Detailed Description
The present invention will be further described with reference to the accompanying drawings. The utility model provides an electric switch door ware with locking function closes door, its includes that main part 1 and activity articulate the pivoted arm 2 on its top, pivoted arm 2 on still articulate and install brace 3, the trailing end connection of brace 3 has a single arm-drag 4, the single arm-drag is connected with drive arrangement, drive arrangement during operation drive single arm-drag seesaw in the main part to 2 swings of drive single arm-drag, realize opening and shutting of door ware, its characterized in that: a locking motor 5 is further arranged in the main body 1, a main shaft of the locking motor 5 is connected with a locking screw 51, and the locking screw 51 is in threaded connection with a locking nut 61 arranged on the locking push block 6; the main body 1 is also internally provided with a guide wheel frame 7 in a front-back sliding manner, two sides of the guide wheel frame 7 are arranged in guide grooves 72 on two sides of the main body 1 in a front-back sliding manner through guide posts 71, the front end of the guide wheel frame 7 is provided with a guide plate 74 extending backwards, the guide plate 74 is inserted into the locking thrust block 6, the guide plate 74 is provided with a push spring 8, the front end of the push spring 8 is propped against the guide wheel frame 7, the rear end of the push spring 8 is propped against the front end of the locking thrust block 6, when the locking motor 5 works, the push spring 8 is pushed by the locking thrust block 6 to move forwards, so that the guide wheel 73 is elastically pressed in the locking groove 41 of the pull arm 4 to play a locking role.
Two sides of the locking push block 6 are arranged in a guide groove 62 on the main body 1 in a front-back sliding mode through a positioning pin 63, and the locking screw 51 is inserted into the guide groove 62 from the rear end of the guide groove and connected with the locking push block 6.
The locking screw 51 is sleeved with a thrust sleeve 52, the thrust sleeve 52 is fixedly connected with the main body 1, and the thrust sleeve 52 limits the axial movement of the locking screw 51.
The guide plate 74 is provided with a limiting hole 75, and a limiting pin 76 passes through a limiting groove 77 arranged on the locking thrust block 6 and then is connected with the limiting hole 75 to limit the relative displacement between the locking thrust block 6 and the guide plate 74.
The pull arm 4 is provided with a rack 411, the driving device 42 on the main body 1 is connected with a gear 44 through a clutch device 43 to be meshed with the rack 411, and when the driving device 42 drives the gear to rotate, the pull arm 4 and the brace 3 are driven to move back and forth in the main body 1 through the rack 411.
The working principle is as follows: when the door needs to be opened or closed, the driving device 42 on the main body 1 drives the gear 44 to rotate through the clutch device 43, and the gear drives the pull arm 4 and the pull strip 3 to move back and forth in the main body 1 through the rack 411 during rotation, so that the hinged arm 2 is driven to swing, and the electric opening and closing of the door device is realized. Thereby being convenient for the electric control opening and closing of the equipment and needing no manual opening and closing.
Further: when the door body is closed, the locking screw rod driven by the locking motor 5 rotates, the screw rod is in threaded connection with the locking nut 61 on the locking pushing block 6, the locking pushing block is pushed to move forwards when the screw rod rotates, and in the process that the locking pushing block moves forwards, the guide wheel frame is pushed to move towards the direction of the hinged arm through the pushing spring, so that the guide wheel on the guide wheel frame is forced to be buckled into the locking groove on the hinged arm, and the locking effect on the door device is achieved. When the locking mechanism needs to be unlocked, the control system controls the locking motor to rotate reversely, and the screw rod can be used for pulling the locking push block and the guide wheel frame to move backwards, so that the guide wheel is separated from the locking groove.
Compared with the prior art, the door opening and closing structure in the present case can be at the automatic locking of closing the door to when making the product that needs the chamber door like oven, microwave oven, refrigerator with its application use, can effectively guarantee the seal of chamber door, also avoided user's maloperation such as children to open the chamber door, guaranteed equipment safety in utilization, so can extensively use widely.
In order to prevent the door body from being opened due to power supply failure or damage of a locking motor caused by dead locking of the guide wheel, the guide wheel frame and the locking push block are connected through the push spring, and power of the locking push block is transmitted to the push spring and then is elastically applied to the guide wheel frame. Therefore, when the locking push block is locked, if the door is opened by hand force, the locking groove on the hinged arm and the guide wheel are pressed mutually, the guide wheel frame moves backwards after the push spring is forced to deform, meanwhile, the guide frame 74 and the guide groove 62 are displaced relatively, and the guide wheel can still be separated from the locking groove, so that the door is opened. Of course, the locking force can be modified through the parameters of the push spring, so that the door can be locked while the door can be forcibly opened under the emergency condition, and the device cannot be damaged.
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.
