Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0022] This utility model provides, for example Figure 1-4 The diagram illustrates a door lock core and pull rod connection structure, applied at the connection point of the door body 1, lock core 2, and pull rod 3. A mounting groove 101 is provided on one side of the door body 1, comprising:

[0023] Mounting slot 101 is provided on one side of door body 1;

[0024] The transmission assembly 4 includes a half gear 403 fixedly connected to the back of the pull rod 3. A linkage gear 402 meshes with one side of the half gear 403, and a toothed plate 401 meshes with one side of the linkage gear 402. The toothed plate 401 is fixedly connected to one side of the lock core 2. A first fixing member 6 and a second fixing member 7 are respectively provided at the bottom of the half gear 403 and the linkage gear 402. A rotating member 8 is provided at the top of the linkage gear 402.

[0025] Guide component 5 is located on one side of lock core 2.

[0026] Specifically, the guide assembly 5 includes a guide rod 501 fixedly connected to the inner wall of the front side of the mounting groove 101. A guide groove 502 is provided on the front side of the lock core 2. The guide rod 501 is inserted into the inside of the guide groove 502. The guide rod 501 and the guide groove 502 are cuboid in shape. The guide rod 501 is used to restrict the rotation of the lock core 2.

[0027] It should be noted that the guide rod 501 is rectangular in shape, and the guide groove 502 is adapted to the guide rod 501. This design restricts the movement direction of the lock core 2 and prevents the lock core 2 from moving randomly during use.

[0028] Specifically, the first fixing member 6 includes a first bearing 601 fixedly connected to the inner wall of the bottom end of the mounting groove 101, a first fixing rod 602 inserted through the middle of the first bearing 601, and the first fixing rod 602 inserted through one side of the half gear 403.

[0029] It should be noted that the first bearing 601 is an existing ball bearing. The first fixed rod 602 is fixed to the inner wall of the bottom end of the mounting groove 101 by the first bearing 601, so that the first fixed rod 602 can rotate on the inner wall of the bottom end of the mounting groove 101. The first fixed rod 602 is fixedly inserted and connected to the bottom of the half gear 403, so that the half gear 403 can rotate inside the mounting groove 101.

[0030] Specifically, the second fixing member 7 includes a second bearing 701 fixedly connected to the inner wall of the bottom end of the mounting groove 101, a second fixing rod 702 inserted through the middle of the second bearing 701, and the second fixing rod 702 inserted through the middle of the linkage gear 402.

[0031] It should be noted that the principle of the second fixing member 7 is the same as that of the first fixing member 6, so that the linkage gear 402 can rotate inside the mounting groove 101.

[0032] Specifically, the rotating component 8 includes a first fixing groove 801 opened on the top of the linkage gear 402, a torsion spring 802 inserted inside the first fixing groove 801, and a second fixing groove 803 opened on the inner wall of the top of the mounting groove 101, with the torsion spring 802 inserted inside the second fixing groove 803.

[0033] It should be noted that the first fixing groove 801 and the second fixing groove 803 are used to install the torsion spring 802. In use, when the pull rod 3 drives the half gear 403 to rotate, the half gear 403 drives the linkage gear 402 to rotate, and the linkage gear 402 drives the tooth plate 401 and the lock core 2 to move. At this time, the linkage gear 402 drives the bottom of the torsion spring 802 to move, thereby stretching and deforming the torsion spring 802. When the pull rod 3 is no longer pulled, the torsion spring 802 returns to its original shape and drives the half gear 403, the tooth plate 401 and the lock core 2 to reset.

[0034] Finally, it should be noted that the above description is only a preferred embodiment of the present utility model and is not intended to limit the present utility model. Although the present utility model has been described in detail with reference to the foregoing embodiments, those skilled in the art can still modify the technical solutions described in the foregoing embodiments or make equivalent substitutions for some of the technical features. Any modifications, equivalent substitutions, improvements, etc., made within the spirit and principles of the present utility model should be included within the protection scope of the present utility model.
