The fourth limit surface 348 and the third limit surface 347 are perpendicular to each other, and are alternately arranged with the second limit surface 346 and are parallel to each other. The first limit surface 345, the second limit surface 346, the third limit surface 347 and the fourth limit surface 348 jointly define a rotation space 340.

The unlocking unit 32 has a torsion member 35 arranged on the rear side of the lock housing 11 and extending forward to connect the linkage mechanism 2, and a torsion member 35 connected between the torsion member 35 and the lock core body 34 to be able to communicate with the The torsion member 35 drives and rotates the unlocking member 36 with each other.

The torsion member 35 has a base portion 351 for operation, and a through hole 213 extending forward from the base portion 351 through the lock housing base 11 and the intermediate base 13 and inserted in the rotating member 21的转柱部352。 的转柱部352。 The front end surface of the rotating column portion 352 is recessed with a hole 353. The unlocking member 36 is generally T-shaped, and has a rod-shaped head 361 that is rotatably accommodated in the rotation space 340 of the lock core body 34, and a head 361 extending back from the head 361 Inserted in the body 362 of the jack 353.

The bolt mechanism 4 includes a bolt housing 41 extending from the inside of the housing mechanism 1 to the left and out of the housing mechanism 1, and a sliding block extending from left to right and slidably disposed in the bolt housing 41 42, and a first locking arm 43 and a second locking arm 44 pivotally connected to the left end of the slider 42 up and down.

The bolt housing 41 has an opening 411 (as shown in FIG. 1) opened at its left end and used for the sliding block 42 to extend or retract. The sliding block 42 has a position at its right end and for the sliding rod portion 232 of the sliding block 23 to extend in to drive the sliding block 42 to move left and right. The sliding groove 421 and a telescopic space 422 at the left end of the sliding groove 421 for the first locking arm 43 and the second locking arm 44 are accommodated. The first locking arm 43 has a first hook 431 protruding upward at its left end, and the second locking arm 44 has a second hook 441 protruding downwards at its left end.

Referring to Figures 3, 4, and 5, when the new door lock structure is to be changed from the unlocked state (as shown in Figure 4) to the closed state (as shown in Figure 5), insert the key into the key hole 344 The lock core body 34 is rotated according to the arrow direction A to drive the unlocking unit 32 to rotate to drive the rotating member 21 of the linkage mechanism 2. When the rotating member 21 is driven to rotate, the connecting rod unit 22 is driven to drive the toggle lever portion 232 of the toggle block 23 to the left, and then the slider 42 is pushed to the left to the locked state.

Further, in the unlocked state, the first locking arm 43 and the second locking arm 44 are restricted by the bolt housing 41 and close to each other (as shown in FIG. 1). In the process of changing from the unlocked state to the locked state, the first locking arm 43 and the second locking arm 44 will be driven to extend out of the opening 411 as the sliding block 42 moves to the left, and then detach from the lock. The tongue housing 41 is restricted so that the first hook 431 and the second hook 441 lie up and down against the edge of the opening 411 (as shown in FIG. 2).

6 and 7, it should be particularly noted that in the unlocking state, the head 361 of the unlocking member 36 is sandwiched between the first limiting surface 345 and the second sector of the first sector 342 The third limit surface 347 of the portion 343 (as shown in FIG. 6). As the lock core body 34 is driven by the key to rotate in the arrow direction A1 shown in FIG. 6, the opening The lock member 36 is pushed by the first limit surface 345 and the third limit surface 347 to synchronously drive to the locked state (as shown in FIG. 7). Then, when the key is to be removed from the key hole 344, as long as the key is turned in the reverse direction (that is, in the arrow direction A2 shown in FIG. 7), the lock core body 34 can be driven to rotate, and the first limit The position surface 345 and the third limit surface 347 will be far away from the unlocking member 36 without driving the unlocking member 36, so that the door lock structure of the present invention is maintained in the locked state.

It is worth noting that if the torsion member 35 is rotated to change the door lock structure of the present invention between the unlocked state and the closed state, that is, the torsion member 35 is rotated in the arrow direction A3 shown in FIG. 6, The unlocking member 36 is driven by the torsion member 35 to rotate in the rotation space 340 of the lock core body 34 without driving the lock core body 34 to rotate. Specifically, the head 361 of the unlocking member 36 will be driven by the torsion member 35 to make the head 361 abut against the position of the first limiting surface 345 and the third limiting surface 347. At the position of the second limit surface 346 and the fourth limit surface 348.

It should be noted that, in order to maintain the stability of the unlocking member 36 when the rotating space 340 rotates, the width of the distance between the first limit surface 345 and the third limit surface 347, and the second limit surface 346 The width spaced from the fourth limit surface 348 is the same as the width of the head 361 of the unlocking member 36.

Referring to FIG. 8, a second embodiment of the door lock structure of the present invention has the same structure as the first embodiment. The difference lies in the positions of the rotating member 21 and the link unit 22 of the linkage mechanism 2. For the convenience of description, the following will only focus on the difference between the various embodiments The differences are described.

In the second embodiment, the rotating member 21 of the linkage mechanism 2 is arranged between the housing base 11 and the intermediate base 13 of the housing mechanism 1, and the linkage unit 22 has a position in the intermediate base. 13 The connecting rod 221 on the rear side and connected with the rotating member 21 to be driven to rotate, and a connection with its rear end connected to the connecting rod 221 and extending forward through the middle seat 13 and the bolt mechanism 4轴223. Since in the second embodiment, the change of the position of the rotating member 21 and the connecting rod unit 22 does not affect the transmission relationship between the various components of the door lock structure of the present invention, it will not be repeated here.

In summary, the bolt mechanism 4 and the lock cylinder mechanism 3 are respectively arranged in the lock housing mechanism 1 extending left and right and the lock cylinder mechanism 3 is arranged on the side of the bolt mechanism 4 The design ensures that the length of the lock cylinder mechanism 3 does not need to be shortened due to the limitation of the structure of the bolt mechanism 4, thereby improving the safety of the door lock structure. It is a rather innovative and practical creation. To achieve the purpose of costing a new style. Furthermore, through the design that the linkage mechanism 2 is connected between the lock cylinder mechanism 3 and the bolt mechanism 4, the lock cylinder mechanism 3 can indirectly drive the bolt mechanism 4, thereby avoiding the lock cylinder mechanism 3 and the lock bolt mechanism 4 The structural design of the tongue mechanism 4 is mutually restricted by each other. In addition, the first sector portion 342 and the second sector portion 343 of the lock core body 34 define the design of the rotation space 340, and the new door lock can be operated by inserting the key or operating the torsion member 35 in two ways structure.

However, the above are only the embodiments of the present invention. To limit the scope of implementation of the present model, all simple equivalent changes and modifications made in accordance with the scope of the patent application for the present model and the contents of the patent specification are still within the scope of the present model patent.
