 9 pushes away
Dynamic wheel frame 8 is moved to 2 direction of trigger, and the guide wheel on wheel frame is forced to be snapped into the lock groove on trigger, is played to pulling
The locking effect of machine.Wherein, spring has certain compression travel, therefore it can reduce to wheel frame movement travel precision
It is required that also avoiding leading to guide wheel because decelerating motor stroke is excessive to avoid decelerating motor because the too small locking effect of stroke is poor
Leading to associated components with lock groove hard squeeze, deformation occurs, and even decelerating motor damages.And when needing to unlock, control system
System control decelerating motor rotates backward, and can draw wheel frame using screw rod, so that guide wheel and lock groove are detached from.
On the other hand, some products need to realize secondary locking function to door body, can be continued by motor drive mechanism to pulling
Machine direction secondary motion, realizes secondary locking function.
Compared with traditional technology, closing device in this case can be in shutdown automatic locking, so that applying with it
Product such as oven, micro-wave oven, refrigerator etc. needs the product of chamber door in use, can effectively ensure that the airtightness of chamber door, also avoids
The user misoperations such as children open chamber door, ensure that equipment safety in utilization, adapt to different product requirement (product part
Scale error), it highlights automation therefore can be widely used to promote.
The above shows and describes the basic principles and main features of the present invention and the advantages of the present invention.The technology of the industry
Personnel are it should be appreciated that the present invention is not limited to the above embodiments, and the above embodiments and description only describe this
The principle of invention, without departing from the spirit and scope of the present invention, various changes and improvements may be made to the invention, these changes
Change and improvement all fall within the protetion scope of the claimed invention.
