Detailed Description
In order to make the objects, technical solutions and advantages of the present invention clearer and clearer, the present invention is further described in detail below with reference to the accompanying drawings and examples.
As shown in fig. 1-4, the utility model discloses a double-point bidirectional transmission error prevention device, which comprises an error prevention base 1, a first transmission piece 2, a second transmission piece 3, an elastic key 4, a key base 5 and a gear 6; the gear 6 is arranged on a gear fixing seat 13, and the gear fixing seat 13 is fixed on the bottom surface of the error prevention seat 1 through a screw; the first transmission piece 2 and the second transmission piece 3 are arranged in the error prevention seat 1 and are respectively meshed with the gear 6 in a staggered manner; the elastic keys 4 are arranged at two ends of the anti-misoperation seat 1, the key seat 5 is arranged on the bottom surface of the anti-misoperation seat 1, and the key seat 5 is used for supporting the elastic keys 4.
By adopting the structure, the first transmission piece, the second transmission piece and the gear are all arranged in the anti-misoperation seat, the gear is meshed with the first transmission piece and the second transmission piece, and the first transmission piece and the second transmission piece can realize reverse movement through the gear; because the elastic key is arranged in the anti-misoperation seat, when the elastic key is in a normal state, the first transmission piece and the second transmission piece are locked, the door lock cannot be opened, and after the elastic key is pressed down at the same time, the transmission shifting post of the first transmission piece is rotated, so that the first transmission piece and the second transmission piece can move in opposite directions, and unlocking is realized.
Specifically, the elastic key 4 comprises a key 7 and a spring 8, wherein one end of the spring 8 is sleeved with the key 7, and the other end of the spring 8 is connected with the key seat 5; therefore, the keys are in a state of locking the first transmission piece and the second transmission piece in a conventional state, and only after the two keys are pressed downwards simultaneously, the first transmission piece and the second transmission piece can move outwards continuously, so that unlocking is realized.
Specifically, the first transmission member 2 and the second transmission member 3 are respectively provided with tooth grooves 9 meshed with the gear 6, so that the first transmission member and the second transmission member can realize reverse movement through the gear.
