Detailed Description

As shown in fig. 1-2 and 4-6, a linkage structure of a lock includes

A transmission member 20; the transmission piece 20 is used for being in transmission connection with a thumb wheel 50 of an external lock cylinder and is provided with a linkage hole 100;

a handle 10; the handle 10 and the transmission member 20 can rotate relative to each other, and the handle 10 is held by a user;

a first link mechanism 30; the first linkage mechanism 30 comprises a first linkage rod 31, a rotating piece 321 and a first reset elastic piece; the first linkage rod 31 is mounted on the handle 10 and is circumferentially fixed with the handle 10 so as to be capable of aligning with the linkage hole 100 as the handle 10 rotates, and it can be understood that the first linkage rod 31 and the handle 10 are relatively fixed in the circumferential direction, specifically, the circumferential direction is the direction around the central axis of the handle 10, that is, when the handle 10 rotates relative to the transmission member 20, the first linkage rod 31 can rotate with the handle 10 and rotate to the position aligned with the linkage hole 100; first linkage rod 31 is also axially movable relative to handle 10 and is capable of insertion into or removal from the aligned linkage aperture 100 when moved, it being understood that first linkage rod 31 is movable relative to handle 10 in the axial direction of first linkage rod 31 and is capable of insertion into linkage aperture 100 or removal from linkage aperture 100 during axial movement of first linkage rod 31 when first linkage rod 31 is aligned with linkage aperture 100; when the first linkage rod 31 is inserted into the linkage hole 100, the first linkage rod 31 can be driven by the handle 10 to link the transmission part 20 to rotate; it is understood that when the handle 10 is rotated, the handle 10 can drive the transmission member 20 to rotate through the first linkage rod 31 and the linkage hole 100; the rotating piece 321 is rotatably installed on the handle 10 and is in transmission connection with the first linkage rod 31; when the rotating member 321 moves towards the first direction, the first linkage rod 31 can be linked to be separated from the linkage hole 100, and the first linkage rod 31 is prevented from moving towards the direction close to the linkage hole 100; when the rotating piece 321 moves towards the second direction, the blocking of the first linkage rod 31 can be released; the first direction and the second direction are opposite directions; both ends of the first return elastic member 33 are respectively disposed on the first linkage rod 31 and the handle 10, and are used to provide elastic stress for urging the first linkage rod 31 to be inserted into the linkage hole 100.

On the basis of the structure, when in use, the driving piece 20 is connected with the thumb wheel 50 of the external lock cylinder, and the handle 10 can be rotatably arranged on the door; thus, when the rotating element 321 moves in the second direction (for example, the rotating element 321 moves in the counterclockwise direction as shown in fig. 5), the rotating element 321 releases the prevention of the first linkage rod 31, meanwhile, the handle 10 is rotated to link the first linkage rod 31 to rotate, and when the first linkage rod 31 is aligned with the linkage hole 100, the first linkage rod 31 is inserted into the linkage hole 100 under the action of the first return elastic element 33, and then the handle 10 continues to be rotated, the handle 10 is linked with the transmission element 20 to rotate through the first linkage rod 31 and the linkage hole 100, and the transmission element 20 drives the thumb wheel 50 of the external lock cylinder to rotate, so that unlocking can be achieved; when the rotating member 321 moves in the first direction (for example, the rotating member 321 moves clockwise as shown in fig. 5), the rotating member 321 links the first linkage rod 31 to disengage from the linkage hole 100, and at this time, the transmission between the handle 10 and the transmission member 20 is disconnected, so that only the idling of the handle 10 can be realized even if the handle 10 is rotated, and thus the occurrence of unlocking caused by violently rotating the handle 10 is prevented.

Above-mentioned need to explain, because first gangbar 31 is not real-time alignment ganging hole 100, if adopt linear electric motor to replace the cooperation of first elastic component 33 and rotating member 321 that resets to drive first gangbar 31 and insert or break away from ganging hole 100, at this moment, when linear electric motor drove first gangbar 31 and inserts ganging hole 100, if first ganging bar 31 is not aimed at ganging hole 100, easy emergence linear electric motor's output shaft can not stretch out and take place the dead problem of card, consequently, the utility model discloses in, adopt the cooperation of the first elastic component 33 that resets of rotating member 321, wherein, can remove the prevention to first gangbar 31 when rotating member 321 moves towards the second direction, and first elastic component 33 that resets provides the power that impels first ganging bar 31 to being close to ganging hole 100 direction motion, can avoid the card to die.
